Ruggedized machine multi-machine system based on task monitoring and redundancy design method

Abstract

The invention relates to the technical field of communication control, in particular to a ruggedized machine multi-machine system based on task monitoring and a redundancy design method. The reinforced machine multi-machine system comprises a control management unit and a plurality of reinforced machines which are connected with each other, wherein the control management unit comprises a serial port server module and an alarm display module which are connected with each other; the alarm display module is connected with each reinforcing machine through two groups of dual-redundancy CAN buses, the state bus is used as a running state notification and control decision bus to construct a response mechanism between equipment, and each reinforcing machine sends heartbeat information and fault information to the alarm display module of the control management unit through the two groups of dual-redundancy CAN buses. The control management unit switches the external interface of the fault reinforcing machine to the normal working reinforcing machine, multi-machine hot standby is realized through strategies such as state reporting, fault inspection and control decision, the task implementation reliability is high, the fault can be quickly removed, and the detectability and the maintainability of the system are improved.

Description

technical field [0001] The invention relates to the technical field of communication control, in particular to a task monitoring-based multi-machine system and a redundancy design method for a reinforced machine. Background technique [0002] In the field of communication control, the reinforcement machine, as the core control equipment, is responsible for the communication with the vehicle-mounted equipment, the command and control system, and the detection vehicle, and controls the output of different signals according to the decomposed instructions, and detects the input signal. The reliability of the computer is required to be high. Once a problem occurs and the task cannot be executed, the redundancy design method based on the task monitoring and reinforcement machine can ensure the highly reliable execution of the system task. [0003] However, in the prior art, the communication control of the on-board equipment, the command and control system, and the detection vehic...
