Description

  The present invention relates to a method for providing a maintenance service for an airport facility, a method for performing a process required for the maintenance of an airport facility, and a computer system. It relates to the maintenance and management service of airport facilities to pursue safety improvement.

  Conventionally, at airports, airport facilities such as runways, landing zones, and aprons have been maintained throughout the year so that aircraft can operate safely and smoothly.

The maintenance costs of such airport facilities are a heavy burden at each airport. For example, in the case of Tokyo International Airport (Haneda Airport), the area to be mowing is 3.2 million m ² , the number of times of mowing is 3 to 4 times a year, and if the unit price per 1 m ² is 50 yen, mowing is required. The annual cost is estimated to be 640 million yen (= 50 yen / m ² × 3.2 million m ² × 4 times).

  In fact, at Tokyo International Airport, 666.135 million yen was paid for maintenance work in FY2011, and the total number of personnel involved in maintenance work totaled about 11,1200 per year. . It should be noted that the number of people involved in mowing work stands out at 5,390 per year, and labor costs alone are estimated to be around 200 million yen.

  This mowing operation is specifically performed in an area where plants such as turf and grass grow, such as a landing zone that plays an important role in the operation of the aircraft.

  The LZ is a vast area that extends around the runway to ensure aircraft safety during landing. Article 2 of the Civil Aeronautics Act provides a landing zone for "take-off of an aircraft in a specific direction (including water take-off, the same applies hereinafter)" or landing (including water landing-the same applies hereinafter). Means a rectangular portion within an airfield. " The Enforcement Regulations of the Civil Aeronautics Act specify a reference value for the width of the landing zone according to the length and width of the runway.

  The LZs play an important role in the event that the aircraft deviates from the runway, so that vegetation such as turf and grass cushions the aircraft and minimizes damage. Further, since the landing zone is seen as a green zone from the pilot in the sky, the pilot can easily identify the runway based on the contrast between the landing zone, which is a green zone, and the asphalt runway. Furthermore, signs such as guide lights for guiding landing of the aircraft are installed in the landing zone.

  In the LZ in this role, if the plants such as grass and grass are too short, the cushioning properties when the aircraft fails to land will be impaired, and conversely the LZ grass and plants in the LZ will grow too much At the Tokyo International Airport, plants such as lawn and grass on the landing zone are difficult to see because signs such as guide lights are difficult to see, and it is difficult to get an ambulance or fire engine into the landing zone in an emergency. It is obliged to cut to 5 cm.

  At present, mowing work for mowing plants such as turf and grass in the landing zone is performed manually or by man operating a tractor. The use of such a tractor for mowing work is disclosed, for example, in US Pat. When mowing in the daytime, the worker must evacuate the tractor every time the aircraft takes off and land, and the work efficiency is low. Therefore, the work is usually performed at night. Therefore, enormous labor costs are involved in mowing the LZ.

  Furthermore, in addition to the labor costs associated with such mowing work in the LZs, work vehicles for mowing such as tractors are kept at each airport, so the purchase and maintenance costs of the working vehicles are enormous. Has become.

  At the airport, there is the problem of bird strike (bird strike), which hinders the safe and smooth operation of aircraft. At present, when a group of three people patrol the airport and see birds, a large sound generator is used. The company is implementing bird mitigation measures that emit loud sounds to repel birds, and these bird mitigation measures also require labor costs.

  In addition, at the airport, in addition to the problem that it is expensive to mow the LZ and reduce bird damage, it is important for the safe operation of aircraft that the withering of turf and grass in the LZ will cause the aircraft to fail to land. There's a problem. Here, the reason why wintering of plants such as turf and grass in the landing zone leads to aircraft landing failure is that when wintering of plants such as turf and grass in the landing zone occurs, the contrast between the runway and the landing zone decreases. This is because it becomes difficult for the pilot to identify the runway. In fact, at airports where taxiways are provided parallel to the runway, it is difficult to distinguish between the runway and the taxiway due to winter dying of vegetation such as turf and grass on the landing zone. There have been accidents such as getting off. Here, the taxiway is a passage through which the aircraft moves from an apron or the like to a predetermined position on the runway for takeoff by taxiing, or moves from the runway to the apron or the like after landing. Is a place where aircraft are parked for crew passengers getting on and off, loading and unloading cargo, refueling, simple inspection and maintenance.

(Embodiment 1)
The present invention relates to a method and a system for providing a maintenance service for an airport facility including at least one area where plants such as grass and grass grow. Airports include facilities such as landing strips, taxiways, and aprons that play an important role in the safe and smooth operation of aircraft, and the landing strips are large areas around the runway where plants such as grass and grass grow. It has spread. Note that the plant may be grass, grass, or the like, but is not limited thereto. The plant can be any plant.

  First, one mode of providing an airport facility maintenance service will be described.

(Form of providing airport facility maintenance service)
FIG. 1A shows a plurality of airports A1 to A5 served by one establishment 1000 that provides an airport facility maintenance service.

  Preferably, the plurality of airports served by one establishment 1000 are all nearby airports, but are not limited thereto. Here, the business establishment 1000 serves, for example, three airports A1 to A3 in the Kansai region and two airports A4 to A5 in the Kanto region, for example. For each of these five airports A1 to A5, A facility maintenance service S is provided. Thereby, even if each airport does not have a machine or know-how for maintaining and managing the airport facilities, it is possible to perform the maintenance of the airport facilities by the airport maintenance service provided by the business establishment 1000. is there. The airport served by one establishment 1000 is not limited to, for example, the Kansai or Kanto airports, but may be located in domestic airports such as the Tohoku, Chugoku, and Kyushu regions, or in the vicinity of the country where the establishment 1000 is located. It may be a foreign airport where it is located.

  FIG. 1B shows a state in which five airports A1 to A5 served by the business establishment 1000 are divided into two groups in order to increase the efficiency of maintenance work.

  In the example shown in FIG. 1B, airports A1 to A3 are classified into one group (unit U1), and airports A4 to A5 are classified into another group (unit U2). Airports belonging to the same group are preferably, but not limited to, close to each other. In the example shown in FIG. 1B, the runways of the airports A1 to A5 are indicated by thick lines.

