In order to make the technical solutions in the embodiments of the present disclosure better understood 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 diagram of a vehicle automatic driving test process according to an embodiment of the disclosure. In a default state (state 1), a test vehicle needing automatic driving test is connected with the vehicle management platform through an external network so as to carry out data communication with the vehicle management platform. The extranet 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 of the test vehicle to the vehicle management platform. In state 2, the test vehicle disconnects from the extranet and establishes a connection with the code server storing the test file package through the intranet, 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 can access the intranet and obtain the test document package through the intranet only under specific conditions that transmission of the test document package is required between the test vehicle and the code server, and the test vehicle is not desired to access the intranet under other conditions. Therefore, when the test file package is successfully acquired, the network connection state of the test vehicle is switched to the state 3, that is, the test vehicle is disconnected from the intranet and is restored to the connection with the extranet, so that the automatic driving test is performed. And entering a state 4 when the test meets certain conditions, such as the test is completed or the test progress reaches a certain progress node, disconnecting the test vehicle from the external network, and switching to the internal network. At this time, the test vehicle can be connected with 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 illustrative only and is not intended to be limiting of the present disclosure.
It can be seen that in the above process, a series of network switching between the intranet and the extranet is required for the test vehicle. In the related art, most test vehicles are only provided with an external network, and the random and free switching of the two networks cannot be realized.
Based on this, the disclosed embodiment provides a network access system for vehicle automatic driving test, as shown in fig. 2, the system includes:
a router 201 provided on the test vehicle 20 for providing a first network access service;
the wireless network card 202 is arranged on the test vehicle 20 and used for establishing connection with the wireless network access point 10 in the specified area to provide a second network access service when the test vehicle 20 enters the specified 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 package under the condition of accessing the second network; the vehicle-mounted industrial personal computer 203 can operate the test file package under the condition that the vehicle-mounted industrial personal computer is connected to the first network, so that the automatic driving test can be performed on the test vehicle 20.
The test vehicle 20 of the disclosed embodiment may be any vehicle that requires automated driving tests, such as an automobile, a school bus, a truck, and the like. The router 201 may be provided on the test vehicle 20 to provide a first network access service for the test vehicle 20 through the router 201, so that the on-board 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 extranet) such as a 3G network, a 4G network, or the like. The router 201 can be connected with the vehicle-mounted industrial personal computer 203 in a wired or wireless mode. The test vehicle 20 may access the designated data receiving end via the first network for data transmission with the designated data receiving end.
The wireless network card 202 can also be arranged on the test vehicle 20, so that a second network access service is provided for the test vehicle 20 through the wireless network card 202, and the vehicle-mounted industrial personal computer 203 is accessed to a 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. The wireless network card 202 may be disposed outside the vehicle body of the test vehicle 20 (for example, on the roof), and connected to the vehicle-mounted industrial personal computer 203 through a USB extension cord or an antenna, so as to reduce the signal strength of the wireless network card 202 in the vehicle body.
The vehicle-mounted industrial personal computer 203 can access the first network or the second network and realize different functions under the condition of accessing different networks. Accessing one of the first network and the second network does not mean that the other must be disconnected, for example, the on-board industrial personal computer 203 accesses the second network and does not mean that the on-board industrial personal computer 203 is disconnected 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 that of the first network, and in the case of simultaneously accessing the first network and the second network, the vehicle-mounted industrial personal computer 203 is provided with a service through a network with a higher priority. Of course, when the on-board industrial personal computer 203 is connected to one of the first network and the second network, the other may be disconnected.
The process of accessing the first network and the second network by the vehicle-mounted industrial personal computer 203 can be manually controlled, for example, when a test vehicle enters the designated area, a test operator manually accesses the second network on the vehicle-mounted industrial personal computer 203, and when an automatic driving test is required or when other networks are required to be accessed, the test operator manually accesses the first network on the vehicle-mounted industrial personal computer 203. Besides, the vehicle-mounted industrial personal computer 203 can be controlled to automatically access the first network or the second network. The test vehicle can only access the second network at the designated place and acquire the test file packet, so that the safety of the test file packet 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 of using binary packages, the risk of source code leakage is further reduced.
In some embodiments, the system further includes a vehicle management platform 204, configured to acquire the real-time position of the test vehicle 20 when the vehicle-mounted industrial personal computer 203 accesses the first network, and control the vehicle-mounted industrial personal computer 203 to access the second network when it is detected that the real-time position of the test vehicle 20 enters the designated area. Through the mode of this embodiment, can realize controlling on-vehicle industrial computer 203 automatic access second network, need not the on-vehicle industrial computer 203 of artificial operation and carry out the network switching, reduced the human cost to network switching efficiency has been improved.
The vehicle-mounted industrial personal computer 203 can be connected with the vehicle management platform 204 through a first network so as 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 point O in the map 301, and the designated area 302 (a circular area enclosed by a dotted line in the figure) may be a network coverage area of the wireless network access point 10, a range intersecting the network coverage area of the wireless network access point 10, or a sub-area within the network coverage area of the wireless network access point 10. At time t1, the test vehicle 20 is located at position P1 in the map 301, and at time t2, the test vehicle 20 is located at position P2 in the map 301. Since P2 is located in the designated area 302, the vehicle management platform 204 can 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 also send access information (e.g., an account number, a password, an 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. Under the condition that the access information comprises the access duration, the vehicle-mounted industrial personal computer 203 can start timing under the condition that the second network is successfully accessed, and automatically disconnect the second network under the condition that the timing is finished. Further, the vehicle-mounted industrial personal computer 203 can also automatically access the first network under the condition that the second network is disconnected. By the mode, manual switching between the two networks is not needed, automatic switching between the two networks can be achieved, switching efficiency is improved, and labor cost is saved.
