Research on Teaching Mode and Skill Level of Railway Transportation Specialty in Higher Vocational Education Based on Computer Working Process

With the development of railway industry in China and the arrival of the computer age, there is a large talent gap in the direction of railway transportation in China. In order to increase the teaching quality of railway transportation major in higher vocational colleges and the skill level of students, it is very useful to apply the computer working process in the education of railway transportation major. This study discusses the teaching situation of traditional railway transportation mainly in higher vocational colleges, the necessity of computer working process in railway transportation, and the teaching mode and skill level of higher vocational railway transportation specialty based on computer working process. it provides a method for the new teaching mode of railway transportation.


The current situation of railway transportation major in China
With the increase of railway investment in our country, railway transport enterprises are in urgent need of a lot of high-skilled talents, and the shortage of railway high-skilled talents is very serious. The percentage of senior workers and technicians in the total number of skilled labours has a large gap compared with the national average, and it is even more far away from the developed countries. And the railway high-skilled workers are aging seriously, and the skilled personnel team is out of gear. At present, the students trained by the teaching mode of higher vocational colleges put more eyes on the mastery of theoretical knowledge and the lack of practical operation ability, which lead to the students can not better meet the needs of enterprises [1] .

The curriculum is out of touch with the actual needs of the job
Vocational education is the key to development. The curriculum system of vocational education should be designed according to the actual needs. But the reality is that the curriculum design of most colleges and universities is out of touch with the actual needs. Because the design of the curriculum system still follows the traditional theoretical teaching mode, the practical needs are not fully taken into account, the proportion of practical teaching courses is small, and there is no substantial innovation in teachers' ideas and teaching forms. as a result, the current professional teaching is still based on theoretical indoctrination. To some extent, although theoretical study is a required course to consolidate the professional foundation, too much emphasis on theory and light on practice will not be able to fit the requirements of modern market economy. Therefore, the practical ability of the trained talents is not strong, and there is a big gap with the actual needs of the society.

Unified textbooks are mainly used in the use of teaching materials
According to the learning objects and learning objectives, the teaching materials fail to develop teaching materials with strong pertinence, focusing on hands-on practice and fully in line with railway transportation, and fail to reflect student-oriented, so it is hard to increase students' interest in the education. Teachers are used to organizing lectures due to the selected teaching materials, but they are not good at studying the role of teaching content in professional training goals, and they are less good at studying how to combine teaching content with students' future work.

The training conditions are far from being able to fit the requirements of higher vocational education
For example, the passenger and freight training room does not have the training conditions of the simulation site, and lacks the necessary training facilities and professional software.
The school's training equipment is insufficient, most of the training is completed in the school training base, rarely to the railway transport enterprises for internship. Even if there is, it is generally based on passenger transport internship, and there are few practical opportunities for several other professional core courses. Especially for the positions involved in railway operation, students majoring in railway transportation are rarely able to go to the railway site to carry out post practice.

Skill research can not meet the needs of railway transport enterprises for high-skilled talents
In addition, the examination rate of the students is low, and the passing rate is also low.

The cooperation between colleges and companies stays in the primary stage.
Transport enterprises are generally willing to carry out school-enterprise cooperation only when a large number of people are needed for Spring Festival and summer transportation, but they are usually reluctant to accept students, and even the cooperation during Spring Festival and summer transportation is mostly temporary in nature. it is not based on long-term cooperation. Moreover, the number of students who can participate in it is only a small number, and most students do not even have the opportunity to do so.

The necessity of computer working process in railway transportation
At present, it is the era of big data, and computers are widely used in various fields. Computer information network system is also widely used in the procedure of transportation management. Computer information network technology has high penetration and integration ability, so it provides technical support for transportation management, which can not only optimize the allocation of relevant resources, but also reduce the pressure of transportation to a great extent. significantly improve the overall efficiency of transportation [2] .

Rationality
The design of computer information network system requires a comprehensive investigation of the specific business of transportation management, and then reasonably adjust the current business system.

Reliability
Whether the computer information network system can run stably or not is the key index to evaluate the function of the system. The redundant function should be strengthened in the process of designing the computer information system for transportation management. After making the software, it is necessary to test to eliminate the hidden trouble and strengthen the self-test function of the computer information network system.

Practicability
The computer information network system in the procedure of transportation management needs to be combined with its own needs, in-depth analysis of the functions of the computer information network system, highlighting the key points and main aspects, to avoid the emergence of computer information network system with powerful functions but not fit the need of the actual situation of transportation management.

Expandability
When designing the computer data network system, it is necessary to take a long view and foresee the problems that may exist in the procedure of transportation management. From the perspective of hardware design, it is necessary to reserve some space to provide a guarantee for the long-term development of transportation management and update the hardware in a timely manner. In the aspect of software design, it is necessary to adopt modular structure or hierarchical structure to create good conditions for the functional development of computer information network system.

