[0002] The communication method and working mode adopted by the remote control (IC card) photoelectric switch lock commonly used now are: the remote control (IC card) of the photoelectric switch lock (hereinafter referred to as the remote control (IC card)) to the executive device of the photoelectric switch lock ( Hereinafter referred to as the execution device) sends the operation command (password); the execution device confirms after receiving the operation command (password); if it is correct, it executes; if it is wrong, it refuses to execute; there are three unsafe factors in this working mode: 1. The same manufacturer If the passwords used in the same series of products are repeated, different remote controllers (IC cards) can control each other's photoelectric switch locks.
2. During the communication process between the remote control (IC card) and the executive device, it is possible to control the photoelectric switch lock by using a digital information collection device to collect communication information and copy the remote control (IC card).
3. Use a decoder to decode the photoelectric switch lock, and it is also possible to control the photoelectric switch lock

Embodiment 1
[0020] Such as figure 1 As shown, the present invention provides a communication method for an anti-decoding photoelectric switch lock, comprising the following steps:
[0021] S100), the remote controller (IC card) sends the identification code to the execution device;
[0022] S200), after the execution device performs identification and confirmation, automatically activate the transponder corresponding to the remote control (IC card) in the execution device, and send an instruction to start "send operation command (password)" to the remote control (IC card) ;
[0023] S300), the remote controller (IC card) sends an operation instruction to the execution device after receiving the instruction confirmation;
[0024] S400), the execution device executes the operation according to the instruction after receiving the confirmation of the instruction, and sends the code group sequence guide code used for the next operation and the operation completion instruction to the remote c...
Embodiment 2
[0028] Such as figure 2 As shown, different from the above embodiment, the step S500) is: after the remote controller (IC card) receives the instruction confirmation, it determines the code used for the next operation according to the specific position given by the code group sequence guide code Group sequence, and delete all code group sequences used in this operation at the same time as the execution device, and end this operation.
[0029] As can be seen from the above, the present invention has the following beneficial technical effects:
[0030] 1. The present invention uses non-repetitive random sequence as a password, there is no logical relationship between the sequence, and the exhaustion resistance of the random sequence is 10 26 The above order of magnitude ensures that the password will not be repeated;
[0031] 2. In the present invention, the use of the password is a one-time non-reuse, and it will be deleted immediately after use to prevent the risk of decodi...

Abstract
The invention relates to a communication method for an anti-decoding photoelectric switch lock, comprising the following steps: S100) a remote controller sends an identification code to an execution device; S200) after the execution device performs identification and confirmation, automatically activates the execution device corresponding to the remote control corresponding transponder, and send an instruction to start "send operation instruction" to the remote controller; S300) the remote controller sends the operation instruction to the execution device after receiving the confirmation of the instruction; S400) the execution device executes the operation according to the instruction after receiving the confirmation of the instruction, and Send the code group sequence guide code used for the next operation and the operation completion instruction to the remote controller; S500) After receiving the instruction confirmation, the remote controller determines the code group used for the next operation according to the specific position given by the code group sequence guide code sequence and end the operation. The present invention effectively prevents decoding by means of instant communication between the execution device and the remote controller to obtain the instantly generated password.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a communication method for an anti-decoding photoelectric switch lock.
