Clicks:From the access mode of five types of business content, the layout logic of flood situation research and judgment, GIS cross-screen and patchwork matching, multi-level consultation cascade, to drill acceptance and source factory customization capabilities, the landing judgment of the splicing screen of the water conservancy and flood control command center is given.
The most expensive mistake in the water conservancy and flood control command splicing screen scheme is not that the screen is expensive to buy, but that "when the flood situation comes, the water level process line on the large screen does not match the rainfall histogram, the early warning range on the GIS is cut off by splicing, and the remote end cannot hear the instructions during the consultation".The core difference between the flood control command center and the ordinary monitoring center is not "more signals", but in three things:The timeliness of water and rain data is extremely high (stopping data may mislead research and judgment), the cross-screen continuity of a GIS map directly determines the danger judgment, and the coordination of multi-level consultation and on-site map transmission determines the scheduling efficiency.. More importantly, there are differences in the operation of "flood season" and "non-flood season" for flood control-flood season may run at high intensity for many consecutive days, low frequency use in non-flood season, and the operation requirements of screen body and system cannot be matched according to the same standard. This article is carried out in the order of "five types of content → access mode → research and judgment layout → screen wall backstepping → GIS splicing → multi-level consultation → flood season operation → drill acceptance". Each link gives the judgment of "under what conditions to establish and under what conditions to exclude" and explainsLCD splicing screen China source factoryThe actual value of direct supply in GIS cross-screen patchwork combination, non-standard bracket and flood season spare parts guarantee.
1. five types of business content: first list, then talk about access
The display content of the flood control command center can be divided into five categories according to business tasks. Each type of access method, data flow direction, display form and responsible party are different. To talk about "access through platform or API" together is equivalent to not answering how to connect.
| Business Content | Typical sources | Access mode | Display Morphology | Responsible party |
|---|---|---|---|---|
| water and rain monitoring | Hydrological monitoring platform, reservoir/river water level station, rainfall station | Data API docking or application screen collection; Refresh frequency and historical data access method need to be confirmed. | Water level hydrograph, rainfall histogram, site distribution and out-of-limit alarm | Hydrological Department Platform Vendor |
| Video surveillance | Reservoir, sluice pumping station, river video platform | Platform fetching stream → decoder → wall | Multi-screen segmentation, round-robin, zoom in on key areas | Video Platform Integrator |
| A map of GIS | Water GIS platform and flood control command system | Web page collection or GIS service docking; map hierarchy and attribution of plotting functions need to be confirmed. | Map of watershed, location of danger, warning range and superposition of rescue resources | GIS Platform Integrator |
| early warning and scheduling | Meteorological early warning, hydrological early warning, flood control command system | Platform push or application screen output; need to confirm linkage rules and priorities | Alert list, response level, scheduling command, and task execution status | Flood Control Office Platform Manufacturer |
| Video Conference | Superior/subordinate flood control department, individual soldiers/UAVs on site | Conference terminal output → matrix/processor; site map transfer via platform access | Local/remote/on-site multi-screen | Information Center Integrator |
Whether the water and rain data is API docking or picture collection determines the data refresh frequency and alarm linkage capability. Whether GIS is Web collection or service docking determines whether map scaling and plotting are smooth; Whether the early warning is platform push or polling determines whether the alarm pops up in time.The plan should specify "access mode, refresh frequency, linkage rules and responsible party" item by item, instead of "access through platform" in general ". If these four columns cannot be written clearly, they will pass the buck to each other in the later joint adjustment.
