Non-contact escalator deflection measuring device and method

The invention discloses a non-contact escalator deflection measuring device and method, the non-contact escalator deflection measuring device comprises an operation host, a laser measuring device and a laser tracking device, the operation host comprises an electronic display screen, a wireless transceiver module and a data processing unit. The laser tracking device is fixedly installed on a baseboard of an upper end station of an escalator through an installation device, after the laser tracking device is installed, laser emitted by a laser sensor directly irradiates the target center of a laser tracking target, the laser moves on the laser tracking target along with ascending of the escalator, and therefore deflection and speed parameters of the escalator are obtained. The data processing unit sends the processed data to the operation host through the wireless transceiver module, and result data is displayed in real time. Compared with a traditional mode, the non-contact escalator deflection measuring device
