  • Patent number: 4765442
    Abstract: 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.
