Description

  The present invention relates to a control system for an emergency power generator that remotely controls the operation of a generator driving engine provided in the emergency power generator.

  An emergency power generator supplies power to a load by operating a generator using an engine in an emergency, such as when a commercial power supply is interrupted. Therefore, it is desirable that the time required from the occurrence of a power failure to the resumption of power supply is as short as possible. However, startup of an internal combustion engine such as a diesel or gasoline engine takes some time, and more time is required until the output voltage or the phase of the AC waveform is stabilized after the generator starts rotating by the engine.

  The standard for private power generation facilities based on the Fire Service Law enforcement regulations stipulates that “the time required for establishing and turning on the voltage after a power failure occurs within 40 seconds” is stipulated. Therefore, emergency power generators for buildings and commercial facilities will start supplying power within this time. Some specifications start power transmission within 10 seconds, but it is necessary to wait about 10 seconds after a power failure. During this time, the power failure cannot be avoided. Although there are prior arts disclosed in Patent Documents 1 and 2 below as techniques related to quick start-up of an emergency power generator, the above-mentioned problems are solved in cases where both the engine and the generator are started. I can't do it.

The control system for an emergency power generator according to claim 1 acquires disaster information including various power failure factor information by the information acquisition unit, and the disaster information and point information where a plurality of emergency power generators are installed. On the basis of (stored in the installation point storage unit) , the power failure prediction unit predicts the occurrence of a power failure of the commercial power supply in each region where a plurality of emergency power generation devices are installed . And when the occurrence of a power failure is predicted by the power failure prediction unit, even if a power failure does not occur, a specific emergency power generator installed in the power failure prediction region where the start control unit is expected to generate a power failure Is determined based on the power failure factor information, and engine operation is started. As a result, the specific emergency power generation apparatus starts the operation of the engine before the occurrence of a power failure. Therefore, when the power failure occurs, the engine is already activated and the generator is driven. Therefore, even if it takes time until the generator starts rotating from the start of the engine and the phase of the output voltage and AC waveform stabilizes, it is possible to complete the series of sequences before the occurrence of a power failure. .

In addition, if the occurrence of a power outage is not predicted in the power outage prediction area based on the disaster information newly acquired by the information acquisition unit or other information after the start of the engine operation by the start control unit, a specific emergency The stop control unit stops the engine operation in the power generator. After the start of the operation of the engine by the start control unit, the engine wastes fuel if the operation is continued as it is even though there is no power outage in the power outage prediction area . In some cases, there may be a shortage of fuel required for continuous operation within the time specified in the specification. For this reason, after the engine is started, when the occurrence of a power failure is not predicted in the power failure prediction area, it is possible to avoid unnecessary operation of the engine at normal time by stopping the operation of the engine.

The machine is driven. Therefore, even if it takes time until the generator starts rotating from the start of the engine and the phase of the output voltage and AC waveform stabilizes, it is possible to complete the series of sequences before the occurrence of a power failure. . Therefore, power can be supplied in a short time when a power failure occurs, and the power failure period can be shortened. In addition, when the occurrence of a power failure is not predicted in the power failure prediction area after the engine is started, the operation of the engine is stopped, so that it is possible to avoid unnecessary operation of the engine at the normal time. Therefore, waste of fuel can be avoided and fuel that can be used in an emergency can be secured.

  Moreover, in the control system of the emergency power generation device of the present invention, it is possible to grasp that there is an abnormality in the emergency power generation device other than regular or irregular inspection and maintenance. Therefore, since it turns out that the said emergency power generation device does not operate | move normally, the malfunctioning in an emergency can be avoided by a repair response.

Furthermore, the control system for an emergency power generator according to the present invention can grasp the remaining amount of fuel in the fuel tank. Therefore, it is possible to determine whether or not sufficient fuel remains at the next start-up of the emergency power generation apparatus.

Reference numeral 13 shown in FIG. 1 denotes a control unit.

  FIG. 1 is a block diagram showing an example of the configuration of the control terminal device 20, so the configuration of the control terminal device 20 will be described first. The control terminal device 20 is an information processing device (computer) that can execute each control program of the control system to be described later. For example, a general-purpose personal computer (hereinafter referred to as “personal computer”) is used. The personal computer is mainly composed of a main body 21, a display 22, a hard disk 23, and the like.

  The main body 21 is a main body of a computer that includes a CPU, a memory, an input / output interface, and the like.

Therefore, the information communication line network constituting the present control system may be a closed communication network provided by a communication carrier, a dedicated line, a public line network, or the like.

