PROBLEM TO BE SOLVED: To provide a telemeter device capable of accumulating sufficient data amounts before and after the occurrence of the abnormality of data indicating the state of site equipment collected from the site equipment.SOLUTION: The process measurement data of site equipment and a contact signal 4 indicating the state of the site equipment are input by a data input part by high speed sampling, and the input data are transmitted via a communication line 5 to central monitoring equipment 2 by a communication sampling part 18 and a communication control part 19a, and stored in a normal storage area 15a. The presence/absence of the bit change of the contact signal 4 is verified by a data verification part 12, and when the normal storage area 15a becomes full, the data stored in the normal storage area 15a are moved to and stored in a saving area (2) 15d with large capacity with the bit change as a trigger, and the data of the saving area (2) 15d are transmitted to the central monitoring equipment 2 in response to a request from the central monitoring equipment 2. |
