Automatic restart method, system and device for power failure

Abstract

The invention provides an automatic restart method for power failure, which comprises the following steps of: sending a restart command for power failure to remote equipment by a master station; generating a restart level of a master power supply for power failure by the remote equipment according to the restart command for power failure, and sending the restart level of a master power supply for power failure to a power panel by the remote equipment; and after receiving the restart level of the master power supply for power failure, the initiating power failure of the master power supply and restarting the master power supply in scheduled time by the power panel. The invention realizes remote restart control after power failure without climbing or manually starting or shutting a station, thereby reducing operating time, maintenance time and cost by realizing self recovery of remote terminals after partial software faults.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for automatic power-off restart. Background technique [0002] 3G mobile communication system base stations mostly adopt the form of BBU (indoor baseband processing unit) + RRU (radio remote unit). Usually, the RRU is installed on the top of the tower, or on a place with a very high roof. It is very difficult to perform power-off recovery operation on site. However, when some non-hardware failures of the remote device cause self-recovery, such as software out of control, transmission link loss of lock, abnormal channel connection, and remote control failure, etc., such non-hardware failures are not hardware damage, so there is no need to In the event of a failure to replace a device, it is only necessary to take appropriate measures to restore the system to normal operation again. [0003] At present, the methods for implementing recov...

[0002] 3G mobile communication system base stations mostly adopt the form of BBU (indoor baseband processing unit) + RRU (radio remote unit). Usually, the RRU is installed on the top of the tower, or on a place with a very high roof. recovery failure, it is very difficult to perform power-down recovery operations on site

[0008] 1. Using soft reset, the reset is not complete, and some problems cannot be solved: including: the firmware does not reset, and the problem cannot be solved; the reset initiator device has a software failure, and it has been impossible to issue a reset command; some devices have problems related to the power-on sequence can't solve

[0009] 2. Use hard reset: hard reset refers to reset through the button, and the reset is initiated by manually touching the button; the disadvantages of this method are: first, the reset is not complete, and the problems related to the power-on sequence cannot be solved; in addition, the RRU is used as an outdoor device , waterproof, high mechanical strength requirements, buttons cannot be exposed outside the box, and many installation locations are on the top of the tower, this operation is difficult to achieve

But as mentioned above, the particularity of the installation location of the RRU outdoor equipment determines the infeasibility of this operation, and this operation and maintenance method is not in line with the development of modern communications
