Electronic elevator guard device and method for monitoring a set of integrity states of a plurality of elevator features
An electronic elevator guard device that monitors a set of integrity states of a plurality of elevator features includes at least one sensor in an elevator and configured for monitoring at least a first of the integrity states and generating a first monitoring signal based on a sensed current status of the first integrity state. The guard device includes a questioning device having or communicating with a human-machine interface and configured for asking predetermined questions to a consulted person and for receiving the person's answers via the human-machine interface, the questions relating to at least a second of the integrity states, and generating a second monitoring signal based on at least one answer. The guard device includes an evaluation device configured for generating an overall monitoring signal based on the first and second monitoring signals and sending the overall signal to a remote recipient via a communication device. |
