[Internet of Things] Cloud cartoon campus consumption system

Analysis of the status quo of the campus consumption system:

At present, most campus canteens use the old-style consumption system. For the old-style consumption system, there are many problems. The specific problems are as follows:

1. Recharge needs to line up, and the efficiency is low: most people are used to recharge before dinner, so the people who need to recharge before dinner are more concentrated, and recharge often has to wait in line.

2. Recharge is prone to errors and counterfeit currency: many of the charging staff are part-time internal staff in the canteen, not professional cashiers. Large amounts of cash and professional repetitive work are more prone to errors, causing inconvenience to canteen managers and customers.

3. Large workload of account checking: It is necessary to check with various cafeterias every day. The workload is large. Sometimes checking once a week is relatively risky. The headquarters cannot truthfully understand the recharge status of subordinate cafeterias.

In response to these problems, Dilsey Technology has developed a cloud cartoon campus consumption system, combined with advanced cloud Internet technology to solve various problems in the traditional campus canteen consumption system, and help contractors manage the canteen scientifically.

Detailed introduction of  cloud cartoon campus consumption system:

We will use Ali's cloud server to build a  cloud cartoon campus consumption system. The entire system is very simple to set up. The cloud consumption system does not need to set up a recharge machine. You only need to perform the recharge operation on the WeChat end, and then swipe the card on the transfer machine to complete the recharge process.

          The figure below is the topology diagram of the  cloud cartoon campus consumption syste

The background can query the daily recharge details and daily recharge summary, which facilitates the verification of the recharge status of the headquarters administrator system and WeChat transfer records to ensure data consistency. The following picture is a schematic diagram of the school backstage management system:

The all-in-one card management is implemented for consumption places such as canteens, convenience stores, and dormitory areas in the school, and all consumption data can be integrated into the Dilsey cloud system for unified management and query. The data is stored in the cloud in real time, and there is no error. This is the incomparable superiority of the past one-card model.

The mobile phone user interface mainly includes several major functions: registration, loss report, recharge, consumption notification, streaming, and campus micro-official website. The user interface diagram is shown in the following figure:：

The WeChat recharge process of  cloud cartoon campus consumption system is shown in the following figure: 

Description of the recharge process: The system is through the WeChat payment system. After the payment is successful, the student takes the card to the transfer machine and swipes the card to complete the self-recharge system. The manual operation of recharging is simplified, thereby improving work efficiency, reducing the problem of reconciliation of cash payment, and greatly improving the internal management level of the school. WeChat recharge mode, after users follow the  official account, bind their IC card number to enter the recharge mode.

Three advantages of cloud cartoon campus consumption system:

1. Mobile application system: Mobile applications have become a trend, and mobile payment is more convenient for employees to recharge; it improves efficiency for parents or students to recharge by themselves, without manual operation by personnel, and recharge without queuing.

2. Security of funds: The WeChat system automatically transfers the recharge amount of the previous day to the school account, and the headquarter financial staff only needs to check the account; avoid counterfeit currency and cash statistics errors, and reduce many intermediate links through automatic statistics and automatic transfers through the system , The security of funds is guaranteed; especially for chain catering service companies, fund security and management are particularly important, and fund security management is fundamentally solved through self-service reduction of intermediate links.

3. System data security: The dual database mode is adopted. There is a consumer database inside the school, and a database is connected to the external network and WeChat. Both databases ensure the safety and accuracy of data.

The entire configuration of the cloud cartoon campus consumption system project only needs to be:

1. Cloud platform consumer system

2. Consumer terminal

3. Transfer machine

4. WeChat public account
