  As a method of inspecting whether or not the aviation obstacle light installed in the power transmission tower is normally lit, there are the following techniques in addition to the method of performing regular patrol.

  For example, Japanese Patent Laid-Open No. 2003-45682 discloses an easy-to-use aviation obstacle light that can be easily added to an aviation obstacle light system that uses electric lamps, lamps, etc., and that can detect disconnection without being restricted by location. A disconnection detection system is disclosed. Specifically, waveform measurement data such as a current signal supplied to a low-light failure lamp with a lighting operation and a medium-light failure lamp with a blinking operation is measured, and an offset component of the waveform measurement data is used to calculate the low-light failure lamp. The disconnection is detected from the pulsating flow component of the waveform measurement data, and the disconnection of the medium light intensity trouble lamp is detected, and the disconnection information is reported to the facsimile apparatus via the transmission device. However, this publication does not consider the type of aviation obstacle light.

Japanese Patent Application Laid-Open No. 2004-117223 discloses a monitoring system that can constantly monitor abnormal information that occurs in a power transportation facility with low occurrence frequency at a comprehensively low running cost. Specifically, at least two or more types of abnormal information such as lightning strike information, accident information, accident section information, aviation obstacle light information, or intruder information, which are infrequently generated in the power transmission line or the surrounding power transportation facilities, are constantly monitored. It can be a comprehensive monitoring system. Each power transmission tower or its surroundings has a detection unit that can detect and detect each abnormality information by the presence or absence of abnormality, and is connected to the detection unit so as to be detachable, and together with the detected abnormality information, it is located in a remote area for monitoring purposes. A large number of monitoring transmission devices including an information transmission unit that transmits the information to the destination are provided. The abnormality information detected by each detection unit is transmitted to a remote area with an identification code for identifying itself together with the abnormality information detected from each information transmission unit connected to each detection unit. However, this publication does not disclose how to specifically detect the disconnection of an aviation obstacle light.

  In the case of adopting a method for detecting stigmatization of aviation obstacle lights by patrol, introduction cost and running cost become a big problem to introduce a device for detecting stigma of aviation obstacle lights. Currently, low-luminance aviation obstruction lights include light bulb-type aviation obstruction lights (OM-3A) and neon tube-type aviation obstruction lights (OM-3B). Cost cannot be reduced. Further, although there is a power failure in addition to the disconnection / disconnection, the introduction cost and the running cost must be reduced when dealing with the power failure.

  Accordingly, an object of the present invention is to provide an aviation obstacle light state notification device that enables cost reduction.

  Another object of the present invention is to provide an aviation obstruction light status notification device that can cope with the disadvantages of different types of aviation obstruction lights.

  The aviation obstacle light state notification device according to the present invention has a notification means for notifying a predetermined notification destination of the occurrence of a power failure of an aviation obstacle light, and a capacity capable of storing electric power necessary for at least one notification. And a capacitor that charges when the aviation obstacle light is energized, discharges when the aviation obstacle light fails, and supplies power to the notification means. In this way, since the minimum necessary notification can be performed at the time of a power failure without using a battery that requires maintenance, the aviation obstacle light state notification device is introduced at a low cost including the running cost. Will be able to.

  The present invention may further include a calculation unit that calculates the active power by measuring waveforms of current and voltage supplied to the aviation obstacle light, and a comparison unit that compares the active power with a threshold value. Good. Then, when the notification means described above has a predetermined relationship between the active power and the threshold, a state corresponding to the predetermined relationship may be notified to a predetermined notification destination. By calculating the active power in this way, the state of the aviation obstruction light (for example, one lamp is unsatisfactory, etc.) regardless of whether it is a light bulb type aviation obstruction light or a neon tube type aviation obstruction light as described above. ) Can be properly detected. In addition, since it is not necessary to introduce a special sensor for detecting defects, the cost can be reduced.

