Description

The present invention relates to a system for determining abnormal operation of flashers and lighting equipment.

Lighting devices such as street lights and outdoor lights are connected to a power source (for example, a commercial power source) through flashers. In addition, the flasher is installed on an illuminance sensor that detects the surrounding environmental illuminance or on a power supply line that supplies power from a power source to a lighting fixture, and is also equipped with a switch (for example, switch circuits such as relays and transistors).

In the blinker having the above configuration, when the illuminance value detected by the illuminance sensor falls below a predetermined value during nighttime, the switch closes and current from the power source flows to the lighting fixture. This turns on the lighting fixture. On the other hand, during sunshine hours, when the illuminance value detected by the illuminance sensor exceeds a predetermined value, the switch opens and the current to the lighting fixture is cut off. This turns off the lighting fixture.

On the other hand, due to a malfunction of the flasher (illuminance sensor or switch) or a failure of the lighting equipment, the lighting equipment may be turned off even though it is night time (unlit state), or the lighting equipment may be turned off during the daylight hours. Abnormal operation may occur, such as the lighting equipment being turned on (daytime lighting state) despite the fact that the An invention capable of determining abnormal operation of such lighting equipment is disclosed in, for example, Patent Document 1 below.

Japanese Patent Application Publication No. 2020-177866

The flasher disclosed in Patent Document 1 includes an illuminance detection circuit (a circuit including an illuminance sensor), a switch circuit (a circuit including a relay switch), a current detection circuit that detects an input current supplied from an input power source, and the like. Further, the blinker disclosed in Patent Document 1 transmits detection data including an input current value (current data) detected by a current detection circuit to a server for lighting monitoring. Furthermore, the processing unit (processor) of the server determines detection abnormality of the illuminance detection circuit, abnormal operation of the switch circuit, etc. based on the received detection data.

However, in the invention disclosed in Patent Document 1, the current detection circuit is arranged closer to the input power source than the switch circuit. Therefore, the current data detected by the current detection circuit includes both the drive current of the flasher and the drive current of the lighting equipment. In other words, the current data detected by the current detection circuit is current data in which the drive current of the blinker and the drive current of the lighting fixture are superimposed, so that only the drive current of the lighting fixture cannot be accurately detected. Therefore, there is a possibility that abnormal operation of the lighting equipment cannot be accurately determined.

Furthermore, lighting equipment using LEDs as a light source consumes less power than mercury lamps and the like. From this, it is assumed that the driving current of the blinker becomes larger than the driving current of the lighting equipment. As a result, the possibility that abnormal operation of the lighting equipment cannot be accurately determined further increases.

In view of the above-mentioned problems, an object of the present invention is to provide a flasher that can accurately determine abnormal operation of a lighting equipment, and a system for determining abnormal operation of a lighting equipment.

[composition]
EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings, the abnormal operation determination system 1 (hereinafter, "abnormal operation determination system 1") for a lighting fixture according to one embodiment of the present invention will be described in detail. First, with reference to FIGS. 1 to 3, the abnormal operation determination system 1 and the flasher 2 and server 4 that constitute the abnormal operation determination system 1 will be described.

Here, FIG. 1 is a block diagram showing the configuration of an abnormal operation determination system 1 according to the present embodiment. Moreover, FIG. 2 is a functional block diagram of the blinker 2 of this embodiment. Furthermore, FIG. 3 is a functional block diagram of the server 4 of this embodiment.

As shown in FIG. 1, the abnormal operation determination system 1 includes a blinker 2, a lighting fixture 3 (for example, a street light, an outdoor light, etc.) equipped with a light source such as an LED, a server 4, an administrator terminal 5 (for example, (including personal computers, smartphones, tablets, etc.). Further, the blinker 2, the server 4, and the administrator terminal 5 are connected via a communication line 6.

Furthermore, it is preferable that the abnormal operation determination system 1 according to the present embodiment includes an environmental sensor 7 connected to, for example, the flasher 2 or the like. Note that examples of data that can be detected by the environmental sensor 7 include data such as temperature and humidity data, solar radiation data, water level data, rainfall data, wind speed data, snowfall data, and vibration data in the environment surrounding the flasher 2. However, it is not limited to this. By providing the environmental sensor 7, it is also possible to monitor the infrastructure of the pole on which the lighting fixture 3 is erected and surrounding structures.

