计轴设备是检查线路、道岔、平面交叉和道口区段占用或空闲状态的安全设备,其作用与轨道电路等效。计轴又称微机计轴,是铁路两端车站设备,利用安装在钢轨的闭环传感器监督列车车轮对经过数,经过设在室内的微机系统与门检测后将本站的轮对数利用半自动设备发送至对方站,列车到达对方站后,对方站收到轮对数与发车站的相同时,自动开通区间。是1种能检测通过车轮的铁路信号设备,它能够取代许多的普通轨道电路。
The axle counting equipment is a safety device that checks the occupancy or idle state of lines, turnouts, plane intersections and crossing sections, and its effect is equivalent to that of the track circuit. Axis, also known as computer axis, is a railroad station at both ends of the station equipment, the use of rail mounted on the closed-loop sensors to monitor the number of passing train wheel, after the indoor computer system in the door and the detection of the site after the use of semi-automatic wheel equipment Sent to the other station, the train arrived at the other station, the other station received the same number of wheels and departure station, automatically open interval. It is a railway signaling device that can detect the passage of wheels and it can replace many common rail circuits.
