Description

Technical Field

[0001] The present invention relates to the technical field of remote control replication, and more specifically, to an infrared remote control anti-replication method and device. Background Art

[0002] Infrared remote controls have the advantages of simple design, low price, convenient use, low power consumption, etc., and have been widely used. Although subsequent remote controls based on wireless communication principles such as Bluetooth have more functions and better privacy, they cannot completely replace infrared remote controls due to higher costs, more complex design and usage methods.

[0003] Infrared remote controls usually use infrared signals modulated at a fixed frequency. They only need to transmit control signal infrared codes and do not need to receive and feedback signals, so they are very easy to be replicated. Replication scenarios are as Figure 1 shown.

[0004] Learning infrared remote controls support receiving and replicating the code signals of prototype remote controls. After replicating the code signals and associating them with the buttons to complete learning, the replicated code signals can then be triggered by pressing the buttons to be transmitted.

[0005] Smartphones usually also have infrared code transmission functions or support external infrared signal transmitters for code transmission. After installing application programs such as "universal remote control" on the mobile phone, according to the characteristic data of the code values of various infrared remote controls stored in the program, it can simulate the code transmission of multiple infrared remote controls and replace the infrared remote control for use.

[0006] In many cases, remote control product suppliers do not want the infrared remote controls they design and produce to be replicated. So they change the design and production to remote controls using wireless communication principles such as Bluetooth. However, such design changes will make the system more complex, increase costs, and the user experience is not as simple and convenient as the original infrared remote control.

[0007] Therefore, the easy replication of remote controls will lead to the following problems:

[0008] 1. It is easy to be used by unauthorized users. Equipment such as televisions and air conditioners in public places usually do not want to be remotely controlled by any user.

[0009] 2. It severely limits the market price of the remote controls originally designed and produced by the factory. This causes some infrared remote controls with novel structural designs and high-quality materials to not be able to fetch a good price because customers have more low-cost options - they can easily replace the remote control function of the original factory remote control with a universal remote control with ordinary materials and low price, or replace the remote control function with the remote control function of the mobile phone.

It should be understood that those skilled in the art can recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid unnecessary details from obscuring the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0053] See Figure 2 , Figure 2It is a flowchart of an infrared remote control anti-copying method provided by an embodiment of the present invention. The infrared remote control anti-copying method includes steps S1 - S4:

[0054] S1. Monitor the pressing event of the start key of the infrared remote control, generate a start code and a first feature code according to the duration of the start key pressing event, and send the start code and the first feature code to the receiving remote control. Step S1 includes steps S11 - S12:

[0055] S11. When it is detected that the start key of the infrared remote control is pressed, generate a first start code and send the first start code to the receiving remote control in real time.

[0056] In this embodiment, referring to Figure 3 , Figure 3 It is a structural schematic diagram of an infrared remote control provided by an embodiment of the present invention. When using the remote control to control the device, it is necessary to first send a power-on signal with this remote control. During this process, an address feature code is generated, and the continuous effective time of the address feature code is the current power-on time and becomes invalid after shutdown. Therefore, it is necessary to send codes twice when the infrared remote control starts, namely the first start code and the second start code, and the time interval between the two code sendings corresponds to the address feature code according to the corresponding rules.

[0057] S12. When it is detected that the start key of the infrared remote control is released, generate a second start code, use the generation interval between the first start code and the second start code as a variable factor, generate a first feature code according to the first start code, the second start code and the variable factor, and send the first feature code and the second start code to the receiving remote control in real time.

[0058] In this embodiment, the time interval between the user pressing the enable key and releasing the start key is used as the variable factor of the feature code. Because this time will vary due to human operation fluctuations, the address feature code generated each time will be different. When the key delay time is short, some additional delay needs to be added to make the delay time long enough and the start code sending time span long enough so that the signal is more difficult to copy. The generation of the feature code value corresponds to multiple interval code sendings during startup. The code sending interval time is much longer than the time interval of a single infrared code sending signal, increasing the difficulty of signal copying. After each power-on startup, the code sending feature value changes. It can be set that when the feature code generated this time is the same as the feature value code generated last time, it is invalid, further improving the copying difficulty.

