    摘要： An elevator load bearing member (30) monitoring device includes a controller (42) that applies a selected electrical signal to tension members (32) of the load bearing member (30). In one example, connectors (40) are associated with ends of the load bearing member (30) to establish an electrical interface between the controller (42) and the tension members (32). The connectors (40) facilitate establishing electrical circuit loops along the tension members (32) such that only non-adjacent tension members are energized at a selected time. A variety of circuit configurations are disclosed. The applied electrical signal in one example has a potential that is negative compared to a ground potential of a hoistway in which the elevator belt is used. In another example, the electrical signal comprises a plurality of pulses and has a duty cycle that is on the order of about one percent.

    摘要： A method and system determines probable strength degradation in a tensile support in an elevator system by monitoring an electrical characteristic of the tensile support as a whole, such as the total electrical resistance of the tensile support, that varies as the remaining strength in the tensile support varies. One example system determines a relationship between strength degradation and various physical factors, such as the rate of degradation for a given load (102), operating environment information for the tensile support (104), and estimated usage data (106), to obtain a map of mean degradation (100). This map of mean degradation (100) is then used to generate one or more maps linking the strength degradation and electrical characteristic.

    摘要： Calibration of the state-of-charge (SOC) of a battery-based energy storage system used with a regenerative drive uses an SOC-open circuit voltage (V?oc#191) correlation. The battery is partially charged or discharged to assure operation defined by V?oc#191 following a known V?oc#191-SOC profile, such as a charge or discharge boundary curve. The partial charging/discharging may be synchronized with a traffic profile of an elevator system driven by the regenerative drive. A V?oc#191 measurement is made, and by enhancing the relaxation dynamics of V?oc#191 through regulating battery usage with a reference to traffic profile, a V?oc#191 is estimated more reliably. Using the estimate V?oc#191 and the known V?oc#191-SOC profile, state-of-charge of the battery is determined.

    摘要： A system (10) manages power from a secondary power (30) source to supply power to elevator and building systems (18) after failure of a primary power source (20). An available power monitor provides a measure or estimate (such as state-of-charge) of the power available from the secondary power source. A demand monitoring system (46) generates a signal related to passenger demand for each elevator in the elevator system. A controller (34) then prioritizes allocation of power from the secondary power source to the elevator and building systems based on the available power from the secondary power source and the passenger demand in the elevator system.