  Furthermore, the calculation means described above may detect a power failure based on the waveform of the voltage supplied to the aviation obstacle light, and cause the notification means to notify the occurrence of the power failure. In this way, it is not necessary to introduce a device for detecting a power failure, and the cost can be reduced.

  The capacitor described above may be an electric double layer capacitor.

  Furthermore, in the present invention, a charging power supply circuit for charging the capacitor, a backup power supply circuit for supplying power from the capacitor to the notification means in the event of a power failure of the aviation obstacle light, and power to the notification means and necessary circuits when energized You may make it further have a normal power supply circuit which supplies. Such a simple configuration can cope with a power failure without using a battery.

  According to the present invention, it is possible to introduce an aviation obstacle light state notification device that enables cost reduction.

  Further, according to another aspect of the present invention, it is possible to cope with the disadvantages of different types of aviation obstacle lights.

[Assumptions of the embodiment]
FIG. 1 shows a measurement result when a light bulb type (OM-3A) aviation obstacle light is broken in a measurement circuit simulating a circuit of a low-luminance aviation obstacle light currently used. In FIG. 1, when the power supply voltage is 95V, 100V and 107V, and the aviation obstruction lights are from 0 light (all disconnected) to 4 lights (all lit), effective voltage (V), effective current (A ), The result of measuring the active power (W) and the power factor. FIG. 2 is a bar graph of the active power data in FIG. 1 and a line graph of the effective current (hereinafter sometimes referred to as current). In FIG. 2, the horizontal axis represents the number of lighting. Thus, in the light bulb type aviation obstacle light, the power factor is 1.00 regardless of the power supply voltage and the number of broken cores, and the current decreases in proportion to the increased number of broken aviation obstacle lights. Therefore, it can be seen that the active power also decreases in proportion to the increase in the number of broken aviation obstacle lights. The active power increases or decreases depending on the power supply voltage.

  On the other hand, the measurement result when the bulb of the neon tube type (OM-3B) aviation obstacle light is blown out in the same measurement circuit is shown in FIG. The results are shown in FIG. 3B. 3A and 3B are the same as those in FIG. 1 when the power supply voltage is 95V, 100V and 107V, and the aviation obstruction light is from 0 light (all off or broken) to 4 lights (all lit). , Effective voltage (V), effective current (A), active power (W), and power factor measurement results. FIG. 4 is a graph in which the active power data in FIGS. 3A and 3B is converted into a bar graph and the current is converted into a line graph. In FIG. 4, the horizontal axis represents the number of lighting. Unlike FIG. 1 and FIG. 2, in FIG. 3A representing the ball breakage, the power factor varies depending on the ball breakage number and the power supply voltage, and the current once decreases as the ball breakage number increases. It can be seen that the lighting state cannot be determined simply by the current or power factor, such as increasing the number of ball breaks at 3 and 4. However, the effective power decreases in proportion as the number of ball breaks increases. On the other hand, in FIG. 3B showing the disconnection, the power factor depends only on the power supply voltage, and the current decreases in proportion to the increase in the number of disconnections. Further, the active power decreases as the number of disconnections increases, as in FIGS. 1 and 3A.

  According to the inventor's new knowledge, only power factor and current are detected in order to cope with both the disconnection of a bulb-type aviation obstacle light and the breakage and disconnection of a neon tube-type aviation obstacle light. Therefore, it is difficult to accurately grasp the lighting state, and it is necessary to calculate the effective power and grasp the lighting state based on the effective power. Hereinafter, embodiments of the present invention based on such knowledge will be described in detail.

[Details of the embodiment of the present invention]
FIG. 5 shows a schematic diagram of the entire aviation obstacle light unnotification system. In the case of low light intensity, four aviation obstacle lights 3a to 3d are installed on the transmission tower 7. Conventionally, power is supplied directly from the existing distribution board 5 to the aviation obstacle lights 3a to 3d. In the present embodiment, the state notification device 1 is connected between the existing distribution board 5 and the aviation obstacle lights 3a to 3d. The status notification device 1 includes a wireless communication module, which will be described below, and performs wireless communication with the wireless base station 9 connected to the mobile phone network 11 for packet communication. The mobile phone network 11 is connected to an administrator terminal 15 or a mobile phone 13 of an administrator who manages the aviation obstacle lights 3a to 3d by wire or wireless.

