摘要：【中文】本发明涉及用于监测和控制具有游动卡瓦和固定卡瓦的不压井起下作业设备的系统和方法。位置传感器与卡瓦相联，用于检测卡瓦的打开和闭合位置。载荷传感器与卡瓦相联，用于监测卡瓦的载荷状态。当管柱载荷从一组卡瓦转移到另一组卡瓦时，控制系统接收来自传感器的输入信号，并在释放相对的卡瓦组或允许相对的卡瓦组释放之前确认游动卡瓦或固定卡瓦是负荷的。 【EN】The present invention relates to a system and method for monitoring and controlling snubbing equipment having traveling slips and fixed slips. Position sensors are associated with the slips for detecting open and closed positions of the slips. Load sensors are associated with the slips for monitoring the load state of the slips. When the string load is transferred from one set of slips to another, the control system receives input signals from the sensors and confirms that either the traveling slips or the fixed slips are loaded before releasing or allowing the opposite set of slips to release.
