The first diagnostic device 102a, the second diagnostic device 102b and the third diagnostic device 102c may be different types of diagnostic devices, and different types of diagnostic devices have different functional emphasis on vehicle diagnosis, so that diagnosis of the vehicle through different diagnostic devices can improve the efficiency of diagnosis and maintenance. The specific method for diagnosing and maintaining each diagnostic device is as follows:
the first diagnostic device 102a sends indication information to the connection box 101 after establishing a connection relation with the connection box 101 through a trigger operation and a ZigBee protocol, and sends the indication information to the vehicle 100 associated with the connection box 101 after the connection box 101 receives the indication information sent by the first diagnostic device, wherein the indication information is used for starting diagnosis of the vehicle.

An interaction schematic diagram of a vehicle diagnosis method in a ZigBee mode provided in an embodiment of the present application is described below with reference to fig. 2, please refer to fig. 2.
Step S201, the first diagnostic equipment establishes a connection relation with a connection box through a trigger operation and a ZigBee protocol;
specifically, the first diagnostic equipment comprises a ZigBee terminal module, and the connecting box comprises a ZigBee main equipment module and a micro control unit; and establishing a connection relation with the connection box through a trigger operation and a ZigBee protocol. The first connection box can enable the ZigBee terminal device to enter a networking mode through triggering operation, the triggering operation can be to operate an interface button on a display interface of the first diagnosis device, and the first connection box can be added into a network where a ZigBee master device module in the connection box is located. The networking mode can be a tree network, and the tree network comprises a coordinator, a plurality of routers and terminals. The tree network can be seen as a plurality of star networks, a central node forming the star network can be seen at each branch (a router with nodes), each child device can only communicate with a parent node of the child device, and the parent node at the highest level is a coordinator. In a tree network, a coordinator builds the whole network, and a router serves as a junction point to spread the network outwards in a tree. The nodes form a multi-hop network through the intermediate routers, and the capacity and the robustness of the network are good. The ZigBee master device module can be a coordinator in a tree network, and the ZigBee terminal module can be a terminal in the tree network.
It can be understood that, for the first diagnostic device, the connection relationship is established with the gateway through the trigger operation and the ZigBee protocol; for the connection box, a connection relation is established with the first connection box through a networking mode and a ZigBee protocol.
Step S202, the connection box allocates a short address to the first diagnostic equipment;
specifically, after the ZigBee terminal module of the first diagnostic device joins the network in which the ZigBee master device module of the connection box is located, the ZigBee master device module may respectively assign a unique short address to the first diagnostic device through the networking mode. The distributed short address has a corresponding relation with the ZigBee terminal, and is used for marking the ZigBee terminal module. The ZigBee master device module of the connection box may assign short addresses to a plurality of diagnostic devices joining a network in which the ZigBee master device module is located, and the short addresses assigned to each diagnostic device are different.
Step S203, the first diagnostic equipment sends instruction information to the connection box;
specifically, the method comprises the following steps: the indication information is used for starting diagnosis of the vehicle associated with the connection box; the first diagnosis equipment sends indication information to the connection box through the ZigBee terminal module in the first diagnosis.
Step S204, the connection box sends instruction information to the vehicle associated with the connection box;
specifically, after receiving the indication information, the ZigBee master device module in the connection box sends the indication information and the short address allocated to the first diagnostic device to the micro control unit in the connection box through the serial port, and the micro control unit in the connection box receives and lifts the short address and the indication information to serve as one element in the queue and stores the short address and the indication information into the sending queue. And the sending task created by the micro control unit in the junction box traverses the sending queue, and the indication information in the element is taken and sent to the vehicle associated with the junction box.
Step S205, the vehicle associated with the connection box sends fault information to the connection box;
in particular, since the sending task created by the micro-control unit of the junction box traverses the sending queue, the indication information of the elements stored in the sending queue is taken to be sent to the vehicle associated with the junction box. Therefore, after the vehicle associated with the connection box receives the indication information, the fault information of the vehicle is generated according to the response of the indication information, and then the fault information is sent to the connection box through the created sending queue.
Step S206, the connection box sends fault information to the first diagnosis equipment;
specifically, after the connection box receives the fault information, the micro control unit of the connection box sends the fault information and the short address in the element to the ZigBee main device in the connection box, and the ZigBee main device in the connection sends the fault information to the first diagnostic device.
Optionally, the sending the fault information to the first diagnostic device includes: and sending fault information to the first diagnostic equipment according to the short address.
Specifically, since the connection box assigns a short address to the first diagnostic apparatus after establishing a connection relationship with the first diagnostic apparatus, it is possible to transmit the failure information to the first diagnostic apparatus based on the short address.
And step S207, the first diagnosis device receives the fault information sent by the connection box and diagnoses the fault information.
Specifically, the fault information includes fault data of the vehicle, and after the ZigBee terminal module in the first diagnostic device receives the fault sent by the ZigBee main device module in the connection box, the first diagnostic device can diagnose the vehicle according to the fault information.
It should be noted that, because of the networking mode and the ZigBee protocol, the connection box may connect a plurality of diagnostic devices, and the plurality of diagnostic devices may diagnose the vehicle associated with the connection box according to the method of the first diagnostic device.
It will be appreciated that the ZigBee master device module and ZigBee terminal module referred to above are modules using the ZigBee protocol.

Wherein the indication information is used to initiate a diagnosis of the vehicle 300. After the vehicle 300 receives the instruction information, the ECU of the vehicle 300 may generate failure information in response to the instruction information, and then send the failure information to the mcu 303 in the junction box through the failure diagnosis interface of the vehicle 300. The micro control unit 303 may send fault information and a short address of each diagnostic device to the ZigBee master module 302 in the junction box 301. The ZigBee master module 302 may analyze the short address and the fault information, and send the fault information to the first diagnostic device 305a, the second diagnostic device 305b, and the third diagnostic device 306d according to the short address of each diagnostic device.