[0059] S2. Generate a second feature code in the receiving remote control according to the start code, compare the first feature code and the second feature code, and determine whether to monitor the pressing event of the command key of the infrared remote control according to the comparison result. Step S2 includes steps S21 - S22:

[0060] S21. In the receiving remote controller, using the generation interval between the first start code and the second start code as a variable factor, generate a second feature code based on the first start code, the second start code, and the variable factor.

[0061] In this embodiment, refer to Figure 4 , Figure 4 which is the structural schematic diagram of the receiving remote controller provided by an embodiment of the present invention. The timer frequency of the receiver is consistent with the counter frequency of the remote controller, and the address feature code is calculated through the time interval between receiving the start code 1 and the start code 2.

[0062] S22. Compare the first feature code and the second feature code. If the comparison is successful, monitor the instruction key pressing event of the infrared remote controller. If the comparison is unsuccessful, determine that the startup fails.

[0063] In this embodiment, refer to Figure 5 , Figure 5 which is the process diagram of a method for preventing infrared remote controller replication provided by an embodiment of the present invention. Compare the calculated address feature code with the received address feature code. If they are the same (equal or differ by plus or minus 1), confirm that the new feature code is valid; otherwise, it is invalid. To further increase the difficulty of signal replication, it can be designed that the address feature code for each startup must be different from the previous startup.

[0064] S3. Monitor the instruction key pressing event of the infrared remote controller, generate an instruction code based on the instruction key pressing event, and send the instruction code and the first feature code to the receiving remote controller; Step S3 includes steps S31 - S32:

[0065] S31. If it is monitored that there is an instruction key pressing event of the infrared remote controller, generate an instruction code corresponding to the instruction key pressing event.

[0066] S32. Send the instruction code and the first feature code to the receiving remote controller in real time.

[0067] S4. In the receiving remote controller, compare the first feature code and the second feature code, and determine whether to execute the instruction indicated by the instruction code according to the comparison result. Among them, in the receiving remote controller, compare the first feature code and the second feature code. If the comparison is successful, execute the instruction indicated by the instruction code. If the comparison is unsuccessful, discard the instruction code.

[0068] In this embodiment, when sending other signal codes except the startup signal, the address feature code needs to be added, and the address feature code needs to be compared. The signal is valid only when the address feature codes are the same; otherwise, it is invalid.

[0069] In summary, the "feature code" is generated when the infrared remote control sends a start signal and becomes invalid after shutdown. When starting up, the "infrared remote control" sends the start code twice at a certain time interval according to the duration of the operator pressing the start button, and the generation of the "feature code" corresponds to the duration interval of the two code transmissions. The "receiving remote control" generates the same "feature code" according to the duration interval of the two received start codes using the same rule as the "infrared remote control". After startup, the code value of each code transmission by the "infrared remote control" needs to append the "feature code", and the receiving remote control needs to compare the "feature code" every time it receives a signal. The "feature code" remains valid after this startup until shutdown. In principle, the feature of the "feature code" is transmitted from the "infrared remote control" to the "receiving remote control" through the time interval delay between the two start code transmissions during startup, rather than the usual method of transmitting the feature value through the code value, which prevents the "feature code" from being copied by replicating the code value. During the startup process, the "infrared remote control" transmits the "feature code" to the "receiving remote control" through the time delay feature of the two start signal code transmissions. The "infrared remote control" needs to append the "feature code" to subsequent code transmissions. After startup, the "receiving remote control" needs to compare whether the "feature code" is correct every time it receives a signal.

[0070] To prevent the infrared code transmission signal from being copied, the infrared remote control design of this design has the following features:

[0071] 1. The appended feature code for code transmission changes every time after startup, and the receiving end and the sending end can synchronously change the appended feature code.

[0072] 2. The valid range of the appended feature code for code transmission is this startup. The feature code value is generated during startup, and the device can only start up after determining that the feature code value is correct. The feature becomes invalid when shutting down or resetting.

[0073] 3. Multiple interval delay code transmissions are required during startup, and the delay time exceeds the learning duration (200 ms) of an ordinary learning remote control.

[0074] 4. The feature code value generated during this startup must be different from the feature code value of the previous startup, otherwise it is invalid and startup needs to be performed again.
