Description

Technical Field

[0001] The present invention relates to the technical field of safety protection, and in particular to a Mesh online protection air tightness inspection device. Background Art

[0002] In high-risk industries such as military and chemical industries, the air tightness of protective equipment is directly related to the life safety of personnel. Traditional air tightness testing methods often rely on manual operations, which are not only inefficient but also difficult to ensure the accuracy of the test results. With the development of science and technology, some modern air tightness testing equipment has gradually been applied to these fields, but most of these devices have the following problems:

[0003] (1) Insufficient detection accuracy: The sensors used in some equipment are not accurate enough to accurately reflect the actual gas concentration inside the protective equipment, thus affecting the reliability of the detection results. (2) Unstable communication: Some equipment has unstable communication during data transmission, resulting in data loss or delay, affecting the real-time and accuracy of the detection. (3) Complex operation: The operating interface of some equipment is complex, making it difficult for users to quickly get started, and lacks intuitive data display and alarm functions, reducing the ease of use and practicality of the equipment. (4) Lack of intelligence: Most of the existing air tightness detection equipment lacks intelligent functions, such as automatic calibration, data analysis and remote monitoring, and it is difficult to meet the diverse needs of modern safety protection. Summary of the invention

[0004] The present invention aims to solve the following problems: (1) improve detection accuracy to ensure accurate measurement of gas concentration inside protective equipment; (2) enhance communication stability to achieve real-time transmission and reception of data; (3) simplify the operation interface to improve the usability and practicality of the equipment; (4) introduce intelligent functions such as automatic calibration, data analysis and remote monitoring.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a Mesh online protective airtightness inspection device, including hardware and software, the hardware includes protective equipment, alcohol-sensitive online sensors, Bluetooth modules, flat-panel displays, airtight tents, and alcohol concentration regulators. The protective equipment uses the FNF003A anti-gas suits, FNM009A gas masks, FNS006 anti-gas gloves, and FNX005A anti-gas boots currently distributed by the troops; the alcohol-sensitive online sensor uses a high-precision alcohol sensor and is connected to the Bluetooth module through an interface to ensure the accuracy of gas monitoring; when selecting the Bluetooth module, 10 groups that meet the Bluetooth Mesh standard are selected to ensure stable communication and data exchange with the tablet, and each Bluetooth module has an interface and can be connected to an external air sensor; the flat-panel display selects a high-precision alcohol sensor. The touch panel is a central broadcast host with strong processing power and good user interface. It supports Bluetooth Mesh communication protocol. There are multiple inflatable bottom columns at the bottom of the airtight tent, and matching inflatable columns are arranged on the inflatable bottom columns. The inflatable bottom columns and the inflatable columns together form the tent frame. Tent cloth is laid between the tent frames. The tent cloth is provided with multiple openable regional doors and matching observation windows. The interior of the airtight tent is divided into multiple detection areas according to needs. The alcohol concentration regulator uses an ultrasonic humidifier as an auxiliary device and is placed in the airtight tent. For the battlefield scene where the concentration of mustard gas of 0.2mg / m3 can cause poisoning, and the concentration of sarin of 0.5-2mg / ㎡ can cause poisoning, the alcohol concentration in the humidifier is adjusted to match the corresponding value, and water mist is generated by high-frequency vibration of 1.7MHz.

[0006] The software includes a communication and data exchange unit and a user interface. The communication and data exchange unit is connected to the Bluetooth module, is responsible for communication and data exchange, and displays the test results through the user interface;

[0007] When the Mesh online protective airtightness inspection equipment is working, first turn on the power of the tablet and the alcohol gas sensor, initialize the equipment and connect the paired Bluetooth connection. The alcohol sensitive online sensor transmits the collected data to the flat panel display, and then processes and analyzes the data. When the data is higher than the set detection concentration, an alarm voice and an alarm light prompt will be issued. When the data is lower than the normal value, there will be no alarm and a green light will be displayed.

