[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wiring and piping for communication cables and power cables, wiring for various lines such as piping for gas, water and sewage, air, and steam pipelines, and wiring / piping for calculating the length of the piping. The present invention relates to a length calculation device.

[0002]

2. Description of the Related Art Conventionally, in the design work of wiring, piping, etc. in a building, the work of calculating the wiring or piping cable length basically depends on a human. Therefore, an outline of the conventional cable length calculation work will be described. First, the number of devices such as telephones and terminals installed on each floor of the building is calculated, and based on this information, the number of wiring boards to be installed in the building and its installation location are determined. Next, based on these design information, the construction engineer uses a word processor, CAD (Computer Aided Design), etc., or a special application program that automatically creates a system diagram from the above design information. , Was building a systematic diagram of the building. When performing the cable length calculation work, the person in charge of construction consults the electronic desk calculator (so-called calculator) or commercially available spreadsheet software, etc., referring to the building system diagram created in advance as described above. The length of the cable to be wired between the building facilities was calculated by checking the height of each floor of the building and the place where the wiring board was installed.

[0003]

By the way, the system diagram creation program uses various information such as the number of floors and floor heights of buildings, the number of wiring boards, and the installation location, and calculates the wiring and piping cable lengths for these. It contained enough information to do so. However, conventionally, the cable system diagram is created and the cable length is calculated independently, and the information referred to in the system diagram creation program cannot be effectively used for the cable length calculation work. It was for that reason,
For example, it is necessary to calculate the cable length based on the changed building system diagram every time the design is changed due to customer's request. However, the work of calculating the cable length depends largely on humans, and if the building becomes large or the wiring inside the building is complicated, this work will take a lot of time, and It was not possible to improve work efficiency.

The present invention has been made in view of the above points, and an object thereof is to calculate wiring / pipe lengths in the process of making a line system diagram by an operator using a computer. It is to provide a possible wiring / pipe length calculation device.

ate Branch eXchange (private branch exchange) 1 is the starting point for star-shaped wiring in the building premises. An MDF (Main Distributing Frame; main wiring board) 2 installed in a machine room or the like is connected to the end of the PBX 1.

Each floor of the building has a floor IDF (Intermed
iate Distributing Frame (intermediate wiring board) 3 is installed,
It is possible that a plurality of floor IDFs 3 are installed on each floor. That is, the building is provided with an EPS (Electric Pipe Space) that is a space for passing an electric power line and a telephone line, and the number of EPSs is called "the number of systems". A unique number is assigned to each system corresponding to EPS, and system 1, system 2, ...
..., etc.

The MDF 2 and each floor IDF 3 are connected by a trunk cable 4. An indoor IDF5 may be connected to the floor IDF3 depending on the building form. From the floor IDF 3 or the indoor IDF 5, a number of outlets 7 which are information outlets are connected via floor branch cable 6. A telephone or various terminals (telephone terminal, data terminal, etc.) is connected to the outlet 7 via a cord or a terminal code. In the following description, MDF2,
The floor IDF3 and the indoor IDF5 are collectively referred to as DF (wiring board).

FIG. 2 is a block diagram showing a configuration example of the wiring / piping length calculation device according to the present embodiment, which can be constituted by a general personal computer or workstation. In the figure, a control device 11 corresponds to a microprocessor or the like and controls the entire wiring / pipe length calculation device. The display device 12 is, for example, a CRT (Ca
thode Ray Tube), liquid crystal display, key input device 1
Reference numeral 3 is, for example, a keyboard, pointing device 14 is, for example, a mouse, trackball or pad, and output device 15 is, for example, a printer.

The storage device 16 is a general memory composed of elements such as a RAM (random access memory) and is logically divided into a program memory 17, a file memory 18 and a data memory 19. Although illustration is omitted, the storage device 16 also stores an operating system, a driver, and the like necessary for the operation of the computer.

The program stored in the program memory 17 controls the operation of the wiring / pipe length calculation device, and the control device 11 follows the control of these programs.
Various processes described below are executed. Program memory 17
Details of the functions of the cable length calculation program 17a and the system diagram creation program 17b therein will be clarified in the description of the operation. It is possible to create a detailed system diagram of the building by the system diagram creating program 17b. However, in the following, only the part related to the present invention (that is, the DF and the cable connecting the DFs) will be described. And The facility information file 18a stores facility information such as PBXs, DFs, outlets, and terminals installed in the building as workers such as construction workers create a system diagram of the building.

The floor height table 19a stores the height of each floor of the building as shown in FIG. In the case of a normal building, all the floor heights are the same, but for convenience of explanation, the floor heights of the buildings are all different in the figure. As shown in FIG. 4, the inter-system distance table 19b stores building inter-system distances for all combinations of systems.
As shown in the figure, the result obtained by adding the inter-system distances of 2 to 3 systems to the inter-system distance of 1 to 2 systems is not equal to the inter-system distance of 1 to 3 systems. In the horizontal pull length table 19c, the horizontal pull length that means the distance from each DF (MDF, floor IDF, indoor IDF) to the EPS is D.
Stored for each F.