  When the state notification device 1 detects an incongruity of an aviation obstacle light, a power failure, or the like, the state notification device 1 notifies the manager terminal 15 or the mobile phone 13 by e-mail via the radio base station 9 and the mobile phone network 11. Further, when an email including necessary data is transmitted from the administrator terminal 15 or the mobile phone 13 to the status notification device 1, the status notification device 1 can be inquired and set.

  Next, the configuration of the state notification device 1 will be described with reference to FIG. The state notification device 1 supplies power to the state notification device 1 including the CT (current transformer) that detects the current supplied to the aviation obstacle lights 3a to 3d, and supplies the aviation obstacle lights 3a to 3d. A power supply unit 115 that outputs a waveform of the supplied voltage to the processing unit 112, a processing unit 112 that includes a memory and that performs necessary arithmetic processing and control processing in the state notification device 1, and wireless communication for performing wireless communication The communication module 114 includes a transmission unit 113 that controls the wireless communication module 114 in accordance with an instruction from the processing unit 112, and an electric double layer capacitor 116 that performs charging for a normal period and discharges for a certain period during a power failure.

  The sensor unit 111 is connected to a distribution line from the existing distribution board 5 to the aviation obstacle lights 3a to 3d, and the current waveform measured by the sensor unit 111 is output to the processing unit 112. Similarly, the power supply unit 115 is connected to the distribution line from the existing distribution board 5 to the aviation obstacle lights 3a to 3d, and is further connected to the processing unit 112, the transmission unit 113, and the wireless communication module 114. In addition, the power supply unit 115 measures the voltage waveform of the supply voltage using, for example, an insulating transformer, and outputs the voltage waveform to the processing unit 112. A detailed configuration of the power supply unit 115 will be described later. The processing unit 112 performs processing described below, and outputs a notification instruction to the transmission unit 113 when notification is made by mail. In addition, the processing unit 112 may receive data or a request from the transmission unit 113 and perform processing. Note that the processing unit 112 stores sampling values of current and voltage for a predetermined memory capacity and uses them for calculations and the like. The transmission unit 113 controls the wireless communication module 114 according to the processing unit 112, and outputs necessary data or a request to the processing unit 112 when a mail is received via the wireless communication module 114. The wireless communication module 114 is an existing module that communicates with the wireless base station 9 connected to the mobile phone network 11.

  In addition, although the digitally sampled voltage waveform and current waveform are handled, sampling may be performed in the sensor unit 111 and the power supply unit 115 or may be performed in the processing unit 112.

  Next, basic processing contents of the state notification device 1 will be described with reference to FIG. The processing unit 112 refers to the voltage waveform from the power supply unit 115 to determine whether power is supplied to the aviation obstacle lights 3a to 3d (step S1). That is, it is determined whether the voltage is 0 or near 0 during a predetermined sampling period. When there is no voltage, that is, when it is determined that the voltage is 0 or close to 0 during the predetermined sampling period, the processing unit 112 is continuing the power failure by determining, for example, whether the power failure flag is set on. It is determined whether it exists (step S3). For example, if the power failure flag is set on and the power failure is continuing, the process returns to step S1.

  On the other hand, for example, when the power failure flag is set to OFF, the processing unit 112 performs a power failure occurrence process (step S5). Specifically, the processing unit 112 sets the power failure flag to ON, and further outputs an instruction to cause the transmission unit 113 to transmit the power failure occurrence notification mail to the wireless communication module 114. The transmission unit 113 and the wireless communication module 114 transmit a power failure occurrence notification mail to the administrator. The power failure notification email will be described later. Then, the process returns to step S1.

