The present embodiment is as follows based on the work process of the safety control of light password:
S1) light scrambler 1 inserts reception controller 2, and this time scrambler 1 can switch 25 by forceful contact so that contact switch 25 conducting when light scrambler 1, reception controller 2 socket connection.
S2) control signal light emitting diode 27 circuit turn-on after contact switch 25 connection, produces scrambler control signal at coder module 26 drive control signal light emitting diode 27.
S3) the control signal light sensitive diode 122 of power control unit 12 decodes through decoder module 123 after receiving the optical signal of control signal light emitting diode 27, then the 3rd amplifying circuit 124 controlling to be made up of two-stage audion turns on so that light password generating unit 11 is in treats duty.
S4) pressing the button switch 113, light password generating unit 11 connects with power supply, and the light password light emitting diode 111#1 of light password generating unit 11～111#n produces the light code signal after coding.
S5) the light password light sensitive diode 221#1～#n of light password acceptance unit 22 receives light code signal; Now, there is following situation respectively according to the difference receiving result:
S5.1) light code signal is had correctly received. Now, light password acceptance unit 22 normally, the first amplifying circuit 231 is started working, the coil electricity of external equipment relay 232, thus controlling the normally opened of external equipment relay 232 or normally closed switch action, it is achieved the control to external equipment; The power supply indicator of second source output indicating circuit 234 is bright, prompting external equipment relay 232 normal operation, the coil 233#1 energising work of the first electromagnetic relay 233 simultaneously, the normally closed switch 233#2 making the first electromagnetic relay 233 in alarm unit 24 disconnects, and makes warning light sensitive diode 245 turn on without triggering alarm unit 24 even if delayed alarm lamp 115 started after 0.1 second.
S5.2) mistake light code signal is received, now it is divided into two kinds of situation: I) should be light password light sensitive diode 221 mistake putting out encoding state for bright, or existing light password light sensitive diode 221 mistake putting out encoding state that should be is for bright, also there is the light password light sensitive diode 221 that should be bright encoding state mistake for putting out, owing to all encoding states are that the light password light sensitive diode 221 putting out encoding state is connected with warning junction point 241, therefore warning junction point 241 has electric current to pass through so that the second amplifying circuit 242 drives buzzer 243 to report to the police. II) should be the light password light sensitive diode 221 of bright encoding state mistake for putting out, then delayed alarm lamp 115 started after 0.1 second and makes warning light sensitive diode 245 turn on so that the second amplifying circuit 242 drives buzzer 243 to report to the police. Meanwhile, the coil 244#1 energising work of the second electromagnetic relay 244, make the normally closed switch 244#2 of the second electromagnetic relay 244 disconnect, thus disconnect can not work controlling the power supply of the first amplifying circuit 231 in driver element 23.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention. It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
