Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the circuit theory diagrams of circuit board in the utility model.
Detailed description of the invention
As shown in Fig. 1-Fig. 2, electronics comes and goes and runs end line touch device, comprise fixed bar 1, the lower end of fixed bar 1 is provided with the needle-like head for fixing with ground, fixed bar 1 bottom is provided with for anti-down baffle plate 2, and the upper end of described fixed bar 1 is provided with rectangular housing 3, is provided with circuit board 5 in housing 3, housing 3 top is provided with presses plate 4, presses plate 4 and links with circuit board 5.Described circuit board 5 comprises battery DC, K switch, loudspeaker L, resistance R1R4, electric capacity C1C3, IC, the positive pole of button AN and diode D1D2, battery DC is by 8 pin of K switch and IC, one end of first resistance R1 and one end of button AN are connected, the other end of button AN is connected with the positive pole of the positive pole of the first diode D1 and the second diode D2, the negative pole of the first diode D1 is connected with one end of the other end of the first resistance R1 and the second resistance R2, the other end of the second resistance R2 is connected with one end of the 3rd resistance R3 and 7 pin of IC, the other end of the 3rd resistance R3 and one end of the second electric capacity C2, 2 pin of IC and 6 pin of IC are connected, the positive pole of the second diode D2 negative pole and the first electric capacity C1, one end of 4th resistance R4 and 4 pin of IC are connected, and 3 pin of IC are connected with the positive pole of the 3rd electric capacity C3, and the negative pole of the 3rd electric capacity C3 is connected with one end of loudspeaker L, the negative pole of described battery DC and the other end of loudspeaker L, 1 pin of IC, the other end of the second electric capacity C2, the other end of the 4th resistance R4 and the negative pole of the first electric capacity C1 are connected, the model of described IC is NE555, described button AN with press plate 4 and link, press and press plate 4, the button AN closing of contact, unclamps and presses plate 4, and button AN contact disconnects.Described battery DC is rechargeable battery, and its voltage is 12V.
During use, fixed bar 1 is inserted ground by needle-like head and is fixed, and make anti-down baffle plate 2 and earth surface, prevent fixed bar 1 in round race process from toppling over, when coming and going race, after examination person arrives end line, as long as hand presses down press plate 4 once.
IC in Fig. 2 is time base circuit integrated package 555, and it and its peripheral cell form astable multivibrator.When pressing the button AN, oscillator vibrates, frequency of oscillation is about 700Hz, and loudspeaker sends the sound of about 700Hz.Meanwhile, power supply charges to the first electric capacity C1 by the second diode D2.When decontroling button AN, the first electric capacity C1 is just discharged by the first resistance R1, maintains vibration.But due to the disconnection of button AN, the first resistance R1 is sealed in circuit, makes frequency of oscillation change to some extent, is approximately about 500Hz, and loudspeaker sends the sound of about 500Hz.
Help without the need to support staff like this, can complete once to come and go and run counting, easy to use, the burden of examination personnel can be alleviated, and also good by needle-like head stationarity, position is fixed, and is beneficial to examination and uses.
