Description

Technical Field

[0001] The invention belongs to the technical field of electronic control, and in particular relates to an intelligent ore discharge control system for an underground mine unloading station. Background Art

[0002] With the continuous development and change of science and technology and the continuous advancement of smart mine construction, intelligent control systems have been widely used in the mining industry. Intelligent control systems in underground mines are gradually replacing the original manual traditional operation mode, realizing mechanized replacement and automated reduction of manpower, while also greatly reducing and reducing the frequency of underground safety accidents.

[0003] The existing technology still uses the traditional manual operation mode to manually unload ore from the three unloading stations at the 40m level underground in the mine. The on-site environment is harsh (with a lot of dust). At the same time, the material level of the unloading station cannot be monitored in real time, and a lot of manpower and material resources need to be invested. Because the material level of the unloading station cannot be monitored in real time, it is also easy to cause the chute to be emptied. Unloading the ore in time is easy to cause a safety accident in which the chute of the unloading station is damaged by impact.

[0004] Therefore, it is necessary to develop an intelligent ore discharge control system for unloading stations, realize interlocking intelligent ore discharge control of underground mine unloading stations, and realize unmanned operation on site. Ensure that the material level of the unloading station is kept high in real time, prevent the unloading station from being damaged by impact when being emptied, extend the service life of the underground mine unloading station and improve the ore discharge efficiency. Summary of the invention

[0005] In order to ensure that the material level of the unloading station is kept high in real time, prevent the unloading station from being damaged by impact when being emptied, extend the service life of the underground mine unloading station and improve the ore discharge efficiency, and realize the interlocking intelligent ore discharge control of the underground mine unloading station, the present invention provides an intelligent ore discharge control system for the underground mine unloading station to realize unmanned on-site operation.

[0006] The present invention is accomplished by the following technical solutions:

[0007] An intelligent ore discharge control system for an underground mine unloading station includes a controller, wherein the controller includes a plurality of input terminals and output terminals;

[0008] The controller input end is connected to the field detection instrument, proximity switch, height detection encoder sensor and laser material level detection device;

[0009] The output end of the controller is connected to the chain brake lifting motor contactors of several unloading stations through corresponding resistors and intermediate relays.

[0010] Furthermore, the first and second output ends of the controller are connected to the intermediate relay and chain brake lifting motor contactor of the first unloading station through resistors, respectively, the third and fourth output ends are connected to the intermediate relay and chain brake lifting motor contactor of the second unloading station through resistors, and the fifth and sixth output ends are connected to the intermediate relay and chain brake lifting motor contactor of the third unloading station through resistors to control the chain brake lifting motor locomotive to lift, lower and stop.

[0011] Furthermore, the system also includes a plurality of cameras connected to the controller, and the cameras are installed at 6 material levels and a chain brake of the unloading station.

[0012] Further, a proximity switch is installed on the on-site chain brake lifting motor, and a high-precision encoder sensor is installed on the on-site chain brake lifting motor.

[0013] Furthermore, the controller is a Siemens PLC-S7 300 controller.

[0014] Furthermore, the Ethernet communication terminal of the controller is connected to the remote control host computer through a network cable, an industrial Ethernet switch and an optical cable.

[0015] Compared with the prior art, the present invention has the following advantages and effects:

[0016] The present invention can conveniently transmit the unloading station ore discharge information to the controller through on-site buttons, conversion switches, detection instruments, proximity switches, height detection encoder sensors, and laser material level detection devices. After processing and analysis by the controller, the chain brake hoisting electric locomotive is controlled to lift, lower, and stop. At the same time, through the 6 material level and chain brake video monitoring cameras of the unloading station within the 40m level, the material level and chain brake of the three unloading stations can be monitored in real time. Finally, the remote automatic interlocking intelligent control of the three unloading stations at the 40m level is realized to ensure that the material level of the three unloading stations is kept at a high level in real time, to prevent the unloading station from being damaged by impact, and to achieve unattended operation on site.
