Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when transmitting and accumulating measurement data of cubicles to a server arranged on the cloud, if the amount of information to be transmitted is increased, the communication cost and the data storage capacity on the server increase. Therefore, measures have been taken to reduce the amount of information, such as lengthening the data transmission cycle. Therefore, when a state occurs where the monitored data deviates from the allowable range, there has been a problem that it is difficult to investigate the cause because the data acquisition cycle is set long.

[0005] Therefore, in view of such problems, an object of the present invention is to provide a cubicle management system that shortens the data acquisition cycle when an abnormality is detected.

Means for Solving the Problems

[0006] In order to solve the above problems, the cubicle management system according to the invention of claim 1 includes a management server disposed on the cloud for storing the state information of the cubicle housing the high-voltage power receiving equipment, and an in-cubicle management device for obtaining the state information and transmitting it to the management server. The in-cubicle management device includes data collection means for measuring and collecting physical data including the voltage measurement value and current measurement value of a predetermined part of the cubicle, which are part of the state information, transmission control means for managing the collection period of the physical data collected by the data collection means and transmitting the collected physical data to the management server, and a determination unit for determining whether the physical data is normal or abnormal. The transmission control means transmits to the management server at a predetermined first period if all the measured physical data is within the normal range. However, if there is physical data determined to be an abnormal value by the determination unit, only the physical data indicating the abnormal value or all the collected physical data is measured at a second period shorter than the first period and transmitted to the management server. Leakage current information of specific parts Together with the leakage current information, the management server has a weather information acquisition unit that acquires weather information. When the determination unit determines that the leakage current information is an abnormal value, it obtains the weather information of the area where the cubicle with the abnormal value is installed, associates it with the measured leakage current data that is the leakage current information, and stores it characterized in that. According to this configuration, at least for the part where the measured physical data shows an abnormal value, the period for measurement and transmission to the management server is shortened, so it is easy to investigate the cause and easy to manage the cubicle. In addition, since the leakage current value that is likely to vary depending on the weather conditions is stored together with the weather information when it shows an abnormal value, it becomes easier to investigate the cause

[0007] The invention of claim 2 is There is a management server arranged on the cloud that accumulates the state information of the cubicles housing high-voltage power receiving facilities, and a management device inside the cubicle that obtains the state information and transmits it to the management server.

There are data collection means for managing the collection period of the physical data collected by the data collection means, transmission control means for transmitting the collected physical data to the management server, and a determination unit for determining the normality / abnormality of the physical data. The transmission control means transmits to the management server at a predetermined first period if all the measured physical data is within the normal range. However, if there is physical data determined to be an abnormal value by the determination unit, only the physical data showing the abnormal value or all the collected physical data is measured at a second period shorter than the first period and transmitted to the management server. In addition, when the determination unit determines that the power factor on the high-voltage side is an abnormal value, the transmission control means sets the calculation and transmission period of the power factors on a plurality of low-voltage sides to the second period in addition to the power factor on the high-voltage side characterized in that. According to this configuration, At least for the part where the measured physical data shows an abnormal value, in order to shorten the period of measurement and transmission to the management server, it is easier to investigate the cause and manage the cubicle In addition, since the power factor on the low-voltage side is also monitored when the power factor on the high-voltage side deteriorates, it is easy to identify the cause

[0008] The invention of claim 3 is based on claim 1 in the configuration described in The data collection means has a power factor calculation unit that calculates the power factor on the high-voltage side and the power factors on a plurality of low-voltage sides as one of the physical data. The transmission control means, when the determination unit determines that the power factor on the high-voltage side is an abnormal value, in addition to the power factor on the high-voltage side, sets the calculation and transmission period of the power factors on a plurality of low-voltage sides to the second period According to this configuration, Since the power factor on the low-voltage side is also monitored when the power factor on the high-voltage side deteriorates, it is easy to identify the cause

[0009] The invention of claim 4 is based on claim 2 in the configuration described in The transmission control means is characterized in that when the physical data indicating an abnormal value returns to a normal value, or when a predetermined period has elapsed since the abnormal value was indicated, the transmission cycle to the management server is returned to the first cycle. According to this configuration, Even if the transmission cycle to the management server becomes shorter, as long as a predetermined condition is satisfied, the measurement cycle returns to the normal cycle. Therefore, the amount of data communicated with the management server only temporarily increases, and the burden on the management server and the communication line can be minimized.

[0010] ​ The invention according to claim 5 is, in the configuration described in claim 2 , The physical data collected by the data collection means includes leakage current information of a specific part.

