Problems solved by technology

[0003] Due to the high reliability of 1553B communication, at present, the software developed based on 1553B bus at home and abroad generally does not do fault handling, and the reliability of communication is improved by improving the reliability level of 1553B interface chip, but the reliability of 1553B interface chip The level cannot reach 100%, and the external interference cannot be completely shielded, so there is an urgent need for a 1553B bus communication fault handling method

Embodiment 1

[0070] The following takes the interface chip as Bu61580 as an example to illustrate the fault real-time monitoring and recovery processing methods of 1553B bus communication.

[0071] In this embodiment, the 1553B bus interface chip Bu61580 includes 4 configuration registers, and the following table 1 shows the initial values ​​of the 4 monitoring registers of Bu61580:

[0072] register name Register bits to check initial value Remark RT_Interrupt_Mask_Reg D15~D0 0x0001 / RT_Config_Reg1 D15~D1 0x8F80 D0 is the status bit RT_Config_Reg2 D15~D0 0x1012 / RT_Config_Reg3 D15~D0 0x8015 /

[0073] (1), judge whether the current value of the first configuration register RT_Interrupt_Mask_Reg in the 1553B bus interface chip is equal to 0x0001, the judgment result is unequal, the error state flag position of this configuration register is 1, and enters step (2);

[0074] (2), judge whether the current value of the second configu...

Abstract

The invention relates to a 1553B bus communication fault processing method. For a bus communication fault which cannot be automatically recovered due to abnormal work of a 1553B bus interface chip, by regular monitoring of a value of an important register of the 1553B bus interface chip, a working state of the chip is judged to realize detection of the fault; when the detected value is inconsistent with an initial value, pointer variables of the chip register and a 1553B bus command word stack are reinitialized to enter an expected working mode, so that fault recovery is realized, and the reliability and the interference resistance of the system are improved; by the ingenious design of fault detection flow, different processing modes are carried out on different faults of a configuration register in the 1553B bus interface chip; and therefore, the fault processing accuracy is improved, the fault processing efficiency is improved, and procedures and the time are saved.

Description

technical field [0001] The invention relates to a 1553B bus communication failure processing method, which is used to solve the failure problem when aerospace servo control software and an assembly upper computer perform 1553B communication, and belongs to the technical field of 1553B bus communication. Background technique [0002] 1553B bus communication technology is a highly reliable military communication method, which is widely used in aerospace servo control software. When the 1553B interface chip is abnormal, the 1553B communication is abnormal, and the upper computer of the assembly and the servo control software cannot communicate normally, thus affecting the servo. Control software reliability. Therefore, how to solve the problem of 1553B bus communication failure has become a key issue to improve the reliability of the servo controller software. [0003] Due to the high reliability of 1553B communication, at present, the software developed based on 1553B bus at ...