  Next, the configuration of the emergency power generator 10 will be described with reference to FIG. FIG. 2 is a block diagram of the emergency power generator 10 constituting the present control system. The emergency power generator 10 mainly includes an engine (ENG) 11, a generator (GEN) 12, a control unit (CNT) 13, a battery (BAT) 14, a cell motor (CM) 15, a fuel tank 16, and the like. In the event of an emergency, the generator 11 is operated using the engine 11 to supply power to the load. 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 engine 11 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 12. In this embodiment, a diesel engine is used. Therefore, in addition to the cell motor 15 that controls the start of the engine 11 and the fuel pump 17 that controls the supply of the fuel F from the fuel tank 16 to the engine 11, a preheating heater, a stop solenoid, and the like (not shown) are used as auxiliary machinery for the engine 11. Is provided.

  The generator 12 is a power device that generates AC power by converting rotational energy from the engine 11 into electrical energy by electromagnetic induction, and the AC power output from the generator 12 is an emergency power source. Although not shown, the emergency power generation apparatus 10 is connected to a load transmission line for transmitting the generated emergency power.

  The control unit 13 is a computer device that controls various operating states such as starting and stopping of the engine 11 and various controls associated therewith. The control unit 13 includes a CPU, a memory, an EEPROM, an input / output interface, an operation panel, a communication interface, and the like (not shown) to which a cell motor 15, a fuel pump 17, a preheating heater, a stop solenoid, and the like are connected.

The control unit 13 is also input with voltage information of the commercial power supply, and is configured to detect the occurrence of a power failure of the commercial power supply.

  The battery 14 is a rechargeable secondary battery that can generate a predetermined DC voltage (for example, 24 V), and is electrically connected to the control unit 13 in addition to the cell motor 15, the fuel pump 17, and the preheating heater. ing. As a result, the engine 11 can be started and the control unit 13 can be driven without receiving power supply from the outside.

  The communication device 19 enables the emergency power generation device 10 to be connected to the Internet 100 and is the same as the communication device 29 constituting the control terminal device 20 described above. Therefore, the communication device 19 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 10 is assigned in advance to the communication device 19 provided in the emergency power generation device 10, and the control terminal device 20 uses a plurality of identifiers based on this identifier. A specific emergency power generator 10 is identified from the emergency power generator 10. The identifier is, for example, an IP address or a MAC address.

  The emergency power generator 10 of the present embodiment includes a plurality of sensors. One of them is a voltage sensor 18 a that measures an AC voltage output from the generator 12. The output of the voltage sensor 18 a is connected to the control unit 13, and the control unit 13 can acquire information on the output voltage of the generator 12, that is, voltage information on the emergency power supply supplied by the emergency power generator 10. It is configured as follows. In addition to this, the emergency power generation apparatus 10 includes a flow rate sensor 18b that measures the flow rate of the fuel F supplied from the fuel tank 16 to the engine 11 via the fuel pump 17, or fuel stored in the fuel tank 16. A liquid level sensor 18c capable of measuring an amount of liquid level is provided. These sensors 18b and 18c each measure data necessary for obtaining the remaining amount of fuel F, as will be described later. Therefore, it is not necessary to provide both of these, and it is sufficient if either one is provided.

  By configuring the emergency power generation apparatus 10 in this way, the control unit 13 drives the cell motor 15, the fuel pump 17, the preheating heater and the like when starting the engine 11, and stops the engine 11 when stopping the engine 11. And the fuel pump 17 is stopped. The engine 11 can be started and stopped via the operation panel of the control unit 13, and in this embodiment, the engine 11 start command, stop command, and the like input from the Internet 100 via the communication device 19 are used. This control command can also be used. Further, in the present embodiment, each data acquired or measured by the various sensors 18a to 18c such as the voltage sensor 18a is displayed on the display device of the operation panel or given to the emergency power generation device 10. The identifier is sent to the control terminal device 20 via the communication device 19.

Next, an example of remote control of the emergency power generator 10 by the control terminal device 20 will be described with reference to FIGS. FIGS. 3 and 4 are flowcharts showing the flow of the predictive startup process (FIG. 3) and the post-predictive stop process (FIG. 4) as the control process of the engine 11 executed by the control terminal device 20. . 6 and 7 are flowcharts showing the flows of the monitoring process after the predicted activation (FIG. 6) and the fuel amount monitoring process (FIG. 7) as the monitoring process of the engine 11 executed by the control terminal device 20. Has been. FIG. 5 is an explanatory diagram showing the concept of each area where the emergency power generation apparatus 10 is installed. Each control program which enables each of these processes is stored in the memory or the hard disk 23 constituting the main body portion 21 of the controlling device 20.

  The predictive start-up process shown in FIG. 3 starts operation of the engine 11 of the corresponding emergency power generation apparatus 10 by remote control even if no power outage has occurred at the time of occurrence of a power outage. In principle, it is repeatedly executed every predetermined time (for example, every 5 minutes, 10 minutes, or 30 minutes). However, when the later-described re-stop flag is set to ON, the operation of the engine 11 is forcibly stopped by the stop process after the predicted start shown in FIG. However, this prediction activation process is not executed. First, in the prediction activation process, disaster information is acquired in step S101. The disaster information is, for example, information that can be acquired from each business 50 to 90 via the Internet 100, and includes weather information, terrestrial information, sea state information, fire information, and scheduled power outage information. Each piece of information includes area information indicating the corresponding area.

