Description

Intelligent pressure gauge

Technical Field

The invention relates to the technical field of pressure measurement and detection, in particular to an intelligent pressure gauge.

Background

The integration of 'lean, informatization and automation' is the development direction of industrial manufacturing and is the necessary route from traditional industrial manufacturing to intelligent manufacturing. As one of key parameters in industrial production, pressure measurement is widely required in each link of an industrial process, as a main device of pressure measurement, pressure parameters are simply measured and displayed, the requirement of the current intelligent manufacturing environment on a pressure gauge cannot be met, and the pressure gauge is typically required to have stronger interactivity as a detection terminal.

Generally speaking, the stronger interactivity requires that the pressure gauge not only has clearer visibility and better observation effect, but also has operability which is more in accordance with the ergonomic requirement, more convenient and intelligent.

From the perspective of visibility, compared with a smaller display area, the larger display area can always contain more display information and can be observed more conveniently, namely the display area of the pressure gauge is required to be as large as possible; in the prior art, whether the pressure gauge is a pointer pressure gauge (i.e. the dial is in the form of a scale dial and a pointer indication), or a general digital pressure gauge, since the size of the dial of the pressure gauge has corresponding specifications, such as 60mm, 100mm, and the like, logically, when the size of the dial is determined, in order to make the display area of the pressure gauge, the occupied area of the display area in the dial is required to be as large as possible.

In different scenes, the pressure gauge may need to be operated and controlled, typical operations including confirmation, return, selection of up, down, left and right, and some functions (such as zero point self-calibration) which are very common in the pressure measurement process are all required in the pressure gauge operation process, in addition, keys arranged on a dial (positioned on the front surface of the gauge head) are most consistent with the operation habit, the operation difficulty of the keys arranged on the side surface of the gauge head is greatly increased, the keys arranged on the back surface of the gauge head cannot be basically operated in real time, for example, as shown in fig. 1, a digital pressure gauge is provided in the prior art, 11 keys 01 are arranged on the front surface of the gauge head for auxiliary operation, and therefore, the display area 02 of the display screen is very small.

The above factor constraints cause the display area and the key area to compete within a limited range of the pressure gauge dial, and it is obvious that, no matter how to adjust, the area where the key is set is obviously not able to display, the area for displaying obviously has no key, more extreme, in order to set the key, the display area of the dial needs to be reduced, when pressure measurement is performed, the size of the displayed form is reduced, visibility is reduced, disposable display content is reduced, functionality is reduced, and at the other extreme, in order to display pressure measurement information, the key area needs to be reduced.

In order to solve the problem of competition of the limited display and control area, a wireless digital pressure gauge is proposed in the prior art, in order to solve the key contradiction, the control mode is converted into a mode of three setting parameters, namely infrared or Bluetooth configuration under a screen, waterproof wired connection configuration and remote configuration, namely a control end is additionally provided during work, and the design scheme releases the dial area to the greatest extent so as to display more contents; on one hand, on the other hand, the operation needs to be carried out again through remote connection configuration before the control, so that the operation difficulty is increased, and conceivably, when the display of a certain pressure gauge is only required to be refreshed to quickly confirm the current pressure value, the connection needs to be configured, the connection is waited to be completed, and the control is carried out again, so that the purposes of simple refreshing and quick confirmation expected by an operator are obviously deviated; on the other hand, the pressure gauge can only be used as a display terminal in the state, and cannot be controlled, so that the requirement of intelligently manufacturing an expected display and control integrated detection terminal cannot be met; on the other hand, the control and the display are separated, so that great interference is brought to operation control, and it is conceivable that an external keyboard (such as a television remote controller) is taken as an example, when two or more different inputs participate in operation, an operator needs to firstly look at the keyboard, confirm a needed first key, look up the display of the pressure gauge after pressing, look up a needed second key according to the display of the pressure gauge, and look up the display of the pressure gauge after pressing, so that the operation difficulty is very high.

Detailed description of the preferred embodiment

The control module is configured to read pressure measurement data from the pressure module through the first data channel, generate a pressure indication value display instruction after processing and send the pressure indication value display instruction to the touch display screen, and the pressure indication value display instruction reaches the touch display screen through the second data channel to enable the pressure indication value to be displayed in the touch display screen.

