Description

A method and device for replacing a surge protector for a communication base station

technical field

The invention relates to the technical field of communication, in particular to a method and device for replacing a surge protector used in a communication base station.

Background technique

Communication base station, also known as wireless base station, is a form of radio station. In the limited radio coverage area, the communication base station can carry out information transfer with the mobile phone terminal through the mobile communication switching center.

Communication base stations include weak current equipment such as control devices, transmission equipment, and power supply equipment. In thunderstorm weather, when the communication base station is struck by lightning, the strong current generated by the lightning strike can counter-discharge the weak current equipment in the communication base station. However, the withstand overvoltage capability of weak current equipment is far less than the thousands of volts generated by lightning strikes, so weak current equipment is prone to damage under lightning strikes. Therefore, in order to make the communication base station operate safely and stably, it is necessary to pay strict attention to lightning protection.

At present, the lightning protection measures for communication base stations are mainly scattered installation of surge protectors in each screen cabinet. In thunderstorm weather, the lightning current generated by the lightning strike can interfere with the electrical circuit or communication line. The surge protector can detect the lightning current and turn on the shunt in a very short time, so as to avoid damage to other equipment in the circuit. For the shared power tower communication base station, the geographical location of the communication base station is relatively remote. When the surge protector is damaged and needs to be replaced manually, it is difficult to replace the surge protector due to the remote location of the communication base station, and the labor cost is high.

Detailed ways

Please refer to accompanying drawing 1, which shows a schematic flowchart of a method for replacing a surge protector for a communication base station provided by an embodiment of the present invention. It can be seen from Figure 1 that the surge protector replacement method for communication base stations provided by the embodiment of the present invention includes:

S01: The data acquisition module separately collects the leakage current values of multiple surge protectors, and processes the leakage current values; wherein, one of the surge protectors is a running surge protector, and the remaining surge protectors are Backup surge protector.

In order to facilitate the automatic replacement of surge protectors, multiple surge protectors are provided, and multiple surge protectors are connected in parallel to prevent that when one surge protector is damaged, other surge protectors cannot be connected to the communication system. At the same time, multiple surge protectors are connected to the line selection module through a wire, so that voltage can be applied to the multiple surge protectors through the line selection module at the same time. Among multiple surge protectors of the same model, only one surge protector is in the lightning protection state, that is, in the operating state. In the embodiment of the present invention, a surge protector in an operating state is referred to as an operating surge protector. The rest of the surge protectors are not connected to the circuit to be protected, but their respective leakage currents are monitored in real time, so as to judge whether the surge protectors can be replaced by the monitored leakage currents, that is, the remaining surge protectors are in a standby state . In the embodiment of the present invention, the surge protector in standby state is referred to as standby surge protector.

Since all surge protectors are applied voltage by the line selection module, the surge protectors will generate a very small current, that is, leakage current. The leakage current generated by each surge protector has a certain threshold value. When the threshold value is exceeded, it means that the surge protector has been damaged and can no longer be used for lightning protection. In order to detect the leakage current generated by each surge protector, each surge protector is connected in series with a microammeter.

The data acquisition module separately collects leakage current values detected by multiple microammeters, and performs data processing on the leakage current values through a digital signal processor. The data acquisition module sends the data-processed leakage current value to the control module, so that the control module can judge the processed leakage current value.

S02: The control module judges whether the leakage current value is smaller than a preset leakage current threshold.

After receiving the processed leakage current value sent by the data acquisition module, the control module judges whether the surge protector generating the leakage current is damaged by judging the magnitude between the leakage current and the preset leakage current threshold. That is, it is judged whether the leakage current value is smaller than a preset leakage current threshold.

S03: If less than, do not replace the operating surge protector.

When the leakage current is less than the preset leakage current threshold, it means that the leakage current generated by the surge protector does not exceed the preset leakage current threshold, the surge protector is not damaged, and has lightning protection performance. At this time, the surge protector should continue to be used for lightning protection, that is, the operating surge protector should not be replaced.

S04: If it is greater than or equal to, control the line selection module to replace the running surge protector.

When the leakage current is greater than or equal to the preset leakage current threshold, it means that the leakage current generated by the surge protector exceeds the preset leakage current threshold, and the surge protector has been damaged and has no lightning protection performance. At this point, the running surge protector should be replaced.

specifically,

S041: The control module sends replacement information to the line selection module; the replacement information includes replacing the running surge protector with the backup surge protector.

When the surge protector needs to be replaced, the control module sends replacement information to the line selection module, and the replacement information includes replacing the running surge protector with a standby surge protector.

S042: The line selection module disconnects the operating surge protector from the communication line, and connects the backup surge protector corresponding to the leakage current value less than the preset leakage current threshold to the communication line line.

Since the control module can monitor the leakage current of each surge protector, the control module can monitor the lightning protection performance of each surge protector in real time. The line selection module disconnects the operating surge protector from the communication line according to the received replacement information, and connects the backup surge protector corresponding to the leakage current value less than the preset leakage current threshold to the communication line, so as to replace the surge protector. The purpose of the protector.

