I. The Application Value of Industrial Touch Screens in Warehouse Logistics AGV Equipment
The core requirements of the warehouse logistics AGV equipment are to achieve “precise transfer, efficient scheduling, and convenient operation and maintenance”. The application of industrial touch screens is not simply the addition of an operation terminal, but rather through visual interaction and precise control features, it optimizes the operation and management logic of the AGV equipment. Its core application value lies in three aspects, which are in line with the actual operational needs of warehouse logistics:
Simplify operation procedures and enhance scheduling efficiency: The transfer tasks, path planning, start-stop control, etc. of AGV equipment can be accomplished through the visual interface of the industrial touch screen, replacing the traditional complex key operations or remote terminal control. Operators do not need professional programming skills and can quickly master the tasks’ assignment and path adjustment operations, reducing the operation steps and improving the scheduling efficiency of AGV equipment, meeting the high-frequency transfer requirements of warehouse logistics.

2. Achieve visualized status display and ensure precise transfer: The industrial touch screen provides real-time display of the operation status of the AGV equipment, including current location, transfer task progress, battery status, driving speed, load condition, and other core information. Operators can directly grasp the operation dynamics of each AGV and promptly identify transfer deviations, path congestion and other issues, ensuring precise and efficient material transfer and avoiding material misdelivery or omission.
3. Optimize operation and maintenance experience, reduce downtime losses: During the operation of AGV equipment, problems such as path deviation, insufficient power, and mechanical failures may occur. The industrial touch screen can receive fault signals from the equipment in real time and display clear fault prompts (such as fault codes, fault locations, and handling suggestions) on the interface. Operators can quickly identify and resolve faults based on the prompts and complete the equipment reset, thereby shortening the downtime of the AGV equipment and reducing losses caused by interruptions in warehouse logistics and transportation.
   Compared with ordinary civilian touch screens, the industrial touch screens applied in AGV equipment for warehouse logistics need to be adapted to the working conditions such as dust, humidity, vibration, and electromagnetic interference in the warehouse. They should also possess features such as high touch accuracy, anti-interference, low power consumption, and easy installation, to ensure stable performance during long-term and high-frequency operation, and to meet the mobility and collaborative operation requirements of AGV equipment.
   II. Core Application Scenarios of Industrial Touch Screens in Warehouse Logistics AGV Equipment
   The application of AGV equipment in warehousing logistics covers the entire process of warehouse entry, storage, picking, and outbound. The application scenarios of industrial touch screens are deeply integrated with the transfer process and operation requirements of AGV equipment. Combined with the types of AGV equipment (such as concealed AGV, traction AGV, and stacker AGV), it can be specifically divided into four core scenarios, covering the entire process of operation, monitoring, and operation maintenance:
   (1) Task Scheduling and Path Setting Scenario
   Task scheduling is the core function of AGV equipment. The industrial touch screen, as the core terminal for task dispatching and path setting, is mainly applied in the following aspects:
   Task dispatching and management: Operators input the information of the transfer tasks through the industrial touch screen, including the name of the materials, specifications, starting location, target location, transfer priority, etc. The system automatically associates the idle status of the AGV equipment and allocates the tasks to the appropriate AGV devices. The interface supports operations such as task viewing, modification, cancellation, and suspension. Operators can monitor the progress of task execution in real time and adjust the task priority according to the requirements of warehousing and logistics to ensure the orderly progress of the transfer tasks.
4. Path Planning and Adjustment: For different transfer scenarios, operators can set the travel path of the AGV equipment through the industrial touch screen, supporting two modes: manual path planning and automatic path optimization. In the manual mode, the travel path can be drawn on the touch interface, precisely specifying the route of the AGV; in the automatic mode, the system will automatically optimize the travel path based on the warehouse layout, material location, and congestion situation of the path. Operators can view the optimized path on the touch screen and make manual adjustments when necessary to ensure the efficient and safe operation of the AGV equipment.
5. Multi-AGV Collaborative Scheduling: In large warehouses, when multiple AGV devices are operating simultaneously, operators can use the industrial touch screen to achieve collaborative scheduling. They can view the operating status and task allocation of all AGV devices, avoiding conflicts in AGV paths and overlapping tasks, ensuring the efficient operation of multiple AGVs and improving the overall transfer efficiency of the warehouse.
   (2) Real-time Monitoring Scenario of Operating Status
   The stable operation of AGV equipment is the guarantee for the storage, logistics and transportation. The industrial touch screen, as the status monitoring terminal, presents the core data of the equipment operation in real time. The applications include:
   Core parameter monitoring: The industrial touch screen displays real-time information about the AGV equipment’s speed, load weight, remaining battery power, and mileage. Operators can directly understand the operating status of the equipment. When the parameters exceed the reasonable range (such as low battery power or excessive load), the interface automatically gives a prompt to remind the operator to handle it promptly to prevent equipment failure.
