新型电子导管控制器研究

A New Type of Duplex Controller for Electronic Safety Tremies

提出了一种新型的电子导管控制器，可对塔带机、胎带机实行停机、报警和脱扣三级安全保护，用惠斯登电桥精确测量荷重，用最小二乘法处理数据．试验表明，所提出的电子导管控制器有较完善的容错措施和故障诊断功能，可对传感器进行理论率定，可靠性高、功能强且使用方便．

A new type of duplex controller for electronic safety tremies is proposed to protect tower cranes through conveyor shut off, warning horn and trunk release. Its weighing principle and data process by least square error method are described. This controller is characterized by high reliability, versatile functionality, easy convenience, good fault tolerant and fault diagnostic capabilities. Theoretical adjustment of load cells can also be performed with the controller.
