The invention relates to a computer interlocking control three-phase alternating current turnout control circuit, and belongs to the technical field of rail transit signal control. A three-phase alternating-current turnout control circuit for computer interlocking control is characterized in that contacts of a 2DQJF are connected to a 3-4 coil excitation circuit, a turnout indication circuit and a turnout action circuit of a 1DQJ, and the circuit can enable the DBJ/FBJ to be excited and sucked up only when the 2DQJF and the 2DQJ are consistent in position state; meanwhile, the circuit prevents hidden dangers and risks caused by the fact that a 3-4 coil excitation circuit of the 1DQJ cannot be disconnected in time when the 2DQJF cannot normally switch poles for some reason in the turnout switching process in the prior art, and the circuit further controls relevant relay driving according to driving information of a turnout interface circuit of a computer interlocking system and gives relevant alarm information. Risks of wrong operation and false representation of the turnout caused by wrong construction, leak detection and repair and the like of signal personnel are prevented.
本申请涉及一种计算机联锁控制的三相交流道岔控制电路,属于轨道交通信号控制技术领域;一种计算机联锁控制的三相交流道岔控制电路,将2DQJF的接点接入了1DQJ的3‑4线圈励磁电路、道岔表示电路和道岔动作电路,该电路只有在2DQJF和2DQJ位置状态一致时才能使DBJ/FBJ励磁吸起,同时该电路防范了现有技术在道岔转换过程中2DQJF因故不能正常转极时1DQJ的3‑4线圈励磁电路无法被及时断开带来的隐患风险,该电路还根据计算机联锁系统道岔接口电路驱采信息对相关继电器驱动进行控制并给出相关报警信息,防范了信号人员因为错误施工、漏检漏修等原因带来的道岔错误动作和道岔假表示的风险。
