[0034] 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.

[0035] At least one embodiment of the present application provides a pointer display hand operator, which is a display device for a process operator of a regulating loop. Figures 1 to 3 The pointer display operator includes a display module 1 and an operation module 2 connected below the display module 1. The display module 1 includes a measurement pointer 1-1 and a remote given pointer 1-2, both of which use digital control long pointer technology. The measurement pointer 1-1 is used to indicate a measurement value according to a measurement signal received from the outside on the display module 1. The remote given pointer 1-2 is used to indicate a remote given value according to a remote given signal received from the outside on the display module 1.

[0036] In some embodiments, both the measuring pointer 1-1 and the remote given pointer 1-2 can be selected from precise micro digital control pointer meters. For example, the measuring pointer 1-1 can be set to red, and the remote given pointer 1-2 can be set to white background with black lines.

[0037] It should be noted that this digitally controlled long pointer technology is different from the existing dynamic mechanical pointer technology. It can adjust the step angle and operating angular velocity of the output shaft as needed, has a fast response speed, no over-adjustment, and higher display accuracy. At the same time, high-grade ferromagnetic materials and special plastics are selected in the design to eliminate the interference of the magnetic field on the display, taking into account safety performance such as fire prevention, thus ensuring the long-term operating life and performance of the digitally controlled pointer meter.

[0038] For example, the remote setting pointer 1-2 can display the remote setting value according to the received external DC 0-10V remote given signal. The measurement pointer 1-1 can indicate the measurement value according to the received external DC 0-10V measurement signal.

[0039] According to the technical solution provided by the embodiment of the present application, by setting the display module 1 to include a measuring pointer 1-1 and a remote given pointer 1-2, the measuring pointer 1-1 is used to indicate the measured value, and the remote given pointer 1-2 is used to indicate the remote given value. Since both the measuring pointer 1-1 and the remote given pointer 1-2 adopt the digital control long pointer technology, the digital signal can be directly and accurately converted into an analog display output, thereby effectively improving the display accuracy and eliminating the interference of the magnetic field on reality. In addition, since both the measuring pointer 1-1 and the remote given pointer 1-2 adopt the digital control long pointer technology, when the digital control pointer meter is working, the external DC input signal is generated through the data acquisition and processing circuit to generate a gradient pulse sequence to generate a start signal close to a sine wave, so that the digital control pointer meter works in the micro-step mode, and a micro-step output shaft rotates 1 / 12°. In the micro-step mode, the pointer meter can operate more continuously and smoothly.

[0040] In at least one embodiment of the present application, reference Figure 1 , the pointer display operator also includes a jumper connector 3 and a front frame assembly 4. The jumper connector 3 is used for the electrical connection between the rear of the display module 1 and the rear of the operating module 2. The front frame assembly 4 is used for the structural connection between the front of the display module 1 and the front of the operating module 2. In this way, the display module 1 and the operating module 2 can be installed as an integral component. A modular design is adopted. The display module 1 and the operating module 2 can be used independently or in combination. For example, the display module 1 can be used in conjunction with the operating module 2 or used alone for signal indication. The operating module 2 can be equipped with different functional models such as single speed output or dual speed output. Display modules 1 of different functional models can be used in combination with the operating module 2, thereby enriching the process system control configuration scheme.

[0041] After careful study, it was found that the tail of the 30-core electrical pin crown spring pin 1-4 inside the display module of the prior art hand operator is welded to the wire, and the pin is connected to the pin holder 1-3 by the barb structure on the pin, and is plugged with the external 30-core cable plug. This connection method between the pin and the pin holder 1-3 is not reliable enough. After multiple plugging and unplugging, the pin will be retracted into the pin holder 1-3, causing the hand operator to malfunction. In response to this technical problem, the embodiment of the present application has developed a fixed 30-core connector.

