Problems solved by technology

This method is simple to operate, but it is greatly affected by human factors and the measurement accuracy is not high
There are also some instruments or devices on the market that measure the stopping distance. These instruments and devices can only be operated by special personnel, and the inspection efficiency is not high. More importantly, they can only reflect the status of the escalator at the time of inspection.

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] Such as figure 1 with figure 2 Shown, a kind of escalator stop distance online detection method, comprises the following steps:

[0026] A. After the escalator is running normally, press the emergency stop button or cut off the power to stop the escalator, and obtain the stop start signal;

[0027] B. The processor receives the pulse signal transmitted by the encoder to obtain the stopping distance of the escalator;

[0028] C. Compare with the allowable braking distance range, if it exceeds the allowable range, it will give an alarm;

[0029] D. The comparison result is wirelessly transmitted to the handheld device terminal.

[0030] The processor receives the switching signal sent by the auxiliary contact of the brake contactor as the start signal of braking, starts the internal pulse counter, and ends until the speed of the es...

Abstract

The invention discloses an escalator stopping distance online detection method and device. The method comprises the steps that a stopping start signal is obtained; the escalator stopping distance is obtained; the escalator stopping distance is compared with an allowable stopping distance range; and a comparison result is wirelessly transmitted to a handheld equipment terminal. The device comprisesan encoder module used for generating pulse signals to measure the running distance of an escalator, a stopping signal module used for generating synchronizing signals when the escalator starts to bestopped, a processor and a handheld terminal used for displaying and storing measured data. The encoder module and the stopping signal module are connected with the processor through cables respectively, and the processor transmits data obtained through processing to the handheld terminal in a wireless transmission mode. The method and device have the beneficial effects that the escalator stopping distance can be accurately and quickly measured online only by installing the detection device once, data can be obtained without operation of professionals, and when the measured stopping distanceexceeds an allowable value, an alarm is given for prompting, so that the stopping performance of the escalator is judged, and the operation is simple.

Description

technical field [0001] The invention relates to a detection method and a detection device for a braking distance, in particular to an online detection method and a detection device for an escalator braking distance. Background technique [0002] The brake is an important part to ensure the normal and safe operation of the escalator, and it can ensure the reliable braking of the escalator in emergency situations. Therefore, the braking capacity of the escalator must meet the requirements. The braking distance directly reflects the braking capacity of the escalator. If the braking distance is too large, the braking force will be too small, making it impossible to stop reliably; if the braking distance is too small, the deceleration will be too large, and passengers will easily fall due to inertia. As an important basis for verifying the performance of the brake, the stopping distance of the escalator is currently an important item of the statutory inspection. [0003] At pre...
