An agricultural harvester is an integrated machine for harvesting crops. It is capable of completing the harvest quickly and concentrating the grain into storage silos, which are then conveyed to transport trucks via conveyor belts. Alternatively, harvesting can be done manually by laying the crop stalks in the field and then picking and threshing them with grain harvesting machinery. Agricultural harvesters include various types such as side-mounted, backpack, hand-held, horizontal and vertical, etc. These different types of harvesters are suitable for different farming environments and crop types.
The benefits of touch screen replacing traditional agricultural buttons as the interaction interface:
1. Convenient operation: touch screen adopts touch operation mode, users only need to click, drag and other operations on the screen through the finger or stylus to achieve the control of the equipment, without the use of physical buttons or knobs, the operation is more intuitive and convenient.
2. Rich display information: the monitor can display text, images, video and other information, the user can intuitively understand the harvester's working status, parameter settings, troubleshooting and other information through the touch screen, improving the visualisation of the equipment and the degree of information.
3. Improvement of safety: touch screen control can avoid misoperation or malfunction caused by mechanical wear and tear, poor contact and other problems of physical buttons, and it can also reduce safety accidents caused by improper operation.
4. Strong scalability: The software and hardware of the touch screen control system are modular, which can be customised and expanded according to actual needs, facilitating secondary development and upgrading by users.
5. Convenient maintenance: through the touch screen, you can real-time monitoring of the operating status of the equipment and fault information, convenient for maintenance personnel to carry out troubleshooting and repair. At the same time, the operation records and logs of the touch screen are also convenient for maintenance personnel to track and manage the use of equipment.
Touch screen applications in agricultural harvesters face challenges:
1. Environmental adaptability: Agricultural harvesters usually work outdoors and face harsh environments such as dust, water spray, and direct sunlight, which challenges the durability and clarity of the touch screen.
2. Touch accuracy: In the vibrating and bumpy working environment of the harvester, the accuracy and responsiveness of the touch screen may be affected.
3. Cost issues: High quality touch screen technology is costly and may increase the manufacturing cost of the harvester.
Solution:
1. Use high-quality, durable touchscreen materials: Choose durable, scratch- and smudge-resistant touchscreen surface materials, such as reinforced glass or anti-scratch coatings, to prolong the service life of the touchscreen.
2. Optimise touchscreen and display hardware and software: Ensure that touchscreen and display hardware and software are optimised to reduce latency and improve responsiveness and accuracy. Also, optimise the brightness and contrast of the display to ensure a clear display even under strong outdoor light.
3. Adoption of anti-interference technology: Use anti-interference technology such as electromagnetic shielding and filters to reduce the impact of external electromagnetic interference on the touch screen.
4. Accurate calibration and correction technology: For large-size touch screen, it is necessary to ensure that the touch sensor responds uniformly across the entire screen surface. Precise calibration and alignment techniques can help solve this problem.
5. Cost Balance: Finding the balance between cost and performance, and choosing an affordable touchscreen solution for a specific need. At the same time, reduce the cost of touchscreens through scaled production and technological advances.
