Second, the key points of autonomous control of AWP 100 intelligent control platform
The localization of PLC controller is mainly reflected in the autonomous control of its technology. Autonomy and controllability are mainly reflected in:
1. The controller design needs to be autonomous and controllable
In the initial design of the controller, its design specifications and design schemes are completely completed by the domestic.
2. The controller hardware design is autonomous and controllable
In the initial stage of hardware design, the controller formulated the principle of autonomous control, and tried to choose domestic electronic components under the premise of meeting the design requirements.
3. The controller operating system is developed and controllable
The Fowler-based OS used in the controller is developed based on the linux3.0 version, adding the self-developed security kernel, network firewall, user manager, etc., and realizing the autonomous controllability of the operating system under the premise of safe and reliable operating system. And Foxford New Energy completely completes the iteration of the OS operating system, new function development, new technology application, etc.
4. Independent development of controller production and test equipment
In order to ensure the high reliability of AWP100 controller, Foxton New Energy cooperated with domestic manufacturers to independently develop the ATE (PCBA automation test equipment), TST (environmental adaptability test equipment), ATS (product function automation test equipment) and so on.
5.
Domestic production of controllersThe controller is completely produced by the Shanghai factory of Foxford Technology, and its procurement, quality control, customer delivery, etc., are completed locally.
6. Controller technical support autonomous controllable
The technical support of the controller to the client is completely completed by Fuchs technology, which promises that the customer must reply within 6 hours when he needs support. When he needs to go to the field service, he will arrive at the scene in 12 hours in major cities across the country, 48 hours in non-remote areas, and 72 hours in various sites across the country.
7. The after-sale maintenance service of the controller is controllable
The cause analysis of controller damage and the repair of bad parts are completely completed by the Fowlard technology.
Third, the breakthrough technology of AWP 100 intelligent control platform
A. High-security network protection system
1. Secure external network communication protocol
The AWP100 controller uses encrypted network communication protocols, such as SFTP, Https, and SSH.
2. Enhanced built-in firewall
The AWP100 controller uses an enhanced firewall that allows only authorized external devices with unique IP addresses to access the controller.
3. Secure built-in web server
The AWP100 controller uses a secure built-in network server. When external attack data penetrates the firewall, the network server automatically cuts off the network connection between the external device and the controller to ensure the stable operation of the controller.
4. Built-in security kernel
The operating system of the AWP100 controller has a built-in security kernel. When external network attacks penetrate the above three layers, the security kernel will disconnect the controller file management system, cut off all external network services of the controller operating system, and only keep the controller system running.
B. Dual-system hot backup controller redundancy system
In order to ensure the continuous and stable operation of the controller in the conditions requiring high reliability, the AWP100 controller will introduce a dual-system hot backup controller redundancy system to ensure the continuous and stable operation of the control system using the AWP100 controller.
C. High security real-time operating system
The AWP100 controller uses the dedicated Foxtons OS operating system. The OS is based on the open source real-time Linux3.0 platform. Foxtons New Energy has enhanced the safety
design of Foxtons OS system.
1. Basic security module
The basic security of Linux is based on the Linux security module, SELinux, and Winbind, and a variety of access control mechanisms are built on LSM to isolate applications from the operating system. The basic security of Windows is based on MSCAP, MSCAP can trust many root authentication authorities, and the system is relatively fragile.
2. Network security
Linux provides full support for the current TCP/IP protocol, and the kernel also includes IP firewall code, IP anti-counterfeiting, IP quality of service control, and many security features. Therefore, Linux is better than Windows in terms of network security.
3. Kernel security
Windows integrates the user program with the core of the operating system, while Linux separates the core area from the user area. When something goes wrong with a user program, it affects the window kernel, but it doesn't affect the Linux kernel at all. Therefore, linux kernel security is better than Windows.
4. User management
In the Windows system, users log in as the system administrator by default, and any damage that occurs in the system will quickly spread throughout the system. Linux is a multi-user operating system, so even if one user wants to do malicious damage, the underlying system files are still protected.
5. Architecture security
Linux systems are modular in design, and you can remove any system component if you don't need it. The Window is a whole, even if there is a security vulnerability of the module, in the window system can not be deleted. Therefore, Linux is better than window in terms of architectural security.
4. Operation performance of AWP 100 intelligent control platform in wind power industry
By 2022, there are more than 17,000 units of autonomous and controllable domestic controllers operating in various regions of the world, with the highest altitude of 4133 meters and the lowest operating temperature of minus 37 degrees, and the stable operation in China's two major thunderstorm areas. A large number of offshore wind farms such as Zhuanghe in Dalian, Changyi in Shandong, Jinou in Vietnam and Calais in Vietnam are in stable operation.
