  According to such a fault location detection system, when any fault occurs on the power line, the detector 3 installed downstream from the position where the fault occurs detects a power failure. These detectors 3 wirelessly transmit data (detection data) indicating whether or not the current value flowing when a power failure is detected exceeds a predetermined threshold value. The information processing apparatus receives the detection data transmitted from each detector and stores it in the detection data storage unit. The user refers to the detection data stored in the detection data storage unit and the installation location data stored in the installation location storage unit to turn on / off the breaker and turn on / off the load equipment. It is possible to detect where a failure has occurred on the power line without performing such operations as above.

== Overall structure ==
FIG. 1 is a diagram showing a configuration of a failure location detection system according to an embodiment of the present invention. The failure location detection system identifies a location where a failure has occurred in the outdoor power line 1 and the indoor power line 2 when a failure such as a power failure occurs indoors. This system includes a plurality of detectors 3 (3a to 3h, etc.) installed on a power line, and an information processing device 4 that outputs a location where a failure has occurred based on a signal from the detector 3. It is configured.

  The detector 3 is a device that detects a power failure that occurs due to electric leakage or overload on the power line, and is arranged at a plurality of locations on the power line. For example, the detector 3a is connected to a pole ketch 5 provided on the utility pole. The detector 3b is also connected to the outdoor switch 6 to which a lead-in line from a utility pole to a house or the like is connected. And on the indoor power line 2 drawn indoors via the outdoor switch, detectors 3c to 3e are connected to the breakers 9a and 9b provided in the indoor main switch 7 and the distribution board 8. Detectors 3f to 3h are also connected to switches 15a and 15b for controlling power supply / disconnection to a receiving port (outlet or the like) 12 to which the telephone 10 or the television 11 is connected, a ventilation fan 13 or a lighting fixture 14 or the like. Yes.

  The information processing apparatus 4 is an apparatus such as a personal computer or PDA (Personal Digital Assistance), and transmits data transmitted from the detector 3 wirelessly to a wireless base station 16 and a network 17 such as a LAN (Local Area Network). Can be received via.

== Configuration of detector ==
FIG. 2 shows the configuration of the detector 3. The detector 3 includes an ammeter 31, a voltmeter 32, a storage battery 33, an antenna 34, a memory 35, a detection data generation unit 36, and a detection data transmission unit 37. The ammeter 31 and the voltmeter 32 are for measuring a current value and a voltage value at a position where the detector 3 is connected on the power line. Electric power is stored in the storage battery 33 by a current flowing on the power line during normal operation. When a power failure occurs on the power line, the detector 3 is operated by the power stored in the storage battery 33. In addition, it is good also as using a primary battery, a solar cell, etc. instead of the storage battery 33. FIG.

  The memory 35 is a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory), and includes a current value storage unit 38, a threshold storage unit 39, and a terminal number storage unit 40 as storage areas. . The current value storage unit 38 continuously stores a current value for a predetermined period output from the ammeter 31. For example, when a power failure occurs on the power line due to overload, the current value at the time of overload immediately before the power failure occurs is also stored in the current value storage unit 38. The threshold value storage unit 39 stores a threshold value indicating the upper limit of the current at the position where the detector 3 is installed. For example, in the case of the detector 3d connected to the breaker 9a, the current value (threshold value) when the breaker 9a cuts off the current is stored in the threshold value storage unit 39. The terminal number storage unit 40 stores a terminal number (identifier) for identifying the detector 3.

  A voltage value measured by the voltmeter 32 is input to the detection data generation unit 36. The detection data generation unit 36 generates detection data when the voltmeter 32 detects a power failure, that is, when the voltage value output from the voltmeter 32 becomes zero. FIG. 3 is a diagram illustrating the structure of the detection data 50. The detection data 50 includes a terminal number, an abnormal signal, and a current current value. The terminal number is stored in the terminal number storage unit 40. The current value stored in the current value storage unit 38 is set to the current value immediately before the voltage value becomes zero. The abnormal signal is data indicating whether or not the current value exceeds a threshold value.

