[0035] In order to make the objectives, technical solutions and advantages of this application more clear, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0036] In one embodiment, this application provides a pressure measurement device calibration device, as Figure 1 shown, which includes a data acquisition module 100, a data transmission module 200, a data storage module 300, and a server module 400. Among them, the data transmission module 200 is respectively connected to the data acquisition module 100 and the data storage module 300, and the data storage module 300 is also connected to the server module 400.

[0037] The data acquisition module 100 is used to collect the output signal of the pressure measurement device when the system pressure reaches a preset value, and generate calibration data according to the output signal. The pressure measurement device includes a pressure transmitter, a pressure switch, etc. The output signal of the pressure measurement device can be an electrical signal or a switching quantity signal. The switching quantity signal can actually also be represented by an electrical signal. The preset value can be set before the initialization of the pressure measurement device calibration device, and the specific value of the preset value can be reasonably set according to the verification requirements. The calibration data includes a preset value, an output signal, a standard signal, and a basic error. The standard signal is associated with the preset value. The standard signal refers to the electrical signal output by a standard pressure measurement device when the system pressure reaches the preset value. The standard pressure measurement device refers to a pressure measurement device that operates normally and has no faults. During the actual calibration process, the preset value and the corresponding standard signal can be sent or stored in the data acquisition module 100 in advance for the data acquisition module 100 to directly call, or another high-precision pressure measurement device can be set to measure the system pressure at the same time, and the output signal of this high-precision pressure measurement device is used as the standard signal. The basic error is the difference between the output signal and the standard signal.

[0038] The data transmission module 200 is used to receive and transmit the calibration data. The data transmission module 200 can be a field maintenance terminal, for example, it can be an industrial tablet. The data transmission module 200 communicates wirelessly with the data acquisition module 100. For example, it can communicate through a LoRa terminal, 5G, 4G, Bluetooth, Zigbee, eMTC, NB-IoT, WiFi, etc. The data transmission module 200 can act as a router to transmit the calibration data from the data acquisition module 100 to the data storage module 300 for storage.

[0039] The data storage module 300 is used to store the received verification data. The data storage module 300 can use a relational database to store the verification data. Exemplarily, relational tables such as a pressure device ledger, verification records, and calculation results can be established based on the verification data to facilitate rapid storage and retrieval.

[0040] The server module 400 is used to call the verification data from the data storage module 300 and perform verification processing on the verification data to determine the verification result. The server module 400 can calculate the verification data to obtain the verification result.

[0041] In the embodiment of the present application, the pressure measurement device verification device includes a data acquisition module 100, a data transmission module 200, a data storage module 300, and a server module 400. Among them, the data acquisition module 100 is used to collect the output signal of the pressure measurement device when the system pressure reaches a preset value, and generate verification data according to the output signal. The data transmission module 200 is used to receive and transmit the verification data. The data storage module 300 is used to store the received verification data. The server module 400 is used to call the verification data from the data storage module 300 and perform verification processing on the verification data to determine the verification result. It can be understood that by automatically collecting the output signal of the pressure measurement device through the data acquisition module 100 and generating verification data, receiving the verification data through the data transmission module 200, and transmitting the verification data to the data storage module 300 for storage, the manual operation nodes are eliminated, and the operation errors and data deviations that may be caused by manual intervention are avoided. In addition, the verification data is stored by the data storage module 300. Since the data storage module 300 has a large storage capacity, a large amount of verification data can be stored, which is convenient for subsequent tracing of historical data. The server module 400 determines the verification result according to the verification data, and the data can be uniformly exported for convenient data management.

[0042] In one embodiment, as Figure 2 shown, the data acquisition module 100 includes a pressure calibrator 110, a data collector 120, and a communication unit 130. The pressure calibrator 110 is respectively connected to the pressure measurement device and the data collector 120, and the communication unit 130 is respectively connected to the data collector 120 and the data transmission module 200.

[0043] The pressure calibrator 110 is used to collect the output signal of the pressure measurement device when the system pressure reaches a preset value, and generate verification data according to the output signal. Further, the pressure calibrator 110 is also used to collect the output signal of the pressure measurement device when the system pressure reaches a preset value, and determine the basic error according to the output signal and the standard signal.

