| Ventilator has developed for about one hundrand years. The control system develops from the initial simple mechanical mode to multifunctional electronical one later, and then comes to now when computer and intelligent control technology are widely used. It leads to great extension in ventilation mode, function design and application fields. Household ventilator is effective in treating snore and OSAHS (Obstructive Sleep Apnea Hypopnea Syndrome), and it is gradually becoming the doctors' main recommendation to treat patients, and have been widely recognized by patients. As the growth of market and customer volume, ventilator manufacturers and dealers are facing more and more managing stress about user information and used data. Under the current rapid development trend of the Internet, smart phone and mobile Internet, home ventilator manufacturers vigorously improve functions and expand markets. However they don't pay enough attention to the development of online services, and it dramatically reduces the efficiency of agents' providing services and users' access to professional services.The ventilator online service system is designed and implemented in this paper, and it is convenient for agents to manage users' information and data. Agents can receive and analyse users'used datas online, and create detail reports for users in system. Ventilator users can easily upload datas and view reports at any time via the system. The system allows users to access online services from the time and space constraints, and improves the efficiency.Ventilator online service system consists of the following modules:database system, Web server, data management system and Android mobile phone client. Database system is built in MySQL which is an open source database system. Database is used to store and manage the users' personal information, the administrators' information and users' reports. Web server is achieved in Tomcat which are open source server. The server is used as a bridge for administrators and users to interact with the database. It could respond to requests from Android users with reports and personal information, and manage users' data at the same time. Ventilator data management system designed in B/S mode provides service for administrators. Administrators can manage users' information, download and analyse users' used data, and then establish reports for users. They can also view and search reports, and even modify the reports if necessary in browser. Android application provides service for ventilator users. Users obtain datas and upload them to server in application which has connected to ventilator via WiFi. The application can be used to check reports and recommendations for scientific and rational use of the ventilator to get professional guidance, anytime and anywhere possible.Finally, test the ventilator online service system with method of Black Box Testing. We test the response speed, concurrency, and stress testing for Web server. Interfaces and functions are tested for the ventilator data management system and Android application. The entire system stability and performance meet the system requirements and users' needs.Ventilator online service system with features of stable performance, low cost, fast deployment, and strong scalability, is suitable for small and medium ventilator enterprises or agents. The system is used to provide users with convenient and efficient online services, and improve work efficiency. |
