Description

Remote control device and remote control method thereof

Technical field

The present invention relates to a remote control device, and more particularly to a remote control device having a handheld control terminal and a remote control method of such a remote control device. The present invention is based on a Chinese patent application filed on Aug. 26, 2010, the application number of which is incorporated herein by reference.

Background technique

In daily life, people widely use remote control devices to control various devices, such as using a TV remote control to switch channels and volume of the TV, using the air conditioner remote control to adjust the temperature of the air conditioner, mode replacement, and using the car remote control to the car. Unlock and lock control.

Referring to FIG. 1, the existing remote control device is composed of a control terminal 1 and a controlled terminal 2, which is often a handheld remote controller having an input module 11 and a transmission module 12. The input module 11 is usually a button, a keyboard, etc., and the user inputs a signal through the input module 11, such as unlocking a car, switching a TV channel, etc., after the transmission module 12 receives the signal of the input module 11, the control signal of the input module 11 is wired or wirelessly. Transfer to the controlled terminal 2.

The controlled terminal 2 is generally fixedly mounted on a controlled device, such as a car, a television, an air conditioner, having a receiving module 21 and an executing module 22. The receiving module 21 is configured to receive the control signal from the control terminal 1 transmission module 12 in a wired or wireless manner and transmit the control signal to the execution module 22. The execution module 22 performs corresponding operations based on the received control signals, such as locking the door lock of the car, switching the television channel, and the like.

technical problem

However, the existing remote control device control terminal 1 only mechanically transmits a control signal according to the user's operation, and regardless of the current state of the controlled terminal 2, the control terminal 1 continuously transmits the same control signal according to the user operation. For example, the user has locked the car door lock, but if the user continues to press the lock button of the control terminal 1, the control terminal 1 continues to transmit the lock signal to the controlled terminal 2, resulting in waste of electric energy and even affecting the control terminal 1 The service life.

In addition, after the user transmits the control signal through the control terminal 1, the state of the controlled device cannot be known except that the controlled device is directly observed. For example, after the user locks the car door lock, the current state of the car door lock cannot be known except when the car is locked near the car to observe the car door lock or when the car door lock is locked. At the same time, after the user control terminal 1 transmits the control signal, it is often impossible to know whether the control signal is successfully executed.

Moreover, the user sometimes mistakenly presses the button on the control terminal 1, causing the control terminal 1 to improperly transmit the control signal, and the user often cannot know the current state of the controlled terminal, and cannot judge that the control terminal 1 erroneously transmits the control signal, Conducive to the use and work of the controlled equipment.

Technical solution

It is a primary object of the present invention to provide a remote control device that reduces wastage of electrical energy.

Another object of the present invention is to provide a remote control remote control method that avoids the same repeated transmission of the same control signal.

It is still another object of the present invention to provide a remote control method for a remote control device that facilitates the user to know the current state of the controlled terminal.

In order to achieve the above main object, the remote control device provided by the present invention comprises a control end and a controlled end, the control end has an input module and a transmission module, and the controlled end has a receiving module that receives a control signal of the control terminal transmission module and is controlled according to the receiving module. An execution module of the signal performing operation, wherein the controlled terminal further has a transmission module that receives a signal of the current state of the controlled terminal including the execution result of the execution module, and the control terminal further has a receiving module that receives the signal transmitted by the transmission module of the controlled terminal and a user interface module that memorizes the current state of the control terminal, the user interface module is connected to the receiving module and receives the signal transmitted by the receiving module, and does not transmit when determining that the state indicated by the input signal of the input module is consistent with the current state of the controlled terminal The module transmits control signals.

In a preferred solution, the control terminal is further provided with an output module connected to the user interface module.

In order to achieve the above other object, the present invention provides a remote control method for the above remote control device, comprising: after receiving a signal of the input module, the user interface module transmits a control signal to the receiving module of the controlled terminal through the transmission module, and the receiving module of the control terminal receives the control signal. After being sent to the execution module, the execution module transmits a signal including the current state of the controlled end of the execution result to the receiving module of the control terminal through the transmission module, and the receiving module transmits a signal including the current state of the controlled end of the execution result to the receiving module. The user interface module, the user interface module memorizes the current state of the controlled terminal, and after receiving the signal of the input module again, the user interface module determines whether the current state of the controlled terminal is consistent with the state indicated by the received signal, and if they are consistent, the transmission does not pass the transmission. The module transmits control signals.

