IoT brings “voice” to machines, letting them talk to each other. Teldat’s customizable IoT solution exploits this dialogue with elevators to make maintenance operations easier.
The share of the urban population has significantly grown since the 1950’s at a quick pace: according to a United Nations’ studies in 2020 more than 80% in North and South America, and about 75% of inhabitants in Europe live in cities, with Asia and Africa averaging 50% and quickly increasing.
This trend is on the rise, fostered by the search of better job options, easier access to services, and a conscience to provide comfortable housing and cares to a growing elderly population.
As a result, elevators are a basic element any building must include and accordingly the installed base has grown together with the mentioned pattern of urban life.
An elevator is often a part of a building that doesn’t get too much attention until something goes wrong. And when a problem arises– like a malfunctioning door or a broken cable – it affects the normal operation of the building and its users (tenants or enterprises) and requires immediate action from the service technicians.
Together with the obvious safety considerations, regulation of this sector states that periodic maintenance by professional enterprises must be in place, and that scheduled inspections are mandatory – with hefty penalties if failing to pass these.
Regular predictive maintenance and elevator efficiency have a direct relationship—the better maintained a unit is, the more efficiently it will perform, thus reducing long-term costs. This translates into several key aspects.
With the growing number of elevators being fitted in all markets and a huge installed base, it’s becoming increasingly difficult for elevator manufacturers and maintenance companies to guarantee performance while maintaining a positive return on revenue.
For maintenance enterprises, the difficulties come from a shortage of technical expertise and the increasing costs of labor for elevator operations; whereas for elevator manufacturers, there is also the need to create a real-time stream of operational data for further product improvement.
Teldat’s solution transforms the current “fault-reactive” service practice, into a smart “fault-avoidance” practice, through advanced features such as state monitoring, remote management, data statistics, fault alarming, maintenance supervision, and more.
Our Predictive Maintenance for Elevators IoT solution is designed to gain actionable insights which help elevator maintenance enterprises reduce maintenance costs, minimize failure rates and thus provide a better service to end-customers - at a fraction of the cost of the current labor-intensive alternatives.
Our “Made in Germany” automated IoT solution can be fitted to older elevator models (retrofitting) in just minutes. In addition, a quick, true “plug&play“ installation process facilitates deployment and does not require costly training.
The state-of-the-art sensor is attached in seconds on the internal elevator’s door and communicates through BLE (Bluetooth Low Energy) to the IoT gateway. The robust IoT gateway is set up near the elevator hoistway to guarantee 4G/LTE connectivity to the mobile network through the embedded eSIM, and the system goes live in just minutes. Powering the IoT gateway is extremely simple through a 230VAC/5V DC transformer; the unit has a battery buffer to prevent power outage.
Thanks to the development of specific algorithms, data gathered by sensor vibrations are analyzed and processed in the sensor itself by means of edge-computing techniques.
These data accurately report door and hoistway situations in the different driving modes, elevator activity, door operation, maximum acceleration, door reversal counter speed and mileage & operating hours, among other relevant parameters. The system is capable to detect exactly the height position where vibrations were measured in combination with air flow sensor data. Therefore, technical service staff can easily see in which floor there might be a problem and proactively trigger the procedures to resolve the issue.
The cloud-based platform provides robust encryption (AES 256), data storage, data (de)compression and cloud computing, and delivers comprehensive dashboards suiting the customization and information needs of maintenance enterprises. Ubiquitous access to the information is granted through the web and a mobile app to maintenance staff and field technicians.
As a result, maintenance service is greatly improved, and cost savings are achieved:
