In particular, in order to prohibit use for military or terrorist purposes, application and permission from the Ministry of Economy, Trade and Industry is required in order to relocate machine tools in the aforementioned foreign countries.
　そのため工作機械を製造する各社では、海外輸出機に移設検知システムを搭載することで、不適正な移設または転売を抑制する取り組みを行っている。 Therefore, companies that manufacture machine tools are making efforts to suppress improper relocation or resale by installing a relocation detection system in overseas export machines.
　その一例として、特許文献１または特許文献２のように、ＧＰＳ機能を利用して移設を検知する移設検知システムがある。 As an example, there is a relocation detection system that detects relocation using the GPS function, as in Patent Document 1 or Patent Document 2.
　図７に示すように、従来の移設検知システムは主に、ＧＰＳアンテナ１、情報処理システム７及び機械起動ロック解除手段８を備え、工作機械１０に接続される。また、情報処理システム７は、現在位置取得手段２、現在位置比較手段３、設置位置記憶手段４、機械起動ロック手段５及び現在位置変更手段６を備える。 As shown in FIG. 7, the conventional relocation detection system mainly includes a GPS antenna 1, an information processing system 7, and a machine activation lock release means 8, and is connected to a machine tool 10. The information processing system 7 includes a current position acquisition unit 2, a current position comparison unit 3, an installation position storage unit 4, a machine activation lock unit 5, and a current position change unit 6.
　上述のＧＰＳアンテナ１は、ＧＰＳ衛星からの電波の受信を行う。 The GPS antenna 1 described above receives radio waves from GPS satellites.
　上述の現在位置取得手段２は、ＧＰＳアンテナ１で受信した現在位置情報を取得し、現在位置比較手段３と、現在位置変更手段６に出力する。 The current position acquisition unit 2 described above acquires the current position information received by the GPS antenna 1 and outputs the current position information to the current position comparison unit 3 and the current position change unit 6.
　上述の設置位置記憶手段４は、工作機械１０が設置されることを許可する設置許可場所情報が予め記憶され、現在位置比較手段３へ出力する。 The installation position storage means 4 described above stores in advance installation permission place information that permits the machine tool 10 to be installed, and outputs it to the current position comparison means 3.
　上述の現在位置比較手段３は、現在位置取得手段２から入力した情報と、設置位置記憶手段４から入力した情報とを比較し、現在位置情報と設置許可場所情報が一致しているか否かを判断し、判断結果を機械起動ロック手段５へ出力する。 The above-mentioned current position comparison means 3 compares the information input from the current position acquisition means 2 with the information input from the installation position storage means 4, and determines whether the current position information and the installation permission place information match. The determination result is output to the machine activation lock means 5.
　上述の機械起動ロック手段５は、現在位置比較手段３において、現在位置と設置許可場所が一致していないと判断されると、工作機械１０が移設されたものとし、後述する通り、工作機械１０の起動制限を行い、ＮＣ装置９のパスワード入力機能のみを起動可能とし、規定値未満の入力回数で正確なパスワードが入力されれば起動制限を解除し、規定値未満の入力回数で正確なパスワードが入力されなければ、工作機械１０の起動停止を行う。 When the current position comparing means 3 determines that the current position does not coincide with the installation permitted place, the machine activation lock means 5 described above is assumed to have moved the machine tool 10, and as will be described later, the machine tool 10 The activation restriction can be activated, and only the password input function of the NC device 9 can be activated. If an accurate password is entered with the number of inputs less than the specified value, the activation restriction is canceled, and the accurate password is entered with the number of inputs less than the specified value. If is not input, the machine tool 10 is started and stopped.
　上述の機械起動ロック解除手段８は、機械起動ロック手段５による工作機械１０の起動停止を解除し、工作機械１０を起動させる。その方法は２通りで、１つはＮＣ装置９に直接出力して起動させる方法、２つには現在位置変更手段６に出力して設置許可場所を変更する方法である。 The above-described machine start lock release means 8 releases the start / stop of the machine tool 10 by the machine start lock means 5 and starts the machine tool 10. There are two methods, one is a method in which the NC device 9 is directly output and activated, and the other is a method in which the current position changing means 6 is output to change the installation permission place.