The layout logic of 2. flood situation research and judgment: not "put all five types of content on it"
The core business process of the flood control command center is "flood situation research and judgment"-dispatchers need to check the water and rain situation data, rainfall distribution on GIS and river channel reality in the video at the same time to judge whether they are over-alert, need to be transferred and whether to start emergency response. The screen wall layout must serve this research and judgment process, instead of evenly distributing the five types of content.
| Partition | Core content | Layout Requirements | What conditions must be amplified |
|---|---|---|---|
| Main Research and Judgment Area | Key data of water and rain conditions (water level, flow and rainfall) | Occupy the main screen area, map cross-screen display | When the map crosses the screen, the seam shall not cut off the river line, administrative boundary and warning range boundary. |
| Trend control area | Water level hydrograph, rainfall histogram, historical contemporaneous comparison | Adjacent to the main research and judgment area, multi-curve comparison with the screen | When the curve crosses the screen, the continuity at the patchwork joint shall be measured; the time axis must be aligned. |
| Video Live Area | Reservoir, sluice and pumping station, river course and site map transmission | Auxiliary screen area, multi-screen segmentation | When the alarm is linked, the corresponding video will pop up to the specified window. |
| Early warning dispatching area | Alert list, response level, scheduling command, and task execution | Side screen or lower edge, always | When the warning pops up, it cannot be dropped by the wheel patrol. |
| Meeting area | Remote venue, on-site map transmission and collaborative plotting | Switch or independent area when meeting | Local/remote/on-site three-view verification separately during consultation |
Reverse thrust of 3. screen wall: calculate the number of rows and columns from the net size of the hall and the line of sight.
The scale of the screen wall of the flood control command hall is determined by the wall conditions of the hall, the layout of seats and the window requirements of the research and judgment area. The starting point for backstepping is to study the draft window for the zone.
Number of candidate rows ≈ wall usable height ÷ single screen height (rounded down) Deduct maintenance space, bottom cabinet, top reservation; use nearest/farthest seat line of sight to check elevation angle and GIS label readability
Take a 55-inch single screen (about 1222mm × 696mm) as an example. A municipal flood control command hall can have a clear width of about 6 meters and a clear height of about 3 meters, with 50cm reserved at the bottom, 30cm reserved on both sides and 20cm reserved at the top: the usable width is about 5.4 meters, and 5.4 ÷ 1.222 ≈ 4.4 is taken4 columns; Available height is about 2.3 meters, 2.3 ÷ 0.696 ≈ 3.3, take3 lines. The candidate size is 4 x 3 for a total of 12 blocks. If the GIS main research area needs to display the watershed map across 2 columns × 2 rows, 12 screens can be satisfied. If the hall is smaller (e.g. 4 meters wide), it may only be 3 × 2 with 6 pieces in total, and the "trend control area" needs to be compressed into round rounds or auxiliary screens.
The county-level flood control command center is usually smaller, 2 × 2 or 3 × 2; the hall of provincial or river basin institutions may be larger, requiring more than 4 × 4, and considering the division of multi-level consultation. The number of screens is not determined by "budget" or "momentum", but by the window demand of the research and judgment zone and the sight of the seats.
4. GIS cross-screen and patchwork: the most sensitive technical matching for flood control scenes
A GIS map is the core of flood control research and judgment, and it is also the most sensitive content of patchwork. The river lines, administrative boundaries, early warning range boundaries and emergency resource points on the river basin map are all continuous lines or densely marked, and the splicing and cutting of these contents will directly affect the research and judgment.
| GIS Content | Patchwork sensitivity | conditions of establishment | Exclude/Caution |
|---|---|---|---|
| River line of basin, administrative boundary | high | The main research and judgment area patchwork priority is 1.8mm and below; Whether the measured line is cut off during cross-screen display | When the 3.5mm patchwork cross-screen displays the river line, the fracture feeling is obvious |
| Warning range boundary | high | When the warning range crosses the screen, the patchwork shall not fall at the key turning point of the boundary. | 0.88mm If the installation accuracy is not enough to cause uneven patchwork, the appearance may not be as good as 1.8mm |
| Emergency Resource Point | middle | When a point dimension crosses the screen, the patchwork must not interrupt the dimension text. | The layout can be adjusted in areas with dense points, avoiding patchwork |
| Background map (non-critical area) | low | 3.5mm can be established | No need to pay 0.88mm premium for background maps |
The joint selection of flood control command center should not only look at "0.88mm or 1.8mm", but also be done.interchange inspection: Use the real GIS picture to observe whether the river line, administrative district boundary and warning range are cut off by patchwork under the target layout; If the key line is cut off, even if the patchwork is 0.88mm, it is not valid, and the layout needs to be adjusted (so that the key content avoids the patchwork) or the patchwork grade needs to be upgraded.The millimeter number of the patchwork seam is the nominal caliber, and the interchange inspection is the acceptance caliber.
