It is placed with the SD card for storing alert help voice in the voice broadcast module 6, when rollover thing occurs for automobile
After therefore, voice broadcast module 6 is triggered, and active small speaker 8 plays alert help voice.
The double-shaft tilt angle sensor 3 is SCA60C module, can be realized the inspection of left and right 0-180 degree range of tilt angles
It surveys.
Latitude and longitude information and text the relief information that GPS module 4 is transmitted are sent to specified number by the gsm module 5
Code, it is contemplated that the unpredictability of accident, gsm module 5 realize that the more human hairs of above- mentioned information are sent.
The working principle of the utility model are as follows:
Overall work principle: the dip angle signal analog voltage output of double-shaft tilt angle sensor 3 is (0-180 ° of corresponding 0.5-
4.5V), 90 ° -180 ° of inclination angle is set as the threshold range size of triggering (double-shaft tilt angle sensor 3 exports electricity at this time by the design
Pressure range size is 2-4.5V, and 2 acquisition voltage range size of STM32 single-chip microcontroller is 1.4-3.3V after electric resistance partial pressure), pass through
Collected voltage analog is converted to digital quantity by the included A/D module of STM32 single-chip microcontroller 2, if STM32 single-chip microcontroller 2 acquires
The voltage value arrived is more than or equal to 1.4V (i.e. automobile inclination angle be more than or equal to 90 °), and gsm module 5 is by the longitude and latitude in GPS module 4 at this time
Degree information and the help information of editor are sent to specified people, while voice broadcast module 6 is triggered, active small speaker 8 into
Row loop play is previously stored in the voice help information in SD card.
Gsm module 5 transmits latitude and longitude information principle: referring to Fig. 2, geographic position data packet is passed through serial ports 1 by GPS module 4
It is sent on STM32 single-chip microcontroller 2, data are placed in buffer zone by STM32 single-chip microcontroller 2, due to before not handled
Storage in the buffer be a big string byte stream, therefore, it is necessary to by program by the information of each field from caching byte stream
It extracts, converts it into and be of practical significance, the location information data that are used for decision of the senior level.Therefore, STM32 monolithic
The data received are carried out the decoding of NEMA format by machine 2, and decoded data are sent to gsm module 5, GSM mould by serial ports 2
Decoded latitude and longitude information is sent to specified cell-phone number by block 5, so that the positioning of accident spot position is completed, in order to implement
It rescues as early as possible.
