The invention discloses a system and method for determining the position occurrence moment of a device to be positioned, and the method comprises the steps: obtaining time information from a timing chip or an external timing tool when a positioning server receives a positioning period starting signal, directly calculating the moment when a data packet is received through employing a positioning time slot number and the time length of a positioning time slot, and taking the moment as the moment when the positioning tag transmits the positioning signal, so the specific time does not need to be frequently acquired, and the resources of the positioning server are saved. The positioning server is enabled to return the time information in the complete time format only in the specific time interval, and only sends the time information in two units of seconds and milliseconds when sending the position information every time, so transmission resources are saved. According to the invention, an additional testing device does not need to be arranged, the current absolute time does not need to be carried in the positioning signal, and the position occurrence time of the device to be positioned can be conveniently and reliably obtained while the complexity of the system is reduced, so that the positioning delay of the positioning system is accurately obtained.
Description
technical field [0001] The present disclosure relates to the field of positioning, and more particularly, the present disclosure relates to a system and method for determining the time at which a position occurs. Background technique [0002] With the rapid increase of data services and multimedia services, on the basis of short-distance high-speed wireless communication, people's demand for location information awareness is also increasing. Especially in complex environments, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots, mines, etc., or environments that require special requirements for personnel positioning, such as prisons, kindergartens, hospitals, nursing homes, etc., often require Determine the location information of mobile terminals or their holders, facilities and objects, and then use them for monitoring and management, security alarms, command and dispatch, logistics, telemetry and remote control, and emerg...
