In order to solve the shortcomings of the landslide monitoring technology method, a set of landslides monitoring and early warning system is designed. It can achieve real-time sensor data acquisition, remote transmission and query display. In addition, aiming at the harsh environment of landslide monitoring and the performance requirements of the monitoring system, an improved minimum hop routing protocol is proposed. It can reduce network energy consumption, enhance network robustness, and improve node layout and networking flexibility. In order to realize the remote transmission of data, GPRS wireless communication is used to transmit monitoring data. Combined with remote monitoring center, real-time data display, query, preservation and landslide warning and prediction are realized. The results show that the sensor data acquisition system is accurate, the system is stable, and the node network is flexible. Therefore, the monitoring system has a good use value.

Monitoring And Early Warning

In order to solve problems of the absence of security protection and the lack of early warning mechanism in the current elevator operation process, elevator safety monitoring and early warning system based on directional antenna transmission technology was proposed. The system includes sensor module circuit, microcontroller module circuit, display module, directional antenna transmission module, remote server and data monitoring system. Design ideas of hardware development, remote server and data monitoring system are introduced. Two version monitoring software are written, one for PC monitor, the other one for mobile phone monitoring. In order to improve data transmission distance, transmission rate and transmission quality, automatic antenna alignment system is designed, which combines the advantages of directional antennas and omnidirectional antennas transmission technique. To overcome problems such as instability of the alignment process, delay and other factors, DMC（ Dynamic Matrix Control ） algorithm should be used in the system and optimal control of the antenna angular alignment will be achieved. The system can continuously transmit real-time elevator’s working status information and environmental information, and it also send commands to notify elevator company managers once an abnormal conditions occur in the elevator, so that people can take urgent measures and maintenance measures. This system can be applied to real-time warning of all-types elevators.

Smart village merupakan sebuah ekosistem yang melibatkan pemerintahan, industri, akademisi ataupun masyarakat untuk mejadikan desa lebih baik. Konsep smart village diharapkan mampu membuat masyarakat desa dapat mengetahui permasalahan disekitar daerahnya. Dalam 10 tahun terakhir ini permasalahan yang timbul dan mengalami peningkatan yaitu pada sektor bencana, selain itu permasalahan yang timbul adalah kriminalitas, bahwa pada tahun 2018 indexs kejahatan diindonesia mencapai peringkat 68 dari 147 negara. Dalam hal ini Indonesia khususnya didaerah pedesaan perlu adanya sebuah sistem yang dapat memberitahukan peringatan dini bencana dan kriminalitas dengan real time berbasis Internet of Things, dimana sistem ini akan saling terhubung antara website pemerintah desa dengan warga. Early warning system ini dibangun menggunakan metode prototyping, dimana metode ini dimulai dengan mengidentifikasi masalah yang terjadi dilapangan, lalu desain sistem, pengujian dan implementasi. Early warning System ini pula dibangun dengan sebuah tiang yang dilengkapi dengan sensor kebakaran, gempa, kualitas udara, panic button, lampu otomatis dan kamera monitoring system untuk memonitor keadaan sekitar layaknya CCTV. Hasil dari input-an pada sensor akan diproses oleh mikrokontroller dan dikirim pada webservice untuk diteruskan pada smartphone.

The rational database including the distribution, changes and testing facilities status of temperature & humidity in tea garden is created using the MapInfo 9.5. A set of the tea garden wireless utilities is established using the ZigBee module. The temperature & humidity real-time monitoring system and early warning system for Frost Prevention is established using Mapbasic. This system can get real-time information of temperature & humidity of nodes in different locations and give frost warning early. The frost prevention fans can be timely started, once temperature inversion happens. At the same time, the manager of tea garden can realize real-time monitor of the work status and quick location of facilities with the help of GPS.
