Description

특정 작업자를 인식하는 전동 공구Power tool to recognize a specific operator
본 발명은 내장되는 전동 모터 등의 토크를 이용하여 천공 작업, 너트에 대한 체결 작업 등 각 종 전동 작업을 수행할 수 있는 전동 공구에 관한 것이다.The present invention relates to a power tool capable of performing various electric power operations such as drilling work, fastening work for a nut, and the like by using a torque of a built-in electric motor.
과거 전동 공구는 조임, 드릴링 등 본연의 기능이나 작업자에 대한 안전 성능 등을 향상시키는 방향으로 개발되어 왔다. 그 후, 개발 방향은 작업자의 사용 편의성이나 작업 효율을 도모함에 초점이 맞춰졌다. 최근, 스마트폰 관련 기술의 급격한 발전에 따라 어느 산업 분야를 막론하고 스마트 기술을 해당 제품에 접목시키려는 시도가 활발해지고 있다.In the past, power tools have been developed to improve the original functions such as tightening and drilling, and safety performance for the operator. Since then, the development direction has been focused on the ease of use of the operator and the work efficiency. Recently, due to the rapid development of smartphone-related technology, attempts to integrate smart technology into the corresponding products in any industry field have been actively made.
이를 특히 산업 현장에서 사용되는 전동 공구에 적용하면, 작업장 내에는 전동 공구의 사용과 관련되는 다양한 문제점이 있었다. 예를 들어, 작업장 내의 전체 작업 스케쥴에는 작업 내용에 따라 전동 공구 별로 작업자가 지정되어 있다. 그 결과, 지정된 작업자 이외의 작업자가 해당 전동 공구를 사용하게 되면 작업 불량 등이 발생되는 문제점이 발생할 수 있다.In particular, when applied to the power tool used in industrial sites, there were various problems related to the use of the power tool in the workplace. For example, the entire work schedule in the workplace is assigned a worker for each power tool according to the work content. As a result, when an operator other than the designated operator uses the power tool, a problem such as a work failure may occur.
또한, 작업자 중 일부는 할당된 작업 시간이 종료되면 전동 공구를 지정된 작업 라인이 아닌 다른 장소에 갖다 두는 경향이 있다. 이는, 그 이후 다른 작업자가 원래 지정된 전동 공구가 아닌 다른 전동 공구를 무의식 중에 사용하는 등의 이유로 작업 불량을 발생시킬 수 있다.In addition, some of the workers tend to place the power tool in a place other than the designated work line at the end of the assigned work time. This may then cause work failures, for example, when another operator unconsciously uses a power tool other than the originally designated power tool.
또한, 초보 작업자는 순차적으로 이동하며 작업해야 하는 작업 라인 즉 작업 경로 등에 대해 혼동하는 실수를 종종 일으켰다. 즉, 작업자는 관리자가 사전에 미리 지정한 작업 라인을 이탈하여 다른 작업 라인 등으로 이동하는 등의 이유로 작업 불량을 일으켰다.In addition, novice workers have often made confusing mistakes about work lines, ie work paths, which must be moved in sequence. That is, the worker has caused work defects, for example, by moving away from the work line previously designated by the administrator and moving to another work line.

In addition, if any one of the various locking conditions are satisfied, the automatic locking can be used to limit the use of the power tool. In addition, not only by the operator, but also by the administrator managing the workplace, the power tool can be controlled to be locked or unlocked.
또한, 작업 라인이 변경되면 자동적으로 그 작업 라인에 맞게 각 종 공구의 설정값이 변경될 수 있도록 한다. 또한, 전동 공구에 현재 작업장 내 위치와 다양한 작업 정보 등을 표시할 수 있는 디스플레이부를 통해 작업 효율을 향상시키고자 한다.In addition, when the work line is changed, the set values of various tools can be changed automatically to match the work line. In addition, to improve the work efficiency through a display unit that can display the current location and various work information on the power tool.

In addition, the operator can be identified to automatically change the set value of the power tool to suit each operator.
