Problems solved by technology
Especially in the case of a failure of the current continuous train, due to the characteristics of the single-track operation of the subway line, the subsequent trains are likely to become more crowded and denser, resulting in too many trains on one power supply arm, which exceeds the power supply load and causes a wider range of failures
The existing signal system cannot grasp the real-time power supply situation of the power supply system, cannot establish the relationship between power supply and driving, and cannot perform automatic control
It is difficult for dispatchers to pay attention to the number of trains on each power supply arm in real time

Embodiment Construction
[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0056] refer to Figure 1-3 , to illustrate the technical method of the present invention, first of all, refer to figure 1 , introduces the calculation method of the load capacity of the power supply arm. Second, refer to figure 2 , which shows the calculation method of the power supply load required by the train under different weighing conditions. Again, refer to image 3 , to illustrate the method of dynamically controlling the number of trains and...

The invention relates to a rail transit train control method and device based on power supply capacity and a medium, and the method comprises the steps: collecting power supply and vehicle data in real time, analyzing the change of a power supply mode in real time, and dynamically calculating the maximum number of trains allowed to run on a current power supply arm in real time according to the current load condition; when the number of the trains running on the power supply arm reaches the maximum allowable number of the trains, stopping the follow-up trains automatically, and delaying the trains to enter the power supply arm; when a blocking mode occurs, starting the trains in the same power supply arm in a staggered mode according to the starting curve of the trains, and impact on the power supply system caused by simultaneous starting is avoided. Compared with the prior art, the method has the advantages that the problem of serious operation faults caused by fault tripping due to too many trains on the same power supply arm is avoided, and the like.
Description
technical field [0001] The invention relates to a rail traffic signal system, in particular to a rail traffic train control method, equipment and medium based on power supply capability. Background technique [0002] There is an upper limit for the number of trains supported by the traction power supply facilities of rail transit lines. If too many trains enter a power supply arm and exceed the upper limit of the load of the power supply arm, the power switch will trip due to excessive load current and cause a large Failure effects. This phenomenon is particularly evident in the busy lines in megacities. Especially in the case of a failure of the current continuous train, due to the characteristics of the single-track operation of the subway line, the subsequent trains are likely to become more crowded and denser, resulting in too many trains on one power supply arm, which exceeds the power supply load and causes a wider range of failures. The existing signal system cannot...
