According to the intelligent industrial control instrument management system and the control method thereof provided by the embodiment of the invention, the first processing equipment connected with at least one industrial control instrument and the second processing equipment connected with the first processing equipment are arranged, and the second processing equipment is controlled to process a dormant state or an awakening state when the first processing equipment is in different working states, so that the cost is saved, and meanwhile, the intelligent industrial control instrument management system and the control method thereof can be taken into consideration and suitable for scenes needing to process and analyze a large amount of data.
As shown in FIG. 2, preferably, in some embodiments of the present invention, the industrial control instrument 100 includes a flow control device 110 that creates a pressure differential across a fluid flow path; a pressure measuring device 120 for measuring pressure values at both ends of the flow control device; the first communication module 130 is used for transmitting the pressure value to the first processing device 200 and receiving a flow value returned by the first processing device 200; and a dashboard 140 for displaying the flow value. The traditional intelligent industrial control instrument is generally independently provided with processing devices such as a PLC (programmable logic controller) for data processing and field control, and the realization of the remote control function is connected with a communication module through the processing devices such as the PLC and then connected with a remote end. By adopting the technical scheme of the embodiment, a processing device with a data processing and storage unit is not required to be arranged on each industrial control instrument, and the acquired data is delivered to the first processing equipment at the rear end in real time or delivered to the second processing equipment through the first processing equipment to be processed and then returned to the instrument panel to be displayed, so that the structure of the industrial control instrument is simpler, and the production cost of the equipment is reduced.
Preferably, in some embodiments of the present invention, the flow control device 110 includes a throttle plate, a through hole for allowing the liquid to pass through is formed in the throttle plate, the flow control device 110 is connected to the first communication module, and the through hole is controlled to be enlarged or reduced according to a control command of the first processing apparatus or the second processing apparatus, and a maximum value of a diameter of the through hole is smaller than the target pipe inner diameter. When the industrial control instruments such as the pressure transmitter are used for measuring flow, the pressure difference can correspondingly change greatly when the flow velocity is changed greatly, and the pressure transmitter with the corresponding measuring range is required to be designed for measuring different flow sizes. By adopting the technical scheme of the embodiment of the invention, the pressure difference at two sides of the throttle plate can be adjusted by controlling the size of the through hole, so that the measuring range of the pressure measuring device 120 is wider, and meanwhile, the calculation amount of calibration or compensation caused by the change of the measuring range is reduced, thereby reducing the calculation pressure of a processor.
In the technical solution of the embodiment of the present invention, the first communication module 130 includes a data acquisition interface, the data acquisition interface is connected to the pressure measurement device 120, and the first communication module 130 receives real-time measurement data of the pressure measurement device 120 through the data acquisition interface and sends the real-time measurement data to the first processing device 200.

Further, in some embodiments of the present invention, the industrial control instrument 100 further includes a temperature sensor connected to the first communication module 130 for measuring a temperature of the liquid in the target pipeline. In the technical solution provided in the embodiment of the present invention, the temperature sensor obtains the temperature of the liquid in the target pipeline, the first communication module 130 sends the temperature value and the measured pressure value to the first processor 200, and the first processor 200 calibrates the measured pressure value based on the temperature value, so that the intelligent industrial control instrument management system has wider applicability and the measurement result is more accurate.

By adopting the technical scheme of the embodiment, the system can operate in a low power consumption state, and compared with the traditional technical scheme of arranging a processing device on each industrial control instrument, the system has the obvious energy-saving advantage.
In other embodiments of the present invention, the first processing device 200 may further include an alarm module 260 and a touch display module 270. The alarm module 260 is configured to issue an alarm to remind a worker when any one of the industrial control instruments 100 is abnormal. The touch display module 270 is used for displaying the working state of the industrial control instrument 100 and inputting some simple control instructions.

The staff can input control instructions through the touch display module to control the power switch of each industrial control instrument 100, the switch of the measurement pipeline valve and/or the size of the throttle plate through hole.

Preferably, when the second processing device is in the dormant state, the data of the industrial control instrument is only displayed in real time through the touch display module and/or the instrument panel and is not stored permanently, and after the data is used up, the data is periodically destroyed according to the memory use state of the first processing device to vacate a space for subsequent data use.

In some embodiments of the present invention, the first processing module is further configured to wake up the second processing device when the industrial control instrument is abnormal, and send abnormal data to the second processing device for storage and analysis. The abnormal data includes rapid increase or decrease of the pressure value in a short time or continuous maintenance outside a preset range. For example, via clogging, uncontrollable via size, electrode damage or deformation, power supply anomalies, communication interruptions, etc.