  FIG. 4 shows the contents of the abnormal signal generated by the detection data generation unit 36. When the detector 3 is connected to the receiving port 12, the detection data generation unit 36 compares the current value with the threshold value, and sets “1” to the abnormal signal if the current value exceeds the threshold value. If the threshold is not exceeded, “2” is set to the abnormal signal. In addition, when the detector 3 is connected to the breaker 9a or the switch 15a, the detection data generation unit 36 compares the current current value with a threshold value, and if the current current value exceeds the threshold value, the detection signal “ 4 ”is set, and if the threshold is not exceeded,“ 5 ”is set for the abnormal signal. When the breaker 9a and the switch 15a are normally disconnected by operation, “3” is set as the abnormal signal.

  The detection data transmission unit 37 wirelessly transmits the detection data generated by the detection data generation unit 36 via the antenna 34. The detection data generation unit 36 and the detection data transmission unit 37 are realized by a CPU (not shown) included in the detector 3 executing a program stored in the memory 35 or the like.

  Note that, even when no power failure is detected, the detection data generation unit 36 generates detection data 50 at predetermined intervals, and the detection data transmission unit 37 transmits the detection data 50 wirelessly. In this case, a signal indicating that no abnormality has occurred (a signal other than “1” to “5”) is set as the abnormal signal, and the current value stored in the current value storage unit 38 is the current value. Is set.

== Detector mode ==
Next, a mode in which the detector 3 is connected to the power line will be described. FIG. 5 is a diagram illustrating an appearance of a switch 60 provided on the power line, corresponding to the switches 15a and 15b illustrated in FIG. The switch 60 is provided on an indoor wall surface or the like, and includes an operation unit 61 for operating power on / off of the electric device. As shown in FIG. 6, the ammeter 31 and the voltmeter 32 of the detector 3 are connected to the upstream terminal 62 of the switch 60, and the voltmeter 32 is connected to the downstream terminal 63. Here, the upstream side is the power plant side in the power line, and the downstream side is the electric equipment side.

  In the case of the detector 3 connected to the switch 60 in this way, the detection data generation unit 36 generates an abnormal signal based on the current value and voltage value on the upstream side of the switch 60 and the voltage value on the downstream side. FIG. 7 is a diagram illustrating an abnormal signal generation pattern in the detector 3 connected to the switch 60. As shown in the figure, when the upstream voltage value becomes zero, the detection data generation unit 36 determines that the abnormal signal is “4: over threshold” or “5” by comparing the current value measured on the upstream side with the threshold value. : Threshold not exceeded ”is set. Further, when the upstream voltage value is not zero and the downstream voltage value is zero, the detection data generation unit 36 determines that the switch 60 is disconnected by the operation of the operation unit 61, and generates an abnormal signal. Set “3: Switch OFF”. Further, when both the upstream side and the downstream side are not zero, no power failure has occurred at the position where the switch 60 is installed, and thus no abnormal signal is generated.

  1, not only the switches 15a and 15b in FIG. 1, but also the pole top ketch 5, the outdoor switch 6, the indoor main switch 7, the breaker 9a and the like are connected to the detector 3 as shown in FIG. . Further, the abnormal signal generation pattern in the detection data generation unit 36 in this case is also as shown in FIG.

  FIG. 8 is a diagram showing the appearance of an outlet 70 provided on the power line, corresponding to the receptacle 12 shown in FIG. The outlet 70 is provided on an indoor wall surface or the like, and includes outlets 71a and 71b into which a power plug of an electric device is inserted. As shown in FIG. 9, the ammeter 31 and the voltmeter 32 of the detector 3 are connected to a power line 73 that connects the outlets 71 a and 71 b of the outlet 70 and the indoor power line 2. When the voltage value output from the voltmeter 32 becomes zero, the detection data generation unit 36 acquires the current value immediately before the voltage value becomes zero from the current value storage unit 38, and abnormally detects based on the acquired current value. Detection data 50 in which “1: threshold exceeded” or “2: threshold not exceeded” is set in the signal is generated.

  FIG. 10 is a view showing the appearance of a power socket 80, which is another form of the receptacle 12 shown in FIG. The power socket 80 includes a housing 81 that houses the detector 3. Then, the insertion ports 84a and 84b into which the power plugs of the electrical devices are inserted are provided on the front surface 82 of the casing 81, and the plugs 85a and 85b for inserting into the outlet are provided to protrude from the rear surface 83 of the casing 81. Yes. The user of the electric device can connect the power plug of the electric device to the outlet via the power socket 80. That is, the power socket 80 is used when the detector 3 as shown in FIG. 9 is not connected to the outlet. In addition, the whole power socket 80 provided with the detector 3 corresponds to the detector in the present invention.

