基于ZigBee与NB-IoT技术的白蚁侦测系统设计

Design of termite detection system based on ZigBee and NB⁃IoT technology

白蚁是一种破坏性极大的世界性害虫,其危害范围十分广泛,包括房屋建筑、交通设施、江河堤坝等都是它的危害对象。这些危害不易被人察觉,但是一经发现往往后果已十分严重。现有的白蚁防治手段主要是通过大范围喷药来实现的,这种方式不仅效率低、成本高,还会对环境造成大面积污染。针对上述技术不足,设计一种将ZigBee与NB-IoT技术融合的新型白蚁侦测系统,该系统采用独创的白蚁侦测装置,能够高效准确地侦测蚁情;ZigBee-NB-IoT网络架构覆盖范围广且性价比高,实现信息的集中管理并能够有效稳定地将数据上传至云服务器;系统创新性地采用MSP430芯片作为侦测节点的"休眠保姆",实现全网同步休眠机制,最大程度上降低功耗,使系统能够长时间实时监测白蚁信息,工作人员可以通过终端设备查看侦测点的蚁情信息并进行精准灭杀,这样既提高了白蚁防治的效率又减小了对环境的污染。

Termite is one of the destructive pests in the world,which has a wide hazard range,including housing construction,transport facilities,river dikes,etc.These hazards are not easy to be perceived,but their consequences will be often serious as soon as they are found.The existing means of control over the termite are mainly achieved by large⁃scale spraying,which not only has low efficiency and high cost,but also causes large⁃area pollution to the environment.A new⁃type termite detection system integrated with ZigBee and NB⁃IoT technologies is designed for above technical deficiencies.In the system,a creative termite detection device is applied,which can detect termites′situation efficiently and accurately.The ZigBee⁃NB⁃IoT network architecture covers a wide range and has high cost performance,which can realize the centralized management of information and upload data to the cloud server effectively and stably.In the system,the MSP430 chip is innovatively used as the"sleeping babysitter"of the node detection to realize the synchronous sleep mechanism of the whole network,by which the power consumption can be reduced to the maximum extent,the system can monitor termite information in real time for a long time,and the staff can check the termite situation information at the detection station by means of the terminal equipment and perform the accurate killing.It not only improves the efficiency of termite control,but also reduces the environmental pollution.
