So now you're thinking about all the amazing ways that Freestyle IoT can work for you? Let's talk about how we can get you connected.
Let's organise a P2P chat about Freestyle IoT.
Rather go direct and talk to someone right now?
Chunghwa Telecom's gas clients needed to migrate their existing and diverse mechanical gas meter install-base to smart/intelligent meters. They wanted to create an online environment for consumers to view gas usage and billing information - in real-time.
They also needed a scalable and interoperable environment for:
|Meters:||Mechanical and smart meters from different vendors.|
|Gas Pipelines:||Utilising the same metering platform to control/monitor pipeline devices such as valve control, temperature, pressure, throughput and usage.|
|Sensors:||i.e. CO2, fire and smoke sensors from different vendors - both wired and wireless.|
|Advanced applications:||Standard gas application|
And finally, they wanted to create value for the gas companies and their customers.
Our partner in all of this is Chunghwa Telecom (CHT), Taiwan's leading telco. Chunghwa has, with the help of Freestyle, provided the Taiwan gas market with a cloud based management solution called CHTGMS. CHTGMS provides a dedicated Graphical User Interface (GUI) per gas company allowing for individual requirements to be catered to per gas company. CHT provides dedicated secure access to the CHTGMS and remote access to gas companies assets located anywhere in Taiwan.
CHT's gas solution allows gas company to easily connect different vendor devices (interoperability) to the CHTGMS. These devices include Taiwanese and Japanese smart gas meters; real time units (RTUs) used for pipeline management and numerous sensors both commercial and residential. As gas company requirements and functionality change over time, new devices are simply added to the CHTGMS or new functionality is downloaded to deployed FME enabled devices via our applications.
In addition gas companies have (and need) the ability to deploy advanced applications. These applications are simply deployed from CHTGMS and operate in real time without the need for back-end servers or human intervention. In the past, if an event was generated from a fire/smoke or CO2 sensor, the alarm would simply forward to a back-end server or an alarm panel.
CHT's Gas Safety application operates differently. For example, an advanced application is downloaded to a controlling gateway and when an alarm is generated by a fire, smoke or CO2 sensor, the application within the gateway:
It then sends an alarm to the CHTGMS, which then:
CHTGMS provides gas usage and billing information either via each gas company GUI or via the internet and can be displayed on any number of media devices such as smart phones and tablets.
Chunghwa Telecom (CHT's) end-to-end solution is entirely supplied by Freestyle.
IoT our way means a win-win scenario for utility companies and their customers.