  FIG. 11 is a diagram illustrating a connection mode of the detector 3 in the power socket 80. As shown in the figure, the ammeter 31 and the voltmeter 32 of the detector 3 are connected to a power line 86 that connects the plugs 84a and 84b and the plugs 85a and 85b. When the voltage value output from the voltmeter 32 becomes zero, the detection data generation unit 36 acquires the current value immediately before the voltage value becomes zero from the current value storage unit 38, and abnormally detects based on the acquired current value. Detection data 50 in which “1: threshold exceeded” or “2: threshold not exceeded” is set in the signal is generated.

== Configuration of information processing apparatus ==
FIG. 12 is a diagram illustrating a hardware configuration of the information processing apparatus 4. The information processing apparatus 4 includes a CPU 101, a memory 102, a storage device 103, a recording medium reading device 104, a communication interface 105, an input device 106, and a display 107. The CPU 101 controls the information processing apparatus 4 by executing a program stored in the memory 102. The storage device 103 is, for example, a hard disk drive or the like, and stores programs, various data, and the like. When the CPU 101 executes the program, the program stored in the storage device 103 is sequentially read and stored in the memory 102. The recording medium reading device 104 can read a program recorded on a recording medium 108 such as a CD-ROM and store the program in the storage device 103.

  The communication interface 105 is an interface for transmitting and receiving data via the network 17. The input device 106 is a device that receives data input, and is, for example, a keyboard or a mouse. The display 107 displays various types of information, such as a CRT (Cathode Ray Tube) display or a liquid crystal display.

  FIG. 13 is a diagram illustrating a configuration of functions included in the information processing apparatus 4. The information processing apparatus 4 includes a detection data receiving unit 111 and a failure location output unit 112 that are realized by the CPU 101 executing a program stored in the memory 102. The detection data receiving unit 111 receives the detection data 50 transmitted wirelessly from the detector 3 installed on the power line. Then, the failure location output unit 112 identifies the location where the failure has occurred on the power and the cause of the failure based on the received detection data 50 and the like, and displays them on the display 107. Details of operations of the detection data receiving unit 111 and the failure location output unit 112 will be described later.

== Database structure ==
Next, the structure of the database provided in the information processing apparatus 4 will be described. FIG. 14 is a diagram illustrating an example of a position information database (installation location storage unit and detector information storage unit) 130 that stores a location where the detector 3 is installed on the power line. In the position information database 130, a terminal number, an installation location (Japanese name), position information, a threshold value, and a terminal load flag are stored in association with each other. The terminal number is set to the terminal number of the detector 3 installed on the power line, and the installation location (Japanese name) is the name in Japanese of the location where the detector 3 is installed, for example, “ “Outdoor switch” and “Inter-customer” are set.

  And the data (installation location data) which show the installation location on the power line of the detector 3 are set in the position information. The position information will be described with reference to FIG. As shown in FIG. 15, outdoor / indoor power lines are hierarchically configured. That is, a hierarchy is formed from the upstream side of the power line to the downstream side, such as the pole top ketch 5, the outdoor switch 6, the indoor main switch 7, the distribution board 8, the receiving port 12, and the switches 15a and 15b. Yes. The position information indicates the installation location of each detector 3 in this hierarchical relationship.

  For example, the position information of the pole top ketch 5 is “0”, and the position information of the outdoor switch 6 on the downstream side is “1”. Further, the position information of the indoor main switch 7 is “2”, and the position information of the breaker provided in the distribution board 8 on the downstream side is “3-1” to “3-5”. And the positional information of the switch etc. in the downstream of the breaker (circuit 1 “entrance”) whose positional information is “3-1” is “3-1-1” to “3-1-3”.

  Moreover, the threshold value stored in the threshold value storage unit 39 of each detector 3 is set as the threshold value. When the detector 3 is arranged at the end of the power line, that is, the detector 3 is connected to a receiving port (outlet 70 / power socket 80), a switch 60 for controlling the turning on / off of electric power to an electric device, or the like. When connected, “1” is set to the end load flag.

  Note that each piece of information stored in the position information database 130 is registered by the user using the input device 106 of the information processing device 4 when using the fault location detection system.

