Introduction
The national economy is in a period of transformation and upgrading, and there is an urgent need for a large number of high-quality skilled talents in the electronic manufacturing industry. The Ministry of Finance and the Ministry of Education (2019) issued the opinions on the implementation of the plan for the construction of high-level higher vocational colleges and majors with Chinese characteristics (hereinafter referred to as the " Double-High Plan "). In the construction, we will vigorously support the development of high-quality higher vocational colleges and professional groups in terms of policies and funds through urgently needed technologies and talents based on high-end industries and high-end industries. Building a high-level professional group is one of the main construction tasks of high-level higher vocational colleges. The key to promoting the improvement of higher vocational education is to actively build a high-level professional group (Migao Lei and Guo Fuchun, 2019). Based on the actual situation of the college and in accordance with the requirements of the Ministry of education in the construction of double high colleges, promoting the connotation construction of high-level professional groups has become the key work actively engaged in by higher vocational colleges. The Chongqing municipal government of China has also launched the implementation plan for intelligent manufacturing (2019-2022), which clearly requires that local talents should be actively cultivated. Based on the construction tasks related to intelligent manufacturing, the specialty settings of relevant colleges and universities in Chongqing are adjusted adaptively. Promote the construction of school enterprise industry double bases, professional colleges, enterprise studios, practice bases and many other projects to the greatest extent. At the same time, we also need to actively promote the cultivation of skilled talents to significantly strengthen their cultivation.
Compound skilled talents must be connected with the needs of regional advantageous industrial clusters. In accordance with the principle of "consistent service orientation, jobrelated, complementary professional advantages and professional resource sharing", they should take the core majors as the object, play their exemplary role and further drive the development of other majors (Tang Dan, 2010). The construction of professional groups in higher vocational colleges needs to innovate talent mode, form a new curriculum system, reform teaching materials and teaching methods, and create an intelligent teaching resource bank. The establishment of high-quality teacher team is the core of the development of professional groups, and the practical teaching base is the basis of the development of professional groups (Su Hong, 2021). Building a professional group needs to make it fit the attributes of occupation, openness, system, education and so on. It should be analyzed from the perspective of management and organization mode. Clarify the six construction tasks of professional group construction in professional structure, curriculum system structure, practical teaching base, structured teaching team, school enterprise cooperation service platform and multi-party collaborative development mechanism, so as to make the construction of professional group more systematic (Wu Shenggang and Guo Qingzhi, 2019).
The double high plan is to scientifically connect professional groups and industries, clarify the era logic between the two, and then give a scientific docking path. By strengthening the construction of professional groups, secondary colleges and departments can get a higher level of reform, so as to significantly enhance the vitality of colleges and departments. We should highlight the scientific correspondence between industry and professional groups. In addition, the progress of higher vocational education, society and industry is also closely related. Different regions also need to jointly build different industrial structure layout according to the resource structure, and this structure will also affect the corresponding training specifications and systems (Nie Qiang, 2020). The key to creating a professional group is that higher vocational colleges should be based on the local economy and the logical relevance of industry and professional knowledge. They should better highlight the characteristics and positioning of the discipline. In addition, they should clarify the primary and secondary relationships of different majors in the group. The specific principles are: similar job groups, industry and discipline basis (Ding Zongsheng, 2014).
Through the study of literature, it is found that: with regard to the construction of professional groups, it emphasizes the construction level of teachers in Higher Vocational Colleges and the training conditions of college students; Specialty group is a collection of different specialties through many similar specialties, technologies and posts; Professional groups integrate industry and education in combination with relevant industries. "Core specialty driving" emphasizes the ultimate purpose of specialty group construction and the practical significance of specialty group construction. It is believed that one core specialty drives 3-5 specialties, so that different specialties can interact better. They promote and depend on each other, and can form a joint force well; Build a higher comprehensive quality teacher team (Double Teachers) guided by professional post needs and backbone majors; Carry out the training of skilled talents with the "double subjects" of enterprises, so as to improve the comprehensive strength of higher vocational colleges, further enhance the contribution of professional groups in the field of local economy and serve the social development well. Chongqing C vocational college mainly strengthens the construction of electronic intelligent manufacturing professional group from the aspects of talent training mode reform, curriculum system, teaching staff, practical teaching base, industry education integration and so on.

