Equipment limit intelligent control safety protecting system

Abstract

The system includes following circuits: control, limiting position, signaling conversion, self-checking circuit of limiting position, singlechip process, fault supervisory and fault display. The limiting position circuit includes an induction block setup. Receiving signal form the induction block, the limiting position circuit inputs the signal to the conversion circuit. The conversion circuit outputs signal to the self-checking circuit and the singlechip proces circuit. The self-checking circuit detects limited state in real time and displays the state. Processing unit in the singlechip process circuit outputs signal to the connected device control circuit to control on/off the circuit. The fault supervisory circuit inputs the signal sampled from the device into the singlechip. The processing unit for status analysis compares sampled value to technical parameters, and sends signal to the device control circuit and display circuit so as to complete closed loop control and display.

Description

technical field [0001] The invention relates to a safety protection system, in particular to an intelligent control safety protection system for limit protection of industrial equipment. Background technique [0002] The reliable and safe operation of industrial equipment, especially large-scale key equipment, is a long-term research topic in the field of fault diagnosis. Equipment failures are divided into two types: lifetime failures and sporadic failures. Uniform wear occurs when the equipment is operated under the allowable working conditions. When the wear exceeds the specified value, a life-time failure will occur. The time of this failure can usually be predicted, and its ability can be restored through regular replacement, repair, and transformation. Faults caused by changes in equipment working conditions are called sporadic faults. The time of sporadic failure is random and irregular, but it often starts from the abnormal working conditions of the equipment, so t...

Problems solved by technology

Although it can play a role in safety protection, due to the simple function and the structural defects of these two types of limit switches, it cannot fundamentally solve the sudden problem of occasional faults in the operation of the equipment. The failure of protection will cause damage to the equipment itself and the scrapping of the product, which will bring chain economic losses. When used in special equipment, there will always be hidden dangers of vicious accidents, threatening the life safety of equipment operators and surrounding people at any time.
