目前,矿用绞车中的罐笼深度指示有多种方法,例如光测法和自整角机测位法等,都能实时跟踪罐笼的位置,指示其位置,有些方案还设有过卷保护开关。本方案利用电容传感器作为罐笼位移的探测部件,配以变压器电桥作为测量电路,将电容量转换为电压量,然后送A/D转换,单片机处理,LED显示,读数直观,通用性强。 At present, there are several methods for indicating the depth of a cage in mine winches, such as the light measurement method and the self-alignment angle measurement method. All of them can track the position of the cage in real time and indicate the position of the cage. Some schemes also have an over-roll protection switch . The program uses the capacitance sensor as a cage displacement detection component, together with the transformer bridge as a measurement circuit, the capacitance is converted to voltage, and then sent to A / D conversion, SCM processing, LED display, intuitive readings, versatility.
