电力远程抄表系统（Power remote meter reading system） Constitution of power remote meter reading system: At present, the electricity sales center found that individual users steal electricity phenomenon is quite serious, when the examination and to obtain evidence, causing serious economic losses to the hydropower plant, how to carry out real-time electricity monitoring for suspicious users, electricity abnormal alarm, power supply department to become the urgent problems to be solved. A phased examination of each important pass and circuit also requires a flexible, remote monitoring system for reading multiple energy meters. Radio energy measurement monitoring and alarm system is designed to resolve the problems, it uses SMS transmission GSM, 485 communication interface, handling is very convenient, and can transmit the alarm information in the form of text messages sent to the staff on the mobile phone. Because the mobile communication is adopted, the utility model can be installed on the line which needs to be checked at any time to monitor the transmission. At present, the cable data transmission mode is used by most of the domestic and international electric power meter, that is, the data transmission mode of the dedicated line, the data transmission mode of the telephone line and the carrier data transmission mode. The wireless data transmission mode can be divided into microwave data transmission mode, radio data transmission mode and GSM and GPRS network data transmission mode. In the wireless data transmission mode, the microwave data transmission is expensive, the data transmission of the radio is high, and the maintenance cost is great. Short message transmission (SMS) of GSM and GPRS networks has become the trend of short data transmission because of its increasing coverage, low cost and high stability. It is suitable for single station energy meter monitoring. The radio energy measurement monitoring and alarm system, it is the use of GSM network transmission tech
