The Era of the Internet of Things has seen a proliferation of
inexpensive cheaper sensors, transducers, and data transmission
vehicles.This, accompanied with enhanced security technologies, has made
customers in various vertical markets more willing to allow their data
to stream over the network for IoT applications. Equipment
manufacturers, faced with such market trends, are considering how to
leverage new technologies to seize the newly burgeoning business
opportunities.
Our customer in this case is one of Asia’s most
active elevator/escalator suppliers, who has installed over 3,500
elevators/escalators in Taiwan alone, not to mention their growing
business base in mainland China and other Asian countries. Imagine the
complicated management and huge resources involved in their repair and
maintenance works.
With new technologies available, they were
seeking a new management system that could help remotely monitor and
control their installed elevators/escalators, and therefore develop a
more proactive and intelligent maintenance model that streamlined their
workflow with improved efficiency and economy. They wanted to replace
their traditional, regular itinerary of on-site inspections and
failure-reactive model.
Leveraging the solution provided by
Advantech, our customer successfully developed a proactive
elevator/escalator maintenance system that collects real time operation
data from the elevators/escalators, automatically halting the operation
of elevators orescalators where monitored parameters reach dangerous
thresholds, and alerting the company for needed repairs or
componentrenewals. After a 4 to 5 month development period, the system
is ready for rolling out, about one and a half years earlier than if
they had done it on their own without the help of the Advantech
solution.
Application Requirements
After deploying
sensors including motor temperature and vibration on each
elevator/escalator, the customer needed to install an IoT gateway near
the elevator/escalator control system to collect data from sensors via
wireless or wired transmission and convert the data (either digital or
analog with different formats) into a unified IoT protocol data format
and upload the data over the Internet to the remote backend server at
the elevator company. If the gateway were provided with sufficient
computing power and intelligent capabilities, it would be able to
preprocess data, implementing certain monitoring control tasks and
uploading only significant data to the backend server. This would help
reduce server loading and save tremendously on communication expenses.
An intelligentserver with adequate computing power was recommended for
this gateway deployed at the edge of the network.
System Solution
For this application, Advantech provided
EIS-D150 for device monitoring and data manageability, which is equipped
with the Intel®Core™ i5 processing power needed to support large-volume
I/O applications. The Advantech EIS
series comprises solution-ready platforms preconfigured with the
software resources needed for IoT connectivity, data manageability, and
cloud services. The EIS
solution includes many of Advantech’s powerful software tools,
including WISE-PaaS/RMM, an open-standard IoT device remote monitoring
and management platform. The WISE-PaaS/RMM can be interlinked
withAdvantech’s SCADA software, WebAccess/SCADA, which provides high
volume I/O support for large-scale sensor data collection andI/O
controls, as well as intuitive graphical user interfaces for supervisory
management.
The WebAccess/SCADA is a powerful platform for easy
data acquisition and integration, providing over 200 drivers for
connecting with sensors and equipment using different industrial
communication protocols. For example, the customer in this case uses
OPCUA industrial standard for its injection devices; with
WebAccess/SCADA, the user can connect the injection devices to the
monitoring control system without needing to do protocol conversion.
With WebAccess/SCADA, a single EIS-D150 is able to connect with and
control over 5,000 I/O points, delivering great systemextendibility and
compatibility for system expansion in the future. WebAccess/HMI software
can be used to visualize data and flow.
The hot runner monitoring
system continuously checks whether all tasks are being completed to
spec as required, and if not, it makesautomatic adjustments according to
environmental and operational parameters. This requires edge
intelligence computing andlogic flow control. Also contained in the
Advantech solution package is Node-RED, a powerful logic-flow editing
tool with an intuitivegraphical interface, which helps greatly to
visualize the process.
Meanwhile, the Advantech EIS solution
also has WISE-Agent built-in. WISE-Agent contains a conversion tool for
transforming data into MQTT, IoT-standard language, for upload to a
backend server or to the cloud. A Microsoft Azure package is also
pre-configured hereto provide optional access to big data analysis or
other cloud services.
