Problems solved by technology
[0004] In the prior art, the energy storage capacitor needs to be able to maintain the entire communication device to work for a certain period of time after the power input port is powered off and a power-off alarm signal is generated. Therefore, the capacity of the energy storage capacitor is large, resulting in high equipment cost, poor reliability, and power failure. The module is bulky, and it is difficult for devices using DC power to upload power-down alarm information

[0037] Taking the RRU device as an example, in the new RRU device specification, the RRU power-down alarm is a necessary basic function. In the current RRU power-off alarm, the power module in the RRU detects the external power supply. When the external power supply drops to a certain voltage and maintains it for a certain period of time, a power-off alarm signal is generated and sent to the main board. The external interface FPGA (Field Programmable Gate Array, Field Programmable Gate Array) in the motherboard uploads the alarm information to the BBU (BandwidthBasedUnit, bandwidth-based unit) through the IR (Interface between the RRU and the BBU, interface between the radio remote unit and the baseband processing unit), and then the BBU Send to OMC (Operation&MaintenanceCenter, operation and maintenance center). After the power input port of the RRU is powered off and a power-down alarm signal is generated, the RRU needs to maintain a working time of 5ms to report the power-d...

The embodiment of the invention provides communication equipment and a power failure alarm method thereof for reducing the capacity of an energy storage capacitor required for power failure alarm information by the equipment. The equipment comprises a power module, a power conversion module, a functional module, a voltage detection alarm module and a power failure alarm processing module, wherein the power module is used for converting a power voltage into a main working voltage of the equipment; the power conversion module is connected with the power module and used for converting the main working voltage into a conversion voltage lower than the main working voltage; the functional module is connected with the power module and works under the drive of the main working voltage; the voltage detection alarm module is connected with the power module and the power failure alarm processing module and used for sending the power failure alarm information to the power failure alarm processing module when power fails; and the power failure alarm processing module is connected with the power conversion module and the functional module and used for working under the drive of the conversion voltage, turning off the functional module when the power failure alarm information is received and reporting the power failure alarm information.
Description
technical field [0001] The invention relates to the communication field, in particular to a communication device and a power-down alarm method thereof. Background technique [0002] When managing communication equipment, because the communication equipment may be placed outdoors or far away from the base station management room, the working environment is harsh, and it is easy to lose power. Therefore, it is necessary to know whether the communication equipment is unavailable due to external power failure or damage. At this time The power failure warning information of the communication equipment is very important. [0003] The power failure alarm method in the prior art is to detect the external power supply by the power module. When the external power supply drops to a certain voltage and maintains it for a certain period of time, a power failure alarm signal is generated and sent to the main board. The main board uploads the alarm information through the external interfac...
