PLC-based remote temperature controlSystem design: temperature control system design paper

so that the quality of the product can be greatly improved. Therefore, intelligent temperature control technology is being widely applied. This temperature design adopts the now popular AT89C51 single-chip microcomputer as the controller, uses the PID control method, and is equipped with other circuits to control the water temperature of the water heater.

The precision temperature control system based on single-chip microcomputer digital PID control designed in this paper has achieved good control effect in practical application, and the temperature control accuracy reaches ±0.1℃.

This paper designs a temperature measurement and control device based on MSP430 single-chip microcomputer, which can measure the ambient temperature, and can give the adjustment amount according to the given temperature value, control the actuator, and achieve the purpose of regulating the ambient temperature.1 Overall scheme design Single-chip microcomputer temperature control system takes MSP430 single-chip microcomputer as the control core.

In response to the call of innovative enterprises of electromechanical companies and automation branches, I am now developing a "digital analog signal generator" and "heat treatment temperature control system" based on single-chip microcomputers. The former should be given the debugging of the on-site instrument and the PLC analog signal, and the latter will be applied to the heat treatment of on-site machinery and equipment installation.

The automated measurement and control of the industrial production process almost mainly relies on various sensors to detect and control various parameters in the production process, so that the equipment and system can operate normally in the best state, so as to ensure the high efficiency and high quality of production. 1 Selection of temperature sensor Scheme 1: Adopt thermal resistance temperature sensor.

Elevator Control Technology Paper (2)

1. In electricity In the troubleshooting of ladder faults, the control system can quickly analyze the types of faults and improve the stability of the elevator by entering fault data. Intelligent control. Intelligent control is the second largest type of intelligent technology in the elevator control system.It mainly includes two major components: "processing unit" and "system application". The first is the processing unit.
