[0036] Please refer to image 3 , image 3 Shows the flow chart of the method for vehicle location acquisition provided by the first embodiment of the present invention, the following will focus on image 3 The flow shown is described in detail, and the method includes:

[0037] Step S110: the vehicle positioning tag sends a first signal to the WIFI probe, and the vehicle positioning tag is used to be installed on the vehicle to mark the vehicle.

[0038] As an implementation of this embodiment, a vehicle location tag is provided on the vehicle to be monitored, and the vehicle location tag is used to identify the vehicle. It can be understood that one vehicle location tag corresponds to only one vehicle. At the same time, in the predetermined area where the vehicle needs to be monitored, a WIFI probe is set to receive the signal sent by the vehicle positioning tag, wherein the WIFI probe is a fixed WIFI probe device, which has low cost and can be used in any environment dep...

[0048] Please refer to Figure 4 , Figure 4 Shows the flow chart of the method for vehicle location acquisition provided by the second embodiment of the present invention, the following will focus on Figure 4 The flow shown is described in detail, and the method includes:

[0049] Step S210: when the vehicle location tag is disconnected from the battery, the vehicle location tag sends a second signal to the WIFI probe.

[0050] As an implementation of this embodiment, the vehicle positioning tag is set in the monitored vehicle and coupled with the storage battery in the vehicle, that is, the positive and negative power lines of the vehicle positioning tag are connected to the positive and negative terminals of the storage battery inside the monitored vehicle, This battery is used to power the vehicle locator tag. Preferably, the vehicle positioning tag supports various specifications such as 12V and 24V.

[0059] Please refer to Figure 5 , Figure 5 Shows the flow chart of the method for vehicle location acquisition provided by the third embodiment of the present invention, the following will focus on Figure 5 The flow shown is described in detail, and the method includes:

[0060] Step S310: The vehicle location tag determines the state of the vehicle.

[0061] In this embodiment, a vibration detection device is pre-installed in the vehicle positioning tag, and the vehicle positioning tag judges the state of the vehicle through the signal detected by the vibration detection device. It can be understood that when the vibration detection device detects a vibration signal, it indicates that the vehicle is in a moving state or in a starting state, and when the vibration detection device does not detect a vibration signal, it represents that the vehicle is in a stationary state.

[0062] Step S320: When the vehicle positioning tag determines that the vehicle is in motion, send ...

Abstract

The embodiment of the invention provides a method and a system for vehicle positioning acquisition and relates to the technical field of positioning. The method comprises the following steps: firstly, a first signal is transmitted to a WIFI probe through a vehicle positioning label, wherein the vehicle positioning label is mounted on a vehicle to label the vehicle; then, the WIFI probe obtains an MAC address, the signal strength and the signal direction of the vehicle positioning label according to the first signal and transmits the MAC address, the signal strength and the signal direction as well as a longitude and a latitude of the WIFI probe to a positioning server; finally, the positioning server calculates position information of the vehicle positioning label according to the MAC address, the signal strength and the signal direction as well as the longitude and the latitude. The method and the system for vehicle positioning acquisition, provided by the embodiment of the invention, realize a positioning scheme with low cost and multi-environment suitability.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a method and system for obtaining vehicle positioning. Background technique [0002] There are many vehicle positioning needs in all walks of life in the current society. At present, the mainstream positioning solutions all need to carry positioning tags with identification functions on the positioning vehicles. Based on the positioning tags, there are many realization schemes for vehicle positioning technology, mainly including GPS-based Or the positioning scheme of Beidou technology and the positioning scheme based on RFID technology. [0003] Vehicle positioning based on GPS or Beidou technology, using the GPS / Beidou receiving module in the target vehicle to receive satellite positioning information to obtain its own position, and then send the positioning data to the remote background through the cellular network to achieve target positioning and positioning infor...
