[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, but it is not a limitation to the present invention.

[0023] As Figure 1 shown, as an embodiment of the present invention, an infrared scanning cross-section measuring instrument includes:

[0024] A transmitting component, which includes a measuring instrument housing 1, an infrared transmitter, and a power supply device. Among them, two infrared emission ports are provided on the outer edge surface of the measuring instrument housing 1. The infrared emission ports are connected and fixedly installed with a rotating device inside the measuring instrument housing 1 for rotating the infrared emission ports. The infrared transmitter is fixedly installed on the outer edge surface of the rotating device, and one end of it far from the connection with the rotating device penetrates through the infrared emission port for cross-section measurement of the roadway 3. The power supply device is fixedly installed inside the measuring instrument housing 1 and is connected to the infrared transmitter for supplying power to the infrared transmitter.

[0025] A measuring component, which includes a main control chip, a distance measuring sensor, and an angle sensor. The main control chip is fixedly installed inside the measuring instrument housing 1. The distance measuring sensor is fixedly installed on the outer edge surface of the measuring instrument housing 1. The angle sensor is fixedly installed on the outer edge surface of the rotating device. Among them, the main control chip is connected to the distance measuring sensor for measuring the distance emitted by the infrared transmitter, and the main control chip is connected to the angle sensor for measuring the rotation angle of the rotating device.

[0026] In an embodiment of the present invention, there are two infrared emission ports on the measuring instrument housing 1 at a certain angle. For example, the two infrared emission ports form an included angle of 1°. The smaller the included angle, the closer the distances between the two infrared emission ports and the wall of the roadway 3 are. That is, the formed included angle shape is a triangle, and the two waist lengths of the triangle are closer to being equal, and the measurement error is smaller. The two infrared emission ports rotate simultaneously driven by a rotating device, and the angle of each rotation is equal to the included angle between the two infrared rays 2.

[0027] In an embodiment of the present invention, the present invention further includes a display component. The display component includes a display and a display module connected to the display. Among them, the display module is connected to the main control chip to visualize the data information measured by the distance measuring sensor and the angle sensor. Through the provided transmitting component and measuring component, the measurement requirements of operators for different-shaped cross-sections and for the cross-sectional areas of regular or irregular roadways are met, further solving the problems in the prior art. At the same time, through the provided display component, the data measured by the present invention is calculated, analyzed, and visually displayed, greatly improving the cost performance of the present invention.

[0028] In an embodiment of the present invention, the two infrared emission ports rotate synchronously with the infrared emitter to form multiple included angles on the roadway 3 surface. Among them, baffles are provided on both of the two infrared emission ports, and the baffles are slidably connected to the two infrared emission ports. When the user is performing distance measurement, one of the two infrared emission ports is closed by the baffle for measurement. At the same time, it is defined that the triangle formed by the two infrared rays 2 with a smaller included angle and the wall of the roadway 3 is an isosceles triangle. By using the distance measurement function of the infrared ray 2, the waist length of the isosceles triangle can be known. When the two infrared rays 2 rotate 180°, there will be N isosceles triangles with known included angles and known waist lengths. The sum of the areas of the N isosceles triangles is the cross-sectional area of the roadway 3.

[0029] In an embodiment of the present invention, the model of the main control chip is AT87C552, the model of the distance measuring sensor is USO10TR-40MP, and the model of the angle sensor is HAL3727.
