Embodiment 1

[0025] When the thermocouple detects that the temperature of the circuit board is lower than -30°C and does not meet the start-up conditions, the PID controller controls the heating wire to start working to increase the temperature of the corresponding position of the circuit board. When the thermocouple detects that the temperature of the circuit board is higher than 0°C, the PID controller controls the heating wire to stop working, and the circuit board can start normally at this time. When the galvanic couple detects that the temperature of the circuit board is lower than -30°C, the heating circuit is restarted, and the cycle repeats.

Embodiment 2

[0027] When the thermocouple detects that the temperature of the circuit board is lower than -40°C and does not meet the start-up conditions, the PID controller controls the heating wire to start working to increase the temperature of the corresponding position of the circuit board. When the thermocouple detects that the temperature of the circuit board is higher than -15°C, the PID controller controls the heating wire to stop working, and the circuit board can start normally at this time. When the galvanic couple detects that the temperature of the circuit board is lower than -40°C, the heating circuit is restarted, and the cycle repeats.

Embodiment 3

[0029] When the thermocouple detects that the temperature of the circuit board is lower than -50°C and does not meet the start-up conditions, the PID controller controls the heating wire to start working to increase the temperature of the corresponding position of the circuit board. When the thermocouple detects that the temperature of the circuit board is higher than -25°C, the PID controller controls the heating wire to stop working, and the circuit board can start normally at this time. When the galvanic couple detects that the temperature of the circuit board is lower than -50°C, the heating circuit is restarted, and the cycle repeats.

Abstract

The invention specifically relates to a method for realizing low temperature starting of equipment in a circuit board. The method for realizing low temperature starting of equipment in a circuit board comprises adding a heating circuit near a chip having high requirement for temperature on the circuit board, wherein when the temperature of the circuit board is lower than a specific value and cannot satisfy the starting condition, the heating circuit starts working so that the temperature of the corresponding position of the circuit board starts to rise; when the temperature is greater than the specific value, the heating circuit stops working; when the temperature is lower than the rated value again, the heating circuit starts working again; and then the above process repeats. The method for realizing low temperature starting of equipment in a circuit board is simple in design and is convenient to use, and solves the problem that electronic equipment is difficult to start and is unable to start under lower temperature so that the equipment can start normally under the lower temperature environment and the reliability of electronic products can be improved under the lower temperature environment.

Description

technical field [0001] The invention relates to the technical field of circuit board start-up, in particular to a method for realizing low-temperature start-up of equipment in a circuit board. Background technique [0002] With the rapid development of electronic technology, its application fields are becoming more and more extensive. More and more electronic products appear in people's daily life and work, and become an indispensable part of national life. It can even be said that the long-term stable development of modern society is inseparable from the support of electronic technology. Electronic chips, especially integrated circuit chips, have a certain temperature range, and the device will not start after exceeding this temperature range. Therefore, the start-up of circuit boards in extreme environments is an urgent problem to be solved. [0003] Generally, the design of ordinary electronic products that are common in life generally does not have high requirements f...
