Abstract
Description
Technical Field
[0001] This invention relates to HMI display modules, and more specifically, to movable pluggable interfaces and electronic devices suitable for human-computer interaction. Background Technology
[0002] HMI (Human Machine Interaction) is the interface between humans and computers, and between humans and the CPUs of various commercial and industrial controllers, for establishing communication and exchanging information. In commercial and industrial equipment, this interface is mainly manifested in various display modules (with or without touch support) and buttons.
[0003] Traditional HMI modules are designed as an integrated system, using internal wiring (ribbon cables, FPC, PCB, etc.) to assemble and fix them to the controller motherboard into a single product.
[0004] In actual product applications and usage scenarios, customer needs vary widely. For the same product, some customers require a built-in HMI module, while others do not. To meet the diverse needs of different scenarios and customers, manufacturers need to develop and design various product structures and even multiple control motherboards. Furthermore, if products have significantly different appearances, they essentially become two or more completely different products. This necessitates more development verification, reliability testing, stability testing, and various product certification tests before they can be launched and sold. This not only increases development difficulty and lengthens the development cycle but also increases development and testing workload, certification testing, and significantly increases development time and economic costs.
[0005] Patent document CN215734312U discloses a rail-mounted HMI integrated communication industrial-grade dual-network IoT configuration smart gateway, including a rail-mounted industrial control housing. The interior of the rail-mounted industrial control housing houses a display module, a data transmission module, and a data processing module. This rail-mounted HMI integrated communication industrial-grade dual-network IoT configuration smart gateway provides multi-directional data access, data output, and display. It ensures data accuracy through multiple communication methods while completing multiple data processing and management tasks. Based on a core gateway series, it uses its own communication interface to connect to various on-site equipment parameters and monitoring methods. Furthermore, relying on its own data transmission channel, it enables diversified data applications, effectively maintaining compatibility with existing environments while compensating for the shortcomings of existing product technology frameworks.
[0006] Patent document CN113626085A discloses an industrial HMI terminal based on the Allwinner A40i processor. This terminal comprises hardware and software components. The hardware component includes a main processor module and peripheral circuitry connected to the main processor module. The peripheral circuitry includes a power module, a storage module, a video module, an RS232 communication module, an RS485 module, a USB module, a LAN communication module, a touch function module, and a display module. The storage module includes DRAM, eMMC, and SD card. The power module includes a DC-DC converter module and a power management module. The terminal software component includes a root system, an RTOS system, and RTS software.
[0007] Patent document CN105761654A discloses a flexible and easily expandable LCD testing platform, comprising: a core control module (the core of the entire system, controlling various system functions, composed of a CPU, GPU, and DDR memory); an eMMC module (used to store application programs and image data); a display output interface (including two parts: an RGB / LVDS output interface module and a display interface expansion module); an LCD power supply module (an expansion module); external interface modules (including an Ethernet interface module, an SD card interface module, a USB interface module, and a serial port module); an external MCU module; and IO expansion and an HMI interface. The HMI interface module provides a human-machine interface, allowing users to configure and monitor the system independently of a PC.
[0008] However, the USB mentioned in the aforementioned patent documents is only one of the functional interfaces and is fundamentally different from the present invention.
[0009] Patent document CN209748800U discloses a TYPE-C connector connection structure. The TYPE-C connector has 24 pins on both sides of the slot, which are mirrored on both sides of the slot. Among the 24 pins, pins 2, 3, 8, 10, 11, 14, 15, 20, 22, and 23 are not included in the USB 2.0 definition. Specifically, pins 2, 3, 22, and 23 are connected to the audio output function of the tablet's main controller; pins 10, 11, 14, and 15 are connected to the audio return function of the main controller; pin 8 is connected to the power amplifier enable function of the main controller; and pin 20 is connected to the speaker insertion detection function of the main controller. This directly redefines the function of the tablet's TYPE-C connector. While maintaining the original support for USB 2.0 reversible insertion, it solves the connection problem between the tablet and the speaker by utilizing the unused pins of the USB 2.0 function. This avoids the drawbacks of using a docking station, such as increased cost, design difficulties, and damage to the product's appearance.

[0073] 1. This invention utilizes USB Type-C to enable compatibility between products from different manufacturers and brands through a unified physical interface and signal definition interface, making HMI modules a unified interface accessory product.
[0074] 2. For brand manufacturers, this invention can greatly reduce the time and economic costs of repeated product development, enabling compatibility between different products and models within the manufacturer.

[0079] Figure 1 Defines the SPI standard interface.
[0080] Figure 2 Defines the I2C standard interface.

