[0044] Gas detectors are specialized instruments used to detect the composition and content of gases. Their core function is to convert gas molecule concentration into an electrical signal using a built-in dedicated sensor, thereby enabling gas detection. They are suitable for various occasions requiring the monitoring of specific gases. Classified by function, they mainly include temperature and humidity detectors, formaldehyde detectors, air quality detectors, alcohol detectors, and gas detectors. Gas detectors detect a wide range of gases, including common gases, industrial gases, and specialty gases, specifically air, natural gas, water gas, coke oven gas, calcium carbide gas, refinery gas, dissolved gases, and various combustible and toxic gases.

[0045] With the continuous advancement of technology, gas detectors have become an indispensable and important piece of equipment in daily life, environmental monitoring, industrial production, and other scenarios. They can effectively monitor the concentration of toxic, harmful, and flammable gases in the air and provide real-time warnings, providing reliable protection for safe operation in various fields, and their application scope is becoming increasingly wide.

[0046] However, traditional gas detectors have a single monitoring dimension, and the detection results are easily affected by environmental changes, making it difficult to guarantee the accuracy of the detection data. At the same time, their data transmission method is limited to wireless transmission, which makes them prone to data transmission interruption and loss in complex scenarios such as strong electromagnetic interference or closed environments with no signal.

[0047] In view of this, the present invention provides a gas detector and its control method. This gas detector integrates multiple sensors, which not only enriches the monitoring dimensions of the gas detector and provides a more comprehensive reference for gas data analysis and environmental assessment, but also improves the comprehensiveness and practicality of the detection. Furthermore, based on a wired data transmission method, it can improve the stability and reliability of the detection data transmission. Thus, it can not only effectively improve the accuracy and comprehensiveness of gas concentration detection through multi-parameter collaborative detection, but also rely on wired data communication to ensure the stability and anti-interference of the detection data transmission, achieving end-to-end reliable assurance from environmental data acquisition to data transmission interaction.

[0048] In this embodiment of the invention, participants Figure 1 The diagram shows a schematic of a gas detector. The gas detector includes a gas detection port, a sensor module, and a control module (i.e.,...). Figure 1 The system includes a chip control module and a USB module electrically connected to the control module. The sensor module includes an ambient light sensor, a temperature and humidity sensor, and a gas sensor. The gas detection port is connected to the gas path of the gas sensor. All three sensors—ambient light sensor, temperature and humidity sensor, and gas sensor—are electrically connected to the control module.

[0049] In this embodiment of the invention, the gas detector supports temperature, humidity and various gas detection, and has a wide range of applications, such as the gas industry, chemical industry, metallurgical industry, transportation industry, environmental protection industry and daily life.

[0050] In this exemplary embodiment, the control module refers to the main control chip, which has a variety of functions. For example, the main control chip is an X2600 chip, an X2000 chip, an X2100 chip, etc. This embodiment of the invention does not limit the specific type of chip.

[0051] In this exemplary embodiment, an ambient light sensor is used to control the operating state of the gas detector. When the detector is in use and the surrounding environment is dark, the ambient light sensor module accurately monitors the ambient light signal, which can activate the LED module. Then, based on the dimming algorithm software, the intelligent LED lighting is dynamically adjusted through the GPIO_PWM interface function inside the control module.

[0052] In this exemplary embodiment, a temperature and humidity sensor is used by the gas detector to detect real-time temperature and humidity. The control panel of the gas detector reads the values ​​collected by the sensor in real time via I2C, and then obtains the temperature and humidity of the environment in which the gas detector is located through software algorithms and signal conversion.

[0053] In this exemplary embodiment, the gas sensor is a highly sensitive, reliable, and multifunctional sensor used by gas detectors to monitor various gases, detect gas composition and content, and can monitor combustible gases, oxygen, carbon monoxide, hydrogen sulfide, etc.

[0054] In this exemplary embodiment, the USB module is used to charge the gas detector's battery interface and can also be connected to external gas detectors such as computers and televisions via a USB data cable to export test data, thereby enabling wired data communication for the gas detector. In other words, the gas detector supports USB functionality, USB charging, and connection to a computer via a data cable to transfer data.

