Abstract

The present invention relates to the technical field of power bus communication, in particular to a method and device for transmitting power bus signals with one master and multiple slaves. The method includes: sending a communication control instruction to a slave; The level of return code current, the preset command includes online response, different value intervals and hand-raising arbitration; judge whether the slave machine has hand-raise arbitration or value range abnormality according to the level of return code current; if so, send specific data query Instructions to the slave that has a raised hand arbitration or an abnormal value interval, and receive the digital signal returned by the slave. The invention effectively solves the problems of low efficiency and reliability of power bus signal transmission and unstable power supply by combining analog and digital quantities in the process of returning information from the slave.

Description

technical field [0001] The invention relates to the technical field of power bus communication, in particular to a method and device for transmitting power bus signals with one master and multiple slaves. Background technique [0002] Currently, the one-master multi-slave power bus products with communication and power supply functions on the market are all digital signal transmissions, which transmit specific digital information in the form of waveforms. The advantage is that the transmitted values ​​are relatively accurate, and the disadvantage is that it takes a certain amount of time to complete. A pulse signal of 8 to 10 bits has low transmission efficiency. At the same time, high-frequency digital signal transmission is easily interfered by various external signals, which affects the accuracy and reliability of information transmission, while low-frequency digital signals are guaranteed. On the basis of reliability, the balance and stability of the power bus power supp...
