Abstract

PROBLEM TO BE SOLVED: To provide a maintenance information providing device capable of providing arrival information of a proper maintenance timing.SOLUTION: In a maintenance information providing device, according to weighting which is set to be heavier as the operation environment of a power generation device for emergency is harsher and lighter as the operation environment is more moderate, when a parameter value increasing with time lapse exceeds a preset threshold value on the basis of device attribute information (S111; Yes), arrival information of a maintenance timing is output to a display and a printer (S119). Accordingly, as compared with a case where the operation environment of the power generation device for emergency is moderate, the parameter value exceeds the threshold value and the arrival information of the maintenance timing is output to the display or the like earlier when the operation environment is harsher. Since lightness or heaviness is varied on the basis of climate information in a district in which the power generation device for emergency (S107) is installed, the arrival information of the maintenance timing including the variation of the operation environment of the power generation device for emergency can be output.

Description

  The present invention relates to a maintenance information providing apparatus that provides arrival information of a time when maintenance work such as maintenance, inspection, and repair should be performed.

  As a technique related to provision of maintenance information, for example, there is a “maintenance information provision system” disclosed in Patent Document 1 below. In this technology, the status of each information appliance is monitored by a maintenance information providing device via a communication line, and maintenance information is notified to the user of the information appliance based on the status of the information appliance and a predetermined threshold.

Examples of the “load” include electrical machine equipment such as an air conditioner, an elevator, and lighting equipment such as an office building and a hospital, and fire prevention and smoke removal equipment such as a sprinkler, a fire shutter, and a fire alarm. The emergency power generator 50 is installed outdoors or outdoors, for example, on the rooftop of a building, in order to easily exhaust the exhaust gas discharged from the engine 52 to the outside.

  The engine 52 is an internal combustion engine such as a piston engine or a gas turbine engine, and is a driving force source that gives rotational energy to the generator 53. In this embodiment, a diesel engine is used, and if the output capacity of the generator 53 is large depending on the output capacity of the generator 53, the displacement of the engine 52 is set to be large. .

However, an air cooling method that cools the engine 52 by taking in outside air. There is also. The engine 52 differs in the number of parts and the structure constituting the engine 52 depending on the displacement and the cooling method.

  The generator 53 is a power device that generates AC power by converting rotational energy from the engine 52 into electric energy by electromagnetic induction, and the AC power output from the generator 53 is an emergency power source. Although not shown, the emergency power generator 50 is connected to a load transmission line for transmitting the generated emergency power.

The control unit 56 includes an unillustrated CPU, memory, EEPROM, input / output interface, operation panel, communication interface, and the like, and is connected to a cell motor 54, a fuel pump 58, a preheating heater, a stop solenoid, and the like. In the memory of the control unit 56, a control program for starting and stopping the engine 52 is stored. Note that a voltage sensor (not shown) that measures the voltage of the commercial power supply is also connected to the control unit 56 so that the occurrence of a power failure of the commercial power supply can be detected.

  The battery 55 is a rechargeable secondary battery that can generate a predetermined DC voltage (for example, 24 V), and is electrically connected to the control unit 56 in addition to the above-described cell motor 54, fuel pump 58, and preheating heater. ing. As a result, the engine 52 can be started and the control unit 56 can be driven without receiving power supply from the outside. The battery 55 is typically a lead storage battery, and structurally, there are a sealed lead storage battery (control valve type) and a liquid lead storage battery (vent type). Moreover, it is classified into a clad type, a paste type and a tudle type according to the type of electrode. The battery 55 has different temperature characteristics and life depending on the structure and the type of electrode.

  The communication device 59 enables the emergency power generation device 50 to be connected to the Internet 100, and is the same as the communication device 19 configuring the maintenance information providing device 10 described above. Therefore, the communication device 59 corresponds to, for example, a subscriber network termination device (CTU) or an optical line termination device (ONU). Note that an identifier (ID) that can uniquely identify the emergency power generation device 50 is assigned in advance to the communication device 59 provided in the emergency power generation device 50, and the maintenance information providing device 10 uses a plurality of identifiers. The specific emergency power generation device 50 is identified from the emergency power generation device 50. The identifier is, for example, an IP address or a MAC address.