또한, 전동 공구는 다양한 잠금조건에 대해 자동적으로 잠금되어 작업 불량 등의 발생을 차단할 수 있다. 한편, 전동 공구는 무선통신모듈을 더 포함하여 관리자에 의해 잠금조건이 업데이트되면 그 즉시 동기화될 수 있다.In addition, the power tool is automatically locked for various locking conditions can block the occurrence of work failures.

한편, 전동 공구는 위치추적센서를 더 포함하여 전동 공구의 현재 위치 정보를 작업자에게 제공할 수 있으며, 이런 위치 정보는 작업장을 구분하는 존영역에 대해 텍스트 형태로 제공되어 작업자의 빠른 인식에 도움을 준다. 또한, 작업 경로에 따라 전동 공구의 위치가 변경되면 그 위치 변경을 인식하여 작업별세팅값이 자동적으로 변경된다.On the other hand, the power tool may further include a position tracking sensor to provide the operator with the current position information of the power tool, and such position information is provided in a text form for the zone area that separates the workplace to help the operator quickly recognize. give. In addition, when the position of the power tool is changed according to the work path, the position change value is recognized and the setting value for each work is automatically changed.
또한, 디스플레이부는 작업 대상물의 표면 등에 작업 정보를 생성할 수 있어 작업자가 전동 작업이나 전동 공구의 상태를 용이하게 파악할 수 있도록 한다.In addition, the display unit may generate work information on the surface of the work object and the like so that an operator may easily grasp the state of the power work or the power tool.

이하, 도면을 참조하여 본 발명의 구체적인 실시예를 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
도 1은 본 발명의 일 실시예에 따른 전동 공구를 도시한 개략도이고, 도 2는 도 1의 전동 공구에 대한 위치 추적과 무선 통신을 위한 시스템의 개략도이다. 도 1 및 도 2를 참조하면, 특정 작업자를 인식하는 전동 공구는 작업자인식모듈(20), 잠금모듈(30), 위치추적센서(40), 디스플레이부(50), 메모리부(60), 무선통신모듈(70), 작업자환경로딩부(80) 등을 더 포함한다. 여기서, 전동 공구는 내장되는 전동기 예를 들어, 전기모터(10) 등의 축 회전력을 이용하여 토크를 발생시키고 이를 이용하여 너트의 체결 등 각 종 전동 작업을 수행할 수 있는 모든 종류를 망라한다.1 is a schematic diagram illustrating a power tool according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of a system for location tracking and wireless communication for the power tool of FIG. 1. 1 and 2, the power tool for recognizing a particular worker is a worker recognition module 20, lock module 30, position tracking sensor 40, display 50, memory 60, wireless Communication module 70, the operator environment loading unit 80, and the like further. Here, the electric tool covers all kinds of electric motors, for example, an electric motor 10, which generates torque by using axial rotational force, and performs various electric power operations such as fastening of nuts by using the same.
일 실시예에 따른 전동 공구는 본연의 전동 작업을 수행하기 위해 존재하던 구성 요소 이외에 특정 작업자를 인식하여 잠금 상태를 전환시키는 기능, 전동 공구의 위치를 추적하고, 전동 공구와 통신하는 기능 등을 구현하기 위해 전술한 구성 요소를 더 필요로 한다.The power tool according to an embodiment implements a function of recognizing a specific operator to switch the lock state, tracking the position of the power tool, and communicating with the power tool, in addition to the components existing to perform the original power work. In order to do so, the above-described components are further needed.
작업자인식모듈(20)은 작업자에 대한 정보를 추출하여 추출된 정보를 통해 작업자가 미리 등록된 작업자와 합치하면 인증신호를 생성시킨다. 작업자인식모듈(20)은 작업자에 대한 지문 정보를 추출하는 지문인식모듈, 작업자에 대한 홍채 정보를 추출하는 홍채인식모듈 및 미리 등록된 작업자에 한해 부여되는 비밀번호 정보를 추출하는 번호인식모듈 중 어느 하나인 것이 바람직하다.The worker recognition module 20 extracts information about the worker and generates an authentication signal when the worker matches the worker registered in advance through the extracted information. The worker recognition module 20 may be any one of a fingerprint recognition module for extracting fingerprint information of a worker, an iris recognition module for extracting iris information for a worker, and a number recognition module for extracting password information given only to a pre-registered worker. Is preferably.
