The operation contents of the information transmitting apparatus 2 and the telephone module 3 have been described above by taking the case of using a commercially available answering machine 4 as an example. Of course, the operation content of the adapter 3 is changed. The circuit configuration of the telephone adapter 3 is not limited to that shown in FIG. 3, but may be any other configuration as long as it corresponds to the operation of the answering machine 4. In the description of FIGS. 9 and 10, the operation of the telephone adapter 3 is started after the recorded message created by the information transmitting device 2 is transferred to the telephone adapter 3. However, the present invention is not limited to this. After the operation of the adapter 3 is started, the recorded message may be transferred at a necessary timing. In this case, data exchange between the telephone adapter 3 and the information transmitting device 2 is required, but it is excellent in that the memory capacity of the telephone adapter 3 is small. Further, since the information transmission device 2 can be configured by a personal computer, the CPU 7 and the memory 6 of the telephone adapter 3 can be realized by the CPU and the memory of the information transmission device 2, and in this case, the data input unit 5 and the CPU 7 , And the memory 6 can be omitted. As described above, in this embodiment, the abnormality monitoring system is applied to the substation equipment.
The application target can be changed appropriately without departing from the spirit of the invention.
