The communication battery is an important part of the communication system. It is the guarantee for the reliable operation of the communication under the condition of AC power failure, and it is of great significance to the operation of the communication system.

Communication operators generally have dedicated power supply maintenance personnel, but the power system does not have dedicated communication power supply maintenance personnel, resulting in inadequate maintenance of communication power supply, which often leads to a decrease in battery capacity. Interruption of power grid data transmission affects power grid accident handling.

With the increasing scale of the power grid and the improvement of the automation level, the safe operation of the power grid is increasingly dependent on the dedicated communication network. According to the communication regulations of the State Grid Corporation of China, the power communication network must have its own independent power supply system. Therefore, in In the power communication network, the power supply and battery are a huge system, and each communication station is equipped with corresponding rectification equipment and batteries to ensure the normal operation of communication equipment under the condition of AC mains.

A large number of substations are scattered in the suburbs and generally unattended. The battery should be charged and discharged twice a year to ensure the capacity and service life of the battery. If special personnel are sent to the site to charge and discharge the battery, it takes 4 days for a station to charge and discharge the battery every year. Communications under the jurisdiction of the power grid in general areas There are more than 100 stations. At the same time, the communication personnel are also responsible for the infrastructure construction and daily operation and maintenance of the communication station. It can be seen that relying on manual on-site charging and discharging is an extremely heavy task, which is actually difficult to do.

The discharge load is installed in the communication substation, and is used for series connection with the storage battery of the same communication substation to accelerate the discharge of the storage battery. Adding a discharge load can increase the discharge current, shorten the battery discharge time and meet the battery discharge standard. The standard takes 10%, that is, 0.1C, 10 hours of discharge rate, according to the current configuration ratio of battery capacity (large) and load (too small) in the power communication network, if no discharge load is added, the discharge time will be very long, due to the self-discharge of the battery Recovery characteristics, when the load is too small to discharge, the detection of the true capacity of the battery is inaccurate. The discharge load can be a fixed resistance load with a rated working voltage of -48V and a rated current of 10/20A/30A. Considering the problem of heat dissipation and fault point, the discharge load can be installed in the room outside the communication room, or on the top of the equipment.

The power monitoring unit is also used to monitor the battery voltage when the battery is discharging, and disconnect the discharge load to stop discharging when the voltage value is lower than the set over-discharge protection value.

The battery inspection device is located in the communication substation and adopts the CBS01A battery inspection device, which includes a host (CBS01A distributed battery inspection device) and one or more battery data acquisition units (BMCU01A). Each battery data acquisition unit is used for real-time monitoring and acquisition of the charging and discharging status of the battery. The operating parameters include: charging current, discharging current, group voltage, internal resistance and voltage of each battery. Each battery data acquisition unit is connected to the host through the RS485 interface. Each battery data acquisition unit detects 24 single batteries, and the user can configure 1-10 according to needs, and can detect up to 240 batteries. The host of the battery inspection device (CBS01A distributed battery inspection device) stores and analyzes the collected battery data.

There is an alarm unit inside the host, and when the host analyzes and finds that the battery is in an abnormal state, the alarm unit sends out an alarm. The host computer can also carry out remote transmission through RS-485 or RS-232, and transmit the data to the remote computer in real time. The remote computer can send out warnings and provide data printing at any time. CBS01A battery inspection instrument parameters: rated working voltage -48V, 24 sections/group, each set of inspection instrument should meet the requirements of 48 sections.

The substation communication server is set in the communication substation, and is used to collect the data collected by the power monitoring unit and battery inspection device of the same communication substation and send it to the communication server of the main station, and receive the remote control command sent by the communication server of the main station and send it to the power supply The monitoring unit; the communication server of the substation is connected with the battery inspection device and the power monitoring unit of the same communication substation respectively through the RS485 interface. The communication server of the substation is connected with the communication server of the master station through RS232 or RS485 or Ethernet.

As shown in Figure 2, the working process of the communication network battery remote monitoring system:

Open the power monitoring system software on the remote computer, set the discharge termination voltage, start the discharge function, and issue a discharge command. The discharge command is sent to the sub-station communication server through the communication server of the main station and further through the RS232 or RS485 interface or Ethernet. The substation communication server sends it to the power monitoring unit, and the power monitoring unit responds by disconnecting the rectifier module and connecting the discharge load to the circuit. The discharge load starts, the rectifier module is in the thermal standby state (the module voltage is automatically lowered to the battery discharge termination voltage value), and the system is in the discharge monitoring state.

During discharge, the power monitoring unit detects the battery parameters during discharge, including: discharge time, discharge capacity, and discharge current. The above parameters will automatically pop up on the display screen of the power monitoring unit, and the corresponding parameters will also be displayed on the remote computer.

When the discharge reaches the preset end-of-discharge voltage, the power monitoring unit cuts off the discharge load and puts the rectifier module into operation, so that the rectifier module can evenly charge the battery while supplying power to the equipment. At the same time, the power monitoring unit sends a discharge completion instruction to the remote computer through the substation communication server and the main station communication server.

During the charging process, the power monitoring unit monitors the voltage, current and other information of each single battery and sends them to the remote computer.

When the charging reaches the preset level (the voltage reaches a certain upper limit, which is also preset by the power monitoring system of the remote computer), the rectifier module will automatically turn to the floating charging state. At the same time, the power monitoring unit sends a charging completion command to the main station.

When charging and discharging, the battery data acquisition unit of the battery inspection device monitors and records the charging and discharging status of each single battery, including voltage, current and other information, and transmits it to the remote computer of the communication master station. After the charging/discharging is finished, the data of the storage battery pack and each single battery can be called out from the database of the remote computer (the remote database of the battery inspection device), and can be printed out.
