Description

A kind of omnipotent learning remote control device

Technical field

The utility model relates to a kind of remote controller, a kind of omnipotent learning remote control device of saying so more specifically.

Background technology

At present, the prior remote controller great majority can only carry out remote control by corresponding a kind of electrical equipment, improved universal remote control can carry out remote control to an electric appliances, but conversion trouble, fundamentally do not solve the remote control problem that a telepilot solves all electrical equipment of family, can not realize the non line of sight remote control, can not Long-distance Control.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, but provides a kind of and network, the omnipotent learning remote control device of scalable non line of sight remote control, remote-controlled multiple electrical equipment.

In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals: a kind of omnipotent learning remote control device, comprise master controller, display, hummer, keypad and infrared signal module, also comprise communication module and radio-frequency communication module, described display, hummer, keypad, communication module and radio-frequency communication module are connected with master controller respectively, described infrared signal module is connected with keypad, described communication module is RS232 module and USB module, and described display is a LCD.

Owing to adopt technique scheme, the beneficial effects of the utility model are: radio-frequency communication module mainly is responsible for non line of sight communication and networking, be connected with the remote controlled point in each room, can control signal, data be passed to the remote controlled point at place by addresses distributed, behind no mode of operation 30S, enter park mode, save electric weight; Infrared module is responsible for learning the coding of existing telepilot, and transmits the control signal of existing household electrical appliances, finishes the single remote controller function; The RS232 module is responsible for and the communicating by letter of host computer, and receives the instruction from host computer, and uploads the data of collection, and the USB module is responsible for the renewal of infrared coding data; Display panel module is gone back display remote controller work at present state except that the Presentation Function of realizing existing telepilot, the remote control unit number of access, and information such as addresses distributed behind no mode of operation 30S, enter park mode, and blank screen is saved electric weight; Keypad is realized the function of existing telepilots such as existing colour TV, air-conditioning, set-top box, DVD, and the partial function key is finished the conversion of different remote, and the part Macintosh is finished the transmission of simple networking function and control command; The voice suggestion of hummer complete operation action, the warning of warning that battery electric quantity is few and specifically defined data.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

As shown in Figure 1, a kind of omnipotent learning remote control device, comprise master controller, LCD, hummer, keypad and infrared signal module, also comprise communication module and radio-frequency communication module, described display, hummer, keypad, communication module and radio-frequency communication module are connected with master controller respectively, described infrared signal module is connected with keypad, and described communication module is RS232 module and USB module.Radio-frequency communication module mainly is responsible for non line of sight communication and networking, is connected with the remote controlled point in each room, can control signal, data be passed to the remote controlled point at place by addresses distributed, behind no mode of operation 30S, enters park mode, the saving electric weight; Infrared module is responsible for learning the coding of existing telepilot, and transmits the control signal of existing household electrical appliances, finishes the single remote controller function; The RS232 module is responsible for and the communicating by letter of host computer, and receives the instruction from host computer, and uploads the data of collection, and the USB module is responsible for the renewal of infrared coding data; Display panel module is gone back display remote controller work at present state except that the Presentation Function of realizing existing telepilot, the remote control unit number of access, and information such as addresses distributed behind no mode of operation 30S, enter park mode, and blank screen is saved electric weight; Keypad is realized the function of existing telepilots such as existing colour TV, air-conditioning, set-top box, DVD, and the partial function key is finished the conversion of different remote, and the part Macintosh is finished the transmission of simple networking function and control command; The voice suggestion of hummer complete operation action, the warning of warning that battery electric quantity is few and specifically defined data.Universal remote control need be simulated various remote controller signals, can not meet the demands with special chip, needs to produce control signal with single-chip microcomputer carrier wave is modulated, and the control signal of generation comprises preamble code, systematic code, data code and radix-minus-one complement; Home-use telepilot kind is many, collect difficulty of encoding ratio, universal remote control has learning functionality, coded signal to telepilot is gathered, the middle fracture of the input of the high-low level signal after demodulation single-chip microcomputer is triggered, the pulse width of record high-low level, and the complete coding of corresponding preservation produce control signal for radiating portion; Adopt the ZigBee agreement to finish radio communication and networking, need four kinds of basic frames of definition, beacon frame is used for managing each network, Frame is used for sending request, Data transmission, acknowledgement frame is replied the complete data that receive, and realizes reliable communication, and command frame is carried out specific operation; Designed two kinds of radio-frequency antennas, single-ended antenna and pcb board antenna all are unbalanced antennas, and the balun transformer that the microwave transmission line of electric capacity, inductance and PCB is formed makes antenna performance better, satisfies the needs of radio frequency I/O build-out resistor (50 ohm); Telepilot adopts powered battery, need to consider energy consumption, in this design, radio frequency power consumption maximum, if networking, power consumption is bigger, designed according to operating position close, hibernation, idle waiting, emission, five states of reception be corresponding with operation, when not needing radio communication, in off position, be in idle condition when needing networking.For a long time need not, be in hibernation-like state; Employing has the radio frequency chip of single-chip microcomputer function, and finish learning signal and handle, the protocol networking task, for alleviating the chip burden, carrier current channel has been adopted special-purpose oscillatory circuit, produces the carrier signal of 38KHZ, adopts and door and control signal modulation.

As shown in Figure 2, be networking synoptic diagram of the present utility model, universal remote control can use separately, also can form network by a plurality of telepilot nodes, interconnects by the ZigBee agreement, there are 16 channels selective, prevent the interference between heterogeneous networks and disturb that other is operated in the equipment of 2.4G frequency range in the family, each telepilot node distributes appropriate address, adopts star network, authentication inserts and guarantees security, and the Centroid telepilot that inserts host computer can be communicated to the instruction of host computer the node of appointment.

Above-described only is preferred implementation of the present utility model; should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model.
