  Hereinafter, embodiments of a control panel device according to the present invention will be described with reference to the drawings. In the following description, the present invention may be described with specific examples, but the present invention is not limited to the following specific examples.

  A control panel device is a panel that houses circuit blocks and wiring and is used for BA (building automation) and HA (home automation). An electric board or various communication control boards may be used. In the following, an electric lock control panel that is connected to a non-contact IC card reader, a signal input / output device that is an electric lock unit, and the like and used for entrance / exit management is exemplified as the control panel device.

  As shown in FIG. 1, the control panel device 1 includes a substantially box-shaped panel casing 2 having a hollow inner space S that is open on one surface, and a front plate 3 that covers one surface of the panel casing 2. In the internal space S, a control board 15 (for example, a CPU) for controlling a signal input / output device (non-contact IC card reader 13, electric lock unit 14, see FIG. 2) provided outside the panel housing 2 is provided. , See FIG. 2), three terminal units 5 (5a, 5b, 5c) that relay the control board 15 and the signal input / output device, and terminal units 5 (5a, 5b, 5c) and three power supply units 6 (6a, 6b, 6c) for supplying power to the control unit 4, and signal transmission for inputting / outputting signals between the terminal unit 5 (5a, 5b, 5c) and the signal input / output device The signal line 7 to be wiring and the signal line 7 are included. Line 7 terminal unit 5 (5a, 5b, 5c) and the signal line wiring path 9 having a signal line lead-out portion 8 for drawing toward, is provided.

  The three power supply units 6 (6a, 6b, 6c) are arranged on the right side toward the internal space S of the panel housing 2 along the vertical direction, which is the direction connecting the top surface and the bottom surface of the panel housing 2. ing. The three power supply units 6 (6a, 6b, 6c) are drawn into the inside of the panel casing 2 through the power line insertion hole 10 provided on the top surface of the panel casing 2 and the electric wire hole 11 of the control unit 4. The power line 12 and the control unit 4 are connected to each other. The three power supply units 6 (6a, 6b, 6c) independently generate DC power, the power supply unit 6a supplies DC power to the terminal unit 5a, and the power supply unit 6b supplies DC power to the terminal unit 5b. The power supply unit 6c supplies DC power to the terminal unit 5c. That is, the power supply unit 6a is a DC power supply circuit for the terminal unit 5a, the power supply unit 6b is a DC power supply circuit for the terminal unit 5b, and the power supply unit 6c is a DC power supply circuit for the terminal unit 5c.

  Further, as shown in FIG. 2, the three power supply units 6 (6 a, 6 b, 6 c) independently supply, for example, direct current power generated to a value of 24 volts to the control unit 4. Therefore, if only one of the three power supply units 6 (6a, 6b, 6c) can generate DC power and supply it to the control unit 4, the control board 15 can be driven. As a result, even if a DC power supply function lowering event or a stop event such as malfunction due to manufacturing variations of the three power supply units 6 (6a, 6b, 6c) or damage to parts due to deterioration over time occurs, the control board 15 is stopped. Can be reduced as much as possible. Further, since the driving power sources of the three terminal units 5a, 5b, and 5c are dedicated driving power sources of the three power source units 6a, 6b, and 6c, any one of the three terminal units 5a, 5b, and 5c (for example, 5b The remaining two terminal units (for example, 5a and 5c) can continue to operate even in the event of failure or replacement.

  The control unit 4 includes an insulating constant voltage generation circuit 16, and the 24 volt DC power supplied from the three power supply units 6 (6 a, 6 b, 6 c) to the control unit 4 is provided in the control board 15. Before being supplied to the weak electric circuit, the voltage is lowered from the 24 volt value to the 5 volt value or the like by the insulated constant voltage generating circuit 16 and then supplied.

