Abstract

The present invention relates to a power management method, device and multi-connection system. The method includes: collecting the electrical parameter value of the output terminal of the wire controller; and comparing the electrical parameter value with the first set value and the second set value respectively , to obtain a comparison result; wherein, the first set value is smaller than the second set value; according to the comparison result, generate power supply control information of the power supply corresponding to the wire controller; according to the power supply control information Controlling the power supply voltage input from the power supply to the wire controller, so that the wire controller outputs electrical parameters that match the load corresponding to the wire controller, realizing dynamic adjustment of the power supply to the wire controller The power supply voltage input by the wire controller. By adopting the technical solution of the present invention, under the condition of long-distance power carrier communication, the load corresponding to the wire controller can be normally supplied with power.

Description

technical field [0001] The present invention relates to the technical field of power carrier communication, in particular to a power management method, device and multi-connection system. Background technique [0002] In a commercial multi-connection system, in order to facilitate installation and save costs, the wire controller in the multi-connection system and the indoor unit main board of the indoor unit usually use two-core wires for communication. That is to use the power carrier communication method to load the communication signal to the power supply for transmission, so that communication and power supply coexist. [0003] However, the communication distance is often limited by the diameter and material of the communication line. The longer the communication line, the greater the resistance on the line, and the greater the divided voltage. The obtained voltage is relatively low. As the communication distance increases, the voltage of the wire controller will be low...
