Background technology
In the Control System Design of special purpose vehicle chassis electric CAN, when driver sends a left side (right side) rotaring signal, require that HMI upper left (right side) turns indicator light, anterior left (right side) Lamp for indicating change of drive direction, a left side, middle part (right side) Lamp for indicating change of drive direction, a left side, rear portion (right side) Lamp for indicating change of drive direction synchronous flashing; Driver requires when sending two glitch that HMI is upper left, right-hand rotation indicator light, anterior left and right Lamp for indicating change of drive direction, the left and right Lamp for indicating change of drive direction in middle part, the left and right Lamp for indicating change of drive direction synchronous flashing in rear portion.Because special purpose vehicle chassis electric CAN control system requires that in holotype chassis control system, each general purpose controller software and hardware is general, so realize above-mentioned each headlight synchronous flicker there is suitable difficulty.
Also there is same problem in the synchronous flashing system of high-rise roof simultaneously.
Also do not realize the universal method of multi-control object synchronization work at present.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of universal method realizing multi-control object synchronization and control.
A kind of universal method realizing multi-control object synchronization and control that the present invention proposes, the method arranges N number of controller to multi-control objective system, N >=2, and N number of controller adopts CAN communication to implement Synchronization Control, comprises the steps:
S1, wherein arbitrary controller, according to synchronous control accuracy requirement, arrange the Bus Speed of CAN, the priority of synchrodata frame message and message and send the cycle;
The controller selected in S2, S1 performs control logic, CAN synchronous control frame ID is set, load Synchronization Control Frame, and to needing the remaining controller realizing Synchronization Control to send Synchronization Control Frame in Preset Time, Synchronization Control Frame comprises remaining controller address signal and output end signal;
S3, each controller remaining receive the Synchronization Control Frame that S2 middle controller is arranged, and differentiate whether this controller performs Synchronization Control according to arbitrary controller address signal wherein;
S4, each controller remaining load output port signal and state thereof in Synchronization Control Frame according to S2 middle controller and implement the control to control object.
Preferably, in S2, Synchronization Control Frame has a variable N-1 amount controller and output port quantity.
Preferably, in S3, remaining controller arranges Synchronization Control and conventional control, and Synchronization Control and conventional control compatibility, when the arbitrary controller of each remainder receives Synchronization Control message and conventional control message simultaneously, described control port preferentially performs Synchronization Control message.
Preferably, the multi-control object of the method is the synchronous flashing system of the left and right turn signal lamp of vehicle chassis and two twinkle SM signal lamp.
Preferably, the multi-control object of the method is the synchronous flashing system at high-rise top.