Multi-level 5. consultation and on-site map transmission: what to see locally, remotely and on-site
The consultation scene of flood control command usually involves the superior flood control department, the subordinate water management unit and the on-site individual soldier/UAV. The picture relationship of the three parties is similar to that of the emergency command center, but flood prevention has its own characteristics: on-site map transmission is often transmitted back through public network or satellite, and the delay and stability are different from those of local monitoring; The audio responsibility (who picks up the sound, who is responsible for the echo suppression) must be clearly written during the consultation.
| View | Typical content | Key points of verification |
|---|---|---|
| Local screen wall | GIS research map, water and rain data, local video, remote venue, live map transmission | Confirm which windows to share and which to mask before sending to the remote end |
| Remote Venue | Local shared research screen, remote own screen | The sharing range is controllable; the far-end text is readable; the audio is clear and no echo |
| On-the-spot map transmission | Individual soldier, UAV, vehicle-mounted backhaul | The delay of public network/satellite link is acceptable; the simultaneous access of multi-channel image transmission is not stuck; the time difference between the image transmission screen and the local monitoring screen can be identified. |
The access of on-site map transmission is a high-frequency scene unique to flood control. The plan should confirm: the number of concurrent access channels of the map transmission platform; Whether the bandwidth of public network and satellite link supports multi-channel simultaneous backhaul; The delay difference between the picture transmission screen and the local monitoring screen; The reconnection time after the picture transmission is interrupted."Mobile phone can see" is not equal to "can on the big screen"-To put the picture on a large screen, it needs to go through the complete link of platform access, transcoding/decoding and wall climbing, instead of putting the mobile phone picture on.
6. Flood Season Operation and Data Aging: Two Hard Constraints Special to Flood Control
Operation difference between flood season and non-flood season
The operation intensity of the flood control command center varies with the flood season. Flood season may be continuous for many days 7 × 24 high-intensity operation, non-flood season may be low-frequency use. The operation requirements of the screen body and the system cannot be matched according to the same standard: the screen body should meet the working temperature, heat dissipation and brightness maintenance requirements for continuous operation in flood season; The failure recovery requirements of decoder and processor should be improved in flood season; The supply of spare parts should consider the characteristic of "unable to wait" in flood season, and the key spare parts should have local inventory or quick response commitment.
Timeliness of water and rain data
The refresh frequency and stop of water and rain data are directly related to the accuracy of the judgment. The plan should confirm the data refresh cycle of water level, flow rate and rainfall. When the data exceeds the update cycle and is not refreshed, whether there is a "data may expire" prompt on the big screen. Whether the alarm linkage is based on the data threshold or manual confirmation.Stopping data is used as real-time data for research and judgment, which is one of the most dangerous risks in flood prevention scenarios.
If the rainfall distribution and water level station data on GIS come from different data sources and refresh frequency is different, it may appear that "the rainfall on the map has been updated and the water level data next to it is still half an hour ago. In the plan, you should check whether the timestamp of each data source is visible and whether there is a unified "data update time" prompt. The same screen display is not equal to data synchronization, flood control research and judgment need to be especially vigilant.
