[0025] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0030] The temperature and pressure simulation monitoring of the gas pipeline collection point is conducive to the research on the performance of the gas collection terminal. However, the inventors found that even if the existing gas simulation device sets the temperature and pressure simulation knobs corresponding to the gas input and output directions to simulate the gas environment at the collection point, manual adjustment is required to change the temperature and pressure of the gas environment simulation. The temperature and pressure data that rely on manual adjustment are not only subjective, but also unable to simulate the timely supervision of the gas pipeline temperature and pressure. If there are many simulated collection points, each simulated collection point needs to be adjusted separately, which is cumbersome to operate and has low applicability.

[0031] Based on this, this specification embodiment proposes a processing solution: Figure 1 As shown, by setting the first switch and the second switch on the existing temperature and pressure environment simulator, when the gas needs to remain unchanged for a long time, the first switch is used to simulate the gas environment temperature and pressure according to the temperature and pressure simulation knob corresponding to each collection point. When the gas needs to be monitored in time, the second switch is used to realize automatic and efficient simulation of the temperature and pressure required for the gas environment without complicated operations.

[0032] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, the embodiment of this specification provides an improved gas pipeline temperature and pressure environment simulation device, including a temperature and pressure environment simulator 10. Specifically, the temperature and pressure environment simulator 10 is provided with a manually adjustable temperature and pressure simulation knob such as Figure 1 1, 2, 3 and 4 are shown, and the temperature and pressure environment simulator is configured with a manual adjustment program corresponding to the temperature and pressure simulation knob. For example, the manual adjustment program corresponding to the temperature and pressure simulation knobs 1 and 2 represents the simulation data in the input direction of the gas collection point, and the manual adjustment program corresponding to the temperature and pressure simulation knobs 3 and 4 represents the simulation data in the output direction of the gas collection point. That is, manually turning the temperature and pressure simulation knobs 1, 2, 3 and 4 respectively can realize the simulation data of the gas input and output at two collection points of the gas pipeline environment through the controller 7, the output port 5 and the output port 6. That is, every two temperature and pressure simulation knobs realize the simulation data of the gas input and output at one collection point through the controller 7, the output port 5 and the output port 6. Not only that, the improved temperature and pressure environment simulation device also includes a plurality of automatic adjustment programs. Compared with the manual adjustment program, the automatic adjustment program can realize the simulation data of the input and output direction of the gas pipeline at each collection point without manually turning the temperature and pressure simulation knob.

[0034] Specifically, the temperature and pressure environment simulator 10 also includes a first switch 9 and a second switch 8, wherein the first switch 9 and the second switch 8 are electrically connected to the temperature and pressure environment simulator 10, respectively. When the first switch 9 is in the first switch position (i.e., the manual gear corresponding to the triggering manual adjustment program), the temperature and pressure environment simulator is triggered to work in the manual adjustment mode to execute the manual adjustment program according to the manual adjustment of the temperature and pressure simulation knob to output the first temperature and pressure simulation data. The first temperature and pressure simulation data represents the temperature and pressure simulation data corresponding to the gas input and output directions of each collection point corresponding to the manual adjustment mode. When the first switch is in the second switch position, the temperature and pressure environment simulator 10 is triggered to work in the automatic adjustment program, and the second temperature and pressure simulation data corresponding to the initial value and the change law set by the automatic adjustment program are output. That is, the automatic adjustment program is determined by the switch selection of the second switch 8, and is no longer associated with the temperature and pressure simulation knob. The second switch can automatically supervise the gas simulation data corresponding to several collection points, and each automatic adjustment program corresponds to the gas simulation data of one collection point. Specifically, the automatic adjustment program outputs the second temperature and pressure simulation data in the gas input and output directions of each collection point according to the initial value of the gas simulation and its change law. The initial value can be set manually or automatically, and the change law has a certain natural law to output the simulation data in the gas input and output directions of each collection point compared to the subjective setting of the prior art. The gas pipeline is divided into high pressure, medium pressure, low pressure and other pipelines.

[0035] In some embodiments, the second switch includes at least one of the following switches: a dip switch and a digital switch.

[0036] Specifically, the dip switch can adopt the binary coding principle of 0 / 1. Each key of the dip switch has two pins on the upper and lower back sides. When it is turned to the ON side, the upper and lower pins are connected, otherwise they are disconnected.

