Main technical content: The standard extracts the common features of mainstream ticket systems in the industry and forms a universal technical architecture, which is practical, complete, and instructive. The standard fully considers the trend of technological development, combines new technologies and applications, and takes into account advancedness. It designs technical specifications from the perspectives of the structure, function, performance, interface, and security requirements of the ticket system, and the level of preparation reaches the granularity of providing technical specifications, models, and performance indicators, which can meet the needs of guiding the design of ticket system solutions, preliminary design, and construction design. I. Clarify the composition of ticket codes. It is necessary to consider the information capacity of the code. Initially, the code was expected to include the scenic area code, ticket type code, activation date, expiration date, reservation period, number of visitors, document type, and checksum. The code length once reached 52 bits. However, it is also necessary to consider the efficiency of ticket inspection, recognition, and storage. Excessively long codes will lead to complex QR code graphics, slow recognition rates, and poor ticket inspection throughput. Ultimately, an optimization and balance between the two was achieved, resulting in the current 22-bit base 62 code, which can be shortened to 12 bits after compression. II. Clarify the technical architecture of the ticket system. This standard provides a template for the technical completeness, functional completeness, and network rationality of the ticket system, which can guide the construction and upgrade of ticket systems for users in the scenic area industry. III. Standardize ticket reservation under the background of the normalization of the pandemic. Through reservation inventory management, the ticket system realizes dynamic control of total quantiti
