Forest Fire Prevention Monitoring Splice Screen Scheme Forest Farm Command Center Configuration and Double Spectrum Linkage-Qunmao

The forest fire prevention splicing screen is the easiest one in the series to write too much. The front-end dual-spectrum pan-tilt determines "whether fire can be found or not", and the AI pyrotechnic recognition algorithm determines "whether fire can be found or not". The splicing screen is only the terminal for display and scheduling in the command center. The announcement of the price comparison and transaction of Shiyan Niotoushan Forest Farm in 2025 is very clear:Haikangweishi 55-inch 1.7mm splicing screen, 1 piece sold for 48360 yuan. This is the budget water level of the screen body controlled by the forest farm level, not the unit price of the 4 × 8 wall of the provincial platform. In this paper, GB/T 47058-2026 national standard, Heilongjiang double-spectrum bidding parameters and Shiyan forest farm transaction data are used as anchor points to clarify the configuration logic of the forest fire prevention screen:The screen body is sufficient. What really determines the success or failure of the project is the selection of front-end equipment and platform interface constraints., and explain what to verify when docking * * LCD splicing screen China source manufacturer *.

1. first look at the public data: the budget structure of the forest fire prevention project and the water level of the screen body.

In the purchase list of forest fire prevention projects, the splicing screen is rarely the leading role, but its budget level is well documented.

Shiyan City State-owned Niutou Mountain Forest FarmDecember 2025 Forest Fire Video Surveillance System Upgrade Price Deal:Haikangweishi 55-inch 1.7mm splicing screen, quantity 1, transaction price 48360 yuan, delivery period of 3 days, the original factory warranty. This is a screen unit price anchor point for forest farm level sub-control. One screen corresponds to the demand for single-screen segmentation or small-scale display in the duty room, not the large wall of the command center.

Beijing-Hebei Forest Fire Prevention Cooperation Project 1-Monitoring and Large Screen, June 2025 Bid, Total Amount3.12 million yuanThe procurement includes monitoring and large screen, which will be completed within 4 months after the contract is signed. This volume corresponds to provincial/cross-regional platform-level projects. The large screen is part of the overall system. The screen budget needs to be calculated separately according to the actual configuration.

Junzhuang Town Forest Fire Prevention Command Platform Project, the winning bid amount2.013 million yuanThe purchase list clearly includes "LCD splicing screen, LCD screen bracket, 4K decoder", which is juxtaposed with dual-spectrum medium-mounted pan-tilt camera (core product) and management platform (core product). Description of the structure of this project:Spliced screens and decoders are independently purchased items and are not packaged in "Screen with Decoding"., separately priced from platform software and front-end equipment.

When the three groups of data are put together, the classification logic of the forest fire prevention screen is clear:The forest farm controls a 55-inch 1.7mm screen of about 48000mm, the overall budget of the town-level command platform including splicing screen and decoder is at 2 million level (including front end and platform), and the provincial/cross-regional projects are above 3 million.The unit price of the screen body can refer to Shiyan's 48000/block, but the overall project budget cannot be simply converted according to the number of screens-front-end dual-spectrum equipment and platform software account for the majority.

2. screen parameters: enough, no need to pile up

1.7mm is a pragmatic choice in the forest fire prevention command center, and the transaction model of Shiyan Forest Farm is this specification. The sight distance of the command center is usually 2~3 meters, and the 1.7mm patchwork has an acceptable impact on the continuity of GIS maps and bi-spectral images. The premium of 0.88mm in this scene is not worth it-GIS fire coordinates and temperature readings will not become easier to read because the patchwork is 0.8mm narrower. 3.5mm is sufficient in the sub-control or small duty room. When the visual distance exceeds 3 meters, the naked eye's perception of patchwork is obviously reduced.

The forest fire prevention command center is usually air-conditioned and conventional indoor environment, and does not require special configurations such as explosion-proof, salt spray, and wide temperature. If the command room is located at a high altitude or a forest farm without air conditioning, a wide temperature model (0~45 ℃) can be selected, but this is not standard. The humidity in the southern forest area is high, and PCB three-proof paint can be used as an option, but it is not necessary to write salt spray level 10 into the control standard like the port.

3. front-end equipment is the core of the forest fire prevention project: a hard indicator of the dual-spectrum pan-tilt.

