The whole system consists of third-level equipment, second-level channels and a system, of which:

  • Third-level equipment refers to electricity metering equipment, data acquisition equipment and master station equipment.

  • Second-level channels refers to the data channel between data acquisition devices and meters (downlink channels) and that between data acquisition devices and master station system (uplink channel).

  • A system means the meter reading system based on micro-power wireless ad hoc network.

 

 

  • Main Functions

    • Automatic Meter Reading (AMR): it saves periodic trips to each user’s home to read a meter, avoids disturbing the residents, increases the safety of residence in the community, and protects the privacy of residents in the community;

    • File Management: it maintains and manages basic indices of metering points and equipment, status of concentrator, data acquisition plan and operation log, among others;

    • Statistics and Analysis: the system classifies, analyzes and look over data of electricity meters in the form of sheets and graphics, including analysis of meter data of users in distribution transformer area and power line losses in distribution areas and substations, and statistics of power consumption of distribution areas, substations and users;

    • Statistical Forms Management: it saves and collects statistics of power consumption data, makes and prints forms;

    • Remote Electricity Cutoff and Supply: the system provides remote electricity cutoff and supply services where needed. When it detects any user defaulting electricity bills or use electricity illegally, the operator will send an instruction to cut off the electricity supply of the user. When the user meets the requirements for power supply, the operator will send an instruction to supply electricity for the user. (Note: this function needs support from a meter);

    • The system can send data through SMS, which is convenient for users to promptly know their consumption.

    • Automatic Frequency Modulation: with more than 10 channels for automatic frequency modulation, it is able to choose the best channel automatically according to the working environment;

    • Automatic Recovery: when any node in the network has any communication problems, the network will automatically reconstruct without affecting the communication of other nodes;

    • Data Encryption: the system is featured with AES-128 hardware encryption;

    • Automatic Networking: the whole network will automatically network and route without pre-setting, where needed;

    • Two-way and Real-time Communication: it is able to conduct remote and real-time meter reading; and actively reports according to the time on the meter;

    • Out-of-the-Box: when installing or removing the electricity meter, it shall automatically connect or disconnect the network, without setting.

     

  •  How to build the system?

    • Installing electronic energy meters in places for electricity metering that support micro-power/485 or other communication ways, wiring between the concentrator and RS485 meter, or communicating with micro-power radio frequency between the equipment;

    • Using the data concentrator installed in the electricity distribution room/distribution area/building to automatically collect data about power consumption from each meter through low-voltage power line carrier/485 BUS, and effectively managing the data;

    • Transmitting data from the concentrator to the master station of the micro-power wireless automatic meter reading system through GPRS/CDMA/TCP/IP or other network, in accordance with the meter reading plan of the system;

    • Testing the above-said equipment. The master station will release and share data in the form of WEB, report forms and database after analyzing and sorting out the data.