[0008] Furthermore, the alcohol-sensitive online sensor uses high-precision oxygen and carbon dioxide sensors with a round button shape and a size of 1-3 cm. It is built into the protective equipment when in use and connected to the Bluetooth module through an interface to ensure the accuracy of environmental monitoring. The specific model is SGP30.

[0009] Furthermore, the Bluetooth module adopts the CH582M Bluetooth chip, which integrates a 32-bit RISC microcontroller with BLE wireless communication. It integrates a 2Mbps low-power Bluetooth BLE communication module, 2 full-speed USB host and device controllers and transceivers, 2 SPIs, 4 serial ports, ADC, touch button detection module, RTC and other rich peripheral resources.

[0010] Furthermore, the product features of the Bluetooth module include: (1) 32-bit RISC processor Qingke V4A; (2) Support RV32IMAC instruction set, support hardware multiplication and division; (3) 32KB SRAM, 512KB Flash, support ICP, ISP and IAP, support OTA wireless upgrade; (4) built-in 2.4GHz RF transceiver, baseband and link control, support BLE5.3; (5) support 2Mbps, 1Mbps, 500Kbps, 125Kbps; (6) receiving sensitivity -98dBm, programmable +6dBm transmission power; (7) provide protocol stack and application layer API; (8) built-in temperature sensor; (9) built-in RTC, support timing and triggering modes; (10) provide 2 sets of USB2.0 full-speed Host / Device; (11) provide 14-channel touch buttons; (12) provide 14-channel 12-bit ADC; (13) provide 4 sets of UART, 2 sets of SPI, 12 PWM, 1 IIC; (14) 40 GPIO, 4 of which support 5V signal input; (15) minimum support 1.7V power supply voltage; (16) built-in AES-128 encryption and decryption unit, chip unique ID; (17) package: QFN48.

[0011] Furthermore, the airtight tent uses the CJZ-2 nuclear airtight tent, and the air chamber of the tent is inflated with compressed air. The inner layer of the tent is divided into two areas, of which the inner layer of area 2 is completely closed and can accommodate 10 people for airtightness inspection. Each area is equipped with a 530mm*430mm transparent observation window to facilitate observation of indoor personnel activities.

[0012] Furthermore, the main body of the alcohol concentration regulator is a humidifier. When the humidifier is working, a metal oscillator will vibrate at an ultrasonic frequency, causing nearby water molecules to resonate and throw them into the air, forming volatile water mist, simulating the real scene of poison contamination.

[0013] Furthermore, the software uses an Android APP as the main way for users to interact with the alcohol concentration collection system. The Android APP provides a clear and intuitive interactive interface, allowing users to easily monitor alcohol concentration data and perform corresponding operations. The functions of the Android APP include:

[0014] (1) Real-time monitoring: Users can monitor alcohol concentration data in real time through the APP and understand the current alcohol content at any time;

[0015] (2) Data display: Clear interface design can intuitively display alcohol concentration data in the form of charts and numbers, allowing users to quickly and accurately obtain information;

[0016] (3) Threshold setting: Users can set the threshold of alcohol concentration in the APP. Once the system detects that the threshold is exceeded, it will automatically prompt or alarm to remind the user to pay attention to the change of alcohol concentration;

[0017] (4) Prompt function: Through a clear interactive interface, the system can provide users with relevant prompt information, including warning information when the alcohol content is high and reminders when drinking too much, to help users maintain safety awareness;

[0018] (5) User operations: Users can perform some operations through the APP, such as setting thresholds, viewing historical data, and sharing data with other users, so as to more conveniently manage and use alcohol concentration data.

[0019] Compared with the prior art, the advantages of the present invention are: (1) Real-time alcohol monitoring: The online alcohol detection system adopts a high-sensitivity alcohol sensor, which can detect the alcohol content in real time; (2) Data recording and analysis: The online alcohol detection system has data recording and analysis functions, and can timely analyze the alcohol concentration data to obtain detection results with good airtightness guarantee; (3) User-friendly design: The APP system interface is friendly and intuitive, allowing users to easily browse and use system functions.