  The weather information is distributed from, for example, a weather information provider 50 such as the Japan Meteorological Agency or a private weather information provider, and information that may cause a power outage includes thunder clouds, typhoons, tornadoes, gusts, precipitation, snowfall. Examples are related to avalanches, tsunamis, storm surges, and the like. The geological information relates to earthquakes, volcanic phenomena, and various phenomena in the ground and underground that are closely related to the weather. These are also the geological information providers 60 such as the Meteorological Agency and private weather information providers. Delivered from. The oceanographic information is information on natural phenomena that occur in the sea and is distributed from the oceanographic information provider 70. Tsunamis and storm surges that can cause power outages are included in both oceanographic information and weather information. It is.

  Fire information mainly relates to the occurrence of fires that can cause power outages in buildings, forests, etc., and is distributed by local public organizations, their firefighting headquarters, fire departments, or fire information providers 80 such as the Tokyo Fire Department. The The fire information may include part of weather information such as humidity, wind direction, and wind force assuming fire spread. Further, the scheduled power outage information is distributed from the commercial power supplier 90 that supplies the commercial power, and notifies in advance of the stop of the commercial power supply such as the planned power outage. In addition to the information obtained through the Internet 100, the disaster information may be acquired through a receiving device capable of receiving broadcast waves transmitted from the Japan Broadcasting Corporation or a private broadcasting station, for example. Also, for example, it may be acquired directly or indirectly from a national instantaneous warning system (J-ALERT).

  In step S103, based on the disaster information acquired in step S101, it is determined whether or not information associated with a power failure, that is, power failure factor information is included therein. For example, meteorological information, terrestrial information and marine information distributed from the Japan Meteorological Agency or private weather information providers, etc. due to lightning of substations and power transmission towers, collapse or inundation of facilities, disconnection of transmission lines, etc. If information about a power outage, such as thunderclouds, typhoons, wind damage, water damage, snow damage, earthquakes, tsunamis, etc., is included, it is determined that there is a power outage factor (S103; Yes), and the following step The process proceeds to S105. Since the fire information and the scheduled power outage information are generally due to a power outage, when these are acquired, the process proceeds to step S105. If the disaster information does not include information resulting from a power outage, for example, if the risk of wind damage or water damage is expected to be extremely low from the acquired wind speed and precipitation information, It is determined that there is no occurrence, that is, there is no cause of power failure (S103; No), and this predictive activation process is terminated.

  In subsequent step S105, an occurrence area specifying process is performed. In this process, based on the disaster information acquired in step S101, the area where the disaster occurs is specified from the area information indicating the corresponding area included in the disaster information. The area is specified by, for example, a wide area such as the Kanto region or the Chubu region, a middle region such as a prefecture unit, or a local area that is detailed to a municipality. In addition, what was divided for every electric power supply jurisdiction area by the commercial electric power supply provider 90 may be used. For example, in the example illustrated in FIG. 5, the area is divided into three areas, an α area, a β area, and a γ area, and a plurality of emergency power generation apparatuses 10 indicated by white circles exist in each area. Note that <α01>, <β01>, and the like shown below in the white circle are examples of identifiers.

In the next step S107, processing for determining whether or not the emergency power generation apparatus 10 is present in the area specified in step S105 is performed. That is, for example, whether or not the emergency power generation device 10 is installed in an area where a disaster such as thundercloud, typhoon, wind damage, water damage may occur (or occurs) is stored in the control terminal device 20. Judgment is made based on information (point information) of individual points where the emergency power generation apparatus 10 is installed. If the emergency power generation apparatus 10 is present in the area (S107; Yes), the process proceeds to the subsequent step S109 to perform disaster-specific determination processing. If the emergency power generation device 10 does not exist in the area (S107; No), it is determined that no power failure occurs in the area where the emergency power generation device 10 remotely controlled by the control terminal device 20 is installed. This prediction start processing is terminated.

  In step S109, an activation target specifying process is performed. In this process, the emergency power generator 10 that starts the engine 11 is specified for each type of disaster. That is, the disaster information acquired in step S101 includes various types of power failure factors. Therefore, in this step S109, among the emergency power generation apparatuses 10 installed in the same area, the emergency power generation apparatus 10 that starts the engine 11 is specified according to the type of disaster information.

  For example, when the disaster information is a thundercloud, the emergency power generation apparatus 10 that starts the engine 11 is specified based on the distance from the thundercloud or the lightning strike point. In the example shown in FIG. 5, thunderclouds (range colored in light ink) and lightning strike points (points marked with x) exist in the α region and the γ region. Therefore, among the emergency power generators 10 <α01> to <α07> and the emergency power generators 10 <γ01> to <γ04> installed in these areas, for example, a thundercloud or a plurality of lightning strikes has a radius of 10 km. Emergency power generators 10 <α01>, <α02>, <α03>, <α06>, <α07> and emergency power generators 10 <γ04> existing within the range are used as emergency power generators 10 for starting the engine 11. Identify.

