In order to better understand the technical solutions in the embodiments of the present disclosure and make the above objects, features and advantages of the embodiments of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings.
FIG. 1 is a schematic illustration of a vehicle autopilot testing process according to an embodiment of the present disclosure. In the default state (state 1), the test vehicle, which is required to perform the autopilot test, establishes a connection with the vehicle management platform through the extranet for data communication with the vehicle management platform. The external network may be an open network such as the internet, for example, a 4G network. The test vehicle can report the position, speed, license plate number and other information to the vehicle management platform. In state 2, the test vehicle disconnects from the external network and establishes a connection with the code server storing the test file package through the internal network so as to acquire the test file package from the code server. In order to improve data security, it is generally desirable that the test vehicle only access the intranet under specific conditions such as transmission of the test file packet between the test vehicle and the code server, and obtain the test file packet through the intranet, while in other cases, the test vehicle does not wish to access the intranet. Therefore, in the case where the test package is successfully acquired, the network connection state of the test vehicle is switched to state 3, that is, the test vehicle is disconnected from the intranet and resumes the connection with the extranet, thereby performing the automatic driving test. In case the test meets certain conditions, for example, the test is completed, or the test progress reaches a certain progress node, state 4 is entered, the test vehicle disconnects from the external network and switches to the internal network. At this time, the test vehicle may be connected to the test management platform through the intranet, and test data generated in the automatic driving test process is sent to the test management platform. Those skilled in the art will appreciate that the embodiment shown in fig. 1 is merely illustrative and not intended to limit the present disclosure.
It can be seen that in the above procedure, a test vehicle is required to perform a series of network switches between the intranet and extranet. In the related art, most of test vehicles only carry an external network, and two kinds of networks cannot be switched freely and freely.
Based on this, the disclosed embodiment provides a network access system for vehicle autopilot testing, as shown in fig. 2, the system comprising:
A router 201 provided on the test vehicle 20 for providing a first network access service;
a wireless network card 202 disposed on the test vehicle 20, configured to establish a connection with the wireless network access point 10 of the designated area to provide a second network access service when the test vehicle 20 enters the designated area; and
The vehicle-mounted industrial personal computer 203 is used for accessing a first network through the router 201 or accessing a second network through the wireless network card; the vehicle-mounted industrial personal computer 203 can acquire a test file packet under the condition of accessing the second network; the vehicle-mounted industrial personal computer 203 can run the test file package to perform the automatic driving test on the test vehicle 20 when accessing the first network.
The test vehicle 20 of the disclosed embodiments may be any vehicle that requires an autopilot test, such as an automobile, school bus, truck, etc. A router 201 may be provided on the test vehicle 20 to provide a first network access service to the test vehicle 20 through the router 201, so that the in-vehicle industrial personal computer 203 accesses the first network through the router 201. The first network may be a public wireless communication network (referred to as an external network) such as a 3G network, a 4G network, or the like. The router 201 may be connected to the in-vehicle industrial personal computer 203 by wired or wireless means. The test vehicle 20 may access the designated data receiving end through the first network for data transmission with the designated data receiving end.
A wireless network card 202 may also be disposed on the test vehicle 20 to provide a second network access service for the test vehicle 20 through the wireless network card 202, so that the vehicle industrial personal computer 203 accesses the second network through the wireless network card 202. The second network may be a dedicated wireless network (referred to as an intranet) during the autopilot test procedure. The wireless network card 202 may be disposed outside the vehicle body of the test vehicle 20 (e.g., on the roof of the vehicle) and connected to the vehicle-mounted industrial personal computer 203 through a USB extension line or an antenna, so as to alleviate the problem of reduced signal strength of the wireless network card 202 in the vehicle body.
The vehicle-mounted industrial personal computer 203 can access to the first network or the second network, and realize different functions under the condition of accessing to different networks. Wherein accessing one of the first network and the second network does not mean disconnecting from the other, for example, accessing the vehicle-mounted industrial personal computer 203 to the second network does not mean disconnecting the vehicle-mounted industrial personal computer 203 from the first network. Different priorities may be set for the first network and the second network, for example, the priority of the second network is set to be higher than the priority of the first network, and in the case of accessing the first network and the second network simultaneously, the service is provided to the in-vehicle industrial personal computer 203 through the network with the higher priority. Of course, when one of the first network and the second network is connected, the in-vehicle industrial personal computer 203 may be disconnected from the other.
The process of accessing the first network and the second network by the vehicle-mounted industrial personal computer 203 may be manually controlled, for example, when the test vehicle enters the designated area, the test operator manually accesses the second network on the vehicle-mounted industrial personal computer 203, and when an automatic driving test is required or other conditions requiring access to the first network, the test operator manually accesses the first network on the vehicle-mounted industrial personal computer 203. In addition, the vehicle-mounted industrial personal computer 203 can be controlled to automatically access the first network or the second network. Because the test vehicle can only access the second network and acquire the test file package at the appointed place, the safety of the test file package is improved, and the risk of data leakage is reduced. The test file package may be a binary package or a source code package. In case a binary package is employed, the risk of source code leakage is further reduced.
In some embodiments, the system further includes a vehicle management platform 204, configured to obtain a real-time position of the test vehicle 20 when the on-board industrial personal computer 203 accesses the first network, and control the on-board industrial personal computer 203 to access the second network when the real-time position of the test vehicle 20 is detected to enter the specified area. By means of the method, the vehicle-mounted industrial personal computer 203 can be controlled to automatically access the second network, network switching is not required to be performed by manually operating the vehicle-mounted industrial personal computer 203, labor cost is reduced, and network switching efficiency is improved.