　上述の現在位置変更手段６は、機械起動ロック解除手段８から工作機械１０の起動停止解除の情報を入力すると、設置位置記憶手段４の設置許可場所情報を、現在位置取得手段２から入力した現在位置情報と一致させるものである。これにより、機械起動ロック手段５において工作機械１０が移設されていないものとすることで、機械起動ロック手段５によるＮＣ装置９の起動停止を解除し、工作機械１０を起動させることができる。 When the above-described current position changing means 6 receives the information on the start / stop release of the machine tool 10 from the machine activation lock releasing means 8, the current permitted position information of the installation position storage means 4 is input from the current position acquisition means 2. It matches the position information. As a result, it is assumed that the machine tool 10 is not moved in the machine activation lock unit 5, so that the activation stop of the NC device 9 by the machine activation lock unit 5 can be released and the machine tool 10 can be activated.
　以下、従来の移設検知システムの動作を、図８のフローチャートを用いて説明する。 Hereinafter, the operation of the conventional relocation detection system will be described with reference to the flowchart of FIG.
　ステップＳ１では、現在位置取得手段２により、ＧＰＳアンテナ１で受信した現在位置情報を取得する。 In step S1, the current position information received by the GPS antenna 1 is acquired by the current position acquisition means 2.
　ステップＳ２では、現在位置比較手段３により、現在位置取得手段２から入力した現在位置情報と、設置位置記憶手段４から入力した設置許可場所情報とを比較し、工作機械１０の位置が許容エリア内か否か、つまり工作機械１０が移設されていないか否かを判断する。許容エリア内であればステップＳ８へ、そうでなければステップＳ３へ移行する。 In step S2, the current position comparison means 3 compares the current position information input from the current position acquisition means 2 with the permitted installation location information input from the installation position storage means 4, and the position of the machine tool 10 is within the allowable area. Whether or not the machine tool 10 has not been moved. If it is within the allowable area, the process proceeds to step S8, and if not, the process proceeds to step S3.
　ステップＳ３では、現在位置比較手段３から許容エリア外であるとの情報が機械起動ロック手段５に入力されると、機械起動ロック手段５は工作機械１０が移設されたものとし、工作機械１０内のＮＣ装置９に起動制限をかけ、パスワード入力機能のみが作動するようにする。 In step S3, when information indicating that the current position is outside the allowable area is input to the machine activation lock unit 5 from the current position comparison unit 3, the machine activation lock unit 5 assumes that the machine tool 10 has been moved. The activation restriction is applied to the NC device 9 so that only the password input function is activated.
　ステップＳ４では、ＮＣ装置９でのパスワード入力において、入力回数が規定値以上か否かを判断する。規定値以上であればステップＳ５へ、規定値未満であればステップＳ６へ移行する。 In step S4, it is determined whether or not the number of times of input in the NC device 9 is greater than a specified value. If it is equal to or greater than the specified value, the process proceeds to step S5, and if it is less than the specified value, the process proceeds to step S6.
　ステップＳ５では、機械起動ロック手段５によって、工作機械１０が移設されたものとして工作機械１０の起動停止を行う。（但し、上述のように、機械起動ロック解除手段８により起動することが可能である。） In step S5, the machine activation lock means 5 starts and stops the machine tool 10 assuming that the machine tool 10 has been moved. (However, as described above, it can be activated by the machine activation lock releasing means 8.)
　ステップＳ６及びステップＳ７には、ＮＣ装置９におけるパスワードの入力回数が規定値未満のときに移行され、ステップＳ７ではパスワードが正確に入力されているか否かを判断する。パスワードが正確に入力されていればステップＳ８へ、そうでなければステップＳ４へ移行する。 The process proceeds to step S6 and step S7 when the number of times the password is input in the NC device 9 is less than the specified value, and in step S7, it is determined whether or not the password is correctly input. If the password is correctly input, the process proceeds to step S8, and if not, the process proceeds to step S4.
　ステップＳ８では、機械起動ロック手段５による工作機械１０の起動制限または起動停止を解除し、工作機械１０の起動を行う。 In step S8, the start restriction or the start / stop of the machine tool 10 by the machine start lock means 5 is released, and the machine tool 10 is started.
　従来の移設検知システムでは、主に上述のようにして工作機械の移設検知を行う。 The conventional relocation detection system mainly detects relocation of machine tools as described above.

　上述の情報処理システム２１は、通信システム１４から入力した情報を基に工作機械１０の起動制限または起動停止を行い、基地局情報入力手段１５、基地局情報比較手段１６、基地局情報記憶手段１７、基地局情報変更手段１８、電波状態確認手段１９、通信状態確認手段２０及び機械起動ロック手段３５を備える。 The information processing system 21 described above performs start restriction or start stop of the machine tool 10 based on information input from the communication system 14, and base station information input means 15, base station information comparison means 16, base station information storage means 17. , A base station information changing unit 18, a radio wave state confirming unit 19, a communication state confirming unit 20, and a machine activation lock unit 35.
　上述の基地局情報入力手段１５は、基地局情報取得手段１３で取得した情報を基地局情報比較手段１６と基地局情報変更手段１８へ出力する。 The base station information input means 15 described above outputs the information acquired by the base station information acquisition means 13 to the base station information comparison means 16 and the base station information change means 18.
　上述の基地局情報記憶手段１７は、通信アンテナ１１が通信に使用することを許可される基地局である指定基地局の情報を予め記憶しておき、基地局情報比較手段１６へ出力する。 The base station information storage unit 17 described above stores in advance information on a designated base station that is a base station that the communication antenna 11 is permitted to use for communication, and outputs the information to the base station information comparison unit 16.
　上述の基地局情報比較手段１６は、基地局情報入力手段１５を介して基地局情報取得手段１３から入力した情報と、基地局情報記憶手段１７に記憶された情報とを比較し、使用基地局が指定基地局と一致しているか否かを判断し、判断結果を機械起動ロック手段３５へ出力する。 The base station information comparison means 16 compares the information input from the base station information acquisition means 13 via the base station information input means 15 with the information stored in the base station information storage means 17, and uses the base station information Is coincident with the designated base station, and the determination result is output to the machine activation lock means 35.
　上述の電波状態確認手段１９は、通信アンテナ１１の電波状態が良好か否かを判断し、その判断結果を機械起動ロック手段３５へ出力する。 The above-described radio wave state confirmation unit 19 determines whether or not the radio wave state of the communication antenna 11 is good, and outputs the determination result to the machine activation lock unit 35.
　上述の通信状態確認手段２０は、通信モジュール１２の通信状態が良好か否かを判断し、その判断結果を機械起動ロック手段３５へ出力する。 The above-described communication state confirmation unit 20 determines whether or not the communication state of the communication module 12 is good, and outputs the determination result to the machine activation lock unit 35.
　上述の機械起動ロック手段３５は、基地局情報比較手段１６において、使用基地局が指定基地局と一致していないと判断されると、工作機械１０が移設されたものとし、後述する通り、工作機械１０の起動制限を行い、ＮＣ装置９のパスワード入力機能のみを起動可能とし、規定値未満の入力回数で正確なパスワードが入力されれば起動制限を解除し、規定値未満の入力回数で正確なパスワードが入力されなければ、工作機械１０の起動停止を行う。 When the base station information comparing means 16 determines that the base station used does not match the designated base station, the machine activation lock means 35 is assumed to have been moved to the machine tool 10 and, as will be described later, Restricts the start of the machine 10 so that only the password input function of the NC device 9 can be started. If an accurate password is input with a number of inputs less than the specified value, the start restriction is canceled and the number of inputs less than the specified value is accurate. If the correct password is not entered, the machine tool 10 is started and stopped.
　さらに機械起動ロック手段３５は、電波状態確認手段１９において通信アンテナ１１の電波状態が良好でないと判断した場合または通信状態確認手段２０において通信モジュール１２の通信状態が良好でないと判断した場合においても、工作機械１０の起動停止を行う。 Further, the machine activation lock unit 35 also determines when the radio wave state confirmation unit 19 determines that the radio wave state of the communication antenna 11 is not good or when the communication state confirmation unit 20 determines that the communication state of the communication module 12 is not good. The machine tool 10 is started and stopped.