  The business establishment 1000 provides an airport facility maintenance service to the airports A1 to A5 in units of these groups (that is, units). For example, the business establishment 1000 provides one or more vehicles owned by the business establishment 1000 (or the company to which the business establishment 1000 belongs) to the airport A1. For example, one or more vehicles may be carried into the airport A1 by driving and moving one or more vehicles at the office 1000. Alternatively, one or more vehicles may be carried into the airport A1 by a worker at the business establishment 1000 carrying one or more vehicles on a truck. The at least one vehicle is a vehicle (for example, a mower) used for performing maintenance of the airport facility, and maintaining the airport facility (for example, an area where plants such as lawn and grass grow such as a landing zone). A sensor that collects various data related to the growth of plants such as turf and grass that can be used for the vehicle is mounted. Here, data relating to the growth of plants such as turf and grass is at least one of environmental data indicating an environment in which plants such as turf and grass grow and growth state data indicating the growth state of plants such as turf and grass. Including one. Preferably, one or more vehicles are shared by several airports of each unit. For example, one or more vehicles may be shared by airports A1 to A3 belonging to unit U1, and one or more other vehicles may be shared by airports A4 to A5 belonging to unit U2. However, the form in which one or more vehicles for airport maintenance and management are shared by airport facilities is not limited to such a form, and for example, one or more vehicles are used by patrol at airports A1 to A3 belonging to unit U1. After that, the same one or more vehicles may be used by patrol at the airports A4 to A5 belonging to the unit U2.

  While one or more vehicles carried into the airport A1 are being used for maintenance of the airport A1, the one or more vehicles may have various data (for example, turf and data) that can be used for maintenance of the airport A1. Collect data related to the growth of plants such as grasses). The data collected by the one or more vehicles is stored in the maintenance system 100 installed in the business establishment 1000. This maintenance management system 100 generates information that can be used for maintenance of the airport A1 by processing the stored data. This information is provided to the airport A1 (for example, an administrator of the airport A1).

  One or more vehicles carried into the airport A1 are moved to the airport A2, for example, one week later, and are moved to the airport A3 one week later. In this way, one or more vehicles provided from the business establishment 1000 can be shared among the airports A1 to A3 included in the unit U1 using the unit U1 as one unit. The operation of moving one or more vehicles between airports is preferably performed by a worker at the business establishment 1000, but is not limited thereto. The shift for circulating one or more vehicles need not be performed every week, but may be performed every predetermined period. Also, at the same time that one set of one or more vehicles is carried into the airport A1, another set of one or more vehicles is carried into the airport A2, and these two sets of one or more vehicles are cyclically shared. By doing so, it is also possible to narrow the work interval.

  As described above, one or more vehicles to be carried into each airport are regularly provided from the business establishment 1000, so that each airport does not need to own one or more vehicles. Therefore, there is no need for each airport to pay for the purchase or maintenance of one or more vehicles. Further, since information that can be used for maintenance of each airport is provided from the business establishment 1000 to each airport, each airport does not need to have its own computer equipment. This allows each airport to reduce the costs required for airport maintenance.

  In the example shown in FIG. 1A, one business establishment 1000 serves five airports, but the number of airports served by one business establishment 1000 is not limited to five. One establishment 1000 can serve any number of airports. Further, in the example shown in FIG. 1B, three airports are included in one unit U1 and two airports are included in another unit U2, but the airport included in one unit is included. Is not limited to three or two. One unit can include any number of airports.

  Further, in the examples shown in FIGS. 1A and 1B, a plurality of airports served by one business office are grouped to provide the maintenance service, but the present invention is not limited to this. For example, an airport may be provided with a maintenance service for each airport without grouping a plurality of airports served by one establishment.

(Maintenance management system 100)
FIG. 2A shows an example of a configuration of the maintenance management system 100 installed in the business establishment 1000 shown in FIG. 1B.

  The maintenance management system 100 performs processing necessary for providing a maintenance service. The maintenance management system 100 includes a computer system Cs and one or more vehicles V movable on at least one area (landing zone). Here, the one or more vehicles may be a mower as described above, or may be a vehicle having no function as a mower. Further, at least one vehicle V is equipped with at least one sensor for detecting data related to the growth of plants such as grass and grass. The data related to the growth of plants such as turf and grass includes at least one of environmental data indicating an environment in which plants such as turf and grass grow and growth state data indicating the growth state of plants such as turf and grass. The environmental data includes at least one of data indicating temperature, data indicating humidity, data indicating wind direction, data indicating soil water content, and data indicating soil pH value. The growth state data includes data indicating the concentration of chlorophyll. Here, the vehicle V includes at least a moisture sensor that detects the amount of moisture in the soil, which is environmental data of a region where plants such as grass and grass grow, and a concentration of chlorophyll as a growth state of the plant such as grass and grass. A chlorophyll sensor for detecting the indicated data is preferably mounted.

  FIG. 2B shows an example of a configuration of a computer system Cs included in the maintenance management system 100 shown in FIG. 2A.

  The computer system Cs, like workers with knowledge and experience, generates reference data indicating criteria for judging work necessary for maintenance of airport facilities from data related to the growth of plants such as turf and grass. A data processing unit that creates work information indicating work required for maintenance of airport facilities by referring to reference data based on the stored database Db1 and data related to detected growth of plants such as turf and grass. Dp. In the computer system Cs, the work information created by the data processing unit Dp is stored in a storage device (not shown).

  FIG. 2C shows an example of an airport that is a target of the maintenance service. In the example shown in FIG. 2C, the airport A1 is a airport facility, a first runway 1, a first landing zone 1a provided to surround the first runway 1, a first apron 1b, a first runway 1 A first taxiway 1c, a second runway 2, a second landing zone 2a provided to surround the second runway 2, a second apron 2b, a second runway 1, and a second runway. There is a second guide path 2c connecting the second apron 2b. The reference data is based on, for example, two parameters of the soil water content and the chlorophyll concentration in an area where plants such as turf and grass grow as the first landing zone 1a and the second landing zone 2a of the airport A1. It is data for determining the amount of watering and the amount of spraying of fertilizers, fungicides, herbicides, etc. in this area based on the experience. The reference data is stored in the database Db1 in a table format, for example. However, the reference data is based on the two parameters of soil moisture and chlorophyll concentration in the area where plants such as turf and grass grow at the airport A1, and based on the knowledge and experience of the workers, watering amount and fertilizer in this area However, the present invention is not limited to data for determining the spray amount of a fungicide, a herbicide, or the like. If the reference data can be determined from various parameters, the work required for the maintenance and management of the area where plants grow, such as turf and grass at the airport, can be determined in the same way as knowledgeable and experienced workers.

Further, in the map format information, areas requiring spraying of fertilizers, fungicides, herbicides, and the like are indicated by different colors, and areas requiring a large amount of spray are areas requiring a small amount of spray. It is shown in a darker color than.

  In addition, the computer system Cs illustrated in FIG. 2B may include a database Db3 that stores data related to the growth of plants such as grass and grass, in addition to the databases Db1 and Db2. In this case, it is possible to accumulate data relating to the growth of plants such as turf and grass in the individual landing zones at the airport, and to standardize work for management and maintenance of the airport landing zones.

  FIG. 3 shows an example of processing executed by the computer system Cs shown in FIG. 2B.

