Vending Machine Wireless Management Solution
Based on 2G3G4G Industrial DTU
Key words: Industrial Wireless DTU, Industrial SMS modem, Vending machine, Remote
monitoring, Remote management

Abstract:
As a new convenience equipment, vending machines has gradually been accepted by
consumers. In recent years, people gradually realize that imperfect machine system: The
real‐time operating status can not be monitoring in time, either or can not be timely
replenishment operation, which affect the normal operation of the machine, and take a
great inconvenience for operators and consumers great. To end this, it was proposed a
idea to conduct network to monitoring vending machine, by analyzing the
characteristics of wireless network communications and applications vending machine
for analysis, using combined with wireless data transmission module and a relational
database to build a wireless network remote vending machine monitoring system.Use of
the communication mode with C/S (Client/Server) architecture, to establish data
communication between the vending machine and the server, combination the wireless
module & embedded module as the client that is responsible for collecting the
operation data from vending machines; and then implement the message processing,
uses a database to store and query capabilities on central server, to realize the system of
historical data queries. On the basis of encapsulated the transmission data and
response measures, and designed a workflow system to achieve the stable
communication. By monitoring the end user interface, it will intuitive reflect the vending
machine’s status and sales volume, and not only provide more timely reference for
replenishment operation, but also facilitate the staff to real‐time monitoring the
indicators of vending machine’s operating status.

System Architecture
Caimore vending machine wireless management system is consisted of vending machine,
industrial wireless DTU (SMS modem) and central server. Wherein, vending machine terminal
includes a read controller, electronic locks, and storage cabinet. People can purchase the required
goods at any time through vending machine. Caimore industrial wireless DTU series products can
built up a high speed; stable networking and data transmission channel by RS232/RS485 for vending
machine, and then transfers all the data back to enterprise cloud server by 2G/3G/4G network, so
that the enterprise can analysis the business and do some operation. Meanwhile, the operating
enterprise can remote supervised the running state of the vending machines, which are dispersed in
different locations, in order to reduce the cost of operation and maintenance.

----------------------------------------------------------------------------------------------------------System structure and main functions:
1.
To implement real‐time information sharing among vending machine, e‐commercial
company and customer, and high efficient distribution.
2.
To realize “24 hours” delivery service, and upload all the real time information to
enterprise cloud server.
3.
To link vending machine terminal with e‐commerical, courier companies,
networking company, UnionPay, and property, in order to exchange the lots of data.
4.
To achieve the centralized management of distributed vending machine terminal,
and real‐time control the running status, in order to rapid reduce the courier’s business operation
cost, and improve the service quality and operating efficiency of operators.
5.
The reliable operational data reports provide a decisioin‐making basis for operators
to improve the information level of logistics industry, and promote the rapid development and the
community‐based’s quick distribution.
6.
Site video monintoring, image capture, view the each positioning’s capture pictures
in order to storage the video evidence of man‐made damage to the vending machine.
7.
Wireless router communicated by wireless networking, absolve the wiring problems
and environment factors. As long as the single of cell phone is nomal, it can access into network
automaticly with the advantage of installation easily and flexibly. According to simply web page
configuration, wireless router can dial‐up automatically and send out the connection request, and
rapid to link with the web‐basid router management platform easily.
System core product:
This system’s core device is Caimore industrial wireless DTU (SMS modem), which is a
transparent transmission product build up a transmission channel between vending machine and
central server.

----------------------------------------------------------------------------------------------------------2. Three-tier system protection: software protection+WDT + CPU built-in protection.
3. UIM / SIM card ESD protection: 1.8V/3V/5V standard putter user card interface,
built-in 15KV ESD protection.
4. Serial ports ESD protection: serial port RS232/ RS485/ TTL/RS422, built-in 15KV
ESD protection.
5. Metal shell: anti-radiation, anti-interference; shell and system security isolation,
lightning protection design; meet the power requirements of safety regulations;
protection rating IP41; particularly suitable for harsh industrial control environments.
6. All wireless modules are certified by the CGD or FCC certification or CE
certification.
7. Automatically obtain DNS: Automatic access to DNS, no longer need to manually
configure the input DNS; avoided the serious DTU crash resulted from wrong choice of
the abnormal DNS server.
