Constant-temperature control system

Abstract

The invention relates to the technical field of modern electronic application, in particular to a constant-temperature control system. The constant-temperature control system comprises a single chip microcomputer controller, a temperature acquisition circuit, a signal amplifying and conditioning circuit, an analog/digital conversion module, an LED display module, a function press key input module, a temperature control module, a communication module and a display module, wherein the LED display module, the function press key input module, the temperature control module, the communication module and the display module are connected with the single chip microcomputer controller respectively; the temperature acquisition circuit, the signal amplifying and conditioning circuit and the analog/digital conversion module are connected in sequence, and the analog/digital conversion module is connected with the single chip microcomputer controller; the single chip microcomputer controller is connected with a remote upper computer through the communication module. The constant-temperature control system which has high temperature change curve visibility and the remote controllability is very suitable for the industrial remote management requirements. The constant-temperature control system is low in cost and good in expansibility; the portability of the system is improved. Water temperature can be constantly controlled within the range of 40-90 DEG C, the control error is smaller than 0.5 DEG C, the static error is smaller than 0.2 DEG C, and the constant-temperature control system can be widely applied and moved in the industry.

Description

technical field [0001] The invention relates to the technical field of modern electronic applications, in particular to a constant temperature control system. Background technique [0002] In daily industrial production, constant temperature control is widely used. Fuzzy control technology uses uncertain fuzzy information to make decisions by imitating people's thinking methods to achieve the best control effect. At present, the temperature control system that can be purchased on the market can achieve low precision in temperature control, and the system The portability is not good, the control error and static error are relatively large, and the possibility of errors in the use process is relatively high, so the scalability is not enough, and it cannot meet the requirements in large-scale industrial production. Contents of the invention [0003] The invention aims to provide a constant temperature control system with good portability, high precision and small err...
