Airport Security Monitoring Spliced Screen Scheme AOC/TOC Video Wall Configuration and Bidding Parameters-Qunmao

Airport security splicing screens are not the same thing as banks and prisons. The loss of pictures by banks is a lack of records, the loss of pictures by prisons is a responsible accident, and the loss of pictures at airports may directly affect the safety of flight operations. Airside runways, taxiways and aprons are physically isolated from landside terminals and security checkpoints. Field monitoring radar and flight GIS are non-IP signals and cannot be coded and bypassed. AOC/TOC attendants should watch CCTV, radar selection, flight flow and alarm queue on one wall at the same time. Construction is also restricted by skylight period. In this paper, the public bidding data of Zhengzhou, Guangzhou and Changchun airports are used as anchor points, the configuration logic of the three-level wall structure of the airport is disassembled, the splicing, distributed control, non-IP signal access and skylight period screen change are translated into a copyable purchase list, and why the docking of * * LCD splicing screen Chinese source manufacturers * * can withstand airport acceptance more than traders.

1. first look at the real tender: airport procurement budget and specification water level

The transparency of the airport's political adoption is sufficient to push back the configuration baseline without relying on "experience" to beat the head.

Zhengzhou Airport Apron Tower Monitoring Large Screen Transformation, August 2025 Bid, Purchase24 sets of 46 inch splicing screenAnd auxiliary support, including line auxiliary material construction and installation, control price.250000 yuan (tax included), 30 calendar days after the signing of the contract. The final transaction price was 196700 yuan, and the transaction party was Henan Fengqi Information Technology Co., Ltd. This project corresponds to the apron tower/flight zone control scenario, with the budget water level at the sub-control level.

Guangzhou Baiyun Airport Security Inspection and Transportation Control Center Spliced Screen Procurement, September 2026 bidding price, splicing screen area19.44㎡, total price limit500000 yuan (tax included), covering the removal and transportation of the old screen, the installation, debugging and matching of the new screen, which will be completed in 75 calendar days. The security inspection and transportation control center belongs to the core node of the terminal landside security, and the budget level is higher than the apron sub-control.

Large screen update of Zhengzhou airport monitoring system, June 2026 bid, purchase8 decoders and 8 large monitoring screensIncluding construction and installation, control price390000 yuan (tax included), 30 calendar days to complete, and require suppliers to have electronic and intelligent engineering professional contracting grade two and above qualifications. The key signal of this project is:Decoder single column 8 sets, it was not included in “screen-embedded decoding.”

Changchun Airport AOC Joint Hall Replacement, completed in November 2025,A total of 40 screens in 5 rows and 8 columns，5 day construction period, ACC backup site command site is enabled to ensure non-stop navigation. The core value of this case is not in the budget, but in the construction organization of "not stopping flights and changing screens.

Put the four sets of data together, the classification logic of airport procurement is very clear:Apron sub-control level 250000 (24 pieces, 46 inches), security check and operation control level 500000 (19.44 ㎡),AOC overall control level volume is larger and decoding must be in a single row, skylight period screen change is a hard constraint rather than an option of the construction plan.

The three-level wall-to-wall structure of 2. airport: what to see at each level and what cannot be patrolled round.

The essential difference between the airport scheme and the general monitoring room scheme is in this section. AOC left zone: yard surveillance radar and runway incursion warningCan not enter the patrol group, TOC's security check map return and isolation area access controlCannot be mixed with the picture of the business district., the position camera of the apron sub-control must correspond to the bridge status one by one.

The key parts (oil depot, catering, navigation station, UPS room) are divided by small wall or single screen, emphasizing anti-riot shell, dustproof and independent UPS. These points usually do not pursue patchwork accuracy, but require 7 × 24 uninterrupted operation and fast spare parts response.

3. LCD splicing screen unit: airport version parameter baseline (can be used for standard administration)

The parameters of a 55-inch splicing screen are written in a political document in Henan province more finely than those in most airport bidding documents: brightness uniformity ≥ 98%, service life> 80000 hours, refresh rate support 50/60/120Hz, color restoration capability ≥ 1.07B, built-in GAMMA curve intelligent adjustment, edge shielding function intelligent removal of black edges, normal working noise ≤ 12dB, low blue light certification, andThe edge of LCD display unit adopts heat-resistant materialIn order to ensure the high temperature conditions of flat-splash seam effect. These parameters are particularly worthy of inclusion in the airport window and high temperature environment (the ground temperature of the apron can reach more than 50°C in summer).

