DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for measuring a coordinate position of a device in a switchboard or a control panel or a coordinate position of a wiring route, calculating a length of a connecting wire, and further processing the wire based on the wire length data. In particular, the present invention relates to a wire length calculation device and a wire processing system for efficiently performing a connection wire processing operation in a panel.

[0002]

2. Description of the Related Art Conventionally, the wiring work of a switchboard or a control panel differs in the length of each wire and cannot be mass-produced. Measure the length of the electric wire from the terminal to the connection terminal of the connection, cut out the wire a little longer, actually lay the wire from the connection source to the connection destination along the wiring route, Excessive wires were cut to fit exactly. For this reason, an automatic machine such as an electric wire cutting device or a terminal crimping machine cannot be used, and an operator processes each wiring with a manual tool such as a nipper. On the other hand, a method of using a computer to calculate the wire length in advance has been considered. However, in order to calculate the wire length, it is necessary to read the terminal positions and wiring route positions of the connection source and the connection destination from various drawings and input them to a computer, and this data creation required a great deal of man-hours. .

[0003]

The above-mentioned prior art is concerned with accurately calculating the length of the electric wire required for wiring, in which three-dimensional data of the coordinate positions and wiring route positions of the source and destination appliance terminals are used. It needs to be created and input to a computer to calculate the line length. However, not all of these three-dimensional data are accurately illustrated in the installation drawing of the appliance, and it has been very difficult to prepare the data necessary for calculating the wire length. For this reason, a method of assembling an actual switchboard or control panel and then actually measuring the data and inputting the data to a computer has been adopted, which has been a work mode with low efficiency. On the other hand, since the data preparation man-hour required for calculation of the wire length becomes enormous, a method has been adopted in which the calculation of the wire length is stopped by a computer, and an operator performs a wiring work directly in a switchboard or a control panel.

SUMMARY OF THE INVENTION It is an object of the present invention to photograph three-dimensional mounting position data of equipment and a wire duct necessary for calculating the length of a wire by using a digital camera in an actual switchboard and measuring three-dimensional coordinates from the image. And to provide a mechanism that can calculate the wire length. An object of the present invention is that when a thick electric wire or a wiring route is complicated, an operator traces a wiring route from a connection source device terminal to a connection destination device terminal on a screen of a personal computer with a cursor. Another object of the present invention is to provide a mechanism for calculating a length of an electric wire required for wiring.

In order to achieve the above object, according to the present invention, the relative positions of the appliances and electric wire ducts in the panel are captured as image data by a personal computer by photographing the appliances and electric wire ducts mounted in the panel with a digital camera. By tracing the wiring route of the electric wire with a cursor on the screen in an interactive manner, the amount of change in the coordinate position is accumulated, and the value can be multiplied by an appropriate enlargement ratio to obtain the length of the electric wire. In order to achieve the above object, according to the present invention, wire length data, wire number mark data attached to both ends of a wire, and crimp terminal specification data are read into an automatic machine control device, and the wire length data is converted from the automatic machine control device to a wire cutting device.

