Embodiment Construction
[0025] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
[0026] Such as figure 1 As shown, the smart energy meters with integrated remote communication modules have the ability of virtual gateways and parent meters. According to different remote communication modules, there are many application methods. The smart energy meter integrated with GPRS module is directly connected to the AMI system. As a master meter, several sub-meters are connected through the bus. The complete physical link is:
[0027] AMI system GPRS module master meter bus child meter
[0028] The smart energy meter is connected to the AMI system in the above general way to ensure that the entire physical link la...

The invention provides a mother-child topology structure of intelligent ammeterselectric energy meter, and a method. According to the method, the multiple intelligent ammeterselectric energy meter ina physical layer share one remote communication module, cascade of remote communication channels is realized by combining a DLMS protocol layer virtual gateway and an automatic registration technology, field installation and filing processes are simplified, the hardware cost of the communication channels in an AMI system is lowered, and the remote communication distance of the intelligent ammeterselectric energy meter is extended. The problems of the high hardware cost of the communication channels in the AMI system and the short communication distance are solved, multi-level management of communication is realized, the hardware cost of the communication channels in the AMI system achieves the ultimate, and then informationization and automation of the AMI system are improved.
Description
technical field [0001] The invention relates to the field of electric energy metering and meter reading of electric energy meters, and specifically relates to a parent-child topology structure method of an intelligent electric energy meter, which realizes multi-level communication management and makes the hardware cost of the communication channel of the AMI system extremely low. Background technique [0002] With the continuous development of our country's economy, and the continuous progress of science and technology towards informatization and automation, the demand for power resources is also increasing rapidly, and the domestic power industry has achieved unprecedented development. Most of the power facilities in the power system are scattered, and the number of users has increased sharply. Accurate and timely settlement of the purchase and sale of electricity is required, which brings great distress to the management of the power system. The manual on-site maintenance ...