  Step Pa: While the one or more vehicles V are moving on at least one area where plants such as turf and grass are growing (for example, the landing zone at the airport A1), the computer system Cs Data related to the growth of plants such as turf and grass detected by at least one sensor mounted on one or more vehicles at at least one point in the area (e.g., the environment in which plants such as turf and grass are growing) And / or growth state data indicating the growth state of plants such as grass and grass). Environmental data includes, for example, data indicating soil moisture in an area where plants such as turf and grass including the landing zone grow, data indicating temperature in this area, data indicating humidity, data indicating wind direction, soil pH. The data includes at least one piece of data indicating a value. The data indicating the growth state of plants such as turf and grass includes, for example, data indicating the chlorophyll concentration of plants such as turf and grass. However, the data indicating the growth state of the plant such as grass or grass may further include data indicating the height of the plant such as grass or grass. Data related to the growth of plants, such as turf and grass, detected by sensors mounted on one or more vehicles is transmitted wirelessly from one or more vehicles and received by computer system Cs via a wireless network. Thereby, the information may be obtained by the computer system Cs. Alternatively, when data related to the growth of plants such as grass and grass detected by a sensor mounted on one or more vehicles is stored in a medium memory in one or more vehicles, the medium memory is stored in a computer. It may be obtained by the computer system Cs by inserting it into the slot of the system Cs. The manner in which the computer system Cs acquires data related to the growth of plants such as turf and grass detected by at least one sensor mounted on one or more vehicles may be any manner.

  Step Pb: The computer system Cs generates information that can be used for maintenance of the landing zone of the airport A1 based on the data related to the growth of plants such as grass and grass acquired in Step Pa. Here, the information that can be used for the maintenance of the airport A1 may be the data itself related to the growth of plants such as turf and grass. Alternatively, the information that can be used for the maintenance of the LZ at the airport A1 may be work information indicating the work required for the maintenance of the LZ at the airport A1. For a specific example of how the computer system Cs generates work information indicating work required for maintenance of the landing zone at the airport A1 based on data related to the growth of plants such as grass and grass, This will be described later with reference to FIGS. 6A and 6B.

  Step Pc: The computer system Cs outputs the information generated in Step Pb (that is, information that can be used for maintenance of the landing zone of the airport A1). Here, the format of the information output from the computer system Cs may be any format. For example, the information output from the computer system Cs may be printed on a paper medium or recorded on a recording medium. In this case, information that can be used for maintenance of the landing zone of the airport A1 can be provided to the airport A1 (for example, an administrator of the airport A1) in the form of a paper medium or a recording medium. Alternatively, the information output from the computer system Cs is transmitted to the airport A1 (for example, the administrator of the airport A1) in a format transmitted from the computer system Cs to the terminal device of the administrator of the airport A1 via a wireless or wired network. May be provided.

  FIG. 4 is a diagram for explaining the basic configuration of the above-described method for providing the airport maintenance service.

  Step S1: Data related to the growth of plants such as grass and grass (for example, environmental data indicating the environment in which plants such as grass and grass grow and / or growth state data indicating the growth state of plants such as grass and grass) At least one vehicle equipped with at least one sensor that detects

  Step S2: turf, grass, etc. detected by at least one sensor at at least one point in at least one area while at least one vehicle is moving over at least one area (landing zone) of the airport facility.

(vehicle)
FIG. 5 is a diagram showing an example of the configuration of the vehicle V in the maintenance management system 100.

  The vehicle V includes a drive unit 20 for moving the vehicle, a drive control unit 30 for controlling the drive unit 20, a sensor unit 40 for detecting data related to the growth of plants such as grass and grass, and a sensor unit 40. And a data processing unit 10 for processing data relating to the growth of plants such as turf and grass detected by the method. Environmental data included in data related to the growth of plants such as turf and grass (data indicating the environment where plants such as turf and grass are growing) includes, for example, data indicating temperature, data indicating humidity, and wind direction. At least one of data indicating the soil moisture content, data indicating the soil pH value. The growth state data (data indicating the growth state of plants such as turf and grass) included in data related to the growth of plants such as turf and grass is, for example, data indicating the chlorophyll concentration of plants such as turf and grass. .

  Here, data indicating the growth state of plants such as turf and grass can be obtained, for example, by measuring the concentration of chlorophyll (chlorophyll) contained in plants such as turf and grass using a chlorophyll sensor. This is because chlorophyll plays an important role in the photosynthetic reaction of plants such as turf and grass, and its concentration can be used to determine the growth state.

  In FIG. 5, the sensor unit 40 includes a temperature sensor 41, a humidity sensor 42, a wind direction sensor 43, a soil moisture sensor 44, a soil pH sensor 45, and a chlorophyll sensor 46. What is necessary is just to include at least one of the sensors 41-46. In particular, when the amount of water in the area where plants grow such as turf and grass at the airport (for example, the landing zone) increases, pests such as earthworms that feed the birds occur, and the number of flying birds increases, As a result, the probability of bird strikes increases, so it is important to identify and address areas with high soil moisture in the LZ. Therefore, it is preferable that the sensor unit 40 of the vehicle V used at the airport includes the soil moisture sensor 44. It is preferable that the sensor unit 40 includes the chlorophyll sensor 46 from the viewpoint of grasping the growth state of plants such as turf and grass in the landing zone.

  Here, the data processing unit 10 stores the data detected by each sensor of the sensor unit 40 in the internal memory 11 in association with position data indicating at which point of the landing zone of the airport the data is measured. It is configured to be. In addition, the method of acquiring the position data indicating the position of the measurement point is not particularly limited, and includes a method of calculating based on the distance and direction moved from the reference position, a method of calculating using the satellite positioning system, and the like. The data related to the growth of plants such as turf and grass stored in the memory 11 is provided to the maintenance management system 100 of the business establishment 1000 by wireless communication or wired communication, or via a portable recording medium.

  The drive unit 20 includes a power source such as an engine and a motor, a steering mechanism, and one of a wheel, a caterpillar, a leg, and the like in contact with the ground plane L. It is configured to be able to switch back and forth.

  The drive control unit 30 controls the drive unit 20 so that the vehicle V moves along a determined course. For example, the drive control unit 30 controls the drive unit so that the vehicle travels along a guidance line installed in the landing zone of the airport, or uses a satellite positioning system to display map data on the landing zone of the airport. The drive unit is controlled so as to move on the LZ according to the set course. However, the configuration of the drive control unit 30 is not limited to these configurations.

  Next, a description will be given of a process in which the vehicle V creates information used for maintenance and management of the landing zone 1a in the first landing zone 1a of the airport A1.

  First, the configuration of the first runway 1 of the airport A1 and its surroundings will be briefly described.

(1st runway 1 of airport A1)
6A and 6B are a plan view and a perspective view showing an example of the configuration of the first runway 1 of the airport A1 and its surroundings.

