Device with slave control units replaceable and master-slave matching method thereof

Abstract

The invention discloses a device with slave control units replaceable and a plate number distribution method thereof. The device comprises a master control unit, the multiple slave control units and a peripheral circuit. The slave control units are electrically connected with the peripheral circuit through corresponding signal lines and comprise plate number generation modules. The plate number generation modules are used for actively generating plate numbers belonging to the slave control units according to signals of different levels, wherein the signals are collected by the corresponding signal lines. The plate number distribution method comprises the steps that the slave control units collect preset level signals output by the peripheral circuit corresponding to the signal lines, and according to the collected preset level signals and a certain protocols, the plate numbers of the slave control units are set automatically. Compared with the prior art, the method has the obvious advantages that the plate numbers are quickly set, few resources are occupied, different slave control units can be switched at will, and devices can be simply achieved.

Description

technical field [0001] The invention relates to a master-slave control device, in particular to a device with a replaceable slave control unit and a master-slave matching method thereof. Background technique [0002] At present, the BMS (power management system) slave control units that support the quick change mode require the slave control unit to have its own board number, so that the master control unit can identify the board number of the slave control unit, so as to manage and control the system. [0003] Under normal circumstances, the board number of the BMS slave control unit generally depends on the master control unit for allocation. When the master control unit is required for allocation, it is generally necessary for the slave control unit to provide some specific signals so that the master control unit can perform board numbering based on this information. Number allocation, this kind of information is generally unique to a certain slave control unit, that is t...

[0003] Under normal circumstances, the board number of the BMS slave control unit generally depends on the master control unit for allocation. When the master control unit is required for allocation, it is generally necessary for the slave control unit to provide some specific signals so that the master control unit can perform board numbering based on this information. Number allocation, this kind of information is generally unique to a certain slave control unit, that is to say, each slave control unit has its own unique information, and it is impossible to switch between slave control units arbitrarily