　上述の機械起動ロック解除手段８は、機械起動ロック手段３５による工作機械１０の起動停止を解除し、工作機械１０を起動させる。その方法は２通りで、１つはＮＣ装置９に直接出力して起動させる方法、２つには基地局情報変更手段１８を用いて指定基地局を変更する方法である。 The above-described machine start lock release means 8 releases the start / stop of the machine tool 10 by the machine start lock means 35 and starts the machine tool 10. There are two methods, one is a method in which the NC device 9 is directly output and activated, and the other is a method in which the designated base station is changed using the base station information changing means 18.
　上述の基地局情報変更手段１８は、機械起動ロック解除手段８から工作機械１０の起動停止解除の情報を入力すると、基地局情報記憶手段１７の指定基地局の情報を、基地局情報入力手段１５から入力した使用基地局の情報と一致させるものである。これにより、機械起動ロック手段３５において工作機械１０が移設されていないものとすることで、機械起動ロック手段３５によるＮＣ装置９の起動停止を解除し、工作機械１０を起動させることができる。 When the base station information changing means 18 receives the information about the start / stop release of the machine tool 10 from the machine start lock releasing means 8, the base station information input means 15 It matches with the information of the used base station input from. Thereby, it is assumed that the machine tool 10 is not moved in the machine activation lock unit 35, so that the activation stop of the NC device 9 by the machine activation lock unit 35 can be released and the machine tool 10 can be activated.
　以下、本装置の動作を図２のフローチャートを用いて説明する。 Hereinafter, the operation of this apparatus will be described with reference to the flowchart of FIG.
　ステップＳ１１では、基地局情報取得手段１３により、通信モジュール１２から使用基地局情報を取得する。 In step S11, the base station information acquisition means 13 acquires the used base station information from the communication module 12.
　ステップＳ１２では、基地局情報比較手段１６により、基地局情報入力手段１５を介して基地局情報取得手段１３から入力した使用基地局の情報と、基地局情報記憶手段１７に記憶された指定基地局の情報とを比較し、使用基地局に変更が無いか否か、つまり工作機械１０が移設されていないか否かを判断する。変更なしと判断すればステップＳ１８へ、そうでなければステップＳ１３へ移行する。 In step S12, the base station information comparison unit 16 uses the base station information input unit 15 to input the base station information input from the base station information acquisition unit 13, and the designated base station stored in the base station information storage unit 17 And whether or not the base station in use is changed, that is, whether or not the machine tool 10 has been relocated is determined. If it is determined that there is no change, the process proceeds to step S18, and if not, the process proceeds to step S13.
　ステップＳ１３では、基地局情報比較手段１６から使用基地局が変更されたとの情報が機械起動ロック手段３５に入力されると、機械起動ロック手段３５は工作機械１０が移設されたものとし、工作機械１０内のＮＣ装置９へ起動制限をかけ、パスワード入力機能のみが作動するようにする。 In step S13, when information indicating that the base station to be used has been changed from the base station information comparison means 16 is input to the machine activation lock means 35, the machine activation lock means 35 is assumed to have been moved to the machine tool 10, and the machine tool The activation restriction is applied to the NC device 9 in 10 so that only the password input function is activated.
　ステップＳ１４では、ＮＣ装置９でのパスワード入力において、入力回数が規定値以上か否かを判断する。規定値以上であればステップＳ１５へ、規定値未満であればステップＳ１６へ移行する。 In step S14, it is determined whether or not the number of times of input in the NC device 9 is greater than or equal to a specified value. If it is equal to or greater than the specified value, the process proceeds to step S15, and if it is less than the specified value, the process proceeds to step S16.
　ステップＳ１５では、機械起動ロック手段３５によって、工作機械１０の起動停止を行う。（但し、上述のように、機械起動ロック解除手段８により起動することが可能である。） In step S15, the machine start lock means 35 starts and stops the machine tool 10. (However, as described above, it can be activated by the machine activation lock releasing means 8.)
