The use of optocouplers to improve passenger elevator safety

The article discusses the use of wireless technologies for monitoring the condition of elevators in high-rise buildings and the use of optocouplers for generating and transmitting alarm signals in the event of a power failure. It describes the distinctive features, promising areas of development and application of optocoupler technology, the classification of optocoupler product parameters, and the features of designing wireless networks for such systems, taking into account the characteristics of buildings. The analysis shows that the proposed autonomous system for alerting about elevator stoppages due to sudden power outages allows for the rapid rescue of people trapped in elevators, monitoring the technical condition of elevators, and preventing accidents, which is especially relevant for outdated elevators in Uzbekistan.
