[Technical field]

[0001] The present invention relates to a temporary construction equipment and materials management system for managing various temporary construction equipment and materials used at predetermined locations in a building under construction. [Background technology]

[0002] A site management system has been disclosed that includes multiple wireless tags attached to site workers and site equipment, and multiple receiving antennas that are installed indoors and receive the radio waves emitted from the wireless tags, analyzes the radio waves received from the wireless tags by the receiving antennas, and detects the position of the wireless tags based on a reference direction in terms of the arrival angle of the radio waves (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-138785 A Summary of the Invention [Problem to be solved by the invention]

[0004] The site management system disclosed in Patent Document 1 receives radio waves emitted from wireless tags attached to site workers and site equipment by multiple receiving antennas installed indoors, and by analyzing the angle of arrival (AoA) of the received radio waves by the multiple receiving antennas, the indoor position of the wireless tag can be easily determined, and the positions of site workers and site equipment can be quickly and accurately determined.

[0005] However, this site management system cannot confirm in real time whether the site equipment and materials used at a specific location (construction site) of the building under construction are operating (in operation) or stopped (not operating), and cannot grasp the operating status of the site equipment and materials. Furthermore, even if unused site equipment and materials are left at the construction site, it is not possible to grasp the operating status of each site equipment and materials, so it is not possible to distinguish between site equipment and materials that are being used and site equipment and materials that are not being used. As a result, unused site equipment and materials are left at the construction site for a long period of time, and it is not possible to efficiently use a variety of site equipment and materials at the construction site. Furthermore, if unused site equipment and materials are left at the construction site for a long period of time, the site equipment and materials also incur costs, and it is not possible to reduce the costs of site equipment and materials used at the construction site.

[0006] The object of the present invention is to provide a temporary equipment and materials management system that can confirm in real time whether various types of temporary equipment and materials used at specified locations in a structure under construction are operating (in operation) or stopped (not operating), and can accurately grasp the operating status of these temporary equipment and materials. Another object of the present invention is to provide a temporary equipment and materials management system that can distinguish between temporary equipment and materials that are being used in a structure under construction and temporary equipment and materials that are not being used, can prevent unnecessary temporary equipment and materials from being left unused for long periods of time, and can realize efficient use of various types of temporary equipment and materials in a structure under construction. [Means for solving the problem]

[0007] The present invention for solving the above problem is based on the premise that a plurality of 1st to nth receivers are installed at predetermined locations of a structure under construction, a plurality of 1st to nth transmitters for equipment and materials are installed on a plurality of various 1st to nth temporary equipment and materials used at predetermined locations of the structure under construction, and transmit position information radio waves indicating equipment and material position information signals of the 1st to nth temporary equipment and materials while individually identifying the 1st to nth temporary equipment and materials, and a plurality of 1st to nth workers working in the structure under construction. ofThe temporary equipment management system is formed from a plurality of 1st to nth transmitters for workers that emit position information radio waves indicating equipment use position information signals, and 1st to nth receivers receive the position information radio waves emitted from the 1st to nth transmitters for equipment and the 1st to nth transmitters for workers. The system has an equipment position identifying means for identifying the positions of the 1st to nth temporary equipment in a structure based on the position information radio waves received by the 1st to nth receivers, and an equipment use position identifying means for identifying the equipment use positions of the 1st to nth workers in the structure.

[0008] As a feature of the present invention based on the above premise, In the temporary equipment management system, a building is divided into predetermined areas 1 to n, and 1 to n receivers are installed in each of the 1 to n areas. The temporary equipment management system an area specifying means for specifying in which of the first to nth areas the position of the temporary equipment transmitting the position information radio wave and the position of the equipment use by the worker transmitting the position information radio wave are located, while referring to the position of the temporary equipment transmitting the position information radio wave specified by the equipment position specifying means and the position of the equipment use by the worker transmitting the position information radio wave specified by the equipment use position specifying means; a duration measuring means for measuring a duration during which the position of the temporary equipment transmitting the position information radio wave and the position of the equipment use by the worker transmitting the position information radio wave are located in the same area, when the position of the temporary equipment transmitting the position information radio wave and the position of the equipment use by the worker transmitting the position information radio wave are located in the same area, and an operation determining means for determining that the temporary equipment transmitting the position information radio wave is in operation, when the duration measured by the duration measuring means is equal to or longer than a preset time. The purpose of the present invention is to have the following features.

[0009] As one example of the present invention, a temporary equipment management system includes a distance measuring means for measuring the distance between the temporary equipment position emitting position information radio waves located in the same area and the equipment use position of the worker emitting position information radio waves, while referring to the equipment position of the temporary equipment emitting position information radio waves identified by the equipment position identifying means and the equipment use position of the worker emitting position information radio waves identified by the equipment use position identifying means, and the operation determination means determines that the temporary equipment emitting position information radio waves is in operation when the distance between the temporary equipment position emitting position information radio waves and the equipment use position of the worker emitting position information radio waves is within a predetermined set distance.

