In the embodiment of the application, the test equipment is an upper computer, namely the test equipment can directly send out the control command. That is, the test equipment may issue operation commands to control the equipment connected thereto. The upper computer body can be, for example, a notebook computer, a desktop computer, a tablet computer, and the like.
In some embodiments, if the test device is connected to the to-be-tested car networking terminal, the test device may issue an operation command to control the test device. The to-be-tested car networking terminal is a car networking terminal which needs to be tested whether the function is normal or not, and the to-be-tested car networking terminal can be a V2X-Box, for example.
In the embodiment of the application, a user can determine whether the function of the internet of vehicles terminal to be tested is normal through the test equipment.
In this application embodiment, the setting signal may be a detection signal that the car networking terminal can acquire. Alternatively, the setting signal may be a vehicle speed signal, a temperature signal, a torque signal, or the like. The preset value represents a specific numerical value of the setting signal. For example, when the setting signal is a vehicle speed signal, the preset value represents a specific value of the vehicle speed signal, namely a vehicle speed value. The set signal may be generated by a test device, for example a vehicle speed signal with a vehicle speed of 50km/h (kilometers per hour) may be generated by a test device, so that the preset value is 50.
In some embodiments, the functions of the terminal under test may include a function of receiving and transmitting a signal, a function of encoding a signal, a function of parsing a signal, and the like.
In step 220, the to-be-tested vehicle networking terminal generates first information according to the setting signal.

Alternatively, the first Information may be one of BSM (Basic Safety Message) Information, RSI (Road Side Information) Information, RSM Information (Road Side Safety Message) Information, SPAT (Signal phase timing Message) Information, MAP (MAP Information) Information, and the like. The first information may be used to transmit basic information of the vehicle, such as vehicle speed information, steering information, braking information, etc. of the vehicle.
In the embodiment of the application, the vehicle networking terminal to be tested can obtain the preset value according to the setting signal, so that the specific numerical value of the basic information of the vehicle is determined, and the first information is generated according to the preset value.
In some embodiments, if the setting signal is a vehicle speed signal, the vehicle obtains a preset value, i.e., a specific value of the vehicle speed information, according to the setting signal, so as to generate the first information that the vehicle speed information is the preset value according to the preset value.
In some embodiments, the first information may be transmitted to other vehicles or devices in a broadcast manner, and in this embodiment, may be specifically transmitted to the reference vehicle networking terminal in a broadcast manner.
In the embodiment of the application, the first information includes a basic information field, and the content of the basic information field is set to be a preset value. It can be understood that the first information may further include other fields, which may be specifically set according to actual needs, and this is not limited in this embodiment of the application.
Specifically, after receiving the setting signal sent by the test equipment, the to-be-tested car networking terminal can analyze the setting signal to obtain the preset value in the setting signal, then generate first information with a basic information field as the preset value according to the obtained preset value, and broadcast the first information to send to the reference car networking terminal in order to send the preset value carried in the setting signal to the reference car networking terminal.
In some embodiments, in order to distinguish each of the to-be-tested car networking terminals, a unique ID, for example, 123456789, may be assigned to each of the to-be-tested car networking terminals, that is, an Identity Document (Identity number). Thus, the generated first information may further comprise a field of an identity code. Therefore, after the other equipment receives the first information, the to-be-tested vehicle networking terminal sending the information can be determined according to the identity code carried in the first information.
As an implementation mode, after receiving the setting signal, the to-be-tested Internet of vehicles terminal can analyze the content carried in the setting signal to obtain a preset value, and then packages the preset value to generate first information. Illustratively, the carried content in the setting signal includes information a, information B and information C, where the information B is a preset value, and the to-be-tested car networking terminal packages the information B to generate the first information.
As an implementation manner, after receiving the setting signal and analyzing the content carried in the setting signal to determine the preset value, the to-be-processed basic security information may be generated first, and then the content of the to-be-replaced field in the to-be-processed basic security information is replaced by the preset value, so as to generate the first information. The content of each field in the basic security information to be processed is a predetermined default value.