  When it is determined in step S1 that there is a voltage, the processing unit 112 determines whether the power failure has been restored (step S7). For example, it is determined whether or not a voltage greater than or equal to a predetermined value for a predetermined sampling period or more is detected in a state where the power failure flag is on. When it is determined that the power failure has been recovered, the processing unit 112 performs a power failure recovery process (step S9). Specifically, the processing unit 112 sets the power failure flag to OFF, and further outputs an instruction to cause the wireless communication module 114 to transmit a power failure recovery notification mail to the transmission unit 113. The transmission unit 113 and the wireless communication module 114 transmit a power failure recovery notification mail to the administrator. The power failure recovery notification email will be described later. Then, the process proceeds to step S11.

  When it is determined in step S7 that the power failure is not restored or after step S9, the processing unit 112 refers to the current waveform from the sensor unit 111 and determines whether a lamp current is detected (step S11). That is, it is determined whether the current value is 0 or close to 0 during a predetermined sampling period. When the lamp current is not detected, the processing unit 112 refers to the time of its own clock and determines whether the current time is a predetermined night (for example, from 20:00 to 4) (step S13). In the present embodiment, a control panel (not shown) is provided near the aviation obstacle lights 3a to 3d, and lighting of the aviation obstacle lights 3a to 3d is controlled only at night by the control panel. Therefore, since the lamp current does not flow through the aviation obstacle lights 3a to 3d unless it is nighttime, the process returns to step S1. On the other hand, at night, the processing unit 112 determines whether the control panel abnormality continues (step S15). For example, it is determined whether the control panel abnormality flag of the control panel (not shown) described above is set to ON. If it is determined that the control panel abnormality continues, the process returns to step S1.

  If the control panel abnormality is not continuing, the processing unit 112 performs a control panel abnormality process (step S17). Specifically, the processing unit 112 sets, for example, a control panel abnormality flag to ON, and outputs an instruction to cause the transmission unit 113 to transmit a control panel abnormality occurrence notification mail to the wireless communication module 114. The transmission unit 113 and the wireless communication module 114 transmit a control panel abnormality occurrence mail to the administrator. Then, the process returns to step S1.

  On the other hand, when it is determined in step S11 that there is a lamp current, the processing unit 112 determines whether the control panel abnormality is recovered (step S19). For example, it is determined whether the control panel abnormality flag is on and the lamp current is detected. If it is determined that the control panel abnormality has been recovered, the processing unit 112 performs a control panel abnormality recovery process (step S21). Specifically, for example, the control panel abnormality flag is set to OFF, and an instruction is sent to the transmission unit 113 to cause the wireless communication module 114 to transmit a control panel abnormality recovery notification mail. The transmission unit 113 and the wireless communication module 114 transmit a control panel abnormality recovery notification mail to the administrator. Then, the process proceeds to step S23.

When it is determined in step S19 that the control panel abnormality is not restored, or after step S21, the processing unit 112 calculates active power or the like (step S23). The active power P is calculated by the following formula.

  T is one period (for example, 20 ms), Δt is a sampling period (for example, 0.4 ms), e (k) is an instantaneous voltage, and i (k) is an instantaneous current. In step S23, an effective voltage and an effective current are calculated. Further, the power factor is also calculated by, for example, effective power / effective voltage * effective current. As for the data calculated in step S23, the latest data is preferentially held by a predetermined capacity in the memory of the processing unit 112.

  For example, when the aviation obstacle lights 3a to 3d are bulb-type aviation obstacle lights (for example, OM-3A), current and voltage waveforms as shown in FIGS. 8 to 11 are measured. 8 shows the case of full lighting, FIG. 9 shows the case of lighting of three lights, FIG. 10 shows the case of lighting of two lights, and FIG. 11 shows the case of lighting of one light. In both cases, the phases of the current and the voltage are almost the same, and the number of lightings decreases from FIG. 8 to FIG. 11, but the current value also decreases accordingly.

