Learning remote control system

The present invention relates to a learning remote control system, and more particularly to a learning remote control system that samples a remote control signal for learning storage.

With the advancement of the times, the electrical products used in daily life of human beings (hereinafter referred to as electrical appliances) are increasing day by day. All TVs, radios, air conditioners, electric cookers, ovens and various multimedia devices are inseparable from the lives of modern people. Switch-controlled home appliances or lighting equipment, electrical appliances have become an indispensable necessity for people's livelihood in contemporary society. However, if a wide variety of appliances are controlled by different remote controls, it will inevitably lead to complicated management.

In view of this, many universal remote control products are currently available on the market. The main principle is to build remote control codes for multiple sets of electrical appliances in the remote control, so as to integrate the remote control functions of several electrical appliances into the same remote control. However, with the built-in remote control code, once users purchase new electrical appliances, they will face difficulties in expanding their support for new electrical appliances, resulting in poor user convenience. Therefore, the market response of the commercially available universal remote control is not as good as expected.

In order to solve the above problem, please refer to FIG. 1 , the Republic of China Announcement No. M427736 discloses a conventional electric appliance integrated control system 9 which utilizes more than one signal transmitting/receiving device 91, each including a search locking unit 911, the signal The transmitting/receiving device 91 can be respectively disposed in different floors or compartments, and the search locking unit 911 is used to search for and lock the infrared frequency for remotely controlling the respective appliances 92 and memorize the storage, so whenever additional support for new appliances is required, It is only necessary for the search lock unit 911 to re-search and memorize the infrared frequency of the new appliance. Thereby, it is selected by a control processing unit 93 according to the appliance 92 to be controlled. Selecting the specific infrared frequency, the control processing unit controls the signal transmitting/receiving device 91 to emit the specific infrared frequency for manipulating the electrical device, achieving unified control by the control processing unit 93, and simplifying the remote control of the electrical product. efficacy.

However, the conventional appliance integrated control system 9 relies on the search for the locking unit 911 to search for and lock the infrared frequency for remotely controlling the respective appliances 92 in a frequency scanning manner. When the frequency scanning process is quite exhausted, the convenience of use is still not Very ideal. Furthermore, since the transmission methods used by various electrical appliances are not the same, especially in the ever-changing development of technology, the transmission methods used by electrical appliances have long since deviated from the scope of infrared transmission, and the signal formats used by various electrical appliances are also very different. The locking unit 911 can only support the conventional infrared transmission in which the signal format conforms to a specific specification by means of frequency scanning, and the application range is obviously insufficient.

In summary, the commercially available universal remote control and the conventional integrated control system 9 have disadvantages such as "poor convenience" and "small application range", and further improvements are needed to simplify the integration and control of the complexity of various electrical appliances. Enhance the coverage of the types of appliances that are applicable.

The above and other objects, features and advantages of the present invention will become more <RTIgt; Coupling means that the two devices can transfer data to each other by means of a wired entity, a wireless medium or a combination thereof (for example, a heterogeneous network), which is common in the technical field to which the present invention pertains. Knowledge people can understand.

Referring to FIG. 2 and FIG. 3, a system architecture diagram of a learning remote control system 1 according to a preferred embodiment of the present invention is coupled to a wireless transceiver module 12, a memory unit 13 and a communication module by a processing unit 11 respectively. Group 14.

The processing unit 11 is a conventional computing device, and is preferably a micro-controller unit (MCU). The wireless transceiver module 12 is coupled to the processing unit 11 for receiving one from the original remote controller of each electrical appliance A. Remotely controlling the signal and transmitting the remote control signal to the processing unit 11; the memory unit 13 is composed of a non-volatile memory (for example, a flash memory), a floppy disk or a hard disk, and the like, for processing Unit 11 receives and stores the remote control The communication module 14 is a communication interface, so that the processing unit 11 can be coupled to a controller R by wired or wireless transmission. The controller R can be a conventional remote controller, a control panel, a computer host, a mobile phone, or the like. A tablet or notebook computer or the like is operable by the user to control the processing unit 11.

In more detail, the wireless transceiver module 12 can include an infrared receiver, such that the processing unit 11 can transmit or receive infrared signals through the wireless transceiver module 12; or the wireless transceiver module 12 can also include an antenna (antenna) The processing unit 11 is capable of transmitting or receiving a radio frequency (RF) signal via the wireless transceiver module 12. Similarly, the communication module 14 can include a wired entity communication interface (eg, RS-485), so that the processing unit 11 can be coupled to the controller R by wired transmission; or the communication module 14 can include physical communication. The interface wireless device communication interface (for example, RN 171) enables the processing unit 11 to be coupled to the controller R by wireless transmission.

It is noted that, as shown in FIG. 4 , in the embodiment, the wireless transceiver module 12 includes a plurality of wireless transmitters 121 , and the plurality of wireless transmitters 121 can be electrically connected to a circuit board 122 . The wireless transmitters 121 are respectively disposed in different directions, so as to expand the coverage of the remote control signals transmitted by the wireless transceiver module 12. For example, when the processing unit 11 transmits or receives an infrared signal through the wireless transceiver module 12, the wireless transmitter 121 included in the wireless transceiver module 12 is an infrared emitter, which is a conventional infrared emitter (usually a The signal transmission angle of the infrared diode is about 60°, so the wireless transceiver module 12 preferably includes at least six wireless transmitters 121, as shown in FIG. 5, by placing six wireless transmitters 121 along one The circumferences are arranged in a radial manner, and the wireless transmitters 121 are separated by an angle of 60°, and the signal transmission angles of the six wireless transmitters 121 can completely cover the periphery of the wireless transceiver module 12; in other words, a plurality of wireless transmitters. When the circumference of the extension is radially arranged, any two adjacent wireless transmitters 121 can extend the coverage of the remote control signal emitted by the wireless transceiver module 12 by extending the circumference by less than 60°, thereby avoiding Signal transmission dead When the wireless transceiver module 12 is disposed in any space, the processing unit 11 can smoothly send a remote control signal to all electrical products in the space via the wireless transceiver module 12.

