Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of touch remote controller, comprise user's operational module 1, central processing unit 2, RF transceiver module 3, described user's operational module 1 comprises capacitive type touch pad 4 and button operation end 5, the output terminal of user's operational module 1 links to each other with central processing unit 2 input ends, the control signal of capacitive type touch pad 4 and button operation end 5 is flowed to central processing unit 2, central processing unit 2 output terminals link to each other with RF transceiver module 3 receiving ends, RF transceiver module 3 transmitting terminals link to each other with central processing unit 2 input ends, and described RF transceiver module 3 adopts RF4CE agreement and user terminal 6 to carry out two-way communication.If user's finger slides on the touchpad operation end, the electric capacity of operating point on the touch pad is changed, and the coordinate signal that the special use control IC that establishes in the touch pad will detect the capacitance change of user's operating point position and convert X, Y-axis to transmits to central processing unit 2.Its detailed process is: the chip drives charge pulse of establishing in the described touch pad 4 is by the sheet metal behind the touch pad, and outwards send electric field by touch pad, and when the finger near the time, electric field will be disturbed, just can detect the position of finger by measurement from the change amount of four jiaos of electric charges that collect or that send of touch pad, and then use algorithm to process the signal into X, Y-axis coordinate.This capacitance touch control chip can offset drift thereby has been overcome calibration aging and that environmental change brings and depart from; The method of using the very long random pulses of burst interval to carry out the spread spectrum charging has greatly reduced power consumption, radio-frequency radiation and electrical Interference susceptibility; In addition, owing on the touch pad Y-axis, adopt multiple spot to connect, thus spatially isolated the capacity cell that forms by place, contact staff shade, the staff shadow effect also has been eliminated.Described central processing unit 2 receives X, the coordinate signal of Y-axis and the button operation instruction of reception button operation end 5 that capacitive type touch pad 4 sends over, and is converted to the receiving end that coordinate signal and control signal output to RF transceiver module 3.Described RF transceiver module 3, in be provided with a RF4CE radio frequency IC, the coordinate signal and the control signal of central processing unit 2 output is converted to the RF signal form and sends to user terminal 6, terminal device is controlled.But RF transceiver module 3 is the feedback signal of receiving terminal apparatus also, sends to central processing unit 2 after decoding, so that the user operates the control interface.
Software control implementation procedure of the present invention as shown in Figure 2, carry out initialization after telepilot powers on, whether central processing unit 2 detects telepilot after the initialization has operational order or RF transceiver module 3 whether to receive feedback signal, if do not have, then enter power-down mode, open interruption simultaneously; Coordinate signal or the button operation instruction of button operation end 5 or the feedback signal input of user terminal 6 as if the X that has touch pad 4 to send over, Y-axis then enter interrupt routine, trigger telepilot and enter mode of operation, close interruption then.Central processing unit 2 enters the task enquiry module, detect the kind of command signal, and call that corresponding processing module is converted into coordinate signal or control signal is input to RF transceiver module 3, the conversion of signals that RF transceiver module 3 will receive from central processing unit 2 is to send to user terminal 6 behind the RF signal; If it is the user terminal feedback signal that the task enquiry module detects, then it is handled and takes control corresponding.
The present invention is based on the remote control mode of radio-frequency technique, different with infrared remote control, under the identical condition of controlling, adopt the RF4CE technology of IEEE802.15.4 radio-frequency technique can easily reach 20 to 50 meters connection distance, and its physical characteristics make that controlling signal can penetrate the object that wall, carpet and home entertainment center etc. intercept sight line.This makes telepilot also can play a role in not visible scope.After remote control outside the sight line became possibility, it is indispensable that information feedback function becomes.Because, the telepilot user need know controlling signal and whether being accepted of sending, information such as correct execution so that understand the practice condition (as the play position of video, progress of network download or the like) of operation at present in real time, so just needn't usually be gone to the equipment front and go the situation of checking.And realize that it is exactly two-way communication that these functions get basic, this is easy concerning the RF4CE technology, and the Infrared remote controller of one-way communication is just powerless.Thus, the present invention adopts touch-screen to realize mouse function, cursor on the flexible operation control terminal device screen of energy, and adopt RF4CE communication protocol, overcome a series of technological deficiencies of existing Infrared Ray Remote Control Technology, make transmission range increase, possess penetrate thing ability, super low-power consumption greatly, especially promoted the two-way communication between telepilot touch pad and the user terminal, help to realize abundant more user interface, more convenient operation, strong functions more.
Though what present embodiment was mainly described is capacitive type touch pad, also can use the touch pad of other form without departing from the scope of the invention.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
