[0002] According to TSG81-2022 "Technical Safety Regulations for Special Vehicles within the Site (Factory)", off-road tourist sightseeing vehicles (hereinafter referred to as "sightseeing vehicles") refer to self-propelled passenger vehicles with more than 4 wheels, no tracks and no overhead lines, no less than 6 seats (including driver seats) and used for tourist sightseeing operation services, including sightseeing vehicles and sightseeing trains. Sightseeing vehicles adopt a non-enclosed body structure. During driving, dangerous behaviors such as passengers' bodies exceeding the range of the body and not wearing seat belts may affect the safety of passengers. Traditional standardized sightseeing vehicles are difficult to detect passengers' dangerous behaviors in a timely manner, and monitoring passenger behavior norms requires a lot of energy and time from the driver or safety officer. The driver's driving attention may be distracted during the vehicle's driving, and dangerous behaviors of passengers cannot be completely avoided.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0034] In this embodiment, when the safety belt used in the sightseeing vehicle is fastened, it is necessary to continuously apply force to pull the safety belt from one side to the fastening position of the fixed end on the other side.

[0035] like Figure 1 As shown, the utility model is a sightseeing vehicle passenger dangerous behavior detection device, including a control module and a passenger distribution detection module, an infrared detection module, a seat belt status detection module, a display module, a voice broadcast module, a wireless communication module and a data storage module respectively connected thereto.

[0036] Among them, the passenger distribution detection module includes multiple pressure sensors. Pressure sensors are installed in the center of the bottom of the seat and the backrest of each vehicle. The number of each pressure sensor corresponds to the specific seat number of the vehicle. The passenger distribution detection module outputs the detected pressure value to the control module in real time. The control module monitors the passenger distribution according to whether the pressure value exceeds the set threshold. Because the passenger wears a seat belt and his back is close to the seat back, two sensors are set. When both sensors receive pressure values, the controller determines that there is a passenger to prevent misjudgment caused by placing other objects on the seat.

[0037] The infrared detection module includes multiple groups of sensor transmitters and receivers installed on both sides of the vehicle. The same group of transmitters and receivers are installed on one side of the vehicle. They are used to detect whether the passenger's body parts exceed the range of the vehicle body during the vehicle startup process. Once a passenger is detected leaning out of the target area, information is transmitted to the control module, and the control module sends a reminder signal to the display module and the voice broadcast module.

[0038] The seat belt status detection module includes multiple tension sensors. A tension sensor is installed at the fixed end of each seat and seat belt connection in the vehicle. The number of each tension sensor corresponds to the specific seat number of the vehicle. It is used to detect whether the passenger has fastened the seat belt and output the detection result to the control module. When the continuous tension of the seat belt does not exceed the set threshold, the continuous tension will send a high-level instruction to the control module. The control module determines the seat number of the abnormal passenger based on the number of the tension sensor that issued the instruction. The control module sends an instruction to the display module, and the threshold is set according to that provided by the sensor manufacturer.

[0039] The display module specifically uses an OLED display screen, which is installed at the driver's central control screen position or within the safety officer's field of vision, and receives the information output by the control module. The control module distinguishes between occupied seats and vacant seats based on the preset vehicle layout information and passenger distribution information, and displays them on the OLED display screen. Figure 2 As shown, the OLED display shows the passenger distribution map and distinguishes between occupied and vacant seats. Yellow indicates the driver's seat. If the passenger has fastened his seat belt and his body does not exceed the range of the vehicle body, the seat will be displayed in red; blue indicates an empty seat;

[0040] When a passenger leans onto the car body, the image displayed on the OLED display screen flashes as a whole, and the voice broadcast module gives a reminder until the infrared detection module detects no abnormality, at which point the OLED display screen stops flashing and the voice broadcast module stops giving a reminder; when a passenger does not wear a seat belt, in the passenger distribution map displayed on the OLED display screen, the seat corresponding to the abnormal passenger will be slightly enlarged and flash continuously to alert the driver or safety officer, and the voice broadcast module gives a reminder until the seat belt detection module detects no abnormality, at which point the seat corresponding to the abnormal passenger will stop flashing and the voice broadcast module stops giving a reminder.

[0041] It also includes a power supply module, which is connected to the above modules and is used to supply power to each module.

[0042] The wireless communication module is connected to the control module through a data connection, and is also connected to the mobile phone TCP server data to receive data transmitted by the control module and wirelessly transmit the data to the mobile phone TCP server. The wireless module enables the device to communicate with the mobile phone through a TCP connection. Relevant staff can monitor the behavior of passengers in sightseeing vehicles in real time and query the records of passengers' dangerous behaviors through the mobile phone client. The data storage module is used to receive and store the data transmitted by the control module. The information sent by the control module to the wireless communication module and the data storage module includes all the information collected by the passenger distribution detection module, the infrared detection module and the seat belt status detection module.

