The memory 102 stores a computer program, and when the computer program is executed by the processor 101, the electronic device 100 can perform the corresponding steps in the following pressure transmitter calibration method.

[0038] In this embodiment, the processor 101 may be an integrated circuit chip having signal processing capabilities. The processor 101 may be a general-purpose processor. For example, the processor 101 may be a central processing unit (CPU), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, and may implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of the present application.

[0040] In this embodiment, the electronic device 100 may be a personal computer, a laptop computer, etc. It is used to obtain the connection state of the pressure transmitter body, and then when receiving the first instruction, the connection state is set to the first target state representing that the pressure transmitter body is connected to the standard pressure source through the electric three-way valve, and finally based on the first target state, the pressure transmitter body is calibrated through the standard pressure source. In this way, the surface disassembly calibration of the pressure transmitter is achieved.

[0041] An embodiment of the present application also provides a pressure transmitter calibration device, including the above-mentioned electronic device 100, a pressure transmitter body, a calibration pressure source and an electric three-way valve.

[0042] It can be understood that the pressure transmitter calibration device in this embodiment is used to calibrate the pressure transmitter on the production line. Therefore, the electric three-way valve is respectively connected to the production line, the calibration pressure source and the pressure transmitter body. By controlling the valve of the electric three-way valve, the pressure transmitter body is selected to be connected to the production line or the calibration pressure source.

[0043] In this embodiment, when the calibration pressure source is used to calibrate the pressure transmitter body, a fixed value of pressure is applied to the pressure transmitter body, and the application method can be achieved through a medium such as fluid or gas.

[0044] Please refer to Figure 2 The present application also provides a pressure transmitter calibration method, which can be applied to the above electronic device 100, and each step in the method is executed or implemented by the electronic device 100. The pressure transmitter calibration method can include the following steps:

[0045] Step 210, obtaining the connection state of the pressure transmitter body, wherein the connection state indicates the connection state of the pressure transmitter body with the production line or the standard pressure source through the electric three-way valve;

[0046] Step 220, when receiving a first instruction representing switching the connection state, setting the connection state to a first target state, wherein the first target state represents that the pressure transmitter body is connected to the standard pressure source through the electric three-way valve;

[0047] Step 230: Based on the first target state, calibrate the pressure transmitter body through the standard pressure source.

[0048] In the above implementation, the connection state of the pressure transmitter body is first obtained, and then when the first instruction is received, the connection state is set to the first target state indicating that the pressure transmitter body is connected to the standard pressure source through the electric three-way valve, and finally based on the first target state, the pressure transmitter body is calibrated through the standard pressure source. In this way, the electric three-way valve is used to achieve flexible connection between the pressure transmitter and the production line and the calibration pressure source, which facilitates the pressure transmitter to avoid disassembly during calibration and does not affect the operation of the production line, thereby improving the problems of low efficiency and high production line shutdown costs in the traditional pressure transmitter calibration method.

[0049] The following will describe in detail the various steps of the pressure transmitter calibration method, as follows:

[0050] In step 210, the connectivity status of the pressure transmitter body can be obtained by monitoring the opening and closing of the electric three-way valve. For example, when the valve between the pressure transmitter and the calibration pressure source is opened, the connectivity status of the pressure transmitter body can be a first target state indicating that the pressure transmitter body is connected to the calibration pressure source. When the valve between the pressure transmitter and the production line is opened, the connectivity status of the pressure transmitter body can be a second target state indicating that the pressure transmitter body is connected to the production line.

[0051] In this embodiment, the connection state of the pressure transmitter body can be acquired by monitoring the opening and closing state of the electric three-way valve and uploading it to the processor 101 of the electronic device 100 in real time for subsequent processing, or it can be stored in the memory 102 of the electronic device 100 after monitoring the opening and closing state of the electric three-way valve, and then called based on the subsequent operation instructions initiated by the user. The method for acquiring the connection state is not specifically limited here.

