METHOD OF MEASURING TEMPERATURE DISTRIBUTION OF STORED COAL, METHOD OF PREVENTING SPONTANEOUS COMBUSTION IN STORED COAL, AND TEMPERATURE DISTRIBUTION MEASURING SYSTEM OF STORED COAL
METHOD OF MEASURING TEMPERATURE DISTRIBUTION OF STORED COAL, METHOD OF PREVENTING SPONTANEOUS COMBUSTION IN STORED COAL, AND TEMPERATURE DISTRIBUTION MEASURING SYSTEM OF STORED COAL
PROBLEM TO BE SOLVED: To provide a method of measuring a temperature distribution in stored coal for precisely measuring temperature of a center of stored coal, a method of efficiently preventing spontaneous combustion in stored coal, and a temperature distribution measuring system of stored coal.SOLUTION: This temperature distribution measuring method of stored coal includes a process of embedding, in stored coal, a plurality of RFID tags each having a temperature sensor and for transmitting temperature information measured by the temperature sensor together with its tag ID information (identification information) by means of a radio wave having a frequency of 1 GHz or less, a process of generating a database in which at least embedded positions of the RFID tags embedded in the stored coal and the tag ID information are recoded, and a process of collating a result obtained by specifying at least the tag ID and the temperature based on the database and the received radio wave of the RFID.
