The present invention relates to a system for measuring noise, vibration and running speed of an elevator, wherein the system can measure noise, vibration, running speed, etc. of an elevator through wireless communication in a state in which an operator is not in the elevator, to analyze riding quality, running state etc. The present invention provides a system for measuring noise, vibration and running speed of an elevator and an escalator, the system comprising: a measurement body installed on an inner floor or a step tread of an elevator or an escalator an acceleration sensor and noise sensor installed in the measurement body and a display device allowing data obtained by the acceleration sensor and noise sensor to be identified outside through wireless communication. 1. A system for measuring noise , vibration and running speed of an elevator and escalator which comprises:{'b': 31', '1', '10', '20, 'a measurement body to be installed on the inner floor or a step tread of an elevator or an escalator ;'}{'b': 32', '31', '10', '20, 'an acceleration sensor installed on the measurement body to detect the acceleration of the running elevator or escalator ;'}{'b': 33', '31', '10', '21', '30, 'a noise sensor connected to the measurement body to detect noise inside the elevator or noise on the predetermined position above the step tread of the escalator ;'}{'b': 34', '31', '32', '33', '46', '47', '32', '33, 'a control unit installed on the measurement body to receive and process data from the acceleration sensor and the noise sensor and the control unit having a communication module to communicate with outer device wirelessly and a memory to save the data from the acceleration sensor and the noise sensor ; and'}{'b': 35', '31', '31, 'a display device being separated from the measurement body , receiving data from the measurement body and displaying the data including speed, vibration, decibel of noise and angle by numerical value or graph; wherein'}{'b': 34', '35', '47', ...
