Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 is a system module diagram of the present invention. As shown in FIG. 1 , the method of this embodiment may include:

Divided into several message groups.

Specifically, the grouping rule is that the two adjacent items in each information group have the same location information target route, the same driving route, the distance between the two locations is less than or equal to the first preset number of stations, and the positioning time is less than or equal to Preset positioning time.

step 1e, starting navigation based on navigation information in a preset loading mapping table; when the information navigation unit and the stop board end are not kept in the same local communication network in the communication range in the process of carrying out the position sharing operation by the information navigation unit and the main control unit of the stop board end, the method further comprises the following steps:

step 1f, re-determining the position information of the user, and comparing whether the distance between the updated position information and the position information of the stop board end exceeds a communication distance threshold value, wherein a calculation formula of the distance between the position information of the user and the position information of the stop board end is (1):

where dis represents a distance between the location information of the user and the location information of the stop board end, (x) ₁ ,y ₁ ) Position information of the stop board end, (c) _i ,d _i ) To update all location information in the first 1s, (c) _m ,d _m ) Is position information in 1s at different millisecond time, and m belongs to [1,i ]]；

Step 1g, if not, the user side reads the identification information again through WIFI, and the local communication network architecture is completed again; if yes, periodically sending position information to surrounding station board terminals, and repeating the steps 1a to 1e until the user determines to stop the selected service.

2. The interactive intelligent electronic stop board system according to claim 1, wherein the authentication data of the local communication network is generated by extracting the characteristics of the user's characteristic data and combining with the time stamp data, the characteristic data at least comprises one or a combination of face recognition data and fingerprint recognition data, the authentication code is generated according to the formula (2),

wherein l _m (. Star) denotes a twin network trained using contrast loss, f _r (original word) watchThe cross entropy training convolutional network is used, r 'and b' represent serialized data, r is face recognition data uploaded currently, b is fingerprint recognition data, g is timestamp data, and rz is an authentication code.

3. The interactive intelligent electronic stop board system according to claim 1, wherein the obtaining of the congestion degree information of the bus route comprises three steps,

step 2a, dividing the bus into different areas, arranging a thermal imaging collector in each area, and collecting images in the bus through the thermal imaging collectors;

step 2b, transmitting the images acquired by the thermal imaging acquisition device to a thermal imaging processor, identifying high-temperature areas in the bus space through data processing, and dynamically measuring and calculating the space occupancy rate of each area;

and 2c, averaging the space occupancy of each area to obtain the crowding degree of the bus.
