A detecting apparatus includes a detecting carrier and a detecting device. The detecting carrier can be moved into a charging frame or anyone of storing frames of a stock room. The detecting device is installed in the detecting carrier and includes a power module and a detecting module. The detecting module is configured to detect environment information corresponding in position to the detecting carrier. The power module is configured to supply power for operating the detecting apparatus. When the detecting carrier is arranged in the charging frame, the power module is spaced away from the charging frame and is charged without contacting the charging frame.

A detecting apparatus includes a detecting carrier and a detecting device. The carrier can be moved into a charging frame or anyone of storing frames of a stock room. The detecting device is installed in the detecting carrier and includes a power module, a detecting module, and a wireless communication module. The wireless communication module can emit an electricity signal according to the power module. The detecting apparatus is selectively operable in a detecting mode and a charging mode. When the detecting apparatus is in the detecting mode, the detecting carrier randomly enters into one of the storing frames, so that the detecting module is operated to detect surroundings. When the detecting apparatus is in the charging mode, the detecting carrier enters into the charging frame, so that the power module is charged.