The picture displayed on the large screen of forest fire prevention comes from the front-end double-spectrum pan-tilt. No matter how expensive the screen is, the front end is not good. The large screen is a black screen or a paste screen. The public bidding documents have very specific requirements for dual-spectrum pan-tilt. These are the core parameters that integrators need to confirm with Party A before sales.

thermal imaging detector:A tender in Heilongjiang requires infrared movement resolution.640×512, Support 2 times electronic zoom, thermal imaging lens non-thermal design,-40 ℃ and 60 ℃ work normally. A tender in Shandong requires pixels ≥ 384 × 288, pixel size ≤ 17um,NETD ≤ 40mk@F1.0. A tender in Guangdong requires a thermal imaging detector with a resolution of 400 × 300 and a fire detection distance of not less than 6000m (target 2m × 2m).

Visible light:Shandong bidding requires image resolution ≥ 4 million pixels, starlight level ultra-low illumination color ≤ 0.0002Lux, visible light lens focal length ≥ 300mm, and optical magnification ≥ 56 times. Heilongjiang tender requirements lens focal length range of 12.5~750mm, support optical fog.

Fireworks identification indicators:Heilongjiang bidding is very detailed: fireworks identification minimum pixel ≤ 36 pixels, area ≤ 5m × 5m thick smoke (5km radius); The minimum area of hot spot alarm ≤ 1.5m (5km radius);The visible light false alarm rate is not more than 2 times.; Missing negative rate ≤ 1 ‰. These are the real control punctuation points of forest fire prevention projects, which are much more important than screen stitching.

Positioning accuracy:Heilongjiang bidding requirements "in the geographic information system environment support, the monitoring target and alarm target latitude and longitude positioning",Positioning error is not more than 100m, and can link the data platform. This means that the front-end equipment itself has positioning capability, and the GIS fire point coordinates on the large screen are pushed from the front-end or platform, not calculated by the screen body.

Protection level:Guangdong bidding requires that the PTZ protection level is not less than IP66. Heilongjiang bidding requires Yuntai IP67, equipment compartment shield IP68, nitrogen-filled shield and salt spray prevention. The forest environment varies greatly, the north needs to consider low temperature and sandstorm, the south needs to consider humidity and lightning strike, protection level and lightning protection are the key to the front-end selection.

National standard basis: GB/T 47058-2026 "Technical Specification for Video Monitoring System for Forest and Grassland Fire Prevention" was implemented on May 1, 2026. It stipulates the composition, functional requirements and performance requirements of the system, and is suitable for design and testing. The standard was drafted by Zhonglin Xinda, Northeast Forestry University, Hikvision, Huawei, etc., and is the top-level basis for the technical terms of the forest fire prevention project. At the time of purchase, it should be confirmed that the bid product meets the standard, instead of just writing "in line with the bid".

Interface between 4. Large Screen and Platform: Real Technical Difficulty of Forest Fire Prevention Scheme

The large screen itself does not generate fire data, its value lies inDisplay the fire alarm, GIS coordinates and bi-spectral images pushed by the platform with the correct partition and priority.. The interface constraints of this data link are much more important than the screen body parameters.

Push mode of 4.1 AI alarm

After the front-end dual-spectrum device detects abnormal high temperature or smoke, the alarm information needs to be pushed from the platform to the split controller or decoder on the large screen side. The push method is usually protocol events (such as alarm events of GB/T 28181 and platform proprietary protocols) or API interfaces. Integrator needs to confirm:Does the platform support pushing alarm events to third-party controllers? What are the pushed fields (base station number, fire point coordinates, confidence level, and screenshots)?If the platform only supports its own client pop-up window and does not support external push, the large screen linkage cannot be done, and the attendant can only switch the screen manually.

Superposition of 4.2 GIS Fire Point Coordinates

The GIS partition on the large screen needs to display the fire point coordinates, base station coverage circle, and terrain elevation. These data come from the platform's GIS services and are displayed through layer overlays or independent windows. Heilongjiang bidding requires front-end equipment to "set and choose to superimpose the current longitude and latitude coordinate information of the target object on the monitoring screen", indicating that the coordinate information can be extrapolated. The large screen side needs to be confirmed:In what format is the GIS layer output (picture stream, vector layer, or HDMI projection screen of a separate workstation)?The simplest approach is a separate output of the GIS workstation all the way HDMI to the spelling controller, but will increase the cost of a device and maintenance.