[0052] In step 220, the first instruction may be that when the user needs to inspect or calibrate the pressure transmitter body, the user closes the valve of the electric three-way valve between the pressure transmitter body and the production line to facilitate the disassembly of the pressure transmitter body or opens the valve between the pressure transmitter body and the calibration pressure source for calibration operations; or, the first instruction may also be a script pre-defined by the user and stored in the electronic device 100, which sends the first instruction to the electric three-way valve at a user-defined frequency (for example, 1 time / hour, 1 time / 3 hours, 1 time / day, etc.) to control the opening and closing of the electric three-way valve.

[0053] In step 230, the electric three-way valve is adjusted to a first target state through a first instruction, that is, the pressure transmitter body is connected to the calibration pressure source to perform a pressure transmitter calibration operation.

[0054] In this embodiment, based on the first target state, calibrating the pressure transmitter body by using the standard pressure source may include:

[0055] Applying zero pressure to the pressure transmitter body through the standard pressure source, and performing zero point calibration on the pressure transmitter body until the pressure output detected by the pressure transmitter body is zero;

[0056] A preset pressure is applied to the pressure transmitter body through the standard pressure source, and a range calibration is performed on the pressure transmitter body until the pressure output detected by the pressure transmitter body is the same as the preset pressure.

[0057] In this embodiment, applying a preset pressure to the pressure transmitter body through the standard pressure source, and performing a range calibration on the pressure transmitter body until the pressure output detected by the pressure transmitter body is the same as the preset pressure, may include:

[0058] Obtaining loss parameters when the standard pressure source pressurizes the pressure transmitter body, the loss parameters including pipeline material damping coefficient, pipeline length, pipeline inner diameter, medium density, medium flow rate, and pipeline characteristic damping coefficient;

[0059] Determining the pressure loss when the standard pressure source applies pressure to the pressure transmitter body according to the loss parameter;

[0060] Obtaining the pressure output detected by the pressure transmitter body;

[0061] Determining an error between the pressure output and an actual pressure magnitude according to the pressure output and the pressure loss;

[0062] According to the error, the range of the pressure transmitter body is calibrated until the pressure output is the same as the preset pressure.

[0063] It is understandable that in actual applications, although the pressure output by the standard pressure source is of standard size when it is output, when the medium used to generate pressure flows between the standard pressure source and the pressure transmitter body, pressure loss is inevitable due to factors such as pipeline length, material, and shape. Therefore, when calculating the error between the pressure output detected by the pressure transmitter body and the actual pressure size, it is also necessary to compensate for the loss caused by the transmission of the medium in the pipeline.

[0064] Specifically, the error between the pressure output and the actual pressure = the preset pressure output by the standard pressure source - (pressure output + pressure loss). The calculation formula for pressure loss is as follows:

[0065]

[0066]

[0067]

[0068] In the formula, Indicates the resistance loss caused by the pipe material to the medium. It indicates the resistance loss caused to the medium by pipeline characteristics (such as elbow shape, number of elbows, etc.). represents the material damping coefficient of the pipe, Indicates the length of the pipeline, Indicates the inner diameter of the pipe. represents the density of the medium, Indicates the medium flow rate, Represents the characteristic damping coefficient of the pipe.

[0069] It is understandable that in practical applications, the detection data of the equipment should have a certain margin of error, that is, the end condition of zero-point calibration can be not only that the pressure output detected by the pressure transmitter body is zero, but also that the value of the pressure output is within the value range preset by the user, that is, the zero-point calibration is considered valid. The same is true for range calibration.

[0070] In this embodiment, zero point calibration and span calibration are conventional technical means in the technical field of pressure transmitter calibration, which will not be described in detail here.

[0071] As an optional implementation, the method may further include:

[0072] After the pressure transmitter body is calibrated, upon receiving a second instruction indicating switching of the connection state, the connection state is set to a second target state, wherein the second target state indicates that the pressure transmitter body is connected to the production line through the electric three-way valve.

[0073] It is understandable that after completing the calibration of the pressure transmitter body, in order for the pressure transmitter to re-enter the tobacco production line operation more smoothly, the user can initiate a second instruction through the above-mentioned electronic device 100 immediately after completing the calibration, or through a pre-edited script, send a second instruction to the pressure transmitter body immediately after the calibration is completed, and forward the second instruction to the electric three-way valve through the pressure transmitter body, thereby setting the valve of the electric three-way valve to the second target state, that is, the pressure transmitter body is connected to the production line through the electric three-way valve, so that the pressure transmitter can quickly enter the pressure monitoring operation of the production line.

