摘　　要：针对当前监控系统存在接入传感器的数量受限、成本过高等问题,笔者采用单元分时的策略,利用编码器对其进行编码,使传感器产生触发电平信号,通过触发电平信号切换中央处理器,控制不同通讯模块的数据传输,保证4G频段在需要时才占用,从而提高NB-IOT模块通信的使用时间,降低整个监控系统的功耗,提高传感器的接入数量;且在中央处理器中增加监测功能,当检测到震动探测器的信号时,实时将摄像头的视频信息上传至服务器,降低磁盘空间的占用.实验结果表明,改进后的系统简单可靠,易于实现,提高了磁盘空间利用率,降低生产成本.In view of the problems of limited number and high cost of access sensors in the current monitoring system, the author adopts the unit time-sharing strategy and encodes it with encoder to generate trigger level signal in the sensor, switch the central processing unit through the trigger level signal, and controls the data transmission of different communication modules to ensure that the 4G frequency band is occupied when needed, so as to improve the service time of NB-IOT module communication, reduce the power consumption of the whole monitoring system and improve the access number of sensors. In addition, the monitoring function is added in the CPU. When the signal of the vibration detector is detected, the video information of the camera is uploaded to the server in real time to reduce the occupation of disk space. The experimental results show that the improved system is simple, reliable and easy to implement, which improves the utilization of disk space and reduces the production cost.