  In addition, when the disaster information is a typhoon, the emergency power generation apparatus 10 that falls within a storm zone with a wind speed of 25 m / sec or more is activated as a target to be activated based on the typhoon size, atmospheric pressure, expected course, speed, and the like. Identify. If the disaster information is wind damage or water damage (or snow damage), the size of the approaching low pressure, atmospheric pressure, expected course, speed, etc., or the range of rain clouds (or snow clouds), rivers (or snow cover) that may overflow The emergency power generator 10 that starts the engine 11 is specified based on the position of a building or the like that may collapse due to a load.

  In addition, when the disaster information is an earthquake, the emergency power generation apparatus 10 existing in an area where a vibration with a seismic intensity of 5 or more is generated based on the magnitude (magnitude) of the earthquake, the position of the epicenter, etc. As specified. If the disaster information is a tsunami, based on the magnitude (magnitude) and position of the epicenter that causes the tsunami, for example, emergency power generation that exists in an area where a large tsunami with a wave height of 5 m or more is expected to arrive The device 10 is specified as a target for starting the engine 11. In order to specify the emergency power generation apparatus 10 due to an earthquake or tsunami, for example, an emergency earthquake warning based on a nationwide instantaneous warning system or a large tsunami warning may be used.

  In addition, when the disaster information is fire information, the emergency power generation apparatus 10 having a short distance is specified as a start target of the engine 11 based on the position and range of the fire site. Further, in the case of a large-scale fire, the emergency power generation device 10 existing within the estimated fire spread range is specified as a start target of the engine 11 based on the spread fire direction, the wind direction, and the like. When the disaster information is information on a planned power outage, the emergency power generation apparatus 10 existing in the planned power outage area is specified as a target for starting the engine 11 before the scheduled power outage time.

  In step S111, it is determined whether or not the emergency power generation device 10 has been specified as a start target of the engine 11 in step S109. If the emergency power generation device 10 specified in step S109 exists (S111; Yes). Then, the process proceeds to the next step S113, and remote control for starting the engine 11 is performed on the target emergency power generation apparatus 10. On the other hand, when such an emergency power generation device 10 has not been specified in step S109 (S111; No), there is no emergency power generation device 10 that should start the engine 11, and therefore this predictive activation process. Exit.

  In step S113, a process of sending a start command for starting the engine 11 is performed with respect to the “specific emergency power generation apparatus 10” specified in step S109. That is, an engine 11 start command is sent to the emergency power generation apparatus 10 in an area where a power failure is expected, along with an identifier for identifying the emergency power generation apparatus 10 via the Internet 100. Thereby, the “specific emergency power generation device 10” that has received the start command together with this identifier starts the engine 11.

  In the subsequent step S115, a flag ON setting process is performed. In this process, a state flag (hereinafter simply referred to as “flag”) provided for each of the plurality of emergency power generators 10 that can be remotely controlled by the control terminal device 20 is set to ON. The association between each emergency power generation apparatus 10 and the flag is performed by the identifier described above. When this flag is set to ON, it indicates that the emergency power generator 10 corresponding to the flag has been started. When this flag is set to OFF, it indicates that the emergency power generator 10 has been stopped. Show. In step S115, the flag corresponding to “specific emergency power generation apparatus 10” to which the start command is sent in step S113 is set to ON.

In step S117, a timer start process is performed. This timer is for a time meter and the time elapsed since the sending start command of the engine 11 in step S113, similarly to the flag, the control terminal apparatus 20 is the power generation device for a plurality of very capable of performing remote control 10 Are provided individually. Therefore, here, only the timer corresponding to the “specific emergency power generation apparatus 10” to which the start command for the engine 11 is sent in step S113 is started. When step S117 is completed, a series of main prediction activation processes are completed.

  As described above, in the predictive activation process of the present control system, the disaster information is acquired by the disaster information acquisition process (S101), and the occurrence of a power failure of the commercial power source is determined based on the disaster information. Predictions are made through the specific process (S105), the emergency power generator presence determination process (S107), and the activation target specific process (S109). And when generation | occurrence | production of a power failure is estimated and the starting object is specified (S111; Yes), even if a power failure does not generate | occur | produce, start command sending process (S113) with respect to this specific emergency power generation device 10 ) Is sent out to cause the specific emergency power generator 10 to start the operation of the engine 11. Thereby, since the operation of the engine 11 of the specific emergency power generation apparatus 10 is started before the occurrence of the power failure, the engine 11 is already activated and the generator 12 is driven when the power failure occurs. . Therefore, even if it takes time from the start of the engine 11 until the generator 12 starts rotating and the phase of the output voltage and AC waveform stabilizes, it is possible to complete the series of sequences before the occurrence of a power failure. become. Therefore, power can be supplied in a short time when a power failure occurs, and the power failure period can be shortened.

