<span>Local area network (LAN) as Bluetooth, WiFi and ZigBee are well established technology. The biggest problem with many LAN is the battery consumption and short ranges link budgets. LoRa is a new, private, unlicensed and spread spectrum modulation technique which allows sending low rates at extremely long ranges with minimal power consumption. More importantly, there is no access fee associated with this type of wireless technology. The main idea behind this work is to conduct performance and capability analysis of a currently available LoRa transceiver. We develop a location monitoring system using LoRa and global positioning system (GPS) module and we analyze the detectable range of its data, its battery consumption as well as received signal strength indicator (RSSI). Our deployment experiment demonstrates that the sy<span>stem is able to detect the transmitted data within 290 meters of distances. Using 6 volts of battery AA, the transmission of data still occurred after 24 hours</span>. <span>This project is emphasized a location monitoring system that provide low power usage</span> but long range.</span>

Electromechanical Equipment

The unattended electromechanical equipments are widely distributed in the harsh environment, which makes it difficult to construct the monitoring system. Therefore, this paper proposes a solution of the remote monitoring system based on Internet, which applies the VLAN (Virtual Local Area Network) technology in constructing the network. The network microprocessor STM32F107 is adopted to design a low-cost remote information terminal. The system software is designed based on B/S (Browser/Server) architecture by ASP (Active Server Page) technology, which implements SCADA (Supervisory Control and Data Acquisition) and pre-warning system for the unattended electromechanical equipments. The application shows that the system is stable, reliable and worth popularizing.

The Right

A network administrator has responsibility and important role in a computer network. Network security and its services depend on the treatment performed by the administrator. Network administrators who understand the workings of a computer network is needed to obtain the necessary computer networks. One of the obligations of the administrator is to monitor a network which can be done by using the system monitor. Monitoring system is a task to check the computer, operating system and services of computer network to keep the network always work in optimal conditions. In an effort to monitor the condition of the network, one of the technologies that can be used is the notification on twitter social media for providing information in real time to the administrator. Twitter is a social media that is very widely used, free, and secure. Moreover, the use of social media twitter experiencing rapid development. Therefore, the selection of twitter as a medium for the use of the notification is expected to be the right strategy. This system will be made by sending notification via twitter when a LAN network is disconnected or attacked by intruders.Results from the development of systems that have been made based on testing the functionality of the system shows all functions of the system has been running well. While usability testing calculation of the total score of the test system interface to get a score of 38.75 out of a maximum scale of 50. This score is in the range 34-42 value (Satisfied) which means that the respondents were satisfied with the system interface. Therefore, this interface is good to be implemented in the system.

Water sources in desert areas involved require manual on-site control, decentralized management, At the same time network interruption occurred occasionally. Based on this reason presents a LabVIEW-based network complementary monitoring system. This System achieves field device communication through the RS485 bus, using the Modbus protocol, then, realizes the communication between PLC, Power module Power module and the host PC through the serial port server by a wireless local area network or GPRS. The host computer develops monitoring interface through LabVIEW to achieve network complementary communication. Practice has proved that the system realizes simply, communicates reliably, and has a good expansibility, which has met the needs of remote monitoring of water sources and improved its management conditions.

The design of underwater monitoring system is an important component of fish domestication equipment for ocean ranching. In order to achieve the fish domestication effect so that to conduct feedback control of fish domestication device, this paper designs a wireless underwater camera monitoring system. The system includes local area network and GPRS network communication mode. The results of the underwater sealing experiment and the preliminary underwater camera test show the feasibility of the monitoring system. The effect monitored in Sparus macrocephalus domestication experiment in Xiangshan ocean area suggests that this camera system can not only meet the working requirements, but also be stable and reliable, which provides an effective means of monitoring for fish domestication on ocean ranching.
