Abstract

PURPOSE:To save the space of the installation of an HUB within an office and to simplify the layout of the office by providing an alarm means notifying that a power source is interrupted by appealing to the ear. CONSTITUTION:The HUB is provided with a power source input part 1 supplying power supply to a repeater part 4, a stand-by power source 3, a switching means 2 to the stand-by power source and an alarm means 5 notifying that the power source is interrupted by appealing to the ear. When the power source of an HUB 6 is interrupted, the power source is immediately switched to the stand-by power source 3 by the switching means 2, the alarm means 5 operates by using the power source and the abnormality is notified to a user by sound. At this point, as the HUB 6 is incorporated in either one of a ceiling, a wall, a floor and furniture, the installation space of the HUB 6 within an office can be saved. Because many HUB 6 can be arranged by being preliminarily dispersed within the floor, the user can utilize the port of the HUB 6 within the space where he wants to utilize conveniently and the change of the layout of the office can be easily performed.

2. Description of the Related Art At present, LANs have become widespread in the information-oriented society, and their forms have become larger and larger. Conventionally,
The HUB, which is a network construction device, has been installed by various methods such as a wall hanging type, a rack storing type, and a desk setting type. For example, FIG. 3 shows an installation example of a desk-mounted HUB. In the figure, 6 is a HUB, 7 is a twisted pair wire, and 8 is a terminal. The HUB 6 operates as a multi-port repeater, and in addition to the terminal 8 shown in the figure, a plurality of terminals are generally wired around the HUB 6. In addition, a lower HUB may be cascade-connected to one HUB, so that the scale of the network can be expanded. HU like this
When the scale of the LAN using B advances, a large number of HUBs are required in the office to extend the communication distance, and a large space is required for installing the HUB. Also, the layout is frequently changed in the office, but if the HUB is moved every time, the layout change is troublesome.

On the other hand, when the power supply to the HUB is stopped and the HUB is stopped for some reason, the larger the LAN, the greater the influence on the network. With intelligent HUB,
While communicating, the user can recognize the abnormality of the HUB, but in the current LAN, many non-intelligent HUBs are still installed. Therefore, conventionally, an LED is attached to the HUB and the abnormality of the HUB is visually detected by the LED display. However, it is useless to attach the LED to the HUB installed in a place that is out of the user's view. Further, recently, a HUB having a small number of ports for constructing a small-scale network has been put on the market, but many of them use an external power source, and there is a fear that the function may be stopped due to the disconnection of the adapter section.

FIG. 1 is a block diagram of an embodiment of the present invention. In the figure, 1 is a power input section, 2 is switching means, 3 is a standby power source, 4 is a repeater section, and 5 is alarm means. The power input unit 1 supplies DC power from an external power source such as a power line wired under the floor. When the power supply from the outside is cut off, the switching means 2 switches to the standby power supply 3. As the backup power source 3, for example, a battery power source is used. The standby power supply 3 may have at least a capacity for operating the alarm means 5, but if the power supply capacity has a margin, the power supply to the repeater unit 4 can prevent the network from stopping. It is convenient. Next, as the switching means 2, for example, a relay circuit is used. This relay circuit includes, for example, a relay coil and a normally closed relay contact, and the relay coil is set to be excited by an external power supply. The relay contact is in the off state while the external power is supplied, and when the external power is cut off, the relay contact returns to the on state. As a result, the power supply from the standby power supply 3 to the alarm means 5 can be started. The repeater unit 4 is I
It realizes the function of a 10BASE-T multi-port repeater conforming to the EEE802.3 standard. The alarm means 5 is for aurally informing that the power supply has been cut off, and comprises, for example, an alarm buzzer. In addition, HUB
When 6 has a function of detecting an abnormality other than power interruption, it may be configured to notify an abnormality other than power interruption.

FIG. 2 illustrates the installation location of the HUB according to the present invention. In this installation example, the HUB 6 is installed under the floor, and the terminal 8 is installed on the desk. The HUB 6 and the terminal 8 are connected via a twisted pair wire 7. Twisted pair wire 7 is HUB6 using a modular plug etc.
Since the modular jack is detachable, when the terminal 8 is moved to another place, it can be easily reconnected to the HUB 6 installed in another place. In addition, as a place where the HUB6 is installed, other than under the floor,
It may be installed in the ceiling, embedded in the wall, or stored inside the furniture. By doing so, the installation space in the office can be reduced as compared with the conventional system in which the HUB is installed on the desk as shown in FIG.

According to the present invention, the HUB is installed on the ceiling, the wall,
Since it is installed on either the floor or the furniture, it has the advantage of saving the installation space of the HUB in the office, and many HUBs can be distributed in advance on the floor. The HUB port in the space you want to use can be easily used as if you were using a power outlet, and you can easily change the office layout. Further, by providing the HUB with the alarm means by sound, even when the HUB is installed outside the user's field of view, the installation location can be easily and quickly known, so that the network can be quickly recovered. further,
By providing the standby power supply, it is possible to secure a power supply for operating the alarm means even when the power supply to the HUB is cut off, and if the power supply capacity has a margin, the repeater unit can also be operated by the standby power supply, so that the network This has the effect of preventing downtime.
