Tramcar signal control system and method based on dynamic multi-objective optimization control

Abstract

The invention provides a tramcar signal control system based on dynamic multi-objective optimization control. The system comprises an optimization target automatic selection subsystem, a tramcar load monitoring subsystem and a target optimization control engine. The tramcar load monitoring subsystem is used for monitoring the load capacity of the tramcar in the current time period in real time; the optimization target automatic selection subsystem matches at least one to-be-determined optimization target from a plurality of candidate optimization targets based on the current time period and the load capacity; and the target optimization control engine establishes a target optimization control model based on the to-be-determined optimization target, and changes the running state of the tramcar based on the regulation and control parameters obtained by the target optimization control model. The invention further discloses a control method implemented based on the system. According to the technical scheme, the operation optimization target can be dynamically changed in a self-adaptive mode according to the current monitoring parameters of the electric car, so that it is ensured that the operation state of the electric car is in the optimal state, and energy consumption, passenger experience and actual requirements are considered.

Description

technical field [0001] The invention belongs to the technical field of tram control, and in particular relates to a tram signal control system based on dynamic multi-objective optimization control, a control method, a control device and a computer-readable storage medium. Background technique [0002] Tram (Tram, Streetcar, Tramcar) is a light rail transit vehicle driven by electricity and running on the track. The tram is driven by electricity, and the vehicle will not emit exhaust gas, so it is a pollution-free and environmentally friendly means of transportation; and the construction cost of the tram is low (according to estimates, the investment required for a kilometer of road tram line is only three times that of a kilometer of underground railway. One-twentieth to one-twentieth), high safety factor, shared lanes (with grooved rails, cars and trams can share the same road), and have been vigorously promoted in eligible areas of many cities. [0003] However, a major d...

[0003] However, a major defect of the tram is that it travels slowly and has a small passenger capacity. In addition to the forward direction, in the actual operation process, it occasionally needs to slow down to avoid or even run backwards in a small distance, which leads to the operation of the tram. Low efficiency; in addition, some cities have established complex tram operation networks, and each tram also receives other signals from the dispatching system during operation, such as approach / entry / branch switch / pass / avoid / stop etc

[0004] In the prior art, the above process is manually controlled by the tram driver and sends command signals to frequently change the state of the tram, resulting in high energy consumption of the tram within a limited running distance, and frequent state changes also affect passengers. Riding experience; in addition, because the tram adopts a single scheduling strategy, its operation status is uncontrollable, so that the actual riding needs of passengers cannot be met (such as being late for work, being late), which may lead to a decrease in the utilization rate of the tram and reduce the use efficiency , and if the tram is in a state of low passenger flow for a long time, it will be difficult to operate normally, and its value to the area along the line will gradually dissipate
