In FIG. 3, the center 10 is provided with a remote monitoring device 11 that monitors the operating state of the facility 1 installed at a remote place and generates a daily report based on the operation data of the facility. On the other hand, in the remote area 20 where the equipment 1 is installed (hereinafter referred to as “local”), the temperature and pressure are detected by the sensors 2 attached to one or more parts of the equipment 1, and these are detected. A data collection device with a remote monitoring function (hereinafter referred to as “equipment operation data collection device”) 4 for collecting data via the AD converter 3 is installed. When data such as temperature collected by the facility operation data collection device 4 is collectively referred to as operation data, the operation data is sent to the remote monitoring device 11 via the modem 5, the public line network 6, and the modem 12. The remote monitoring device 11 generates a daily report based on the operation data sent, and the personal report (PC) 8 installed in the same local 20 as the equipment 1 through the modem 13, the public line network 6, and the modem 7. Send to e-mail. The remote monitoring device 11 is normally connected to a plurality of locally installed facility operation data collection devices 4 and PCs 8 by contract, but the basic configuration of the device disposed in each local 20 is the installation of the facility 1. Since it is the same regardless of the number, only one local 20 is shown in FIG.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, since the whole structure of the equipment remote monitoring system in this Embodiment may be the same as the past, it will use FIG. 3 as it is. In the present embodiment, the contents of the daily report generation process in the remote monitoring device 11 according to the difference in the functional configuration of the facility operation data collection device 4, the number of communication with the facility operation data collection device 4, and the configuration of the operation data sent thereto. Is different.
[0012]
FIG. 1 is a block configuration diagram of an equipment operation data collection device 4 in the present embodiment. The equipment operation data collection device 4 in the present embodiment includes a data collection unit 41, a data holding unit 42, a data management unit 43, and a data transmission unit 44. The data collection unit 41 collects operation data such as temperature and pressure detected by the sensor 2 attached to the facility 1 via the AD converter 3 and accumulates it in the data holding unit 42. The data management unit 43 causes the data transmission unit 44 to transmit the operation data accumulated in the data holding unit 42. In the present embodiment, however, only the operation data at a preset inspection time is transmitted to the center 10. This is one of the features. Further, when the equipment is not operated at a preset inspection time, the equipment operation time specified according to a predetermined rule is set as the inspection time, and only the operation data at the set inspection time is sent to the center 10. Another feature is that it is transmitted.
[0013]
As described above, in the present embodiment, it is necessary to set the inspection time in advance before the remote monitoring device 11 generates a daily report. In the conventional daily report generation processing, all the operation data collected by the facility operation data collection device 4 is transmitted to the center 10, and the center 10 obtains an average value based on the transmitted time-series operation data. However, as data for knowing the operation state of the facility 1, the operation data measured at a certain point in time or the transition of the operation data is handled as the facility daily report. That is, from the viewpoint of monitoring the operating state of the facility 1, the average value of the actually measured values that changes from moment to moment is actually not meaningful. Therefore, instead of transmitting all the collected operation data to the center 10 and extracting the operation data to be included in the daily report at the center 10, in this embodiment, the operation data necessary for generating the daily report is extracted at the local 20 I tried to make it. In other words, the amount of data transmission is reduced by transmitting only the operation data included in the daily report to the center 10. Thereby, when data transmission is performed via the public network 6, the communication cost can be reduced. In addition, since only the minimum necessary operation data to be posted in the daily report is sent to the center 10, the amount of data accumulated until the daily report is generated can be greatly reduced. Since it is not necessary to extract the operation data used for daily report generation from the operation data thus obtained, the daily report can be generated by simpler processing.
[0014]
As described above, in the present embodiment, the operation data to be transmitted to the center 10 is specified by specifying the operation data collection time. The time at which the operation data to be transmitted is collected is referred to as the inspection time. Yes. The number of inspection times set in the inspection time and the data collection period (“1 day” in the case of daily reports) can be arbitrarily set according to the type, specifications, characteristics, operation, etc. of the equipment 1 to be monitored. Furthermore, it may be set with reference to the processing capacity in the center 10, the number of facilities 1 in the entire system, etc., but basically it is desirable to set inspection times once to four times a day. In the present embodiment, the data management unit 43 performs the inspection time setting process and holds the set contents therein.
[0015]
Next, the flow of processing in the present embodiment, which is performed from the collection of operation data until the daily report is sent to the PC 8, will be described.
