QUNMAO wall-mounted touch query all-in-one machine in the public hall query machine deployment scenario
In the government hall, hospital outpatient service, hotel front desk, shopping mall atrium, where people come and go every day, "let visitors check and order by themselves."Touch query all-in-one machineIt has become the first alternative to manual guidance. AsTouch query all-in-one machine, query machine, touch query terminalAs the core source factory, QUNMAO from the screen, motherboard to the whole structure of the whole process of self-research and production. From the perspective of the manufacturer, this article tells what the inquiry machine is, how to choose the form of the inquiry machine, how to touch it, how to read the parameters of the inquiry machine, and what to confirm before placing an order.
Query machine(The full name is touch and query all-in-one machine, also calledTouch inquiry terminalInformation inquiry terminal) is a self-service information terminal with touch interaction as its core function: visitors can touch the screen to complete information retrieval, business inquiry, navigation and navigation without manual intervention. The query machine solves, it is "where to do, how to do, who to ask 」.
Different from ordinary displays, the touch inquiry all-in-one machine integrates the display module, touch frame, industrial motherboard, operating system, shell and heat dissipation height into a complete device, which can be used immediately after power supply, and supports wall-mounted, vertical, embedded and other installation methods. This is also the reason why query machines are deployed in large numbers in hospitals, government affairs, transportation, supermarkets and other scenes-a query machine is a self-service window.
The global selection of Kiosk categories (inquiry machine, ordering machine, queuing machine, interactive table, etc.) can be seen first.Self-service terminal (Kiosk) full product line guideThis article focuses on the query machine body.
The three types of equipment that are most confusing when purchasing areQuery machineAdvertising machine (information release screen) and self-service terminal. They are similar in appearance, and the query machine is completely different from their core task:
| Comparison dimension | Touch query all-in-one machine (query machine) | Advertising machine/information release screen | Self-service business terminal |
|---|---|---|---|
| Core task | Visitors self-query information, navigation, business guidance | One-way broadcast advertisements, announcements, and promotional content | Handling actual business: taking number, paying fees, registering and printing certificates |
| Interaction Modes | Strong interaction: touch tap, swipe, input | Basically no interaction, mainly to play | Strong interactive business logic: docking system, payment, printing, etc. |
| Typical equipment | Wall-mounted inquiry machine, vertical inquiry machine, K/L type horizontal inquiry machine | Elevator advertising screen, mall poster screen, canteen menu | Self-service number picking machine, self-service payment machine, self-service registration machine |
| Procurement focus | Touch experience, query machine form, system compatibility, software pre-installation | Brightness, playback management software, appearance | Business software docking, peripherals, stability |
The judgment method is very simple: just don't click on the advertising machine, click on the self-service business terminal that can handle affairs, and choose with the goal of "let people find, understand and find"Touch query all-in-one machine. Most of the projects are deployed in combination-the entrance of the hall is guided by the inquiry machine, and the service window is handled by the service terminal. The two are complementary.
Query machine form is determined by "installation position" and "use posture. QUNMAO currently produces six types of inquiry machines in mass production: conventional wall hanging, vertical, double-sided screen vertical, full screen, K-type and L-type, with screen sizes covering 32 / 43 / 49 / 50 / 55 / 65 / 75 / 85 / 98 inches.
QUNMAO 32 inch infrared touch wall mounted inquiry machine (model QM-C32XJ-BG)
The most common form of inquiry machine: wall-mounted, not occupying ground space, suitable for corridors, elevator halls, service desks and other positions. The body of the wall-mounted inquiry machine is about 55mm ultra-thin, equipped with universal horizontal and vertical hanging brackets, and also supports embedding in the wall. The most common 32-49 inch wall-mounted inquiry machine in public buildings mostly comes from this form.
Deployment Effect of Vertical Touch Inquiry All-in-One Machine in Shopping Mall Atrium
With the base floor placement, strong mobility, shopping malls, exhibition halls, offices are frequent visitors. Vertical inquiry machine base built-in wiring, overall anti-dumping, suitable for 43-65 inch large screen inquiry machine selection.