A preferred solution is that the control terminal further has a clock module connected to the user interface module. The clock module stores a time threshold. After the user interface module transmits the control signal through the transmission module, it is determined whether the successful execution is included in the time threshold.

Embodiments of the invention

Referring to Figure 2, Figure 2 is a block diagram showing the structure of an embodiment of the remote control device of the present invention. The embodiment is composed of a control terminal 3 and a controlled terminal 4, and the control terminal 3 is a hand-held remote controller for issuing a control signal, and is installed in a controlled device, such as a car, for receiving and executing control. signal.

The control terminal 3 has a user interface module 31, a transmission module 32, a receiving module 33, a clock module 34, an input module 35, and an output module 36.

The input module 35 is a contact interface for a user input signal such as a button or a keyboard, and inputs a signal to the user interface module 31. The user interface module 31 receives the signal transmitted by the input module 35, and generates a corresponding control signal to the transmission module 32 according to the signal, and the control module transmits the control signal to the controlled terminal 4. The receiving module 33 is configured to receive the signal transmitted by the control terminal 4 and transmit the received signal to the user interface module 31.

A time threshold is stored in the clock module 34, and the clock module 34 can begin or terminate timing under the control of the user interface module 31. When the user interface module 31 transmits a control signal to the transmission module 32, the clock module 34 is started to time. After the clock module 34 counts to the time threshold, a signal is transmitted to the user interface module 31 to notify the user that the interface module 31 has finished counting the time. Of course, the user interface module 31 can also transmit a signal to stop the timing of the clock module 34, and the clock module 34 stops the timing after receiving the signal.

In this embodiment, the user interface module 31 is further configured to memorize the current state of the controlled terminal 4, and the current state of the controlled terminal 4 may be a locked state or an unlocked state. Moreover, when the user interface module 31 receives a new signal from the input module 35, it will determine whether the state indicated by the new signal is consistent with the current state of the controlled terminal 4, and if it is consistent, the relevant control will not be transmitted through the transmission module 32. signal.

The output module 36 is a display light (such as an LED light) or a buzzer or a display screen, etc., and is used to indicate the current state of the controlled end. Of course, the output module 36 should have a variety of different states to indicate the current state of the controlled end, for example, when the car door lock is locked, the display light is green, the red color is displayed when the lock is unlocked, or the flashing is represented by using different time lengths. The current state of the console. If the output module 36 is a buzzer, the two states of different frequencies or two segments of sound having different playing time lengths may be used to indicate the current state of the controlled terminal. If the output module 36 is a display screen, the text or image may be directly used. Indicates the current state of the controlled terminal.

The controlled terminal 4 is provided with an execution module 41, a transmission module 42, and a receiving module 43. The receiving module 43 receives the control signal transmitted by the control terminal 3 transmission module 32, and transmits the received control signal to the execution module 41.

The execution module 41 performs a corresponding operation according to the received control signal, such as locking the door lock of the automobile, and transmits a signal including the current state of the controlled terminal 4 including the execution result to the transmission module 42, and the transmission module 42 will include the execution result. The signal of the current state of the control terminal 4 is transmitted to the receiving module 33 of the control terminal 3.

In this embodiment, the transmission module 32, the receiving module 33 of the control terminal 3, and the transmission module 42 and the receiving module 43 of the controlled terminal 4 all use the wireless transmission mode for signal transmission, and the actual transmission can also use the wired transmission mode to the signal. Transfer.

In the embodiment, the transmission module 32 of the control terminal 3 and the transmission module 42 of the control terminal 4 encrypt the transmitted signal, and the receiving module 33 of the control terminal 3 and the receiving module 43 of the controlled terminal 4 receive the signal. The incoming signal is decrypted accordingly to ensure the security of the signal transmission.

Of course, only the signal transmitted by the transmission module 32 of the control terminal 3 may be subjected to encryption processing. Correspondingly, the receiving module 43 of the control terminal 4 performs corresponding decryption processing on the received signal. Conversely, only the signal transmitted by the transmission module 42 of the control terminal 4 may be subjected to encryption processing. Correspondingly, the receiving module 33 of the control terminal 3 performs corresponding decryption processing on the received signal.

The workflow of the remote control device of this embodiment will be described below with reference to FIG.

