Abstract

The invention relates to bus electricity taking equipment and an electricity utilization control method and device thereof, a system and electrical equipment. The electricity utilization control method for the bus electricity taking equipment comprises the following steps of acquiring a current transmission line voltage, wherein the current transmission line voltage is the current voltage of two transmission lines between two end points at the bus electricity taking equipment side, and the two transmission lines are arranged between the bus electricity taking equipment and bus power supply equipment; comparing the current transmission line voltage with a preset voltage threshold value; and judging whether a first load and a second load are allowed to carry out electricity taking accordingto a comparison result of the current transmission line voltage and the preset voltage threshold value. According to the bus electricity taking equipment disclosed by the invention, the work cycle ofthe high-power load can be controlled, the high-power load can work only in the power supply period, and the low-power load work can be only kept in the communication period, so that a purpose of reducing the energy storage capacitance is achieved.

Description

technical field [0001] The present disclosure relates to the field of electrical appliance control, and in particular to a bus power-taking device, a power consumption control method, device and system thereof, and electrical equipment. Background technique [0002] Due to the advantages of long transmission distance, strong anti-interference ability and low cost, RS485 bus is widely used in industrial control, air conditioning and other fields. Since there are two independent power lines in the commonly used four-wire connection, there are more cable consumables, which increases the cost, and the order of wiring needs to be identified, which increases the difficulty of engineering wiring and the probability of errors. Contents of the invention [0003] The applicant found that the related technology adopts the two-core communication scheme, and the power supply and communication functions are completed through two-core wires, the cable consumables are halved, and the wiri...
