Remote communication type micro-power grid electricity meter

Abstract

The invention discloses a remote communication type micro-power grid electricity meter, which comprises a controller and the following elements in connection with the controller: an acquisition device, a communication device and an interface device. The controller comprises a control chip and a command saving device in connection with the control chip. The acquisition device comprises a signal acquisition device connected with the controller and a display device arranged on the surface of the electricity meter body. The communication module comprises an electric line carrier communication module, a radio frequency module and a radio frequency matching circuit. The interface device comprises a load interface and an energy saving interface. The electricity meter of the invention can achieve comprehensive functions through a remote manner on one hand; and through the interface device on the other hand, the seamless docking can be realized between the electricity meter and the direct current power grid and the direct current bus. Due to the realization of the double network mixing of the intelligent electricity meter and the bi-directional communications, the remote communication to the intelligent electricity meter by a user as well as the electricity consuming information check become possible, realizing the double effects of remote check and docking management. Therefore, the electricity meter is worth wide promotion and application.

Description

technical field [0001] The invention relates to the technical field of smart electric meters, in particular to a remote communication microgrid electric energy meter. Background technique [0002] In recent years, with the widespread application of renewable energy, the cost of energy storage equipment has continued to decrease, and various forms of DC microgrids have emerged. Driven by power electronics technology and energy storage technology, DC microgrid has developed rapidly, and will become the main power supply structure for remote mountain villages and future households due to its advantages of easy control, high reliability, and low loss. Distributed DC micro-grid management of power consumption has become a problem that needs to be solved in the power industry. [0003] The current electricity consumption management has generally entered the era of intelligence, and the use of intelligent electricity management systems and smart meters continues to increase. On th...

[0007] However, through a comprehensive comparison, the wireless near-field communication network involved in the above-mentioned device or method is easily affected by the home building pattern and the natural environment, and the communication efficiency is restricted. Moreover, the pure power line communication method is also easily affected by factors such as power conditions, and the communication is successful. The rate is not high, which requires a remote communication method that avoids near-field wireless communication and power line communication at the same time.
