Description

A catering cloud platform system

【Technical field】

The invention relates to a cloud platform system, in particular to a catering cloud platform system.

【Background technique】

Most of the existing catering management systems use a stand-alone version, which cannot realize multi-user service access, and has shortcomings such as redundant construction of system resources and large differences in standards between different systems.

The few existing online versions of the catering management system are only used by a certain catering group. Most of the systems have not realized the transformation of the demand for catering informatization into a standardized platform service, so the system architecture is quite different from the present invention.

With the wide spread of the Internet and the emergence of various Internet services, the original solution to a certain information application will gradually bid farewell to the stand-alone software model based on individual terminals, and move to the Internet-based platform service model (ie, SaaS platform service mode) change. The SaaS (English full name: Software-as-a-Service, software as a service) is a mode of providing software through the Internet. Users do not need to purchase software, but rent Web-based software from providers to manage business activities. . With the promotion of SaaS platform services, a good interface is needed between the platform and users. During our development of the SaaS cloud service platform for the catering industry, we found the following requirements for the interface of the SaaS platform for the catering industry: 1) The system performance requirements are high, and it needs to be able to support multiple tasks and place orders during peak business periods to avoid data accumulation. 2) The system has high requirements for flexibility, and it is necessary to add user-specific requirements on the premise of ensuring that the system runs 7*24 hours. 3) The system compatibility requirements are high, and a new device solution is added under the premise of maximally reusing the customer's existing equipment. However, the interface of the existing SaaS platform service mode cannot meet the above requirements. The device mentioned in the present invention is a wireless POS printing device or a wired POS printing device or a short message gateway

The few existing systems that have proposed the concept of catering cloud only briefly describe the overall catering cloud system architecture, and few of them have realized it. For the existing catering cloud system that has been implemented, it can be seen that its interfaces and connected devices are not flexible, and most of the connected devices are dedicated devices. At the same time, part of the business logic is integrated on the connected device. If the core business logic is not separated from the connected devices, the following problems will occur:

1. The connected device carries the business logic. When changes in user requirements affect the business logic on the device, the application on the device also needs to be modified;

2. For merchants, while accepting the SaaS model, they hope to obtain more professional services at the lowest cost. However, the use of special equipment is not compatible with the existing equipment of the merchant, and it also causes a waste of social resources;

3. The business logic is carried on the device. When the catering cloud system is widely used and the devices connected to the catering cloud system reach a certain scale, the catering cloud system processes the business logic from the connected devices. More consideration needs to be taken in terms of performance, for example , when the upper limit of system performance is reached, and the system cannot be flexibly expanded according to the scale of the device, the system performance will drop sharply, causing problems such as unstable system operation.

【Content of invention】

The technical problem to be solved by the present invention is to provide a catering cloud platform system, which separates business logic from equipment, makes the system more stable, and the interface unit is compatible with various equipment, and has good scalability.
