Remote controller identification method and remote controller identification device

Abstract

The invention discloses a remote controller identification method and a remote controller identification device. The remote controller identification method comprises the following steps: a main controller of equipment sends a binding random number; the remote controller receives and stores the binding random number; the main controller regularly sends verification random numbers and algorithm information to the remote controller; the remote controller receives the verification random number and the algorithm information and calculates according to the verification random number and the algorithm information to obtain a feedback result; and the main controller compares the feedback result with a standard result in the main controller, if the feedback result is consistent with the standard result, the identity of the remote controller is legal, otherwise, the identity of the remote controller is illegal. According to the remote controller identification method and the remote controller identification device, the binding random number is sent to the remote controller through the main controller, and verification is carried out through the verification random number and the algorithm information in subsequent identity identification, so on one hand, construction of an integral system of parts produced by different manufacturers can be realized; on the other hand, other people are prevented from cracking the identity recognition method by means of monitoring and the like, and the safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of remote control devices, in particular to a remote control identification method and a remote control identification device. Background technique [0002] With the development of science and technology, various modern machinery and equipment are generally controlled by remote controllers to improve the convenience of control. In order to ensure the safety of the device, it is usually necessary to pair the remote controller with the device, so that only one remote controller can control a corresponding device. At present, a fixed key is generally stored in the remote control and the controller of the device. When in use, the controller of the device judges whether the key in the remote control is correct. If it is correct, the remote control is considered a legal remote control and other control operations. However, this method is easy to be cracked by illegal devices and has low security. Moreover, in m...

However, this method is easy to be cracked by illegal devices, and the security is low

Moreover, in modern equipment, multiple manufacturers often develop different components and then build an overall system. At this time, the components are independent of each other. For example, there is no connection between the remote control and the device, and it is difficult to pre-exist the key. remote control
