The text reading module is based on FATFS, compared with the traditional character string matching mode. The invention adopts a mode of an offset address table, stores the offset address required by inquiring the alarm text information in a first file, and searches in a second file by accessing the offset address of the first file. The retrieval speed is improved, the system is operated more smoothly, and the occupation of resources of the embedded system is reduced.
The OpCUA client adopts an OPEN62541 protocol structure, FreeRtos and LWIP are loaded as a basic real-time running environment of the OPCUA protocol, and when the processor 1 uses the OPCUA client, MbodTLS is transplanted to use an information key to encode and decode information, so that the OPCUA client can be in encrypted connection with an OPCUA server in a machine tool.
The FreeRTOS is a mini real-time operating system kernel. As a lightweight operating system, the functions include: task management, time management, semaphores, message queues, memory management, logging functions, software timers, coroutines, etc., can substantially meet the needs of smaller systems. LWIP (Light Weight Internet Protoco1) is an open source TCP/IP protocol stack for embedded systems developed by Swiss Computer Science Institute of Computer Science (Swedish Institute of Computer Science) AdamDunkels et al. The meaning of LWIP is the Light Weight IP protocol. The LWIP can be transplanted to an operating system or can be independently operated without the operating system. The emphasis of LWIP TCP/IP implementation is to reduce the RAM footprint while maintaining the primary functionality of the TCP protocol. Generally, the LWIP protocol stack can be operated only by a RAM of dozens of KB and a ROM of about 40KB, so that the LWIP protocol stack is suitable for being used in a small embedded system.
MbodTLS is an open-source, portable, easy-to-use, high-code-readability SSL library. Common encryption/decryption algorithms, x.509 certificate operations and TLS/DTLS protocols can be implemented. Each functional module of the system is relatively independent and low in coupling, can be defined and cut by configuring a macro, and is very suitable for an embedded system.
There are some machines, such as siemens 828d for example, which refuse to log in anonymously, and when using the opua client, the migration mbidtls encodes and decodes information using the information key, so that the opua client can make an encrypted connection with the opua server in the machine. By realizing the OPCUA protocol stack, the universality of the whole system is enhanced, the application environment of the device is improved, and secondary repeated development is reduced.
For the Siemens 828d machine tool, the connection can be completed by inputting a certificate and a secret key in a corresponding format when the OPCUA client is connected with the machine tool in an encryption mode.
As shown in fig. 16, the structure of the opua client is schematic. The basic information model of the OPCUA provides a foundation for the information modeling of the OPCUA. The information model of the opuca is expressed by a tree mechanism, and mainly includes node types, node attributes, and node relationships. The service of the opuca includes connection service, editing and browsing of an address space, real-time reading and writing and subscription, reading and updating of historical data, and calling of method nodes, which are common and have event triggering and alarming. These functions are all composed of messages generated by the request, reply mechanism of the opua protocol stack.
After the OPCUA client reads the alarm number, the device automatically reads the offset address corresponding to the alarm number, and after the offset address is obtained, the text information corresponding to the offset is read through the SEEK function of FATFS. Because Chinese is required to be displayed, special attention needs to be paid to the fact that Chinese characters in the embedded system and the second file need to be set to be UTF-8 to be matched with a Chinese character library, and the phenomena of messy codes and the like are avoided.
Finally, it is noted that: the above-mentioned embodiments are only examples of the present invention, and it is a matter of course that those skilled in the art can make modifications and variations to the present invention, and it is considered that the present invention is protected by the modifications and variations if they are within the scope of the claims of the present invention and their equivalents.
