The input value of position password is the setting value of present bit password, if induction channels have negative pressure gas flow when a upper Password Input, to
The setting value that the input value of the third bit digital password (and subsequent other positions) of input is equal to present bit numerical ciphers subtracts 1.
In third position when the above Password Input, when corresponding position induction channels have air-flow, baroceptor and red is needed
Outer photoelectric sensor receives signal simultaneously and just confirms the success of this Password Input.Since the PIN PAD is contactless defeated
The case where entering, being easy there are finger in input while being triggered to two infrared photoelectric sensors, by baroceptor come really
Give up into can reduce misoperation probability.In addition, due to the air pressure test side of baroceptor and the gas of connection venthole side wall
Pressure sensor meets Kong Liantong, and when venthole has air-flow to flow through, due to Bernoulli effect, venthole side wall forms negative pressure, air pressure
Sensor can judge that the induction channels of which position have air-flow to flow through by detecting the reduction of air pressure, convenient for confirmation Password Input
Whether device is in normal operating conditions, it is ensured that and input password goes on smoothly with setting code after inputting by setting rule and compares, from
And realize unlock.
Further, in order to realize automatic door opening, after completely inputting correct numerical ciphers, controller controls electric mortiser
Lock unlock；Electric pushrod pushes door body to open；Until pyroelectric sensor can't detect signal, electric pushrod resets, door
Body is closed, to realize that finger is in contact completely without with door body any part in entire door opening process, it is ensured that defend
It is raw.
In addition, inner panel, which is set as input password, realizes the mode opened the door, it is on the one hand still contactless in order to realize
Operation, while can also prevent children from arbitrarily opening the door, therefore inner panel only needs to input setting code, does not need as outer panels one
Sample inputs the dynamic password for capableing of peep-proof.

It illustrates below and the working principle of the invention is described further:
By outer panels unlock electric mortise lock when, it is assumed that setting code 246785,1,2,3,4 corresponding induction channels a of number and
The connection of positive pressure chamber, 6,7,8,9 corresponding induction channels a of number are connected to negative pressure cavity, and number 5,0 is blocked by baffle portion；
When unlocking electric mortise lock by outer panels, by finger close to 2 corresponding induction channels a of number, acoustical generator rings a sound, prompt the
One Password Input success, while centrifugal blower starts work；
Then by finger close to 4 corresponding induction channels a of number, acoustical generator rings a sound, prompts the success of second Password Input；
Since 4 corresponding induction channels a of number have positive pressure gas flow blowout, therefore then by finger close to the corresponding sense of number 7(6+1)
Channel a is answered, acoustical generator rings a sound, prompts the success of third position Password Input；
Since 7 corresponding induction channels a of number have negative pressure gas flow, thus it is then that finger is logical close to the corresponding induction of number 6(7-1)
Road a, acoustical generator ring a sound, prompt the 4th Password Input success；
Since 6 corresponding induction channels a of number have negative pressure gas flow, thus it is then that finger is logical close to the corresponding induction of number 7(8-1)
Road a, acoustical generator ring a sound, prompt the 5th Password Input success；
Since 7 corresponding induction channels a of number have negative pressure gas flow, therefore finger is then again adjacent to digital 4(5-1) corresponding sense
Channel a is answered, acoustical generator rings a sound, prompts the 6th Password Input success.
As it can be seen that setting code 246785, actually entering password is 247674 under present case.
After electric mortise lock unlock, it is assumed that controller controls stepper motor and distribution turntable is driven to rotate 72 °, so that number 3,
4,5,6 corresponding induction channels a are connected to positive pressure chamber, and 0,1,8,9 corresponding induction channels a of number are connected to negative pressure cavity, number
7, it 2 is blocked by baffle portion；
When unlocking electric mortise lock again by PIN PAD, by finger close to 2 corresponding induction channels a of number, acoustical generator rings one
Sound prompts first Password Input success, while centrifugal blower starts work；
Then by finger close to 4 corresponding induction channels a of number, acoustical generator rings a sound, prompts the success of second Password Input；
Since 4 corresponding induction channels a of number have positive pressure gas flow blowout, therefore then by finger close to the corresponding sense of number 7(6+1)
Channel a is answered, acoustical generator rings a sound, prompts the success of third position Password Input；
Since 7 corresponding induction channels a of number do not have air-flow, therefore then by finger close to 7 corresponding induction channels a of number, hair
Sound device rings a sound, prompts the 4th Password Input success；
Since 7 corresponding induction channels a of number do not have air-flow, therefore finger is then again adjacent to digital 8 corresponding induction channels
A, acoustical generator ring a sound, prompt the 5th Password Input success；
Since 8 corresponding induction channels a of number have negative pressure gas flow, thus it is then that finger is logical close to the corresponding induction of number 4(5-1)
Road a, acoustical generator ring a sound, prompt the 6th Password Input success.
As it can be seen that setting code 246785, actually entering password is 247784 under present case.
By being illustrated above it is recognised that a setting code unlocks the occurrence inputted when operation not phase in not homogeneous
Together, accordingly even when other people pry through the process that user inputs password intentionally, it can not also know the setting code of user, reach higher
Security level.
Further, the controller can control again distribution turntable and turn after the every input of user 1 or 2 passwords
It is dynamic that the state of the corresponding induction channels a of each number key is made to change, it is stolen difficulty with improving password, which number is specifically controlled
The corresponding induction channels a conducting of word, controller can be realized by pseudo random number.
Embodiment 2
The present embodiment makes following improvement on the basis of embodiment 1: it is greater than 1 when camera takes number in monitoring area,
Then password is inputted in the way of embodiment 1；It is equal to 1 when camera takes number in monitoring area, then inputs password and set
It is consistent to determine password, after inputting first password, centrifugal blower does not start.
Mountable voice cue module in the outer panels, when number is greater than 1 in camera takes monitoring area
Prompt " input dynamic password " prompts " input setting code " when camera takes when number in monitoring area is equal to 1.
The improvement of the present embodiment so that in password there is no unlocking electric mortise lock using setting code under being pried through risk situation,
Simplify password input mode；When in the presence of risk is pried through, the high security input mode of previous embodiment 2 or 3 is used.
