First, in step S401 , the group controller obtains a control instruction, and the control instruction may be a control instruction to be transmitted by broadcast, or may be a control instruction not to be transmitted by broadcast. Next, in step S402, the group controller item database acquires verification information, so as to verify whether the control command is a safe control command through the verification information, and if the verification is passed, then execute step S403, Otherwise, the transmission of the control command is discarded, and the process returns to step S401, so that the group controller obtains another control command.

In step S403, the group controller transmits the control instruction to the module controllers of each group. In step S404, the group controller determines whether the control command is a broadcast control command, and if not, executes step S410. In step S410, only the modular controller of the modular unit corresponding to the destination of the control command will use the standard channel to transmit the control command. The control command is transmitted through the standard channel, the first module unit is transmitted to the second module unit, the second module unit is transmitted to the third module unit, ..., and the x-1th module unit Transfer to the xth module unit, where the xth module unit is the module unit corresponding to the destination of the control command. Therefore, in step S411, the micro control unit will communicate with the module controller, so that the module controller can determine whether the control command has been delivered to the module unit corresponding to the destination of the control command, if not, continue to execute step S410, if the control After the instruction has been delivered to the module unit corresponding to the destination of the control instruction, return to step S401 to make the group controller obtain another control instruction.

In step S405, the module controller tries to transmit the command through the broadcast channel. Next, in step S406, the module controller communicates with the micro control unit to determine whether there is a disconnected broadcast channel. The broadcast channel transmits the control command to each module unit in the group, and then returns to step S401, so that the group controller obtains another control command.

If there is a need to transfer across modules, it means that the broadcast channel between two adjacent module units is disconnected. At this time, in step S407, between the two adjacent module units where the broadcast channel is disconnected The standard channel transfers control commands. Then, in step S408, it is judged whether After transmitting the control command to each modular unit in the group, if not, execute step S409; if yes, return to step S401, so that the group controller obtains another control command. In step S409, it is judged whether the next broadcast channel after a plurality of adjacent module units in which the broadcast channel is disconnected is unblocked, if the next broadcast channel is unobstructed and there is no disconnection, then the control instruction is changed to the next broadcast channel for transmission, otherwise, then Back to step S408, continue to use the standard channel to transmit the control instruction.

Based on the above, the module system, module unit and broadcasting method provided by the present invention can support broadcasting, transmit control commands at a faster transmission speed, and the transmission path can be flexibly changed due to conditions, so even if the broadcasting channel has a condition , can still effectively and quickly transmit control instructions to each module unit. Furthermore, the above-mentioned module system can be a blessing lamp system or a processing system, therefore, the present invention can be widely used in various fields and has great economic value.