지문인식모듈은 인체에 대한 생체 정보 중 하나인 지문 정보를 추출한다. 이는 종래 보편적으로 사용되던 사용자 인증 기술 중 하나이다. 홍채인식모듈은 인체에 대한 생체 정보 중 또 다른 하나인 홍채 정보를 추출한다. 홍채 정보는 홍채의 모양이나 색깔, 망막에 분포하는 모세혈관 등을 분석하여 사람을 식별하기 위한 수단으로 사용되어 왔다. 홍채 정보는 지문 정보보다 더 많은 개인별 고유 특성을 갖고 있어 안경이나 렌즈를 착용하더라도 정확하게 개개인을 인식할 수 있다. 또한, 홍채인식모듈은 지문인식모듈과 달리 비접촉 방식으로 작동되는 장점을 갖는다.The fingerprint recognition module extracts fingerprint information which is one of biological information about a human body. This is one of the user authentication techniques used in the prior art. The iris recognition module extracts iris information, which is another one of biological information about the human body. Iris information has been used as a means to identify people by analyzing the shape and color of the iris and capillaries distributed in the retina. The iris information has more individual characteristics than fingerprint information, so even when wearing glasses or lenses, the iris information can be accurately recognized. In addition, the iris recognition module has an advantage of operating in a non-contact manner, unlike the fingerprint recognition module.
번호인식모듈은 미리 등록된 작업자에 한해 부여되는 비밀번호 정보를 추출한다. 즉, 비밀번호는 특정 작업자에 한해 노출되어 전동 공구에 대한 사용 권한이 특정 작업자에 국한되도록 한다. 번호인식모듈은 예를 들어, 숫자 등이 표시된 버튼부를 포함하며 이는 시중에 유통되는 비밀번호키 장치와 유사하다. 즉, 번호인식모듈은 비밀번호를 부여받은 특정 작업자가 직접 비밀번호를 입력할 수 있도록 전동 공구에 형성된다.The number recognition module extracts password information given only to the registered worker. That is, the password is exposed only to a specific operator so that the authority to use the power tool is limited to the specific operator. The number recognition module includes, for example, a button portion in which numbers and the like are displayed, which is similar to a commercially available encryption key device. That is, the number recognition module is formed in the power tool so that a specific operator who is given a password can directly input the password.
작업자인식모듈(20)은 전동 공구의 본체 등에 외부로 노출되게 배치되어 작업 전 해당 전동 공구를 배정받은 작업자로 하여금 자신이 미리 등록된 특정 작업자 중 어느 한 명과 합치하는지 여부를 미리 확인 받도록 한다. 즉, 작업자인식모듈(20)은 미리 등록된 작업자에 한해 해당 전동 공구에 대한 사용 허락을 득하여 비로소 전동 작업을 수행할 수 있게 한다.The worker recognition module 20 is disposed to be exposed to the outside of the main body of the power tool, so that the worker who is assigned the power tool before the operation checks in advance whether or not it matches with any one of a specific worker registered in advance. That is, the worker recognition module 20 can perform the electric work only after obtaining a permission for use of the power tool only for the registered operator.
잠금모듈(30)은 인증신호가 수신되면 전동 공구를 잠금 해제시키고, 인증신호가 미수신되면 전동 공구의 잠금 상태를 유지시킨다. 이런 잠금이나 잠금 해제는 소프트웨어나 하드웨어 방식을 통해 전동 공구의 전원을 차단하는 등의 방법으로 구현될 수 있다.The lock module 30 releases the power tool when the authentication signal is received, and maintains the lock state of the power tool when the authentication signal is not received. Such locking or unlocking may be implemented by switching off the power tool via software or hardware.