  The engine 52, the generator 53, the cell motor 54, the battery 55, the control unit 56 and the like are accommodated in the housing 51. The casing 51 is usually made of a metal plate, and waterproof and dustproof measures are taken in order to prevent rainwater and dust from entering from the outside. The surface of the metal plate is painted in a relatively bright color such as white or light gray to suppress heat absorption due to sunlight irradiation. In addition, when the emergency power generation device 50 is installed in a geographical area close to the sea, such as a coastal area, the metal plate of the casing 51 has a rust prevention process (for example, an Rust coating, rust prevention plating, etc.) are applied. In addition, when installed on the surface of main roads and along railway lines, some have taken anti-vibration measures to suppress vibrations that can be transmitted through the ground.

  The emergency power generator 50 of this embodiment includes a plurality of sensors. For example, a voltage sensor that measures the output voltage of the battery 55 or a voltage sensor that measures an AC voltage output from the generator 53. In addition, a temperature sensor that measures the temperature of the cooling water flowing through the radiator, a liquid amount sensor that can measure the amount of cooling water in the radiator, a temperature sensor that measures the temperature in the housing 51, and the humidity in the housing 51 Humidity sensor that measures In some cases, a liquid level sensor (liquid level sensor) capable of measuring the liquid level (liquid level) of the fuel amount stored in the fuel tank 57 may be provided. Further, there may be a liquid amount sensor that can measure the amount of engine oil. These sensors are connected to the Internet 100 via the control unit 56 or directly, and are transmitted to the maintenance information providing apparatus 10 as data relating to apparatus attribute information.

  By configuring the emergency power generation device 50 in this way, the emergency power generation device 50 uses data measured by a voltage sensor or the like even during normal times when power is supplied from a commercial power source without the generator 53 operating. Can be transmitted to the maintenance information providing apparatus 10 in real time or at regular time intervals.

  Here, device attribute information and the like of the emergency power generation device 50 stored in the hard disk 13 will be described. The hard disk 13 is provided with a device attribute information database that stores device attribute information and an environment attribute information database that stores environment attribute information. The device attribute information is information related to the configuration of the emergency power generation device 50 itself that is the object of the maintenance work, that is, information unique to each emergency power generation device 50, and corresponds to each of the plurality of emergency power generation devices 50. Yes. The environment attribute information is information related to the surrounding environment where the emergency power generation device 50 is installed.

  For example, the paint color applied to the casing 51 and the presence / absence of measures such as waterproof, dustproof, rustproof, and vibration proof correspond to the device attribute information. The thickness of the metal plate constituting the housing 51 also corresponds to the device attribute information. That is, the housing structure corresponds to the device attribute information. Further, the types of the engine 52, the generator 53, the cell motor 54, the battery 55, the fuel pump 58, the cooling method of the engine 52 (whether or not cooling water is used depending on whether it is a water cooling method or an air cooling method, etc.) Equivalent to. Further, the number of parts of the electronic parts constituting the control unit 56 having a heat-resistant temperature of 85 ° C. or less (for example, an electrolytic capacitor), the total number of electrodes of parts that enable mechanical electrical connection such as connectors, etc. Corresponds to attribute information.

  The paint color of the casing 51 affects the temperature rise in the casing 51 in an installation environment in which the emergency power generation device 50 is exposed to direct sunlight, and the battery 55 and the control having lower heat resistance than the engine 52 and the generator 53 are controlled. It affects the degree of failure of the unit 56 and the like. In general, the closer to black, the easier the temperature in the housing 51 rises. For the control unit 56 and the like including parts that are sensitive to temperature (especially electronic parts (for example, electrolytic capacitors)), the degree of occurrence of failure due to temperature rise affects.

  The presence or absence of waterproof or dustproof measures for the casing 51 may be triggered by rainwater or dust entering the casing 51, and the occurrence of a failure of the engine 52, the generator 53, the cell motor 54, the battery 55, the control unit 56, etc. Affects the degree. In addition, the thickness of the metal plate constituting the casing 51 and the presence or absence of rust prevention measures affect the degree of rust and corrosion of the casing 51 due to salt damage in the installation environment where the emergency power generation device 50 is exposed to sea breezes. Further, when rainwater or dust can enter from a corroded portion, the degree of failure of the engine 52 or the like is affected as well as waterproofing and dustproofing measures of the casing 51.

