Step S806, executing control commands in sequence

A preferred embodiment of the present invention also provides a system interaction method embodiment. FIG. 9 is a flowchart of a remote control terminal according to a preferred embodiment of the present invention. As shown in FIG. 9, the steps include:

Step S901: Receive an access request sent by the control terminal, where the request is from a terminal in the same Wireless-Fldelity (WiFi) environment as the controlled terminal, and the connection manner includes but is not limited to WiFi direct connection, and WiFi sharing (WiFi-tethering) connection and WiFi access

Step S902, after receiving the request, the controlled terminal requests to obtain the MAC address of the control terminal.

Step S903, receiving a MAC address fed back by the control terminal

Step S904, determining whether the MAC address is a trusted MAC address, and the trusted MAC address is manually set by the user, that is, storing a list of trusted MAC addresses in the controlled terminal, and confirming the control terminal MAC by comparing with the trusted MAC address list. Whether the address is a trusted MAC address

Step S905, if it is a non-trusted MAC address, rejecting the request, and feeding back to the terminal, the MAC address is an untrusted MAC address.

Step S906, determining whether it is an accessed IP (a fixed IP is assigned to the accessed MAC address, the flag is always 1 if the IP is in the connected state, and the flag is 0 if it is disconnected)

Step S907: If the IP is accessed to the control terminal, the IP address is the accessed IP address.

Step S908, if the IP is already accessed, the sent request instruction is destroyed (since the current product implementation scheme is that even if the request is the same IP address, and the current IP address is already connected to the controlled terminal, the instruction can be accepted, and the instruction is not accepted. Displayed on the controlled terminal, but after disconnecting, it will continue to receive the request information sent before, which is not easy to operate, and also causes trouble to the user. Consider the second instruction request to destroy the connected IP address)

Step S909, if it is not already connected to the IP, it is determined whether it is the first connection.

Step S910, if it is the first connection, send a flag bit to the control terminal, and the flag bit is sent through the wifi. Because of the 902.11 frame, the Type field of the MAC header, the Subtype value of the control frame 0000 to 1001 is Reserved, and currently If used, the control terminal may be randomly marked with a field that is not used, and the control terminal is required to record the flag bit. At the same time, the mark bit position is recorded in the IP access storage area. For example, a MAC address has been whitelisted and judged to be the first access. The controlled terminal allocates 0101 as the MAC address/IP address tag and records the corresponding tag bit.

Step S911, if the non-first access has accessed the IP, the request is received, and the verification control device sends the fixed by wifi. Mark the bit to determine if the mark is correct

Step S912, if the flag bit is empty, or the flag bit is incorrect, the request is rejected, and the control terminal feeds back, the MAC address is a clone MAC address, and the access is not allowed.

Step S913, if the flag bit is correct, the IP address is stored in the receiving IP address storage area.

Step S914, the IP access flag bit of the accessed control terminal is set to 1

Through the above steps, the user uses the projection device at home. In the related art, after the access mode of the projection device is IP access, only the IP is disconnected before the other IP can be accessed, the operation is not convenient, and the multi-person cannot be used. A preferred embodiment of the invention, after a user accesses the projection device through IP, does not affect another user accessing the projection device for remote control thereof, and can set a trusted MAC address and only the projection device. Receiving the settings received by the first request access command can also meet the requirements of security prevention and control.
