The specific embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of automobile anti-rear end collision device, this device comprises surveys sensing device (1), described detection sensing device (1) is delivered to primary processor (4) by input circuit (2), A/D and D/A change-over circuit (3) with signal, primary processor (4) is delivered to brake control system (6) and throttle control system (7) with control signal by A/D and D/A change-over circuit (3), output circuit (5), and shows signal is delivered to display circuit (8); Described detection sensing device (1) comprises that spacing sensor, car speed sensor, car are to sensor; Described primary processor (4) adopts the 89C52 system micro controller system of INTER company; Adopt asynchronous serial communication interface RS-232C (10) between described detection sensing device (1) and the primary processor (4); Be connected with brake oil cylinder (9) in the described brake control system (6), brake oil cylinder (9) comprises cylinder body (91), the sidewall that the oil outlet end of cylinder body (91) is provided with oil outlet (92), oil inlet end is provided with oil inlet (93), oil outlet end in the cylinder body (91) is provided with spring (94), oil inlet end is provided with piston (95), piston (95) is provided with J-shaped oilhole (96), oil inlet (93) is communicated with oil outlet (92), and cylinder body (91) is provided with magnet coil (97) in the outer wall of oil outlet end.
Under the normal circumstances, brake fluid line forms path, do not influence conventional brake, when running into obstacle, send instruction by primary processor (4), magnet coil (97) is received the instruction back and is formed magnetic field, inhalation-activated piston (95) is closed oil inlet (93), and brake solution forms closed cycle, strength by oil pressure is started working the ABS system, reaches the purpose of braking brake.
The utility model is employed laser detector aspect range finding, broken the notion of original laser ranging, solve it and penetrated hypodynamic weakness, employing is upgraded, task is found range in higher technology implementation, the information that this instrument can change obstacle in the place ahead exactly, through certain converting means, turn into corresponding data-signal.Simultaneously, the utility model also operating speed sensor (12), direction sensor (13) waits the travel situations of detecting self vehicle, and these information are delivered among the device.
Primary processor of the present utility model (4) adopts the 89C52 system micro controller system of INTER company, the CHMOS technological design of its low-power consumption, and remarkable serviceability can satisfy the various demands of device fully.
In order organically to couple together primary processor (4), external device, measuring instrument easily, constitute a failure-free measuring and controlling, the utility model adopts asynchronous serial communication to meet product RS-232C, because 89C52 micro controller system input and output level is a Transistor-Transistor Logic level, inconsistent with the electrical code of RS-232C standard serial interface, therefore, use the RS-232C chip to carry out level conversion.
Like this, the signal that process detects and change is sent is to A/D converter (3), in order to satisfy accuracy requirement, the A/D converter that the utility model adopts, it is eight of a kind of low-power consumption force-type A/D converter one by one, because the speed of a motor vehicle is higher, changing apart from parameter of recording is also inevitable very fast, so post-sampling in addition, lock-out circuit, can when starting the A/D conversion, keep incoming signal, thereby can avoid A/D to change the transformed error that brings aperture time.
