Many purchasers look at the price first and then want to configure the selection. As a result, only after the equipment arrived did they find that the size did not match the on-site moving line, the touch scheme did not cope with the environment, and the rework cost was much higher than the extra money spent during the selection. When we allocate goods to system integrators, we often receive such rework inquiries: the original L-type horizontal inquiry machine size cannot fit into the narrow corridor, the touch scheme fails in the condensing environment, and the Android standard cannot connect to the hospital's business system. This guide doesn't talk about product promotion, only one thing--L-type horizontal inquiry machineHow to select the hardware configuration according to the actual scene to reduce the rework probability before placing an order.
QUNMAO L type horizontal inquiry machine mass production real shot: different size segments side by side, 50 inch standard gear main model
Selection do not look at the parameter table first, first answer three questions:Who is using it?-Single operation or multi-person onlookers?Where to put it?-- Front desk narrow space or showroom open area?What system?-- Light-weight query or complex business system? These three questions correspond to the following three sections: size, touch control and motherboard, which are also what we do for integrators. L-type hardware configuration Fixed opening at the time of the program. The question was answered clearly, and the configuration table was only matched. If the problem is not clear, no matter how beautifully the parameters are piled up, it will be reworked. According to these three questions, the size, touch control and main board of the L-type horizontal inquiry machine will be explained thoroughly respectively.
About L-type inquiry machine sizeThe common question is "can it be bigger". The answer is: the transverse table structure of the L-type horizontal inquiry machine itself has physical constraints-no matter how large the size is, the ergonomics of the table body bearing and standing touch will deteriorate. No matter how small the size is, it will lose the advantages of placing data and handling documents on the horizontal table. The 43-inch and 50-inch segments are a reasonable range for taking into account structural stability and use experience in this form, not capacity constraints. The first step in choosing the size is to go back to the scene and look at the width of the moving line, not the size of the screen.
It is suitable for single-person operation such as front desk inquiry, navigation desk and corridor node, and the moving line is narrow. The 43-inch body is narrower, the table top is smaller, and it is placed against the wall or attached to the column without blocking the road.
Schematic diagram of a 43-inch typical scene: the front desk guide desk is operated by a single person, with a narrow fuselage and no moving line.
It is suitable for exhibition hall interaction, lobby inquiry, waiting hall and other open spaces, where many people may watch the same screen. The 50-inch screen has a longer visual distance, and the information density on the page can be higher.
50 inch typical scene schematic: exhibition hall/lobby open space, many people can watch at the same time
Project Background:The outpatient hall of a 3A hospital in Shenzhen initially planned to purchase all 50-inch L-type horizontal inquiry machines on the grounds that "the hall is eye-catching and clearly displayed". After the QUNMAO project team entered the site for survey, it was found that the clear width of the outpatient corridor was only 1.6 meters, the operation area in front of the equipment was less than 900mm after the 50-inch fuselage was put in, and the wheelchair could not be rotated, which did not meet the barrier-free acceptance requirements.
QUNMAO solution (divided by point):
Landing results:The partition mixing scheme passed the barrier-free acceptance of the hospital, the moving line did not block the road, the single-point budget decreased, and the self-service usage rate of inquiry was stable after the consultation. QUNMAO is subsequently copied to the floor point of the inpatient department of the hospital according to the same scene standard.
Note: The customer name is desensitized according to the project file; The 43/50 inch size combination and the above parameters are QUNMAO's real delivery practice, and the project team can apply for site survey.
The touch scheme of the inquiry machine should not only look at the "touch points" on the parameter table, but use "what is the environment" to select: the touch layer of the L-type horizontal inquiry machine is directly facing the public, and the cost of selection errors will be enlarged after the opening of the library.
Project Background:At the beginning of an exhibition hall project, the surface acoustic wave scheme was chosen cheaply. After the opening of the exhibition hall, the condensed water of the air conditioner condensed on the screen. The touch failure rate increased with the humidity, and the on-site wiping could not be cured. After taking over, QUNMAO will re-select the type according to the actual temperature and humidity conditions of the exhibition hall.
QUNMAO solution (change G G capacitor seal protection):
Landing results:After replacing the capacitance scheme, the touch failure rate will return to zero, and the opening acceptance will pass once.
Lesson:The environmental adaptation of the touch scheme is more important than the unit price. QUNMAO will actively dissuade inappropriate proposals during the proposal communication phase-we would rather do one less order than rework after opening.
Indoor scenes do not need to blindly pile high brightness. According to the real parameters of the QM-C50XJ-P, ≥ 300cd/m has satisfied the clear visibility under conventional indoor lighting. When the brightness is stacked above 500cd/m, the cost and power consumption will rise, and it is easy to see directly for a long time. In terms of resolution, the actual perception of 1920 × 1080 on a 43/50 inch screen is sharp enough-the viewing distance of human eyes in this size segment is usually 0.8-1.5 meters, and the perception difference between 1080P and 4K is not obvious, so it is not necessary to match the parameters well. L type horizontal inquiry machine brightness and resolution selection, the core is "enough, not waste".
There is only one criterion for judging the motherboard configuration of the all-in-one machine: how complicated your content is. The selection of the main board and system of the L-type horizontal inquiry machine is essentially a choice between "sufficient" and "docking business software.
