The enforcement principle of this detection system is: bicycle is scrunched frequency to vehicle condition signal projector 1 and the bicycle speed of a motor vehicle sends to bicycle code table 5 by radio signal, after bicycle code table 5 is received signal, on the one hand with data presentation on vehicle condition display 7; By code table 8KHz frequency emitter 8 data are sent to accutron 13 again on the other hand.9 of pectoral girdles send to accutron 13 by pectoral girdle 8KHz frequency emitter 12 with detected heart rate signal, step-counting signal.Accutron 13 receives above-mentioned signal by 8KHz frequency bin 14.The swimming parameter detecting parts 23 that accutron 13 itself also is provided with humidity temperature pickup 17, is made up of entry testing circuit 18 and acceleration detection circuit 19.Temperature, humidity, swimming stroke rate and heart rate, meter step, bicycle are stepped on data such as frequency, the bicycle speed of a motor vehicle and are finally all come together among the microprocessor 15, after data processing, are presented at one by one on the alphanumeric display 16.
The course of work to the present embodiment detection system describes below.
By bike the time, the frequency inductor 2 of stepping on of present embodiment detection system changes the action of treadled cycle into pulse signal input radio frequency transmitter 4; Simultaneously, speed of a motor vehicle inductor 3 is converted into pulse signal with the swing circle of bicycle wheel disc and also is input to radiofrequency launcher 4.Radiofrequency launcher 4 will be trampled pulse by turns and be transmitted in the vehicle condition signal receiver 6 in the bicycle code table 5 with 433.92MHz with the wheel recurrent pulse.After vehicle condition signal receiver 6 is received signal, divide two-way to carry: one tunnel signal conveys demonstrates on the bicycle code table and steps on frequently and bicycle speed to vehicle condition display 7; Another road is transported to code table 8KHz frequency emitter 8.Code table 8KHz frequency emitter 8 sends to 8KHz frequency bin 14 in accutron 13 with the wheel recurrent pulse with the 8192Hz frequency trampling pulse, and 8KHz frequency bin 14 is sent to the signal that receives in the microprocessor 15.Microprocessor 15 becomes to step on frequently and bicycle speed with the data reduction that receives, and these data are delivered to alphanumeric display 16 shows.
Electrocardio amplifying circuit 10 in the pectoral girdle 9 and meter step sensing circuit 11 are transported to pectoral girdle 8KHz transmitter 12 with heartbeat pulse signal and walking, running pulse signal.Pectoral girdle 8KHz transmitter 8 sends to 8KHz receiver 14 in the accutron 13 to information with 8192Hz, 8KHz receiver 14 is delivered to the signal that receives in the microprocessor 15, microprocessor is through calculating, the heart rate value and leg speed, the step that obtain per minute are worth frequently, and microprocessor 15 is delivered to alphanumeric display 16 with these numerical value and shown.
Like this, on accutron 13, just can see heart rate, step frequently, step on parameters such as frequency, the speed of a motor vehicle.
Temperature, the humidity of accutron 13 all right measurement environment.Humidity temperature pickup 17 in the accutron 13 is handled temperature, moisture signal input microprocessor 15, whether microprocessor calculates the sportsman and should keep the skin wet according to temperature, humidity, data after microprocessor 15 will be handled are delivered to alphanumeric display 16 and are shown, remind the sportsman to prevent dehydration.
Stroke rate when accutron 13 is measured swimming by swimming parameter detecting unit further disposed thereon.The principle of work of present embodiment swimming parameter detecting unit when measuring the swimming stroke rate is as follows: whether entry testing circuit 18 can enter in the water by perception accutron 13, is intended to send the signal that begins to detect the swimming arm stroke.Entry testing circuit 18 mainly is made up of the detecting electrode A and the cover entry signal amplification circuit that are installed on accutron 13 watchcases.Referring to Fig. 3 accutron schematic appearance, entry signal amplification circuit and acceleration detection circuit 19 are installed in the inside of waterproof accutron 13, have only detecting electrode A to expose on wrist-watch 13 shells, detecting electrode A is with wrist-watch 13 casing insulations and carry out the anti-hydropexis in slit.After accutron 13 entry, by the water short circuit, cause an entry signal amplification circuit output level---entry signal level between detecting electrode A and the Watchcase ground.This level transfers to microprocessor 15.Here, the function of microprocessor 15 is: only after receiving the entry signal level that entry testing circuit 18 sends, just begin the signal that interpretation is sent here by acceleration detection circuit 19.Microprocessor 15 is according to the signal of sending from acceleration detection circuit 19, the identification and the counting that carry out arm stroke.Count results removes to drive alphanumeric display 16 with coding form.Acceleration detection circuit 19 is to be made of 1 twin shaft acceleration sensing element and 2 transistors.Its major function is with the acceleration change of arm action, changes electric signal into.Exportable X-axis of twin shaft acceleration sensing element and Y-axis two paths of signals correspond respectively to acceleration change on the X-direction of acceleration sensing element and the acceleration change on the Y direction.X-axis and Y-axis are exported is fixed amplitude but the electric signal of pulse width variation, and the variation of these pulse widths is corresponding with the change of acceleration.
Fig. 3 is a swimming parameter detecting circuit diagram.In Fig. 3, U7 is a microprocessor, adopts chip 8F360.U13 is acceleration sensing element ADXL202.A is the entry detecting electrode.After the swimmer wears a wrist watch entry, the same Watchcase of entry detecting electrode A () connected by water, the current potential that causes the Q10 base stage reduces, and produces the entry signal.This signal is input to the 9th pin of U7 microprocessor by the ENTER-WATER interface, thereby makes the U7 microprocessor after receiving this entry signal after the Darlington circuit of Q10 and Q9 formation amplifies, and starts the program of interpretation stroke rate.When arm when striking, acceleration sensing element U13 in the wrist-watch, export the acceleration change signal that corresponds respectively to X-axis and Y-axis from the 5th pin and the 4th pin, these two signals are amplified by triode Q21 and Q22 respectively, signal after the amplification is respectively via STROKE IN and LAPI IN interface, the 8th pin and the 7th pin of input U7 microprocessor carry out interpretation for U7.The necessary condition that the U7 microprocessor carries out the stroke rate interpretation is: the output of the entry signal of entry detecting electrode initiation is arranged; The X-axis of acceleration sensor element output and the acceleration change signal of Y-axis are arranged.Entire circuit is for guaranteeing that such condition designs.In order to show stroke rate and draw speed that the 70th pin to the 132 pin of U7 microprocessor are connected on the LCDs LCD.For minute and speed, the 2nd pin, the 3rd pin of U7 microprocessor are connected to crystal oscillator, and its natural frequency is 4.9152MHz, for the U7 microprocessor provides required frequency of operation.After the U7 microprocessor is received the entry signal, even the of short duration water body that leaves of wrist-watch also can not influence the operation of interpretation program.Have only wrist-watch to leave water body and reached for 3 seconds when above, just can judge swimmer's water outlet, so end the interpretation program.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
