Background technology
It is widely used at present with gate control systems such as radio-frequency card, IC-card, Fingerprint Lock, coded locks on resident's anti-theft safety door,
Its operation principle is the signal that entrance guard sensor monitors radio-frequency card, IC-card, Fingerprint Lock, coded lock in real time, then starts gate inhibition system
The mechanical structure of system, so as to open door lock, therefore usually require individually to power to gate control system, to meet long-term use of want
Ask.For indivedual entrance guard facilities, the problem of by installation circuit modification, mains-supplied is often replaced using battery, then to whole
The energy consumption of gate control system proposes requirement.
" energy-saving two access controller, 201120389964.1 " disclose one kind by main control unit, signal to Chinese patent
Collecting unit, digital IO unit, communication unit, the gate control system of clock unit and memory cell, it is embedding with double low-power consumption
Enter the controller that declines, can significantly reduce the cost and power consumption of whole system, but be routine techniques, can not be by energy consumption
Minimize.
Utility model content
The utility model proposes a kind of low energy consumption entrance guard sensor, changes entrance guard sensor in the prior art and is chronically at
Energy consumption caused by machine testing state is treated, usually sensing system shutdown power consumption, the moment only before unlocking, sensing system is
In holding state, system energy consumption is greatly reduced.
Technology contents of the present utility model are as follows：
A kind of micro energy lose entrance guard sensor, including power supply, divider resistance, trigger switch, detection trigger unit, delay power supply
Unit and gate inhibition's unlocking unit, described divider resistance and trigger switch are sequentially connected in series between power supply and ground, described triggering
The input of detection unit and the low level end of divider resistance electrically connect, power supply and detection trigger unit and delay power supply unit electricity
Connection；After detection trigger unit receives the triggering energizing signal of trigger switch switching, driving delay power supply unit is opened for gate inhibition
Lock unit cuts off the power supply of gate inhibition's unlocking unit again after delay power supply a period of time.
In above-mentioned micro energy lose entrance guard sensor, trigger switch includes front panel and housing, and being provided with two on front panel connects
Touched electrode, lower housing portion are provided with two pins, and described contact electrode is turned on corresponding pin respectively, and described triggering is opened
Pass is arranged on around handle.
The utility model uses the minimum sensor detecting of standby period power consumption, is when realizing usually door lock closing
System is only to small part power elements such as the first divider resistances so that standby period system, which has, is less than 1uA level standby currents, only
After receiving trigger signal, and just powered within a period of time of delay to gate control system, saved energy consumption so that gate inhibition system
System can work long hours under battery powered.

Embodiment
As shown in figure 1, micro energy lose entrance guard sensor includes power supply, divider resistance 11, trigger switch 5, detection trigger unit
6th, postpone power supply unit 7 and gate inhibition's unlocking unit 8, divider resistance 11 and trigger switch 5 are sequentially connected in series between power supply and ground, touch
The low level end for sending out the input and divider resistance 11 of detection unit 6 is electrically connected, and power supply is powered with detection trigger unit 6 and delay
Unit 7 electrically connects；After detection trigger unit 6 receives the triggering energizing signal of the switching of trigger switch 5, driving delay power supply unit
7 be the power supply for cutting off gate inhibition's unlocking unit 8 after gate inhibition's unlocking unit 8 postpones power supply a period of time again.The wherein resistance of divider resistance
It is worth and is disconnected for 1M ohms, trigger switch 5 in usually holding state, the input connection high level of detection trigger unit 6；
When user opens the door, first touch trigger switch 5 so that trigger switch is changed into closing from disconnecting, the input of detection trigger unit 6
It is low level by high level upset, after the energizing signal sequentially enters detection trigger unit 6, detection trigger unit 6, which can drive, to be prolonged
After time of the slow power supply unit 7 for the delay power supply of gate inhibition's unlocking unit 8 about 5-10s, as long as prohibiting list of unlocking in this time inside door
Member 8 can normal door, once more than gate control system dump if opening time, can not open the door, if necessary to open the door, then need
Again touch trigger switch 5.So, usually under without triggering holding state, the standby current only less than 1 microampere, energy
Consumption is very low, and the stand-by time of gate control system also only has 5-10s after triggering, is different from traditional gate control system and continuously locates
In holding state, therefore serve the effect for saving energy consumption.
In said system, detection trigger unit can use single-shot trigger circuit, delay power supply unit to use RC circuits,
Other devices can be used to form, its object is to identify trigger switch 5 by the switching signal between being disconnected to closure, and postponed
A period of time is powered to gate inhibition's unlocking unit 4.Generally use metal-oxide-semiconductor and peripheral components composition, because metal-oxide-semiconductor has height defeated
Enter impedance and low on-resistance characteristic, be the ideal element of on/off control under the conditions of low standby energy consumption.
Wherein gate inhibition's unlocking unit 4 can use gate inhibition's unlocking systems such as radio-frequency card, IC-card, Fingerprint Lock, coded lock, this sensing
Device is intended only as a part for gate inhibition's unlocking system.
As shown in Figures 2 and 3, trigger switch 5 of the present utility model is arranged on around handle 2, before trigger switch 5 includes
Panel 35 and housing 33, two contact electrodes 31 are provided with front panel 35, and the bottom of housing 33 is provided with two pins 32, contacted
Electrode 31 turns on corresponding pin 32 respectively, and one end of pin is connected to ground, the low level end of the other end and divider resistance 11
It is connected.During unlocking, user switchs 5 front panel 35 with finger touch trigger so that two contact electrodes 31 turn on, whole to touch
Hair switch 5 is by disconnecting switching-on state, so as to produce triggering level upset so that the continued power one of gate inhibition's unlocking unit 8
The section time completes unlocking action.
Gate inhibition's sensor-based system of the present utility model only has a small amount of element of the grade of divider resistance 11 to have electric current to flow through when standby, will be
The standby current of system is reduced to microampere order level, largely extends the service life of battery.
