Description

Technical Field

[0001] The present invention relates to the field of catering, and more specifically, to a meal ordering system and method capable of realizing dish monitoring. Background Art

[0002] In today's catering industry, especially hot pot restaurants, with the continuous improvement of consumer demand and increasingly fierce market competition, traditional ordering and management methods have been unable to meet the dual needs of efficient restaurant operation and high-quality customer experience.

[0003] Traditional restaurants are prone to low order efficiency during peak hours due to insufficient waiters, which causes customers to wait too long and affects their dining experience. In addition, traditional ordering methods usually rely on paper menus and manual records, which are prone to problems such as wrong orders and missed orders, resulting in low operational efficiency.

[0004] In recent years, the application of digital and intelligent technologies in the catering industry has gradually become popular. Emerging technologies such as scanning code to order food and intelligent settlement are changing consumers' dining habits and restaurant operating models. However, the existing system usually only implements a single function and lacks comprehensive management and monitoring of the entire dining process, especially in the process of taking and settling dishes, which is prone to problems such as inaccurate data and opaque settlement. In addition, inventory management often relies on manual experience and cannot achieve real-time monitoring and intelligent replenishment, which increases the difficulty of restaurant management.

[0005] Therefore, in order to solve the above problems, improve the ordering efficiency, management level and service quality of hot pot restaurants, and meet the needs of customers and restaurant managers, it is of great practical significance to develop an ordering system and method that can realize dish monitoring.