7. budget trade-offs and source plant value
Flood control project budgets are usually limited, and the recommended order of choice is:First, the stitching and readability of the GIS main research and judgment area (the core of the research and judgment is the map), then the timeliness prompt and alarm linkage of water and rain data, then the access capability of video and map transmission, and finally the configuration of conference audio and auxiliary screen. Don't sacrifice the size of the main research area for the patchwork upgrade of the auxiliary screen-the GIS map can be seen clearly, which is more important than the appearance of the auxiliary screen.
qunmao LCD splicing screen china source factoryThe value of direct supply is reflected in three specific links in flood control projects. First,GIS cross-screen patching and size combination: The main research and judgment area needs map cross-screen display. The stitching grade and single-screen size should be customized according to the net size of the hall and the research and judgment line of sight. The source factory can be combined according to project requirements in 43-75 inch, 8mm to 0mm gears, instead of in standard products. Second,Non-standard bracket and installation adaptation: The wall conditions, cabinet depth and maintenance space of the flood control command hall are different. The floor cabinet, front maintenance bracket or non-standard reinforcement scheme need to be customized according to the site. Third,Flood season spare parts support: Flood season screen or module failure can not wait, the source factory spare parts supply and response than traders can control. Take Qtenboard as an example. Its public information shows that it has a self-operated manufacturing base and supports OEM/ODM/CKD/SKD cooperation mode. The panel has undergone 48-hour aging test and color calibration. The product is designed for 24/7 monitoring scenarios. For integrators and water conservancy project stakeholders, this meansNo need to configure in the "standard screen standard bracket", but according to the actual layout of the flood control hall to choose the stitching, size and installation method;Flood season spare partsIt is also more controllable than that of traders. The assessment should verify the factory qualification, panel source and actual case, rather than just look at the "factory direct supply" four words.
8. drill acceptance: complete the whole system with one flood situation research and judgment process
The acceptance of the flood control command center cannot only test "the power is turned on and the signal can go up the wall". Should be designed once.Flood situation research and judgment exercise, run the complete process of "data viewing → GIS research and judgment → video verification → early warning release → consultation and scheduling → on-site map transmission → recovery.
| Phase | Exercise Action | Key points of verification |
|---|---|---|
| Data View | Retrieving water level, flow and rainfall data of a certain basin, displaying process line and bar chart | Data refresh is normal; timestamp is visible; curve is continuous across screen |
| GIS Judgment | Locate the danger point on a GIS map, and check the warning range and surrounding rescue resources. | The map is not broken across the screen; the warning boundary is distinguishable; the point mark is readable. |
| Video verification | Take the video near the danger point and compare it with GIS position. | Fast response to video retrieval; distinguishable picture; corresponding to GIS position |
| Alert Release | Simulate trigger warning, observe large screen pop-up and response level display | The warning pops up in time; it will not be knocked off by the wheel patrol; the response level is eye-catching. |
| consultation scheduling | Initiate tripartite consultation with superior, subordinate and on-site to share the research and judgment picture | Three views with correct content; remote text readable; clear audio |
| On-the-spot map transmission | Access to individual/unmanned aerial vehicle picture transmission, on the same screen as the local picture | The image transmission delay is acceptable; multiple simultaneous access is not stuck. |
| Data stop more | Simulated water and rain data stop updating | Large screen displays "data expired" prompt; not mistaken for real-time |
| Restore | End the exercise and restore the daily layout with one key. | Layout restored to standard state; correct contents of each window |
9. common mistakes
- Myth 1: Distribute the five types of content equally and do not draw the research and judgment process. The core of flood control research and judgment is "comparison". The layout should allow GIS, data, and video to complete the comparison within the same line of sight, rather than an average screen.
- Misunderstanding 2: GIS only looks at the number of millimeters of patchwork across the screen, and does not do interruption inspection. If the 0.88mm patchwork seam cuts off the river line or warning boundary, the impact may be greater than 3.5mm falling on the blank area. The acceptance shall measure whether the key line is cut off.
- Misunderstanding 3: "Access through the platform" as an access scheme. The access method, refresh frequency, linkage rules and responsible parties must be specified item by item, otherwise they will pass the buck to each other during joint adjustment.
- Misunderstanding 4: It is believed that "mobile phones can read pictures and transmit pictures" can be displayed on a large screen. The large screen on the image transmission screen needs to go through the complete link of platform access, transcoding/decoding, and wall-up, and check the concurrency and delay of multiple channels.
