A network device power strip according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a network device power strip (hereinafter simply referred to as a power strip) 10 according to the first embodiment. FIG. 2 is a schematic explanatory diagram of the internal structure of the power strip 10 and network devices connected thereto. The power tap 10 is for supplying power to the line terminating device 110, the router 120, and the switching hub 130 (branching device) which are network devices. When the power is supplied, these network devices 110 to 130 are supplied. Connects to the Internet (external network) while building a local area network (LAN). Details of these network devices 110 to 130 will be described later.

  On the outer wall of the power strip housing 9, a first outlet (first power terminal) 1 for supplying power to the line terminator 110 and a second outlet (second power terminal) for supplying power to the router 120 are provided. ) 2 and a third outlet (third power terminal) 3 for supplying power to the switching hub 130 are provided, and the power plugs of the respective devices are inserted into the respective insertion ports 11, 21, 31. Thereby, each apparatus and the internal power supply control circuit 4 are electrically connected. Further, the power control circuit 4 obtains power from a household outlet provided on the wall of the house or the like by a power plug 81 provided at the tip of the power cord 82.

  The power supply control circuit 4 has a lightning protection circuit 41 and a supply delay circuit 43 in order from the power cord 82 side. The lightning protection circuit 41 is a circuit (so-called surge protector) for protecting subsequent circuits and devices from surges generated by lightning or the like. The supply delay circuit 43 is provided on the power supply paths 51 to 53 to the first to third outlets 1 to 3, and when the downstream device starts up in the network, the upstream device starts up. Thus, the timing of starting the power supply to the first to third outlets 1 to 3 is controlled at the start of power input.

  When receiving the power input, the supply delay circuit 43 starts supplying power in the order of the first outlet 1, the second outlet 2, and the third outlet 3. FIG. 3 shows a specific configuration example of the supply delay circuit 43. When the power supply input from the input line 54 is started, the supply delay circuit 43 activates a timer circuit when the voltage detection circuit detects a voltage, and the timer circuit drives an intermittent circuit (relay or the like) after a predetermined time. As a result, power is output to the output lines 51 to 53 in order. The power supply to the second outlet 3 and the third outlet 3 may be started at the same time. Further, in order to stably supply power to the first outlet 1, a timer and an intermittent circuit are provided for the output line 51 as in the modification (supply delay circuit 43 ′) shown in FIG. The start of power supply to 1 can be delayed with respect to the start of power input to the supply delay circuit 43.

  The supply delay circuit 43 may be any circuit that delays the start of power supply to the second outlet 2 at least from the start of power supply to the first outlet 1. The power supply to the second outlet 2 is preferably started after the line terminator 110 connected to the first outlet 1 is started up. In general, the time required to start up the line termination device 110 is about 3 seconds for the optical line termination device 110 and about 3 minutes for the ADSL modem and CATV modem. In addition, the switching hub 130 connected to the third outlet 3 is a network device that behaves passively, and since the order of startup is not particularly required, the third outlet 3 is not delayed in starting the power supply. Alternatively, the third outlet 3 can be provided as a separate system from the supply delay circuit 43.

  Further, as shown in FIG. 5, the power strip 10 has volumes 13, 23, and 33 on the outer wall of the power strip casing 9 that can change the start-up time by adjusting variable resistors, switches, etc. in the timer circuit. It can also be set as the structure provided. Thereby, the delay time of the power supply start can be freely changed according to the type of device to be connected. In addition, the present invention is not limited to the network device described above, and four or more outlets may be provided to connect various network devices such as a firewall, and the timing of starting the power supply thereof may be controlled.

(Second Embodiment)
A power tap for a network device according to a second embodiment of the present invention will be described with reference to the drawings. In the following, portions different from the first embodiment will be mainly described, and overlapping portions will be denoted by the same reference numerals in the drawing and description thereof will be omitted. 6 and 7 are external perspective views of the power strips 20 and 30 according to the second embodiment. FIG. 8 shows the internal structure. The power supply taps 20 and 30 include a supply interruption circuit 42 between the lightning protection circuit 41 and the supply delay circuit 43 in the power supply control circuit 4. That is, the supply interruption circuit 42 is provided on the power supply path 54 on the upstream side of the supply delay circuit 43, and the power input to the supply delay circuit 43 downstream (and power supply to the outlets 1 to 3). Is interrupted. The supply interruption circuit 42 is connected to a switch unit 61 for inputting a signal for interrupting the power input.

  With this configuration, when the restart switch 61b of the switch unit 61 is pressed, the power taps 20 and 30 once cut off the power supply to the network devices connected to the outlets 1 to 3, and then the above supply delay circuit described above. The network devices are collectively restarted while controlling the timing of starting the power supply to the first to third outlets 1 to 3 by the operation of 43. Here, the power tap 20 shown in FIG. 6 is one in which the switch portion 61 is integrally provided on the outer wall portion of the power tap housing 9. Further, the power tap 30 shown in FIG. 7 is connected to the supply interruption circuit 42 and is provided with a switch portion 61 at the end of the switch wiring 62 extending from the power tap housing 9 to the outside. Remote operation for restarting is possible by routing the wiring 62. For example, when the network devices 110 to 130 are installed in an inconspicuous place such as an electrical distribution board, the switch wiring 62 is routed so that only the switch unit 61 is installed on the wall of the room. This is useful because it is possible (see FIG. 19).

  FIG. 9 shows a specific configuration example of the supply interruption circuit 42. That is, an intermittent circuit (relay or the like) is provided on the power supply path, and current supply is interrupted by operating the intermittent circuit by an adjacent low voltage circuit. The low-voltage circuit is connected to the switch unit 61, and the low-voltage wiring is connected between them. The intermittent circuit is activated by a low-voltage signal input by pressing the restart switch 61b, and a high voltage (for example, AC100V) ) Is interrupted.

  Further, the supply delay circuit 43 and the supply interruption circuit 42 can be integrally configured using a microcomputer as shown in FIG. That is, when the microcomputer receives a signal for pressing the restart switch 61b, it supplies a signal to the intermittent circuit provided in the output lines 51 to 53 to cut off the power supply (function as the supply interruption circuit 42), and thereafter The device is restarted by stopping the signal at a predetermined timing and sequentially returning the power supply (function as the supply delay circuit 43).

  11 and 12, the switch unit 61 is configured to be detachable from the power strip housing 9, and the switch portion 61 is provided integrally with the power strip housing 9 shown in FIG. The power strip 20 and the power strip 30 provided with the switch portion 61 at the end of the switch wiring 62 extending to the outside from the power strip housing 9 shown in FIG. 7 can be used properly according to the application. That is, in the state of the power strip 20, the switch unit 61 and the supply interruption circuit 42 (on the side of the power strip casing 9) are connected via a connector (jack 61j and plug 65p), while the connector is separated. Then, when the switch unit 61 is detached from the power strip housing 9, the switch wiring 62 is connected between them to be in the state of the power strip 30.

  More specifically, the power tap housing 9 is provided with a switch housing portion 65 for housing the switch portion 61, and a plug 65p and a jack 65j connected to the supply interruption circuit 42 are provided on the bottom surface thereof. . Further, a jack 61j is provided on the back surface of the switch unit 61, and the switch unit 61 is attached to the power strip housing 9 (stored in the switch storage unit 65) together with the connection to the plug 65p of the switch storage unit 65. On the other hand, in a state where the switch unit 61 is detached from the power strip housing 9, the plugs 62p at both ends of the switch wiring 62 are connected to the jack 61j of the switch unit 61 and the jack 65j of the switch storage unit 65, respectively. For example, a LAN cable can be used as the switch wiring 62. Further, each of the switch unit 61 and the switch storage unit 65 can be appropriately provided with an engagement unit for fixing the switch unit 61 during storage.

