Description

Technical Field

[0001] The present invention belongs to the technical field of production of airport navigation station control equipment, and in particular relates to a centralized control device for an airport navigation station. Background Art

[0002] An airport navigation station is a ground station that determines the position of an aircraft and guides it along a predetermined route. It uses the propagation characteristics of radio waves to measure flight navigation parameters (direction, distance, and speed), calculate deviations from the prescribed route, and then the pilot or autopilot controls the aircraft to eliminate these deviations and maintain the correct route. The centralized control device for an airport navigation station is a system for monitoring, remotely controlling, and maintaining airport equipment. It primarily implements centralized control, maintenance, and monitoring of navigation equipment, remotely monitors environmental information such as temperature, humidity, smoke, infrared, and video camera information within the station where the equipment is located in real time, and remotely manages the station's power supply, air conditioning, and other equipment, ultimately enabling the unmanned operation of the airport navigation station.

[0003] The core electronic device of an airport navigation station centralized control device is the signal processor. To better protect the signal processor and prevent it from being damaged by rainwater intrusion, traditional airport navigation station centralized control devices generally have a mechanical protection structure around the signal processor. A common mechanical protection structure is a fence. For example, the utility model patent with announcement number "CN220476108U" discloses an airport navigation station centralized control device. The fence of this device protects the signal processor. The cover plate is easy to disassemble through the combination of a slot and a lever, facilitating subsequent maintenance and adjustment of the equipment. The drainage column can guide rainwater into the sump, and then discharge the rainwater through the drain trough, making the device waterproof and collision-resistant.

[0004] However, during the long-term use of the above-mentioned traditional airport navigation station centralized control device, the fence cannot block tiny particles such as sand and dust. Sand and dust can enter the fence through the gaps in the fence and adhere to the signal processor, affecting its heat dissipation and normal operation, thereby reducing its signal transmission efficiency; at the same time, during high temperatures in summer, the air circulation inside the fence is relatively poor, and heat is easily accumulated, causing the internal temperature of the signal processor to be too high, accelerating the aging of electronic components, and even causing component failure.
