An overheat protection system, method and device for electronic equipment

Abstract

The invention discloses an overheat protection system, method and device for electronic equipment. The overheat protection system is connected to a power switch of the electronic equipment, and includes a temperature acquisition module, a temperature detection module, a control module and a display module. The temperature acquisition module is used to collect the current working temperature of the electronic equipment, and output the working temperature to the temperature detection module, and the temperature detection module is used to output the corresponding detection signal to the control module according to the working temperature, and the control module It is used to judge the size of the working temperature according to the detection signal, and output temperature data to the display module when the working temperature is greater than the first temperature threshold; output a control signal to the power switch to control its shutdown when the working temperature is greater than the second temperature threshold On; the display module is used to display temperature data; the first temperature threshold is smaller than the second temperature threshold, thereby realizing real-time monitoring of the working temperature of the electronic device and avoiding damage to the electronic device.

Description

technical field [0001] The invention relates to the field of electric thermal protection, in particular to an overheat protection system, method and device for electronic equipment. Background technique [0002] With the increasing number of electronic devices and the diversity of functions, the functions of the corresponding electronic devices are also becoming more and more complex, and the amount of data processed by them is also increasing, which in turn leads to an increase in the heat of electronic devices. If the electronic The heat dissipation of the equipment is abnormal or does not achieve the desired effect. Correspondingly, the heat of the electronic device will cause damage to the electronic equipment; based on this, each electronic equipment needs to be set for temperature protection, but the temperature protection in the existing electronic equipment is only when the temperature exceeds When the set value is set, the circuit is disconnected; when the temperatu...

[0002] With the increasing number of electronic devices and the diversity of functions, the functions of the corresponding electronic devices are also becoming more and more complex, and the amount of data processed by them is also increasing, which in turn leads to an increase in the heat of electronic devices. If the electronic The heat dissipation of the equipment is abnormal or does not achieve the desired effect. Correspondingly, the heat of the electronic device will cause damage to the electronic equipment; based on this, each electronic equipment needs to be set for temperature protection, but the temperature protection in the existing electronic equipment is only when the temperature exceeds When the set value is set, the circuit is disconnected; when the temperature is lower than the set value, the circuit is turned on and restored, but it cannot achieve low temperature regulation, nor can it monitor multiple temperature zones, and the corresponding protection device is not universal
