Multi-domain Wall Configuration of Central Control Room and Gate in Port Terminal Monitoring Splicing Screen Scheme-Qunmao

Port dock splicing screen and banks, subway, high-speed rail are not the same thing. The corrosion of screen sheet metal and PCB in coastal high salt spray environment is real. BEV panorama of shore bridge, TOS operation instruction, AIS ship track and gate OCR snapshot should be partitioned with the wall. The production security network must be physically isolated from the customs/public security network. In this paper, the 21-piece 55-inch splicing screen price limit 229000 of Hefei China Eastern Airlines Wharf, the LCD monitoring wall price limit 235000 of Ningbo Zhoushan Port, the 46-inch 3.5mm bidding document of Zhenjiang Port, and the salt spray 10-level political procurement clause are used as anchor points to disassemble the configuration logic of the three-level wall structure of the central control room, gate and bulk terminal, and translate anti-corrosion selection, splicing control disassembly items and multi-domain isolation into a copy into a purchase list, and explain what should be verified when docking * * LCD splicing screen China source manufacturer * *.

1. first look at the public tender: budget anchor and salt spray clause for port procurement

The public data of the port splicing screen is more scattered than that of the airport and high-speed rail, but it is enough to push back the configuration and procurement logic.

Hefei China Eastern Airlines Terminal Cloud Port Digital Platform Display Equipment Procurement, May 2026 Inquiry, Purchase21 pieces of 55-inch splicing screen, 3 pieces of 98-inch display screen, video decoder and bracket, ceiling price229000 yuan (229020), 45 calendar days to complete the supply and installation. Bidder's Performance Requirements: Since April 2023, at least 2 LCD splicing screens with a contract amount of not less than 100000 yuan have been supplied and installed. This project corresponds to the display scene of the dock central control room/complex building, with 21 screens and a budget water level of 200000.

Ningbo Zhoushan Port Beilun Second Container Terminal Dangerous Cargo Class Information Project, July 2026 pre-publicity, procurementLCD monitoring wall system 1 set(including 1 set of splicing screen, 1 set of large screen bracket, 1 set of screen control decoding host and installation auxiliary materials), the maximum price limit235000 yuan. The key signals for this project are:Screen control decoding host as an independent device column item, not stuffed into the "screen with decoding. The newly-built team room for dangerous goods class belongs to the central control/duty room level, 235000 the structure of the decoding host with screen bracket can be directly used as the budget reference of template A.

Zhenjiang Port International Container Terminal Central Control Room Monitoring Screen, 2020 tender, purchase 46-inch LCD splicing display, patchwork≤ 3.5mm, resolution 1920 × 1080, brightness ≥ 500cd/m, contrast ≥ 1200:1, service life ≥ 60000 hours, matching H.265 HDMI decoder board, aluminum alloy mounting frame, stainless steel wire drawing hemming, including removal of original large screen and renovation of partition wall. The operating temperature and humidity of this tender is written "0 ℃ ~ 40 ℃,10% ~ 80% RH (no condensed water)"--This is a common indoor room conditions, the full text does not appear salt spray, three anti-paint, IP protection and other port anti-corrosion provisions.. Zhenjiang Port represents the conventional display configuration of the central control room of the port. Anti-corrosion is another requirement that requires separate clauses. The two cannot be confused.

The political basis of the salt spray clause.It exists in the general splicing screen policy documents. A government procurement in Hebei requires that "the metal surface of the equipment shell meets the requirement of salt spray level 10", and the report of the national recognized testing organization should be provided and stamped with the official seal. A tender in Weifang, Shandong province requires "salt spray test for the shell of LCD splicing screen products, which meets the salt spray grade 10 requirements of GB/T2423.17-2008". A project in Gansu province wrote more specifically: "the sample is placed in 5% salt solution, the test space is 48H at 35 ℃, the surface is free of blistering, cracks and rust, and conforms to salt spray grade 10". These are the basis on which the anti-corrosion clause of the port should be quoted, not the tender document of Zhenjiang Port itself.