  As shown in FIG. 1, the three terminal units 5 (5a, 5b, 5c) are arranged on the left side of the three power supply units 6 (6a, 6b, 6c) toward the internal space S of the panel housing 2. 2 are juxtaposed along the vertical direction. That is, the three terminal units 5 (5a, 5b, 5c) and the three power supply units 6 (6a, 6b, 6c) each appear forward when the front plate 3 of the panel housing 2 is opened. To do. By adopting such a configuration, the terminal unit 5 (5a, 5b, 5c) and the power supply unit 6 (6a, 6b, 6c) are juxtaposed in the depth direction toward the internal space S of the panel housing 2. Compared to the case, the terminal unit 5 (5a, 5b, 5c) and the power supply unit 6 (6a, 6b, 6c) can be easily replaced. Here, the three terminal units 5 (5a, 5b, 5c) are pre-wired to the control board 15 via the slot connector 18 (see FIG. 5) and are configured to be able to communicate with each other. Yes. The three terminal units 5 (5a, 5b, 5c) and the control board 15 are connected in series as shown in FIG. 2, but may be connected in parallel as shown in FIG. Even if a failure occurs in any communication (for example, communication between the terminal unit 5b and the control board 15) by connecting in parallel, the remaining communication (for example, communication between the terminal unit 5a and the control board 15, Communication between the terminal unit 5c and the control board 15 is normally performed. The terminal unit 5 (5a, 5b, 5c) relays a signal from the non-contact IC card reader 13 to the control board 15 and a signal from the control board 15 to the electric lock unit 14. Here, the control board 15 performs personal authentication based on a signal from the non-contact IC card reader 13, and controls whether the electric lock is unlocked or remains locked according to the authentication result. In the present embodiment, the non-contact IC card reader 13 and the electric lock unit 14 are illustrated as signal input / output devices. However, the present invention is not limited to this, and instead of the non-contact IC card reader 13, for example, heat is applied. For example, an alarm device may be used instead of the human body monitoring sensor to detect, the fire sensor, the security sensor to detect the vibration of the window or door, and the electric lock unit 14. And, in the room where the non-contact IC card reader 13 and the electric lock unit 14 are provided, for example, a human body monitoring sensor for detecting heat, a fire sensor, a security sensor for detecting vibration of windows and doors, and an alarm device are provided, When the control board 15 receives signals from the human body monitoring sensor, the fire sensor, and the security sensor and detects that an abnormality has occurred in the room, the alarm device may be activated. Thereby, management of a room can be made more reliable.

  Further, as shown in FIG. 4, the three terminal units 5 (5a, 5b, 5c) are horizontally long cartridges 17 (17a to 17a) for performing signal input / output with a signal input / output device provided outside the panel housing 2. 17g) is provided so as to be attached to or detached from the base 19 which is arranged in parallel in the vertical direction of the internal space S of the panel housing 2 and serves as a base. The cartridge 17 (17a) ˜17 g) A signal line connection terminal 20 for connecting the signal line 7 is provided on each entire surface.

  Further, each of the cartridges 17 (17a to 17g) is provided with a signal line 7 connected to the cartridge 17 (17a to 17g) so as to be positioned below the signal line connection terminal 20 on the front plate 3 side of the panel housing 2. A signal line support plate 21 to be supported is projected. By adopting this configuration, the signal line 7 is not pulled down due to gravity and is not drooped further, so that the appearance of the wiring can be improved and the connection of the signal line 7 is ensured. Can do. In addition, in order to improve the appearance of the wiring, it is also conceivable to connect the signal line 7 so that the signal line 7 extends only from the signal line drawing portion 8 to the signal line connection terminal 20 of the cartridge 17 (17a to 17g). However, the wiring is not preferable. This is because, in this case, since the signal line 7 is pulled, the connection of the signal line 7 becomes uncertain when the state is extended for a long time, and noise is easily generated in signal transmission. This is because the waveform may not be correctly transmitted, or the signal line 7 may be disconnected from the signal line connection terminal 20 of the cartridge 17 (17a to 17g) and the communication may not be performed at all. is there.

  Here, as shown in FIG. 5, each of the cartridges 17 (17 a to 17 g) is formed with a claw portion 22 at one end in the laterally long direction so that the cartridge 17 (17 a to 17 g) can be easily attached to and detached from the base 19. On the signal line wiring path 9 side of the base 19, there is formed a claw hooking portion 23 for engaging and positioning the cartridge 17 (17a to 17g) by engaging with the claw portion 22. FIG. 5 shows only the cartridge 17d among the cartridges 17 (17a to 17g). And the cartridge 17 (17a-17g) is fixed to the base 19 with the screw | thread 24 in the part on the opposite side to the nail | claw part 22, for example. By adopting this configuration, the cartridge 17 (17a to 17g) can be easily replaced. Here, the engagement structure of the claw portion 22 and the claw hook portion 23 is adopted on the signal line wiring path 9 side when the claw portion 22 and the claw hook portion 23 are engaged. This is because it does not get in the way, but the wiring becomes an obstacle when the cartridge 17 (17a to 17g) is fixed to the base 19 with, for example, the screw 24. In addition, if the shape design is made so that the upper and lower limits of the engaging angle between the claw portion 22 and the claw hook portion 23 are widened, the cartridge 17 (in the lateral width space that does not protrude so much from the lateral direction of the base 19. 17a to 17g) is replaced, so that it is not necessary to lengthen the vacant dimensions on both sides of the base 19 to replace the cartridge 17 (17a to 17g), and the lateral dimension of the control panel device 1 becomes longer. One of these can be eliminated.

