Multi-parameter controller

Abstract

The invention discloses a multi-parameter controller, belonging to the technical field of controllers. According to the invention, the internal temperature of a controller is detected in real time through a temperature detection device, and a detected value is compared with a maximum temperature threshold value through a threshold value judgment device; when the temperature in a shell exceeds themaximum temperature threshold value, the threshold value judgment device sends an overtemperature signal to a motor and an exhaust fan, the motor responds to the overtemperature signal to rotate a gear, the gear rotates to drive a rack and a covering plate to linearly slide so as to allow a heat dissipation port to be in an open state, and meanwhile, the exhaust fan responds to the overtemperaturesignal to exhaust air in the shell; and the exhaust fan exhausts air from the heat dissipation port, so heat in the shell is dissipated outwards through the exhaust fan, the temperature in the shellis reduced, and the whole multi-parameter controller has the advantage of automatic cooling when the temperature in the multi-parameter controller is too high.

Description

technical field [0001] The invention relates to the technical field of controllers, in particular to a multi-parameter controller. Background technique [0002] In recent years, in the process of chemical production, the mutual influence between equipment is increasing significantly, so one operating variable will affect many control variables, and one control variable can also dominate the system affected by many operating variables, as a multi-parameter system. In the control process, if you want to eliminate the influence in the control process, you must control many parameters together at the same time. This control method is multi-parameter control. [0003] The Chinese patent with the publication number CN110888372A discloses a multi-parameter adaptive burner controller, including a burner controller body, a first movable splint, a spur rack, a first rotating gear, a connecting rotating rod, a second movable splint, Anti-slip pads, sponge pads, slide rods, slide rails...

AI Technical Summary

Problems solved by technology

[0004] Because there are a large number of electronic components in the controller, these electronic components will emit a lot of heat when they work for a long time. The heat accumulated in the controller will easily affect the normal operation of the electronic components, and even damage the electronic components, affecting the normal use of the components. It also shortens the service life of the controller