Illustratively, the preset value is X, the to-be-processed basic safety information generated by the to-be-tested internet-of-vehicles terminal includes a field a and a field B, the content of the field a is 1, the content of the field B is 2, and the to-be-replaced field is the field a, the content of the field a is replaced by the preset value, so that the generated first information includes the field a and the field B, the content of the field a is X, and the content of the field B is 2.
In some embodiments, the first information may be broadcast by the terminal of the vehicle networking under test through the communication device. In some embodiments, the communication device may include a 5G-V2X chip so that the first information may be broadcast to the surroundings in the form of a V2X signal.
In step 230, the reference internet of vehicles terminal generates second information according to the first information.
In this application embodiment, benchmark car networking terminal is used for treating the function at survey car networking terminal and detects, communicates with the car networking terminal that awaits measuring through benchmark car networking terminal, can detect the receiving and dispatching function at the car networking terminal that awaits measuring.
The reference car networking terminal is a normal-function car networking terminal, so that the reference car networking terminal can also comprise a transceiver device, a positioning device, a communication device, a main control device and other devices, and the functions of the devices corresponding to the car networking terminal to be tested are similar to those of the devices. Specifically, the reference internet of vehicles terminal can receive first reference safety information sent by the to-be-tested internet of vehicles terminal to the surrounding in a broadcast mode through the communication device.
The benchmark car networking terminal can receive the first information that awaits measuring car networking terminal sent, can resolve the first information simultaneously, obtains the information that carries in the first information to generate the second information according to the information that carries, then to the car networking terminal broadcast second information that awaits measuring around.
In the embodiment of the application, if the to-be-tested car networking terminal can receive the second information, it indicates that the function of receiving the signal by the to-be-tested car networking terminal is normal. If the to-be-tested Internet of vehicles terminal can determine that the second information is generated after the reference Internet of vehicles terminal receives the first information, it is indicated that the function of the to-be-tested Internet of vehicles terminal for sending the signal is normal.
In the embodiment of the application, after the reference internet of vehicles terminal receives the first information, the second information is generated according to the first information, in order to distinguish the generation basis of the second information, in the embodiment of the application, the second information may include an identification code field, wherein the content of the identification code field is set to be a preset value, so that different preset values can be set to distinguish the second information.
For example, a reference internet of vehicles terminal receives first information A1 sent by a first to-be-tested internet of vehicles terminal, wherein the first information A1 includes a first preset value; the reference Internet of vehicles terminal receives first information A2 sent by the second Internet of vehicles terminal to be tested, wherein the first information A2 comprises a second preset value. Further, the reference internet of vehicles terminal generates second information B1 according to the first information A1, wherein the identification code of the second information B1 is a first preset value; and the reference Internet of vehicles terminal generates second information B2 according to the second information A2, wherein the identification code of the second information B2 is a second preset value. Therefore, according to the identification code of the second information B1, namely the first preset value, it can be known that the second information B1 is generated by the reference internet of vehicles terminal according to the first information A1 sent by the first to-be-tested internet of vehicles terminal, namely the function of the first to-be-tested internet of vehicles terminal sending signal is normal. Similarly, according to the identification code of the second information B2, that is, the second preset value, it can be known that the second information B2 is generated by the reference internet of vehicles terminal according to the first information A2 sent by the second internet of vehicles terminal to be tested, that is, the function of the second internet of vehicles terminal to be tested for sending the signal is normal.
The number of the to-be-tested car networking terminals which leave the factory at present is large, and in order to distinguish each to-be-tested car networking terminal, the ID number of the identification code distributed to each to-be-tested car networking terminal is large, so that if the ID test function of the to-be-tested car networking terminal is normal, when a test signal carrying the ID of the identification code is sent to the test equipment, a large amount of memory in the test equipment can be occupied, and resource waste is caused. Therefore, the embodiment of the application uses the preset value with shorter digits to replace the ID under the same test principle, so that the condition of occupying the memory of the test equipment can be effectively reduced.
It can be understood that the second information may further include other fields, which may be set in actual need, and this is not limited in this embodiment of the application. In some embodiments, similar to the to-be-tested car networking terminal, the reference car networking terminal may also be, for example, a V2X-Box.
