In this paper, the whole system is designed as two parts separated from the front and the back. The Android smartphone is used as the hardware platform to realize the information collection, and the centralized processing and persistent storage of the collected data is realized by building a server in the background. According to the characteristics of engineering quality and safety information and the needs of management personnel, mobile terminal technology and Internet of Things technology are applied, software platforms are developed, a mobile terminal-based engineering quality and safety information collection system is established, and practical engineering applications are combined. Strengthen the construction of quality supervision teams, improving professional quality, establishing a restrictive mechanism, etc., and put forward suggestions for improvement.
