The process of building environmental information perception can be constructed with wireless sensor network (WSN) expediently. A WSN based information acquisition system for building running environment is described in this paper. The CPU of host computer in the system is Loongson2F and wireless nodes in the system are implemented as Telsob nodes. Because the price of wireless node is low, the hardware cost of the desired system is decreased evidently and the security of the desired system is enhanced because the CPU of the host is native. With those features, the application scenario of the desired system is extended widely. To verify the suitability of the using of Collection Tree Protocol (CTP) in construction of the WSN in the desired information acquisition system, the performance of the CTP based WSN deployed in public building space for environment information acquiring are tested and solutions for some key problems in the construction and the maintenance of the CTP based WSN are given in this paper too.

During the 1990s, with the rapid development of science and technology, the human production and working mode or life-style have the huge transformation. In the sports field, researchers and teachers have the aid of modern science and technology resources to improve various teaching methods , which do help to master the technical action and improve the sports level. In the practical application, these teaching methods is more effectual than conventional method in sports skill learning. Use exploratory study method to develop a suitable and low-price underwater video acquisition system for daily swimming teaching, which is also easy to be operated. The system is with the aid of underwater surveillance cameras to realize the technology of underwater swimming action film and real-time looked, and through the acquisition card timely playback and slow play function to intuitive realistically restore underwater technical movement dynamic change process. This research use the teaching experimental method,mathematical statistics and comparative analysis and so on, the students make two sets of different teaching contrast experiments, verify the effect of the underwater video acquisition system. Underwater video acquisition system in swimming teaching application, change the teacher explain demonstration and strengthen the students single teaching mode, formed by means of image data timely feedback video feedback teaching method.
