The invention relates to a roller shutter door opening and closing detection device, a box body and a fire fighting truck. The roller shutter door opening and closing detection device comprises a non-contact type detection part arranged between a roller shutter door (5) and a door frame (6), and the non-contact type detection part is used for detecting the closing and opening state of the roller shutter door (5) relative to the door frame (6). According to the roller shutter door opening an closing device, the non-contact type detection part is arranged between the roller shutter door and the door frame, no physical collision occurs during the detection process, the closing and opening state of the roller shutter door and the door frame can be detected more reliably, the probability of detection errors is reduced, and the service life of the detection part can also be prolonged. The non-contact type detection part is small in size, and the probability that the detection part and objects placed in the box body collide to cause detection failure can be decreased.
