[0001]

FIELD OF THE INVENTION The present invention relates to systems and methods for creating network wiring diagrams.

[0002]

2. Description of the Related Art Conventionally, in order to create a network wiring diagram, a facility or manager of a network or a user who connects a device to the network is used to connect a facility of a communication cable or a device to the cable. After confirming the position of the information outlet and collecting the position information, the network wiring diagram was created by drawing or drawing equipment such as CAD.

Conventionally, as a system for acquiring information from a device provided at a required location of a network, Japanese Patent Laid-Open No. 08-08
As described in 305744, management information (burial date, pipe diameter, etc.) is stored, and a management tag having an information transmission function is attached to the required location (connection portion or branch portion) of the underground gas pipe. , A system for receiving management information from this management tag by a data collection device on the ground and inputting the received management information and position information of the data collection device to map data is disclosed.

Further, in Japanese Patent Laid-Open No. 05-30110, a transmitter is installed on a floor where network equipment is installed, or a transmitter is installed on the network equipment itself.
There is disclosed a system that detects a signal from a transmitter, collects installation position information of network equipment, and adds / updates the equipment layout information (floor layout diagram).

[0005]

However, in the above-mentioned conventional example, since the facility or manager of the network or the user who connects the device to the network confirms and collects the facility position of the cable and the position of the information outlet,
The position of cables and information outlets may not be collected correctly due to incorrect position confirmation or omission of confirmation, and may not be reflected correctly in the network wiring diagram.

When the positions of the cables and information outlets are frequently changed due to the addition, relocation, removal, etc. of the cables and information outlets, the positions of the cables and information outlets are checked and collected each time, and the network wiring diagram is handwritten. Alternatively, it is necessary to frequently rewrite and update by a drawing creation device such as CAD.

Further, Japanese Patent Laid-Open No. 08-3,083 described in the above-mentioned conventional example.
In the system described in 05744, since the position information attached with the management tag is detected by the data collecting device, it is necessary to move the data collecting device to the place in order to confirm and collect the position information. However, the location information could not be acquired easily.

Further, JP-A-05-3 described in the above-mentioned conventional example.
In the system described in 0110, the location information of the network equipment can be confirmed and collected, but the location information of the communication cable connecting the network equipment can be confirmed and collected.
Could not be collected. Further, the detected position information is to collect the position information of the floor on which the network equipment is installed, not the position information of the entire network.

The present invention is a network wiring diagram creating system capable of creating a network wiring diagram without a facility or manager of the network, or a user connecting a device to the network confirming and collecting the positions of communication cables and information outlets. And to provide a method.

Since it is attached to the terminal end 21 of, the identification number is "N-1-1-T". Since the transmitter 23 is attached not at the end of the communication cable 29 but at an intermediate position, its identification number is "N-1-2". Similarly, the identification numbers of the transmitters 24 to 28 are “N-1-3-
To "N-1-7-", and a unique identification number is given to each.

The transmitter 32 is driven by a battery (not shown) or is supplied with power from an attached communication cable or information controller.

FIG. 2D is an explanatory view of the receiver shown in FIG. 1, and the receiver 34 has a clock 35 and an automatic distance measuring device 36.
Is built in.

As mentioned above, the oscillator 3 shown in FIG.
2 has a built-in clock 33 and the receiver 3 shown in FIG.
The clock 35 built in 4 is completely synchronized.

Next, the operation of the first embodiment in the block configuration of FIG. 1 will be described with reference to the flowchart of FIG. Here, in order to simplify the description, the operation of one oscillator 11 connected to the communication cable 10 will be described. Further, it is assumed that three receivers 5 to 7 are fixedly attached to the ceiling or the pillar in the living room.

First, in step S301, the transmitter 11 attached to the communication cable 10 periodically has a unique identification number (for example, "N-1-1-T", which is represented by the four alphanumeric characters described above. )) To the receiver 7 installed in the living room. At that time, the time generated by the clock 12 built in the transmitter 11 is transmitted together with the identification number as the transmission time. In step S302, the receiver 7 receives the transmitter-specific identification number transmitted by the transmitter 11, and generates the time at which the identification number is received from the clock 9 incorporated in the receiver 7 to determine the reception time. get. Since the clock 12 built in the transmitter 11 and the clock 9 built in the receiver 7 are completely synchronized as described above, the difference between the transmission time and the reception time is used, and the receiver 7 receives the difference in step S303. The built-in automatic distance measuring means 8
The distance between the transmitter 11 and the receiver 7 can be measured. The receivers 5 and 6 also perform the same processing, and the automatic distance measuring means 14 and 1 incorporated therein, respectively.
3, the transmitter 16 and the receiver 5 by the clocks 16 and 15
And the distance between the transmitter 11 and the receiver 6 are measured. The distances from the transmitter 11 measured by the receivers 5 to 7 are transmitted to the automatic position detecting means 4 together with the identification number of the transmitter 11 in step S304.

Next, in step S305, the automatic position detecting means 4 draws a sphere whose radius is the transmitted distance centered on the position of the receiver 5, that is, the distance between the receiver 5 and the transmitter 11. Similar processing is performed for the receivers 6 and 7, and a sphere having a radius at each distance is drawn. As a result, the position of the transmitter 11 is specified at one point where the surfaces of the three spheres intersect, and therefore the position information of the transmitter 11 is calculated through the positions of the receivers 5-7.

