Abstract (en)
The invention relates to a safety control system for an elevator, escalator or moving walkway, comprising a central control unit (4) and at least one electronic safety node (1, 2, 6) communicated with one another by means of a secure communication bus (5). Each electronic safety node (1, 2, 6) is functionally associated with at least one safety switch (1', 2', 6'), which are connected in series forming a safety chain (3). The electronic safety nodes transmit to one another and to the central control unit information relating to the state of at least one safety switch associated with a node, such that each safety node controls its safety switch depending on the information received from another safety node. The proposed control system can be easily scaled and allows reducing installation wiring for the purpose of reducing installation costs and facilitating the assembly thereof.