4.3 bi-spectral pictures each accounted for one decoding

The thermal and visible light of each base station are two independent video streams. The number of front-end roads for forest fire prevention projects is usually less than that for urban security (a few to dozens of base stations in a forest farm),The number of decoding paths shall be calculated according to the number of base stations × 2. The decoding capacity of one screen in Shiyan Forest Farm is limited, but the decoder of the town/county command center needs to cover the dual-spectrum streams of all base stations. When purchasing, the number of decoding paths shall be calculated according to "number of base stations × 2 × 1.3", leaving room.

5. three copyable configuration templates

Template A | Forest Farm Sub-control/Small Duty Room

Configuration: single 55-inch 1.7mm splicing screen (or 2 × 2),500cd/m. Decoder 1, covering 4~8 base station double spectrum (8~16). Connect GIS workstation HDMI and platform alarm push. Layout: GIS half-screen base station round patrol alarm pop-up window.

Budget Reference: Shiyan Niutou Mountain Forest Farm 55 "1.7mm Single Screen Transaction 48360 yuan. The 2 × 2 scale (4 screens) screen cost about 190000, plus decoding and bracket, the comprehensive cost is roughly in the range of 22 to 260000 yuan.

Template B | Town/County Command Center

Configuration: 3 x 3 or 3 x 4,55 inch, 1.7mm. 2 decoders or 1 video integration platform, covering 15-30 base stations with dual spectrum (30-60 channels). It is connected to GIS workstation, AI platform alarm push and superior cascade. Layout: GIS left zone, double spectrum, middle zone, alarm/weather, right zone.

Budget Reference: Junzhuang Town Project 2.013 million includes front-end dual-spectrum pan-tilt, splicing screen, decoder, platform, construction and other overall contents, of which splicing screen and decoder are only part. The budget of the 3 × 3 scale screen decoding bracket is roughly in the range of 25~350000 yuan, depending on the number of decoding paths and the GIS screen projection method.

Template C | Provincial/Cross Regional Platform

Configuration: 4 x 6 or 4 x 8,55 inch, 1.7mm or 0.88mm. Distributed spell control cluster cascade server. The province's GIS fire risk thermal diagram alarm convergence. Satellite remote sensing, drone return.

Budget reference: Beijing-Hebei cooperation project 3.12 million includes monitoring and large screen as a whole, and the large screen part needs to be calculated separately according to the actual wall type and seam. Provincial platforms have a large number of screens, but the proportion of screen budgets is usually lower than platform software and cascade development.

6. Site Survey List (can be sent directly to Party A before sales)

1. Command Center HierarchyForest farm sub-control/town level/county level/provincial level. Wall net size, sight distance, bearing. When the sight distance exceeds 3 meters, 1.7mm is sufficient, and 0.88mm is not necessary.
2. Number of front-end base stations and dual-spectrum brands: Number of base stations × 2 Number of decoding paths. Confirm whether the front-end has been tendered or has a brand, affecting the platform interface docking.
3. Platform status: the brand of the existing forest fire warning platform, whether the extrapolation of alarm events is supported, and the GIS data output format. This determines whether the large screen linkage can be achieved.
4. AI pyrotechnic identification index: false positive rate, false negative rate, minimum recognition pixel. These are the control punctuation points of the front-end equipment, not the screen body.
5. Cascading Requirements: Whether to push to the county/city/province platform, whether the cascade protocol is GB/T 28181 or forest and grass private network.
6. Environmental conditions: Whether the command room is air-conditioned and whether it needs wide temperature/moisture-proof matching. Lightning protection of power supply shall be confirmed in case of multiple lightning strikes in forest area.
7. Control List: patchwork (1.7mm/3.5mm), brightness, number of decoding solutions, platform alarm push interface, GB/T 47058-2026 compliance.

Why does 7. suggest docking LCD splicing screen Chinese source manufacturers

The focus of screen body verification of forest fire prevention projects is different from that of ports and petrochemicals:Salt spray report and explosion-proof certificate are not required, but CNAS page of the measured value of flat-spliced seam, description of double-spectrum calculation of the number of decoding paths, and color correction record of the whole wall are required.. In the trader mode, the most common problems are the transfer report and temporary mediation code configuration.

