Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically a fixed gas detection device with near-field communication function. Background Technology

[0002] In modern industrial production, gas detection equipment is a crucial tool for ensuring workplace safety. These devices are typically used to monitor the concentration of harmful gases in the workplace, such as flammable gases, toxic gases, and oxygen levels, to ensure worker safety. With technological advancements, gas detection equipment has evolved from simple alarms to complex systems integrating multiple sensors and intelligent processing technologies.

[0003] However, existing gas detection equipment has some limitations in terms of use and maintenance. For example, in environments sensitive to electromagnetic interference or with high safety requirements, such as semiconductor wafer fabs and panel factories, traditional gas detection equipment needs to be disassembled and moved to a specific maintenance area for setup and adjustment. This not only increases the difficulty of maintenance but also affects the equipment's real-time monitoring capabilities. Furthermore, due to the high safety requirements of these special environments, carrying potentially interfering electronic devices, such as mobile phones and computers, is not permitted, further limiting the possibility of remote monitoring and maintenance.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a fixed gas detection device with near-field communication function. Utility Model Content

[0005] The purpose of this invention is to provide a fixed gas detection device with near-field communication function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for a fixed gas detection device with near-field communication (NFC) functionality includes a detection housing. Inside the housing is a power board with a data interface. Inside the housing is a sensor module with an inlet and outlet. Both the inlet / outlet and the data interface are located at the bottom of the housing. An outlet power supply is located adjacent to the inlet / outlet. Inside the housing is a vacuum pump. At the top of the housing is an NFC module with an identification coil. An NFC identification area is located on the top surface of the housing. The front of the housing has a panel with a window at the bottom, buttons above the window, a display screen above the buttons, and indicator lights above the display screen.

[0008] As a preferred technical solution, the data interface is an RJ45 data interface or an RS485 data interface.

[0009] As a preferred technical solution, a frame is provided inside the detection housing. The frame is used to reinforce the detection housing, and the power board, sensor module, power inlet, air pump and NFC module are all mounted on the frame.

[0010] As a preferred technical solution, the back of the testing machine housing is provided with a mounting plate, and the mounting plate is provided with multiple hook holes for easy hanging.

[0011] As a preferred technical solution, the power board is connected to the sensor module, power inlet, air pump and NFC module via wires to ensure effective communication between the components. The power board has a built-in microprocessor, and the buttons and display screen provide an interactive interface for users to operate and read the test results. The indicator lights are used to intuitively display the working status of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model is a fixed gas detection device with near-field communication (NFC) function. It achieves fast near-field communication through NFC technology. Users only need to bring an NFC-enabled device close to the instrument to complete the transmission and setting of configuration information in a short time, which significantly improves configuration efficiency and reduces time consumption and the possibility of errors.

[0014] For equipment that requires frequent configuration adjustments, such as laboratory and industrial testing instruments, NFC technology devices can quickly respond to different experimental needs or changes in the production environment, reducing downtime caused by the configuration process.

[0015] NFC communication typically employs encryption technology to ensure the security of configuration information during transmission, and its short communication distance reduces the risk of data theft. Furthermore, access control prevents unauthorized personnel from arbitrarily altering instrument parameters, enhancing the instrument's security and reliability.

[0016] Users do not need professional knowledge or complicated operating procedures. They only need to bring the NFC card close to the instrument to automatically trigger the configuration process. There is no need to perform tedious menu operations and parameter input, making the instrument configuration more intuitive and convenient and reducing the difficulty of operation.

[0017] NFC technology enables local instrument setup and software updates, avoiding the cumbersome process of disassembling and returning the instrument to the factory for upgrades. Furthermore, NFC technology facilitates interoperability between instruments, enhancing the overall system's intelligence.

[0018] By reducing the number of hardware data interfaces and cables required by traditional configuration methods, the manufacturing and maintenance costs of the instrument are lowered. At the same time, the ease of use and reliability of the instrument are improved, reducing repair costs and downtime losses caused by improper operation or configuration errors.