Another detail that is easily overlooked isBracket material. A government procurement document requires the liquid crystal display unit to be made of no less than electrolytic galvanized steel, with anti-extrusion design, and the bracket to be made of no less than cold rolled carbon steel, with tensile strength ≥ 200MPa. The requirements for structural safety of the sub-control booth on the apron and the elevated installation position under the luggage hall are higher than those in ordinary indoor scenes, and the bracket cannot be treated as "standard.

4. Distributed Spelling and Decoding Matrix: The Least Savin' Layer for Airports

In the 2026 project of Zhengzhou airport, 8 decoders and 8 large monitoring screensParallel procurement, separate pricingThe structure itself is a beacon signal: decoding cannot be packaged in the screen. The airport project controller must be listed separately for three reasons: the airside radar is a non-IP signal that requires the controller to open a window for superposition; AOC requires cross-screen roaming and independent scaling of multi-service partitions; The failure of a single node in a distributed architecture does not affect the whole wall.

• Architecture: Pure hardware FPGA or distributed IP nodes, no Windows industrial PC required. Under the 7 × 24 operation environment of the airport, the dust accumulation of the fan of the industrial computer and the system crash are the main reasons for the repair.
• Decoding ability according to the main streamWrite “supports 32 to 64 channels of 1080P” instead of “maximum support.” In the tender, "support 1000 access" asks "how many main streams are decoded concurrently".
• Non-IP Signal Access: Field monitoring radar, ADS-B and security check X-ray are transmitted back to DVI/SDI/DP direct connection control device to open the window,Do not encode and then decode. The method of the ground service transportation control center of the capital airport is to connect the video monitoring and field monitoring radar signal source to the large screen system at the same time to reduce the frequency of switching screens by the attendant.
• Agreement：ONVIF RTSP GB/T 28181-2022 Security X-ray/Corridor/Access Private SDK.
• Coordination: perimeter alarm, access control demolition, security emergency stop, runway incursion → <2 secondsPlay the specified screen before and after the video GIS flash point.
• Operations and maintenance: NTP timing (docking airport clock system), serial number/temperature return, scenario plan ≥ 32 groups, log audit export.
• Expansion: Distributed node expansion, leaving 30% slot for T2/T3 expansion or point addition.

5. Airport Exclusive Functional Design: Four Things to Open up with the Bank/Institute Scheme

5.1 airside/landside physical isolation upper wall

The security net screen enters the "red area", the navigation display/commercial screen enters the "white area", and the same wall partition is divided but the windows are not dragged each other. The public security private network picture goes to the independent decoding node and does not enter the general round patrol group. This isolation logic is usually reflected in the bidding document as a VLAN ACL clause, which will be checked item by item during acceptance.

5.2 emergency mode one key cut

Daily Mode: Terminal Round Tour Empty Side Thumbnail. Emergency mode: runway incursion → full wall locking of the aircraft position. The radar circle selects the public security pop-up window to broadcast subtitles.Walkthrough ModeDriven by desensitization data, it does not affect the production network. The design of drill mode is not required in the bank and prison plan, but the airport regular emergency drill is a rigid requirement, and the supplier can be required to demonstrate as a differentiated function item during procurement.

5.3 Time Calibration and Tracing to Frame

All decoding nodes, NVRs, and splicing controllers follow the same NTP (docking airport clock system). The alarm screenshots are marked with "camera number UTC frame stamp" and should be checked by the Civil Aviation Administration/Public Security Bureau. A government document in Henan requires NTP synchronization error to be no more than 2 seconds between devices, and the clock source of airport projects is usually more stringent.

5.4 Sunroof Maintenance and Screen Replacement without Suspension

The construction organization for AOC replacement at Changchun Airport is worth writing into the tender document for reference: 5-day construction period, 40 screens, ACC backup command site, post-flight construction, seamless switching of old and new equipment. When purchasing, the supplier shall be required to provideSOP for Screen Change during Sunroof Period, including single-screen hot plug process, spare parts arrival time, emergency recovery plan. Redundant power supply for the control node and non-stop wall for card replacement are the basic requirements.

7. Site Survey List

1. AOC/TOC Wall: Net dimensions, sightlines, floor-to-ceiling height, load-bearing capacity, and whether it faces strong sunlight from a window. The window level needs to confirm the brightness selection (500 vs 700cd/m).
2. Partition IPC Statistics: total number of air side/land side/terminal/key parts, coding format (H.264/H.265/4K), and whether there are old analog points.
3. List of Non-IP SignalsInterface type and quantity of field monitoring radar, ADS-B, security check X-ray return and navigation aid lighting system. This determines the spell controller board configuration.