Further, the blinker 2 and the lighting fixture 3 are connected, for example, via a power supply line 21 (see FIG. 2) extending from a commercial power source 8. Thereby, the flasher 2 is electrically connected to the lighting fixture 3 and can control the lighting state/unlighting state of the lighting fixture 3. In addition, in FIG. 1, although the number of lighting fixtures 3 connected to the flasher 2 is one, a plurality of lighting fixtures 3 may be connected to the flasher 2.

Next, as shown in FIG. 2, the blinker 2 is interposed between a power source 8 (for example, a commercial power source) and the lighting fixture 3, and is used to control the lighting/extinguishing state of the lighting fixture 3. equipment. As described above, the blinker 2 is connected to the power source 8 and the lighting fixture 3 via the power supply line 21.

Here, the blinker 2 includes an illuminance sensor 22 (for example, a sensor circuit including a photodiode, etc.), a switch 23 provided on the power supply line 21 (for example, a switch circuit including a relay switch, a transistor, etc.), and a current flowing through the power supply line 21. It includes a current sensor 24 that detects a current value (current data), a lighting/unlighting identification section 25 that identifies the lighting/unlighting state of the lighting fixture 3, a communication section 26 (communication interface) that communicates with the server 4, etc.

Furthermore, it is preferable that the blinker 2 includes a positioning unit (for example, GPS, etc.), which is not shown. Based on the position information of the blinker 2 that has been positioned, the installation location of the lighting abnormality can be identified, making it easier to deal with the abnormality.

The illuminance sensor 22 in this embodiment detects the surrounding illuminance value (received light intensity), and when the detected illuminance value is lower than a predetermined threshold (nighttime), a signal (high level signal) for closing the switch is sent to the switch. Send to 23. As a result, the switch 23 that has received the high level signal closes, and current from the power source 8 flows to the lighting fixture 3. As a result, the lighting fixture 3 lights up.

On the other hand, when the detected illuminance value exceeds a predetermined threshold (during sunshine hours), the illuminance sensor 22 transmits a signal (low level signal) for opening the switch to the switch 23. As a result, the switch 23 that has received the low level signal opens, and the current that has been flowing to the lighting fixture 3 side is cut off. As a result, the lighting fixture 3 is turned off.

Next, the current sensor 24 detects current data flowing through the power supply line 21 during a predetermined period including the nighttime period and the sunshine period. As shown in FIG. 2, the current sensor 24 of this embodiment detects current data flowing through a portion of the power supply line 21 closer to the lighting fixture 3 than the switch 23 (power supply line portion). Further, the current sensor 24 of this embodiment transmits the detected current data to the lighting/lighting out identification section 25.

Next, the lighting/lighting out identification unit 25 identifies whether the lighting fixture 3 is in a lighting state or a lighting out state based on the current data acquired from the current sensor 24.

Further, the lighting/lights-off identification unit 25 transmits, for example, identification information (identification data) for lighting/lighting out of the lighting fixture 3 to the server 4 via the communication unit 26 (the communication unit 26 of the blinker 2 function as a data transmitter, etc.).

As described above, the communication unit 26 of the blinker 2 may transmit and receive data other than the identification data for turning on/off the lighting fixture 3. Examples of other data include illuminance data obtained by the illuminance sensor 22, sunrise/sunset time data, and the like. However, it is not limited to this.

Here, the lighting/lighting out identification unit 25 uses data on the current flowing from the switch 23 to the power supply line portion on the lighting equipment 3 side when identifying the lighting/lighting out state of the lighting equipment 3. In other words, the lighting/lighting out identification unit 25 identifies lighting/lighting out of the lighting fixture 3 based on the driving current of the lighting fixture 3. Thereby, identification data for accurately determining abnormal operation of the lighting fixture 3 can be provided (generated).

Furthermore, the flasher 2 may calculate the current detection time (time) using a timer built in the arithmetic processing unit (CPU). Further, it is preferable that the obtained detection time data is transmitted to the server 4 via the communication unit 26 together with the identification data generated by the lighting/lights-off identification unit 25.

Next, the server 4 will be explained with reference to FIG. As shown in FIG. 3, the server 4 of this embodiment includes a data receiving section 41, a daytime lighting/non-lighting determining section 42, a data transmitting section 43, a received data storage section 44, a latest state data storage section 45, and a user data storage section 45. It includes a storage unit 46 and the like. Specifically, for example, the communication interface of the server 4 serves as the data receiving section 41 and the data transmitting section 43. Further, the arithmetic processing unit (CPU) and storage unit (ROM or hard disk) of the server 4 serve as the daytime lighting/non-lighting determination unit 42 . Further, the storage unit (hard disk) of the server 4 serves as a received data storage unit 44 and a user data storage unit 45. Note that the received data storage section 44, the latest state data storage section 45, and the user data storage section 46 may be constructed in a relational database format in which they are associated with each other.

The data receiving unit 41 receives identification data, detection time data, etc. transmitted from the flasher 2. That is, the data receiving section 41 of this embodiment functions as, for example, an identification data receiving section. Further, the daytime lighting/non-lighting determining unit 42 determines the daytime lighting/non-lighting state of the lighting fixture 3 based on the received identification data and detection time data. The daytime lighting/non-lighting determining unit 42 determines whether the lighting fixture 3 is operating abnormally.

Here, the "daytime lighting state" refers to a state in which the lighting fixture 3 is turned on during a time period when it should not be turned on (sunshine time period). In addition, the "unlit state" refers to a state in which the lighting fixture 3 is not lit during the time period (nighttime period) when it should be lit.

The manner in which the daytime lighting/non-lighting state of the lighting fixture 3 is determined is not particularly limited, but as an example, the server 4 may use current data continuously detected by the current sensor 24 during a predetermined period. An example of an embodiment is to receive the identified identification data (on/off state of the lighting fixture 3) from the flasher 2, and determine whether the lighting fixture is on or off during the day from the received identification data.

In addition, as another example, the server 4 stores each identification data (preferably a detection time associated with each identification data) that identifies the lighting/unlighting state of the lighting fixture 3 based on current data detected multiple times in a predetermined period. data) is received from the blinker 2, and among the received identification data, the number of first identification data (identification data indicating that the lighting fixture 3 is in the lighting state) and the number of second identification data (identification data that the lighting fixture 3 is in the lighting state) The daytime lighting/non-lighting state of the lighting fixture 3 may be determined based on at least one of the number of identification data (identification data indicating that the lighting equipment 3 is present).

More specifically, for example, the current of the power supply line 21 is measured every two hours using the current sensor 24 from 0:00 on January 1, 2022 to 0:00 on January 2, 2022. When detecting, 12 pieces of current data are obtained. Furthermore, 12 pieces of identification data are obtained from the 12 pieces of detected current data (each piece of identification data includes information for identifying the on/off state of the lighting fixture 3 at the time of each current detection).

The server 4 (daytime lighting/non-lighting determining unit 42) that receives such a plurality of identification data from the blinker 2 counts the number of first identification data and second identification data, and counts the number of first identification data and second identification data, for example, 12 pieces of identification data. Among them, when the first identification data exceeds eight (threshold) (in the case of nine or more), it is determined that the lighting fixture 3 is in the daytime lighting state. Alternatively, when the second identification data exceeds eight (threshold) (in the case of nine or more), it is determined that the lighting fixture 3 is in the non-lighting state. Further, the determined state of the lighting fixture 3 is stored in the latest state data storage section 45. However, the mode of determination by the daytime lighting/non-lighting determining section 42 is not limited to this.

According to this aspect, the lighting/unlighting state of the lighting fixture 3 is identified from each current data detected a plurality of times in a predetermined period, and the number of first identification data and second identification data among the obtained identification data are identified. The daytime lighting/non-lighting state of the lighting fixture 3 is determined based on at least one of the numbers of identification data. Therefore, the calculation cost of the server 4 can be reduced, for example, compared to a mode in which abnormal operation of the lighting fixture 3 is determined from constantly detected current data. Furthermore, since the amount of first identification data and second identification data that only indicate the lighting/extinguishing state is smaller than the amount of data indicating the detected current data, the data amount of the first identification data and second identification data, which only indicate the lighting/extinguishing state, is not transmitted from the flasher 2 to the server 4. The amount of communication data and number of communications can be reduced.

