[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] At least one embodiment of the present application provides a digital graphic display handheld operator, which is a display device for a process operator of a regulation loop. Figure 1 and Figure 3 The digital graphic display hand operator includes a display unit 1 and a control unit 2. The control unit 2 includes a data acquisition system 21 and a data processing system 22. The data acquisition system 21 is connected in communication with a distributed control system (DCS system for short) 100 and a data processing system 22, and is used to receive signals transmitted by the distributed control system 100 and transmit them to the display unit 1 with a digital graphic display function for display after being processed by the data processing system 22. The data processing system 22 is electrically connected to the display unit 1, and is used to receive parameters set by the operator on the display unit 1 and output them to the distributed control system 100 through the data acquisition system 21 after processing, so as to be output to the display screen via the distributed control system 100 for display.

[0030] For example, the display screen may be a liquid crystal display screen or other types of display screens.

[0031] The digital graphic display hand operator provided in the embodiment of the present application integrates display and operation, and has a digital graphic display function, which can replace the mechanical hand operator represented by the moving coil pointer, and greatly improves the display accuracy, response time, and operation flexibility. In addition, the digital graphic display hand operator can be used in conjunction with the distributed control system 100, has a light volume, flexible operation, and accurate data, realizes the parameter adjustment and function control of the on-site equipment, and develops in the direction of digitalization, intelligence, multi-function, and integration.

[0032] In at least one embodiment of the present application, reference Figure 3The data processing system 22 includes a microcontroller unit (MCU) 221. The display unit 1 includes a display and key system 11. The display and key system 11 includes a display module 111. The microprocessor 221 is connected to the data acquisition system 21 for communication, and is used to analyze and process the signal transmitted by the data acquisition system 21 and send it to the display module 111 for display. In this way, by setting the data processing system 22 to adopt the microprocessor 221 technology, the data transmission and processing speed is better, the real-time performance is stronger, and the reliability is higher.

[0033] For example, refer to Figure 3 The microprocessor 221 may be provided with a transmitter (TX), and the display module 111 may be provided with a receiver (RX), so that the microprocessor 221 can transmit data to the display module 111 in a TX / RX manner.

[0034] In some embodiments, the content displayed by the display module 111 is displayed in the form of a bar graph superimposed with numbers. Thus, by setting the display module 111 to adopt a dynamic bar graph display technology, the content displayed by the display module 111 is displayed in real time and realistically in the form of a bar graph superimposed with numbers, with a friendly human-computer interface.

[0035] For example, the display module 111 may also use an IPS full-viewing angle liquid crystal screen, which enables fast response speed, accurate colors, excellent dynamic images, and also makes the human-computer interface (liquid crystal display) more intuitive.

[0036] refer to Figure 5 The display module 111 displays the real-time bar graph of the measured value. Figure 1 a. Real-time data of measured value 1b. Real-time bar of output value Figure 1 c. Output value real-time data 1d. Local setting value real-time bar Figure 1 e and local setpoint real-time data 1f.

[0037] In at least one embodiment of the present application, reference Figure 3 , the data processing system 22 also includes a drive control module 222. The display and key system 11 also includes an operation key module 112. The operation key module 112 includes a local setting increase / decrease key 112a. The drive control module 222 is used to receive the contact signal output by the local setting increase / decrease key 112a and transmit it to the microprocessor 221. The microprocessor 221 is used to accumulate and calculate the current local setting value to obtain a final value, and output the final value to the distributed control system 100 through the data acquisition system 21, so as to be output to the display screen via the distributed control system 100 for display.

[0038] It should be noted that the final value is an analog output signal of the digital graphic display handheld operator. The local setting increase / decrease button 112a is used to adjust the local setting value of the loop.

[0039] In at least one embodiment of the present application, reference Figure 3 The control unit 2 further includes a manual operation system 23 hard-wired to the distributed control system 100. The manual operation system 23 includes a manual operation module.

[0040] In at least one embodiment of the present application, reference Figure 4 The operation button module 112 also includes a manual increase / decrease button 112b. The manual increase / decrease button 112b includes a fast increase button, a fast decrease button, a slow increase button, and a slow decrease button. The contact signals of the fast increase button, the fast decrease button, the slow increase button, and the slow decrease button are given four different voltage level signals by the voltage divider circuit of the manual operation module and transmitted to the distributed control system 100. For example, the voltage level signal corresponding to the fast increase button is -8.3V, the voltage level signal corresponding to the fast decrease button is +8.3V, the voltage level signal corresponding to the slow increase button is -0.8V, and the voltage level signal corresponding to the slow decrease button is +0.8V.