Double-sided screen vertical inquiry machine: front and rear double-screen, can serve two directions at the same time
The front and back screens, front touch query and back carousel display, can cover the two-way passenger flow, which is suitable for the deployment of inquiry machines at the "double-sided passenger flow" positions such as atrium, channel cross, and both ends of the counter.
Full screen inquiry machine: the screen is almost covered with the front, weakening the visual interference of the border
The screen is almost covered with the front, the border is very narrow, weakening the "machine sense", suitable for the exhibition hall, flagship store, government hall and other places with high image requirements. Full screen inquiry machine is usually matched with capacitive touch, and the appearance is more overall.
K-type horizontal inquiry machine: inclined plane structure, standing posture natural touch
Type K is the representative of horizontal inquiry machine: the screen is inclined upward, people stand at a natural angle to click, in line with the ergonomics of standing operation, is widely used in hospital guidance, government guidance, library search and other "standing" inquiry machine scene. See the structural parameters for detailsK-type horizontal inquiry machine product details。
L type horizontal inquiry machine: table type operation, suitable for overlooking use
The L-shape is closer to the "table/desktop" operation: the screen is flat or slightly tilted, and visitors click from the top. It is suitable for service desks, navigation desks, negotiation areas, and is also common in child-friendly and barrier-free scenes (sitting posture is available). See detailsL-type horizontal inquiry machine product details。
| Query Machine Form | Typical Scene | Common sizes | Installation method | Recommended Touch |
|---|---|---|---|---|
| Wall-mounted | Corridor, elevator hall, service desk side, stair entrance | 32-49 inches | Wall Mounted/Embedded | Infrared/Capacitive |
| Vertical | Shopping mall, exhibition hall and office hall | 43-65 inch | Landing | Infrared/Capacitive |
| Double-sided screen vertical | Atrium, aisle cross, counter ends | 43-55 inch | Landing | Front capacitance |
| Full screen | Exhibition hall, flagship store, high-end government hall | 43-65 inch | Wall Mounted/Floor Mounted | Capacitor |
| K type horizontal | Hospital guidance, government guidance, library retrieval | 32-55 inches | Landing (Inclined) | Infrared/Capacitive |
| L-type horizontal | Service desk, guide desk, negotiation area | 32-55 inches | Countertop/floor | Infrared/Capacitive |
Details of the choice of the form of the inquiry machine in the same scene-whether the hospital chooses the wall-mounted inquiry machine or the K-type, the shopping mall chooses the vertical inquiry machine or the double-sided screen-see the special article:How to Choose Sloped, Horizontal & Floor-standing, and Wall-mounted Information Kiosks? Form Comparison & Application Scenarios(Click to jump after publishing).
The touch mode is the first decision item in the selection of the query machine. QUNMAOTouch query all-in-one machineProvideCapacitive touchwithInfrared TouchThe two schemes have different principles and are each good:
| Comparison dimension | Infrared Touch | Capacitive touch |
|---|---|---|
| Working principle | Infrared emission/reception matrix on four sides of the screen, occlusion is positioning | Sensing finger capacitance changes, direct positioning of contacts |
| Touch Performance | Support 20-50 points at the same time touch, can wear gloves, available pen | Single-finger/multi-finger fine operation, smooth response, support gestures |
| Surface material | 4mm tempered glass, physically tempered Mores Class 7, explosion-proof and anti-glare | Glass fit, can do a full screen without border effect |
| Environmental adaptability | Not afraid of dust and oil, not afraid of gloves, public scenes more durable | Afraid of dirt and strong interference, suitable for relatively clean indoor |
| Cost and Maintenance | Mature structure, simple maintenance, controllable cost of the whole machine | The bonding process requires high requirements and the cost is slightly higher |
| Typical Scene | High-frequency public use in hospitals, government affairs, stations, supermarkets, etc. | Showroom, flagship store, full screen model, fine interaction |
The infrared touch query all-in-one machine supports multi-touch and glove operation, making public scenes more durable.