  On both sides and both ends of the first runway 1, first landing zones 1a are provided so as to surround the first runway 1. A taxiway 1c is provided along the first runway 1 to connect the first runway 1 to the first apron 1b (see FIG. 2C).

  Next, a procedure for creating information used for maintenance and management of plants such as turf and grass in the first landing zone 1a will be described.

  As shown in FIG. 1B, the airport A1 forms a unit U1 which is a unit provided with the maintenance service by the business establishment 1000 together with nearby airports A2 to A3.

  When the maintenance service is provided to the airports A1 to A3 of the unit U1, one or more vehicles V are put into the airport A1 from the business establishment 1000. Here, two vehicles V are put into the first landing zone 1a of the airport A1, and as shown in FIG. 6B, one vehicle V is connected to one end of the first runway 1 in the first landing zone 1a ( The other vehicle V is arranged at a detection start point Sp2 close to the other end of the first runway 1 in the first landing zone 1a (right side on the back side of the paper). Shall be. Here, the case where the sensors 41 to 46 of each vehicle V detect temperature data, humidity data, wind direction data, soil moisture content data, soil pH data, and chlorophyll concentration will be described.

  The vehicle V arranged at the detection start point Sp1 moves along the route P1, and at a plurality of positions along the route P1, the sensors 41 to 46 detect temperature data, humidity data, wind direction data, and soil moisture content. Data, soil pH data, and chlorophyll concentration are detected. The detected data is stored in the internal memory 11 by the data processing unit 10 in association with the position data indicating the detected position. The vehicle V starting from the detection start point Sp2 moves along the route P2, and at a plurality of positions along the route P2, the sensors 41 to 46 detect temperature data, humidity data, wind direction data, soil moisture content data, and soil data. Detect pH data, chlorophyll concentration. The detected data is stored in the internal memory 11 in the data processing unit 10 in association with the position data indicating the detected position. Here, the position data may be data indicating the position of the airport A1 with respect to the reference position, or may be position data indicated by latitude and longitude information by a satellite positioning system. Furthermore, position data indicating the position shown on the map of the airport A1 may be based on the latitude and longitude information obtained by the satellite positioning system.

  When data related to the growth of plants such as turf and grass in the first landing zone 1a is detected by the two vehicles V in this manner, the second landing zone 2a is similarly subjected to vegetation such as grass and grass. Data related to growth is detected and stored in the memory 11 of the data processing unit 10.

  The detection processing of data related to the growth of plants such as grass and grass at such airports is performed in parallel at the three airports A1 to A3 in the unit U1. The vehicle V is returned to the establishment 1000 almost simultaneously from the airports A1 to A3.

  The data related to the growth of plants such as grass and grass stored in the memory 11 of the data processing unit 10 of the plurality of vehicles V collected at the business office 1000 is the computer system Cs of the maintenance management system 100 shown in FIG. 2A. Is passed to the data processing unit Dp (FIG. 2B). The transfer of data from the data processing unit 10 of the vehicle to the data processing unit Dp of the computer system Cs may be performed via a recording medium, or may be performed via a network such as a wired LAN or a wireless LAN. . Further, the maintenance management system 100 provided in the business establishment 1000 is configured to include a wireless communication unit, and the vehicle V is configured to include a wireless communication device, and is associated with the position data by the data processing unit 10 of the vehicle V. The data related to the growth of plants such as grass and grass may be received by the maintenance management system 100 provided at the business office 1000 by a wireless communication device and output to the computer system Cs.

  When data related to the growth of plants such as turf and grass is provided to the data processing unit Dp of the computer system Cs, the data processing unit Dp refers to the reference data in the database Db1 to grow the plants such as turf and grass. Based on the data related to the above, the work information indicating the work required for the maintenance of the landing zones at the airports A1 to A3 of the unit U1 is created. This work information is provided from the business establishment 1000 to each of the airports A1 to A3 of the unit U1.

  This work information indicates work required in a work area such as the first landing zone 1a, for example. This work information may be, for example, information obtained from data indicating the state of the first landing zone 1a. This work information is, for example, information that is reflected in a subsequent work plan, measures for airport facilities, and the like. The data indicating the state of the first LZ 1a is measured at an arbitrary measurement point on the first LZ 1a. As such work information, the airport A1 is provided with work information necessary for maintenance and management of plants such as grass and grass in the first landing zone 1a and the second landing zone 2a of the airport A1. In addition, work information necessary for maintenance of plants such as turf and grass in the respective landing zones is provided to the airport A2 and the airport A3 as in the airport A1.

  Further, the work information includes data related to the growth of plants such as turf and grass in the vehicle V, as well as data such as flying birds and dead leaves, depending on what data is detected as data representing the maintenance state of the airport facility. May be indicated. Further, the work information can also instruct the coloring work of plants such as turf and grass on the landing zone. In the coloring (coloring), the growth state of the turf or grass or the like is determined based on the data indicating the growth state of the turf or grass or the like included in the data related to the growth of the plant such as turf or grass. Based on the results, it is possible to use a method in which scallop shells are colored with crushed powder and sprayed. As the coloring agent for coloring plants such as turf and grass, it is desirable that the coloring agent be green and have an adhesive property for removing dust or dust (for example, dust) soared into the air by takeoff or landing of an aircraft. As a result, the boundary between the asphalt runway and the landing zone in the green belt is sharpened, so that dust and the like are reduced, and as a result, safety in aircraft operation is expected to be improved. Further, the coloring agent may not have such adhesiveness. In addition, the coloring agent has at least one of quasi-nonflammability in consideration of an emergency fire and the like and a property of promoting photosynthesis of plants such as turf and grass, in addition to or instead of the adhesiveness. It may be. For example, a property that promotes photosynthesis in plants can be imparted to the colorant depending on the color of the colorant. By promoting such photosynthesis, the underground temperature of a region where plants such as turf and grass grow can be increased as compared to before the coloring. Also, by utilizing the characteristic of the colorant that the underground temperature becomes warmer than before such coloring, a snow melting effect may be obtained if a certain amount of snow falls.

  In addition, an instruction of a coloring operation for winter withering, in which plants such as grass and grass wither in winter, can be given based on seasonal information.

  Seasonal information can be obtained from the clock function of the computer system Cs. The color of a plant such as grass or grass can be determined by an image sensor or the like. Therefore, it is possible to create information instructing an operation of coloring a plant, such as grass or grass, withered in winter to an approximate color (green) based on the output of the sensor.

