Fig. 1 a, Fig. 2 a are the design's schematic diagram.

Below in conjunction with accompanying drawing the design is described in detail.

Rectification circuit D in two signal input circuits _1-4, D _5-8Respectively be connected to a relay J ₁, J ₂, be subjected to J ₁The pulsing circuit (corresponding with red light) of control is by R ₇, C ₃, D ₁₅Constitute J ₁Normally closed contact insert R ₇, C ₃In the capacitance-resistance loop, diode D ₁₅Negative pole insert the capacitance-resistance loop, positive pole meets main triode BG in the start-up circuit ₁Base stage, BG ₁Grounded emitter, collector is through diode D ₁₃Access is by triode BG ₃The on-off circuit of forming, secondary triode BG in the start-up circuit ₂Base stage pass through resistance R ₆With main triode BG ₁Collector connect BG ₂Collector one tunnel through capacitor C ₂Positive pole and BG ₁Base stage connect, another road is through resistance R ₅Insert power supply, capacitor C ₂Negative pole through resistance R ₄Insert power supply, by R ₄, C ₂Control BG ₁Conducting or closing time.Equally, with the corresponding J that is subjected to of green light ₂The pulsing circuit of control is by R ₈, C ₄, D ₁₆, relay J ₂Normally closed contact insert R ₈, C ₄In the capacitance-resistance loop, diode D ₁₆Negative pole insert described capacitance-resistance loop, positive pole meets BG ₁Base stage.Triode BG in the on-off circuit ₃Base stage and diode D ₃Negative pole connect, grounded emitter, collector is connected to relay J ₃, J ₃Normally opened contact insert speech synthesizers through circuit of three-terminal voltage-stabilizing integrated 7805.Speech synthesizer can adopt the cassette player system of cyclic tape loop playback also can adopt the language integrated circuit, the design has adopted the cassette player system of two sound channels, after cyclic tape changes, through the preposition amplification in the cassette player system, process connects two capacitor C of serial connection to the signal of R sound channel or L sound channel again by magnetic head ₁₃, C ₁₄Send into the note amplifier of forming by integrated circuit SL34, and then in loudspeaker, send and red, the corresponding sound of green light.The signal that 8 pin of integrated circuit SL34 come out is again through D ₁₇, D ₁₈, C ₁₅Rectification send into by prime BG ₅, back level BG ₄Form prime BG in the ON-OFF control circuit ₅Base stage, prime triode BG ₅Grounded emitter, collector one tunnel meets back level triode BG ₄Base stage, resistance R is passed through on another road ₉Insert the input end of sound generator, back level triode BG ₄Grounded emitter, collector one tunnel is through diode D ₁₄Base stage and the triode BG in the on-off circuit ₃Base stage connect, another road is through resistance R ₁₀With J ₃Normally opened contact connect.

Under the virgin state, power supply passes through relay J behind transformer B step-down rectifier ₁, J ₂Normally closed contact J _1-1, J _1-2To capacitor C ₃, C ₄Charging, capacitor C ₂Pass through R ₅, make C ₂The voltage at two ends is near supply voltage, and BG ₁Pass through resistance R ₄Obtain enough base currents and conducting makes BG ₁Collector potential be electronegative potential, and then make BG ₂, BG ₃All be in cut-off state, because BG ₃End J ₃Be failure to actuate, complete machine is in the shutdown waiting status.

When red light is bright, by rectification circuit D _1-4Rectification, resistance R ₁Step-down is at J ₁Two ends obtain 12 volts of voltages of a direct current, make J ₁Adhesive, its normally closed contact J _1-1Disconnect normally opened contact J _1-2Conducting, J _1-1The moment of conducting, capacitor C ₃Discharge is by C ₃, D ₁₅, R ₇The pulsing circuit of forming produces a negative pulse, makes BG ₁By conducting state, become cut-off state, BG ₁Collector become noble potential by electronegative potential, diode D ₁₃Conducting makes BG ₃Become conducting state by cut-off state, relay J ₃Adhesive, normally opened contact J _3-1Closure makes the loop playback system works, and then sends the sound of " be red light now, Please Wait " on loudspeaker Y.

Start-up circuit can make playback system move for 2 seconds, by R ₄=10Kn, C ₂=220uF decision, the cyclic tape length overall is 5 seconds, wherein, starts, stops each 1 second, one section speech is 3 seconds.BG ₁After the conducting, make BG ₂Become conducting state by cut-off state, because capacitor C ₂The voltage at two ends can not suddenly change, so C ₂The C terminal potential can not suddenly change, the current potential of C end becomes low electricity by original high-voltage, this electronegative potential can make BG ₁Continue the remain off state, along with C ₂Pass through R ₄, BG ₂And the discharge of power supply, the C terminal potential rises gradually, can make BG when reaching ₁During conducting, BG ₂End, start-up circuit work finishes, and waits for starting next time.

Behind the circuit start, the magnetic signal of R sound channel becomes electric signal through magnetic head on the cyclic tape, passes through J _1-2After audio frequency amplifies in cassette player, again through capacitance C ₁₃, C ₁₄Send into integrated circuit SL34 and carry out power amplification, on loudspeaker Y, pronounce at last.

When sound, the AC signal at loudspeaker Y two ends is through D ₁₇, D ₁₈, C ₁₅Rectification after at BG ₅Base stage obtain one and can make BG ₅The current potential of conducting, BG ₅Conducting make BG ₄Current collection noble potential very, this noble potential passes through D ₁₄Continue to keep BG ₃Conducting, J ₃Continue adhesive, the loop playback system continues operation, and loudspeaker Y continues sounding.After one section on cyclic tape R sound channel words " be red light now, Please Wait " have been said, BG ₅Base potential become electronegative potential by noble potential, BG ₅End BG ₅Collector potential become noble potential, BG ₄Conducting makes BG ₄Collector potential become electronegative potential, make BG ₃End J _3-1Disconnect, system-down waits for that green light restarts operation when bright again, and when amber light was bright, this machine still in a state of nature.

When green light is bright, J ₂Adhesive, its normally closed contact J _2-1Disconnect normally opened contact J _2-2Conducting is by C ₄, R ₈, D ₁₆The pulsing circuit of forming produces a negative pulse, BG ₁Become cut-off state by conducting state, later working condition is the same when bright with above-mentioned red light, and just loudspeaker Y sends is the sound that one section word on the L sound channel on the cyclic tape " are green light now, would you please mind how you go ".

Magnetic signal track part on the cyclic tape is: the R sound channel " is red light now, woulds you please marquis slightly "; L sound channel: " be green light now, would you please mind how you go ".These two words are to be that parallel arranged on 5 seconds the tape in length.Wherein, 3 seconds for signaling zone, 2 seconds for clear area, clear area be used for the system that realizes starting and stop.

The utility model also can directly link to each other three red, yellow, green light external connections except that can using separately with the signal main frame, make this machine can with the synchronous operation of signal main frame.

The utility model is owing to adopted speech synthesizer and corresponding circuit, and available language points out people to note traffic safety.
