The invention discloses an intelligent inspection and detection method for a coal conveying belt conveyor in a coal conveying bin area. The intelligent inspection and detection method comprises a set of single track, a mobile robot, a set of automatic rotating holder, a set of sound sensor, a set of gas detector and temperature and humidity sensor, four sets of autonomous charging stations, a set of field wireless communication deployment system and a background processing server. The problems that a traditional inspection system is low in integration and intelligence degree, and intelligent processing and judgment of various information on site, especially artificial intelligence detection of belt defects on site, are difficult to achieve are effectively avoided; subjectivity, hysteresis and possible accident omission caused by interpretation depending on monitoring personnel in traditional inspection are avoided, and heavy loss caused by breakage of the belt is avoided through belt defect detection.
