Shenzhen Friendcom Technology Development Co., Ltd. engaged in Researching & Development of electric power meter-reading, wireless data communication and electric power products for many years. According to current problem of multi-functional power meter data-reading, checking-time and programme; we promote a best solution---Embedded Meter-Reading system which embed a small wireless data module into multi-functional power meter to realize data communication by wireless and two-way transmission.
Design concept:
1. Newest: Using wireless data transmission and computer to realize power meter data-reading, checking-time and programme remotely.
2. Easy-use: Not need go out of the power meter-reading control centre, Just using wireless hand-held receiver, wireless meter-reading car or wireless relay transmission this three way for data reading.
3. Easy-installed: Modular design, small and line-easy, embedded data transceiver directly install in power meter.
4. Non-apply frequency band: Use the free-apply wireless measure frequency in China.
Main Features:
Wireless self organized mesh network, robust and reliable
Strong performance of each node with good penetrating capability
Self adapting frequency hopping to enhance the anti-interference performance of system
Intellectualized installation: plug-and-play, no need to configure on site or configure before installation
High data transmission speed: 19,200bps
Supports DL/T 698 and 645 protocols
