Self-service terminal after advancing tide of information, but also gradually gaining in popularity all around us, such as hospital registration, payment, print report card, banking, telecommunications and self-service for business, self-ticketing, self-service ordering take a number, self-service check-in, etc. . Self-service has brought us in addition to reducing waiting in line outside, their advantage 24 hours of unattended operation is also increasingly subject to the owners and users of all ages.
Most of the traditional self-service equipment developed based on X86 architecture computer systems running Windows, because of its bulky size, high cost, high power consumption, easy-virus system crashes and other issues criticized by everyone, also known as self-service equipment more batch universal stumbling block.
It happens, ARM's performance has become increasingly powerful, easy to use interface of its software partner Andrew system is also familiar to us, and gradually occupy a certain share in the field of self-service equipment.
ARM for its low cost, low power consumption, small size, high stability advantages and can hit home to break the stumbling block self-service equipment, to achieve a broader self-help, so that our life and production can be more convenient, more efficient, lower cost.
Here, the author OK3399-C ARM motherboard (right), and four generations of X86 i3 motherboard (left), for example, the cost of hardware, software costs, heat consumption, volume, maintenance costs make a comparison of these five aspects:
▲ X86 Motherboard
▼OK3399-C
1, the hardware cost
X86, i3-4025U CPU, 4G RAM, 64GB SSD configuration, the basic configuration can ensure smooth running Win10 system, the price of around 1200; and ARM, RK3399 CPU, 2G RAM, 16GB ROM is arranged, Android system running very smooth, even application of face recognition can be done, priced at 899RMB.
From a hardware costs, you can save at least 300RMB per device cost.
2, the system cost
license fee Win10 system is about 750, although we all want to avoid the cost of this part of the way, but after all, there are legal risks.
ARM motherboard can install Android system, Android system is a free open source system, to avoid legal risk piracy system brings.
3, power dissipation
I3-4025U consumption of about 15W, and OK3399-C motherboard typically consuming about 3 ~ 5W (here said to account for heat or power-based). Due to the high calorific value of X86, and needs cooling fan, which brings challenges to the design of the machine. Most of these machines are placed in open public places, dust, damp, mosquito protection you need to consider, and chassis fan openings do not conducive to the above-mentioned protection design, a long time to clean up needs to be done to dismantle the machine chassis, in order to avoid fan stall risk of crashes.
ARM low power consumption, heat generation is small, no cooling fan, the chassis can be made fully closed, reducing maintenance.
Not only the heat of the high power consumption problem, the power adapter must also requires more power, high cost, large volume.
X86 motherboard corresponding large power adapter
4, the volume
on the market X86 ITX motherboard minimum size 17cm * 17cm, coupled with the power supply, cooling unit, the overall volume of ARM board than doubled.
Equipment small, lightweight, space-saving will bring , will reduce the cost of transportation and installation of equipment, to provide a better solution batch applications.

5, operation and maintenance costs
Maintenance costs come from labor costs, hardware maintenance and software maintenance incurred, hardware maintenance costs, the cost of customer intelligence.
Install and deploy applications for Windows systems, each device each time at least 40 minutes to complete, the intermediate process requires human intervention. In contrast Android application installation and deployment of the system up to 10 minutes to complete, the operating system and applications can be packaged into a mirror, a key installation, a single piece of equipment maintenance cost savings of 30 minutes.
By comparing several aspects of the above analysis, we believe we understand the advantages of ARM board kiosk applications.
Of course, the replacement of the Android system development there are drawbacks or short-term pain, such as Windows-based application code developed no reproducibility, need to completely re-developed test before; hardware boards of varying quality and so on. This is also the current challenges facing the ARM application, but with the ownership of Android phones more than the PC, who is also increasing its APP development, recruit a threshold and cost Android APP JAVA development engineers than Windows C # development engineers more low. Further, the ARM board functions and interfaces are also gradually universal compatibility stronger. Feiling such as embedded deep plowing in the field of industrial ARM board manufacturers for many years more and more, buy a reliable ARM board is no longer difficult.
I believe there are cost-effective introduction of ARM board, will help the market self-service terminals cake will be bigger and bigger, our lives, the production will be more convenient and intelligent.