The origin (x0, y0, z0) is a specific place in the living room where the receivers 5-7 are installed, and the position information of the receivers 5-7 is the origin (x0, y0, z
When expressed by the distance (xi, yi, zi) (i = 1 to 3) from 0), the calculated position information of the transmitter 11 is also the distance (xj, yj) from the origin (x0, y0, z0). , Zj)
It can be expressed in three dimensions (j = 1 to 3). By installing the receiver at three places and expressing the position information in three dimensions in this way, even if the communication cable is arranged three-dimensionally along a pillar instead of on the floor, it can be attached to the communication cable. It is possible to correctly calculate the positional information of the generated transmitter.

After that, in step 306, the automatic position detecting means 4 uses the calculated position information of the transmitter 11, for example (xj, yj, zj) and the identification number of the transmitter 11,
For example, "N-1-1-T" is transmitted to the automatic input means 3,
The automatic input means 3 transmits the transmitted positional information of the transmitter 11 and the identification number to the control means 1. In step 307, the control means 1 sends the position information of the transmitter 11 received through the automatic input means 3 to the living room layout information stored in the living room layout information storage means 2 to the transmitter 11.
Add with the identification number of.

The room layout information stored in the room layout information storage means 2 will be described with reference to FIG. The room layout information is acquired by the above operation and an area 501 for storing the positional information of the equipment / equipment previously installed in the room such as desks, chairs, pillars, and shelves in the room where communication cables and information outlets are installed. It is divided into areas 502 for storing the positional information of the transmitters. Further, the area 501 has an identification number storage area 501a for storing the identification number of the equipment / equipment and a position information storage area 501b for storing the position information thereof. Similarly, the area 502 stores the identification number of the transmitter. An identification number storage area 502a and a position information storage area 502b that stores the position information. The areas 501 and 502 may be continuous areas.

The position information of the transmitter 11 calculated by the above flow is additionally stored in the area 502b, and the identification number of the transmitter 11 is additionally stored in the area 502a.

In the case of representing a desk installed in a living room, for example, the identification number stored in the area 501a is composed of three alphanumeric characters such as "D-1-1", and the leading "D". Is a fixed identification code indicating a desk, the next "1" is a number unique to each desk, and the last "1" is a number indicating the position of the desk. One desk is "D-1-1",
It is represented by three identification numbers "D-1-2" and "D-1-3", and the last "1", "2", and "3" are "one side" when the desk is represented by a cube. The three positions of "corner", "other corner" and "height position" are shown. Then, as described above, the corner of the living room is set as the origin (x0, y0, z0), and the above three points are separated from the origin (x0, y0, z0) by the distance (x
i, yi, zi) (i = 1 to 3), and this distance is used as position information for each identification number in the area 501b.
Remember. In this way, the position of one desk can be specified. In the same manner, it is possible to specify the position information of the equipment / equipment already installed in the living room such as other desks / chairs / pillars / shelf.

By executing the operation shown in the flow chart of FIG. 3 for all the transmitters attached to the communication cable and the information outlet, the position information of all the transmitters is calculated and the living room layout information is calculated.

Determine if it is or is attached to an information outlet. This discrimination is realized by reading the symbol at the beginning of the identification number. If the symbol at the beginning is, for example, "N", this transmitter is attached to the communication cable, while if it is, for example, "C". For example, it is determined that the transmitter is attached to the information outlet. As a result, when it is determined that the transmitter is attached to the communication cable,
In step S403, lines are sequentially connected on the network wiring diagram based on the position information. As mentioned above, the identification number of the transmitter attached to the communication cable is
For example, it is expressed as "N-1-1-T", and the second number "1" is the number of the communication cable. Therefore, the second number of the acquired identification number of the transmitter is "1". By connecting the position information of the transmitter, a communication cable is created on the network wiring diagram.

On the other hand, in step S402, when it is determined that the information outlet is connected,
In step S404, a symbol indicating, for example, an information outlet is arranged on the network wiring diagram based on the position information.

An example of the network wiring diagram created in this way is shown in FIG. In this network wiring diagram, based on the position information of the desks, chairs, pillars, shelves, etc. in the living room that are input in advance in the area 501 of the living room layout information, for example, desks 601a, chairs 602a, pillars 603a The communication cable and the information outlet are acquired by the operation shown in the flowchart of FIG.
a-604d and information outlets 605a-605d are drawn on the network wiring diagram.

The network wiring diagram of FIG. 6 shows an example of a two-dimensional wiring diagram using only the two-dimensional coordinates of (x, y) in the position information of the living room layout information, but the coordinate in the height direction is added. It goes without saying that a three-dimensional wiring diagram using three-dimensional coordinates (x, y, z) can be created.

Furthermore, the created network wiring diagram is
The control means 1 displays on a display means (not shown),
It is also possible to output to an arbitrary output device such as printing out with a printer (not shown).

When a communication cable or information outlet is newly added, the position information of the transmitter is newly acquired by the above operation, and the position information and the identification number of the newly acquired transmitter are added to the living room layout information. And, consequently, a communication cable or information outlet is added on the network wiring diagram.

When the communication cable or the information outlet is moved, the position information of the new transmitter after the movement is acquired by the above operation and stored in the room layout information area 502a shown in FIG. The position information stored in the area 502b corresponding to the identification number of the moved transmitter is replaced with the newly acquired position information, and as a result, the position of the communication cable or the information outlet is changed on the network wiring diagram. It

On the other hand, when the communication cable or the information outlet is removed, the control means 1 is operated through the automatic input means 3.
