Embodiment 1

[0034] Such as image 3 As shown, the power supply control system provided by this embodiment includes an input terminal module 1 and an intermediate bus 2 , and the intermediate bus is arranged on a backplane 4 .

[0035] Furthermore, the power supply control system provided in this embodiment further includes a filter module 6 arranged between the external power supply and the input terminal module 1 .

[0036] The 110V input voltage of the external power supply firstly passes through the filter module 6 to perform electromagnetic interference (EMI) filtering on the input voltage, and realize functions such as anti-reverse connection and anti-shock.

[0037] The input terminal module 1 is preferably an isolated direct-current (DC-DC) converter, which converts the 110V input voltage for the first time to form an intermediate voltage, and inputs it to the intermediate bus 2 on the backplane 4 . In this embodiment, the intermediate voltage may be 24V. In other implementation ...

Embodiment 2

[0046] This embodiment is basically the same as Embodiment 1, as Figure 4 As shown, the difference is that in this embodiment, the filter module 6, the input module 1, the intermediate bus 2 and each load module 3 are arranged on the single board 9, and any load module 3 communicates with the corresponding module through the backplane 4 The function board 5 is connected.

[0047] Compared with the power supply control system provided in Embodiment 1, in this embodiment, the filter module 6, the input module 1, the intermediate bus 2 and each load module 3 are all arranged on a single board 9, which can be better integrated with The existing centralized power supply mode is compatible, and it is more flexible for the development of the power control system.

Embodiment 3

[0049] The power supply control system provided in this embodiment is a further improvement on the basis of the first embodiment. Such as Figure 5 As shown, the power supply control system is provided with two input terminal modules 1 and two intermediate buses 2 . One of the input modules converts the 110V input voltage into a 24V intermediate voltage, and the other input module converts the 110V input voltage into a -24V intermediate voltage, so that the intermediate voltages on the two intermediate buses are 24V and -24V respectively.

[0050] In this embodiment, the output voltage of each load-end module connected to the two intermediate buses can be flexibly set as required, and the two intermediate buses enable each load-end module to more conveniently convert the intermediate bus into the output voltage required by the load , It also further reduces the mutual influence between functional boards and improves the power quality.

Abstract

The invention discloses a power control system and a train control device and belongs to the electrical technical field. The power control system solves the problem that in the prior art, the cost of a power control system is too high. The power control system comprises an input end module and an intermediate bus connected with the input end module, wherein the input end module is used for converting the input voltage of an external power supply into the intermediate voltage on the intermediate bus. The power control system can be applied to train control devices and other places.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a power supply control system and train control equipment. Background technique [0002] In scenarios such as train control equipment, the power supply voltage required by each functional board to implement different functions is different, so the power control system is required to be able to provide multiple levels of output voltage for different loads. [0003] Existing power control systems such as figure 1 As shown, an external power supply (usually 110V direct current) is input to the power board 10, and the power board 10 converts the 110V voltage of the external power supply into multiple output voltages such as 24V, 15V, and 5V. The various output voltages output by the power board 10 are connected to the backplane 20 through the connectors, and then the output voltages are provided to the corresponding function boards 30 through the connectors. [0004] The invent...
