由哈尔滨铁路局研制成功的JWJ—C型微机计轴设备是一种新型的实时检查所防护区段列车及车辆占用或空闲状态的安全设备,它可与64半自动闭塞相结合,实现区间状态的自动检查和列车完整到达后的自动解除闭塞,不仅能保证行车安全,还可提高运输效率。 1 关键技术 1.1 轨道传感器 采用有源电磁传感器,具有强度高、密封绝缘性好,其应用已达到无维修、少维护的要求。传感器采用高频率,抗干扰能力强,具有完全鉴相功能,相位变化不小于160°,并可加、减轴计数,保证检测准确无误。
The JWJ-C microcomputer axis counting device developed by Harbin Railway Bureau is a new type of safety device that checks in real time the occupied or idle state of trains and vehicles in the protected section. It can be combined with the 64 semi-automatic blockade to realize the state of interval Automatically check and automatically lift the complete arrival of the train after the block, not only to ensure traffic safety, but also improve transport efficiency. A key technology 1.1 Orbital sensors using active electromagnetic sensors, with high strength, good sealing insulation, its application has reached no maintenance, less maintenance requirements. Sensor with high frequency, anti-interference ability, with a full phase-detection function, the phase change of not less than 160 °, and plus and minus axis count to ensure that the test is accurate.
