摘要
研制了一种智能移动预警网络装置,该装置集移动通信与预警功能于一体;分析了装置的工作原理,设计了主装置和从装置,重点介绍了基于NiosII的复位电路的设计、实时时钟模块的设计、报警模块设计、PWM模块设计以及电源模块设计等;实验结果表明系统具有传输速率2Mbps、主从装置间最大报警距离达到50m、发射功率小、可靠性高等优点,具有较高的应用与推广价值。
A sort of intelligence mobile alarm network device was designed. The device integrated the mobile communications and alarm functions. Working principle of device was analyzed and the master device and the slave device were designed. This paper mainly introduced the design of reset model, the design of real time clock module, the design of alarm module, the design of PWM module and power supply module based on Nios Ⅱ and so on. Experiments showed that this system had advantages of 2M bps transmission rate, 50 meter alarm dis tance between the master device and the slave device, low transmit power and high reliability. It possessed high application value and promo- ting value