Reform of Talent Training Mode
As the dual core and engine power of the construction of high-level higher vocational colleges, specialty construction and talent training, clarifying the relationship between them and promoting their coordination and unity should become the core thrust to clarify the motivation of the reform of talent training mode in high-level higher vocational colleges (Chen Enlun and Ma Jianyun, 2020). Under the background of the "Double-High Plan", the goal of higher vocational talent training mode is to vigorously promote industrial, regional economic and social development, and better meet the job requirements. According to the actual situation of students, we need to cultivate compound, personalized and forwardlooking high-quality skilled technical talents who meet the needs of employment through the formulation of flexible school system, diversified learning paths and independent curriculum selection, Enable students to have strong career transfer ability and sustainable development ability, and maximize the influence of domestic higher vocational education. Facing the urgent need for talents in strategic innovative industries and advanced manufacturing business, we took the lead in introducing the pilot work of "1 + X" certificate from the three majors of microelectronics technology, electronic information engineering technology and communication technology, and closely related it to the construction of courses, majors and teachers. When formulating the talent-training plan, we integrated the training contents, teaching related contents and optimized curriculum of the certificate.

Innovatively Implement the Talent-Training Mode of "Learning Post Integration and Gradual Progress By Stages"
The college and enterprises jointly establish talent training objectives and talent training specifications, jointly build curriculum system, build teaching resources and implement talent-training plan, so as to realize the integration of teaching standards and production standards, professional technology and production technology, and professional culture and enterprise culture. According to the post ability, the teaching process is divided into four stages: Post recognition, post following, post rotation and post replacement. In the stage of post awareness, complete the basic humanistic quality, corporate culture and other courses in the college, carry out workplace experience learning in the enterprise, form the preliminary cognition of the enterprise post, form the production capacity of the basic post, and form the basic professional ability and quality. In the post following stage, teachers in the college are the main, supplemented by the implementation of enterprise masters, jointly implement teaching, and carry out skill training around the corresponding posts of students' majors to form professional post ability. In the stage of job rotation, enterprise masters and college teachers jointly implement teaching, and students rotate in various posts in the production process to comprehensively learn the technical skills of various posts. In the post placement stage, the technical training of production posts is carried out in the internship enterprise, focusing on the teaching of technical skills of the master of the enterprise and assisted by the teachers in the college, so that the students can master the professional and technical ability required to complete the work tasks in the post placement stage, improve the comprehensive professional quality, and become the prospective employee before graduation. Deepen the pilot work of modern apprenticeship talent training with Siemens, Haier and other enterprises.

Track the post group, carry out the core task analysis of representative professional posts, and jointly establish and update the content of technology and knowledge with the enterprise. Optimize the talent-training plan of each specialty, revise it every academic year, and form a mechanism for dynamically adjusting the talent-training plan. We will promote the reform of the credit system. According to the requirements of the credit system, credit recognition and conversion standards are formulated and credit replacement is implemented from the dimensions of moral and intellectual education, 1 + X certificate, skill competition, scientific and technological innovation competition and scientific research ability. Students choose corresponding modules according to their majors. Explore cross specialty courses, minor in the second major, and implement a flexible college system.

Build A "Platform + Module" Curriculum System
The core content of the professional group includes the way of curriculum system construction and the composition structure of curriculum resources. The construction of curriculum system should first analyze the technology and service fields faced by the professional group, clarify the talent needs and training objectives, and determine the professional group curriculum group by analyzing the job group tasks (Chen Xiuzhen, 2015). To build a professional group, we should comprehensively consider the applicable courses, disciplines and majors of logic, and also create it flexibly according to the needs of disciplines and professional development. The professional curriculum system mainly involves different modules such as expansion ability, comprehensive practice and professional direction (Li Zhonghua, 2020). Conduct scientific analysis on the ability requirements of the post group, so as to reasonably construct the relevant curriculum system combining each teaching module with the platform. Build three platforms: general courses, professional courses and expansion courses. According to different technical directions, students select corresponding modules to realize the mutual selection of toplevel modules. The middle-level modules can be separated, while the bottom modules are shared by professional basic courses.

