[0034] Among them, during the verification and analysis of the key receiving module, it is analyzed whether the dynamic key group input by the remote control end is a key group;
[0035] The key authentication unit includes a key authentication module for authenticating a key, the key authentication module is electrically connected to a feedback module for feedback information and an analysis module for analyzing a signal source, the analysis module is electrically connected to a verification module for verifying whether the remote control terminal is authenticated, the verification module is electrically connected to the remote control terminal, the analysis module is electrically connected to the feedback module, the feedback module is electrically connected to the remote control terminal, the verification module is electrically connected to a control module for controlling the controlled terminal and a reset module for resetting the key, and the control module is electrically connected to a storage module for data storage;
[0036] The key authentication module receives the dynamic key group input by the remote control end, and analyzes the dynamic key group to determine whether the dynamic key group is correct. When the key authentication module analyzes that the dynamic key group is incorrect, the feedback module generates error information and feeds it back to the remote control end. When the key authentication module analyzes that the dynamic key group is correct, the analysis module analyzes and authenticates whether there are multiple remote control end signal sources applying for authentication in the dynamic key group.
[0037] Through the above embodiment, the key authentication module verifies whether the dynamic key group is correct, thereby accurately connecting the remote control end and the controlled end, and the feedback module can timely feedback the remote control end dynamic key input error, so that the remote control end can re-enter the dynamic key group in time;
[0038] When the analysis module analyzes that there are multiple remote control signal sources applying for authentication, the analysis module will generate a dynamic 30s valid digital group, and generate a verification instruction to be fed back to the remote control by the feedback module. The remote control obtains the dynamic digital group and inputs the dynamic digital group.

[0040] The verification module verifies the digital group. When the digital group is successfully verified, the control module establishes a control connection with the remote control terminal. When the digital group fails to be verified, the reset module resets the key. The control module controls the operation and the key data is stored in the storage module to create a work log.
[0041] Through the above embodiment, the digital group is verified by the verification module. When the digital group is successfully verified, the control module establishes a control connection with the remote control end so that the remote control end can control the controlled end. When the digital group verification fails, the key is reset by the reset module. The control module controls the operation and the key data is made into a work log and stored by the storage module, which can more accurately record the control situation of the remote control end. At the same time, the storage module can enable the remote control end that has established the connection to be directly controlled by the control end.

After the key authorization module grants the remote control terminal the control right, the dynamic key module generates a dynamic key group;
[0047] 2) The dynamic key module generates a dynamic key group. The key management module receives the dynamic key group and sets a 60s validity period. The remote control terminal obtains the dynamic key group by checking the controlled terminal. The key authorization module authorizes the key validity period to the key receiving module. The remote control terminal inputs the digital key group and the key receiving module receives it.
[0048] 3) When the key receiving module receives the dynamic key group for more than 50-60s, the key receiving module will feedback to the remote control end that the dynamic key group is invalid, and feedback to the dynamic key module to generate a new dynamic key group and transmit it to the key management module. When the key receiving module receives the dynamic key group for less than 60s, it will enter the key authentication mode.
[0049] In step S2:
[0050] 1) When the key authentication module analyzes that the dynamic key group is incorrect, the feedback module generates error information and feeds it back to the remote control end. When the key authentication module analyzes that the dynamic key group is correct, the analysis module analyzes and authenticates whether there are multiple remote control end signal sources applying for authentication in the dynamic key group;
[0051] 2) When the analysis module analyzes that there are multiple remote control signal sources applying for authentication, the analysis module will generate a dynamic 30s valid state digital group, and generate a verification instruction to be fed back to the remote control by the feedback module. The remote control obtains the dynamic digital group by checking the controlled end, and inputs the dynamic digital group for verification. When the analysis module analyzes that there is only a single remote control signal source applying for authentication, the analysis module will generate a single control digital group, and generate a verification instruction to be fed back to the remote control by the feedback module. The remote control obtains the single control digital group by checking the controlled end for verification;
[0052] 3) When the verification module successfully verifies the digital group, the remote control end controls the controlled end through the control module. When the digital group verification fails, the reset module resets the dynamic key group, and the remote control end needs to re-enter a new dynamic key group.

When the key authentication module analyzes that the dynamic key group is correct, the analysis module analyzes whether there are multiple remote control signal sources applying for authentication in the authentication dynamic key group. When the analysis module analyzes that there are multiple remote control signal sources applying for authentication, the analysis module will generate a dynamic 30s valid state digital group, and generate a verification instruction to be fed back to the remote control end by the feedback module. The remote control end obtains the dynamic digital group by checking the controlled end, and inputs the dynamic digital group for verification. When the analysis module analyzes that only a single remote control signal source applies for authentication, the analysis module will generate a dynamic single control digital group, and generate a verification instruction to be fed back to the remote control end by the feedback module. The remote control end obtains the single control digital group by checking the controlled end for verification. When the verification module verifies the digital group successfully, the remote control end controls the controlled end through the control module. When the digital group verification fails, the reset module resets the dynamic key group, and the remote control end needs to re-enter a new dynamic key group. At the same time, the remote control end controls the operation steps and key data through the control module, and the storage module creates a work log and stores it.
