  By the way, high-precision or high-performance machines are required to have strict control of unauthorized exports, or manufacturers are required to install them under the determined conditions. Relocation management of important machines is important.

  However, the main body of the vibration detection apparatus according to Patent Document 1 detects the movement of a machine in order to detect all vibrations within a predetermined condition range such as erroneous detection of vibrations generated during machining and detection of vibrations caused by earthquakes.

Accordingly, a start state is detected, a power ON command a is issued to the power ON / OFF circuit 15, and atmospheric pressure detection for relocation determination is started. Further, in the invention of claim 7 (corresponding to the first and second embodiments) based on the invention of any one of claims 1 to 5, the relocation determining means 9 is An end state is detected as the state changes, and a power OFF command d is issued to the power ON / OFF circuit 15 and the atmospheric pressure detection for relocation determination is ended. By the way, for example, the state change of the device 1 mainly occurs in the presence or absence of vibration generated in the device 1 related to the relocation, whether or not the power supply to the device 1 mainly related to the relocation is interrupted, or at the time of relocation. The presence or absence of atmospheric pressure fluctuations can be mentioned. In the sixth aspect of the invention, pressure detection for relocation determination is started in accordance with a change in the state of the device 1, and in the seventh aspect of the invention, pressure detection for relocation determination is ended in accordance with a change in the state of the device 1. Therefore, it is possible to save the power source for detecting the atmospheric pressure.

When the power supply to the device 1 is cut off, it is determined that the device 1 is transferred or When the power supply is restored, a power OFF command d is issued to the power ON / OFF circuit 15 and the relocation determination is completed. In the invention of claim 9, for example, when the power cable 16 is disconnected from the device 1 while the power cable 16 is connected to the device 1 and the power supply to the device 1 is cut off, there is a possibility that the preparation for relocation is started. For example, if the power supply cable 16 is connected to the device 1 with the power cable 16 disconnected from the device 1 and the power supply to the device 1 is restored, the transfer may be completed. The relocation determination was finished to occur. In addition, when the determination of the presence or absence of relocation became clear, the relocation determination was stopped at that stage. Therefore, it is possible to save a power source for determining whether or not to relocate.

  In the invention of claim 10 (corresponding to the second embodiment) premised on the invention of any one of claims 1 to 9, the device 1 detects vibration generated in the device 1. A vibration sensor 23 is attached, and the relocation determining means 9 is connected to the power ON / OFF circuit 15 based on the vibration detection signal e obtained from the detection data from the vibration sensor 23 in a state where the power supply to the device 1 is cut off. A power ON command a is issued and atmospheric pressure detection for relocation determination is started. In invention of Claim 10, when conveying the apparatus 1 in order to transfer the apparatus 1, since vibration may arise in the apparatus 1, the atmospheric | air pressure detection for transfer determination was started on condition of the vibration detection.

  In the invention of claim 12 (corresponding to the first and second embodiments), the device 1 includes the device transfer presence / absence detecting device according to any one of claims 1 to 11 and the device main body 2. The relocation presence / absence processing unit 2a is provided, and the relocation determining means 9 of the relocation presence / absence detecting device of this device provides information on the determination of relocation presence / absence in response to a request from the relocation presence / absence processing unit 2a of the device main body 2. 2, the transfer presence / absence processing unit 2 a of the device main body 2 issues a power ON command c to the power ON / OFF circuit 15 when the main body power is supplied to the device main body 2. At the same time, when the information regarding the presence / absence of relocation is received and it is determined that the device 1 is relocated, the operation of the device main body 2 is restricted.

  In the invention of claim 12, since the transfer presence / absence information can be communicated between the transfer discriminating means 9 and the device main body 2 side, if the device 1 is transferred, the device main body 2 can be transferred regardless of whether or not it is improper. Operation can be restricted and unauthorized use of the device 1 can be prevented.

  In the invention of claim 13 (corresponding to the first and second embodiments) premised on the invention of claim 12, the transfer presence / absence processing unit 2a of the device main body 2 performs a release operation when a predetermined release operation is performed. The operation restriction of the main body 2 is released. In the invention of claim 13, the use of the device 1 by a person who can perform a predetermined release operation can be permitted as not being unauthorized use.

  In the present invention, in the device transfer presence / absence detection device, the pressure sensor 12 detects the atmospheric pressure fluctuation around the device 1 according to the height difference H generated when the device 1 is lifted by a crane, for example. The presence / absence determination can be easily performed, and the unauthorized export management function of the device 1 can be enhanced. In addition, it is possible to enhance a function of saving a charging source used in the device relocation presence / absence detection device during relocation. Further, in the device 1 equipped with such a device relocation presence / absence detection device, the operation restriction of the device main body 2 can be restricted and released based on the relocation presence / absence information transferred from the relocation determining means 9 to the device main body 2 side. Thus, unauthorized use of the device 1 can be prevented.

  First, the device transfer presence / absence detecting device according to the first embodiment of the present invention is shown in FIGS. 1, 2, 3, 4, 5, 6 (a) (b) (c) (e), 7, 8, 9, 10 ( Description will be made with reference to a), (b), 11, and 14.

  A machine tool 1 as an apparatus shown in FIG. 2A is installed horizontally with respect to the original installation place 4 at an installation part 3 at the bottom of the machine body 2 as shown in FIGS. ing. A control panel 5 and a power input port 6 are provided on the back side of the machine body 2, and an operation panel 7 is provided on the front side of the machine body 2. A pressure detection unit 8 shown in FIG. 3 is incorporated in the control panel 5. As shown in FIG. 1 (c), the atmospheric pressure detection unit 8 performs a communication process related to the determination of the presence / absence of transfer with the transfer presence / absence processing unit 2a provided in the machine body 2 as shown in FIG.

  In this atmospheric pressure detection unit 8, a flash memory 10 and an I / O 11 as an input / output interface are connected to an MPU 9 (relocation determination means) as a microprocessor unit, and an atmospheric pressure sensor 12 as a pressure sensor is connected to an AD converter. 13, and a power ON / OFF circuit 15 in the power supply circuit 14 is further connected.

  This atmospheric pressure sensor 12 is selected from conventionally known ones, and as shown in FIGS. 2A and 2B, detects an atmospheric pressure that changes in accordance with an altitude difference H generated when the machine tool 1 is lifted by a crane, for example. can do. The atmospheric pressure is inversely proportional to the altitude from the sea level. In the ICAO (International Civil Aviation Organization) standard atmosphere, the atmospheric pressure decreases by 12 pa for every 1 m increase in altitude. For example, when the machine tool 1 is lifted by 1 m over 5 seconds using a crane, the amount of change in atmospheric pressure per second is 2.4 pa / sec. A typhoon or the like can be mentioned as an event in which atmospheric pressure fluctuation is large in nature. FIG. 14 (a) shows the atmospheric pressure fluctuation in a predetermined city during fine weather, and the atmospheric pressure change amount per second is about 0.025 pa / sec. FIG. 14B shows the atmospheric pressure fluctuation at the time of landing of a typhoon in the same predetermined city, and the amount of atmospheric pressure change per second is about 0.51 pa / sec. Therefore, when these pressure change speeds are compared, a sufficiently discriminable difference occurs between the lifting of the machine tool 1 by the crane and a natural phenomenon. In general, when the atmospheric pressure change rate, which is the amount of atmospheric pressure change per unit time, is larger than the atmospheric pressure change rate that fluctuates in nature, it can be detected as relocation.

  In the power supply circuit 14, when the main power is input to the machine tool 1 with the power cable 16 connected to the power input port 6, the main power (DC power) is supplied to the main power terminal portion 17. Is done. The main power terminal 17 is connected to the power switching circuit 18, and the secondary battery 20 charged via the battery charging circuit 19 by the main power terminal 17 is connected to the power switching circuit 18. . The power ON / OFF circuit 15 is supplied with a main power from the main power terminal 17 or a charging source from the secondary battery 20 via the power switching circuit 18. The power supply switching circuit 18 supplies main power to the power ON / OFF circuit 15 when main power is supplied to the main power terminal portion 17, and supplies power when the main power is not supplied to the main power terminal portion 17. A power source from the secondary battery 20 is supplied to the power ON / OFF circuit 15. A relay coil 21 is connected to the main power supply terminal portion 17, and the normally closed contact 22 connected to the power supply ON / OFF circuit 15 is opened and closed by excitation or demagnetization of the relay coil 21. The MPU 9 functions according to the flowcharts shown in FIGS. 4, 5, 7, 8, 9, 11 based on the input signal from the atmospheric pressure sensor 12, and stores various data in the flash memory 10.

  As shown in FIGS. 1A and 1B, in the machine tool 1 installed at the initial installation location 4, the power cable 16 is disconnected from the power input port 6, or the power cable 16 is connected to the power input port 6. If a power failure or a breaker is interrupted due to an earthquake or the like, the machine tool 1 is lifted by, for example, a crane and separated from the original installation location 4 as shown in FIGS. In this case, the supply of the main power supply to the machine tool 1 is cut off, and the supply of the main power supply (DC power supply) is cut off. At the time of the interruption, the normally closed contact 22 is closed by demagnetization of the relay coil 21, and an ON command a is sent to the power ON / OFF circuit 15, and the charging source from the secondary battery 20 is the power switching circuit 18 and the power ON / OFF circuit. 15 is supplied to the MPU 9.

  In the atmospheric pressure detection unit processing shown in FIG. 4, when the machine tool 1 is lifted by, for example, a crane and separated from the original installation place 4 for the purpose of relocation as shown in FIGS. When the supply of the main body power to is interrupted, the MPU 9 is turned on by the charging source from the secondary battery 20 and then based on the main power confirmation signal b input from the main power terminal portion 17 via the I / O 11. When the main body source is confirmed in step S1 and it is determined that the main body power supply is OFF, in step S2, the MPU 9 determines whether or not there is a transfer from the past status signal, and if it is determined that there is no transfer, the process proceeds to step S3. The process ends when it is determined that there has been a relocation. In step S3, the MPU 9 detects the first pattern detection process shown in FIG. 7 or the second pattern detection process shown in FIG. 8 or the third pattern shown in FIG. 9 in order to detect the atmospheric pressure around the machine tool 1. Perform detection processing.

  Further, when the machine tool 1 is relocated to the final installation location and installed, for example, when the main body power is supplied to the machine tool 1 with the power cable 16 reconnected to the power input port 6, FIG. The MPU 9 is turned on by the main power supply based on the power supply ON command c by the main body power supply ON processing shown in FIG. 1 and then the main power supply confirmation signal b input from the main power supply terminal portion 17 through the I / O 11 is used in step S1. When the power supply is checked and it is determined that the main body power supply is ON, the communication processing shown in FIG. 5 is started in step S4 in order to transfer data from the atmospheric pressure detection unit 8 to the machine main body 2 side.

As shown in FIGS. 2A and 2B, when the machine tool 1 is lifted by a crane, for example, the atmospheric pressure around the machine tool 1 fluctuates. Therefore, in the detection process of the first pattern shown in FIG. 12 is used to detect the atmospheric pressure around the machine tool 1. In step S5, the MPU 9 initializes the N data buffers X _i and the non-detection counter i (0 to N−1) shown in FIG. In step S6, if the MPU 9 determines that the main unit power is OFF, it moves to step S7 assuming that the power cable 16 is disconnected from the power input port 6 for relocation, and determines that the main unit power is ON. In such a case, it is assumed that the power cable 16 remains connected to the power input port 6 and the detection process is terminated. In step S7, MPU 9 proceeds to step S8 to store the air pressure data detected by the pressure sensor 12 to the data buffer X _i. In step S8, the MPU 9 distinguishes the atmospheric pressure change calculation function F (X) representing the atmospheric pressure change rate, which is the atmospheric pressure change amount per unit time, from the predetermined threshold value shown in FIG. It is determined whether or not the pressure is within a range equal to or greater than a predetermined threshold value. When it is determined that the pressure is within the predetermined threshold value, the process proceeds to step S9. When it is determined that the pressure is not within the predetermined threshold value, step S10 is performed. Move on. This atmospheric pressure change calculation function F (X) is as illustrated in FIG. In step S9, the MPU 9 sets a status signal indicating that the machine tool 1 is lifted by a crane unlike a natural phenomenon because the pressure change speed is in a range equal to or greater than a predetermined threshold, and ends the detection process. In step S10, the MPU 9 counts non-detection of the atmospheric pressure change speed equal to or greater than a predetermined threshold value, and proceeds to step S11. In step S11, the MPU 9 determines whether or not the non-detection counter i has reached the buffer number N. If it is determined that the counter has not reached, the process proceeds to step S12. In step S12, the MPU 9 resets the non-detection counter i and proceeds to step S13. If the MPU 9 determines in step S11 that the non-detection counter i has not reached the buffer number N, the process also proceeds to step S13. In step S13, the MPU 9 waits for a predetermined time Δt seconds (for example, 1 second), and returns to step S6 to repeat the detection process until the main body power supply is turned on or a status signal indicating relocation is set.

Further, when the machine tool 1 is lifted by a crane, for example, as shown in FIGS. 2 (a) and 2 (b), the atmospheric pressure around the machine tool 1 fluctuates. Therefore, in the second pattern detection process shown in FIG. in S14, MPU 9 initializes the N data buffers X _i and inactive counter i and (0 to N-1) and moved counter s (0 to m) shown in Figure 6 (b). In step S15, if the MPU 9 determines that the main unit power is OFF, the MPU 9 moves to step S16 assuming that the power cable 16 has been disconnected from the power input port 6 for relocation, and determines that the main unit power is ON. In such a case, it is assumed that the power cable 16 remains connected to the power input port 6 and the detection process is terminated. In step S16, the MPU 9 stores the atmospheric pressure data detected by the atmospheric pressure sensor 12 in the data buffer X _i and proceeds to step S17. In step S17, the MPU 9 distinguishes the atmospheric pressure change calculation function F (X) representing the atmospheric pressure change rate, which is the atmospheric pressure change amount per unit time, from the predetermined threshold (natural pressure fluctuation shown in FIG. 10B). It is determined whether or not the pressure is within a range equal to or higher than a predetermined threshold value. If it is determined that the pressure is within the predetermined threshold, the process proceeds to step S18. If it is determined that the pressure is not within the predetermined threshold, the process proceeds to step S19. Move on. This atmospheric pressure change calculation function F (X) is as illustrated in FIG. In step S18, the MPU 9 counts the relocation counter s, and proceeds to step S20. In step S20, the MPU 9 determines whether or not the relocation counter s has reached a specified number or more. If it is determined that the transfer counter s has not reached, the process proceeds to step S21. If it is determined that the transfer counter s has not reached, the process proceeds to step S22. In step S19, the MPU 9 resets the relocation counter s and proceeds to step S22. In step S21, the MPU 9 lifts the machine tool 1 by a crane unlike a natural phenomenon because the atmospheric pressure change rate has continuously changed over a predetermined specified time T within a range equal to or higher than a predetermined threshold as shown in FIG. 10B. The state signal with relocation is set and the detection process is terminated. In step S22, the MPU 9 counts the non-detection of the atmospheric pressure change speed equal to or higher than the predetermined threshold continuously changing for the specified time T or more, and proceeds to step S23. In step S23, the MPU 9 determines whether or not the non-detection counter i has reached the buffer number N. If it is determined that it has, the process proceeds to step S24. In step S24, the MPU 9 resets the non-detection counter i and proceeds to step S25. If the MPU 9 determines in step S23 that the non-detection counter i has not reached the buffer number N, the process also proceeds to step S25. In step S25, the MPU 9 waits for a predetermined time Δt seconds (for example, 1 second), and returns to step S15 to repeat the detection process until the main body power is turned on or a status signal indicating relocation is set.

Also, as shown in FIGS. 2A and 2B, when the machine tool 1 is lifted by, for example, a crane, the atmospheric pressure around the machine tool 1 fluctuates. Therefore, in the third pattern detection process shown in FIG. in S26, MPU 9 initializes the N data buffers X _i and inactive counter i and (0 to N-1) and moved counter s (0 to m) shown in FIG. 6 (c). In step S27, if the MPU 9 determines that the main unit power is OFF, it moves to step S28 assuming that the power cable 16 has been disconnected from the power input port 6 for relocation, and determines that the main unit power is ON. In such a case, it is assumed that the power cable 16 remains connected to the power input port 6 and the detection process is terminated. In Step S28, MPU 9 proceeds to step S29 to store the air pressure data detected by the pressure sensor 12 to the data buffer X _i. In step S29, the MPU 9 distinguishes the atmospheric pressure change calculation function F (X) representing the atmospheric pressure change rate, which is the atmospheric pressure change amount per unit time, from the predetermined lower limit threshold (natural pressure fluctuation shown in FIG. 10C). It is determined whether or not the pressure is within a range equal to or higher than the atmospheric pressure change rate. If it is determined that the pressure is within the predetermined lower limit threshold, the process proceeds to step S30. In step S30, the MPU 9 distinguishes the atmospheric pressure change calculation function F (X) representing the atmospheric pressure change rate, which is the atmospheric pressure change amount per unit time, from the predetermined upper limit threshold (natural pressure fluctuation shown in FIG. 10C). It is determined whether or not the pressure is within a range equal to or less than a predetermined upper limit threshold, and the process proceeds to step S31. In step S31, the MPU 9 counts the relocation counter s and proceeds to step S32. In step S32, the MPU 9 determines whether or not the relocation counter s has reached a predetermined number or more. If it is determined that the transfer counter s has not reached, the process proceeds to step S33. In step S33, the MPU 9 changes the atmospheric pressure change speed continuously over a predetermined specified time T within a range not less than a predetermined lower limit threshold and not more than a predetermined upper limit threshold as shown in FIG. A state signal indicating that the machine 1 is lifted is set and the detection process is terminated. When the MPU 9 determines in step S29 that the atmospheric pressure change speed is not in the range equal to or greater than the predetermined lower limit threshold value, the process proceeds to step S35. If the MPU 9 determines in step S30 that the atmospheric pressure change speed is not in the range of the predetermined upper limit threshold value or less, the process proceeds to step S35. In step S35, the MPU 9 resets the relocation counter s and proceeds to step S34. In step S34, the MPU 9 counts the non-detection of the atmospheric pressure change speed in the range not less than the predetermined lower limit threshold and not more than the predetermined upper limit threshold continuously changing for the predetermined specified time T or more, and proceeds to step S36. In step S36, the MPU 9 determines whether or not the non-detection counter i has reached the buffer number N. If it is determined that it has, the process proceeds to step S37. In step S37, the MPU 9 resets the non-detection counter i and proceeds to step S38. If the MPU 9 determines in step S36 that the non-detection counter i has not reached the buffer number N, the process also proceeds to step S38. In step S38, the MPU 9 waits for a predetermined time Δt seconds (for example, 1 second), and returns to step S27 to repeat the detection process until the main body power supply is turned on or a status signal indicating relocation is set.

  As described above, the communication process shown in FIG. 5 is performed when the machine tool 1 is moved to the final installation location and installed, for example, with the power cable 16 reconnected to the power input port 6. This is performed when the main unit power is supplied. When the main body power is supplied to the machine tool 1, the power ON / OFF circuit 15 is turned on by the power ON command c from the relocation presence / absence processing unit 2 a side of the machine main body 2, and the main power is supplied to the MPU 9 via the power switching circuit 18. Is supplied. In step S40, when a status signal indicating whether or not relocation has been sent from the MPU 9 to the relocation presence / absence processing unit 2a of the machine body 2, in step S41, the MPU 9 determines whether or not relocation has occurred. Move. When the MPU 9 determines in step S42 that there has been a transfer resetting state reset command from the transfer presence / absence processing unit 2a of the machine body 2, the process proceeds to step S43. In step S43, the MPU 9 resets the status signal with relocation, and proceeds to step S44. In step S42, the MPU 9 repeats the determination when it is determined that the transfer presence / absence processing unit 2a of the machine main body 2 has not received a transfer presence / absence state reset command. In step S41, the MPU 9 also moves to step S44 when determining that there has been no relocation. In step S44, the power ON / OFF circuit 15 is turned OFF by the power OFF command d from the MPU 9, the main power supply to the MPU 9 is cut off, and the communication process is completed. That is, in steps S40 to S44, after a status signal with transfer is transmitted to the transfer presence / absence processing unit 2a of the machine main body 2, the MPU 9 is moved by a command from the transfer presence / absence processing unit 2a of the machine main body 2 when the transfer is performed. The presence / absence status signal is reset to end the communication process, and the MPU 9 also ends the communication process when there is no relocation.

  Finally, a main body power ON process shown in FIG. 11 is performed so that the machine main body 2 can be used. When the main body power is supplied to the machine tool 1, in step S45, the power ON command c is output from the transfer presence / absence processing unit 2a side of the machine main body 2 to the atmospheric pressure detection unit 8 side, and the process proceeds to step S46. On the atmospheric pressure detection unit 8 side, the power ON / OFF circuit 15 is turned ON by this power ON command c, and the main power is supplied to the MPU 9 via the power switching circuit 18. In step S46, the above-described communication process is performed between the atmospheric pressure detection unit 8 and the transfer presence / absence processing unit 2a of the machine body 2, and the process proceeds to step S47. In step S47, the transfer presence / absence processing unit 2a of the machine body 2 determines the presence / absence of transfer, and if it is determined that transfer has occurred, the process proceeds to step S48. In step S48, the transfer presence / absence processing unit 2a of the machine body 2 notifies the transfer by an alarm or a display screen provided on the operation panel 7, performs operation restriction, and moves to step S49. For example, the operation restriction can include prohibiting activation by automatic operation. In step S49, a release operation for canceling the operation restriction is performed, and the process proceeds to step S50. For example, the canceling operation can be performed by operating with a keyed switch or inputting a password when the canceling switch is operated. In step S50, the transfer presence / absence processing unit 2a of the machine main body 2 determines whether or not the release operation is performed according to the correct procedure, and when it is determined that the release operation is performed according to the correct procedure, the process proceeds to step S51. For example, the correct procedure may include performing the release operation described above. In step S50, the transfer presence / absence processing unit 2a of the machine body 2 returns to step S49 and repeats this determination when determining that the release operation has not been performed in the correct procedure. In step S51, the above-described communication processing is performed between the atmospheric pressure detection unit 8 and the transfer presence / absence processing unit 2a of the machine main body 2, and in step S42 of FIG. The relocation presence / absence processing unit 2a of the machine body 2 transmits a relocation presence / absence state reset command to the atmospheric pressure detection unit 8 waiting for a reset command, and the process proceeds to step S52. In step S52, the transfer presence / absence processing unit 2a of the machine main body 2 releases the alarm and display screen provided on the operation panel 7 and the operation restriction, and the main body power ON process ends. In step S47, the transfer presence / absence processing unit 2a of the machine main body 2 also ends the main body power ON process when it is determined that there is no transfer.