Referring to FIG. 6, a control flow chart of the learning remote control system 1 of the preferred embodiment of the present invention, the controller R can transmit a control command to the processing unit 11, for example, the controller R is a remote control. The user can press a button to generate the control command. Similarly, when the controller R is a mobile phone, the user can touch the touch panel to generate the control command. The processing unit 11 will receive the control command via the communication module 14 and determine the type of the control command accordingly. In detail, the processing unit 11 will determine whether the control command is a command to "take a remote control signal" or a command to "send a remote control signal". If it is determined that the control command is a command to retrieve the remote control signal, the processing unit 11 will receive the remote control signal sent by the original remote controller of the electric appliance A via the wireless transceiver module 12. Then, the processing unit 11 can set a sampling frequency F according to the type of the remote control signal, and sample the remote control signal at the sampling frequency F.

According to Nyquist's Theorem, the sampling frequency F must be greater than twice the carrier frequency of the remote control signal, and in practice the sampling frequency F is preferably greater than five to ten times the carrier frequency of the remote control signal. In other words, the carrier frequency of the infrared remote control signal is usually 38 kHz. Therefore, when the remote control signal is an infrared remote control signal, the processing unit 11 can set a sampling frequency F greater than 76 kHz to sample the remote control signal, and the sampling frequency is better. More than 190 kHz; similarly, when the remote control signal is a radio frequency remote control signal such as a Bluetooth signal, since the carrier of the Bluetooth signal is about 2.4 GHz, the processing unit 11 can set a sampling frequency F greater than 4.8 GHz to the blue The bud remote control signal is sampled, and the sampling frequency is preferably greater than 12 GHz.

The processing unit 11 stores the sampled remote control signal in the memory unit 13 after the sampling of the remote control signal is completed. The processing unit 11 preferably stores the sampling frequency F for sampling the remote control signal. Thereby, the learning remote control system 1 successfully learns the The remote control signal, for example, if the controller R is a remote controller, the remote control signal can correspond to one of the buttons; or, if the controller R is a mobile phone or a computer, the user can define the remote control signal by himself Representative function. By repeating the above steps, the learning remote control system 1 can completely learn all the remote control signals of the original remote controller of the electric appliance A, and all the remote control signals of the original remote controllers of the other electric appliances A.

In contrast, if the processing unit 11 receives a control command and determines that the control command is not a command to retrieve the remote control signal, it can determine that it is a command to send a remote control signal. The processing unit 11 selects the remote control signal to be sent by the control command from the memory unit 13, and reads the sampling frequency F used by the processing unit 11 to sample the remote control signal, so as to restore the remote control by using the sampling frequency F. The signal is transmitted through the wireless transceiver module 12 to control the associated appliance A.

With the above system, the memory unit 13 can store all the remote control signals of the original remote controllers of the respective appliances A, so that the user can use the controller R to issue control commands to the processing unit 12 via the communication module 14. In order to separately control each of the electrical appliances A, the purpose of integrating and controlling different electrical appliances is achieved.

It should be noted that the processing unit 11 can sample the remote control signals having different carrier frequencies by setting different sampling frequencies F, so that the learning remote control system 1 can improve the traditional infrared remote control signal as long as it can learn. The sampling frequency F can learn the remote control signals of new wireless transmission protocols such as WiFi, Bluetooth, Zigbee or Near Field Communication to support different signal transmission methods and signal formats. However, if the electrical device A to be integrated and controlled by the learning remote control system 1 uses the same transmission mode and signal format, the processing unit 11 can also adopt a single sampling frequency F to further simplify the system complexity and reduce the construction cost.

In summary, the preferred embodiment of the learning remote control system of the present invention samples a remote control signal through a wireless transceiver module at a sampling frequency through a processing unit, and samples the remote control signal. The result is stored in a memory unit. Compared with the conventional universal remote control, the built-in remote control code has the disadvantage that it is difficult to expand and support the new electrical appliance. The learning remote control system can easily learn the remote control signal of the new electrical appliance. Furthermore, the present invention The learning remote control system directly stores the memory-sampled remote control signal, and does not demodulate the remote control signal, so the speed of learning the remote control signal is faster, and the frequency is scanned by the conventional integrated control system 9 The infrared frequency used to remotely control each appliance is locked, and the efficiency of learning the remote control signal using the learning remote control system will be greatly improved. Accordingly, the learning remote control system of the present invention does have the effect of improving ease of use.

Furthermore, in the preferred embodiment of the learning remote control system of the present invention, the carrier frequency of the remote control signal is directly sampled by using the sampling frequency, so that the remote control signal using different signal transmission modes and signal formats can be separately learned by changing the sampling frequency. Compared with the conventional electrical integrated control system 9, the frequency scanning method can only search for a specific frequency band, and often only supports the traditional infrared transmission in which the signal format conforms to a specific specification. The learning remote control system of the present invention does have the effect of expanding the applicable range.

In addition, the preferred embodiment of the learning remote control system of the present invention utilizes the wireless transceiver module to include a plurality of wireless transmitters, each of which is disposed in a different direction to expand the remote control transmitted by the wireless transceiver module. The coverage of the signal, so as to avoid the deadband of the signal transmission, so that the processing unit can smoothly send the remote control signal to all the electrical products in the space through the wireless transceiver module when the wireless transceiver module is disposed in any space. The remote control system does have the effect of improving the usability of the product.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