  In addition, FIG. 12 and FIG. 13 summarize the results of calculations based on the measurement results. As in FIG. 1, when the power supply voltage is 95V, 100V and 107V, and the aviation obstruction lights are 0 light (all disconnected) to 4 lights (all lit), effective voltage (V), effective current (A), active power (W) and power factor are shown. FIG. 13 is a graph in which the active power data in FIG. 12 is converted into a bar graph and the current is converted into a line graph. In FIG. 13, the horizontal axis represents the number of lighting. As described above, in the light bulb type aviation obstacle light, the power factor is almost 1.00 regardless of the power supply voltage and the number of breaks (excluding the breakage number 4), and the current is broken. The active power also decreases in proportion to the increase in the number of broken aviation obstacle lights. The active power increases or decreases depending on the power supply voltage.

  When the aviation obstacle lights 3a to 3d are neon tube type aviation obstacle lights (for example, OM-3B), current and voltage waveforms as shown in FIGS. 14 to 21 are measured. FIG. 14 shows the case of full lighting, FIG. 15 shows the case of three lighting with one light bulb, FIG. 16 shows the case with two lighting and two lighting balls, and FIG. 18 represents the case of 0 lamps lit 4 lamps, FIG. 19 represents the case of 3 lamps lit 1 lamp break, FIG. 20 represents the case of 2 lights lit 2 lamp breaks, 21 represents a case where one lamp is lit and three lamps are disconnected. In either case, the current and voltage waveforms are not in phase, and the power factor is less than 1.

  In addition, FIGS. 22 to 24 summarize the results of calculations based on the measurement results. Similar to FIG. 3A, FIG. 22 shows the case where the power supply voltage is 95V, 100V and 107V, and the effective voltage (V ), Effective current (A), active power (W), and power factor. Similarly to FIG. 3B, FIG. 23 shows the case where the power supply voltage is 95V, 100V and 107V, and the effective voltage (V) when the aviation obstruction lights are from 0 (all disconnected) to 4 (all lit). ), Effective current (A), active power (W), and power factor.

  FIG. 24 is a bar graph of the active power data of FIGS. 22 and 23 and a current graph of the current, as in FIGS. 3A and 3B. In FIG. 24, the horizontal axis represents the number of lighting. As described with reference to FIG. 4, in FIG. 22 representing the ball breakage, the power factor varies depending on the ball breakage and the power supply voltage, and the current also decreases once as the ball breakage number increases, but the number of ball breaks is reduced. It can be seen that the lighting state cannot be determined simply by the current or power factor, such as increasing at 3 and 4. However, the effective power decreases as the number of balls increases. On the other hand, in FIG. 23 representing the disconnection, the power factor depends only on the power supply voltage, and the current decreases in proportion to the increase in the number of disconnections. Further, the effective power decreases in proportion to the increase in the number of disconnections.

  As described above, measurement and calculation results similar to the premise of the present embodiment can be obtained. Accordingly, the threshold value for determining the incongruity is obtained as shown in FIG. 25 in the case of a light bulb type aviation obstacle light. That is, a value obtained by subtracting (effective power per lamp) / 2 from the effective power when the four lights are lit is specified as the threshold value. An intermediate value between the effective power when the four lights are lit and the effective power when the three lights are lit may be set as the threshold value. Whether the light bulb type or the neon tube type described below is determined is determined by whether or not there is a phase shift between the current waveform and the voltage waveform. You may judge with a power factor. Then, the value of active power serving as a threshold for each power supply voltage (effective voltage) is stored in the memory of the processing unit 112 in advance, and this time based on the phase shift in the current and voltage waveforms and the measurement or calculation result of the effective voltage. Specify the threshold to be applied.

