Abstract:
1. A mining machine information collection system comprising: an in-vehicle information collection device that is provided in a mining machine and collects operation information about an operation state of the mining machine; a position information detecting device that is provided in the mining machine and detects position information about a position of the mining machine; a first wireless communication device that is provided in the mining machine and performs communication; and an information collection device that collects the operation information through a second wireless communication device which communicates with the first wireless communication device, wherein the information collection device transmits a position information request command to request a transmission of the position information of the mining machine through the second wireless communication device at a predetermined time, and the information collection device determines whether the mining machine whose response to the position information request command is received by the second wireless communication device in a communication range of the first wireless communication device until a communication of the operation information of the mining machine ends, and when the information collection device determines the mining machine whose response to the position information request command is received by the second wireless communication device is in the communication range of the first wireless communication device until the communication of the operation information of the mining machine ends, the information collection device collects the operation information of the mining machine whose response is received, and the information collection device determines whether the mining machine whose response is received can stay in the communication range until the communication of the operation information of the mining machine ends, based on the position information, a speed and a traveling direction of the mining machine whose response is received of the mining machine, communication time of the operation information, and position information about the communication range.
