Embodiment Construction

[0014] An embodiment of a general method for realizing synchronous control of multiple control objects in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] refer to figure 1 , the general method that realizes synchronous control of many control objects provided by the present invention, master controller and some slave controllers are set to multi-control object system, master, slave controller adopt CAN bus communication to implement synchronous control, this method comprises the following steps:

[0016] Step 1, the main controller sets the bus rate of the CAN bus, the priority of the synchronization data frame message and the message sending cycle according to the synchronization control accuracy requirements;

[0017] Step 2, the master controller executes the control logic, sets the CAN synchronous control frame ID, loads the synchronous control data frame, and regularly sends the synchronous control data frame...

Abstract

The invention provides a general method for realizing synchronous control of multiple control objects, including the steps of the main controller setting the bus rate of the CAN bus, the priority of the synchronous data frame message and the message sending cycle, and the main controller setting the CAN synchronous control Frame ID, loading synchronous control data frame, the steps of sending synchronous control data frame to the slave controller regularly, each slave controller receives the synchronous control data frame, the step of judging whether the controller executes synchronous control and each slave controller implements pair control The steps of the object's control. The advantage of the general method for realizing synchronous control of multiple control objects in the present invention is that: since the master and slave controllers are set, the synchronous work of multiple control objects controlled by the multi-controller is realized, and each controller does not need special design or parameter setting. The method can be used in other similar occasions requiring synchronous control functions, and is simple and universal, with good effect and strong versatility.

Description

technical field [0001] The invention relates to a control method, in particular to a general method for realizing synchronous control of multiple control objects. Background technique [0002] In the design of the electric CAN bus control system of the special vehicle chassis, when the driver sends a left (right) turn signal, the HMI is required to display the left (right) turn indicator light, the front left (right) turn light, and the middle left (right) turn signal. lights and the rear left (right) turn lights flash synchronously; when the driver sends out a double flash signal, the driver requires the HMI to display the left and right turn indicators, the front left and right turn lights, the middle left and right turn lights, and the rear The left and right turn lights flash synchronously. Since the electrical CAN bus control system of the special vehicle chassis requires that the software and hardware of all general controllers in the chassis control system of all mod...
