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.

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.
Коли промисловий планшетний комп'ютер активується, програма сканує бос материнської плати. Якщо пароль і ключ різні, система не може бути активована нормально. Пароль знає тільки продавець дошки. BIOS промислового панельного комп'ютера збереже місце, а також може записати алгоритм шифрування прикладного програмного забезпечення. Коли прикладне програмне забезпечення активовано, також активується алгоритм шифрування в BIOS, і функція виводиться у вказане місце, яке порівнюється з функцією шифрування прикладного програмного забезпечення, щоб забезпечити легітимність програми. Порівнюючи шифрування BOS материнської плати та шифрування плати PCl, необхідно об’єднати материнську плату та програмне забезпечення для шифрування, але немає необхідності збільшувати вартість, якщо материнська плата BOS має продуктивність шифрування, це можливо. Багато промислових планшетів d525 мають таку характеристику.