  FIG. 16 is a diagram illustrating an example of a failure information database (detection data storage unit) 140 that stores failure information on the power line. In the failure information database 140, a terminal number, a load facility name, position information (wireless LAN), an abnormality signal, an abnormality detection current value, and a current current value are stored in association with each other. In the load facility name, names of electrical devices, switches, and the like at the position where the detector 3 is connected are set. For example, the load facility name of the detector 3 connected to the indoor main switch 7 is set to “indoor main switch”, and the load facility name of the detector 3 connected to the switch 15b for the lighting fixture 14 between the customers. Is set to “lighting”.

  In the position information (wireless LAN), data indicating the position (longitude, latitude, altitude, etc.) of the detector 3 measured by the base station 15 based on the detection data 50 transmitted from the detector 3 is set. . An abnormal signal included in the detection data 50 transmitted from the detector 3 is set as the abnormal signal. Then, the current value included in the detection data 50 when the abnormality signals “1” to “5” are set in any of the detection data 50 is set in the current value at the time of abnormality detection. In addition, the current value included in the latest detection data 50 transmitted from the detector 3 is set as the current value.

  The position information, abnormality signal, abnormality detection current value, and current current value are updated by the detection data receiving unit 111 that has received the detection data 50.

== Fault location output processing ==
Next, a failure location output process that is a process for outputting a location where a failure has occurred on the power line will be described. When the detection data receiving unit 111 receives the detection data 50, the fault location output unit 112 of the information processing device 4 is based on the abnormality signal stored in the fault information database 140 and the position information stored in the position information database 130. Execute fault location output processing. Note that three types of failure location output processing are prepared by combinations of abnormal signals from the upstream and downstream detectors 3 on the power line illustrated in FIG.

  17 and 18 show patterns for determining which type of processing the failure location output unit 112 selects depending on the combination of the abnormal signals of the upstream and downstream detectors 3. In the table, a portion where “-” is displayed indicates a combination that is considered to have no failure or a combination that is impossible. The “switch” in the table includes not only the switch 15b for the lighting fixture 14, but also the outdoor switch 6 and the breaker 9a.

The determination table 1 in FIG. 17 shows a determination pattern when an abnormal signal is detected from the upstream and downstream detectors 3. For example, the abnormal signal of the detector 3 connected to the upstream switch is “4: threshold exceeded”, and the abnormal signal of the detector 3 connected to the downstream receiving port is “1: threshold exceeded”. In this case, the determination type 1 process is selected. Further, for example, the abnormal signal of the detector 3 connected to the upstream switch is “5: threshold is not exceeded”, and the abnormal signal of the detector 3 connected to the downstream receiving port is “1: threshold not yet set”. If it is “super”, the determination type 2 process is selected.
In addition, since the receiving port cannot be on the upstream side in the power line, all the locations of the receiving port on the upstream side are “−”. The abnormal signal “3” is “−” because it indicates that the switch is normally disconnected.

Further, in the determination table 2 of FIG. 18, an abnormal signal is not detected from the detector 3 connected to the upstream switch, and an abnormal signal is detected from the detector 3 connected to the downstream receiving port or switch. The determination pattern in the case of being performed is shown. For example, when the abnormal signal of the detector 3 connected to the receiving port is “1: threshold exceeded”, the processing of the judgment type 3 is selected, and when the abnormal signal is “2: threshold not exceeded”, The type 2 process is selected.
When the abnormal signal is “3” or when no abnormal signal is detected from all the downstream detectors 3, it is regarded that no failure has occurred and is “−”.

  When the fault location output unit 112 acquires the abnormal signal set in the fault information database 140, the fault part output unit 112 obtains the terminal number of the detector 3 installed upstream or downstream of the detector 3 that detected the abnormal signal as position information. Obtained based on the position information in the database 130, obtain an abnormal signal corresponding to the terminal number from the failure information database 140, and select a process based on the decision table 1 and decision table 2.

  In this processing, the failure location output unit 112 outputs data indicating the location where the failure has occurred on the power line and the cause of the failure. That is, the failure location output unit 112 displays the failure occurrence location and the cause of the failure on the display 107 based on the data. Here, the data output by the failure location output unit 112 includes the location information stored in the location information database 130, the location information such as longitude and latitude stored in the failure information database 140, and the location information stored in the failure information database 140. It is the name of the load equipment that is being used. The fault location output unit 112 displays the fault location according to a pre-registered indoor structure drawing based on position information such as longitude and latitude stored in the fault information database 140. It can also be displayed on 107.

