1. Overview of Industrial LCD Screens and Industrial Internet of Things

1.1 Technical Characteristics of Industrial LCD Screens

Industrial LCD screens are display devices designed specifically for industrial scenarios, with a variety of technical features to adapt to complex industrial environments. Their high durability enables stable operation under extreme conditions such as vibration, impact, high temperature, and low temperature. For example, touch screens with tempered glass or explosion-proof film design can maintain stability in harsh environments. Industrial LCD screens also support wide temperature operation, with some products able to work normally in the temperature range of -20℃ to 70℃, making them suitable for environments such as high-temperature workshops or low-temperature warehouses. In addition, the dustproof and waterproof rating of industrial LCD screens is usually IP65 or higher, capable of withstanding the invasion of dust, oil stains, and water stains. Their anti-interference performance is also excellent, ensuring accurate signal transmission and operational stability in industrial environments with strong electromagnetic interference. These technical features make industrial LCD screens an ideal display solution for industrial automation, intelligent manufacturing, transportation, medical equipment, and other fields.

1.2 Concept and Architecture of Industrial Internet of Things

The Industrial Internet of Things (IIoT) is the application of the Internet of Things in the industrial field. By connecting industrial equipment, sensors, control systems, etc., to the Internet, data acquisition, transmission, analysis, and application are realized, thereby optimizing the production process and improving production efficiency and quality. Its architecture is usually divided into four layers: the perception layer, the network layer, the platform layer, and the application layer. The perception layer consists of various sensors, RFID tags, etc., responsible for data acquisition in industrial sites; the network layer transmits data from the perception layer to the platform layer through wired or wireless networks; the platform layer stores, manages, and analyzes data, providing services such as data mining and machine learning; the application layer develops various applications according to industrial needs, such as production monitoring, equipment management, quality inspection, etc. The typical characteristics of the Industrial Internet of Things include intelligent perception, ubiquitous connectivity, digital modeling, real-time analysis, precise control, and iterative optimization, enabling the realization of intelligent and automated industrial production.

2. Design of Intelligent Integration Scheme

2.1 Data Acquisition and Transmission Scheme

Data acquisition and transmission are the foundation of the intelligent integration of industrial LCD screens and the Industrial Internet of Things (IIoT), and the rationality of their design directly affects the performance and efficiency of the entire system.

Data Acquisition Scheme

In the Industrial Internet of Things environment, data acquisition mainly relies on various sensors. These sensors can monitor key parameters in the industrial production process in real time, such as temperature, pressure, vibration, flow, etc. For example, in an automotive manufacturing workshop, by installing high-precision temperature sensors and vibration sensors on production equipment, the operating status data of the equipment can be collected in real time. The temperature sensor has a precision of ±0.1℃, and the vibration sensor has a frequency response range of 0 – 1000 Hz, capable of accurately capturing the subtle changes of the equipment. This data is preliminarily processed by a data collector and then transmitted to the industrial LCD screen for display.

The frequency of data acquisition is also an important design parameter. For real-time monitoring of key equipment, the data acquisition frequency is usually set to several times per second or even higher. For example, in the monitoring system of a high-precision CNC machine tool, the vibration data acquisition frequency can reach 100 times per second to ensure the timely discovery of abnormal vibration conditions of the equipment. For some non-critical parameters, such as ambient temperature, the acquisition frequency can be reduced to once per minute to reduce data transmission volume and system load.

Data Transmission Scheme

The reliability of data transmission is the key to ensuring the stable operation of the system. In industrial environments, due to strong electromagnetic interference, data transmission needs to adopt reliable communication protocols and anti-interference measures.

Common data transmission methods include wired transmission and wireless transmission. Wired transmission usually adopts industrial Ethernet or RS-485 bus. Industrial Ethernet has the characteristics of high bandwidth and low latency, meeting the needs of large-scale data transmission. For example, in the automated production line of a large factory, sensor data from various equipment is transmitted to the central control room through industrial Ethernet, with a data transmission rate of up to 100 Mbps and a latency of less than 1 ms. The RS-485 bus is suitable for long-distance, low-rate data transmission, with a transmission distance of up to 1200 meters, capable of connecting multiple devices to form a distributed control system.

Wireless transmission adopts technologies such as Wi-Fi, ZigBee, or LoRa. Wi-Fi technology is suitable for short-distance, high-rate data transmission, but its anti-interference ability is relatively weak. ZigBee technology has the characteristics of low power consumption, low rate, and high reliability, suitable for data transmission in sensor networks. LoRa technology has the advantages of long-distance transmission, low power consumption, and high capacity, suitable for large-scale Industrial Internet of Things scenarios. For example, in an intelligent warehousing system, sensor data distributed in various parts of the warehouse is transmitted to the central server through LoRa technology, with a transmission distance of up to 2 kilometers, low device power consumption, and a battery life of several years.

