The invention relates to a medium-low speed maglev turnout switch control circuit, which is characterized in that an operation command is given through a signal system or a field operation control switch, when no fault signal is detected and a position signal is output, a given relay is pulled-in and self-locked, and meanwhile, a switch relay is also pulled-in; then an unlocking relay is pulled-in, a unlocking driving loop is connected, a lock pin mechanism starts unlocking operation, operation is stopped until the unlocking in-place limiting switch acts, an unlocking in-place signal is generated, and meanwhile the unlocking relay is disconnected; then the switch driving loop is switched on, a switch mechanism starts to operate in the given direction, operation is stopped until the switchin-place limiting switch acts, a switch in-place signal is generated, and meanwhile the switch relay is switched off; then the locking relay is pulled-in, a locking driving loop is connected, the lockpin mechanism starts to operate in a locking mode, operation is stopped until the locking in-place limiting switch acts, a locking in-place signal is generated, and meanwhile the locking relay is disconnected; at the moment, the system outputs a new position signal and disconnects the given relay.
本发明涉及一种中低速磁浮道岔转辙控制电路,通过信号系统或现场操作控制开关给定运转命令,检测到无故障信号并输出位置信号时,给定继电器吸合并自锁,同时转辙继电器也吸合;进而解锁继电器吸合,解锁驱动回路接通,锁销机构开始解锁运转,直到解锁到位限位开关动作后停止运转,生成解锁到位信号,同时断开解锁继电器;进而接通转辙驱动回路,转辙机构开始按给定方向运转,直到转辙到位限位开关动作后停止运转,生成转辙到位信号,同时断开转辙继电器;进而锁紧继电器吸合,锁紧驱动回路接通,锁销机构开始锁紧运转,直到锁紧到位限位开关动作后停止运转,生成锁紧到位信号,同时断开锁紧继电器;此时,系统输出新的位置信号,并断开给定继电器。
