Description

Technical Field

[0001] The present invention relates to the technical field of power supply guarantee for communication base stations, and in particular to a power supply guarantee method and device for a communication base station. Background Art

[0002] Communication base stations may experience short-term power outages due to factors such as tight power supply, limited grid capacity, grid transformation, and disaster damage. During power outages, the base station equipment mainly relies on backup batteries in the base station to maintain normal operation. However, the life of the battery pack is affected by the number of charge and discharge times, and the capacity decreases year by year. Especially in mountain base stations, remote base stations, and base stations besieged by disasters, when power outages occur, the communication base station operation and maintenance unit needs to rush to the base station to perform on-site power generation operations before the battery pack runs out of power. Due to the short battery life of the battery pack in the base station, the response time left for the operation and maintenance unit will be very limited. If manpower cannot reach the base station site in a short time to handle the problem, the base station will be shut down due to power outages, causing communication network interruptions and economic losses. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a power guarantee method and equipment for a communication base station. The method is aimed at: when a power supply interruption occurs in the power grid, the communication base stations in high mountains or remote areas often cannot leave too much emergency response time for the operation and maintenance units. Therefore, a method and related equipment specifically for power guarantee of base stations are needed, which can achieve remote power grid power outage alarm, automatic or remote control of the start and stop of the gasoline generator in the base station, and minimize the occurrence of communication network interruption accidents caused by base station shutdowns.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A method for ensuring power supply of a communication base station, comprising:

[0006] Step A collects on-site electrical data of the base station and encrypts the electrical data and transmits it to the communication server;

[0007] Step B: the communication server saves the received electrical data and forwards it to the remote control device;

[0008] Step C: When the power supply of the power grid is interrupted, it is automatically determined whether the power supply of the battery pack is normal. If the power supply of the battery pack is abnormal and the generator is capable of generating power, the generator is automatically started and the base station power supply line is switched to the generator output; if the power supply of the battery pack is normal, the power supply data is monitored in real time, and the operation of remotely starting the generator is retained;

[0009] In step D, the power supply of the power grid returns to normal, and the control program in the remote control device stops the generator and the infrared encoder and restarts the air-conditioning equipment in the base station; and the power outage fault and related operation data are included in the model training set.

[0010] A power supply device for a communication base station, comprising:

[0011] An embedded device for collecting on-site electrical data from the base station and encrypting and transmitting the electrical data to the communication server;

[0012] The communication server is used to store the received electrical data; control and send instructions to the automatic control device according to the base station field data;

[0013] Automatic control device, controlling the start and stop of the power generation device in the base station;

[0014] And when the power grid is normal, the infrared encoder can be used to restart the air-conditioning equipment in the base station.

[0015] Compared with the prior art, one or more embodiments of the present invention may have the following advantages:

[0016] The controller composed of a specific embedded system has the functions of field data collection and generator start and stop control. The controller itself also has its own power supply, which can rely on its own power to complete the operation and maintenance of communication base station power generation during power outages, and can cope with the problem of delayed operation and maintenance of base stations in high mountains or remote areas.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with embodiments and drawings.

[0020] like Figure 1 As shown, the power guarantee method flow of the communication base station includes the following steps:

[0021] Step 10 collects the on-site electrical data of the base station, and encrypts the electrical data and transmits it to the communication server;

[0022] The electrical data includes power supply signal of the power grid, voltage signal of the battery pack, fuel level signal of the generator, and voltage signal of the generator battery, which are encrypted and transmitted back through the MQTT protocol.

[0023] Step 20: the communication server saves the received electrical data and forwards it to the remote control device;

[0024] Step 30: When the power supply of the power grid is interrupted, it is automatically determined whether the power supply of the battery pack is normal. If the power supply of the battery pack is abnormal and the generator is capable of generating power, the generator is automatically started and the base station power supply line is switched to the generator output; if the power supply of the battery pack is normal, the power supply data is monitored in real time, and the operation of remotely starting the generator is retained;

[0025] Step 40: When the power supply of the power grid returns to normal, the control program in the remote control device stops the generator and the infrared encoder and restarts the air conditioning equipment in the base station; and the power outage fault and related operation data are included in the model training set.

[0026] The above step 10 specifically includes: collecting the electrical signal grid power supply signal U w , the voltage signal of the battery pack in the base station U b1 , generator battery voltage signal U b2 , generator oil level signal O, generator status signal S, ambient temperature and humidity signal H, time cutoff T, combined into a JSON string, with the server heartbeat packet information M as the secret key, encrypted by BlowFish to form information D, MQTT protocol back to the server:

[0027] D = f bf (f json (U w , U b1 , U b2 , O, S, H, T), M).

[0028] The operation of remotely starting the generator in step 30 above:

[0029] Generator Operation:

[0030] In the above step 40, the power outage fault and related operation data T are included in the model training set:

[0031] T training ={T1, T2, T3, ..., T n}.

[0032] This real-time example also provides a power guarantee device for a communication base station, including: an embedded device for collecting on-site electrical data of the base station and encrypting the electrical data and transmitting it to a communication server; a communication server for storing the received electrical data; controlling and sending instructions to an automatic control device based on the on-site data of the base station; an automatic control device for controlling the start and stop of a power generation device in the base station; and a function for restarting the air-conditioning equipment in the base station using an infrared encoder when the power grid is normal.

The automatic control device includes charging module, communication module, infrared transmitting / receiving module, oil engine controller and debugging serial port (such as Figure 2 shown).

If the battery pack is supplying power abnormally and has the conditions for power generation, the generator will be automatically started and the base station power supply line will be switched to the generator output; if the battery pack is supplying power normally, the power supply data will be monitored in real time, and the operation of manually starting the generator remotely will be retained. The instructions for starting the generator are as follows:

[0039]

[0040] 3. When the power grid returns to normal, the generator can be stopped through the automatic control program and the air conditioning equipment in the base station can be restarted using infrared coding. The instructions for restarting the air conditioner are as follows:
