Further, when the antennas 5B ₂ , 5B ₃ and the antennas 5C ₂ , 5C ₃ receive response signals from the respective IC tags 3A as electromagnetic waves, the response signals are reproduced from the electromagnetic waves and sent to the wire management computer 6.

  The electric wire management computer 6 performs processing such as measuring the number of the electric wires 3 drawn out from the electric wire drum 2 or the electric wires 3 returned to the electric wire drum 2 based on the response signal from the read / write device 5. As shown in FIG. 5, an interface 6A, an input unit 6B, a processing unit 6C, a storage unit 6D, a transmission / reception unit 6E, and a display unit 6F are provided. The interface 6A exchanges various signals between the control unit 5D and the processing unit 6C of the read / write device 5.

The storage unit 6D stores processing procedures for various processes of the processing unit 6C.

  The processing unit 6C performs various processes related to the electric wire 3 according to the processing procedure stored in the storage unit 6D. When the processing unit 6C receives an instruction from the input unit 6B indicating the start of the withdrawal quantity management process associated with the withdrawal of the electric wire 3, the processing unit 6C starts the process illustrated in FIG. The processing unit 6C sends an inquiry signal to the interface 6A (step S1). Thereafter, the processing unit 6C determines the presence / absence of a response signal from the signal reception state by the interface 6A (step S2). If it is determined in step S2 that the interface 6A has not received a response signal, it is determined whether or not the inquiry signal has been transmitted from the interface 6A to the read / write device 5 a predetermined number of times (step S3). In step S3, if the inquiry signal has not been transmitted a predetermined number of times, the process returns to step S1, and if the inquiry signal has been transmitted a predetermined number of times, it is determined that the drawing operation of the electric wire 3 has been completed (step S4). The process is terminated.

If it is determined in step S2 that the interface 6A has received the response signal from the read / write device 5, the processing unit 6C receives the response signal from the interface 6A (step S5), and extracts the order information from the response signal (step S6). The processing unit 6C determines whether or not the N pieces of order information extracted in step S6 are adjacent and continuous (step S7). In this embodiment, since the read / write device 5 has four antennas 5B ₂ and 5B ₃ and antennas 5C ₂ and 5C ₃ , the value of N is 4. When the order information is continuous, the processing unit 6C determines that the electric wire 3 is being pulled out (step S8), and returns the process to step S1.

If N pieces of order information are not continuous in step S7, that is, only order information from two response signals read by the two antennas 5B ₂ and 5B ₃ provided in the first antenna unit 5B of the read / write device 5 is provided. Are consecutive, the processing unit 6C determines that the electric wire 3 has been cut (step S9). After step S9, the processing unit 6C, the antenna 5B ₃ response signal read in the first antenna portion 5B, that is, the response signal acquired from the IC tag 3A on the front end portion of the electric wire 3 of the wire drum 2 side The use quantity which is the length of the cut | disconnected electric wire 3 is calculated using the included order information (step S10).

In step S <b> 10, the processing unit 6 </ b> C calculates the usage amount of the lead wires 3 as follows. As shown in FIG. 7, the order information stored in the IC tag 3 </ b> A at the beginning of the electric wire 3 wound around the electric wire drum 2 is the number “T ₁ ”, which is a young number. Thereafter, the numbers increase in order, and FIG. 7 illustrates numbers “T _n−2 ” to “T _{n + 3} ”. Here, when the electric wire 3 is cut between the number “T _n ” and the number “T _{n + 1} ”, the drawn out electric wire 3 is moved for laying work and remains in the read / write device 5. Is the tip of the electric wire 3 wound around the electric wire drum 2. At this time, the numbers read by the first antenna unit 5B of the read / write device 5 from the IC tag 3A on the distal end side of the electric wire 3 are “T _{n + 1} ” and “T _{n + 2} ”, and the processing unit 6C Using the number “T _{n + 1} ” on the tip side,
(T _{n + 1} −T ₁ −1) · D
Is calculated. This calculation result is the length of the drawn wire 3, that is, the length of the wire 3 from the IC tag 3A with the number “T ₁ ” to the IC tag 3A with the number “T _n ”. It is a quantity.