[0044] The data collector 120 is used to collect verification data. Exemplarily, the data collector 120 can be connected to the pressure calibrator 110 through the RS23 interface to collect the verification data of the pressure calibrator 110.

[0045] The communication unit 130 is used to transmit the verification data to the data transmission module 200. Exemplarily, the communication unit 130 can be at least one of a LoRa terminal, a 5G private network, a 4G private network, a Bluetooth unit, a Zigbee unit, an eMTC unit, an NB-IoT unit, a WiFi unit, etc.

[0046] In one embodiment, the number of preset values can be multiple, and the pressure calibrator 110 is also used to control the system pressure to increase or decrease according to the multiple preset values. Exemplarily, the preset values can be 0%, 25%, 50%, 75% and 100% of the range of the pressure measuring device respectively. During the upstroke verification process, the pressure calibrator 110 can control the system pressure to increase; during the downstroke verification process, the pressure calibrator 110 can control the system pressure to decrease.

[0047] In one embodiment, the server module 400 is also used to determine the basic error and the hysteresis error according to the verification data, and determine the verification result according to the basic error and the hysteresis error. The basic error includes the upstroke basic error and the downstroke basic error. The hysteresis error is the difference between the downstroke basic error and the upstroke basic error corresponding to the same preset value. The verification result includes verification qualified and verification unqualified. The server module 400 can determine that the verification is unqualified when the hysteresis error and the basic error exceed the corresponding preset range, and determine that the verification is qualified when both the hysteresis error and the basic error are within the corresponding preset range.

[0048] The server module 400 is also used to generate a verification report when the verification result is verification qualified, and generate a verification report and re-perform the verification when the verification result is verification unqualified.

[0049] In this embodiment, the server module 400 can determine the basic error and the hysteresis error according to the verification data, and determine the verification result according to the basic error and the hysteresis error. Further, when the verification result is verification qualified, a verification report is generated, and when the verification result is verification unqualified, a verification report is generated and the verification is re-performed, realizing the automatic calculation of the verification result and the automatic generation of the verification report.

[0050] In one embodiment, the server module 400 is further configured to perform data parsing processing, data cleaning processing, and data conversion processing on the verification data. The data parsing processing is to format the verification data. Since the verification data stored in the data storage module 300 may come from different data acquisition modules 100, it is necessary to convert the verification data from different sources and in different formats into a unified format for convenient data management. The data cleaning processing refers to identifying and processing missing data, removing duplicate data, correcting incorrect data, and standardizing the data range. The data conversion processing is to perform normalization processing on the data, usually scaling the data to a specific range, such as between 0 and 1 or between -1 and 1, for convenient data analysis.

[0051] In one embodiment, the pressure measurement device calibration apparatus further includes a service operation module. The service operation module is connected to the server module 400 and is configured to provide a visual operation interface and export a calibration report in response to a touch operation on the visual operation interface. After generating the calibration report, the server module 400 can store the calibration report in the data storage module 300, and the service operation module can export the calibration report from the data storage module 300 in response to a touch operation on the visual operation interface.

[0052] In addition, the service operation module can also obtain parameter information such as preset values through the touch operation of the user on the visual operation interface, and send the parameter information to the server module 400, which is then sent to the corresponding data acquisition module 100 through the data transmission module 200.

[0053] In one embodiment, the server module 400 and the service operation module can be integrated in the same computer device. The computer device can be a terminal, and its internal structure diagram can be as Figure 3As shown in the figure. The computer device includes a processor, a memory, an input / output interface, a communication interface, a display unit, and an input device. Among them, the processor, the memory, and the input / output interface are connected through a system bus, and the communication interface, the display unit, and the input device are connected to the system bus through the input / output interface. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The input / output interface of the computer device is used to exchange information between the processor and external devices. The communication interface of the computer device is used to communicate with external terminals in a wired or wireless manner. The wireless manner can be achieved through WIFI, a mobile cellular network, near field communication (NFC), or other technologies. When the computer program is executed by the processor, it can start the calibration process of the pressure measurement device. The display unit of the computer device is used to form a visually visible picture, which can be a display screen, a projection device, or a virtual reality imaging device. The display screen can be a liquid crystal display screen or an electronic ink display screen. The input device of the computer device can be a touch layer covering the display screen, or a button, a trackball, or a touchpad provided on the housing of the computer device, or an external keyboard, touchpad, or mouse, etc.

