| Zusammenfassung: | The invention provides a satellite-borne miniaturized distributed temperature control driving single machine. The single machine comprises an FPGA control circuit, an AD conversion circuit, a thick film circuit, an RS422 communication circuit, a thermosensitive acquisition circuit, a power supply conversion circuit and a safety switch related control circuit. The distributed temperature control driving single machine selects a thick film circuit as an internal heater driving and power supply safety switch, and the thick film circuit has the characteristics of high integration level, high withstand voltage value and large single-path overcurrent, has the functions of overcurrent protection, current detection and switch state detection, can realize the safety control of a sub-control single machine on the heater, and ensures the product reliability. The invention provides an integrated, miniaturized, lightweight and extensible satellite-borne distributed temperature control driving single machine, and compared |
