Technical Field
The invention relates to the technical field of Internet of things, in particular to a catering system based on Internet of things search.
Background
With the vigorous development of the online catering takeout industry, the online catering takeout industry gradually becomes the rigid demand of people and is popular with more and more users. At present, the scale of online catering takeaway users in China breaks through 3 hundred million people. This means that out of every five people, at least one person wins the take-out. The existing online take-out platform is represented by how hungry, American group take-out and Baidu take-out, and the food ordering operation mode is as follows: the user selects a heart instrument shop and dishes on the internet or the app according to the sales volume and the distance, generates an order after filling related data, and waits for the response of the shop after paying the order of the dishes. The merchant receives the dish order, and issues a distribution task list after making the take-out dish according to the order. And the distributor receives the distribution task list, and distributes according to the distribution address after the merchant obtains the take-out dishes.
Although the existing online catering mode provides convenience for ordering food for users, the distribution address is single, and the existing online catering mode is mainly centralized at home or work units. When the user is far away from home or the work unit, the user often gives up selecting online meal ordering because the user cannot find a proper meal place. And the merchants on the existing online catering platform are numerous, the user mainly depends on the description of characters and pictures of the merchants on the dishes when selecting the dishes, the user cannot know the processing process of the dishes, and an effective dish quality monitoring mechanism is lacked.
