Description

Technical Field

[0001] The invention belongs to the technical field of power distribution system control, and in particular relates to an aircraft position identification and position conflict processing system of a dual-controller aircraft. Background Art

[0002] In the field of aviation power distribution systems, with the substantial increase in onboard electrical equipment, the role of controller products in aircraft power distribution systems has become increasingly important. In order to expand the application scenarios of controller products with similar hardware configurations and reduce the waste of cycles and resources caused by repeated development, controller products with similar hardware configurations adopt an interchangeable design, and use the position identification method to determine their own equipment position number to realize product-related functions.

[0003] CN101916195A Interchangeable software configuration control method for multiple electronic devices and CN 116047157 A Unified high-voltage DC intelligent contactor and method based on isolated current detection perform machine position identification through discrete quantity acquisition. CN111258388 A A special intelligent main control box for climbing frames and CN 112504710 A A vibration state intelligent monitoring system and method perform machine position identification only by receiving the machine position identification bus signal of the host computer. The signal source, machine position identification method and machine position conflict processing of machine position identification are quite different from the content of this patent; CN 108614698 A A partition loading method suitable for airborne redundancy computers focuses on the software partition processing after machine position identification is obtained, and the source of the machine position signal is not clear. In the absence of a host computer communication machine position number, controller product machine position identification generally only uses discrete machine position identification. If the controller machine position identification is incorrect, it may cause the controller to incorrectly control the contactor in the distribution network according to the wrong machine position number, which may cause abnormal power supply conversion in the distribution network, and then cause power outages on some buses; in addition, incorrect controller machine position identification may also cause AC power supplies to be connected in parallel, resulting in serious consequences.

In the absence of a host computer communication position number, the system collects the discrete aircraft position number provided by the power distribution device and analyzes the bus aircraft position number provided by the opposite controller through the dual redundant bus between the two controllers to comprehensively judge its own aircraft position number.

[0032] Example based on Figure 1 The typical architecture of the power distribution network forms a functional activity diagram of the station identification function by adding station identification and station conflict handling methods, such as Figure 2 As shown, the main steps include: Step 1: After the two controllers are powered on and initialized, the discrete machine position numbers provided by the power distribution device are collected; Step 2: The two controllers receive the bus machine number provided by the opposite controller via the dual-redundancy bus between the two controllers; Step 3: The two controllers identify the discrete machine position number on the local side and the bus machine position number on the opposite side according to the logic of Table 1 and Table 2; The determination of the bus machine number on this side is shown in Table 2: Table 1 Determination of the discrete machine position number on this side

[0033] If the first channel of the discrete machine position signal is grounded and the second channel is open, the identified discrete machine position number on this side is the left controller; If the first discrete position signal is open and the second discrete position signal is grounded, the identified discrete position number on this side is the right controller; If the first and second discrete machine position signals are both open or grounded, the identified discrete machine position number on this side is invalid.

[0035] If only one of the bus machine numbers provided by bus 7 or bus 8 is valid, the low bit is 1 and the high bit is 0, and the other one has no received data, then the identified bus machine number of the opposite side is the left controller; If only one of the bus machine numbers provided by bus 7 or bus 8 is valid, the low bit is 0 and the high bit is 1, and the other one has no received data, then the identified bus machine number of the opposite side is the right controller; If the bus machine position numbers provided by bus 7 and bus 8 are both invalid, the identified opposite bus machine position number is invalid.

[0036] Step 4: The two controllers comprehensively judge their own machine position numbers according to the following logic.

[0037] Table 3 Comprehensive judgment of the aircraft number results

[0038] like Figure 2 As shown, the two controllers first determine in turn whether the discrete machine number on the local side is the left controller or the right controller; If the discrete machine position number on this side is the left controller, then further determine whether the bus machine position number on the opposite side is the right controller, whether it is the left controller, and whether there is a conflict. According to Table 3, the result of the own machine position number is determined to be left controller / right controller / conflict.

[0039] If the discrete machine position number on this side is not the left controller but the right controller, then further determine whether the bus machine position number on the opposite side is the left controller, the right controller, and whether there is a conflict. According to Table 3, the result of the machine position number is determined to be left controller / right controller / conflict.

[0040] If the discrete machine position number on this side is neither the left controller nor the right controller, then further determine whether the bus machine position number on the opposite side is the left controller, the right controller, and whether there is a conflict. According to Table 3, the result of the machine position number is determined to be left controller / right controller / conflict / invalid.

[0041] Step 5: After the two controllers comprehensively judge their own machine position numbers, they should do the following: If the aircraft position number is the left controller or the right controller, start to perform on-board work; after entering the on-board work, keep the aircraft position number unchanged.

[0042] If the machine number itself conflicts, the initial state of discrete output will be maintained until the product is powered off.

[0043] If the machine number itself is invalid, the initial state of discrete output will be maintained until the product is powered off.

[0044] After completing the machine position identification and processing, the left controller and the right controller store the machine position number, and control the power distribution device on this side according to their own control logic, and collaboratively realize the power supply conversion of the distribution network.
