Embodiment Construction
[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the industrial equipment control method, system, and storage device of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0046] For the monitoring of hardware status, use the observer mode, and the observer includes other classes or modules of this program, as well as the host computer. The specific implementation method is: when starting the lower computer software, the lower computer software will read the current state of the hardware as the initial state. At the same time, the lower-level machine will notify all observers of the read status in turn. When the state of the device changes again, the current state of the device is notified to all observers in turn. When a state or value change occurs on a concerned channel, all observers are notified serially, that is, e...

The invention belongs to the technical field of computers / industrial control, and relates to an industrial equipment control method and system, and storage equipment. The industrial equipment controlmethod comprises the following steps that: obtaining a notification requirement of a lower computer for an upper computer; adding a lower computer thread, and configuring the lower computer thread into a communication thread of the lower computer for the upper computer; adding a task package, packaging the to-be-notified contents of processing contents in a callback function of the upper computerin the task package; sending the task package to the lower computer thread to be processed, and sending the task package to the upper computer by the lower computer thread; and notifying all observers of other to-be-notified contents except processing contents in the callback function of the upper computer by the lower computer according to a serial sequence. By use of the method, an individual thread is created for the upper computer to carry out the notice callback of the upper computer and the lower computer, various aspects of factors that the operation of the lower computer is restrictedby the processing of the upper computer for the callback function, a network is unsmooth and the like can be avoided, and the stability of technology execution time is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of computer / industrial control, and in particular relates to an industrial equipment control method, a system thereof, and a storage device. Background technique [0002] In the field of equipment process control, the control of equipment includes three parts. Such as figure 1 In the organizational structure of equipment control shown, the dispatcher at the factory is responsible for assigning tasks to all machines or equipment in the factory, and the upper computer (such as the cluster control system CTCI) is responsible for scheduling the actions of the entire machine and providing a human-computer interface. On the one hand Display the status of each device on the machine, on the one hand, send the control command from the person or factory to the lower computer; the lower computer (including the process chamber control interface PMCI and the transmission module control interface TMCI) is responsible for...