[0016]
In the local 20, the data collection unit 41 of the facility operation data collection device 4 collects the operation data detected by the sensor 2 and stores it inside. In the present embodiment, since the inspection time is specified in advance, the operation data at the minimum inspection time may be accumulated in the data holding unit 42. The operation data collected at the inspection time is transmitted to the center 10. However, when a plurality of inspection times are set, taking into consideration communication efficiency and cost, one day after the operation data collection at the last inspection time of the day. It is desirable to transmit the operation data for the minute. The processing in the equipment operation data collection device 4 can be automatically executed by setting the inspection time in advance.
[0017]
The remote monitoring device 11 once holds the operation data transmitted from the facility operation data collecting device 4 inside, but since only the operation data at the inspection time is sent from each local 20, the data storage amount is conventional. It is greatly reduced compared to. A daily report is generated based on the operation data without any special data processing or editing, and this is electronically transmitted to the PC 8 installed in the same local 20 as the equipment 1 via the modem 13, the public line network 6, and the modem 7. Send using e-mail.
[0018]
According to the present embodiment, the operation data used for creating the daily report is specified and transmitted in the facility operation data collection device 4 by setting the inspection time in advance as described above, and thus transmitted to the center 10. The amount of data can be reduced. Thereby, it is possible to reduce the communication cost via the public line network 6. Further, the daily report generation process in the center 10 can reduce the storage amount of the operation data, and it is not necessary to extract the operation data used for generating the daily report from the operation data sent to the daily report generation process. Can be done efficiently.
[0019]
By the way, in the said description, it demonstrated on the assumption that the installation 1 was driving | operating at the inspection time. However, the equipment 1 may stop at the inspection time for some reason. If it is not in operation, since the operation data collected at that time is not valid, the daily report based on this operation data has no meaning.
[0020]
Therefore, in this embodiment, in such a case, processing is performed as follows.
[0021]
That is, the data management unit 43 constantly monitors the operation status of whether or not the facility 1 is in operation by monitoring power supply to the facility 1 or power consumption. FIG. 2 is a diagram showing the operation status of the equipment. As shown in FIG. 2A, when the equipment 1 is in operation at the preset inspection time T, the operation data at that time may be transmitted to the center 10 as described above. Here, as illustrated in FIG. 2B, the following processing is performed in consideration of the case where the facility 1 is not in operation at the inspection time T. First, when the inspection time T is set, a period called a search target period during operation is also set accordingly. In the present embodiment, a total of 20 minutes before and after the inspection time is set as the in-operation search target period. The search target period during operation may be set to an appropriate period depending on the operation characteristics of the equipment 1 to be monitored, the type of report to be generated (daily report in this example), and the like.
[0022]
When the equipment 1 is not in operation at the inspection time T, the data management unit 43 detects the time of operation during the in-operation search target period, and sets a certain time point during the operation as the inspection time. . As shown in FIG. 2B, when there is a period during operation, the central point in the period during operation is set as the inspection time T ′. In addition, when there are a plurality of operating periods such as ta and tb in FIG. 2B, the one closer to the inspection time T is adopted. As described above, when the facility 1 is not operated at the preset inspection time T, the inspection time is changed from T to T ′ according to the predetermined rule as described above.
[0023]
In the above description, it has been described that the operation data at the inspection time should be collected and held at the minimum on the assumption that the facility 1 is in operation at the inspection time. However, as illustrated in FIG. In addition, in order to transmit the operation data at the time T ′ past the inspection time T to the center 10, it is necessary to collect the operation data periodically at least during the search target period.
[0024]
According to the present embodiment, the inspection time can be set in advance on the local side, and the inspection time set in advance considering the stop of the facility 1 can be changed.
[0025]
In the present embodiment, the case of generating a daily report has been described as an example. However, the report to be generated is not limited to the daily report, and may be a weekly report, a monthly report, or a different type of report. Further, each local 20 collects operation data and transmits it to the center 10 in order to generate a report. However, the method described above can be applied to the case where the center 10 collects operation data for other purposes. It is possible to achieve the effect of reducing the amount of data communication and the like as described above.
[0026]
【The invention's effect】
According to the present invention, since the operation data used for generating the report is specified and transmitted on the facility operation data collection device side by setting the inspection time in advance, the amount of data to be transmitted to the remote monitoring device is reduced. Can be reduced. Thereby, when transmitting data via a public line, it is possible to reduce the communication cost.
[0027]
In addition, the daily report generation process at the center can reduce the amount of operation data stored, and the facility operation data collection device sends only the operation data necessary for report generation. Therefore, it is not necessary to extract corresponding operation data from the operation data, and daily report generation processing can be performed efficiently.