One that can withstand the questioning of forest fire prevention projectsLCD splicing screen China source manufacturersIt should be able to answer the following five questions:

• 1.7mm Patchwork measured value and CNAS report page: Shiyan Forest Farm has a transaction model of 1.7mm, and the nominal value and measured value must be consistent.
• The number of decoding paths is calculated by double spectrum × 2.: instead of reporting a general "support XX road" according to the number of base stations, it is necessary to write clearly how many 1080P roads can be solved by a single station and how many base stations can be covered in a dual spectrum scenario.
• Whether the spell controller supports external alarm event access: Can the fire alarm pushed by the platform trigger the designated screen pop-up window or can only manually cut the screen. This needs to be confirmed jointly by the spell controller and the platform manufacturer.
• Can the bracket be customized according to the space of the command room?: Before maintenance or after maintenance, channel width, need to draw drawings.
• Spare parts response and whole wall color correction record: The command center cannot stop screens such as walls. Single-screen hot plug and factory color calibration records are the bottom line.

Shenzhen Qunmao Qunmao(szqunmao.cn) can reverse the seam specification and decoding configuration according to the bidding document of the forest fire prevention command center, cover the 1.7mm ~ 3.5mm seam, and leave the factory with the whole wall color correction, supporting OEM/ODM. It should be clarified that publicly available business registration information shows the company was established in 2021 with a registered capital of RMB 2 million, and its positioning is as…"Supplier of LCD Splice Screen to be Responsive as per Tender Configuration"It is more able to withstand verification than claiming that "forest fire prevention industry is deeply cultivated. The core of the forest fire prevention project lies in the front-end dual-spectrum equipment and platform software. The screen body is a supporting display terminal. The screen factory cannot unilaterally promise the compatibility of the platform interface-this needs to be confirmed by the three parties in the selection stage and the platform manufacturer.

Forest fire prevention type selection, send five questions to three candidate suppliers: 1.7mm patchwork CNAS report page is there? How to calculate the number of double-spectrum decoding? Is the splicing controller connected to the platform alarm push? Can't the bracket out of the drawing? How many days will the spare parts arrive? The two companies that can answer completely and attach supporting documents will enter the next round. The parameters of the front-end double spectrum and the platform interface, in addition, confirm with the front-end manufacturer and the platform manufacturer respectively, do not regard the screen factory as an all-round player.

8. Conclusions and Selection Suggestions

• Forest farm sub-control: 55 inch 1.7mm single screen or 2 × 2, decoding is configured according to the number of base stations × 2. The budget refers to the screen water level of 48000/block of Shiyan Forest Farm.
• Town/County Command Center: 55 inch 1.7mm,3 × 3 or 3 × 4, decoding covers 30~60 channels of double spectrum. The screen budget is 25~350000 levels, and the platform interface is confirmed by three parties in the selection stage.
• Provincial Platform: Screen specifications are selected by sight distance and partition, and the budget ratio is lower than that of platform software and cascade development. Beijing-Hebei 3.12 million level projects can be used as a whole reference, screen body separate accounting.
• Procurement actionScreen, decoder, and bracket – separate items. The Junzhuang Town project purchases LCD splicing screen, bracket and 4K decoder in parallel. This structure can be directly referenced.
• True link: CNAS patchwork measured page, double spectrum decoding accounting instructions, platform alarm push interface confirmation, bracket drawings. With all four elements in place, the foundation for the technical review is essentially solid.

LCD splicing screen China source manufacturersThe value in the forest fire prevention project comes down to one sentence: let the person responsible for the splicing report, the whole wall color correction and the double spectrum decoding accounting provide the screen, instead of letting the person who transferred the goods take a series of statement letters to deal with during the acceptance. Front-end double spectrum and platform AI, to the professional people.

The parameters and data of this article are quoted from the public bidding documents, national standards and government procurement announcements, and the specific project site survey and manufacturer's inspection report shall prevail. GB/T 47058-2026 "Technical Specification for Video Monitoring System for Forest and Grassland Fire Prevention" will be implemented on May 1, 2026. It is recommended to confirm that the bidding system meets the standard during procurement. LCD splicing screen China source manufacturer-qunmao.
