System Design for Temperature Control and Distribution Detection Based on 485 Communications

This paper introduces the temperature control and detection system under the monitoring of computer, which was applied SRS14A temperature controller and the K8511 thermal resistance acquisition module, based on the 485 communication for the exploration of trial-manufacture dry sintering of the heating chamber. The authors make a brief introduction about the communication of SRS14A temperature controller and the K8511 thermal resistance collection module, give the principle of the double timer timing cycle data acquisition, provide for the control program flow chart and related program code. Through the VB6.0 programming, the serial communication between the computer and the modules is realized. The temperature is collected and controlled. The centralized control is realized, and the operation and data processing is easy. Based on the idea of programming, this method can be used for the expansion of the similar principle module control.
