The Design And Implementation Of Shared Umbrella System Based On IoT

With the large-scale popularization of the mobile Internet,many innovative ideas have been developed with the help of the Internet,and the shared economy is one of them.The concept of shared economy has been integrated into different industries by many enterprises at home and abroad.For example,Uber and Airbnb have adopted shared models in the taxi industry and hotel industry respectively.OFO and Mobike are engaged in shared bicycles and large-scale public bicycles are put into cities.The establishment and spread of the shared economy industry are inseparable from the development of the Io T technology.With the support of the Io T technology,we can connect shared services or goods with the Internet,operate and spread them through the Internet,and increase the degree of informatization and automation.At present,the operation model of shared economy products has been relatively mature.Products such as shared cars and shared power banks have continuously poured into the market,with both opportunities and challenges.Among them,shared umbrella is developing vigorously with the concept of green travel and optimal utilization of resources.On this basis,this article shows a shared umbrella system,which meets the temporary needs of users in case of sudden rain.This improves the comfort of users' lives and increases the utilization of social resources.This system can be divided into umbrella management module,umbrella scheduling and rental configuration module,umbrella service module,order module and payment module.With the help of RFID technology and MQTT protocol technology of the Io T,the administrator can take the umbrella on and off the rack in the umbrella scheduling module,and automatically update the offline umbrella scheduling results to the system.Users can rent and return the shared umbrella in the umbrella service module.The Io T device of the umbrella rack will recognize the unique id of the umbrella and upload it to the system,and the system will generate the umbrella rental and return records.Through the Io T technology,the software system can be connected with each shared umbrella.In addition,the umbrella management module is responsible for the registration of umbrella rack and umbrella,the abandonment of umbrella and other functions of the administrator account.The rental configuration module is responsible for the function of rent policy configuration.The order module is responsible for generating the user's umbrella borrowing order,calculating the order price,and providing the implementation of functional interfaces such as querying and counting orders.The payment module is responsible for interfacing with third-party payment platforms and deducting the cost of renting the umbrella by the user.The system uses Spring Boot as the back-end service framework,and achieves service registration and discovery by Consul middleware.Distributed service invocation and load balancing are achieved by the Spring Cloud Feign framework.Hot data is cached through the Redis cache system to improve access speed and reduce the pressure on the database.The system communicates with the Io T device on the umbrella rack through the MQTT protocol,and stores the data through My SQL.The system was deployed and launched on September 27,2019,and is currently in actual use.In the past six months,the number of users of the system has gradually increased,and its influence has steadily increased.