A word of advice:High-frequency public environment query machine priority infrared touch, image and fine interaction priority capacitive touch; When not sure, we support a prototype comparison according to each of the two schemes. The size of the inquiry machine is determined according to the viewing distance: 32 inches for 1-3 meters, 43/49/50 inches for 2-4 meters, 55/65 inches for the main position of the hall, and more than 75 inches for large exhibition halls -- QUNMAO inquiry machine covers 32-98 inches, and can be customized in full size.

This inquiry machine specification sheet is from QUNMAO product technical documents, and the parameters of the inquiry machine can be checked item by item. You need a complete query machine parameter table of 43-98 inches or other forms, and you can ask the sales for the corresponding model specification.
The inquiry machine is good or not, half depends on the hardware and half on the software. QUNMAO'sTouch query all-in-one machineThe following core software capabilities are supported at the factory:
Three points must be confirmed when purchasing the inquiry machine: whether our software can be pre-installed, whether the content can be updated remotely, whether the start-up and timing switch machine are supported by default-these three points directly determine the subsequent operation and maintenance cost of the inquiry machine.
Self-service inquiry area in hospital hall: multiple inquiry machines are deployed side by side to divert the pressure of front desk consultation.
The application of inquiry machine is very wide. The main query machine scenarios covered by QUNMAO cumulative shipments include:
The query machine form of each scene is different from the software collocation. Specific to the hospital, government affairs, shopping malls and other 12 big query machine scene how to match, can see the scene topic:Touch Query All-in-One Application Scenario Inventory(Click to jump after publishing).
As the manufacturing side, we have seen too many "query machine parameters look almost, with a lot of difference" project. SelectTouch query all-in-one machineIt is recommended to follow the following seven steps:
QUNMAO's own production line: assembly, commissioning and testing are completed in the factory.
As a source factory, QUNMAO supports customization of in-depth inquiry machines by project: appearance mold opening and color matching, body screen printing and Logo, startup screen, pre-installed software and system simplification, interface adjustment, inquiry machine size and form customization, and batch OEM / ODM labeling. The factory can receive the inspection factory and provide prototype confirmation before mass production. For B- side customers, direct dockingTouch query all-in-one machine manufacturer, the price, delivery date and after-sales service of the inquiry machine are all less intermediate links.
In 2026 [x month], QUNMAO completed a typical domestic hospital guidance project-deploying a 32-inch infrared wall-mounted type for the outpatient hall of [a tertiary hospital in a city]Touch query all-in-one machine QM-C32XJ-BG [N] sets in total.
The daily outpatient volume of this hospital is about [x] person-times, and the guidance desk queues up all the year round. Patients repeatedly asked "hang which department" "department in which layer", the same question to answer hundreds of times a day; paper guidelines update slowly, the old information is still misleading after the adjustment of the department. The hospital's goal is very clear: to divert repeated consultations to the inquiry machine and to change department information to electronic content that can be updated remotely.
After comparing with the schemes of [X] suppliers, the reasons why the hospital chose QUNMAO are concentrated in three points: the source factory can be inspected, the pre-installed hospital information inquiry software is supported, and the startup screen can be customized. Final configuration: QM-C32XJ-BG infrared touch wall-mounted machine [N], Windows version (i5 / 8G / 256G), pre-installed hospital information inquiry client, deployed in outpatient hall, clinical laboratory and pharmacy.
The equipment is wall-mounted and docked with the hospital intranet, and the content can be updated remotely. In the first month after launch, the number of repeat inquiries at the information desk decreased by approximately [X]%. The three most prominent points of the hospital's feedback are: the stability of infrared touch in public environment (it can be operated with gloves and wet hands), the maintenance-free experience brought by self-starting and timing switch machine, and the need for remote content update to avoid reprinting materials. After the acceptance of the project, the hospital added [Y] inquiry machines to cover the new hospital area.
Q1: capacitive touch and infrared touch how to choose?
Look at the use environment: the inquiry machine in high-frequency public environment gives priority to infrared touch, is resistant to dirt and gloves, and has a long service life.
