Technical field

The utility model relates to the monitoring field, particularly be a kind of intelligent high-pressure path monitoring device.

Background technology

High voltage iron tower high voltage supply circuit is often done nest because of small bird between circuit, the capital causes a hidden trouble to transmission line of electricity, in case produce the high-tension line short circuit, will cause electric power system tripping operation outage, the serious threat that brings to electric power system will be produced transmission line of electricity and enterprise, people's life causes huge harm.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of intelligent high-pressure path monitoring device is provided.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of intelligent high-pressure path monitoring device, comprise ultrasonic transmit circuit, ultrasound wave receiving circuit and single chip machine controlling circuit, described ultrasonic transmit circuit is connected single chip machine controlling circuit with the output terminal of ultrasound wave receiving circuit, the correlation ultrasound wave of sonic wave transmitting circuit and ultrasound wave receiving circuit is exported control linkage GSM transmission circuit and voice alarm circuit after the single chip machine controlling circuit internal processes is handled judgement identification.

Described single chip machine controlling circuit also connects a watchdog circuit.

Described ultrasonic transmit circuit connects 6 groups of phase inverters by the ultrasonic emitting sensor and resistance constitutes.

Described ultrasound wave receiving circuit connects CX20106A ultrasound wave reception decoding integrated chip by the ultrasound wave receiving sensor and constitutes.

Described voice alarm circuit is made of the photo-coupler, triode, KMF5600 language chip and the LM386 audio frequency power amplifier chip that connect successively.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: this device adopts the ultrasound wave correlation to receive principle, ultrasonic transmit circuit and receiving circuit are installed in the high-tension line front and back respectively, in case when having bird to do nest, the ultrasound wave receiving circuit is just received reflected signal, and through the single-chip microcomputer processing controls, alerting signal is sent at the scene, and send alerting signal to power supply administration, the safety guarantee electric power system by GSM.

Embodiment

As shown in Figure 1, a kind of intelligent high-pressure path monitoring device of the present utility model, comprise ultrasonic transmit circuit 1, ultrasound wave receiving circuit 2 and single chip machine controlling circuit 3, described ultrasonic transmit circuit 1 is connected single chip machine controlling circuit 3 with the output terminal of ultrasound wave receiving circuit 2, the correlation ultrasound wave of sonic wave transmitting circuit 1 and ultrasound wave receiving circuit 2 is after single chip machine controlling circuit 3 internal processes are handled judgement identification, output control linkage GSM transmission circuit 31 and voice alarm circuit 32, described single chip machine controlling circuit 3 also connects a watchdog circuit 33, and the Automatic Program of single chip machine controlling circuit 3 is recovered.

As shown in Figure 2, by ultrasonic emitting sensor UN1,6 groups of phase inverter U2, resistance 2R1, resistance 2R2 etc. form ultrasonic transmit circuit, and by 6 groups of phase inverter UN2, resistance 2R1, resistance 2R2 forms the Transistor-Transistor Logic level circuit, by ultrasound wave receiving sensor UN2, the CX20106A ultrasound wave receives decoding integrated chip U3, resistance R 4, C1, C2 etc. form the ultrasound wave receiving circuit, after ultrasonic emitting sensor UN1 and ultrasound wave receiving sensor UN2 formation correlation (illustrating that it may be that small bird is being cooked nest that object is arranged between the high-tension line), the ultrasonic signal of its correlation is after ultrasound wave receiving sensor UN2 carrier modulation is amplified, form emission carrier signal with current field, this signal is after ultrasound wave receiving sensor UN2 receiving circuit amplifies, after demodulation also goes out original numerical coding pulse signal, send to single-chip microcomputer IC1 decoding.

The digital signal that ultrasound wave receiving sensor UN2 receives, receiving decoding integrated chip U3 gain amplifier through the CX20106A ultrasound wave is 60dB, the CX20106A ultrasound wave receives the 7th pin output pulse signal of decoding integrated chip U3, the full gain size is by the external resistance R 1 of its 2nd pin, the C1 decision, resistance R 1 is more little or capacitor C 1 is big more, it is high more to gain, adopt the peak detection mode, detection capacitor C 2, resistance R 2 is a bandpass filter, integrating capacitor C3, receiving decoding integrated chip U3 pulse signal through the CX20106A ultrasound wave handles, the 7th pin that is received decoding integrated chip U3 by the CX20106A ultrasound wave is exported to IC1 the 28th pin input end, after single-chip microcomputer IC1 inter-process is judged identification, send control signal output, the first via is by the 36th of single-chip microcomputer IC1 the, 37,38,39 pin and GSM transceiver module IC5, antenna TX etc. form the GSM datel circuit, send data-signal promotion GSM transceiver module IC5 by single-chip microcomputer IC1 and launch SMS alarm information to the operator on duty of power supply administration; The 8th pin output low level of secondary route single-chip microcomputer IC1 makes photo-coupler U4 conducting through resistance R 2, triode VT1 is conducting thereupon also, simultaneously KMF5600 language chip IC3 and LM386 audio frequency power amplifier chip IC 4 respectively electric work, KMF5600 language chip IC3 the 2nd pin output audio signal saves as in the KMF5600 language chip IC3 and " dies.。。" sound.This signal is added to LM386 audio frequency power amplifier chip IC 4 the 3rd pin through capacitor C 4 couplings, regulate adjustable resistance W and can change the sound power size, after capacitor C 6 couplings are amplified, promote loudspeaker Y by its 5th pin output through the amplification of LM386 audio frequency power amplifier chip IC 4 internal audio frequencies and send the high-power sound, frighten small bird away, reach prevention effect, avoid causing unnecessary economic loss because of high-tension line.Form watchdog circuit by 5054 watchdog chip IC2 and single-chip microcomputer IC1, form reset circuit,, prevent that single-chip microcomputer IC1 internal processes is in the endless loop state the 9th pin of single-chip microcomputer IC1 and the 7th pin of 5054 watchdog chip IC2 by resistance R 1, capacitor C 3.
