[0023] See also Figure 1-Figure 4 , Figure 1-Figure 4 The figure schematically shows a device for measuring the alcohol gas concentration in a moving vehicle space by using laser according to the present invention.

[0024] In an embodiment of the utility model, a device for measuring the alcohol gas concentration in the space of a mobile vehicle using laser includes a main shell, which is characterized in that a module assembly is arranged inside the main shell, and the module assembly includes a speed measurement module 1, an infrared imaging module 2 and a laser alcohol detection module 3. A main board 5 and a wireless module 8 are also installed below the module assembly. The module assembly obtains a signal through laser detection analysis and processes and calculates the result through the main board 5.

[0025] Among them, the speed measurement module 1 adopts a radar speed meter. By utilizing the speed measurement module 1, the displacement distance relationship is captured and the vehicle's moving speed is calculated. According to the vehicle's moving speed, the position relationship of the vehicle at the next moment is calculated, and the forward position of the vehicle at the next moment is locked, so as to prepare for detecting the alcohol gas concentration inside the vehicle.

[0026] Among them, the infrared imaging module 2 uses thermal imaging technology, which can quickly perform thermal imaging of vehicles and personnel, quickly lock and locate the driver's position, and the height of the driver relative to the ground when driving different types of vehicles. Among them, according to the different heights of the driver from the ground, the angle of the laser detection alcohol module during measurement can be quickly adjusted to accurately align with the position of the cockpit for measurement.

[0027] Among them, the laser detection alcohol module 3 adopts laser measurement technology, such as TDLAS laser detection technology. The laser detection alcohol module uses the wavelength tuning of the semiconductor laser and the selective absorption of the measured gas to measure the concentration of the gas. The greater the attenuation of the light, the higher the concentration of the gas.

[0028] In the utility model, the speed measurement module 1 in the module assembly first locks the next position of the vehicle, quickly locks the height of the driver from the ground through the infrared imaging module 2, and timely adjusts the measurement angle of the laser alcohol detection module 3, and detects the alcohol gas concentration of the driver in the cockpit position.

[0029] Furthermore, a battery 6 is provided inside the main shell.

[0030] Furthermore, a touch screen display 7 is installed on the surface of the main shell, and the touch screen display 7 is electrically connected to the mainboard 5 through the battery 6.

[0031] Furthermore, a button 9 is provided on the main shell.

[0032] Furthermore, warning lights 4 are installed on both sides of the main shell.

[0033] Furthermore, a DC interface 10 and a data transmission interface 11 are provided on one side of the main housing.

[0034] The DC interface 10 is used to charge the device.

[0035] Among them, the signal obtained by analysis is processed and amplified by the main board 5, and the alcohol concentration is calculated. The result can be transmitted to the background server through the data transmission interface 11 or the wireless module 8. At the same time, the test result is synchronously displayed on the touch screen 7, or a warning is given through the warning light 4 on the utility model.

[0036] Beneficial effects of the utility model:

[0037] The utility model adds a speed measurement module 1 and an infrared imaging module 2 to the module assembly, uses the speed measurement module 1 to accurately predict the next position of the moving vehicle in advance, and calculates the position relationship between the driver and the ground in the driving vehicle based on the infrared imaging module 2 and adjusts the angle of laser detection in time, so as to achieve accurate measurement and reduce the risk of mismeasurement, improve the sensitivity of detection, predict the position information of the vehicle at the next moment of passing, lock the position of the driver, adjust the measurement angle of the laser detection alcohol module 3 in time, select the appropriate optical path route to quickly measure the alcohol concentration in the cab space, and solve the problem of laser measurement of alcohol concentration in moving vehicles.

[0038] The working principle of this utility model:

[0039] like Figure 4 As shown, when a car enters point A at a speed of v0, the speed measurement module 1 in this device starts to calculate the car speed. When the car reaches point B, the average speed v1 is calculated. At the same time, the infrared imaging module 2 is used to lock the driver's position. At the same time, the laser alcohol detection module 3 starts to work to detect the alcohol concentration in the space where the driver is located. At the same time, the information processing center calculates the arrival time points of points C and D based on the current average speed of the car v1. The laser alcohol detection module 3 automatically selects the appropriate optical path route for the second, third or multiple confirmations and comparisons to prevent misdetection and missed detection.