By processing the electric wires according to the work instruction lights, it is possible to make electric wire processing systems with various commercially available automatic machines.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an overall configuration for making the present invention function. First, based on the sequence drawing 1, a wiring table 2 is prepared in which the wire numbers, the connection source and connection destination device numbers, the terminal numbers, and the wire specifications are described. However, at this time, the crimp terminal specification data of the wire length, the connection source and the connection destination has not been entered yet. The data of the wiring table 2 is input to the floppy 3 and further input to the personal computer 4.
Next, the arrangement state of the appliance 11 and the electric wire duct 12 inside the control panel 10 is photographed by the digital camera 6, and the image is taken into the personal computer 4. In the personal computer 4, the appliance number extracted from the wiring table 2 is displayed on the CRT screen, and the operator can interactively point the appliance on the screen of the personal computer 4 to calculate the coordinate position of the appliance. Specifically, a list (A1, A2, A3,... C3) of the appliance numbers used in the wiring table 2 is created inside the personal computer 4. Next, the image in the control panel taken by the digital camera 6 is arranged at an appropriate position on the screen of the personal computer. The operator calculates the coordinate position by pointing the attachment position of the appliance number read from the appliance list with the cursor on the personal computer screen. For example, when the connection source of the wiring table is A1, the coordinate position on the personal computer screen is determined by indicating the center position of A1 with a cursor, and the value is multiplied by an appropriate magnification to obtain the actual coordinate on the board. Can be converted to a value. FIG. 2 shows an example in which the image 17 of the digital camera is pasted on the development panel 13 in the control panel on the personal computer screen 18. Next, the position of the wire duct is measured. By specifying the front end 14 and the rear end 15 of the electric wire duct 12 displayed on the personal computer screen as shown in FIG.
2 can be measured. As described above, when the three-dimensional mounting position of the mounting device and the three-dimensional mounting position of the electric wire duct can be calculated, the length of the electric wire can be automatically calculated by adding the information of the wiring route thereto. However, the length of the electric wire calculated in this way is the length from the center position of the device, and the actual length of the electric wire needs to correct the distance from the center position of the device to the terminal position. For this purpose, a device master 5 in which the terminal position data of the mounting device and the mounting screw hole diameter of the terminal are registered in advance as a set of data is created, and the wire length according to the terminal position is corrected.
This is the actual wire length. Furthermore, when referring to the fixture terminal position from the fixture master 5, the size of the screw hole diameter of the crimp terminal used for connection of the terminal is read, and the length of the wire and the size of the crimp terminal attached to both ends of the wire are determined by a floppy disk. 20 is output.

The above method is a method of calculating the length of the electric wire from the three-dimensional data of the connection source device and the connection destination device, and the three-dimensional data of the wiring duct. Can be moved interactively, and the amount of movement can be converted to the length of the wire. First, as shown in FIG.

Further, the cursor is moved from the position to the position of the device terminal number of the connection destination on the personal computer screen along the path through which the electric wire passes. Personal computer is a personal computer screen 1
The moving amount of the cursor on the line 8 is sequentially integrated, and the integrated amount is multiplied by an appropriate magnification to convert the amount into the actual wire length. The specifications of the terminals are transcribed with reference to the device master 5 described above. The specification data indicating the wire length and the sizes of the terminals attached to both ends of the wire are added to the original data of the floppy 3 and output as the floppy 20.

The data table is composed of wire numbers, connection source device numbers, terminal numbers, connection destination device numbers, terminal numbers, and wire specifications. However, the columns of the wire length, the terminal specification of the connection source, and the terminal specification of the connection destination are initially blank. In these blank fields, the wire length data and the terminal specification data are additionally described by the operation method according to the present invention, and are taken out as the floppy 20. The collection of these data makes it possible to operate the electric wire processing system. Table 2 shows the data contents of the floppy 20.

The wire length data read by the automatic machine control device 21 shown in FIG. 1 is transmitted to the wire cutting device 22, where the wire is cut to a predetermined length and the coating is stripped. Next, the automatic machine control device 21 transmits the wire number data to the wire number mark printer 23, and the wire number mark is printed by the wire number mark printer 23.
The operator attaches the wire number mark to both ends of the wire. Next, the automatic machine control device 21 determines the size of the crimp terminals to be attached to both ends of the electric wire, and transmits a crimping instruction to the terminal crimpers 24, 25, and 26 equipped with the corresponding crimp terminals. The signal is transmitted to a crimping indicator light 34 attached to the terminal crimping machines 24, 25, 26,
Since the lights 35 and 36 are turned on, the worker can press the crimping indicator lights 34 and
After confirming the lighting state of 35 and 36, the tip of the electric wire is inserted into the terminal crimping machine where the work instruction lamp is lit, and the crimp terminal is attached. In the same manner, attach a crimp terminal to the rear end of the wire.
In this way, if the connection source device number changes to another device number while sequentially creating the connection wires, the automatic machine control device 21 determines that, and sends a bundle signal to the wire bundle machine 27. Send. The signal is output from a bundle indicator light 37 attached to the bundle machine 27.
Is turned on, the operator checks the lighting state of the bundle indicating lamp 37, and bundles the connecting wires into one bundle for each appliance number by the bundle binding machine 27. As described above, the wire length calculator and the wire processing system can be constructed.