The connection point table 19d stores position information corresponding to an operation performed by a worker in the process of creating a building system diagram. In this embodiment, the "floor number" of the building and the "system number" of the building system are used as the position information. In creating a system diagram, an operator arranges equipment such as DF on the screen by using the pointing device 14 while looking at the display screen of the display device 12, and connects the arranged DFs with a cable. And so on. that time,
To connect the DFs, as shown in FIG. 6, the cables are complicatedly routed across the floors of the building and between the systems. Along with this, the worker connects the connection points P1 to P1 shown in FIG.
P10 will be specified. And placed D
The position information of the connection point designated as F is the connection point table 1
It will be sequentially stored in 9d.

On the other hand, the recording medium 20 is any one of the various recording media described above, in which a cable length calculation program 17a and a system diagram creation program 17b are stored. These programs are read into the storage device 16 via the drive device 21 such as a floppy drive device or a CD-ROM drive device. Then, data transmission via the common bus BUS is performed between the respective units of FIG. 2 described above. If the program memory 17 is composed of a ROM (Read Only Memory) or a non-volatile memory and the cable length calculation program 17a and the system diagram creation program 17b are stored in advance, the recording medium 20 is not used. Morphology is also conceivable.

Next, referring to the flow chart of FIG.
The operation of the wiring / pipe length calculation device having the above configuration will be described. First, in step S1, the outline of the building is drawn on the display screen of the display device 12. Therefore, the control device 11 activates the system diagram creation program 17b. As a result, the control device 11 accesses the equipment information file 18a, acquires the top floor, the bottom floor, and the number of systems of the building and stores them in the data memory 19, and then based on these information, the exterior shape of the building. To draw. Since the details of this drawing process are not directly related to the present invention, the details are omitted here.

Next, in step S2, the operator is made to input the minimum necessary information for the calculated cable length. These pieces of information are the floor height of the building, the distance between systems, and the horizontal pull length. Therefore, the control device 11 uses the cable length calculation program 17a.
To start. It should be noted that, of the processing executed by the control device 11 hereafter, this will be indicated only when controlled by the system diagram creation program 17b, and not when controlled by the cable length calculation program 17a. Now, the control device 11 reads the information of the top floor, the bottom floor, and the number of systems stored in the data memory 19 of the building. Here, in the following description, the uppermost floor is the fifth floor, the lowermost floor is the first basement floor (B1), and the number of systems is 3 (system 1 to system 3). As for DF, as shown in FIG.
There are two units, the floor IDF3a and the floor IDF3b .

Next, the control device 11 causes the display device 12 to sequentially display screens for prompting data input. The data input items displayed by the control device 11 are the floor height of each floor from the bottom floor to the top floor, the inter-system distance regarding three combinations of the systems 1 to 3, and the lateral pull length for each DF. The operator sequentially inputs the value of the item from the key input device 13 according to the instruction content on the screen. Accordingly, the control device 1
1 is the floor height table 19 for each input data
a, inter-system distance table 19b, horizontal pull length table 19
Store it in c. By the series of processes, the contents of each table are as shown in FIGS. 3 to 5, for example.

Next, in step S3, the operator uses the pointing device 14 to specify the arrangement of the DFs and how to route the cables between the DFs while looking at the outer shape of the building drawn on the display device 12. First, the worker arranges the MDF 2 shown in FIG. That is, the operator uses the pointing device 14 to instruct "to place the MDF from now" using a menu or the like (not shown) on the screen, and then moves the pointer PT to the position of MDF2 in FIG. The arrangement of the MDF 2 is confirmed by clicking the button of the dating device 14. Next, after the operator gives an instruction to “pull the cable around”, the pointer PT is sequentially moved to each position of the connection points P1 to P10, and the button of the pointing device 14 is clicked to connect these points. Specify the position of each. Finally, the floor IDF 3a is arranged in the same procedure as the MDF 2.

On the other hand, the control device 11 determines whether the DF is arranged or the connection point is specified in accordance with the operation of the operator, and the pointer P at the time of button click.
Based on the position of T, position information (that is, floor number and system number) of the position is determined. For example, if MDF2 is arranged, the control device 11 sets the MDF as the DF name.
2. Calculate the basement floor as the number of floors and 1 as the system number. Further, if the connection point P2 is designated, the control device 11 calculates the first floor as the floor number and 2 as the system number. Then, the control device 11 sequentially stores the calculated position information in the connection point table 19d. On the other hand, the control device 11 is controlled by the system diagram creation program 17b.
The pointers PT at each time when the button is clicked are connected by a straight line in accordance with the operation of the operator. As a result, as shown in FIG. 6, MDF2 → connection point P1 → connection point P
2, ..., → Draw the wiring corresponding to the cable on the system diagram like floor IDF3a.

