Description

An angle meter which is used wireless transmission-reception}

The present invention relates to an angle measuring device. 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.

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.

The present invention aims to solve such a problem, and the object of the present invention is to make it possible to conveniently check the measurement result in the place where the worker is located, without going to an angle measuring device installed in a place where the worker is inaccessible.

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.

This design is vertical to the angle measuring device when it is located in a place where the angle measuring device is inaccessible to the operator such as a high tower, an enclosed place or an underground facility in the construction where the verticality of civil engineering and building construction should be checked. When the angle measurement data measured by attaching the degree sensor, the sensor signal processing device, and the transmitter is transmitted, the angle measurement data signal transmitted to the operator in the work room, the control room, the driver's seat, or the like for the operator to carry and receive is calculated by the receiver. Processing is then performed to display the angle measured by the sensor in the data display unit.

This will be described with reference to the drawings.

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 4 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 wireless transmitter 4 transmits the digital signal to the receiver of the angle indicator (body) 5 where the operator is located. (The distance between transmitter and receiver is 100m.)

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. The data reception unit 6 receives data sent from the data radio transmitter 4 of the angle measuring device 1 and sends the data to the data operation processing unit MICOM 7 and receives the data received from the data operation processing unit MICOM 7. Is sent to the data display (LCD) 8, the data value is displayed on the screen so that the operator can confirm this data.

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 measuring device 1 and there is no data 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 measuring instrument 1 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.

Referring to the operation of the angle measuring device of the present invention by the circuit as follows.

The transmission circuit of the angle measuring device 1 is connected to an angle sensor unit U1 (2), a sensor signal processing unit (Microcomputer, MODEL No: 80C31 (intel)) (U2) (3), and a data radio transmitter (U3) (4). In the angle sensor unit U1 (2), a signal is output according to the measurement angle (maximum ± 45 °), and the output is calculated by the sensor signal processing unit (MICOM) U2 (3) and then the data wireless transmitter unit ( When the data is transmitted to the serial by U3) (4), the data wireless transmitter U3 (4) transmits the data at a predetermined frequency (operating frequency: 445.7 MHz, data transmission speed 2400 bps). The power supply unit U4 serves as a battery (9V) and a DC adapter (DC 5V).

The receiving circuit of the angle indicator 5 detects data from the data radio receiver U5 (6), which is wirelessly received, and transmits the data to the data computation processor MICOM U6 (7) by serial (SERIAl). The processing unit (MICOM) U6 (7) processes the data and sends it to the data display unit (LCD) U7 (8), and the data display unit (LCD) U7 (8) displays the sensor angle according to the input data. do.

The power supply unit U8 is a battery (9V) and a DC (DC) adapter (DC 5V).

If you need to measure the verticality by attaching an angle measuring instrument where it is difficult for the operator to access, you can view the measurement data with the angle indicator while in the situation room, control room, driver's seat, etc. In the field, the angle measuring device of the present invention can be conveniently used in underground water line wall construction and pile installation (CIP) construction or underground facilities (columns, etc.), construction facilities, drilling (for deep well excavation) construction, tower installation construction, etc. Can be.