[0055] As can be seen, the gas detector provided in this embodiment integrates multiple sensors, which not only enriches the monitoring dimensions of the gas detector and provides a more comprehensive reference for gas data analysis and environmental assessment, but also improves the comprehensiveness and practicality of the detection. Furthermore, based on wired data transmission, it enhances the stability and reliability of the detection data transmission. Thus, it not only effectively improves the accuracy and comprehensiveness of gas concentration detection through multi-parameter collaborative detection, but also relies on wired data communication to ensure the stability and anti-interference of the detection data transmission, achieving end-to-end reliable assurance from environmental data acquisition to data transmission interaction.

[0056] In one possible implementation, the gas detector further includes a communication module, which includes a WIFI_BT integrated module and a cellular communication module, and the communication module is electrically connected to the control module.

[0057] In this exemplary embodiment, the communication module is used for wireless data communication of the gas detector. The communication module includes a WIFI_BT integrated module and a cellular communication module (4G / 5G / 6G module). The WIFI_BT integrated module is... Figure 1 The WIFI+BT communication module and cellular communication module refer to Figure 1 The 4G / 5G communication module in it.

[0058] As can be seen, the gas detector supports wireless communication functions, including Wi-Fi, Bluetooth, and cellular communication. Wi-Fi is a connection method based on wireless local area network technology. The Wi-Fi communication module connects the gas detector to the Internet via wireless signals to achieve wireless data transmission. Bluetooth is a short-range wireless communication technology. The Bluetooth module can connect to a mobile phone to achieve data communication.

[0059] The gas detector provided in this invention adopts a wired + multi-wireless converged communication architecture. Combined with the adaptive switching logic of the communication link in the control module, it can automatically select the optimal communication mode according to network signal quality and data transmission requirements. This ensures the real-time and stable uploading of monitoring data and on-site video, and achieves seamless connection between on-site local debugging and remote cloud monitoring. In addition, the multi-link redundancy design greatly improves the communication stability in harsh environments, and the rich data interaction methods effectively enhance the flexibility of the gas detector, meeting the efficient communication needs of various scenarios such as industrial safety monitoring and outdoor emergency detection.

[0060] In one possible implementation, the gas detector further includes a thermal printer module electrically connected to the sensor module. The thermal printer module includes a stepper motor, a photoelectric sensor, and a thermal printhead. The stepper motor is connected to the paper drive, the photoelectric sensor is located inside the paper tray of the thermal printer module, and the stepper motor, photoelectric sensor, and thermal printhead are all electrically connected to the control module.

[0061] In other words, the stepper motor drives the paper to feed and retract, the photoelectric sensor detects in real time whether the paper is out of print, and the thermal printhead prints out the real-time monitoring data collected by the gas sensor. During operation, the thermal printhead prints the real-time data monitored by the gas sensor onto the paper, while simultaneously driving the stepper motor to feed the paper synchronously according to the printing progress to complete the printing of real-time data; when the photoelectric sensor detects a paper shortage, it transmits the paper shortage signal to the control module.

[0062] In this embodiment of the invention, by setting a photoelectric detection sensor in the paper tray and linking it with a stepper motor and a thermal head for control, the paper status can be identified in real time, preventing hardware damage caused by empty printing; at the same time, the printing process is automated, eliminating the need for manual operation and improving the convenience and reliability of the gas detector in the field.

[0065] As can be seen, the gas detector also supports camera functionality; it supports one-click photo taking and one-click video recording, acquiring data through the camera module and automatically saving and uploading the data via wireless communication. When used in the gas industry, if a gas leak is detected, photos of the surrounding environment can be taken to notify relevant technicians for repairs. When used in the transportation industry, if a driver is detected to be driving under the influence of alcohol or drugs, the video recording function can be activated to save the scene and prevent any rash actions. Similarly, in other industries, photos / videos can be taken and recorded as needed to preserve the event environment.

[0066] In one possible implementation, the gas detector further includes a fan module, which is set corresponding to the gas detection port and is electrically connected to the control module.