  Next, the device relocation presence / absence detection apparatus according to the second embodiment of the present invention is mainly illustrated in FIGS. 1, 2, 12, 4, 5, 6 (d) (e), 13, mainly on the differences from the first embodiment. 10 (c), 11 and 14 will be described. Incidentally, FIGS. 1, 2, 4, 5, 11, and 14 use the same drawings as in the first embodiment, FIG. 12 shows FIG. 3 of the first embodiment, and FIGS. 6 (d) and 6 (e) show the first. 6 (a), (b), (c), and (e) of the embodiment, FIG. 13 is FIGS. 7, 8, and 9 of the first embodiment, and FIG. 10 (c) is FIG. 10 (a) of the first embodiment. ) And (b) respectively.

  In the atmospheric pressure detection unit 8 shown in FIG. 12, a vibration sensor 23 is connected in series to a normally closed contact 22 connected to a power ON / OFF circuit 15. The vibration sensor 23 is selected from conventionally known ones, and switches from OFF to ON when a vibration exceeding a specified value is detected. While the main power supply to the machine tool 1 is cut off, the main power supply (DC power supply) is cut off, and the normally closed contact 22 is closed due to the demagnetization of the relay coil 21, causing a vibration exceeding the specified value. When the vibration sensor 23 is turned ON, a power ON command a is sent to the power ON / OFF circuit 15 based on the vibration detection signal e obtained from the detection data from the vibration sensor 23, and charging from the secondary battery 20 is performed. The source is supplied to the MPU 9 through the power supply switching circuit 18 and the power supply ON / OFF circuit 15. The MPU 9 functions according to the flowcharts shown in FIGS. 4, 5, 11, and 13 based on the input signal from the atmospheric pressure sensor 12 and the like, and stores various data in the flash memory 10.

  The barometric pressure detection unit process shown in FIG. 4, the communication process shown in FIG. 5, and the main body power ON process shown in FIG. 11 are the same as those in the first embodiment, but the second embodiment is compared with the first embodiment. The detection process shown in FIG. 13 is changed. The detection process of the second embodiment shown in FIG. 13 corresponds to the third pattern of the detection process shown in FIG. 9 in the first embodiment, but the detection process or diagram of the first pattern shown in FIG. 7 in the first embodiment. The second pattern detection process shown in FIG.