[0074] Alternatively, in order to prevent the user from forgetting to return the pressure transmitter to the production line after calibration, or an error in pre-editing resulting in the pressure transmitter body failing to connect with the production line after calibration, if the second instruction is not received after a first preset time after the pressure transmitter body is calibrated, the connection state may be set to the second target state after a second preset time delay.

[0075] It is understandable that by delaying the second preset time and then controlling the electric three-way valve to change the connection state, a certain fault tolerance space can be reserved for the pressure transmitter to enter the production line monitoring operation to prevent the pressure transmitter from being put into production operation without being effectively calibrated.

[0076] As an optional embodiment, the method may also include: if the first instruction or the second instruction is not received within a third preset time period before the current moment, and the pressure transmitter body is in a startup state, then the connection state is a second target state characterizing that the pressure transmitter body is connected to the production line through the electric three-way valve.

[0077] In this embodiment, in order to prevent the electric three-way valve from changing its connection state after a long period of time without user operation, the pressure transmitter body may always be in an unoperated state (i.e., connected to the calibration pressure source but not calibrated), thereby affecting the regular operation of the production line and causing production accidents. In this embodiment, if the first instruction or the second instruction is not received within the third preset time (flexibly set by the user, such as 20 minutes, half an hour, 1 hour, 3 hours, etc.) before the current moment, and the pressure transmitter body is always in the startup state, the connection state is switched to the second target state, that is, the pressure transmitter body is put into production line operation to avoid the pressure transmitter body being shelved for a long time.

[0078] As an optional implementation, the method may further include:

[0079] When the pressure transmitter body is in an abnormal working state, the connection state is set to a second target state indicating that the pressure transmitter body is connected to the production line through the electric three-way valve;

[0080] Furthermore, when the pressure transmitter body is in an abnormal working state, a prompt message indicating that the pressure transmitter body is abnormal is issued.

[0081] In this embodiment, the working state of the pressure transmitter body can be monitored in real time. When it is detected that the pressure transmitter body is in an abnormal working state (for example, the working voltage is unstable, the output pressure value is obviously inconsistent with the actual situation, etc.), the electric three-way valve is set to the second target state, that is, the connection between the pressure transmitter body and the production line is cut off, so that the pressure transmitter body can be disassembled, repaired or calibrated. In addition, in order to prompt the user to perform immediate maintenance when a problem occurs with the pressure transmitter, when the pressure transmitter body is in an abnormal working state, a prompt message indicating that the pressure transmitter body is abnormal is issued (for example, a warning is issued by a buzzer integrated in the pressure transmitter body, a pop-up prompt is issued by the electronic device 100, etc.).

[0082] Understandably, Figure 1 The structure of the electronic device 100 shown in FIG. 1 is only a schematic diagram of a structure. The electronic device 100 may also include Figure 1 More components are shown. Figure 1 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

The computer-readable storage medium stores a computer program, and when the computer program is run on a computer, the computer executes the pressure transmitter calibration method described in the above embodiment.

[0085] The embodiment of the present application further provides a computer program product, including a computer program. When the computer program is executed by the processor 101101, the pressure transmitter calibration method described in the above embodiment can be implemented.

Based on such an understanding, the technical solution of the present application can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a USB flash drive, a mobile hard disk, etc.), including a number of instructions for enabling a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each implementation scenario of the present application.

[0087] In summary, the embodiments of the present application provide a pressure transmitter calibration method, device, electronic device and program product. In this technical solution, the connectivity state of the pressure transmitter body is first acquired, and then, in response to a first instruction, the connectivity state is set to a first target state that represents that the pressure transmitter body is connected to a standard pressure source through an electric three-way valve, and finally, based on the first target state, the pressure transmitter body is calibrated through the standard pressure source. In this way, the pressure transmitter is flexibly connected to the production line and the calibration pressure source through the electric three-way valve, which facilitates the pressure transmitter to avoid disassembly during calibration and does not affect the operation of the production line, thereby improving the problems of low efficiency and high production line shutdown costs in traditional pressure transmitter calibration methods.