After step S10, the processing unit 6C stores the used quantity of the lead wire 3 as a calculation result in the storage unit 6D (step S11). The processing unit 6C stores product information contained in the response signal acquired from the antenna 5B ₃ of the first antenna portion 5B in the storage unit 6D (step S12). After step S12, the processing unit 6C returns the process to step S1. In this way, the processing unit 6C performs a drawing quantity management process associated with the drawing of the electric wire 3.

The processing unit 6C performs the next writing process after the withdrawal quantity management process. When a write instruction for the electric wire 3 is input to the input unit 6B, the processing unit 6C reads the usage amount of the electric wire 3 stored in the storage unit 6D, controls the interface 6A, and controls the read / write device 5 A write signal for recording the used quantity is sent to the antenna 5B ₃ of the one antenna unit 5B. Thereby, the antenna 5B ₃ of the first antenna unit 5B records the used quantity on the IC tag 3A on the tip end side of the electric wire 3 from the electric wire drum 2.

  The processing unit 6 </ b> C performs the next transmission process after completing the drawing quantity management process for the wires 3. When a transmission instruction for the host computer 9 is input to the input unit 6B, the processing unit 6C reads the used quantity and product information stored in the storage unit 6D, controls the transmission / reception unit 6E, and passes through the communication network 100. Then, the used quantity and product information of the lead wire 3 are transmitted to the host computer 9. Further, when work content for the electric wire 3 is input to the input unit 6B during the transmission process, work information representing the work content is also sent to the host computer 9.

  As described above, the processing unit 6C performs various processes including the amount management process for the number of drawn wires 3 according to the processing procedure stored in the storage unit 6D. There is. The return of the electric wire 3 is performed when the laid electric wire 3 is removed. When the processing unit 6C receives an instruction from the input unit 6B indicating the start of the return quantity management process associated with the return of the electric wire 3, the processing unit 6C performs the same process as the drawn quantity management process of the electric wire 3. However, in this management process, the process of step S8 in FIG. 6 is read as “determining that the electric wire is being inserted”, the process of step S9 is read as “determining that the end of the electric wire is reached”, and the process of step S10 is changed to “ "Calculate the length of the wire that has been put back in." By this return amount management process, the processing unit 6C stores the return amount and product information of the return wire 3 in the storage unit 6D in steps S11 and S12. Thereafter, the processing unit 6C causes the write-in process to record the return amount and product information of the return electric wire 3 on the IC tag 3A on the distal end side of the return electric wire 3, and when work information is input, This work information is also recorded. The processing unit 6C transmits the return quantity of the return electric wire 3 and product information to the host computer 9 by transmission processing. When the work content is input, the processing unit 6C transmits work information representing the work content to the host computer 9.

  The storage box 7 is for putting the end material of the electric wire 3 generated when the electric wire 3 is laid, and includes a box body 7A, an antenna portion 7B, and a control portion 7C as shown in FIG. . The box main body 7A is a box-shaped container in which mill ends are placed. The antenna portion 7B is provided at the bottom of the box body 7A, and may be composed of a plurality of antennas or a single antenna. The antenna unit 7B transmits an electromagnetic wave to the IC tag 3A as the end material under the control of the control unit 7C. Moreover, the antenna part 7B receives the electromagnetic waves from the IC tag 3A of the end material.

  When the control unit 7C receives the inquiry signal and the write signal from the wire management computer 8, the control unit 7C outputs these signals from the antenna unit 7B as electromagnetic waves. When the antenna unit 7B receives the response signal as an electromagnetic wave, the antenna unit 7B reproduces the response signal from the electromagnetic wave and sends it to the wire management computer 8.

  The electric wire management computer 8 performs processing such as measuring the quantity of the end material based on the response signal from the storage box 7, and as shown in FIG. 9, the interface 8A, the input unit 8B, the processing unit 8C, storage unit 8D, transmission / reception unit 8E, and display unit 8F. The interface 8A exchanges various signals between the control unit 7C and the processing unit 8C of the storage box 7. The input unit 8B is operated manually, whereby various information such as a transmission instruction is input to the input unit 8B. The transmission / reception unit 8E transmits / receives information to / from the host computer 9 via the base station 101 of the communication network 100 under the control of the processing unit 8C. The display unit 8F displays various information such as information input to the input unit 8B under the control of the processing unit 8C. The storage unit 8D stores various processing procedures of the processing unit 8C.

  The processing unit 8C performs various types of processing related to the scraps according to the processing procedure stored in the storage unit 8D. When the processing unit 8C receives an instruction indicating the start of the offcut quantity management processing from the input unit 6B, the processing unit 8C starts the processing illustrated in FIG. The processing unit 8C sends an inquiry signal to the interface 8A (step S31). Thereafter, it is determined whether there is a response signal from the IC tag of the end material (step S32). When there is no response signal in step S32, since the worker has not put the end material in the box body 7A, the processing unit 8C returns the process to step S31. If there is a response signal in step S32, the processing unit 8C receives the response signal via the interface 8A (step S33), and extracts the order information included in the response signal (step S34). Thereafter, the processing unit 8C calculates the length of the end material using the order information (step S35).

The method for calculating the end material in step S35 is as follows. When there is only one piece of piece order information, the processing unit 8C sets the length of the piece to D. When the order information of the mill ends is continuous and the numbers are from “T _k ” to “T _{k + m} ”, the processing unit 8C uses this continuous set of numbers,
(T _{k + m} −T _k ) · D
Is calculated. This calculation result is the length of the end material, that is, the end material quantity. And when there are a plurality of sets of consecutive numbers, the sum of the lengths of the end materials calculated using the consecutive numbers of each set is taken as the end material quantity. Moreover, the number of each set is made into the number of end materials as needed.

  After step S35, the processing unit 8C stores the amount of offcuts as a calculation result in the storage unit 8D (step S36). Further, the processing unit 8C stores the product information included in the response signal received in step S33 in the storage unit 8D (step S37), and ends the milling material quantity management process.

  The processing unit 8C performs the next transmission process after the end material quantity management process is completed. When an instruction for transmission to the host computer 9 is input to the input unit 8B, the processing unit 8C reads the amount of scrap material and product information stored in the storage unit 8D, and controls the communication network 100 by controlling the transmission / reception unit 8E. Then, the quantity of the end material wire and the product information are transmitted to the host computer 9.

  The host computer 9 manages the unused wires 3 wound around the wire drum 2 and always keeps the latest product information such as the manufacturer, year of manufacture, and lot number of the wires 3.

  When the host computer 9 receives the used amount and product information of the drawn wire from the wire management computer 6, the host computer 9 stores the used amount and product information of the drawn wire together with, for example, the management number of the wire drum 2. In addition, the host computer 9 stores the product information of the drawn wire and the position information indicating the position where the drawn wire is laid, and receives the work information from the wire management computer 6, and the work information is also combined. And save. When the host computer 9 receives the product information and the end material quantity of the end material electric wire from the electric wire management computer 8, the host computer 9 stores the end material quantity and the product information of the end material electric wire.

When aged deterioration or product defect at the time of manufacture is found, the host computer 9 instructs repair or replacement of the installed electric wires.

  When the host computer 9 receives the return quantity and product information of the return wire from the wire management computer 6, the host computer 9 compares the product information of the return wire and the latest product information to determine the performance failure of the return wire. . If there is no performance defect in the return wire, the host computer 9 uses the return wire as a reusable wire that can be used in another place. To save the information. Further, when the host computer 9 receives the work information together with the return quantity from the electric wire management computer 6, the host computer 9 also stores the work information. Further, if there is a performance defect in the return electric wire, the host computer 9 determines that the reuse of the return electric wire is impossible, and processes it as electric wire waste.

An operator who lays the electric wire 3 pulls out the electric wire 3 from the electric wire drum 2 supported by the drum mount 1, and places the electric wire 3 on the support base 5 </ b> B ₁ of the read / write device 5. Further, the operator operates the electric wire management computer 6 to input the start of the amount management process for the number of drawn wires 3. Thereafter, after the operator pulls in the pulling direction A, the electric wire 3 is cut at the cutting portion 5E of the read / write device 5. As a result, the end portion of the electric wire 3 wound around the electric wire drum 2 remains in the first antenna portion 5B of the read / write device 5. The electric wire management computer 6 calculates and stores the used quantity that is the length of the drawn electric wire 3 by the drawn quantity management processing of the electric wire 3, and stores the product information of the electric wire 3. Thereafter, the operator operates the electric wire management computer 6 to input a transmission instruction. As a result, the electric wire management computer 6 transmits the stored used quantity and product information of the drawn wires to the host computer 9.
