4 is a control circuit diagram according to the present invention, and includes a period setting unit 1, an oscillator 2, an acoustic generator 3, and a melody generator 4. As shown in FIG. The present invention configured as described above can be used as a fresh flash at night by using two 1.5V batteries and a vibration sensor. By oscillating through positive feedback circuit, it sends out buzz sound and melody sound with parallax so that user can cope with the situation immediately. It is a vibration sensing sensor (when the voltage of DC power battery is applied). When the contact weight 33 of the 30 is connected to the ring-shaped contact 32 by vibration and is conducting, the period setting unit 1 applies a current to the oscillation unit 2 and the melody signal generating unit 4, wherein the oscillation unit ( 2) transmits the oscillation signal to the sound generating unit 3 by the positive feedback circuit so that the buzzer sound is transmitted with parallax, and the sound of the buzzer is completed and at the same time, the signal is applied to the melody generating unit 4 so that the melody sound is It is to be sent for a certain time.

The present invention configured as described above will be described in more detail as follows.

The present invention has a time IC (IC1) having two input and output gates and outputting a bias current according to different time constants determined by resistor R4, capacitor C1, and resistor R5 and capacitor C2. And a transistor (TR1) (TR2) having a time difference by a diode (D1) connected in parallel with the bias current output from the time IC (IC1) and connected to a power supply through the selector switch (50). A period setting unit 1 which operates according to the output of the sensor 30; Oscillator 2 which is oscillated by the positive feedback circuit provided by transistors TR3 and TR5 according to the output of the period setting unit 1 and outputs low frequency oscillation sound by resistors R7 and R8 and capacitor C3. Wow ; An acoustic generator 3 for amplifying the oscillation sound of the oscillator 2 with an output amplification transformer O.P.T and generating a buzzer sound through the buzzer BUZ; According to the output signal of the period setting unit 1, a melody signal is generated by the melody IC IC2 and amplified through the transistor TR4, and then the melody sound is transmitted through the buzzer BUZ of the sound generator 3. It is composed of a melody generating unit (4).

In addition, the lamp LAM and the vibration sensing means connected to the primary side of the output amplifier transformer O.P.T of the sound generator 3 can be selected by the user in some cases by the selection switch 50.

When described in detail with reference to the accompanying drawings the operation and effect of the present invention configured as follows.

After the main body is installed at a predetermined position of the fishing rod, the selection switch 50 is turned “on” to prepare for detecting the vibration.

When the quality of the meat is detected by the vibration sensor 30 in the prepared state, power is applied to the time IC IC1 provided in the cycle setting unit 1, and the time IC IC1 is a resistor R1 (R3). At the same time, the bias current is supplied to the transistors TR1 and TR2 to drive the oscillator 2 and the melody generator 4.

That is, the time constants of the buzzer sound and the melody sound are determined by the capacitance values of the resistor R4, the capacitor C1, the resistor R5, and the capacitor C2, and the bias current of the time IC IC1 during the predetermined time constant. Is applied to transistors TR1 and TR2 through resistors R1 and R3.

Accordingly, the transistors TR1 and TR2 are turned on by the bias current supplied to the resistors R1 and R3 at the same time, but the collector current of the transistor TR2 is reversed to the base of the transistor TR1 through the diode D1 connected in parallel. Since the bias current is applied to block the current, the transistor TR1 is cut off and the transistor TR2 is turned on.

That is, the reverse bias current applied to the transistor TR1 is applied by the resistor R5 and the capacitor C2 for a predetermined time, and the time constant is set to about 1 second in the embodiment of the present invention. The time constant determined by the capacitor C1 was set to about 10 seconds.

Even when a bias current is applied to the transistors TR1 and TR2 through the time IC IC1 by the time constant set as described above, the operation of the other transistor TR1 is applied to the diode D1 for one second, which is an operation period of the transistor TR2. After the reverse bias is applied, it is “off” and the reverse bias current is released only one second after the operation of the transistor TR2 is completed and is conducted for nine seconds, which is the set period of the transistor TR1.