  Next, the stop process after the predicted activation will be described with reference to FIG. 4 is executed after the predicted activation process shown in FIG. 3 is completed, and when the operation of the engine 11 of the emergency power generation apparatus 10 once activated satisfies a predetermined condition. To stop. That is, after starting the engine 11, (1) when the occurrence of a power outage is not predicted by newly acquired disaster information, or (2) when the power outage does not occur after a predetermined time has elapsed, the engine 11 Stop operation. Thereby, waste of the fuel F is suppressed.

  First, in the prediction start stop process, a process of reading a flag is performed in step S201. This flag is described in step S115 of the predictive activation process, and is set to ON when there is an emergency power generation apparatus 10 that has received the activation command by the predictive activation process. Therefore, it is determined whether or not there is a flag set to ON in the subsequent step S203. If there is an ON flag (S203; Yes), the process proceeds to the next step S205. On the other hand, when there is no ON flag (S203; No), there is no emergency power generation apparatus 10 in which the engine 11 is activated, and thus the stop process after the predicted activation ends.

  In steps S205, S207, S209, and S211, disaster information is acquired in order to confirm the first condition (condition (1)) of the “predetermined conditions”, and step S101 shown in FIG. , S103, S105, and S107, respectively. That is, the presence or absence of a power failure factor is determined based on the disaster information acquired from each business operator 50 to 90, and if there is a power failure factor (S207; Yes), the region where the power failure occurs is specified (S209) and the region. It is determined whether or not the emergency power generation device 10 exists in the device (S211). When the emergency power generation device 10 exists in the area (S211; Yes), the timer reading process in step S213 is performed. Further, when there is no cause of power failure (S207; No) or when the emergency power generation apparatus 10 does not exist in the area (S211; No), (1) the occurrence of a power failure is predicted by newly acquired disaster information. Since it corresponds to the case where it is not performed, the operation of the engine 11 of the emergency power generation apparatus 10 that has been started is temporarily stopped. That is, the process proceeds to step S221, and stop command transmission processing is performed.

  If it is determined in step S211 that the emergency power generation apparatus 10 is present in the area (S211; Yes), the process related to the second condition (condition (2)) of the "predetermined conditions" (S213) , S 215, S 217, S 219) and the processes after step S 221 may be configured to end the stop process after the prediction activation. As a result, as long as the emergency power generation device 10 exists in the area and the fuel F remains in the fuel tank 16, the operation of the engine 11 is continuously performed. Therefore, in an environment where the remaining amount of fuel F does not matter (when a large fuel tank 16 that can be operated for a long time is provided, or when a fuel F replenishment system is in place), a power failure occurs. Be prepared for the factors. Further, when it is determined in step S211 that the emergency power generation apparatus 10 does not exist in the area (S211; No), a predetermined time (for example, 10 minutes or 30 minutes) has elapsed without immediately proceeding to step S221. After that, it may be configured to proceed to step S221.

  The subsequent timer reading process (S213), predetermined time lapse determination process (S215), power failure information acquisition process (S217), and power failure determination process (S219) are the second condition (of (2)) of the “predetermined conditions”. To confirm the condition). That is, after the engine 11 is started by the predictive activation process of FIG. 3, the operation of the engine 11 leads to wasteful consumption of the fuel F if no power failure occurs even after a predetermined time has elapsed. Therefore, when the timer whose timing is started in step S117 of the predictive activation process of FIG. 3 is read and the timer value exceeds a predetermined time (for example, 10 minutes) (S215; Yes), the emergency power generator 10 Get power outage information. And when the power failure of commercial power has not occurred (S219; No), it shifts to Step S221 and sends a stop command to the emergency power generator 10. On the other hand, when the timer value does not exceed a predetermined time (for example, 10 minutes) (S215; No) or when a commercial power failure occurs (S219; Yes), the operation of the engine 11 is scheduled. In order to continue the operation as it is, the stop process after the start of the prediction is terminated.

Step S221 is a process of stopping the engine 11 of the emergency power generation apparatus 10 that satisfies the “predetermined condition” (the condition (1) or (2)). Send a stop command to stop operation. The corresponding emergency power generation apparatus 10 is identified by the above-mentioned identifier sent together with the stop command. Thereby, the corresponding emergency power generating apparatus 10 that has received the start command together with this identifier stops the operation of the engine 11. In the subsequent step S223, a flag off setting process is performed. It sets the flag corresponding to the step S223 emergency power generator 10 of the corresponding a stop command is sent by on. In addition, a timer stop process is performed in step S225. Accordingly, it stops the timer corresponding to the emergency power generator 10 of the corresponding a stop command is sent. When step S225 ends, a series of post-start prediction stop processing is completed.

