[0113] Based on the above main structure, Figure 5 As shown, another specific combination of the verification modules can form a pressure temperature recorder, including a main body, a main body having a main board module 100 fixed therein, a display screen 510 fixedly provided on the front of the main body, the display screen 510 being electrically connected to the main board module 100, a first module configuration position being provided at the first end of the main body, a general electrical measurement board 620 and a temperature measurement board 640 being both configured at the first module configuration position and being respectively adapted and connected to the main board module 100, a second module configuration position being provided at the second end of the main body, the second module configuration position being used to configure a sensor module or a high-voltage measurement module, a main board module being provided with an adapted connector 130 near the second module configuration position, a third module configuration position being provided at the third end of the main body, a signal connector 540 being configured at the third module configuration position and being adapted and connected to the main board module 100, and the signal connector 540 being used to connect signals with an external temperature or pressure detection device;

[0114] Further optimized, the pressure sensor module 520 is configured at the second module configuration position and is adapted to be connected with the mainboard module 100;

[0115] Further optimized, the high-voltage measurement module is configured at the second module configuration position and is adapted and connected to the main board module;

[0116] Further optimized and compatible with the first module configuration, the mainboard module is provided with a plurality of mutually parallel plug-in terminals, and the first electrical measurement board and the second electrical measurement board are respectively plug-connected to the mainboard module;

[0117] It is used to power the internal components of the pressure calibrator. It can be powered by a built-in battery module electrically connected to the main board module, or by setting a power interface to be electrically connected to an external power supply, and the power interface to be electrically connected to the main board module, so as to use an external power supply.

[0118] It can be seen from the above technical solution that the modules arranged in each module configuration position in this specific embodiment are not selected randomly, but the verification modules are selected and combined according to the specific verification object and verification device, so that the verification of the specific detection amount can be finally formed.

[0119] Summarizing the aforementioned various specific verification module combination methods, there is a combination configuration method of a handheld verification device, including:

[0120] Select one or two or more functional circuit boards according to the type of the verification device, at least one functional circuit board can measure the input detection quantity, place the functional circuit board in the first module configuration position, and make the functional circuit board electrically connected to the main board module through the first connecting component;

[0121] Select a sensor module or a high-voltage measurement module according to the type of the calibration device, place the sensor module or the high-voltage measurement module in the second module configuration position, and electrically connect the sensor module or the high-voltage measurement module to the mainboard module through the second connection component;

[0122] A connector module is selected according to the type of the verification device, and the connector module is placed in the second module configuration position, so that the connector module is electrically connected to the mainboard module through the third connection component.

[0123] A feasible specific method for selecting the type of the verification device in the above includes:

[0124] Determine the specific type of calibration device to be formed, such as pressure calibrator, temperature calibrator, process calibrator, pressure temperature recorder, temperature and humidity recorder, etc.;

[0125] Determine the corresponding detection quantity according to the specific type of calibration device. For example, for a pressure calibrator, the corresponding detection quantity is the pressure quantity; the same applies to other types of calibration devices.

[0126] Determine the circuit board or module that can obtain the detection quantity according to the type of detection quantity. For example, for pressure quantity, the electrical measurement board can measure the electrical signal that represents the pressure quantity, so the electrical measurement board is configured in the first module configuration position. The pressure sensor module can directly measure the pressure, so the pressure sensor module is configured in the second module configuration position; the same applies to other types of detection quantities.

[0127] Another feasible specific method of selecting according to the type of the verification device in the above includes:

[0128] Determine the specific type of calibration device to be formed, such as pressure calibrator, temperature calibrator, process calibrator, pressure temperature recorder, temperature and humidity recorder, etc.;

[0129] The required circuit board or module is directly determined according to the type of the verification device. The specific direct determination method can be various methods such as table lookup and experience.

