Query Machine Hardware Configuration Guide: Motherboard Memory Storage System | QUNMAO Source Manufacturer

OpeningIt is also a 43-inch inquiry machine, why can the quotation be twice as bad?

Most of the time, the difference is not in the screen, nor in the shell, but in the four things you can't see: motherboard, memory, storage and operating system.

Overseas buyers, system integrators and software developers often find that the same size, the same appearance, the price varies greatly when comparing the quotations of inquiry machines. Disassembled, the difference almost all falls on the hardware configuration. If the configuration is selected well, the equipment can run quietly for many years. If the choice is wrong, either it will cost more money, or it will restart frequently after a few months on line, the storage will be full, and the software will not run.

AsSource manufacturer of China touch query all-in-one machine, QUNMAO Qunmao (its brand Qtenboard) Design the whole machine and select the motherboard scheme by yourself, so you can give the configuration from the software load instead of just providing a "standard". Below K-type touch query all-in-one machine Take the specification data as an example, one by one.

01Why is the configuration the most different part of the quotation?

The screen size and case are visible on the page, but the motherboard, memory, storage and system are hidden in the body. It is precisely these parts that determine the stability and life of the equipment. The three most common pits in procurement:

• Only look at the CPU model, not the heat dissipation design and device grade.
• The storage capacity is sufficient, but the impact of continuous writing on life is not considered.
• The system was wrong and the customer's existing software could not run, which was discovered only after the arrival.

02Look at the load first: how much is the software of the inquiry machine?

The configuration is to be pushed back from the software, not from the parameter table.

The software of the inquiry machine can be roughly divided into four gears. First judge which file your project belongs to, then talk about configuration:

Also consider the "operating mode": whether the device is on all day, how many logs are written every day, and what the ambient temperature is. Our inquiry machine specification supports power-on self-start, one-key start-up with light and custom switch-on time. The vertical self-service terminal supports 7 × 24 hours of continuous operation. Different operation modes have different requirements for configuration. See complete product line Self-service machine product catalog。

03Motherboard: How to judge whether it is "industrial control grade"

The motherboard is the core of the query machine. The purchaser does not need to understand the circuit, but can use the following table to ask the supplier questions:

Qunmao inquiry machine supports power-on self-starting and one-key starting. The applicable environment is temperature 0~55 ℃, humidity 10% ~ 90% RH, standby power consumption not more than 1W, rated power 43 inches not more than 85W, 50 inches not more than 95W. Before the equipment leaves the factory, it must pass the aging test of the whole machine to screen out the early failure.

04CPU and memory: how big is enough, how big is waste

Our specifications have two main lines, corresponding to Android and Windows:

How to choose memory

• 2GB：Suitable for pure display and lightweight pages, it is a Android entry configuration.
• 4GB：Consider when pages are heavy, multiple apps are running at the same time, or you need a smoother browser experience.
• 8GB（Windows）：A common starting point for running Windows systems and station software.

The allocation is too high and too low, each with a cost.

If the configuration is too low, there will be Caton, slow page switching, application recycling or even restart by the system. If the configuration is too high, the cost, power consumption and heat generation will be increased. However, equipment in public places needs to be turned on for a long time. Heat generation is precisely the enemy of stability. So the goal is not "highest", but "just have margin".

configuration of different sizes is recommended, we in "K-type horizontal inquiry machine screen size and configuration how to choose" with L-Type Horizontal Query Machine Screen Size and Hardware Configuration Guide The specific models and parameters can be referred. K-type inquiry machine product page。

05Storage: How to Calculate Type, Capacity and Life

Difference between eMMC and SSD

The Android solution usually uses eMMC storage, and the Windows solution usually uses SSD. Both have their own characteristics in speed, write durability and cost: SSD is faster, better durable and more expensive; eMMC is low in cost and small in size, suitable for light loads. Our specification configuration is: Android version 32GB storage, Windows version 128GB SSD.

Capacity Accounting: Using Formulas, Not Feeling

Video footage is the content that takes up the most space. The estimation method is simple:Occupied space = code rate × duration ÷ 8. The following are estimates:

In addition to systems, applications, logs, caches, and backups, there is room for total capacity. For example, 10 10 10-minute 1080P videos require about 6GB. The same amount of 4K video, about 19GB, is close to the conventional usable range of 32GB storage and requires caution.

Write Lifetime: The Neglected Killer

The life of the storage is mainly consumed by continuous writes, such as logs, caches, and temporary files. It is recommended to do three things: set log rotation and size limit; Clean the cache regularly; Reserve enough remaining space to avoid long-term full.

06Operating System: Android or Windows

The choice of system depends first on where your software can run.

When selecting a model, one of the most practical approaches is to first confirm the software developer or customer's existing software operating environment. If the customer's software only runs under Windows, choosing Android is meaningless. If it is only a web page and content display, choosing Windows will increase the cost and maintenance work.

programs used in public places, you can refer Station Information Inquiry Machine Solution, which gives configuration recommendations by Android and Windows lines.

07Interface and peripheral planning: first count clearly what to connect

Interface in Specification

Peripherals: Optional vertical self-service terminal

Points that need to handle class business often need to connect peripherals. Take our vertical self-service terminal as an example: the screen is 21.5 or 32 inch vertical screen, the resolution is 1920 × 1080, the touch can be selected by capacitance or infrared, the system can be selected by Android or Windows, the card reader, encryption keyboard, slip printer and code scanning equipment can be selected, the power supply is AC 110-240V, 50/60Hz, and the continuous operation is supported for 7 × 24 hours. See details Vertical self-service terminal with 27 inch touch self-service inquiry terminal。

Make an "interface budget table"

Planning principle: the number of USB ports should be left with allowance; When there are many peripherals, consider selecting more interfaces. Special interfaces such as serial ports (such as RS232) are required, which should be proposed in the early stage of the project for customization.

08Remote management: whether it can be managed or not determines the operation and maintenance cost.

As the number of equipment is large, the operation and maintenance cost depends on whether it can be managed remotely.

• Online monitoring:Check whether the equipment is online and running normally at any time.
• Remote operation:Remote restart, adjust volume, switch screen schedule.
• Bulk upgrade:Bulk update software and content via OTA.
• Time switch machine:Automatic switch according to business hours, saving energy consumption.
• Log export:Easy to locate problems and audit.
• Offline cache:The basic information can still be guaranteed to be available when the network is interrupted.

These functions are closely related to the hardware configuration: self-starting, watchdog, storage margin and system stability, which are the basis of remote management. Most of the problems at the software level can be handled remotely; physical failures of the motherboard and touch screen need to be handled on site.

09Seven common configurations of stepping pits

10Third gear configuration table (based on specifications)

The above is subject to the specifications of each model, and the project can be adjusted as required. The touch of 43-inch and 50-inch models is capacitive G G and 20 points, and the screen is 1920 × 1080. Please refer to the corresponding specifications for details.

11BOM and OEM/ODM Key Points of Overseas Projects

• The specification is consistent with the material:How to manage the prototype, batch products and substitute materials should be clearly written at the contract stage, and it should be agreed that "prototype shall prevail".
• Life cycle and long-term supply:Related to the late replenishment, expansion and maintenance, to understand the main components of the supplier.
• Configuration customization:Motherboards, memory, storage, interfaces, peripherals, system images and pre-installed software can be customized by project.
• Power supply and certification:The power supply of vertical self-service terminal is AC 110-240V, and the specification of 43/50 inch inquiry machine is AC 110-220V. The local voltage should be checked and confirmed in writing in the early stage of the project. Device certificates are available at Qualification Certificate Page View.
• Spare parts and aftermarket:Confirm common spare parts list, remote support method and response schedule.

12QUNMAO · Qtenboard Jakarta Business Hall Project: 30 sets, two configurations, 6 weeks delivery

The core of this project is to "not allow customers to choose all Windows", nor to "choose all Android", but to make each device configured just right.

Project Overview

Customer's core demands

Customers hope to deploy unified inquiry equipment in many business halls across the country for package and business inquiry, network information and business guidance. At the same time, in the handling areas of a few flagship business halls, they need to run local Windows clients and connect card reading and printing equipment. The customer's IT team initially wanted all devices to be Windows, on the grounds that the team was familiar with the software and that there was no risk of software compatibility.

Our approach: do load analysis first

We did not directly agree or object, but together with the customer's IT team, we listed the software load of each point: most points just open the query page and display the content in the browser, belonging to file B; Only a few points in the processing area need to run local clients and connect peripherals, which belong to file d.

The conclusion is that the B- gear point can run smoothly with the Android version, with lower power consumption and cost, and easier centralized management through the cloud. The D-gear point uses the Windows version to ensure compatibility between local software and peripheral drivers. It was finally determined to be 24 Android and 6 Windows. The two configurations are exactly the same in appearance, screen and touch, and there is no difference for users.

Six Week Delivery Pace

Problems Encountered in the Project and Handling Methods

1. browser kernel is compatible with the page

The customer's query page has certain requirements for the browser version. In the second week, we used the customer's test page to complete the compatibility test on the Android prototype. We found that some page elements were not completely displayed in the default browser. Then we negotiated with the customer's development team and made minor adjustments to the page. At the same time, we fixed the browser scheme in the mirror image to avoid differences caused by future upgrades.

Peripheral joint debugging of 2. Windows points

The 6 devices in the processing area need to be connected to card reading and printing devices. At the factory stage, we connect the customer's peripheral equipment to the whole machine for joint debugging, confirm the driver, instruction and paper shortage prompt, and then mass produce, so as to avoid finding that the peripheral equipment is incompatible with the system only on site.

Unified mirroring and remote deployment 3. 30 devices

The business halls are distributed in different regions and cannot be debugged by our engineers shop by shop. We have made a unified system image and configuration template in advance, set up a time switch machine according to business hours, and uniformly publish content through the cloud background. After the installation is completed, the online status of the equipment is checked in batches by remote means to minimize the amount of on-site debugging.

Project Results

• To the customer:In the business hall, self-service query package, business and network information, the equipment in the processing area can be connected to peripherals to complete the processing.
• For business hall staff:Repetitive consulting is reduced and you can focus on business that needs to be handled manually.
• For the information sector:The two configurations are managed in a unified manner, the content is published centrally, and the device status can be viewed remotely.

30 sets of equipment were delivered within 6 weeks and put into use in each business hall.
