目前,冶金矿山井下的自动风门,常因控制方法不当造成失控和误动作,而被弃置不用。为探讨一种较为可靠的控制方法,我们根据矿井有轨运输的特点,研制了一种无触点控制的感应式控制器,经实验室和现场试验后,已由武汉市青菱除尘设备厂试制成功,并在大冶有色金属公司铜录山矿自动风门控制中应用。一、原理无触点感应式控制器的基本原理是利用 At present, the automatic door of the mine underground mine, often due to improper control methods caused by loss of control and misoperation, and was abandoned without. In order to explore a more reliable control method, we developed a non-contact control of the inductive controller according to the characteristics of mine rail transport. After laboratory and field test, it has been constructed by Wuhan Qingling Dedusting Equipment Factory Trial successful, and Daye Nonferrous Metals Tongluoshan mine automatic throttle control applications. First, the principle Non-contact sensor-based controller is the use of the basic principle
