Abstract

PURPOSE:To operate a switch independently with an operation in each group by providing a local controller with group classifications managing a relevant group independently in a wiring cable at every group. CONSTITUTION:A local controller 22 is introduced to groups No.2-No.n respectively for controlling a wiring cable 11 among groups No.1, No.2-No.n. Each local controller 22 consists of a communication control unit(CCU) 31, a data terminal equipment(DTE) 32 and a filing device 33. When the setting change of a switch is desired, the resetting information is once stored in the filing device 33 and sent to switch control line 18 through the equipment 32 and the unit 31 as switch open/close information SI. A communication control unit(CCU) 34 in a center controller 21 sends the information to a central processing unit(CPU) 35, where the information is subjected to reception processing and the processing result is stored in a file device 36.

Description

[Detailed Description of the Invention] [Summary] A plurality of information outlets are inserted in series into a loop-shaped distribution cable and each corresponding terminal device is connected to a desired conductor in the distribution cable via a switch. and a center control device that commonly controls the opening and closing of a desired switch for all the information outlets inserted into each of the plurality of wiring cables, and a central control device that controls opening and closing of the switch. A plurality of local control devices are provided for each wiring cable individually, and when switch opening/closing information is input from one local control device,
The center control device receives this and controls opening and closing of the switch.

[Industrial application field]

The present invention relates to a wiring device, and particularly to a wiring device for wiring signal lines of distributed terminal devices.

With the recent trend toward office automation, a large number of various terminal devices have been introduced into office buildings and the like. Since these terminal devices are connected to each other or to external terminal devices by signal lines, a considerable amount of signal lines are laid out on the office floor.

The present invention refers to wiring devices for these signal lines.

[Conventional technology]

Conventionally, efforts have been made to route signal lines of a large number of terminal devices efficiently and without spoiling the aesthetic appearance. A typical example is an undercarpet type wiring device that is widely applied to the floors of office buildings. This is pre-wiring signal lines for each terminal device under the carpet. This allows signal lines to be laid freely without spoiling the aesthetics of the office floor.

However, in the above-mentioned undercarpet type wiring device, the degree of freedom in changing the wiring layout is extremely low, and the cost of removing the carpet and rewiring is considerably high. For this reason, running costs are high in offices that undergo frequent redecoration.

Therefore, the applicant prototyped the following wiring device. The present invention is based on this wiring device.

FIG. 7 is a diagram showing an outline of a wiring device forming the premise of the present invention. In the figure, reference numeral 11 denotes a wiring cable, which is wired in a loop throughout the cable via a plurality of distributed terminal devices (T11 and 16).

The distribution cable 11 consists of a multicore conductor 12 (part of the distribution cable 11 is shown in cross section).

Information sockets 13 are inserted in series with the wiring cable 11 to correspond to each terminal device. Each information outlet 13
The matrix switch unit 14 selectively connects the corresponding terminal device 16 and the desired conductor 12 of the wiring cable 11 via the corresponding switch, and the matrix switch unit 14 selectively connects each switch in the matrix switch unit 14. It is composed of a control unit 15 that controls opening and closing. The matrix switch unit 14 and the corresponding terminal device 16 are connected by a signal line 17.

[Problems to be Solved by the Invention] The wiring device shown in FIG. 7 has problems that need to be solved in practice. That is, changing the wiring device, for example, installing a new terminal device 16, installing a new information outlet 13 due to expansion,
When the settings of the switches in the matrix switch unit 14 need to be changed due to an expansion or a change in the terminal equipment 16, the settings of the switches in the matrix switch unit 14 must be easily performed.

Therefore, an object of the present invention is to provide a wiring device that can easily set the opening and closing of switches in a matrix switch unit from the outside.

[Means to solve the problem]

FIG. 1 is a diagram showing the basic configuration of a wiring device according to the present invention. It should be noted that the same components are designated with the same reference numbers or symbols throughout the plan. In this figure, 21 is a center control device, preferably a switching equipment (PBX) 2
It is provided on the 0 side. 22 is a local control device;
Multiple groups (n groups NILI-Na in the figure)
Wiring cable 1 divided into
1.

[For production]

The center control device 21 controls a plurality of groups (Sou 1-Na
For each of the distribution cables 11 classified into n), a control command CC is commonly sent to all control units 15 arranged in each distribution cable 11 through each switch control line 18. With this control command CC,
It is possible to open and close the switches in all the information outlets 13 under the PBX.

On the other hand, wiring cable 1 for each group (Magic 1-Nan)
A local control device 22 for each group individually manages all the control units 15 arranged in one group. This local control device 22 cannot control opening/closing of switches in its own group as well as switches in other groups.

It simply transmits the switch opening/closing information Sl to the switch control line 18 when a switch opening/closing request occurs within its own group. The reason why each local control device 22 is intentionally not allowed to control the opening and closing of the switch is to avoid logical contradiction with the switch opening and closing control from the center control device 21.

Normally, if there is a central control device 21 placed under a building manager or the like, there is no need to individually control the opening and closing of switches by placing them in the local control device 22 for each group. However, for example, if each group is each tenant in an office building, there will be a demand for opening and closing switches independently by operations within each group. In other words, there is a desire to eliminate the hassle of having to submit a connection change notification to the building manager to change the switch connection. The wiring device of the present invention can meet this demand.

