Abstract

The calibration equipment and positioning device, equipped with 2-way communication radio components, will be installed on the ground and the ceiling of the field respectively. The calibration equipment will evaluate the score of signal quality by the strength, angle and the stability of signal generated by the positioning device. If the score is too low, the positioning device will be moved and reinstalled, then run the evaluation again. Once the score reaches the threshold, the coordinate of this positioning device will be measured by the level and rangefinder built on the calibration equipment.

Description

Positioning system for correcting and optimizing positioning effect

The present invention relates to a positioning system, and more particularly to a positioning system for correcting and optimizing positioning effects.

Most of the installation and correction mechanisms of the current indoor positioning equipment are used as the basis for adjusting the positioning equipment by the advantages and disadvantages of the actual positioning results. For example, when the accuracy of the field A is insufficient, the positioning device is added to enhance the accuracy; when the positioning of the field B is shifted to the left, the entire positioning device is moved to correct the offset situation. This type of correction mechanism is not only time consuming, labor intensive, but also more susceptible to damage to existing environments.

In addition, the current common correction processing method is to set the approximate position and then set it on the map through visual inspection. This will greatly affect the operation of the positioning system. Although a few operators use the mobile device to assist in detecting the signal strength, This is the basis for adjusting the positioning equipment. However, it is the experience of the engineer to judge what is the appropriate strength and weakness. Even if some manufacturers use the distance measuring instrument for coordinate setting, there are many problems, such as a lot of steps and the positioning equipment is not easy to use, for example: correction The equipment needs to be equipped with a laser range finder. The level is used to measure the height and plane position of the positioning equipment. Then, the radio frequency component for calibration is replaced to detect the strength, angle and stability of the wireless signal, and the signal quality score is defined. Quickly perform all-round detection and measurement of a single positioning device.

However, the mounting coordinates of the positioning device are the most important factors affecting the accuracy of the subsequent positioning. If the coordinates of the positioning device itself are set incorrectly, there will be errors in the object coordinates obtained by tracking and positioning. Therefore, it is necessary to provide a positioning system capable of effectively reducing labor waste, reducing correction error values, for correcting, and having an optimized positioning effect.

The range finder 123, the three-axis level 124, and the radio frequency component 125. Wherein, the positioning device 11 is disposed relatively above the field in a field (for example, the ceiling of the field), and the correction device 12 is disposed relatively below the same field (for example, the ground of the field); the vertical of the correction device 12 The laser range finder 122, the two horizontal laser range finder 123, the three-axis level meter 124, and the radio frequency component 125 are disposed on the distal direction 1211 of the stand 121; the control device 13 is disposed at the proximal end of the stand 121 In the direction 1212, the wireless range component 122, 123, and the three-axis level 124 are connected by wireless signals to the radio frequency component 125.

In one embodiment, control device 13 is a notebook computer. In another embodiment, the positioning device 11 includes a radio frequency component. In other embodiments, the radio frequency component selected by the positioning device 11 and the calibration device 12 is a high precision radio frequency component. In the embodiment of the present application, the positioning device 11 is configured to transmit a wireless signal; the calibration device 12 is used to verify and measure the wireless signal and coordinates of the bit device 11: the vertical laser range finder 122 is used for detecting the positioning.

The positioning system of the present application has the function of correcting and optimizing positioning, and adopts suitable high-precision wireless RF components, and integrates the existing calibration instruments such as laser range finder and level into a single calibration device, thereby utilizing integrated positioning correction. The device can shorten the detection and position measurement time of a single positioning instrument by half, effectively reducing the waste of labor and reducing the correction error value.

At present, the existing positioning correction method in the industry is divided into the following two steps:

Step 1. Use the positioning device calibration instrument to mount on the height-adjustable tripod, connect the notebook computer, connect the calibration instrument after the network setting, and use the positioning correction software to connect the calibration instrument to perform the positioning device calibration. The single positioning device needs to be obtained. The correction data of two or more orientations may be selected in two orientations of 0, 90, 180, and 270 degrees. The orientation data is calculated by the calibration software to obtain a trust value, to ensure whether the quality of the correction is met.

Step 2: Using a laser range finder to measure the drip height after the positioning device is installed, and then select the distance between the two fixed point measuring devices and the fixed point. After inputting the system, the relative position of the measuring device in the environment is calculated by the system.

The positioning system of the present application combines the above two steps into one. On a tripod with adjustable height and level, a vertical and two horizontal laser range finder is set up, and the value is received and filled into the soft body. The positioning device calibration instrument is installed above and connected to the computer to receive various information and store it at one time, eliminating the need to replace the device and the measurement parameters into the system.

The instrument performs signal correction and obtains the trust value. After confirming that the trust value meets the requirements, the positioning device signal confirmation is completed. If the trust value does not meet the demand, the position of the upper positioning device 11 is replaced and the measurement is performed again. After the positioning device signal confirmation is completed, the vertical laser range finder 122 is used to measure the height of the positioning device 11, and the horizontal laser range finder 123 is used to align the positioning points in the environment to measure the distance, and the relative position of the positioning device 11 in the space is confirmed. Complete the calibration procedure.
