Smart grid is the focus development direction of the national power grid construction, and remote power information collection is the important part of smart grid. The existing automatic meter reading system of remote electric power information collection has such problems as high cost, big power consumption, small networking and big line interference etc. Aim at these features, this paper prop...

Preproduction and current models of the miniature Wright peak flow meter have been compared with the standard Wright peak flow meter on normal and abnormal subjects. Early problems in production appear to have been overcome, and the current model agrees to within 3% with the standard peak flow meter, which is as close as the agreement between two standard instruments. The new mini-meter may be ...

In this research paper,the proposed concept is to replace the traditional manual meter reading. Now a days the traditional manual Meter Reading was not suitable for longer operating purposes as it spends much human and material resource. It brings additional problems in calculation of readings and billing manually. The number of Electricity consumers is increasing in great extent. It became a h...

With the rapid development of wireless technologies, it is possible for Chinese automatic meter reading system (AMRS) to be equipped with wireless sensor networks due to their low-cost, simplicity and mobility. In the current study, we compared the advantages of ZigBee with other two similar wireless networking protocols, Wi-Fi and Bluetooth, and proposed a wireless solution for AMRS based on Z...
