[attachment=54850]
Abstract
In this paper, we have developed the gateway for multi-information convergence system in ubiquitous sensor network. The gateway gathers the various sensor data from a road light device, and the data is transmitted into an energy management system. The sorts of data are the intensity of illumination, humidity and diagnostic results.
INTRODUCTION
In recent, a light source of road lamp equipment is replaced by LED type. In order to save the power consumption, the research of light source has progressed for various areas.
The growth of the digital technology and an internet made us to merge the LED, sensor and information technology. The advantage of LED can reduce the power consumption and an interface the LED with a sensor could have as well management as control of energy [1].
The convergence of such a LED and sensor based on an information technology provides more many opportunities to vendors and clients. The one is realized for home network or outdoor road light system [2].
The important study for this convergence system is an intelligent of the integrated devices. In order to implement the road lamp of LED type with sensor by network, we are interconnecting between lamp posts, which can integrate the platform of various LED device, sensor hardware specification and dimmer function [3].
In this paper, a sensor network for satisfying these have proposed the one of the node devices is the gateway. The gateway for the sensor network play role in gathering the data from around sensors and control a command. Then the gathered data is transmitted into an energy management system (EMS).
In this paper, we use the ad-hoc network technology to integrate the lamp posts. The gathered data by sensor networking is transmitted into EMS through the gateway. Also, we use wireless technology to transmit the gathered data among LED lamp posts. Finally, the data is transmitted into an EMS center, and then we use the CDMA technology. The EMS center can monitor variously the data obtained [4].
THE GATEWAY FOR LIGHT SENSOR
A sensor device has been used in road lamp system and the information of the sensors is transmitted into the control box through the gateway device. It controls the distributed box for control the lamp management system, reversely. Figure 2 shows the structure of sensor network for implementing the gateway [5].
The sorts of the sensors use CO2 sensor, intensity of illumination for measuring the light level and the humidity.
CONCLUSION
In this paper, we have developed the gateway that can interconnect between EMS center and the lamp post using the CDMA. The sensor node among road lamp posts can gather the various data like the intensity of illumination of LED, humidity and CO2. The one is transmitted into an EMS center through the gateway.
It is necessary for studying the chip to minimize the power and size of gateway. In the future, we must research for the data communication method of Ad-hoc network among the LED lamp posts in order to growth up the real time process and an efficiency of the network.
