Disclosed is an elevator system having: a holding relay configured to energize and deenergize a circuit, the holding relay configured to communicate over a wireless network with a mobile device, wherein the holding relay is configured to: deenergize the circuit responsive to receiving a first signal via the wireless network from the mobile device, indicative of the mobile device being in or near a first architectural location.

Emergency stop system for elevator

A method of monitoring a conveyance system is provided. The method including: monitoring vibratory signatures along a first axis of a conveyance apparatus of a conveyance system; detecting a vibratory signature along the first axis about equivalent to a vibratory signature of significant event; and examining vibratory signatures for a secondary event along at least one of the first axis and a second axis of the conveyance apparatus for at least one of a selected time period after detection of the significant event and a selected time period before detection of the significant event.

Monitoring of conveyance system vibratory signatures

Methods and systems for determining elevator car locations are provided. Aspects includes a sensor affixed to a moving component of an elevator system, wherein the sensor is operated by a controller and wherein the controller is configured to determine that the elevator car is in motion based at least in part on the sensor. A direction of the elevator car is determined while the elevator car is in motion based at least in part on the sensor. Sensor data associated with the elevator car is collected while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion. Elevator car travel data is accessed from a travel time profile associated with the elevator car and the travel time is compared to the elevator car travel data to determine a location of the elevator car in a hoistway.

Elevator sensor system floor mapping

A method for monitoring thresholds for performance attributes in an elevator system is provided. Aspects includes collecting, by a sensor affixed to an elevator car, sensor data associated with the elevator system wherein the sensor data comprises one or more performance attribute values for a set of performance attributes of the elevator system. Obtaining a threshold profile associated with the elevator system, wherein the threshold profile comprises thresholds for each performance attribute in the set of performance attributes of the elevator system. Comparing the one or more performance attribute values to corresponding thresholds for the set of performance attributes and transmitting an alert for any of the one or more performance attribute values exceeding the corresponding thresholds for the set of performance attributes.

Variable thresholds for an elevator system

A lone worker system for performing a safety check is provided. The lone worker system includes a mobile device. The mobile device includes a memory storing a safety check application thereon and a processor. The processor is coupled to the memory and executes the safety check application. The processor initiates the safety check application with respect to the service call. The safety check application executes a use-case safety monitoring of the mobile device with respect to a service call to implement the safety check. The use-case safety monitoring detects an emergency situation with respect to a connectivity of the mobile device to a server, an activity of the mobile device, and a motion of the mobile device.

An equipment service graphical interface is provided. An entity and an entity location of a plurality of equipment are identified. A data repository is accessed that includes a plurality of equipment servicing data associated with the equipment at the entity location. A map image is output on a graphical user interface including one or more icons indicating one or more equipment locations and status of the equipment based on the equipment servicing data from the data repository. One or more equipment status details are selectively displayed on the graphical user interface responsive to a detected user input action.

Equipment service graphical interface

A method of warning a technician is provided. The method comprising: detecting a wireless signal emitted by at least one of a sensor and a user device; determining a distance between the sensor and the user device in response to the wireless signal; determining whether the user device is within a work area in response to the distance between the sensor and the user device; and conveying safety instructions through an application installed on the user device when the user device is determined to be within the work area.

Work area technician warning system

An elevator door wedge monitoring system is provided. The elevator door wedge monitoring system comprising: an engagement sensing system configured to detect an engagement parameter, wherein the engagement parameter indicates whether an elevator door wedge is properly engaged with an elevator door; a communication device in electronic communication with the engagement sensing system and configured to receive the engagement parameter from the engagement sensing system; and an application installed on a user device in wireless communication with the communication device; wherein the communication device is configured to transmit the engagement parameter to the application.

Display screen or portion thereof with graphical user interface

A lone worker system for performing a safety check is provided. The lone worker system includes a mobile device. The mobile device includes a sensor and a memory storing a safety check application thereon and a processor. The processor is coupled to the memory and executes the safety check application under a motion mode including an active tracking of a fall motion event by the sensor. In response to the fall motion event being detected during the active tracking, the processor operates a count utilizing a timer of the safety check application. If the count exceeds a predetermined amount of time, the safety check application enters an emergency mode to execute an emergency alert.

Lone worker fall detection

A service tool is provided. The service tool includes a transceiver communicatively coupled to a wireless access device physically connected to a mechanical system. The service tool includes a memory storing a service tool application software thereon. The service tool includes a processor executing the service tool application software to execute at least one of a plurality of operability support levels by the service tool for the mechanical system. The plurality of operability support levels includes an adjuster/construction level. The adjuster/construction level includes security provisions for control of the mechanical system.

Mechanical system service tool

A safety headwear monitoring system is provided. The safety headwear monitoring system comprising: a sensor configured to detect a status parameter, wherein the status parameter indicates whether an object is located within a selected distance of the sensor; a transmission device in electronic communication with the sensor and configured to receive the status parameter from the sensor; and an application installed on a user device in wireless communication with the transmission device; wherein the transmission device is configured to transmit the status parameter to the application.