In some embodiments, similar to the first information, the second information may also be one of BSM information, RSI information, RSM information, spam information, MAP information, and the like.
In some embodiments, the second information is generated in a manner similar to that of the first reference security information, and is not described herein again.
In some embodiments, one reference internet of vehicles terminal may receive the first information broadcast by a plurality of internet of vehicles terminals to be tested at the same time. Furthermore, after the reference internet-of-vehicle terminal generates the second information, the reference internet-of-vehicle terminal can broadcast the second information to the surrounding through a communication device included in the reference internet-of-vehicle terminal, and the communication device in the to-be-tested internet-of-vehicle terminal can receive the second information broadcast by the reference internet-of-vehicle terminal.
In step 240, the vehicle networking terminal to be tested generates a test signal according to the second information.
In the embodiment of the application, the test signal is a signal which is generated and sent to the test equipment after the to-be-tested car networking terminal receives the second reference safety information sent by the reference car networking terminal.
In some embodiments, a plurality of vehicle networking terminals to be tested can be included in the test system of the vehicle networking terminal, and the test equipment can set a corresponding setting signal for each vehicle networking terminal to be tested. The preset values in the setting signals corresponding to different to-be-tested car networking terminals are different.
Optionally, the setting signal sent by the testing device to each terminal of the internet of vehicles to be tested may be manually set by the user, that is, the preset value in the setting signal is manually set by the user. For example, a to-be-tested internet of vehicles terminal a and a to-be-tested internet of vehicles terminal B exist, a user manually sets a preset value in a setting signal sent to the to-be-tested internet of vehicles terminal a to be 10, and manually sets a preset value in a setting signal sent to the to-be-tested internet of vehicles terminal B to be 20.
Optionally, if one testing device is connected to multiple (i.e., two or more) to-be-tested car networking terminals at the same time, setting signals with different preset values can be automatically set for each to-be-tested car networking terminal through a related algorithm.
Further, because the preset values in the setting signals received by each to-be-tested vehicle networking terminal are different, the preset values can be used as the identity codes of each to-be-tested vehicle networking terminal, so that the second information can comprise fields with the content being the identity codes, and the preset values in the first information are used as the identity codes.
In some embodiments, when the preset value represents a vehicle speed value, the range of the preset value may be determined according to the range of the vehicle speed. Illustratively, the vehicle speed ranges from 0km/h to 255km/h, and the preset value ranges from 0km/h to 255 km/h.
In some embodiments, after receiving the second information broadcast by the reference internet of vehicles terminal, the to-be-tested internet of vehicles terminal parses the second information to obtain an identification code of the second information, then uses the identification code as a to-be-tested value, generates a test signal according to the to-be-tested value, and finally sends the test signal to the test equipment through the CAN bus.
The test equipment can determine whether the function of the Internet of vehicles terminal to be tested is normal or not according to the value to be tested in the test signal.
In the embodiment of the present application, the test signal includes a value to be measured. It is to be understood that other contents may also be included in the test signal, which may be specifically set according to the actual situation, and is not limited herein.
In some embodiments, since the reference car networking terminal may receive signals broadcast by multiple car networking terminals to be tested at the same time, the reference car networking terminal may also broadcast multiple second information at the same time, that is, each car networking terminal to be tested may receive the second information sent by the reference car networking terminal to other car networking terminals to be tested. Therefore, in order to enable each Internet of vehicles terminal to be tested to accurately receive the second information sent to the terminal by the reference Internet of vehicles terminal, the Internet of vehicles terminal to be tested can judge the received second information before generating the test signal according to the second information, and determine whether to generate the test signal according to the judgment result.
Specifically, the to-be-tested vehicle networking terminal analyzes the received second information to obtain the identification code in the second information, namely, a preset value is obtained, and if the preset value is the same as the preset value in the setting signal received by the to-be-tested vehicle networking terminal, the received second information is determined to be a signal sent to the to-be-tested vehicle networking terminal, so that the to-be-tested vehicle networking terminal generates a test signal according to the second information.