  Further, in the case of a neon tube type aviation obstacle light, as shown in FIG. 26, a threshold value that clearly separates a broken ball and a broken wire cannot be set easily, so the threshold value is set based on the broken ball. . That is, as shown in FIG. 27, an intermediate value between the effective power when four lamps are lit and the effective power when three lamps are lit (one lamp is out) is specified as a threshold value. Then, the value of active power serving as a threshold for each power supply voltage (effective voltage) is stored in the memory of the processing unit 112 in advance, and this time based on the phase shift in the current and voltage waveforms and the measurement or calculation result of the effective voltage. Specify the threshold to be applied.

  As shown in FIG. 28, it can be seen that sufficient judgment can be made even if the threshold value set for the ball breakage of the neon tube type aircraft obstacle light is applied to the case of disconnection.

  In FIGS. 25 to 28, the threshold value to be detected when one lamp is unsatisfactory when four lamps are lit is described. However, if there is data as shown in FIGS. The threshold value, the threshold value in the case of three lamps being unsatisfactory, and the threshold value in the case of four lamps being unsatisfactory can be set in advance, and if stored in the memory of the processing unit 112, they are calculated in step S23. By determining which range the active power falls in, it is possible to specify the state of the aviation obstacle light such as the number of unsatisfactory or the number of lighting.

  Returning to the description of FIG. 7, the processing unit 112 specifies a threshold to be used this time among the thresholds stored in the memory from the effective voltage of the power supply voltage and the presence or absence of a phase shift of the waveform of the current and the voltage (step) S25). When simply determining the presence or absence of a failure, only the threshold value for determining the failure of one lamp is specified, and when specifying the number of failure points, all the relevant threshold values are specified.

  Then, the processing unit 112 determines whether or not the active power is within the normal range by comparing the active power calculated in step S23 with the threshold value specified in step S25 (step S27). Here, it is assumed that one lamp is unsatisfactory. Accordingly, when it is determined that the current value is not within the normal range, it is determined whether the disconnection / disconnection is continuing (step S29). For example, it is determined whether the disconnection / disconnection flag is set on. When it is determined that the disconnection / disconnection is continuing, the process returns to step S1. On the other hand, when it is determined that the disconnection / disconnection is not continuing, the processing unit 112 performs a process upon occurrence of disconnection / disconnection (step S31). Specifically, the processing unit 112 sets, for example, a disconnection / disconnection flag to ON, and outputs an instruction to the transmission unit 113 to cause the wireless communication module 114 to transmit a defect occurrence notification mail. The transmission unit 113 and the wireless communication module 114 transmit a defect occurrence notification mail to the administrator. The inconvenience notification mail will be described later. Then, the process returns to step S1.

  On the other hand, when it is determined that the active power is within the normal range, the processing unit 112 determines whether or not the disconnection / disconnection is restored (step S33). For example, it is determined whether the disconnection / disconnection flag is set on. When it is determined that the disconnection / disconnection is restored, the processing unit 112 performs a disconnection / disconnection recovery process (step S35). Specifically, the processing unit 112 sets, for example, a disconnection / disconnection flag to OFF, and outputs an instruction to the transmission unit 113 to cause the wireless communication module 114 to transmit a failure recovery notification mail. The transmission unit 113 and the wireless communication module 114 transmit a failure recovery notification mail to the administrator. Then, the process returns to step S1. In addition, also when it is judged that it is not restoration of disconnection and a disconnection by step S33, it returns to step S1.

  By carrying out the processing as described above, the state notification device 1 automatically determines whether a light bulb type aviation obstacle light is used or a neon tube type aviation trouble light is used. Thus, by specifying an appropriate threshold value and comparing it with the active power, it is possible to appropriately notify the occurrence of a defect or the state of occurrence of a defect. In addition, notifications are also given for other problems and the like so that it is possible to avoid human patrols as much as possible.

