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.

3、System components
1) Elevator and its control cabinet;
2) Caimore wireless GPRS/3G/4G DTU will be value as a telemetry gsm modem to
transparent all the digital serial data from the elevator control cabinet;
3) GPRS/3G/4G sim card to provide wireless network;
4) Server and database;
5）Remote monitoring system software;

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.