[0084] Figure 6 This is the definition of the USB Type-C male connector for this invention. Detailed Implementation
[0085] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0086] In order to reduce the difficulty and cost of development and design, and to make it more flexible and convenient to meet the needs of various scenarios, HMI modules can be connected to industrial and commercial controller products through a standard interface to form actual product forms.
[0087] Its advantages are as follows: Firstly, for manufacturers, developing and designing standard HMI modules (mainly interface definition standards) only requires separate development and design of the HMI module (or separate updates and replacements). The main controller and the HMI module are two completely independent entities, interfacing through pre-designed and defined interfaces. The HMI module is compatible with and matches different main controller products, and can be certified independently or integrated with the main controller as a single product for certification and market release. For end users, the product offers the freedom to flexibly choose different configurations to meet their specific usage scenarios and needs, and future upgrades can be made as required, significantly reducing costs and providing great flexibility and convenience.
[0088] Therefore, developing a standard HMI module offers significant advantages. However, when choosing a standard interface for an HMI module, most industrial and commercial controller products are small embedded devices, unsuitable for common display interfaces such as HDMI, VGA, and DP. Furthermore, these interfaces only support unidirectional display output from the controller and cannot support control signal input, thus they cannot be used as standard interfaces for HMI modules. Among embedded standard interfaces, the currently mainstream USB Type-C is undoubtedly the best choice. This invention primarily utilizes USB Type-C to design a removable and pluggable interface for industrial and commercial controllers.
[0089] For designing standard interfaces, taking the HMI module interface as an example, regardless of the physical interface form, the standard interface design and definition mainly consists of two aspects: signal (including power) interface and physical interconnection interface.
[0090] Signal (including power) interface
[0091] Firstly, regardless of the product form, the functions of an HMI module are nothing more than display, touch input, and keyboard (including various function keys).
[0092] Therefore, these functional devices can be input and output in two ways:
[0093] Signal input / output method A: These functions are connected to the main controller CPU (or processor) via SPI+I2C to input and output signals, enabling human-machine interaction between humans and devices.
[0094] Signal input / output method B: The HMI module can be designed as a standard USB peripheral through USB 2.0. The controller (or dedicated USB peripheral interface chip) in the HMI module can realize USB display peripherals, touch screen and keyboard input peripherals.
[0095] Therefore, the maximum set of signals required for these HMI functional modules is SPI (4 lines) + I2C (2 lines) + USB (2 lines) + 2-3 reserved control signal lines.
[0096] Physical Interoperability Interface
[0097] For embedded small products and devices, the mainstream, universal, and most widely used interface is undoubtedly USB Type-C. The advantages of USB Type-C include: First, unlike the ordinary USB A interface, USB Type-C is smaller and occupies less space, making it more suitable for embedded device applications. Unlike mini USB, Micro USB, and Micro USB AB interfaces, it doesn't have directional characteristics requiring foolproof design. The interface only has 5 internal signal lines, and USB 3.0 only adds 2 pairs (5 signal lines in total) of differential input / output signal pairs. Therefore, existing interfaces cannot meet the signal line requirements described above. The standard USB Type-C interface has 12 contacts on each side of the substrate, totaling 24 contacts on both sides. This means that standard USB Type-C can support up to 24 signal line transmissions (including power and ground pins). After deducting 4 power lines and 4 GND (ground) pins, 16 signal lines remain available for allocation. Therefore, the signal pin margin of the USB Type-C interface fully meets the requirements. Meanwhile, the standard USB Type-C specification supports reversible insertion, eliminating concerns about interface orientation and the need for foolproof design, making it very convenient for users and reducing the risk of interface damage or burnout due to incorrect insertion. Therefore, using the USB Type-C interface as the ideal interface form for designing and defining the standard HMI module in this invention is the most ideal interface form.
[0098] The standard USB Type-C interface is defined as follows: Figure 3 , Figure 4 As shown, it consists of male and female connectors that match each other. The signal definitions of the two connectors are aligned as required (signal transmission and signal reception docking). After the male connector is inserted into the female connector, signal interconnection is achieved.
[0099] The following provides a more detailed explanation of how this invention utilizes USB Type-C for HMI module standard interface design.
[0100] The standard USB Type-C interface and signal definitions cannot be directly applied to HMI modules. As mentioned above, the required signals cannot be met. Therefore, the main innovation of this invention lies in using the standard USB Type-C physical interface to define and standardize the HMI module interface. The internal signal definitions of the USB Type-C interface are completely innovative. To avoid scenarios such as incorrect device insertion or users connecting the controller with other USB Type-C interface data cables, the signal definitions within the USB Type-C interface adopt the standard USB Type-C interface definitions that are fully compatible with USB 2.0, power, and ground. Other USB 3.0 and USB Type-C related signal interfaces are redefined for HMI module application.
