The invention discloses a multi-sensor electronic scale landing detection system and method. The system comprises an electronic scale landing detection controller, a plurality of bidirectional multipath electronic switches and an upper computer, and a control switch or the upper computer triggers the electronic scale landing detection controller to control the bidirectional multipath electronic switches so as to realize switching between an electronic scale landing detection mode and a weighing mode. After a electronic scale landing detection mode is entered, a certain weight is loaded and unloaded at each sensor landing point of the electronic scale, whether each landing point falls to the ground and is true or not is judged according to the variation of two no-load signals before and after weight loading of the sensor, and after all the landing points are detected, a normal weighing mode of the electronic scale is entered. 本发明公开了一种多传感器电子秤着地检测系统及方法，所述系统包括电子秤着地检测控制器、多个双向多路电子开关和上位机，控制开关或上位机触发电子秤着地检测控制器控制双向多路电子
