Abstract
Elevator safety and safety related information needs to be sent reliably to safety controlling systems. Existing elevator communication devices may be used for transmitting this information by processing the received safety and safety related information and processing it before sending it over the communication bus from the elevator car or floor equipment to the controlling devices. A separate communication unit may be used for receiving and processing safety and safety related data packets before they are transmitted over a common bus used for safety and safety non-critical submission.
Claims20
An apparatus comprising:
- a communication bus controlled by a respective communication microcontroller;
- at least one connection configured to connect safety non-critical elevator components;
- and
- at least one microcontroller configured to communicate with at least one safety critical elevator component, wherein at least one of microcontroller of said at least one microcontroller is coupled with said communication microcontroller.
A communication method for an elevator system, wherein said method is performed in a communication apparatus, the method comprising:
- controlling a communication bus by a respective communication microcontroller;
- receiving safety non-critical communication data packets from elevator components;
- receiving safety critical communication data packets from elevator components;
- and
- transmitting said data packets to a communication bus.
