Abstract: With the rapid development of information construction, the wisdom mine platform has higher requirements for the capabilities of data interaction and integration in multi-source heterogeneous systems including personnel positioning system. The current personnel positioning system usually used closed architecture, which has many problems such as cumbersome development process, difficult data integration and inelastic expansion. In order to solve the problems, a framework of personnel positioning system adopting microservice architecture was proposed. This method introduced a storage technique of data categorization based on a time series database, designed a system architecture of soft bus, and realized a lightweight communication mechanism between different business and external heterogeneous systems. On the hosting platform, business application created by microservice and deployed by Docker image, which greatly improves the scalability and portability of the system.
