Double-channel multifunctional electric energy information collector and communication method thereof

Abstract

The invention relates to a double-channel multifunctional electric energy information collector and a communication method thereof. The double-channel multifunctional electric energy information collector comprises an RS485 channel meter reading module, an MCU module, a power carrier module, a wireless module and a memory, wherein the RS485 channel meter reading module is connected with the MCU module; the wireless module having the functions of wireless information transmission and wireless information reception and the power carrier module are both connected with the MCU module; the RS485 channel meter reading module collects data and respectively collects, processes and stores signals output by an electric energy meter or electricity utilization data signals; the electricity utilization information collected by the RS485 channel meter reading module is exchanged with the MCU module; the MCU module, the power carrier module and the wireless module form double channels; and the power carrier module and the wireless module are set as a main channel and a standby channel. The MCU module firstly selects the main channel to communicate with other collectors; when the main channel can not be used for communication successfully, data transmission is carried out with other collectors through the standby channel; and when the main channel recovers communication, the main channel is used for communication again.

Problems solved by technology

But each has its own disadvantages: the narrowband carrier type has small attenuation and long transmission distance, but the rate is low, and it is difficult to realize dynamic routing, so the above-mentioned meter reading success rate requirements cannot be achieved.

The power carrier is mainly affected by time. Due to the uncertainty of the load, the interference to the power grid is different in different time periods. Therefore, at different times, the power carrier communication effect is different, sometimes it is connected, sometimes it is not; wireless data The transmission is mainly affected by the geographical environment. Blocking and shielding will seriously affect the effect of data communication. On-site construction is very difficult
