The invention relates to a flameproof explosion-proof control system, which comprises a large power strong electricity flameproof tank for insulating large power strong electricity, a small power weak electricity flameproof tank for insulating small power weak electricity and an explosion-proof operating column for operating and controlling the display portion, wherein the large power strong electricity flameproof tank, the small power weak electricity flameproof tank and the explosion-proof operating column are connected via cables, the small power weak electricity flameproof tank is provided with a programmable controller for processing collected signal, generating flameproof explosion-proof control signal according to the collected signal, and sending the control signal to the large power strong electricity flameproof tank to execute functional process. The programmable controller is respectively connected with the large power strong electricity flameproof tank and the explosion-proof operating column. The invention further relates to a flameproof explosion-proof control method. The invention uses a programmable controller to replace the intelligent control system which directly uses electric component and uses microcomputer as core, to improve operation reliability and versatility of the flameproof explosion-proof control system, with simple maintenance and production and low cost.
Description
technical field [0001] The invention relates to the field of explosion-proof and explosion-proof electrical equipment, in particular to a split-type explosion-proof and explosion-proof control system and method. Background technique [0002] At present, in industrial explosive hazardous places and chemical and dust polluted places, the demand for measuring instrument systems and electrical device systems is increasing. If explosion-proof electrical components are directly used to form an intelligent control system with a microcomputer as the core, the cost is high and some The components cannot meet the national standard with the current technical level, the versatility is low, and the reliability of the system operation is low. Therefore, there is no intelligent control system with microcomputer as the core that directly adopts explosion-proof electrical components, which cannot meet the needs of industrial explosive hazardous places and chemical and dust polluted places. ...
