Background
The OBD system of the vehicle can monitor the running state of each system of the vehicle at any time, and once abnormity occurs, the OBD system can immediately send out a warning. When the system has a fault, the fault lamp or the warning lamp is turned on, data of all the sensors and the drivers are recorded, fault information is stored in the memory, the fault code can be read out through the diagnostic instrument and the program, and maintenance personnel can quickly and accurately determine the nature and the position of the fault according to the prompt of the fault code, so that the requirements of diagnosis and maintenance can be met to the greatest extent. Therefore, the diagnostic instrument is a powerful tool for vehicle maintenance workers to repair and remove the vehicle.
At present, there are many kinds of diagnosis instruments in the market, each of which is long, but the price of the diagnosis instrument is relatively high for maintenance personnel, and the cost is too high for purchasing all the models of diagnosis instruments, which is not practical.

If a maintenance person or a technician can remotely control the diagnostic apparatus, and diagnose or research and develop the diagnostic apparatus by using a non-local diagnostic apparatus, the cost can be greatly reduced, the utilization rate of the diagnostic apparatus is improved, and the realization basis of the remote control is that a real-time picture of the controlled diagnostic apparatus can be provided for a user, and the simulated touch screen operation of the user can be performed on the controlled diagnostic apparatus.
Existing remote control schemes are as follows: the method comprises the steps that a first terminal (a control end) and a second terminal (a controlled end) are both attached to an LTE network, after receiving a video call request sent by the second terminal, the first terminal returns a message of agreeing to control, a data transmission channel is established with the second terminal, the first wireless terminal receives a current screen image transmitted by the second terminal and displays the current screen image on a display screen of the first wireless terminal, when a user operates the first terminal, a touch screen coordinate is captured, a target coordinate on the second terminal is obtained through calculation according to the screen proportion of the first terminal and the second terminal and the touch screen coordinate on the first terminal, touch screen simulation operation is conducted on the second terminal, and the screen image of the second terminal is transmitted to the first terminal.
In the scheme, the controlled end initiates the control request, which is not applicable to the field of remote use of the vehicle diagnostic instrument, and in the field, a maintenance master or a research and development worker, namely the control end, generally initiates the control request. The technology is that video screen sharing and simulated clicking are carried out on the software layers of the first terminal and the second terminal, the support of the functionality of a software system of the terminals is needed, the technical difficulty is high, and for the vehicle diagnostic instrument, an operating system of the vehicle diagnostic instrument is usually closed, other software cannot be installed on the vehicle diagnostic instrument, namely screen sharing and simulated clicking on the software layers cannot be realized, so that the technology cannot be used for remote operation.
