The utility model detects side-marker lamp LAMP signals, key position signal ACC by input terminal CON1, if ACC without Signal, continue to detect side-marker lamp signal, side-marker lamp no signal, present apparatus alarm free, automatically power off, not battery consumption electricity, If any signal, daytime prompts car owner to close side-marker lamp jointly by alarm with former car loudspeaker, and night can only pass through high brightness report Alert device is prompted.

Side-marker lamp LAMP, key switch ACC are detected by input terminal CON1, detection exists when ACC signals, all the way signal NAND gate is inputed to by diode D4 to detection resistance R3 and pull down resistor R4 to system power supply, another way by diode D2 Logic chip IC1 1 pin, 2 pin, NAND gate logic chip IC1 1 pin, 2 pin are that high level its 3 pin after logical operation is defeated Go out low level.Because NAND gate logic chip IC1 3 pin and 5 pin are electrically connected with, NAND gate logic chip IC1 5 pin input is low Level, no matter at this moment which kind of state of NAND gate logic chip IC1 6 pin, after logical operation, its 4 pin can only export high electricity It is flat.Because NAND gate logic chip IC1 4 pin and the pin of 8 pin 9 are electrically connected with, NAND gate logic chip IC1 8 pin, the input of 9 pin High level, its 10 pin exports low level after logic and operation, due to NAND gate logic chip IC1 10 pin and clock chip IC2 4 pin are electrically connected with, clock chip IC2 4 pin input low levels.

The 4 pin input low levels of the clock chip IC2, clock chip IC2 are set, its 3 pin output low level, due to Clock chip IC2 3 pin are electrically connected with buzzer U2, and buzzer U2 does not work.Again because clock chip IC2 3 pin with it is non- 12 pin of gate logic chip IC 1 are electrically connected with, NAND gate logic chip IC1 12 pin input low levels, similarly NAND gate logic No matter its 10 pin of which kind of state of 13 pin of chip IC 1 can only export high level.NAND gate logic chip IC1 10 pin pass through driving Resistance R10 and power amplification triode Q1 is electrically connected with, and buzzer Q1 cut-offs, warning output relay K1 disconnects.

Side-marker lamp LAMP, key switch ACC are detected by input terminal CON1, detection is not present when ACC signals, side-marker lamp In the presence of LAMP signals, signal passes through diode D3 to detection resistance R2 by diode D1 to system power supply, another way all the way NAND gate logic chip IC1 6 pin are inputed to pull down resistor R5, NAND gate logic chip IC1 6 pin are high level, at this moment After there is no ACC signals, key switch ACC to close, due to having the 1 of pull down resistor R4 presence NAND gate logic chip IC1 Pin, 2 pin input low levels, after logical operation, its 3 pin output high level, due to NAND gate logic chip IC1 3 pin and 5 Pin is electrically connected with, NAND gate logic chip IC1 5 pin input high levels, passes through the low electricity of its 3 pin output after logical operation It is flat.Because NAND gate logic chip IC1 3 pin and 5 pin are electrically connected with, NOT gate logic chip IC1 6 pin are high level, are passed through After logical operation, its 4 pin can only export low level.Because NAND gate logic chip IC1 4 pin and 8 pin, 9 pin are electrically connected with, with NOT gate logic chip IC1 8 pin, 9 pin input low levels, its 10 pin exports high level after logic and operation.Due to it is non- 10 pin of gate logic chip IC 1 are electrically connected with clock chip IC2 4 pin, clock chip IC2 4 pin input high levels, clock The timer of chip IC 2 starts, clock chip IC2 3 pin output 0.5HZ pulse, due to clock chip IC2 3 pin and buzzing Device U2 is electrically connected with, and buzzer U2 sends 0.5Hz alarm signals.Again because clock chip IC2 3 pin NAND gate logic chips IC1 12 pin are electrically connected with, NAND gate logic chip IC1 12 pin input 0.5HZ pulse, NAND gate logic chip IC1's 13 pin are by pull-up resistor R8, the electric R9 of drop-down, photo resistance RG, and when daylight is strong, photo resistance RG resistances are low, NAND gate Logic chip IC1 13 pin input high levels, NAND gate logic chip IC1 10 pin output 0.5HZ pulse, NAND gate logic For 10 pin of chip IC 1 by driving resistance R10 and power amplification triode Q1 to be electrically connected with, triode Q1 is also with 0.5HZ's Pulse frequency switchs, driving warning output relay K1 0.5Hz frequency alarm outputs.When night, light was weaker, photo resistance RG resistances become big, and NAND gate logic chip IC1 13 pin make NAND gate by pull-up resistor R8, the electric R9 of drop-down, photo resistance RG Logic chip IC1 13 pin are low level, no matter which kind of state of NAND gate logic chip IC1 12 pin, its 10 pin can only export High level, NAND gate logic chip IC1 10 pin are by driving resistance R10 and power amplification triode Q1 to be electrically connected with, three poles Pipe Q1 ends, and warning output relay K1 disconnects, and only can utilize buzzer U2 alarms at night.

Side-marker lamp LAMP, key switch ACC are detected by input terminal CON1, when ACC signals, side-marker lamp LAMP signals all In the absence of when, device is stopped because of non-transformer, does not consume battery electric quantity.
