For the sake of overcoming the shortcoming of some equipment such as complex wiring and much measurement parameter, a wireless state monitoring system is developed based on Zigbee, which was composed of upper monitor control PC, wireless gateway CC2530, sensor node CC2530 and sensor module. By studying the characteristic of the equipment, wireless sensor network of a center controller and six wireless sensor node was made up. Then the nod hardware circuit were designed, the wireless module software was programmed by C language, and furthermore, the user interface software was developed based on LabVIEW. The test is done to show that the system can meet state monitoring requirements for some equipment.

Wired electric equipment overheating monitoring system has some limitations in electric propulsion ships. This paper designs an electrical equipment overheat monitoring system based on Wireless Sensor Network (WSN) to monitor the overheat of electrical equipment. To verify the performance of the whole system, we design the hardware and the software of sensor nodes and coordinators. In order to extend the lifetime of sensor node effectively, the system adopts the dynamic sleep and controllable transmit power method. The results show that this system achieves the accurate measurement of electrical equipment temperature. At the same time, laboratory data tests shown that it can achieve the same accuracy as wired measurements. This paper provides a new solution for overheating monitoring of marine electrical equipment.

Usage Data

<p>The fourth Industrial Revolution has led to tremendous change in industrial automation. Measurement system can be seen as an important tool implemented in various fields because it enables us to access essential data from the environment or desired location. One of the essential measurement systems in industry, company or home is water usage monitoring. Water usage monitoring is the regular collection of information on the total amount of water drawn from sources during a given period. It enables a company or industry to understand water usage patterns and identify potential inefficiencies. For instance, a hotel premise who wants to monitor its water usage per room basis. Monitoring is also essential to set reduction targets of water used. The paper presents the development of wireless water usage monitoring system. This system consists of two nodes which are sensor node and sink node. The sensor node collects the water usage data and send them to the sink node. An ultrasonic sensor, Light-Emitting Diode (LED) and buzzer are attached to the sensor node as alert system for the user in case of water wastage occurrence. The sink node receives data from the sensor node wirelessly and mark this data time stamp by referring to a Real Time Clock (RTC) and store it in the database. The database is attached to sink node with Secure Digital (SD) card module. Furthermore, a Graphical User Interface (GUI) is used to display the water usage data in graphical form for easier user interpretation. The proposed wireless water usage monitoring system is suitable for home and small premises usage.</p>