Wire bundles 9 and 30 with different colors and thicknesses of wires are set. The electric wire cutting device 22 is provided with electric wire selection indicators 31, 32, and 33, which correspond to the electric wire hoppers 28, 29, and 30, respectively. Further, the wire specifications of the wire bundles set in the wire hoppers 28, 29, 30 are input to the automatic machine control device 21 in advance. In addition, the terminal crimping machines 24, 25, and 26 are provided with crimping instruction lights 34, 35, and 36, respectively, which are turned on by a command from the automatic machine control device 21. Terminal crimping machine 2
The terminal specifications of the crimp terminals set in 4, 25 and 26 are input to the automatic machine control device 21 in advance. In addition, the bundle binding machine 27 is provided with a bundle binding instruction lamp 37, which has a mechanism to be turned on by a command from the automatic machine control device 21. The floppy 20 including the specification data of the wire length and the size of the terminal to be attached to both ends of the wire is read into the automatic machine control device 21. First, the necessary wire type is determined from the wire specification data read into the automatic machine control device 21, the wire hopper in which the required wire type is set is determined, and the wire hopper corresponding to the wire hopper 28, 29, 30 is determined. One of the electric wire selection indicating lights 31, 32, 33 is turned on. The operator takes out the electric wire from the electric wire hopper where the electric wire selection instruction light is turned on and mounts the electric wire on the electric wire cutting device 22. The wire length data is transmitted to the wire cutting device 22 in a state where the wire is mounted, the wire is cut at a predetermined length, the coating is peeled off, and the wire material 40 for connection is created. Further, since the wire number mark is printed on the wire number mark printing machine 23, the worker attaches the wire number mark 41, then attaches the crimp terminals 42 to both ends of the electric wire, and finally, the bundling operation was described in FIG. In this way, the process is performed every time the connection source device number is changed, and finally, a connection wire bundle bundled by the bundle band 43 for each mounting device can be produced.

FIG. 4 is a completed view of one connection electric wire processed by the electric wire processing system of the present invention. The electric wire is cut and stripped by the electric wire cutting device 22 to become the connection electric wire material 40, the wire number mark 41 is printed by the wire number mark printing machine 23, and the wire is attached to both ends of the wire. Furthermore, crimping terminals 42 are attached to both ends by terminal crimping machines 24, 25, and 26 to form connection wires.

[0013]

According to the present invention, the wire length can be automatically calculated by the operator instructing the mounting position of the mounting tool and the mounting position of the wiring duct in an interactive manner. If the wire length can be calculated as described above, based on the data, it is possible to automate the length measurement cutting and stripping of the wire,
Further, by adding wire number data and screw hole diameter data of the crimp terminal, electric wires can be processed by various automatic machines.

[0014] In this manner, when the connection wires having the wire number mark and the crimp terminal attached to both ends of the wire are bundled and provided for each appliance, the wiring work in the control panel is performed by removing the crimp terminal at the end of the wire. The wiring can be completed by screwing to the terminal of the device, wiring the wire along the wiring path, and finally screwing the crimp terminal at the rear end of the wire to the terminal of the device. In addition, even if it is an insertion terminal instead of a screw terminal, if the terminal specification is clear, the same operation can be performed by replacing the terminal of the crimping machine with the insertion terminal. According to the present invention, it is possible to systematize electric wire processing using various types of commercially available automatic machines, thereby concentrating electric wire processing operations at one place and increasing productivity. Conventionally, wire processing and wiring work have been performed in a mixed manner, but since wiring work can be clearly separated into wire processing and wiring work, efficient wiring work can be performed. It has become possible.
