The four core application scenarios of industrial panels in self-service coffee machines
（1） C-end user interaction interface (the most basic application)
Targeting consumers for ordering, paying, and picking up meals, with mainstream sizes of 7 inches (small desktop)/10.1 inches (commercial mainstream)/15.6 inches (high-end cabinet), using PCAP capacitive multi touch industrial screen:
1. Beverage visualization selection
Display customized menus for American style, latte, cappuccino, hot and cold drinks, sweetness/ice content, high-definition IPS wide viewing angle, clear viewing from multiple angles; Indoor brightness of 400~500cd/㎡, outdoor models by the window are equipped with 800~1000cd/㎡ high brightness anti glare industrial screens, which do not reflect strong light and make it difficult to see the interface clearly.
2. Omnichannel payment interaction
Screen integrated scanning box, supporting card swiping and membership code verification; Payment countdown and real-time pop-up window for order status.
3. Order Process Guidelines
Countdown for cup dispensing, shortage of beans/water/milk reminders, cleaning tips, and fault pop ups; Support graphic and simple animation guidance operation, reducing the threshold for middle-aged and elderly users.
4. Advertising value-added operation
Split screen design: The upper half displays beverage advertisements and promotional coupons in a rotating manner, while the lower half features interactive ordering. The industrial panel supports 7 × 24-hour video decoding without the need for additional advertising hardware.
（2） Bottom layer intelligent control of equipment (core value of all-in-one solution)
The integrated industrial touch panel comes with an embedded industrial control motherboard (Android/Linux), serving as the "brain" of the coffee machine, coordinating all mechanical modules, and replacing traditional single-chip microcontrollers for simple control:
1. Precise control of extraction parameters
Real time collection of sensor data on water temperature, water pressure, grinding thickness, and liquid extraction time, preset/adjust the formula through the panel interface, and stabilize the coffee taste; Can store over 30 custom beverage recipes, one click access.
2. Automatic cleaning program control
Built in cleaning system on the panel: automatic on/off flushing, descaling of milk ducts, and drainage of wastewater; Operators can initiate deep cleaning with one click on the screen and record cleaning logs.
3. Real time monitoring of material inventory
Connect the weight sensors of the bean bin, water tank, and milk powder box, and display the remaining raw materials in real-time on the panel; Automatically push replenishment reminders to the backend below the threshold to avoid empty material cards.
4. Fault self check and local alarm
Heating faults, abnormal water pumps, stuck cups, doors not closed and other issues will immediately pop up with error messages, and the fault codes will be recorded locally for easy on-site maintenance and repair.
（3） Operation backend management and remote operation and maintenance (essential for unmanned commercial core)
Industrial panels come standard with 4G, WiFi, and Ethernet communication, connecting to a cloud management platform to achieve multi device cluster control
1. Local backend operations (operations and maintenance personnel)
Permission grading interface: ordinary store clerks can view sales volume and export receipts; Administrators modify beverage prices, add or remove formulas, set advertisements, and adjust device temperature control parameters.
2. Remote cloud synchronization of data
Automatically upload sales volume, average order value, and hot selling beverage statistics for each order; The operator can remotely batch modify all coffee machine menus and update advertising materials.
3. Remote diagnosis and debugging
No need to visit, remotely view device operation logs, restart the system, and fix software bugs through the industrial panel remote desktop, significantly reducing offline operation and maintenance costs.
4. Equipment asset management
Record startup time, consumables consumption, and failure frequency, generate monthly operation and maintenance reports, and assist in optimizing deployment locations.
（4） Integrated structure and hardware matching application of the whole machine
1. Embedded standard installation
The industrial panel adopts an open frame/embedded aluminum profile shell, with a snap fit embedded in the coffee machine sheet metal cabinet. The ultra-thin body saves internal space of the equipment and is suitable for various compact cabinet, vertical, and desktop models.
2. Integration of multiple peripheral interfaces
Rich industrial I/O: serial port docking temperature control, motor; USB connected to barcode scanner and printer; Online transmission of data; GPIO docking devices include door locks, indicator lights, and cup dropping mechanisms.
3. Integrated protective structure
Front panel die cast aluminum seal+silicone waterproof rubber strip, with an overall IP65 rating; The screen surface is coated with AG anti fingerprint coating, which can clean coffee stains and water stains with a wipe, and has no scratches after long-term use.