Further, the method for replacing a surge protector for a communication base station provided by an embodiment of the present invention further includes:

S05: Generate a line selection result, the line selection result including the time, serial number, type and manufacturer of the backup surge protector.

After the surge protector is replaced by the line selection module, a line selection result is generated, and the line selection result includes the time, serial number, type and manufacturer of the backup surge protector.

S06: Store the line selection result.

The line selection module sends the line selection result to the control module, so as to be stored in the database in the control module, and then to facilitate the later performance analysis and selection of the surge protector.

Corresponding to the method for replacing a surge protector for a communication base station provided by the embodiment of the present invention, the embodiment of the present invention also provides a device for replacing a surge protector for a communication base station, as shown in FIG. 2 .

It can be seen from FIG. 2 that the surge protector replacement device for communication base stations provided by the embodiment of the present invention includes a plurality of surge protectors 1 of the same type, such as the big circle in FIG. 2 . Among multiple surge protectors 1 of the same model, only one surge protector 1 is in a lightning protection state, that is, in an operating state. In the embodiment of the present invention, the surge protector 1 in the running state is called a running surge protector. Although the remaining surge protectors 1 are also connected to the communication circuit, they are not in the lightning protection state, that is, the standby state. In the embodiment of the present invention, the surge protector 1 in standby state is called a standby surge protector. Multiple surge protectors 1 are connected in parallel to prevent that other surge protectors 1 cannot be connected to the communication system when one surge protector 1 is damaged. At the same time, multiple surge protectors 1 are connected to the line selection module 5 through a wire, so as to apply voltage to multiple surge protectors 1 through the line selection module 5 at the same time.

Since all the surge protectors 1 are supplied with voltage by the line selection module 5, the surge protectors 1 will generate a very small current, that is, leakage current. The leakage current generated by each surge protector 1 has a certain threshold. When the threshold is exceeded, it means that the surge protector 1 has been damaged and cannot be used for lightning protection. In order to detect the leakage current generated by each surge protector 1, each surge protector 1 is connected in series with a microammeter 2, as shown in the small circle in Fig. 2 . More preferably, the high voltage end of the surge protector 1 is connected to the line selection module 5 , and the low voltage end is connected to the microammeter 2 .

In addition, multiple surge protectors 1 are respectively connected to the data acquisition module 3 and the line selection module 5 , and both the data acquisition module 3 and the line selection module 5 are connected to the control module 4 . The data acquisition module 3 is used to collect the leakage current detected by the microammeter 2, and perform data processing on the collected leakage current, so that the control module 4 can judge the lightning protection performance of the processed leakage current value.

After receiving the processed leakage current sent by the data acquisition module 3, the control module 4 judges whether the surge protector 1 generating the leakage current is damaged by judging the magnitude between the leakage current and the preset leakage current threshold. Specifically, when the leakage current is less than the preset leakage current threshold, it means that the leakage current generated by the surge protector 1 does not exceed the preset leakage current threshold, and the surge protector 1 is not damaged and has lightning protection performance. At this time, the surge protector 1 should continue to be used for lightning protection. When the leakage current is greater than or equal to the preset leakage current threshold, it means that the leakage current generated by the surge protector 1 exceeds the preset leakage current threshold, and the surge protector 1 has been damaged and has no lightning protection performance. At this time, the running surge protector 1 should be replaced. Since the control module 4 can monitor the leakage current of each surge protector 1, the surge protector replacement device for communication base stations provided by the embodiment of the present invention can monitor the lightning protection performance of each surge protector 1 in real time.

When the control module 4 determines that the operating surge protector 1 needs to be replaced, the control module 4 sends replacement information to the line selection module 5, and the replacement information includes replacing the operating surge protector with a standby surge protector. The line selection module 5 disconnects the operating surge protector from the communication line according to the received replacement information, and connects the backup surge protector corresponding to the leakage current value less than the preset leakage current threshold to the communication line, so as to achieve the purpose of replacing the surge protector. Purpose of surge protector 1. After the replacement is completed, the line selection module 5 generates a line selection result, which includes the time, serial number, type and manufacturer of the backup surge protector. The line selection module 5 sends the line selection result to the control module 4, so as to be stored in the database in the control module 4, so as to facilitate the performance analysis and selection of the surge protector 1 later.

The surge protector replacement method and device for communication base stations provided by the embodiments of the present invention judge the surge by judging the magnitude between the leakage current value leaked from each surge protector and the preset leakage current threshold The lightning protection performance of the protector can be used to determine whether the operating surge protector is damaged. If the leakage current value is less than the preset leakage current threshold, it means that the operating surge protector has lightning protection performance and can be used normally. If the leakage current value is greater than or equal to the preset leakage current threshold, it means that the operating surge protector does not have lightning protection performance and needs to be replaced, so as to achieve the purpose of real-time lightning protection through the replacement of the surge protector. In addition, since the surge protector can be replaced automatically, labor costs can be greatly reduced.