The gauge outfit is internally and fixedly provided with a detachable and replaceable Bluetooth module, and a third data channel is formed by the electric connection between the Bluetooth module and the control module.

In this example, in order to enable the intelligent pressure gauge to be applied to various working conditions, a digital metering display model and a pointer display model are preset in the control module.

The digital metering display model is configured by a control module and a touch display screen in a linkage manner, and specifically, a pressure indicating value display instruction generated by the control module comprises a pressure indicating value part embodied in a digital form and a pressure indicating value unit part embodied in a character form, so that the touch display screen displays a pressure indicating value in a main display area at least comprising the middle part; the digital metering model is suitable for steady-state and static metering of pressure, for example, a certain stable pressure value needs to be measured, and the current pressure value can be read relatively easily.

The pointer display model is configured by the linkage of the control module and the touch display screen, and particularly, the control module can preset one or more scale dial display models, each scale dial display model corresponds to a determined range and can be set to provide a range instruction for the control module, the control module is configured to call the corresponding preset scale dial display model according to the range instruction and send the preset scale dial display model to the touch display screen, so that the touch display screen displays the scale dial corresponding to the range instruction at least in a main display area comprising the middle part, further, the control module is configured to calculate the pointer position according to the range and pressure measurement data and generate a pressure indication value display instruction according to the pointer position, so that the pressure indication value indicated by a pointer indication part in the touch display screen corresponds to the pressure measurement data; the pointer display model is suitable for fast and dynamic measurement of pressure, such as the change of a certain pressure value.

In order to further meet the possible working condition requirements, a first digital metering mode, a second digital metering mode and an indicator metering mode are preferably configured for the intelligent pressure gauge.

In an example, the intelligent pressure gauge is in a first digital metering mode in an initialization posture, and correspondingly, a first digital metering display model is preset in the control module.

In the first digital metrological display model, as shown in fig. 6, the control module is configured to divide the touch display screen into a first display area 321, a second display area 322, and a third display area 323, the first display area 321 being located in the middle of the display portion of the touch display screen and occupying a larger area of the display portion, the second display area 322 being located above the display portion of the touch display screen and occupying a smaller area of the display portion, and the third display area 323 being located below the display portion of the touch display screen and occupying a smaller area of the display portion.

The control module is configured to cause the first display area 321 of the touch screen display to display a pressure indication, in this embodiment, the preset range is 1.6MPa and the unit is kPa, the control module is configured to periodically read the pressure measurement data from the pressure module through the first data channel and process the pressure measurement data according to the preset unit to form a pressure indication, the pressure indication is in the form of "XXX kPa" and has a size between 0MPa and 7MPa, and preferably, the pressure indication is configured to be displayed in a larger font in the first display area (because only a single pressure indication needs to be displayed in the first display area in the first digital measurement display model).

The control module is configured to make the second display area 322 display the battery identifier and the bluetooth identifier, and in this embodiment, the control module is configured with a battery identifier form corresponding to different electric quantities, for example, a battery electric quantity read according to a full charge degree in the battery identifier corresponds to a full battery identifier when the battery electric quantity is full, and a battery identifier without filling and with a diagonal line when the battery electric quantity is extremely low (for example, less than or equal to ten percent); similar to the battery power, the control module is configured with bluetooth identifier forms corresponding to different bluetooth module working states, for example, when the bluetooth module is not powered on and started (corresponding to the fact that the bluetooth module has no response to the interactive verification of the control module, therefore, when the bluetooth module fails, the bluetooth identifier forms corresponding to the identifier state), the bluetooth identifier is corresponding to a bluetooth identifier with dark or transparent color, when the bluetooth module is started and has no network connection (corresponding to the fact that the bluetooth module only returns self-checking data and has no network access checking feedback when the control module requires verification), the bluetooth identifier which is lightened and completely filled is correspondingly lightened and fully filled, when the bluetooth module is started and is in pairing connection with other equipment, the lightened and fully filled bluetooth identifier is displayed, and the short for pairing connection equipment is also displayed beside the bluetooth identifier; based on the above arrangement, the control module is configured to periodically read power information (which may also be information capable of representing power, such as battery voltage) from the battery module, and periodically perform data interaction with the bluetooth module through the third data channel, determine an on state (whether power is on or off) and a network connection state (whether pairing connection is established with other devices) of the bluetooth module, determine a battery identifier form according to the read battery power information, and determine a bluetooth module form according to the read bluetooth module interaction condition.