  If it is determined in step S219 that a commercial power failure has occurred (S219; Yes), the re-stop flag is turned on in the process from the stop command transmission process (S221) to the timer stop process (S225). You may comprise so that it may set. This re-stop flag is a flag provided separately from the “state flag” described above, and the engine 11 once started by the prediction start process (FIG. 3) is stopped again by the stop process after the predicted start. This is a flag for storing the effect. Therefore, when this re-stop flag is set to ON, as described above, even if the timing for executing the predicted activation process shown in FIG. The power generation device 10 continues to stop. As a result, the execution timing of the predicted activation process that occurs every predetermined time arrives and the engine 11 is not restarted many times.

  In this way, in the stop process after the predicted start-up of this control system, after the start command is sent by the start command sending process (S113) and the engine 11 is started, it is newly acquired by the disaster information acquisition process (S205). If a power outage is not predicted based on disaster information (condition (1) above) or other information (condition (2) above) (S207; No, S211; No or S219; No), stop A stop command is sent to the corresponding emergency power generator 10 by the command sending process (S221), and the operation of the engine 11 is stopped. Thus, after the operation of the engine 11 is started, if the operation is continued as it is even though no power failure occurs, the engine 11 can be prevented from wasting the fuel F. It is possible to avoid a situation where the fuel F required for continuous operation within the time specified above is insufficient. Therefore, when the occurrence of a power failure is not predicted after the engine 11 is started, it is possible to avoid unnecessary operation of the engine 11 at normal time by stopping the operation of the engine 11. Therefore, waste of the fuel F can be avoided and the fuel F that can be used in an emergency can be secured.

  By the way, even if the start command is sent, the engine 11 of the emergency power generator 10 does not always start. That is, when the engine 11 itself is out of order, or when accessories such as the battery 14, the cell motor 15 and the fuel pump 17 are out of order for starting the engine 11, or when the fuel F in the fuel tank 16 is out of order. If the fuel is deteriorated or the fuel F does not remain, the engine 11 does not start.

  For this reason, in the present embodiment, the operation state of the engine 11 after the start command is sent is monitored by executing the predicted post-start monitor process shown in FIG. Note that it is more effective to execute this process after the predicted activation process shown in FIG. 3 is completed. However, in the example of the process shown in FIG. 6, the execution timing is arbitrary, and only after the predicted activation process is completed. I can't. FIG. 6 is a flowchart showing the flow of the monitoring process after the prediction activation executed by the control terminal device 20.

  As shown in FIG. 6, in the monitor process after the prediction activation, first, a flag reading process is performed in step S301. This flag is a flag described so far, and is individually provided for a plurality of emergency power generators 10 that can be remotely controlled by the control terminal device 20. In step S303, it is determined whether or not there is a flag that is set to ON. If there is a flag that is set to ON (S303; Yes), the engine 11 is started in response to the start command. Since the power generation device 10 exists, operation information is acquired from the emergency power generation device 10 in the subsequent step S305. The emergency power generation device 10 is specified by an identifier associated with the flag. In the present embodiment, the output voltage of the generator 12 is acquired by the voltage sensor 18a.

  The operation information of the engine 11 of the emergency power generation device 10 acquired in step S305 is displayed on the display 22 of the control terminal device 20 in a predetermined format in step S307, and then it is determined whether or not the operation is being performed in step S309. Is done. In the present embodiment, it is determined whether or not the engine 11 is operating normally based on the output voltage information acquired by the voltage sensor 18a, that is, the voltage information of the emergency power supply supplied by the emergency power generation device 10. When the voltage of the emergency power supply is significantly lower than the rated voltage in the specification, or when no voltage is output, there is a high probability that the engine 11 is not operating normally. In such a case (S309; No), an indication that there is an abnormality in the engine 11 is output to the display 22 or the printer 25 by the engine abnormality display process in the subsequent step S311, and further, the log is recorded by the abnormality information recording process in step S313. It is recorded in a file and saved on the hard disk 23. An identifier or a unique name that can identify the corresponding emergency power generation apparatus 10 is added to such display and output.

  On the other hand, when there is no flag set to ON by step S303 (S303; No), or when it is determined that the engine 11 is operating by step S309 (S309; Yes), the start command It is highly possible that the emergency power generator 10 is operating without any problem after the transmission. That is, since the operation of the engine 11 is normal and there is no abnormality in the emergency power generation device 10, the monitoring process after this prediction activation is completed. Also, when the abnormality information recording process in step S313 is completed, a series of post-predictive activation monitoring processes are completed.

  As described above, in the monitoring process after predictive activation of the present control system, the operation information of the engine 11 is acquired by the operation information acquisition process (S305), and the occurrence of a power failure is predicted based on the acquired operation information. When it is found that the engine 11 that should have started operation is not started (S309; No), abnormality information indicating that the emergency power generation apparatus 10 is abnormal is displayed by the engine abnormality display process (S311). The data is output to the display 22 and the printer 25 of the control terminal device 20. Thereby, it can be grasped that there is an abnormality in the emergency power generation apparatus 10 other than regular or irregular inspection and maintenance. Therefore, since it turns out that the said emergency power generation apparatus 10 does not operate | move normally, the malfunctioning in an emergency can be avoided by a repair response.