The on-board industrial personal computer 203 may establish a connection with the vehicle management platform 204 through a first network to perform data interaction with the vehicle management platform 204. As shown in fig. 3, a positioning device (e.g., a GPS positioning device) on the test vehicle 20 may collect the position information of the test vehicle 20 in real time, and report the position information to the vehicle management platform 204 through the on-board industrial personal computer 203. The wireless network access point 10 of the designated area 302 is located at the O point in the map 301, and the designated area 302 (a circular area surrounded by a dotted line in the figure) may be a network coverage area of the wireless network access point 10, or may be a range intersecting with the network coverage area of the wireless network access point 10, or may be a sub-area within the network coverage area of the wireless network access point 10. At time t1, the position of the test vehicle 20 in the map 301 is P1, and at time t2, the position of the test vehicle 20 in the map 301 is P2. Since P2 is located in the designated area 302, the vehicle management platform 204 may control the on-board industrial personal computer 203 to access the second network. For example, the vehicle management platform 204 may send a network switching instruction to the on-board industrial personal computer 203, so that the on-board industrial personal computer 203 accesses the second network.
Further, the vehicle management platform 204 may further send access information (e.g., account number, password, access duration, etc.) of the second network to the on-board industrial personal computer 203, so that the on-board industrial personal computer 203 accesses the second network based on the access information of the second network. In the case that the access information includes the access duration, the vehicle-mounted industrial personal computer 203 may start timing when the second network is successfully accessed, and automatically disconnect the second network when the timing is ended. Further, the vehicle-mounted industrial personal computer 203 can automatically access the first network under the condition of disconnecting the second network. Through the mode, manual switching between two networks is not needed, automatic switching of the two networks can be realized, the switching efficiency is improved, and meanwhile, the labor cost is saved.
The access information of the second network may correspond to identification information of the designated area. The number of designated areas may be plural, and different designated areas may be located in different orientations of the city, for example, designated area one located in the south of the city, designated area two located in the west of the city, and designated area three located in the east of the city. By setting a plurality of designated areas with different directions, different designated areas can be selected according to the position of the test vehicle to acquire the test file package, so that the test file package is convenient to acquire.
The access information of the second network may also correspond to identification information of the test vehicle. For example, different test vehicles may access the second network through different wireless network access points. In this way, different test vehicles can be provided with services through different wireless network access points, so that the burden of a single wireless network access point is reduced, and personalized customized test services can be conveniently provided for different test vehicles.
The access information of the second network may also correspond to identification information of a test file package that needs to be downloaded by the test vehicle. For example, the second network is accessed through a different wireless network access point so as to acquire a different test file package, thus improving data security through data isolation on one hand and facilitating personalized customized test services for different test vehicles on the other hand.
The vehicle management platform may obtain the identification information of the designated area sent by the vehicle-mounted industrial personal computer when the vehicle-mounted industrial personal computer is connected to the first network, the identification information of the test vehicle, the preset information such as the identification information of the test file package required to be downloaded by the test vehicle, and the like, and send the access information of the second network to the vehicle-mounted industrial personal computer 203 based on the preset information. The preset information may be sent to the vehicle management platform 204 by the vehicle-mounted industrial personal computer 203 under the condition of accessing the first network, and after the vehicle management platform 204 receives the preset information, the vehicle management platform sends the access information of the second network to the vehicle-mounted industrial personal computer based on the preset information. For example, the test vehicle may register with the vehicle management platform 204 in advance, and at the time of registration, the identification information of the selected designated area may be submitted to the vehicle management platform 204, where the preset information such as the identification information of the test file package that needs to be downloaded by the test vehicle is shown in fig. 4, where the registration interface of some embodiments is shown in fig. 4.
The vehicle-mounted industrial personal computer 203 can acquire the test file package from the code server through the second network in response to successful access to the second network. Therefore, the test file package can be automatically acquired without manual operation, and can be downloaded remotely, and a worker does not need to carry the mobile storage device comprising the test file package to a test vehicle for file package deployment. Specifically, the vehicle-mounted industrial personal computer 203 may request to download the test file package from the code server, for example, the vehicle-mounted industrial personal computer 203 may obtain a uniform resource locator (Uniform Resource Locator, URL) of a storage address of the test file package in the code server, and access the corresponding storage address based on the URL to obtain the test file package. For another example, the vehicle-mounted industrial personal computer 203 may send the identification information of the required test file package to the code server, so that the code server searches the corresponding test file package based on the identification information of the test file package and pushes the test file package to the vehicle-mounted industrial personal computer 203. The code server may download the test file package from the cloud server in advance, or download the test file package from the cloud server upon receiving the test file package acquisition instruction sent by the in-vehicle industrial personal computer 203. In some embodiments, the cloud server comprises a code server.
In some embodiments, as shown in fig. 5, the system further includes a control terminal 205, connected to the vehicle-mounted industrial personal computer 203, for controlling the vehicle-mounted industrial personal computer 203 to access the first network or the second network. The control terminal 205 may include an operation interface for a user to perform various operations, such as inputting access information of the second network, selecting a test file package to be downloaded, manually switching the first network or the second network, inputting a URL of a storage address of the test file package, submitting registration information of the test vehicle to the vehicle management platform 204, and the like. The control terminal 205 may be an electronic device such as a tablet computer or a mobile phone, or may be a central control on a test vehicle. When acquiring the test file package, the test operator may input a storage address of the test file package on the operation interface of the control terminal 205, and the control terminal 205 sends the storage address to the vehicle-mounted industrial personal computer 203, so that the vehicle-mounted industrial personal computer 203 accesses the storage address, and acquires the test file package from the storage address.