Alternatively, since the battery power and the bluetooth status are both unnecessary functions of the smart pressure gauge, the period during which the control module reads the power information and the period during which the control module and the bluetooth module perform data interactive verification may be a longer and fixed period, which corresponds to the longer and fixed period, and the reading of the pressure measurement data by the control module is a key function of the smart pressure gauge, so the period corresponding to the reading of the pressure measurement data and the displaying of the pressure indication value may be a shorter and configurable period, for example, the control module may be configured to perform pressure measurement data reading at a frequency of 5Hz (i.e., 0.2s per period) or faster, and the acquisition frequency of such pressure measurement data is adjustable within a certain range, and the control module may be fixedly configured to read the battery power and the bluetooth status every 3 s.

The control module is configured to cause the third display area 323 to display the control instruction icon.

When the intelligent pressure gauge is in a first digital metering mode, based on the above description, the control module is configured to periodically read pressure metering data and periodically read battery capacity and a bluetooth state, the control module generates a first digital metering display instruction according to the read information and a preset first digital metering display model, and sends the first digital metering display instruction to the touch display screen through a second data channel, and the touch display screen receives the first digital metering display instruction and generates actions to enable the touch display screen to display a battery and a bluetooth identifier in a smaller area at the uppermost part (namely, a second display area), display a pressure indication value in a larger area at the middle part (namely, the first display area), and display a control instruction icon in a smaller area at the lowermost part (namely, a third display area); when the intelligent pressure gauge continuously keeps the first digital metering mode, the control module reads pressure metering data and updates pressure indication value display in a short period, the control module reads battery electric quantity and Bluetooth states in a long period, display updating of the battery identification and the Bluetooth identification occurs only when a new display identification corresponds, and the control module does not update display of the third display area.

The first digital metering mode is suitable for general static metering, and in the first digital metering mode, in order to meet metering requirements, touch screen control is received, and the control module can respond according to preset.

When the touch display screen is touched in a click mode, the touch display screen generates a touch instruction, the touch instruction is transmitted to the control module through the second data channel, and the control module is configured to identify the position where the touch instruction is generated:

if the touch instruction is generated in the first display area, the control module is configured to read the pressure measurement data and generate a pressure indication value to be displayed in the first display area immediately after the touch instruction is generated in the first display area; one of the advantages of the design is that because the first display area occupies a larger area of the touch display screen, if mistaken touch occurs in the operation process, the probability occurs in the first display area, and the refreshing display of the pressure indication value has no adverse effect on normal pressure measurement, so that the problem of misoperation is avoided as much as possible under the condition that the screen is fully controllable; another advantage of this design is that analysis is performed in combination with the conditions in the metering field and ergonomics, typically, when the pressure is stable in the static metering process, when the indication value of the pressure gauge is not changed, a requirement for manual refreshing display is generated to ensure that the change of the indication value of the pressure is real and effective rather than caused by a failure that the response is not timely performed, the problem is solved by manual tapping in the operation of the original mechanical pressure gauge, and the digital pressure gauge does not have the problem of mechanical delay/clamping, but may have a crash or the like, so that the design of this example not only meets the metering requirement for pressure refreshing, but also has a proximity between click touch and manual tapping, and is more suitable for the operation habit by combining touch at the position where the indication value of the pressure is displayed;

if the touch instruction is generated in the second display area, similar to the fourth embodiment, the control module is preset with a status display model, in the status display model, the control module is configured to enable the first display area and the second display area to display more detailed battery power information and bluetooth connection information in a combined manner, for example, the remaining percentage of the battery power, the estimated remaining usage time, the full name of devices connected in bluetooth pairing, other bluetooth devices capable of being paired, and the like are displayed, and the control module is configured to display a return instruction icon in the third display area; specifically, the control module receives a touch instruction, generates a state display instruction according to the state display model, and transmits the state display instruction to the touch display screen through the second data channel and displays the state display instruction in the touch display screen; further, on the basis of displaying the detailed state information, if a touch instruction occurs in the third display area, namely the return instruction icon display area, the control module receives the touch instruction and returns the intelligent pressure gauge to the first digital metering mode according to the first digital metering display model;