[0067] In this exemplary embodiment, the rotation of the fan blades can accelerate the flow of the gas to be measured into the gas detector's probe port, thereby achieving more accurate measurements. Clearly, the fan module, positioned corresponding to the gas detector probe port, actively guides the flow of the gas to be measured into the gas sensor, improving gas acquisition efficiency and detection response speed while ensuring accurate and reliable detection data. This also broadens the applicability of the gas detector in enclosed, low-flow-rate environments.

[0069] In this exemplary embodiment, the light indicator module includes a first LED and a second LED. The first LED is used to provide illumination for the gas detector, and the second LED is used to activate an abnormal safety warning light after the gas sensor detects abnormal data.

[0070] As can be seen, the gas detector can visually indicate various working and fault states of the gas detector by the on / off state of different LED lights, making the status identification intuitive and efficient; the LED lights have a simple structure and low power consumption, and can work stably in various complex environments, effectively improving the on-site usability and working condition identification of the gas detector.

[0071] In one possible implementation, the gas detector further includes a button module, which includes multiple buttons and is electrically connected to the control module.

In other words, the key module can control the power on / off of the gas detector, the illumination of the gas detector, the forward and reverse rotation of the gas detector's fan, and the printing output of the gas detector's detection data.

[0073] As can be seen, the gas detector also supports a button module with multiple buttons, each button corresponding to a different function module for independent control, realizing one-click triggering of each function, and the operation method is intuitive and simple; the independent button design can effectively reduce accidental operation, and can be operated without relying on the display screen, with strong environmental adaptability, greatly improving the field usability and operational stability of the gas detector.

[0074] In one possible implementation, the gas detector further includes a display module, which is electrically connected to the control module.

[0075] In this exemplary embodiment, the display module (LCD Module) is used to display the status information of the gas detector, such as time, battery level, detection data, etc., which is not limited in this embodiment of the invention.

[0076] As can be seen, the gas detector also supports an RTC clock and an LCD display screen, which can display detection data and time parameters. The LCD display screen provides visual feedback on the gas detector's detection data and time parameters, facilitating quick identification of the gas detector's usage status.

[0077] In one possible implementation, the gas detector further includes an audio module, which is electrically connected to the control module.

[0078] In this exemplary embodiment, the audio module is used for the audio output of the gas detector; the audio module is designed with a speaker (SPK) and a buzzer circuit, and outputs audio to an external audio power amplifier circuit through HPOUT, and controls the buzzer circuit through PWM_GPIO to realize voice playback and warning prompts.

[0079] As can be seen, the gas detector also supports AUDIO functionality, including speaker SPK and buzzer sound output, providing detection and early warning functions. In other words, the gas detector can achieve differentiated audio prompts and sound-and-light linked alarms, overcoming the limitations of visual recognition in various scenarios. It can promptly deliver early warning information in various complex working conditions, effectively improving the equipment's safety protection capabilities and ease of use on-site.

[0080] In one possible implementation, the gas detector further includes a power module, which is electrically connected to the control module.

[0081] In this exemplary embodiment, a power module is used to power the gas detector. The power module circuit design supports battery power, button power-on, and low-power sleep / standby modes, thus meeting the requirements for long-term operation.

[0082] In one possible implementation, the gas detector further includes a storage module, which is electrically connected to the control module.

[0083] In an exemplary embodiment, the storage module (SD_Card_FLASH Module) is used for system startup and data storage of the gas detector, supporting the storage of photographed and video data. It also supports FLASH functionality, enabling the storage of large-capacity data files.

[0084] In one possible implementation, the gas detector is also connected to an external monitoring system module.

[0085] It is evident that the gas detector also has the ability to connect and interact with external monitoring systems, enabling remote uploading and centralized management of monitoring data, alarm information, and on-site images. This facilitates remote control and unified operation and maintenance of multiple gas detectors. Cloud storage of data not only ensures the integrity and security of monitoring evidence but also enables remote early warning and linkage for abnormal events, effectively enhancing the value of gas detectors in large-scale and networked applications and meeting the remote safety supervision needs of multiple industries.

[0099] In this exemplary embodiment, the power module is functionally connected to the internal power supply interface and SADC interface of the control module through the battery circuit. The SADC function within the control module can monitor the battery power status, which can be displayed on the screen. If the battery power is detected to be too low, the software can announce "Low battery, please charge" through the audio module to prompt the user to charge. If the battery is detected to be fully charged, the software can also control the working status of the charging circuit through GPIO.

