the upper computer 1 is used for transmitting an industrial water system switching instruction of a user to the dual-redundancy controller 3 through the network switch 2 so as to control the multiple systems to be switched through the industrial water treatment circulation; in some preferred embodiments, the upper computer 1 is further configured to receive a status feedback signal of the PLC cabinet 4, and when a problem occurs in the status of the PLC cabinet 4, automatically send specific PLC cabinet 4 information to the upper computer 1, and the upper computer 1 automatically sends a switching signal according to the PLC information, so that the PLC cabinet 4 in a normal status operates.
The network switch 2 is used for communicating the upper computer 1 and the dual-redundancy controller 3 and wirelessly sending an industrial water system switching instruction of a user to the dual-redundancy controller 3; in this embodiment, the network switch 2 communicates the upper computer 1 with the dual redundant controller 3 through ethernet.
The dual-redundancy controller 3 is used for receiving an industrial water system switching instruction of a user and sending a corresponding control instruction to the PLC cabinet 4 according to the instruction of the user so that the PLC cabinet 4 works according to a preset instruction; in particular, as manufacturing competition increases, manufacturers are increasingly pursuing reliability of production equipment, particularly equipment that controls critical production processes, often requiring redundant configurations. Most redundant systems based on programmable controllers employ two sets of CPU processor modules, one as the master processor and the other as the slave processor. Under normal conditions, the main processor executes the program to control the I/O equipment, and the slave processor continuously monitors the state of the main processor. If the main processor fails, the auxiliary processor immediately takes over the control of the I/O and continues to execute programs, thereby realizing the redundant control of the system.
Redundancy control is a control mode that adopts a mode of a certain or multiple-quantity of equipment or components to form a control system. When a certain device or component is damaged due to failure, the device or component can be mutually switched to be used as a backup device or component through a hard mode, a software mode or a manual mode to replace the device or component damaged due to failure, so that the normal work of the system is kept, and the shutdown loss of the control device due to accidents is reduced to the minimum.
And the PLC cabinet 4 is used for receiving the control instruction of the dual-redundancy controller 3, working according to the control instruction and controlling the corresponding regulating valve 5.
In the present embodiment, there are preferably 4 PLC cabinets 4, each controlling a corresponding water treatment subsystem in the industrial water treatment circulation control system. Specifically, a first PLC cabinet 4 is used for controlling a clean circulating water treatment subsystem, a second PLC cabinet 4 is used for controlling a filtered water treatment subsystem, a third PLC cabinet 4 is used for controlling an accident water treatment subsystem, and a fourth PLC cabinet 4 is used for controlling an acid-base wastewater treatment subsystem.
And the regulating valve 5 is used for receiving the control of the PLC cabinet 4, realizing the on-off of the regulating valve 5 corresponding to the control instruction and achieving the aim of controlling the switching of multiple systems by the industrial water treatment circulation. In this embodiment, the regulating valves 5 are multiple according to actual control requirements, the regulating valves 5 are respectively installed in a multi-switching system for controlling key nodes, and the industrial water treatment cycle control is realized through the on-off of the regulating valves 5.
The multi-switching system for industrial water treatment cycle control disclosed by the embodiment comprises: host computer, network switch, dual redundant controller, PLC cabinet, governing valve. When the main PLC stops running due to a fault, the standby PLC can be automatically switched to run without disturbance. The whole operation regulation of the system is not influenced, and the production operation continuity is ensured. When one set of the workstations stops operating due to faults, the standby workstations can be switched to operate automatically without disturbance. The monitoring regulation and control of the system are not influenced, the database data can be synchronously backed up into the server, and the production monitoring real-time performance is ensured. The communication station in the system adopts a double DP communication cable and module scheme, so that when the communication station has an abnormal fault, the normal communication of other stations is not influenced, the fault station is isolated, and the communication independence of each station is kept. The PLC component module is designed by adopting redundant hardware, when any set of fault occurs, the fault hardware can be replaced on line, and the system does not need to be shut down and is easy to maintain. The method has good practical value for the application field of the control system with special operation requirements.
