Remote control system and method based on short messages

Abstract

The invention relates to a remote control method and a remote control system based on short messages. The system comprises a remote control management center, a controlling terminal, a controlled terminal and an operator short message gateway. The method comprises the following steps: 1, the remote control management center is provided, and prestores authentication information; 2, the remote control management center receives a control request sent by the controlling terminal, compares the control request with the prestored authentication information for authentication, generates a control instruction and sends the control instruction to the controlled terminal through the operator short message gateway in a short message mode; and 3, if the controlled terminal judges that the control instruction is sent by the remote control management center according to a short message sending number, the controlled terminal executes corresponding action. The method and the system have the advantages of adopting a new remote control management system to process operation such as remotely controlled authentication and the like, improving the security and flexibility of remote control, reducing operating difficulty for users, reducing production difficulty of the controlled terminal, and contributing to batch production.

Description

technical field [0001] The invention relates to a remote control system and method, in particular to a short message-based remote control system and method. Background technique [0002] At present, the method for the mobile terminal to remotely control the controlled terminal mainly includes the following steps: first, the mobile terminal sends a control command to the controlled terminal in the form of a short message or audio, and then, after the controlled terminal receives the control command, the controlled terminal The control command is analyzed and compared, and when the control command is consistent with the control command data stored in the terminal, the controlled terminal performs corresponding operations. [0003] In the current remote control method for mobile terminals, control commands are generally transmitted to the remote controlled terminal, and the command interpretation part of the operating system of the controlled terminal receives and processes the...

Problems solved by technology

First of all, at present, it is necessary to save the information of the controller on the controlled terminal and perform remote control authentication operations to ensure that the remote control will not be used by other unauthorized users, but it is not easy to realize all the authentication information stored by the controlled terminal: because 1) , When the authentication management information is complex, such as when the controlled terminal has multiple authorized users, the authentication information needs to include each authorized user and its corresponding authority, the authentication operation will be very complicated, and the terminal needs to have relatively strong logic Judgment ability improves the cost of the controlled terminal; 2) Since the authentication information is stored in the controlled terminal, when the authorized user changes, the authentication information needs to be updated in the controlled terminal, and the terminals are distributed in various places or installed in different places. Easy to disassemble, not easy to update; 3) Since the authorized users and permissions of each controlled terminal are different, the authentication information is different, and the authentication information is stored in the controlled terminal, which is not convenient for mass production of terminals
