The management data is information associated with contract information and the like in the alarm processing server 21 and the sensor processing server 22. The alarm processing server 21 and the sensor processing server 22 can identify cubicles based on management data.

The second transmitter 1417 adds management data for identifying the gateway 14 to the processed sensor data and time information, and transmits the processed sensor data and time information to the sensor processing server 22 . The sensor processing server 22 is used to receive information based on the results detected by the sensors installed in the cubicle 10, and to present the information to at least one of an electrical safety engineer and a building manager.

Next, an example of processing executed by the gateway 14 will be described with reference to FIGS. 6 and 7.
FIG. 6 is a flowchart illustrating an example of sensor data reception processing by the gateway according to the embodiment. Note that the steps shown in FIG. 6 may be executed with the order changed to the extent possible, or may be omitted as appropriate.

In step S110, the second receiving unit 1412 of the gateway 14 performs communication connection processing with the interface box 13.

If the second receiving unit 1412 determines to stop transmitting sensor data (step S180; Yes), it ends the process. When the second receiving unit 1412 determines that the transmission of sensor data is not stopped (step S180; No), the process returns to step S140 and continues the process.

FIG. 7 is a flowchart illustrating an example of processing for transmitting processed sensor data by the gateway according to the embodiment. Note that the steps shown in FIG. 7 may be executed with the order changed to the extent possible, or may be omitted as appropriate.

In step S210, the second transmitter 1417 of the gateway 14 performs communication connection processing with the sensor processing server 22.
In step S220, the gateway 14 determines whether a transmission command from the sensor processing server 22 has been received. If the gateway 14 determines that it has received the transmission command from the sensor processing server 22 (step S220; Yes), it advances the process to step S230. If the gateway 14 determines that it has not received the transmission command from the sensor processing server 22 (step S220; No), the process returns to step S220 and continues determining whether the transmission command has been received.

In step S230, the gateway 14 decodes the transmission command from the sensor processing server 22. As an example, the gateway 14 deciphers the transmission command by comparing the transmission conditions shown in FIG. 5 with the received transmission command.
In step S240, the gateway 14 reads the processed data and time information according to the transmission command from the data storage unit 1414.
In step S250, the second transmitting unit 1417 of the gateway 14 adds management data to the read processed data and time information, and transmits them to the sensor processing server 22.

The first transmitter 1416 adds management data for identifying the gateway to the alarm data and time information, and transmits the data to the alarm processing server 21 . The second transmitter 14171 transmits the processed sensor data, time information, and management data that identifies the gateway to the sensor processing server 22 . Thereby, the gateway 14 can provide the electrical safety engineer with a variety of information regarding the state of the cubicle in an appropriate format for use.

FIG. 8 is a diagram illustrating an example of how processed data is used according to the embodiment.
The processed data name "immediate information" is generated in the gateway 14 and is used to check the situation at the time of occurrence, such as when an alarm is issued or an abnormal situation occurs.
Processed data name "Medium-term information" is generated in the gateway 14 and is used to confirm the actual situation in more detail when an alarm is issued, abnormal situation, inspection, etc. It is used for determining whether or not.
The processed data names "daily information,""monthlyinformation," and "annual information" are all used to check medium- to long-term fluctuations, deterioration over time, etc. Here, the "daily information" is generated at the gateway 14 as described above. On the other hand, "monthly information" and "annual information" are generated in the sensor processing server 22 based on "daily information" transmitted from the gateway 14.
That is, the gateway 14 and the sensor processing server 22 share and generate multiple types of processed data depending on the purpose of use.

FIG. 9 is a diagram illustrating an example of a usage pattern of last-minute information according to the embodiment. The figure shows, as an example of displaying information for the last hour, search results for sensor data searched by specifying management data and graph type. By using the above-mentioned immediately before information, it is possible to graphically show the transition of each sensor data such as leakage current, load current (Tr current), load voltage (Tr voltage), etc. immediately before the alarm is issued.
FIG. 10 is a diagram illustrating an example of how annual information is used according to the embodiment. The figure shows, as an example of yearly display, the search results of sensor data searched by specifying management data, search target year, and graph type. By using the above-mentioned annual information, it is possible to graph and show the annual trends of each sensor data such as leakage current, load current (Tr current), load voltage (Tr voltage), etc.

By separating the processing locations of the processed data as described above, the gateway 14 does not have to process and hold all of the data, reducing the processing/work load on the gateway 14 and the communication load between the gateway 14 and the sensor processing server 22. It is also planned.
If the "monthly information" were to be generated by the gateway 14, problems would arise such as the need to secure memory capacity on the gateway 14 side and the time required for one transmission. Furthermore, if the sensor processing server 22 creates the "medium-term information", the sensor processing server 22 and the gateway 14 must communicate on a minute-by-minute basis. Therefore, by splitting the burden so that the gateway 14 generates up to daily information and the sensor processing server 22 generates "monthly information" and "annual information," the load on both the gateway 14 and the sensor processing server 22 is reduced. A system configuration can be achieved.

Although we have described an example in which the processed data generation unit processes and generates sensor data, it is also possible to generate processed data that includes leakage data acquired from a leakage current sensor in addition to sensor data. good. Since the leakage data is also transmitted along with the time information, it can be handled in the same way as sensor data, and therefore can be processed in the same way as other sensor data.

Furthermore, at least some of the functions of the gateway 14 shown in FIG. It may be realized by hardware including circuitry. Alternatively, at least some of the functions of the gateway 14 shown in FIG. 3 may be realized by cooperation of software and hardware. Furthermore, these pieces of hardware may be integrated into one piece, or may be divided into a plurality of pieces.