[0012] The invention according to claim 7 is, in the configuration described in claim 6 , The transmission control means measures the measurement cycle of the physical data of at least a specific device in the second cycle and transmits it to the management server when the contact signal received by the contact information collection means is an alarm signal indicating a leakage occurrence or an alarm signal indicating an insulation abnormality. The management server is characterized by having a function of early data analysis to determine where the cause of the received alarm signal indicating an abnormality lies. is set as According to this configuration, For example, when an insulation abnormality is detected, the measurement cycle of the physical data of a specific device becomes shorter. Therefore, for example, when a transformer shows an insulation abnormality, a large amount of physical data related to the transformer can be obtained, and because of the function of being able to early data analyze where the cause of the abnormal value lies, it becomes easier to investigate the cause. .

[0013] The invention according to claim 8 is, in the configuration described in claim Among any of 1 to 7 , It has a management terminal for accessing the management server and browsing the accumulated cubicle information. The management terminal can communicate with the cubicle internal management device via the management server, and can change the physical data transmission cycle from the cubicle internal management device to the management server by operating the management terminal. . According to this configuration, Since the acquisition cycle of the physical data can be changed by an external operation, the measurement cycle can be shortened even if an abnormal value is not detected, and it is easy to manage.

[0014] The invention according to claim 9 is, in the configuration described in claim 8 , The management server is characterized in that, when physical data indicating an abnormal value is transmitted, the management server notifies the management terminal of the physical data and information on the measurement site. .

The invention according to claim 10 is the configuration according to claim 8 or 9, wherein the in-cubicle management device has a threshold storage unit for determining an abnormal value, and thresholds are stored for each measurement site and each physical data. The determination unit determines the normality / abnormality of the physical data based on the threshold. On the other hand, from the management terminal, when the physical data of the data collection means approaches the threshold while being a normal value, it is possible to set a prediction threshold that can recognize this. The management server stores the prediction threshold set by the management server. The management server is characterized in that, when the physical data transmitted from the in-cubicle management device exceeds the prediction threshold, the management server transmits the information to the management terminal. . According to this configuration, if a prediction threshold is set, when physical data indicating a value close to the threshold occurs by operating the management terminal, the management terminal can recognize it. Therefore, the administrator can grasp the sign of the occurrence of an abnormality, and it is easy to manage the cubicle.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of a cubicle management system according to the present invention. The cubicle management system 1 includes a cubicle internal management device 2 installed inside the cubicle 10, a management server 3 arranged outside, a management terminal 4 operated by a manager, a weather server 5, and the like. The management server 3 is arranged on the cloud and is connected to the cubicle internal management device 2, the management terminal 4, and the weather server 5 via a communication network N.

[0018] FIG. 2 shows a block diagram of the cubicle internal management device 2. As shown in FIG. 2, the cubicle internal management device 2 includes a data collection device (data collection means) 21 for acquiring the state information of the cubicle 10, a contact information input device (contact information collection means) 21c, and a transmission control device (transmission control means) 22. The cubicle 10 houses high-voltage power receiving equipment. Specifically, it houses a transformer that converts the received high voltage to low voltage, a high-voltage AC load switch, a circuit breaker, a vacuum circuit breaker, a current-limiting fuse, a high-voltage phase-advancing capacitor, a wiring breaker, an instrument transformer, etc. (none of which are shown in the figure). The state information collected by the data collection device 21 is physical data such as the voltage and current of the electric circuit arranged between these devices and the temperature of the devices. The data collected by the contact information input device 21c is various contact information such as interruption information and alarm information. Specifically, the data collection device 21 includes a first measurement device 21a that collects physical data related to power, a second measurement device 21b that collects physical data related to temperature, and a contact information input device (contact information collection means) 21c that collects contact information within the cubicle 10.

[0019] The first measurement device 21a includes an input unit 51 for inputting measurement information, a first measurement device CPU 52 that controls the measurement and also serves as a determination unit for determining the normality / abnormality of the measurement values, a storage unit (threshold storage unit) 53 that stores thresholds for determining the normality / abnormality of individual measurement values, a communication unit 54 that communicates with the transmission control device 22, and so on.

The first measurement device CPU 52 controls the first measurement device 21a and also serves as a power factor calculation unit, calculating and outputting power and power factor. Also, when there is a measurement value exceeding the threshold, the first measurement device CPU 52 generates an abnormality occurrence signal and transmits it to the transmission control device 22.

