The invention provides an elevator safety evaluating system based on data fusion. The elevator safety evaluating system comprises a speed monitoring unit, a tension monitoring unit, a vibration monitoring unit, a pressure monitoring unit, a first fusion unit, a voltage monitoring unit, a second fusion unit, a first judgment unit, a second judgment unit, a third judgment unit, a comprehensive judgment platform, a liquid crystal display unit, a wireless transmission and a peripheral storage unit. A first fusion parameter is constructed by integrating the running speed of an elevator car and a tension signal of an elevator dragging steel rope, and a second fusion parameter is constructed by integrating a vibration signal during running of the elevator car and a gravity signal borne in the elevator car; and in addition, the voltage monitoring unit is used for monitoring the stability of a voltage signal when an elevator traction machine works, the parameters are integrated to effectively evaluate the operation sa
