[0001] This invention belongs to the field of simulation training technology, and in particular relates to a simulation training system and method for a simulated gas testing instrument. Background Technology

[0002] Currently, research on gas detectors mainly focuses on the gas detectors themselves, such as:

[0003] The prior art provides a portable gas detector, including a housing: the housing houses an air pump, a battery pack, a circuit board, and a sensor. An air intake port is located at the front center of the housing. The inner end of the air intake port is connected to the air pump via an air tube. The outer end of the air intake port is a cylindrical externally threaded connection section. A filter is installed inside the externally threaded connection section. The filter is positioned within the air intake port and is limited by a nut engaging with the externally threaded connection section. A connecting pipe is located at the upper end of the filter and connects to a gas sampling tube. As an improvement, the filter is a cylindrical structure that mates with the inner cavity of the externally threaded connection section of the air intake port. Multiple filter holes are formed at the bottom of the filter. The inner end of the air intake port is a reduced-diameter connector. One end of the air tube inside the housing is connected to the connector, and the other end is connected to the air pump. The upper end of the nut has an opening for the gas sampling tube to pass through. A retaining ring is circumferentially positioned at the upper middle part of the filter. The diameter of the opening at the upper end of the nut is smaller than the diameter of the retaining ring. The nut is threaded onto the air intake port of the housing, limiting the filter's position. The front end of the housing, located on one side of the air intake, features an LED light that functions as a flashlight. The LED light is electrically connected to the circuit board. The housing is a flat cylindrical structure, wider at the front and narrower at the rear, formed by fitting an upper housing and a lower housing together. The air intake is located at the front of the lower housing. The lower housing contains three cavities (front and rear) for housing the battery pack, air pump, and sensor. An air supply tube groove is formed between the battery pack cavity and the air pump. Furthermore, the sensor uses a four-in-one module. After fitting the upper and lower housings together, a mounting port for the LED light is formed at the front. The circuit board is located inside the upper housing, and the LED light is electrically connected to the circuit board. Further, the circuit board is flush against the inner wall of the upper housing. The front and middle sections of the upper housing have cutouts for the display screen and switch buttons, which are connected to the circuit board. Further, an indicator light is mounted at the front of the circuit board; correspondingly, the front of the upper housing has a circular hole for the indicator light. Finally, a buzzer is located inside the housing, and a sound-transmitting hole is provided on the upper housing. Finally, the side of the casing also features a warning light and a Type-C port.

[0004] The aforementioned portable gas analyzer features a filter inside the intake port at the front of its housing. The filter is secured by a nut, preventing it from falling off the sampling tube during gas collection and ensuring safe and reliable operation. The sensor uses a four-in-one module, which can be replaced after the trial period. An LED light is located at the front of the housing, giving the analyzer a flashlight function. An alarm light and buzzer are also included; the instrument automatically sounds an alarm when harmful gases are detected. This portable gas analyzer has a simple and reasonable structure, is safe and convenient to operate, and is compact in size, making it easy to carry. It can also be used as a flashlight and meets the testing requirements at depths of tens of meters in ship engine rooms.

[0005] The prior art also provides a handheld combustible gas detector with a protective structure, including a shell, a support foot, and a buffer spring. A rotating column is connected to the outer side of the shell, and a cover plate is connected to the right side of the rotating column. A first connecting block is fixed to the right side of the cover plate, and a locking rod passes through the interior of the first connecting block. A second connecting block is fixed to the bottom of the shell, and a ball bearing is installed inside the second connecting block. One end of the ball bearing is connected to the rotating block, and a hook is connected to the bottom of the rotating block. The support foot is located on one side of the shell, and a rubber pad is connected to one end of the support foot. A fixing groove is formed at the bottom of the rubber pad, and a movable block is installed inside the fixing groove. An adsorption block is connected to one end of the movable block. The buffer spring is located on the inner side of the shell, and a tester is fixed to one end of the buffer spring. A silicone pad is connected to the bottom of the tester. The cover plate forms a rotating structure with the shell through the rotating column, and the cover plate is nested outside the locking rod. The locking rod and the first connecting block form a magnetic structure. The hook forms a rotating structure with the second connecting block through the rotating block, and the ball bearings are evenly distributed at equal angles about the center of the rotating block. The support feet are bonded to the rubber pads, and four support feet are symmetrically arranged about the center line of the outer shell. The rubber pads have a regular pentagonal cross-section. The adsorption block forms a sliding structure with a movable block and a fixed groove, and the adsorption block is arranged in a ring shape when viewed from above. The tester is nested inside the outer shell, with the bottom of the tester and the top of the silicone pad fitting together. The buffer springs are evenly distributed around the outer wall of the tester.