[0020] The second measurement device 21b includes an input unit 56 for inputting temperature information, a second measurement device CPU 57 that controls the measurement and also serves as a determination unit for determining the normality / abnormality of the measurement values, a storage unit (threshold storage unit) 58 that stores thresholds for determining the normality / abnormality of individual measurement values, a communication unit 59 that communicates with the transmission control device 22, and so on. The input unit 56 is connected to a thermometer (not shown), and inputs the oil temperature information T1 of the transformer, the temperature information T2 inside the cubicle 10, etc. The second measurement device CPU 57 controls the second measurement device 21b, and generates and transmits an abnormality occurrence signal to the transmission control device 22 if a measured value exceeds a threshold value.

[0021] The contact information input device 21c includes an input unit 61 for inputting contact information, a contact information input device CPU 62 for converting the input information into predetermined identification data, a communication unit 63 for transmitting the contact information obtained by communicating with the transmission control device 22, and the like. The input unit 61 inputs contact information such as the interruption information S1 of the circuit breaker, the vacuum circuit breaker, and the wiring breaker, the fuse information S2 such as the fuse blowing information of the current-limiting fuse, and further the alarm signal S3 of the insulation monitoring device 6, the alarm signal S4 of the leakage fire alarm 7, etc. The contact information input device CPU 62 controls the contact information input device 21c, and when contact information is input, converts it into a signal readable by the transmission control device 22 and outputs it via the communication unit 63.

[0022] The transmission control device 22 includes a first communication IF 71 for communicating with the data collection device 21 and the contact information input device 21c, a storage unit 72 for storing the obtained data, a transmission control device CPU 73 for controlling the transmission control device 22, a second communication IF 74 for communicating with the management server 3, and the like. The transmission control device CPU 73 performs control to shorten the transmission cycle for transmitting data to the management server 3 for the first measurement device 21a or the second measurement device 21b that has transmitted an abnormal value, and to shorten the measurement cycle as necessary.

[0023] Figure 3 shows a block diagram of the management server 3. As shown in Figure 3, the management server 3 includes a data storage unit 31 that stores data transmitted from a plurality of cubicles 10 being managed, a management terminal information storage unit 32 that stores information (such as email address information) of the management terminal 4 associated with each cubicle 10, an area information storage unit 33 that stores the area (region) where the cubicle 10 is installed, a prediction threshold storage unit 34, a management server CPU 35 that controls the management server 3, a management server communication IF 36 that communicates with the in-cubicle management device 2 etc. via the communication network N, and so on. The prediction threshold storage unit 34 stores thresholds set by an administrator operating the management terminal 4 for the purpose described later.

[0024] Figure 4 shows a block diagram of the management terminal 4. As shown in Figure 4, the management terminal 4 has an operation unit 41, a display unit 42, a storage unit 43, a management terminal CPU 44, a communication unit 45, and so on. The management terminal 4 is a terminal operated by the administrator of the cubicle 10, and can access the management server 3 to obtain various data of a specific cubicle 10 stored in the management server 3. The obtained data can be displayed on the display unit 42 for viewing and saved in the storage unit 43. Also, by operating the operation unit 41, it is possible to communicate with the in-cubicle management device 2 via the management server 3 to change a specific operation of the in-cubicle management device 2. This management terminal 4 can use a personal computer, a tablet terminal, etc.

[0025] The weather server 5 is a data server managed by the Japan Meteorological Agency or a weather business operator etc. that provides weather information, and generally provides information such as the weather, temperature, wind direction, etc. for each area.

[0026] The cubicle management system 1 configured as described above operates as follows. First, the case where the measured physical data shows an abnormal value will be described. The transmission control device 22 collects data from the first measurement device 21a, the second measurement device 21b, and the contact information input device 21c at regular time intervals, for example, every 60 seconds. Based on the request of the transmission control device 22, the first measurement device 21a transmits voltage information M1, M3, current information M2, M4, leakage current information M5, calculated power information, and power factor information of a predetermined part. Also, the second measurement device 21b transmits oil temperature information T1 and temperature information T2 of a predetermined part. On the other hand, when the contact information input device 21c receives contact information such as cutoff information S1, fuse information S2, and alarm signals S3, S4, etc., it transmits them to the transmission control device 22. Note that the transmission of contact information may be performed upon receiving a request from the transmission control device 22.

[0027] The transmission control device 22 stores the data collected in this way in the storage unit 72 and transmits it to the management server 3 at intervals of, for example, 30 minutes (the first cycle). At this time, all the data accumulated in 30 minutes may be transmitted, or only the latest data may be transmitted. The transmitted data is stored in the data storage unit 31 of the management server 3.