Advantages of computer working process in railway transportation summary application
Computer information network system can promote the overall efficiency of transportation management in order to more easily grasp the relationship between enterprises, it is useful to make rational use of computer technology. For example, in the process of railway transport management, computer information network system is able to be used for network management, which can not only save passenger time, but also improve the management efficiency of the railway department. Computer information network system can actively guide small enterprises to continue to take the road of intensive development, today's market economy shows a diversified development trend, small enterprises want to gain a firm foothold in the market, they must rely on a lot of information resources to reduce costs. At this time, the computer information network system can help enterprise managers to grasp the timely market information, and then reasonably analyze the current economic market development prospects. In addition, help small enterprises standardize their daily business and promote small enterprises to continue to take the road of intensive development. In addition, the using of computer information network system can not only promote the overall work efficiency of the railway dispatching center, but also actively improve the working environment of the staff. The computer data network system can collect the route and condition of the railway, provide the collected information to the leaders. The computer information network system can also operate effectively in the railway dispatching center, automatically handing scientific processing means to the railway dispatchers, constantly improving the overall work efficiency of the relevant workers, so that the railway transport capacity can be brought into full play. Taking daily report management as an example, the application of computer information network system to transportation daily report can significantly improve the efficiency of daily report and ensure that the specific application value can be effectively improved. Therefore, it is necessary to fill in the daily report management in the computer information network system, deal with the traffic project in time, and use the report to process the relevant information to ensure that the transportation system can run effectively [3] .

Teaching mode and skill level of railway transportation specialty in higher vocational education based on computer working process
At a time when all industries and production links are being interconnected, all industries are trying to achieve industrial transformation and upgrading with the combination of big data and cloud computing technology. The railway has already started work in this area, and preliminary results have been achieved. In the process of cooperation between railway and information technology enterprises to resolve problems, it is significant for railway practitioners to control the basic knowledge of computer technology in order to make the participants of information technology enterprises understand the problems that need to be solved. In addition, in daily production, if railway practitioners can have good computer technology, they will be able to replace people to complete a lot of daily repetitive work. This not only reduces the work intensity and improves the efficiency, but also helps to improve the work reliability. Therefore, in order to use this requirement, the undergraduates trained by colleges and universities should not only know what computer technology they have, but also understand and master the basic computer technology [4] .
Recently, the education of railway transportation major in higher vocational education based on computer working process has some limitations: (1) The connection between theory and practice needs to be improved; (2) The relationship between practical teaching content and practical engineering problems needs to be strengthened; (3) The mutual support between computer technology courses needs to be strengthened; (4) The course assessment system should better adapt to the characteristics of computer technology courses.
Therefore, the railway transportation major in higher vocational colleges needs a new education mode, so as to increase the skill level of students and teachers. Integrated teaching is a great method to integrate the computer working process into the teaching process [5] .  Figure 2. The design process of integrated teaching task. The adoption of integrated teaching can not only urge teachers to constantly master novel knowledge, new technology and new technology in the teaching process to meet the requirements of integrated teaching content. And this can urge teachers to constantly explore new teaching methods in the teaching process to improve the effect of integrated teaching, so that teachers' teaching ability and teaching level can be continuously improved. Secondly, through integrated teaching, we can break the traditional teaching and evaluation model, mobilize students' subjective initiative, cultivate students' comprehensive ability to analyze and resolve problems, and activate the classroom atmosphere. In addition, the adoption of integrated teaching can not only make use of teaching space and teaching time, but also take teachers as the lead and students as the main body [6] .
The implementation of integrated teaching in the major of railway transportation management is the need for vocational colleges to cultivate students' post professional ability development. it is the cultivation of railway professional ability which is necessary to train students majoring in railway transportation with the combination of theoretical knowledge and practical ability. The implementation of integrated teaching in the major of railway transportation management mainly starts from five aspects: the training of integrated teachers, the selection of integrated teaching content, the organization of integrated teaching, the preparation of integrated teaching resources and the evaluation of integrated teaching.

Conclusion
Undergraduates majoring in railway transportation should master a solid foundation of computer technology. In the specific teaching process, we should proceed from the actual problems of railway production, through the design of problems with a certain depth and breadth to enable students to deeply understand the basic concepts and technical principles.
It can also exercise students' ability to apply what they have learned to solve practical problems. In addition, by adjusting the assessment methods to adapt to the characteristics of teaching and computer technology courses in order to achieve better results, through adjusting the teaching methods in the teaching link to cultivate students' habit of continuous learning in order to adapt to the characteristics of rapid upgrading of computer technology.
