summary

A module that plugs into a power outlet enables identification of power devices that serve as loads from their power consumption waveforms without IoT, and provides low-cost device identification for the entire power grid. By setting the load to be prioritized when emergency power sources are connected, power can be used safely up to the maximum load without causing a crackout even with limited power generation. For use during normal times, power equipment can be turned off remotely while identifying the type and usage status of power equipment that is idle.

Technical Strengths

This technology enables control of many non-IoT power devices, and its PLC (Power Line Internet) communication function eliminates the need to install a dedicated information network, and an Internet communication network between the modules can be configured without wiring work, contributing to rapid shelter setup. The remote ON/OFF function combined with device identification can greatly reduce labor for power-saving activities in a large facility, and the control module can also realize timer operation and other efficiency improvements, resulting in significant management labor savings.

Case Studies (Including Demonstration Results)

Municipalities served

Demonstration module has already been manufactured and successfully tested in Gunma University Hospital.

Case Studies

Multiple equipment identification (soldering irons, laser printers, ultrasound equipment, PCs, etc.) could be performed between different power system floors across the distribution board. Also, equipment could be turned on and off remotely.

scale of implementation

The equipment is compact and requires no installation work, so it can be installed by a single person. Three units were used in the demonstration. The device identification information is transmitted in packets of Fourier-transformed and frequency-analyzed data, rather than in the form of time-varying power waveforms themselves, to ensure reliable communication even when power line communication quality is poor.

Time to delivery

Currently in the R&D phase for product miniaturization and weather resistance

Price (if paid)

The target is to sell the product at 20,000-30,000 yen per unit (per outlet).

Other Case Studies

Since the system is in the demonstration stage, we would like to actively test its operation if there is an environment in which we can test the system in the future.

How to use in peacetime

Power-saving activities often involve patrolling, visual inspection, and manual operation, which places a heavy physical burden on workers in medical institutions, high-rise buildings, evacuation centers, and other buildings with large floor areas and large distances to travel. This technology allows remote ON/OFF of power devices while identifying them, and automatic ON/OFF by timer, which leads to more frequent and reliable power-saving activities and reduces the workload of workers while increasing the effectiveness of activities to reduce soaring electricity bills.
