SYSTEM FOR ANALYZING ELEVATOR PERFORMANCE

摘要

The present invention is an elevator performance analysis device and process. It comprises a sensor package, a computing device, a computer program, and a communication mechanism between the sensor package and the computing device. The sensor package is physically separate from the computing device comprising a sensor for measuring the acceleration of the elevator car, an integral door position sensor for determining the position of the elevator door, a sensor for measuring the altitude of the elevator car, and an interface to an external communication mechanism for communicating with the computing device. The computing device comprises a processor for running computer programs, memory, electronic storage for programs, data, and analysis results, a display, and a communication mechanism for communicating with the sensor package. The computer program controls the system, analyzes the signals from the sensor package, displays the results of the analysis, and creates reports of the elevator performance.

主权项

1. An elevator performance analysis device, comprising:
a computing device comprising a computing processor for running computer programs, an electronic memory used by said computing processor while running a computer program, an electronic storage for indefinitely storing data files and computer programs, an electronic display for displaying graphics to a user, and an interface to an external communication mechanism for communicating with another physically separate device; a sensor package, physically separate from said computing device, comprising a sensor for measuring the acceleration of the elevator car, an integral door position sensor for determining the position of the elevator door, an altimeter for measuring the altitude of the elevator car, and an interface to an external communication mechanism for communicating with said computing device; a communication mechanism for exchanging commands and data between said computing device and said sensor package; a computer program stored in said electronic storage and running in said computing processor that repetitively requests acceleration measurements, door positions, and altitude measurements from said sensor package and analyzes said acceleration measurements, door positions, and altitude measurements, and manages the functions of said elevator performance analysis device; whereby said computer program computes the beginnings and ends of every trip of the elevator car so that the user need not indicate the beginnings and ends of any trip to said elevator performance analysis device; and said computer program computes the accelerations, velocities, jerks, door positions, door timing, landings, and trip details of the elevator car for every trip, displays the results of the computations on said electronic display, and stores the results and times of the computations for every trip in said electronic storage so that the number of results that are stored is limited only by the size of said electronic storage.