[0054] In one embodiment, the data storage module 300 includes a structured storage unit and an unstructured storage unit. Among them, the structured storage unit can be used to store data such as calibration data, pressure device ledger, calibration records, and calculation results, and the unstructured storage unit can be used to store unstructured data, such as image, video, audio, text, etc.

[0055] Those skilled in the art can understand that Figure 3 the structure shown in the figure is only a block diagram of some structures related to the solution of the present application, and does not constitute a limitation on the computer device to which the solution of the present application is applied. The specific computer device may include more or fewer components than those shown in the figure, or combine some components, or have different component arrangements.

[0056] It should be understood that each module in the above pressure measurement device calibration device can be implemented in whole or in part through software, hardware, and their combination. The above modules can be embedded in the processor of the computer device in hardware form or independent of it, or stored in the memory of the computer device in software form, so that the processor can call and execute the operations corresponding to the above modules.

[0057] In one embodiment, as Figure 4As shown in the figure, the present application also provides a method for calibrating a pressure measurement device, which can be applied to the pressure measurement device calibration device provided in any of the above embodiments. The pressure measurement device calibration method includes steps S100-S300.

[0058] S100, when the system pressure reaches a preset value, use the data acquisition module to collect the output signal of the pressure measurement device, and generate calibration data according to the output signal.

[0059] S200, transmit and store the calibration data to the data storage module.

[0060] S300, call the calibration data from the data storage module, and perform calibration processing on the calibration data to determine the calibration result.

[0061] Among them, before step S100, it is necessary to initialize the pressure measurement device calibration device first, complete self-check and configuration of calibration parameters. The configuration of calibration parameters includes setting a preset value and setting a preset range corresponding to the basic error and the return error, etc.

[0062] Step S300 includes determining the basic error and the return error according to the calibration data, and determining the calibration result according to the basic error and the return error. When the calibration result is qualified, generate a calibration report, and when the calibration result is unqualified, generate a calibration report and perform calibration again.

[0063] In this embodiment, when the system pressure reaches the preset value, the data acquisition module is used to collect the output signal of the pressure measurement device, and calibration data is generated according to the output signal. The calibration data is transmitted and stored in the data storage module. The calibration data is called from the data storage module, and calibration processing is performed on the calibration data to determine the calibration result, realizing automatic calibration of the pressure measurement device, eliminating manual operation nodes, and avoiding operation errors and data deviations that may be caused by manual intervention. Moreover, by transmitting and storing the calibration data to the data storage module, since the data storage module has a large storage capacity, a large amount of calibration data can be stored, which is convenient for subsequent traceability of historical data.

[0064] In one embodiment, a more specific embodiment is listed to illustrate the calibration process of the pressure measurement device calibration device provided by the present application.

[0065] Such as Figure 5As shown, the pressure measurement device calibration device first completes initialization. In the initialization stage, each module in the pressure measurement device calibration device processes in parallel: the data collector is initialized, the pressure calibrator performs self-check, and the communication unit performs self-check. After that, the calibration parameters are set according to the parameter information obtained by the user's touch operation on the service operation module, including configuring the measurement points (i.e., preset values) of the pressure calibrator and the judgment criteria (i.e., the preset ranges corresponding to the basic error and the hysteresis error) of the server module. The calibration process starts. During the calibration process, each module in the pressure measurement device calibration device still runs in parallel: the pressure calibrator performs the upstroke calibration and the downstroke calibration respectively, the data collector collects the corresponding calibration data, and stores the calibration data in the data storage module through the data transmission module. The server module calls the calibration data in real time from the data storage module, calculates the basic error and the hysteresis error according to the calibration data, and judges whether the calibration result is qualified based on the basic error and the hysteresis error. If the calibration result is qualified, a calibration report is generated. If the calibration result is unqualified, the calibration result is recorded and the calibration process is restarted.

Unless there is a clear indication in this article, the execution of these steps has no strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages. These steps or stages do not necessarily need to be executed at the same time, but can be executed at different times. The execution order of these steps or stages does not necessarily need to be sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.

[0067] Those of ordinary skill in the art can understand that all or part of the processes in the methods of the above embodiments can be completed by instructing relevant hardware through a computer program. The computer program can be stored in a non-volatile computer-readable storage medium. When the computer program is executed, it can include the processes of the embodiments of the above methods.
