step 201: and receiving a connection request sent by the terminal equipment in a near field communication mode, wherein the near field communication mode is a communication mode used between the diagnostic equipment and the terminal equipment, and the connection request is sent when the terminal equipment touches the diagnostic equipment.
Near Field Communication (NFC) is a short-range high-frequency radio technology, and devices using the technology can exchange data in close proximity to each other. The technology is integrated and evolved from a non-contact Radio Frequency Identification (RFID) and an interconnection and intercommunication technology, combines the functions of an induction type card reader, an induction type card and point-to-point on a single chip, and can perform Identification and data exchange with compatible equipment in a short distance.
The terminal device can be specifically a smart phone, a tablet personal computer, a wearable device (such as an intelligent bracelet) and other devices with an NFC function, and a client APP of the diagnosis device is installed on the terminal device.
The diagnostic equipment can be an automobile diagnostic instrument.
In this embodiment, an NFC module may be set in the diagnostic device in advance, so that the diagnostic device has an NFC function, that is, the diagnostic device may establish a connection with a client of the diagnostic device installed on the terminal device in an NFC manner. Specifically, when the connection needs to be established, the user can hold the terminal device by hand and touch the diagnostic device, at this time, the terminal device can send a connection request to the diagnostic device based on the built-in NFC module of the terminal device, and then, the diagnostic device can receive the connection request sent by the terminal device based on the NFC module preset by the diagnostic device, that is, the diagnostic device receives the exercise-level request sent by the terminal device in an NFC manner.
