1. A data transmission system for a work machine comprising:
a processor, the processor being configured to:
receive processing definition information indicating details of processing of data collected from the work machine;
determine a data format to be processed, based on the received processing definition information, and process the data collected from the work machine based on the determined data format; and
transmit the processed data to an external device, wherein the processing definition information includes at least information indicating a type of the data format to be processed,
wherein the processor processes the data in accordance with the information indicating the type of the data format designated in the processing definition information,
wherein the processor further creates trend-type data recorded for each aggregation period designated in the processing definition information, in accordance with the information indicating the type of the data format,
wherein the processing definition information further includes data items indicating types of data to be processed, and a processing method indicating at least one of an average value, a maximum value, or a minimum value corresponding to the data items, and
wherein the processor processes each of the data collected in the aggregation period according to the processing method which is indicated, for each of the types of data designated in the data items.
 
12. A data transmission method for a work machine comprising:
a step of receiving processing definition information indicating details of processing of data collected from the work machine;
a step of determining a data format to be processed, based on the received processing definition information, and processing the data collected from the work machine based on the determined data format; and
a step of transmitting the processed data to an external device,
wherein the processing definition information includes at least information indicating a type of the data format to be processed,
wherein the processor processes the data in accordance with the information indicating the type of the data format designated in the processing definition information,
wherein the processor further creates trend-type data recorded for each aggregation period designated in the processing definition information, in accordance with the information indicating the type of the data format,
wherein the processing definition information further includes data items indicating types of data to be processed, and a processing method indicating at least one of an average value, a maximum value, or a minimum value corresponding to the data items, and
wherein the processor processes each of data collected in the aggregation period according to the processing method which is indicated, for each of the types of data designated in the data items.