if the touch instruction is generated in the third display area, the control module is preset with a metering control display model, and in the embodiment, the process needing metering control comprises range setting, pressure acquisition frequency setting, pressure unit setting and the like; on the basis, the control display model comprises a two-level interface, the control display module controls and displays the one-level interface, the control module enables the touch display screen to keep the state display of the pressure gauge (namely a battery identifier and a Bluetooth identifier) in a second display area, enables the touch display screen to display a return instruction icon in a third display area, and enables the touch display screen to display a range setting identifier, a pressure acquisition frequency setting identifier and a pressure unit setting identifier in the first display area in a non-overlapping manner; furthermore, when a secondary touch instruction occurs in a pressure unit setting identification area, the control module enables the touch display screen to enter a control display secondary interface (pressure unit setting), enables the touch display screen to display each selectable pressure unit and a confirmation identification in the first display area, enables a tertiary touch instruction to occur in the selectable pressure unit and can set the pressure indicating value unit, enables the tertiary touch instruction to occur in the confirmation identification and can store and confirm the currently selected pressure indicating value unit, and enables the tertiary touch instruction to occur in the third display area and can return to control display of the primary interface and keep the originally stored pressure indicating value unit setting unchanged; in another further scheme, when a secondary touch instruction occurs in a pressure acquisition frequency setting identification area, the control module enables the touch display screen to enter a control display secondary interface (pressure acquisition frequency setting), enables the touch display screen to display a digital input interface and a confirmation identification in a first display area, performs touch control based on the digital input interface, can input expected acquisition frequency within an allowable range and confirm through touching the confirmation identification, generates a touch instruction in a third display area, and can directly return to the control display primary interface and keep the original stored acquisition frequency setting unchanged; in another further scheme, when the secondary touch instruction occurs in the range setting identification area, the control module enables the touch display screen to enter a control display secondary interface (range setting), enables the touch display screen to display each selectable range and a confirmation identification in the first display area, is similar to the pressure unit setting, and also comprises operations of selectable setting, confirmation setting, setting abandon and return and the like in the range setting interface.

Different from various settings (such as click-type touch and corresponding touch instructions in the first display area, the second display area and the third display area as described above) in the first digital metering mode, the touch display screen and the control module are linked and can respond to screen sliding control of the touch display screen for switching among different metering modes.

In the first digital metering mode, screen sliding touch occurs on the touch display screen, the touch display screen generates a sliding control instruction, the sliding control instruction is transmitted to the control module through the second data channel, the control module receives the sliding control instruction and responds, further, in the embodiment, the first digital metering mode, the second digital metering mode and the pointer metering mode are sequenced, the control module is configured to switch the metering modes in sequence when the position generated by the sliding control instruction is from left to right or from top to bottom, and switch the metering modes in reverse sequence when the position generated by the sliding control instruction is from right to left or from bottom to top.

In the first digital metering mode, the touch display screen generates a left-to-right sliding control instruction, and the intelligent pressure gauge is switched to the second digital metering mode.

Similar to the first digital metering mode, in the second digital metering mode, as shown in fig. 7, the control module is also preset with a second digital metering display model, so that the touch display screen displays pressure metering information in the first display area 321, displays a pressure gauge state identifier (a battery identifier and a bluetooth identifier) in the second display area 322, displays a control instruction identifier in the third display area 323, reads and displays and refreshes pressure metering data when a secondary touch instruction is generated in the first display area, displays and operates according to the state display model when a secondary touch instruction is generated in the second display area, and displays and operates according to the metering control display model when a secondary touch instruction is generated in the third display area.

What is different from the first digital metering mode is that, in the second digital metering display model, as shown in fig. 7, the control module is configured to simultaneously display a pressure indication value and an electrical measurement value in the first display area 321, the pressure indication value and the electrical measurement value at the same time correspond to the same pressure metering data from the pressure module, and the difference between the two is that the pressure indication value is secondarily processed by the control module, so that the pressure condition to be measured can be conveniently and intuitively directly read, the electrical measurement value is the pressure metering data directly transmitted to the control module by the pressure module, and the output condition of the pressure module can be conveniently and intuitively read.

