FIG. 4 is a diagram illustrating an example of determination conditions by the determination unit of this embodiment. In the example shown in the figure, the type of alarm "warning occurrence" is associated with the first condition "a state in which a leakage current of 50 mA or more has occurred for more than 1 minute". The type of alarm "continuous warning" is associated with the first condition "a state in which a leakage current of 50 mA or more continues for 5 minutes or more". The type of alarm "insulated lock 50mA" is associated with the first condition "if the same item is detected three times within 30 minutes from the occurrence of the alarm". Satisfying the first condition indicates that an alert should be sent.
Further, the second condition "〇" is associated with the alarm types "continuous vigilance" and "insulation lock 50 mA". The second condition “〇” indicates that alarm data and sensor data should be transmitted.
In other words, if the first condition is met and the second condition is "〇", the alarm data and sensor data should be transmitted, and if the first condition is met and the second condition is unmarked, the alarm data should be sent. Indicates that data should be sent (sensor data should not be sent).

Returning to FIG. 3, the processed sensor data generation unit 1413 generates processed sensor data based on information indicated by sensor data including leakage current data. For example, the processed sensor data generation unit 1413 always generates processed sensor data that indicates the maximum value for one second within a period up to one hour ago for the period. Alternatively, the processed sensor data generation unit 1413 always generates processed sensor data that shows the average value for one minute within a period up to seven days ago. Alternatively, the processed sensor data generation unit 1413 generates processed sensor data indicating the daily maximum and minimum values of the Tr current (load current).

Thereafter, the information indicated by the sensor data is presented to an electrical safety engineer, a person managing the cubicle 10 by the sensor processing server 22, and the like.

Next, an example of processing executed by the gateway 14 will be described with reference to FIG.
FIG. 5 is a flowchart illustrating an example of processing executed by the gateway according to the embodiment. Note that the steps shown in FIG. 5 may be executed with the order changed to the extent possible, or may be omitted as appropriate.

In step S110, the first receiving unit 1411 receives leakage current data and time information from the leakage current sensor 11. In this case, the leakage current data received from the leakage current sensor 11 is given the time information transmitted from the leakage current sensor 11 as a time stamp.
Note that the first receiving unit 1411 may be configured to receive time information from the clock 146 in response to receiving leakage current data from the leakage current sensor 11. In this case, the first receiving unit 1411 receives time information from the clock 146. The first receiving unit 1411 associates the received leakage current data with time information. As a result, time information is added to the leakage current data as a timestamp.
That is, in either case of receiving leakage current data and time information from the leakage current sensor 11 or receiving leakage current data from the leakage current sensor 11 and time information from the clock 146, Time information is added to the leakage current data as a timestamp.
The leakage current data and time information received by the first receiving unit 1411 are collectively referred to as first data. That is, the first receiving unit 1411 receives leakage current data and time information as first data. Note that leakage current data is also referred to as earth leakage data for short.

In step S120, the determination unit 1415 determines whether the leakage current state indicated by the leakage current data satisfies the condition for issuing an alarm (for example, the first condition shown in FIG. 4).
In step S130, if the determination unit 1415 determines that the state of the leakage current satisfies the conditions for issuing an alarm (step S130; Yes), the process proceeds to step S140. If the conditions for issuing an alarm are not satisfied (step S130; No), the determining unit 1415 determines that the condition is normal and ends the process.

In step S140, the determining unit 1415 determines whether the type of alarm is a predetermined type (for example, the type where the second condition shown in FIG. 4 is "O"). The determination unit 1415 determines that sensor data should be transmitted when the type of alarm is a predetermined type, for example, "continuous alert" or "insulated lock 50 mA" (step S140; Yes), The process advances to step S150. When the type of alarm is not a predetermined type, for example, when it is "warning occurrence" (step S140; No), the determination unit 1415 determines that the sensor data is not to be transmitted, and advances the process to step S180.

In step S150, the processed sensor data generation unit 1413 checks the time (time stamp) of the first data received by the first reception unit 1411.
In step S160, the processed sensor data generation unit 1413 selects a predetermined time range (for example, the time of the first data) from among the sensor data stored in the data storage unit 1414 based on the time confirmed in step S150. Processed sensor data is generated by extracting the sensor data for the last one hour from the time of the stamp.
In step S170, the second transmitter 1417 adds management data for identifying the gateway to the processed sensor data generated in step S160, and transmits the processed sensor data to the sensor processing server 22.

Therefore, the gateway 14 can provide and utilize various information regarding the status of the cubicle to the electrical safety engineer. Moreover, this effect is produced even when the alarm processing server 21 and the sensor processing server 22 are independent from each other.

Further, the gateway 14 generates processed sensor data based on information indicated by the sensor data, and stores the processed sensor data in a storage medium. As a result, the gateway 14 collects information for a predetermined period back from the time when the alarm was issued, such as an electrical safety engineer, a person managing the cubicle 10, etc. who received the alarm from the alarm processing server 21. This makes it possible to confirm the situation and facilitate the implementation of effective measures against problems with the cubicle 10.
In addition, since the clocks of the devices in the cubicle are in a synchronized state, the time of alarm issuance and the extraction time of processed sensor data that goes back a predetermined period are synchronized. Therefore, according to the gateway 14 of the present embodiment, even if a situation arises in which alarms are issued randomly, for example, the alarms and processed sensor data can be stored in a state in which a correct response can be taken using management data and time data. You can check with.

Furthermore, if it is determined that the alarm indicated by the alarm data satisfies a predetermined condition, the gateway 14 transmits the alarm data, first cubicle data, and management data to the alarm processing server 21 . Thereby, the gateway 14 can transmit alarm data to the alarm processing server 21 when the need is relatively high.

Furthermore, if it is determined that the information indicated by the sensor data satisfies a predetermined condition, the gateway 14 transmits the sensor data and the second cubicle data to the sensor processing server 22 . This allows the gateway 14 to send sensor data to the sensor processing server 22 when the need is relatively high.
