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.
