Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted positioning, and in particular to a small-sized vehicle-mounted positioning sharing system. Background Art

[0002] The small vehicle-mounted positioning sharing system is a system that connects small vehicles to a sharing platform through positioning technology and network communication. This system usually consists of three main components: vehicle-mounted equipment, positioning services and sharing platforms. The vehicle-mounted equipment is a device installed on the vehicle, usually including a global positioning system (GPS) receiver, a wireless communication module and a data processing unit. The device can receive satellite signals through GPS and calculate the vehicle's location information. At the same time, it can also send the location information to the server or sharing platform through the wireless communication module. The positioning service is a service for collecting and processing vehicle location data. It can store the vehicle's real-time location information on the server and provide query and analysis functions. The positioning service can also combine the location data with other information (such as vehicle status, driving speed, etc.) to achieve more intelligent vehicle management and scheduling;

[0003] An auxiliary vehicle positioning system shown in the publication number CN103162689B includes: a speed detection module for detecting and recording the movement speed of the vehicle; an acceleration detection module for detecting and recording the acceleration of the vehicle; an angle sensing module for detecting and recording the change in the movement direction of the vehicle; a magnetic sensing module for determining the directions of the geographic north and south poles and the movement direction of the vehicle; and the wireless communication module is also used to calculate the estimated position information of the vehicle;

[0004] In the above device, although the real-time movement status of the vehicle is detected and recorded in time by multiple sensors, when the GPS module is unlocked, the current position of the vehicle can be inferred based on the movement status of the vehicle and the longitude and latitude information of the last positioning. However, during its use, the positioning module and communication module in the system are separate and do not have an integrated device, which occupies the vehicle installation space. At the same time, the assembly structure of the equipment is cumbersome and not convenient for later maintenance and management. Summary of the invention

The torque of the torsion spring drives the winding roller to rotate, so that the released data cable can be automatically reeled up after the external force disappears.