- Myth 5: Ignoring the risk of data stops. If there is no prompt when the water and rain data stops, it may be mistaken for real-time data for research and judgment. The large screen should display the data timestamp and expiration prompt.
- Misunderstanding 6: spare parts are not reserved in flood season. Flood season screen or module failure can not wait. Key spare parts should have local inventory or rapid response commitment, and the source factory's spare parts guarantee is more reliable than that of traders.
10. FAQ
Flood control command center splicing screen general several pieces?
There is no standard answer. First draw the draft window of the research zone (GIS main research zone, trend control zone, video live zone, early warning dispatch zone, conference zone), then use the net size of the hall to reverse the number of candidate columns and rows, and check the readability of GIS tags and data with the nearest/farthest agent's line of sight. County level may be 2 × 2 or 3 × 2, municipal level may be 4 × 3 or 4 × 4, and provincial or river basin institutions are larger.
GIS a map across the screen, patchwork how to choose?
According to the judgment of interruption inspection, not only the number of millimeters. When the river line, administrative district boundary and early warning range of the main research area cross the screen, the patchwork priority is 1.8mm and below; During acceptance, use the real GIS screen to observe whether the key lines are cut off. If the 0.88mm patchwork installation accuracy is not enough to cause poor uniformity, the appearance may not be as good as 1.8mm.
How does water and rain data go up the wall?
It is usually data API docking or application image collection, depending on the capability of the hydrological platform. You need to confirm the refresh frequency, historical data review method, alarm linkage rules, and whether there is a visible prompt when the data is stopped. The responsible party for data access is the hydrological department or platform manufacturer, and the display system is responsible for presentation.
How to get the scene map on the big screen?
Access through the graphic transmission platform, and then transcode/decode on the wall. It is necessary to confirm the number of concurrent access channels of the image transmission platform, the bandwidth of the public network/satellite link, the stability of multi-channel simultaneous backhaul, and the reconnection time after the image transmission is interrupted. "Mobile phone can see" does not mean "can be on a large screen", the complete link should be verified.
What is the difference between the operating requirements of flood season and non-flood season?
During the flood season, 7 × 24 high-intensity operation may be possible for many consecutive days. The screen body and system shall meet the temperature, heat dissipation and brightness maintenance requirements for continuous operation; key spare parts shall have local inventory or rapid response commitment. It can be used at low frequency in non-flood season, but the inspection process of restarting the screen after long-term shutdown should also be written into the operation and maintenance plan.
What is the use of the source factory for flood control projects?
Three points: GIS cross-screen patchwork and size can be customized according to the net size of the hall and the line of sight combination; Non-standard brackets and cabinets can be customized according to site conditions; The supply of spare parts in flood season is more reliable than that of traders. Review factory qualification, panel source and actual case during assessment.
XI. Conclusion
The judgment chain of the water conservancy flood control command splicing screen scheme can be compressed into six steps:
List the access methods of the five types of content → draw the research and judgment process to determine the layout → push back the screen wall with the net size of the hall → check and determine the seam according to GIS interruption → nuclear multi-level consultation and on-site map transmission → use flood situation to study and judge the drill for acceptance.
The professionalism of the screen wall of the flood control command center is not "how big the screen is and how narrow the seam is", but inThe river line and warning boundary on GIS are not cut off by patchwork, the time axis of water level process line and rainfall histogram is in line, the data stop is more visible, the far end can hear clearly during the consultation, and there are spare parts when the flood season is broken.. The four constraints of "high-intensity operation in flood season, timeliness of data, multi-level consultation and on-site map transmission" unique to flood control determine that the scheme cannot copy the template of ordinary monitoring center. Write these judgments into the research layout, access method table, patchwork interruption check and drill acceptance script, and then use it.LCD splicing screen China source factoryThe large screen of the flood control command center is not "installed for inspection", but the command view that dispatchers really rely on to judge the flood situation and issue instructions.
Study and judge the process to determine the layout, GIS cut off to determine the seam; Data stop should be prompted, flood season spare parts can't wait.
