Embodiment
The circuit structure block diagram of handle of the present invention as shown in Figure 1, wherein button treatment circuit 104 adopts commonplace GPIO scan mode to realize, is used for function button is scanned, and key information is sent to main control unit 101; Bluetooth or RF module 102 are sent to host side with the control information of handle; It is very outstanding one chip bluetooth module that bluetooth unit wherein adopts BCM2042, integrated HID agreement and complete bluetooth protocol repertory, in addition the chip internal RAM that is integrated with 8051MCU and 8K have certain data processing function (can utilize its part work of sharing main control unit as: be responsible for realizing the back-end data processing of key scan and 3D motion and infrared module and the control function of other modules (motor etc.).As shown in Figure 5).RF uses NORDIG nRF24L01 scheme, its maximum characteristics are ultralow power consumptions, can in 1.9 to 3.6 voltage ranges, work, the data transfer rate of 2Mbit/s only needs very little working current, and peak-peak is 12.5ma, and SPCA563B is used in the data processing aspect, 16 u ' nsp MCU kernels, built-in 1K Words RAM, 32KWords ROM, and Flame Image Process DSP.Can replace the communication and the control function of bluetooth module.Can be in application according to only two kinds of communication modes being accepted or rejected with the demand of environment and cost.
The Controlling Source of vibrating motor 108 is from host side; The phonological component that control loudspeaker 109 take place selects to support the chip of WAV form, and the BU8844 that has disposed Rohm finishes decoding, and these functions all have more application in a lot of consumption electronic products, no longer describe in detail herein.Bluetooth or RF module 102 receives the feedback information that host side are passed back, and feedback information is sent to main control unit, after main control unit is handled, forms the control information of motor and loudspeaker, is used for controlling the vibration of motor and loudspeaker or sounds.
As Fig. 2, Fig. 3 and Figure 4 shows that the external shell of handle adopts the torch moulding, divide upper and lower two housings, wherein upper shell 202 be level and smooth cambered surface design, is provided with button 201 in the above and reaches (the silica gel liner of not looking among the figure, loudspeaker, LED leaded light post etc.); Lower house 203 is main supporting body, adopts the nearly face of cylinder design of axis curvature, and is provided with hand-held projection 204, (the far infrared lampshade of not looking out among the figure, button and silica gel keys, PCB support, battery component, modules such as CCD camera assembly and motor) at its rear portion.The accessory of other of handle all takes asymmetrical design to reach to prevent the effect of mistake assembling, and this has improved the efficient that difficulty has but promoted streamline in design.This product will be worked in the mode of motional induction simultaneously, and is higher to the antidetonation stability requirement.One is to guarantee design accuracy on structural design, the tolerance of final products for+/-0.1mm another be that design complexities all can be provided with identical fixing groove for each annex on last lower casing, assemble the product of finishing and can make the steady close combination of all accessories.Each accessory is firmly to prevent to come off and can adopts buckle and elastic mounting mode, and the assembling of final products only needs two assemblies are closed tightly with the power of buckle, and technological process is easy, is beneficial to production.
General infrared location needs two module collaborative works to realize infrarede emitting diode unit group and infrared module 106.Be illustrated in figure 5 as the process flow diagram of direction determining method, be the movement direction decision method of operating grip.Comprise the steps: at first the infrarede emitting diode unit to be fixed on the reference position, in order to the emission infrared signal, wherein the effect of infrarede emitting diode unit is fairly simple, it is made up of two groups infrarede emitting diode group, the infrared optics signal is just launched in their work, and these non-visible light signals will be picked up (as the benchmark of the elements of a fix) with fixing frequency sweeping by the CMOS in the infrared module 106 of handle, send to main control unit with the two dimensional image likeness in form; It will provide a reference coordinate for optical positioning system in fact, therefore the putting position to it also has specific (special) requirements, be the infrarede emitting diode group must be placed on the display screen of host side the middle (according to the practical operation needs, because people point to display screen with telepilot when media devices such as TV are carried out remote control), every group of a plurality of infrarede emitting diode settings can produce very big emission angle, make use in fact more convenient.Infrared module 106 places within the handle, and the lampshade that sees through the handle front portion receives the infrared signal of infraluminescence pipe.The effect of lampshade is the visible light that filters external environment, and handle is worked under various light environments.CMOS camera in the module (360*296 resolution) meeting is with the rate scanning image of 30fps, and the signal that it can scan promptly is two groups of infrared light supplies (step 601) of the infrared pipe of giving out light; The two dimensional image that main control unit is passed back infrared module 106 compares, and the position of seeing the infrarede emitting diode in this scan image is with the position of the infrarede emitting diode in the last time scan image whether change (step 602) that compare; If change, then calculate the change information (being the coordinate data information that these two groups of data differences draw centre of location point) of the relative position of the infrarede emitting diode unit in the two adjacent images of its reception, the data that such each frame picture is relatively obtained link up, just can think the motion track of telepilot, realize the direction-pointing function (step 603) of two-dimensional coordinate face with this; Main control unit sends to host side (step 604) with the handle moving direction information in the step 603 after by bluetooth or RF module; If no change then return step 601.In actual the use, the position of infrarede emitting diode unit is constant, camera (COMS) in the corresponding handle then constantly changes the position, both relative positions constantly change, camera is with these information of frequency record of per second 30 frames, what these data reflected is to be the coordinate information of two groups of infrared light supplies of reference with camera oneself, relending the infraluminescence pipe that helps software algorithm just can judge with fixed position (display screen) is object of reference, the change in location of camera or handle, in application software, then be presented as the shift position of cursor on the screen of host side, and taking the form of by the software of host side of cursor finished dealing with, and communicating by letter between the coordinate data that infrared module provides and the main frame realized by bluetooth module or RF module.The working mechanism of the very similar human eye of this principle, different is, and the infraluminescence pipe can only emit beam and camera can only be accepted light, the light path of two kinds of systems is just in time opposite, so we also need processor in the module to the station-keeping data computing, the changes in coordinates that infers camera just can realize direction-pointing function.
