When the distance measuring instrument is used in large-scale projects, it will run out of power before a single day of measurement work is completed. The battery needs to be replaced frequently before the measurement work can be continued. Therefore, the existing distance measuring instruments have the problem of low battery life.

[0029] like Figure 1 , a multifunctional distance measuring device, comprising: a balance frame 1, a distance measuring wheel 2, a support rod 3, a digital display control panel 4, a handle 5 and a solar panel 6;

[0030] A pair of distance measuring wheels 2 are symmetrically mounted on the gimbal 1; the lower end of the support rod 3 is connected to the gimbal 1; the upper end of the support rod 3 is connected to the digital display control board 4; the handle 5 is connected to the digital display control board 4 and is located relatively rearward of the multifunctional distance measuring device; the solar panel 6 is mounted on the gimbal 1 and is located relatively forward of the multifunctional distance measuring device;

[0031] The solar cell panel 6 is electrically connected to the digital display control board 4 and the distance measuring wheel 2 respectively; the distance measuring wheel 2 is communicatively connected to the digital display control board 4 .

[0032] This solution provides a multifunctional distance measuring device, which has a pair of distance measuring wheels 2 installed on a balance frame 1. The device can store electricity through a solar panel 6 in a daytime environment and can continuously power the distance measuring wheels 2 and a digital display control panel 4. At the same time, it has the advantages of stable balance and long battery life, solving the problems of existing distance measuring devices using a single distance measuring wheel 2 that cannot be balanced, resulting in inaccurate distance measurement and high power consumption.

[0033] Specifically, this solution includes a pair of distance measuring wheels 2. Common knowledge indicates that the distance measuring wheels 2 are based on a proportional relationship between the circumference of the wheel and the circumference of the measuring wheel. As the distance measuring wheel 2 rolls, its circumference is physically or electronically recorded on its measuring scale. When the distance measuring wheel 2 rolls one circle, the pointer on the measuring scale moves one unit distance. The measuring wheels are communicatively connected to a digital display control board 4, allowing the digital display control board 4 to directly read the value on the measuring scale and, in turn, directly determine the distance rolled by the distance measuring wheel 2. This solution utilizes two types of distance measuring wheels 2, which can directly provide two readings to the digital display control board 4. This allows the two values ​​to be compared as needed to determine the measurement error between the left and right distance measuring wheels 2, thereby making the values ​​more referenceable and accurate. At the same time, this solution also includes a solar panel 6, which is electrically connected to the digital display control board 4 and the distance measuring wheel 2. On the one hand, using two distance measuring wheels 2 will result in high power consumption for distance measurement. The solar panel 6 can overcome the problem of high power consumption caused by using multiple distance measuring wheels 2. Under sunlight conditions, the solar panel 6 can convert solar energy into electricity and store it, which can continuously power the measuring meter of the distance measuring wheel 2 and the digital display control board 4. Especially during nighttime operation, after charging during the day, the solar panel 6 can power the distance measuring wheel 2 and the digital display control board 4 at night, avoiding the situation of power outage during nighttime operation. At the same time, the solar panel 6 of this solution is mounted on the gimbal 1. When the multifunctional distance measuring device is parked, the gimbal 1 can be tilted so that the lower part of the solar panel 6 touches the ground, forming a tripod structure, which can realize the parking function of the multifunctional distance measuring device. In this way, this solution combines the advantages of stable balance and long endurance, can fully utilize the advantages of solar energy as a power source, avoids the situation where the dual distance measuring wheels 2 consume too much power and need to frequently replace batteries, and solves the problem that the existing distance measuring device using a single distance measuring wheel 2 cannot be balanced, resulting in inaccurate distance measurement and high power consumption.

[0034] The communication connection method of this solution refers to the communication between connected devices through signal transmission interaction, which can be divided into wired connection and wireless connection; wired connection includes conventional data cable connection; wireless connection includes conventional WiFi, Bluetooth, infrared, NFC, etc.

[0043] The handle 5 of this embodiment is preferably designed to have a certain tilt angle. Specifically, the connecting arm 51 gradually tilts from the digital display control panel 4 to the gripping arm 52, so that the gripping arm 52 is offset from the middle of the digital display control panel 4. This allows the operator to freely hold the gripping arm 52 vertically when controlling it, without having to hold the arm in front of the body and keep it tilted for a long time, thereby reducing the labor intensity of distance measurement.

[0044] Optimally, the connecting arm 51 is positioned at the digital display control board 4 in an adjustable manner, so that the holding arm 52 is adjusted to be biased toward the relatively left side or relatively right side of the digital display control board 4 .

[0045] The connecting arm 51 of the present invention can be installed on the digital display control panel 4 by a known angle adjustment method, such as a rotation adjustment installation method, a disassembly and reinstallation installation method, or a movement adjustment installation method, etc., as long as the angle of the connecting arm 51 changes before and after installation, and when the connecting arm 51 is angle-adjustable, the connecting arm 51 can drive the holding arm 52 to shift in angle, so that the holding arm 52 is biased toward the relative left or relative right side of the digital display control panel 4, so as to switch to adapt to the dominant hand of the staff.

[0046] Optimally, it further includes: an angle adjustment seat 8;

[0047] The angle adjustment seat 8 is fixed to the upper end of the support rod 3 , and the bottom surface angle of the digital display control board 4 is adjustable on the angle adjustment seat 8 .

[0048] The digital display control board 4 of this solution can be directly or indirectly connected to the support rod 3; for the embodiment of indirect connection, this solution preferably uses an angle adjustment seat 8 to connect the digital display control board 4 and the support rod 3; the digital display control board 4 can be installed on the angle adjustment seat 8 in an angle-adjustable manner, and the inclination angle of the digital display control board 4 can be adjusted to avoid the direction of reflection during ranging, so as to prevent the light spot caused by reflection from affecting reading or control.

[0050] The support rod 3 of this embodiment is preferably a foldable structure that can be folded to different heights, so that the digital display control panel 4 and the handle 5 can be placed at a desired height, thereby flexibly switching to suit the height of the staff. Specifically, the support rod 3 can be a tube-in-tube structure, with the inner tube being telescopic and constrained within the outer tube, thereby achieving telescopic and foldable height.

[0051] Optimally, the digital display control panel 4 is provided with a digital display screen 41 and control buttons 42 .

[0055] Optimally, the solar cell panel 6 is a folding structure.

[0056] The solar panel 6 of this embodiment preferably has a folding structure that can be deployed in a direction other than the distance measuring wheel 2. For example, the solar panel 6 can be deployed relatively forward of the multifunctional distance measuring device. This exposes more semiconductor material during deployment, increasing the area exposed to sunlight and improving the power storage capacity, thereby increasing the endurance of the distance measuring device under the same solar exposure time. During operation of the multifunctional distance measuring device, the solar panel 6 can be folded to prevent it from interfering with detection.