[0101] In one possible implementation, see Figure 3 The diagram shown is a schematic of a gas detector provided in an embodiment of the present invention.

[0102] exist Figure 3 The gas detector shows a gas detection port 1, an ambient light sensor 2, a gas detection sensor 3, a temperature and humidity sensor 4, a first LED light 5, a camera sensor module 6, a second LED light 7, an audio module including a buzzer output interface 8 and a speaker output interface 9, a thermal printer module including a thermal head output interface 10 and a thermal paper input interface 11, a display module including an LCD display screen 12, a button module including a multi-function button 13, a power module including a battery power interface 14, and a USB function interface 15 of a USB module.

[0103] As can be seen, the gas detector provided in this embodiment of the invention is small in size and easy to carry, with a long battery life. It can be powered by a battery or charged via a USB interface, greatly meeting the needs of long-term operation. Furthermore, the gas detector supports wired communication and various wireless communication schemes, enabling the transmission of detected data, such as data from mobile phones / PCs. It also supports photo and video recording functions to obtain relevant data on abnormal environmental conditions; it supports printing detection information; it supports speaker SPK sound output and buzzer sound output; it supports LED light functionality; it supports an LCD display; and it supports external monitoring systems. Clearly, the gas detector provided in this embodiment of the invention is feature-rich and meets diverse market demands.

[0104] It should be noted that, Figure 3 The diagram shown is an exemplary assembly structure of the gas detector of the present invention. This disclosure does not limit the specific assembly form or component layout of the gas detector. The gas detector may also adopt other equivalent assembly structures and layout forms according to actual application requirements.

[0105] To further illustrate the gas detector control method provided in the embodiments of the present invention, a detailed description is provided below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiments of the present invention provide method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on conventional or non-inventive methods. In steps where there is no logically necessary causal relationship, the execution order of these steps is not limited to the execution order provided in the embodiments of the present invention. In actual processing or device execution, the method may be executed in the order shown in the embodiments or drawings, or in parallel (e.g., in an application environment with parallel processors or multi-threaded processing).

[0106] The following combination Figure 4 The flowchart shown illustrates the gas detector control method in this embodiment of the invention. The method can be executed by an electronic device, and the specific implementation flow of the method is as follows: Step 401: The gas to be tested is guided to the gas sensor through the gas detection port; Step 402: Acquire monitoring data from the ambient light sensor, temperature and humidity sensor, and gas sensor, and determine the detection results based on the monitoring data; Step 403: Transmit the test results to an external device via the USB module.

[0107] In this embodiment of the invention, considering that users also have wireless transmission needs, the detection results can be transmitted to an external device via a communication module in response to a wireless transmission request. For example, the detection results can be transmitted to the external device via a Wi-Fi module, or via a Bluetooth (BT) module. Alternatively, they can be transmitted to the external device via a cellular communication module; this embodiment of the invention does not limit the specific method used. The external device can be, for example, a smartphone, tablet computer, or computer; this embodiment of the invention does not limit the specific device used.

[0108] As can be seen, the solution provided in this embodiment of the invention supports wired and multiple wireless data communication functions. Therefore, it can adapt to different network environments such as indoor LANs, outdoor wide-area cellular networks, and short-range direct connections in the field, and is not limited by fixed wiring conditions. It can meet the wired high-speed transmission needs of fixed locations such as laboratories and computer rooms, and is also suitable for mobile usage scenarios without broadband coverage, such as outdoor inspections, field monitoring, and industrial sites. Furthermore, multiple communication methods serve as backup links for each other. In this way, when a certain communication mode fails or the signal is interrupted, it can automatically switch to other available communication links to avoid interruption of monitoring data and on-site image data transmission, ensuring continuous and stable operation of the equipment. This is especially suitable for gas safety monitoring scenarios with high requirements for data real-time performance.