The access information of the second network may correspond to the identification information of the designated area. The number of designated areas may be multiple and different designated areas may be located in different locations of the city, e.g., one designated area located in the south of the city, two designated areas located in the west of the city, and three designated areas located in the east of the city. By setting the designated areas in 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 acquisition of the test file package is facilitated.
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. Therefore, different test vehicles can be provided with services through different wireless network access points, the burden of a single wireless network access point is relieved, and personalized customized test services can be provided for different test vehicles conveniently.
The access information of the second network may also correspond to identification information of a test file package to be downloaded by the test vehicle. For example, the second network is accessed through different wireless network access points so as to obtain different test file packages, so that on one hand, data safety is improved through data isolation, and on the other hand, personalized customized test services are provided for different test vehicles.
The vehicle management platform can acquire identification information of the designated area, which is sent by the vehicle-mounted industrial personal computer under the condition of accessing the first network, identification information of the test vehicle, identification information of a test file packet and other preset information which needs to be downloaded by the test vehicle, and sends access information of the second network to the vehicle-mounted industrial personal computer 203 based on the preset information. The preset information can be sent to the vehicle management platform 204 by the vehicle-mounted industrial personal computer 203 under the condition that the vehicle-mounted industrial personal computer is connected to the first network, and after the vehicle management platform 204 receives the preset information, the vehicle-mounted industrial personal computer sends the connection information of the second network based on the preset information. For example, a test vehicle may be registered with the vehicle management platform 204 in advance, and when registering, preset information such as identification information of the selected designated area, identification information of the test vehicle, identification information of a test file package required to be downloaded by the test vehicle, and the like is submitted to the vehicle management platform 204, and the registration interface of some embodiments is as shown in fig. 4.
The vehicle-mounted industrial personal computer 203 may 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 obtained without manual operation, the test file package can be remotely downloaded, and workers do not need to carry the mobile storage equipment comprising the test file package to go to a test vehicle for file package deployment. Specifically, the vehicle-mounted industrial personal computer 203 may request the code server to download the test file package, for example, the vehicle-mounted industrial personal computer 203 may obtain a 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 on-board industrial personal computer 203 may send identification information of a required test file packet to the code server, so that the code server searches for a corresponding test file packet based on the identification information of the test file packet and pushes the test file packet to the on-board 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 in the case of receiving a test file package acquisition instruction sent by the on-board 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, and configured to control 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 and a mobile phone, and may also be a central control on a test vehicle. When obtaining the test file packet, a test operator may input a storage address of the test file packet on an 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 obtains the test file packet from the storage address.
As shown in fig. 6, is a timing diagram of the interaction between the vehicle and the vehicle management platform according to the embodiment of the present disclosure. In step 601, the test vehicle may register vehicle information, including vehicle identification information (e.g., license plate number), identification information of the test task performed, identification information of the designated area, and the like, with the vehicle management platform while accessing the first network. In step 602, the test vehicle may report its real-time location when accessing the first network, so that the vehicle management platform compares the real-time location of the vehicle with the location of the designated area in step 603. In the case where the vehicle management platform determines that the vehicle enters the designated area, the vehicle management platform may send access information of the second network in the designated area to the test vehicle, so that the test vehicle is switched from the first network to the corresponding second network in step 605. After successful access, the test vehicle may request the test package from the code server in step 606 and receive the test package returned by the code server in step 607, and then deploy the test package in step 608. After deployment is completed, the test vehicle can access the first network, and the vehicle management platform sends a test starting instruction to the test vehicle to start automatic driving test. Under the condition that the automatic driving test is completed or the progress of the automatic driving test reaches a preset progress node, the vehicle-mounted industrial personal computer 203 can be switched to the second network, and test data generated in the automatic driving test process are uploaded to the test management platform based on the second network. In the case that the test vehicle leaves the designated area or the test vehicle is disconnected from the second network, the first network can be switched to again, so that automatic switching from the second network to the first network is realized.
The one or more steps executed by the test vehicle can be executed by a vehicle-mounted industrial personal computer on the test vehicle, and can also be executed by a control terminal connected with the vehicle-mounted industrial personal computer. For example, vehicle information can be registered, vehicle positions can be reported, and test file packets can be requested through a vehicle-mounted industrial personal computer or a control terminal. The sequence of some steps in the above embodiments may be adjusted, and some steps may also be omitted, for example, the test vehicle may report the vehicle position first, and then register the vehicle information, or not register the vehicle information. The step of accessing the second network may be controlled by the vehicle management platform or may be performed manually; the step of accessing the first network can be automatically executed by the vehicle-mounted industrial personal computer under the condition of meeting a certain trigger condition, and can also be manually executed.
As shown in fig. 7, an embodiment of the present disclosure further provides a network access method for vehicle automatic driving test, which is applied to a vehicle-mounted industrial personal computer in the system according to any embodiment of the present disclosure, and the method includes:
step 701: under the condition that a test vehicle enters a designated area, switching a vehicle-mounted industrial personal computer from a first network which is accessed currently to a second network, and acquiring a test file packet stored in a cloud server through the second network; the access service of the second network is provided through the wireless network access point of the designated area;
