With the increase of the population density, High-rise buildings become more and more popular. Then people use tower crane more than before. And there are more accidents happened. So an effective system of safety monitoring should be designed as soon as possible. This paper as part of the project of tower crane safety monitoring, researches two parts of it: remote data transmission and the management of the data. The research and the design of the system are as follows:This paper gives a solution of data transmission using GPRS that suitable for tower crane. And it uses internet communication technology, database technology, web development technology to realize an efficient, safe transmission and reasonable, effective, convenient management.First, it gives the principle and characteristics of GPRS transmission, and develops three types of network mode.Second, it develops reasonable software and hardware design according to the demand of the transmission terminal. In the hardware part, it gives communication circuit, SIM card circuit, conversion circuit, power circuit, crystal circuit and scanning circuit. In the software part, it uses GPRS module initialization, dial-up, establish PPP link, Socket communication to complete the transmission of the tower crane data.Third, it uses .NET technology to develop the website design, in order to release the information the tower crane. And the database is designed by SQL Server, data link is designed by ADO.NET, page design is developed by CSS, master page and navigation. Also, it gives detailed design for login, data management, tower crane management and user management.Fourth, The disadvantages and extensions of the system are presented.
