Abstract
The utility model discloses a running velocimeter, which is provided with human body induction sensors (1). A signal processing circuit (2) is connected with the human body induction sensor (1). The output terminal of the signal processing circuit (2) is connected with a cordless transmitting circuit. A cordless receiving circuit corresponding to the cordless transmitting circuit is provided. The output terminal of the cordless receiving circuit is connected with an SCM via a trigger. The SCM is also connected with a display and a real-time clock chip. The exact time of 50-meter running can be tested automatically through the cordless transmitting and cordless receiving technology, and the tested time datum can be displayed exactly quickly. A plurality of human body induction sensors can be provided. The test operating time is shortened a lot by different working frequencies which can finish the 50-meter running tests of many people at the same time, so the operating strength of the tester is reduced. The running velocimeter is combined with a radio frequency IC card, and the datum in a natural state of the tested people can be obtained automatically. The convenience is provided for recording the tested result. The utility model has the advantages of low power consumption, safety, and high reliability.
Description
Technical field:
The utility model relates to a kind of physique test instrument, especially a kind of running knotmeter.
Background technology:
At present, relevant department has stipulated that school (primary school, middle school, university) must comprise the physical examinations of eight projects of " 50 meters races " to the student.The quality of physique constitution of students all has certain influence to enter a higher school, job hunting etc., and for this reason, detection means that must the employing science is carried out physical examinations to the student, to draw correct test result.In the past to the test of " 50 meters races " fully by manually finishing, need the examination of off flag and stopwatch two places side.Because the speed of 50 meters races of testee differs less, therefore once can only test a people.Exist shortcomings such as the manual time-keeping error is big, test job time length, tester's working strength height, the data of being added up can not reflect student's physical condition exactly.
Summary of the invention:
The utility model is in order to solve shortcomings such as existing in prior technology tester working strength height, error be big, but a kind of convenient test, the knotmeter of running accurately are provided.
Technical solution of the present utility model is: a kind of running knotmeter, be provided with human body sensor 1, and be connected to signal processing circuit 2 with human body sensor 1, the output and the radio transmitter of signal processing circuit 2 join; Be provided with and the corresponding wireless receiving circuit of radio transmitter, the output of wireless receiving circuit is joined by trigger and single-chip microcomputer, also is connected to display, real-time timepiece chip with single-chip microcomputer.
Be connected to the receiving circuit of issuing an order with single-chip microcomputer.
Described human body sensor 1 places in the support bar 3.
Also be connected to pilot lamp with single-chip microcomputer.
Described human body sensor 1 is released dependent sensor for people's body heat.
Also be connected to the IC-card signal processing module with single-chip microcomputer.
The present invention compares with prior art, utilizes wireless transmit, wireless receiving technology, can detect the correct time of 50 meters races automatically, and can fast accurately show the time data of detection.A plurality of human body sensors can be set, and 50 meters that finish in the same time many people by different frequency of operation are run test, and the test job time shortens many, has reduced tester's working strength.Combine with radio-frequency (RF) IC card and can extract tester's natural situation data automatically, for record test result etc. provides convenience.Circuit part is low in energy consumption, security good, reliability is high.
Description of drawings:
Fig. 1 is the scheme of installation of the utility model embodiment human body sensor.
Fig. 2 is the schematic block circuit diagram of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, 2: be provided with human body sensor 1, be connected to signal processing circuit 2 with human body sensor 1, the output and the radio transmitter of signal processing circuit 2 join; Be provided with and the corresponding wireless receiving circuit of radio transmitter, the output of wireless receiving circuit is joined by trigger and single-chip microcomputer, also is connected to LCD MODULE, real-time timepiece chip with single-chip microcomputer.Human body sensor is provided with a plurality of, is arranged in couples in the support bar 3.Human body sensor 1 or 2 can be a human infrared sensor, also for being that people's body heat is released dependent sensor.Also be connected to the control module operation keyboard with single-chip microcomputer, the receiving circuit of issuing an order, hummer, pilot lamp and IC-card signal processing module.Single-chip microcomputer can adopt the AT89s52 single-chip microcomputer, signal processing circuit is made of operational amplifier LM328, voltage comparator LM393, monostable circuit 74LS122, coding chip pt22612, pt22672 and potentiometer, resistance, electric capacity, radio transmitter, wireless receiving circuit adopt 315M, 433M radio receiving transmitting module, and trigger is selected Schmidt's Sheffer stroke gate CD4093, coding and decoding chip VD5026, VD5027 for use.
Principle of work: after making host-initiated work by the control module operation keyboard or by the receiving trap of issuing an order, internal timer picks up counting, and wireless receiving circuit is in accepting state.When the testee reached home, the signal of human body sensor induction amplified (generally being stabilized in about 2.3v) through operational amplifier LM358, sends into voltage comparator LM393 and compares.At this moment, 1 pin and 7 pin of voltage comparator LM393 will produce the negative level saltus step, obtain expanding behind the signal process monostable 74LS122 that is exported, promptly these two signals extension of validity, and then this signal conveys encoded to coding chip pt22612, launch by wireless transmitter module more afterwards.After wireless receiving module receives signal, be delivered to single-chip microcomputer after handling by trigger, single-chip microcomputer stops timing after receiving this signal, and pilot lamp is bright, and the data on the significant screen are the data that record simultaneously.After test was finished, single-chip microcomputer was noted data, and can achievement be existed on the card by wireless radio-frequency card.
The utility model is not only applicable to 50 meters and runs test, as long as wireless receiving circuit can receive the wireless transmission signal that is arranged on terminal point, can test.
