Embodiment Construction

[0050] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0051] Such as figure 1 As shown, the method for accurately and quickly measuring the stopping distance of an escalator according to the present invention includes:

[0052] Step S101: pick up and adjust the three-axis acceleration signal;

[0053] Step S102: The triaxial acceleration signal is low-pass filtered, and then integrated and vector combined to obtain the actual running speed and actual running displacement; the formula used for the integral is n>1, Δt is the interval between two points, β is the value after integration, and α is the value before integration; the three-axis signals are respectively defined as X, Y, Z, and the vector synthesis formula is A is the synthesized acceleration or velocity or displacement, X is the accele...

Abstract

The invention discloses a method for accurately and quickly measuring escalator stopping distance. The method includes: a, picking and adjusting triaxial acceleration signal; b, subjecting the triaxial acceleration signal to low pass filtering, integration and vector synthesis to obtain actual operating speed and actual operating displacement; c, judging whether an escalator reaches a constant-speed state or not according to the actual operating speed obtained in the step b; d, making escalator stopping events by manually triggering a remote triggering switch, and simultaneously using an escalator performance analyzer to automatically record a current collection data point position A; e, judging whether the escalator is stopped or not according to the actual operating speed obtained in the step b during the process of manually making the escalator stopping events, and automatically recording a stopping point position B by the escalator performance analyzer; and f, calculating displacement between the position A and the position B to obtain a stopping distance. In addition, the invention further provides a device for implementing the method.

Description

Technical field: [0001] The invention relates to electronic measurement and data processing, in particular to a method and device for accurately and rapidly measuring the stopping distance of an escalator. Background technique: [0002] Escalators and moving walks are special equipment for continuous transportation of personnel. They have become important personnel transportation tools in public places due to their stable operation, safety and reliability, strong transportation capacity, and convenient use. They are widely used in airports, supermarkets, and hypermarkets. , hotels, hospitals, guesthouses and other public places. [0003] The brake is an important part to ensure the normal and safe operation of the escalator. It can ensure that the escalator is reliably stopped when it encounters a power failure or other emergencies. Therefore, its braking force should meet the braking requirements, so that the escalator can stop according to the required deceleration and st...
