Theme



II. Background



V. Conclusions


Current status and issues of bridge management in Japan

Increased obsolete

social infrastructure

will increase the cost

of maintenance and

renewal


MIC’s Project

“Establishment of an ICT platform for smart infrastructure maintenance”

MIC has conducted R&D into communication technologies for highly

reliable and ultra-low power consuming, gathering and transmitting

data on distortion and vibrations, etc. from sensors to achieve ICT-

based effective and efficient maintenance of social infrastructure.

We conducted this part of the project

and developed an ultra low power

wireless communication technology

Short Range Wireless Communication

Long Range Wireless Communication


Achievement Goals of the Project

Power consumption :

less than 1/1000 of the conventional technology.

( eg. BLE, IEEE 802.15.4, EnOcean, etc. )

Communication range:

up to 5-10m near steel or concrete infrastructure

Data collecting speed from 30 sensors:

less than 1/10 of the conventional technology.

Consider Information security:

Authentication and encryption necessary

The project is not scientific research, but practical technology

development and has concrete goals.

It is challenging to achieve all goals at the same time.

We can assign time slot to each tag in advance

and collect data sequentially in one round-trip

Feature #3 : Secure Communication

To achieve this objective, we adopted lightweight cipher technology.


Consider Information security: Authentication and encryption necessary

Sorry, details are secret!


Secure communication consumes a lot of power.

If you don’t

mind security,

harvester

works well.

If you care

about security,

you need

powerline.

Our secure wireless technology consumes only few μJ per communication!!

(EnOcean’s non-secure wireless technology consumes ～150μJ per communication)
