The camera shooting anti-theft alarm valve is characterized in that the input end of a storage type camera power supply is connected with a direct current power supply through a relay normally open switch and a power switch; a pin 8 of a 555 time base circuit is connected with an anode of a direct current power supply through the power switch; a pin 1 of the 555 time base circuit is connected with a cathode of the direct current power supply; a pin 5 of the 555 time base circuit is connected with the cathode of the direct current power supply through a second capacitor; a relay coil is connected in series with a horn, one connected in parallel with a voltage stabilizing diode is connected with a pin 3 of the 555 time base circuit and the other end is connected with the cathode of the direct current power supply; a pin 7 of the 555 time base circuit is connected with a pin 8 of the 555 time base circuit through a third resistor and is connected with a pin 2 and a pin 6 of the 555 time base circuit through a fourth resistor; the pin 2 and the pin 6 of the 555 time base circuit are connected with the cathode of the direct current power supply through a first capacitor; and the signal output end of the pyroelectric infrared sensor is connected with a pin 4 of the555 time base circuit through the first resistor and is connected with the cathode of the direct current power supply through the second resistor. By adoption of the technical scheme, the camera shooting anti-theft alarm valve has the advantages and positive effects of high practicality and low construction cost.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of camera shooting anti-theft warning valve.
Background technique
At present, the open-air various valves that use, stolen phenomenon occurs often, causes very large loss for people's production, life.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of camera shooting anti-theft warning valve is provided, when the people is arranged near this valve, can not only reports to the police, and the storage of making a video recording.
The technological scheme that its technical problem that solves the utility model adopts is: circuit is by storage type camera head, heat is released infrared senor, the first resistance, the second resistance, the 3rd resistance, the 4th resistance, the first electric capacity, the second electric capacity, 555 time base circuits, reference diode, relay, loudspeaker and power switch form, it is characterized in that: the storage type camera head power input is by the relay normally open switch, power switch links to each other with DC electrical source, 8 pin of 555 time base circuits link to each other with dc power anode by power switch, 1 pin of 555 time base circuits links to each other with dc power cathode, 5 pin of 555 time base circuits link to each other with dc power cathode by the second electric capacity, relay coil, loudspeaker series connection again with the reference diode parallel connection after an end and 3 pin of 555 time base circuits link to each other, the other end links to each other with dc power cathode, 7 pin of 555 time base circuits link to each other by 8 pin of the 3rd resistance and 555 time base circuits, 2 pin by the 4th resistance and 555 time base circuits, 6 pin link to each other, 2 pin of 555 time base circuits, 6 pin link to each other with dc power cathode by the first electric capacity, the signal output part that heat is released infrared senor links to each other by 4 pin of the first resistance and 555 time base circuits, links to each other with dc power cathode by the second resistance.With circuit original paper welding in the circuit board and place the warning circuit shell, and the warning circuit shell is fixed on the valve body, heat is released the infrared senor front the Fei Nieer lens.
Because adopt technique scheme, advantage and good effect that the utility model has are: practical, cost is not high yet.