The purpose of the second digital metering mode is that the intelligent pressure gauge of the example is used as a standard device to simultaneously check the pressure transmitter and the pressure gauge, and the example is that when the pressure device to be checked is the pressure transmitter, an electrical indicating value is used as a standard value, and when the pressure device to be checked is the pressure gauge, the pressure indicating value is used as a standard value, and the whole process does not need to be calculated and converted.

And under the second digital metering mode, if the touch display screen generates a right-left sliding control instruction, the intelligent pressure gauge is switched to the first digital metering mode.

Similar to the switching between the first digital metering mode and the second digital metering mode, in the second digital metering mode, if a touch display screen generates a sliding control instruction from left to right, the intelligent pressure gauge is switched to the pointer metering mode; and under the pointer metering mode, if the touch display screen generates a right-left sliding control instruction, the intelligent pressure gauge is switched to a second digital metering mode.

The control module is preset with a pointer metering display model, in the pointer metering display model, the control module is configured to merge the first display area and the second display area of the touch display screen into a main display area 324, and display an analog scale dial plate and an analog pointer in the main display area 324, the scale range of the analog scale dial plate is based on a preset range, the position of the analog pointer is based on the preset range and pressure metering data, the preset range is 0.6MPa, in the corresponding pointer metering display model, the control module is configured to enable the touch display screen to start from the left lower area in the main display area 324, and uniformly distribute a plurality of scale values along the left lower area, the left middle area, the left upper area, the right middle area and the right lower area, wherein the scale values comprise seven main scale lines of displaying thinner 0.05 MPa, 0.1MPa, 0.2 MPa, 0.3 MPa, 0.4MPa, 0.5 MPa and 0.6MPa, and the main scale lines displaying thinner 0.05 MPa, thinner 0.1MPa, The pressure value corresponding to pressure metering data read by the control module from the pressure module is 0MPa, and according to the pressure value and the preset range, the control module is configured to generate pointer position display information to enable the touch display screen to display a virtual pointer at a position indicating 0 MPa; the control module is configured to cause the third display area 323 of the touch display screen to display the control instruction identification.

Similar to the switching between the first digital metering mode and the second digital metering mode, in the pointer metering mode, when a secondary touch instruction is generated in the third display area, the display and the operation are carried out according to the metering control display model.

The pointer metering mode is different from the digital metering mode in that the control module enables the main display area of the touch display screen to display the scale dial with different ranges when the preset ranges are different, and the display of the scale dial and the pointer is basically not influenced by different pressure units when the preset ranges are fixed.

In an example, a method for using the pressure gauge of this example, under a possible working condition, there are a plurality of pressure points to be measured, and observation requirements of different pressure points to be measured are different:

the first pressure point to be measured requires that the upper limit value of the pressure to be measured is lower than 10 MPa;

the second pressure point to be measured requires that the upper limit value of the pressure to be measured is lower than 7 MPa;

a third pressure point to be measured, wherein the upper limit value of the pressure to be measured is required to be lower than 1.6 MPa;

the fourth pressure point to be measured requires that the pressure to be measured is within the range of 0.6MPa +/-0.1 MPa;

and the fifth pressure point to be measured requires that the pressure to be measured is within the range of 400kPa +/-10 kPa.

If a general digital pressure gauge is adopted, from the viewpoint of human engineering, an operator needs to read pressure data one by one, compare the pressure data with a threshold value and then determine a result, and obviously, as a plurality of points to be measured have different requirements on different points to be measured, the logic judgment is very difficult and is easy to make mistakes; in addition, in the process, if abnormal pressure fluctuation occurs at a certain pressure point to be measured, the operator can hardly find the abnormal pressure fluctuation, because the digital change is not specific in the human brain in an abstract way, and the digital change is not easy to find for the operator unless the digital change is particularly large.

