Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail with reference to the accompanying drawings, and it should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

In order to achieve the design goal, the technical route selected by the invention is as follows: electromechanical remote control and audio and video communication transmission are realized by using the wireless smart phone. Wherein mainly include: dual tone multi-frequency (DTMF) encoding and decoding control techniques, two-way video call functions, voice recognition techniques, wireless charging techniques, and corresponding electromechanical control techniques. The GSM cellular communication network is selected to realize the transmission remote control function, special wireless transmitting and receiving equipment is not needed, a special radio link and an occupied frequency point are not needed, and the problem of additional radio communication regulation is avoided. The GSM cellular communication network is a mature public communication network, has high communication quality and stability, and can meet the requirements of the invention on communication and control in the GSM network coverage range. Under other conditions, such as in an unmanned area outside the GSM coverage, the satellite positioning function of the smart phone, such as short message communication of the beidou satellite, can still be expanded and utilized to realize the bidirectional communication transmission and control function with the controlled device.

The invention relates to a method for controlling and feeding back a remote and mobile target by using the call and video transmission functions of a smart phone, which comprises the step of transmitting bidirectional audio, video and electromechanical action commands. People can visually see and hear the effect of applying control and feedback at the control end or the controlled end to enable the control to be more precise, and voice, images and information can be transmitted between the control end and the controlled end, and even physical objects can be transmitted if the controlled end is a movable device. The invention can utilize the satellite positioning function, Wi-Fi signal recognition and image recognition function of the smart phone to control the movable controlled equipment to accurately reach the destination, accurately find the position of the target and accurately recognize and confirm the identity of the target. Due to the openness of most smart phones to a software system, the invention provides a space which can be developed by the later software of the smart phones, so that the function range and the intelligent degree of the system become more complex and perfect, and the controlled equipment is closely connected with the internet through the internet link function of the mobile phones.

The invention has the important achievement of simple and convenient operation, which can lead the invention to have the prospect of universal application. The smart phone is the most important personal belonging of people in modern society, and becomes the central equipment for personal communication and management, the proficiency of people in using the smart phone and the convenience in developing mobile phone apps make the communication management, information management and operation control by using the smart phone become the most accepted and popular modes, and the smart phone is simpler, familiar, easy to use and powerful in function compared with any special wireless remote controller, and the purpose of the invention is to change the smart phone into an intelligent control center.

Another important result to be achieved by the invention is that the remote control distance of the remote control system is substantially extended by operating the GSM-based cellular radio transmission network. The remote control distance between the control end and the controlled end of the remote control system is often an important factor for the practicability of the control action, the cost effectiveness ratio of the technical route, the size of the application range, and even the feasibility of the technical scheme. The invention is based on the GSM network, realizes the great extension of the remote control distance by using the existing mature public communication network as the basis, and can control the unmanned aerial vehicle to fly through a remote intelligent mobile phone in a place which can be communicated with a mobile phone telephone, for example, when the invention is applied to an unmanned aerial vehicle.

The telephone dialing code transmitted in the voice channel of the smart phone is called DTMF dual-tone multi-frequency code, which is a signaling mode code developed by Bell laboratories, and DTMF is the basis of "touch tone" (trademark of early AT & T) and is used for replacing the keys of a mechanical dial. Telephone dialing information is communicated over a voice-bearing telephone channel. Each digit on the telephone keypad is encoded with a sine wave of two different frequency burst patterns, a method for representing the digit in the voice channel by tone, which can be used to transmit signaling in an analog voice channel. The two-tone approach is chosen because it reliably distinguishes dialing information from speech. In general, a voice signal in a telephone channel is difficult to cause false triggering of a DTMF receiver.