[0028] However, the first measurement device CPU 52 of the first measurement device 21a and the second measurement device CPU 57 of the second measurement device 21b monitor whether the individual measurement values indicate abnormal values. The threshold values set for the individual measurement values are stored in the storage units 53 and 58. If a measurement value exceeding the threshold value occurs, information on the occurrence of an abnormality is notified to the transmission control device 22. This notification is also transmitted from the transmission control device 22 to the management server 3.

[0029] Upon receiving the notification of the occurrence of an abnormality, the transmission control device 22 shortens the transmission cycle of the measurement values from the data collection device 21 for the value determined to be an abnormal value to, for example, 5 minutes (the second cycle) and then transmits it.

[0030] Note that when changing the transmission cycle when an abnormal value is detected, not only for specific measurement values but also the transmission intervals of all measurement values may be shortened. Also, since the interval for collecting data from the data collection device 21 is 60 seconds here, this cycle is not changed. However, if the normal cycle for collecting data from the data collection device 21 is longer than the shortened transmission cycle to the management server 3, it is changed to the shorter cycle.

[0031] Upon receiving a notification of an abnormality, the management server 3 notifies a specific management terminal 4 of the occurrence of the abnormality. The management server 3 reads from the management terminal information storage unit 32 the management terminal 4 associated with the cubicle 10 where the abnormality occurred, and notifies it via e-mail or the like. For example, a message such as "Leakage current has been detected in the cubicle of ○○" is sent. In this way, since the management terminal 4 is notified when an abnormal value is detected, it is easy for the administrator to grasp the occurrence of an abnormality in the cubicle 10.

[0032] Here, the operation of the management server 3 when the leakage current information M5 indicates an abnormal value will be specifically described. If the leakage current information M5 indicates an abnormal value, the transmission control device 22 transmits the measurement data of the leakage current information M5 to the management server 3 at a short period as the second period. On the other hand, the management server 3 operates as follows. The management server 3 communicates with the weather server 5, obtains the weather information of the area where the cubicle 10 showing the leakage abnormality is located by the management server CPU 35 as the weather information acquisition unit, associates it with the measured leakage current data, and stores it in the data storage unit 31. Note that information for accessing the weather server 5, such as its address, is registered in advance in the management server 3.

[0033] FIG. 5 is an explanatory diagram for displaying a leakage analysis screen diagram on the display unit 42 of the management terminal 4, and is an explanatory diagram for displaying data associated with weather information upon receiving an alarm signal indicating a leakage abnormality. FIG. 5(a) is an explanatory diagram for selecting data, and FIG. 5(b) is an explanatory diagram for displaying the time change of the leakage current on the selected day. FIG. 6 is an explanatory diagram for displaying the time change of the leakage current in combination with the weather information on the management terminal 4. Note that this display shows data obtained by measuring the leakage current of each of the three transformers provided in the cubicle. In this way, since the leakage current information when indicating a leakage abnormality is stored together with the weather information, by selecting a due date on the management terminal 4, the change data of the leakage current can be obtained together with the weather information from the management server 3 and easily displayed, making it easier to investigate the cause.

[0034] Also, when detecting an abnormal power factor on the high-voltage side, it operates as follows. The first measuring device 21a monitors the power factors of a plurality of parts on the low-voltage side in addition to the power factor on the high-voltage side. When the power factor on the high-voltage side exceeds the threshold value and shows an abnormal value, under the control of the transmission control device 22, in addition to the power factor data on the high-voltage side, the acquisition period of at least the power factor data on the low-voltage side among other measured values is also shortened to the second period and transmitted to the management server 3. In this way, when the power factor on the high-voltage side deteriorates, in addition to the power factor on the high-voltage side, the acquisition periods of the power factor information of a plurality of parts on the low-voltage side also become shorter, making it easier to identify the cause.

[0035] After that, when the abnormal value detected in this way returns to the normal value after the administrator who recognized it takes countermeasures, the transmission control device CPU 73 recognizes it, and the data transmission period returns to the original period (the first period). Note that although control is implemented to return to the original first period when it returns to the normal value, in order to check the subsequent state, it may be returned to the first period after continuing a short transmission interval for a certain period such as one week. Also, even if the measurement data does not return to the normal value, control may be performed to return to the original period after, for example, 30 days have passed.

[0036] In this way, for at least the part where the physical data shows an abnormal value, since the period of measurement and transmission to the management server 3 is shortened, it is easier to investigate the cause. Also, even if the transmission period to the management server 3 becomes shorter, when a predetermined condition such as returning to the normal value is satisfied, the measurement period returns to the normal period. Therefore, the amount of data communicated with the management server 3 only temporarily increases, and the burden on the management server 3 and the communication line can be minimized.