Three-level wall-to-wall structure of 2. port: what to see and what cannot be mixed at each level

The essential difference between the port scheme and the general park monitoring is thatEnvironmental anti-corrosion coating and production net/customs net isolation layer. The BEV panorama of the shore bridge in the left area of the central control room and the berth operation picture cannot enter the wheel patrol group. The blacklist car snapshot of the gate duty station should be superimposed with the customs lock state. The picture in the customs supervision area should go through an independent decoding node and not be mixed with the wharf production security network.

The quay bridge/field bridge remote control room (automatic wharf) is a special scene: the single driver station uses special multi-screen to make BEV panoramic spreader close-up PLC status, and the large screen side only makes "remote control situation wall" for team handover and abnormal re-opening,does not replace the driver operating screen. This boundary should be clearly written in the plan, otherwise Party A will easily mistakenly think that a large screen can meet both remote control operation and situation display.

3. LCD splicing screen unit: port version parameter baseline and anti-corrosion selection

Salt spray level 10 is not mandatory for all port projects, but coastal terminals and high-humidity inland ports should be included in the control standard. A political cai in Hebei listed "the metal surface of the equipment shell reaches salt spray level 10"★The Shandong Weifang and Gansu projects also use salt spray level 10 as a verifiable technical parameter. When purchasing, suppliers should be required to provideCover Tender ModelThe salt spray test report is not a "series product compliance" statement letter.

Zhenjiang Port's bid has a statement worthy of being included in the bid: "LCD splicing display is recommended to use first-line brand products in the industry, such as Samsung, LG, BOE, etc". Panel sourcing is not a question of brand preference in port projects, but rather a guarantee of batch consistency and long-term spare parts supply. The whole wall splicing is most afraid of color difference caused by panel batch mixing, and the color difference in coastal environment will be enlarged with the use time.

4. control and decoding layer: a layer that must be listed separately in the port tender

The purchase list of Ningbo Zhoushan Port Project is clearly written: "One set of LCD monitoring wall system (including one set of splicing screen and large screen bracket,Screen control decoding host 1 setand installation of auxiliary materials) ". The decoding host is an integral part of the system, but it is an independent equipment item in the procurement structure, not a gift of "on-screen. Zhongshan Port Project also lists "1 8-channel HDMI output decoder" and 6 49-inch splicing screens in parallel. The decoder supports 64-channel 1080P image decoding and display.

• ArchitectureEmbedded hardware or distributed nodes without Windows IPC. The 7 × 24 operation of the port central control room, dust accumulation of the fan of the industrial control computer and system collapse are the main reasons for repair.
• Decoding ability according to the main stream: Write "real solution 32~64 way 1080P" instead of "maximum support". In the tender document, "support 500 access" should ask "how many channels are actually solved by concurrent main code streams".
• Multi-Business Layers: AIS ship name/MMSI, TOS box position, tally OCR result, electronic chart base chart are superimposed on layers, and no recoding delay is carried out. The H.265 HDMI decoder board configured by Zhenjiang Port is adapted to the Haikang video integrated platform, indicating that port projects usually follow the decoding ecology of the existing security platform.
• Agreement: ONVIF RTSP GB/T 28181-2022 portal crane/shore bridge private SDK.
• Coordination: Perimeter invasion, gate blacklist, shore bridge emergency stop, fire fighting, AIS cross-border → <2 secondsPlay the designated screen to adjust the flash point of the video map.
• school time: NTP calibration, alarm screenshots with frame stamp. The time alignment of port multi-system (TOS/AIS/CCTV) has practical significance for accident backtracking and handling of operational disputes.

Exclusive functional design of 5. port: anti-corrosion operation and maintenance and multi-domain wall

5.1 salt spray environment operation and maintenance mode

Coastal wharf central control room even with air conditioning, humidity fluctuations and salt spray infiltration still exist. The plan should be clearly written: single screen hot plug replacement spare parts, spare parts warehouse according to 1:20 screen; Every year, the whole wall is rechecked and inspected for salt spray corrosion appearance. The maintenance channel behind the screen is ≥ 600mm, and moisture-proof boxes and dehumidification strategies are added for coastal projects. These are not "bonus items", but are the premise for the stable operation of the coastal port screen in the design life.

