DQL-Z1 Intelligent Theodolite Compass Instruction Manual

DQL-Z1 Intelligent Theodolite Compass

I. Application Areas

The Intelligent Theodolite Compass is a multifunctional, digital measuring instrument that integrates optics, mechanics, and electronics. It can measure azimuth, elevation angle, slant distance, horizontal distance, and elevation difference. Measurement data can be stored, viewed, and transmitted. The instrument is compact, lightweight, feature-rich, highly accurate, and easy to operate. It is suitable for applications such as forestry, agricultural land management, water conservancy projects, and national land surveys.

II. Product Structure

The instrument’s main structure comprises several components, including the distance-measuring head, vertical rotation mechanism, main-board housing, horizontal rotation mechanism, tubular compass, touch screen, and leveling mechanism, as shown in the figure below:

III. Functional Features

3.1 The measurement functions include: azimuth, elevation angle, slant range, horizontal distance, and elevation difference.

3.2 Magnetic Declination Setting: Corrects the deviation between “magnetic north” and “true north.”

3.3 Combining coarse aiming with optical sighting makes it easier to lock onto the target.

3.4 Pulse laser ranging offers rapid and accurate response.

3.5 Supports settings for magnetic declination, plot name, real-time time, and screen brightness.

3.6 The entire instrument features a single measurement key and is equipped with a color touchscreen, making operation simple.

3.7 Supports the storage, viewing, and transmission of measurement data, with a maximum capacity of 3 data sets, each containing 504 data points.

3.8 Supports both Bluetooth and USB external communication interfaces, with customizable transmission protocols.

IV. Technical Parameters

V. Quick Usage

5.1 Mount the instrument on a tripod and level it.

5.2 Press and hold the power button to turn on the device.

5.3 Enter the azimuth calibration page, slowly rotate the instrument, and when the tubular compass is centered, tap the “Calibrate” button on the screen to calibrate the azimuth.

5.4 Enter the sample plot measurement page. The azimuth and elevation angles are measured in real time. Aim the telescope at the target object, and press the measurement button to obtain the slant distance, horizontal distance, and height.

5.5 The “hold,” “store,” “view,” and “send” functions for measurement results can be performed using the on-screen buttons.

VI. Operating Procedures

6.1 Installation

6.1.1 Mount the instrument on the supplied tripod using the leveling mechanism at the base of the instrument, ensuring that the entire instrument is rotated during installation to fully tighten the threaded fasteners.

6.1.2 Hold the main housing shell and gently pry it while observing the circular bubble on the shell until the bubble is centered, indicating that the level adjustment is complete.

6.1.3 Press and hold the button on the right side of the display hinge, then tilt the display downward to the desired angle.

6.2 Power On and Off

Press and hold the “Power” button for about 2 seconds to turn the device on or off. After powering on, the screen will display the main menu.

6.3 Azimuth Calibration

First, loosen the locking screw at the top of the compass; then loosen the horizontal locking screw at the bottom of the main housing. Slowly rotate the instrument, and once the needle of the tubular compass is centered, tap the “Calibrate” button on the screen to complete the azimuth calibration.

Note: Minor deviations may occur when reading the pointer due to visual parallax.

6.4 Plot Measurement

6.4.1 Sample plot

Access the plot selection page via “Plot Measurement” in the main menu, then select a saved plot to enter the measurement page. To modify the plot name, tap the plot name on the current page, enter the new name on the pop-up keyboard screen (supporting up to 16 alphanumeric characters or 8 Chinese characters), and then tap Save.

6.4.2 Measurement

Laser-assisted aiming (optional): The distance-measuring head is equipped with a laser indicator at its base; pressing the button on the rear of the indicator toggles the laser on or off. This laser indicator is intended solely as a coarse aiming aid and may exhibit some deviation due to environmental changes. In addition, the laser is powered by a separate battery; to prolong battery life, be sure to turn off the laser immediately after use. This feature is available as an optional add-on.

Perimeter measurement: Click the “Perimeter” button, then use the “+” and “–” buttons below to select the current measurement direction. Slowly rotate the instrument while observing the azimuth reading; when the azimuth reaches the desired angle, tighten the horizontal locking screw. Next, tilt the upper distance-measuring head of the instrument up and down to aim at the target, and press the “Measure” button to complete the measurements of slant range and horizontal range.

Sample tree measurement: Click the “Sample Tree” button, then use the “+” and “–” buttons below to select the tree number you wish to measure. The “Sample Tree” button allows you to adjust the step size for changing the tree number in increments of 1, 5, or 10. Alternatively, you can click directly on the tree number and enter it in the pop-up dialog box. To measure distance, aim the instrument’s rangefinding head at the target and press the “Measure” button. To measure tree height, click the “Height Measurement” button on the screen. Following the on-screen prompts, first aim at a spot on the tree’s midsection with good reflectivity and press “Measure.” After the slant range and horizontal range data are displayed, aim at the base of the tree and press “Measure” again. Finally, aim at the top of the tree and press “Measure” one last time to obtain the tree’s height.

On the measurement page, tap the “Hold” button to either hold or refresh the perimeter or sample-tree data. In “Hold” mode, the data is locked and does not change; the “Save” and “Send” buttons become enabled, allowing you to save the current data locally or send it via Bluetooth. To send data via Bluetooth, you must first install Bluetooth debugging software or the corresponding professional software on the mobile device. Once the local device and the mobile device are successfully connected via Bluetooth, the data can be transmitted (see Section 6.7).

6.5 Data Viewing

Access the data viewing page through the main menu. The first page displays the plot name, maximum storage capacity, current storage capacity, the timestamp of the most recent record, and perimeter data. Clicking “Next Page” sequentially displays individual tree data.

Click the “Clear” button to erase all data for the current plot. Click the “Send” button to transmit the currently saved historical data from the plot to the computer via USB. To enable data transmission, first install the serial-port driver software (CH341) on the computer, then install a serial-port debugging tool or other specialized software. Connect the instrument to the computer using a data cable, launch the software on the computer, configure the serial-port settings (115200, 8, N, 1), and open the serial port. On the instrument’s “Data View” screen, click the “Send” button to transmit the current plot’s historical data to the computer.

6.6 Settings

On the Settings page, tap the text box, enter the desired magnetic declination, and then tap the “Set” button; after modifying the real-time time, tap the “Set” button again; and drag the brightness slider to adjust the screen brightness.

6.7 Bluetooth
