ARM-based temperature control system and temperature control method

Abstract

The invention relates to a temperature control system, and in particular relates to a temperature control system and a temperature control method based on ARM. The problems that an existing temperature control system is single in function, single in problem processing and low in efficiency are solved. The system comprises an ARM processor, a power module, a fluorescent optical fiber temperature collection module, keys, a liquid crystal screen, a relay module, an RS232 interface, an RS485 interface and an Ethernet interface. The ARM processor can control a plurality of operations such as 4-20 mA signal output, RS485 communication output, Ethernet communication output, relay signal output, data storage, historical data copying and automatic application program updating. The temperature control system further provides LCD liquid crystal display and key setting. The man-machine interaction function is achieved, and operation is easy. The requirement of a user for multifunctional intellectualization of the temperature measurement system is met. The system can be applied to high-voltage, large-current, strong-magnetic-field or more complex environments.

Description

technical field [0001] The invention relates to a temperature control system, in particular to an ARM-based temperature control system and a temperature control method. Background technique [0002] With the development of society, temperature control systems are widely used in various important workplaces such as power grid industry, energy industry, and railway industry. Existing temperature control systems based on single-chip microcontrollers have single functions, single processing problems, and low efficiency. Under high voltage, high current, strong magnetic field or more complex environments, they can no longer meet the user's personalized temperature control system. , complexity and other usage requirements. Contents of the invention [0003] In order to overcome the problem of single function, single processing problem and low efficiency of the existing temperature control system, the present invention provides an ARM-based temperature control system and tempera...
