Detailed Description
In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following description is further provided with reference to the specific embodiments and the accompanying drawings.
As shown in fig. 1, the main body of the automatic measuring device for laser sensing angle range is a platform (also called a base or a pedestal) made of metal, and a fixing module, a laser emitting module (a laser head facing the fixing module), a display control module and a printing module are fixedly installed on the platform from left to right. The fixed module is actually a rotating mechanism that can rotate horizontally or in pitch by a fixed angle under the control of a servo motor. The end part of the fixed module is provided with a laser sensing assembly, and the laser sensing assembly synchronously rotates along with the fixed module when the fixed module rotates. The laser sensing component is mainly used for receiving and detecting laser signals emitted by the laser emitting module. The display control module mainly plays a role in controlling each electrical element and processing and displaying received data, and can select a microprocessor or a single chip microcomputer with a display screen. The printing module is mainly used for printing test results and the like, and can select a thermal printer commonly used for cashing. Thereby fixed module, laser perception subassembly, laser emission module, print module link to each other through cable and display control module and realize communication and data exchange, and external power source or hide the battery in the platform and supply power for whole equipment.
The laser sensing angleThe use method of the automatic range measuring device is shown in fig. 2. The method comprises the steps of firstly, initializing after starting up to confirm that equipment is normal, and then testing numbered laser sensing assemblies to be tested in sequence. After a certain laser perception subassembly that awaits measuring is installed on fixed module, laser emission module transmission laser signal (20Hz) under the instruction of display control module, laser perception subassembly receives laser signal, and display control module calculates detection probability P, the computational formula according to the laser number of times of transmission and the laser number of times of receipt: number of times of receiving laser light/number of times of emitting laser light × 100%. If P is larger than 90%, the fixed module and the laser sensing component to be detected do not need to rotate, and the current initial azimuth angle A is directly recorded1. If P is less than 90%, the whole fixed module and the laser sensing component to be detected horizontally rotate by 0.3 degrees, then the detection probability P is measured again and calculated until the detection probability P is greater than 90% for the first time1. When determining the azimuth angle A1Then, the display control module instructs the fixing module and the laser sensing assembly to be tested to integrally horizontally rotate for 35 degrees, and then the steps are repeated, so that the final azimuth angle A is determined2。
Determining good initial and final azimuth angles A1、A2Then, the display control module instructs the fixed module and the laser sensing component to be detected to integrally rotate 90 degrees laterally, then the detection probability P is measured and calculated until the detection probability P is greater than 90 percent for the first time, and the current pitch angle B is recorded1。B1After the determination, the display control module instructs the fixed module and the laser sensing assembly to be tested to integrally and horizontally rotate by 85 degrees, and the steps are repeated, so that the final pitch angle B is determined2. The final measured laser perception angle is as follows: azimuth angle: a. the2-A1Angle of pitch B2-B1. The result can be printed out through the printing module and pasted on the equipment to be tested.
The device greatly improves the measurement efficiency and stability, and has good effect in practical application.