Five pressure gauges of this example were configured, a first pressure gauge was connected to a first pressure point to be measured and set in a pointer measurement mode with a range of 10MPa, a second pressure gauge was connected to a second pressure point to be measured and set in a pointer measurement mode with a range of 7MPa, a third pressure gauge was connected to a third pressure point to be measured and set in a pointer measurement mode with a range of 1.6MPa, a first pressure gauge was connected to a fourth pressure point to be measured and set in a pointer measurement mode with a range of 1.2MPa, a fifth pressure gauge was connected to a fifth pressure point to be measured and set in a pointer measurement mode with a range of 0.8MPa, unlike the prior art, in this example, no reading was required, the first pressure gauge/second pressure gauge/third pressure gauge needed to pay attention to whether the pointer approached/reached a full-range state, the fourth pressure gauge/fifth pressure gauge needed to pay attention to whether the pointer deviated from a middle position, in addition, generally normal pressure changes (such as slow pressure change or fluctuation in a tiny range) are hardly reflected on the image, so that the attention of an operator cannot be caused, and when abnormal pressure fluctuation (which is intuitively reflected to large change in a short time) occurs at a certain pressure point to be measured, the pressure can be obviously displayed on the image (such as rapid pointer change), so that the operator can pay attention to the response in time; in addition, as in the present example, it is not necessary to configure a plurality of pressure gauges as accuracy allows, and mass production and use are facilitated.

Detailed description of the preferred embodiment

Similar to the eighth embodiment, the intelligent pressure gauge comprises a gauge head, a pressure module, a touch display screen and a control module, wherein the touch display screen is fixedly arranged on the front surface of the gauge head; the control module is preset with a pointer metering display model, so that the touch display screen can display a virtual scale dial plate and a virtual pointer based on a preset range.

And improving on the basis of the eighth specific embodiment, in the metering control process of the embodiment, along with the configuration range, the input of the accuracy/allowable error can be further performed.

The control module is configured to adjust the display color of at least partial area of the touch display screen along with the change of the pressure measurement data in the pointer measurement mode; in the pointer metering mode, the control module calculates the position of the virtual pointer according to the pressure metering data and the preset range, and simultaneously performs the following steps:

determining a current pressure indication value according to the pressure metering data;

according to the preset range, the corresponding pressure values of the main scale marks (or the main scale marks and the secondary scale marks) in the current dial plate are determined, for example, if the preset range is 1.6MPa, the corresponding pressure values of the main scale marks are 0MPa, 0.4MPa, 0.8MPa, 1.2MPa and 1.6 MPa;

calculating the absolute value of the difference between the current pressure indication value and the pressure value closest to the main scale mark, and further comparing the absolute value with an allowable error (if the input is an accuracy value, the allowable error is calculated by combining a preset range), when the absolute value is less than or equal to the allowable error, displaying a first color which is easy to observe in a specific part area of the touch display screen, and when the absolute value is greater than the allowable error, displaying another second color which is easy to observe in the specific part area of the touch display screen, wherein the first color and the second color are obviously different; illustratively, the preset allowable error is 16kPa, i.e., 1% of the full scale (1.6 MPa), if the current pressure indication is 0.001MPa, it is determined that the pressure value closest to the main scale line is 0MPa and the absolute value of the difference therebetween is 0.001MPa, 0.001MPa < 16kPa, so that the specific partial region of the touch display screen displays the first color, if the current pressure indication is 0.380 MPa, it is determined that the pressure value closest to the main scale line is 0.4MPa and the absolute value of the difference therebetween is 0.02MPa, 0.02MPa > 16kPa, so that the specific partial region of the touch display screen displays the second color, and so on.

In an example, the scale dial is white as a whole, the scale lines therein are black, the changed color area is the area where the pointer is located, the first color is green, and the second color is red.

In another example, the scale dial is white as a whole, the pointer is black, the changed color area is the area where the scale mark is located, the first color is green, and the second color is red.

In another example, the color of the entire touch display screen changes, specifically, in the first color, the entire touch display screen is green, and the scale lines and the pointer are both black, and in the second color, the entire touch display screen is blue, and the scale lines and the pointer are both white.

Obviously, whatever the color distribution, the aim is to make the touch display screen undergo a color change that is easier to observe than a change in the position of the pointer when the pressure value is within a certain range (the absolute value is less than or equal to the permissible error) and not within a certain range (the absolute value is greater than the permissible error).

In the extended embodiment of the present embodiment, the pressure variation range may be determined by other methods, such as completely freely preset, for example, inputting 0.402MPa, 0.855MPa, etc. (these pressure values may be any values in the range of the preset range) as required, and determining the judgment range to be 50kPa or other values (not limited to the allowable error).

