This solution is a set of communication solutions customized for elevator Internet of things industry. Through the real-time transmission of elevator monitoring data, realize uninterrupted and real-time monitoring and remote management of the running elevator, ensure the safe and reliable transmission of elevator data, and ensure the stability and uninterrupted operation of the elevator material-to-thing network. The scheme also provides value-added services such as elevator remote audio and video services, which are comprehensive, low cost, easy to manage and low operation and maintenance costs.

Features:

1, the WEB directly display elevator location, support automatic positioning and manual modification (drag the mouse directly)

2. Elevator alarm information is pushed directly to the WEB, and mobile phone push and reply is supported

3, VOIP call, WEB click to call directly to the elevator car, remote contact with the five party communication system

4, remote video monitoring, WEB click directly for elevator cage remote video monitoring

5. Video superposition (such as: display floor, upstream and downstream, elevator name, location, time, etc.), and remote real-time view of cage video, video local storage (DTU built-in mobile hard disk or U disk)

6. Support cage advertisement playing, audio and video advertisement local storage and remote distribution

The phone APP

The server will push the elevator fault alarm directly to the mobile phone of the maintenance personnel. The maintenance personnel can check the location of the elevator through the map, click the alarm information to view the content, and then carry out the operation of receiving orders, arriving at the site, and completing the maintenance. The operation above the mobile APP is directly synchronized to the server and displayed on the web:

Technical features:

Reliable:

• use private communication protocols to ensure real-time unimpeded data links
