BRIEF DESCRIPTION OF THE DRAWINGS It is a whole block diagram which concerns on the management system which is one Example.

  One or more components arbitrarily selected from the present specification may be added to the above-described components of the present invention. The contents described in the present specification may be appropriately applied not only to the management system of the present invention, but also to the road unit as the premise thereof. Whether or not which embodiment is the best depends on the target, required performance, and the like.

Road Unit
(1) Road units are not completed by civil engineering work on site as in the past. It is a block-like module or assembly that can be completed in the factory by connecting at the factory where it is produced in advance.

  The road unit includes, for example, a surface layer portion, an elastic portion, a roadbed portion, and a roadbed portion in order from the surface side to the ground side. The surface layer portion is made of, for example, a paved road such as asphalt or concrete. The elastic portion is made of, for example, a shock absorbing material that absorbs deformation of the surface layer portion and non-landing of the roadbed portion and suppresses the generation of local load on the surface layer portion. The roadbed portion is a portion that receives the distributed load from the upper layer portion (surface layer portion, elastic portion) and maintains the entire structure. The roadbed portion is a portion that transmits the distributed load from the upper layer portion (surface layer portion, elastic portion, roadbed portion) to the ground.

  The road unit may not be limited to the multi-layered structure composed of the above-described parts, but may include infrastructure equipment such as water and water and information communication. In any case, by using the road unit, not only new roads can be built, but also repair and replacement (replacement) of deteriorated and damaged roads can be performed efficiently.

(2) In order to operate the management system of the present invention, it is preferable that a number of existing road units have individual identification information that can identify them. The individual identification information is, for example, an identification number assigned to each road unit, and is stored in a storage device, a memory, or the like provided for each.

  In addition, it is preferable that the road unit has a sensor (including a gauge, a measuring device, etc.) for acquiring damage information that causes deterioration or damage. For example, it is various sensors which can detect load information which acts on each road unit by passage of a vehicle, etc., environment information etc. which each road unit after construction receives.

  As a sensor which acquires load information, there are a load sensor, a strain gauge, etc., for example. As a sensor which acquires environmental information, there are a temperature sensor, a humidity sensor, a salinity sensor etc., for example. Each piece of information may be continuous information obtained from each sensor, or may be discrete information or the like including an excess for a predetermined value (threshold value) and the number of times thereof.

  The road unit preferably includes transmission means for transmitting the damage information to the management system (reception means) in order to reflect the respective information in the management system. The transmission of each information may be made at any time or continuously, or may be performed regularly or intermittently. Moreover, it is preferable that transmission of each information is made using an infrastructure (a communication network, a power supply, etc.) embedded in the road unit. Communication between the road unit and the management system may be wireless communication or wired communication as long as the transmission unit of the road unit and the reception unit of the management system correspond to each other.

Management system
The management system is configured by a computer system installed at a road unit manufacturer (company), a seller or a road manager. The management system includes at least a damage amount calculation unit, a life prediction unit, and an update calculation unit, in addition to the reception unit. Hereafter, each means with which the management system of this invention is provided is explained in full detail. The “means” in the present specification is realized by a computer program, and can be appropriately replaced with “step” (step). And "management system" can also be put in another way "management method".

(1) Damage amount calculation means The damage amount calculation means calculates the damage amount indicating the degree of deterioration or damage of the road unit (also referred to simply as "damage") based on the damage information received from the road unit side. . The amount of damage is calculated based on, for example, the following index values.

  Based on load information obtained from a load sensor or the like provided in the road unit, a load index value that causes damage to the road unit is calculated. The load index value is, for example, an integrated value (integrated value) obtained from the weight and the number (number of times) of vehicles passing through the road unit. In addition, the load index value may be an integrated value of excess weight exceeding a predetermined value. Besides, the load index value may be calculated using the amplitude of load fluctuation and the number of times.

  In addition to physical factors such as load, environmental factors (including chemical factors) are also factors that cause damage to road units. For example, based on environmental information obtained from a temperature sensor, a humidity sensor or the like provided in the road unit, an environmental index value that causes damage to the road unit is calculated. The environmental index value can be obtained, for example, as an integrated value of the excess and time when the road unit is exposed to a temperature or humidity exceeding the set range. In addition, the construction site of the road unit is various, and there are not only inland areas but also coastal areas and factories. In such places, not only temperature and humidity, but also salinity, acidity, etc. are environmental (chemical) factors that damage road units. For example, based on chemical information obtained from a salinity sensor or the like provided in the road unit, a chemical index value that causes damage to the road unit is calculated. The chemical index value can be obtained, for example, as an integrated value of excess and time when the road unit is exposed to a salt atmosphere or the like exceeding the set range.

  The damage amount calculation means can calculate the damage amount from the respective index values thus obtained. The amount of damage may be calculated separately (for example, physical damage, environmental damage, chemical damage, etc.) according to each index value, or the damage amount calculated by combining each index value may be calculated. May be In the latter case, it can be calculated, for example, by appropriately weighting each index value.

