Problems solved by technology

[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

Embodiment Construction

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0030] The main purpose of the present invention is that the master station sends a power-down restart command to the remote device, so that the remote device can be restarted, so that for some software failures, it can be fully reset before repairing on the station, thereby reducing the process of station positioning and the like In addition, even if the problem cannot be solved by restarting after power failure of the present invention, it can be judged that a hardware failure has occurred, thereby gaining time for repairing. In additi...

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...
