ABSTRACT:
Analyzer apparatus for evaluating the performance of an elevator type transportation system that has a plurality of transport vehicles that serve a plurality of common stations includes a plurality of interface circuits each for connection to a system component to be monitored such as an elevator hall call button or a car relay, and each providing an output signal indicative of the current status of its monitored system component. Associated with each interface circuit is one or more event accumulator devices, and logic interconnects each interface circuit and its corresponding event accumulator device or devices. The analyzer also includes a signal generator for repetitively generating signals at periodic time intervals, and circuitry for applying each time interval signal to the logic for causing an accumulator device to accumulate event duration counts as a function of the monitored component current status signals from its interface circuit.
