1. Scene background 
Previously, elevator problems relied on two methods: either passengers were trapped and pressed for emergency calls, or the property management manually climbed the stairs for weekly inspections. For example, when the elevator suddenly shook, it was discovered during inspection that the operating sensor was loose, almost posing a safety hazard.

2. Product selection 
Inhand IR302 Industrial Router (capable of withstanding the vibration/electromagnetic interference of elevator operation, supporting 4G network of operators, and can also connect multiple elevator devices simultaneously)

3. Core issues 
The operation status of the elevator (such as whether the door is closed properly or whether it runs steadily) cannot be monitored in real time, and faults will only be known when there is an accident; 
The operation sensors and emergency call data in the elevator are separated, making it impossible to transmit information uniformly; 
The office building has high floors and thick walls, and ordinary routers have no signal in elevators, so data cannot be transmitted.

4. Solution 
Use IR302 to connect the elevator's operation sensors (measuring floor and speed) and door switch detectors, and IR302 will transmit these status data in real time to the property's cloud management platform; 
Unified transmission of "safety signal": The emergency call device of the elevator is also connected to IR302. When passengers press the call button, the signal will be directly popped up to the property's computer and mobile phone through the router, and the current floor of the elevator will be attached; 
Stable connection signal without "chain drop": The signal penetration of IR302 is strong, and data transmission will not be interrupted.

5. Implementation effect 
Fault response is 80% faster: issues such as elevator doors not closing properly or sensor abnormalities will be automatically alerted by the platform, and the property management can send someone to handle them within 5 minutes (previously it took 20 minutes); 
No need for "climbing inspections" anymore: the number of manual inspections has been reduced from twice a week to once a month, saving the workload of two inspectors for the property management;
