The specific embodiment
Referring to Fig. 1, intelligent vehicle of the present utility model the place ahead obstacle detection system, comprise intelligent vehicle, power management module, detection of obstacles module, steering wheel steering module and motor drive module, power management module, detection of obstacles module and steering wheel steering module also link to each other with micro controller system respectively, motor drive module one end links to each other with micro controller system, and the other end links to each other with DC machine.
As shown in Figure 2, the power management module of intelligent vehicle is fixedly mounted on the intelligent car body and provides electric energy for micro controller system, drive motor and steering engine.Drive motor is installed in the rear portion of car, drives the rear axle of intelligent vehicle.Steering engine is connected with front-wheel by bindiny mechanism, and is subjected to the micro controller system signal control and the function that realizes turning to.Homemade circuit card is welded with the circuit of total system, and it is fixed on the vehicle body, is welded with various terminal and is connected with power supply, micro controller system, motor, steering wheel etc.The used Photoelectric infrared switch of detecting module is fixedly mounted on the car forefront, and is installed on the longitudinal centerline of car, is convenient to the detection that detecting module more accurately carries out obstacle like this.
Shown in Figure 3, when the 7.2V electricity in the intelligent vehicle power module is supplied with motor, also need big electric current, IRF3703/IRL3803 can supply with big electric current of motor.With this requirement of satisfying the intelligent vehicle dynamic property, intelligent vehicle is stablized at a high speed travelled.
Shown in Figure 4, this figure is the infrared ray receiver/transmitter circuit figure of intelligent vehicle detecting module acquisition sensor, obstacle is given receiving end the infrared reflection of launching when obstacle, according to the ultrared power of emission meeting, the voltage tester end reflects the voltage that is directly proportional with arrival current, through after the processing of circuit shown in Figure 4 it is sent into the I/O mouth of micro controller system then.When obstacle, corresponding mouth becomes high level, and micro controller system reads the state of each mouthful by inquiry mode, calls different functions, turns to finish accordingly.
Shown in Figure 5, the electric energy of intelligence is from the Ni-Cd battery of 7.2V, a 1500mAh, but the micro controller system normal operation needs the burning voltage of 5V, in order to make the steering wheel rotating property relatively good, the voltage of 5V need be provided for steering wheel, and the operating voltage of infrared detector also is 5V, so need change the cell pressure of 7.2V, to satisfy the voltage request of each several part, this conversion realizes by low pressure voltage stabilizing chip 7805.
