摘要
现有居民集抄系统存在抄表数据误差多、系统投入使用后仍需大量维护工作等问题。在对原有系统构成及各环节存在不足进行分析的基础上,提出采用新技术对原有系统加以改进,包括采用表计RS485口通信、电力线载波采用工频传输方式和基于GPRS/GSM方式上传数据等。改进系统的抄表成功率达到100%,系统性能得到提高。
The present residential integrated metering sys-tern has the problems of many errors and large amount of mainte-nance. The paper brings out that the system should be reformed through using new technology including 485 communication interfaee, electric power line carrier power-frequency transmitting and uploading data with GPRS/GSM. After the reformation the success rate can get 100%. The system performance improves greatly.
