传感器技术作为信息科学的一个重要分支与计算机技术、自动控制和通信技术等一起构成了信息技术的完整科学。本设计运用单片机与传感器技术,把智能检测与自动控制相结合,实现独立的告诉单行道智能测速报警系统。我们制动控制模块选用的德州仪器的MSP430G2553超低功耗十六位单片机,单片机对传感器的输出信号进行处理。热释电模块我们选用HC—SR501,配合BIS0001芯片,把探头检测到的信号转化为数字信号给单片机。激光测速模块选用光电二极管配合激光头,再利用单片机处理触发信号利用公式V=S/t求出速度。
As an important branch of information science, sensor technology, together with computer technology, automatic control and communication technology, forms the complete science of information technology. The design uses single-chip and sensor technology, the combination of intelligent detection and automatic control, to achieve an independent one-way road to tell intelligent speed alarm system. We selected brake control module Texas Instruments MSP430G2553 ultra-low power 16-bit microcontroller, the microcontroller output signal processing. Pyroelectric module we choose HC-SR501, with the BIS0001 chip, the probe detects the signal into a digital signal to the microcontroller. Laser speed module optoelectronic diode with the laser head, and then use the microcontroller trigger signal processing using the formula V = S / t speed.