In Step S53, MPU 9 is FIG 6 N pieces of data buffers shown in (d) X _i and the non-detection counter i (0~N-1) and moved counter s (0 to m) and the vibration non-detection counter k and pressure The non-detection counter u is initialized and the detection start time is set. In step S54, if the MPU 9 determines that the main body power is OFF, the MPU 9 moves to step S55 assuming that the power cable 16 has been disconnected from the power input port 6 for relocation, and determines that the main power is ON. In such a case, it is assumed that the power cable 16 remains connected to the power input port 6 and the detection process is terminated. In Step S55, MPU 9 proceeds to step S56 to store the air pressure data detected by the pressure sensor 12 to the data buffer X _i. In step S56, the MPU 9 detects the vibration signal generated when the vibration sensor 23 is turned on via the I / O 11 to confirm the presence or absence of vibration, and moves to step S57 when determining that there is vibration. If it is determined that there is no vibration, the process proceeds to step S58. In step S57, the MPU 9 resets the vibration non-detection counter k because there is vibration, and proceeds to step S59. In step S58, the MPU 9 counts the vibration non-detection counter k, and proceeds to step S59. In step S59, the MPU 9 distinguishes the atmospheric pressure change calculation function F (X) representing the atmospheric pressure change rate, which is the atmospheric pressure change amount per unit time, from the predetermined lower limit threshold (natural pressure fluctuation shown in FIG. 10C). It is determined whether or not the pressure is within a range equal to or higher than the atmospheric pressure change rate. If it is determined that the pressure is within the predetermined lower limit threshold, the process proceeds to step S60. In step S60, the MPU 9 distinguishes the atmospheric pressure change calculation function F (X) representing the atmospheric pressure change rate, which is the atmospheric pressure change amount per unit time, from the predetermined upper limit threshold (natural pressure fluctuation shown in FIG. 10C). It is determined whether or not the pressure is within a range equal to or less than a predetermined upper limit threshold, and the process proceeds to step S61. In step S61, the MPU 9 counts the transfer counter s and resets the atmospheric pressure non-detection counter u, and proceeds to step S62. If the MPU 9 determines in step S59 that the atmospheric pressure change speed is not in the range equal to or greater than the predetermined lower limit threshold value, the process proceeds to step S63. If the MPU 9 determines in step S60 that the atmospheric pressure change speed is not in the range equal to or less than the predetermined upper limit threshold value, the process also proceeds to step S63. In step S63, the MPU 9 resets the transfer counter s and counts the atmospheric pressure non-detection counter u, and proceeds to step S62. In step S62, the MPU 9 determines whether or not the relocation counter s has reached a predetermined prescribed number or more. If it is determined that the transfer counter s has not reached, the process proceeds to step S64. If it is determined that it has not, the process proceeds to step S65. In step S64, the MPU 9 changes the pressure change rate continuously over a predetermined specified time T in the range of the predetermined lower limit threshold and lower than the predetermined upper limit threshold as shown in FIG. A state signal indicating that the machine 1 is lifted is set, and the process proceeds to step S66. In step S66, the MPU 9 sets a detection end time and outputs a power OFF, and ends the detection process. In step S65, the MPU 9 determines whether or not both the atmospheric pressure non-detection counter u and the vibration non-detection counter k are equal to or greater than a predetermined specified value. If it is determined that they are not, the process proceeds to step S66. If so, the process proceeds to step S67. In step S67, the MPU 9 counts the non-detection of the atmospheric pressure change speed in the range not less than the predetermined lower limit threshold and not more than the predetermined upper limit threshold continuously changing for the predetermined specified time T or more, and proceeds to step S68. In step S68, the MPU 9 determines whether or not the non-detection counter i has reached the buffer number N. If it is determined that it has, the process proceeds to step S69. In step S69, the MPU 9 resets the non-detection counter i and proceeds to step S70. If the MPU 9 determines in step S68 that the non-detection counter i has not reached the buffer number N, the process also proceeds to step S70. In step S70, the MPU 9 waits for a predetermined time Δt seconds (for example, 1 second), and returns to step S54 to repeat the detection process until the main body power is turned on or a status signal indicating relocation is set. That is, since the atmospheric pressure non-detection counter u and the vibration non-detection counter k can be converted into time, the detection of the atmospheric pressure data of the machine tool 1 by the atmospheric pressure sensor 12 is counted from the detection start time, and the detection of the atmospheric pressure data is a predetermined specified value. If the vibration sensor 23 does not continue to exceed the predetermined specified time and the vibration sensor 23 detects the vibration of the machine tool 1 from the detection start time, the detection of the vibration is a predetermined specified value as the predetermined specified value. If it is not performed continuously beyond the time, in step S66, the detection end time is set and the power is turned off, and the detection process ends. In step S65, the MPU 9 detects the vibration of the machine tool 1 by the vibration sensor 23 and the atmospheric pressure data of the machine tool 1 by the atmospheric pressure sensor 12 within the predetermined specified time as the predetermined specified value. If it is determined that at least one of the counter k and the pressure non-detection counter u does not exceed the predetermined specified value, the process returns to step 54 and the detection process is repeated. Therefore, in steps S53 to S66, even if the atmospheric pressure data is detected for each detection process or the vibration of the machine tool 1 is detected, the detection of the atmospheric pressure data of the machine tool 1 or the vibration of the machine tool 1 is detected. As long as the detection is performed within the predetermined specified time, the detection process is repeated any number of times. However, when the detection process exceeds the predetermined specified time, the detection process ends.

This embodiment has the following effects.
* In the first and second embodiments, if the machine tool 1 is lifted by a crane, for example, when moved, there is a difference in altitude between the machine tool 1 installed at the original installation location 4 and the machine tool 1 lifted. Since H is generated, the atmospheric pressure around the machine tool 1 changes. Focusing on this point, the atmospheric pressure variation is detected by the atmospheric pressure sensor 12, and the presence / absence of relocation is determined using the atmospheric pressure data obtained from the detected data. Therefore, it is easier to determine the presence or absence of relocation by preventing erroneous detection of relocation and avoiding adverse effects of vibrations generated during machining or vibration caused by earthquakes, compared to the case of relocation determination based solely on vibration detection. be able to.

