High-speed rail maintenance and high-speed rail parts management can not use traditional methods for a long time, and it is necessary to constantly find new technologies to complete daily work to ensure that my country’s high-speed rail business is steadily improved. Judging from the existing work, RFID radio frequency identification technology is currently an important technology that is more respected.
Simply put, RFID radio frequency identification technology is mainly radio frequency identification, which is a more prominent automatic identification technology. In practical applications, by using RFID radio frequency identification technology, radio signals can be used to better identify specific targets and complete accurate reading and writing of relevant data. There is no need to establish mechanical contact between the identification system and specific targets. , There is no need to establish an optical foundation. From the perspective of the technology itself, RFID radio frequency identification technology has many advantages:
(1) The operation of RFID radio frequency identification technology is relatively simple, bid farewell to the previous complicated control, only according to objective requirements, it can complete flexible automatic control, work efficiency and work quality are worthy of recognition;
(2) Using RFID radio frequency identification technology, data can be read more quickly. During the test, the effective identification distance of RFID radio frequency identification technology has exceeded 30m, which is a very suitable technology for high-speed rail maintenance and high-speed rail parts management;
(3) RFID radio frequency identification technology realizes good dynamic real-time communication. During operation, this technology allows the tag to communicate with the reader at a frequency of 50 to 100 times per second. It can be seen that RFID radio frequency identification technology has strong feasibility for practical work.
1 Application of RFID radio frequency identification technology in high-speed rail maintenance and high-speed rail parts management
With the passage of time and the development of society, my country’s high-speed rail business has achieved unprecedented improvement, but there are still many problems to be solved in terms of high-speed rail maintenance and high-speed rail parts management. RFID radio frequency identification technology has achieved great theoretical success, and its own automatic identification technology is also relatively strong, but how to ensure that RFID automatic identification technology can have an ideal effect on high-speed rail maintenance and high-speed rail parts management is very worthy of study.
1.1 System software design
In order to be able to better improve the work level of high-speed rail maintenance and high-speed rail parts management in essence, it is absolutely impossible to implement work based on past experience again. It is necessary to complete maintenance and management work on the basis of a large amount of realistic data. RFID radio frequency identification technology has shown outstanding levels in many aspects. At this time, we can use RFID automatic identification technology as a basis to design software that meets high-speed rail maintenance and high-speed rail parts management to improve work efficiency and work quality. Faced with a lot of work, you can also deal with it calmly. Combining past work experience and current work standards, the author believes that the design of system software should proceed from the following two aspects:
1.1.1 Software development tools. After comprehensive comparison and analysis, it is believed that ASP.NET should be used to complete the selection of software development tools. ASP.NET was launched by Microsoft. Its predecessor was ASP. It inherited the advantages of ASP and improved its shortcomings. It is powerful and can support many languages, such as C++, C#, VB, etc., because C# is commonly used. A language specially designed for ASP.NET, ASP.NET pages are composed of markup and code files. The compiled code is more classic, and the parsing code in ASP has more advantages. In order to take advantage of these advantages, the markup must also be compiled. The compilation process involves two main steps:
(1) Convert the markup to a C# suitable for the ASP.NET class hierarchy;
(2) Compile the temporary into an assembly, and then load the resulting assembly into the application domain hosting the application.
1.1.2 Modular design of high-speed rail maintenance and high-speed rail parts management system functions based on RFID radio frequency identification technology. In a system based on RFID radio frequency identification technology, in the design process, the module aspect is the specific execution part, which is directly related to whether the maintenance of high-speed rail and the management of high-speed rail components will fit the actual development. This article believes that the module design includes the following three aspects:
(1) RFID radio frequency identification technology data management system, the system is mainly composed of a central database and a terminal manager to achieve full control of the system;
(2) High-speed rail parts management information system, the system is mainly to realize the effective management of high-speed rail parts, through the analysis of market conditions, the actual needs of aviation work, the daily stocking volume, the combination of financial conditions, etc., to complete the high-speed rail zero The improvement of parts management level avoids the vicious circle of high-speed rail parts management;
(3) Maintenance engineering system. High-speed rail maintenance is not a simple maintenance. In addition to handling maintenance problems, the system also implements the filing of past problems, the analysis of classic cases, the analysis of special situations, etc., on the one hand, to avoid the recurrence of maintenance problems, on the other hand Provide more reference and guidance for future maintenance and optimization of high-speed rail, and realize the continuous improvement of maintenance level.
1.2 RFID radio frequency identification technology is applied to the process design of high-speed rail parts management
With the rapid development of the high-speed rail business today, the process design of high-speed rail parts management must be as simple as possible and not cause too complicated situations, otherwise it is easy to fall into the past problems, and the losses caused by then will be relatively large. RFID radio frequency identification technology is currently a relatively prominent automatic identification technology. By applying this technology to the process design of high-speed rail parts management, more outstanding results have been achieved. In the current process design, the application of RFID automatic identification technology is mainly completed from the following three tasks:
1.2.1 Storage. Before the new high-speed rail parts are put into the warehouse, they must be numbered according to the type and related information of the high-speed rail parts, and written into the RFID electronic tags through the MT5000 handheld terminal reader, and the generated RFID electronic tag data is transmitted to the central database. Serve other modules.
1.2.2 Replenishment of high-speed rail parts. Position adjustment in the system: Because the warehouse is not always the same, sometimes it is adjusted according to the needs, some need to be moved into the position, and some need to be moved out of the position. The administrator downloads the corresponding instructions in the RFID system operation through the MT5000 handheld terminal.
1.2.3 Inquiry and delivery of high-speed rail parts. When querying related high-speed rail parts, the administrator first checks the catalog number of the high-speed rail parts through the query management subsystem. The system extracts the corresponding data information through the high-speed rail parts number, and sends out the warehouse instruction after the proofreading is consistent. When passing through the warehouse, the UR6258 UHF reader at the warehouse will feed back the information of the high-speed rail parts to the management center in real time. At this time, the system also records the outbound time information and personnel of high-speed rail parts.
