Fig. 2 is a schematic flowchart of a first embodiment of a resistance configuration method of a diagnostic device according to the present invention. The invention provides a resistance configuration method of diagnostic equipment, which comprises the following steps:
s101: and acquiring a target vehicle identifier of the target detection vehicle.
In one particular implementation scenario, a target vehicle identification of a target detection vehicle is obtained, the target vehicle identification including at least one of a make, model, year of the vehicle, e.g., haver H62021, great wall, or eastern wind (light truck) EV 18. The target vehicle identification may be manually uploaded by a user or acquired after being recognized by an image or a wireless signal (e.g., bluetooth signal, infrared signal) of the target detection vehicle.
In one implementation scenario, the target vehicle identification is a vehicle VIN code. Vehicle Identification Number (or frame Number), abbreviated as VIN, is a group of seventeen letters or numbers, is a unique group of numbers used in automobiles, and can be used for identifying data such as manufacturers, engines, chassis serial numbers and other performances of automobiles. By adopting the VIN code, the data volume transmitted between the diagnostic equipment and the server can be effectively reduced, the transmission efficiency is improved, and the time delay is reduced.

The terminal resistance configuration information includes information on whether the target detection vehicle needs to have the terminal resistance configured by the diagnostic device, and may be represented by "0" or "1", or may be represented by "yes" or "no". Specifically, if the target detection vehicle is equipped with the device terminal resistor, the diagnosis device is not required to be equipped with the terminal resistor, and the diagnosis of the vehicle can be performed by directly connecting the target detection vehicle with the diagnosis device, for example, performing code reading, code clearing, data flow reading, special functions, and the like. If the target detection vehicle is not provided with the device terminal resistor, the diagnosis device needs to be provided with the terminal resistor, so that when the diagnosis device is connected with the target detection vehicle, the terminal resistor can be used as the device terminal resistor in the detection vehicle, and successful communication between the diagnosis device and the target detection vehicle is realized.

For example, a value of a certain parameter may be acquired to acquire whether the target detection vehicle needs the diagnostic device to set the termination resistance, and if iFlag is 0, it indicates that the diagnostic device is not needed to set the termination resistance, and if iFlag is 1, it indicates that the diagnostic device is needed to set the termination resistance.
And if the diagnosis equipment is required to set the terminal resistor, driving the lower computer to set the diagnosis equipment to be disconnected with the terminal resistor, connecting the diagnosis equipment with the target detection vehicle, and implementing a diagnosis process. If the diagnosis equipment is not required to be provided with the terminal resistor, the lower computer is driven to set the diagnosis equipment to be connected with the terminal resistor, when the diagnosis equipment is connected with the target detection vehicle, the terminal resistor can play a role in detecting the equipment terminal resistor in the vehicle, and the diagnosis equipment can successfully implement a diagnosis process.
In one implementation scenario, the termination resistance has a default resistance value of 120 Ω. The device termination resistance value depends on the impedance characteristics of the cable, independent of the length of the cable. RS-485/RS-422 cables are typically connected using twisted pair (shielded or unshielded) wires with corresponding termination resistances typically between 100 and 140 omega, typically 120 omega. Therefore, in this implementation scenario, the default resistance value is set to 120 Ω, so that the termination resistor can function as the device termination resistor.

The resistance of the termination resistor 212 is adjustable within a range of 110 ohms or more and 140 ohms or less.
