The Bluetooth Wireless Distributed Monitoring System

This paper presents the architectrue and the implementing method of the bluetooth wireless distributed monitoring system. The main function of this system is adopting bluetooth technology to real-time monitor the security situation of the special equipments and the valuables in these departments and systems, such as museum, bank, security and management for infrastructure, etc. So it reaches the expectant goals, such as guaranteeing the safe operation of the special equipment and security custody of the valuables, improving the efficiency of safe running and custodying, reducing personnel to dispose, realizing scientific management.This paper discusses and researches some detailed issues about the bluetooth wireless distributed monitoring system . The main research contents and consults in this paper are as follows:(l)Presenting the overall scheme of the bluetooth wireless distributed monitoring system, including the software and hardware development of Monitoring Center (MC) and the conceptual design of two parts, Local Terminal Unit (LTU) and State Monitoring Unit(SMU).(2)Adopting object-oriented method and multithreading technique in the development of MC. It is characteristic of real-time processing,which realizes high safe reliability, good expandability and friendly man-machine interface.(3)Implementing the serial communication between the MC and LTU. Putting forward two rules for software flow control and data transmission, as well as implementing the design of the structures for ask frame, respond frame, order frame and data frame.(4)Developing a multimedia alarm system based on sound and characters for the MC.(5)Developing the software to manage the monitoring datum information for the MC by adopting ASP(Active Server Pages) technology in order to implement long-range management and control of the monitoring datuminformation for the administrators.(6)Presenting a piece of thought that the system user's authority gradeses and an algorithm of encrypting for the system user's password.
