S202, matching is carried out according to the first voltage value and the second voltage value and preset safety conditions, and the fastening state of the safety belt after the passenger takes a seat is determined according to the matching result.
Specifically, the preset safety condition may be a preset voltage threshold, or may be that the voltage value is not 0. Optionally, the preset safety condition may be one or two; when the preset safety conditions are two, the detection terminal respectively matches the first voltage values at the two ends of the seat sensor and the second voltage values at the two ends of the safety belt sensor with the corresponding preset safety conditions. Suitably, the matching result may be that the first voltage values at the two ends of the seat sensor and the second voltage values at the two ends of the seat belt buckle are both greater than the preset voltage threshold, or that the first voltage values at the two ends of the seat sensor and the second voltage values at the two ends of the seat belt buckle are respectively greater than the corresponding preset voltage threshold.

and if the second voltage value exists, determining the fastening state of the safety belt after the passenger is seated according to the matching degree of the second voltage value and a preset fastening voltage threshold range.
3. The method of claim 2, wherein said determining whether a seated occupant is currently in the seat based on a match between the first voltage value and a predetermined seating voltage threshold range comprises:
if the first voltage value falls into a preset sitting voltage threshold range, determining that a seated passenger exists on the current seat;
determining the seat belt fastening state of the passenger after the passenger is seated according to the matching degree of the second voltage value and a preset fastening voltage threshold range, including:
and if the second voltage value falls into a preset fastening voltage threshold range, determining that the passenger on the current seat fastens the safety belt.
4. The method of claim 2, further comprising:
if the first voltage value is greater than the maximum value of the preset sitting voltage threshold range, it is determined that a seated passenger is currently on the seat, and the number of seated passengers is greater than 1.
5. The method according to any one of claims 1-4, further comprising:
and sending the safety belt fastening state of the current sitting passenger to the vehicle-mounted all-in-one machine so that the vehicle-mounted all-in-one machine displays the safety belt fastening state of the current sitting passenger.
6. The method according to any one of claims 1-4, further comprising:
sending a safety belt fastening state of a current sitting passenger to a vehicle-mounted all-in-one machine, so that the vehicle-mounted all-in-one machine determines an identifier of a seat, which is not fastened with a safety belt, in a vehicle according to the safety belt fastening state of the current sitting passenger and outputs reminding information according to the identifier; and the reminding information is used for reminding the passenger on the seat corresponding to the identifier to fasten the safety belt.
7. The method according to any one of claims 1-4, further comprising:
sending a safety belt fastening state of a current seated passenger to a background server so that the background server determines the seating rate of the current passenger in the vehicle and the safety belt fastening rate according to the safety belt fastening state of the current seated passenger;
or,
and sending the safety belt fastening state of the current sitting passenger to the vehicle command center station through the background server.
8. The method of any one of claims 1-4, wherein said obtaining a first voltage value across a seat sensor and a second voltage value across a seat belt sensor comprises:
according to a preset voltage acquisition period, a first voltage value at two ends of a seat sensor and a second voltage value at two ends of a safety belt sensor are acquired.
9. A detection terminal, characterized in that it comprises a transmitter, a memory and a processor, the memory storing a computer program, characterized in that the processor is adapted to carry out the steps of the method according to any one of claims 1-8 when executing the computer program.
10. A readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 8.
