MDY—Ⅱ型遥控器系1980年开始研制,全部图纸和样机均送上海煤矿机械所防爆检验通过,1981年12月发给了下井试验的许可证。1982年3月～10月在湖南省谭家山煤矿和资江煤矿进行了井下工业性试验。用户反映:该机各项技术特性都达到了预定指标要求,工作性能良好。由于电路采用双频编码顺序制双 T 选频网路等措施:因而具有抗干扰能力强、信号动作可靠等优点,是较
MDY-Ⅱ-type remote control began to develop in 1980, all drawings and prototypes are sent to Shanghai Coal Mine Machinery Explosion-proof inspection passed, in December 1981 sent to the next test permit. 1982 March to October in Hunan Tanjia Shan Coal Mine and Zijiang Mine conducted a downhole industrial test. Users reflect: The aircraft technical characteristics have reached the predetermined target requirements, work well. As the circuit uses dual-band encoding sequence of dual-T frequency selection network and other measures: it has anti-interference ability, reliable signal action, etc., is more