Typically, the telephone dial pad is a 4 x 4 matrix (e.g., appendix-1) with one low frequency for each row and one high frequency for each column. Each key press sends a combination of high and low frequency sinusoidal signals, for example, a key "1" corresponding to the intersection of rows and columns of 697(Hz) and 1209(Hz), and the DTMF receiver of the telephone exchange can decode the frequencies of these combinations and determine the corresponding key press, automatically completing the long-distance call. It can be seen that DTMF is a 2-out-of-8 encoding technique. According to the recommendation of CCITT, 8 standard dtmf frequencies are adopted internationally, which are 697Hz, 770Hz, 852Hz, 941Hz, 1209Hz, 1336Hz, 1477Hz, and 1633Hz, and 16(4 × 4) different combinations can be formed with these 8 frequencies, thereby representing 16 different numbers or functions. The key signaling in the smart phone commonly used by us is also the DTMF coding and decoding technology. The invention uses DTMF coding to realize the transmission of keyboard control code, and uses voice channel to transmit voice and voice control command, and uses video call function to transmit video image.

DTMF codes and voice commands are transmitted in two directions by using a telephone voice channel and a keyboard dialing signaling coding system in the telephone voice channel, decoding electromechanical control is carried out by a receiving end, and video call function of the intelligent mobile phone is used for two-way mutual-view monitoring. The synchronous monitoring and control can be realized, the monitoring and the hearing can be controlled, and various means of interconnection and mutual control are implemented.

FIG. 1 is a block diagram of the system architecture of the present invention, wherein the system elements include: the intelligent mobile phone comprises a smart mobile phone, a GSM network, a video monitoring platform, a voice recognition control platform and a wireless charging platform, wherein the element composition in the figure is determined according to the task to be completed and is not limited to the above. It can be seen from the figure that the command is sent by the 'control mobile phone', the command is transmitted to the 'controlled mobile phone' through the 'GSM' wireless network, the 'controlled mobile phone' is connected with the 'helicopter' to execute the flight task, or is connected with the 'voice control platform' to execute the voice recognition control command, or is connected with the 'video platform' by the 'controlled mobile phone' to execute the video monitoring task, and the like. The system can be used for executing various target tasks, such as equipment with electromechanical actions, equipment with voice recognition control and image, voice, positioning and recognition function tasks of the smart phone. The wireless charging auxiliary platform can be directly connected and controlled by a 'controlled mobile phone', or indirectly interacts with a service object (such as a helicopter) to complete a charging task. The control mobile phone in the attached figure 1 has a plurality of control mobile phones, the controlled mobile phones also have a plurality of control mobile phones, the control mobile phones are marked by the identities of the mobile phone numbers of the control mobile phones, and the smart mobile phones have a three-party call function, so that the system has a control mode that one control mobile phone controls a plurality of controlled mobile phones or a plurality of control mobile phones control one controlled mobile phone. The smartphone call is bi-directional, as is DTMF encoding transmitted using the voice channel, so the control and controlled roles in fig. 1 are interchangeable.

Fig. 2 is a block diagram of an audio/video monitoring device, which is composed of a smart phone, a DTMF analysis circuit, and an electromechanical console. The receiving and the transmission of the audio and the video are completed by an audio and video receiving part and a transmission system of the intelligent mobile phone, the DTMF analysis circuit is responsible for analyzing the DTMF codes transmitted by an earphone interface of the intelligent mobile phone, the decoded command codes control the cradle head to rotate, and meanwhile, the cradle head drives the intelligent mobile phone to synchronously rotate. As mentioned above, the control and transmission of the system are bidirectional, and besides the sound and image received and transmitted back by the controlled terminal, the sound and image of the control terminal can also be displayed on the screen of the controlled terminal mobile phone.

FIG. 3 is a block diagram of a four-axis remote control helicopter, which is composed of a smart phone, a DTMF analysis circuit, a four-axis helicopter flight controller and a helicopter, wherein the smart phone and the helicopter are assembled into a whole. Similar to fig. 2, the command code interpreted by the DTMF analytic circuit is used to control the "flight controller" to command the helicopter to complete the flight action, and different types of unmanned aerial vehicles can be controlled by replacing different "flight controllers". In the process of flying the helicopter, the images and the sounds of the surrounding environment are realized by an image shooting function on a smart phone which is connected with the helicopter into a whole and are used for transmitting back the image information necessary for commanding the flight. The helicopter control example shows that the flight control of the traditional civil unmanned aerial vehicle needs a special 2.4GHz remote controller and a receiver to control the flight within the visual distance, if the flight control beyond the visual distance needs to increase a 5GHz image transmission channel and corresponding equipment, and the remote control distance is within several kilometers. By adopting the scheme, special remote control transceiving equipment is not needed, an industrial and medical channel (2.4GHz) and a video transmission channel (5GHz) are not needed, the transmission control distance is ultra-long (a GSM network coverage area), and the flight control and the video return of the unmanned aerial vehicle are integrally completed by the smart phone. In addition, the smart phone also has the functions of satellite positioning, face recognition, two-dimensional code recognition, image recognition control, voice recognition control, WiFi hotspot tracking and the like, and the functions can be completed at a controlled far end along with the flight of an aircraft.

