FieldServer as a distributed
sensing device consists of web-server, multi-sensors, web-camera,
wireless LAN module, high intensity LED lighting for environmental
measurement, plant/animal monitoring, farm observation at
fields or facilities in the long term. The functions of FieldServer
are following as:
As a sensing network node to transfer the wireless LAN signals and
monitor data and image such as pointing observation, safekeeping
monitoring, and disaster observation.
As a HotSpot in Internet to provide the wireless LAN
environments in the diameter of 100 m to several 100 m around
As a sensing system carrying out the sensors of temperature, humidity, and light
intensity as elementary configuration. Temperature and
humidity are measured in Assmann-style to avoid radiation
influence. As the options, following sensors can be selected.
There is a built-in a web-camera with resolution of 0.3 Megapixels. The web-camera can be changed to following:
with resolution of 3 Megapixel
・Camera with functions of
pan/tilt and zoom-in
・Microscope digital camera
As a pointing robot using servo to control the
power ON/OFF of the equipments in remote via network.
As an always online instrument to provide grid computing service
using field server engine and MetBroker.
As a all-in-one PC in outdoor performance to replace indoor
electronic instruments for creating platform. The field server
as a sensing network comprised of the devices is designed and
constructed in different shapes and functions based on the
application purpose and deployed place in order to create high
Robust and Parlous
The component devices of FieldServer as Web-Servers to operate
independently with the exception of sensors and lighting are
become to a robust system. The system can be performed via any
browser because of the web services in application layer and
wireless LAN and Ethernet interface of each devices in physical
layer. Therefore, the legacy problem of the USB-based or
RS-232-based devices caused from the update of the OS vision
will be solved in FieldServer successfully.