잠금모듈(30)은 미리 설정되는 적어도 하나 이상의 잠금조건을 저장하는 메모리부(60)를 더 포함할 수 있다. 메모리부(60)는 종래 전동 공구에 내장되어 사용되던 메인메모리일 수 있고, 이와 달리 작업자인식모듈(20)과 잠금모듈(30)과 관련된 데이터만 저장할 수 있는 전용 보조메모리일 수 있다.The lock module 30 may further include a memory unit 60 for storing at least one lock condition set in advance. The memory unit 60 may be a main memory used in a conventional power tool, or alternatively, may be a dedicated auxiliary memory capable of storing only data related to the worker recognition module 20 and the lock module 30.
보조메모리인 경우 메모리부(60)는 전동 공구의 본체에 내장될 수 있고, 이와 달리 용량 확장이 가능하며 탈착 가능한 외장 메모리 카드 형태일 수 있다. 예를 들어, 메모리부(60)는 sd 카드, micro sd 카드 등일 수 있다.In the case of the auxiliary memory, the memory unit 60 may be built in the main body of the power tool. Alternatively, the memory unit 60 may have a capacity expansion and a removable external memory card. For example, the memory unit 60 may be an sd card, a micro sd card, or the like.
메모리부(60)에 저장되는 잠금조건은 1) 시각에 따라 미리 설정되는 각각의 작업 라인을 이탈하였는지 여부, 2) 허락된 작업 종료 시간을 초과하였는지 여부, 3) 작업자 별로 일일 허용되는 전체 작업 시간을 초과하였는지 여부 및 4) 미리 설정된 횟수만큼 작업 불량이 연속적으로 발생하였는지 여부 중 어느 하나일 수 있다. 이를 위해, 전동 공구는 세계 표준 시간 등과 동기화될 수 있다. 한편, 잠금모듈(30)은 전술한 잠금조건이 충족되면 전동 공구를 잠금시킨다.The lock condition stored in the memory unit 60 is 1) whether or not each job line is set in advance according to the time, 2) whether the allowed work end time is exceeded, and 3) the total work time allowed per worker per day. And 4) whether a work failure occurs continuously a predetermined number of times. For this purpose, the power tool can be synchronized with world standard time and the like. On the other hand, the locking module 30 locks the power tool when the above-described locking condition is satisfied.
작업장 내의 전동 공구는 각 전동 공구 별로 시각에 따라 미리 설정된 작업 라인에서 전동 작업이 이루어지도록 계획되어 있다. 따라서, 전동 공구가 특정 시각에 해당 작업 라인을 이탈하는 경우 잠금조건이 충족되며 전동 공구는 자동적으로 잠금된다. 이 때, 전동 공구가 작업 라인을 이탈하였는지 여부는 위치추적센서(40)를 통해 구현될 수 있다.The power tools in the workplace are planned to perform the power work in the work line which is preset according to the time for each power tool. Therefore, when the power tool leaves the work line at a specific time, the locking condition is satisfied and the power tool is automatically locked. In this case, whether the power tool has left the work line may be implemented through the position tracking sensor 40.
작업자의 일일 작업 시간은 법규 규정 등을 고려하여 결정한다. 이를 근거로 작업자의 작업 시작 시간과 작업 종료 시간이 각각 조절된다. 이 때, 일 실시예에 따른 잠금조건은 특히 작업 종료 시간을 그 기준으로 한다.The worker's daily working time is determined by considering the regulations. Based on this, the work start time and the work end time of the worker are respectively adjusted. In this case, the locking condition according to the embodiment is based on the job end time.
또한, 작업자 별로 일일 허용되는 총 작업 시간이 제한될 수 있다. 교대 근무 등의 이유로 작업 중간에 작업자가 변경되는 경우에도 등록된 작업자는 작업자인식모듈(20)을 통해 잠금 상태를 해제할 수 있는 바, 자신에게 할당된 전동 작업을 할 수 있다. 즉, 전동 공구는 작업자 별로 일일 누적되는 총 작업 시간을 산출하여 허용되는 총 작업 시간을 초과하였는지 여부에 따라 전동 공구를 잠금하여 그 사용을 제한할 수 있다.In addition, the total work time allowed per worker may be limited. Even if the worker is changed in the middle of the work due to shift work, the registered worker can release the lock state through the worker recognition module 20, so that the electric work assigned to the worker can be performed. That is, the power tool may calculate the total work time accumulated for each worker to limit the use of the power tool by locking the power tool depending on whether the total work time allowed is exceeded.
