More specifically, in the case of the work that requires the vertical, when the operator cannot see the measured angle directly with the naked eye, the measured result is wirelessly transmitted to the place where the worker is located and the operator checks the measured data transmitted to the receiver. It relates to an angle measuring device that allows.
차수벽 설치공사, 심정(深井)굴착공사, 현장치기 말뚝(Cast in Place Pile)공사 등과 같이 땅속을 수직으로 깊이 파는 공사 또는 탑(Tower)이나 토목 건축공사와 같이 수직도를 항시 점검해야 할 경우에는 각도측정기를 밀폐된 곳이나 높은 굴착기, 탑, 시설물 등의 정상(頂上)에 부착하여야 하므로 측정자가 직접 각도측정기가 설치된 곳까지 접근하여 작업의 수직여부를 확인하기 어려운 실정이었다.If you need to check the verticality at all times, such as digging deep into the ground such as the water line wall installation work, deep excavation work, cast in place pile work, or tower or civil engineering work. Because the angle measuring device should be attached to the top of a closed place, high excavator, tower, facilities, etc., it was difficult for the measurer to approach the place where the angle measuring device was installed and to check the verticality of the work.
본 발명은 이러한 문제점을 해소하고자 하는 것으로 수직을 요하는 작업에 있어서 작업자가 접근하기 어려운 곳에 설치된 각도측정기까지 가지 않고도 편리하게 측정결과를 작업자가 위치하고 있는 곳에서 확인할 수 있게 하는데 목적이 있다.The present invention is to solve this problem is to make it possible to conveniently check the measurement results in the place where the operator is located without going to the angle measuring device installed in a place that is difficult for the operator in the work requiring the vertical.
이러한 목적을 달성하기 위하여 땅속이나 탑 또는 건축물 꼭대기 등 수직도를 측정하고자 하는 위치에 설치된 각도측정기의 각도센서부에서 측정된 각도측정신호를 작업자가 볼 수 있는 위치로 송신하고 송신된 데이터를 각도표시기로 작업자가 위치하는 곳에서 수신하여 볼 수 있도록 하는데 특징이 있다.In order to achieve this purpose, the angle measurement signal measured by the angle sensor unit of the angle measuring device installed in the ground, the tower or the top of the building to be measured vertically is transmitted to the position where the operator can see and the transmitted data is displayed on the angle indicator. It is characterized by receiving and viewing where the worker is located.

(송신기와 수신기의 거리는 100m가 적합하다.)The angle measuring device 1 is composed of an angle sensor unit 2, a sensor signal processing unit (MICOM) 3, and a data wireless transmitting unit 6, as shown in FIG. The angle sensor unit 2 of the measuring device 1 outputs an output voltage level (analog amount) differently according to the inclination of the sensor, and the sensor signal processing unit MICOM 3 outputs an analog-to-digital converter. By amplifying the analog signal and converting it into a digital signal, the data radio transmitter 6 transmits the digital signal to the receiver of the angle indicator (main body) 5 where the operator is located. (The distance between transmitter and receiver is 100m.)
각도표시기(5)는 데이터 무선수신부(6), 데이터 연산처리부(MICOM) (7), 데이터 표시부(Liquid-Crystal Display)(8)로 구성되어 있는데, 작업자가 위치하는 곳에 있는 각도표시기(5)의 데이터 무신수신부(6)에서는 각도측정기(1)의 데이터 무선송신부(4)에서 보내진 데이터를 수신하여 데이터 연산처리부(MICOM)(7)에 보내고 데이터 연산처리부(MICOM)(7)에서는 디-에이 컨버터 (Digital-Analog Converter)에 의하여 수신된 디지탈 신호를 아날로그 신호로 변환해서 데이터 표시부(LCD)(8)에 보내면 이 데이터를 작업자가 확인할 수 있도록 화면에 데이터 값을 표시한다.The angle indicator 5 is composed of a data radio receiver 6, a data operation processing unit (MICOM) 7, and a liquid-crystal display 8, and the angle indicator 5 is located at the operator's position. Data receiving unit 6 receives data sent from the data radio transmitter 4 of the angle measuring instrument 1 and sends the data to the data operation processing unit MICOM 7 and the data processing unit MICOM 7 receives the data. The digital signal received by the converter (Digital-Analog Converter) is converted into an analog signal and sent to the data display (LCD) 8 to display the data value on the screen for the operator to confirm.
또, 데이터 표시부(LCD)(8)에서는 전원을 넣을 때 화면에 안내메시지를 3초간 표시(회사로고, 사용법 등)하고 장치내부적으로 셀프테스트(SELF TEST)(DISPLAY부, 무선 데이타수신부 등)를 수행하며 각도센서부(2)에서 데이터 송신이 되지 않아 수신된 데이터가 없으면 부저음과 함께 신호가 없다는 안내메시지를 화면에서 표시한다. 한편, 셀프테스트에서 이상이 없으면 정상램프를 점등하고 각도센서부(2)에서 수신된 데이터가 설정된 최대값을 넘지 않으면 화면에 데이터로 표시한다. 수신된 데이터가 설정된 값을 넘으면 부저음과 함께 안내메시지를 화면에 표시한다.In addition, the data display (LCD) 8 displays a guidance message on the screen for three seconds when the power is turned on (company logo, usage, etc.), and executes a self test (SELF TEST) (display unit, wireless data receiver, etc.) inside the device. If the data is not transmitted from the angle sensor unit 2 and no data is received, a guide message indicating that there is no signal along with a buzzer sound is displayed on the screen. On the other hand, if there is no abnormality in the self-test, the normal lamp is turned on, and if the data received from the angle sensor unit 2 does not exceed the set maximum value, it is displayed as data on the screen. If the received data exceeds the set value, a guide message is displayed on the screen together with a buzzer sound.