[0025] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution for a fixed gas detection device with near-field communication function: it includes a detection housing 1, inside which a power board 2 is installed. The power board has a data interface 201 for connecting to external devices and transmitting data. The detection housing also contains a sensor module 21, which communicates with the external environment through an inlet / outlet 211 for extracting gas samples. The inlet / outlet 211 and the data interface 201 are both located at the bottom of the detection housing for easy stable placement and connection of the device. The data interface 201 is an RJ45 data interface and an RS485 data interface.

[0027] An NFC module 27 is located on the top of the testing housing. The NFC module has an identification coil 28, and an NFC identification area 281 is formed on the top surface of the testing housing to facilitate quick communication between the user and the device via NFC technology. In addition, a panel 11 is located on the front of the testing housing. A window 29 is installed at the bottom of the panel. A button 24 and a display screen 25 are located above the panel. An indicator light 26 is located above the display screen to intuitively display the working status of the device.

[0028] The power board 2 is connected to the sensor module 21, power inlet 22, vacuum pump 23, and NFC module 27 via wires, ensuring effective communication between the components. The power board 2 has a built-in microprocessor. The sensors detect specific gas concentrations in the environment, while the buttons 24 and display screen 25 provide an interactive interface for easy operation and reading of detection results. The indicator light 26 visually displays the device's operating status.

[0029] Using NFC technology, users can quickly complete the transmission and setup of configuration information by simply bringing an NFC-enabled device close to the NFC identification area 281, significantly improving configuration efficiency and reducing time consumption and the possibility of errors. NFC communication typically employs encryption technology to ensure the security of configuration information during transmission, and its short communication distance reduces the risk of data theft. Simultaneously, access control prevents unauthorized personnel from arbitrarily changing instrument parameters, enhancing the instrument's security and reliability.

[0030] Users require no specialized knowledge or complex operating procedures; simply bringing an NFC card close to the instrument automatically triggers the configuration process. This eliminates the need for cumbersome menu operations and parameter input, making instrument configuration more intuitive and convenient, and reducing operational difficulty. NFC technology connects instrument configuration information to a cloud-based management system, enabling remote monitoring and management. Administrators can monitor instrument status in real time and make timely adjustments and maintenance. Furthermore, NFC technology facilitates interoperability between instruments, enhancing the overall system's intelligence.

[0031] By reducing the number of hardware data interfaces and cables required by traditional configuration methods, the manufacturing and maintenance costs of the instrument are lowered. At the same time, the ease of use and reliability of the instrument are improved, reducing repair costs and downtime losses caused by improper operation or configuration errors.

[0032] According to the above scheme, in this embodiment, the user starts the gas detection device by pressing button 24 on the device panel. At this time, the microprocessor on the power board 2 initializes the device and checks whether each sensor and module is working properly.

[0033] The air pump 23 starts and draws in ambient gas through the air inlet 211. The gas is then measured by the sensor module 21.

[0034] The power board 2 receives and processes the detection data from the sensor module 21. The processed data is displayed on the display screen 25. At the same time, the indicator light 26 displays different colors or flashing patterns according to the gas concentration to intuitively reflect whether the gas concentration is within the safe range.

[0035] When device configuration or data reading is required, the user can bring an NFC-enabled device (such as a smartphone or tablet) close to the NFC identification area 281. The NFC module 27 establishes a connection with the external device through the identification coil 28, enabling fast data transfer.

[0036] Using NFC technology, the device can connect to a cloud-based management system, allowing administrators to remotely monitor its status and make adjustments and maintenance as needed. Furthermore, the device can interconnect with other NFC-enabled instruments, enhancing the system's overall intelligence.

[0037] When the device needs maintenance or configuration updates, users can quickly download the latest configuration file or firmware update via NFC technology without complicated steps.

[0038] This utility model of a fixed gas detection device can not only quickly and accurately detect gas concentration, but also achieve convenient near-field communication and remote monitoring through NFC technology, greatly improving work efficiency and safety.
