Self-Service Car Wash

Machine Automation

Taiwan

Project Introduction:

With rising wages and 24/7 service expectations, a leading chain of gas stations in Taiwan decided to

create a self-service car wash. This required that the system was fully integrated with payment systems

such as credit cards, cash cards, Modex, stored value cards and membership cards. With the UNO-2170

and FPM-3150, the application has been successful, and the customer is already busy developing new

features.

System Requirements:

The Self-Service wash car system had to be connected to a wide range of equipment like: card readers,

bar code scanners, cash registers and central servers. The customer desired to build a reliable automation

system that could withstand high temperatures and resist spilled water from the washing machine.

Connected to an Ethernet network, the system would communicate with a host system and banks for

transactions. And with an outdoor installation in sunny Taiwan, it was necessary to have an operator

interface with high brightness so that it was visible in strong sunlight.

System Description:

The first attempt failed because I/O port limitations made expansion impossible. UNO-2170 solved that

problem, and is now the core platform in the system. All payment systems and readers such as the cash

operator pays, UNO-2170 can start the PLC that controls the car wash. All records are temporarily stored

in UNO-2170 and periodically passed to the gas station’s host system. Through the local Ethernet network,

all records can be exchanged between the central control room and gas station’s host system.

The car wash had to connect with the POS server in the gas station, and Advantech products were also

applied here. IPC-610 was used for the chassis, while PCA-6180 was used for the CPU card. IPC-610 is a

19” rack mounted industrial computer chassis for mission-critical applications. This unit can accommodate

a 14-slot PCI/ISA bus passive backplane or a standard ATX motherboard and supports versatile power

supplies. A lockable door in the front secures the unit from any unauthorized access. One hot-swap filtered

cooling fan maintains positive air circulation through the whole chassis. IPC-610 can withstand shock,

vibration and dust.

In the first phase of this project, customers pay and get a code from the cashier in the gas station.

This code is then input on the FPM-3150 touch screen, which starts the car wash program. But since

this requires interaction with a cashier, it is not 100% unmanned. With the first phase already running

successfully, the second phase will be to create unmanned payment facilities at the car wash. This

means using the remaining COM ports of UNO-2170 to link with a credit card reader, the cash register,

membership card reader, prepaid card reader and receipt printer. There will also be a sensor to detect,

greet and get visitors quickly started with their car wash.

Project Implementation:

Conclusion:

As a controller, UNO-2170 quickly proved to be a smart choice. The high temperature tolerance meant that an outdoor

application would be no problem, and the compact size facilitated installation in the same enclosure as the display. Vibration-

resistant storage ensured that the operating system could run reliably. And UNO-2170’s flexible expansion options provided

enough ports for all the planned device connections from PLCs, bar code readers, and a broad selection of payment systems.

With Visual Basic programs in Windows XP on a CompactFlash disk, the system is easily updated. Not using a proprietary

language means program development is easier, and upgrading of the OS in the field is simply a matter of replacing the

CompactFlash disk. For program updates, it is possible to connect with UNO-2170 through the Internet and upload the

changes. Downtime is not an issue.