  The base 19 is provided with a power on / off switch 25 for turning on or off the supply of power to each of the cartridges 17 (17a to 17g). Thereby, when only a specific cartridge (for example, 17d) is replaced, it is not necessary to stop the supply of power to the other cartridges (for example, 17a to 17c, 17e to 17g).

  As shown in FIG. 1, the signal line wiring path 9 is a frame for centrally arranging the signal lines 7 connected to the cartridges 17 (17 a to 17 g) on the left side toward the internal space S of the panel housing 2. And is formed of a U-shaped material having an opening on the front plate 3 side, and is placed on the left side of the three terminal units 5 (5a, 5b, 5c) toward the internal space S of the panel housing 2. 2 are provided along the vertical direction. For this reason, the signal line 7 can be accommodated in the signal line wiring path 9 and the wiring work can be easily performed. The signal line wiring path 9 is a signal line lead that pulls out the included signal line 7 at a position corresponding to the cartridge 17 (17a to 17g) on the side surface on the terminal unit 5 (5a, 5b, 5c) side. A part 8 is provided. Specifically, it is preferable that the signal line lead-out portion 8 is on the left side of the cartridge 17 (17a to 17g). Further, the signal line lead-out portion 8 may be provided at the same interval as the cartridge 17 (17a to 17g) in the vertical direction on the side surface of the signal line wiring path 9 on the terminal unit 5 (5a, 5b, 5c) side. . In the present embodiment, a hole formed in the shape of a fence in the signal line wiring path 9 is used as the signal line drawing portion 8. In the example shown in the drawing, holes are also provided on the side of the signal line wiring path 9 that does not correspond to the cartridge 17 (17a to 17g) and on the side opposite to the terminal unit 5 (5a, 5b, 5c). However, the hole is not always necessary. Further, the signal line wiring path 9 only needs to include the signal line lead-out portion 8, and other configurations (for example, a plate or a lower plate opposite to the terminal unit 5 (5a, 5b, 5c)) are not necessarily provided. Not necessary.

  Then, the signal line 7 included in the signal line wiring path 9 is pulled out from the signal line leading portion 8 as necessary, and connected to the signal line connecting terminal 20 of the cartridge 17 (17a to 17g). .

  Therefore, the signal line 7 included in the signal line wiring path 9 is pulled out from the signal line drawing portion 8 in the lateral direction of the panel housing 2 of the control panel device 1 as necessary, and the cartridge 17 (17a to 17g). Therefore, the terminal unit 5 (5a, 5b, 5c) can be placed up and down, and the lateral dimensions of the control panel device 1 do not have to be increased. Not only can the vertical dimension be designed to be short, but the complicated wiring of the signal line 7 connected to the terminal unit 5 (5a, 5b, 5c) can be eliminated, and wiring work can be easily performed.

  Further, the signal line wiring path 9 prevents the signal line 7 from being exposed as a so-called piping member by attaching a cover plate (not shown) that covers the front surface in a state where the signal line 7 is included.

  In addition, by arranging the signal line wiring path 9 on the left side toward the internal space S of the panel housing 2, the signal line can be drawn from the left to the right. This is the preferred form in countries with many.

  Therefore, if only one of the plurality of power supply units 6 (6a, 6b, 6c) can generate power and supply it to the control unit 4, the control unit 4 can be driven. Even if a power supply function lowering event or a shutdown event such as malfunction due to manufacturing variations of the unit 6 (6a, 6b, 6c) or parts damage due to aging deterioration occurs, the risk of the control unit 4 stopping is reduced as much as possible. be able to.

  Further, when only a specific cartridge (for example, 17d) is replaced, it is not necessary to stop the supply of power to the other cartridges (for example, 17a to 17c and 17e to 17g).

  Further, the terminal unit 5 (5a, 5b, 5c) and the power supply unit 6 (6a, 6b, 6c) are compared with the case where the terminal unit 5 (6a, 6b, 6c) is arranged in parallel in the depth direction toward the internal space S of the panel housing 2. (5a, 5b, 5c) and the power supply unit 6 (6a, 6b, 6c) can be easily replaced.
