Description

A method for on-line monitoring of storage battery of communication network equipment

technical field

The invention relates to the monitoring of electrical equipment, in particular to a method for on-line monitoring of storage batteries in communication network equipment.

Background technique

Telecommunications equipment usually adopts a DC power supply system, and the DC power supply system generally uses a battery as a backup power supply. According to the provisions of the telecommunications power supply maintenance regulations: the battery should be subjected to a discharge test with a discharge depth of 30% to 40% once a year; a 100% capacity test should be performed every three years (once a year after 6 years of use). The current test is generally carried out by the maintenance personnel to the scene to carry out the discharge test on the battery. Due to the wide distribution of telecommunications network equipment and many equipment distribution points, the workload of battery maintenance is very large; and the discharge test on site has a great impact on the safety of equipment operation. It poses a threat, so many places do not carry out testing and inspection according to the regulations, which brings hidden dangers to the operation of telecommunications network equipment. If the failure of the battery is not found in time, once the mains power fails and the communication is interrupted, it will cause a major accident.

The management part of the equipment and power supply in the telecommunication network management system has the management of the battery. At present, it is only the floating charge control of the battery and the low-voltage protection control, and the detection of the capacity and state of the battery is not done. Early warning.

At present, there are many test instruments for the detection of battery capacity and state, which generally require on-site discharge detection. For example, the application number published on July 28, 1999 is 98208658.X, a utility model named on-line automatic battery tester, and the application number published on December 5, 2001 is 01213262.4, a utility model named battery inspection and monitoring device , respectively revealing an instrument for testing batteries, but these instruments need to be brought to the site by maintenance personnel and connected to the battery for testing. Although the batteries can be tested one by one online, they cannot be uniformly monitored and managed for all batteries in the network. Maintenance personnel need to go to the site to carry out inspections, so the monitoring workload is very heavy, and it is impossible to predict when the battery fails, so accidents caused by battery failures may occur, which will bring hidden dangers to the operation of telecommunications network equipment.

In the existing telecommunications network equipment, the maintenance and management of the storage battery by the network management system is relatively simple, which cannot meet the actual use requirements. Battery maintenance and management has always been a work with a large workload in the maintenance and management of network equipment, and the actual effect is not very ideal.

The power monitoring system is a power monitoring board installed in the communication network equipment, which collects the charging or discharging current from the shunt of the distribution board, and collects the terminal voltage or the voltage of the battery from the battery terminal, and through the power monitoring A temperature sensor is installed on the board to collect the battery temperature.

The power monitoring system is also provided with a central processing unit (CPU), which processes the collected data, and connects with the communication network equipment through the serial port, and transmits the data to the network management system through the communication network equipment.

The network management system will give an alarm to the battery that has failed by means of sound and light.

The network management system can set the cycle of data collection as required.

The period ranges from 1 second to 60 minutes.

The power monitoring system can control the switch of the DC power supply, conduct the discharge and charging test on the storage battery through the remote control of the network management system, and analyze the test data collected by the power monitoring system on the network management system side.

The beneficial effects of the present invention are: the present invention uses the network management system and the power monitoring system to collect and record data on the battery charging and discharging process of the communication network equipment, and uses the battery expert system to judge the health status of the battery in real time and diagnose the faulty battery , early warning, etc., which reduces the workload of equipment maintenance personnel. Early warnings are given on the network management alarm platform for batteries that may fail, and alarms are issued for batteries that have failed by sound and light, thereby reducing the impact on telecommunications network equipment due to battery failures. The hidden dangers brought by the operation safety have improved the safety of the equipment operation and greatly reduced the maintenance cost.
