Automatic power-off recovery method and device after base station fault

Abstract

The embodiment of the invention provides an automatic power-off recovery method and device after a base station fault. In the method, a programmable power supply device performs the periodic heartbeatinteraction with a base station, and it is considered that the base station has a fault of software death when the number of continuous loss times of the heartbeat of the base station is judged to exceed a preset threshold value, and a base station board card power-off instruction is instantly generated so as to enable all board cards of the base station to be electrically disconnected. After a preset time period, the board card of the base station is considered to complete the power-off operation, and at this moment, a base station board card power-on instruction is generated to enable the base station to restore the power-on start. Therefore, the method can timely find out the fault of the base station after the death of the software of the base station, and there is no need of manual positioning. Moreover, the method can achieve the automatic power-off and restart of the base station when there is a fault, so as to enable the base station to return to a normal state. The method reduces the adverse effect to maximum degree, saves time, is efficient, and effectively saves the manpower resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for automatically powering off and restoring after a base station fails. Background technique [0002] The structure of the base station BBU (Building Base band Unit, remote radio unit) is as follows: figure 1 As shown, the PSU (power supply module) supplies power to other boards in the base station, where SCTX represents the main control board, BPOX represents the baseband board, FC represents the fan, and EMA represents the environmental monitoring unit. figure 2 The network diagram of the base station is shown. After the base station is started, it will monitor the status of the board. If the status of the board is abnormal, that is, the base station is faulty, it will report an alarm to the management station OMC, and then the operation and maintenance personnel will handle it. Outfield base station faults can be divided into two categorie...

Problems solved by technology

However, after some tasks are abnormal, the reset command issued by the management station will not take effect, and the operation and maintenance personnel can only power on and off the station to restart

A simple operation needs to go through five cumbersome processes: placing an order to the operation and maintenance department→ dispatching an order by the operation and maintenance department→ going to the station by the operation and maintenance personnel→ powering off→ restarting. In urban areas, the problem-solving cycle is long, time-consuming and laborious