In addition, be that acceleration transducer is once introduced to the core of 3D motional induction unit, the spatial control ability of 3D module relies entirely in this.The MMA7360 acceleration transducer has adopted signal condition, single pole low-pass filter and technique for temperature compensation, provide 4 ranges optional, corresponding different sensitivity is selected, and reaches as high as 800mV/g @ 1.5g, and integrated low-pass filtering is used as zero g compensation, makes that the location is more accurate.It is a kind of MEMS device of high precision.Its measurement principle to the spatial triaxial action is the voltage signal that changes output according to the variation of the direction of displacement and speed.The effect of simply saying the action induction module is exactly an action collector, its input is the variation of locus or perhaps the variation of acceleration, and output is a voltage signal by sensor output, via digital sample, be quantified as digital signal and be sent to host side by bluetooth module or RF module.We can be object of reference with the earth generally speaking, and have the gravity coefficient (acceleration) of 1g on the vertical direction of the earth.As in figure below we at first sensor laterally, vertical, vertically be defined as himself X, Y, Z axle, distinguish mutually with three of space X YZ that with the earth are reference.When the Y-axis of sensor is vertical with the earth, be output as 2.45V at the voltage of Y-axis, and the axial acceleration of XZ is 0g, voltage output 1.65V.And acceleration to be vector have directivity, spatial triaxial with+/-expression, and-output of 1g correspondence is 0.85V.Above-mentioned be sensor under static state, the variation of position (placement direction) corresponding different output signal, by these data, we just can judge the current state of sensor (handle), and are promptly horizontal, perpendicularly put or indulge and put.Sensor can be sensed small acceleration change and give corresponding voltage output, place with the angle that tilts such as sensor, the voltage output that is different from the 0g state all can be arranged three of XYZ on axially like this, host side software relatively can be judged the current laying state of sensor (handle) with the data of three kinds of states shown in itself and the last figure.If this moment, an either large or small motion took place in sensor, sensor equally can be with the form output of this motion change with voltage signal, ADC in the motional induction module is with in the axial (X-axis of three-dimensional to the principle of sensor voltage analog signal processing, Y-axis, the Z axle) acceleration interval-3g on～+ the 3g equal interval quantizing is 0～255 8 position digital signal intervals, only needs handle in host side to 8 digital signal or its corresponding acceleration.What host side was not stopped obtains action acquired signal via the sensor of digital quantization from bluetooth module or RF module, and the various controls that just actual motion of sensor can be mapped as in the application software are used.
Be noted that at first handle is not that all modules all play a role simultaneously when work, infrared module 106 in the system, 3D motional induction unit 105 and button treatment circuit 104 all possess the characteristic of input unit, they can operate control to the application software of main frame, from forming, system can see three relatively independent being independent of each other of module, can produce input simultaneously, also can have only one group after two groups input is arranged; Motor 108 and loudspeaker 109 in the system have the characteristic of follower, produce vibration or disengage voice signal.Bluetooth module or RF module be responsible in the system each module and host side communicate by letter with, in running order all the time.The signal that input unit is produced that it does not stop is delivered to main frame wirelessly, and the feedback information that also will receive main frame simultaneously sends control command to follower.
By way of example, when handle is upwards lifted suddenly, and not to other direction motion, 3D motional induction unit is believed this and is sent to main control unit, sends to host side after main control unit is handled, and the numerical value that just is equivalent to only to detect in the host side system Z axle is become 255 maximal value by initial value, also promptly have at the acceleration of Z axle+1g is changed to-3g, corresponding X simultaneously, the output of Y-axis has only very faint variation, and promptly these two acceleration change on axially are very faint.Host side application software obtain these information that action induction module output is arranged by the bluetooth module after can be sent the control signal of upwards jumping over, and is that the mode of motion of controller upwards lifts fast just and promptly reaches along space+Z-motion at this moment; Can show as in main control end, leading role in the application software can be the gymnast, the realization (can also only realize this operation by next operation push-button) of jump action has above been described, by bluetooth or RF module information is delivered to host side, application software receives after the control information it just can is the action (accessing the animation of this group action in other words conj.or perhaps) that the leading role finishes 360 degree and turns round, if this a series of action is finished, application software can be sent a prompt command, bluetooth or RF module can be operated follower after receiving this signal, make motor operations handle generation seismaesthesia in addition, and will deliver to the voice module by the voice signal that main frame sends, loudspeaker then sends the audio that spectators applaud.
Enumerate the application of a picture browsing again, the main effect of infrared module performance here.Cursor can be made as hand-type in the Photo Browser, above described, the working mechanism of infrared module, handle is pointed to the direction of picture, cursor also can rest in the screen on the picture, push button, bluetooth or FR module are delivered to host side with information, software obtains behind the signal cursor being become the fist of holding with a firm grip by open both hands, at this moment left (X-axis) whipping handle, the bluetooth module can be delivered to main frame with the digital signal of action induction module, and software can be done two things after receiving instruction, at first judge current state, picture is in the lock state; Send the order of page turning simultaneously, browser can show next pictures.And if two sections programs successful execution all, application software is sent prompt command simultaneously and is had the bluetooth module to deliver to the output of handle, the control motor operations makes the voice module send the rustle of reaction page.
The above; only be the preferable embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
