Problems solved by technology

[0004] But this brings new problems. For example, for a passenger car, the positioning of the car itself is no problem, but when a person is on the car, it is subject to the influence of the metal car body on the electromagnetic wave (leading to ranging deviation, ranging failure, etc.) ), the car runs at a fast speed (0.5Hz cannot support this speed well), and the people in the car are crowded and blocked from each other, which lead to deviations and failures in the UWB positioning of the human tag itself

Embodiment Construction

[0031] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.

[0032] combine figure 1 , the present invention proposes a positioning compensation method suitable for different objects in a coal mine area, each of which is provided with a positioning tag with an independent number in one-to-one correspondence.

[0033] The positioning compensation method includes:

[0034] Determine whether there is a following relationship between two objects of different types in real time. If there is a following relationship between any two objects of different types, and the absolute value of the positioning frequency difference between the two is greater than the set frequency threshold, the positioning frequency will be lower. The object is set as the compensated object, the object with high positioning frequency is set as the compensation object, and the positioning p...

Abstract

The invention discloses a positioning compensation method suitable for different objects in a coal mine area. If the absolute value of the positioning frequency difference of the target is greater than the set frequency threshold, the object with a lower positioning frequency is set as the compensated object, and the object with a higher positioning frequency is set as the compensation object. Combined with the positioning point information of the compensation object, according to the set Compensate the anchor point of the compensated object according to the specified compensation rules. The present invention can use the positioning point information of objects with high positioning frequency to compensate the positioning points of objects with low positioning frequency, reduce the positioning interference between the two and ensure the positioning of the two without increasing the system capacity burden Accuracy: use different compensation schemes for objects in different scenarios, or further reduce the system capacity burden, or save the relative displacement information of both parties in the following relationship as much as possible.

Description

technical field [0001] The invention relates to the technical field of coal mine area positioning, in particular to a positioning compensation method suitable for different objects in the coal mine area. Background technique [0002] Existing positioning schemes can support two conventional positioning objects under coal mine tunnels—people and vehicles. The vehicles here include conventional coal trucks and people trucks. [0003] In order to ensure the capacity of the system, for human tags, the positioning frequency is relatively small (for example, 0.5 Hz). Due to the limited walking speed of human beings, the small positioning frequency is also sufficient to ensure sufficient sampling when they are moving. For the car label, due to its high speed, if it is still positioned at a low frequency (such as 0.5Hz), it will cause a large difference in position between the two positionings, which will bring inconvenience to the display effect and data processing (such as filteri...
