In addition, it also helps to realize the supervision and assessment of the material transportation and distribution process of each unit, which is conducive to further improving the efficiency of material distribution and the utilization rate of car skins, facilitating overall management, and realizing the reasonable and effective allocation of resources.

[0023] The present invention also provides a coal mine intelligent material distribution method, which specifically includes the following steps:

[0024] S1: Material claim and delivery;

[0025] The applicant fills in the application for the mine car and the delivered materials in the interactive interface of the logistics and distribution unit, fills in the relevant information of the use location, mine car type and material content when applying, and the logistics and distribution unit forms a material application form;

[0026] S2: Approval;

[0027] The management department approves the material requisition form issued by the logistics distribution unit. The logistics distribution unit combines the approved material requisition forms into a distribution material list, matches the loading information based on the distribution material list, and then sends the loading information to the mine car management unit;

[0028] S3: Generate loading information;

[0029] After receiving the loading information, the mine car management unit sends the mine car dispatching information to the mine car manager and sends the loading information to the loading personnel;

[0030] S4: loading and distribution;

[0031] After loading, the operator controls the mine car loaded with materials to drive to the destination for material delivery. When the mine car passes through the area covered by the RF antenna signal, the passive positioning base station device connected to the RF antenna will automatically read the tag information of the passive anti-metal electronic tag corresponding to the mine car, and locate and track the delivered mine car through the tag information;

[0032] At the same time, by setting up adjacent passive positioning base station devices to read the tag information of the same mine car, it is determined whether there is any missed detection of the vehicle information. When a passive positioning base station device located on the downstream side of the travel route detects the tag information of a mine car, and a passive positioning base station device located on the upstream side of the travel route does not detect the tag information of the mine car, it is determined that a missed detection occurs. When a missed detection occurs, the server controls the intrinsically safe motor action setting time through the motor controller, and drives the rack to move the guide rod away from the installation base plate by a set distance, so that the distance between the radio frequency antenna and the roadway is adjusted; if the missed detection still exists after the adjustment, the angle of the radio frequency antenna is further adjusted by manually adjusting the rotation angle of the rotating sleeve relative to the guide rod and the rotation angle of the rotating ferrule relative to the short shaft until the missed detection is eliminated;

[0033] S5: Confirmation of the minecart’s arrival at the destination;

[0034] After the mine car arrives at the destination, the passive anti-metal electronic tag on the mine car is read through the radio frequency antenna covering the destination and the passive positioning base station device connected to the radio frequency antenna. After confirming that it has arrived at the destination, the underground logistics distribution management module sends an arrival reminder to the corresponding explosion-proof mobile terminal through the underground logistics mobile terminal module to remind the unloading personnel to go to the underground parking lot in time to pull the car and confirm the mine car; after the unloading personnel arrive at the underground parking lot and confirm that they have arrived at the destination, they send a confirmation instruction to the underground logistics mobile terminal module through the explosion-proof mobile terminal, and perform unloading operations to complete the material distribution process;

[0035] S6: Return of the minecart;

[0036] After the material distribution is completed, the operator controls the mine car to drive to the return yard to return the mine car. The underground logistics distribution management module confirms whether the mine car has arrived at the return yard through the passive positioning base station equipment and radio frequency antenna installed near the yard, and sends a return reminder message to the explosion-proof mobile terminal of the yard personnel after arriving at the return yard. After the yard personnel confirm the return on site, they send a confirmation return instruction to the underground logistics mobile terminal module.

[0037] Furthermore, in order to improve the intelligence of material distribution, for material requisition forms with large material application quantities, the materials are split into multiple parts to form multiple distribution material lists, so that the materials can be loaded and distributed through multiple mining vehicles.

[0038] Furthermore, in order to facilitate the handover of usage rights, in S5, after the material distribution of the user unit is completed and the mine car has not yet been brought up to the well, when other user units want to use the mine car, the underground logistics mobile terminal module sends a mine car handover instruction to the underground logistics distribution management module through the explosion-proof mobile terminal, and the underground logistics distribution management module reviews the handover authority. After the review is passed, the management authority of the mine car is changed to other user units, and the underground logistics mobile terminal module sends a permission for the handover of usage rights to the explosion-proof mobile terminal of the requester.

