The invention discloses an intelligent automatic intensive storage system. The intelligent automatic intensive storage system comprises a fixing plate, a first transporting plate trailer, a conveyor,a workbench, a second transporting plate trailer and a goods shelf, the upper end of the fixing plate is fixedly provided with an acousto-optic alarm, moreover, the lower end of the fixing plate is provided with a supporting rod in a welded mode, the inner side of the supporting rod is fixedly provided with a smoke sensor, the front and back symmetrical positions of the upper end of the conveyor are fixedly provided with an infrared receiver and an infrared emitter correspondingly, the workbench is sequentially fixedly provided with a PLC and a counter from top to bottom, and the left end of the goods shelf is fixedly provided with a temperature and humidity sensor. According to the intelligent automatic intensive storage system, the acousto-optic alarm, the smoke sensor, the temperature and humidity sensor, the PLC, the infrared emitter, the infrared receiver and the counter are arranged, so that the problems that in the case of an existing intelligent automatic intensive storage system, an automatic counting function is not achieved, manual counting is time-consuming and effort-consuming, moreover, a smoke automatic reminding function and a temperature and humidity detecting function are not achieved, so that the practicability is not good are solved.