Colleges and Enterprises Jointly Build, Open and Share High-quality Curriculum Resources
Introduce national standards, foreign advanced vocational qualification standards and enterprise industry certification standards, effectively integrate new processes, technologies and norms, formulate modular curriculum standards, build teaching resources with MOOC as the core, and build information-based courses such as online open courses, highquality resource sharing courses and online and offline hybrid courses.

Deepen the Integration of Industry and Education
The integration of industry and education involves many aspects. Including government level, industry level, enterprise level, students, colleges, etc. In the context of double high colleges, the integration of industry and education in higher vocational colleges has been paid attention to in recent years, which is conducive to providing a lot of talent support for the future development of enterprises (Zhang Guoli, 2020). Through the in-depth development of the integration of industry and education, it plays a positive role in improving the quality of education, realizing economic transformation, strengthening economic development, enhancing entrepreneurial enthusiasm, increasing employment and many other fields.

Create A Joint Model of "Government, Industry, Enterprise and College"
Make the four parties contact effectively, clarify the responsibilities and obligations of all parties, and they participate in talent training together. Through the efficient integration of different types of resources, colleges and enterprises can truly become a community of common destiny. Government functional departments give full play to their role in resource allocation and scheduling, and encourage enterprises to actively participate in Vocational Education in the form of tax relief or vocational education subsidies. Enterprises and colleges use the talent resources of both sides to set up relevant technical teams in technology research and development, teaching equipment, teaching management software development and other aspects as needed to make breakthroughs in key technologies.

Build A Collaborative Education Mechanism Between Colleges and Enterprises
Let the teaching of higher vocational education be closely and efficiently integrated with the industrial development of society. In the process of educating people, we should implement and strengthen the dual subjects of colleges and enterprises. Strive to achieve more effective reproduction of students' teaching scenes, classroom teaching contents and production scenes, production management and processes in enterprises, so as to synchronize the production services of enterprises with the teaching cycle of classroom disciplines in colleges. At the same time, both colleges and enterprises fully implement the timely and effective dual mode in terms of teacher allocation, teaching venues, student (Apprentice) selection, semester teaching plan, semester teaching process implementation and semester teaching quality evaluation.

Promote the Coordinated Development of Professional Clusters and Industrial Chains
Vocational education and regional industries need not only coordinated development, but also innovation. If vocational education wants to have vitality, it must develop in coordination with the regional industrial chain. This requires vocational education to actively adapt to the development of industry in the process of development. The training object of vocational education is to meet the technical needs of local industries for talents. Of course, local industries also provide important support and effective guidance for professional construction. Therefore, the professional group and industrial chain should be organically coordinated, so that the target industries, emerging industries and pillar industries can be comprehensively and harmoniously developed, so as to create a community of interests integrating industry and education in local areas. The vocational education specialty is closely combined with the industry, and the industry can further drive the professional development and form a spiral development.

Build A High-level Integrated Development Platform of Industry and Education
A high-level industry education integration and collaborative development platform should strive to realize the integrated development of higher vocational education and industry. In the process of its platform construction, it should give full play to the functions of the platform in the following three aspects: first, enterprises with stable cooperative relations and related professional directions should form deep cooperation between colleges and enterprises. This requires that the industry education integration development platform can carry out in-depth cooperation between colleges and enterprises, explore new development cooperation modes, and provide an internship base for new cooperation paradigms. Second, we are willing to provide necessary support for talent training in Colleges and universities. This is the fundamental starting point and foothold of Higher Vocational Colleges in the implementation of the integration of industry and education. This requires the integrated development platform of industry and education to strengthen the cultivation of talents in the cultivation of students' professional spirit, the edification of corporate culture, the accumulation of professional and technical skills, innovation and entrepreneurship education, engineering practice and so on. Third, provide important support for the development of regional industries and industries. In the market economy, the first thing enterprises need to consider is their own income. If the cooperative relationship with colleges can not bring them benefits or tangible and intangible value, the motivation of enterprises to participate in vocational education is insufficient. This requires the establishment of an industry education integration development platform, which can improve production technology for enterprises, train new employees for cooperative enterprises, and provide enterprises with urgently needed technical employees. Through the platform, the professional teachers of the college need to give full play to their professional expertise to provide solutions for enterprises to solve the technical problems encountered in the process of production and development. The college gives full play to the advantages of human resources to provide key training for new employees according to the needs of the enterprise. The students trained by the college can keep up with the technology and ability requirements of enterprises for new employees.
