⟡ Main research areas

Electronic measurement and bus control technology

1.   Research on intelligent IoT perception systems

Intelligent IoT serves smart cities, roads, and traffic and other fields, and it realizes the real-time monitoring and adjustment of physical parameters of key facilities and equipment through the establishment of the physical perception layer, network communication layer, and application layer. Examples of the team' research include: application of intelligent supervision system, intelligent IoT cold chain monitoring and control system, and intelligent gathering and transportation pipeline monitoring system, and so on to the asphalt pavement.

2.   Advanced bus control and measurement technology

Advanced bus technology is a practical system control and monitoring mean. It establishes a decision-making layer, control layer, and measurement layer in the system, and uses high-speed bus to achieve the communication among various systems and form an automatic feedback measurement system. Representative examples of the team are: maritime integrated monitoring and control system, electronic satellite load equipment bus controller, fire control bus control system, etc.

3.   Phase noise measurement technology

Phase noise is an important indicator of the performance of instruments and equipment, and phase noise measurement is of great significance in the research and development of radar and communication equipment. In the measurement and analysis and research field of signal source stability, the team has been funded by pre-research projects of the General Armaments Department during the 12th Five-Year Plan period, and general programs of NSFC
