Problems solved by technology

[0003] The TCASII airborne collision avoidance system itself has many functions, and the system composition is extremely complex, including the airborne anti-collision equipment transceiver host, S-mode transponder, antenna switch, directional antenna, omnidirectional antenna, and supporting high-frequency and low-frequency cables, etc. A series of hardware equipment, which also includes various software and hardware systems, any part of which has a problem will have different degrees of impact on the TCASII airborne collision avoidance system, and these effects may appear in intermittent failures or hardware failures under various complex conditions. Fault, once the equipment fails, how to quickly locate and shorten the maintenance time will directly affect the use of TCASII airborne collision avoidance system users
[0004] The current TCASII airborne collision avoidance system has few and unsystematic monitoring items for itself, and cannot quickly and accurately locate faults. It lacks a complete and systematic TCASII airborne collision avoidance system hardware detection technology solution and software detection technology solution. Inspection and configuration management solutions cannot meet the requirements of modern integrated avionics systems

specific Embodiment 1

[0047] In this specific embodiment, aiming at the power supply self-check subsystem, a power supply self-check circuit and a power conversion circuit are designed, and the power supply self-check acquisition module of the TCASII airborne collision avoidance system is composed of FPGA and A / D sampling circuits, etc., and the self-check The acquisition module collects self-inspection data and reports it to the TCASII airborne collision avoidance system, and the TCASII airborne anti-collision system performs self-inspection of the power module according to the determined power self-inspection threshold. Its specific implementation process is:

[0048] The power supply self-inspection subsystem adopts the periodic self-inspection method to carry out the self-inspection of the power supply module. Each time, the power supply voltage of the power supply module is detected one by one, and the voltage value converted from the voltage value to a fixed range is obtained from the power su...

specific Embodiment 2

[0053] On the basis of specific embodiment 1, the monitoring task reads the task status of all TCASII airborne collision avoidance systems, monitors the task status, and detects whether there is a task abnormality or missing task. If there is a task abnormality or task missing, the monitoring task deletes the abnormal task Or recreate the missing task, for the abnormal task, initialize the system variables involved in the abnormal task, recreate the task, record the abnormal time of the task and the abnormal or missing event of the task to the task monitoring log. For the monitoring of the monitoring task itself, a software watchdog is designed to monitor the monitoring task and detect whether there is a task exception or missing task. If there is a task abnormality or task missing, delete the abnormal task or recreate the missing task. Recreate the task, record the abnormal time of the task and the abnormal or missing event of the task to the task monitoring log.

specific Embodiment 3

[0057] On the basis of specific embodiment 1 or 2, this function is mainly used for ground inspection and cannot be used in the air. The device is on the ground, that is, the wheel load and landing gear signals are on the ground, indicating that the TCASII airborne collision avoidance system can perform extended self-inspection. In this specific embodiment, press the front self-inspection button of the TCASII airborne collision avoidance system and keep In the down state for more than 2 seconds, the extended self-test function of the TCASII airborne collision avoidance system will be triggered.

[0058] In this specific embodiment, the extended self-inspection test module detects the wheel load signal, the landing gear signal and the front panel self-check button signal. When the state is down, the S-mode transponder or the transceiver host of the TCASII airborne collision avoidance system enters their respective extended self-inspection state machines. , the test result will...

Abstract

The invention provides an airborne collision avoidance system central maintenance system and maintenance method. The central maintenance system includes the following subsystems: a power supply self-checking subsystem, a task monitoring subsystem, a comprehensive self-checking subsystem, a starting self-checking subsystem, and an expansion self-checking subsystem. The comprehensive self-checking subsystem collects all the fault original information reported by the other subsystems of the airborne collision avoidance system and processes the faults comprehensively, and then stores the processed results and reports the results to an integrated avionics system. The integrated avionics system can obtain the self-checking results or the related information of the airborne collision avoidance system by starting the self-checking subsystems. The task monitoring subsystem monitors the task states of the airborne collision avoidance system in real time, monitors the online recovery in real time, and generates a monitoring log. The expansion self-checking subsystem enables the airborne collision avoidance system to realize human-computer interaction, and displays the LRU self-checking result through indicators.

Description

technical field [0001] The invention relates to a central maintenance system and a maintenance method of an airborne anti-collision system, in particular to a central maintenance system and a maintenance method of an airborne anti-collision system suitable for an integrated airborne anti-collision system based on TCASII. Background technique [0002] TCASII is an integrated airborne collision avoidance system, which is mainly used to provide air safety separation guarantee for aircraft to achieve the purpose of collision avoidance. By inquiring, receiving, and processing the response signals of other aircraft's transponders, it monitors other aircraft around, and calculates the flight trend of other aircraft within the monitoring range relative to its own aircraft, and gives traffic warning and decisive warning suggestions. [0003] The TCASII airborne collision avoidance system itself has many functions, and the system composition is extremely complex, including the airborn...
