Problems solved by technology

However, during the running of the train, especially when encountering obstacles such as tunnels, it may occur that the GPS signal cannot be received, resulting in the inability to continuously locate the train, or the received GPS signal is relatively weak. The positioning accuracy is poor due to the situation

Embodiment 1

[0116] Such as figure 1 As shown, it is a flow chart of the vehicle positioning method provided in the embodiment of the present application. The execution subject of the vehicle positioning method may be an electronic device. The specific steps of the above vehicle positioning method are as follows:

[0117] S101. Utilize the millimeter-wave radar installed on the target vehicle to transmit a detection signal to the target object, and receive the detection signal reflected by the target object.

[0118] Here, considering that the millimeter-wave radar has the characteristics of small size, light weight, high spatial resolution and high stability, the millimeter-wave radar originally used in the military field can be applied to the vehicle positioning of the vehicle provided by the embodiment of the present application. method. Considering the specific application scenarios of the vehicle positioning method provided in the embodiment of the present application, in the embodim...

Embodiment 2

[0150] refer to Figure 4 , in a specific application, combined with the mapping relationship between the position range information of each object and the range change information of each object, as well as the established mapping relationship between each object set and each positioning base station, determine the target range range change information mapping target The specific steps of location range information are as follows:

[0151] S401. After receiving the positioning signal by using the geomagnetic sensor provided on the target vehicle, determine the target positioning base station that transmits the positioning signal;

[0152] S402. Based on the mapping relationship between each object set and each base station, determine the target object set mapped by the target positioning base station; the target object set includes at least one target object;

[0153] S403. According to the mapping relationship between the position range information of each target object and...

Embodiment 3

[0158] In a specific implementation, an indicator label can be set on the target object, and the indicator label can be used to verify the target position range information determined in the first embodiment, and can also indicate the distance information corresponding to the target object, so as to control the target according to the distance information The vehicle performs the corresponding action.

[0159] Specifically, it can be as follows Figure 5 The method shown is to use the indicator label on the target object to verify the target position range information, wherein the specific steps are as follows:

[0160] S501. Transmitting a first indication signal to an indication tag set on the target object;

[0161] S502. When receiving the response signal returned by the indication tag according to the first indication signal, extract the actual position range information indicating the target object carried in the response signal;

[0162] S503. Verify the target locati...

Abstract

The invention provides a vehicle positioning method and device, electronic equipment and a storage medium. According to the method, a millimeter wave radar arranged on a target vehicle emits a detection signal to a target object, and receives a detection signal reflected by the target object; target distance amplitude change information corresponding to the target object is determined based on thedetection signal reflected by the target object; and according to mapping relation between position range information of different objects and different distance amplitude change information, targetposition range information mapping the target distance amplitude change information is determined, and position information of the target vehicle is determined based on the determined target positionrange information. Thus, the problem that GPS positioning causes incapability of continuous positioning or low positioning accuracy is solved, the vehicle can be positioned continuously, and the positioning accuracy is higher.

Description

technical field [0001] The present application relates to the technical field of positioning, in particular, to a vehicle positioning method, device, electronic equipment and storage medium. Background technique [0002] With the development of the economy and the improvement of people's living standards, trains have gradually become the preferred means of transportation for people's daily travel due to their advantages such as fast running speed, good comfort, and high cost performance. When the train is running, it needs to locate its own position at any time, so as to achieve the purpose of effectively controlling its own operation, for example, whether it needs to change the track, whether it is about to enter the station, etc. [0003] In the prior art, a global positioning system (Global Positioning System, GPS) is usually used for real-time positioning of the train. However, during the running of the train, especially when encountering obstacles such as tunnels, it m...
