A remote fish finder system for effective set-net fishery, which enable to visualize as well as recognize catch amount and the fish kind, is proposed in this paper. In order to improve fishing efficiency and obtain the highest possible profit of set-net fishery, set-net monitoring is needed by coastal fishermen. Set-net monitoring can be used to estimate fish catch amount within the set-net, fish...
Recently, attentions are focused more on bus interior network application and the wireless bus-carry data transmission technology. For developing a remote monitoring system, three aspects of the system are discussed: the vehicle interior network configuration, the CAN/GPRS gateway realization and the remote monitoring server design. Described in the paper are the hardware and software design of the...
This paper presents the design and development of an online monitoring system that collects data over time or distance with a built-in instrument or sensors. Currently, an online data collection system (Vehicle Data logger) from general vehicle is not available in the market. Only the vehicles' manufacturers have the tool to access the engine ECU to monitor the vehicle's data. Current available automotives...

It is effective to observe a person's state while protecting individual's information. FG Vision Sensor is able to acquire three-dimensional information and it can thus offer confidentiality. It is appropriate because the processing speed, when used in a monitoring system, is fast. In this research, we propose to recognize a person's state by using FG vision sensor.
This paper introduces a radioactive source tracer anti-theft system, which mainly consists of three parts-Detection probe, Tracker and PC. It is based on RFID, GSM and GPS. The system can realize non-contact information acquisition processing for the stolen radioactive source. If there is unauthorized or illegal movement of radioactive sources, GPS/GSM system which is installed in the radioactive...
As we known, to evaluate and diagnosis the insulation faults of large-size power transformers, partial discharges (PDs) can be detected via ultra high frequency (UHF) technique. In this paper, an UHF PD online monitoring system was developed for large-size step-up transformers. The principle of UHF PD monitoring method was introduced., and the hardware structure and software key techniques in the...
In the last years, the presence of WSN (Wireless Sensor Network) is spreading worldwide. The reason for this success is that they facilitate the creation of data acquisition networks minimizing the necessary wire infrastructure. However, the WSN distributed modules typically have high dependencies on their batteries consumption. In the other hand, event-based systems are spreading fastly day by day...
To access the batteries information in the process of charge and discharge in time, the article designed a monitoring system for the condition of storage batteries based on ZigBee. This approach used the chip of CC2430, which was integrated of AD converter, 8-bit strengthened MCU and wireless RF unit. The chip of CC2430 and the external circuits were made up the node of the star network. The temperature,...
The paper introduced the structure of power monitor system, and discussed the realization of communication between monitor center and monitoring data acquisition device and designed the interface and database of monitor center.
In the natural sciences, research often relies on extensive manual investigation. Such methods can be error-prone and obviously don't scale well. The development of autonomous data acquisition systems such as Wireless Sensor Networks (WSN) has provided a method to significantly reduce manual work and, as such, has the potential to enable researchers to address previously infeasible scientific questions...
Wireless sensor networks have to be very flexible and self-configuring, providing an easy way to be deployed. This is a feature that is required due to a wide spectrum of possible applications and deployment scenarios in which they can be used. They can support different kinds of tools and applications in distinct areas, such as agriculture, military, health care, home or industry automation and others...
The use of a social network for monitoring a geographic area introduces the possibility of realizing new applications. Monitoring wide areas with video-surveillance and remote sensing techniques is extremely expensive in relation to the spatial and temporal resolution. This means involving inhabitants, workers and visitors of parks, urban and heritage wide areas in environmental monitoring process...
