Embodiment 1
[0034] This embodiment provides a mimetic arbitration method based on a mixed data type industrial protocol, which is applied to a mimetic industrial control system with a heterogeneous multi-controller architecture, such as figure 1 As shown, the industrial control system includes a mimetic arbiter, multiple heterogeneous controllers and multiple IO devices. As the output agent of multiple heterogeneous controllers, the mimicry arbitrator judges credible IO device control data and sends it to the IO device, and cleans and restores the controller in the abnormal state according to the result of the mimicry judgment, among which the heterogeneous control The controller includes multiple processors with different architectures (such as: A7, M7, Godson, etc.), and the corresponding industrial control application program runs on the heterogeneous controller; the mimic arbitrator includes a mimic judgment module, a cleaning scheduling module, and multiple data communication interfac...
Embodiment 2
[0064] The embodiment of the present invention also provides a mimetic arbitration method based on a mixed data type industrial protocol, which is applied in an industrial control system, and the industrial control system includes a mimetic arbitrator and a device connected to the M heterogeneous controllers and H IO devices, of which M is a positive integer greater than 3, H is a positive integer greater than 0, the method includes:
[0065] Step (1), in each control cycle each master controller unit will H The control data of each IO device is calculated and packaged separately according to the digital quantity and the analog quantity, and the range of each IO device needs to be unified when calculating the analog quantity;
[0066] Step (2), each main controller unit packs the IO device control data that has been packaged according to the communication interface protocol between the main controller unit and the arbiter, and then sends it to the arbiter;
[0067] Step (3...
Embodiment 3
[0075] refer to Figure 4 , the present embodiment provides a mimetic arbiter based on the mixed data type industrial protocol, including:
[0076] The receiving module 91 is used to receive the IO device control data sent by each main controller unit, and the said IO device control data is controlled by each main controller unit in each control cycle to the control data of multiple IO devices according to the digital quantity and the analog quantity. It is calculated separately and packaged, and when calculating the analog quantity, it is necessary to unify the range of each IO device;
[0077] The verification module 92 is used to analyze and verify the communication protocol of the IO device control data, obtain the main controller unit with abnormal communication and the main controller unit with normal communication, and mark the main controller unit with abnormal communication ;
[0078] Scheduling module 93, is used for utilizing the screening mechanism of each contro...
