Development Of Lead Acid Battery Monitoring System Based On LabVIEW

With the development of communications, electronics and energy technologies, batteryis more and more used in civil and industry fields. Lead-acid battery is a most popular varietyfor a long time because of its good performance, rich primary material and low prices etc. Itwill directly affect its usage performance and life@an, if the lead-acid battery is notappropriate to be maintained. What's worse, it may damage the battery and cause safetyaccidents. The battery's working state, operating characteristic and maintaining condition canbe obtained by on-line monitoring battery's working parameters. So, it is a trend to developon-line monitoring system for lead-acid battery.At present, most countries in the world are studying lead-acid battery's automaticmonitoring devices to satisfy actual needs of industry, agriculture, social use and defenses.The Virtual Instruments is a new technology, which sets up a friendly man-machineinteractive interface by pc's powerful data-handing ability, graph environment and on-lineaiding function. It can control the test object and realize data acquisition, analysis and display.It has a good network interface.A useful automatic monitoring system for lead-acid battery was developed in this paperbased on LabVIEW. It can real-time monitor multiloop batteries. It was convenient to set upnetwork to share information and was to development direction of modern test macro. Themain contents of the paper were as below:1. The monitoring system for lead-acid battery was presented based on VirtualInstruments and LabVIEW7.0. Monitoring items and indexes were educed by studyinglead-acid battery's basic working principle and electrical properties.2. The configuration and test of hardware, such as selecting logical acquiring modes,assigning acquiring channels and configuring each channel's parameters, were finished. All ofthese were to improve anti-jamming ability of the system. 3. The software programming of the IPC was completed based on LabVIEW7.0. Thecommunication between IPC and DAQ card was realized. All parts of the system wereintegrated.4. The network interface program was developed based on the DataSocket technology.The monitoring system can be remote accessed and remote controlled. Then, its networkingwas realized.
