Description
technical field [0001] The invention relates to the field of rail traffic signal and control, in particular to a signal machine control device for a rail traffic sand table. Background technique [0002] With the rapid development of my country's rail transit industry, there are two characteristics in the demand for professional talents: one is the increasing number of professionals; the other is the gradual increase in practical ability requirements. However, due to the particularity of the rail transit site and the stringent safety requirements, students cannot perform actual technical operations and fault detection and handling work during the on-site practice, and the effect of practice and training is greatly reduced. This seriously hinders the improvement of students' practical ability. Making a rail transit sand table suitable for teaching and controlled by real station interlocking equipment is an effective way to solve the above problems. The signal machine is one...
