The specific embodiment
The control circuit of a kind of intelligent braking system; Comprise that micro controller system, system power supply, temperature compensation unit, LCD display unit, braking circuit unit, ultrasonic transmitting element, super sonic receiving element, alarm unit, button are provided with the unit; Said system power supply is the total system power supply; Detected temperature signal is given the P3.4 pin of micro controller system in the unit of said temperature compensating; Said LCD display unit is connected with micro controller system, and said brake unit connects the P2.1 pin of micro controller system, and said ultrasonic transmitting element is launched ultrasonic signal after receiving the control signal of P2.2 pin of micro controller system; Said super sonic receiving element sends signal the P2.0 pin of the P3.2 pin of micro controller system, said alarm unit and micro controller system to, and said button is provided with the P1.0-P1.3 that the unit connects micro controller system.
Said micro controller system is AT89C51.
The model of the ultrasonic probe of said ultrasonic transmitting element is selected CSB40T for use, and the model of the super sonic receiving transducer of super sonic receiving element is selected CSB40R for use, and control chip adopts CX20106A.Ultrasonic probe must adopt and the cooresponding model of transmitting probe, and it is consistent mainly to be that frequency is wanted, otherwise influences reception even can't receive because of producing to resonate.
It is LCD1602 that said display module is selected model for use, is used for display system information, can obstacle be come out from the distance indication of car.
The temperature sensor model of said temperature compensation unit is selected DS18B20 for use.
Said push-button unit is used for on-off system and the safety arrestment braking distance is set.As big at vehicle flowrate at ordinary times, in the time of low speed driving, spacing is very little between car and the car; This time can shutdown system, so that cruising, and in running on expressway; Vehicle Speed is fast; Spacing is big between car and the car, and can open system this time, and a safety guard-safeguard is provided for running at high speed.