〔Example〕

FIG. 2 is a diagram showing an embodiment of the present invention. In this diagram,
Distribution cables 11 of groups No. 1, Nα2 and No.n are shown, and Nα2 and No.
An example is shown in which local control devices 22 are introduced into groups n. Both the local control devices 22 and the center control device 21 basically consist of the same hardware,
Each local control device 22 is a communication control device (CCII) 3
1, a data terminal equipment (DTE) 32, and a file device 33. The file device 33 is composed of, for example, a floppy disk device, and holds data regarding the open/closed states of switches within its own group. When you want to change the switch settings, first save the settings change information to file device 3.
3 and transmits it to the switch control line as switch opening/closing information Sl through devices 32 and 31. In the figure, the switch control line is indicated by a dashed line 18.

The communication control unit 2 (CCU> 34 in the center control device 2I, which received this switch opening/closing information St via the terminal 37' in the switchboard 37, passes it to the central processing unit (CPU) 35, where it is sent to the central processing unit (CPU) 35. After receiving and processing, it is stored in the file device 36. This file device 36 stores all the information outlets 1 under the exchange (PBX) 20.
3. Hold the switch in the open/closed state. The information 31 received now is temporarily stored in the file device 36, and a control command is sent from the central processing unit 35 to the control unit (15 in FIG. 1) in the information outlet 13 via the switch control line 18. Send CC. Based on this command CC, the corresponding switch is controlled to open and close. This switch control line 18 is connected to a jack (
It is connected to each communication control device 31 via a so-called modular jack (usually) 38. Another type of jack is 39
These jacks are shown in Figure 39, showing four examples.
is for connecting each corresponding terminal equipment (TE) 16 and the PBX 20.

Figure 3 shows the schematic structure of one group.
An arbitrary group in FIG. 2 is extracted.

An example of four information outlets is shown, and only the information outlet 13 to which the local control device 22 is attached is specifically shown, and the matrix switch unit 14 and control unit 15 described above are illustrated. The present invention is particularly advantageous when wiring cables 11 consisting of a plurality of groups are wired, but it is basically applicable even to a wiring device having only one group as shown in this figure.

), and each is expressed in words in the area in which it is executed (each area of the local control device 22, center control device 21, and information outlet 13). Note that various means can be considered for starting communication between each local control device 22 and the center control device 21, but one is that the local control device 22 whose switch settings are to be changed is connected to the PBX 2.
Center control unit by dialing using 0! 2
1, and the other is the center control device 2.
One possible method is to sequentially poll each local control device 22 and call the center control device 21 in accordance with the polling timing.

FIG. 5 shows a specific example of the control unit and its surrounding circuitry. In this figure, the information outlet 13 is composed of a matrix switch unit 14 and a control unit 15, and this control unit 15 includes a processor section 41, a switch control section 42, a self-address holding section 43, and a storage section 44. A processor section 41 consisting of
is connected to the central processing unit (CPU) 35 of the center control device 21 via a switch control line. In practice, an interface 46 is provided.

The processor unit 41 in each information outlet 13 receives the control 8 command CC from the central processing unit 35 via the switch control line 18 . Switch control wire 18 is preferably incorporated into one of the conductors 12 within distribution cable 11 .

The switch control unit 42 controls opening and closing of each switch in the matrix switch unit 14 based on a command from the processor unit 41.

Among the many switches arranged in a matrix, the switch corresponding to the intersection point is closed in order to connect to one or more conductive wires required by the terminal device 16. Other switches not related to network establishment are left open.

Since the central processing unit 35 is commonly connected to all the information outlets 13 through one switch control line 18, when transmitting, the address specifying the destination is sent to the control command C.
Add to C. This address is allocated in advance to each information outlet 13, and is held by the self-address holding unit 43. It detects that the control command CC addressed to itself has been transmitted by checking whether there is a match with the address from the central processing unit 35, and notifies the processor section 41 that the transmission has been made. Thereafter, the received switch opening/closing information is stored in the storage section 44.

The processor section 41 instructs the switch control section 42 to control the opening and closing of the switches in the switch unit 14 according to the switch opening/closing information stored in the storage section 44 .

FIG. 6 is a diagram showing a specific example of a matrix switch unit, and in this figure, LFI to LF24 are those wired to the left side of each information outlet among the conductors 12 of the above-mentioned wiring cable 11, and RFI to LF24.

When passing through the information outlet 13, for example, use a conductor (
The relay contacts connected to LF4-RF4) are both closed, and the relay contacts in the middle, which intersect with the lead lines to the modular jacks MJI-MJ4, are open. On the other hand, for example, when it is desired to connect the conducting wire (LF7-RF7) to the modular jack MJ3, both the relay contacts corresponding to LF9-RF9 are closed, and the relay contact located between them is also closed.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to centrally control the opening and closing of the switch group in each information outlet using commands from an external computer, and also independently control the opening and closing of the switch group in each information outlet without conflicting with the computer. Opening/closing commands can be given to switches within a group.
