Design and implementation of general timing monitored control system based on GPSDONG Jian-li, ZHOU Dan Department of Computer Science, Huaihai Institute of Technology, Lianyungang 222005, ChinaAbstract:Based on timing high precision requirement for many application fields and GPS timing is provided with the advantages of high precision, anti-disturbance, real time and so on. The principle, method and mechanism of the timing monitored control system based on GPS are analyzed and discussed. And then a general timing control system with GPS for all application fields as electric power, telecom, communication and so on is designed and implemented. Such as design ideas, implementation methods and development technologies about this practical GPS timing system will be widely applied and referenced in correlation fields.[著者文摘]
