Accompanying drawing explanation
Fig. 1 is safe early warning control system theory diagram of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot Conjunction is specifically illustrating, and the present invention is expanded on further.
When being embodied as, in conjunction with Fig. 1, a kind of vehicle active safety pre-alarming control system, including FPGA, controller, speed Sensor, rotation direction sensor, throttle sensor, braking sensor, throttle sensor, LCD MODULE, sound and light alarm mould Block, brake hard module, the first ccd video camera, the second ccd video camera, A/D sample.Vehicle speed sensor, rotation direction sensor, oil Door sensor, braking sensor, throttle sensor, LCD MODULE, sound and light alarm module, brake hard module are for controlling The peripheral circuit of device is connected with controller respectively.First ccd video camera, the second ccd video camera through A/D sample after with FPGA phase Even.FPGA is in communication with each other with controller by CAN.FPGA is EP1C12Q240C8.Controller is that ARM11, ARM11 are ARM1156T2.LCD MODULE is liquid crystal display, and liquid crystal display is TFT LCD.
First ccd video camera, the second ccd video camera are monitored in real time, the traffic information in collection vehicle traveling front, and Sampled by A/D, convert analog signals into digital signal and send FPGA, FPGA to and carry out image procossing, improve picture quality, Improving the visual effect of people, finally identifying is the barriers such as vehicles or pedestrians, and FPGA will identify that it is the barriers such as vehicles or pedestrians Thing information is hindered to be transferred to controller by CAN.The information that FPGA transmits is demonstrated in LCD MODULE by controller Coming, both extended the visual field of driver, dynamic detects traffic information timely again, ensures driving safety.Sound and light alarm module It is when system judges have barrier to occur and it is smaller than safety distance with car traveling with emergency brake module, The corresponding measure by acoustooptic form driver reported to the police or take.Vehicle speed sensor, rotation direction sensor, throttle sense Device, braking sensor, throttle sensor obtain the speed of vehicle, wheel steering, throttle, braking, throttle opening respectively Deng corresponding information, and above-mentioned information being passed to controller, after controller receives the information of each sensor acquisition, controller enters The operations such as the distance display of row vehicle follow gallop, speed, sound and light alarm, auxiliary braking and brake.When sound and light alarm module receives control During the alarm control signal that device transmits, driver will be reminded to note danger ahead by sound and light alarm immediately, and take brake measure.