[0037] The digital switch adopts the coding principle of 0-9. A digital switch with one digit can realize the setting of one of the 10 simulation data corresponding to 0-9. When collecting a large amount of simulation data such as the temperature and pressure of the gas pipeline environment, each digit of the DIP switch / data switch corresponds to an automatic adjustment program. For example, the automatic adjustment program 0 is the gas environment inlet and outlet temperature with a cycle of 30 minutes, and the range of -20℃ to 60℃ changes in a sawtooth wave; the gas environment inlet pressure data has a cycle of 40 minutes and changes in a sine wave in the range of 0 to 10KPa. No matter what kind of change pattern other automatic adjustment programs present, the temperature change range is within the range of -20℃ to 60℃, and the pressure change range is within the range of 0 to 10KPa.

[0038] In some embodiments, multiple DIP switches are connected in parallel to form multiple switch states; and / or, multiple digital switches are connected in parallel to form multiple switch states; and / or, the DIP switches and digital switches are connected in parallel to form multiple switch states.

[0039] Specifically, in some cases, the second switch is only a dip switch. When simulating the gas at multiple collection points, multiple dip switches can be connected in parallel to form multiple switch states. In some cases, the second switch is only a digital switch. When simulating the gas at multiple collection points, multiple digital switches can be connected in parallel to form multiple switch states. Alternatively, the second switch can be a dip switch and a digital switch mixed in parallel to form multiple switch states. Where each bit of the dip switch and the digital switch is set to one of the 10 automatic adjustment programs for a collection point, the switch state formed by the multiple dip switches and the digital switches in parallel can be 10 n , n is greater than or equal to 1, and n is determined by the number of dip switches and digital switches.

[0040] Therefore, when the temperature and pressure simulator corresponds to the automatic adjustment program determined by the second switch, the automatic collection data of the temperature and pressure simulation can be obtained in time without complicated manual operation, and the temperature and pressure environment simulator does not need to be changed and modified greatly, so as to realize the automatic and efficient simulation of the temperature and pressure required by the gas environment. This completely breaks through the existing technology of setting a MEMS sensor for each simulation collection point or realizing simulation by turning the knob on the simulator.

[0041] Compared with the manual adjustment simulation method in the prior art, the temperature and pressure simulation data in the embodiments of this specification has a certain change pattern.

[0042] In some embodiments, the first temperature-pressure simulation data and / or the second temperature-pressure simulation data are scattered two-dimensional data composed of temperature and pressure within the use range of the simulated MEMS sensor.

[0043] Specifically, the embodiment of this specification realizes the simulation data of temperature and pressure in the input direction and output direction of each gas collection point by setting a temperature and pressure environment simulator of an overall structure, such as first temperature and pressure simulation data output by manual adjustment and / or second temperature and pressure simulation data corresponding to the automatic adjustment program. Both of these two types of temperature and pressure simulation data can simulate the temperature and pressure data collected by setting the MEMS sensor at the collection point in the prior art, and the temperature and pressure simulation data can be output through the first output port 5 and the second output port 6 of the temperature and pressure environment simulator. For example, the scattered two-dimensional data [T1, P1] of the input direction of each gas collection point is output, or the scattered two-dimensional data [T2, P2] of the output direction of each gas collection point is output. Among them, the first temperature and pressure simulation data and / or the second temperature and pressure simulation data are manually adjusted and automatically adjusted according to the actual situation.

[0044] In some embodiments, the time interval between the values ​​of the scattered two-dimensional data and the adjacent data is a first preset interval; and / or the value difference between the scattered two-dimensional data and the adjacent data is a first preset difference value, wherein the first preset difference value represents the precision value between the two data.

[0045] Specifically, according to different simulation environments and simulation requirements of gas, the values ​​in the scattered two-dimensional data corresponding to the temperature and pressure simulation data have different requirements. For example, the time interval between the values ​​of adjacent data corresponding to the scattered two-dimensional data is the first preset interval, that is, for the scattered two-dimensional data of each gas collection point, the time interval for collecting simulation data can be set, for example, the first preset interval is set to 30 minutes, then the temperature and pressure of multiple groups of scattered two-dimensional data are collected at the first preset interval, such as two groups of adjacent scattered two-dimensional data [T1, P1] and [T2, P2], the time interval between T2 and T1 is the first preset interval t, and the time interval between P2 and P1 is also the first preset interval t.