  As described above, in the present embodiment, the occurrence of a power failure is predicted, and even if a power failure does not occur, the start command is sent to the specific emergency power generation apparatus 10 to start the engine 11. Therefore, when the occurrence of a power failure is lost and the engine 11 is no longer started, the fuel F consumed by starting the engine 11 or operating for a predetermined time is unnecessarily reduced. Further, even when the occurrence of power failure is predicted and the engine 11 is started and operated effectively, and the power failure period is very short, on the order of milliseconds, the fuel F is consumed.

  For this reason, in the present embodiment, the fuel amount monitoring process shown in FIG. 7 is executed by the control terminal device 20 to monitor the amount of fuel in the fuel tank 16 that has decreased due to the operation of the engine 11, that is, the remaining amount of fuel F. To do. This process starts to be executed at almost the same timing as the predicted activation process shown in FIG. 3, and waits for an activation command output in step S401. FIG. 7 is a flowchart showing the flow of the fuel amount monitoring process executed by the control terminal device 20.

  As shown in FIG. 7, in the fuel amount monitoring process, it is first determined whether or not an activation command has been sent in step S401, and waits until an activation command is sent from the control terminal device 20 (S401; No). Whether or not the start command is output is monitored by, for example, flag on setting (S115) by the predictive start process shown in FIG. This flag is the flag described above, and is provided individually for each of the plurality of emergency power generation devices 10 that can be remotely controlled by the control terminal device 20. When the activation command is sent (S401; Yes), the emergency power generation apparatus 10 that has received the activation command is identified in the next step S403, and the emergency power generation apparatus 10 to be monitored is identified. This identification is performed by an identifier associated with the previous flag.

  In step S405, a measurement start command is sent to the emergency power generator 10 identified in step S403. When the control unit 13 of the emergency power generation apparatus 10 receives this command, the flow rate data of the fuel F flowing through the pipe measured by the flow rate sensor 18b or the fuel F in the fuel tank 16 measured by the liquid level sensor 18c. Liquid level position data is acquired continuously or intermittently. In step S407, it is determined whether or not a stop command has been sent, and the process waits until a stop command is sent (S407; No).

  When a stop command is sent (S407; Yes), a measurement end command is sent to the emergency power generation apparatus 10 to be monitored in the next step S409. Upon receiving this command, the control unit 13 of the emergency power generator 10 stops the measurement by the flow sensor 18b or the liquid level sensor 18c. The control terminal device 20 performs a remaining fuel amount acquisition process in subsequent step S411. This process remains in the fuel tank 16 on the basis of the flow rate data or the liquid level position data of the fuel F sent from the emergency power generation apparatus 10 after the start command is sent and after the stop command is sent. The remaining amount of the remaining fuel F is obtained.

  For example, when the flow rate data of the fuel F is sent from the flow rate sensor 18b, the accumulated amount of the used fuel F obtained from the flow rate data is obtained from the amount of fuel stored in the fuel tank 16 before the start command is sent. By subtracting, the remaining amount of fuel F is obtained. Note that the fuel amount stored in the fuel tank 16 before the start command is sent is obtained from the emergency power generation apparatus 10 or a known fuel amount when the fuel tank 16 is full is set. When the liquid level position data of the fuel F is sent from the liquid level sensor 18c, the liquid level position data immediately after the stop command is sent or just after the sending is multiplied by the capacity per unit length of the liquid level position. Thus, the remaining amount of the fuel F is obtained.

  In the subsequent remaining fuel amount display process in step S413, the display of the remaining fuel amount obtained in step S411 is output to the display 22 and the printer 25, and further recorded in the log file by the remaining fuel amount recording process in step S415 and is recorded on the hard disk 23. Saved in. An identifier or a unique name that can identify the corresponding emergency power generation apparatus 10 is added to such display and output. When the remaining fuel amount recording process in step S415 is completed, a series of main fuel amount monitoring processes are completed.

  As described above, in the fuel amount monitoring process of the present control system, after the emergency power generation apparatus 10 starts operation in response to the start command sent in the start command send process (S113), the stop command send process (S221). Until the emergency power generation apparatus 10 receives the sent stop command and stops the operation, the fuel F used amount information used by the engine 11 is acquired by the remaining fuel amount acquiring process (S411) and acquired by this. The remaining amount information of the fuel F in the fuel tank 16 obtained based on the used amount information or the used amount information is output by the remaining fuel amount display process (S413). Thereby, the remaining amount of the fuel F in the fuel tank 16 can be grasped. Therefore, since it is possible to determine whether or not sufficient fuel F remains at the next start-up of the emergency power generation apparatus 10, when the fuel F is insufficient, fuel shortage can be avoided by refueling. can do.

