During the use, the utility model discloses a control system can switch to different control mode according to the concrete demand of site work condition. The method specifically comprises the following steps: local mode, remote mode, and debug mode.
When the equipment is properly tested, the test enters a linkage test stage, and the method is suitable for a local mode. In the local mode, by operating the local cabinet button switch control circuit unit, the electric signal is input to the local information processing module, the local information processing module judges whether the input has interlocking relation with other opened signals, if no interlocking relation exists, the local information processing module outputs corresponding control signals to corresponding relays in the relay units, and after the relays are powered on, the circuit corresponding to the system power supply control circuit is electrified to realize the control of the switching value of the corresponding equipment unit (such as a valve) in the industrial field, when the corresponding equipment unit receives the control signal, the opening action is carried out, and after the opening is in place, a limit signal is generated, the feedback signals are transmitted to the corresponding relays through the signal wires, and the relays continue to transmit the feedback signals to the local information processing module after the corresponding indicator lamps are lightened by the action of the relays, so that the closed-loop control of the equipment is realized.
When the test enters a running test stage, an operator needs to complete control and monitoring of the equipment in a control room, and the mode is switched to a remote mode. In a remote mode, the control of a field device system is realized through a virtual control button in remote upper machine configuration software, a control signal of an upper machine is transmitted to a local information processing module through a Modbus TCP/IP protocol of a network cable through a switch, whether the input is in interlocking relation with other started signals is judged through the local information processing module, if no interlocking relation exists, the local information processing module outputs a control signal to a corresponding relay, after the relay is powered on to act, a circuit corresponding to a system power supply control circuit is powered on to realize the control of the switching value of a corresponding device unit in an industrial field, when the corresponding device unit receives the control signal, the starting action is carried out, after the starting is in place, a limit signal is generated and is transmitted to the corresponding relay through a signal wire, the relay acts to light a corresponding indicator lamp to indicate that the control is closed-loop completed, meanwhile, feedback signals can be transmitted back to the local information processing module, the local information processing module transmits signals to the upper computer and the touch screen after processing the signals, and meanwhile, the state quantities of the corresponding equipment units are displayed on a display and the touch screen of the upper computer, so that the remote closed-loop control of the field equipment system is realized.
When in the equipment initial debugging stage, because the industrial field operating mode is comparatively complicated, need carry out the debugging alone to each equipment, so need switch the mode to the debugging mode. Under the debugging mode, this moment through operation local rack button switch control circuit unit, the signal of telecommunication does not pass through local information processing module, but the direct transmission gets into corresponding relay, the signal of telecommunication can not pass through the processing of module like this, guarantee that the signal of telecommunication can both guarantee to convey the equipment unit that corresponds under any complicated operating mode condition, the equipment unit opens the back that targets in place, still can reach the relay and the local information processing module of corresponding pilot lamp with feedback signal back, when the uncontrollable damage appears in local information processing module, still can carry out the temporary control debugging to the equipment unit, but host computer and touch-sensitive screen can't show the state of equipment unit, only can judge equipment open mode through the pilot lamp, the closed-loop control of equipment has also been realized equally.
The data acquisition unit comprises a vacuum gauge, a recorder, an electronic instrument and the like and is used for acquiring data such as power supply voltage, current of a key equipment unit, vacuum degree and the like, and the acquired data can be transmitted to the upper computer. The upper computer stores the data information, transmits the data information to the local information processing module through the Modbus TCP/IP protocol of the network cable through the switch, and transmits the data to the touch screen.
Further, the 380V power supply is provided for the equipment, so that the system power supply control circuit is provided with a transformer unit, and 380V industrial power is integrated into 220V control power through the transformer unit.
Furthermore, only safe low-voltage power supply is needed for the local information processing module and the indicator light unit, so that the low-voltage power supply module is used for outputting a 24V power supply to carry out low-voltage power supply. Meanwhile, a high-voltage line and a low-voltage line are distinguished in the cabinet, so that the lines are independent and do not interfere with each other.
Furthermore, under the local mode and the debugging mode, the state quantity of the equipment unit can be transmitted to the upper computer through the communication unit, so that the state information of the upper computer and the state information of the local equipment unit are synchronous.
The invention has been described above by way of example, and it should be noted that any simple variants, modifications or other equivalent substitutions by a person skilled in the art without spending creative effort may fall within the scope of protection of the present invention without departing from the core of the present invention.
