Detailed Description
The primary objectives of the present application are: when the vehicle is designed to run, the identification point positions on the running line are shot through the shooting device, the shot identification point positions are compared with the pre-stored identification point positions, accordingly, the station information corresponding to the shot identification point positions is obtained, information interaction with other systems is not needed, and the vehicle can independently obtain the position of the vehicle.
The identification point position can be understood as a picture of each station on the vehicle operation line, and the picture is a unique identification of each station so as to be distinguished from other stations. For example, the picture of the post-sea station can display two Chinese characters of 'post-sea', the picture of the window station of the world can display four Chinese characters of 'window of the world', and the picture of the window station of the world can also display graffiti with a special decoration style in the station. Of course, the actual representation of the picture is not limited thereto.
It should be understood that the subject of the present application for carrying out the above-mentioned primary object is a running vehicle, on the basis of which the vehicle accomplishes the above-mentioned operations by means of its own equipment without the aid of external means. The vehicles include but are not limited to rail vehicles such as subways, light rails, trams, and the like.
Therefore, the application is equivalent to adding an automatic station identification function to the vehicle, and in an application scenario, the implementation manner of the function includes but is not limited to: a test script is programmed in advance, and can be actually expressed as a software or an application program, and then the software or the application program is installed in an operating system of a vehicle console (or referred to as a vehicle station), so that a setting interface of the vehicle console can display an option of 'automatic station identification', and a driver can correspondingly turn on or off the option by operating a button, sliding a slider and the like. After the function is started, the vehicle console controls equipment such as a shooting device to automatically execute the method of each embodiment below.
The technical solutions of the embodiments of the present application are clearly and completely described below with reference to the accompanying drawings. The following embodiments and technical features thereof may be combined with each other without conflict.
Fig. 1 is a schematic flowchart of a station identification method according to an embodiment of the present application. As shown in fig. 1, the station identifying method includes the following steps S11 to S14.
S11: the vehicle prestores identification point positions used for identifying all stations on the operation line of the vehicle, wherein the identification point positions comprise pictures of the stations on the operation line.
For a certain operation line, pictures of all stations are manually collected in advance, each station can collect pictures of multiple angles and multiple positions, the identification point position of each station comprises multiple pictures of multiple angles and multiple positions, and then the pictures are stored in storage equipment of a vehicle, so that the corresponding relation between the station and the pictures (identification point positions) is established.
The vehicle can finish the collection of the pictures, specifically, in the process that the ATS system and the SMD server are both in normal position recognition at the debugging or commissioning stage, the vehicle starts its own shooting device, such as a camera, to shoot the pictures of each station, or shoots the images through a vehicle data recorder and clips the pictures of each station, and then selects the pictures meeting the requirements as the identification points according to the picture recognition technology and stores the pictures.
The shooting device can be a front camera arranged at the front part of the vehicle and/or a rear camera arranged at the rear part of the vehicle. Correspondingly, the following step S12 can also use the shooting device to shoot the identification point on the operation line.
S12: and shooting the identification point position on the running line by the shooting device of the vehicle when the vehicle runs.
For rail traffic such as subways, the arrival time of each station is stored in advance by vehicles, and whether the vehicles arrive at the station or not can be known according to the arrival time. Of course, the present application may also monitor whether the vehicle enters the station through its own auxiliary devices, including but not limited to microwave radar, light sensors, etc. Taking a microwave radar as an example, the microwave radar emits electromagnetic waves outwards, the electromagnetic waves are shielded and returned by the platform, the microwave radar calculates the distance between the vehicle and the platform according to the time for emitting and receiving the electromagnetic waves, and the vehicle determines whether the vehicle enters the station according to the distance. And for the vehicles such as the subway running in the underground tunnel, when the light sensor detects that the light is obviously enhanced, the vehicles are determined to enter the station.
In this step, the angle and position of the shot image are the same as the angle and position of the previously stored picture, and even if there is a deviation, the deviation must be within the recognizable range.
S13: and the vehicle compares the shot identification point location with the pre-stored identification point location.
S14: and the vehicle acquires the identification point location matched with the shot identification point location and displays the station information identified by the shot identification point location.
When the shot picture is matched with at least one picture stored in advance, the vehicle determines that the shot identification point location is successfully matched with the identification point location stored in advance, and at the moment, the vehicle acquires the station information corresponding to the shot identification point location according to the corresponding relation stored in advance, such as the station name, the station name of the next station and the time required for the scheduled arrival.
According to the method and the device, the vehicle can independently know the position of the vehicle without information interaction with other systems such as an ATS system and the like, and real-time site display is carried out.
In order to improve the accuracy of the recognition result and ensure "universal loss" of the vehicle operation safety, the above-described site recognition method may be simultaneously operated with the ATS system and the SMD (server including the SMD, the same applies hereinafter). That is, the present application may compare the position information obtained by the above-described method (referred to as shot recognition method) with the position information obtained based on the ATS system and the SMD, and display the site according to the comparison result. For example, when the position information determined by the two methods is inconsistent, the present application determines that the station recognition based on the ATS system and the SMD has a failure based on the position information obtained by the shooting recognition method, and the present application is based on the shooting recognition method for the distance after the line is operated.
In an actual application scene, the viewing angle and the position of the shooting device are easy to change due to factors such as vehicle shaking, the situation that the shot identification point location is not matched with the pre-stored identification point location easily occurs, at the moment, the vehicle can select the last successfully-matched station, acquire the next station on the operation line and display the station information of the next station. This operation of the vehicle may be accomplished by a custom algorithm that is pre-stored in the vehicle system. For example, the vehicle operation line comprises two adjacent sites of a window in the world and a sea behind, and when the vehicle enters the sea behind station, if the two sites are not matched, the vehicle can automatically select the next site of the window in the world, namely the sea behind station, as a site needing to be displayed currently according to a pre-stored line operation diagram. And, upon leaving the "back sea" station, the vehicle automatically treats the "back sea" station as the "last successfully matched station," and so on.