6. Position and Path Monitoring: Through the graphical display on the touch interface, the specific position and travel path of the AGV in the warehouse are presented in real time. Operators can precisely track the transfer progress of the AGV. When the AGV encounters path deviations, jams, or other issues, they can remotely issue adjustment instructions via the touch screen to guide the AGV back to the correct path, ensuring precise transfer.
7. Surrounding environment monitoring linkage: Some AGV devices are equipped with components such as cameras and sensors. The industrial touch screen can display real-time images of the surrounding environment of the AGV. When abnormal situations such as obstacles or personnel are detected, the interface automatically issues an alarm prompt. At the same time, the AGV device automatically stops operating. The operator can view the on-site situation through the touch screen and issue instructions such as avoidance and detour to ensure the safety of the AGV device and personnel.
   (III) Fault Diagnosis and Emergency Response Scenarios
   In the warehouse and logistics scenarios, the failure of AGV equipment will directly affect the transfer efficiency. The industrial touch screen, as the core terminal for fault diagnosis and emergency handling, is mainly applied in the following aspects:
   Real-time fault warning and notification: During the operation of the AGV equipment, the fault data collected by the sensors is transmitted in real time to the industrial touch screen. When the equipment encounters a fault (such as failure in path recognition, motor failure, abnormal power supply, mechanical jamming, etc.), the touch screen automatically pops up an alarm prompt, including the fault code, fault location, fault description and handling suggestions. Operators can quickly identify the cause of the fault based on the prompt and shorten the troubleshooting time.
8. Fault Handling and Equipment Reset: For common faults (such as low battery power, minor path deviation), operators can directly issue handling instructions via the industrial touch screen, such as activating the backup power supply, adjusting the path, restarting the equipment, etc. For complex faults, fault information can be recorded on the touch screen, and the fault data can be exported to provide reference for maintenance personnel. After the repair is completed, the equipment can be reset through the touch screen to restore normal operation.
9. Emergency operation control: In case of an emergency situation (such as collision, jamming, or material drop) with the AGV equipment, the operator can quickly stop the equipment operation by pressing the emergency stop button on the industrial touch screen. This prevents the expansion of the fault; at the same time, instructions for emergency avoidance and material clearance can be issued through the touch screen to ensure on-site safety and minimize losses.
   (4) Equipment Operation and Maintenance and Parameter Calibration Scenarios
   The regular maintenance of AGV equipment is the foundation for ensuring its long-term stable operation. The industrial touch screen, as the maintenance terminal, is mainly applied in the following aspects:
   Maintenance plan management: Operators use the industrial touch screen to formulate maintenance plans for AGV equipment, including daily inspections, regular maintenance, component replacements, etc. They set maintenance times and contents, and the system automatically reminds the operators to perform maintenance operations. At the same time, they record the maintenance situation to form maintenance files, which support real-time query and are convenient for analyzing equipment operation patterns and optimizing maintenance plans.
10. Parameter Calibration and Debugging: The path recognition accuracy, traveling speed, load capacity, etc. of the AGV equipment can be calibrated and debugged through the industrial touch screen. Operators can adjust the relevant parameters according to the requirements of warehouse logistics to ensure the operational accuracy and adaptability of the AGV equipment. At the same time, the equipment can be debugged through the touch screen to test its various functions and ensure normal operation of the equipment.
11. Battery Management and Charging Control: The industrial touch screen displays the battery status of the AGV equipment in real time. When the battery level drops below the preset threshold, an automatic charging prompt is issued. The operator can issue the charging instruction through the touch screen to guide the AGV equipment to automatically go to the charging area for charging. At the same time, charging parameters can be set to monitor the charging progress and avoid overcharging or insufficient charging, thereby extending the battery life of the equipment.
    III. Key Points for Adaptation Design of Industrial Touch Screens in AGV Equipment
    In the warehouse logistics scenario, AGV equipment needs to move and operate within the warehouse, facing complex conditions such as dust, humidity, vibration, and electromagnetic interference. Moreover, it has high requirements for operational convenience, running stability, and energy consumption control. The adaptation design of industrial touch screens needs to be optimized specifically, with particular attention to the following four aspects:
    (1) Environmental Adaptability Adaptation Design
    The warehouse and logistics facilities are subject to various conditions such as dust, humidity, and mechanical vibration. Some of the warehouses also have high and low temperature environments. Industrial touch screens need to have excellent environmental adaptability to ensure long-term stable operation:
    Protection level compatibility: Select industrial touch screens with a protection level of IP65 or above, which have excellent dust-proof and water-proof capabilities. This prevents dust and moisture from entering the internal components of the touch screen, avoiding touch malfunction and circuit short-circuiting. The surface of the screen is coated with anti-fouling and anti-abrasion layers, which facilitate cleaning and enhance wear resistance, meeting the high-frequency operation requirements of warehouse logistics.