[0039] This method can ensure the reasonable connection of various distribution links of underground materials, realize positioning and tracking in the whole process of logistics transportation, and effectively supervise the arrival and return process of material transport vehicles. It can effectively improve the distribution efficiency of materials and the utilization rate of mine vehicles, and facilitate the overall management and scheduling of resources.

[0070] like Figure 7 As shown, the present invention also provides a coal mine intelligent material distribution method, which specifically includes the following steps:

[0071] S1: Material claim and delivery;

[0072] The applicant fills in the application for the mine car and the delivered materials in the interactive interface of the logistics and distribution unit, fills in the relevant information of the use location, mine car type and material content when applying, and the logistics and distribution unit forms a material application form;

[0073] S2: Approval;

[0074] The management department approves the material requisition form issued by the logistics distribution unit. The logistics distribution unit combines the approved material requisition forms into a distribution material list, matches the loading information based on the distribution material list, and then sends the loading information to the mine car management unit;

[0075] S3: Generate loading information;

[0076] After receiving the loading information, the mine car management unit sends the mine car dispatching information to the mine car manager and sends the loading information to the loading personnel;

[0077] S4: loading and distribution;

[0078] After loading, the operator controls the mine car loaded with materials to drive to the destination for material delivery. When the mine car passes through the area covered by the RF antenna signal, the passive positioning base station device connected to the RF antenna will automatically read the tag information of the passive anti-metal electronic tag corresponding to the mine car, and locate and track the delivered mine car through the tag information;

[0079] At the same time, by setting up adjacent passive positioning base station devices to read the tag information of the same mine car, it is determined whether there is any missed detection of the vehicle information. When a passive positioning base station device located on the downstream side of the travel route detects the tag information of a mine car, and a passive positioning base station device located on the upstream side of the travel route does not detect the tag information of the mine car, it is determined that a missed detection occurs. When a missed detection occurs, the server controls the action setting time of the intrinsically safe motor 2-5 through the motor controller, and drives the rack 2-14 to move the guide rod 2-10 away from the mounting base plate 2-7 by a set distance, so that the distance between the radio frequency antenna and the lanes is adjusted; if there is still a missed detection after the adjustment, the angle of the radio frequency antenna is further adjusted by manually adjusting the rotation angle of the rotating sleeve 2-4 relative to the guide rod 2-10 and the rotation angle of the rotating sleeve 2-15 relative to the short shaft 2-11 until the missed detection is eliminated;

[0080] S5: Confirmation of the minecart’s arrival at the destination;

[0081] After the mine car arrives at the destination, the passive anti-metal electronic tag on the mine car is read through the radio frequency antenna covering the destination and the passive positioning base station device connected to the radio frequency antenna. After confirming that it has arrived at the destination, the underground logistics distribution management module sends an arrival reminder to the corresponding explosion-proof mobile terminal through the underground logistics mobile terminal module to remind the unloading personnel to go to the underground parking lot in time to pull the car and confirm the mine car; after the unloading personnel arrive at the underground parking lot and confirm that they have arrived at the destination, they send a confirmation instruction to the underground logistics mobile terminal module through the explosion-proof mobile terminal, and perform unloading operations to complete the material distribution process;

[0082] S6: Return of the minecart;

[0083] After the material distribution is completed, the operator controls the mine car to drive to the return yard to return the mine car. The underground logistics distribution management module confirms whether the mine car has arrived at the return yard through the passive positioning base station equipment and radio frequency antenna installed near the yard, and sends a return reminder message to the explosion-proof mobile terminal of the yard personnel after arriving at the return yard. After the yard personnel confirm the return on site, they send a confirmation return instruction to the underground logistics mobile terminal module.

[0084] In order to improve the intelligence of material distribution, for material requisition forms with large material application quantities, the materials are split into multiple parts to form multiple distribution material lists, so that they can be loaded and distributed through multiple mining cars.

[0085] In order to facilitate the handover of usage rights, in S5, after the material distribution of the user unit is completed and the mine car has not yet been brought up to the well, when other user units want to use the mine car, the underground logistics mobile terminal module sends a mine car handover instruction to the underground logistics distribution management module through the explosion-proof mobile terminal. The underground logistics distribution management module reviews the handover authority. After the review is passed, the management authority of the mine car is changed to other user units, and the underground logistics mobile terminal module sends a permission for the handover of usage rights to the explosion-proof mobile terminal of the requester.