또한, 작업자는 작업 도중 부주의, 실수 등에 의한 작업 불량을 초래할 수 있다. 그러나, 단발적 실수에 대해서도 전동 공구가 즉시 잠김되면 작업장의 생산성이 저하되는 문제점이 발생할 수 있다. 따라서, 전동 공구는 작업 불량이 미리 설정된 횟수만큼 연속적으로 발생되는 경우에 한해 자동 잠금되도록 한다.In addition, the worker may cause work failure due to carelessness, mistake, etc. during the work. However, even if a single mistake is immediately locked the power tool may be a problem that the productivity of the workplace is reduced. Therefore, the power tool is to be automatically locked only when a work failure occurs continuously a predetermined number of times.
이상 전술한 잠금조건은 복수 개의 구체적인 예시를 열거한 것에 불과할 뿐, 반드시 이에 한정되는 것은 아니다. 즉, 전술한 잠금조건 이외에 전동 공구는 작업장 내의 복수의 작업자를 관리하는 관리자에 의한 임의적 판단이나, 작업장 내에서 발생하는 예상치 못한 긴급 상황 등에 따라 잠김될 수 있다. 그러나, 이를 기술적으로 구현하기 위해서는 전동 공구는 통신 가능한 무선통신모듈(70) 등을 더 포함해야 한다.The above-described locking condition is merely listed a plurality of specific examples, but is not necessarily limited thereto. That is, in addition to the above-described locking condition, the power tool may be locked according to an arbitrary judgment by an administrator who manages a plurality of workers in the workplace or an unexpected emergency occurring in the workplace. However, in order to technically implement this, the power tool should further include a wireless communication module 70 for communication.
전동 공구는 작업장 내에 위치하는 메인서버부(100)와 무선 통신하는 무선통신모듈(70)을 더 포함할 수 있다. 즉, 작업장 내에 배치되는 복수 개의 전동 공구는 무선 네크워크에 의해 메인서버부(100)와 양방향 통신을 할 수 있다.The power tool may further include a wireless communication module 70 for wireless communication with the main server unit 100 located in the workplace. That is, the plurality of power tools disposed in the workplace may perform bidirectional communication with the main server unit 100 by a wireless network.
무선 통신은 예를 들어, 근거리통신에 대한 표준 기술인 블루투스나 지그비 등이 사용될 수 있다. 블루투스에 의한 데이터 전송거리는 표준에 정해진 파워 레벨에 따라 최대 100미터까지 지원된다. 한편, 지그비는 홈오토메이션 등을 구현하기 위한 표준 프로토콜로 블루투스와 같이 저비용, 저전력으로 무선 통신을 지원할 수 있다.For example, Bluetooth or ZigBee, which is a standard technology for short-range communication, may be used for wireless communication. The data transmission distance by Bluetooth is supported up to 100 meters depending on the power level specified in the standard. Meanwhile, Zigbee is a standard protocol for realizing home automation and the like and can support wireless communication at low cost and low power, such as Bluetooth.
이 때, 메모리부(60)는 무선통신모듈(70)을 통해 관리자에 의해 업데이트되는 새로운 잠금조건과 일치되도록 동기화될 수 있다. 잠금조건은 각 전동 공구 별로 일부 차이점이 있다. 그리고, 복수 개의 각 전동 공구에 대한 잠금조건을 변경하기 위해 일일이 각 전동 공구에 포함되는 메모리부(60)의 내용을 지우고 다시 새로운 내용을 기록 저장하는 것은 불편하고 번거롭다. 또한, 이런 방법은 작업 도중 급작스럽게 잠금조건이 변경되는 경우 신속하게 대처할 수 없다는 단점이 있다. 따라서, 일 실시예에 따른 메모리부(60)는 무선통신모듈(70)을 통해 신속하게 업데이트될 수 있도록 변경된다.At this time, the memory unit 60 may be synchronized to match the new lock condition updated by the administrator through the wireless communication module 70. There are some differences in locking conditions for each power tool. And, in order to change the lock condition for each of the plurality of power tools, it is inconvenient and cumbersome to erase the contents of the memory unit 60 included in each power tool and record new contents again. In addition, this method has a disadvantage in that it can not cope quickly if the lock condition is changed suddenly during the operation. Therefore, the memory unit 60 according to an embodiment is changed to be quickly updated through the wireless communication module 70.
