Technical Field

Background
In order to determine the position of the trailer and prevent the vehicle from being lost, a satellite positioning module is usually provided on the trailer, and the position of the trailer can be known through a satellite positioning system used by the satellite positioning module.
To save power, the satellite positioning module typically sends position information to the monitoring terminal at long intervals (e.g., every 24 hours) while the trailer is stationary. Only when the trailer moves, the trailer sends the latest position of the trailer to the monitoring terminal with a higher frequency.
Satellite Positioning generally employs a Global Positioning System (GPS), a Beidou Navigation System (BDNS), a galileo Navigation System, or other satellite Positioning systems. It should be noted that, in any satellite positioning system, the positioning accuracy is limited, for example, the positioning accuracy of the GPS is usually about 50-100 meters, and when a user needs to use a trailer in a stationary state or needs to repair a trailer parked at a certain place, the user needs to find the trailer first. In an actual scene, a range with a radius of 50 meters may cross a block, which brings certain difficulty to find a trailer in a static state, and therefore, how to improve the positioning accuracy of the trailer so as to quickly find the trailer in the static state is an urgent problem to be solved.

8. The method of claim 7,
when the schedule information includes the specified to-do-matters, determining a time (T1-T) corresponding to a predetermined time period T before the specified to-do-matters occurrence time T1 as the target time.
9. A method for repairing a trailer, said method being applied to repair N trailers dispersed at different locations, said N being a positive integer, said method comprising the steps of:
acquiring the position of each trailer obtained after positioning each trailer in the N trailers by using the positioning method of any one of claims 1 to 6;
and determining the maintenance sequence of the N trailers according to the position of each trailer in the N trailers.
10. A positioning device for a trailer, the positioning device comprising:
the positioning module is used for positioning the trailer to acquire the position information of the trailer;
the communication module is used for acquiring target time;
the first processing module is used for triggering the positioning module of the trailer to carry out continuous positioning to obtain a plurality of position information if the trailer is in a static state at the target moment; during continuous positioning, the acquisition frequency of the positioning module for the position information is greater than the acquisition frequency of the positioning module for the position information before the target moment when the trailer is in a static state; the plurality of position information is used to determine a position of the trailer in a stationary state.
