Abstract
The utility model relates to a passive type wireless monitoring device, comprising a passive infrared detection circuit, a trigger circuit and a wireless emission module circuit. Output signals of the passive infrared detection circuit are transmitted to the trigger circuit; output signals of the trigger circuit are sent to the wireless emission module circuit. The device is composed of an infrared detection assembly capable of remotely measuring mobile organisms, a wireless emission module, etc. When the infrared detection assembly detects infrared signal of human body movement, alarm signals are emitted to a host receiving module through the wireless emission module to realize wireless remote alarm. The passive type wireless monitoring device possesses the characteristics of small size, light weight, high sensitivity, small static state current, low costs, etc.
Description
Technical field
The utility model relates to a kind of supervising device, particularly be a kind of passive type wireless monitoring device.
Background technology
Along with intelligentized progressively ripe, the burglar alarm on the market is more and more, but it mainly be wired alarming is main.
The utility model content
The purpose of this utility model is to provide a kind of passive type wireless monitoring device.
The technical scheme that its technical matters that solves the utility model adopts is: the passive type wireless monitoring device, comprise passive infrared detection circuit, flip-flop circuit and wireless transmitter module circuit, the output signal of described passive infrared detection circuit is sent to flip-flop circuit, and the output signal of described flip-flop circuit sends to the wireless transmitter module circuit.
Described passive infrared detection circuit adopts RDP-18 passive infrared detection assembly IC to survey the infrared signal of physical activity, and the output terminal connection of described passive infrared detection assembly IC is connected to the first triode VT1 and the second triode VT2 successively through resistance R 1.
Described flip-flop circuit adopts the resistance R 4 of time base module IC1 and output terminal connection thereof, the monostable timing device that capacitor C 1 constitutes.
Described wireless transmitter module circuit adopts FDD-5 transmitter module IC2.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: compositions such as the passive infrared detection assembly that this device employing energy remote measurement biosome is moved and wireless transmitter module, detect the infrared signal of physical activity when the passive infrared detection assembly after, send alerting signal by wireless transmitter module to the main frame receiver module, reach the wireless remote alarming function, have that volume is little, quality is light, highly sensitive, characteristics such as quiescent current is little, cost is low.
Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, passive type wireless monitoring device of the present utility model, comprise passive infrared detection circuit 1, flip-flop circuit 2 and wireless transmitter module circuit 21, the output signal of described passive infrared detection circuit 1 is sent to flip-flop circuit 2, and the output signal of described flip-flop circuit 2 sends to wireless transmitter module circuit 21.
Described passive infrared detection circuit 1 adopts RDP-18 passive infrared detection assembly IC to survey the infrared signal of physical activity, the output terminal connection of described RDP-18 passive infrared detection assembly IC is connected to the first triode VT1 and the second triode VT2 successively through resistance R 1, the resistance R 4 that described flip-flop circuit 2 adopts time base module IC1 and output terminal thereof to connect, the monostable timing device that capacitor C 1 constitutes, after RDP-18 passive infrared detection assembly IC detects the infrared signal of physical activity, its inner repeated trigger chronotron just can be activated, output terminal output low level signal, make the first triode VT1 conducting through resistance R 1, also conducting thereupon of the second triode VT2, the 2nd pin of time base module IC1 is low level, and the monostable pressure trigger upset of being made up of time base module IC1 and peripheral cell enters temporary stable state.When the 2nd pin of basic mode piece IC1 is triggered by negative-going pulse at that time, its the 3rd pin output terminal is high level from low transition, through resistance R 5 current limlitings, make transistor VT3 conducting, be input to the 2nd pin of FDD-5 transmitter module IC2, and deliver to the 3rd pin of FDD-5 transmitter module IC2, namely modulation signal input end CP modulates the high-frequency signal of emission.The antenna Tx that FDD-5 transmitter module IC2 output terminal connects i.e. the external modulated frequency electromagnetic waves of emission, has that volume is little, quality is light, highly sensitive, characteristics such as quiescent current is little, cost is low.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
