IDM Smart Elevator Management System Solution
1.1 Elevator Safety
In recent years, with the rapid development of urbanization, the installation of elevators in old residential communities and the increase in high-rise residential buildings and office buildings have led to a rapid growth in the number of elevators as a means of public transportation. However, problems such as elevator malfunctions, unreachable emergency calls, no mobile phone signal, trapped passengers unable to call for help from outside, and elevator maintenance have also become increasingly prominent. Elevator safety has become a new hidden danger to urban public safety.
Our IDM Smart Elevator Management System conducts scientific information-based management of elevator data, enabling dynamic management, aggregated analysis, and timely early warning of potential accident hazards, ensuring the personal safety of users.
1.2 Elevator Safety Hazard Factors
What are people most afraid of when taking an elevator?
Elevator malfunctions, power outages, rapid descent in a dark box, over-travel to the top, emergency communication buttons that are non-functional, no one answering, or no signal at all, no mobile phone signal...
Inadequate safety supervision, substandard equipment maintenance in many residential communities, and various hidden hazards of varying degrees.
Untimely fault alarms and safety rescue. When an elevator malfunctions, rescue calls go unanswered, and rescue personnel cannot arrive at the scene in time.
Trapped passengers unable to contact the outside world in a timely manner, lacking personnel reassurance and proper response measures, which can easily lead to blind self-rescue attempts and secondary injuries.
1.3 Current Status of the Elevator Industry
1. Imperfect maintenance management, failing to push regular maintenance records to the person in charge of the unit.
2. The real-time operating status of elevators cannot be transmitted to property management companies and maintenance companies in a timely manner, making on-demand maintenance impossible.
3. Maintenance personnel work off-site, and the on-site conditions cannot be promptly understood by maintenance supervisors and property management companies. Elevator maintenance items are few, and due to insufficiently refined property management methods, there are many discrepancies in maintenance items, leading to frequent malfunctions, trapped passengers, and greater safety hazards.
4. The connectivity rate of the five-party intercom system is low, and calls cannot be made in emergency situations.
5. Insufficient maintenance funds. It is often difficult to collect adequate maintenance fees. Elevator operation and maintenance fees are generally collected together with community property fees, and some individual residents do not pay property fees. The fees paid by property management to maintenance companies are low.
6. The level of elevator informatization, especially intelligence, is not high.

3.1 Elevator IoT Monitoring System
Comprehensive monitoring of elevator operational status is achieved by installing various sensors, primarily covering: elevator running direction, elevator car door open/close status, current floor of the elevator, and elevator occupancy. Based on the content of the first phase construction, this elevator monitoring phase adds the following: elevator machine room temperature, elevator speed, and water accumulation monitoring. This data accurately reflects the elevator's current status, providing reference information for handling personnel in case of emergencies.
Sensors installed in the elevator machine room, elevator pit, and on top of the car enable automatic analysis to determine common elevator fault alarms, including: non-leveling stops with/without passengers, elevator entrapment, prolonged elevator operation, elevator overspeed, water accumulation in the elevator pit, and machine room temperature. Alarms can be configured as needed.
Furthermore, when elevator sensors detect a fault, the system generates corresponding event information and transmits it to the grid member system. The grid member system handles subsequent work order dispatch and processing. Simultaneously, the elevator monitoring system retrieves real-time video footage from within the elevator car, allowing elevator management personnel to immediately understand the internal situation for convenient follow-up processing. After the event is resolved, video segments from before and after the incident are retrieved and saved for future reference.

5.2 Elevator Operation and Maintenance Work Order Management
1. Maintenance Work Order Management
The system automatically tracks time based on the most recent maintenance date for each elevator. A yellow warning is pushed daily to the relevant maintenance company personnel starting 3 days before the maintenance countdown expires. A red alarm is pushed upon expiration. Once a red alarm is generated, the information is pushed to the Market Supervision Administration (MSA) users.
The MSA selects and confirms key items within the elevator maintenance checklist. The system processes these key items with photo + watermark capture. The system records the maintenance start time, end time, and completion time for each item.
Simultaneously, by comparing time data (start time, end time) with maintenance records from the provincial platform (currently updated daily by the provincial platform), the confirmed deviation tolerance is currently 15 minutes (adjustable via system configuration). If the deviation exceeds this range, the system automatically determines it as abnormal maintenance. MSA users can view the system's statistical results of comparison anomalies at any time.
2. Work Order Recording and Printing
The system records the maintenance process. Electronic signatures are performed upon work completion and are only reflected in the electronic work order. The printing process allows the option to include or exclude the electronic signature. The signature section on the printed paper work order is filled in by relevant personnel and submitted to the MSA, where the paper work order can be archived.
3. Maintenance Task Management
For the maintenance work orders from the first phase construction, targeted photo requirements are added to relevant maintenance items within the work orders, implementing a photo-only method to prevent fraudulent practices.
To further enhance the authenticity of maintenance, images for each item requiring a photo are processed by adding a time watermark directly to the generated image, ensuring the authenticity and validity of the photos.
4. Maintenance Supervision Work Order
The maintenance supervision work order function primarily adds a supervision feature to the system maintenance work orders, further enhancing maintenance authenticity through supervision.

8.3 IDM Smart Elevator IoT Sensors, etc.
1. Car camera, DVR
Storage DVR with local video storage for one month. In the event of an elevator accident, local video review is available, while also serving as a forwarding device for elevator video stream signals.
Through the MQTT protocol, data from a large number of industrial devices across different areas on site can be connected to the IoT platform via the Internet, enabling monitoring, equipment diagnosis, program maintenance, and fault alarm functions. This provides users with a simple and reliable industrial Internet data remote transmission solution for industrial mutual control, equipment diagnosis, program maintenance, and fault alarms.
2. Pit water accumulation
For pit water accumulation, we can add water accumulation detection in the pit according to the elevator maintenance company's requirements, with specific standards determined by the maintenance company. When the system detects water accumulation, the platform issues an alarm work order to the designated personnel's APP. Upon receiving the work order, the personnel confirms receipt of the alarm, arrives on site to begin handling, and records on-site photos and the handling process in the work order.
3. Machine room ambient temperature sensor
In response to the requirements proposed by the market supervision bureau, we have replaced the original traction machine temperature sensor with a temperature sensor to continuously monitor the elevator machine room temperature. When the machine room temperature is too high, the system sends alarm information to the staff APP in the form of a work order through the platform, notifying maintenance personnel to inspect and handle the issue in the machine room.
8.4 IDM Elevator Access Control Terminal
Face Recognition Voice Recognition Mobile App
8.5 IDM Elevator Status Acquisition Terminal
Smart elevator floor selection can be achieved through facial recognition, voice-controlled floor selection, and mobile APP elevator reservation. Surveillance cameras inside the elevator can detect prohibited items such as electric bicycles. When a prohibited item is detected, passengers are immediately warned. If a passenger insists on riding the elevator, the system will immediately notify backend management personnel, who will handle the situation through the intercom system.
