China has made significant progress in the development of key sensing technologies such as wireless intelligent sensor network communication, micro sensors, sensor nodes, cluster points and application systems. From the "Symposium of Sensing Technology of the Chinese Academy of Sciences" held in Shanghai, it was learned that during the "10th Five-Year Plan" period, the Chinese Academy of Sciences organized nearly 20 research institutes in the whole hospital to carry out joint research, and in the basic research, proposed a series of algorithms and systems. In particular, the sensor network, the MESH (mesh network) sensor network, the disabled limited distributed task assignment, the blind source separation of the sensor network, the cooperative fusion, the target tracking, and the target positioning are randomly arranged. In terms of important sensor components, MEMS (Micro Electro Mechanical Systems) vibration sensors, MEMS acoustic sensors, MEMS infrared sensors, fiber optic sensors, and acoustic array sensors have been independently developed, and a series of miniaturized sensors based on MEMS sensors and composite multi-information detection have been formed. . At present, seven kinds of devices have clear application directions, and the two devices are supplied in batches, which has established the domestic leading position of the Chinese Academy of Sciences MEMS technology level. At the system level, five series of nine sensor network end machines and four series base stations were prototyped, and breakthroughs were made in low power consumption and miniaturization. A major breakthrough has been made in the research of private networks. The sensor network devices developed can be used to form various types of sensor networks, and the wireless interconnection of various wireless sensor networks with public networks and satellite networks has been successfully realized. At the same time, the core protocol chip of the wireless sensor network was developed.