12. Anti-vibration and anti-shock design: During the movement and operation of AGV equipment, vibrations will be generated. The industrial touch screen needs to adopt a vibration-resistant hardware structure to ensure that the touch screen is firmly installed and the touch operation is stable, without any loosening or touch offset issues; the screen panel is made of high-hardness tempered glass, which can withstand minor collisions and dust impacts, and prevent the panel from being damaged.
13. Adaptation to wide temperature and low power consumption: For scenarios in high and low temperature warehouses, a wide-temperature industrial touch screen is selected, with a working temperature range covering -20℃ to 60℃. This avoids screen aging due to high temperatures and startup abnormalities caused by low temperatures. At the same time, a low-power touch screen and driver components are chosen to reduce energy consumption. Combined with the battery power supply of the AGV equipment, it extends the equipment’s battery life and meets the long-term transportation requirements in the warehouse.
    (2) Touch Control Performance Adaptation Design
    The operation of AGV equipment is mostly carried out in motion or on-site quickly. Industrial touch screens need to have high touch accuracy and sensitivity, be suitable for convenient operation requirements, and the touch performance should meet the key requirements. These include:
14. Compatibility of touch control accuracy and sensitivity: Select an industrial touch screen with high touch control accuracy. The touch control accuracy error is controlled within ±0.5mm, ensuring that operators can precisely issue task instructions and adjust parameters; support for glove operation (operators usually wear protective gloves during warehouse operations), enabling precise touch control without applying excessive pressure, thus avoiding operational fatigue; optimize the touch response speed, with the response time controlled within 30ms, ensuring that operation instructions take effect in real time without any delay.
15. Touch control error prevention and anti-misoperation design: Implement touch control error prevention functions to prevent operators from making incorrect instructions due to accidental touches in moving operations or noisy environments. For example, for critical operations (such as emergency stop, task cancellation), a secondary confirmation interface needs to be set up; for accidental operations, the interface can be used to quickly cancel the operation, reducing the impact of operational errors.
16. Multi-touch Compatibility: Supports multi-touch functionality. Operators can quickly switch interfaces and adjust paths through gestures (such as zooming, sliding), enhancing operational convenience and meeting the requirements for rapid scheduling of AGV equipment.
    (III) Interface Design Adaptation Design
    The interface design of industrial touch screens should be in line with the operation habits of AGV equipment and the requirements of warehouse logistics scenarios. It should be simple, intuitive, and highlight key points, facilitating operators to quickly get started and operate efficiently. The key points of interface design adaptation include:
17. Layout Rationality: The interface layout should be clear and orderly. Common functions (such as task dispatching, status monitoring, emergency stop) should be placed in prominent positions to reduce the operation steps for operators. Divide the interface according to functional modules (such as task management, status monitoring, fault troubleshooting, operation management), with a clear logic, facilitating operators to quickly switch functions and meeting the high-speed operation requirements of warehousing and logistics.
18. Visual Presentation: The operation status, task progress, and fault information of AGV equipment are presented in a graphical and digital format. For instance, the position and travel trajectory of the AGV are shown in a map form, the equipment status (normal, faulty, charging, idle) is represented by icons in an intuitive way, and parameters such as battery level and speed are clearly displayed in numbers, facilitating the quick understanding and judgment by operators. The text and icons should be clear and prominent to avoid difficulties in recognition due to reflection or blurriness.
19. Ease of Operation: The interface operation process should be simple, supporting the invocation of task templates and the saving of common paths to reduce repetitive operations; setting shortcut keys to facilitate the quick switching of common functions by the operators; the interface supports custom layout, allowing operators to adjust the positions of function modules according to their own operating habits; for mobile operation scenarios, optimizing the font size of the interface and the size of touch buttons to enhance the ease of operation.
    (4) Compatibility and Reliability Adaptation Design
    Industrial touch screens need to be compatible with the control system, sensors, actuators and other components of the AGV equipment. They must also have high reliability to ensure long-term continuous operation. Key points for adaptation include:
    Compatibility Adaptation: The industrial touch screen needs to be compatible with the control system of the AGV equipment (such as PLC, main control chip), supporting various industrial communication interfaces (such as RS-485, Ethernet, USB, Wi-Fi), enabling bidirectional data transmission, ensuring real-time synchronization of task instructions, operation status, etc.; at the same time, it needs to be adapted to the operating system of the AGV equipment to ensure stable driver operation without compatibility issues, and support connection with the warehouse management system (WMS) and warehouse execution system (WES), achieving data collaboration.
20. Reliability Adaptation: Utilize industrial-grade core components to ensure the long-term stability of the touch screen. The service life can reach over 5 years and it can withstand long-term high-frequency operation. It has a self-diagnosis function for faults. When the touch screen experiences its own faults (such as touch malfunction or display abnormalities), it will automatically issue an alarm prompt, facilitating the operators to handle the issue promptly. A data backup function is also set up to ensure that task information, fault records, maintenance files, etc. are not lost, avoiding data loss-induced interruption in transportation.