5.2 gate "one car, one screen"

License plate box number OCR driver face customs lock state weighing data with the same grid superposition. Blacklisted cars entering the port → designated red screen box sound and light push customs platform. This design corresponds to the real operation rhythm of the gate attendant. The less window switching, the faster the processing speed of abnormal vehicles.

Physical isolation of 5.3 production network from customs/public security network

The network domain of port projects usually includes: production security network, customs/public security network, office network, equipment control network. Each domain decoding node is independent, and the wall end only performs partition display, and does not mix signal lines. Ningbo Zhoushan Port's use of LCD monitoring wall as an independent procurement package and Hefei Eastern Airlines project's separate procurement of video decoders show that the port procurement has structurally recognized the logic of "decoding and isolation and disassembly. If the integrator responds by pressing "splice screen with built-in decoding", the technical review stage will be identified as a deviation.

6. four copyable configuration templates and budget anchors

Template A | Container Terminal Central Control Room

Configuration: 4 × 4 or 2 × 8,46/55 inch, 3.5mm,500cd/m. One screen-controlled decoding host, with 32~64 channels 1080P. Access to berth/yard/gate IPC TOS preview AIS gateway. Support cold rolled steel anti-rust treatment, coastal projects plus salt spray 10-level shell.

Budget Reference: Hefei Eastern Airlines Wharf 21 55-inch 3 98-inch decoder bracket, price limit 229000; Ningbo Zhoushan Port LCD Monitoring Wall System 1 Set (Including Screen Bracket Decoding Host) Price Limit 235000. The comprehensive cost of the screen body spell control bracket at the level of the central control room is in the range of 20 to 250000 yuan, depending on the number of screens and the anti-corrosion level.

Template B | Bulk Terminal Central Control

Curing: ship loader, trestle, power distribution station, fire pump room. The number of decoding channels shall be calculated according to the mixture of equipment status signal and CCTV.

Budget Reference: Referring to the level of the central control room, the 3 × 3 scale screen body spell control bracket is roughly in the range of 12~180000 yuan. The signal source of the bulk cargo terminal is mainly based on the state of the equipment. The number of CCTV channels is usually less than that of the container terminal, and the budget can be moderately inclined to the control and linkage functions.

Template C | Automated Terminal Remote Control Situation Wall

Configuration: 3 x 4 or 4 x 4,55 inch, 1.7mm. Distributed node BEV splicing gateway TOS/AIS layer service. Remote control team handover, abnormal pop-up window, electronic map base map. Guangzhou Port Xingang Comprehensive Display and Control Large Screen adopts 27 industrial LCD units 3 × 9 splicing, with a control price of 490000 yuan. It is used for remote control of operations, video monitoring and system display of multiple scenes, and can be used as a budget reference for large remote control centers.

Budget Reference: The budget for the situation wall level (12-16 55-inch 1.7mm distributed control layer services) is roughly in the range of 35-500000 yuan.

Template D | Gate/bayonet duty room

Configuration: 1 x 3 or 2 x 2,46 inches, 3.5mm. License plate/box number OCR with the same screen customs network isolation node. Independent video private network, not connected to the internet.

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

1. Terminal type and location: Container/Bulk/Multi-purpose/River port; distance from coastline, annual average humidity, salt spray level. This determines whether the anti-corrosion selection is standard or optional.
2. Central control room wall surface: Net size, sight distance, floor height, load bearing, whether the window is bright. 3.5mm is more cost-effective than 0.88mm when the sight distance exceeds 3 meters.
3. Zoning and number of ways: berths, yards, gates, CFS/customs area locations; IPC total amount and coding format, and whether encoders are required for old analog points.
4. Business System Interface: TOS manufacturer, AIS data source, tally OCR system, gate license plate system, interface openness and protocol type.
5. Network Domain Status: Whether the production security network and customs/public security network are physically isolated, and whether the isolation equipment already exists.
6. Maintenance conditions: Whether to be on duty for 24 hours, spare parts to respond to SLA, whether to stop the wall for maintenance, and the width of the channel behind the screen.
7. Control List: Patchwork, brightness, CNAS report, salt spray test report (covering the bidding model), GB/T 28181 certificate, original factory authorization, construction period.