  Thereafter, according to the schedule information at the business establishment 1000, when the business operator enters a plurality of vehicles collected from the airports A1 to A3 of the unit U1 into the airports A4 to A5 of the unit U2, the airports A1 to A5 of the unit U1 enter the vehicles. As performed in A3, at the airports A4 to A5 of the unit U2, the vehicle V detects data data related to the growth of plants such as grass and grass. It should be noted that the schedule information at the business establishment 1000 is a vehicle patrol work plan in consideration of the region, the season, and the like, and indicates the frequency of providing airport facility maintenance service to airports in which regions throughout the year. It is a plan. Thereafter, the vehicle V is collected at the business establishment 1000.

  This work information is provided from the business establishment 1000 to each of the airports A4 to A5.

  As described above, in the first embodiment, the airports A1 to A5 are provided with the vehicles V equipped with the sensors for detecting data related to the growth of plants such as grass and grass (for example, environmental data and / or growth state data). Based on the data detected by using the sensor of the vehicle V, work information indicating work required for maintenance of the landing zone at each of the airports A1 to A5 is created, and the created work information is provided to each of the airports A1 to A5. Therefore, in each of the airports A1 to A5, the work standards can be clarified and standardized. Therefore, even for workers with little knowledge and experience or unmanned work vehicles, maintenance of the landing zone of the airport facility can be performed based on the work information. Work required for management can be performed efficiently. As a result, it is possible to reduce costs required for the maintenance of the airport facilities.

  In particular, based on the detected environmental data and / or growing state data, the computer system Cs refers to the reference data indicating the criteria of the operator who has the experience and knowledge, and the computer system Cs performs the work required for the maintenance and management of the airport landing zone. Is determined, the shortage of workers with experience and knowledge can be resolved.

  In addition, airport facilities have a lot of aircraft taking off and landing and can only work at night, facilities that have few aircraft taking off and landing and can work during the day while checking the operation status, and problems such as noise from work to the neighborhood. There are facilities in various situations, such as facilities that can not work at night, so the work required for the maintenance and management of airport facilities is performed by unmanned work vehicles based on a work plan that considers the situation at each airport, resulting in efficiency. Bad work can be avoided. Furthermore, because environmental data and / or growth status data can be accumulated at airport facilities, standardization of the work required for maintenance and management of airport facilities such as the landing zone, where turf and grass grow, is an area where plants grow. Can also.

  Further, since a system for creating work information indicating work required for maintenance of airport facilities is provided by the business establishment 1000 which provides the maintenance service for airport facilities, equipment required for creation of work information is provided at the airport. No need to buy. As a result, equipment maintenance and fuel costs are reduced, and personnel can be reduced by unmanned operation.

  In the first embodiment, a vehicle V equipped with a sensor for detecting data related to the growth of plants such as grass and grass in an airport facility is provided to airports A1 to A5, and data detected using the vehicle V is provided. The case where the business establishment 1000 provides the service to the airports A1 to A5 with the work information indicating the work required for the maintenance of the LZs at the airports A1 to A5 obtained from The place 1000 may also provide the airport with a service for performing the work required for the maintenance of the airport facilities indicated by the work information.

  In this case, an unmanned vehicle or the like that works based on the work information is also provided from the business establishment 1000 to the airport, so that the airport does not need to purchase the latest general-purpose machine for maintenance work of the landing zone. Further, in the operation by the unmanned vehicle, the influence of the weather is reduced.

  Hereinafter, the airport facility maintenance service provided from the business office to the airport is based not only on the service of providing the airport with work information indicating the work required for the maintenance of the airport facility, but also on the basis of this work information. An example including a service for performing a work necessary for maintenance of an airport facility will be described as a second embodiment.

  Hereinafter, as a maintenance service of an airport facility, a method of coloring plants such as turf and grass in response to seasonal dying of plants such as turf and grass in the landing zone according to the season will be described as a fifth embodiment.

(Embodiment 5)
A method for providing a maintenance service according to the fifth embodiment of the present invention will be described with reference to FIGS. 17A to 17C.

  FIG. 17A shows a plurality of airports A1 to A5 served by a business providing a maintenance service, and FIG. 17B shows a state in which a plurality of airport facilities provided by a business providing a maintenance service are grouped. 17C shows an operation and maintenance system of the establishment.

  Also in the fifth embodiment, as in the first to fourth embodiments, the provision of the maintenance management service to the airport is performed by a plurality of airports A1 to A5 assigned to one business office 5000, as in the first to fourth embodiments. The operation is performed by grouping into two units U1 and U2 and collectively for each group.

  In the fifth embodiment, as shown in FIG. 17C, a maintenance system 500 provided in a business establishment 5000 replaces a plurality of vehicles V included in the maintenance system 100 of the first embodiment with grass, grass, and the like. And a work vehicle Vf configured to be able to color plants such as grass and grass while moving on the area where the plants grow. Here, the computer system Csf of the maintenance management system 500 is configured to acquire work data indicating the work performed by the work vehicle Vf, create and output a work report based on the acquired work data. I have.

(Work vehicle Vf)
As shown in FIG. 18, the work vehicle Vf includes a work control unit 10f instead of the work control unit 10a of the work vehicle Va of the second embodiment, and further includes a turf or the like as a work device 50 of the work vehicle Va of the second embodiment. It is provided with coloring means 50a for coloring plants such as grass. The coloring means 50a is configured to color plants such as grass and grass on the landing zone while the work vehicle Vf is moving on the landing zone. Path information for moving the work vehicle Vf along a predetermined path is recorded in the memory 11f of the work control unit 10f. The work control unit 10f controls the drive control unit 30 and the coloring unit 50a so that the coloring unit 50a performs coloring of plants such as grass and grass while the drive control unit 30 is driving the drive unit 20. Is configured.

  The drive unit 20 and the drive control unit 30 are the same as those of the work vehicle Va of the second embodiment.

  Next, the maintenance and management service provided by the maintenance and management system 500 of the fifth embodiment will be specifically described using the airport A1 as an example.

  As shown in FIGS. 19A and 19B, a work vehicle Vf of the maintenance management system 500 is put into the airport A1 from the business establishment 5000. Here, two detection work vehicles Vf are put into the first landing zone 1a of the airport A1, and one work vehicle Vf is connected to one end of the first runway 1 in the first landing zone 1a as shown in FIG. 15B. Another work vehicle Vf is located at a work start point Sp1 close to (the left side in front of the paper) and close to the other end (right side in the back of the paper) of the first runway 1 in the first landing zone 1a. Be placed.

  The work vehicle Vf disposed at each of the work start points Sp1 and Sp2 moves the landing zone 1a along the paths P1 and P2 while coloring plants such as grass and grass on the movement path of the work vehicle Vf with a coloring agent. I do. The coloration of plants such as turf and grass is not as much as greening after the plants such as turf and grass are whitened due to winter withering (for example, around November) ) It is more efficient to go. The colorant is preferably green and has a tackiness to remove dust or dust that has soared into the air upon takeoff or landing of the aircraft. By using a coloring agent having an adhesive property for coloring a plant such as turf or grass, it is possible to prevent dust or dust flying up during takeoff and landing of the aircraft from entering the engine. However, coloring of plants such as grass and grass is not limited to the method using a coloring agent.

