Description
Technical field
The utility model is related to sensor field, and in particular to a kind of human body detection device.
Background technology
With smart home, the popularization of intelligent facility, Human Detection slowly into the sight line of people, and at present more
Common human body detection sensor includes temperature sensor, and pressure sensor, photoelectric sensor, acceleration transducer, heat is released
Electric transducer etc., and detection mode relatively conventional at present, sensor has two kinds of high level and low level by the type for exporting
State, and two states can be set to someone or no one by circuit, but so, although to sensor itself
Speech logic is relatively simple, but during to sensor Access Control chip, there is a problem, and control chip cannot judge sensing
Device type, it is necessary to which user pre-enters the corresponding configuration of sensor, causes trouble when user uses, and also improves control
Design cost produced by chip deployment cost and configuration of reservations command interface.
Utility model content
The purpose of this utility model is, there is provided a kind of people's health check-up of the human body detection sensor for adapting to different output types
Device is surveyed, above technical problem is solved；
The technical problem that the utility model is solved can employ the following technical solutions to realize：A kind of human testing dress
Put, for coupling human body detection sensor, the human body detection sensor resets level per the Preset Time of time delay first,
Also include edging trigger circuit, timing circuit and decision circuitry,
The edging trigger circuit is used for the edge signal of the output level for capturing the human body detection sensor and exports
Trigger is to the decision circuitry；
The timing circuit is configured with the second Preset Time and couples decision circuitry；
If in arbitrary second Preset Time, the decision circuitry does not receive trigger, then export first
Signal is to indicate nobody, if the decision circuitry receives trigger, exports secondary signal to indicate someone.
Because original human body detection sensor directly exports first/second signal, but cannot distinguish, the design changes
Judgment model, by edge level detection of the edging trigger circuit realiration to first/second signal, if such as sensor nothing
High level is persistently exported in the case of people, then when detecting someone and passing through, moment level is dragged down, now recognized by level edge
It may determine that now someone passes through, otherwise equally, if sensor is low level in the case of nobody, then detect someone Jing
Out-of-date, moment level is drawn high, and is now equally judged as that someone passes through by level edge identification；Regardless of whether whether people leaves, pass
Sensor all can automatically reset after the first Preset Time, and if people also exists, then after sensor resets, an electricity can be produced again
Flat change, during this period of time, edge signal is captured again, and does not meet the condition for reaching the second Preset Time, so will not
Nobody is judged as, but if all not sampling edge signal in the second preset time period, then judges that people leaves, first,
Judgement to actual scene will not produce larger error with original judgment mode, secondly, so arrange, and sensor is either
Normally opened or Closed type can meet design condition, improve the effect of design.
Further, the edging trigger circuit is configured to trailing edge triggers circuit, the trailing edge triggers circuit capture
Human body detection sensor output level trailing edge exports trigger.
Further, the edging trigger circuit is configured to rising edge triggers circuit, the rising edge triggers circuit capture
The human body detection sensor output level rising edge exports trigger.Triggered by rising edge triggers circuit or trailing edge
Circuit, it is possible to realize the triggering of rising edge or trailing edge, it is ensured that triggering effect and triggering precision, regardless of whether rising edge or
Trailing edge circuit, all can collect an edge signal, it is possible to the work of triggering following circuit when people passes through.
Further, the edging trigger circuit includes the rising edge triggers circuit and trailing edge triggering electricity being arranged in parallel
Road, the rising edge triggers circuit capture human body detection sensor output level rising edge output trigger, the trailing edge
Triggers circuit capture human body detection sensor output level trailing edge output trigger.So design, when once passing through, meeting
Two triggers of output, can equally meet output condition, and the different types of sensor response speed of correspondence is identical.
Further, the edging trigger circuit couples the timing circuit, triggers when the edging trigger circuit sends
During signal, the timing circuit resets and restarts timing, when the timing time of the timing circuit reaches second to be preset
Between when, the timing circuit controls the decision circuitry and exports the secondary signal.By the design of timing circuit, can meet
The requirement of timing, plays the effect of a timing.
Further, the edging trigger circuit is configured with the 3rd Preset Time, when presetting at interval of the described 3rd
Between gather once the output level of the human body detection sensor, when the institute at the output level and a upper moment of any time
When the difference for stating output level is more than preset value, the trigger is exported；3rd Preset Time is pre- less than described first
If the time.Porch is judged by this design, it is relatively simple reasonable.
Further, including for coupling the interface of human body detection sensor, the interface includes power pins and signal
Pin, the signal pins are used to couple the signal output part of human body detection sensor and receive the human body detection sensor
The output level；The power pins are used to couple the power end of the human body detection sensor and provide the human testing
Working sensor power supply.The design of this interface, in being more suitably applied pyroelectric sensor or infrared photoelectric sensor, side
Just directly using installation.
Further, second Preset Time is more than first Preset Time.Ensure that in this unmanned judgement
During, level can carry out once inside out.
Beneficial effect：Because using above technical scheme, the utility model is direct due to original human body detection sensor
Output someone/secondary signal, but cannot distinguish, and the design changes judgment model, by edging trigger circuit realiration to having
The edge level detection of people/secondary signal, if for example sensor persistently exports high level in the case of nobody, then detected
When people passes through, moment level is dragged down, now by level edge identification it may determine that now someone pass through, otherwise equally, such as
Fruit sensor is low level in the case of nobody, then when detecting someone and passing through, moment level is drawn high, now by level edge
Identification is equally judged as that someone passes through；Regardless of whether whether people leaves, sensor all can automatically reset after the first Preset Time, and
If people also exists, then after sensor resets, a level change can be produced again, during this period of time, edge signal is caught again
Obtain, and do not meet the condition for reaching the second Preset Time, so nobody will not be judged as, but if the second preset time period
Edge signal is not inside all sampled, then judges that people leaves, first, the judgement to actual scene will not be with original judgment mode
Larger error is produced, secondly, is so arranged, sensor is either normally opened or Closed type can meet design condition, carries
The effect of height design.
