Problems solved by technology

[0003] In the existing solution, although the over-temperature protection of the service board and the SFU can be realized through the main control board, the main control board itself has no over-temperature protection function, and the main control board will be damaged if it is overheated for a long time. Even cause the equipment to catch fire, thereby affecting the business processing of the entire equipment

Abstract

The embodiment of the invention provides a main control board over-temperature protection method and communication equipment and relates to the heat dissipation technology field. The method comprisesthe following steps of acquiring the temperature information of the main control board of communication equipment; when the temperature information of the main control board exceeds a preset first over-temperature turn-off threshold, if the communication equipment has no standby board, carrying out power off processing by the main control board; and if the communication equipment has the standby board, after the standby board and the main control board carry out main / standby switching, carrying out power off processing by the main control board. A problem that the main control board is under an over-temperature state for a long time so that the equipment is on fire is avoided, the over-temperature protection of the main control board is realized, the service life of the main control boardis prolonged to some extent and user investment cost is saved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a method for over-temperature protection of a main control board and a communication device. Background technique [0002] With the gradual increase of power consumption of communication equipment, over-temperature protection of communication equipment is particularly important. When a communication device is running, if a fan fails, the temperature of each board inside the device will rise. If the fan fails for a long time, chips on the board may be damaged, and in extreme cases, the device may even catch fire. To reduce the impact of fan failures on communication devices, the main control board usually monitors the temperatures of service boards and SFUs at regular intervals, and controls the service boards or SFUs to power off when the service boards or SFUs are overheated. [0003] In the existing solution, although the over-temperature protection of the service boa...