  Specifically, when the work vehicle Vf starts moving on the first landing belt 1a, the coloring means 50a controls the work control unit 10f so that the coloring means 50a can move a portion of the landing belt where the work vehicle Vf passes, such as turf or grass. The process of coloring the plant green with a colorant is started. When the work vehicle Vf moves along a predetermined route on the first landing zone 1a and stops at the end point, the coloring means 50a causes the plants such as turf and grass to be green with a colorant under the control of the work control unit 10f. Stop the coloring process.

  In this manner, when the work of coloring plants such as grass and grass is completed by the two work vehicles Vf in the first landing zone 1a, similarly, the grass and grass and the like are also created in the second landing zone 2a which is the remaining area. The plant is colored.

  The coloring of plants such as turf and grass in the landing zone of the airport is performed in parallel at the three airports A1 to A3 in the unit U1. Similarly, from the three airports A1 to A3 in the unit U1, the work vehicle Vf is returned to the business establishment 5000 almost simultaneously.

  Thereafter, according to the schedule management, the airport facility maintenance management service is provided to the airports A4 to A5 of the other units U2 in the same manner as the airports A1 to A3 of the unit U1.

  As described above, in the fifth embodiment, the work vehicle Vf equipped with the coloring means 50a for coloring plants such as turf and grass in green is provided to the airports A1 to A5, and the work vehicle Vf is moved while moving on the landing zone of the airport facility. Since the vehicle Vf colors plants such as turf and grass in the landing zone, it is possible to avoid a decrease in contrast between the runway and the landing zone due to winter withering of vegetation such as turf and grass in the landing zone. Therefore, the function of the LZ which plays an important role in the safe operation of the aircraft can be maintained, and the safe operation of the aircraft can be ensured.

  Note that, in the fifth embodiment, the colorant has the adhesive property of removing dust or dust soared into the air due to takeoff or landing of an aircraft, but the colorant does not have such adhesive property. It may be something. In addition, the coloring agent has at least one of quasi-nonflammability in consideration of an emergency fire and the like and a property of promoting photosynthesis of plants such as turf and grass, in addition to or instead of the adhesiveness. It may be. For example, a property that promotes photosynthesis in plants can be imparted to the colorant depending on the color of the colorant. By promoting such photosynthesis, the underground temperature of a region where plants such as turf and grass grow can be increased as compared to before the coloring. Also, by utilizing the characteristic of the colorant that the underground temperature becomes warmer than before such coloring, a snow melting effect may be obtained if a certain amount of snow falls.

  In the fifth embodiment, the work vehicle Vf is provided with only a coloring device 50a for coloring a plant such as grass or grass as a work device. However, the work vehicle Vf further includes a plant such as grass or grass. May be provided with a cutting means for cutting the stalk.

  FIG. 20 is a diagram for explaining the work vehicle Vg including the coloring means and the mowing means as described above.

  The work vehicle Vg includes a work control unit (control means) 10g in place of the work control unit 10a of the work vehicle Va of the second embodiment, and further includes a turf, grass, or the like as a work device 50 of the work vehicle Va of the second embodiment. And a cutting means 50b for cutting plants such as grass and grass.

  Similar to the work vehicle Vf of the fifth embodiment, the coloring means 50a is configured to color plants such as grass and grass on the landing zone while the work vehicle Vg is moving on the landing zone. I have. The cutting means 50b is configured to cut plants such as turf and grass on the landing belt while the work vehicle Vg is moving on the landing belt.

  Route information for moving the work vehicle Vg along a predetermined route is recorded in the memory 11g of the work control unit 10g. The work control unit 10g drives the drive control unit 30 so that the coloring of the plants such as grass and grass by the coloring unit 50a and the mowing by the cutting unit 50b are performed while the drive control unit 30 is driving the drive unit 20. It is configured to control the coloring means 50a and the cutting means 50b.

  The drive unit 20 and the drive control unit 30 are the same as those of the work vehicle Va of the second embodiment.

  With the work vehicle Vg having such a configuration, it is possible to color plants such as grass and grass while cutting grass in the landing zone, and to effectively color plants such as grass and grass shortened by grass cutting. It can be performed.

  In the work vehicle Vg shown in FIG. 20, the work control unit 10g controls the coloring unit 50a and the cutting unit 50b so that the coloring unit 50a performs coloring of plants such as grass and grass and the cutting unit 50b performs mowing. Although configured as described above, the configuration of the work control unit 10g is not limited to such a configuration.

  For example, the work control unit 10g determines that after the cutting means 50b has cut the plants such as grass and grass before the plants such as grass and grass fall into winter, the coloring means 50a controls the coloring of the plants such as grass and grass by 1 The mowing means 50b and the coloring means 50a may be controlled so as to be performed once or several times. Alternatively, the work control unit 10g may include a coloring unit 50a for coloring a plant such as grass or grass after the cutting unit 50b has cut the grass or grass before the plant such as grass or grass becomes winter withered, The cutting means 50b and the coloring means 50a may be controlled so as to adjust the density of the coloring agent when coloring a plant such as grass or grass.

Further, in the fifth embodiment, the case where the maintenance management system performs the coloring operation of plants such as turf and grass in the landing zone has been described, but the maintenance management system performs the coloring operation on the landing zone other than the landing zone in the airport. This may be performed in an area where plants such as grass and grass grow, for example, in a park in an airport, or in an area where plants such as grass and grass around a taxiway and an apron.
(Modifications of Embodiments 1 to 5)
Further, the vehicle of each of the above embodiments includes a collision avoidance sensor for a facility such as a sign provided in the landing zone, a lighting facility assuming nighttime work, a laser device for bird damage countermeasures, a large sound generation device, and the like. May be mounted. Furthermore, the vehicle is further equipped with a sensor that detects birds, and in response to the detection of the bird, the bird is irradiated with laser light emitted from a laser device for bird harm prevention, A loud sound may be generated by a loud sound generating device to intimidate a bird. For example, the laser device for bird damage control may be a thermography / laser light facility. Furthermore, during the summer season when grass and other growing materials are remarkable, the number of times of unmanned mowing, such as mowing, using vehicles equipped with the above-mentioned mowing means is increased, thereby suppressing the nesting of birds flying to airport facilities. As a result, bird strike can be reduced. In addition, collection | recovery of the cut grass after mowing by unmanned can be efficiently performed by using an unmanned roll baler or the like. Furthermore, thatch (grass debris) generated after unattended mowing can be reduced, for example, by using a decomposing agent mounted on a work vehicle to spray the decomposing agent to reduce the amount of residual material after mowing. can do.