The reason why the transistor TR1 is conducted for 9 seconds is because the period is 10 seconds, but the current is only 9 seconds since the reverse bias current is applied even during 1 second when the transistor TR2 is operated.

On the other hand, if there is meat grain during the operation period of the transistor TR1, the transistors TR1 and TR2 immediately repeat the operation, which is limited to the signal detected within 10 seconds, and the signal detected after 10 seconds is set again. The operation is performed again by the number.

Specifically, FIG. 5 illustrates a case in which there is no redetection after the first vibration is detected. The transistor TR2 operates for one second by the set time constant, and when the operation is completed, the transistor TR1 operates for 9 seconds, and when the vibration is detected again 2 seconds after the primary vibration is detected, as shown in b, transistor TR2 operates for 1 second and transistor TR1 operates for 2 seconds. In this case, since the vibration is redetected, the transistor TR1 is operated for one second again, and then the transistor TR2 is operated for the remaining time after subtracting the original period of 10 seconds, that is, for six seconds.

c shows the case where the vibration is continuously detected after the first vibration is detected. As described in the a and b diagrams, the transistors TR2 and TR1 repeat the operation and finally the transistor TR1 is inherently cycled. The remaining time subtracted from 10 seconds is operated, which means that the final operating time of the transistor TR1 is shorter than the original period when the vibration is continuously detected again.

In this way, the bias signal output from the period setting unit 1 is applied to the sound generating unit 3 and the melody generating unit 4, respectively, which are generated by the oscillating operation of the oscillating unit 2 provided at the front end. The buzzer sounds with a certain time difference.

That is, the oscillator 2 operates according to the time constant set by the period setting unit 1, which is provided as the transistors TR3 and TR4 after the collector current of the transistor TR2 is applied to the emitter of the transistor TR3. The oscillation signal is oscillated by the positive feedback circuit, and the oscillation signal is converted into the low frequency oscillation sound through the resistors R7, R8 and condenser C3, and amplified through the output amplification transformer OPT of the acoustic generator 3, BUZ) for 1 second and at the same time blinks the LED.

On the other hand, the transistor TR1, which is interrupted by the reverse bias current of the transistor TR2 of the period setting section 1, is turned on after 1 second to apply a signal to the melody generating section 4. At this time, the collector conduction current of the transistor TR1 is applied to the input terminal of the melody IC IC2 to drive it, and the melody signal output from the melody IC IC2 is first amplified by the transistor TR4 through the resistor R6. Next, the second amplification part, that is, the second amplification in the output amplification transformer (OPT) of the acoustic generator 3 emits a melody delay sound for 9 seconds and at the same time turns on the light emitting diode (LED) to allow the user to change the position at a long distance. Make sure to check. After that, if the vibration is not detected again in the vibration sensor 30 while the melody sound is transmitted, all signals are blocked and the first state is switched to the vibration detection standby state.

Therefore, the present invention is capable of capturing continuous fishery without additional manipulation by using one-touch fixing to the pedestal of the fishing rod as shown in the use state of FIG. 7, and also because the angle adjusting means of the main body is provided in the fixing means. Accordingly, it is possible to adjust the vibration sensitivity by adjusting the inclination of the body.

In more detail, according to the weather conditions, that is, when the wind is severely blown, the contact weight 33 of the vibration sensor 30 as shown in FIG. By making the inclination of the main body 100 perpendicular to the ground, the sensitivity is reduced to prevent the user's confusion caused by the wind. If the weather conditions are very good, the inclination of the main body 100 is shown in FIG. By adjusting the same so that the contact weight 33 of the vibration sensor 30 is close to the inner circumference of the ring-shaped contact 32, it is possible to capture even a very fine fishery.

In addition, the present invention is equipped with a visual and auditory means that can be captured at a long distance at night, so you can immediately capture the fish through the melody in the tent, and at the same time the light emitting diode is turned on to determine the position of the fishing rod accurately In addition to being able to visit, it can be used as a substitute for fresh flash at night by simple switch operation.

In addition, the vibration detection means and the alarm unit is integrated, not only easy to carry, but also has an advantage that can be quickly installed.