The user transmits the control signal using the remote control device, first inputting the signal using the input module, such as pressing a button or a keyboard, and inputting the operation to be performed, such as locking the door lock of the automobile. At this time, the input module transmits a signal to the user interface module, and the user interface module performs step S1 to receive the signal transmitted by the input module.

After receiving the signal, the user interface module performs step S2 to determine whether the state indicated by the signal received from the input module is consistent with the current state of the controlled terminal. If not, the process proceeds to step S3. If the process is consistent, the process ends. Waiting to receive the next signal from the input module, the control signal will not be transmitted through the transmission module.

Of course, if the control terminal is in the initial state, for example, after receiving the signal from the input module for the first time after the power-on reset, step S2 may be performed without condition, and step S3 is performed unconditionally. After receiving the signal from the input module a second time, step S2 is performed.

In step S3, the user interface module generates a control signal according to the signal received from the input module, and transmits the control signal to the controlled terminal through the transmission module, and the control signal is a control signal subjected to encryption processing. At the same time, the user interface module transmits a signal to start timing to the clock module. After receiving the signal, the clock module starts timing and transmits a signal to the user interface module after the timing time ends, that is, after the timing of the time threshold is terminated.

Then, the controlled terminal performs step S4, and the receiving module receives the control signal from the control end. Since the control signal is an encrypted control signal, the receiving module needs to decrypt the control signal after receiving the control signal, and transmits the decrypted control signal to the execution module, and the execution module performs a corresponding operation, such as locking the automobile. Door lock. After the execution module performs the corresponding operation, the transmission module of the controlled terminal transmits a signal including the current state of the controlled terminal that successfully outputs the result of the control signal, and the transmission module transmits the signal to the receiving module of the control terminal. Of course, the transmission module also encrypts the signals that need to be transmitted before transmitting.

The receiving module of the control terminal performs the decryption process after receiving the signal, and transmits the decrypted signal to the user interface module. The user interface module performs step S5 to determine whether the successful execution control is received from the controlled terminal within the time threshold of the clock module timing. The signal of the result of the signal is the signal of the current state of the controlled end. If yes, step S7 is performed, otherwise step S6 is performed.

In step S7, since the control signal is successfully executed, the user interface module memorizes the current state of the controlled terminal, and outputs the current state of the controlled terminal through the output module. At the same time, the user interface module transmits a signal to stop the timing of the clock module, and the clock module also stops timing.

If the user interface module finishes receiving the signal transmitted by the clock module after receiving the relevant signal transmitted by the clock module, and still does not receive the signal from the controlled terminal transmitted by the receiving module, indicating that the control signal is not successfully executed, the user interface module executes Step S6. The user interface module also remembers the state of the currently controlled terminal and outputs a signal that the control signal has not been successfully executed through the output module. Then, returning to step S3, the user interface module transmits the control signal again through the transmission module of the control terminal until receiving the signal of the current state of the controlled terminal including the result of the successful execution or receiving other signals input by the user.

It can be seen from the above scheme that if the user has transmitted the control signal once and is successfully executed, the user interface module will judge that the state indicated by the signal transmitted by the user is the same as the current state of the controlled terminal, and will not be transmitted the next time the same control signal is transmitted. The control signal is transmitted again to reduce the power consumed by the control terminal, which is beneficial to prolonging the service life of the control terminal and the remote control device.

Moreover, regardless of whether the control signal is successfully executed, the control terminal outputs a prompt signal through the output module, and the user can understand the state of the controlled terminal without directly observing the controlled device, and timely know whether the control signal is successfully executed. Once the user presses the button incorrectly, the user can also know by observing the prompt signal of the control terminal output module to ensure that the controlled device is in the correct state.

Of course, the foregoing embodiment is only a preferred embodiment of the present invention, and there may be more changes in actual application, for example, when the signal confidentiality required between the control terminal and the controlled terminal is not high, the control terminal The signal transmitted with the controlled terminal is not subjected to encryption processing; or, the prompt signal or the like is not output when the signal of the current state of the controlled terminal including the result of successfully executing the control signal is not received, and these changes can also achieve the object of the present invention.

Finally, it should be emphasized that minor changes such as changes in the length of the time threshold stored by the clock module, changes in the manner of signal transmission between the control terminal and the controlled terminal are also included in the scope of protection of the claims of the present invention.
