In the portable data collection / analysis device configured as described above, the status display panel 18 displays the value of the currently collected data, the current time, and the like. Further, the status display panel 18 can display the setting contents for confirming the contents variously set by the mode change button 19. The maintenance hatch 20 is used to inspect equipment inside the device. Since the portable data collection / analysis device of the present invention is often used in a closed place such as inside a plant, the private communication device 21 is configured exclusively for private communication. When used in a normal outdoor or general place, data can be exchanged with an external facility using the sensor I / F 23 or the external I / F. In the storage battery storage unit 25,
A storage battery 8 as a device power supply is stored.

Next, the operation of the portable data collection / analysis device of the above embodiment will be described with reference to the flowchart of FIG. First, the portable data collection / analysis device is installed at an arbitrary location (step 27), and sound collection is started (step 28). At this time, the sound collector 7 generates an analog electric signal corresponding to the collected sound, that is, a sound collecting signal. This analog sound collecting signal is converted into digital sound collecting data by the A / D converter 6 (step 29). This sound collection data is stored in ROM4
Is analyzed by the CPU 2 in accordance with the analysis program stored in the CPU 2 and an abnormality is determined (step 30).
When an abnormality is detected, sound collection data is recorded in the recording memory 5 together with the abnormality information (step 31). At this time, time data obtained by the timer 15 can be added as needed.

In step 32, it is determined whether there is a request for external output. If not, the process returns to step 29,
The sound collection is analyzed again based on the sound collection signal. If there is an external request, the data is transmitted via the external IF (any of I / Fs 10 to 14) (step 33), and the process ends.

In the above-described embodiment, various sensors can be connected to the sensor I / F 9. When data from these sensors is received, the collected data is stored in the ROM 4 and stored in the ROM 4 in accordance with an analysis program corresponding to the collected data from the sensors.
PU2 analyzes.

According to the above embodiment, the presence or absence of an abnormality is determined based on the acquired sound collection data, and the data to which the abnormality determination is added is directly transmitted to the outside. However, communication may not be possible to the outside due to some circumstances. In this case, the data is stored in the recording memory 5 provided inside the apparatus, and when communication is restored, data can be downloaded from the outside or transmitted using an external I / F of the apparatus. Such an embodiment will be described with reference to the flowchart of FIG.

FIG. 4 shows steps 27 to 30.
The operation is the same as that described above, but in step 35, abnormal information is added to the data. Next, it is determined in step 36 whether external communication is possible, and if possible, data is transmitted to the outside (step 37). If communication is not possible, the data to which the abnormality information has been added is stored in the recording memory 5 (step 38).

At step 39, an end condition is determined, and if the end condition is satisfied, the process ends. If the termination condition is not satisfied, the process returns to step 29 and the data collection is continued.

When the acquired data is directly communicated with the external device, if the data is missing, the data cannot be acquired forever. However, in the embodiment of FIG. 5, when communication to the outside is impossible for some reason, data can be stored in the recording memory 5 inside the apparatus. Can be taken in, and data loss can be prevented.

Next, an embodiment in which all the acquired data is not sent will be described. In this embodiment, the data acquired by the sound collector is analyzed by the analysis program, and as a result, if there is no abnormality, the communication to the outside is not performed, and the data is recorded in the internal recording memory 5. do not do.
However, if any abnormality is detected, the data is transmitted to the outside or the data is recorded in the internal recording memory 5 together with the abnormality information. The operation of this embodiment will be described with reference to the flowchart of FIG.

Steps 27 to 30 are the same as those in FIGS. In step 40 following step 30, it is determined whether there is an abnormality. If there is no abnormality, that is, if NO, the process returns to step 29 and data collection is continued. If there is an abnormality, that is, if YES, abnormality information is added to the data (step 3).
5). Next, it is determined whether external communication is possible (step 36). If the determination is YES, the data is transmitted to the outside. If the determination is NO, the data is recorded in the recording memory 5 (step 38). After step 37 or 38, it is determined whether the termination condition is satisfied (step 3).
9). If the determination is YES, the process ends. If the determination is NO, the process returns to step 29 and data collection is continued.

According to the embodiment shown in FIG. 6, when not all the acquired data but only the data at the time of some abnormality are transmitted to the outside, the amount of data to be transmitted to the outside or the internal recording memory The amount of data to be recorded can be reduced. However, judgment by the abnormality analysis program is important. In this embodiment, not only the abnormality analysis program previously stored in the ROM 4 but also a new RAM 3
Since a new analysis program can be stored in the storage device, the accuracy of data analysis can be improved.

Next, a data collection / analysis device used for seismic intensity measurement, that is, a portable seismic intensity measuring device will be described as another embodiment of the present invention. In seismic intensity observation of earthquakes, if there are many observation points and it is not possible to fix the measurement points, a pattern of installing data at a certain place at a fixed interval and moving to the next place and collecting data will be repeated. Many. In this case, there is often no power supply at the place where the measuring device is installed, and the device is operated only by the internal storage battery. Since the operation time of the storage battery is limited, it is necessary to reduce the power consumption of the measuring device as much as possible. Therefore, in the portable seismic intensity measurement device of the present embodiment, a data collection method is adopted so that the communication / recording operation is performed only when an abnormality occurs.

The portable seismic intensity measuring apparatus of this embodiment is basically configured in the same manner as the configuration shown in FIGS. However, the cabinet has a drip-proof and dust-proof structure so that it can be sufficiently used outdoors. As for the operation of the seismic intensity measuring device, a data collection method for performing data communication and data recording only at the time of an abnormality is employed, similarly to the operation shown in the flowchart of FIG.

In order to increase the duration of the storage battery, it is necessary to separately perform operations of data acquisition, abnormality analysis, and data transmission (recording) to eliminate unnecessary portions. According to this embodiment, since the data transmission (recording) is performed separately, labor can be saved. In addition, by adopting a drip-proof and dust-proof structure, it can be installed outdoors and can be used in places with severe weather conditions.

[0029]

As described above, according to the present invention, since the data collection / analysis portion is portable, it can be installed at an arbitrary place to collect data. In addition, the installation location can be easily changed at regular intervals. Furthermore, since various sensors can be attached, it can be widely used from sound analysis to specific frequency analysis or earthquake measurement. In addition, since the program analysis can be stored not only in the ROM but also in the RAM, it is versatile and can be used when a new algorithm or processing method is developed.
