Problems solved by technology

However, due to the use of the SLAM algorithm, it is first necessary to scan and collect environmental data first, and then combine the SLAM algorithm for fine positioning, the operation is complex, and at the same time matching with the overall indoor environmental data requires a large number of iterative operations, and the time complexity of the algorithm is high. This is not conducive to the real-time positioning of the robot
At the same time, the SLAM algorithm itself has accumulated errors in the data matching process, which reduces the positioning accuracy and navigation accuracy.
[0005] To sum up, it can be seen that the commonly used positioning methods at this stage cannot meet the requirements of building automation and intelligence due to reasons such as complexity and accuracy.

Embodiment 1

[0096] Suppose a room is 4 meters long from north to south and 3 meters wide from east to west. Where are smart devices located? Figure 7 The measurement points shown. The first posture faces east (E), measures the distance b=2 from the wall, rotates 60 degrees toward the wall, and measures the distance c=2 from the wall. Obtain the distance between the two measurements on the wall, denoted as a. According to the law of cosines,

[0097]

[0098] Calculate the distance between the robot's current position and the wall, denoted as d. Calculated to get:

[0099]

[0100] Therefore, the distance between the current positioning device and the east wall is rice.

[0101] When the positioning device rotates to the south, then measure the distance m=2 meters from the wall, rotate 60 degrees toward the wall, and measure the distance n=2 from the wall. Calculated in the same way as Therefore, the distance between the current positioning device and the south wall is ri...

Abstract

The invention discloses an intelligent device for indoor positioning in a construction site and a control method thereof. The intelligent device comprises a connecting part for mounting the intelligent device on a construction robot body and a laser positioning and ranging part arranged at the lower end of the connecting part for mounting a laser transmitting and receiving device, wherein the connecting part and the laser positioning and ranging part are connected through a horizontal rotating mechanism; the connecting part is internally provided with a control center for controlling the laserpositioning and ranging part and the horizontal rotating mechanism to work; and the laser positioning and ranging part is provided with a pointing device for indicating and positioning the horizontaldirection of the intelligent device. In comparison with the existing positioning method, more accurate construction site indoor positioning can be provided; the laser ranging device is used for positioning without deploying additional sites, and the deployment is simple and convenient; and the device disclosed in the invention can be mounted on a construction robot and work together with the robot, and the automatic level and the intelligent level are high.

Description

technical field [0001] The invention relates to the technical field of mechanical construction, in particular to an intelligent device for indoor positioning on a construction site, and also relates to a control method for the intelligent device. Background technique [0002] In recent years, the aging of workers on construction sites in my country has become more and more serious. The aging of workers has restricted the development of the construction industry, and the biggest problem for aging construction workers is safety. With the advancement of science and technology and the development of the construction industry, construction automation and intelligence are an inevitable trend. Therefore, construction robots stationed in construction sites to carry out precise, accurate and efficient construction is an important direction for construction intelligence. At the same time, the construction automation of construction robots requires the support of high-precision positio...