(Third embodiment)
A network device power strip according to a third embodiment of the present invention will be described with reference to the drawings. In the following, portions different from those of the first embodiment and the second embodiment will be mainly described, and overlapping portions will be denoted by the same reference numerals in the drawing and description thereof will be omitted. FIG. 12 shows an external perspective view of a power strip 40 according to the third embodiment. FIG. 14 shows the internal structure. The power tap 40 mainly includes a network monitoring circuit 7, a communication cable 71 extending from the network monitoring circuit 7, and a connection state display device 73. Note that the network monitoring circuit 7 corresponds to the network monitoring device of the present invention, and therefore the following description also serves as the description of the network monitoring device according to the embodiment of the present invention.

  As shown in FIG. 15, the network monitoring circuit 7 (network monitoring device 7) is configured as a normal microcomputer, and includes a well-known CPU 75, ROM 76, RAM 77, input / output interface (I / O) 78, and these configurations. A bus line 79 to be connected is provided. The CPU 75 performs control based on programs and data stored in the ROM 76 and the RAM 77. The ROM 76 has a program storage area 76a and a data storage area 76b. The program storage area 76a stores a network monitoring program 76p. The network monitoring program 76p operates on the RAM 77 in the form of using the work memory 77w as a work area. On the other hand, the data storage area 76b stores various data necessary for the operation of the network monitoring program 76p. These programs and data may be stored in an external memory. With the above configuration, the network monitoring circuit 7 functions as a connection monitoring unit and a reset signal output unit (signal output unit) when the network monitoring program 76p is activated by the CPU 75. FIG. 16 is a flowchart showing the processing of the network monitoring program 76p executed by the CPU 75.

  First, the network monitoring circuit 7 monitors the connection status with the Internet from inside the LAN (step S1, connection monitoring means). That is, the plug 71p at the tip of the communication cable (LAN cable) 71 is connected to one end of the switching hub 130, and the network monitoring circuit 7 is connected to the Internet via the network devices 110 to 130 connected to the outlets 1 to 3. The connection status is monitored by communicating with any external terminal. Monitoring of the connection status by communication with an external terminal can be performed, for example, by a technique such as ping (Packet Internet Groper) that transmits packet data and checks whether there is a reply. Then, packet data is transmitted at regular intervals, and when the reply is not received for a predetermined time or more, it is determined that the connection is in an intermittent state (step S2: Yes), and the process proceeds to steps S3 and S4.

  Next, the network monitoring circuit 7 switches the display of the connection status display device 73 that displays the connection status with the Internet (step S3, connection status display means). For example, as shown in FIG. 13, the connection state display device 73 has two lighting sections, one representing the connection state and the other representing the intermittent state. In addition, the connection state display 73 is configured such that the lighting unit is configured by an LED, for example, and the lighting is switched every time a pulse is input from the network monitoring circuit 7 by a flip-flop circuit or the like incorporated therein.

  Next, the network monitoring circuit 7 outputs a signal (reset signal) for interrupting the power input to the supply interruption circuit 42 (step S4, reset signal output means). As a result, the power supply to the network devices 110 to 130 connected to the outlets 1 to 3 is temporarily cut as described above, and then the power supply to the first to third outlets 1 to 3 is started by the operation of the supply delay circuit 43. The network devices 110 to 130 are collectively restarted while adjusting the timing of. In this way, the network monitoring circuit 7 automatically restarts the network devices 110 to 130 collectively when the connection with the Internet is in an intermittent state. After outputting the reset signal, the network monitoring circuit 7 returns to monitoring the connection state (step S1) after a predetermined time has elapsed. In the network monitoring device of the present invention, the signal output in this processing is not limited to the reset signal, and can be used for various purposes such as a signal for sounding an alarm.

<Network connection device>
A network connection apparatus according to an embodiment of the present invention will be described with reference to the drawings. In addition, about the location which overlaps with the above-mentioned network apparatus power supply tap, the same number is attached | subjected in a figure and description is abbreviate | omitted. FIG. 17 is a diagram schematically illustrating an internal configuration of the network connection apparatus 100. The network connection device 100 is a device that connects to the Internet while constructing a LAN in a house such as a detached house or an apartment house, and includes a line terminating device 110, a router 120, a switching hub 130, a power control circuit 4, and the like. A network monitoring circuit 7 is provided. Here, the network device power taps 10, 20, and 30 described above can be used for a portion corresponding to the power control circuit 4, and further, a portion corresponding to the power control circuit 4 and the network monitoring circuit 7. Can use the power tap 40 for network equipment described above.

  The line termination device 110 generally converts a signal transmitted through the communication line and an electrical signal to each other at the termination of the communication line from the external network. For example, at the end of a communication line such as an optical fiber cable connected to a line provider, an optical line terminator 110 (for converting between an optical signal transmitted in an optical fiber and an electric signal transmitted in a LAN) ONU: Optical Network Unit). This enables bidirectional signal transmission between the Internet and the LAN via a communication line such as an optical fiber cable, thereby realizing an always-on Internet connection environment. In addition, the communication line established between the line operator and the house is not limited to the optical fiber cable, but also a telephone line that realizes an ADSL (asymmetric digital subscriber line) connection service and a dedicated CATV connection service. A cable etc. can be mentioned. In this case, an ADSL modem or a CATV modem is used as the line termination device 110.

  The router 120 generally connects an external network and a LAN to each other and performs a relay process between them. The router 120 mainly has the following functions. The first is a function for connecting to the Internet. That is, a function as a PPPoE client that sends a user ID or password to an access server of a provider (ISP: Internet Service Provider) that performs connection service to the Internet for authentication, and a DHCP client that acquires setting information such as an IP address Have The second function is to manage access from outside. That is, it is a function that blocks illegal packets from the Internet by filtering or the like. The third function is to relay communication between the Internet and the LAN. This is the main function of the router 120, which corresponds to NAT or IP masquerading that mutually converts the global IP address assigned by the provider and the IP address used by the LAN terminal. The IP masquerade can share the number of IP addresses assigned by the provider and simultaneously access the Internet when there are a plurality of terminals. Fourth, it is a function for managing terminals on the LAN side. That is, it has a function as a DHCP server that automatically assigns an IP address of a terminal on the LAN side, and a function that acts as a proxy for accessing the DNS server.

  In addition, there are devices in which the above-described line termination device 110 and the router 120 are integrated and devices in which the switching hub 130 and the router 120 described later are integrated. In this case, since the line termination device 110, the router 120, and the switching hub 130 according to the present embodiment are combined, it can be suitably used for the configuration of the network connection device 100 of the present embodiment.

  The switching hub 130 (concentrator) is used as a branch device that constructs a LAN downstream of the router 120 so that electrical signals can be transmitted and received between the router 120 and the terminal. The switching hub 130 is also called a LAN switch, and is a line concentrator that bundles LAN cables and connects them in a star, and realizes a high-speed network environment. That is, data can be exchanged between terminals connected to the switching hub 130 and between the terminal and the router 120. An intelligent hub having a management agent function can also be used.

  In the above description, the wired LAN connection by the switching hub 130 has been described. However, the present invention is not limited to this, and a wireless LAN access point device that realizes a wireless LAN connection is used instead of the switching hub 130 according to the present invention. It can also be used as a device. The wireless LAN connection is slightly inferior to the wired LAN connection in terms of security, but has an advantage that there is no need to route a LAN cable in the house. Further, the switching hub 130 and the wireless LAN access point device can be used in combination.

  As described above, the supply delay circuit 43 adjusts the rising order of the line termination device 110, the router 120, and the switching hub 130. Further, the supply interruption circuit 42 is for restarting the line termination device 110, the router 120, and the switching hub 130 by interrupting the power input to the supply delay circuit 43 as described above. Here, the switch unit 61 is connected to the network monitoring circuit 7 via the switch wiring 62.