Next, the data transmitting unit 43 refers to the latest status data storage unit 45 and the user data storage unit 46 and sends monitoring data including the determined daytime lighting/non-lighting state of the lighting fixture 3 to the administrator terminal 5. Send. Thereby, the administrator can grasp the latest status of the lighting equipment 3.

Further, the server 4 may further include an integrated lighting time calculation section 47. Specifically, the integrated lighting time calculation unit 47 counts the number of first identification data from a plurality of identification data obtained from each current data detected multiple times at a predetermined period, received from the flasher 2. , the cumulative lighting time of the lighting fixture 3 is calculated from the number of first identification data and the predetermined period.

For example, if 100 pieces of first identification data (identification data indicating that the lighting fixture 3 is in the lighting state) are obtained from the current of the power supply line 21 detected every two hours by the current sensor 24, the cumulative lighting time calculation unit 47 calculates the cumulative lighting time of the lighting equipment 3 as 100 pieces (number of first identification data) x 2 hours (cycle of current detection) = 200 hours.

By providing the cumulative lighting time calculation unit 47 in this manner, the cost for calculating the cumulative lighting time of the lighting equipment 3 in the server 4 can be reduced. Further, by calculating the cumulative lighting time of the lighting fixture 3, an index related to the lifespan of the lighting fixture 3 can be obtained. Note that the cumulative lighting time calculation unit 47 of this embodiment is handled by the arithmetic processing unit (CPU) and storage unit (ROM or hard disk) of the server 4.

Next, with reference to FIG. 4, the operation of the abnormal operation determination system 1 according to this embodiment will be explained. Here, FIG. 4 is a flowchart showing the operation of the abnormal operation determination system 1.

First, at a predetermined time point, the current sensor 24 of the blinker 2 detects the current on the lighting fixture 3 side from the switch 23 in the power supply line 21 (S1). Further, the current sensor 24 transmits the detected current data and detection time data to the on/off identification section 25 of the flasher 2 .

Subsequently, the lighting/lighting out identification unit 25 refers to the received current data and detection time data to identify the lighting/lighting out state of the lighting fixture 3 (S2). Further, the lighting/lighting out identification unit 25 transmits identification data including identification information of the lighting/lighting out state of the lighting fixture 3 to the server 4 via the communication unit 26 of the flasher 2 (S3).

Next, the server 4 (daytime lighting/non-lighting determination unit 42) determines whether or not the lighting fixture 3 is exhibiting an abnormal operation (daytime lighting/non-lighting state) based on the received identification data (S4). . Further, the server 4 accesses the latest state data storage unit 45 and stores information about the lighting fixture 3 stored in the latest state data storage unit 45 so as to reflect the determined daytime lighting/non-lighting state of the lighting fixture 3. Update.

Furthermore, the server 4 refers to the latest status data storage unit 45 and user data storage unit 46 and transmits monitoring data including information such as the determined daytime lighting/non-lighting state of the lighting fixture 3 to the administrator terminal 5. (S5).

The embodiments according to the present invention have been described above in detail. However, the above description is provided to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention may include modifications and improvements that may be made without departing from the spirit thereof. The present invention also includes equivalents thereof.

For example, in the embodiment described above, the lighting/unlighting state of the lighting fixture 3 is identified on the blinker 2 side, but this may be performed on the server 4 side. That is, the server 4 includes a lighting/unlighting identification section that identifies the lighting/unlighting state of the lighting fixture 3 and generates identification data. At this time, the blinker 2 transmits the current data detected by the current sensor 24 to the server 4, and the server 4 identifies the on/off state of the lighting fixture 3 from the received current data, etc. It is determined whether the appliance 3 is lit during the day or not lit.

In addition, in this aspect, the communication section 26 of the blinker 2 functions as a current data transmitting section and the like. Further, the data receiving section 41 of the server 4 functions as a current data receiving section and the like.

On the other hand, in addition to detecting current data and identifying whether the lighting fixture 3 is on or off, the flasher 2 may also determine whether the lighting fixture 3 is on or off during the day. In this case, the flasher 2 may transmit the determination result to the server 4 or the administrator terminal 5.