잠금모듈(30)은 잠금조건이 충족되면 전동 공구를 잠금시키고, 잠금해제조건이 충족되면 잠금 상태를 해제시킬 수 있다. 잠금해제조건은 미리 설정된 복수 단계를 갖는 해제 과정을 작업자가 직접 실시하는지 여부, 관리자가 모니터링하는 각 전동 공구에 대해 메인서버부(100) 등을 이용하여 잠금 상태를 직접 해제하는지 여부 등을 포함한다.The locking module 30 may lock the power tool when the locking condition is satisfied, and release the locking state when the unlocking condition is satisfied. The unlocking condition includes whether the operator directly performs a release process having a plurality of preset stages, whether to directly release the lock state by using the main server unit 100, etc. for each power tool monitored by the administrator. .
한편, 작업자환경로딩부(80)는 작업자인식모듈(20)을 통해 인증되는 작업자를 식별하여 개별적인 각 공구설정값을 로딩시킨다. 즉, 작업자환경로딩부(80)는 인증 절차를 거친 작업자에 대한 작업자 환경 예를 들어, 작업자의 신체 조건 등의 개인적 특성이나 각 작업자에 할당된 작업 내용을 고려하여 이에 부합되는 공구설정값을 자동적으로 변경시킨다. 이런 설정값은 예를 들어 각 작업 공정에 최적화된 토크의 크기, 전동기의 회전 속도, 전동기로 유입되는 전류의 최소값과 최대값 등을 포함한다.On the other hand, the worker environment loading unit 80 identifies the operator to be authenticated through the worker recognition module 20 to load the respective tool setting value. That is, the worker environment loading unit 80 automatically calculates a tool setting value corresponding to the worker environment for the worker who has undergone the authentication procedure, for example, in consideration of personal characteristics such as the physical condition of the worker or work contents assigned to each worker. To. These settings include, for example, the amount of torque optimized for each work process, the rotational speed of the motor, the minimum and maximum values of current flowing into the motor, and so on.
또한, 전동 공구는 시간, 장소, 작업자의 변경, 관리자의 의도 등을 인식하고 공구설정값을 자동적으로 변경시킬 수 있다. 이는 후술할 위치추적센서(40)와 무선통신모듈(70)을 이용한 메인서버부(100)와의 통신 등에 의해 구현될 수 있다.In addition, the power tool can recognize the time, place, change of the operator, the intention of the administrator, and can automatically change the tool set value. This may be implemented by communication with the main server unit 100 using the position tracking sensor 40 and the wireless communication module 70 to be described later.
또한, 전동 공구는 메모리부(60)를 통해 일일 작업 중간에 작업 내용, 작업자의 변경 등과 관련되는 종합적인 작업 기록 등을 저장할 수 있다. 그 결과, 관리자는 각 작업자에 대한 작업 품질 등을 용이하게 관리할 수 있다.In addition, the power tool may store a comprehensive work record related to work contents, a change of an operator, etc. in the middle of daily work through the memory unit 60. As a result, the manager can easily manage work quality and the like for each worker.
한편, 일 실시예에 따른 전동 공구는 작업장 내부에서 전동 공구의 위치 정보를 검출하는 위치추적센서(40)를 더 포함할 수 있다. 위치추적센서(40)는 예를 들어, GPS센서일 수 있다. GPS(Global position system)는 지구 주위를 떠다니는 위성을 통해 위치를 확인하는 시스템이다. 이런 위치추적센서(40)는 근거리 및 실내와 같은 제한된 공간에서 전동 공구의 위치를 실시간 확인하고, 그 위치 변화를 추적할 수 있다. 위치추적센서(40)를 통해 실시간 전동 공구의 위치를 추적하기 위해서는 예를 들어, 작업장 내에 기지국(150)과 WiFi 네트워크를 추가적으로 배치하는 방법 등을 활용할 수 있다.On the other hand, the power tool according to an embodiment may further include a position tracking sensor 40 for detecting the position information of the power tool in the workplace. The position tracking sensor 40 may be, for example, a GPS sensor. GPS (Global position system) is a system that identifies the position through the satellites floating around the earth. The position tracking sensor 40 may check the position of the power tool in a limited space such as near and indoor in real time, and track the position change. In order to track the position of the real-time power tool through the position tracking sensor 40, for example, a method of additionally arranging the base station 150 and the WiFi network in the workplace may be utilized.
