摘要:
A fail-safe power control apparatus for supplying power between an energy source (4) and the motor (5) of a transport system is provided. The power control apparatus comprises a power supply circuit (6), which comprises at least one converter (7, 8) containing change-over switches (32). The power control apparatus comprises a control arrangement (24) for controlling the converter change-over switches, a data transfer bus (10), at least two controllers (1, 2) adapted to communicate with each other, and a control arrangement (11) for controlling a first braking device, and possibly a control arrangement (43) for controlling a second braking device.

The invention relates to a method and to an apparatus for performing a rescue run with an elevator. In the method information is received from the sensors measuring the operation of the elevator about the points being measured with the sensors in question, one or more rescue run functions are selected on the basis of information received from the sensors, and also a rescue run, including the selected one or more rescue run functions, is performed.
摘要:
An elevator control system and method for efficient failure control of block operation with a local area network on the traveling cable and distributed electronic control circuits in the car and proximate to the respective floors with a remote microprocessor controller for each car. A local area network also provides communication with the corridor fixtures in a serial signal format of input and output signals. Each remote controller includes a microprocessor based computer circuit which normally communicates over a multicar-link with the other and also over the local area networks for car and hall calls. Each controller implements an adaptive time based block operation with the total building being serviced, despite partial or total failure of communication between the controllers and the corridor fixtures, which would otherwise degrade the bank operation sooner and more restrictively.

A passenger transport installation, e.g. an elevator or stairway, includes at least one drive motor, a conveying device, sensors and an installation controller. The installation controller is connected to at least one local bus node via a status bus, which bus node can receive status signals from an assigned sensor and transmit the same to the installation controller via the status bus to control the passenger transport installation depending on the status signals received. A servicing controller, as a replacement for at least one of the sensors, is connected to the local bus node that is assigned to the replaced sensor or to a centralized bus node for delivering simulated status signals that correspond to the status signals of the replaced sensor in a state that is selectable by the servicing controller.
摘要:
An elevator control apparatus and stored program system comprises an auxiliary control device together with a main control device in which a control program is stored. In the normal state, the main control device is used whereas in a fault of the main control device, the auxiliary control device is actuated to control an elevator upon detecting the fault.

A method and control device for monitoring travel movements of an elevator car utilize an electronic control device positioned at the car. Travel movements of the elevator car are travels, speeds or accelerations of the car. At least individual travel movements are subject to redundant detection for the purpose of monitoring. Either the travels or the speeds are redundantly detected and the accelerations singularly detected, or alternatively the accelerations are redundantly detected and the travels or the speeds are singularly detected, or preferably the travels or the speeds and the accelerations are redundantly detected. The electronic control device is preferably arranged at the support rollers of the elevator car.

An elevator control system and method for efficient failure control with a local area network on the traveling cable and distributed electronic control circuits in the car and proximate to the respective floors with a remote microprocessor controller for each car. A local area network communicates with the corridor fixtures in a serial signal format of input and output signals. Each remote controller includes a microprocessor based computer circuit which communicates over a multicar-link with the other and also over the local area networks for car and hall calls to implement an expanded control strategy with interactive program modes with least restrictive capability. This program interacts with programs for floor control strategy and bank control strategy for the elevator system to select the best car and the most efficient operation, despite failures which would otherwise degrade the bank operation sooner and more restrictively.