[0109] Furthermore, during actual implementation, the optimal transmission method can be selected as needed. For example, for short distances, Bluetooth / Wi-Fi can be used to achieve direct communication with mobile terminals such as mobile phones and tablets, facilitating on-site debugging, data reading, and parameter configuration. For medium to long distances, 4G / 5G can be used to upload data to the cloud and perform remote monitoring. Wired communication can meet the high-speed and stable transmission of large-volume video data and batch monitoring data, thus balancing data transmission efficiency and on-site ease of use.

[0110] In this embodiment of the invention, considering that users also have wireless transmission needs, the paper tray can be determined as needed in response to a printing request based on the signal from the photoelectric detection sensor. When it is determined that there is no paper shortage, the stepper motor is driven to feed the paper, and the thermal head is controlled to print out the monitoring data.

[0111] In this embodiment of the invention, a closed-loop control method of "paper shortage signal detection + logic judgment + linked execution printing" is adopted to achieve intelligent and autonomous control of the printing process. On the one hand, it can effectively avoid invalid printing actions in the case of paper shortage, protect the printing components and reduce equipment energy consumption; on the other hand, it can automatically print out immediately after the monitoring data is collected, quickly generate on-site paper records, simplify the operation process, and significantly improve the practical performance and work efficiency of gas detectors in outdoor, emergency and other scenarios.

[0112] In this embodiment of the invention, considering that users also require monitoring, photography, and video recording functions, the camera sensor module can be controlled to collect environmental data from the gas detector in response to a shooting request. Furthermore, the environmental data can be transmitted to external devices via a USB module and / or a communication module.

[0113] In this embodiment of the invention, the camera sensor module of the gas detector supports one-click photo taking and one-click video recording. That is, data can be acquired through the camera sensor module, and the data can be automatically saved and uploaded through wireless communication and / or wired communication functions.

[0114] For example, when used in the gas industry, if a gas leak is detected at a certain location, the scene can be photographed and the relevant technicians can be notified for repairs; when used in the transportation industry, if a driver is detected to be driving under the influence of alcohol or drugs, the video recording function can be activated to save the scene video in order to prevent any extreme behavior; if used in other industries, photos / videos can also be taken and recorded as needed to save the event environment.

[0115] As can be seen, gas detectors can automatically trigger photo or video recording when abnormal conditions are detected, depending on the application scenarios of different industries. This enables the visualization and evidence preservation of the on-site environment. Automatic linkage recording ensures the complete retention of event information, facilitating post-event traceability and handling. At the same time, in sensitive scenarios, it can standardize on-site behavior, avoid conflicts, and improve the safety and intelligence level of gas detector use.

[0116] In this embodiment of the invention, the fan module can also be driven to start operation, so as to accelerate the flow of the gas to be tested into the gas sensor through the gas detection port.

[0117] As can be seen, by actively guiding the airflow through the fan module, the natural passive diffusion of gas is transformed into forced active inflow, significantly shortening the time it takes for the gas to reach the gas sensor. This effectively improves the gas detection response speed of the equipment, enabling rapid detection of abnormal states such as leaks and exceeding limits. Furthermore, the continuous operation of the fan can push fresh gas to flow steadily through the sensor probe, preventing gas from stagnating or accumulating in the detection inlet or gas path. This ensures that the sensor is in real-time contact with the true concentration of the gas to be measured, effectively improving the accuracy and reliability of the detection data.

[0118] Thus, for detection scenarios involving confined spaces, poor air circulation, and weak natural convection, active air intake can solve the problem of low gas diffusion efficiency, enabling the equipment to collect gas normally even under harsh operating conditions and complex environments, significantly improving the scenario adaptability of the gas detector. Furthermore, forced airflow ensures real-time updates of gas concentration on the sensor surface, eliminating detection lag and achieving continuous and stable online monitoring, which is particularly suitable for safety monitoring scenarios requiring real-time early warning, such as gas leaks and excessive levels of harmful gases. In other words, the gas detector and its control method provided in this embodiment of the invention can adapt to various complex operating conditions, enhance the equipment's ability to continuously and stably monitor, and improve the timeliness and reliability of safety early warnings.

[0119] In this embodiment of the invention, the working status information of the gas detector can also be obtained; wherein, the working status information includes lighting requirement information and / or warning information; and then, according to the working status information, the light indicator module, including at least two LEDs, is controlled to perform corresponding on / off actions.