Optimization of Data Acquisition and Transmission

To improve the efficiency of data acquisition and transmission, edge computing technology can be adopted. Edge computing transfers the functions of data processing and analysis from the cloud or central server to edge devices near the data source, thereby reducing data transmission volume and latency. For example, in an industrial automated production line, by deploying an edge computing module on the data collector, the collected data is analyzed and filtered in real time, and only valuable data is transmitted to the cloud or central server for further processing. This not only improves the system’s response speed but also reduces network bandwidth demand and server load.

In addition, data compression technology can also be used to optimize data transmission. By compressing the collected data, the data transmission volume can be reduced, and the transmission efficiency can be improved. For example, using data compression algorithms such as Huffman coding or LZW coding can compress the data to 50%-70% of the original size, thereby significantly reducing the data transmission volume without reducing data quality.

2.2 Display and Interaction Design

Display and interaction design is an important part of the intelligent integration of industrial LCD screens and the Industrial Internet of Things (IIoT), aiming to provide users with an intuitive and convenient operation interface to improve the system’s usability and work efficiency.

Display Design

The display design of industrial LCD screens needs to consider a variety of factors to meet the special needs of industrial environments.

First, the screen resolution and size are important parameters. High-resolution screens can display more information and improve the clarity of the display effect. For example, a 21.5-inch industrial LCD screen with a resolution of 1920×1080 can clearly display complex production process diagrams, equipment status data, and real-time monitoring images.

In addition, the brightness and contrast of the screen also affect the display effect. In strong light environments, the screen brightness should reach above 500 cd/m² to ensure that users can clearly see the screen content. The contrast should reach above 1000:1 to improve the sense of hierarchy and detail of the image.

Secondly, the color performance of the screen is also a key to display design. Industrial LCD screens usually adopt wide color gamut technology, which can accurately reproduce various colors and meet the needs of different application scenarios. For example, in medical equipment, the screen needs to accurately display patients’ physiological data and medical images, and wide color gamut technology can ensure the accuracy of image colors.

In addition, the viewing angle of the screen also affects the user’s viewing experience. The viewing angle of industrial LCD screens should reach above 170° to ensure that users can clearly see the screen content from different angles.

Interaction Design

The goal of interaction design is to provide users with convenient and efficient operation methods.

Industrial LCD screens usually adopt touch screen technology, supporting multiple input methods such as fingers and styluses. Resistive touch screens have a lower cost and can support multiple input methods, but their durability is relatively poor. Capacitive touch screens have the advantages of high sensitivity, high transmittance, and good durability, suitable for industrial scenarios with high requirements for touch precision. For example, in the control panel of an automated production line, using a capacitive touch screen can achieve precise operations and improve production efficiency.

In addition to touch screen technology, interaction methods such as voice recognition and gesture control can also be adopted. Voice recognition technology can achieve the recognition and execution of voice commands, improving the convenience of operation. For example, in a noisy industrial environment, users can issue voice commands to control the operating status of the equipment through voice recognition technology.

Gesture control technology can achieve operations by recognizing the user’s gesture actions, improving the interactivity of the system. For example, in an intelligent warehousing system, users can query inventory information or schedule logistics equipment through simple gesture actions using gesture control technology.

Optimization of Display and Interaction

To improve the system’s usability and work efficiency, intelligent display and interaction technologies can be adopted. For example, through machine learning algorithms, the system can automatically adjust the display content and interaction methods according to the user’s operation habits and preferences.

In a production monitoring system, the system can automatically highlight the status information of key equipment according to the user’s focus and provide personalized operation suggestions.

In addition, augmented reality (AR) technology can be used to superimpose virtual information onto real scenes, providing users with more intuitive operation guidance. For example, during equipment maintenance, users can see the virtual model of the equipment and maintenance steps on the screen through AR technology, improving maintenance efficiency and accuracy.

3. Implementation and Optimization of Integration Scheme

3.1 Hardware Selection and Deployment

Hardware selection and deployment are key steps to achieve the intelligent integration of industrial LCD screens and the Industrial Internet of Things (IIoT). Rational hardware selection and deployment can ensure the stable operation and efficient performance of the system.

Hardware Selection

In terms of hardware selection, it is necessary to comprehensively consider the special needs of the industrial environment and the functional requirements of the system. For industrial LCD screens, products with high durability, wide temperature operation, dustproof and waterproof, and strong anti-interference capabilities should be selected. For example, a large factory selected industrial LCD screens with a protection level of IP65 and a working temperature range of -20℃ to 70℃ for its automated production line to adapt to the high temperature and dusty environment in the workshop.

In terms of screen size and resolution, appropriate models should be selected according to the actual application scenarios. For monitoring systems that need to display complex data and images, a 24-inch high-definition industrial LCD screen with a resolution of 1920×1200 can be selected.

