and receiving the execution result fed back by the station control device, and feeding back the execution result to the central control device.
Specifically, the water hammer programmable logic control device sends an instruction to the station control device, the station control device executes a built-in program according to the received instruction, after the program is executed, the station control device feeds back an execution result to the water hammer programmable logic controller, and the water hammer programmable logic controller feeds back the received execution result of the station control device to the central control device. In one example, according to the execution result fed back by the water hammer programmable logic controller, the central control device uploads the relevant information to the display so that a dispatcher can master the running process of the system in real time and timely find out a problem to make adjustment.
In the embodiment of the present application, in the case that the instruction is a start-dispatch transmission instruction, the preselected data includes: the type of the oil products to be separately conveyed, the separate conveying amount and the number of the separate conveying paths;
in the case where the instruction is an injection enable instruction, the preselected data includes: the type of injected oil, the injection amount and the number of injection starting paths.
Before starting and separating transmission, a dispatcher needs to perform starting and separating transmission preselection operation through a central control device, and the central control device sends acquired preselection data and starting and separating transmission instructions to a water hammer programmable logic controller; the preselection data of the division transmission comprises the type of the oil products to be transmitted, the division transmission amount and the division transmission path number. In one example, taking the western finished oil pipeline as an example, the number of start-branch transmission lines of the western finished oil pipeline is 4, namely 0# Chai Youlu, -10# Chai Youlu, 92# diesel way and 95# diesel way. Before injection starting, a dispatcher needs to perform injection starting preselection operation through a central control device, and the central control device sends acquired preselection data and an injection starting instruction to a water hammer programmable logic controller; the pre-selected data of the injection starting are the type of the injected oil product, the injection amount and the number of injection starting paths.
