Problems solved by technology

However, this judgment method is not real-time judgment, and the wind pressure will be consumed during the bow raising process. When the bow is not in place and the wind pressure is not satisfied, there will be a serious problem of arc pulling, which will damage the pantograph and the power grid; and it is only suitable for DC power supply Subway train power input, the application area is narrow, not suitable for 25kv power supply trains such as urban trains, intercity EMUs, EMUs, high-speed trains, nor for higher voltage level power supply inputs

Embodiment 1

[0037] In a typical embodiment of the present invention, such as figure 1 As shown, the present invention proposes a fully automatic control method for raising the bow and closing the main break of the train, and collecting the total wind cylinder pressure F through the pressure sensor 总 , Auxiliary air cylinder pressure F 辅 , through the data acquisition module, and then transmit the information to the MCU control module, the MCU control module makes logical judgments, controls the operation of the auxiliary air compressor, the pantograph control circuit, and the main circuit breaker control circuit, so as to realize the fully automatic lifting of the train, Close the main circuit breaker.

[0038] Among them, the above-mentioned total wind cylinder is mainly to provide the train total wind for the train; the auxiliary wind cylinder is mainly to provide the train auxiliary wind for the train; the pressure sensor is used to detect the pressure of the total wind cylinder and t...

Embodiment 2

[0049] This embodiment mainly discloses a system involved in a fully automatic control method for raising the bow and closing the main break of a train, which mainly includes a main wind cylinder, a total wind pressure sensor, an auxiliary air cylinder, an auxiliary air pressure sensor, a data acquisition module, MCU control module, main circuit breaker control circuit, pantograph control circuit, auxiliary air compressor control circuit. The present invention collects the total air cylinder pressure and the auxiliary air cylinder pressure through the pressure sensor, transmits the information to the MCU control module through the data acquisition module, and the MCU control module performs logical judgment to control the auxiliary air compressor and the pantograph control circuit , The main circuit breaker controls the circuit action to realize the fully automatic bow raising and closing of the main circuit breaker of the train.

[0050] Further, the main circuit breaker cont...

Abstract

The invention discloses a train full-automatic pantograph rising and main circuit breaker closing control method and system and a rail vehicle. The method comprises the steps that the pressure of a main air cylinder and the pressure of an auxiliary air cylinder are obtained; when the pressure of the main air cylinder is not lower than a set value A, a pantograph is controlled to rise, and a main circuit breaker is closed; when the pressure of the main air cylinder is lower than a set value A and the pressure of the auxiliary air cylinder is not lower than a set value B, a pantograph control circuit and the main circuit breaker control circuit are controlled to act; when the pressure of the main air cylinder is lower than the set value A, and the pressure of the auxiliary air cylinder is larger than a set value C and smaller than the set value B, an auxiliary air pressure machine is controlled to be started, the pantograph is controlled to rise, and when the value B is reached, the auxiliary air pressure machine is controlled to stop controlling the main circuit breaker to be closed; and when the pressure of the main air cylinder is lower than the set value A and the pressure of the auxiliary air cylinder is not greater than the set value C, the auxiliary air pressure machine control circuit acts, and when the pressure of the auxiliary air cylinder reaches a set value B, the auxiliary air pressure machine is controlled to stop, the pantograph is controlled to rise, and the main circuit breaker is closed.

Description

technical field [0001] The invention relates to a control method, system and rail vehicle for fully automatic bow raising and main breaking of trains. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the rapid development of my country's national economy, rail transit has also been vigorously developed and has become one of the effective means of passenger transportation and an important means of transportation for daily travel. The number of trains is increasing, the workload of daily maintenance is increasing, and the burden of train maintenance is increasing. If the operation is not done properly, it will cause problems such as severe arcing of the pantograph due to low wind pressure and failure of the main circuit breaker to close, duplication of work, and delays The departure time affects the operation order. [0004] In the patent appli...
