In open-air operation scenarios such as photovoltaic power plants, smart water conservancy and outdoor security, industrial panel PC have long become the core carrier for on-site data collection, equipment regulation and status visualization. However, for a long time, the vast majority of operation and maintenance personnel have been enduring a common yet hard-to-solve pain point: under the direct strong sunlight at noon, the monitoring screen turns whitish with blurry text. Even when leaning close to the screen, it is difficult to see real-time power generation data and equipment operating status clearly. This not only slows down the daily inspection efficiency, but even hides potential safety hazards for power plant operation due to failure to identify abnormal data in time.

According to industry survey data, among the distributed and centralized photovoltaic power plants in operation in China, over 90% of the operation and maintenance teams have encountered the problem of unclear screens under outdoor sunlight. To control costs, most traditional industrial panel PCs adopt ordinary indoor displays, without professional optical enhancement treatment or display optimization for outdoor strong light environments. Under direct strong sunlight at noon in summer, the screen reflectivity exceeds 60%, and the visible clarity is less than 30% of that indoors. Operation and maintenance personnel often have to set up sunshades or hold light shields to barely read data. Not only is the operation cumbersome, but the extra shading equipment also greatly increases the operation and maintenance burden, especially in complex photovoltaic power plant scenarios such as mountainous areas and deserts. More critically, many outdoor monitoring points of power plants do not have extra shading facilities. Repeatedly trying to identify screen content under strong light for a long time can easily cause visual fatigue, leading to frequent occurrences of misreading parameters and missing alarm information, which directly affects the operation and maintenance efficiency and power generation revenue of the power plant.

To completely solve this pain point that has plagued the industry for many years, we cannot only rely on palliative auxiliary measures such as installing sunshades later. We must start from the underlying hardware design of industrial panel PCs to create professional equipment optimized specifically for outdoor strong light scenarios. The industrial panel PC USR-SH800 is exactly the tailor-made solution for such scenarios.

As an all-in-one IoT screen designed for industrial-grade outdoor scenarios, USR-SH800 has undergone targeted enhancements from the screen hardware to the whole machine's environmental adaptability, fundamentally solving the problem of unclear visibility under sunlight. Its 10.1-inch high-definition touch capacitive screen adopts professional anti-glare glass and low-reflection surface treatment technology, which greatly reduces the screen reflectivity under direct sunlight. Even at the photovoltaic power plant site under direct strong sunlight at noon, it can clearly present key data such as power generation, module temperature and grid connection status. No extra shading facilities are needed, and operation and maintenance personnel can quickly read all information at a normal operating distance. Actual test data shows that in a 10,000lux strong light environment equivalent to outdoor noon sunlight, the visible clarity of USR-SH800's screen is more than 4 times higher than that of ordinary industrial screens, completely eliminating the problems of whitish screen and blurry text.

In addition to the core strong light display advantage, the overall performance of USR-SH800 fully meets the strict requirements of outdoor scenarios such as photovoltaic power plants. It is equipped with a domestic RK3568 quad-core 64-bit industrial-grade processor with a maximum main frequency of 2.0GHz, paired with 4GB DDR4 RAM and 32GB eMMC storage, and integrated with an NPU neural network processor with 1.0TOPS computing power. Even when accessing data from hundreds of photovoltaic inverters and environmental monitoring sensors at the same time, it can smoothly complete edge computing, local configuration display and linkage control without screen stuttering or data delay. The whole machine supports wide-temperature operation from -20℃ to 70℃, adapts to 5%-95% RH non-condensing humidity environments, and is equipped with EMC Level 4 electromagnetic protection. Even at photovoltaic power plant sites in deserts and mountainous areas with large temperature differences and complex electromagnetic environments, it can operate stably for a long time without faults such as crashes and disconnections.

In actual use, USR-SH800 can also greatly reduce the operation and maintenance cost of photovoltaic power plants. It has a built-in WukongEdge edge platform, providing a drag-and-drop low-code configuration tool. Without professional programmers, operation and maintenance engineers can quickly complete the customization of the monitoring interface on site, and intuitively display the power generation data, equipment alarms and environmental parameters required by the power plant on the screen. The device comes with 2-way RS485, 2-way RS232, 2-way network ports and 2-way USB interfaces, supports automatic multi-link switching among 4G/Wi-Fi/Ethernet, automatically caches data when the network is interrupted, with a data loss rate lower than 0.1%, which fully adapts to the unstable network status in remote areas of photovoltaic power plants. At the same time, it is pre-installed with the Linux Ubuntu 20.04 system, with built-in Node-RED and OpenPLC, and supports Docker application deployment. It can not only be directly used as an on-site control center, but also connect to the original management system of the power plant, enabling rapid implementation without extra transformation.

At present, USR-SH800 has passed a number of authoritative industrial certifications such as CE, ROHS, WEEE and 3C, and has completed long-term implementation verification in outdoor scenarios of dozens of photovoltaic power plants across the country. Many operation and maintenance personnel have reported that after switching to USR-SH800, they no longer need to hold light shields to view the screen under sunlight, the daily inspection efficiency has been directly increased by 70%, and the previously frequent problems of misreading data and missing alarms have almost completely disappeared.

From the industry pain point that "90% of people have to endure" in the past to the clear, smooth and stable outdoor visualization experience today, USR-SH800, with targeted hardware optimization and full-scenario adaptation capabilities, provides a truly practical industrial control display solution for open-air industrial scenarios such as photovoltaic power plants, smart water conservancy and outdoor security, and also elevates the application experience of outdoor industrial panel PCs to a brand new level.