(2) Life Prediction Means The life prediction means calculates the remaining life of each road unit based on the history of damage amount (for example, accumulated amount, change amount, etc.) described above. For example, for each road unit, the accumulated total damage amount, the time change rate of the damage amount, and the like are obtained, and are compared with a set value (for example, an allowable cumulative damage amount). The difference between the two (the degree of margin to the set value) is the remaining life of each road unit.

(3) Update calculation means The update calculation means calculates the update information of the road unit based on the remaining life mentioned above. For example, when the remaining life of an existing road unit becomes shorter than a predetermined period (for example, June, 1 year, etc.), information (update information) to be replaced (updated) with a new road unit provide. The update information is, for example, the update time of each road unit (the end date of the end of life, the remaining life, etc.), the number of updates required for construction (the number of new road units required), and the like. In addition to the update information, it is preferable that specifications (structures, materials, individual features, and the like) of each road unit, a construction site, and the like are provided.

(4) Production Support Means The production support means provides production information of a new road unit to be exchanged based on the above-described update information. The production information is, for example, selection of a production facility (factory) or establishment of a new plant required for production of a new road unit required for replacement, the number and ability of personnel, and the like. Further, the construction information may include construction information on equipment, personnel, etc. required for construction of a new road unit.

(5) Task Extraction Means The task extraction means extracts the task information on the construction site of the road unit or the road unit based on the update information or the history of the update information. For example, for road units constructed in a specific area or road units with specific specifications, if the update time is much earlier than the originally scheduled time (design value), or the road unit update (replacement) takes a short time If there is a history of repeated, etc., it is conceivable that the construction method, the specification of the road unit, the roadbed, the roadbed, etc. with respect to the ground of the construction site are inadequate. When such task information (improvement information) is extracted and provided by the task extraction means, maintenance management of the road and improvement of the road unit can be performed more efficiently.

  An overview of a management system S according to an embodiment of the present invention is shown in FIG. The management system S manufactures and maintains the roads 1 constructed at various places (sites) by a number of road units r1, r2, r3... (Simply referred to as "road units r") and each road unit r It is comprised by the operating company 2.

  An identification number (individual identification information) is assigned to each road unit r, and is stored in a built-in memory (not shown). Based on the identification number, basic information such as specifications, manufacturing date, manufacturing location (factory), construction location, construction date, use start date and the like, damage information to be described later, remaining life, and the like are specified for each road unit r.

  In each road unit r, a load sensor 11, a temperature sensor 12, a humidity sensor 13, a salt component sensor 14 and the like are embedded in order to acquire the damage information. A communication device 10 (transmission means) capable of transmitting a signal obtained from each sensor is also provided inside. Each sensor and the communication device 10 are driven by an infrastructure power supply in the road unit r, a solar battery provided for each road unit r, and the like. The communication device 10 can be connected to the Internet line n by an infrastructure communication network in the road unit r, a wireless transmitter provided for each road unit r, and the like.

  Damage information obtained from each sensor of the road unit r is transmitted to the computer c of the management unit of the operating company 2 through the Internet line n. The computer c acquires damage information through the communication device 20 (reception means). The computer c calculates the damage amount for each road unit r based on the damage information (step 21 / damage amount calculation means). The amount of damage is calculated, for example, based on information (signals) taken from each sensor of the road unit r, based on a predetermined equation, a load index value, an environment index value, a chemical index value, and the like. The damage amount for each road unit r is calculated by applying each index value to another predetermined equation.

  The computer c calculates the remaining life of each road unit r based on the damage amount (step 22 / life prediction means). The remaining life may indicate a usable remaining time or may indicate a replacement time (last date and time).

  The computer c stores the remaining life of each road unit r in the storage device (step 23). The storage device also stores the basic information described above in addition to the damage amount (details of each index value) for each road unit r based on the above-described identification number.

  The computer c monitors the remaining life of each road unit r updated as needed, and when the remaining life becomes shorter than a predetermined period, the replacement time of the corresponding road unit r and the quantity of the corresponding road unit r ( Update information is calculated and provided (step 24).

  The updated information of the road unit r is provided to the manufacturing unit (factory) in the operating company 2. The manufacturing unit manufactures a new road unit r and transports it to the construction site so that the replacement can be completed within the remaining life of each road unit r.

  The updated information of the road unit r is also provided to the planning department in the operating company 2, and when there are a large number of road units r to be replaced, a new plant for manufacturing a new road unit r for replacement, construction of a factory for that plant Plan staffing, preparation of construction work, etc. At this time, it is preferable that the computer c automatically provides production information such as the location and size of a factory to be newly established, and the number of personnel required (production support means).

  Furthermore, the computer c analyzes the update information of the road unit r or its history, and if the road unit replacement time (update time) is much earlier than expected, or if the exchange is repeated in a short period of time Preferably, the task information is automatically provided to the design department or the like of the operating company 2 (task extraction means). As a result, the construction site of the road unit and the road unit itself can be efficiently improved.

  By the way, the operating company does not have to be in the same country as the road site. Furthermore, there is no need for each department (management department, manufacturing department, planning department, etc.) of the operating company to be in the same region or in the same country. Furthermore, the operating company may be composed of a plurality of independent companies (management company, manufacturing company, construction maintenance company, etc.). The manufacturing department (company) and the construction maintenance department (company) are preferably located near the site where the road is located.
