Weighing structure and gravity detection method of rail transit platform safety pedal

Abstract

The invention discloses a weighing structure of a platform safety pedal in rail transit and a gravity detecting method, wherein two kinds of weighing methods are combined. According to one weighing method, the weight is directly used as a measuring unit; the method is direct and accurate; and on condition that a heavy object exists on a sliding pedal, high sensitivity and high detection precision are realized, and the weighing method can be used for detecting the heavy object with a relatively small size. The other weighing method is an indirect weighing method in which detection for a driving current is used as a facility. The second weighing method has advantages of small effect by an external environment, and stable detection result. According to the two methods, a fitting determination principle is used in normal operation, the direct weighing method is mainly used and the current detection method is used as a supplement. Mutual determination is adopted. No preset least weight on the pedal is ensured, and a contraction instruction is performed safely. Compared with the prior art, the weighing method provided by the embodiment of the invention has advantages of high accuracy, high efficiency, high reliability and no influence by the external environment.

Description

technical field [0001] The invention relates to rail traffic safety assurance technology, in particular to a weighing detection technology for rail traffic safety pedals. Background technique [0002] In the process of rail transit construction, in order to ensure the safe running of trains, there is often a certain gap between the platform and the train body, which brings certain safety hazards to passengers. During the process of getting on and off the bus, passengers are likely to trip over the gap, or get their feet stuck in the gap due to stepping on the air. In order to solve this problem, the prior art provides a retractable rail transit platform safety pedal, which is used to fill the gap between the rail transit platform and the train door when the train arrives, preventing passengers from being caught by the gap when getting on and off the train. Tripping, or getting your foot caught in a gap by stepping through the air. [0003] This safety step is installed on ...
