The contactless and convenient elevator solution launched by STEP has received strong market response and customer demand has increased significantly. This article focuses on the detailed introduction of this solution, specifically from the program advantages, system architecture, installation and commissioning, user use of these aspects to explain.

Program Advantages

1. follow the habit of taking the elevator, easy for users to use.

2. Support immediate access to the elevator, while user rights management can be carried out according to the needs of the scene (such as residential, hotel, etc.).

3. According to the needs of the scene, it can provide quick functions, such as: "one key to work" function in office buildings, etc.

4. Only need to set up an IOT gateway in the server room.

5. Support 4G and Ethernet two kinds of Internet access mode. Ethernet mode is recommended in the case of network cable arrangement in the server room, with no traffic cost.

6. value-added services such as elevator health degree report can be provided later.

7. Adopting an independent IOT interface to realize data interaction without affecting the safe operation of elevators.

8. Private encryption protocol is adopted to ensure network security.

System architecture for contactless elevator solutions

System Architecture

1. The elevator gateway is connected with the main control board through the IOT communication port and installed on the side of the control cabinet in the machine room.

2. The elevator gateway and the main control board communicate with each other in both directions through the IOT communication port. On the one hand, the gateway collects elevator operation data to realize the regular elevator monitoring function, and on the other hand, it sends the elevator calling command from the smartphone → cloud platform at the user end to the main board.

3. The "elevator cloud" platform acts as the service end of the smartphone and the equipment in the machine room at the user's end.

4. No electrical connection with the elevator control bus, which does not affect the safe operation of the elevator.

5. The elevator gateway supports remote program update, and can be remotely upgraded and debugged according to the on-site situation.

6. When the machine room has Ethernet Internet access conditions, the Ethernet gateway ESDT200-ETH is recommended; when the machine room does not have Ethernet Internet access conditions, the 4G gateway ESDT400 is recommended.

Installation and commissioning

1. Submit application for network access and fill in terminal access information.

2. Use "STEP Elevator Cloud" APP for function debugging.

3. Generate user QR code in batch and post it through STEP elevator cloud platform according to the site layout requirements.

How to use WeChat applet

1. Open WeChat, scan the QR code outside the elevator lobby, and open the "STEP Elevator Cloud" app.

2. The passenger's current floor will be automatically brought out and directly enter the call interface.

3. Passengers will click the up-call and down-call buttons according to the floor they need to go to, and then register the instructions inside the car.

How to use the mobile app

1. Download and install the "STEP Elevator Cloud" APP in your mobile APP store.

2. Open APP and scan the QR code outside the elevator hall.

3. The passenger's current floor will be automatically brought out and directly enter the call interface.

4. Passengers will click the up-call and down-call buttons according to the floor they need to go to, and then register the command inside the car.

5. When the elevator arrives, the user enters the elevator and waits to reach the destination floor.

6. The user arrives at the destination floor, and this ride ends.