도 3은 도 1의 전동 공구가 어느 존영역 내에 위치하는 경우 디스플레이부를 도시한 개략도이다. 도 3을 참조하면, 전동 공구가 실제 배치 사용되는 작업장은 미리 설정되는 복수 개의 존(zone)영역(200)으로 구분되며, 이 때 위치추적센서(40)에서 검출되는 실측정위치는 존영역(200) 중 어느 하나로 전환되어 존위치로 표시되는 것이 바람직하다. 즉, 전동 공구는 실제 현위치 즉 실측정위치가 아닌 실측정위치가 속하는 존영역(200)에 대한 위치 정보를 제공한다. 한편, 존영역(200)은 존위치 형태로 표현된다.3 is a schematic diagram illustrating a display unit when the power tool of FIG. 1 is located in a zone area. Referring to FIG. 3, a workplace in which an electric tool is actually arranged and used is divided into a plurality of zone zones 200 which are set in advance, and the actual measurement position detected by the position tracking sensor 40 is determined by the zone zone ( It is preferable to switch to any one of 200) and display the zone position. That is, the power tool provides position information on the zone area 200 to which the actual measurement position, which is not the actual current position, that is, the actual measurement position belongs. On the other hand, the zone area 200 is expressed in the form of zone position.
존영역(200)은 작업장을 작업 라인의 배치, 작업자가 이동 가능한 허용 공간 등에 따라 관리자가 편의상 구분한 것에 해당된다. 이는 관리자 및 작업자 입장에서 전동 공구의 정확한 실제 위치 보다 현재 작업장 내의 어느 존영역(200)에 위치하는지에 대한 정보가 더 유용하기 때문이다.The zone area 200 corresponds to the division of the workplace for convenience by the manager according to the arrangement of the work line, the allowable space in which the worker can move, and the like. This is because the information on which zone area 200 in the current workplace is more useful than the exact actual position of the power tool from the manager and the operator.
이 때, 존위치는 특히 텍스트 형태로 디스플레이부(50)에 표시되는 것이 바람직하다. 텍스트는 작업자로 하여금 현재 존영역(200)을 신속하게 인식할 수 있도록 한다. 존위치에 대한 표기 방법은 예를 들어, A1, A2 등 영문자와 숫자를 혼합하여 표기한 형태일 수 있다. 그 결과, 초보 작업자는 현재 위치, 미리 설정되는 작업 경로에 맞게 자신이 제대로 이동하고 있는지 여부 등을 간명하게 파악할 수 있다. 한편, 디스플레이부(50)는 현재 존위치에 대한 정보만을 표시할 수 있고, 전체 작업 경로 등을 포함하여 표시할 수도 있다.At this time, the zone position is preferably displayed on the display unit 50 in the form of text. The text allows the operator to quickly recognize the current zone area 200. The notation method for the zone location may be, for example, a combination of alphabets and numbers such as A1 and A2. As a result, the novice worker can easily grasp whether he is moving properly according to the current position, the preset work path, and the like. On the other hand, the display unit 50 may display only the information on the current zone position, it may be displayed including the entire work path.