  Whether or not the voltage is detected in step S1 can be determined from the waveform data because the waveform is measured, and it is not necessary to provide a separate voltage detection circuit, which contributes to cost reduction. Further, since the mobile phone network is used as it is, there is no need to provide a separate management facility such as a server, and costs are reduced in this respect as well. Further, as will be described below, since the electric double layer capacitor is used without introducing a battery in the event of a power failure, the maintenance cost is reduced by eliminating the replacement cost when the battery is deteriorated. Further, since the structure is simple and the size can be reduced, the cost is reduced also in this respect.

  Next, an example of the defect occurrence notification mail is shown in FIG. In the example of FIG. 29, the transmission date and time, the telephone number of the status notification device 1 (0808064xxxx), the error message (Lamp failure. Act), the number of lights (Lamp = 3), and the charging voltage (CV = 2.53V) And effective current (Arms = 2.34A), effective voltage (Vrms = 98.8V), active power (AP = 168.2W), and power factor (PF = 0.72). Note that the charging voltage is a charging voltage of the electric double layer capacitor 116 described below and is not described above, but is measured by the processing unit 112 or the like. In response to an instruction from the processing unit 112, the transmission unit 113 generates the above-described defect occurrence notification mail data and causes the wireless communication module 114 to transmit the data using a predetermined protocol.

  An example of the power failure occurrence notification mail is shown in FIG. In the example of FIG. 30, the transmission date and time, the telephone number (0808064xxxx) of the status notification device 1, the power failure occurrence message (Power downed. Act / Lamp failure. Act), the number of lights (Lamp = 1), and the charging voltage (CV = 2.65V), effective current (Arms = 0.11A), effective voltage (Vrms = 3.8V), active power (AP = 1.9W), and power factor (PF = 1.00). In response to an instruction from the processing unit 112, the transmission unit 113 generates data of the power failure occurrence notification mail as described above, and causes the wireless communication module 114 to transmit the data using a predetermined protocol.

  An example of the power failure recovery notification mail is shown in FIG. In the example of FIG. 31, the transmission date and time, the telephone number (0808064xxxx) of the state notification device 1, the power recovery occurrence message (Power downed. Ret), the number of lighting (Lamp = 0), and the charging voltage (CV = 2.51V) And effective current (Arms = 0.17A), effective voltage (Vrms = 74.7V), active power (AP = 4.5W), and power factor (PF = 1.00). In response to an instruction from the processing unit 112, the transmission unit 113 generates data for the power failure recovery notification mail as described above, and causes the wireless communication module 114 to transmit the data using a predetermined protocol.

  In addition to the mail described above, (1) initial setting mail, (2) initial setting completion mail, (3) initial measurement completion mail, (4) regular communication mail, (5) command mail, (6) test Mail, (7) Request mail is processed by the aviation trouble light unsuccessful notification system.

  (1) The initial setting e-mail is transmitted from the administrator terminal or the like by the administrator in order to set the state notification device 1 in a monitorable state. When the initial setting mail data is received via the wireless communication module 114 and the transmission unit 113, the processing unit 112 performs initial setting and starts monitoring.

  (2) The initial setting completion mail is for notifying that the initial setting mail has been received and the initial setting has been completed. When the initial setting is completed, the processing unit 112 causes the transmission unit 113 and the wireless communication module 114 to transmit.

  (3) The initial measurement completion mail is for notifying that the initial measurement is completed and the mode is shifted to the normal monitoring mode. When the initial measurement is completed, the processing unit 112 causes the transmission unit 113 and the wireless communication module 114 to transmit.

  (4) The regular communication mail is for regularly reporting that the status notification device 1 is operating and the status of the aviation obstacle lights 3a to 3d. The processing unit 112 causes the transmission unit 113 and the wireless communication module 114 to periodically transmit the measurement and calculation results, the lighting state of the aviation obstacle light, and the like according to the held clock.

  (5) The command mail is transmitted from the administrator terminal or the like by the administrator in order to make various settings to the status notification device 1. When the command mail data is received via the wireless communication module 114 and the transmission unit 113, the processing unit 112 performs various settings according to the command mail data.

