Wireless sensor networks are data-centric, in which data management and representation is a crucial issue. In this paper, sensor networks deployed to monitor wetland and underwater environment by multi-hop networks are equipped with the Network-centered Software Platform to visualize the data and topology. Our visualization software platform adopts threelayer model as architecture. The three-layer model equips our visualization software platform with favorable flexibility, scalability, better security, higher reusability and good fault tolerance. The technologies involved in this paper include serial communication, database management and data visualization which is to visualize the data gathered by wireless sensor networks. The database can be accessed by both local users and remote users through Internet. Of course the users must have an authority to know the conditions of wireless sensor networks. Practical experiments have illustrated that our visualization software platform can get data from the wireless sensor networks and provide real time and historical information for users. It is convenient and efficient.

This paper describes the implementation of the temperature control system for sintering shaft furnace. In order to solve the problems caused by pure time-delay and non-linearity, an intelligent serial temperature control system is introduced in this paper, where the fuzzy controller is used in the main control loop and the fuzzy neural network PID controller is adopted in auxiliary loop. Simulation results show that this system is stable and has stronger anti-interference capability. Finally, the hardware and software implementation methods for the firebox temperature control system are introduced. The real production results demonstrate that production requirements are met and better control effects are obtained. The aim of energy saving and consumption reduction and quality improvement is achieved.
