Service introduction

World Best Quality, Global Partner EL Tech Co., Ltd.

Preliminary identification of structural hazards

• Damage to adjacent buildings due

to constructions

• Notification of evacuation from

dangerous situations

Damage to adjacent buildings due to

constructions

IoT Sensor based structural health monitoring system is

required.

NECESSITY OF THE SYSTEM


Data accumulation for structure health

• Long-term health tracking

• Prevention of major accidents

Securing the soundness of infrastructure Damage caused by insufficient safety

diagnosis system

IoT sensor based automatic safety diagnosis required

• Preventing the damage due to

insufficient safety diagnosis

• Recognizing the inaccurate case

due to visual inspection

Risk situation Sensor data displayMessagenotification

SERVICE OVERVIEW

� Real time notification and data checking through mobile app.


Using clockwise data

- Judgement of long term displacement of structure

- Determination of maintenance schedule and direction

- Determination of displacement according to temperature, humidity, etc

- Determination of safety threshold

Utilization of accumulated data in emergency

- Judgement when the first structural error occurred

- Minimization of casualty through fast warning

- Comprehensive judgements by combining many types of sensors such as vibration, crack, humidity and etc

SERVICE OVERVIEW

� Securing safety prediction through big data


Proven system with rich application examples

Reduction of cost by operating own network

Minimization of damage to the structure to be attached

Real time unmanned measurements reduce maintenance cost

Efficient automation of structural health management

Data collection linked with various sensortypes

Provide additional services through big data techniques