[0037] Next, the case where contact information indicating an abnormality is input to the contact information input device 21c will be described. For example, when an alarm signal S3 indicating insulation abnormality is transmitted from the insulation monitoring device 6 to the contact information input device 21c, first, under the control of the contact information input device CPU 62, the detection location information is attached to the alarm signal S3 and transmitted to the transmission control device 22. Note that the installation location information of various devices that transmit contact signals is stored in the contact information input device CPU 62. In the transmission control device 22 that receives this alarm signal S3, the transmission control device CPU 73 first transmits the alarm signal S3 to the management server 3. After that, it identifies the device indicating insulation abnormality and obtains physical data such as its current information, and transmits it to the management server 3. For example, if it is contact information indicating insulation abnormality of a transformer, the current, voltage, temperature information, etc. of the transformer are obtained in the second period, and the data is transmitted to the management server 3.

[0038] In the management server 3, the transmitted data is stored in the data storage unit 31. Note that in this case as well, if it is set to obtain meteorological data as in the case of detecting leakage abnormality, the physical data of the part indicating insulation abnormality and the meteorological data can be stored together, and as shown in FIG. 6 above, the physical data obtained together with the meteorological information can be displayed on the management terminal 4, making it easier to quickly identify the cause when an abnormal value is shown. Note that here, the case of receiving the alarm signal S3 of insulation abnormality has been described, but the same applies when receiving the contact signal of leakage abnormality. Data storage can be carried out in combination with meteorological information, enabling early data analysis of where the cause of the abnormal value is.

[0039] In this way, when insulation abnormality or leakage abnormality is detected, the measurement period of the physical data of the device where the abnormality is detected becomes shorter. For example, if a transformer shows insulation abnormality, a large amount of physical data related to the transformer can be obtained, making it easier to identify the cause. Note that when the contact information indicating abnormality input to the contact information input device 21c is the alarm signal S4 of the leakage fire alarm 7, similarly, the current, voltage, temperature information, etc. of the device indicating leakage abnormality are obtained in the second period and transmitted to the management server 3.

[0040] In addition, the following operations can be performed by operating the management terminal 4. When the measured value of the data collection device 21 approaches the threshold value while being a normal value, a prediction threshold value that can recognize this can be set from the management terminal 4. The prediction threshold value set by operating the operation unit 41 is transmitted to the management server 3 and stored in the prediction threshold value storage unit 34. Upon receiving this setting, when the measured value transmitted from the cubicle internal management device 2 exceeds the set prediction threshold value under the control of the management server CPU 35, the management server 3 transmits the part information and the measured value to the management terminal 4.

[0041] In this way, if the prediction threshold value is set, when physical data indicating a value close to the threshold value is generated by operating the management terminal 4, the management terminal 4 can recognize it. Therefore, the administrator can grasp the sign of an abnormality occurring, and it is easy to manage the cubicle 10.

[0042] Furthermore, the measurement period of the data collection device 21 can be changed by operating the management terminal 4. Specifically, by a predetermined operation of the operation unit 41, access can be made to the cubicle internal management device 2 to be managed via the management server 3, and the measurement period of the data collection device 21 can be changed from the first period to the second period, or conversely from the second period to the first period. FIG. 7 shows an operation screen of the management terminal 4 for manually changing the data acquisition period when the measured value deviates from the threshold value. From such a screen, the acquisition periods of various data can be changed.

[0043] In this way, by making it possible to change the acquisition period of physical data by an external operation, the measurement period can be shortened even if an abnormal value is not detected, and when there is no problem even if an abnormal value is shown, it can be returned from the second period to the first period, enabling preferable management.

[0044] In the above embodiment, the transmission control device 22 communicates with the management server 3 via the communication network N. However, when there is an EMS for managing a storage battery in the cubicle 10, the external communication function of the EMS can be used to substitute the first communication IF 71 of the transmission control device 22 with the EMS and communicate with the management server 3 via the EMS. Furthermore, although the threshold value is provided in the data collection device 21 and the abnormality determination is performed by the data collection device 21, it may be determined collectively in the transmission control device 22. Also, the contact information input device 21c may not be provided, and only the data collection device 21 composed of the first measurement device 21a and the second measurement device 21b may be sufficient. Furthermore, although the data collection device 21 is composed of the first measurement device 21a and the second measurement device 21b, it is possible to perform useful cubicle management with only the first measurement device 21a.
