(4) signaling control unit:

Human body pyroelectric sensor RT and chip IC ₁Form human test's element circuit, chip IC ₂And R ₂, R ₄, RW, C ₁, C ₂Form multi-resonant oscillating circuit, chip IC ₃, IC ₄Form display circuit, chip IC with seven sections common cathode charactrons ₅Form voice reminder element circuit, chip IC with loudspeaker Y ₆, IC ₇And IC ₈Form signal Processing and logic judging circuit.

(5) signal principle of work:

Human body pyroelectricity infrared ray sensor RT detects people's activity in the appointed area, produce the electric signal of about 2.5V at S end, input and non-chip IC ₁8,9 pin upsets output to the Sheffer stroke gate chip IC for behind the electronegative potential by 10 pin ₈2 pin, 3 pin are then exported noble potential, are added in triode Q ₁Base stage, triode Q ₁Saturation conduction makes controllable silicon D ₅Conducting is by D ₁-D ₄The bridge rectifier loop conducting of forming obtains AC power at the 220V output terminal.S end output electronegative potential when unmanned activity is then in chip IC ₈Lower margin is a noble potential, because chip IC ₈So the right and wrong gate circuit is chip IC ₈2 pin inputs noble potential, the current potential of output terminal 3 pin depends on the current potential with the other end 1 pin.

When human body pyroelectricity infrared ray sensor RT detects in the appointed area nobody, S end signal input nand gate IC ₁8,9 pin change 13 pin output noble potential through two Sheffer stroke gates, start chip IC ₂, 555 multi-resonant oscillating circuits are started working, and produce the pulse signal (frequency is adjustable by RW) of certain frequency at 3 pin.Chip IC ₃, IC ₄Be the decimal subtraction counter,, can finish schedule time time-delay, can show that by charactron the double figures sign indicating number counts down by 7 foot control systems.When being zero to counting, chip IC ₂11 pin output negative pulse at chip for driving IC ₅In the time of sound circuit, the signal biography is put chip IC ₆Sheffer stroke gate connects the d type flip flop chip IC after the upset ₇Pulse input and D input end, at the lasting noble potential of 5 pin output, be connected to chip IC ₈1 pin since this moment chip IC ₈Two input ends be noble potential, 3 pin output terminals are electronegative potential, end B point electronegative potential, controllable silicon D ₅Close the door, disconnect the bridge rectifier loop, output 220V exchanges end and closes.

When closing out-put supply, if human body pyroelectricity sensor RT senses people's activity, chip IC ₁9 pin be electronegative potential, pass through chip IC ₈Make triode Q ₁, controllable silicon D ₅, bridge rectification conducting, restore electricity.When counting down if human body pyroelectricity sensor RT senses the people when movable, chip IC ₁13 pin noble potentials, when restoring electricity, numeral shows zero clearing.

This device roughly divides six part element circuits, the D of human body pyroelectricity sensor RT, G termination 5V direct supply, and the S end passes through chip IC for signal output ₁Two Sheffer stroke gates can obtain opposite electric signal at 10 and 13 pin, the triggering following circuit simultaneously.Chip IC ₂Enough become multi-resonant oscillating circuit with peripheral cell, the input of 4 pin, 3 pin are exported, and the pulse signal of certain frequency is provided for counter.The digital demonstration adopted two down counters, unites and shows two demonstrations, the input of 7 pin, the output of 11 pin.Chip IC ₅Be sound circuit, 24 pin connect broadcast and trigger, and 14,16 pin connect loudspeaker.

Chip IC ₆, IC ₈Input signal is carried out non-upset IC ₇Be d type flip flop, trigger end 2 and clock pulse input terminal fetch simultaneously from IC ₆Pulse signal, can guarantee IC like this ₆A positive pulse, D end reaches lasting noble potential with obtaining trigger pip at 5 pin in the time of rising edge.Triode Q in the circuit ₁And D ₅Be the key element of electronic switching circuit, triode Q ₁Conducting between collector and emitter, can be considered small resistor or have only the noble potential of tube voltage drop, by the time can be considered big resistance or open circuit, controllable silicon D between collector and emitter ₅Come to have played the effect of microelectronic switch for the conducting " igniting " of big electric current by little electric current.IC ₉Be the 5V integrated package of pressure-stabilizing, shunt capacitance can fully filter alternating component respectively before and after it, makes direct supply better, and the circuit working of power supply is more stable.R ₅With chip IC ₅Series connection is for the short member of the pulsating direct current after bridge rectification power supply dividing potential drop, in order to the assurance chip IC ₉Input end 1 pin voltage in allowed limits.Controllable silicon D ₅Be connected in the pulsating direct current loop, because size of current is easy to control the open and close door constantly changing and the higher per second of frequency 120 times.

This device is connected electric power plug socket and wall power middle (corresponding conversion jack is arranged), will links to each other with this device, the affix of built-in human body pyroelectricity infrared sensor RT gets final product in the zone that is placed on desk or has personnel to work.