  The presence or absence of anti-vibration measures includes loosening of the screw fastening location of the casing 51 due to continuous external vibration, damage to electronic components and soldered locations of the control unit 56 accommodated in the casing 51, etc. Affects the degree of occurrence. In addition, when rainwater or dust can enter due to loosening of the screw at the fastening portion of the casing 51, the degree of failure of the engine 52 or the like is affected. In addition, the control unit 56 and the like including components that are vulnerable to vibration (particularly electronic components (for example, connectors)) may affect the degree of failure caused by vibration.

  The degree of failure of the engine 52 or the like is greatly affected by the number of different parts depending on the types of the engine 52, the generator 53, the cell motor 54, the battery 55, the fuel pump 58, and the cooling method of the engine 52. Generally, the greater the number of parts, the higher the failure rate (failure rate). The failure rate is an index used for reliability calculation. For example, the failure rate is defined by the number of occurrences per unit time (cases / hour), and this reciprocal is called the mean time between failures (MTBF) (time / case). Based on equipment device uptime. Therefore, such a failure rate is not suitable for the emergency power generator 50 that is stopped during normal times.

  Therefore, in the present embodiment, the device attribute information predetermined for each emergency power generation device 50, such as the number of parts of the engine 52 and the like, the presence / absence of measures such as the paint color and waterproofing applied to the casing 51 described above, and the like. Based on this, a predetermined threshold for each emergency power generator 50 is set and stored in the hard disk 13. These threshold values are determined based on the information related to any one or more of the engine 52, the battery 55, the cooling water of the radiator, the control unit 56, the structure of the casing 51, and the like exemplified above, and the corresponding emergency power generation The device 50 is associated with the corresponding emergency power generation device 50 by an identifier (ID) that can uniquely identify the device 50.

  Such a predetermined threshold value is compared with a parameter value that increases with the passage of time by a maintenance timing notification process described later. This parameter value is also associated with each emergency power generator 50, and an initial value is set for each emergency power generator 50 and stored in the hard disk 13. For example, if it increases by a certain value over time, the parameter value will be changed according to the inspection standard announced by the competent authority in relation to the Fire Service Act, for example, at the time of legal inspection that comes every six months or one year. The initial value of the parameter value is set so as to exceed the threshold value. This time may be a preset periodic inspection time. As a result, when the lightest weight (for example, weight = 1.0) among the weights described below is continuously applied to this parameter value (when the operating environment is the mildest), the maintenance time notification process described later is performed. This makes it possible to make the maintenance time output by the above coincide with the legal inspection time or the periodic inspection time of the emergency power generator 50. That is, at the longest, the arrival information of the maintenance time is output at the time of legal inspection according to a predetermined law or the like and the periodical inspection set in advance.

  In this embodiment, the weight applied to the parameter value is set with a weight between 1.0 and 2.0, for example. Application of weighting to a parameter value is performed, for example, by multiplying an addition value per unit time with respect to the parameter value by “weight”. The weighted value (weight) is determined by the environmental attribute information set for each emergency power generator 50. That is, it is determined based on environment attribute information set in advance with respect to the surrounding environment of the place where the emergency power generation device 50 is installed. For example, the installation location of the emergency power generation device 50 is outdoors (weight = 1.2) exposed to direct sunlight, is outdoors (weight = 1.1) not exposed to direct sunlight, or is indoors (weight = 1.0) or the like. Generally, the emergency power generation apparatus 50 is set so that it is heavier (value is larger) as the operating environment is severer and lighter (value is smaller) as it is milder.

  As an example of weighting, in addition to this, the region or the region where the emergency power generation device 50 is installed is a mountainous part (weight = 1.3) where the temperature fluctuation is intense, or a gentle plain part (weight = 1.0). There is a coastal area (weight = 1.5) that is easily exposed to sea breeze. Also, the installation location is a high humidity area (weight = 1.2), a place along the railway where there is a lot of vibration on a daily basis (weight = 1.2), or in a factory ground with a lot of dust (weight = 1.2) ) Or the like. Furthermore, when installed at the top of a mountain with a high altitude, weighting (weight = 1.3) is performed in consideration of a decrease in dielectric strength due to a low-pressure environment. These pieces of environmental attribute information are stored in an environmental attribute information database provided in the hard disk 13. The weighting applied to the parameter value is associated with each emergency power generation device 50, and is preset for each emergency power generation device 50 and stored in the hard disk 13.