　ステップＳ１６及びステップＳ１７には、ＮＣ装置９におけるパスワードの入力回数が規定値未満のときに移行され、ステップＳ１７ではパスワードが正確に入力されているか否かを判断する。パスワードが正確に入力されていればステップＳ１８へ、そうでなければステップＳ１４へ移行する。 Step S16 and Step S17 are shifted to when the password input count in the NC device 9 is less than the specified value, and in Step S17, it is determined whether or not the password is correctly input. If the password is correctly input, the process proceeds to step S18, and if not, the process proceeds to step S14.
　ステップＳ１８では、機械起動ロック手段３５による工作機械１０の起動制限または起動停止を解除し、工作機械１０の起動を行う。 In step S18, the start restriction or the start / stop of the machine tool 10 by the machine start lock means 35 is released, and the machine tool 10 is started.
　ステップＳ１９では、電波状態確認手段１９により、通信アンテナ１１の電波状態を取得する。 In step S19, the radio wave condition confirmation means 19 acquires the radio wave condition of the communication antenna 11.
　ステップＳ２０では、電波状態確認手段１９により、通信アンテナ１１の電波状態が良好か否かを判断する。良好と判断されればステップＳ１８へ、そうでなければステップＳ１５へ移行する。 In step S20, the radio wave state confirmation means 19 determines whether or not the radio wave state of the communication antenna 11 is good. If it is determined to be good, the process proceeds to step S18, and if not, the process proceeds to step S15.
　ステップＳ２１では、通信状態確認手段２０により、通信モジュール１２の通信状態を取得する。 In step S21, the communication status of the communication module 12 is acquired by the communication status confirmation means 20.

　上述の通信システム１４、基地局情報入力手段１５、基地局情報変更手段１８、電波状態確認手段１９、通信状態確認手段２０及び機械起動ロック解除手段８は、実施例１に係る装置と同様であるため、説明は省略する。 The communication system 14, the base station information input unit 15, the base station information change unit 18, the radio wave state confirmation unit 19, the communication state confirmation unit 20, and the machine activation lock release unit 8 described above are the same as those in the apparatus according to the first embodiment. Therefore, explanation is omitted.
　上述の基地局情報比較手段３６、基地局情報記憶手段３７及び機械起動ロック手段５５も、基本的には実施例１に係る装置と同様である。但し、これらの手段で扱う指定基地局は１箇所ではなく、使用基地局が跨る可能性のある複数箇所の基地局とする。 The above-described base station information comparison unit 36, base station information storage unit 37, and machine activation lock unit 55 are basically the same as those in the apparatus according to the first embodiment. However, the number of designated base stations handled by these means is not one, but a plurality of base stations that may be used by the base stations used.
　即ち、基地局情報記憶手段３７は、上述の複数箇所の指定基地局の情報を予め記憶しておき、基地局情報比較手段３６へ出力する。 That is, the base station information storage unit 37 stores information on the designated base stations at a plurality of locations in advance and outputs the information to the base station information comparison unit 36.
　基地局情報比較手段３６は、基地局情報入力手段１５を介して基地局情報取得手段１３から入力した情報と、基地局情報記憶手段３７に記憶した情報とを比較し、使用基地局と上述の複数箇所の指定基地局とが一致しているか否かを判断する。その際、使用基地局が複数箇所の指定基地局のいずれか１箇所と一致していれば、使用基地局と指定基地局が一致しているものとする。そして、判断結果を機械起動ロック手段５５へ出力する。 The base station information comparison means 36 compares the information input from the base station information acquisition means 13 via the base station information input means 15 with the information stored in the base station information storage means 37, and compares the base station used with the above-mentioned base station. It is determined whether or not a plurality of designated base stations match. At this time, if the used base station matches any one of a plurality of designated base stations, it is assumed that the used base station matches the designated base station. Then, the determination result is output to the machine activation lock means 55.
