Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the wireless code table of the utility model bicycle comprises power supply 1, IC processor 2, signal picker 3, display screen 4, wireless launcher 5 and wireless receiver 6.Described power supply 1 links to each other with IC processor 2, signal picker 3 respectively, described IC processor 2 is connected to display screen 4 and wireless receiver 6, be connected with pulse encoder 7 between described wireless launcher 5 and the signal picker 3, the input signal that described wireless launcher 5 is sensed signal picker 3 by pulse encoder 52 is encoded and is obtained at least two sections pulse signals, described wireless receiver 6 is after receiving the pulse signal that wireless launcher 5 sends, and decoding by 2 pairs of described pulse signals of IC processor obtains useful signal and show by display screen 4.
Wherein, described signal picker 3 is induction magnetic head or heart rate band, described induction magnetic head is corresponding with the induced magnet (not shown) on being installed in bicycle, calculate the data such as bicycle speed through inductor institute interlude out by induced magnet is double, the input signal that described signal picker 3 is sensed comprises the vehicle wheel rotation signal in one week, moving signal and the foot-operated signal that circles once of heartbeat.
Described pulse encoder 7 can be integrated in the IC process chip of wireless launcher 5, after described input signal sends to pulse encoder 7, encode by 7 pairs of these input signals of described pulse encoder, do not change the waveform of input signal during coding, whenever just signal is cut into two sections or several sections pulse signals after sensing a signal, every section pulse signal comprises one or several sine waves, the length of this pulse (sinusoidal wave quantity) can be set, and the interval duration between the pulse signal can be set.As shown in Figure 3, described input signal sends to behind the pulse encoder 7 and cuts into three sections pulse signals, the length D1 of described three sections pulse signals, D3, D5, and the interval between described three sections pulse signals is followed successively by D2 and D4.
The pulse signal that will obtain after described wireless launcher 5 will be encoded sends to wireless receiver 6 by wireless mode, described wireless receiver 6 is decoded by 2 pairs of these pulse signals of IC processor, judge namely whether the length of the multistage pulse signal that receives and interpulse interval duration are that (for example whether the length of three sections received pulse signals is D1 to preset value among Fig. 3, D3, D5, whether the interval between described three sections pulse signals is followed successively by D2 and D4), if, then this pulse signal is received and record as useful signal, and send to display screen 4 and show; If not, then this pulse signal is filtered as invalid signals.So just solved in the existing FM signal sine wave modulation and become weakened behind the square wave, so that the problem that the signal receiving range shortens.Accurately receive and record vehicle wheel rotation, heartbeat, foot-operated signal by wireless mode is remote, speed when having guaranteed motion, step on frequently, the accuracy of heart rate data.
The wireless code table of the utility model bicycle is encoded to the input signal of sensing by pulse encoder by the wireless code table of bicycle and is obtained pulse signal, wireless receiver receives behind the pulse signal by the IC processor it to be decoded and obtains useful signal, thereby increased the signal intensity that transmits, increased the emission receiving range, and can prevent effectively that other signal from disturbing, thereby improved the accuracy of recording mileage, speed, heart rate, stepping on audio data.
Here description of the present utility model and application is illustrative, is not to want with scope restriction of the present utility model in the above-described embodiments.Here the distortion of disclosed embodiment and change is possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that in the situation that does not break away from spirit of the present utility model or essential characteristic, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.In the situation that does not break away from the utility model scope and spirit, can carry out other distortion and change to disclosed embodiment here.
