Fig. 2 is a schematic flow chart of a first embodiment of a resistance configuration method of a diagnostic device provided by the present invention. The resistance configuration method of the diagnostic equipment provided by the invention comprises the following steps:
S101: and acquiring a target vehicle identification of the target detection vehicle.
In one specific implementation scenario, a target vehicle identification of a target detection vehicle is obtained, the target vehicle identification including at least one of a vehicle make, model, year, for example, great wall haverse H6 2021, or east wind (light truck) EV18. The target vehicle identification may be manually uploaded by the user or acquired by recognition of an image or wireless signal (e.g., bluetooth signal, infrared signal) of the target detection vehicle.
In one implementation, the target vehicle identification is a vehicle VIN code. The vehicle identification number (Vehicle Identification Number, or frame number), abbreviated as VIN, is a unique set of seventeen letters or numbers used on the vehicle and can be used to identify the manufacturer, engine, chassis number and other performance of the vehicle. The VIN code can effectively reduce the data volume transmitted between the diagnosis equipment and the server, improve the transmission efficiency and reduce the time delay.
S102: and sending the target vehicle identifier to a server, and receiving terminal resistance configuration information corresponding to the target vehicle identifier returned by the server.
In a specific implementation scenario, terminal resistance configuration information corresponding to the target vehicle identifier is stored in the server in advance, and after the target vehicle identifier is acquired, the corresponding terminal resistance configuration information is sent to the diagnostic device. The termination resistance configuration information includes information on whether or not the target detection vehicle needs to configure the termination resistance by the diagnostic device, and may be represented by "0", "1", or "yes" or "no". Specifically, if the target detection vehicle is provided with the device termination resistor, the diagnosis device is not required to be provided with the termination resistor, and the diagnosis device is directly connected with the target detection vehicle to perform vehicle diagnosis, for example, code reading, code clearing, data reading flow reading, special functions and the like. If the target detection vehicle is not provided with the equipment terminal resistor, the diagnosis equipment needs to be provided with the terminal resistor so that the terminal resistor can be used as the equipment terminal resistor in the detection vehicle when the diagnosis equipment is connected with the target detection vehicle, and successful communication between the diagnosis equipment and the target detection vehicle is realized.
S103: and driving the lower computer to set the connection relation between the diagnosis equipment and the terminal resistor according to the terminal resistor configuration information.
In a specific implementation scenario, the terminal resistance configuration information is parsed, so that whether the target detection vehicle needs the diagnosis device to set the terminal resistance is obtained, and the connection relation between the diagnosis device and the terminal resistance is set according to the condition that whether the target detection vehicle needs the diagnosis device to set the terminal resistance. For example, a value of a certain parameter may be acquired to acquire whether the target detection vehicle requires the diagnostic device to set the termination resistance, if iFlag =0, this indicates that the diagnostic device is not required to set the termination resistance, and if iFlag =1, this indicates that the diagnostic device is required to set the termination resistance.
If the terminal resistor is required to be set by the diagnosis equipment, the lower computer is driven to set the diagnosis equipment to be disconnected with the terminal resistor, the diagnosis equipment is connected with the target detection vehicle, and a diagnosis process is implemented. If the terminal resistor is not required to be set by the diagnosis equipment, the lower computer is driven to set the diagnosis equipment to be connected with the terminal resistor, and when the diagnosis equipment is connected with the target detection vehicle, the terminal resistor can play a role in detecting the terminal resistor of the equipment in the vehicle, and the diagnosis equipment can successfully implement a diagnosis process.
In one implementation, the termination resistor has a default resistance value of 120Ω. The device termination resistance value depends on the impedance characteristics of the cable, independent of the length of the cable. The RS-485/RS-422 cable is typically connected by twisted pair (shielded or unshielded) and has a corresponding termination resistance typically between 100 and 140 Ω, typically 120 Ω. Therefore, in this implementation scenario, the default resistance value is set to 120 Ω, so that the termination resistor can function as a device termination resistor.
As can be seen from the above description, in this embodiment, the diagnostic device includes a lower computer, in which a terminal resistor is provided, and the connection relationship between the diagnostic device and the terminal resistor is set according to whether the diagnostic device is required to set by the target detection vehicle, so that the detection efficiency can be effectively improved, the operation of adding the terminal resistor of the device to the vehicle is not required, and the detection cost is effectively reduced.
Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a second embodiment of the diagnostic device according to the present invention. The diagnostic device 20 is connected to the lower computer 21, the lower computer 21 includes a resistor configuration switch 211 and a terminating resistor 212, one end of the resistor configuration switch 211 is connected to the diagnostic device 20, the other end is connected to the terminating resistor 212, when the resistor configuration switch 211 is in the off state, the diagnostic device 20 is in a connection state with the terminating resistor 212, and when the resistor configuration switch 211 is in the on state, the diagnostic device 20 is in a disconnection state with the terminating resistor 212. The resistance of termination resistor 212 is adjustable over a range of greater than or equal to 110 ohms and less than or equal to 140 ohms. The lower computer 21 adjusts the resistance value of the termination resistor 212 according to the instruction of the diagnostic device 20.
Fig. 4 is a schematic flow chart of a second embodiment of a resistance configuration method of a diagnostic device provided by the present invention. The resistance configuration method of the diagnostic equipment provided by the invention comprises the following steps:

S203: and if the terminal resistor configuration information prompts that the terminal resistor needs to be configured, driving the lower computer to control the resistor configuration switch to be opened.
In a specific implementation scenario, if the target detection vehicle is not provided with a device terminal resistor, the diagnostic device needs to be connected with the terminal resistor, so that when the diagnostic device is connected with the target detection vehicle, the terminal resistor can be used as the device terminal resistor in the detection vehicle to realize successful communication between the diagnostic device and the target detection vehicle, and the lower computer is driven to control the resistor configuration switch to be opened to realize connection between the diagnostic device and the terminal resistor.

The resistance value may be a resistance value of a device termination resistance of the target detection vehicle or a resistance value approximately equal to the device termination resistance of the target detection vehicle. For example, the device termination resistor has a resistance of 110 ohms, and the resistance is 110 ohms.
The termination resistance configuration information further includes termination resistance configuration information of the target detection vehicle. The termination resistance configuration information also includes at least one of an OBD communication pin (e.g., pin number 6/14 or pin number 3/11) and a baud rate (e.g., 500K).
In other implementation scenes, the terminal resistor in the diagnosis equipment is an adjustable resistor, the resistor configuration switch further comprises a resistor adjuster with a resistor value adjusting function, the resistor value of the terminal resistor is set to be the resistance value according to the acquired resistor value, the purpose that the diagnosis equipment can accurately match the resistor requirements of vehicles of different types is achieved, the diagnosis operation can be smoothly and accurately carried out, the diagnosis cost is reduced, and the diagnosis efficiency and reliability are improved.
In other implementations, a termination resistor in the diagnostic device is initially set to a default value (e.g., 120 ohms), and a determination is made as to whether the resistance value in the termination resistor configuration information is the default value; if yes, the lower computer is driven to control the resistor configuration switch to be opened; if not, the lower computer is driven to control the resistor configuration switch to be opened, and the resistor regulator is used for regulating the resistance value of the terminal resistor connected into the diagnostic equipment, so that the resistance value of the connected terminal resistor is the same as the resistance value of the terminal resistor to be configured in the terminal resistor configuration information.
S204: and if the terminal resistor configuration information prompts that the terminal resistor is not required to be configured, driving the lower computer to control the resistor configuration switch to be closed.
In a specific implementation scenario, if the target detection vehicle is configured with a device terminal resistor, the diagnosis device is not required to be connected with the terminal resistor in the lower computer, and vehicle diagnosis can be performed by directly connecting the diagnostic device with the target detection vehicle, for example, code reading, code clearing, data reading, special functions and the like are performed, and the lower computer is driven to control the resistor configuration switch to be closed so as to disconnect the diagnostic device from the terminal resistor.
As can be seen from the above description, in this embodiment, the lower computer includes a resistor configuration switch, where the lower computer is connected with the terminal resistor through the resistor configuration switch, and the connection or disconnection between the diagnostic device and the terminal resistor is implemented by controlling the state of the resistor configuration switch, so that whether the diagnostic device sets the state of the terminal resistor and adjusts the resistance value of the terminal resistor can be flexibly adjusted, so that the detection efficiency can be effectively improved, and the diagnostic requirements of multiple vehicles can be satisfied.
