The Vertical Transportation-Maintenance Management System (VTMMS) invention described herein is directed towards an automated system and method for monitoring, management, and maintenance of transportation equipment, including but not limited to escalators, elevators, moving walkways, baggage carousels, revolving doors, and automated doors. The system and method is also adaptable to heating, ventilation, and air conditioning units and other building equipment. The system and method collects data from the monitored equipment and preserves data that is related to equipment alarms, faults, failures, and maintenance requirements and activities as determined by monitoring software.

In a method and system for controlling a revolving door that has a plurality of chambers defined by wings of a revolver, at least one imaging sensor is provided for acquiring images of a first area where the plurality of chambers rotatably pass by or through. A drive causes the revolver to rotate in a first direction from a first position where a user can enter a first chamber via the first opening. Images are acquired by the one imaging sensor and signals are acquired from a position sensor that is operative for outputting signals indicative of the angular position of the revolver. Based on the signals acquired from the position sensor, each imaging sensor or its output is disabled and / or each image acquired by each imaging sensor is ignored when each door wing is in field-of-view of the imaging sensor.

The invention relates to the field of revolving doors, in particular to a revolving door capable of conveniently removing dust and limitable in position. The revolving door comprises a protecting structure, a revolving structure, a position limiting structure, a mounting structure, a holding structure, a water spraying structure and a dust removal structure. The rotating structure can synchronously drive the water spraying structure to work while working; through the operation of the water spraying structure, watering maintenance work can be performed on a bonsai on the holding structure withwater in the holding structure; not only can the bonsai on the holding structure be conveniently watered, but also water resources can be recycled, and thereby, the goal of saving the water resourcesis achieved; by installing the mounting structure on the revolving structure, the aesthetic property can be enhanced, and the bonsai can also be prevented from artificially damaged; the mounting structure and the revolving structure can be rapidly fixed to facilitate installation and removal of the mounting structure; the rotating structure can synchronously drive the dust removal structure to work while working; and dust on the surface of a base can be swept through the operation of the dust removal structure.

A partition configured to be positioned within an aircraft. The partition includes a first divider assembly that includes a first wall portion having a first jamb member secured to an inboard surface thereof and a first door hingedly connected to the first jamb member. The first jamb member includes first lighting that illuminates the first door, and the first door is movable between a stowed position and a deployed position. The partition also includes a second divider assembly that includes a second wall portion having a second jamb member secured to an inboard surface thereof and a second door hingedly connected to the second jamb member. The second jamb member includes second lighting that illuminates the second door, and the second door is movable between a stowed position and a deployed position. The second door is spaced apart from the first door.

The invention discloses a rotary automatic door which comprises a fixed door leaf, a rotary door leaf, a driving device, a detecting device and a control device, wherein the driving device is used for driving the rotary door leaf to rotate, the detecting device is used for detecting the relative position of the rotary door leaf to the fixed door leaf, and the control device is connected with the detecting device and used for controlling the driving device to speed up, slow down or keep a uniform speed in accordance with the position of the front end of the rotary door leaf. The invention further discloses an operation method of the rotary automatic door. According to the rotary automatic door and the operation method of the rotary automatic door, the speed of the rotary door leaf of the rotary automatic door through a hazardous area is actively reduced, so that people in the hazardous area have enough time to move forward or backward, thereby greatly reducing the probability that the people are clamped by the rotary door leaf. When pedestrians or objects are detected by any danger sensor, the rotary door leaf can stop within a short braking distance, thereby reducing the impact force on the pedestrians or the objects, hurts to the pedestrians are minimized, and the pedestrians or the objects are guaranteed to exit in time.

A reversible door assembly is provided which allows for easy changing of a door swing direction without the need for any additional swing change kit and without the need for rotation of the door. The present embodiments provide a frame which utilizes removable pocket hinge elements which may be moved from one side of the frame to the other side in order to easily change the door swing direction.

A security revolving door assembly including a revolving door, a controlling unit and a LIDAR sensor. The LIDAR sensor is appropriately disposed in the top or canopy of the revolving door and advantageously directed downwardly into the passage space of the revolving door. In particular, a first LIDAR sensor is centrally disposed in a first quadrant of the canopy, and a second LIDAR sensor is centrally disposed in a third quadrant of the canopy.

The invention provides an automatic revolving door resistance stopping system and resistance stopping method. The automatic revolving door resistance stopping system comprises a motor for driving revolving door leaves to operate and a controller, a motor main shaft is provided with a revolving encoder for detecting the revolving speed of the revolving door leaves, the revolving encoder is connected with a counter, and the controller receives the pulse number of the counter and controls the motor to operate. When the revolving door leaves are hindered, the revolving encoder detects that the revolving speed is reduced, and the controller controls the motor to stop revolving or revolve reversely. The automatic revolving door resistance stopping system can be installed on a revolving door of any type, installation is simple, and extra equipment does not need to be added to the revolving door. In combination with the above resistance stopping method, the automatic revolving door resistance stopping system does not have a blind area, and recognition can be achieved as long as the revolving door leaves bear resistance. The system is good in flexibility and adjustable in sensitivity, a man-machine platform is utilized, the flexibility can be adjusted just by increasing the line number of the encoder, and the system is quite convenient to use. The resistance stopping method is sensitive in reaction and is high in recognition speed and reaction speed compared with an electric current detection method, and squeezing of pedestrians is eliminated timely.
