Electricity utilization information acquisition system

Abstract

The invention provides an electricity utilization information acquisition system which comprises a concentrator and first to N acquirers. Single-core plastic optical fibers serve as transmission channels among the concentrator and the acquirers, and the concentrator is connected with the acquirers in a closed-loop serial mode, so that closed-loop communication is achieved. As the concentrator and the acquirers are in closed-loop communication when data communication is performed, the concentrator can issue and acquire data commands through two paths (an anticlockwise direction and a clockwise direction form a single-core half-duplex channel), when a certain communication line breaks down, the acquirers can continue transmitting output data commands to a target acquirer and receive a feedback result through the other path, so that incapability of acquiring data due to breakdown of a certain point or disconnection is avoided, large reduction of failure rate and meter reading rate is avoided, and the reading efficiency of electric energy meters is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power data transmission, in particular to a power consumption information collection system. Background technique [0002] With the continuous development of data communication technology, it has become one of the common ways of collecting electricity information of residents in the prior art to automatically read the user's electricity consumption information through the electricity consumption information collection system. The structure of the conventional electricity consumption information collection system can be like figure 1 As shown in the figure, there is serial communication between each module (concentrator and collector) of the information collection system, and there is only one data transmission path. If the communication line between the collector and the collector or between the collector and the concentrator fails Or if a certain collector breaks down, the data of the electric ...

[0002] With the continuous development of data communication technology, it has become one of the general methods of collecting electricity information of residents in the prior art to automatically read the user's electricity consumption information through the electricity consumption information collection system. The structure of the conventional electricity consumption information collection system can be like figure 1 As shown in the figure, there is serial communication between each module (concentrator and collector) of the information collection system, and there is only one data transmission path. If the communication line between the collector and the collector or between the collector and the concentrator fails Or if a certain collector breaks down, the data of the electric energy meter at the lower end of the fault point will not be able to be collected, which will greatly affect the reading rate of the electric energy meter
