In a possible implementation manner, the starting of receiving the broadcast information in step 301 includes: acquiring a vehicle identifier of a vehicle to be detected; and starting to receive the broadcast information according to the vehicle identification.
In the above embodiment, the Vehicle identifier of the Vehicle to be detected may be a Vehicle Identification Number (VIN) or a frame Number (VIN) of the Vehicle to be detected, which is abbreviated as a VIN code and is used for uniquely identifying the Vehicle to be detected. In different detection systems or different application scenarios, the vehicle identifier of the object to be detected can be set according to actual conditions, which is not limited in this application.
In an actual vehicle production line based on the VIN code of the vehicle identifier of the vehicle to be detected, the obtaining of the vehicle identifier of the vehicle to be detected may include setting a barcode containing information of the VIN code of the vehicle to be detected on the vehicle to be detected (for example, on both sides of the vehicle body or on a windshield right in front of the vehicle), and obtaining the VIN code of the vehicle to be detected by scanning the barcode on the vehicle after the detection device detects that the vehicle to be detected arrives. The method for acquiring the vehicle identifier of the vehicle to be detected may also include: the vehicle-mounted card is prepared for a vehicle to be detected, the vehicle-mounted card can be printed or comprises a two-dimensional code capable of acquiring VIN code information of the vehicle to be detected, the vehicle-mounted card always follows the vehicle to be detected in the whole detection process of the vehicle to be detected, and under the condition, when the detection equipment detects that the vehicle to be detected arrives, the VIN code of the vehicle to be detected is acquired by scanning the two-dimensional code on the vehicle-mounted card. Of course, other manners capable of acquiring the vehicle identifier of the vehicle to be detected may be included, and a corresponding method may be set according to different manners of acquiring the vehicle identifier of the vehicle to be detected, which is not limited in this application.

Thus, the binding relationship includes: the vehicle identification of the vehicle to be detected, the first identification of the vehicle-mounted equipment which establishes communication connection with the vehicle to be detected and the IP address of the vehicle-mounted equipment.
Based on the above example, assume a VCI bound with vehicle AaThe serial number of the equipment is 100001, and VCIaThe IP address of the device is 192.168.1.101; VCI binding with vehicle BbThe serial number of the equipment is 100002 and VCIbThe IP address of the device is 192.168.1.102, and the binding information stored in the server is shown in table 1 below:

Based on the above example, there is another possible embodiment, assuming that a PC in a device is detected1The sequence number in the received broadcast message is 100002, so that the PC is ready to receive1The serial number 100001, PC of the vehicle-mounted equipment which is acquired by the equipment from the server and is bound with the vehicle A to be detected1The broadcast signal received by the equipment is different from the serial number of the vehicle-mounted equipment which is acquired from the server and is bound with the vehicle A to be detected, and then the PC1The device will continue to parse the next broadcast message until it finds the vehicle device with serial number 100001, i.e. VCIa。
Based on the above example, a PC in a device is detected1Device and VCIaAfter establishing communication connection, PC1The device may respond to the VCI with a detection function on the deviceaAnd sending a diagnosis instruction corresponding to the detection function to diagnose the vehicle A to be detected.
It should be understood that if the PC in the device is detected1If the equipment has a detection function, sending a diagnosis instruction corresponding to the detection function to the vehicle A to be detected; when detecting a PC in the device1The device has a plurality of detection functions, and can sequentially send diagnosis instructions corresponding to the plurality of detection functions to the vehicle a to be detected.
In one embodiment, after the detecting device displays the diagnosis result, the method further includes: judging whether all the vehicles to be detected are detected; and if so, informing the server to disassociate the association relationship between the vehicle-mounted equipment and the vehicle identifier.
Exemplary, when the PC is1After the equipment finishes diagnosing the vehicle A to be detected, the PC1Equipment disconnection and VCI corresponding to the vehicle A to be detectedaTo enable PC1The device detects the next other vehicle to be detected.
PC1After the equipment finishes diagnosing the vehicle A to be detected, the vehicle to be detected sequentially passes through the PC according to the vehicle offline detection method in the embodiment2To PCmThe detection device is used for detecting the position of the equipment,PC2to PCmAnd the detection equipment sequentially sends corresponding diagnosis instructions to the identified vehicle-mounted equipment so as to diagnose the vehicle to be detected.
Referring to FIG. 8, assume PCmThe device is the last one of the test devices, then when the PC in the test device is testedmAfter the equipment finishes diagnosing the vehicle A to be detected, the PCmThe equipment sends a unbinding instruction to the server, wherein the unbinding instruction is used for informing the server to release the vehicles A and VCI to be detectedaThe association between them, i.e. the notification server deletes the 1 st record as stored in table 1. Thus, the VCI can be convertedaPulling out the OBD interface of the vehicle A to be detected or disconnecting the vehicle A to be detected from the VCIaTo enable VCIaDevice in idle state, VCI in idle stateaThe equipment can be used for connecting the next vehicle to be detected.
In the above embodiments of the present application, the diagnosis instruction is determined according to the detection item of the off-line detection specific station.