[0130] The mainboard module simultaneously obtains two detection quantities through at least one of the first connection component, the second connection component or the third connection component. The two detection quantities are the same type of detection quantities or related detection quantities, specifically including:

[0131] In one case, the two measured quantities are of the same type and are pressure quantities, temperature quantities, or process electrical signals. Furthermore, one of the two measured quantities is a standard measured quantity and the other is a calibrated measured quantity. From another perspective, the standard measured quantity and the calibrated measured quantity can also be regarded as a form of associated measured quantities because the measurement object is the same pressure.

[0132] In another case, the two detected quantities are of different types and are one of the following combinations: pressure quantity and temperature quantity, or temperature quantity and humidity quantity; or they may be other related detected quantities that influence each other.

[0133] For example, the technical solution of the above specific embodiment may be improved as follows:

[0134] The first module configuration position includes a cavity that can accommodate two or more functional circuit boards. Corresponding to the first module configuration position, a connection component is provided on the mainboard module. The connection component includes two or more connection terminals. The functional circuit board configured in the first module configuration position is adapted to be connected with one of the connection terminals. Further, the connection terminals are plug-in terminals, and the arrangement positions of the plug-in terminals are different and the plug-in directions are the same. The connection positions of the connection terminals are parallel to each other and are located in different planes. Two adjacent connection terminals extend vertically along the mainboard module. One of the connection terminals is coplanar with the mainboard module.

[0135] Furthermore, the functional circuit board is plug-connected with the main board module at the first module configuration position; two or more functional circuit boards are configured at the first module configuration position, and the functional circuit boards are parallel to each other; and there is a functional circuit board coplanar with the main board module.

[0136] For example, the technical solution of the above-mentioned specific embodiment is improved, and the functional circuit board configured in the first module configuration position may include a general electrical measurement board, a temperature measurement board, a measurement output board and an electrical output board:

[0137] General electrical measurement boards can measure one or more electrical signals including voltage, current, frequency, pulse, switch, loop current, and HART based on the actual configured functions;

[0138] Temperature measurement board, a type of electrical measurement board dedicated to temperature measurement. When the measurable object includes a thermal resistor, the temperature measurement board can measure the resistance signal. When the measurable object includes a thermocouple, the temperature measurement board can measure the thermoelectromotive force (voltage) signal.

[0139] The measurement output board can simultaneously support the measurement and generation of one or more electrical signals of voltage, current, resistance, frequency, pulse, switch, loop current, and HART; specifically, the electrical signals measured and generated by the measurement output board are related or of the same type. For example, a measurement output board is dedicated to temperature measurement. When the calibration object includes a thermal resistor, the measurement output board can measure the resistance signal and generate a simulated resistance signal. When the calibration object includes a thermocouple, the measurement output board can measure the thermoelectromotive force signal and generate a simulated thermocouple (electromotive force) signal.

[0140] The electrical output board, based on the actual configured functions, can generate one or more electrical signals of voltage, current, frequency, pulse, switch, loop current, HART according to the instructions;

[0141] Depending on the verification object or verification device, the functional circuit board actually configured in the verification device may be one of the aforementioned types, a combination of two, or a combination of three.

[0142] For example, the technical solution of the above specific embodiment is improved to obtain the detection amount:

[0143] The first module configuration position is configured with an electric measurement board, the main board module is connected to the electric measurement board by signal, the electric measurement board can obtain the detection quantity required for verification, when there are multiple detection quantities required for verification, the electric measurement board can obtain at least one of the detection quantities;

[0144] The configuration of the first module can be combined or replaced with the configuration of the electrical measurement board, the electrical measurement output board is configured, and the main board module is connected to the electrical measurement output signal; the electrical measurement output board can obtain the detection quantity required for verification, and when there are multiple detection quantities required for verification, the electrical measurement board can obtain at least one of the detection quantities;

[0145] The second signal connection position is configured to be combinable or replaceable with the first module configuration position, and the mainboard module and the sensor module are signal-connected; the sensor module can collect the detection quantity required for the verification, and when there are multiple detection quantities required for the verification, the sensor module can collect one of the required detection quantities;

[0146] The configuration of the sensor module is replaceable, the first module configuration position is configured with a high-voltage measurement module, and the main board module and the high-voltage measurement module are connected by signal; the high-voltage measurement module is used to measure the electrical signal loaded on the high-voltage line (for example, 220V, so it can also be called a strong electrical signal), and the high-voltage electrical signal is the detection quantity required for verification or one of them;

[0147] The third signal connection position is configured with a signal connector, which can be combined or replaced with the first module configuration position configuration and the second module configuration position configuration. The mainboard module and the signal connector are signal-connected. The signal connector can provide two or more connection lines. The mainboard module can obtain the required detection quantity or at least one of them from an external measuring device through the signal connector.

