A good self-service terminal has a parameter table in appearance and a structure in bones. After the acceptance of the project, the equipment will stand in the hall for three to five years, running for more than ten hours a day-it is often the details that can not be seen at first sight that really determine whether it can "work decently:Where is the center of gravity, how to get the cable, how to install it on site, and how to repair it if it is broken?。

This article takes QUNMAO 50-inch L-type horizontal inquiry machine (model QM-C50XJ-P) as a reference to disassemble the structural design and make it clear. The technical data involved in this article are from the factory specifications and factory quality control process, the purchaser can request for review.

01The essence of stability: center of gravity, not weight

When you disassemble an L-type horizontal inquiry machine, you will find that its structural logic is very restrained: an L-type metal bracket, a slightly inclined touch panel and a metal body. There is no redundant decoration, each structural part is taking on the function.

To judge the stability of a horizontal inquiry machine, one should not only look at its weight, but also look at where its center of gravity falls. The L-shaped structure presses the weight of the whole machine very low,The projection of the center of gravity always falls within the support surface of the bracket-- This is a stable condition that can be deduced geometrically. Even if people lean on, press, or even climb by children at high passenger flow points, the equipment will not topple as long as the center of gravity is not pushed out of the supporting surface. The net weight of the whole machine is 26.5kg, which just shows that the stability does not depend on the stacking material, but on the structural design.

In the factory link, each equipment shall undergo structural quality control test: simulate the daily use load such as leaning and pressing, and check whether the connection between the bracket and the fuselage is loose, shaking or abnormal noise; At the same time, the packaging and transportation vibration simulation is carried out to confirm that the equipment is in good condition. The test method and judgment standard are provided by the factory quality control, and the purchaser can obtain the corresponding test records according to the project.

For a point with an average daily flow of tens of thousands of people, dumping is not only a loss of equipment, but also a hidden danger of personal safety and an operational accident of long-term shutdown. If you spend more time on the structure, you will have less risk on the scene.

02The "disappearance" of the line: behind the neatness is the certainty of operation and maintenance.

When many buyers see the L-type horizontal inquiry machine for the first time, they will notice that its back is very "clean"--The power cord, network cable and peripheral cable are all stored in the bracket and the wiring structure inside the body.The cable can hardly be seen outside. This is not for good looks, but for three things: acceptance, safety, operation and maintenance.

First, acceptance. Shopping malls, exhibition halls and government halls have clear requirements for space cleanliness, and equipment exposed by cables is often called back in the acceptance process. Hidden traces allow equipment and space to be integrated, making it easier to pass acceptance.

Plus security. Exposed cables mean the risk of tripping, but also the risk of failure to be scratched and pulled by cleaning equipment, shopping carts, and wheelchairs. After the cable "disappears", these two types of risks are physically compressed.

Finally, operations. Only necessary interfaces (Windows versions are DC × 1, USB × 4, RJ45 × 1, Audio × 1, VGA × 1, HDMI × 1) are reserved outside the whole machine. The interfaces are clearly defined, and there is no need to check cables one by one during maintenance-the time cost for fault location and replacement is significantly reduced. For B- side projects that require long-term operation, maintainability is the hidden operating cost.

03Ground placement: change deployment from "engineering" to "positioning"

L-type horizontal inquiry machine adopts L-type bracketGround PlacementThe size of the whole machine is 1117.8 × 648 × 87.45mm. After unpacking, put it in place, connect the power supply and network, and put it into use without wall construction, hanging bracket or table top.

This detail is of great value at the project level. Wall hanging or embedded installation requires evaluation of wall bearing, mounting bracket and horizontal calibration. Once the point position is determined, it is difficult to move again. Ground placement turns deployment into "positioning"-multiple devices can be placed in parallel, and moving points do not need to be re-constructed when moving lines are adjusted later. This flexibility translates directly into savings in deployment cycles and renovation costs for scenarios such as commercial complexes and pavilions that frequently adjust their spatial layouts.