  Next, details of each processing of the judgment types 1 to 3 will be described. FIG. 19 is a flowchart of determination type 1 processing. First, the failure location output unit 112 checks whether the abnormal signal from the downstream detector (terminal) 3 is “1” or “4”, that is, “exceeding threshold” (S1901). When the abnormal signal is “1” or “4” (S1901: Yes), the failure location output unit 112 generates data indicating that a failure has occurred at a location where the downstream detector 3 is connected. Output (S1902).

  When the abnormal signal from the downstream detector 3 is neither “1” nor “4”, that is, when it is “threshold not exceeded” (S1901: No), the failure location output unit 112 outputs the upstream detector 3 Among the plurality of detectors 3 on the downstream side, the current value at the time of abnormality detection of the detector 3 “not exceeding the threshold” is acquired from the failure information database 140. Then, the total value of the acquired current values is compared with the threshold value of the upstream detector 3 (S1903).

  If the total value of the current values of the downstream detector 3 is equal to or less than the threshold value of the upstream detector 3 (S1903: Yes), the failure location output unit 112 determines that no failure has occurred in the location. (S1904). If the total value of the current values of the downstream detector 3 is greater than the threshold value of the upstream detector 3 (S1903: No), the fault location output unit 112 determines that the circuit (the upstream detector 3). The data indicating that the entire downstream side is overloaded is output (S1905).

  Subsequently, the failure location output unit 112 checks whether or not there is a detector 3 that has not confirmed an abnormal signal among the downstream detectors 3 with respect to the target upstream detector 3 (S1906). When the unconfirmed detector 3 is present (S1906: No), the failure location output unit 112 acquires the abnormal signal of the unconfirmed detector 3 from the failure information database 140 (S1907), and the above-described processing (S1901 to S1905). Repeatedly. When the confirmation of the abnormal signal of all the detectors 3 on the downstream side is completed (S1906: Yes), the process ends.

  That is, in the determination type 1 process, when the detection data 50 from the downstream detector 3 indicates that the current value exceeds the threshold value, the location where the downstream detector 3 is installed. Data indicating that is the location of the failure is output. The detection data 50 from the upstream detector 3 indicates that the current value exceeds the threshold value, and the detection data 50 from the plurality of downstream detectors 3 has the current value as the threshold value. If the sum of the current values included in the detection data 50 from the plurality of downstream detectors 3 is larger than the threshold value of the upstream detector 3, the upstream side Data indicating that the entire downstream side of the detector is overloaded is output.

  FIG. 20 is a flowchart of determination type 2 processing. As shown in the determination table 1 and the determination table 2, the processing of the determination type 2 is executed when neither the upstream detector 3 nor the downstream detector 3 exceeds the threshold value. First, the fault location output unit 112 acquires the threshold value of the upstream detector 3 and the threshold values of the plurality of detectors 3 on the downstream side of the detector 3 from the position information database 130. Then, the failure location output unit 112 checks whether or not the total threshold value of the downstream detector 3 is equal to or greater than the threshold value of the upstream detector 3 (S2001).

  When the sum of the threshold values of the downstream detector 3 is equal to or greater than the threshold value of the upstream detector 3 (S2001: Yes), the failure location output unit 112 can detect an abnormality due to a failure or the like of the upstream detector 3. It is determined that it is not, and processing of determination type 1 is executed (S2002). When the sum of the threshold values of the downstream detector 3 is less than the threshold value of the upstream detector 3 (S2001: No), the fault location output unit 112 further includes the upstream detector 3 and the detector 3 further. Data indicating that there is a failure or disconnection with the upstream detector 3 is output (S2003).

  Subsequently, the failure location output unit 112 checks whether there is a detector 3 that has not confirmed an abnormal signal among the downstream detectors 3 with respect to the target upstream detector 3 (S2004). When there is an unconfirmed detector 3 (S2004: No), the failure location output unit 112 acquires an abnormal signal of the unconfirmed detector 3 from the failure information database 140 (S2005), and the above-described processing (S2001 to S2004). Repeatedly. When the confirmation of the abnormal signal of all the detectors 3 on the downstream side is completed (S2004: Yes), the process is finished.