  * In the first embodiment (see FIG. 7), attention is paid to the fact that the pressure change speed generated when the machine tool 1 is moved up by a crane, for example, is larger than the pressure change speed fluctuating in nature. A predetermined threshold value was set to distinguish it from natural atmospheric pressure fluctuations, and it was determined that the machine tool 1 was moved when the pressure change speed was in a range equal to or higher than the predetermined threshold value. Accordingly, it is possible to easily determine the presence or absence of relocation by distinguishing it from the atmospheric pressure fluctuation within the range below the predetermined threshold.

  * In the first embodiment (see FIG. 8), it can be confirmed that the pressure changes continuously and continuously changes for a predetermined specified time or more in a range equal to or higher than a predetermined threshold. Therefore, for example, a range above a predetermined threshold after suddenly rising to a range above a predetermined threshold due to atmospheric pressure fluctuations in the control panel 5 that may occur when opening and closing the lid of the control panel 5 incorporating the atmospheric pressure detection unit 8 Thus, it is possible to easily determine whether or not to relocate by distinguishing it from an unstable pressure change speed that returns to the range below the predetermined threshold without continuously changing for a predetermined specified time or more.

  * In the first embodiment (see FIG. 9) and the second embodiment (see FIG. 13), the pressure change speed that occurs when the machine tool 1 is lifted by a crane, for example, when moved, varies in nature. Focusing on the larger value, a predetermined lower limit threshold was set in order to distinguish it from natural pressure fluctuations. Therefore, when the atmospheric pressure change speed is in a range equal to or greater than the predetermined lower limit threshold, it is possible to easily determine whether or not to relocate by distinguishing it from natural atmospheric pressure fluctuation in a range less than the predetermined lower threshold. In addition, since the predetermined upper limit threshold is set in addition to the predetermined lower limit threshold, for example, the atmospheric pressure change speed due to the atmospheric pressure fluctuation in the control panel 5 that may occur when the lid of the control panel 5 incorporating the atmospheric pressure detection unit 8 is opened and closed. Regardless of whether or not is in the range not less than the lower limit threshold and not more than the upper limit threshold, it is possible to easily determine whether or not to move by eliminating the pressure change rate that suddenly rose above the predetermined upper limit threshold.

  * In the first embodiment (see FIG. 9) and the second embodiment (see FIG. 13), the air pressure continuously changes over a predetermined specified time within a range not less than a predetermined lower limit threshold and not more than a predetermined upper limit threshold at a stable pressure change rate. It can be done by confirming that there is. Therefore, for example, due to atmospheric pressure fluctuations in the control panel 5 that may occur when the lid of the control panel 5 incorporating the atmospheric pressure detection unit 8 is opened and closed, it suddenly exceeds a range that is greater than or equal to the predetermined lower limit threshold and less than or equal to the predetermined upper limit threshold. It is easy to determine the presence or absence of relocation by distinguishing from an unstable pressure change rate that returns to the range below the predetermined lower limit threshold without rising continuously for a predetermined specified time or more in the range above the predetermined lower limit threshold after rising. can do.

  * If the power supply to the machine tool 1 is cut off, the move preparation may be underway. Therefore, the relocation determination is started. When the power supply to the machine tool 1 is restored, the transfer is completed. Because the possibility arises, the relocation determination is terminated, and when the determination of the presence / absence of relocation becomes clear, the relocation determination is stopped at that stage, and the power source for determining the relocation can be saved.

  * It is possible to save the power supply for atmospheric pressure detection by starting the atmospheric pressure detection for relocation determination on the condition that the vibration detection by the vibration sensor 23 is performed. In addition, when the vibration detection and the atmospheric pressure detection of the machine tool 1 are not continuously performed beyond the specified time after the start of the atmospheric pressure detection for the relocation determination, the atmospheric pressure detection for the relocation determination is ended and the atmospheric pressure detection is performed. Can save power.

  * If there is a relocation of the machine tool 1, the operation of the machine tool 2 is restricted to prevent unauthorized use of the machine tool 1, and the operation restriction of the machine tool 1 can be lifted if a predetermined release operation is performed. it can.

For example, the following embodiment may be configured as follows.
In the first and second embodiments, it is determined that the equipment is moved when the atmospheric pressure change rate continuously changes for a specified time or more within the range of the lower limit threshold or more and the upper limit threshold or less. If the pressure change rate is within the range of the upper limit threshold and lower than the upper limit threshold, it is determined that the equipment has been moved even if the atmospheric pressure change rate does not continuously change over the specified time within the range of the lower limit threshold and lower. You may make it do.