8. Control List: Patchwork, brightness, CNAS report, distributed architecture requirements, MTBF, factory response SLA, flame retardant/seismic instructions.

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

The acceptance logic for airport projects is different from that for ordinary commercial projects: the integrator can transfer the goods,The test report does not match the model, the panel batch mix leads to the whole wall color difference, the skylight period spare parts can not reach the field.These three things are hard injuries in the airport acceptance and operation phase. In the trader model, the most common problems are the transfer report and spare parts response delay.

An airport project that can stand up to questioningLCD splicing screen China source manufacturersIt should be able to answer the following five questions:

• Panel batch consistency: AOC's whole-wall multi-screen contrast scene has zero tolerance for color difference. Is the whole-wall aging color correction done before leaving the factory? Can the panel be traced back to its source?
• Is there a CNAS report page for the measured value of the patchwork seam?: Nominal 1.7mm and measured 1.7mm are two different things. Airport tenders usually require third party inspection reports.
• Non-IP Signal Access Case: Is the spell controller actually connected to the field surveillance radar/ADS-B/security inspection X-ray? Verifiable docking case or board specification is required.
• SOP for Screen Change during Sunroof Period: Single-screen hot plug process, spare parts arrival time, emergency recovery plan. The case of Changchun Airport with 40 screens in 5 days can be used as a reference template.
• Bracket structure scheme: The installation conditions under the overhead of the apron sub-control kiosk and the luggage hall are different. The bracket needs to produce drawings and cannot be reported as "standard wall mount".

Take Qunmao Qunmao(szqunmao.cn) in Shenzhen as an example. This kind of vertical factory has accumulated production lines in the commercial display field. The seam covers 0.88mm ~ 3.5mm. The bracket depth and distributed node slot position can be pushed back according to the airport bidding document. The whole wall aging and color calibration can be done before leaving the factory. For integrators, the "Splicing Unit Distributed Splicing Control Node Bracket Cable" is pre-adjusted and delivered by the same source factory, while the on-site debugging cycle is compressed,The CNAS joint measurement page and the whole wall color calibration report can be issued together with the configuration sheet.-- This is the most tangible delivery of the airport acceptance process.

For airport project selection, send five questions to three candidate suppliers: how to guarantee the panel batch? Is there a CNAS flat-lock measured page? What project has the non-IP signal been connected to? How many days will the spare parts arrive in the skylight period? Can the bracket not produce the drawing? The two companies that can completely answer and attach supporting documents will enter the next round, and those that cannot be answered will be screened out directly. The airport's non-stop flight construction window is only a few hours long and cannot withstand on-site waiting for spare parts or supplementary reports.

9. Conclusions and Selection Suggestions

• Apron sub-control/tower: 46-inch 3.5mm is the current political baseline, decoding is separate, and budget priority is reserved for spare parts and skylight response capacity. Zhengzhou airport 250000 level project is a reasonable anchor point.
• TOC/Security Inspection and Transportation Control: 55 inches 1.7mm, distributed control or double decoding nodes, security check and judgment map return and isolation area entrance guard curing no round rounds. The 500000-class project of Baiyun Airport can be used as a budget reference.
• AOC General Control: 0.88mm start, distributed node chassis radar/GIS gateway board, GB/T 28181 cascade to superior platform. The budget ratio of the screen body is usually lower than that of the control and platform, so don't stack too high on the screen and compress the control slot.
• Procurement action: Take "Splicing Unit Distributed Splicing Support Cable Control Software" as the overall requirement response. In the airport bidding document, "splicing screen with built-in decoding" is a trap, and decoding must be separated -8 decoders at Zhengzhou airport are signals in a single row.
• Construction Plan: SOP for screen change during skylight period and ACC backup site plan shall be given at the bidding stage, and cannot be supplemented after winning the bid.

LCD splicing screen China source manufacturersThe value in the airport project comes down to one sentence: let the person responsible for the test report, the whole wall color correction and the spare parts response during the skylight period supply the screen, instead of letting the transfer person look around for the report during the acceptance.

The parameters and budget data cited in this document are derived from the public tender documents and government procurement announcements; the final details shall be subject to the on-site project survey and the manufacturer’s test reports. When selecting the source manufacturer of LCD splicing screen in China, it is suggested to verify the CNAS splicing measured page, non-IP signal docking case, whole wall color correction report and skylight spare parts response policy first, and require the supplier to mark "satisfaction/deviation" one by one in the response document ".