[0043] like Figure 3 As shown, the central processor of the control module is an STM32F407ZGT6 microprocessor, which adopts the ARM Cortex-M4 core and integrates a wealth of peripherals; the infrared detection module adopts the TCC29 light curtain sensor, which has high detection accuracy, fast response speed and strong anti-interference ability; the tension sensor model of the seat belt detection module is the HX711 tension sensor, which has high accuracy and can provide accurate force measurement results; the power supply module includes a DC-DC circuit, which converts the voltage of the input power supply into a working voltage that meets the requirements of the central processor, and then supplies power to the central processor.

[0044] The UARE0, UARE1 and UARE2 interfaces of the central processor STM32F407ZGT6 are connected to RS232 chips, and then connected to the serial ports 1, 2 and 3 of the control module respectively. Serial port 1 is connected to an external pressure sensor, serial port 2 is connected to an external TCC29 light curtain sensor, and serial port 3 is connected to an external HX711 tension sensor, so that the central processor can realize data serial communication with the pressure sensor, TCC29 light curtain sensor and HX711 tension sensor respectively. The voice broadcast module uses the SYN6288 voice module; the model of the wireless communication module is ESP8266, and the model of the data storage module is AT24C02.

[0045] The implementation steps of this embodiment are:

[0046] Step 1: The power module of the sightseeing vehicle detection device starts to supply power, and multiple pressure sensors output the detected pressure values ​​to the control module in real time. The control module monitors the passenger distribution according to whether the pressure value exceeds the set threshold.

[0047] Step 2: The seat belt status detection module detects whether the passenger has fastened the seat belt and outputs the detection result to the control module.

[0048] Step 3: The infrared detection module detects whether the passenger's body part exceeds the range of the vehicle body and outputs the detected abnormal passenger location information to the control module.

[0049] Step 4: The OLED display screen receives the data output by the control module and displays the passenger distribution map. The occupied positions and free positions are marked in the map. When a passenger does not wear a seat belt or his body exceeds the range of the vehicle body, the OLED display screen is highlighted and the voice alarm of the voice broadcast module sounds. The driver checks the OLED display screen to see whether all passengers have fastened their seat belts and whether their bodies exceed the range of the vehicle body. The driver can only set off if the passengers have fastened their seat belts and have not exceeded the range of the vehicle body. If a passenger does not wear a seat belt or his body exceeds the range of the vehicle body, the driver regulates the passenger's behavior until the passenger complies with the riding regulations. The OLED display screen displays normally, the alarm ends, and the driver sets off again.

[0050] Step 5: During driving, the passenger distribution detection module, the seat belt status detection module and the infrared detection module monitor the passenger status all the time. If a passenger is detected to have dangerous behavior, that is, the seat belt is not fastened or the body is beyond the range of the vehicle body, the OLED display and voice alarm module will promptly inform the driver or safety officer to remind the passengers to pay attention and regulate the passenger's behavior. Example 2

[0051] As another preferred detection method of the passenger distribution detection module, the passenger distribution detection module includes an infrared imaging camera module. The specific model of the camera module is OV5640. The camera module is installed in the center of the roof of the sightseeing car. It is used to take regular photos and videos inside the car during the start-up process of the vehicle. The frequency of regular photos is once every 1 second, which monitors the passenger distribution and outputs the passenger distribution information to the control module.

[0052] The controller is equipped with a method recorded in the publication number CN110040068A. Its algorithm adopts YOLOv2, which has a high accuracy rate for head and target detection. It determines the distribution of passengers in the car by analyzing the images taken by the infrared imaging camera unit, and analyzes the passenger position distribution status in combination with the pre-stored spatial structure diagram of the bus compartment. The data information is transmitted to the display screen. The passenger distribution map is displayed on the OLED display screen, and occupied and free seats are distinguished and marked.

[0053] like Figure 4 As shown, the light curtain sensor transmitting device 1 is installed behind the last row of passenger seats in the sightseeing vehicle, the light curtain sensor receiving device 3 is installed in front of the first row of passenger seats in the sightseeing vehicle, and the camera module is installed in the middle of the top of the sightseeing vehicle; for a sightseeing train with multiple carriages, a camera module of a passenger distribution detection module is installed at the top center of each carriage, and a transmitting device and a receiving device of an infrared detection module are installed on both sides of each carriage. Example 3

[0054] Different from Example 1, the infrared detection module also outputs the position information of the infrared disconnection to the control module. The control module determines which row on the left or right side the passenger is leaning out of based on the distance thresholds set in advance for each row and column. The control module transmits the information to the display module, and the display module informs and reminds the driver in text. Example 4

[0055] As another preferred detection method of the seat belt status detection module, a sensor can be used to detect whether the male and female buckles of the seat belt are fastened, and the detection result is sent to the controller, which determines whether the passenger has fastened the seat belt.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
