Quy trình cho máy tính bảng công nghiệp đang sử dụng là gì?

Because the industrial panel PC has the characteristics of CAN bus interface, data link negotiation interface similar to Mitsubishi, programming status, etc., it can not only build the basic web page with CAN as the main line, but also build the surface web page with RS485 and RS232 bus. system. Applying it to the tunnel kiln system can satisfy both the control of the bottom layer and the monitoring of the surface layer, especially the application of the CAN bus, which makes it very good in timeliness, simplicity, networking convenience and protection. guarantee. Tunnel kiln is a kind of continuous kiln, which is widely used in ceramics, sanitary ware, tile firing, glaze firing engineering, nuclear materials, electronics and other professions. , The quenching zone and the slow cooling zone are composed of four parts. The control of the tunnel kiln involves the control of the fan, the detection and control of the temperature, the test and control of the pressure, and other related controls. The following takes a tunnel kiln in a factory as an example to illustrate the completion process of its control system and the general principles of the system. System requirements: temperature detection and control area, using thermocouple and PCI control; temperature flashing area; fan selection strategy; fan selection includes exhaust fan, combustion fan, rapid cooling fan, exhaust fan, rapid cooling fan, shaft Types such as flow fans; safety interlocking requirements; switching quantity interlocking: hardware interlocking and software interlocking are necessary, and technical interlocking requirements are further implemented during planning; industrial-level human-machine interface is used as the control system. All operations can be completed on the man-machine interface; relevant control information can be transmitted to the computer, and the computer is only used for information resolution, not included in the control; Set graphs, historical trend graphs, and complete report printing performance, historical record interrogation, data storage and other functions. All systems use CAN bus for system wiring and real-time control. The system uses Advantech's IPC843 as a flash-controlled human-machine interface computer (12.1 inches, true color) and an industrial panel computer IPC-810 P4 for monitoring. machine.

Giải thích các đặc điểm của máy tính bảng công nghiệp d25

  The industrial tablet d525 is a common industrial motherboard. Because of its very good performance in some system solutions, it is used on the ground in the current industrial control process. Multi-port interface, software encryption, system The demand for rings is very large, and the industrial tablet d525 can provide a solution. In response to the application requirements of current industrial control and special applications for multi-button ports, software encryption, and system media, especially for 6 or more serial ports, CAN bus, multi-function module built-in access and application software encryption, the ZHXD525 motherboard should be used. and live. Below we analyze several major features of the motherboard, so as to provide customers with more application solutions. 1 full-length minipcI-e and 2 board-length minipce-e included in the main industrial panel computer d525. Times, the half-length can be connected to the end card reader, and with excellent support for web module access. In addition, the industrial tablet d525 also has modules, such as high-definition wireless network card modules, 3G modules, and other multi-functional expansion modules. What needs to be filled here is that most of the USB interfaces of household machinery are very large, but the embedded motherboard in industrial tablet PCs is not the same. It can be said that USB is not strong and stable in the field of industrial control, so it is rarely used. . All in all, in some special fields such as industrial control, multi-function expansion modules usually require multiple minlper-e slots on the motherboard. The encryption of software is widely used in the field of industrial control. The most common method is that an encryption card through the PC is a special board connected to the PC slot that can be independently calculated. The encryption technology is very different. It is difficult to crack. Another technique is to have a section on the BOS of the industrial tablet computer, which can randomly include a password that is not static.

Khi máy tính bảng công nghiệp được kích hoạt, chương trình sẽ quét trùm của bo mạch chủ. Nếu mật khẩu và khóa khác nhau, hệ thống không thể được kích hoạt bình thường. Chỉ có thương nhân của hội đồng quản trị biết mật khẩu. BIOS của máy tính bảng công nghiệp sẽ lưu một vị trí và nó cũng có thể viết thuật toán mã hóa của phần mềm ứng dụng. Khi phần mềm ứng dụng được kích hoạt, thuật toán mã hóa trong BIOS cũng được kích hoạt và chức năng được xuất ra vị trí xác định, được so sánh với chức năng mã hóa của phần mềm ứng dụng để đảm bảo tính hợp pháp của ứng dụng phần mềm. So sánh mã hóa BOS của bo mạch chủ và mã hóa thẻ PCl, cần phải gói bo mạch chủ và phần mềm để mã hóa, nhưng không cần tăng chi phí, miễn là BOS của bo mạch chủ có hiệu suất mã hóa là được. Nhiều bo mạch chủ d525 máy tính bảng công nghiệp có đặc điểm này.