  (6) The test mail is for notifying the state of the processing unit 112 and the state of the wireless communication module 114 when the TEST command is transmitted by the command mail. The processing unit 112 causes the transmission unit 113 and the wireless communication module 114 to transmit the state of the processing unit 112, the state of the wireless communication module 114, and the like.

  (7) The request mail is for notifying the lighting state of the aviation obstacle lights 3a to 3d when the REQUEST command is transmitted by the command mail. The processing unit 112 causes the transmission unit 113 and the wireless communication module 114 to transmit the lighting state of the aviation obstacle lights 3a to 3d.

  By limiting the interface to e-mail in this way, setting and maintenance are simplified, thereby reducing costs.

  Next, the configuration of the power supply unit 115 will be described with reference to FIG. The power supply unit 115 includes a normal power supply circuit 1151 for supplying power to the processing unit 112 and the like in a normal state, a charging power supply circuit 1152 for reducing the voltage in a normal state and charging the electric double layer capacitor 116, and a power failure A backup power supply circuit 1153 for boosting the discharge voltage from the electric double layer capacitor 116 and supplying power to the processing unit 112 and the like.

  In normal times, power is supplied to the processing unit 112 and the like via the normal power supply circuit 1151 and the electric double layer capacitor 116 is charged via the charging power supply circuit 1152. When a power failure occurs, the electric double layer capacitor 116 automatically discharges to supply power to the processing unit 112 and the like via the backup power supply circuit 1153.

  In the present embodiment, the electric double layer capacitor 116 is used instead of the battery in order to reduce the maintenance cost. By adopting the electric double layer capacitor 116, it is possible to avoid periodic replacement. In this embodiment, the purpose is not to maintain all the functions such as the processing unit 112 continuously from the power failure to the power recovery, and it is sufficient that the power failure notification mail can be transmitted at the time of the power failure and does not function after the transmission is completed. Good. On the other hand, the purpose is to quickly charge at the time of power recovery and to respond immediately to another power outage. An electric double layer capacitor is suitable for such purposes.

  The capacity of the electric double layer capacitor 116 is sufficient if it can store energy capable of maintaining its function until the power failure notification mail is transmitted as described above. For example, the power supply available time can be calculated by dividing a value obtained by multiplying the energy that can be stored in the electric double layer capacitor 116 by the conversion efficiency by the necessary power. Accordingly, there is no problem as long as this power supply available time is longer than the time required to complete the transmission of the power failure notification mail.

  By adopting such a power supply circuit, it is possible to easily cope with power failure and power recovery. In addition, cost reduction can be achieved.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this. For example, the processing unit 112 includes a processor, a memory, and a program that is executed by the processor and performs the processing described above, but may be implemented by a dedicated circuit. The same applies to the transmission unit 113.

  An example of the contents of the mail is shown in FIGS. 29 to 31. However, it is an example, and more data may be included, or only the minimum necessary notification type may be notified.

  In addition, because the necessity is low this time, there is no distinction between disconnection and ball breakage for a neon tube type aviation obstruction light, but for example, it can be distinguished with a certain degree of accuracy considering the power factor. The possibility of a broken ball or a broken wire may be presented.

  In addition, when a capacitor having the same characteristics as the electric double layer capacitor is present, it can be replaced with the capacitor.

  Further, the mobile phone includes other configurations capable of packet communication such as PHS (Personal Handyphone System).

  In the above, the case where there are four aviation obstacle lights is shown, but the present invention is not limited to four lights, and depends on the number of lights if the threshold can be appropriately set by the method described above. It is not a thing.

  Furthermore, another configuration that performs the same function may be adopted for the mechanism for measuring current and voltage.

  Moreover, although the example which employ | adopts a wireless communication module was shown, a wired communication module may be used in the place where a wired communication line already exists.
