Abstract
The utility model provides a human body movement direction detecting and sensing probe. The human body movement direction detecting and sensing probe comprises a pyroelectric infrared sensor, a signal amplifier, a controller and a positive and negative output circuit, wherein the pyroelectric infrared sensor is connected with the signal amplifier; the signal amplifier is connected with the controller; the controller is connected with the positive and negative output circuit. Positive and negative output is realized on one probe by the human body movement direction detecting and sensing probe, so that the problem that the current probe can output only in an on state or an off state is solved.
Description
Technical field
The utility model relates to security device field, refers in particular to human motion direction and detects inductive probe.
Background technology
Just for the existence of surveying human body whether existing human body sensing probe, general mode of operation is exported a signal for there being people to enter when search coverage and movement velocity are greater than certain value, representing in search coverage has personnel activity, blackout after personnel leave search coverage.Because these detectors are generally installed on passage, in the regions such as entrance, under a lot of applicable cases, people know have nobody to pass through except needs, also wish to know the personnel's that pass through direction of motion, at this time, existing human body sensing probe is just helpless.
Summary of the invention
The technical problems to be solved in the utility model, is to provide human motion direction to detect inductive probe, solves the problem that existing human body sensing probe cannot perception personnel direction of motion.
The utility model is achieved in that
Human motion direction detects inductive probe, comprise pyroelectric infrared sensor, signal amplifier, controller and forward and reverse output circuit, described pyroelectric infrared sensor is connected with signal amplifier, and described signal amplifier is connected with controller, and described controller is connected with forward and reverse output circuit.
Further, also comprise variable resistor Rd, described variable resistor Rd is connected with controller.
The utility model has the advantage of: direction that 1, can perception human motion; 2, can realize the existing human body sensing irrealizable function of popping one's head in, as one direction triggers inductive lightning control (can realize as entered and turning on light, go out turn off the light etc.) etc.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Embodiment
Refer to shown in Fig. 1, the utility model provides human motion direction to detect inductive probe, comprise pyroelectric infrared sensor 1, signal amplifier 2, controller and forward and reverse output circuit, pyroelectric infrared sensor 1 is connected 2 with signal amplifier, signal amplifier 2 is connected with controller, and controller is connected with forward and reverse output circuit.Wherein, pyroelectric infrared sensor 1 is for being converted into electric signal by the movement of the human body with infrared signature, this electric signal by signal amplifier 2 amplify and shaping after become stable signal, this signal comprises 2 groups of different RSTs, represent respectively two direction of motion, this signal is sent to controller subsequently to be identified and filters, and the forward output of finally controlling forward and reverse output circuit is that conducting or reverse output are conductings.Further, also comprise variable resistor Rd, described variable resistor Rd is connected with controller.Variable resistor Rd is for regulating the intensity of filtration.
The above embodiment, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, the equivalence of doing according to structure, feature and principle described in the utility model claim therefore all changes or modifies, and all should comprise in the utility model patent claim.
