1. Background

With the continuous development of economic and urbanization, as a basis for

public transport, elevator’s basic function is to bring people to destination floor or area

smoothly and safely. In this case, safety has become a most concerned problem for

passenger. However, elevator’s complex system, high security requirements and its

special purpose determines to the elevator with dispersion installation, many


-----------------------------------------------------------------------------------------------------------


monitoring points, hardly wiring, long communication distance, and harsh operating

environment. Therefore, how to ensure the safety, minimize looses to let the passengers

have a nice experience has gradually become a big problem of government regulators,

elevator manufacturer, elevator suppliers, elevator maintenance service providers,

real‐estate developers, residential property.

Caimore wireless GPRS/3G/4G DTU for elevator remote management system is a

designed control & management solution for monitoring elevator operation safely. Its

core function is transferring all the running status of the elevator to central monitoring

center quickly and accurately, in order to learn the real‐time operating conditions to

reflect the security risks. It also be able to handle a timely response in the event of

failure, in order to accurately locate the fault area elevator, troubleshooting win

precious time.

2. Solution introduction

This solution can be implement to monitor each elevator’s operation status in

real‐time, such as the reached floor, cage’s running state, door is open or closed,

elevator’s speed direction and so on. Once there is any malfuction, the system will send

out the alarm message timely in order to ask the maintance staff to do the repair timely.

The system also will record the fault information; accurate positioning and real‐time

feedback the fault in order to easy troubleshoot and solve problems.

5. Applications and functions

1) Connected devices: each elevator control panel is connecting with Caimore

GPRS/3G/4G wireless DTU by RS232/ RS485 or Ethernet;

2) Server: To install a rack server or server cluster in the central monitoring center,

which will be a server of Caimore elevator remote monitoring software system to get

the all the serial data from Caimore GPRS/3G/4G wireless DTU.

3) Built a data channel: apply a fixed IP address for the server, and open a new port


-----------------------------------------------------------------------------------------------------------


number for it too from the switch router which has been connected to Caimore

GPRS/3G/4G wireless DTU. This is the data channel for Caimore GPRS/3G/4G wireless

DTU transparent to transfer all the serial data from the elevator control board. Each DTU

will have its unique device number to identify the connected elevator.

4)data transmission: When DTU is enable, it will built up a transparent transmission

channel between the central monitor center and filed device by GPRS/3G/4G wireless

network. Then it can seal and transfer all the real time serial data from the elevator to

data server software for real time acquisition, processing, control and statistics.

5) Display information: the system can be accessed by a large TV wall. All the data

can be displayed on it to facilitate the staff to check and management. Such as the

elevator cage position, direction, speed, door status, passenger waiting time, run time,

energy consumption, elevator fault and so on.

6.Why CAIMORE

Caimore Communication devotes herself to IOT and the industrial automation

fields, provides wireless products and video surveillance solution for remote site.

The elevate smart remote monitoring system uses wireless GPRS/3G/4G DTU to

achieve the whole system network operations, management and monitoring role which

save expenditure for early period network layout and development cycle time.
