Employing is controlled tail-light based on the circuit control mode of EDA system, the timely problem such as trigger circuit source switch in case overcome that the aging or contact problems that cause because of mechanical vibration of traditional machinery and pure circuit control mode circuit and mechanical element are out of shape.
Description of drawings
Fig. 1 is the systematic schematic diagram of the utility model.
The specific embodiment
A kind of automobile tail light circuit; Its composition comprises micro controller system, micro controller system download circuit, reset circuit, warning circuit, oscillating circuit, direction indicating circuit, key control circuit, it is characterized in that: 1,3,9 pin of the download circuit of said micro controller system are connected with P15, P16, the P17 pin of micro controller system respectively; Said reset circuit output stage is connected with the RESET pin of micro controller system; The base input end of the aerotron of said warning is connected with the P34 pin of micro controller system; Said oscillating circuit is connected with XTAL1, XTAL2 pin; Said direction indicating circuit is connected with the P0.0-P0.5 pin of micro controller system; Said key control circuit is connected with the P30-P33 pin of micro controller system.
Said micro controller system adopts AT89S51.
The chip that said reset circuit adopts is AT89S.
Reset circuit
When VCC powered on, the C3 charging voltage occurred on resistance R 2, make micro controller system reset; Behind several milliseconds, C3 is full of, and the electric current on the resistance R 2 reduces to zero, makes micro controller system get into mode of operation; Device work is pressed S, the C3 discharge, and S looses one's grip, and C3 charges again, on resistance R 2, voltage occurs, makes micro controller system reset, and behind several milliseconds, micro controller system gets into mode of operation.
Warning circuit
Add the 3-15V DC operation at the loud speaker two pins, just can produce the buzzing concussion sound equipment about 3KHZ.The voltage-type buzzer phone is simple in structure, and little power consumption is more suitable in SCM system, using.Piezo buzzer needs the drive current of about 10MA, can drive at the driving circuit that certain port connects an aerotron and resistance composition; As shown in Figure 1, P34 connects the base input end of aerotron among the figure, when P1.0 output high level " 1 "; The aerotron conducting, buzzer phone energising pronunciation is when P1.0 output low level " 0 "; Aerotron ends, and buzzer phone stops pronunciation.
The direction indicating circuit
When right-hand corner, D1 can light; During right-hand corner, D6 can light; During sudden stop, D2 and D5 together with the time light; During night running, D3, D4 can light simultaneously; So select coloured LED lamp, be convenient to the observation of pedestrian and other vehicles.
Key control circuit
S1 is the emergency brake button, and S2 is the night running button, and S3 is the turnon left button, and S4 is the right-hand corner button; The high-low level of the I/O that micro controller system is connected at 4 buttons of the scanning that does not stop, after a button in 4 buttons went down, micro controller system can confirm which presses down earlier; When not having button to go down, these 4 I/O mouths all are high level, and after some pressing down, the I/O mouth pin that can be connected with this button becomes low level.
