摘要:
针对复杂场景下对监测设备的较高要求,设计了一种通用型的无线监测系统。 系统中的每一个传感节点基于 433MHz ISM 射频频段来完成数据的无线收发,并且在节点与节点之间设计了点对多点的自组网方法。 收发节点先由 Cortex-
M3 内核的单片机控制收发,然后把数据传入到嵌有 OpenWrt 开源系统的网关中,在网关中完成串口数据与 Socket 数据的相互转换,最后通过 WIFI 技术把采集数据传入 PC 端进行监测与反向控制,并在开源视频服务器软件 MJPG-streamer 的框架结构下实现视频采集。 客户端软件采用 C#语言进行编写,除了简单的界面显示之外,主要完成网络通信、数据处理、反向控制和监控界面显示等功能,使该系统具有较好的监测功能以及人机互动功能。 整个系统的功耗较低、便携性较高、实用性强,可实现多点监测。
Abstract:
Aiming at the high demand of the monitoring equipment in the complex scene,an universal wireless monitoring system is designed. Each sensor node in the wireless monitoring system completes the transmitting and receiving of data through 433 MHz ISM band radio frequency,and a point-to-multipoint ad hoc network method is used among these nodes. First of all,data in the transceiver node controlled by SCM (Single Chip Micyoco) with the Cortex-M3 microcontroller as its core is transmitted to the gateway embedded Open-Wrt open-source system. Then,the interconversion between serial data and Socket data is carried out in the gateway. Finally,the collected
data is ultimately transmitted to PC terminal for monitoring and reverse control by WIFI technology. In addition,the video capture is actualized in the MJPG-streamer framework,an open source video server software. The client software written by C#,in addition to simple interface display,is mainly for network communication,data processing,reverse control and monitoring interface display. Therefore,the system has better functions of monitoring and human-computer interaction,with low-power consumption,strong portability and high practicability,which can realize the multi-point monitoring.
