On the evening of July 19, the National Energy Administration released the statistics of the national electric power industry in the first half of the year. By the end of June, the cumulative installed capacity of power generation in the country was about 2.71 billion kilowatts, an increase of 10.8% year-on-year. Among them, the installed capacity of solar power generation was about 470 million kilowatts, an increase of 39.8% year-on-year, and photovoltaic power generation was the main type of solar power generation.

As the core raw material for manufacturing photovoltaic solar cells, monocrystalline silicon plays a vital role in the industry. With the development of solar cells towards large size, ultra-thin and high efficiency, the design concept of the core equipment in the production process of crystalline silicon solar cells - diffusion furnace has also changed from satisfying the process to a humanized design that takes into account both process and environmental protection.

How to make the diffusion furnace equipment achieve full automation, high production efficiency, low-cost diffusion, and humanized operation? Evoc comes to help, making a leading company in the industry hand in a perfect answer sheet.

Evoc’s W15 series industrial tablet computers are installed in the control cabinets of single crystal silicon growth furnaces and polycrystalline silicon ingot furnaces, mainly used for the ingot casting production of solar-grade single crystal silicon growth furnaces and polycrystalline silicon ingots, completing the monitoring and control of silicon body production status, setting of equipment working parameters, statistics and query of historical data, reporting and query of fault records, etc., to ensure the reliable operation of production equipment.

Three major functional features

•PC adopts aluminum alloy material, and the system architecture adopts the motherboard + expansion board design scheme. The structure is simple, and the connection between each module board adopts high-reliability connector docking, ensuring the high-reliability operation environment, which has good dust-proof, heat dissipation and anti-vibration performance.

•Support multiple platforms, such as mainstream platforms: H110/H310/Q370/C236/Skylake-USOC/Bay Trail, etc., support Windows 7(64bit), Windows 10, LINUX and other operating systems.

•This product is oriented to high-end MES, integrated monitoring, automation and other fields, mainly used for production line MES, integrated monitoring (rail transit, building, power, etc.), photovoltaic manufacturing single crystal furnace equipment, wind power and other harsh industrial site control applications.

Four major customer benefits

• Evoc HMI products are suitable for various field control schemes, which not only improve the reliability of the controller, but also provide users with a friendly interface.

• Each part is designed and tested separately, shortening the development cycle and making it easy to upgrade.

• The human-machine interface is rich, which can meet various requirements of customers.

 • Make full use of the original equipment resources of customers, and the upper computer only realizes query, display and statistics and other functions that do not affect control, ensuring that the control system is not disturbed by malicious programs such as viruses and hackers, making the customer's production system and enterprise management system better integrated, and receiving unanimous praise from customers in the industry.