[0148] For example, the technical solution of the above specific embodiment is improved to synchronously obtain the detection amount:

[0149] A configuration combination, wherein the first module configuration position is configured with an electrical measurement board, the second module configuration position is configured with a sensor module, and the main board module is electrically connected to the electrical measurement board and the sensor module respectively;

[0150] Another configuration combination, the first module configuration position is configured with a first electrical measurement board and a second electrical measurement board, and the main board module is electrically connected to the first electrical measurement board and the second electrical measurement board respectively;

[0151] Another configuration combination, the first module configuration position is configured with a first electrical measurement board, the third module configuration position is configured with a signal connector module, and the main board module is electrically connected to the first electrical measurement board and the signal connector module respectively;

[0152] Another configuration combination, the first module configuration position is configured with an electrical measurement board and an electrical measurement output board, and the main board module is electrically connected to the electrical measurement board and the electrical measurement output board respectively;

[0153] Another configuration combination, the first module configuration position is configured with an electrical measurement output board, the second module configuration position is configured with a sensor module, and the main board module is electrically connected to the electrical measurement output board and the sensor module respectively;

[0154] The aforementioned synchronously acquired detection quantity may be a standard quantity and a calibrated quantity, based on which the mainboard module may calculate the measured error of the calibrated measuring device according to the standard quantity and the calibrated quantity;

[0155] The aforementioned synchronously acquired detection quantities can be the main detection quantities and the key influencing quantities of the main detection quantities. Based on this, the mainboard module can calculate or compensate the main detection quantity signal according to the key influencing quantities of the main detection quantities, such as pressure and ambient temperature. Specific embodiments

[0156] like Figure 6 and Figure 7As shown, a modular structure of a calibration device includes

[0157] The device housing 010 is surrounded by a chamber;

[0158] The mainboard module 100 is used to process the acquired detection quantity and is fixedly arranged in the chamber of the device housing 010;

[0159] The battery module 550 is adjacent to the mainboard module 100 and fixed in the chamber of the device housing 010. The battery module 550 is electrically connected to the mainboard module 100 to supply power to other electrical components;

[0160] The display screen 510 is preferably a touch screen, which has information input and information display functions in at least part of the area, and is used to receive the operator's touch commands and display detection quantities. It is fixed on the front side of the device casing, and the display part of the display screen 3 is exposed outside the device casing.

[0161] Located at the upper end of the chamber of the device housing 010 and above the mainboard module 100, a first module configuration position 200 is surrounded by the device housing 010 and the mainboard module 100, and correspondingly, a first module configuration position connection component 120 corresponding to the first module configuration position 200 is provided at the upper end of the mainboard module 100; in this embodiment, the first module configuration position 200 includes a layout space that is approximately rectangular, which can accommodate the layout of one or more functional circuit boards, each of which includes a group of external communication ports connected to external device signals, and an internal communication port that is adapted to be connected to the first module configuration position connection component 120; further, the functional circuit board can also be a plate-shaped module encapsulated with a circuit board.

[0162] Located at the lower end of the chamber of the device housing 010 and below the mainboard module 100, a second module configuration position 300 is surrounded by the device housing 010 and the mainboard module 100. Correspondingly, a second module configuration position connecting component 130 corresponding to the second module configuration position 300 is provided at the lower end of the mainboard module 100; in this embodiment, the second module configuration position 300 is an approximately cylindrical layout space, which can accommodate a sensor module or a high-voltage measurement module with an approximately cylindrical outer contour.