Illustratively, if a first to-be-tested vehicle networking terminal and a second to-be-tested vehicle networking terminal are tested, the first to-be-tested vehicle networking terminal broadcasts first information A1 carrying a first preset value A1, and the second to-be-tested vehicle networking terminal broadcasts first information A2 carrying a second preset value A2. After receiving the first information A1 and the first information A2, the reference Internet of vehicles terminal generates second information B1 with the identification code being a first preset value A1 according to the first information A1, generates second information B2 with the identification code being a first preset value A2 according to the first information A2, and broadcasts the second information B1 and the second information B2 respectively.
Therefore, after the first to-be-tested vehicle networking terminal receives the second information B1, according to the identification code in the second information B1, it is determined that the second information B1 is generated by the reference vehicle networking terminal according to the first information A1, and therefore the first to-be-tested vehicle networking terminal generates a test signal according to the second information B1 and sends the test signal to the test equipment. Similarly, after the second information B2 is received by the second to-be-tested vehicle networking terminal, according to the identification code in the second information B2, it is determined that the second information B2 is generated by the reference vehicle networking terminal according to the second information A1, and therefore the second to-be-tested vehicle networking terminal generates a test signal according to the second information B1 and sends the test signal to the test equipment.
In step 250, the test equipment determines a test result of the to-be-tested vehicle networking terminal based on the test signal.
The test result comprises the function normality and the function abnormality of the to-be-tested car networking terminal.
As an implementation manner, after receiving the test signal, the test device analyzes the test signal to obtain a value to be tested in the test signal, and if the value to be tested is equal to a preset value set by the test device, it can be determined that the preset value is not changed in the process of receiving and sending the signal by the to-be-tested car networking terminal, so that it is determined that the function of the to-be-tested car networking terminal is normal. And if the value to be measured is different from the preset value, determining that the function of the Internet of vehicles terminal to be measured is abnormal.
For example, referring to fig. 4, the testing device first sets a preset value to X, and then generates a setting signal containing X and sends the setting signal to the to-be-tested car networking terminal. And the to-be-tested vehicle networking terminal generates first information containing X after receiving the setting signal and then broadcasts the first information. And after receiving the broadcast signal, the reference Internet of vehicles terminal generates second information with the identity code of X according to the first information and then broadcasts the second information. And the to-be-tested car networking terminal analyzes the broadcast signal after receiving the broadcast signal to obtain X, generates a test signal according to the X and sends the test signal to the test equipment. The test equipment judges whether X in the test signal is equal to a preset value set before or not after receiving the test signal, and if the X in the test signal is equal to the preset value, the function of the Internet of vehicles terminal to be tested is normal; and if not, indicating that the function of the Internet of vehicles terminal to be tested is abnormal.
As another embodiment, the testing process in the above embodiment can be implemented on the car networking terminal to be tested, so that the car networking terminal to be tested sends the test result to the test equipment as the test signal, and the test equipment can directly determine whether the function of the car networking terminal to be tested is normal according to the test result in the received test signal.
Specifically, the to-be-tested car networking terminal analyzes the second reference safety information after receiving the second reference safety information to obtain a preset value, compares the preset value in the second reference safety information with the preset value in the setting signal, and determines that the function of the to-be-tested car networking terminal is normal if the preset value in the second reference safety information is consistent with the preset value in the setting signal; and if the two are not consistent, determining that the function of the Internet of vehicles terminal to be tested is abnormal, generating a test signal according to the test result, and sending the test signal to the test equipment.
In this embodiment, the test apparatus generates a setting signal including a preset value; the vehicle networking terminal to be tested generates first information according to the setting signal; the reference Internet of vehicles terminal generates second information according to the first information; the identity identification code corresponding to the second information is a preset value; the vehicle networking terminal to be tested generates a test signal according to the second information; and the test equipment determines a test result of the to-be-tested vehicle networking terminal based on the test signal. Therefore, the identity identification code corresponding to the second information is set to be a preset value through the reference Internet of vehicles, and then whether the test signal determined according to the second information comprises the preset value or not is detected, so that whether the function of the Internet of vehicles terminal to be detected is normal or not is determined, and therefore the function of the Internet of vehicles terminal to be detected is rapidly detected.