The color change scheme provided by the example can assist in quickly and accurately judging the pressure indication value, based on human engineering consideration, in the rough pressure value judgment (for example, the pressure value is determined to be near 0.4MPa instead of near 0.8 MPa), the image position judgment is obviously quicker than the digital judgment and is not easy to make an error, and in the fine pressure value judgment (for example, the pressure value is determined to be within the range of 0.4MPa +/-16 kPa), the color judgment is obviously quicker than the digital judgment and is not easy to make an error.

A relatively typical pressure value quick judgment application scene is provided, and a method for quickly verifying a pointer type pressure gauge by using the intelligent pressure gauge of the example comprises the following steps:

the calibrated meter comprises a pointer type pressure meter with the measuring range of 7MPa and a pointer type pressure meter with the measuring range of 1.6MPa, and the accuracy of the two pressure meters is 1 percent;

the present example smart pressure gauge with higher accuracy was used as a standard;

the pressure source comprises a pressure generator and a pressure distribution pipeline, wherein the pressure generator is used for generating pressure, the pressure distribution pipeline is internally provided with a standard interface, a calibrated interface, a pressurizing port and a pressure relief port which are communicated with each other, the pressurizing port is communicated with the pressure generator so that the pressure generator can provide pressure for the pressure distribution pipeline, a pressure module of the standard is communicated with the standard interface, and the calibrated interface is communicated with the calibrated interface; basically, closing the pressure relief port and starting the pressure generator can increase the pressure applied to the standard port and the calibrated port, closing the pressure generator and opening the pressure relief port can decrease the pressure applied to the standard port and the calibrated port until the same pressure value as the lower pressure is reached;

firstly, rapidly checking a calibrated meter with the measuring range of 1.6MPa, connecting a pressure module of a standard device into a standard interface, connecting the calibrated meter with the measuring range of 1.6MPa into a calibrated interface, and setting the positions of meter heads of the standard device and the calibrated meter to enable the standard device and the calibrated meter to be parallel and adjacent, so that the calibrated meter and the calibrated meter can be observed simultaneously;

setting a standard device, enabling the intelligent pressure gauge to enter a pointer metering mode, and enabling the preset measuring range to be 1.6MPa and the preset accuracy to be 1% (the allowable error is 16 kPa);

adjusting the pressure source to continuously change the pressure in the pressure source from 0MPa to 1.6MPa and then from 1.6MPa to 0MPa, wherein the pressure change is continuous in the whole process and a pressure stable state is not necessary;

because the range set by the standard device is the same as the calibrated meter, and the dial distribution of the calibrated meter and the calibrated meter is the same based on the normalized design specification requirement, whether the change conditions of the pointers of the calibrated meter and the standard device are the same or not can be quickly observed, the specific comparison points comprise the position of the pointer, the change amplitude of the pointer, the change direction of the pointer and the like, if obvious differences exist, such as the obvious difference of the pointer position or the obvious difference of the change amplitude (speed), the calibrated meter is indicated to have problems and needs to be further completely calibrated, and if no difference exists by visual inspection, the calibrated meter is indicated to be in a good state without using a complete calibration process for verification;

due to the design of color change, the auxiliary observation can focus the observation focus on the calibrated meter, and when the color change of the standard device is displayed as the first color (the color change is more prominent and can be observed), whether the pointer of the calibrated meter passes through the main scale mark or not is observed, if the pointer of the calibrated meter does not reach the main scale mark or passes through the main scale mark before, the problem of the calibrated meter at the corresponding main scale mark can be more accurately judged, further complete calibration is needed, and if the pointer of the calibrated meter can just pass through the main scale mark every time the color change of the standard device is displayed as the first color, the good state of the calibrated meter can be more accurately indicated.

After the fast calibration of the calibrated meter with the range of 1.6MPa is completed, the standard device is not required to be replaced, only the calibrated meter with the range of 1.6MPa is dismounted, and the calibrated meter with the range of 7MPa is accessed to the calibrated interface.

Compared with a common pointer type pressure gauge, the intelligent pressure gauge has the advantages that the intelligent pressure gauge can quickly check the pressure gauges with different measuring ranges and different accuracies within the range of range and accuracy allowance without replacing a standard gauge, and checking efficiency is high.

Another significant advantage of the pressure gauge in this example is that by designing a color change scheme, key points (main scale lines) can be observed in a focused manner on the basis of rapid verification, thereby further improving accuracy and reliability of rapid verification.
