UWB wireless module among the hydraulic support controlling means is equivalent to the UWB basic station to all UWB basic stations are all independently numbered. The personnel positioning function is realized through real-time communication between the UWB base station and the UWB tag and through a specific algorithm (TDOA algorithm), namely the position of a worker relative to the action support is determined, when personnel appear in a dangerous area near the action support, the support control device is immediately locked to stop action, and the audible and visual alarm starts to give an alarm to prompt the personnel to get away from the dangerous area.
When the UWB is generally applied to realize a plane positioning function, more than three UWB base stations are required to be fixed in position to determine the coordinates of each base station, and then the coordinates of a mobile tag are obtained through an algorithm to determine the position of the tag. The UWB base station of the support control device related by the invention continuously moves along with the advancing of the coal mining machine, and the staff needing to be positioned also moves, thereby bringing certain difficulty to the positioning of the staff. However, the hydraulic supports of the working face are the same, and the hydraulic supports are parallel before or after the hydraulic supports are moved, so that the relative coordinate positions of the base stations on the adjacent three support control devices can be determined and the dangerous area can be calculated only by installing the support control devices at the central positions of the hydraulic supports relative to the width.
The working principle of the control system is as follows: supposing that the width of the hydraulic support is D and the length of the hydraulic support is L, the vertical distance from the UWB base station on the support control device to the front end of the hydraulic supportIs separated to L1The push-out (or retraction) length of the push cylinder is L2And the width of the scraper conveyor is W. Thus, when the motion support is the first support, as shown in fig. 13, the base station 1 is used as the origin of the plane coordinate system, i.e., G1(0,0) to give G2(D,0),G3(2D,0), four vertex coordinates of the danger area S are
Wherein the pushing length of the pushing cylinder is L2The other constants are obtained by measuring with a built-in travel sensor, and relevant parameters are configured into the bracket control device through a human-computer interface according to the actual situation on site. In addition, the UWB tag is worn in a helmet of each worker. Before or during the action of the hydraulic support, the UWB base station of the support control device temporarily networks the other two adjacent base stations, negotiates the action support as a main base station, then applies a TDOA algorithm to always judge the position of a nearby UWB tag, and when the system judges that a worker enters a dangerous area (namely the horizontal coordinate of the position of the UWB tag is in the position of a dangerous area)
To
And the ordinate is at- (L-L)1) To L1+L2+ W), the action bracket will immediately block stopping the action of the hydraulic bracket and the audible and visual alarm will start to alarm to warn the staff to immediately leave the dangerous area.
When the action support is a certain support in the middle of the working surface, as shown in fig. 14, taking the hydraulic supports 1, 2 and 3 as examples, the action support is the 2 nd support, and at this time, the action support 2 negotiates as a main base station and is defined as a plane coordinate system origin, and then the position of a nearby UWB tag is always judged by applying a TDOA algorithm with the left and right adjacent support networks. At this time G2(0,0),G1(-D,L2),G3(D, 0). The coordinates of the four vertices of the danger area S are unchanged.Similarly, when the action support is the last support, the action support serves as a main base station and is defined as a plane coordinate system origin, and then the position of a nearby UWB tag is always judged by applying the TDOA algorithm with two adjacent support networks, as shown in fig. 15.
Nothing in this specification is said to apply to the prior art.
It should be emphasized that the embodiments described in this specification are illustrative rather than restrictive, and thus the present invention includes, but is not limited to, the embodiments described in the detailed description, and all other embodiments that can be derived by those skilled in the art according to the technical solutions of the present invention, for example, the UWB wireless technology can also be a wireless technology such as WiFi, bluetooth, Zigbee, etc.; the automatic networking of a single adjacent three base stations can be automatic networking of more than three base stations; the TDOA algorithm may also be TOA or RSS algorithm, and the like, and the method also belongs to the protection scope of the present invention.
