Принадлежит:

The invention relates to a safety explosion proof illuminator applicable to an inflammable, explosive or damp place. Said device includes a cable conductor, a cut out switch, a mutual inductance type transformer, a flame-proof luminaire and a fixed or movable luminaire support. An explosion-proof, water proof, dust proof and anticorrosive multifunctional luminaire is adopted for the light fitting. The process is that power cord of 380V or 220V voltage is switched in input wire of the mutual inductance type transformer, and by output line of the mutual inductance type transformer, the input voltage is changed into safety voltage, namely 36V, 24V and 12V, then the output is connected to the flameproof lamp. Said illuminator can put an end to electric shock, explosion and fire accident occurrence.

The invention discloses an automatically opening and closing elevator based on infrared sensor detection. The automatically opening and closing elevator comprises a stop floor carriage door and a stop control panel arranged at each floor, and a carriage which is arranged inside an elevator shaft and can move up and down, and a central processor for controlling the ascending and descending states of the carriage. The stop floor control panel is provided with an infrared sensor for detecting whether there are people around the stop floor carriage door. The central processor is provided with a processing module for receiving detection signals from the infrared sensor and judging whether a stop instruction inputted from the stop floor control panel is valid based on the detection signals. When the infrared sensor outputs the detection signal indicating that there is nobody nearby, the processing module of the central processor immediately cancels the stop instruction inputted by the stop control ...