[0163] Located on the right side of the chamber of the device housing 010 and to the right of the mainboard module 100 (can also be the left side), the third module configuration position 400 is surrounded by the device housing 010 and the mainboard module 100. Correspondingly, a third module configuration position connecting component 140 corresponding to the third module configuration position 400 is provided on the right side of the mainboard module 100; in this embodiment, the third module configuration position 13 can accommodate one or more universal signal connectors, such as aviation plugs.

[0164] The modular structure of the verification device of this specific embodiment provides a universal, platform-based, modular main structure for different verification devices. For different verification devices, the above structure can be mass-produced (i.e., the same). At the same time, different signal connection modules can be selected according to specific application scenarios or customer needs. For example, in an extreme case, the verification device is used as a recording device for a single detection quantity, and the following can be selected:

[0165] A detection quantity acquisition part (functional circuit board) with a main body approximately in the shape of a rectangular parallelepiped or a plate is configured at the first module configuration position 200. The detection quantity acquisition part can be connected to the external detection device signal, and the detection quantity acquisition part is connected to the main board module signal. At this time, the detection quantity can be obtained through the detection quantity acquisition part and transmitted to the main board module. After the main board module processes the detection quantity information, the detection quantity signal is sent to the display screen for display;

[0166] Alternatively, a detection quantity acquisition unit (sensor module or high-voltage measurement module) with an outer contour approximately cylindrical is configured at the second module configuration position 300. The detection quantity acquisition unit can be connected to the corresponding detection device signal, and the detection quantity acquisition unit is connected to the main board module signal. At this time, the detection quantity can be obtained through the detection quantity acquisition unit and transmitted to the main board module. After the main board module processes the detection quantity information, the detection quantity signal is sent to the display screen for display;

[0167] Alternatively, a universal signal connector (signal connector) is configured at the third module configuration position 400 as a detection quantity acquisition unit (, the detection quantity acquisition unit can be connected to the corresponding detection device signal, and the detection quantity acquisition unit is connected to the main board module signal. At this time, the detection quantity can be obtained through the detection quantity acquisition unit and transmitted to the main board module. After the main board module processes the detection quantity information, the detection quantity signal is sent to the display screen for display.

[0168] Correspondingly, for other signal connection positions, if no signal connection portion is configured, that is, the signal connection position is vacant, a shielding portion can be provided at a position where the signal connection position is connected to the surface of the verification device, so that the vacant signal connection position is not exposed on the surface of the verification device, for example:

[0169] If the first module configuration position is vacant, the outer contour of the shielding part can be the same as or similar to the outer contour of the detection quantity acquisition part on the surface of the verification device. From the outside of the verification device, the main difference between the two is that there is no signal connection port on the shielding part, while the detection quantity acquisition part is provided with a signal connection port on the surface of the verification device for the external detection device to connect; improved or alternatively, the detection quantity acquisition part configured in the first module configuration position is split into a shell part and a functional part during processing. When the first module configuration position needs to be vacant, only the aforementioned shell part is installed, and a film is applied to the shell part. Since the film is a commonly used and low-cost general material, it is equivalent to opening a mold once (the aforementioned shell part) and can be applied to two scenarios, saving mold costs and reducing processing complexity;

[0170] If the second module configuration position is vacant, the shielding portion may be a plate-shaped body, and the outer contour of the plate-shaped body is larger than the communication port of the second module configuration position at the bottom of the verification device;

[0171] If the third module configuration position is vacant, the shielding portion may be a plate-shaped body, and the outer contour of the plate-shaped body is larger than the communication port of the third module configuration position at the bottom of the verification device;

[0172] As an improvement to the above-mentioned solution, if necessary, the shielding portion arranged at the first module configuration position and / or the second module configuration position and / or the third module configuration position can be detachably fixed. Specific embodiments

[0173] The technical solution of this specific embodiment is an improvement on the aforementioned specific embodiment, specifically, mainly on the first module configuration position and its configuration and connection structure.

[0174] Part of the description of the first and second specific embodiments has been described, and this specific embodiment will not repeat it. Those skilled in the art may select a feasible technical solution and combine it with the technical solution of this specific embodiment.

