If not, the system goes back and performs the step C again to detect for a second time. If yes, the system performs the step D; D, the power supply is turned on and a timer starts timing; E, the far infrared probe detects whether a human body signal exists or not. If not, the power supply is kept to be turned on and the timer keeps timing. If yes, the timer is rest to be zero and the system goes back and performs the step D again; F, whether the time t is smaller than T or not is judged. If yes, the system goes back and performs the step E again. If not, a main controller controls and drives a circuit to control the operation of the motor by means of an active detection motor; and G, the far infrared probe whether a human body signal exists or not and the main controller controls the operation correspondingly.
Description
Technical field
The present invention relates to a kind of alarm, be specifically related to a kind of alarm with panoramic scanning and active probe function.
Background technology
Existing to utilize the alarm of far infrared probe be with the static placement of far infrared probe mostly, places like this to make being limited in scope that far infrared probe detects, and the generation dead angle that can not arrive stays opportunity to the robber easily.
Summary of the invention
The control method that the purpose of this invention is to provide the large far infrared alarm of a kind of investigative range.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of control method with alarm of panoramic scanning and active probe function, the method the when method when comprising switch connection and switch turn-off, specific as follows:
Method when switch turn-offs:
Steps A: the user sets T power cutoff after the time by button and display circuit;
Step B: after system powered on, power switch was in off state, and motor is in the state of quitting work, and established t=0 this moment;
Step C: far infrared probe surveys whether human body signal is arranged, and if not, return step C and continue to survey, if, execution in step D;
Step D: plugged, timer begins timing simultaneously;
Step e: far infrared probe surveys whether human body signal is arranged, and if not, then continues to keep power connection, and timer continues timing, if, timer zero clearing, again execution in step D;
Step F: whether interpretation time t less than T, if, return step e, if not, master controller is controlled motor operation by active probe Electric Machine Control and driving circuit;
Step G: far infrared probe surveys whether human body signal is arranged, and if not, master controller is by power switch controlling and driving circuits power cutoff switch, by active probe Electric Machine Control and driving circuit control motor operation, return step B, if, step D is returned in the timer zero clearing;
Step during switch connection:
Step a: during switch connection, alarm is started working, and master controller is by active probe Electric Machine Control and driving circuit control motor operation;
Step b: far infrared probe surveys whether human body signal is arranged, if alarm sends alerting signal, after master controller is received the signal that the pyroelectric sensor process chip sends, by power switch controlling and driving circuits plugged switch;
Step c: whether far infrared probe is surveyed human body signal, if, be failure to actuate, if not, master controller is by power switch controlling and driving circuits power cutoff switch;
Turn-off before the described power switch among above-mentioned steps G and the step c, judge first whether computer is in open state, if, close computer by the management software that is installed on the computer, if not, be failure to actuate.
In the technique scheme, after system powers on, switch disconnects, t=0, motor is not worked, namely adopt the passive detection mode, this state is called initial state, if any physical activity, the human body far infrared signal that far infrared probe focuses on Fresnel Lenses converts electric signal to and sends into the pyroelectric sensor process chip, the pyroelectric sensor process chip is sent into master controller after converting the electrical signal to standard signal, and master controller is by power switch controlling and driving circuits plugged switch, and timer begins timing simultaneously.When 0≤t＜T, master controller adopts the passive detection mode always, as detect again physical activity within this stage, then continues to keep power connection, simultaneously the timer zero clearing; As movable without human body in this stage, then still keep power connection, but timer continues counting, until t 〉=T enters the active probe pattern, namely master controller is by active probe Electric Machine Control and driving circuit control motor operation.When t 〉=T, master controller adopts the active probe mode, as detects human body information, then keeps power connection, and the timer zero clearing enters the passive detection pattern simultaneously; As do not have personnel to exist, and then cut off the electricity supply, the timer zero clearing, system returns initial state, waits for next time and triggering.