　機械起動ロック手段５５は、基地局情報比較手段３６において、使用基地局と工作機械１０が跨る複数箇所の指定基地局とが一致していないと判断されると、工作機械１０が移設されたものとし、後述する通り、工作機械１０の起動制限を行い、ＮＣ装置９のパスワード入力機能のみを起動可能とし、規定値未満の入力回数で正確なパスワードが入力されれば起動制限を解除し、規定値未満の入力回数で正確なパスワードが入力されなければ、工作機械１０の起動停止を行う。 When the base station information comparison unit 36 determines that the machine base 10 is relocated, the machine activation lock unit 55 is relocated to the machine tool 10 when the base station information comparison unit 36 determines that a plurality of designated base stations across the machine tool 10 do not match. As described later, the activation of the machine tool 10 is restricted, and only the password input function of the NC device 9 can be activated. If an accurate password is input with a number of inputs less than the specified value, the activation restriction is canceled, and the regulation If an accurate password is not input with the number of inputs less than the value, the machine tool 10 is started and stopped.
　さらに機械起動ロック手段５５は、実施例１，２に係る装置と同様、電波状態確認手段１９において通信アンテナ１１の電波状態が良好でないと判断した場合または通信状態確認手段２０において通信モジュール１２の通信状態が良好でないと判断した場合においても、工作機械１０の起動停止を行う。 Further, the machine activation lock unit 55, like the devices according to the first and second embodiments, performs communication of the communication module 12 when the radio wave state confirmation unit 19 determines that the radio wave state of the communication antenna 11 is not good or the communication state confirmation unit 20 performs communication. Even when it is determined that the state is not good, the machine tool 10 is started and stopped.

To determine whether there is any change. At this time, if the used base station matches any one of the above-mentioned designated base stations, it is determined that there is no change, and the used base station must match any of the designated base stations. If so, the process proceeds to step S53.
　ステップＳ５３では、基地局情報比較手段３６から使用基地局が変更されたとの情報が機械起動ロック手段５５に入力されると、機械起動ロック手段５５は工作機械１０が移設されたものとし、工作機械１０内のＮＣ装置９へ起動制限をかけ、パスワード入力機能のみが作動するようにする。 In step S53, when information indicating that the base station to be used has been changed is input from the base station information comparison unit 36 to the machine activation lock unit 55, the machine activation lock unit 55 assumes that the machine tool 10 has been moved. The activation restriction is applied to the NC device 9 in 10 so that only the password input function is activated.
　ステップＳ５４では、ＮＣ装置９でのパスワード入力において、入力回数が規定値以上か否かを判断する。規定値以上であればステップＳ５５へ、規定値未満であればステップＳ５６へ移行する。 In step S54, it is determined whether or not the number of times of input in the NC device 9 is greater than or equal to a specified value. If it is equal to or greater than the specified value, the process proceeds to step S55, and if it is less than the specified value, the process proceeds to step S56.
　ステップＳ５５では、機械起動ロック手段５５によって、工作機械１０の起動停止を行う。（但し、機械起動ロック解除手段８により起動することが可能である。） In step S55, the machine activation lock means 55 is used to start and stop the machine tool 10. (However, it can be activated by the machine activation lock release means 8.)
　ステップＳ５６及びステップＳ５７には、ＮＣ装置９におけるパスワードの入力回数が規定値未満のときに移行され、ステップＳ５７ではパスワードが正確に入力されているか否かを判断する。パスワードが正確に入力されていればステップＳ５８へ、そうでなければステップＳ５４へ移行する。 Step S56 and Step S57 are shifted to when the number of times the password is input in the NC device 9 is less than the specified value, and in Step S57, it is determined whether or not the password is correctly input. If the password is correctly input, the process proceeds to step S58, and if not, the process proceeds to step S54.
　ステップＳ５８では、機械起動ロック手段５５による工作機械１０の起動制限または起動停止を解除し、工作機械１０の起動を行う。 In step S58, the start restriction or the start / stop of the machine tool 10 by the machine start lock means 55 is released, and the machine tool 10 is started.
　ステップＳ５９乃至Ｓ６２は、実施例１，２に係る装置と同様であるため省略する。 Steps S59 to S62 are the same as those of the apparatus according to the first and second embodiments, and thus are omitted.

If there is a possibility that the station has been changed and the machine tool has been relocated, the relocation detection is performed only when the designated base stations are stored in advance and it is determined that the used base station does not match any of them. By operating the system, the malfunction as described above can be prevented.