[0175] The mainboard module is provided with a connecting component for adapting to the first module configuration position at one end facing the first signal position. The connecting component is connected to the internal signal of the mainboard module. When the signal connection part is installed to the first module configuration position, the internal signal connector of the signal connection part and the connecting component of the aforementioned mainboard module are aligned and connected to achieve the signal connection between the signal connection part and the mainboard module. Typically, the internal signal connector of the signal connection part can be a plug (row), and the aforementioned connecting component includes an adapted socket. One of the advantages of this design is that after the main body of the verification device is installed, the signal connection part can be replaced without disassembling the machine.

[0176] The first module configuration position can be set up with a larger space to accommodate multiple signal connection parts with different functions. From the perspective of universality, for different product scenarios, it is desired to realize batch design and manufacturing of the mainboard module part. Therefore, this specific embodiment is further optimized as follows.

[0177] The connection component includes multiple connection sockets (which can also be plugs. For the convenience of reading, in the subsequent description of this specific implementation technical solution, if there is no special emphasis, the applicable socket may also be a plug). The layout position of each connection socket is different, and the plugging direction of each connection socket is the same. Furthermore, the specific distribution position of each connection socket can be adjusted according to the functional use of the connection socket. For example, the connection sockets used for the external signal output of the mainboard module can be arranged adjacent to each other, and the connection sockets used for the external signal input of the mainboard module can be arranged adjacent to each other. In another way, the specific distribution position of each connection socket can be adjusted according to the type of the connection socket, that is, the connection sockets of the same type / using the same communication protocol are arranged adjacent to each other, and the connection sockets of different types / using different communication protocols are arranged separately.

[0178] In the optimized arrangement scheme of the connection sockets of the aforementioned connection assembly, the arrangement positions of each connection socket are different, and the plugging directions are the same. Specifically, the plugging directions of each connection socket are all directly opposite to the first module configuration position. The advantages of this design are:

[0179] The arrangement positions of the connection sockets are different, and the signal connection parts can be plugged into multiple connection sockets at the same time without interfering with each other, and there is no need to adjust the mainboard module design due to the different signal connection parts;

[0180] The same plug-in direction can further improve the convenience of installation. There is no need to consider different installation methods due to different signal connection parts. This is also one of the purposes of choosing the socket / plug method for adapter connection.

[0181] Based on the arrangement of the connection sockets of the aforementioned connection component, each connection socket corresponds to a certain space of the first module configuration position, and the signal connection part can be arranged correspondingly in this space. Therefore, the first module configuration position can accommodate one or more signal connection parts, and each signal connection part is adapted to be connected with a connection socket of the connection component. For example, there are three connection sockets:

[0182] A signal connection portion can be arranged on one connection socket, leaving the other two connection sockets idle;

[0183] Signal connection parts can be arranged on two connection sockets, leaving the other connection socket idle;

[0184] Signal connection parts can be arranged on the three connection sockets;

[0185] Furthermore, if the connection sockets have different functions, uses, communication protocols, etc., then typically, a specific type of signal connection part can only be set and adapted to connect to one or two connection sockets;

[0186] Since the connection components are universally configured, for different verification device products, different signal connection parts can be selected and product assembly can be achieved without replacing the mainboard module, which can greatly improve manufacturing efficiency and reduce manufacturing costs.

[0187] For the optimized design of the connection socket layout, each connection socket should make full use of the layout space as much as possible;

[0188] like Figure 8 As shown, the first module configuration position connection component 120 includes three plug-in terminals (121, 122, 123), wherein the first plug-in terminal 121 is close to the front of the device housing, the third plug-in terminal 123 is close to the back of the device housing, and the second plug-in terminal 122 is located between the first plug-in terminal 121 and the third plug-in terminal 123 in the front-to-back direction;

[0189] Alternatively, the three plug ends have different rectangular longitudinal distribution positions, and one plug end is close to the left side of the device housing, another plug end is close to the right side of the device housing, and the third plug end is located between the aforementioned two plug ends;

[0190] Alternatively, the three plug terminals are similar to a combination of the above two situations.