[0041] In at least one embodiment of the present application, reference Figure 3 The control unit 2 also includes a manual operating system 23 hard-wired to the distributed control system 100. The manual operating system 23 includes a state switching module. The operation button module 112 also includes a manual button and an automatic button. The contact signals of the manual button and the automatic button are transmitted to the distributed control system 100 by the state switching module. In this way, the contact signals of the manual button and the automatic button are converted into state command signals by the state switching module and directly transmitted to the DCS system without being processed by the microprocessor 221, thereby ensuring the reliability of the signal.

[0042] It should be noted that the state switching module may default to the manual state after power-on.

[0043] For example, after the automatic button is pressed, the contact signal of the automatic button is transmitted to the DCS system via the state switching module outputting an 11V voltage signal, and lighting up the automatic button lamp A. After the manual button is pressed, the contact signal of the manual button is transmitted to the DCS system via the state switching module outputting a -15V voltage signal, and lighting up the manual button lamp M. The state command signal includes an 11V voltage signal and a -15V voltage signal.

[0044] For example, the manual button light M may be a red light, and the automatic button light A may be a green light.

[0045] In at least one embodiment of the present application, reference Figure 5The operation button module 112 further includes an anti-accidental touch partition plate P, which is used to isolate two adjacent buttons Q. The surface of the anti-accidental touch partition plate P is higher than the button surface. In this way, by adding the anti-accidental touch partition plate P, the operation button module 112 adopts an anti-accidental touch function partition design, so that when the operator presses any button, the finger is located on the side of the anti-accidental touch partition plate P, which can prevent two adjacent buttons from being pressed at the same time, reduce human errors, and improve reliability.

[0046] In at least one embodiment of the present application, reference Figure 3 The data processing system 22 also includes a setting value storage module connected to the microprocessor 221. The setting value storage module is used to receive and store the final value obtained by the microprocessor 221 by accumulating and calculating the current local setting value. In this way, by adding the setting value storage module connected to the microprocessor 221, the digital graphic display handheld operator can automatically read the final value stored in the setting value storage module after power failure and power on again, so as to restore the local setting value before power failure.

[0047] In at least one embodiment of the present application, reference Figure 3 The data acquisition system 21 includes a digital input (Digital Input, DI) channel module, an analog input (Analog Input, AI) channel module and an analog output (Analog Output, AO) channel module. The digital input module is used to collect digital input signals transmitted by the distributed control system 100. The analog input channel module is used to collect analog input signals transmitted by the distributed control system 100. The analog output channel module is used to transmit analog output signals to the distributed control system 100. In this way, the digital graphic display handheld operator can be better used in conjunction with the DCS system.

[0048] For example, refer to Figure 4 , analog input signals include but are not limited to measurement indication a, remote setting indication b and output indication c. Analog output signals include but are not limited to local setting indication d. Digital input signals include but are not limited to signals of alarm indicator lights. Measurement indication a is used to indicate the current measurement value. Remote setting indication b is used to indicate the current remote setting value. Output indication c is used to indicate the current manual output value. Local setting indication d is used to indicate the current local setting value. Alarm indicator lights are used to indicate fault conditions. Auxiliary lights O can also be set on both sides of output indication c, for example, auxiliary lights O can be yellow.

[0049] The analog output signal may also include a remote / local status indicator e and a remote / local status switch f (simplified as R / L). The remote / local status indicator e is used to indicate whether the current remote or local setting is the setting output of the digital graphic display hand operator. The remote / local status switch f is used to select the remote or local setting as the setting output of the digital graphic display hand operator by pressing a button.

[0050] The analog output signal may also include a manual / automatic state indication g, a feedback indication h, etc. The manual / automatic state indication g is used to indicate the manual / automatic operation state. The feedback indication h is used to indicate the local set value or the remote set value.

[0051] It should be noted that the signal of the alarm indicator light is the switch digital input signal of the DCS system.

[0052] In at least one embodiment of the present application, the digital input signal, analog input signal, and analog output signal transmitted by the data acquisition system 21 are subjected to overvoltage protection and isolation processing. In this way, the signal transmitted by the data acquisition system 21 is stable and has strong anti-interference ability, thereby improving the reliability of the digital graphic display hand operator.

[0053] In at least one embodiment of the present application, reference Figure 1 The electrical connection between the control unit 2 and the display unit 1 is a 32-bit European socket serial port connection N. In this way, the various data processed by the control unit 2 can be better transmitted to the display unit 1 for display, and the display unit 1 can be replaced online without affecting the control function of the control unit 2, thereby improving the maintainability of the digital graphic display hand operator.

[0054] Specifically, the electrical connection between the data processing system 22 in the control unit 2 and the display unit 1 is a 32-bit European socket serial port connection N. Various data processed by the data processing system 22 in the control unit 2 are transmitted to the display unit 1 for display, which does not affect the control function of the data processing system 22.

[0055] It should be noted that the combination of the various technical features in the embodiments of the present application is not limited to the combination described in the embodiments of the present application or the combination described in the specific embodiments, and all technical features described in the present application can be freely combined or combined in any way unless there is a contradiction between them.
