Elevator IoT Monitoring System Application

1. Current Status Analysis

Few elevators are connected for networked monitoring; there are many elevator types with various status output interfaces, most of which are kept confidential and generally not open to the outside. As special products, elevators do not allow access by devices other than those from the manufacturer.

2. Operation Status Collection Content

3. Elevator status must be collected via non-intrusive access without any impact on elevator operation.

4. Operation, upward travel, leveling, downward travel, door open/close, occupied/vacant, current floor.

5. Detect 6 signals including upper limit forced deceleration, upper limit forced deceleration, brake, door lock circuit, lower door zone, and upper door zone, which can be combined to derive various statuses.

6. Infrared detection of whether there are people inside the elevator.

7. Operation Status Alarm Content

Overshoot to top, overshoot to bottom, prolonged door open, overload.

4. Status Reports and Submission

Fault count, fault category.

　 By installing various sensors, the elevator operation status is comprehensively monitored, mainly including: elevator running direction, elevator car door open/close status, elevator current floor, and elevator occupied/vacant status. Based on the content of the first phase, this elevator monitoring adds the following: elevator machine room temperature, elevator speed, water accumulation monitoring, and other information. Through these data, the current elevator status can be accurately known, providing reference information for handling personnel in case of emergencies.

　　Through sensors installed in the elevator machine room, elevator pit, and car top, common elevator fault alarms can be automatically analyzed and determined, including: non-leveling stop with/without people, elevator entrapment, prolonged elevator operation, elevator overspeed, elevator pit water accumulation, and machine room temperature. Alarms can be set as required.

　　Meanwhile, when elevator sensors detect an elevator fault, the system generates corresponding event information and sends it to the grid worker system, which handles subsequent work order dispatch and processing. At the same time, the elevator monitoring system retrieves real-time video footage inside the elevator, enabling elevator management personnel to immediately understand the internal situation of the elevator for convenient follow-up processing. After the event is resolved, video clips before and after the incident are retrieved and saved for future reference at any time.