Incidentally, the embodiment described above, as a creation of technical ideas can be grasped as follows. 3. The emergency power generator control system according to claim 1 or 2, wherein the engine is used after the start by the start controller until the stop by the stop controller. A fuel information acquisition unit for acquiring the used amount information of the fuel, and the remaining amount information of the fuel in the fuel tank obtained based on the used amount information acquired by the fuel information acquiring unit or the used amount information A control system for an emergency power generator, comprising: a fuel information output unit.

  In this emergency power generator control system, the fuel information acquisition unit acquires information on the amount of fuel used by the engine between the start of operation by the start control unit and the stop of operation by the stop control unit. The fuel information output unit outputs the usage amount information acquired by the fuel information acquisition unit or the remaining amount information of the fuel in the fuel tank obtained based on the usage amount information. Thereby, the remaining amount of fuel in the fuel tank can be grasped. Therefore, it is possible to determine whether or not sufficient fuel remains at the next start-up of the emergency power generation apparatus. Therefore, when the fuel is insufficient, it is possible to avoid running out of fuel in an emergency by refueling. it can.

Moreover, the power failure factor determination process (S103), the occurrence area specifying process (S105), the emergency power generation device presence determining process (S107), and the activation target specifying process (S109) by the main body unit 21 are described in the claims. It can correspond to a “power failure prediction unit”. Furthermore, the activation command sending process (S113) by the main body 21 can correspond to the “activation control unit” recited in the claims. Also, a power failure factor determination process (S207), an occurrence area identification process (S209), an emergency power generation device presence determination process (S211), a timer read process (S213), a predetermined time elapsed determination process (S215), a power failure information acquisition process ( The power failure occurrence determination process (S219) and the stop command transmission (S221) can correspond to the “stop control unit” described in the claims. Further, the driving information acquisition process (S305) by the main body 21 of the control terminal device 20 may correspond to the “driving information acquisition unit” described in the claims. Further, the engine abnormality display process (S311) by the main body 21 of the control terminal device 20 can correspond to an “abnormal information output unit” described in the claims. The memory of the main unit 21 or the hard disk 23 can correspond to the “installation point information storage unit” recited in the claims.

  As described above, in the present control system, both the emergency power generation apparatus 10 and the control terminal apparatus 20 exchange information with each other and perform control automatically without intervention of an operator or the like. This enables so-called M2M (Machine-to-Machine) by the power generation apparatus 10 and the control terminal apparatus 20.

  In the control system described above, the voltage sensor 18a has been described as an example of the operation information acquisition unit that acquires operation information of the engine 11. However, if the operation state of the engine 11 can be obtained, for example, the engine 11 may be an audio microphone that can collect 11 operation sounds (engine sound), a thermography that can detect the temperature of the engine 11 and the temperature of the exhaust port, and the like. Moreover, the data acquired by these may be output to the Internet 100 and acquired by the control terminal device 20.

  Further, in the above-described control system, the system is configured such that a plurality of emergency power generation devices 10 can be remotely controlled by one control terminal device 20. The system may be configured so that remote control can be performed by one control terminal device 20. Even in such a system configuration, the above-described prediction activation process (FIG. 3), prediction activation stop process (FIG. 4), prediction activation monitoring process (FIG. 6), and fuel amount monitoring process (FIG. 7) Similar actions and effects can be obtained.

  In addition, the system configuration in which one control terminal device 20 can remotely control one emergency power generation device 10 as described above, or the number of emergency power generation devices 10 remotely controlled by the control terminal device 20 is relatively small. In the system configuration, instead of the configuration in which the area where the disaster occurs is identified by the predictive activation process shown in FIG. 3 (S105), it is determined whether or not the emergency power generation apparatus 10 exists in the area (S107). After specifying the area where the emergency power generation device 10 exists, an algorithm may be adopted that determines whether or not a disaster occurs in that area. Thus, the person who has determined whether or not a disaster occurs in the area based on the area where the emergency power generation apparatus 10 exists does not have to determine whether there is a power outage factor in the area where the emergency power generation apparatus 10 does not exist. Since it is good (S103), it becomes possible to shorten the processing time by the control terminal device 20. FIG.

  Further, in the present control system described above, the explanation was made on the assumption that the emergency power generation device 10 and the control terminal device 20 are installed in geographically separated locations, but the emergency power generation device 10 and the control terminal device 20 are You may comprise and comprise in one housing | casing etc. In this case, the Internet 100 and the communication devices 19 and 29 that connect the two are not necessary, but the Internet 100 and the communication device 29 are used to enable data communication between the control terminal device 20 and the business operators 50 to 90. I need it. This configuration is also the same as described above in the above-described predicted startup process (FIG. 3), stop process after predicted startup (FIG. 4), monitor process after predicted startup (FIG. 6), and fuel amount monitor process (FIG. 7). The effects and effects of can be obtained.
