Problems solved by technology

However, in the technology of this patent document 3, there is also the following problem, that is, when installing or removing the built-in equipment unit 33, it must be operated not only from one side, but also from the other side, so that it is difficult to install, remove, Repairs and inspections, especially in emergency repairs, are labor-intensive
In addition, since the power line 37 is arranged on one side and the signal line 39 is arranged on the other side, the installation or removal of the built-in equipment unit 33 is performed from the bottom surface of the housing with poor operability, so that it is difficult to install the built-in equipment unit 33. or disassembly operation problems

Embodiment approach 1

[0056] use Figure 5-Figure 6 Embodiment 1 will be described. Figure 5 It is a block diagram showing the vehicle control device according to the first embodiment. basic technology Figure 1-Figure 2 Among them, as loads, there are mainly circuit structures for vehicle lighting and air conditioners, but Figure 5-Figure 6 Among them, as a load, there is mainly a circuit structure (VVVF) for a vehicle drive motor. The figure also shows the division of several functional modules. Figure 5 Among them, 1 is an overhead line, and 2 is the main body of the vehicle control device, and is connected to the overhead line 1 (the overhead line side and the ground side) through the input terminal group 3 . 4K, 4L, 4M, 4N, and 4E are functional modules, and all functional modules 4K, 4L, 4M, 4N, and 4E have the first interface area 5K, 5L, 5M, 5N, and 5E in which signal line terminal groups are concentrated. , the functional modules 4K, 4L, 4M, and 4N other than the functional module ...

Embodiment approach 2

[0067] Figure 7 It is a block diagram showing the vehicle control device according to the second embodiment. In addition, in each figure, the same code|symbol represents the same or a corresponding part, and the description is abbreviate|omitted. The same is true for the following. Figure 7 said in Figure 5 The switch circuit function module 4K housed in the vehicle control device case is separated from the device main body. Figure 7 Among them, 52 is the same switch circuit as the functional module 4K. 53 is a signal line, connected with the functional module 4E. 54 is a terminal group.

[0068] In the case of Embodiment 2, the functional module 4L of the monitoring circuit is connected to the overhead line 1, the reactor 7, the switch circuit 52, the functional module 4N of the overvoltage protection circuit, and the functional module 4M of the inverter, and plays a role in connection. In addition, it also plays various monitoring functions in the connection part. ...

Embodiment approach 3

[0074] Figure 9 It is a block diagram showing the vehicle control device according to the third embodiment. In particular, changes and additions to the functional modules 4 will be described. Here, in the case of changing the functional module 4N, the functional module 4P (overvoltage protection circuit) is mentioned. This functional module 4P controls the energy consumed by the braking resistor by the switching element and has the function of suppressing the overvoltage of the switching circuit 39. . In addition, as an additional functional module, a functional module 4Q (CCOS = control circuit cut out switch) having a switch function of cutting off a vehicle side circuit and a control circuit, and a functional module 4Q having a function of managing train information and issuing commands to various devices on the vehicle are mentioned. Functional function module 4R (train information management system). In addition, 50 is a braking resistor, and 51 is its connection term...

Abstract

The present invention provides a box-shaped vehicle control device provided under the floor or on the roof of a vehicle to supply electric power to equipment of the vehicle. The vehicle control device is made up of function modules (4) each having an interface surface (22) on one side where a first interface region (5) in which a signal-wire terminal is placed and a second interface region (6) inwhich an electric-power-wire terminal is placed are separated. The interface surfaces (22) are placed on one end side with the first interface region (5) as a common region and on the other end side with the second interface region (6) as a common region. The function modules have monitor circuits, overvoltage prevention circuits, and inverters.

Description

technical field [0001] The present invention relates to a control device for a vehicle, which is installed in a box shape under the vehicle or on the roof of the vehicle, and is used for supplying electric power to vehicle equipment and the like. Background technique [0002] For example, Patent Document 1 and Patent Document 3 disclose equipment installed in a box shape under a vehicle. Also, for example, Patent Document 2 discloses a device installed in a box shape on the roof of a vehicle. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2001-258263 ( image 3 ) [0004] Patent Document 2: Japanese Patent Laying-Open No. 7-17396 ( image 3 ) [0005] Patent Document 3: Japanese Patent Laying-Open No. 5-199601 ( figure 1 , figure 2 ) [0006] In the prior art of Patent Document 1, although the arrangement of the main components accommodated in the housing is described, there is almost no mention of the relationship between the arrangement of ele...
