The utility model discloses a clearance obstacle detection trigger device based on solid state relay, including the power, three time relay J1, J2, J3, two solid state relay J4, J5, ten switch K1~K10, four resistance R1~R4 and two diode D1, D2, time relay J1, J2, six terminals of J3, solid state relay J4, four terminals of J5, all sliding door close the lock after death, and the time relay J1 action will trigger the instruction and feed back to the laser alarm host computer, and the laser alarm host computer begins to start to be surveyed, when laser alarm host detect arrived the barrier that exists in the clearance between train and the platform, feedback signal to time relay J2 and time relay J3, switch board terminal received the signal, and the control train can't normally sail out of the platform. The utility model discloses can effectual detection train and the platform between whether have the barrier in the clearance, can reduce safety loop to the wrong report of barrier or fail to report. 本实用新型公开了种基于
