Challenges and trends of single crystal furnace control
The production of monocrystalline silicon in monocrystalline furnace takes dozens of hours, and the whole control can not tolerate any error, precision and stability are indispensable;
There are hundreds of single crystal furnaces in a factory, and the program and firmware upgrade consume power and are easy to leak, which is easy to leave security risks;
The demand of manufacturers for low energy consumption and process optimization of single crystal furnaces is increasing, and the industry urgently needs to optimize production through digital means.
The PAC integrated control system program exclusively developed by Huichuan integrates the axis control and logic control of PLC, as well as the vision system and human-computer interaction system in the industrial computer, all in the PAC.

Huichuan PAC “double engine” control system, the importance of safety, comparable to the dual engine configuration of civil aircraft, for the control of single crystal furnace to bring unprecedented high safety and reliability: 01 system isolation and independent deployment
Huichuan PAC integrated controller solution, through the “virtualization” technology to effectively isolate the hardware, realize the independent deployment of the user system and the control system, to ensure that the two do not interfere with each other, so that the PLC system is no longer affected by the load rate changes of the Windows system, blue screen restart still do not stop.
Data security and system recovery
With “virtualization” technology, users can safely back up key data in the PLC such as recipes, power failure data and user programs to a hard disk or server, ensuring that important data is kept forever.
PAC has a system quick recovery function, complete backup of the control system and user system, when the control system problems can be quickly restored within 3 minutes.
Accurate and efficient maintenance of thousands of equipment at a time
Huichuan PAC can realize program centralized control upgrade to solve batch upgrade problems, and complete the issuance of hundreds of equipment programs or firmware at one time, which not only reduces 99% equipment upgrade time, but also completely avoids missing upgrades and wrong upgrades.
The centralized control function can view the download time, program version and operation status of all single crystal furnaces in the factory in real time. Click the unified upgrade command to upgrade uniformly, without the need to upgrade one by one like the traditional scheme, which greatly saves the equipment upgrade time.

Avoid device program leakage upgrade, wrong upgrade
PAC centralized control software can display workshop equipment current program version, upgrade time and other information, visual interface makes management at a glance, completely avoid error and leakage upgrade hidden dangers.

810-001489-016 One step ahead all the way
In the single crystal furnace control scheme, manufacturers must consider two points:
● The convenience of rapid development of the solution and subsequent transformation and upgrading;
● Improve product quality and reduce energy consumption through continuous process upgrading.
Huichuan PAC integrated control system solution allows you to:
Rapid development and convenient upgrading
Huichuan PAC controller is highly integrated, one can complete the entire solution development, greatly shorten the software and equipment assembly development time, accelerate project delivery.
PAC has powerful performance and rich communication interfaces, supports flexible configuration and expansion, and reserves space for subsequent upgrading. Users can quickly complete the upgrade operation without replacing the entire control system.
Optimize production with data to achieve high quality products
High speed data channel:
PAC controller replaces the traditional Ethernet communication between PLC and industrial computer through the shared memory board level high-speed communication function, which significantly improves the communication speed. It also provides real-time data acquisition interface and data storage capability to obtain richer production data information, and users can efficiently analyze key production data in real time.
Data storage Services:
Process parameters such as temperature, humidity, pressure and lifting speed are collected and stored through PAC’s big data storage, which provides data base for process optimization. Through big data analysis, the causes of crystal growth problems such as cracks, impurities and diameter inconsistencies are identified, and the production process is optimized to ensure efficient, high-quality and low-energy crystal growth.
