[Abstract]:With the upgrading of satellite electronic system, integrated modularization system has become the development trend of satellite electronic system. In order to realize the high efficiency and high reliability communication between the modules of the measurement and control equipment in the spaceborne electronic system, In this paper, a backplane bus is developed for satellite measurement and control equipment. The bus not only has the function of high reliability data transmission, but also integrates the functions of data acquisition and instruction distribution into the remote terminal of the bus. The development of the backplane bus will provide a new system solution for satellite TT & C equipment. Based on the investigation of various kinds of buses and the actual engineering requirements of spaceborne measurement and control equipment, a new design scheme of backplane bus for spaceborne measurement and control equipment is put forward in this paper, and the bus form of the backplane bus is introduced in detail. On the basis of the investigation of the integrated circuit development process, the development of the bus interface and the measurement and control special integrated circuit in the remote measurement and control terminal based on the backplane bus is completed. The FPGA prototype development process of bus interface and measurement and control ASIC is described, and the design of each functional module is introduced in detail, and then the chip test platform of bus interface and measurement and control ASIC is designed. At the end of the paper, the paper summarizes the work done in this paper, and puts forward the improvement goal in view of the shortcomings of the design. The test and experimental results show that the function of bus interface and measurement and control ASIC is normal, the performance basically meets the design requirements, the communication function of backplane bus of spaceborne electronic equipment is normal, and the signal waveform measured on the bus is ideal. The feasibility of backplane bus is verified.
