The invention discloses an ultrasonic wave liquid level detection full-automatic drainage and flood drainage control system. An ultrasonic wave liquid level sensor acquires and outputs a liquid level height signal according to interval time between ultrasonic wave emission and receiving. A water pump control unit acquires the liquid level height signal and independently and correspondingly controls each water pump according to the liquid level height signal through each low-voltage relay so that each water pump is independently produced or quits running. By using the ultrasonic wave liquid level detection full-automatic drainage and flood drainage control system, multiple pumps are equally used; improved normal state protection and emergency response functions are provided; manual operation and intervention are reduced; and a potential safety hazard caused by a manual factor is avoided. 本发明公开了种超声波液位检测全自动排水排涝控制系统。所述超声波液位传感器根据发射和接收超声波之间的间隔时间获得并且输出液位高度信号。所述水泵控制单元获取上述液位高度信号，并且根据上述液位高度信号通过各个低压继电器相互独立地对应控制各个水泵，使得各个
