Embodiment Construction

[0037] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the described examples.

[0038] like figure 1 As shown, a slave controller configuration system includes a host computer 1 and four slave controllers 2, each slave controller 2 is connected to the host computer 1 through a CAN bus, specifically through CANL and CANH signal lines; each Each slave controller 2 includes an input interface IN and an output interface OUT, and four slave controllers 2 pass the input interface IN and the output interface OUT such as figure 1 The sequence shown is cascaded.

[0039] Wherein, the host computer 1 is used to send the first command to the slave controller 2 through the CAN bus; the slave controller 2 is used to generate a random number after receiving the first command, and use the random number as a message ID; the slave controller 2 is also used to send the first response message to the host computer 1;...

Abstract

The invention discloses a configuration method and a configuration system for a slave controller in a system. The method includes: S1. The upper computer sends a first command to the slave controller; S2. The slave controller generates a random number as a message ID; Respond to the message to the host computer; S3, the host computer judges whether all the message IDs are completely different, if so, execute step S4; S4, select the message ID to be configured; send the second command; S5, the slave control to be configured The device sends a second response message to the upper computer, and sends a trigger signal, and the trigger signal is used to control all slave controllers of the lower level to send trigger signals step by step; S6, the upper computer counts the number N of the second response messages ; Obtain the preset ID of the slave controller whose position is N; S7. The slave controller to be configured updates the message ID to the preset ID. The invention provides a brand-new automatic configuration mode of the slave controller in the system.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a configuration method and a configuration system of a slave controller in a system. Background technique [0002] With the development of new energy vehicle technology and national policy support, the production of electric vehicles has increased year by year. The application of battery management system, one of the three electric systems, is becoming more and more extensive. The battery management system generally adopts the structure of a master controller plus several slave controllers. The master controller is mainly used for logic control, and the slave controller is mainly used to collect the temperature and voltage information of the single battery and report it to the master controller. For manufacturers that provide battery management systems, they will face different battery structures and compositions, and the corresponding battery management systems are al...
