Detailed Description
In the following description, numerous technical details are set forth in order to provide a better understanding of the present application. However, it will be understood by those skilled in the art that the technical solutions claimed in the present application may be implemented without these technical details and with various changes and modifications based on the following embodiments.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
A first embodiment of the present application relates to a test yard supervision system, the test yard comprising one or more test areas.
Optionally, the multiple test areas differ in road surface and road condition. For example, the various test zones may be, but are not limited to, one or more of a tarmac area, a spacious straight area, a cement area, a gravel area, a dirt area, a steep slope area of a curve.
Fig. 1 is a schematic structural diagram of a train yard supervision system according to an example of the present embodiment. The test yard monitoring system comprises a supervision server and a positioning terminal, wherein the positioning terminal is in communication connection with the monitoring server after being started; wherein the positioning module is pre-installed in the test vehicle before the test vehicle enters the test yard.
Specifically, as shown in fig. 1, the monitoring system for a test yard may include a plurality of positioning terminals, one positioning terminal may be detachably mounted on each test vehicle before the test phase, and the positioning terminal may be detachably mounted on a platform in front of a steering wheel of a driver, or may be made in a form similar to an earphone and worn by the ear of the driver; but is not limited thereto. The monitoring server records the unique identification of each positioning terminal. The unique identifier of the locating terminal can be used as part of the test vehicle identifier, for example, the test vehicle identifier is composed of a vehicle frame number and the unique identifier of the installed locating terminal. The vehicle under test can reliably communicate with the test server according to its identification.
After the test vehicle enters the test yard, the positioning terminal is mainly used for determining the position information of the test vehicle, and the position information is sent to the monitoring server through the communication connection with the monitoring server, and the mode that the positioning terminal sends various information to the monitoring server can be a real-time or timing mode, and can also be a mode that the monitoring server actively inquires the positioning terminal. In one embodiment, the positioning terminal has high-precision positioning differential resolving capability, and can realize sub-meter-level precision positioning by matching with a network RTK positioning differential broadcasting service.
Optionally, the monitoring server may further calculate and determine the driving speed, the driving direction, the acceleration and the like of the test vehicle according to the position information sent by the positioning terminal. For example, the positioning terminal uploads the real-time position according to the frequency once per second, and the monitoring server can calculate the running speed of the vehicle according to the position difference and the event difference of two points in front of and behind the vehicle; for example, the driving direction of the vehicle is judged by calculating the included angle between the direction vector of the lane and the driving vector of the vehicle.
The supervision server has various implementation manners, and may be one physical server, a combination of multiple physical servers, or a cloud serving as a server. And the mode that the server sends various information to the positioning terminal can be a mode that the server pushes the information, and can also be a mode that the positioning terminal actively inquires the server.
Further, as shown in fig. 1, the supervision server includes a rule setting module, a determination module, and a violation judgment module.
The rule setting module is used for setting the operation rule of the test vehicle in the corresponding test area in advance according to the test requirement of the test vehicle. It is considered that the kind of test area that may be selected differs for each test vehicle having attribute information (e.g., a highest speed attribute, an acceleration capability attribute, an uphill capability attribute, a braking capability attribute, a drivability attribute, etc.); for each test vehicle with the same performance index, the types of the test areas possibly selected are different due to different batches or different manufacturers; for the same test area, different running rules can be suitable for different test vehicles due to different performance indexes of the test vehicles; different operating rules may be appropriate for the same test vehicle, in different test zones. Therefore, different test requirements of each test vehicle are set by the rule setting module before entering the formal test, the rule setting module sets the operation rule of each test vehicle in the corresponding test area according to the respective test requirements of each test vehicle, which is very necessary, and the test order in the test yard can be ensured to be carried out orderly while the test requirements of each test vehicle are met.
The operation rule may include one or more rule types, and the rule types may be increased or decreased as desired. In one embodiment, the operation rule includes at least one or more of the following rule types: speed limit, illegal parking, no entry, fatigue driving, zone capacity overrun, reverse driving, an example of which is shown in table 1 below.

For a better understanding, the following description is given in conjunction with a specific example K: the details listed in this example K are mainly for convenience of understanding, and not for limiting the scope of the present application, the test yard in this example K includes 5 test areas, the following table 2 is an example of the first corresponding relationship, the following table 3 is an example of the second corresponding relationship, and 6 values in any one of the groups a 1-a 6, B1-B6, C1-C6, D1-D6, E1-E6, and F1-F6 in the examples are set according to the test performance index of each vehicle and the road surface and road condition of each designated test area.
TABLE 2

Optionally, the monitoring server further includes a storage module, configured to store a first correspondence between the identifier of each vehicle and each specified test area, and a second correspondence between each test area and the operation rule specified by each vehicle.
The determining module is used for determining the testing area where the testing vehicle is located according to the position information of the testing vehicle obtained from the positioning terminal and determining the operation rule of the testing vehicle in the testing area where the testing vehicle is located. For better understanding, the description continues with example K above: for a test vehicle marked as 001, in a stage of entering a test yard for testing, the monitoring server determines that the test vehicle is in the test area 1, 2 or 5 according to the real-time location information of the test vehicle obtained from the positioning terminal and the first corresponding relationship shown in table 2, and further determines the operation rule of the test vehicle in the test area 1, 2 or 5 according to the first corresponding relationship shown in table 2 and the second corresponding relationship shown in table 3.
Optionally, the determining module is further configured to, when the test vehicle enters any one of the test areas, push the operation rules (to be complied with) in the test area of the test vehicle to the location terminal of the test vehicle; the positioning terminal also comprises a prompting unit used for prompting the operation rule needing to be complied with and pushed by the determining module to the driver. Wherein the prompting unit can be a voice prompting unit or a display prompting unit.
And the violation judging module is used for judging whether the test vehicle has a behavior violating the operation rule according to the position information of the test vehicle and the operation rule in the test area where the test vehicle is located.