[0191] Furthermore, considering that the arrangement requirements of the signal connection part corresponding to a certain type / functional connection socket are different, based on the above-mentioned improvement scheme, the following options may be selected:

[0192] The connection socket can be further away from the space of the first module configuration position, thereby leaving more layout space for the functional circuit board;

[0193] The connection socket can be inserted deeper into the space of the first module configuration position, so that a shorter functional circuit board can also be adapted and connected to the connection socket;

[0194] There may be an elastic and movable connection between the connecting socket and the mainboard module. For example, an elastic member is provided between the connecting socket and the mainboard module. When the elastic member is fully extended, the connecting socket can be inserted into the first module configuration position space to a certain depth. Correspondingly, when the functional circuit board is shorter, since the connecting socket is inserted into the first module configuration position to a certain depth, it can also be adapted and connected with the functional circuit board. When the functional circuit board is larger, the elastic member can also be compressed to ensure the layout space of the functional circuit board. Specific embodiments

[0195] This specific embodiment improves upon the aforementioned specific embodiments, and shows a feasible combination configuration scheme of feasible verification modules (functional circuit board, sensor module, high-voltage measurement module, signal connector) based on the aforementioned verification device main structure / verification device modular structure.

[0196] This specific embodiment emphasizes that:

[0197] First, unlike general signal connections, in this specific embodiment, the verification module is not randomly selected. For example, for the first module configuration position 200 and the second module configuration position 300, an electronic component with a matching appearance is not randomly selected for plugging. As described in the above specific embodiments, only the functional circuit board is suitable for configuration in the first module configuration position 200, and only the sensor module or the high-voltage measurement module is suitable for configuration in the second module configuration position 300, because this can meet the verification requirements;

[0198] Secondly, unlike general signal connections, in this specific embodiment, the verification module is not arbitrarily configurable. For example, the sensor module / high-voltage measurement module / signal connector cannot be configured in the first module configuration position 200, because from a structural design point of view, the mainboard module does not have an adaptable connection structure set at the first module configuration position 200.

[0199] In a feasible example, at least one of the first module configuration bit, the second module configuration bit and the third module configuration bit is configured with a detection quantity acquisition module, and the mainboard module is connected to the detection quantity acquisition module signal through a connector, and the so-called detection quantity acquisition module includes:

[0200] A functional circuit board that can obtain and measure electrical signals from the outside;

[0201] A high-voltage measurement module that can obtain and measure electrical signals from the outside;

[0202] A sensor module that can measure and collect specific detection quantities;

[0203] A signal connector that can obtain electrical signals from the outside and transmit them to the mainboard module.

[0204] Specifically, the functional circuit board includes an electrical measurement board, an electrical output board and a measurement output board. Further subdivided, the electrical measurement board can be divided into a general electrical measurement board and a temperature measurement board.

[0205] Generally, the electrical measurement board has a measurement circuit corresponding to the measurable signal configured on the circuit board. Specifically, the general electrical measurement board can measure one or a combination of voltage, current, frequency, pulse, switch, loop current, and HART.

[0206] For example, a general electrical measurement board includes a current measurement circuit, a current signal input terminal electrically connected to the current measurement circuit, a voltage measurement circuit, a voltage signal input terminal electrically connected to the voltage measurement circuit, a pulse measurement circuit, a pulse signal input terminal electrically connected to the pulse measurement circuit, a switch quantity measurement circuit, a switch signal input terminal electrically connected to the switch quantity measurement circuit, an information processing element and a signal output terminal. The information processing element is respectively connected to the current measurement circuit, the voltage measurement circuit, the pulse measurement circuit, the switch quantity measurement circuit and the signal output terminal. At this time, the electrical measurement board has the measurement function of four signals: voltage, current, pulse and switch. When working, the external signal source is electrically connected to the corresponding signal input terminal. The general electrical measurement board is connected to the main board module through the signal output terminal. When an external analog signal is input, the electrical signal is received through the corresponding signal input terminal. The corresponding signal measurement circuit measures the signal and transmits the measurement result to the information processing element. The information processing element processes the measurement result and transmits the obtained digital signal to the main board module through the signal output terminal.

