Description of drawings
By below in conjunction with the description of accompanying drawing to preferred embodiment of the present invention, can further understand purpose of the present invention, feature and advantage, wherein:
Fig. 1 is the schematic circuit diagram of the auto-safety mechanism of this practicality.
The specific embodiment
Auto-safety mechanism of the present utility model comprises distance measuring unit, the flue gas monitoring unit, the body inclination monitoring means, the radiofrequency signal receiving element, emission of radio frequency signals device and phonic warning chip, as shown in Figure 1, distance measuring unit comprises MA integrative ultrasonic wave sensor and LM3914 IC chip, the output terminals A of MA integrative ultrasonic wave sensor links to each other through the signal input pin of rheostat with the LM3914 IC chip, and each output pin 1～9 of LM3914 IC chip links to each other with the input pin 1～9 of phonic warning chip with collecting electrode through the basis set of aerotron.Reasonablely be, in above-mentioned auto-safety mechanism, comprise that further 4017 IC chips are used for distance and select, its input pin links to each other with range selection switch K3, and output pin links to each other through the output pin of auxiliary circuit with the LM3914 IC chip.Ultrasonic transduter can be installed in the tailstock, and when the distance of the tailstock and obstacle during less than the distance selective value, ultrasonic transduter will detect the signal of reflection, provide the phonic warning chip after amplifying through the LM3914 chip.
The flue gas monitoring unit comprises flue gas sensor QM-N10 and the signal amplification circuit chip 555 that links to each other with the flue gas sensor through auxiliary circuit, and the output pin of signal amplification circuit chip 555 links to each other through the input pin of resistance with the phonic warning chip.When smog occurring in the compartment, the light patch of flue gas sensor is blocked, and flip chip 555 produces alerting signal, and this signal is output to the phonic warning chip, thereby sends voice suggestion.Voice content comprises " 50 meters ", " 40 meters ", " 30 meters ", " 20 meters ", " 10 meters ", " 7 meters ", " 4 meters ", " 2 meters ", " 1 meter ", " pernicious gas exceeds standard, woulds you please take measures ", " medical truck chimes of doom " and contents such as " welcoming you to come " at once.
The body inclination monitoring means comprises mercury switch K5, and the one end is connected to power supply through an aerotron basis set and collecting electrode, and the other end is connected to the phonic warning chip.When the vehicle body knockdown or when overturning, therefore the mercury switch closure will produce an energizing signal, and this energizing signal is imported phonic warning chip, thereby sends voice suggestion.