04Micro-oblique touch surfaces: ergonomic restraint

The inquiry machine is a device for "standing up. The touch panel of L-type horizontal inquiry machine adoptsMicro-sloped design rather than fully horizontal: The wrist naturally droops during standing operation, and it is not easy to fatigue after long-term inquiry. The panel with inclination angle can also reduce the interference of dust accumulation and light reflection at the top, and also reduce the probability of false touch.

With G G capacitive touch scheme (20-point touch, accuracy ≤ 2mm, no drive), fingers or stylus can be operated accurately. Here is a data that is often ignored:Touch life 60 million times. According to the estimation of 5000 hits per day at high passenger flow points, 60 million hits ÷ 5000 hits/day ÷ 365 days ≈ 33 years-far exceeding the normal service cycle of a piece of equipment. This means that during the life cycle of the device, the touch module hardly needs to be replaced, and the touch cost is "one-time.

05Heat dissipation and power consumption: economic account of 7 × 24 operation

The inquiry terminals in the government affairs hall and hospital outpatient service are 7 × 24 standby and operate at full capacity during the day. The design of heat dissipation and power consumption directly determines whether the equipment can be stably carried, and also determines the power consumption cost of the project.

L-type horizontal inquiry machineStandby power consumption ≤ 1W, rated power consumption ≤ 95WThe working temperature range is 0-55 ℃, suitable for indoor operation throughout the year. According to the full load estimation of rated power consumption, the annual power consumption of a single unit is about 832kWh(95W × 24h × 365d); The actual query scenarios are mostly intermittent loads, and the real power consumption is lower than this value. For a project that deploys dozens of devices, this figure is a deterministic cost that can be budgeted in advance, rather than an unexpected expense discovered after the fact.

The internal wiring structure also standardizes the cable layout to avoid cable accumulation affecting heat dissipation and maintenance-this is an "invisible" part of the structural design.

06Materials and finishes: Appearance is part of the life cycle

For equipment in public spaces, appearance life is as important as equipment life. L-type horizontal inquiry machine adoptsCold-rolled steel plate (metal spray) body and aluminum profile frameThe front of the touch panel is covered with tempered glass-metal spray provides strength and corrosion resistance, tempered glass is wear-resistant and easy to clean, and aluminum profile frame ensures smooth appearance and texture. Standard color to provide black, white, silver three, can also be customized according to the needs of the project color and silk screen LOGO.

For scenes such as shopping malls and exhibition halls that require spatial texture, whether the appearance of the equipment is in harmony with the environment often directly affects the perception of acceptance. The low maintenance characteristics of the matte metal surface also reduce the labor cost of daily cleaning.

07L-type and K-type: not a substitution relationship, but a scene division of labor.

In the horizontal inquiry machine family, the L-type and K-type are often compared together. The difference between the two is essentiallyDifferences in structural thinking: Type K adopts an integrated inclined plane structure, the inclined plane angle is controlled at about 45, and the sensitivity optimization of the edge area of the screen with the touch algorithm is matched to form a double-layer anti-miscontact mechanism of "structural algorithm"; The L-type separates the support from the operating surface, and uses the L-type bracket to carry the micro-inclined panel, with lower center of gravity, cleaner routing and no wall construction.

Therefore, the selection is not "which is better", but "which is more matching": for scenes with high-frequency standing queries and strong demand for anti-false touch, K-type inclined plane and algorithm filtering have more advantages; For scenes that attach importance to stable structure, neat routing and flexible deployment, L-type is a more appropriate choice. The two can also be deployed in combination in the same project-for example, the hospital outpatient hall uses the K machine to undertake high-frequency queries, and the L machine to undertake close-range queries beside the guidance desk.

09The 8 most common questions buyers ask before placing an order

10Conclusion: There is no standard answer to structural design, but there is a framework for judgment.

For the purchase decision of L-type horizontal inquiry machine, it is recommended to follow four steps:First clear the location scene and the flow of people characteristics, and then ask for specifications and quality control test records to do written verification, and then inspection factory or proofing actual measurement, and finally according to the batch and delivery cycle to determine the business plan.. Align the "parameter" with the "field" and the selection will not go wrong.