[0207] The temperature measurement board is similar to the general electrical measurement board. The temperature measurement board also includes an analog signal measurement circuit, an analog signal input terminal, an information processing component, and a digital signal output terminal. The difference from the general electrical measurement board is:

[0208] The temperature measurement board is provided with a cold end temperature detection circuit, which includes a temperature sensor or other temperature acquisition element, and the cold end temperature detection circuit is connected to the information processing element signal;

[0209] According to different measurement objects, the signal input end of the temperature measurement board includes a thermocouple signal input end and a thermal resistor signal input end, and a voltage measurement circuit is electrically connected to the thermocouple signal input end, and a resistance measurement circuit is electrically connected to the thermal resistor signal input end;

[0210] When the temperature measurement board outputs a signal to the main board module, it not only outputs the detection value obtained by the measurement circuit, but also outputs the cold end signal value obtained by the cold end temperature detection circuit. When the object to be measured is a thermocouple, the main board module calculates the temperature based on the cold end signal value and the thermocouple detection value. For details, please refer to the following formula 1;

[0211] E(t m ,t c )=E(t m ,0)-E(t c ,0) Formula 1

[0212] In formula 1, the corresponding relationship between E(t,0) and t can be obtained by looking up the thermocouple graduation table, t m Indicates the measured temperature value, t c Indicates the cold end temperature value, E(t m,t c ) is the thermoelectric electromotive force value input through the thermocouple signal input terminal, which can be measured by the voltage measurement circuit. c It can be measured by the cold end temperature detection circuit, so E(t c ,0), and then we get E(t m ,0), and then the measured temperature value can be obtained by looking up the table; the thermocouple graduation table can be configured on the temperature measurement board, that is, the temperature measurement board can independently complete the calculation of the temperature quantity and output the measured temperature value to the main board module; the thermocouple graduation table can also be configured on the main board module, that is, the main board module and the temperature measurement board jointly complete the calculation of the measured temperature value.

[0213] An electrical output board, on which a signal generating circuit capable of generating a corresponding analog signal is disposed, specifically, the electrical output board can output one or a combination of voltage, current, frequency, pulse, switch, loop current, and HART;

[0214] For example, the electric output board includes a current generating circuit, a current signal output terminal electrically connected to the current generating circuit, a voltage generating circuit, a voltage signal output terminal electrically connected to the voltage generating circuit, a pulse signal generating circuit, a pulse signal output terminal electrically connected to the pulse signal generating circuit, a frequency signal generating circuit, a frequency signal output terminal electrically connected to the frequency signal generating circuit, an information processing element and a signal input terminal. The current generating circuit, the voltage generating circuit, the pulse signal generating circuit, the frequency signal generating circuit and the signal input terminal are respectively connected to the information processing element by signal. At this time, the electric output board has the generation and output functions of four signals: voltage, current, pulse and frequency. When working, the electric output board is electrically connected to the main board module through the signal input terminal. The main board module sends a signal generation instruction to the electric output board according to the instruction. After the information processing element obtains the instruction of the main board module, it sends the electrical signal of the information processing element to the corresponding analog signal generating circuit. The analog signal generating circuit generates a corresponding analog electrical signal according to the electrical signal of the information processing element, and outputs it to the outside through the corresponding analog signal output terminal.

[0215] Measurement output board, generally, the measurement and output of the measurement output board are for the same detection quantity;

[0216] For example, a temperature measurement output board includes an information processing element, an internal signal interaction terminal and a cold end temperature detection circuit, the temperature measurement output board is connected to the main board module signal through the internal signal interaction terminal, and the information processing element is electrically connected to the internal signal interaction terminal and the cold end temperature detection circuit respectively;

[0230] The signal connector may adopt common signal connection components such as aviation plugs, which will not be described in detail here.

[0231] Furthermore, this specific embodiment emphasizes that, even when the above two points are met, the configuration of the verification module is not a random combination. This specific embodiment further provides a feasible verification module combination based on the same modular architecture as follows.