[0006] The aforementioned handheld combustible gas tester is equipped with a cover plate and a locking rod. Pushing the cover plate causes the rotating column to rotate on the outer shell, connecting the cover plate to the first connecting block. The locking rod then secures the cover plate and the first connecting block. The top of the locking rod adheres to the first connecting block, preventing the locking rod from falling off. The cover plate also protects against dust, thus providing a dust-proof effect for the device. A hook is provided. Rotating the hook causes the rotating block to rotate within the second connecting block. Ball bearings are distributed between the rotating block and the second connecting block, making the rotation of the rotating block smoother. The inner wall of the hook is frosted, allowing the device to be hung on the user's body, making it convenient to carry and remove. A buffer spring and a silicone pad are also provided. The buffer spring is evenly and symmetrically distributed around the outer wall of the tester, and the bottom and top of the tester are connected to the silicone pad, thus providing good protection for the device.

[0007] In developing this invention, the inventors discovered that existing technologies rarely focus on simulation training for gas detectors. However, with the increasing prevalence of computer-based education and the growing maturity of computer technology and software, simulation training systems for educational purposes will see wider application in the future. Although more and more virtual simulation systems are being deployed, there is still a lack of simulation training systems capable of simulating real gas detection scenarios to guide students and staff in correctly operating gas detectors, understanding the characteristics and hazards of different gases, and taking appropriate countermeasures for different gas leak conditions.

[0044] Example 1

[0045] Figure 1 This is a schematic diagram of the overall structure of a simulation training system for a simulated gas testing instrument according to an embodiment of this application. Figure 2 This is a schematic diagram of the specific structure of the test instrument body of the simulation training system for a simulated gas tester according to an embodiment of this application. The following is in conjunction with... Figure 1 and Figure 2 The structure of the simulation training system described in this invention will be explained in detail.

[0046] In this embodiment, the simulation training system for the simulated gas testing instrument includes at least: a testing instrument body 10 and an industrial control host 20. First, the testing instrument body 10 acquires gas state information under the simulated gas testing environment and transmits this information to the industrial control host 20. Then, based on the gas state information transmitted by the testing instrument body 10, the industrial control host 20 extracts control information adapted to the gas state information under the current simulated gas testing environment from a preset set of control information combinations that match different gas state information, and sends the extracted control information to the testing instrument body 10. Finally, the testing instrument body 10 executes the test data output action according to the test data output method indicated by the control information sent by the industrial control host 20.

[0047] The test instrument body 10 is used to acquire gas state information under the simulated gas test environment, transmit the gas state information to the industrial control host 20, and execute test data output actions according to the test data output method indicated by the control information. Based on the actual training simulation requirements, the test instrument body 10 selects an information acquisition method suitable for the current simulated gas test conditions, acquires the gas state information under the current simulated test environment, and transmits the acquired gas state information to the industrial control host 20. The industrial control host 20 then generates the test data output method indicated by the control information based on the gas state information under the current simulated gas test environment and outputs the corresponding test data.

[0048] Next, the tester body 10 includes: a CUID radio frequency identification unit 5 and a microcontroller. The CUID radio frequency identification unit 5 is used to identify the tag information carrying gas status information on the CUID card; the microcontroller is used to perform data interception processing on the identified tag information in the data storage area, and send the completed tag information to the industrial control host 20 for extraction of control information.