Next, in step S4, the controller 11
After initializing the cable length to "0", the cable length is obtained by the following procedure. That is, the control device 11 sequentially extracts information about two adjacent connection points from the beginning of the connection point table 19d. Next, the control device 1
1 determines whether or not the number of floors or system numbers are different between these adjacent connection points, and executes one of the following four types of processing according to the combination of these differences.

When the floor numbers are different and the system numbers are the same (step S5). By referring to the floor height table 19a, the floor height difference is calculated based on the floor height of each floor existing between the floors of adjacent connection points, and this is added to the cable length. If the system numbers are different and the floors are the same (step S
6). The inter-system distance corresponding to each system number of the adjacent connection point is read from the inter-system distance table 19b and added to the cable length. However, when the DF name of any of the connection points is "MDF", the inter-system distance is regarded as "0". In this case, therefore, the inter-system distance is not added. Then, whether or not each connection point is a DF (MDF, floor IDF, or indoor IDF) is determined by the DF name. If the connection point corresponds to DF, the horizontal pull length table 19
Referring to c, the horizontal pull length corresponding to the DF name is acquired and added to the cable length.

When both the floor number and the system number are different (step S7) In this case, as shown in FIG. 8, this corresponds to the operator designating the wiring diagonally. Therefore, in this case, a message "Cable length cannot be calculated" is displayed on the display device 1.
2 is output and the calculation processing of the cable length is stopped. When both the floor number and the system number are the same (step S8) In this case, assuming that the cable length is "0",
Cable length addition processing is not performed.

Next, in step S9, the control device 11
By determining whether or not the cable lengths have been calculated for all the adjacent connection points, the process of step S4 is performed for all the connection points stored in the connection point table 19d. Finally, in step S10, the control device 11
Displays the final cable length on the display device 12, or
Alternatively, it is output to the output device 15.

Now, in the following, the connection point table 1 of FIG.
The cable length calculation process performed in steps S4 to S9 will be described along with the content of 9d. First, in the case of MDF2 to the connection point P1, only the system number is different, so 30 m is obtained as the inter-system distance of system 1 and system 2. However, since the first connection point is the MDF, the inter-system distance is regarded as “0” and the inter-system distance is not added to the cable length.
Only the horizontal pulling length of 10 m is added to the cable length. next,
In the case of the connection points P1 and P2, only the number of floors is different, so the floor height 6m of the first basement floor is added to the cable length as the floor height difference from the first basement floor (connection point P1) to the first floor (connection point P2). .

Next, in the case of the connection points P2 to P3, since the floor number and the system number are the same, the cable lengths are not added. This also applies to the connection points P3 to P4.
Next, in the case of the connection points P4 to P5, only the system numbers are different, so the inter-system distance 20 m of the systems 2 to 3 is added to the cable length. Next, in the case of the connection points P5 to P6, since only the number of floors is different, the floor height of the first floor to which the connection point P5 belongs is 5 m.
Is added to the cable length. This also applies to the connection points P6 to P7, and the floor height of the second floor to which the connection point P6 belongs is 3
Add m to the cable length.

Next, in the case of the connection points P7 to P8, since only the system numbers are different, the distance 20 between the systems 2 to 3
Add m to the cable length. This is the connection point P8-P9
In the case of, the same applies, and the inter-system distance of 30 m for system 1 and system 2 is added to the cable length. Next, connection point P9
In the case of ~ P10, since only the number of floors is different, the connection point P9
4m + 7m = 11m from the 3rd floor to which the connection point belongs to the 5th floor to which the connection point P10 belongs is added to the cable length. next,
In the case of the connection point P10 to the floor IDF 3a, since only the system number is different, the system distance 25m of the systems 1 to 3 is added to the cable length. Further, since the second connection point is DF, the horizontal pulling length of 7 m of the floor IDF 3a is added to the cable length. Then, the calculation processing of the cable length is completed up to this point.

In the above description, the worker inputs the floor height of the building, the distance between systems, and the lateral pulling length. However, if the values of these pieces of information are known in advance, these pieces of information may be included in the equipment information file 18a, and these pieces of information may be expanded on the data memory 19 before the cable length is calculated. good. Further, in the above description, the calculation of the cable length in the building is given as an example, but it goes without saying that the same can be applied to the calculation of the lengths of the pipes and the wirings in the various lines such as the above-mentioned water supply and sewerage systems. Further, in the above description, MDF2
After arranging, the connection points are sequentially specified, and finally the floor IDF 3a is arranged. However, these arrangements and designations may be performed in any order, that is, from the final system diagram shown in FIG. 6 to FIG.
Anything that can create the connection point table shown in FIG.