  In this embodiment, the weight is changed based on the weather information obtained from the weather information providing device 90 via the Internet 100 with respect to the weight set in advance for each emergency power generation device 50 in this way. More specifically, the weather information providing device 90 obtains the weather information of the area or region where the emergency power generation device 50 exists from the individual point information where each emergency power generation device 50 is installed, and at that time The weighting is changed based on the information on the weather, temperature, humidity (relative humidity), wind direction, and wind speed in the corresponding area. The weighting is changed so that it becomes heavier as the operating environment of the emergency power generation apparatus 50 is severer, and so as to become lighter or not fluctuate as the operating environment becomes milder.

  For example, when the area where the specific emergency power generation device 50 exists is a plain part and the weather in the area is rain, the weight = 0.2 is increased. This is because the intrusion of rainwater is a concern. In addition, when the area where the specific emergency power generation device 50 exists is a coastal area, and there is a high probability that sea breeze is blowing to the emergency power generation apparatus 50 from the wind direction and wind speed of the area, the weight = 0.3 is increased. . This is because corrosion due to salt damage may progress. In addition, the temperature and the absolute humidity are also changed in weighting based on the evaluation together with the surrounding environment based on the environmental attribute information of the emergency power generator 50.

  Note that the above-described examples of weights by weighting are all set for convenience in order to technically explain the present embodiment. Actually, it is determined by specific characteristics of the casing 51, the engine 52, the generator 53, the cell motor 54, the battery 55, the control unit 56, etc. that constitute the emergency power generation device 50, and is determined by experiments, computer simulations, and the like. Predetermined.

  Next, an example of maintenance time notification processing by the maintenance information providing apparatus 10 will be described with reference to FIGS. 3 and 4. 3 and 4 are flowcharts showing the flow of the maintenance time notification process executed by the maintenance information providing apparatus 10. The flowchart shown in FIG. 4 is a flowchart of a modified example of the process shown in FIG. A maintenance time notification program that enables each of these processes is stored in the memory or the hard disk 13 constituting the main body 11 of the maintenance information providing apparatus 10.

  The maintenance time notification process shown in FIG. 3 is executed, for example, every predetermined time (for example, 6 hours). In the maintenance time notification process, first, a predetermined initialization process is performed in step S101. In this process, for example, the target number associated with the identifier (ID) assigned to each emergency power generator 50 is set to “001”, or the output flag described later is turned off (value “0”). Set or do. The target number is assigned to a plurality of emergency power generation devices 50 managed by the maintenance information providing device 10. For example, the maintenance information providing device 10 manages 20 emergency power generation devices 50. If it is, “001” to “020” are assigned.

  In step S103, weather information acquisition processing is performed. In this process, weather information is acquired via the Internet 100. As the weather information, for example, there is information distributed from a weather information providing apparatus 90 possessed by a weather information provider such as the Meteorological Agency or a private weather information provider. In the present embodiment, instead of acquiring weather information nationwide, for example, weather information providing device is used for pre-registered local or regional weather information based on individual point information where each emergency power generation device 50 is installed. 90. The acquired weather information is associated with the target number assigned to each emergency power generator 50. Thereby, the weather information of the area etc. where each emergency power generation device 50 is installed is associated with the target number of the corresponding emergency power generation device 50.

  In step S105, threshold information etc. acquisition processing is performed. Steps S105 to S111 are information processing performed for a specific emergency power generator 50 corresponding to the target number. Here, the emergency power generator 50 corresponding to the target number “001” will be described as an example. In step S <b> 105, information on a predetermined threshold value, parameter value, and weight set in advance for the emergency power generation device 50 with the target number “001” is acquired from the hard disk 13.

  In step S107, a weight change process is performed. This process is based on the weather information acquired in step S103, based on the information on the location of the emergency power generation device 50 having the target number “001” or the local weather, temperature, humidity (relative humidity), wind direction, and wind speed. Change the weight. As described above, the weighting is changed so that the operating environment of the emergency power generator 50 becomes heavier as the operating environment is severer, and the operating environment becomes milder or lighter as the operating environment is milder.

