Example Embodiment

[0028] Example 1

[0029] like figure 1 As shown, this embodiment discloses a precise positioning system for downhole personnel, including a card end, a positioning card reader, a processor and a downhole vehicle. Wherein, the card end is a wireless communication card, and the card end records the identification of the personal information of the card holder. In this embodiment, the card end is a radio frequency card, and the positioning card reader is a radio frequency card reader. In other embodiments, the card end and the positioning card reader may also adopt UWB positioning technology or other equivalent devices of indoor positioning technology, which belong to the prior art and can be directly applied, and will not be repeated here.

[0030] There are multiple positioning card readers, which are respectively arranged along the length direction of the underground tunnel according to the preset interval distance. In this embodiment, one positioning card reader is provid...

Example Embodiment

[0037] Embodiment 2

[0038] Different from the first embodiment, in this embodiment, the processor is also used to store the distance correction coefficient between each positioning card reader, and is also used to perform correction analysis according to the distance correction coefficient; The correction coefficient between the card readers is continuously greater than the first preset value, and the duration is greater than the preset duration, or the correction coefficient between two adjacent positioning card readers is greater than the second preset value, then the processor Generate alarm information; wherein, the second preset value is greater than the first preset value, and the content of the alarm information includes the type of abnormality. The specific values ​​of the first and preset values ​​and the second preset value can be specifically set by those skilled in the art according to the daily interference situation of the underground roadway and the actual req...

Example Embodiment

[0040] Embodiment 3

[0041] Different from the second embodiment, in this embodiment, the processor is further configured to mark two adjacent positioning card readers corresponding to the alarm information when there is alarm information, and mark the two adjacent positioning card readers corresponding to the alarm information, and mark the two adjacent location card readers corresponding to the alarm information. When there is a space between two adjacent positioning card readers, according to the real-time detection distance of the underground vehicle sent by the two adjacent positioning card readers, the position analysis of the interference source is performed. The processor is further configured to generate suggested processing area information according to the analysis result of the position of the interference source.

[0042] After the alarm information is generated, the processor in the present application also automatically analyzes the location of the interference...

Abstract

The invention relates to the technical field of underground intelligent management, in particular to an underground personnel accurate positioning system which comprises a card end, a positioning card reader and a processor. The card end is a wireless communication card, and an identifier of personal information of a person holding the card is recorded in the card end; the plurality of positioning card readers are respectively arranged along the length direction of an underground roadway according to a preset spacing distance; the positioning card reader is used for reading information of a card end in a coverage range, measuring the distance between the positioning card reader and the card end, and sending personal information of the card end and the corresponding distance to the processor; the position information of each positioning card reader is stored in the processor, and the processor is used for performing positioning analysis according to the position information of each positioning card reader, the distance sent by each positioning card reader and the corresponding personal information to obtain the basic positioning of the underground personnel. By using the system, the personnel entering the underground roadway can be accurately positioned even in the presence of environmental interference.

Description

technical field [0001] The invention relates to the technical field of underground intelligent management, in particular to a precise positioning system for underground personnel. Background technique [0002] With the development of intelligent management, the application scenarios of intelligent management are becoming more and more extensive, and the underground management of mines has gradually become intelligent. The intelligent management of the underground mainly refers to the centralized monitoring and management after collecting various status data of the underground roadway, so as to manage the underground roadway in a visual centralized management method. [0003] Among them, in order to effectively manage the underground personnel, it is necessary to precisely locate the underground personnel. Since the underground tunnel is usually a long and narrow straight channel, the current mainstream positioning method is usually UWB positioning technology, that is, a pos...
