摘要
通过低通滤波器对MMA7360加速度传感器信号进行处理,获取准确的铁鞋的位移信息,并将此信息经微处理器处理,根据处理的结果来判断铁鞋所处的状态,当铁鞋有移动时,微处理器将通过GSM模块实现短信、电话二种不同的报警方式。文章介绍了系统的各个功能模块,并给出了相应的软件流程和算法,实验表明,系统稳定性好,有效的提高了工作效率,极大程度上减小了安全隐患。
By processing the signal got from the MMA7360 acceleration sensor by low-pass filter, accurate displacement of the iron shoes can be obtained, according to the results, the state of the iron shoes can be determined, when the iron shoes have a accu- rate displacement ,the MCU alarms through telephone and GSM. The article describes the various functional modules of the system, and gives the corresponding software processes and algorithms, experiments show that the system has good stability and improve the work efficiency to a great extent reducing the security risks.