[0042] In at least one embodiment of the present application, a 20-pin socket is provided at the rear of the display module 1, and a 30-pin socket is provided at the rear of the operating module 2. The rear of the display module 1 and the rear of the operating module 2 are electrically connected to the 20-pin socket on the display module 1 and the 30-pin socket on the operating module 2 by a standard jumper assembly jumper connector 3. In this way, the electrical connection between the rear of the display module 1 and the rear of the operating module 2 is achieved by using a fixed 30-pin connector including a 20-pin socket and a 30-pin socket, and the connection reliability is improved compared to the existing handheld operator.

[0043] In at least one embodiment of the present application, reference Figures 4 to 6 The display module 1 is provided with a pin holder 1-3, a crown spring pin 1-4, a pin circuit board 1-5 and a fixing screw 1-6. The crown spring pin 1-4 is welded to the pin circuit board 1-5 with the wires laid, and connected to the pin holder 1-3 by the fixing screw 1-6. The crown spring pin 1-4 and the pin circuit board 1-5, and the pin circuit board 1-5 and the pin holder 1-3 are rigidly connected. In this way, the problem that the pin may be retracted into the holder is solved, and the reliability of the hand operator cable connection is improved.

[0044] After careful study, it is also found that when the operator manually adjusts the loop, there is a need to adjust the output value slowly and finely in normal situations, and there is also a need to adjust the output value quickly in emergency situations. In response to the operator's demand for two adjustment speeds, the embodiment of the present application further develops a mechanical shift mechanism, so that the output value has a two-speed selection function, which can take into account both control accuracy and adjustment speed, and effectively improve control accuracy and speed, as shown in the following embodiments.

[0045] In at least one embodiment of the present application, reference Figures 7 to 9 The operation module 2 is provided with a manual lever 2-1, a limit pin 2-2, a reset spring 2-3, a manual transfer link 2-4, an operator control panel 2-5, a contact spring 2-6 and a manual setting dial 2-7. A manual setting dial 2-7 is provided on the shaft of the manual transfer link 2-4, which rotates in conjunction with the manual transfer link 2-4. A contact spring 2-6 is provided in the manual setting dial 2-7. The contact spring 2-6 is elastically pressed against the contact surface of the pad on the operator control panel 2-5, and is embedded in the reset spring 2-3 of the manual transfer link 2-4. The manual lever 2-1 rotates in conjunction with the manual transfer link 2-4, and a limit pin 2-2 is provided at the front of the operation module 2.

[0046] Specifically, the manual operating lever 2-1 is turned to drive the manual transfer connecting rod 2-4 to rotate and the manual setting dial 2-7 to rotate in conjunction. The contact spring 2-6 in the manual setting dial 2-7 is an active contact, and the welding pad on the operator control panel 2-5 is a fixed contact. The contact spring 2-6 can be rotated to close with the fixed contacts of different gears, thereby connecting the corresponding circuit and completing the control action; the manual operating lever 2-1 is the default gear when it is in the center position. It is moved horizontally to the left / right to the first locking pin position of the limit pin 2-2 for a slow gear reduction / increase. It is biased upward and exceeds the limit pin 2-2 for a fast gear reduction / increase. After exceeding the limit pin 2-2, it is pressed down to the locking position, which can be limited to remain in this gear. In the maintained state, pressing the manual operating lever 2-1 can be reset to the default gear by the reset spring 2-3.

[0047] It should be noted that the reset spring 2-3 embedded in the manual transfer link 2-4 can realize the self-reset function by elastically pressing the contact spring 2-6 and the pad contact surface on the operator control panel 2-5. The manual lever 2-1 is used to adjust the output of the adjustment unit in the manual state and provide a contact closure. The manual setting dial 2-7 is used to adjust the local setting value. When the manual setting dial 2-7 is turned upward, the local setting value is increased, and when it is turned downward, the local setting value is reduced. After the local setting value is set by the manual setting dial 2-7, it can be transmitted to the local setting pointer 1-11 for display with an adjustable DC 0~10V local setting signal.

[0048] In view of the application mode of the hand operator on the control panel, a rotating panel fixing structure is developed to facilitate the disassembly and assembly of the hand operator on the panel 5 of the panel, as shown in the following embodiments.

