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.
Claims15
An apparatus comprising:
- a first communication bus controlled by a first communication microcontroller;
- a second communication microcontroller configured to communicate with a second communication bus;
- 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 microcontroller of said at least one microcontroller is coupled with the first communication microcontroller, and
- wherein the apparatus is configured to:
- receive data packets received from said second communication bus,
- process the data packets received from said second communication bus, and
- transmit the processed data packets to said first communication bus.
A communication method for an elevator system, wherein said method is performed in a communication apparatus, the method comprising:
- controlling a first communication bus by a first communication microcontroller;
- receiving safety non-critical communication data packets from elevator components;
- receiving safety critical communication data packets from elevator components;
- transmitting said safety critical and safety non-critical communication data packets to a communication bus;
- communicating with a second communication bus;
- receiving data packets received from said second communication bus;
- processing the data packets received from said second communication bus;
- and
- transmitting processed data packets received from said second communication bus to said first communication bus.
