A non-contact control system includes a control circuit board, a Beacon Gateway, and a mobile electronic device with the original structure of the device to be controlled. The main feature is that when the application of the mobile electronic device is activated, the mobile electronic device displays a control screen for the user to click to control the actuating of the main body. Therefore, the user does not need to touch physical buttons and make a sound in the control operation, so direct contact and droplet infection can be avoided.

The present invention relates to a method for initiating a data connection between a central server and a control unit communicatively coupled to an elevator, escalator or autowalk. The method comprises: receiving a trigger signal from the central server, wherein the trigger signal is delivered with a service of a mobile communication network into which the control unit is communicatively coupled to; detecting if the trigger signal complies with at least one pre-defined requirement; and in response to a positive outcome of the detection initiating a data connection establishment from the control unit to the central server. The invention also relates to a control unit for an elevator, escalator or autowalk.

A building management robot includes a communication unit configured to recognize an identification device corresponding to a first divided space among at least one divided space in a building and acquire first identification information of the first divided space from the identification device, a camera configured to acquire image data including a position where the identification device is recognized, and a processor configured to recognize a user from the image data, confirm an authentication level of the first divided space of the recognized user from a database, and provide the user with a service based on the confirmed authentication level.

A system and method is presented for hands-free operation of elevator using a smart phone or like device to display one or more colours that are read by a colour-detection device mounted in an elevator cabin and at each elevator landing. Different colours can be displayed by the smart phone or like device and detected by the colour-detection device where different can represent different commands to operate the elevator.

A car safety supervising unit (SSU) for an elevator having an elevator car displaceable within an elevator shaft includes at least one sensor for sensing car-related parameters and outputting corresponding car-related signals, an I/O interface for inputting input signals into the car SSU and for outputting output signals to external devices and a signal processing unit for processing at least one of the car-related signals and the input signals and for generating the output signals. In an installation operation mode, the signal processing unit processes exclusively the car-related signals and generates the output signals based exclusively on the car-related signals whereby the car SSU accomplishes basic safety functions for safely operating the elevator with a limited number of available sensors. In a normal operation mode, the signal processing unit processes both the car-related signals and the input signals and generates the output signals based on both.

The present invention relates to a method and a system of commissioning elevator, and an elevator system. The method includes obtaining at least one operation data of at least one elevator door, comparing the operation data with corresponding criterion operation data, and determining whether a deviation between the operation data and the criterion operation data exceeds a pre-set range, and if so, triggering a control over at least one control end relevant to the operation of the elevator door to make a deviation between the operation data re-obtained and the criterion operation data fall within the pre-set range. The invention will increase the efficiency in elevator commissioning and remove the adverse effects on elevator operation caused by factors such as “Stack Effect”, and thereby ensure good working condition and high security of elevators.