[0049] In at least one embodiment of the present application, reference Figures 10 to 13 , a display module cam clamp 1-7 is provided at the upper end of the rear of the display module 1, and an operation module cam clamp 2-8 is provided at the lower end of the rear of the operation module 2. The display module cam clamp 1-7 and the operation module cam clamp 2-8 both have an extended state and a retracted state. When the display module cam clamp 1-7 and the operation module cam clamp 2-8 are both in the retracted state, the pointer display hand operator is put into the hole of the disk table panel 5 until the front of the pointer display hand operator is limited to clamp the outer surface of the disk table panel 5, and then the display module cam clamp 1-7 and the operation module cam clamp 2-8 are both set to the extended state to clamp the inner surface of the disk table panel 5.

[0050] For example, the first cam screw is rotated to the left and right respectively to rotate the first cam to drive the display module cam clamp 1-7 to retract the outer edge of the pointer display hand operator. The second cam screw is rotated to the left and right respectively to rotate the second cam to drive the operation module cam clamp 2-8 to retract the outer edge of the pointer display hand operator. After the display module cam clamp 1-7 and the operation module cam clamp 2-8 have fully retracted the outer edge of the pointer display hand operator, the pointer display hand operator is placed into the hole of the disk table panel 5 until the front of the pointer display hand operator is limited and clamped on the outer surface of the disk table panel 5, the first cam screw is rotated in the opposite direction to extend the display module cam clamp 1-7 to the outer edge of the pointer display hand operator, and the second cam screw is rotated in the opposite direction to extend the operation module cam clamp 2-8 to the outer edge of the pointer display hand operator, and the first cam screw and the second cam screw are rotated to move the display module cam clamp 1-7 and the operation module cam clamp 2-8 toward the inner surface of the disk table panel 5 until the inner surface of the disk table panel 5 is clamped, thereby achieving the effect of clamping the disk table panel 5.

[0051] It should be noted that the rotating panel fixing structure at least includes a display module cam clamp 1-7 and an operation module cam clamp 2-8.

[0052] In at least one embodiment of the present application, reference Fig.14 and Fig.15 , the front of the display module 1 is also provided with a measurement setting scale 1-8, a remote / local status switch 1-9, a light emitting diode 1-10 and a local setting pointer 1-11. The measurement setting scale 1-8 is located in the middle area of ​​the front of the display module 1, the light emitting diode 1-10 is located on the central axis of the measurement setting scale 1-8, and the measurement pointer 1-1, the remote given pointer 1-2 and the remote / local status switch 1-9 are located on the same side of the measurement setting scale 1-8. The local setting pointer 1-11 is located on the other side of the measurement setting scale 1-8. The remote / local status switch 1-9 is used to indicate the remote setting or the local setting as the setting value of the adjustment unit.

[0053] In at least one embodiment of the present application, reference Fig.14 and Fig.15 , the front of the operation module 2 is also provided with an output meter 2-9, an automatic button 2-10, an automatic indicator light 2-11, a manual button 2-12, a manual indicator light 2-13 and an auxiliary light 2-14. The automatic button 2-10 and the manual button 2-12 are located in the same row below the output meter 2-9. The automatic indicator light 2-11, the manual indicator light 2-13 and the auxiliary light 2-14 are all located in the same row below the automatic button 2-10 and the manual button 2-12. The output meter 2-9 is used to indicate the output on a 0-100% scale. The automatic button 2-10 is used to select the automatic mode of the adjustment unit. The automatic indicator light 2-11 is used to light up when the automatic mode is selected. The manual button 2-12 is used to select the manual mode of the adjustment unit. The manual indicator light 2-13 is used to light up when the manual mode is selected. The auxiliary light 2-14 is used to indicate other states.

[0054] It should be noted that the measurement setting scale 1-8 can be set according to user specifications. For example, the measurement setting scale 1-8 can be divided on an 80 mm vertical scale. The automatic indicator light 2-11 can be green, the manual indicator light 2-13 can be red, and the auxiliary light 2-14 can be yellow. The auxiliary light 2-14 can be a power indicator light for monitoring the power supply of the pointer display handheld operator. The output table 2-9 can indicate the output according to the received external DC 0~10 V output signal.
