Description

Technical Field

[0001] The invention relates to the technical field of monitoring devices associated with the safety of aircraft operation at an airport, and in particular to a tiltable airport perimeter monitoring device. Background Art

[0002] The airfield is a place for aircraft to take off, land, taxi and park, including runways, take-off strips, runway end safety zones, taxiways, aprons and areas around the airport with restricted obstacles. It is one of the areas with the highest security level in the airport. According to the "Security Facilities for Civil Transport Airports" (MH / T7003-2017), the airport perimeter with security levels of Class I and Class II should be equipped with intrusion alarm systems and video surveillance systems to ensure the safety of aircraft operations in the airfield.

[0003] At present, the front-end devices installed on the fences of the intrusion alarm systems used by domestic airports mainly include: vibration detectors, microwave radars, vibration cables, vibration optical cables, etc. Since the airport runway is located in an open area with relatively stable wind direction all year round, in special weather conditions such as strong winds, heavy rains, lightning, hail, etc., the physical fences are frequently shaken by external influences or vibrated by rain, hail, branches, flying sand and rocks, etc., and the intrusion alarm system with vibration detection as a technical means has a very high false alarm rate under special weather conditions.

[0004] In order to solve the problem of false alarm rate of intrusion alarm system with vibration detection as a technical means, the main technical means currently used is to dynamically adjust the intrusion alarm detection sensitivity according to the changes of environmental factors, and automatically analyze and identify the intrusion alarm signal: first, the intrusion alarm system is connected to the airport meteorological observation system, and the detection sensitivity of the intrusion alarm system is automatically adjusted according to the changes of environmental factors such as wind volume, rainfall, and vibration frequency of the enclosure to reduce the false alarm rate. Then, AI artificial intelligence technology is used to automatically analyze and review the alarm signal and video surveillance signal to identify the real intrusion alarm signal. However, since the airport meteorological observation system is far away from the physical enclosure, it is impossible to accurately monitor the dynamic environment around the physical enclosure. The intrusion alarm system has a large error in controlling the detection sensitivity. When the intrusion alarm system receives more frequent alarm signals, the system response speed cannot meet the needs of AI artificial intelligence technology, and the alarm signal cannot be accurately identified, and the false alarm rate of the intrusion alarm system cannot be effectively controlled. Therefore, how to accurately monitor the dynamic environment around the physical enclosure and timely control the detection sensitivity of the intrusion alarm system has become one of the key issues in how this technical solution can effectively reduce the false alarm rate of the intrusion alarm system.

[0005] On the other hand, the front-end equipment of the airport perimeter intrusion alarm system mainly includes: perimeter security control box, monitoring pole, infrared monitoring camera, speaker, lamp pole and auxiliary lighting, alarm detector, etc. The devices and equipment in the perimeter security control box mainly include: circuit breaker, voltage stabilizer, power conversion module, network switch, power amplifier, I / O controller, illumination sensor, alarm processor, protocol converter, temperature and humidity sensor, heater, etc. Due to the influence of the transmission distance of the weak current cable of the front-end equipment, such as: the maximum transmission distance of the twisted pair does not exceed 90m, and each line of the alarm processor front end of the vibration detector generally does not exceed 72m, the transmission and control range of the perimeter security control box to the front-end equipment is usually designed to be about 120m of the physical perimeter straight line distance. Therefore, how to change the configuration of the existing perimeter security control box and its transmission mode with the front-end equipment, extend the transmission distance, optimize the system structure, save materials and costs, is also a technical problem to be solved at present.

[0006] Another technical problem with the airport perimeter intrusion alarm system is whether the horizontal arm of the front-end monitoring pole should extend outside the physical perimeter: if the horizontal arm of the monitoring pole is only set on the inside of the physical perimeter, it is impossible to effectively monitor the warning area within 5m outside the physical perimeter due to the obstruction of the physical perimeter. If the horizontal arm of the monitoring pole extends outside the physical perimeter to install infrared monitoring cameras and other equipment, there are two technical problems:

[0007] 1. How to prevent someone from using the horizontal arm of the monitoring pole as a climbing support point to climb over the physical fence?

[0008] 2. Since the only way to enter and exit the flight area is through the security checkpoint, and it is prohibited to climb over the physical fence without security check, how can the equipment installed outside the physical fence, which is close at hand, be maintained in a short time?

[0009] Therefore, it is necessary to design a tiltable airport perimeter monitoring device to solve the above technical problems. Summary of the invention

[0010] The purpose of the present invention is to provide a tiltable airport perimeter monitoring device, which extends the environmental monitoring device to the physical perimeter of the airport for installation, thereby solving the technical problems of accurately monitoring the environmental dynamics around the physical perimeter and reducing the false alarm rate of the intrusion alarm system; changing the configuration of the existing perimeter security control box and its transmission method with the front-end equipment, extending the transmission distance, optimizing the system structure, and saving materials and costs; solving the technical problems of maintaining the equipment installed on the cross arm of the vertical pole outside the physical perimeter in the flight area and preventing someone from using the cross arm of the vertical pole as a climbing support point to climb over the physical perimeter, and facilitating use.
