Power consumer electricity information collecting system and collecting method thereof

Abstract

The invention discloses a power consumer electricity information collecting system. The power consumer electricity information collecting system comprises a collecting terminal (1), multiple electricity meters (2) and multiple indoor display units (3) of which the number is the same as that of the electricity meters (2), and the electricity meters (2) and the indoor display units (3) are connected with the collecting terminal (1) through a power line (4) used for building a same communication network. A collecting method of the power consumer electricity information collecting system comprises the following steps that 1, all the electricity meters and all the indoor display units request registering to the collecting terminal; 2, the collecting terminal regularly issues communication addresses of the unpaired electricity meters to all the indoor display units; 3, the indoor display units acquire the electricity meter communication addresses of the unpaired electricity meters in the network from the collecting terminal; 4, a user selects the communication address of the electricity meter to be paired from the indoor display units; 5, the indoor display units display electricity information of the electricity meter. According to the power consumer electricity information collecting system, the communication crosstalk phenomenon can be prevented from occurring between the indoor display units and the unpaired electricity meters.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a power user information collection system and a collection method thereof.

[0002] At present, the electricity consumption information collection system of power users mainly includes collection terminals (5), several electric meters (6) and several indoor display units (7) with the same number as electric meters (6). The specific connection structure is as follows: figure 1 As shown, the acquisition terminal (5), the electric meter (6) and the indoor display unit (7) are respectively provided with an acquisition terminal communication module (51), an electric meter communication module (61) and an indoor display unit communication module (71), The several electric meters (6) are connected to the collection terminal (5) through the first power line (8), and the several indoor display units (7) are respectively connected to the several electric meters (6) through the independent second electric power line (9). One-to-one corresponding connection, the collection terminal (5) and the connected electric meter (6) form a network, the electric meter (6) is managed by the collection terminal (5), the indoor display unit (7) is not connected to the network, and the indoor display unit (7 ) and the electric meter (6) are connected by P2P, and the connection between the collection terminal (5) and the electric meter (6), between the electric meter (6) and the indoor display unit (7) is carried out by means of power line carrier communication, and the modulation method is FSK modulation ; Since the indoor display unit (7) is not connected to the network, the problem of communication crosstalk is likely to occur between the non-corresponding indoor display unit (7) and the electric meter (6), that is, the indoor display unit (7) is easy to display and the indoor display unit (7) The power consumption information of the electricity meter (6) does not correspond, resulting in display errors, and because the carrier modulation mode of the above-mentioned power user power consumption information collection system is FSK modulation, it has the disadvantages of large occupied bandwidth and slow communication speed
