Embodiment Construction
[0039] The invention provides an electric power remote meter reading system, which includes an electric meter arranged at the location of the electric power user for measuring the power consumption of the user; the electric meter includes an ordinary electric meter and an intelligent electric meter.
[0040] Ordinary meters are connected to building collectors through RS485 bus, and building collectors and smart meters communicate with concentrators through power line carrier. The concentrator realizes two-way data transmission with the meter reading central server through wireless communication; the wireless communication network is GSM network, GPRS network or CDMA network. Preferably, the meter reading central server is connected to multiple sets of concentrators through a wireless communication network, and each set of concentrators is connected to multiple building collectors and multiple smart meters. The preferred building collector includes an extended memory module bi...
