Power monitoring data detected by wireless sensor nodes was analyzed in individual stores. The result obtained in one store was summarized in Fig. 5, showing the result of power profiling of CVS. Horizontal axis presents day’s average temperature in Tachikawa area (in the center in terms of north and south and a little west of Tokyo Metropolitan area). Power consumption of display cooler and freezers and air-conditioning changed largely with temperature. More detail, power consumption of display cooler increases in a parabolas fashion with increasing temperature. That of air-conditioning shows minimum around 15 degree in spring and autumn season. These changes cause this trend of total power consumption of CVS against average temperature. On the contrary, power consumption of equipment worked by “single-phase AC” and some equipment worked by “three-phase AC” kept almost constant with temperature changes. There is a lot of equipment worked by single-phase AC. As shown in Fig.6, the equipment used on shop counter, such as heating food and coffee machine, and lighting shows large contribution to total power consumption. It can be assumed that power consumption of single-phase AC shows similar values due to day’s temperature. Single-phase AC (200V) Wireless Sensor Nodes Three-phase AC (200V) 11-13 May 2011, Aix-en-Provence, France Power Consumption kWh/day Though the equipment of store H is older than that of store J, power consumption of store H shows similar changes with the store J. This is because store H has good installation environment of outdoor-unit. On the contrary, the oldest equipment of store F shows different changes with other stores. This may be caused by degradation of equipment and characteristic with non-invertor.

Schematic power consumption in CVS. Three-phase AC (200V) Fig. 7 shows both fitted curve of individual stores and features of equipment which are installation date and performance. The latest equipment in store J shows low power consumption. As the equipment gets older in store D, F & G, curves shift direction to larger values without store H. IV. SUMMARY We have applied prototypes of wireless sensor nodes and network system to monitoring the power consumption of equipment in convenience stores as one of the important applications for commercial power monitoring. The prototype of sensor node is a wireless current clamp-on type probes integrated with a thermometer and the system enables simultaneous monitoring of 50 power lines. Using the sensor nodes and system, power consumption monitoring of 10 convenience stores has been successfully demonstrated. It has been found that for this application, besides the low cost of sensor systems, ease of installation and undisturbed environment in setting monitoring system were strongly required. For achieving these properties and the low cost of sensor systems, it would be necessary to have wireless and non-battery system, small size sensor nodes. ACKNOWLEDGMENT The authors thank Seven-Eleven Japan Co., Ltd. for the assistance of the power monitoring experiment in the stores. 229
