Description

  The present invention relates to a mining work information collection system, and more particularly to a mining work information collection system and a collection method capable of collecting information without a fixed communication infrastructure.

  As a known technique for collecting information related to the mining operation, for example, there is a mining method disclosed in Patent Document 1. In this mining method, after a drilling machine located at the mining site drills a hole for blasting, the hole is loaded with explosives and blasted, and the crushed ore is loaded onto a dump truck with a loading shovel. . During these operations, the drilling machine and the loading excavator communicate with the base station, and the mining operation is performed while creating a distribution map of ore quality and the like.

  On the other hand, as a routine work in a mine, there is a task of transporting products such as ore from a mining site to a treatment plant. In order to perform work management of this work, it is necessary to collect various information such as mining position, mining equipment (mining equipment), transport equipment (transport heavy equipment), transport start time, transport end time, processing equipment, etc. .

  In order to collect such various types of information, it is necessary to transmit various types of information from a heavy machine that performs mining operations to a device that accumulates information, and a wireless communication system is usually used. However, the office of a treatment plant with a device for storing various information is usually far away from the mining site, and is often not within a range where radio waves transmitted from the mining site can reach directly. In addition to the distance, there are many cases where radio waves from the mining site do not reach due to the influence of topography. Direct communication may be possible if a large-scale wide-area infrastructure such as a cellular phone network is used, but it is difficult to adopt in practice because it requires investment of large-scale independent facilities or communication charges. .

  When mine heavy equipment performs data communication, wireless LAN (802.11b, 802.11g) is widely used. However, in order to transmit data from a mining site to an office of a treatment plant using a wireless LAN, the mining site and the office must be in a state where they can be connected to a wireless LAN. It is necessary to install a wireless LAN access point. In other words, when the mining site and the office of the treatment plant are far apart, communication in the ad hoc mode cannot be expected, and the infrastructure mode is essential.

  However, since the mining site changes from day to day, the area to be covered varies, and the shape of the mine itself also changes due to mining, it is practically difficult to keep fixed wireless LAN access points properly arranged.

[Example]
Next, a specific embodiment of the present invention will be described with reference to FIG. Also in FIG. 2, for convenience, only one mining heavy machine 110 and one transporting heavy machine 120 are shown, but these are not limited to one, and the processing site is not limited to one.

  As shown in FIG. 2, the mining heavy machine 110 in the mining place P1 is a mining information acquisition unit including a GPS 111-1 for acquiring the mining position and the mining time as the mining information acquisition unit 11 shown in FIG. 111 and a wireless communication device 112 as the mining information transmission means 12 shown in FIG. Similarly, the transport heavy machine 120 includes a transport information acquisition unit 121 including a GPS 121-1 for acquiring a transport start / end position and a transport start / end time as the transport information acquisition unit 21 shown in FIG. The mining information receiving means 22 and the mining work information transmitting means 24 shown in FIG. The transporting heavy machine 120 is also provided with a memory 123 as the mining work information storage means 23 shown in FIG.

  The transport heavy machine 120 starts the ore loading operation in the state of being close to the mining heavy machine 110, acquires the transport start position, the transport start time, the name of the person in charge of transport, the transport heavy machine ID, and transports the transport amount and the like. Start acquiring information. The acquired transportation information is stored in the memory 123. The loading operation start is recognized manually or automatically by the transporting heavy machine 120, the nearest mining heavy machine is recognized as the mining heavy machine that is loading the ore, and the mining information is sent to the corresponding mining heavy machine. Request transmission. It goes without saying that the ID of the mining heavy equipment is attached to this transmission request, but in the case of manual operation, the mining heavy equipment is recognized by the operator of the transporting heavy equipment 120 and the mining heavy equipment ID is input. The On the other hand, in the case of automatic recognition, the following method is adopted.

