在线路、桥梁、站场和大修工程施工中,列车要通过临时便线、便桥和改铺改移地段施工,需要对列车的行驶速度加以限制。这就迫切需要专门在施工地段测定列车实际行驶速度的仪器——“测速仪”,对列车速度加以监测、控制和约束,以防事故的发生。 锦州工程处科研室在有关部门的支援下,研制成功“双线列车自动测速记录仪”。 双线列车自动测速记录仪可以精确地测定
In the construction of the lines, bridges, stations and overhauls, the trains are to be constructed through temporary meridians, condos and rebuilt sections, which limit the speed of the trains. This urgently needs an instrument specifically for measuring the actual speed of trains in the construction site, a speedometer, which monitors, controls and restrains the train speed to prevent accidents. Engineering Department of Jinzhou Research Department in the relevant departments with the support of the successful development of “dual-track automatic speed recorder.” Two-track automatic train speed recorder can be accurately measured
