Remote-operated one-chip microcomputer system for executing heating control

Abstract

The invention provides a remote-operated one-chip microcomputer system for executing heating control, and belongs to the field of electronic technology application. The invention solves problems in existing one-chip microcomputer systems which work cooperatively in a distributed way in environments with severe temperature that each one-chip microcomputer system is additionally provided with a temperature detection and control circuit so that a circuit becomes complicated and original functions of each one-chip microcomputer system are affected. The one-chip microcomputer system is composed of an operating one-chip microcomputer unit and multiple heating one-chip microcomputer units. The operating one-chip microcomputer unit acquires actual temperature information of each heating one-chip microcomputer unit in turn via a CAN bus. The operating one-chip microcomputer unit sends a heating start or stop signal to the corresponding heating one-chip microcomputer unit according to actual temperature of each heating one-chip microcomputer unit and presupposed minimum temperature and maximum temperature. Each heating one-chip microcomputer unit starts or stops heating according to the received heating start or stop signal. The system is applicable to heating control of a multipoint system in an environment with a high temperature difference.

Description

[0001] Application field [0002] The invention belongs to the application field of electronic technology. technical background [0003] In electronic technology, single-chip microcomputer is an important microprocessor chip. Single-chip microcomputer system is a widely used and powerful digital electronic system. The operating temperature of the single-chip microcomputer is generally between minus 20 degrees Celsius and minus 60 degrees Celsius. Within this temperature range, the single-chip microcomputer can work normally, but after exceeding this temperature range, the single-chip microcomputer cannot work normally, and then affects the work of the entire single-chip microcomputer control system. Due to the limitation of this parameter, the application of single-chip microcomputer system in cold regions is limited. In cold areas, due to the low ambient temperature, there are often problems that some equipment or instruments using single-chip microcomputers as the core ca...