For data acquisition equipment such as sensors, selection should be made according to the type and precision requirements of the monitored parameters. For example, in an industrial automated production line, high-precision temperature sensors (precision ±0.1℃) and vibration sensors (frequency response range 0 – 1000 Hz) are selected to collect the operating status data of the equipment in real time. At the same time, the communication interface of the sensor should also be compatible with the system, such as using sensors that support the Modbus protocol, which is convenient for communication with the data collector and industrial LCD screen.

In terms of network equipment, appropriate wired or wireless network equipment should be selected according to the data transmission requirements. For wired transmission, an industrial Ethernet switch can be selected, with a transmission rate of up to 1000 Mbps and a latency of less than 1 ms, meeting the needs of large-scale data transmission. For wireless transmission, a LoRa gateway can be selected, with a transmission distance of up to 2 kilometers, suitable for large-scale Industrial Internet of Things scenarios.

Hardware Deployment

Hardware deployment needs to be reasonably planned according to the layout of the factory and the production process.

Industrial LCD screens should be installed in positions that are easy for operators to observe and operate, such as the control room or equipment operation platform. At the same time, the installation angle and height of the screen should be suitable for the operator’s line of sight, avoiding reflection and obstruction. For example, in the automated production line of a certain factory, the industrial LCD screen is installed directly in front of the equipment operation platform, at a height level with the operator’s line of sight, facilitating real-time monitoring of the equipment status.

The deployment of sensors should be reasonably arranged according to the location and range of the monitored objects. For example, in an automotive manufacturing workshop, temperature sensors are installed in key parts of the production equipment, such as motors and oil tanks, to monitor the temperature changes of the equipment in real time. Vibration sensors are installed in positions such as the bearings and drive shafts of the equipment to monitor the vibration of the equipment. The installation of sensors should ensure their stability, avoiding loosening or damage to the sensors due to equipment vibration or impact.

The deployment of network equipment should be planned according to the path and range of data transmission. For wired networks, reasonable wiring should be carried out to ensure the neatness and safety of the lines. In large factories, an industrial Ethernet ring topology can be used to transmit sensor data from various equipment to the central control room.

For wireless networks, wireless base stations should be reasonably arranged according to the signal coverage range and equipment distribution. For example, in an intelligent warehousing system, multiple LoRa base stations are installed according to the layout of the warehouse and the distribution of sensors to ensure signal coverage of the entire warehouse area.

3.2 Software Development and Debugging

Software development and debugging are the core links to achieve the intelligent integration of industrial LCD screens and the Industrial Internet of Things (IIoT). By developing efficient software systems, data acquisition, processing, display, and interaction can be realized, enhancing the system’s intelligence level.

Software Development

Software development mainly includes the development of data acquisition modules, data processing modules, display modules, and interaction modules. The data acquisition module is responsible for collecting data from sensors and transmitting it to the data processing module. The data processing module analyzes and processes the collected data to extract valuable information. The display module presents the processed data in an intuitive way on the industrial LCD screen, such as charts and images. The interaction module realizes the interaction functions between the user and the system, such as touch screen operations and voice command recognition.

In the development process, a modular design method should be adopted, dividing the system into multiple independent modules for easy development and maintenance. For example, the data acquisition module can be developed using the Python programming language, utilizing its rich library functions to achieve data acquisition and communication of sensors. The data processing module can be developed using the C++ programming language, utilizing its efficient algorithms to achieve data analysis and processing. The display module and interaction module can be developed using the Qt framework, utilizing its powerful graphical interface functions to achieve data display and interaction.

At the same time, the reliability and stability of the software should be emphasized. In the development process, strict code testing and optimization should be carried out to ensure the stable operation of the software in the industrial environment. For example, through unit testing, integration testing, and system testing, the functions of each module of the software are tested to ensure their correctness and stability. In addition, stress testing and reliability testing should also be carried out to simulate various situations in the industrial environment and ensure the stability of the software under long-term operation and high load.

Software Debugging

Software debugging is an important link to ensure the normal operation of the system. In the debugging process, adjustments and optimizations should be made according to the actual operating conditions.

First, the data acquisition module should be debugged to ensure that sensor data can be accurately collected and transmitted to the data processing module. For example, by adding a log recording function in the data acquisition module, the status and content of data acquisition can be monitored in real time, and problems in data acquisition can be discovered and solved in a timely manner.

Secondly, the data processing module should be debugged to ensure the accuracy and efficiency of the data processing algorithm. For example, by comparing the data before and after processing, the effectiveness of the data processing algorithm is verified. At the same time, the data processing algorithm should be optimized to improve its operating efficiency and reduce system latency.

Finally, the display module and interaction module should be debugged to ensure the user-friendliness of the interface and the convenience of interaction. For example, by actually operating the industrial LCD screen, the clarity and accuracy of the display content and the sensitivity and timeliness of the interaction functions are checked. According to user feedback and actual usage, the display interface and interaction methods are optimized to improve the user experience of the system.
