Embodiment 1

[0028] A power failure detection method, comprising:

[0029] S11. Obtain the state of the alternating current, the state of the alternating current includes the frequency and voltage of the alternating current;

[0030] Obtain the FSU port type, and determine the output signal type according to the FSU port type. In this embodiment, the FSU can receive voltage signals;

[0031] S12. Judging the operation of the AC power, if the voltage is 176~264V and the frequency is 49.9~50.1Hz, the judgment conclusion is that the AC power is running normally and the output is high voltage;

[0032] If either the voltage is less than 176V or the frequency shifts >0.1Hz, it is judged that the AC power is running abnormally and the output voltage is low.

[0033] The traditional power-off sensor realizes power-off detection and signal output by connecting circuit components, such as inverters and other components. The connection between circuit components is usually complicated; the operatio...

Embodiment 2

[0035] A power failure detection method, comprising:

[0036] S11. Obtain the state of the alternating current, the state of the alternating current includes the frequency and voltage of the alternating current;

[0037] Obtain the FSU port type, and determine the output signal type according to the FSU port type. In this embodiment, the FSU can receive current signals;

[0038] S12. Judging the operation of the AC power, if the voltage is 176~264V and the frequency is 50±0.1Hz, the judgment conclusion is that the AC power is running normally and outputs a large current;

[0039] If either the voltage is less than 220V or the frequency shifts >0.1Hz, it will be judged that the AC power is running abnormally, and a small current will be output.

[0041] A power failure sensor, comprising:

[0042] S11. Obtain the state of the alternating current, where the state of the alternating current includes the frequency of the alternating current;

[0043] Obtain the FSU port type, and determine the output signal type according to the FSU port type. In this embodiment, the FSU can receive voltage signals;

[0044] S12. Judging the operation of the AC power, if the frequency is 49.9~50.1Hz, the conclusion is that the AC power is running normally and the output is high voltage;

[0045] If the frequency deviates >0.1Hz, it is judged that the AC power is running abnormally and the output voltage is low; or it is judged as self-generating.

Abstract

The invention relates to the field of communication base station electric control, and provides a power-off detection method and a power-off sensor. The invention aims to solve the problem that base station power supply cannot be effectively controlled. The invention provides a power failure sensor. The power-off sensor comprises S11, acquiring an AC state; and S12, judging the operation conditionof the AC, and outputting a signal according to the operation condition of the AC. Through optimization of the method, the construction management and control link during installation is simplified,on-site construction is facilitated, and the number of circuit elements is reduced.

Description

technical field [0001] The invention relates to the field of electric control of communication base stations, in particular to a power failure detection method and a power failure sensor. Background technique [0002] At present, the power outage monitoring of communication base stations mainly collects power outage information through switching power supplies, and uploads them to the operation and maintenance system through the communication interface through the dynamic ring FSU. However, due to the stock switching power supply, a considerable part of the communication interface and monitoring modules are faulty, and the power failure information cannot be obtained in time, and the power generation cannot be distinguished from the normal mains power supply. There is no effective means to control the timeliness of power generation of communication services and trustworthiness of power generation. [0003] In the prior art, power failure detection is mainly realized through...