  In addition, the patrol plan of the maintenance and management service of the airport facilities provided by the establishments of the above-described embodiments is a year-round plan in consideration of the region, the season, and the like. The operating efficiency of a vehicle or the like equipped in the vehicle can be improved.

  Not only grass care, but also the status of dead leaf accumulation and the occurrence of pests are subject to maintenance at the airport. Therefore, by using a sensor capable of detecting these objects to be maintained, for example, an image sensor, as a sensor mounted on the vehicle, it becomes possible to maintain and manage things other than grass at the airport. In particular, grass damage caused by pests can be effectively suppressed by anticipating and coping with the outbreak, and in the future, realizing sensors that can detect such signs of outbreak will enable It is also possible to eliminate almost no grass damage caused by the grass.

  In addition, at airport facilities in heavy snowfall areas, it is necessary to remove snow accumulated on the runway of aircraft such as runways and taxiways in winter, and snow removal on the runway is subject to maintenance of airport facilities. Become.

(Rotary snowplow AVh2)
FIG. 23B is a diagram for explaining the configuration of the rotary snowplow AVh2 provided in the maintenance system 900a. FIG. 25A is a diagram schematically illustrating an appearance of the rotary snowplow AVh2 illustrated in FIG. 23B.

  The rotary snowplow AVh2 has a vehicle body 902a and a snow removal device 902b attached to a front surface of the vehicle body 902a.

  Here, the vehicle main body 902a includes a drive unit 220, a drive control unit 330, and a work control unit 920, similarly to the vehicle main body 901a of the snow plow AVh1. The vehicle body 902a is configured to be able to supply the loaded grass powder CGr to the snow removing device 902b. Specifically, the vehicle main body 902a includes a grass powder storage unit 902 that stores the grass powder CGr, a carry-out unit 924 that carries out the grass powder CGr from the grass powder storage unit 902, and a grass powder CGr that is carried out by air. And a transport blower 925a that transports the grass powder by flow. The grass blower is transported by the transport blower 925a to the snow removing device 902b via the transport duct 925b. Here, the grass powder is obtained by finely pulverizing and coloring grass obtained by mowing in summer, and is stored in a warehouse or the like in an airport for recycling. The grass powder is carried out of the warehouse as needed during snow removal work in winter and loaded on the rotary snow plow AVh2.

  The snow removing device 902b includes a cylindrical snow scraper roller 926 that scrapes snow by rotation, a pair of left and right roller support plates 926a that rotatably supports the snow scraper roller 926, and a pair of upper and lower support plates that support each roller support plate 926a. And a support arm 926b. Here, a motor for rotating the snow scraper roller 926 is built in the roller support plate 926a. One end of the support plate support arm 926b is fixed to the roller support plate 926a, and the other end of the support plate support arm 926b is rotatably attached to the vehicle body 902a. The rotation of the support plate support arm 926b is performed by an actuator (not shown) attached to the vehicle body 902a.

  The snow removing device 902b further includes a mixer 927 that mixes the grass powder conveyed from the vehicle body 902a with snow scraped by the snow scraper roller 926, and a snow blowing unit 928 that blows out the snow SGm mixed with the grass powder. Have. The snow blowing part 928 has a blowing pipe 928a and a blowing blower 928b. The mixer 927 is fixed to the roller support plate 926a, and the snow blowing part 928 is attached to the upper part of the mixer 927.

  In this rotary snowplow AVh2, the drive unit 220 and the drive control unit 330 are the same as those in the side snow plow AVh1, and the work control unit 920 is the work control unit 910 of the side snow plow AVh1. In the same manner as described above, a transmission / reception unit (not shown) for transmitting / receiving information to / from the computer system ACsh via a memory 921 and a line such as a wireless LAN is provided. However, the operation control unit 920 controls the drive control unit 330 based on the operation contents instructed by the computer system ACsh, and also controls the motors of the unloading means 924, the transport blower 925a, the mixer 927, the blower blower 928b, and the snow scraper roller 926. , And is configured to control the actuator of the mounting plate support arm 926b.

  Next, a maintenance service (snow removal operation) provided by the business establishment 9000a to the airport shown in FIG. 22 will be described.

  When the computer system ACsh of the maintenance and management system 900a of the business establishment 9000a acquires the snow information at the airport shown in FIG. 22, it instructs the side-side snowplow AVh1 and the rotary-type snowplow AVh2 to perform snow removal. This instruction is received by the work control unit 910 of the side snow plow AVh1 and the work control unit 920 of the rotary snow plow AVh2 via a line such as a wireless LAN. Here, it is assumed that the side snow plow AVh1 and the rotary snow plow AVh2 are previously carried in from the business office to the airport based on a weather forecast or the like and stored in a hangar or the like in the airport.

  First, a plurality of side snow plows AVh1 perform snow removal work on the runway.

  FIG. 24B is a diagram for explaining an example of the snow removal operation by the side-side snowplow AVh1 shown in FIG. 24A.

  The work control unit 910 of the plurality of side snow plows AVh1 detects the position of the center line of the runway 61 based on the map information of the airport, and according to the work content (execution of snow removal work) instructed from the computer system ACsh. Of the snowplow relative to the center line of the runway 61 is determined. When the running position of each side-side snowplow AVh1 is determined, the plurality of side-side snowplows AVh1 start with the side-side snowplow AVh1 running on the center line of the runway 61 as shown in FIG. 24B. A formation is formed such that a plurality of snow plows AVh1 are arranged on both sides, respectively, and the vehicle runs from one end of the runway 61 to the other end. The snow Sn accumulated on the runway 61 is brought to both sides of the runway 61 by the running of the snow plow AVh1 on the runway 61. The operation of bringing snow to the side of the runway as described above is usually completed by running the snow plow AVh1 once or several times on the runway 61. FIG. 24C shows a state in which the snow removal work by the side-side snowplow AVh1 shown in FIG. 24A has been completed. As described above, when the snow removal operation by the side snow plow AVh1 is completed, the snow removal operation by the rotary snow plow AVh2 is subsequently performed.

  FIG. 25B is a diagram for explaining an example of the snow removal operation by the rotary snow plow AVh2 shown in FIG. 25A.

  Here, the plurality of rotary snow plows AVh2 perform the snow removal work for removing snow collected on the side of the runway, and at the same time, the boundaries between the runway 61 and the landing zones 6a on both sides of the runway 61 become clear. In this way, the operation of coloring the landing zones on both sides of the runway 61 is also performed. The coloring operation is performed by scattering grass powder stored in a warehouse at the airport on the landing zone 6a.

  This will be specifically described below.

