Abstract

The invention discloses a nonporous electronic control security door fault-tolerant control system. The nonporous electronic control security door fault-tolerant control system adopts a dual fault-tolerant system structure, wherein a processing unit is formed by receiving control modules, data of the two control modules is from a signal received by a receiver, a manual control switch on a door can control the two modules, and the two modules can detect the state of a door switch; the two modules comprise one main module and a slave module; when the two modules receive a signal sent by a transmitter, the processing unit operates the control algorithm to obtain a result, the result of the main control module is only output to a control motor through a crossbar switch to control the door switch; when the main control module has a fault, the system can switch the slave module to the main module, the fault can be switched rapidly, no any task immigration is required, no data loss is caused during task relaying, the real-time performance of the system is ensured and the usability and the reliability of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of information control and relates to a fault-tolerant control system for a non-porous electronically controlled anti-theft door. Background technique [0002] High-reliability fault-tolerant technology involves software fault-tolerant and hardware fault-tolerant technology. The software fault-tolerant technology has made great progress. The software system has developed to this day. The scale and complexity of the software system are obvious to all, but the low reliability of the software is very worrying. Many people have begun to study software reliability theoretically, and have also proposed some algorithms. Judging from the needs and the results achieved, it will not be long before there will be a rudimentary fault-tolerant software design method, and some practical tools will be produced in the fault-tolerant design of application software. The fault-tolerant design method combining hardware fault-to...
