The invention relates to the technical field of train speed adjustment, in particular to a train speed adjustment method and system using a train communication network, and the method comprises the steps: obtaining the pressure of each monitoring point in a train at each moment and the rail humidity at each moment from the train communication network; the train speed, the transverse acceleration, the longitudinal acceleration and the vertical acceleration of the train at each moment during running are obtained; determining the weight imbalance degree of the train at each moment; determining transverse energy, longitudinal energy and vertical energy at each moment; determining an energy synthesis index at each moment; determining the operation risk degree, the humidity influence degree and the slip influence degree of the train at each moment; determining a scale factor of the fuzzy control algorithm at each moment; and in combination with a fuzzy control algorithm, the adjustment amount of the acceleration is determined, and the speed of the train is adjusted. According to the method, the accuracy and timeliness of train speed adjustment are improved, and the phenomena of sideslip and wheel slip when the train runs on a rail with high humidity are avoided.