[0049] In this embodiment, the information acquisition method applicable to the current simulated gas testing conditions is either the identification of the tag information carrying gas state information on the relevant CUID card by the testing instrument body 10, or the direct reading of the preset gas state information by the testing instrument body 10. (Refer to...) Figure 2 In one specific embodiment of this application, after the tester body 10 is started, the running indicator 4 among the indicator lights 4 arranged in an array on the front face of the tester body 10 is lit. At this time, the display screen 2 on the front face of the tester body 10 displays a preset initial reading (the zero point value or reference value under environmental background, i.e., the reference reading displayed by the instrument when no gas to be tested is present). Pressing the detection button 3 arranged in an array on the front face of the tester body 10 activates the CUID radio frequency identification unit 5 on the top surface, and the identification indicator light 4 lights up to indicate that the CUID radio frequency identification unit 5 has not entered the identification state. At this time, when the tag information on the CUID card is brought close to the CUID radio frequency identification unit 5, the identification indicator light 4 goes out to indicate that the CUID radio frequency identification unit 5 has entered the identification state. Thus, the gas state information under the simulated gas test environment is obtained by identifying the tag information. Finally, the test instrument 10 transmits the acquired gas state information to the industrial control host 20, which generates control information. Based on the control information generated by the industrial control host 20, the display screen 2 is adjusted to match the gas state information in the current simulated gas test environment, and the test data is output on this basis.

[0050] Next, in a specific embodiment of this application, the microcontroller of the tester body 10 is used to execute the test data output action on the one hand, and on the other hand, for data processing. After the detection buttons 3 arranged in an array on the front face of the tester body 10 are pressed, the microcontroller sends a signal to the industrial control host 20. After receiving the signal, the industrial control host 20 starts to continuously detect whether there is gas state information input and collects it in real time, ensuring the accuracy and comprehensiveness of the received data. After the CUID radio frequency identification unit 5 identifies the tag information on the CUID card, it transmits the tag information to the microcontroller. At this time, the microcontroller intercepts tag information in the data storage area, obtaining multiple tag serial numbers representing the gas state information carried on the CUID card (i.e., each tag serial number is a code corresponding to the corresponding type of gas state information and the corresponding tester operating information) as the tag information for completing data interception. Then, the multiple tag serial numbers are transmitted via the UART serial port to the WIFI module connected to the router, thereby forwarding the multiple tag serial numbers to the industrial control host 20 through the router. Finally, the industrial control host 20, based on the multiple tag serial numbers, extracts the control information appropriate to the currently input gas state information from the preset control information combinations matching different gas state information (described below). In a specific embodiment of this application, the microcontroller of the tester body 10 is an STMicroelectronics STM32F103C6T6, with an operating temperature range between -40℃ and 85℃.

[0051] In one specific embodiment of this application, the gas state information carried by the tag information includes, but is not limited to: gas type, gas concentration value, simulated timestamp, gas concentration safety threshold, simulated geographic coordinates of the tester, simulated battery status of the tester, simulated operating status of the tester, simulated alarm limit parameters of the tester, and simulated communication parameters of the tester.

[0052] The CUID radio frequency identification unit 5 transmits data to the microcontroller via a UART serial port. In this embodiment, after identifying the tag information on the CUID card, the CUID radio frequency identification unit 5 transmits the tag information to the microcontroller via a different UART serial port than the one used by the microcontroller and the WIFI module.

[0053] Furthermore, the industrial control host 20 is used to extract control information adapted to the gas state information in the current simulated gas test environment from a preset set of control information combinations that match different gas state information, based on the gas state information, and then send the extracted control information to the test instrument body 10. In a specific embodiment of this application, the industrial control host 20 has preset control information combinations that match the gas state information in different simulated gas test environments (used to simulate the actual test environment), set according to the actual test environment and the corresponding actual test instrument operating parameters. After receiving the gas state information sent by the test instrument body 10, the industrial control host 20 searches for gas state information consistent with the gas state information in the current simulated gas test environment from the preset control information combinations, determines the control information to be extracted, and then extracts and sends the control information to the test instrument body 10.

[0054] In one specific embodiment of this application, the industrial control host 20 is further pre-set with test position information that matches different gas state information (used to simulate the actual test environment) based on the actual test environment and corresponding actual test location. After receiving the gas state information sent by the test instrument body 10, the industrial control host 20 determines the test position information of the gas state information in the current test environment to be simulated based on the pre-set position information, and adds the determined test position information to the currently extracted control information to control the test instrument body 10 to output test data containing the test position information.