Taking QM-C50XJ-P as an example, Android 11 system, RK3566S quad-core A55 (up to 2.0GHz) and 2GB 32GB can stably support inquiry/navigation applications: graphic browsing, video playing, form filling and remote publishing are all within the scope of capability. Support power-on self-starting, time switch machine, third-party APK installation, suitable for most exhibition halls and public space projects.
When it is necessary to connect to the hospital HIS system, run special software for government affairs, or use a professional content management platform, the compatibility of the Android will reach its peak-these software are usually only available in Windows versions, and Intel solutions must be Windows at this time. In the early stage, the software docking requirements are not clearly asked, and the cost of upgrading in the later stage is much higher than that of choosing the right one from the beginning.
Project Background:At first, a government affairs hall project was placed according to the Android standard (RK3566S GB/2GB 32GB). Later, when docking the government affairs system, it was found that the special declaration software had only Windows version and could not run Android. If the web page version is reformed, data security and control compatibility will not pass the government acceptance.
QUNMAO solution (upgrade Windows Intel hardware platforms):
Landing results:After replacing the Windows platform, the service system will be installed at one time, and the hall will realize the whole process of "self-service application material printing" unattended.
Lesson:The software docking requirements should be confirmed in the preliminary plan communication stage. QUNMAO will take the initiative to ask "what software to run on the equipment" before quoting, which can save the rework cost in the later period.
The deployment of multiple government affairs halls is indicated: this kind of scenario usually requires Windows scheme docking service system.
The following table is summarized from the real mass production configuration such as QM-C50XJ-P, covering the three gears of L-type horizontal inquiry machine: entry, standard and high-end, not theoretical parameters:
| Configuration item | Entry-level model | Standard file (QM-C50XJ-P) | High gear |
|---|---|---|---|
| Applicable size | 43 inch | 50 inch | 50 inch/custom |
| Touch scheme | Capacitor G G 10 points | Capacitor G G 20 points, accuracy ≤ 2mm, life 60 million times | Capacitor 20 points/infrared optional |
| Transport Storage | 2GB 16GB | 2GB 32GB (upgradeable) | 8GB 256GB |
| System | Android 11 | Android 11（可选 Windows） | Windows Intel i5 |
| Networking method | WIFI network port | WIFI(2.4G 5G) Bluetooth 100 M Network Port | Gigabit port WIFI optional 4G |
| Typical Scene | Front desk inquiry, guide desk | Exhibition hall, lobby, office hall | Government business systems, complex software |
| One word selection | Only do light query, limited budget | Most indoor projects directly | Must be docked with professional business software |
how to use this table:First look at the typical scene list and take your seat, then confirm the system file according to your software docking requirements-this is it. L-type horizontal inquiry machine configurationThe general logic summarized from the actual supply can be directly used by the integrator to communicate with Party A. There is no "the more expensive the better" in the table, only "whether it is suitable or not".
Back to the first three questions-where to use, for whom, and what system to connect. If these three questions are answered clearly, the answers to size, touch control and mainboard will naturally come out: 43-inch capacitor Android is used for single operation in narrow space, 50-inch capacitor Android is used for open crowd watching, and professional software will be Windows. Parameters are the last step, not the first.
Pre-delivery quality inspection schematic: touch accuracy, display and structure shall be inspected one by one, and the test data shall be provided with the delivery report.
In addition to 43 inches and 50 inches, can you customize other sizes of L-type horizontal inquiry machine?
43/50 inch is the mass production standard section of L-type horizontal inquiry machine, with the shortest delivery period and the most complete accessories. Other dimensions are limited by the physical limitation of L-shaped table top structure, and the scope of change is limited. If there is a requirement for non-standard dimensions, we can know our customization and OEM solutions, and determine them after evaluating the feasibility and cycle.
Capacitive touch and surface acoustic wave touch, the failure rate is really much worse?
The difference is mainly in environmental adaptation: capacitor G G is designed according to 60 million touch life in conventional indoor environment, with low failure rate; Surface acoustic wave is afraid of condensed water and dust, and the failure rate will obviously increase when the environment is not up to standard. This is exactly the lesson of the condensate case in the front exhibition hall-when selecting the type, first evaluate the environment and then talk about the technology. QUNMAO's L-type horizontal inquiry machine will confirm the touch plan according to the on-site temperature and humidity report before delivery.
Is the standard Android plan sufficient and can it be upgraded to Windows later?
Query/navigation/video applications, Android standard is fully sufficient. If you want to run Windows special business software later, the upgrade of the software layer cannot be realized by changing the system, and you need to replace Windows Intel models. Therefore, it is necessary to ask clearly "what software is running on the equipment" in the early stage to avoid rework of the whole machine in the later stage-this is also a question QUNMAO must ask in the scheme stage of L-type horizontal inquiry machine.
What is the approximate size of the project corresponding to the "standard file" in the three-file configuration table?
The standard file (QM-C50XJ-P,50 inch 2GB 32GB Android) is suitable for most 5-30 exhibition hall, lobby and office hall projects, and the single configuration and batch delivery are mature. For projects that exceed this volume or involve multiple simultaneous development and complex business docking, it is recommended to evaluate the scheme separately. QUNMAO will give suggestions on the sub-file combination of L-type horizontal inquiry machine according to the project.