[0046] For another example, the numerical difference between the adjacent data of the scattered two-dimensional data is the first preset difference, that is, for the scattered two-dimensional data of each gas collection point with different requirements or different environments, the collection accuracy of the simulated data collection can be set, such as setting the temperature accuracy to 0.1°, the pressure accuracy to 0.01Pa, etc. This is only an example and can be specifically limited according to the actual situation. For example, for three groups of scattered two-dimensional data [T1, P1], [T2, P2] and [T3, P3], T2-T1=m, T3-T2=n, T3-T1=l, then the first preset difference is expressed as m / m*10 h =n / n*10 h =l / l*10 h , h represents the number of digits after the decimal point. Similarly, the numerical acquisition accuracy between pressures can also be set to a corresponding first preset difference, etc., which will not be repeated here.

[0047] In some embodiments, the first temperature-pressure simulation data and / or the second temperature-pressure simulation data are three-dimensional data formed by adding a time dimension to the two-dimensional data of temperature and pressure.

[0048] As in the above embodiment, the time dimension is added to the first temperature and pressure simulation data and the second temperature and pressure simulation data of the scattered two-dimensional data to form three-dimensional data, such as two sets of scattered three-dimensional data [T1, P1, t1] and [T2, P2, t2].

[0049] In some embodiments, the temperature and pressure and the corresponding time in the three-dimensional data are data obtained by taking values ​​on a sine curve or a cosine curve that changes with time.

[0050] See also Figure 2The left and right figures are sine curves and cosine curves respectively, and the horizontal axis is time. The time corresponding to the temperature and pressure in the three-dimensional data can be a sine curve or cosine curve that changes with time, that is, in the two sets of scattered three-dimensional data [T1, P1, t1] and [T2, P2, t2], T1 and T2 follow the sine curve or cosine curve over time, and P1 and P2 follow the sine curve or cosine curve over time.

[0051] In some embodiments, the temperature and pressure and the corresponding time in the three-dimensional data are data obtained by sampling on a sawtooth wave curve that changes with time.

[0052] Figure 3 The example is a sawtooth wave curve that changes with time. The horizontal axis is time. The time corresponding to the temperature and pressure in the three-dimensional data can obtain the corresponding values ​​on the sawtooth wave curve that changes with time. That is, in the two sets of scattered three-dimensional data [T1, P1, t1] and [T2, P2, t2], T1 and T2 satisfy the sawtooth curve over time, and P1 and P2 satisfy the sawtooth curve over time.

[0053] In some embodiments, the temperature and pressure in the three-dimensional data and the corresponding time are data obtained by taking values ​​on a symmetrical triangle wave curve and an asymmetrical triangle wave curve that change with time.

[0054] See also Figure 4 The left and right figures are symmetrical triangular wave curves and asymmetrical triangular wave curves respectively, and the horizontal axis is time. The time corresponding to the temperature and pressure in the three-dimensional data can be a symmetrical triangular wave curve or an asymmetrical triangular wave curve that changes with time, that is, in the two sets of scattered three-dimensional data [T1, P1, t1] and [T2, P2, t2], T1 and T2 satisfy the symmetrical triangular wave curve or the asymmetrical triangular wave curve over time, and P1 and P2 satisfy the symmetrical triangular wave curve or the asymmetrical triangular wave curve over time.

[0055] In combination with the above embodiments, the embodiments of this specification provide an improved method for simulating the temperature and pressure environment of a gas pipeline, such as Figure 5 It includes steps S510 to S540.

[0056] Specifically, step S510: obtaining the setting state of the first switch in the improved gas pipeline temperature and pressure environment simulation device. The first switch is provided with a first switch position and a second switch position, the first switch position corresponds to the manual adjustment mode of the temperature and pressure environment simulator, and the manual adjustment corresponding to the temperature and pressure simulation knob in the manual adjustment program is executed to output the first temperature and pressure simulation data. The first switch is provided with a second switch position, the second switch position corresponds to the automatic adjustment mode of the temperature and pressure environment simulator, the automatic adjustment mode is triggered by the selection of the second switch, the automatic adjustment program is executed, and the second temperature and pressure simulation data is output according to the initial value and change rule set by the automatic adjustment program.

[0057] Step S520: triggering the temperature and pressure environment simulator to execute a corresponding program according to the setting state of the first switch.

[0058] In combination with the above embodiments, the setting state of the first switch is divided into a manual adjustment mode corresponding to the first switch position and an automatic adjustment mode corresponding to the second switch position. The automatic adjustment mode is determined by the second switch and is unrelated to the temperature and pressure simulation knob corresponding to the manual adjustment mode.

[0059] Step S530: When the first switch is in the first switch position, the temperature and pressure environment simulator is triggered to work in the manual adjustment mode to execute the manual adjustment program to output the first temperature and pressure simulation data according to the manual adjustment of the temperature and pressure simulation knob.

