Monitor performance and optimize maintenance with the lift monitoring system by Bosch.IO and TÜV SÜD
Lifts are a critical part of a multistory building’s infrastructure. In seeking to ensure their safe and reliable functioning, building owners and maintenance service providers face many challenges, ranging from the lack of operational transparency to the shortage of skilled technicians.
To address these challenges, Bosch.IO in collaboration with lift domain expert TÜV SÜD developed the Lift Manager – an end-to-end IoT solution for centralized remote monitoring and predictive maintenance of lifts. It can pull data from any lifts – regardless of brand or location – onto a single dashboard that tracks physical condition, utilization, and ride comfort and sends alerts if anomalies are detected. Noninvasive installation of sensors on top of the lift cabin provides an easy way to retrofit the installed base. Predictive analytics enables the system to forecast the remaining time to downtime and recommend a specific maintenance activity to prevent a breakdown.
The Lift Manager is part of the Connected Building Services, which is built on top of the Bosch IoT Suite. This set of solutions delivers comprehensive information on how building infrastructure is performing straight into the hands of building owners and facility managers.
Lift Manager features
A unified dashboard for all the lifts in the building or across multiple properties enables central tracking of anomalies, lifts condition, and maintenance. This improves operational transparency and efficiency and saves time of lift operators by eliminating the need for physical checks and extensive paperwork. Instead, all necessary data is immediately accessible. Additionally, this also helps maintain compliance and easily provide proof of safe operation with detailed reports on service history.
Read this story to learn how a business park in Singapore saves up to 14,000 man-hours a year after the digitalization of their lift management process, reducing the pressure on facility managers and allowing them to redirect their efforts to other tasks.
The system tracks each lift’s status round-the-clock and monitors key lift parameters such as physical condition, utilization, and ride comfort. Operators can see real-time data and historical trends.
Notifications and escalations
The Lift Manager promptly detects lift parameters that fall outside the predefined range for normal lift operations. The system notifies support staff of critical events and, if necessary, escalates an issue to maintenance staff. Thus, a response time to major problems such as mantrap, incorrect leveling of the cabin floor, and door opening/closing issues can be significantly improved.
Upon evaluating the data collected from lift operations, predictive analytics is applied to forecast faults. Moreover, the Lift Manager identifies a root cause of a detected anomaly and provides clear guidance on what components need to be fixed. Recommended maintenance actions are prioritized according to the estimated time left until a faulty part is expected to fail. This enables better targeted maintenance planning, saving costs on building operations and minimizing lift downtime. Take a look at our white paper “Algorithm-based data analytics for lifts” to learn how it works.
The system monitors the duration and frequency of maintenance checks, tracks their lapses, and compares lift performance before and after maintenance. You can get a full report on repair history of any lift with just a few clicks without having to dive into multiple documents.
Lift Manager solution components
For the Lift Manager, we use a compact and robust Bosch integrated sensor device customized specifically for harsh industrial environments. This device contains various sensors – environmental, light, and acoustic sensors; magnetometer, accelerometer, and gyroscope – and can track a multitude of lift parameters. To monitor lift car leveling, a laser range finder is used. A gateway device serves as a bridge to connect sensors with the cloud; it also enables edge computing capabilities.
Sensors and gateways can be easily and quickly installed on the lift car top. This noninvasive installation is straightforward, fuss-free, and enables a retrofit of any lift, regardless of brand.
The Lift Manager is provided as a cloud-based SaaS (Solution as a Service). Its intelligent software collects readings from sensors installed on the lift car and structures and analyzes the data. These results are then visualized and presented in graphical form.
The graphical dashboard provides a full overview of lift performance and maintenance activities. It delivers event notifications and alerts operators to incidents such as abnormal vibrations, stuck doors, or a lift car leveling outside of the accepted range. It also provides valuable insights, displaying utilization, maintenance, and other trends. An elaborate predictive analytics methodology is used to identify the remaining time to downtime and give recommendations as to which specific maintenance activity should be carried out to prevent a breakdown.
Importantly, the system provides open APIs to allow integration with third-party solutions. This ensures easy linking to existing BMS systems and supports future scalability of the solution.
The dashboard is available through a web browser, which means that facility managers and lift maintenance staff can access it on their laptops or tablets anywhere, anytime.
At the heart of the solution is the Bosch IoT Suite. This provides unified access in order to connect gateways and sensors, and enables their remote configuration and monitoring as well as firmware/software updates over the air. As a result, it takes minimal effort to run the Lift Manager.
Our solution comes with a comprehensive set of services:
- Installation of sensors
- Onboarding of the lifts to the Connected Building system
- System customization and integration with the existing Building Management System (BMS)*
- Training of system operators*
- Replacement of sensors when necessary
*Optional, not part of the standard package.
