Embodiment Construction

[0029] The specific implementation of the method of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Please also see figure 1 , figure 2 with image 3 . The aircraft electromechanical system mainly includes a management computer, n power distribution devices, and a bus, among which, the management computer and n power distribution devices perform information interaction through the bus.

[0031] In this embodiment, there are 30 single power distribution channels inside each power distribution device, and the total number of single power distribution channels in the system is 30×n. If the value of n is 10, there are 10 power distribution devices and 300 single power distribution channels in the system. Each power distribution channel has at least 6 states: on, off, overload, short circuit, fault and unknown. Using BCD code to encode the above 6 states needs to occupy 4 binary bits.

[0032] When using the tradi...

Abstract

The invention belongs to airborne data processing technology, in particular to a method for processing state data of a power distribution channel of an aircraft electromechanical system. In the method for processing the state data of the power distribution channel of the aircraft electromechanical system of the present invention, after the power distribution device is powered on and started, the state of all the power distribution channels of itself is periodically obtained, and a power distribution channel state message is formed, and the management computer retrieves the state of the power distribution channel through the bus message, select and use the status of the power distribution channel in the normal state, and query the status of the power distribution channel in the abnormal state. In the present invention, the content of the normal state power distribution channel state message and the content of the abnormal state power distribution channel state message of the power distribution device are respectively inquired and obtained by the management computer, and the state of the power distribution channel is reasonably configured without reducing the amount of effective data. , reducing the data volume of the power distribution channel state on the electromechanical system bus, and reducing the bus load rate.

Description

technical field [0001] The invention belongs to airborne data processing technology, in particular to a method for processing state data of a power distribution channel of an aircraft electromechanical system. Background technique [0002] Aircraft electromechanical systems usually include management computers, multiple power distribution devices, and electrical equipment. The power distribution device is usually a power distribution device with a computer module. There are multiple single-channel power distribution channels inside the power distribution device. Electric channel state. Distribution channel status data includes information such as on, off, overload, short circuit, fault, and unknown. In the aircraft electromechanical system, the management computer performs data interaction with the power distribution device through the bus. [0003] The existing common data transmission method is: in the system, each power distribution device codes the possible channel st...
