【摘要】 将开关设备在线状态监测技术与微电子技术相结合,提出了开关设备在线状态监测系统级专用芯片的设计方案。该芯片集采集、计量、通信、调度功能于一体,配以少量外围器件,就可以实时监测开关设备的温度、机械、绝缘等各项状态参数,而且可以与上位机通信。与以往使用单片机进行在线状态监测相比,专用芯片具有可靠性高、通用性强、成本低等优点,代表了在线监测技术未来发展的方向。通过用现场可编程门阵列(FPGA)进行硬件仿真,验证了该设计的正确性。更多还原

【Abstract】 By combining the on-line monitoring technology for switchgear in the past with the rapidly developing microelectronic techniques at present, this paper puts forward a design of a kind of system on chip for on-line monitoring. This chip has all the functions of sampling, measuring, alarming and communicating. Linked with a small amount of peripheral devices, it can not only monitor on-line the temperature, insulation and the mechanical of switchgears, but communicate with other computers. Compared with the on-line monitoring technology for MCU (microprogrammed control unit), the chip has more advantages, such as high reliability, flexibility and low cost and can represent the direction of the future development of on-line monitoring technology. The correctness of this design is validated through FPGA (field programmable gate array) simulation.更多还原