  In step S109, parameter value update processing is performed. In this process, the parameter value is updated with the passage of time since the previous execution. In other words, the parameter value corresponding to the emergency power generation apparatus 50 with the target number “001” is added with the addition value corresponding to the elapsed time (for example, 6 hours) from the previous execution multiplied by the “weight”. This “weight” is based on the weighting changed in step S107. The parameter value after the addition calculation is stored by being overwritten on the parameter value before update stored in the hard disk 13 corresponding to the emergency power generation apparatus 50 having the target number “001”.

  In step S111, a process for determining whether or not the updated parameter value exceeds the threshold value is performed. That is, the parameter value updated in step S109 is compared with a predetermined threshold value corresponding to the emergency power generation device 50 having the target number “001”. If the parameter value exceeds the threshold value (S111; Yes) Since it is time to perform maintenance work on the emergency power generator 50, the output flag is set to ON in the next step S113. On the other hand, when the parameter value does not exceed the threshold value (S111; No), the time for performing the maintenance work for the emergency power generation apparatus 50 has not yet arrived, so the next step S113 is skipped. Then, the process proceeds to step S115.

  The output flag is provided to determine whether or not to be the target of the arrival information output process in step S119. In step S119, the output number of the target number for which this output flag is on (value “1”) is provided. The maintenance power arrival information is output for the emergency power generator 50. In step S113, the output flag of the target number determined that the parameter value exceeds the threshold value in step S111 is set to ON (value “1”).

  In step S115, a target number update process is performed. That is, the target number for specifying the emergency power generator 50 is updated to the following. In the previous example, the target number is updated from “001” to “002”. The largest target number is also updated to the next number. In the previous example, since there are 20 emergency power generation devices 50 managed by the maintenance information providing device 10, the largest target number is “020”, but this is updated to “021”. Thereby, it is possible to determine whether all objects have been confirmed in the next step S117.

  In step S117, based on the target number updated in step S115, whether or not each process from step S105 to step S111 has been executed for all emergency power generation devices 50 managed by the maintenance information providing apparatus 10 is performed. Judgment is made. That is, it is determined whether or not the target number updated in step S115 exceeds the largest target number. In the previous example, when the target number exceeds “020” (S117; Yes), all the targets are confirmed, and when it does not exceed (S117; No), the unconfirmed emergency power generator 50 Will exist. If all the objects have been confirmed (S117; Yes), the process proceeds to the next step S119. If all objects have not been confirmed (S117; No), the process returns to step S105. Thereby, each process from step S105 to step S111 with respect to the next emergency electric power generating apparatus 50 is performed.

  In step S119, arrival information output processing is performed. In this process, as described above, the arrival information of the maintenance time is output for the emergency power generator 50 of the target number whose output flag is on (value “1”). The arrival information is output on the display 12 in a predetermined display format, for example. You may print with the printer 15 with a predetermined printing format.

  In the maintenance time notification process shown in FIG. 3, only weather information is acquired from the weather information providing device 90 via the Internet 100, and data and the like are obtained from each emergency power generator 50 connected to the Internet 100. Not acquired. Thereby, even when the emergency power generation device 50 is not connected to the Internet 100, the emergency power generation device whose operating environment is severer than the case where the operating environment is mild by the above-described maintenance time notification process. It is possible to provide the arrival information of the maintenance time as early as 50, and it is possible to provide the arrival information of the maintenance time including the change in the operating environment of the emergency power generator 50 that is influenced by the weather conditions of the installation location. .

  Here, a modified example of the maintenance time notification process modified so as to acquire data relating to device attribute information from each emergency power generation device 50 connected to the Internet 100 will be described with reference to FIG. In addition, about the process step substantially the same as FIG. 3, the same code | symbol is attached | subjected in FIG.

  As shown in FIG. 4, in the maintenance time notification process of the modified example, the current information acquisition process in step S104 is performed after the weather information acquisition process in step S103, and the current information of each emergency power generator 50 acquired in step S104 is displayed. Based on the data relating to the device attribute information, the weight change processing in step S107 is performed. These two processing steps are different from the maintenance time notification processing described with reference to FIG. In FIG. 4, the processing step (S104) added by the modified example is represented by a thick line frame.