  In advance, grass powder CGr carried out from a warehouse at an airport is loaded in grass powder storage units 902 of a plurality (for example, two) of rotary snow plows AVh2. When the work control unit 920 of the rotary snowplow AVh2 receives an instruction of the work content (snow removal work) from the computer system ACsh, the work control unit 920 detects the position of the center line of the runway 61 based on the map information of the airport. Then, the running position of each snowplow relative to the center line of the runway 61 is determined based on the work content (snow removal work) instructed from the computer system ACsh. In the case of the rotary snowplow Vh2, the snow removal work is performed to remove the snow brought to the side of the runway 61 by the side snow plow AVh1, so that the scene in front of the vehicle is photographed by an image sensor or the like while the vehicle is running. The optimal running position for snow removal work may be determined by analyzing the captured image.

  When the two rotary snow plows AVh2 are positioned at the snow removal start position (for example, both side portions at one end of the runway 61) and the snow removal work by the rotary snow plow AVh2 is started, the rotary snow plow AVh2 Snow collected on both sides of the runway 61 is taken in by a snow scraper roller 926 of the snow removing device 902b, and the taken-in snow is blown out toward a landing zone by a snow blowing unit 928 via a mixer 927. While such snow is taken in and blown out, in the rotary snow plow AVh2, the grass powder stored in the grass powder storage unit 902 is transported to the transport blower 925a by the unloading means 924, and the grass is further removed. The powder is transported to the mixer 927 by the transport blower 925a via the transport duct 925b. Since the snow taken in by the snow scraper roller 926 is supplied to the mixer 927, grass powder is mixed into the snow in the mixer 927, and the snow SGm containing the grass powder is directed from the snow blowing part 928 to the landing zone side. Is blown out. For this reason, the portion of the landing zone 6a adjacent to the portion of the runway 61 where the snow removal work by the rotary snowplow AVh2 has been completed is, as shown by the dot display in FIG. 42B, a colored grass powder (for example, green). Will be colored.

  The operation of blowing off the snow collected on the side of the runway as described above is usually completed by running the rotary snow plow AVh2 at least once on the runway 61. FIG. 25C shows a state in which snow removal work by the rotary snow plow AVh2 shown in FIG. 25A has been completed.

  Further, the snow removal work by the side snow plow AVh1 and the rotary snow plow AVh2 is similarly performed not only on the runway 61 but also on the taxiway 6c.

  However, at the airport, there is a case where the hands are not sufficiently turned to the snow on the taxiway 6c due to the snow removal work on the runway 61. In such a case, the snow removal on the taxiway 6c may be only the snow removal by the rotary snow plow AVh2. This is because, on the taxiway 6c, the aircraft only moves by low-speed taxiing, so that even if there is some snowfall, if the boundary between the taxiway and the surrounding green belt (the taxiway green belt) can be clearly defined. This is because the movement of the aircraft on the taxiway is possible. Specifically, when the rotary snowplow AVh2 performs snow removal on the side edges of the taxiway, snow including colored grass powder is scattered to the area around the taxiway (the greenway of the taxiway). Road green belt is colored. Thereby, the pilot can recognize both side edges of the taxiway.

  When the snow removal work on the runway 61 and the taxiway 6c is completed as described above, the aircraft is ready for takeoff and landing at the airport.

  When snow keeps falling, the snow removal work by the side snow plow AVh1 and the rotary snow plow AVh2 is performed intermittently. However, when the snow stops falling, the snow plow AVh1 and the rotary snow plow are used. The snow removing operation by the snow removing vehicle AVh2 is completed, and these working vehicles are returned to the hangar or the like. Further, if the weather forecast predicts that snow will not fall for a while thereafter, these work vehicles are temporarily returned to the office 9000a.

  As described above, in the sixth embodiment, the side-moving snowplow AVh1 and the rotary-type snowplow AVh2 are provided to the airport, and these snowplows are used to remove the snow on the runway of the aircraft such as the runway 61 and the taxiway 6c of the airport facility. The coloring of the landing zone and the green area of the taxiway is performed at the same time, and the reduction of the contrast between the running path and the area around the running path (green zone) due to snowfall can be improved simultaneously with the snow removal work on the running path. As a result, even in a heavy snowfall area in winter, the function of the traveling path that plays an important role in the safe operation of the aircraft and the function of the surrounding green belt can be maintained, and the safe operation of the aircraft can be ensured.

  In the sixth embodiment, grass powder obtained by finely crushing and coloring the cut grass is used for coloring. However, when coloring snow, the snow taken into the rotary snowplow AVh2 is Ash and charcoal obtained by burning the cut grass may be mixed. When charcoal is mixed in, the surface of the landing zone and taxiway green zone becomes black and the absorption of sunlight is promoted, so the temperature rises, and the snow melting action and grass photosynthesis in the landing zone and taxiway green zone increase. Promoted. In the rotary snowplow AVh2, it is needless to say that a snow melting agent may be mixed into the taken snow and the snow may be blown off together with the snow melting agent.

  Further, for coloring snow taken into the rotary snowplow AVh2, scallop shells may be crushed or scallop shells may be crushed and colored. Because the scallop shell has a glossy surface, even if it is not particularly colored, crushed pieces of scallop shells are mixed with snow and scattered in the landing zone or taxiway green area, so that the surface of the landing zone or taxiway green zone can be improved. Since it shines upon receiving sunlight, the boundary between the runway 61 and the landing zone 6a and the boundary between the taxiway 6c and the green taxiway are clear.

  In addition, maintenance services for airport facilities according to the weather include those that provide snow removal work in winter and those that remove puddles due to guerrilla heavy rain in summer.

  Specifically, the area (green belt) where plants grow around the runway, such as the runway and taxiway, is not flat but uneven, so there are landing zones and taxiways around the runway due to guerrilla downpours in summer. Puddles may be formed in the surrounding taxiway green area. Leaving the puddles formed in the area where plants grow around the road in this way, many pests that feed on birds such as earthworms occur, which increases the number of birds flying to the airport. This causes an adverse effect that the probability of occurrence of a bird strike increases. Especially in subtropical regions such as Southeast Asia, storms with storms accompanied by heavy rain frequently occur (squalls). Therefore, airport facilities in such regions have previously produced such heavy rains (for example, precipitation up to 100 mm per hour). Although it is designed in consideration, when a guerrilla torrential rain (for example, 300 mm per hour) occurs, a puddle may be formed in a green belt (an area where plants grow) around the traveling path. For this reason, depending on the airport, it is necessary to remove puddles formed in the green belt due to guerrilla downpours and the like, and the puddle formed in the green belt is also a target for maintenance of the airport facilities.

  Hereinafter, as a maintenance and management service for airport facilities, a method of providing a service for performing a puddle removing operation for removing a puddle formed in a green belt around a traveling road will be described as a seventh embodiment.