[0055] Furthermore, the simulation training system described in this invention also includes a host computer. The host computer is used to control the test instrument body 10 to directly output a combination of test data containing normal test data and / or abnormal test data based on control information output signals, and to determine whether an alarm needs to be triggered for the current test data combination. If an alarm is triggered, the host computer controls the test instrument body 10 to trigger an alarm. The test instrument body 10 is also used to generate control information output signals and send these signals to the host computer to initiate its operation. Specifically, the host computer and the industrial control host 20 are simultaneously connected to the microcontroller via a serial port. The host computer controls the test instrument body 10 to directly output a combination of test data containing normal test data and / or abnormal test data for different gas types (e.g., oxygen, hydrogen sulfide, combustible gas, hydrogen, etc.). While the control instrument body 10 outputs test data combinations, the host computer also determines whether an alarm needs to be triggered based on a single test data point or the chain reaction between different test data points in the current test data combination. If an alarm is triggered, the control instrument body 10 directly issues the alarm. For example, if the concentration of one or more gases in the current test data combination falls below a preset threshold indicating low concentration, an alarm is triggered directly. The host computer initiates the output and alarm processes for the test data combinations based on the control information output signal generated and emitted by the test instrument body 10 after the measurement key 6 on the top surface of the test instrument body 10 is pressed. This signal contains the requirements for the desired test data combination.

[0056] In this embodiment, the host computer communication uses a WIFI wireless communication module. This module integrates transparent transmission functionality, supports the serial port AT command set, and enables network access via the serial port. The signal interaction between the host computer and the test instrument body 10 is achieved based on the radio frequency transmission module in its built-in signal transmission circuit.

[0057] In this embodiment, the simulation training system also includes a card reader connected to the host computer via a local area network. The host computer also has pre-set control information combinations that match gas state information under different simulated gas testing environments (used to simulate actual testing environments), set according to the actual testing environment and corresponding actual testing instrument operating parameters. These control information combinations are consistent with those within the industrial control host 20. Furthermore, based on the CUID card number read by the card reader, the host computer extracts the control information corresponding to the gas state under the current simulated testing environment. This information serves as a redundant backup for the industrial control host 20, controlling the testing instrument 10 to output test data and trigger alarms, ensuring the continuity of the simulation training system's operation.

[0058] The microcontroller is also used to receive and parse control information to extract information about screen control, thereby outputting the gas state information under the current simulated gas test environment in a numerical display format. In this embodiment, the microcontroller receives and parses control information from the industrial control host 20, extracts information for controlling the display screen 2 (information about screen control) from the parsed control information, and then controls the display screen 2 to display the numbers based on the serial port, thereby achieving the purpose of outputting the gas state information under the current simulated gas test environment in a numerical display format.

[0059] Furthermore, the microcontroller is also used to determine whether there is alarm-related control information in the parsed control information, and when it is determined to be present, it controls the buzzer to sound an alarm by pulling the pin level high. Specifically, in addition to extracting information for controlling the display screen 2 (i.e., information about screen control) from the parsed control information, the microcontroller also identifies whether there is alarm-related control information in the unextracted information, that is, confirms whether the industrial control host 20 or the host computer has sent alarm-related control information. In this way, when it is determined to be present, the microcontroller pulls the pin level high to control the built-in buzzer (located inside the tester body shell 1) of the tester body 10 to sound an alarm.

[0060] Reference Figure 2 The tester body 10 has a built-in circuit board. The circuit board contains the aforementioned microcontroller, boost circuit, voltage regulator circuit, charging circuit, WIFI communication circuit and WIFI module.

[0061] Furthermore, the tester body 10 of the present invention also includes a screen control unit. The screen control unit is used to control the screen to turn off when the screen display duration reaches a preset duration threshold. Specifically, in this embodiment, the screen control unit starts timing each time the screen display begins, and when the screen display duration obtained from each timing reaches the preset duration threshold, the screen control unit controls the display screen 2 to turn off, thereby improving the battery life of the tester body 10.

[0062] Furthermore, the microcontroller is also used to obtain the analog battery voltage of the tester body 10 through a designated pin, and convert the analog battery voltage into a digital value to obtain the remaining power of the tester body 10; the industrial control host 20 is also used to receive the remaining power and output it. In this embodiment, the industrial control host 20 is also used to query the remaining power of the tester body 10. When it is necessary to query the remaining power, the industrial control host 20 generates and sends a query remaining power control command to the microcontroller. The microcontroller responds to the query remaining power control command, detects the analog battery voltage through a designated pin, and converts the analog voltage into a digital value based on its built-in AD digital-to-analog conversion function. After calculation, it generates the remaining power data and sends the remaining power data to the industrial control host 20. The industrial control host 20 receives the remaining power data and outputs it to the corresponding external device for power display as needed.

