A device capable of replacing slave control units and its master-slave matching method

Abstract

The invention discloses a device capable of replacing slave control units and a board number allocation method thereof, which comprises a master control unit, several slave control units and peripheral circuits; Connecting, including a board number generation module, the board number generation module is used to actively generate the board number to which the slave control unit belongs according to signals of different levels collected from corresponding signal lines; including the following steps: the slave control unit collects peripheral The circuit corresponds to the preset output level signal of the signal line; according to the collected preset level signal, the board number setting of the slave control unit is independently set according to a certain protocol. Compared with the prior art, the present invention has significant improvements such as fast board number setting speed, less resource occupation, arbitrary switching between different slave control units, and simple equipment implementation.

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