[0060] Specifically, when the first switch is in the first switch position, the temperature and pressure environment simulator can be triggered to work in the manual adjustment mode, that is, by manually turning the temperature and pressure simulation knob set for each gas collection point on the temperature and pressure environment simulator, the temperature and pressure simulation data of the gas input direction and output direction of the collection point are input into the processor, that is, the first temperature and pressure simulation data corresponding to the first switch being in the first switch position is determined by the manual knob on the temperature and pressure environment simulator.

[0061] Step S540: When the first switch is in the second switch position, the temperature and pressure environment simulator is triggered to work in the automatic adjustment mode, and the switch state set by the second switch is obtained. According to the switch state selected by the second switch, the temperature and pressure environment simulator is triggered to execute the corresponding automatic adjustment program, and the second temperature and pressure simulation data is output according to the corresponding initial value and change rule set by the automatic adjustment program.

[0062] When the first switch is in the second switch position, the trigger temperature and pressure environment simulator is in automatic adjustment mode. At this time, the analog output of the temperature and pressure environment simulator is determined by the second switch and is no longer associated with the manually adjusted temperature and pressure simulation knob. In some embodiments, the second switch is not limited to one switch, but can also be a plurality of switches in parallel, so the switch state of the second switch can automatically input the simulation corresponding to the plurality of acquisition points, and the automatic adjustment program for each acquisition point can be 10 kinds, etc. The automatic adjustment program outputs the second temperature and pressure simulation data according to the initial value and the change rule. Specifically, the change rule may include sine and cosine curves, sawtooth waves, symmetrical triangles and asymmetrical triangle curves, etc. The initial value can be set manually or automatically. Among the 10 automatic adjustment programs, if the automatic adjustment program 0 is the gas environment inlet and outlet temperature with a period of 30 minutes, the range of -20°C to 60°C changes in a sawtooth wave; the gas environment inlet pressure data is a sine wave with a period of 40 minutes in the range of 0 to 10KPa. No matter what kind of change pattern other automatic adjustment programs present, their temperature change range can be within the range of -20℃ to 60℃, and their pressure change range can be within the range of 0 to 10KPa.

[0063] In some embodiments, the output port includes a first output port and a second output port. Figure 1 As shown, the first output port 5 and the second output port 6 are connected through I 2 C (Inter-Integrated Circuit, a serial bus for two-way communication) is connected to the temperature and pressure environment simulator. The temperature and pressure environment simulator is provided with a first output port 5 and a second output port 6, and the first output port 5 and the second output port 6 are respectively connected to the processor 7. In some embodiments, no matter whether the first switch in the temperature and pressure environment simulation device is in the first switch position or in the second switch position, the simulated temperature and pressure simulation data are output by the first output port 5 and the second output port 6.

[0064] In some embodiments, the VDD, SCL, SDA, and GND ports of the IC bus of the temperature and pressure environment simulation device correspond one-to-one with the simulated MEMS ports, and the transmission characteristics are completely consistent. Figure 6 As shown, the first output port 5 is provided with 4 wiring harnesses, which correspond to the VDD output terminal, SCL1 output terminal, SDA1 output terminal and GND output terminal respectively. The second output port 6 is also provided with 4 wiring harnesses, which correspond to the VDD output terminal, SCL2 output terminal, SDA2 output terminal and GND output terminal respectively. The first output port and the second output port correspond to the PINs of the VDD output terminal, SCL output terminal, SDA output terminal and GND output terminal respectively, and the above PINs correspond to the PINs of the simulated MEMS port one by one, and the transmission characteristics are completely consistent. The simulated temperature signal and pressure signal can be output through the above output port, and the port setting PIN transmission characteristics are completely consistent with the PIN of the sensor port in the prior art, thereby realizing the output of simulated temperature and pressure data. The first switch and the second switch are used to realize the flexible supervision of the temperature and pressure simulation output of the gas environment, without major changes and modifications to the temperature and pressure environment simulation device, and without cumbersome operations, so as to realize the flexible and efficient output of the temperature and pressure required for the gas environment simulation.

[0065] In some embodiments, Figure 7 As shown, the first switch 9 and the second switch 8 are installed on the front panel of the temperature and pressure environment simulator. The temperature and pressure environment simulator includes an LCD display screen for displaying simulated temperature and pressure data, so as to facilitate the acquisition of simulated temperature and pressure data.

In particular, for the product embodiment described later, since it corresponds to the method, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