[0063] Furthermore, the industrial control host 20 is also used to correct the tag information currently identified by the CUID radio frequency identification unit 5 by transmitting the latest alarm limit parameters adapted to different gas state information under actual gas testing environment to the test instrument body 10. Specifically, in this embodiment, the industrial control host 20 also (based on remote data transmission and other means) acquires the latest alarm limit parameters corresponding to different gas types when an alarm is triggered under actual working conditions in real time, and sends the latest alarm limit parameters acquired in real time to the test instrument body 10 to replace the alarm limit parameters in the tag information currently identified by the CUID radio frequency identification unit 5, thereby correcting the tag information identified by the CUID radio frequency identification unit 5, so that the simulation results are highly consistent with the actual gas test results. In addition, while acquiring the latest alarm limit parameters in real time, the industrial control host 20 also acquires the safety setting status adapted to the latest alarm limit parameters in real time, thereby completing the simulation training of selecting appropriate response measures for different gas leakage conditions.

[0064] Furthermore, the main body of the tester includes a charging current regulation unit. This unit reduces the charging current when the battery's charging voltage reaches a preset voltage threshold, thereby extending the battery's lifespan. In this embodiment, a combination of an LTC4054ES5-4.2 boost control chip, a single-cell lithium-ion battery charger, and a constant 5V boost controller is used as the charging current regulation unit. The main body of the tester has a built-in voltage detection device that monitors the charging voltage in real time during charging and determines whether the preset voltage threshold has been reached. When the real-time charging voltage reaches the preset voltage threshold (e.g., 4.2V), the charging current regulation unit activates to reduce the charging current, thereby extending the battery's lifespan.

[0065] In one specific embodiment of this application, the simulation training system of the present invention uses an 18650 lithium battery with a nominal capacity of 1800mAh and a nominal voltage of 3.7V to 4.2V. Since the voltage of the microcontroller pin is 3.3V and the nominal voltage is 3.7V to 4.2V, a voltage divider acquisition method is used to detect the charging voltage.

[0066] In this embodiment, the industrial control host 20 also stores the received tag information carrying gas state information, which facilitates the management and tracking of tag information.

[0067] In one specific embodiment of this application, the microcontroller is also configured with a debug port. The debug port is used to initialize the pins on the microcontroller that participate in the execution of simulation training actions.

[0068] Example 2

[0069] On the other hand, based on the simulation training system for simulating a gas tester described in Embodiment 1 above, this embodiment of the invention also proposes a simulation training method for simulating a gas tester (hereinafter referred to as the "simulation training method"). This simulation training method utilizes the aforementioned simulation training system for simulating a gas tester to effectively simulate the gas tester.

[0070] Figure 3 This diagram illustrates the steps of a simulation training method for a simulated gas testing instrument according to an embodiment of this application. Figure 3 As shown, the simulation training method of the present invention includes the following steps: Step S310: The test instrument body acquires the gas state information under the simulated gas test environment and transmits the gas state information to the industrial control host; Step S320: According to the gas state information in Step S310, the industrial control host extracts control information that is compatible with the gas state information under the current simulated gas test environment from a preset control information combination that matches different gas state information, and sends the extracted control information to the test instrument body; Step S330: The test instrument body executes the test data output action according to the test data output method indicated by the control information in Step S320.

[0071] This invention proposes a simulation training system and method for simulating gas testing instruments. The testing instrument itself acquires gas state information under the current simulated testing environment, while the industrial control host analyzes this information and controls the instrument based on the analysis results, thereby outputting gas test results that match the acquired gas state information. This invention enables simulation testing of different gas conditions in any setting, overcoming the deficiency in existing technologies that lack facilities for simulating real gas detection scenarios for education and training. It provides convenience for learning the correct operation of gas testing instruments, understanding the characteristics and hazards of different gases, and taking countermeasures against abnormal gases.
