Low-temperature single chip microcomputer starting and working method and low-temperature running single chip microcomputer system for achieving method

Abstract

The invention relates to a low-temperature running single chip microcomputer system and belongs to the field of electronic technological application. The problems that an existing single chip microcomputer cannot be started in a low-temperature environment and cannot stably accurately work in the low-temperature environment are solved. The method comprises the steps of adopting a short time heating lamp to instantaneously heat the working environment of the single chip microcomputer when the single chip microcomputer is started; monitoring the temperature of the working environment of the single chip microcomputer in the working process of the single chip microcomputer, and controlling the heating lamp to control the temperature of the working environment of the single chip microcomputer according to the temperature. A capacitor C in the low-temperature running single chip microcomputer system, a short time heating lamp J1 and a current-limiting and discharge resistor R1 are in series connection between an anode and a cathode of a direct current power supply of the single chip microcomputer, the temperature signal output end of a digital temperature sensor W is connected with the temperature collecting signal input end of the single chip microcomputer, and the single chip microcomputer controls a controllable heating lamp J2 to be turned on or turned off through a driving field-effect tube T. According to the low-temperature single chip microcomputer starting and working method, low-temperature starting and running of the single chip microcomputer system can be guaranteed.

Description

technical field [0001] The invention belongs to the application field of electronic technology. Background technique [0002] 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 cannot star...