[0120] For example, when the working status information includes lighting requirement information, the indicator light module can be controlled to illuminate the first LED; when the working status information includes warning information, the indicator light module can be controlled to illuminate the second LED; when the working status information includes both lighting requirement information and warning information, the indicator light module can be controlled to illuminate both the first and second LEDs.

[0121] In this embodiment of the invention, the on / off state of the gas detector can be indicated by the combination of at least two LEDs, representing various operating states such as normal monitoring, gas exceeding the standard alarm, paper shortage fault, data upload, and communication abnormality. This allows for remote and intuitive identification of the equipment's operating status without relying on a display screen, resulting in high on-site visibility. Furthermore, for dangerous or abnormal scenarios such as gas leaks, drunk driving detection, and sensor malfunctions, dedicated indicator lights can provide immediate warnings, enabling staff to identify potential hazards and take appropriate measures immediately, significantly improving the timeliness of safety monitoring and emergency response.

[0122] As can be seen, in this embodiment of the invention, different LED lights are automatically driven to indicate the operating status of the gas detector, which can realize automated and visual feedback of information such as normal operation, abnormal alarm, and fault indication. The device status can be presented in real time without manual intervention, which is convenient for quickly identifying safety hazards and has the advantages of low power consumption and high reliability, thus improving the intelligence level and field applicability of the gas detector.

[0123] In this embodiment of the invention, control information of the gas detector can be obtained; wherein, the control information includes at least one of switch control sub-information, light control sub-information, fan control sub-information and printing control sub-information, and then, according to the control information, the control button module includes multiple buttons to execute corresponding control actions.

[0124] For example, it can receive user input on the first button sub-module of the button module used to control the power on / off of the gas detector, thereby generating switch control sub-information, and then controlling the power on and off of the gas detector according to the switch control sub-information.

[0125] For example, it can receive user input on the second button sub-module of the button module for controlling the light on the gas detector, thereby generating light control sub-information, and then controlling the light on and off of the gas detector according to the light control sub-information.

[0126] For example, it can receive user input on the third button submodule of the button module for controlling the forward and reverse rotation of the gas detector's fan, thereby generating fan control sub-information, and then controlling the forward and reverse rotation of the gas detector's fan according to the fan control sub-information.

[0127] For example, it can receive user input on the fourth button submodule of the button module for controlling the printing output of gas detector detection data, thereby generating printing control sub-information, and then controlling the gas detector to print or stop printing based on the printing control sub-information.

[0128] In this embodiment of the invention, the user can operate based on preset button operation commands to control various functions, such as pressing twice to turn on, pressing three times to turn off, etc. This embodiment of the invention does not limit this.

[0129] In this embodiment of the invention, by inputting different control commands through multiple independent buttons, the control module can accurately drive the corresponding module to perform actions according to the button signals, thereby achieving personalized and fast function control. This simplifies the on-site operation process, reduces the probability of misoperation, and can quickly respond to work needs such as fan rotation and printing, thereby improving the operation efficiency and intelligence level of the equipment in monitoring scenarios in multiple industries.

[0130] In this embodiment of the invention, the usage status information of the gas detector can be obtained; wherein, the usage status information includes at least one of power usage information, time information, and detection result information; then, the control display module displays the usage status information.

[0131] As can be seen, the usage status information of the gas detector can be visualized, making it easy to quickly identify the usage status of the gas detector.

[0132] In this embodiment of the invention, the audio output information of the gas detector can be acquired, and then the audio module can be controlled to output audio information. This enables differentiated audio prompts and sound-and-light linked alarms, overcoming the limitations of visual recognition in various scenarios, and timely delivering early warning information under various complex working conditions, effectively improving the equipment's safety protection capabilities and ease of use on-site.

[0133] The control scheme for the gas detector provided in this invention not only supports data transmission control for wired communication and various wireless communication methods, but also supports control of various functions, such as photo taking and video recording; printing of detection information; control of warning sounds (including speaker SPK and buzzer output); control of LED lights; control of LCD display screens; and inter-system linkage control with external monitoring systems. Clearly, the control scheme for the gas detector provided in this invention offers a wide range of functions, meeting diverse market demands.
