Description

Smart wireless speedometer

The present invention relates to a smart radio speed meter, and more particularly, to a smart radio speed meter capable of providing convenience in measuring a running speed, a braking distance, and the like of an elevator, an escalator, etc. by a compact structure by a simple structure will be.

Generally, an elevator is installed in a building over a certain height and is raised or lowered to a desired floor. An escalator or a moving walk is installed so that the user can lift or move the upper and lower floors of the building automatically while standing on a tread.

Such automatic moving devices, such as elevators, escalators or moving walks, are subjected to periodic safety inspections to check for aging or abrasion of the components to prevent smooth operation or safety hazards of the device.

Conventionally, however, in order to check an operating condition such as a running speed, a braking distance, or a decelerating speed of an automatic moving mechanism, an inspection device is driven in a state in which an inspector is actually carried on a device in operation.

Such conventional inspection apparatuses and methods are not only compliant with the safety risks due to the fact that the inspectors directly ride on the automatic movement mechanism, and are accompanied by a troublesome operation due to the large and heavy inspection apparatus itself, Some equipment has difficulty in verifying the data measured at the inspection site.
