The invention provides an ascending and descending operation and belt breakage detection method of an elevator. A transmission detection device and method for detection through synchronous rotation with a motor driving shaft are used, so as to integrally accelerate the ascending and descending speed of a cargo carrying platform and improve the stroke control precision of the cargo carrying platform; meanwhile, the monitoring disposal of the belt breakage and other abnormal ascending and descending states can be realized; and the problems of deviation and abrasion of a lifting belt are prevented and solved to the maximum degree. Specifically, the lifting belt connected with the cargo carrying platform cyclically bypasses through a driving module, a steering module and a direction changing module to form a closed loop operation track in the whole ascending and descending process through being driven by a servo motor; the driving module and the servo motor drive a main driving shaft to rotate; the lifting belt is driven to do ascending and descending operation through a driving belt wheel; the steering module is provided with an encoder at the end part of a steering shaft bypassing the lifting belt; the lifting belt drives the steering shaft to rotate, and the encoder outputs a frequency feedback signal; and by calculating and comparing the frequency feedback signal output by theencoder and a servo motor output signal, the practical ascending and descending stroke distance of the cargo carrying platform is calculated and is used as the basis of judging whether the lifting belt is broken or not.
