Design And Implementation Of Remote Monitoring System For Battery Based On Network Technology

With the advance of modern technology, people are increasingly high demand for continuous uninterrupted power supply. When the fault occurs, the battery is one of the main backup power supply which is effective and real-time switching. In order to prevent battery from causing bad risks for long time stand-by state, real time on-line monitoring the battery is required. This thesis is the real-time online monitoring the working voltage, temperature, resistance and current of backup power supply battery, to ensure its stable and reliable work, and it has important practical significance for the safety, stability and reliability of equipment operation.Sensor technology, computer technology, modern communication technology and network technology are applied to construct three-tier network architecture included the battery data acquisition node, data concentrator, and monitoring PC, to design battery remote monitoring system based on network technology in this paper. Battery parameter acquisition node adopts LEM sentinel sensors and current transformer to collects the battery voltage, temperature, resistance and current respectively. Concentrator included S-BUS data converter, STM32 control board, A/D conversion module of current signal acquisition, upload module of battery data server, completes the functions of communication between LEM sensor and concentrators and collection of current data, and sends battery parameter data packet to the PC server database through the GPRS wireless communication. At the same time, the concentrator can complete the functions of setting alarming parameters threshold of the battery, driving buzzer alarm when parameter exceeds a threshold, real-time display of battery parameters and real-time clock display. The system monitoring uses B/S architecture, using VC++6.0 to design data receiving server to process battery data uploaded to the server; Using WAMP software portfolio to design website management platform, after reading the data from the server, the parameters and performance of the battery are displayed on the website interface. At the same time, the website platform can realize the user management, historical data query, setting the battery parameter alarm threshold, and using sound or image to prompt the user to deal with abnormal battery. The system enables users to easily realize the remote monitoring of battery data through the browser networking access server.Under the premise of ensuring to satisfy the comprehensive, quick and accurate collection of battery parameters, the monitoring system reduce the workload of staff, enable the staff to detect and deal with abnormal battery in time, ensuring the safe and stable operation of the backup power supply system. At the same time, the related users can realize the remote query of the monitoring information at any time. The implementation of the system provides a reference for the further research of battery monitoring.