  That is, in the current information acquisition process in step S104, as described above, the sensor provided in each emergency power generation device 50, for example, the voltage sensor that measures the output voltage of the battery 55, the temperature in the housing 51 is measured. Temperature sensor, humidity sensor that measures the humidity in the casing 51, liquid sensor that can measure the amount of cooling water in the radiator, and liquid level that can measure the liquid level (liquid amount) of the fuel amount in the fuel tank 57 The amount of data transmitted to the maintenance information providing apparatus 10 via the Internet 100 is acquired from a sensor, a liquid sensor capable of measuring the amount of engine oil, and the like. Each acquired data is temporarily stored in the memory of the main body 11 or the hard disk 13 in association with the target number or identifier (ID) of the emergency power generator 50.

  Thereby, since the data regarding apparatus attribute information is obtained from each emergency power generation apparatus 50, based on any one or more of these data, in the weight change process by step S107, it is based on the weather information mentioned above. In addition to changing the weighting, the weighting is further changed based on the device attribute information of the emergency power generator 50 corresponding to the target number. For example, when the output voltage of the battery 55 is lower than the rated voltage, the temperature in the housing 51 exceeds the specified temperature during normal time, or the humidity in the housing 51 is normal during the normal time. When the specified temperature is exceeded, or when the remaining amount of fuel in the fuel tank 57 is less than the specified remaining amount, it is determined that the operating environment of the emergency power generator 50 is severe, and an appropriate weight is assigned. If none of these cases apply, the weighting is not changed based on the device attribute information.

  As described above, in the maintenance time notification process of the modified example, data related to the device attribute information is acquired from the emergency power generation device 50 in step S104, and the weight is changed based on the data in step S107. As a result, since the weight of the weight is set based on the data related to the device attribute information unique to the emergency power generation device 50 to be subjected to the maintenance work, the maintenance time that can be different for each emergency power generation device 50 has arrived. Information can be provided.

  Note that the current information acquisition process in step S104 shown in FIG. 4 may be executed after step S105, for example, before the weight change process (S107). In the current information acquisition process in this case, in order to acquire the data related to the device attribute information for the target emergency power generation device 50, the main body is associated with each acquired data in association with the target number or the like as compared with the case where it is executed in step S104. There is no need to temporarily store the data in the memory of the unit 11 or the hard disk 13. However, every time the processing steps from step S105 to step S111 are executed, it is necessary to acquire data related to the device attribute information for the corresponding emergency power generation device 50.

  As described above, in the maintenance information providing apparatus 10 according to the present embodiment, with the passage of time according to the weighting set so that the operating environment of the emergency power generation apparatus 50 is heavier and milder as the operating environment is severer. When the increasing parameter value exceeds a threshold set in advance based on the device attribute information (S111; Yes), the arrival information of the maintenance time is output to the display 12 and the printer 15 (S119). As a result, the parameter value exceeds the threshold earlier and the information on the arrival of the maintenance time is output to the display 12 or the like as the operating environment is severer than in the case where the operating environment of the emergency power generator 50 is mild. In addition, since the weight varies depending on the weather information of the region or the region where the emergency power generation device 50 is installed (S107), the weighting of the emergency power generation device 50 depends on the weather conditions of the installation location. It is possible to output information on the arrival of maintenance time, including changes in the operating environment. Accordingly, it is possible to provide arrival information at an appropriate maintenance time.

  Further, in the maintenance information providing apparatus 10 according to the present embodiment, the weight of the weight is set based on the data related to the apparatus attribute information unique to the emergency power generation apparatus 50 to be subjected to the maintenance work (S107 shown in FIG. 4). . Accordingly, it is possible to output the arrival information of the maintenance time that can be different for each of the emergency power generation devices 50. Accordingly, it is possible to provide accurate and appropriate arrival information on the maintenance time.

