Description

Technical Field

[0001] This invention relates to the field of airport equipment monitoring and operation technology, and in particular to an airport ground anchor manhole cover operation status monitoring system. Background Technology

[0002] Airport mooring manhole covers are special heavy-duty covers installed in the airport flight area to cover and protect aircraft mooring anchors. Their operational status directly affects aircraft mooring safety, the integrity of underground facilities, and the normal operation of the airport flight area. Currently, monitoring the operational status of airport mooring manhole covers mainly relies on manual inspections. Maintenance personnel regularly conduct on-site inspections of the manhole covers in the flight area to determine whether the covers are in a closed and locked state, whether there is water accumulation inside the manhole, and whether the aircraft has been effectively hooked during mooring. However, manual inspections are inefficient, inaccurate, and have a delayed emergency response. Summary of the Invention

[0003] This invention proposes an airport ground anchor manhole cover operation status monitoring system, which solves the problems in the prior art.

[0004] The technical solution of this invention is implemented as follows:

[0005] An airport ground-anchored manhole cover operation status monitoring system includes: a manhole cover status sensor, a water level sensor, a hook status sensor, a PLC controller, and a power supply module installed inside the ground-anchored manhole cover. The signal output terminals of the manhole cover status sensor, water level sensor, and hook status sensor are connected to the signal input terminals of the PLC controller. The signal output terminal of the PLC controller is connected to the monitoring platform of the airport operation management center. The manhole cover status sensor is a magnetic induction light sensor, the water level sensor is a capacitive water level sensor, and the hook status sensor is an NFC identification sensing module. The power supply module uses a lithium battery to power the manhole cover status sensor, water level sensor, hook status sensor, and PLC controller. The PLC controller uses an embedded CH854 data processor.

[0006] Preferably, the power supply module is model TPS62745.

[0007] The working principle of this invention is as follows:

[0008] The manhole cover status sensor collects the opening and closing status of the manhole cover in real time and uploads it to the PLC controller. The water level sensor collects the water level data in the well in real time and uploads it to the PLC controller. The hook status sensor sends a "hook usage status" signal to the PLC controller after the staff confirms that the hook is fixed to the ground anchor, and sends a "hook removal status" signal to the PLC controller after the staff removes the hook.

[0009] The PLC controller filters, reduces noise, performs preliminary analysis, and makes initial anomaly judgments on the raw data to form standardized data. This standardized data is then uploaded in real-time to the airport operations management center's monitoring platform via a 4G / 5G transmission unit. The monitoring platform performs in-depth analysis, anomaly judgment, storage, and statistical analysis on the data, simultaneously pushing real-time data and anomaly alarm information to maintenance personnel. Maintenance personnel can view anomaly information through the monitoring platform and quickly proceed to the site for handling (such as adjusting sensors, closing manhole covers, draining accumulated water, and adjusting aircraft hooks). After handling is completed, the results are confirmed on the monitoring platform, and the information is synchronized back to the platform. The system updates the alarm status and records the handling information, forming a closed loop. Simultaneously, the monitoring platform generates statistical reports, providing data support for airport operations management.

[0010] The power module provides stable power to the sensors and PLC controller, adapting to scenarios where there is no external power supply in the airport flight area, ensuring continuous and stable operation of the system. It uses a high-capacity lithium battery to ensure continuous and stable operation of the sensor acquisition module and the field data processing module, with a battery life of no less than 1 year. It also has a battery power monitoring function, transmitting power data to the PLC controller in real time. When the battery power is below 20%, the PLC controller triggers a low power warning and uploads it to the monitoring platform simultaneously.

[0011] The beneficial effects of this invention are as follows: By installing dedicated sensors inside airport ground anchor manhole covers and combining them with data transmission processing, remote real-time monitoring of the manhole cover's operational status can be achieved. Key parameters such as the manhole cover's opening and closing status, water level inside the manhole, and aircraft hook status can be accurately collected. This solves the technical problems of low monitoring efficiency, poor accuracy, slow emergency response, and insufficient adaptability in existing technologies, ensuring the normal use of ground anchors and the operational safety of the airport flight area. The system can monitor multiple ground anchor manhole covers simultaneously, significantly reducing the workload of maintenance personnel, greatly improving monitoring efficiency, reducing maintenance costs, and solving the problems of low efficiency and limited coverage of traditional manual inspections. It is particularly suitable for the vast airport flight area. Attached Figure Description

The signal output terminals of the manhole cover status sensor, the water level sensor, and the hook status sensor are connected to the signal input terminal of the PLC controller, and the signal output terminal of the PLC controller is connected to the monitoring platform of the airport operation management center. The manhole cover status sensor adopts a magnetic induction light sensor, the water level sensor adopts a capacitive water level sensor, and the hook status sensor adopts an NFC identification sensing module. The power supply module uses a lithium battery to power the manhole cover status sensor, the water level sensor, the hook status sensor, and the PLC controller. The PLC controller adopts an embedded CH854 data processor.

[0016] The power supply module mentioned above is model TPS62745.

[0017] The manhole cover status sensor collects the opening and closing status of the manhole cover in real time and uploads it to the PLC controller. The water level sensor collects the water level data in the well in real time and uploads it to the PLC controller. The hook status sensor sends a "hook usage status" signal to the PLC controller after the staff confirms that the hook is fixed to the ground anchor, and sends a "hook removal status" signal to the PLC controller after the staff removes the hook.

[0018] The PLC controller filters, reduces noise, performs preliminary analysis, and makes initial anomaly judgments on the raw data to form standardized data.

After handling is completed, the results are confirmed on the monitoring platform, and the information is synchronized back to the platform. The system updates the alarm status and records the handling information, forming a closed loop. Simultaneously, the monitoring platform generates statistical reports, providing data support for airport operations management.

[0019] The power module provides stable power to the sensors and PLC controller, adapting to scenarios where there is no external power supply in the airport flight area, ensuring continuous and stable operation of the system. It uses a high-capacity lithium battery to ensure continuous and stable operation of the sensor acquisition module and the field data processing module, with a battery life of no less than 1 year. It also has a battery power monitoring function, transmitting power data to the PLC controller in real time. When the battery power is below 20%, the PLC controller triggers a low power warning and uploads it to the monitoring platform simultaneously.

[0020] This invention achieves remote real-time monitoring of the operational status of airport ground anchor manhole covers by installing specialized sensors inside the covers and combining this with data transmission processing. It accurately collects key parameters such as the cover's opening / closing status, water level inside the manhole, and aircraft hook status, solving the technical problems of low monitoring efficiency, poor accuracy, slow emergency response, and insufficient adaptability in existing technologies. This ensures the normal use of ground anchors and the operational safety of the airport flight area. Multiple ground anchor manhole covers can be monitored simultaneously, significantly reducing the workload of maintenance personnel, greatly improving monitoring efficiency, and lowering maintenance costs. It also solves the problems of low efficiency and limited coverage of traditional manual inspections, making it particularly suitable for the vast airport flight areas.

[0021] The system supports adding new sensors and expanding monitoring parameters (such as adding ground anchor corrosion monitoring and manhole cover flatness monitoring), and can adapt to the monitoring needs of various wells in different scenarios such as airport aprons, taxiways, and runway edge areas. It also supports large-scale device access, which is convenient for large-scale promotion and application in airports in the future. It has strong scalability and adapts to a variety of scenarios.