[0232] For example, Fig. 9 As shown, the pressure calibrator includes the device housing.

[0238] The mainboard module 100 corresponds to the first module configuration position 200, and is provided with a first plug-in terminal 121, a second plug-in terminal 122 and a third plug-in terminal 123, wherein the first plug-in terminal 121 and the mainboard module are coplanar, the second plug-in terminal 122 and the third plug-in terminal 123 are extended toward the back side of the pressure calibrator through a connecting element perpendicular to the mainboard module, and the first plug-in terminal 121, the second plug-in terminal 122 and the third plug-in terminal 123 are parallel to each other and located in different planes;

[0239] The device rear shell 012 corresponds to the first module configuration position 200, and is provided with a first installation slot 021, a second installation slot 022 and a third installation slot 023, each of which (021, 022, 023) is a symmetrically arranged slot extending in the up-down direction, wherein the slot position of the first installation slot 021 corresponds to the first plug-in end 121 on the mainboard module, so that the functional circuit board inserted through the first installation slot 021 is coplanar with the first plug-in end 121, similarly, the slot position of the second installation slot 022 corresponds to the second plug-in end 122 on the mainboard module, and the slot position of the third installation slot 023 corresponds to the third plug-in end 123 on the mainboard module;

[0240] The upper shell 013 of the device corresponds to the first module configuration position 200, and is provided with a first external signal port 031, a second external signal port 032 and a third external signal port 033, wherein the arrangement position of the first external signal port 031 corresponds to the first plug-in terminal 121 on the mainboard module, so that the first external signal port 031 and the first plug-in terminal 121 are coplanar or approximately coplanar, the arrangement position of the second external signal port 032 corresponds to the second plug-in terminal 122 on the mainboard module, and the arrangement position of the third external signal port 033 corresponds to the third plug-in terminal 123 on the mainboard module;

[0241] Further Fig.10 As shown, the inner side of the upper shell 013 of the device (i.e., the side facing the first module configuration position) is provided with a first slot 041, a second slot 042 and a third slot 043, and the slots (041, 042, 043) are arranged parallel to each other, wherein the slot position of the first slot 041 corresponds to the first plug-in terminal 121 on the mainboard module, and the first external signal port 031 falls into the bottom of the slot of the first slot 041, so that the first slot 041 and the first plug-in terminal 121 are coplanar or approximately coplanar, the slot position of the second slot 042 corresponds to the second plug-in terminal 122 on the mainboard module, and the second external signal port 032 falls into the bottom of the slot of the second slot 042, the slot position of the third slot 043 corresponds to the third plug-in terminal 123 on the mainboard module, and the third external signal port 033 falls into the bottom of the slot of the third slot 043.

[0242] In this example, the first module configuration position 200 is used for obtaining the pressure signal, and only the electric measuring board (general electric measuring board) 620 is arranged. The upper end of the electric measuring board 620 is inserted into the second slot 042, so that the signal input end of the electric measuring board 620 can overlap with the second external signal port 032. When the upper shell 013 of the device is adapted and fixed on the rear shell 012 of the device, the two sides of the electric measuring board 620 fall into the second installation grooves 022 on the two sides of the rear shell 012 of the device, and the signal output end of the electric measuring board 620 is located at the lower end of the electric measuring board 620.

The signal connector 540 is adaptably connected to the third module configuration position connection component 140 arranged at the upper right part of the mainboard module 100.

[0245] Another example is a pressure calibrator. The difference from the previous example is that the pressure calibrator in this example is not configured with a signal connector in the area of ​​the third module configuration position 400, so that the third module configuration position 400 becomes vacant.

[0246] The solution of this specific embodiment can not only realize multiple types of product configurations in products belonging to the same pressure calibrator (for example, configuring electrical measurement modules 620 with different functions, configuring pressure sensor modules 520 with different accuracy, thereby forming pressure calibrators of different models), but also based on the same set of modular architecture, different products can be realized through feasible calibration module combinations.