Why does 8. suggest docking LCD splicing screen Chinese source manufacturers

The acceptance logic for port projects is different from that for ordinary commercial projects: integrators can transfer goods,The model of the salt spray test report is not right, the whole wall is colored due to the mixed use of panel batches, the anti-rust treatment of the bracket is not up to standard, and the spare parts cannot arrive at the site.These four issues are critical deficiencies both in the daily operations of the control room and during project acceptance. In the trader mode, the most common problems are the salt spray report and temporary adjustment and control configuration.

A port project that can withstand questioning.LCD splicing screen China source manufacturersIt should be able to answer the following five questions:

• Does the salt spray test report cover the bidding model?: Salt spray level 10 (GB/T2423.17-2008) is often required for port and coastal projects. The model on the report must be consistent with the bidding model and cannot be replaced by a series of declaration letters.
• Patchwork measured values and CNAS report pageThe bid document of Zhenjiang Port specifies that the seam shall be ≤ 3.5mm, and the nominal value and the measured value must be consistent.
• Rust-proof treatment method of bracketThe support for coastal projects is not "cold rolled steel". Anti-rust coating, sealing wiring and grounding treatment should be reflected on the drawings.
• Can spell control/decoding be matched with response: Ningbo Zhoushan Port and Zhongshan Port both separate decoders. If the source factory can only supply screens, the integrator will have to find another decoding supplier, thus increasing the coordination cost.
• Spare parts response and full wall color correction report: The port central control room cannot stop screens such as walls. Single-screen hot-plug spare parts and factory full-wall color calibration report are the bottom line.

Shenzhen Qunmao Qunmao(szqunmao.cn) can reverse the anti-corrosion options (three-proof paint/coating/salt spray grade) and patchwork configuration according to the port tender, support OEM/ODM, and make the whole wall color correction at the factory. What needs to be clear is that the business information shows that the company was established in 2021, with 17 insured persons, and is positioned"Supplier of LCD Splice Screen to be Responsive as per Tender Configuration"It is more verfiable than claiming "port bulk delivery experience. For integrators, the "splicing unit decoding node bracket cable" is pre-adjusted and delivered by the same source factory. While the on-site debugging cycle is compressed, the salt spray report and the whole wall color correction record can be confirmed together with the configuration sheet.

For port project selection, send five questions to three candidate suppliers: Does the salt spray report cover the bidding model? Is there a CNAS patchwork test page? Can the bracket anti-rust treatment produce a drawing? Can the decoder be matched? How many days will the spare parts arrive? The two suppliers who can fully answer and attach supporting documents will enter the next round. The coastal environment is not waiting for people, and the screen body is corroded to poor contact. The whole wall of the central control room is stopped.

9. Conclusions and Selection Suggestions

• Control room: 46/55 inch 3.5mm is the pragmatic baseline of the port tender, and the coastal project uses salt spray level 10 as the shell control standard. Budget priority is left to decode the number of real solutions and spare parts. Hefei Eastern Airlines 229000, Ningbo Zhoushan Port 235000 can be used as a reference for the project.
• Gate Duty Room: 46/49 inch 3.5mm, decoding single column, independent private network. The small configuration of Zhongshan Port 78300 can be used as a budget anchor.
• Automated remote control situation wall: 1.7mm start, distributed node BEV gateway layer service. The budget ratio of the screen body is lower than that of spell control and layer docking, so don't over-allocate on the seam.
• Procurement action: For the removal of screen, decoding, bracket and isolation equipment, refer to the list structure of Ningbo Zhoushan Port and Zhongshan Port. "Spliced screen with decoding" is also a trap in the port project.
• True link: Salt spray test report (covering the bidding model), CNAS patchwork test page, bracket anti-rust drawing, decoding supporting instructions. When the four samples are completed, the basic set of technical review will be stable.

LCD splicing screen China source manufacturersThe value in the port project comes down to one sentence: let the person responsible for the salt spray report, the whole wall color correction and the rust prevention of the bracket provide the screen, instead of letting the person who transferred the goods take a series of statement letters to deal with at the time of acceptance.