  That is, in the determination type 2 process, the detection data from the upstream detector 3 and the downstream detector 3 indicate that the current value does not exceed the threshold value, and a plurality of downstream data When the sum of the threshold values of the detector 3 is smaller than the threshold value of the upstream detector 3, data indicating that the upstream side of the upstream detector 3 is a fault occurrence location is output.

  FIG. 21 is a flowchart of the determination type 3 process. As shown in the determination table 2, the processing of the determination type 3 is executed when an abnormality is not detected in the upstream detector 3 and a threshold excess is detected in the detector 3 installed at the end of the power line. . First, the fault location output unit 112 acquires the threshold value of the upstream detector 3 and the threshold values of the plurality of detectors 3 on the downstream side of the detector 3 from the position information database 130. Then, the failure location output unit 112 checks whether or not the sum of the threshold values of the downstream detector 3 is equal to or greater than the threshold value of the upstream detector 3 (S2101).

  When the sum of the threshold values of the downstream detector 3 is equal to or greater than the threshold value of the upstream detector 3 (S2101: Yes), the fault location output unit 112 can detect an abnormality due to a failure of the upstream detector 3 or the like. It is determined that it is not, and processing of determination type 1 is executed (S2102). When the sum of the threshold values of the downstream detector 3 is less than the threshold value of the upstream detector 3 (S2101: No), the failure location output unit 112 is a location where the detector 3 that has detected an excess of the threshold is installed. The data indicating that is overloaded is output (S2103).

  Subsequently, the failure location output unit 112 checks whether or not there is a detector 3 that has not confirmed an abnormal signal among the downstream detectors 3 with respect to the target upstream detector 3 (S2104). When there is an unconfirmed detector 3 (S2104: No), the failure location output unit 112 acquires an abnormal signal of the unconfirmed detector 3 from the failure information database 140 (S2105), and the above-described processing (S2101 to S2104). Repeatedly. When the confirmation of the abnormal signal of all the detectors 3 on the downstream side is completed (S2104: Yes), the process ends.

  That is, in the determination type 3 process, when the detection data 50 from the downstream detector 3 indicates that the current value exceeds the threshold value, the location where the detector 3 is installed is excessive. Data indicating a load is output.

  The configuration and operation of the failure location detection system have been described above. As described above, when any failure occurs on the power line, the detector 3 installed downstream from the position where the failure occurs detects a power failure. And these detectors 3 transmit the detection data 50 containing the comparison result of the electric current value and the predetermined threshold value which were flowing when the power failure was detected by radio | wireless. The information processing apparatus 4 receives the detection data 50 transmitted from each detector 3 and stores it in the failure information database 140. The user refers to the abnormality signal stored in the failure information database 140 and the position information stored in the position information database 130 to turn on / off the breaker and turn on / off the load facility. Thus, it is possible to quickly detect where a failure has occurred in the power line without performing such work.

  Further, the user can more quickly detect the location where the failure has occurred on the power line and the cause of the failure based on the data output from the failure location output unit 112 of the information processing device 4.

  Further, the detector 3 is connected to an outdoor switch, a switch of an electric device, or the like. As described above, when the detector 3 is connected to the switch, the location where the failure has occurred on the power line is specified by the position of the switch. Therefore, the user can know the location where the failure has occurred from the position of the switch, and the failure location can be easily recognized.

  The detector 3 is also connected to an outlet into which a power plug of the electric device is inserted. Thereby, the user can know the location where the failure has occurred on the power line from the position of the outlet, and the failure location can be easily recognized.

  In addition, by using the power socket 80 with the built-in detector 3, when the electrical device is connected to the outlet, the electrical equipment is installed at the place where the electrical device is installed without connecting the detector 3 to the outlet. Can detect the failure.

  Although the embodiment of the present invention has been described above, the above description of the embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. It goes without saying that the present invention can be changed and improved without departing from the gist thereof, and that the present invention includes equivalents thereof.

  For example, in the present embodiment, the information processing apparatus 4 is installed indoors, but may be installed in an electric power company or the like. In this case, the detection data 50 transmitted wirelessly from the detector 3 is transmitted to the information processing apparatus 4 via a network such as the Internet.