Fig. 4 is a block diagram of a speech control device that does not require the parsing of DTMF codes, which are signaling transmitted over an analog voice channel, in the flow of a speech control application, as taught in the technical lines describing the present invention. The dual tone approach is chosen because it reliably distinguishes dialing information from speech, and normally, a speech signal in the telephone channel is difficult to cause false triggering to the DTMF receiver, so that DTMF signaling and speech signals can coexist in the analog voice channel without affecting each other. Therefore, in fig. 4, the speech recognition module and the recognized execution mechanism are connected to the earphone interface, so that the remote speech recognition control task can be completed.

Fig. 5 and fig. 6 are two block diagrams of the automatic charging and battery swapping platform, fig. 5 is a functional block diagram, and fig. 6 is a working schematic diagram. It is an auxiliary system in the present invention. The auxiliary system is called because the auxiliary system can be matched with a control mobile phone-a controlled mobile phone to complete a control task like the previous subsystems, and can also be matched with the helicopter subsystem to complete a specific task. The auxiliary system is not called because it is not important enough, and its importance is very high, and in the above "beneficial effects produced by the present invention", it is mentioned that: the wireless charging technology is an important component for the successful operation of the invention, and in order to enable the movable distance and range of the mobile equipment to meet the requirements of practical application, the invention has important significance for continuously supplementing electric energy to the mobile equipment midway besides increasing the coverage range of the remote control signal, and the invention can enable the movable range of the mobile equipment to realize infinite coverage in the true sense.

The basic functions of the charging and battery replacing platform are indicated in the attached figure 5, and the charging and battery replacing platform comprises a wireless charging coil module, a main coil is installed on the surface of the charging platform, an auxiliary coil is installed on the bottom surface of a helicopter, and electric energy is transmitted from the main coil to the auxiliary coil through the same-frequency resonance principle of the main coil and the auxiliary coil to charge a helicopter battery. The radar identification antenna is used for detecting whether a helicopter lands on the platform or not, and if the helicopter lands, a detection charging program is started. The connection fine adjustment is a set of mechanical alignment device, when the landing point of the helicopter is not accurate enough on the platform, the fine adjustment device can be started to move the helicopter to the correct position, and the working efficiency of the charging coil is the highest. The automatic battery replacement is also a set of mechanical device, and as the charging time is longer, for a specified helicopter with a standard model, the mechanical hand device can be used for directly replacing a battery which is short of electricity with a new battery which is full of electricity, so that the work efficiency of replacing electricity by the platform can be greatly improved.

In order to more intuitively represent the working principle of the 'automatic charging and battery replacing platform', a schematic diagram of the charging process of the helicopter is shown in the attached figure 6, wherein a 'satellite positioning parking point' in the figure is a platform which can facilitate the landing of the helicopter, has proper size and height and fixed GPS (global positioning system) coordinates, and the coordinate positions of the various 'automatic charging and battery replacing platforms' around the helicopter are stored in the helicopter or known by a 'control mobile phone' when the helicopter is in flight, just like the fact that a user drives the helicopter to get out of the door to know the position of a gas station. The flight control device of the helicopter has a GPS positioning function, and can fly according to set GPS coordinates to find coordinate points. After the coordinate point is found, the landing is executed according to the method shown in the attached figure 6, the landing is in butt joint with the radar on the parking point, and the charging and battery changing program is executed.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
