Abstract
The present invention adopts a kind of new principle to survey faint mechanical shock, can produce the novel high sensitivity of a generation, high reliability burglar alarm, earthquake Alarm, vibration analysis register instrument and accurate vibration survey control system in view of the above.
Description
The invention belongs to electronics measurement and security alarm technical field.
The method and apparatus of surveying the milli machine vibrations at present mainly contains two big classes.The one, the light wave, electromagnetic wave and the hyperacoustic variation picked up signal that cause according to vibrations are as the dobla radar of various effects.The 2nd, the relative motion picked up signal that utilizes sensor to take place between vibrations process and inertia stationary machine parts is as inductance, electric capacity, resistance, strain and electromagnetic induction vibration detection method and device.The former installs complexity, latter's processing difficulties, and under the thump shock effect rapid wear.The present invention adopts a kind of new principle to survey faint mechanical shock, can produce the novel device of a class in view of the above, that its purpose is is easy, sensitive, survey small mechanical shock exactly, and a kind of advanced person's technological means is provided for related industries production, scientific research and police apparatus manufacturing.
The present invention adopts the electrical heating element that is immersed in the liquid substance to make sensor, the relative displacement of sensor and liquid substance causes the temperature variation output vibration signal of heater element when utilizing vibrations, after the sort signal amplification and handling, driving display or alarm, aforesaid sensor, signal amplify and treatment circuit and corresponding display or the novel little vibration detecting device of the common formation of alarm.
Embodiment is shown in accompanying drawing one.Device comprises airtight container (1) and the liquid wherein (2) of storing liquid, be immersed in the electrical heating element (3) in (2), detect the temperature sensor (4) of this electrical heating element temperature variation, for the circuit (5) of electrical heating element power supply with amplify because the circuit (6) of liquid electric signal of temperature of heating elements variation generation when producing relative displacement with electrical heating element, thereafter capacitance (7), vibrating state display circuit (8), reset circuit (9), shell (10), vibration signal output line (11), power lead (12), reset button (13), light emitting diode (14) and alarm (15), radio transmitter (16) is formed.
(3) and (4) be to have the heating and the same element of temp sensing function concurrently.It adopts the P-N knot of forward and reverse alternate conduction; It can also adopt the P-N knot of N series aiding connection, and N is any positive integer more than or equal to 1; It can also adopt transistor; It can also be a semiconductor thermistor; It can also be the resistance that metal material constitutes.
Capacitance (7) is between (6) and (8).
A reset button (13) and light emitting diode (14) are arranged (10).
There are a Displaying Meter (17) and (7) to link.
Application of the present invention is as follows:
1. make highly sensitive, high reliability burglar alarm;
2. make the novel household earthquake Alarm;
3. make wideband sound, great dynamic range vibration analysis and register instrument;
4. make accurate vibration survey control system.