한편, 전동 공구에는 미리 설정되는 적어도 하나 이상의 작업별설정값이 저장될 수 있다. 작업별설정값은 예를 들어 메모리부(60) 등에 저장된다. 작업별설정값은 작업 경로 즉, 장소에 따라 달라지는 작업 내용을 고려하여 변경되어야 하는 각 종 설정값을 포함한다. 이런 작업별설정값은 존위치가 변경되면 변경되는 존영역(200)의 작업 내용에 맞춰 자동적으로 변경될 수 있다. 따라서, 작업자는 어느 일 존영역(200)에서 다른 존영역(200)으로 이동하는 경우 일일이 그 설정값을 변경할 필요가 없게 된다.On the other hand, the power tool may be stored at least one job-specific setting value which is set in advance. The setting value for each job is stored in, for example, the memory unit 60 and the like. The setting values for each job include various setting values that should be changed in consideration of the work path, that is, the work content that varies depending on the location. This job-specific setting value may be automatically changed in accordance with the job contents of the zone area 200 to be changed when the zone position is changed. Therefore, when a worker moves from one zone area 200 to another zone area 200, the worker does not need to change the set value one by one.
디스플레이부(50)는 전동 공구에 대한 작업 정보를 표시한다. 디스플레이부(50)는 예를 들어, 전동 공구의 본체에 배치되는 일반적인 액정표시장치(LCD)일 수 있다. 한편, 작업자는 숙련도에 따라 작업 정보에 대한 관심 정도가 다른 바, 디스플레이부(50)는 작업자에 따라 다른 작업 정보를 제공하는 것이 바람직하다.The display unit 50 displays job information on the power tool. The display unit 50 may be, for example, a general liquid crystal display (LCD) disposed on the main body of the power tool. On the other hand, the degree of interest in the job information is different depending on the skill of the operator, the display unit 50 preferably provides different job information according to the operator.
예를 들어, 초보 작업자는 현재 자신이 위치하는 존영역(200), 해당 존영역(200)에 따른 작업 내용, 그 다음 이동해야 할 존영역(200)을 포함하는 전체 작업 경로 등에 대한 정보를 필요로 한다. 반면, 숙련된 작업자는 현재 작업의 진행 정도, 일일 총 작업량에 대한 현재 상황 체크 등에 대한 정보를 더 필요로 한다.For example, a novice worker needs information on the zone area 200 where he is currently located, the work contents according to the zone area 200, and the entire work path including the zone area 200 to be moved next. Shall be. The skilled worker, on the other hand, needs more information about the progress of the current work, the current status check on the total daily work load, and the like.
다만, 디스플레이부(50)는 제한적인 크기로 인해 모든 작업 내용에 대한 정보를 일괄하여 표시할 수 없다. 따라서, 디스플레이부(50)는 작업 내용에 대한 정보를 선별적으로 표시할 수 있는 선택버튼부(미도시)를 더 포함할 수 있다.However, the display unit 50 may not collectively display information on all work contents due to the limited size. Therefore, the display unit 50 may further include a selection button unit (not shown) that can selectively display information on the work content.
도 4a와 도 4b는 다른 실시예에 따른 디스플레이부에 대한 개략도이다. 도 4a 및 도 4b를 참조하면, 디스플레이부(50)는 일반적인 액정표시장치와 달리 작업 대상물의 표면에 직접 작업 정보를 생성시키는 가상의 이미지 장치로 이루어질 수 있다. 이런 경우 디스플레이부(50)는 작업 정보에 따라 간단하게 확인 가능한 예를 들어, 작업 진행도나 작업 불량 여부를 표시할 수 있다. 또는 작업 대상물의 표면 상태가 불규칙하거나 복잡하여 작업 정보를 생성하기 어려운 경우에는 바(bar)(도 4-1 참조)나 링(ring)(도 4-2 참조) 형태의 간단한 시각적 표현으로 작업 정보를 생성 표시할 수 있다.4A and 4B are schematic views of a display unit according to another exemplary embodiment. 4A and 4B, the display unit 50 may be a virtual image device that directly generates work information on a surface of a work object unlike a general liquid crystal display device. In this case, the display unit 50 may display, for example, work progress or work failure, which can be easily checked according to work information. Or, if the surface state of the work object is irregular or complicated, making it difficult to generate the work information, the work information is expressed in a simple visual representation in the form of a bar (see Fig. 4-1) or a ring (see Fig. 4-2). Can be created and displayed.
이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는 것은 아니며, 특허청구범위에 기재된 범주 내에서 적절하게 변경 가능한 것이다.Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
