Electronic elevator guard device and method for monitoring a set of integrity states of a plurality of elevator features

摘要

An electronic elevator guard device (3) for monitoring a set of integrity states of a plurality of elevator features is proposed. The electronic elevator guard device (3) comprises at least one sensor (19) installed in an elevator (1) and configured for monitoring at least a first one of the integrity states of an elevator feature and generating a first monitoring signal based on a sensed current status of the first integrity state. Furthermore, the electronic elevator guard device (3) comprises a questioning device (21) comprising or communicating with a human-machine interface (23) and configured for asking predetermined questions to a consulted person and for receiving the person's answers via the human-machine interface (23), the questions relating to at least a second one of the integrity states of an elevator feature, and generating a second monitoring signal based on at least one answer. Finally, the electronic elevator guard device (3) comprises an evaluation device (35) configured for generating an overall monitoring signal based on the first and second monitoring signals which may be sent to a remote recipient (39) via a communication device (37). Using the electronic elevator guard device (3), integrity states of a plurality of elevator features may be monitored partly automatically using sensors (19) and partly using the assistance of consulted persons answering to questions issued by the questioning device (21). Overall, using such guard device (3), repeated monitoring of the elevator (1) by specific human elevator guard may be dispensable such that significant efforts and costs may be saved.
