Method for recovering equipment state after low voltage rise, main control signal board and system

Abstract

The invention relates to a method for recovering equipment state after low voltage rise, a main control signal board and a system. The method comprises the following steps: when a main control single board receives an under-voltage alarm signal reported by a power supply single board, detecting the operating state of a service single board; when abnormal operation of the service single board is detected and the under-voltage alarm signal reported by the power supply single board is received, sending a reset instruction to the service single board, so that the service single board returns to the normal state. On the basis that communication equipment has the characteristics of external enabling reset, with the low-voltage detecting result of the power supply single board, when the machine room power supply is abnormal, the power supply single board reports the under-voltage alarm signal, the main control single board detects the operating state of the service single board; when the service single board operates abnormally, and the power supply single board reports the under-voltage alarm disappearance signal, the main control single board sends the reset instruction to the service single board, so that the service single board in the abnormal state returns to the normal state, thereby protecting the normal operation of the equipment-carried service to the maximum extent and reducing the investment cost of a user.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method for recovering a device state after a low voltage rises, a main control single board and a system. Background technique [0002] At present, in the computer room of the communication system, to ensure the stable operation of the equipment, the computer room generally has power protection, usually equipped with a UPS battery as the protection power supply, so that when the working power supply fails, the power system can immediately switch to the battery protection power supply to ensure that the equipment normal power supply. However, since the battery cannot provide constant power output for a long time, its output voltage will gradually decrease as the power supply time continues, which will bring hidden dangers to the normal operation of the equipment. [0003] For the scenario where the device is powered by the battery and then switched back to the nor...

[0005] However, the above processing method needs to replace the power supply system of the computer room, which increases the user cost

In addition, since all equipment in the computer room needs to be taken into account, this method needs to set the safest voltage threshold, which makes some devices that can tolerate a voltage lower than the threshold also be powered off under the corresponding external voltage, which brings more trouble to the business. big impact
