Description

Technical Field

[0002] Currently, most COMe modules in industrial computers on the market use foreign Intel processors and run the Windows server operating system. However, using foreign processors and computers hinders core control. Foreign processors often have long lead times and high maintenance costs, and most BIOS firmware is incompatible with domestically developed products.

[0003] To address the complex and volatile international landscape and mitigate potential power safety issues, State Grid Corporation of China has proposed building a next-generation, independently controllable substation secondary system based on proprietary chips and a domestically produced operating system. The complete domestication of software, hardware, and communication protocols will ensure complete autonomy and control, ultimately resolving bottlenecks in core technology.

[0004] Furthermore, since industrial computers are typically not connected to the Internet most of the time and only operate within an internal LAN, errors in the timing system's crystal oscillator can cause errors, making accurate timing impossible. Utility Model Content

The power module includes two power supplies and a load balancer connected to the two power supplies respectively. The load balancer is used to control the power supply for load balancing. When one power supply fails, the other power supply is controlled to replace it. After the failed power supply is replaced, the two power supplies are controlled to work together to ensure the reliability of the industrial computer. In an embodiment of the present invention, the chip model used by the load balancer is JW7201. The human-computer interaction module can use a touch screen for human-computer interaction.

In order to generate a high-precision clock signal, the timing circuit uses a latch to latch the arrival time of the Beidou second clock, uses a counter and a comparator to divide the frequency of the high-precision crystal oscillator, and the comparator generates a crystal oscillator second clock signal. The FPGA chip corrects the comparison value generated by the comparator to generate a corrected second clock, and analyzes the phase difference between the corrected second clock and the latched Beidou second clock to generate a deviation sequence between the Beidou second clock and the crystal oscillator second clock, thereby correcting the system clock.

In this embodiment, the octal isolator uses the Shanghai Belling BLD7721AH chip. The serial port expansion card uses the Qinheng CH348L chip, which supports RS232, RS485, and RS422 serial ports.

[0034] To sum up, in the present invention, the data processing module adopts the Beidou time synchronization module, and by receiving the Beidou clock synchronization signal, it corrects its own clock signal to obtain accurate system time; the present invention adopts a modular design, which is easy to secondary development and has a sufficient number of interfaces, thereby improving the maintainability, flexibility and life cycle of the industrial computer; since the power supply module includes two power supplies and a load balancer respectively connected to the two power supplies, when one power supply fails, the other power supply is controlled to replace it. After replacing the faulty power supply, the two power supplies are controlled to work together, thereby ensuring the reliability of the industrial computer; and the industrial computer of the present invention is based on the Zhaoxin platform, and all chips can adopt a domestically produced design to achieve complete independent control.