  At the start of the ore loading operation, the driver of the transporting heavy machine 120 presses a predetermined button on the driver's seat. At this time, a message is transmitted so as to report the received electric field strength of the radio wave from the transport heavy machine 120 to all mining heavy machines around which the radio communication device 122 of the transport heavy machine 120 is located (within the communication range). The radio communication device of each mining heavy machine that has received this message adds its own ID and returns a signal indicating the received electric field strength. The wireless communication device 122 of the transporting heavy machine 120 waits for an answer for a certain period of time, and uses the ID of the mining heavy equipment that has declared the strongest received electric field strength among the received messages indicating the multiple electric field strengths as the destination of the loading operation. recognize. In addition to the received electric field strength from the mining heavy equipment, the received electric field strength when the return message is received by the heavy transport equipment 120 may be taken into consideration. That is, you may make it recognize the other party of loading work based on the average value of the received electric field strength from the mining heavy equipment and the received electric field strength when the reply message is received.

  Instead of the automatic recognition method using the received electric field intensity, an automatic recognition method using calculation based on GPS position information may be adopted. For example, by using the same method as described above, the position information is returned to all mining heavy machines within the communication range, and the closest received position information is recognized as a loading work partner.

  As the mining information, in addition to the mining position and mining time acquired by the GPS 111-1, the name of the person in charge of mining, the mining heavy equipment ID, the mining amount, etc. are stored in the memory in the mining information acquisition means 111, and transmission of the mining information is performed. The mining heavy equipment 110 requested to transmit the mining information to the transporting heavy equipment 120 that has requested transmission of the mining information by the wireless communication device 112. The transmission request transmitted from the transporting heavy machine 120 includes its own ID, as well as the ID of the mining heavy machine 110 that requests transmission as described above. It goes without saying that the mining information transmitted from the mining heavy equipment 110 is also given the ID of the mining heavy equipment 110 that requested transmission, in addition to its own ID.

  The transporting heavy machine 120 that has received the mining information from the mining heavy machine 110 accumulates the received mining information in the memory 123. As described above, in the memory 123, the transportation start position, the transportation start time, the name of the person in charge of transportation, the heavy equipment ID are stored as the transportation information acquired by itself, and the transportation amount is acquired as other transportation information, This is also stored in the memory 123.

  When the loading operation is completed, the acquisition of mining information and transport information is also completed, and the transport heavy machine 120 starts moving to transport the ore. Thereafter, the heavy equipment for transportation 120 ′ arriving at the ore treatment plant P <b> 2 loads ore. At the point of time when loading or unloading of the ore is started, the transport information acquisition means 121 of the transport heavy machine 120 ′ additionally acquires transport information. The additionally acquired transportation information includes the transportation end position, the transportation end time, the ID of the wireless access point at the loading / unloading position, etc. acquired by the GPS 121-1.

  Here, the loading and unloading wireless access point will be described with reference to FIG. In FIG. 3, a plurality of treatment plants 1, a treatment plant 2 (referred to as a treatment plant P2 in FIG. 2), and a treatment plant 3 are shown as treatment plants, and one wireless access point is set at the ore loading / unloading location of each treatment plant. ing. There may be a plurality of wireless access points in one processing place, but a different ID is assigned to each wireless access point. In FIG. 3, ID “101” is assigned to the wireless access point of the processing place 1, ID “102” is assigned to the wireless access point of the processing place 2, and ID “103” is assigned to the wireless access point of the processing place 3. . Each wireless access point is connected to the information collecting apparatus 130 in the office outside the processing site via a wired network, but may be configured as a wireless network instead of the wired network.

  The wireless communication device 123 ′ of the transport heavy machine 120 ′ automatically recognizes the ID of the loading and unloading wireless access point in the same manner as the automatic recognition of the mining heavy equipment described above. As described above, this recognition may also be manually designated by the driver of the transporting heavy machine 120 ', or the closest wireless based on the positional information from each wireless access point and its own positional information by GPS. The access point may be automatically recognized. The ID of the recognized wireless access point is acquired as the transport destination information in the transport information acquiring means 121 '.

  In any case, at the start of unloading of the ore at the treatment plant P2, the transporting heavy machine 120 ′ adds the transportation information additionally acquired at the treatment plant P2 to the mining operation information collected at the mining site P1. Is transmitted to the information collecting apparatus 130 via the wireless access point (ID “102”) of the processing place P2. The start of unloading of the ore is recognized manually or automatically by the transporting heavy machine 120 '. A fixed wired or wireless network is configured between the processing site P2 where the loading and unloading work is performed and the information collecting apparatus 130, and information communication is possible.

  Every time ore is loaded and unloaded in this way, information on the mining work and information on the treatment plant is collected.
