Study Limitations Grace High Road Anti-collision Alarm Device

In view of the present situation of super wide super high vehicle often lead to roadinfrastructure damage or casualties and other major traffic accidents, illustrates thenecessity, vehicle width limit high limit, the limit of grace high device and defects ofcommon road. On this basis, the development of a new restrictions grace high roadanti-collision alarm device of the purpose and significance of.In the analysis of limit grace high road anti-collision device on the functionrequirement, design scheme of several high device limit of grace, and throughcomparison and evaluation of the implementation plan, determine the overall designscheme of the restrictions grace high road anti-collision device.According to the overall design program restrictions grace high road anti-collisiondevice, magnetic, optical and fiber by comparing three kinds of sensor performance andprice, the selected vehicle ultra wide high detection device--photoelectric sensor; theMitsubishi FX2n programmable logic controller, design the test from the vehicle ultrawide high to measurement and control system of sound, light, screen alarm control, thecorresponding software is compiled; and then, designs the hardware and software of theroad anti-collision device in a vehicle alarm system, wide high, to realize synchronousalarm buzzer, alarm lights and alarm screen.Finally, according to section of Xiangyang bridge in Suzhou city is often the car hita bridge or limit high pole caused a traffic accident phenomenon, this paper designs aconsistent with anti-collision devices the use of sections, gives the calculation methodof mechanical structure, anti-collision device installation location and distance etc..Using this device, can effectively remind drivers of vehicles to avoid traffic accidents.
