Specific embodiments of the invention are given below:
For RRU device, in new RRU device specification, the power fail warning of RRU is as a kind of necessary basic function.Present RRU power fail warning is to be detected external power source by the power module in RRU, when external power source produces power fail warning signal after dropping to certain voltage and keeping certain time, gives mainboard.External interface FPGA (FieldProgrammableGateArray in mainboard, field programmable gate array) this warning information is passed through IR (InterfacebetweentheRRUandtheBBU, the interface of Remote Radio Unit and baseband processing unit) interface is uploaded to BBU (BandwidthBasedUnit, unit based on bandwidth), OMC (Operation&MaintenanceCenter, operation maintenance center) is given again by BBU.RRU needs the working time maintaining 5ms to report power fail warning after power input port power down and generation power fail warning signal.
As shown in Figure 6, it is structure and the signal schematic representation of RUU provided by the invention.Described interface FPGA corresponds to described power fail warning processing module, and described power amplifier module corresponds to described functional module, and described power conversion module includes in mainboard power conversion 2 in power conversion 1 and mainboard, represents that main running voltage has carried out twice conversion.
When RRU normal operation, power module produces the running voltage that power amplifier and mainboard (include in processor, interface FPGA, voltage detecting warning circuit, mainboard in power conversion 1, mainboard power conversion 2) work is required, running voltage one tunnel powers for the grid voltage of power amplifier to power amplifier module, another road is converted to 5V bus power source by a power conversion 1 on mainboard, produced the various voltages needed for each chip of mainboard by 5V bus power source by power conversion 2 again, give each chip power supply of mainboard including interface FPGA.The processor of RRU mainboard arranges an alarm voltage threshold to voltage detecting warning circuit, and this threshold de is the 70% of main running voltage, and namely the power supply of main power source is reduced to voltage detecting warning circuit output power fail warning signal during the 70% of rated voltage.After the under-voltage point that main power voltage is reduced in plate power conversion 1 after a period of time again, mainboard power down is closed.Voltage change process is as shown in Figure 7；Wherein, being 1. the initial time of mainboard power down, in the moment 2. produced for power fail warning signal, 3. for closing power amplifier module and reporting the moment of power fail warning, be 4. the moment of mainboard power down.
Include referring to Fig. 8, RRU power fail warning workflow:
S801, RRU main power source starts power down；

S804, FPGA close power amplifier module, and warning information packing are reported；
S805, BBU receive warning information and report OMC；
S806, board power down, flow process terminates.
In mainboard, the under-voltage point of the input voltage of Power convert 1 have to be lower than alarm electrical voltage point, and so after power fail warning signal produces, each chip of mainboard can also work on a period of time.Voltage detecting warning circuit output power fail warning gives FPGA; FPGA closes power amplifier module at once; power amplifier module is made to quit work; the closedown of power amplifier module had both protected power amplifier and had been not damaged by power down process; alleviate the load of main power source so that in mainboard, Power convert 1 can provide the supply voltage of longer time simultaneously.It addition, FPGA packs relevant warning information while receiving power fail warning signal, report BBU, BBU by IR interface and report OMC-R again, thus achieve reporting of RRU power fail warning information.
