A Non-Intrusive Real-Time Current Data Acquisition System for Lift Monitoring
(REF: S-0117) |
| Matched I&T Wish |
|
| Trial Project |
|
| Solution Feature |
- Referring to I&T Wish (W-0158), firmware development includes current transformers to collect real-time current of Motor, Brake and Safety-link of the lift.
- The Microcontroller Unit (MCU) and software development to access the firmware in order to collect and process data.
- The development of the wireless (3G/4G) Data Transmission Module (DTM) to transfer the collected data from IoT terminal to upper host, store the data into files and display the data.
- Software and hardware system integration of the sensor module, MCU module and DTM module to store data.
- On-site installation & calibration so as to ensure the effectiveness of data collection for the Non-Intrusive Data Acquisition Lift Monitoring Prototype.
|
| Trial Application and Expected Outcome |
- Adoption of non-intrusive clamp type current sensors to guarantee the normal operation of the lift will not be affected.
- Using current sensors with high sampling frequency (latency >= 100ms) to make sure the data be collected in real-time.
- Adoption of 3G/4G wireless communication protocol so that the monitoring system can be installed under lift application scenarios, and easy to be widespread applied.
- Provide a foundation to support temporal data management and the further development of a large scale time series database.