  Furthermore, in the maintenance information providing apparatus 10 according to the present embodiment, the arrival information of the maintenance time is displayed on the display 12 or the printer 15 at the longest at the time of the legal inspection according to a predetermined law or the like and the preset periodic inspection. Therefore, the maintenance time of the emergency power generation apparatus 50 can be managed without the need for separately checking the inspection time. Therefore, it is possible to provide information on the arrival of an appropriate maintenance time including legal inspection.

  In the above-described embodiment, the emergency power generation device 50 has been described as an example of the equipment device. However, for example, the same technology as described above is applied to the uninterruptible power supply device 60 illustrated in FIG. Effects and effects can be obtained. That is, the uninterruptible power supply 60 includes a casing 61, a transformer 62, a converter 63, a battery 64, an inverter 65, a voltage sensor 66, a control unit 67, and a communication device 69. The transformer 62 and the like are included in the casing 61. For example, it is installed in a high place such as a utility pole or a rooftop of a building.

  The control unit 67 monitors the voltage of the commercial power input to the input terminal IN by the voltage sensor 66, and when the commercial power supply is interrupted, that is, when a power failure occurs, the control unit 67 activates the inverter 65 and supplies it from the battery 64. The direct current power is boosted to a voltage similar to that of commercial power, converted into alternating current power, and output to the output terminal OUT. During normal times, AC power input from the input terminal IN is output to the output terminal OUT via the transformer 62, and the battery 63 is charged by performing step-down conversion to DC power suitable for charging the battery 66 by the converter 63.

  The device attribute information can be conceptualized even for the uninterruptible power supply 60 configured in this way. That is, the paint color of the casing 61 and the presence / absence of measures such as waterproof, dustproof, rustproof, and vibration proof correspond to the device attribute information. The thickness of the metal plate constituting the housing 61 also corresponds to the device attribute information. Each type of the transformer 62 and the battery 64 also corresponds to device attribute information. Furthermore, the total number of electronic components constituting the converter 63, the inverter 65, and the control unit 67 that have a heat-resistant temperature of 85 ° C. or lower (for example, electrolytic capacitors) and components that can be mechanically electrically connected such as connectors. The number of electrodes and the like also correspond to the device attribute information. In addition, with respect to the environmental attribute information set in advance with respect to the surrounding environment of the place where the uninterruptible power supply 60 is installed, for example, the installation location of the uninterruptible power supply 60 and the like are the same as the emergency power generation apparatus 50 described above. The weighting applied to the parameter values can be set based on the environmental attribute information. Thereby, it is possible to apply the maintenance time notification process (FIGS. 3 and 4) by the maintenance information providing apparatus 10 as in the case of the emergency power generation apparatus 50 described above, and the technical operations and effects similar to those described above. Can be obtained.

  Moreover, although the diesel engine was illustrated and demonstrated in the embodiment mentioned above as the engine 52 which comprises the emergency power generation apparatus 50, the engine may be a gasoline engine. In the case of a gasoline engine, a preheating heater is unnecessary as an auxiliary machine.

  Furthermore, in the above-described embodiment, the maintenance time notification process by the maintenance information providing apparatus 10 is executed every predetermined time (for example, 6 hours), but may be executed once a day, for example. In this case, since the elapsed time from the previous execution time is 24 hours, in the parameter value update process in step S109, it is necessary to add to the parameter value a value obtained by multiplying the added value corresponding to 24 hours by the “weight”. is there.

  In the above-described embodiment, the case where the casings 51 and 61 of the emergency power generation apparatus 50 and the uninterruptible power supply 60 are made of metal has been described as an example. Even in the case of being made of synthetic resin such as, the housing structure can be conceptualized as device attribute information. In this case, when ultraviolet rays or acid rain affects the degree of deterioration or corrosion of the casing, and rainwater or dust can enter from a location where cracks or corrosion has occurred, the engine 52 and the inverter 65 housed in the casing. It affects the degree of occurrence of failures such as.

  In the above-described embodiment, the initial value of the parameter value is set so that the parameter value can exceed a predetermined threshold at the time of legal inspection or periodic inspection when it increases by a certain value as time passes. If the weighting is continuously applied to the parameter value (when the operating environment is the mildest), it may be set so that the predetermined threshold value can be exceeded after a predetermined time, for example, two years later. Thereby, the longest maintenance time can be arbitrarily set regardless of the time of legal inspection or the like.
