1) running status of monitoring power supply main frame, current data (frame 2102) on the RF cable that frame 2101 acquisition monitorings power supply slave connects, the data that collect in frame 2105 are analyzed, if analyze data after-current normal (frame 2107) then turn back to frame 2101, enter circulation next time, if the analysis after-current is crossed (stream frame 2108) then is carried out following two processes, the output of 1, cutting off the electricity supply (frame 2113), 2, produce switching value data (frame 2112), and transmit switching value and alarm BTS (frame 2116).So just finished of monitoring and the protection of monitoring power supply main frame to power supply.
2) receive the data (frame 2103) of monitoring the power supply slave, then in frame 2106, analyze the type of data, if in frame 2103, receive it is the operating state data of monitoring power supply slave, then return frame 2101, if in frame 2103, receive it is the alarm data (frame 2109) of monitoring power supply slave, then produce switching value alarm data (frame 2114) and transmit switching value and alarm BTS (frame 2117).So just finish the processing of monitoring power supply slave warning information and upload.
3) timer is set in the regularly instruction (frame 2104) of the transmission inquiry slave status of circulation of monitoring power supply main frame running status frame 2101 then, if receive the operating state data that monitoring power supply slave returns at the appointed time, then forwards frame 2103 to.If do not receive monitoring power supply slave operating state data (frame 2111) at the appointed time, then produce switching value alarm (frame 2115) and transmit switching value and alarm BTS (frame 2118).
Monitor the workflow of power supply slave as shown in figure 22:
1) running status of monitoring power supply slave, the current data (frame 2202) that frame 2201 is gathered the trunk amplifier power supply, the data that collect in frame 2205 are analyzed, if analyze data after-current normal (frame 2208) then turn back to frame 2201, enter circulation next time, if analyze after-current overcurrent (frame 2209), then carry out following two processes, 1, cuts off output (frame 2213), 2, produce warning information and send a warning message monitoring power supply main frame (frame 2212) to the trunk amplifier power supply.So just finished of monitoring and the protection of monitoring power supply slave to power supply.
2) receive monitoring power supply host query data (frame 2203), then send response message, send and be back to frame 2201 after response message is finished, enter circulation next time at once to monitoring power supply main frame (frame 2206).
3) output level, the standing wave data (frame 2204) of monitoring power supply slave collection trunk amplifier.The data that collect are analyzed (frame 2207), if image data is in setting the threshold value scope (frame 2210), then turn back to frame 2201, set threshold value (frame 2211) if image data exceeds, then generate alarm data and send alarm data to monitoring power supply main frame (frame 2214).
