Embodiment 1
[0080] Such as figure 2 As shown; the GPS navigation module is used to obtain the starting point and end point of logistics transportation, plan the navigation path, and send the navigation path to the display module for data navigation;
[0081] The GPS navigation module communicates with the data acquisition module, and the data acquisition module is used to collect vehicle data while driving, and transmits the vehicle data to the data analysis module. The vehicle data includes the driving direction, driving speed and real-time position of the vehicle;
[0082] The data analysis module is used to receive vehicle data and analyze the vehicle data to obtain the deviation value of the vehicle. The specific analysis steps are:
[0083] Step 1: Obtain the deviation angle of the vehicle and mark G1; specifically include:
[0084] S11: Set the starting position of the vehicle as the coordinate origin, and establish a plane two-dimensional coordinate system;
[0085] S12: Mark th...
Embodiment 2
[0097] Such as image 3 As shown; the fuel quantity monitoring module is used to monitor the fuel quantity of the vehicle in real time, and the specific monitoring steps of the fuel quantity monitoring module are as follows:
[0098] P1: Obtain the current fuel volume of the vehicle and mark the current fuel volume as L1;
[0099] P2: Compare the current oil volume L1 with the standard oil volume threshold;
[0100] If L1≤the threshold of standard oil volume, it is in the state to be verified;
[0101] P3: When in the state to be verified, obtain the real-time location of the logistics vehicle and the end location of the planned path; calculate the path length between the real-time location and the end location in the planned path, and mark it as the remaining path length L2;
[0102] P3: Obtain the driving speed G2 of the vehicle;
[0103] Obtain the fuel consumption value of the vehicle to maintain the current driving speed and mark it as H1; use the formula L3=G2×L1 / H1 t...
Embodiment 3
[0122] Such as Figure 4 As shown; the behavior monitoring module is used to record the situation of the driver in real time during the driving process, obtain the real-time video information of the driver, and analyze the real-time video information. The specific analysis steps are as follows:
[0123] VV1: Process real-time video information to obtain driver's facial image information;
[0124] VV2: judge the disappearance time of facial image information;
[0125] When the disappearance time of the driver's facial image information is greater than the preset time value ET1, it is determined that the driver is in a distracted state, and a safety flameout instruction is generated;
[0126] VV3: Take a piece of video and process each frame in the video; calibrate the ROI of the eye area from the facial image information, and judge whether the eyes are open; the specific judgment method is:
[0127] VV31: mark the area of the eye region ROI as A;
[0128] VV32: Obtain the ...
