Description

TECHNICAL FIELD

[0001] The utility model discloses a luminance adjustable light-emitting prism target board belongs to prism auxiliary tool technical field. BACKGROUND

[0002] The prism is a transparent polyhedron surrounded by two two intersecting planes, but the planes are not parallel to each other, the side is the plane of light incidence and emission, and the plane perpendicular to the side is called the main section. According to the shape of the main section, it is generally divided into three prisms, right-angle prisms and five-angle prisms.

[0003] When measuring the high-precision deformation monitoring network, the method of total station corner network is often used. In order to minimize the influence of shading difference and weather changes and other adverse factors, the observation work is usually arranged at night. Especially in the total station measurement in the tunnel and other total station observation projects at night, the operating personnel often need to use a searchlight to assist the total station in aiming at the prism for observation. However, this approach will cause the side shading phenomenon of the searchlight, which not only affects the accuracy of the measurement, but also reduces the efficiency of the operation.

[0004] In the prior art, in order to reduce the adverse effects of the searchlight on the measurement, improvements have been made to the prism light and the target board light. However, the prism light improvement only realizes the light-emitting function of the prism body. For the current advanced measurement robots, they can realize automatic aiming and automatic observation after learning and recognizing the prism target. This process does not require additional lighting. However, in the manual observation process, in order to accurately read the horizontal angle and the vertical angle, the horizontal and vertical triangular symbols on the target board still need to be aimed at. In this case, the light-emitting of the prism body does not substantially help the aiming of the target board. On the other hand, the target board light improvement is usually achieved by adding lighting devices to the target board, and the lighting light is directed towards the observation instrument. In actual application, these lighting devices not only illuminate the target board, but also bring strong interference to the aiming work of the measurer, making the aiming difficult. SUMMARY

[0005] The utility model overcomes the insufficient prior art, proposes a kind of luminance adjustable light-emitting prism target board, including target board, prism frame, light-emitting device, luminance adjusting device and power device;

[0006] The mounting hole is arranged on the target board, and the mounting hole is used to set the prism frame, and the first surface of the target board is provided with a geometric pattern for aiming;

[0007] The light-emitting device is arranged on the outer frame of the target board, and is used to provide illumination to the target board.

[0008] The luminance adjusting device and the power supply device are arranged on the second surface of the sighting telescope and are connected with the light emitting device.

[0009] Preferably, the light emitting device is specifically optical fiber or LED lamp strip.

[0010] Preferably, the geometric pattern is symmetrically arranged on the sighting telescope.

[0011] The extension line of the middle line of the geometric pattern passes through the orthographic projection point of the center point of the prism frame.

[0012] Preferably, the geometric pattern is provided with a reflective layer.

[0013] Preferably, the light emitting device is adjustable in light color temperature.

[0014] Preferably, the luminance adjusting device is a knob switch for controlling the luminance and on-off of the light emitting device.

[0015] Preferably, the outer frame is protruded from one side of the first surface.

[0016] The outer frame of the sighting telescope is integrally formed with the sighting telescope.

[0017] Preferably, the width of the outer frame of the sighting telescope is 5-10 mm.

[0018] Preferably, the outer frame of the sighting telescope is plastic-sealed by high-transparency plastic or glue.

[0019] Preferably, the power supply device is a rechargeable battery.

[0020] Compared with the prior art, the sighting telescope of the utility model has the advantages that the sighting telescope of the utility model is provided with the light emitting device arranged on the outer frame, so that the measuring work can be normally performed at night or in an area with insufficient light, and the measuring efficiency is improved. The luminance adjusting device is used to adjust the luminance of the light emitting device, so that the strong light is prevented from interfering with the sighting of the user. The sighting telescope has simple principle, high operability and low production cost, and has strong universality, so that the sighting telescope can be upgraded and modified on the basis of the existing sighting telescope.