[0010] As another example of the present invention, the temporary equipment management system includes a lost / stolen determination means for determining that temporary equipment located in an area different from the placement area or temporary equipment whose location is unknown is lost or stolen temporary equipment when the location of temporary equipment in a structure specified by the equipment location specifying means is different from the placement area of ​​the temporary equipment registered in advance, or when the location of the temporary equipment becomes unknown when the equipment location specified by the equipment location specifying means is a location of the temporary equipment registered in advance.

[0011] As another example of the present invention, a temporary equipment management system includes a temporary equipment position output means for outputting the first to nth areas of a building and outputting the positions of temporary equipment in each of the first to nth areas of the building, and a temporary equipment operation status output means for outputting the operation status of the temporary equipment in the first to nth areas as determined by the operation determination means.

[0012] As another example of the present invention, a temporary equipment management system includes a temporary equipment data management means for outputting various temporary equipment data for temporary equipment that is in operation or not in operation in the first to nth areas determined by the operation determination means, and a worker data management means for outputting various worker data for workers using the temporary equipment that is in operation.

[0013] As another example of the present invention, a temporary equipment management system includes an operation rate calculation means for calculating the operation rate during a predetermined period of temporary equipment operated in first to nth areas determined by an operation determination means, and an operation rate output means for outputting the operation rate calculated by the operation rate calculation. Effect of the Invention

[0014] According to the temporary equipment management system of the present invention, when the relationship between the location of the temporary equipment emitting location information radio waves and the location of the worker emitting location information radio waves using the equipment meets specific predefined conditions, the temporary equipment is determined to be in operation, and when the relationship between the location of the temporary equipment emitting location information radio waves and the location of the worker emitting location information radio waves using the equipment is not in a predetermined state, the temporary equipment is determined to be out of operation. Therefore, it is possible to confirm in real time whether various types of temporary equipment used at specific locations in a structure under construction are in operation (in operation) or stopped (out of operation), and the operating status of those temporary equipment can be accurately grasped. The temporary equipment management system can check whether temporary equipment is in operation or not, and can therefore distinguish between temporary equipment that is being used in a structure under construction and temporary equipment that is not being used, preventing unused temporary equipment from being left for long periods of time, and realizing efficient use of a variety of temporary equipment in a structure under construction (introduction of temporary equipment adapted to the construction plan and progress, and temporary placement of temporary equipment in appropriate locations).The temporary equipment management system can identify the locations of the first through nth temporary equipment in a structure under construction, making it possible to know where the temporary equipment is located in the structure under construction, and even if multiple construction companies are working simultaneously in the structure under construction, the locations of the temporary equipment in the structure of the structure under construction can be confirmed in real time. The temporary equipment management system can confirm at any time where temporary equipment is located in a structure under construction without confusing it with temporary equipment from other companies, which can reduce the costs associated with managing temporary equipment (the human labor and time required to find where temporary equipment is located in a structure under construction).The temporary equipment management system can confirm temporary equipment that has not been used for a specified period of time, which can return temporary equipment that has not been used for a specified period of time to the leasing company or rental company, thereby reducing the costs associated with temporary equipment (leasing fees, rental fees, etc.).

[0015] A temporary equipment management system divides a building into 1st to nth areas, installs 1st to nth receivers in each of the 1st to nth areas, and, while referring to the equipment position of the temporary equipment transmitting location information radio waves and the equipment use position of the worker transmitting location information radio waves, identifies in which of the 1st to nth areas the equipment position of the temporary equipment transmitting location information radio waves and the equipment use position of the worker transmitting location information radio waves are located, and determines that the temporary equipment transmitting location information radio waves is in operation when the equipment position of the temporary equipment transmitting location information radio waves and the equipment use position of the worker transmitting location information radio waves are located in the same area, The system is based on the condition that the equipment location and the location of the worker using the equipment and emitting location information radio waves are located in the same area, and when the temporary equipment location and the worker using the equipment location are located in the same area, it is determined that the temporary equipment and emitting location information radio waves are in operation, and when the temporary equipment and the worker using the equipment location are not located in the same area, it is determined that the temporary equipment and emitting location information radio waves are not in operation. Therefore, it is possible to confirm in real time whether various types of temporary equipment and materials used in specified locations of a structure under construction are in operation (in operation) or stopped (not in operation), and the operating status of those temporary equipment and materials can be accurately grasped. The temporary equipment management system can realize the efficient use of multiple types of temporary equipment in structures under construction, reducing the costs associated with temporary equipment (leasing fees, rent, etc.) as well as the costs associated with managing temporary equipment (the human labor and time required to find where a company's temporary equipment is located, even if other companies' temporary equipment is mixed in with the structure under construction).

[0016] A temporary equipment management system that determines that a specific temporary equipment is in operation when a specific temporary equipment among the first to nth temporary equipment is associated with a specific worker among the first to nth workers who uses the specific temporary equipment and the equipment position of the specific temporary equipment that is transmitting a location information radio wave and the equipment use position of the specific worker that is transmitting a location information radio wave using the specific temporary equipment are located in the same area, and determines that the temporary equipment is in operation when a specific temporary equipment is in operation and the equipment position of the specific temporary equipment that is transmitting a location information radio wave and the equipment use position of the specific worker that is transmitting a location information radio wave are located in the same area, and determines that the temporary equipment is in operation and the equipment position of the specific worker that is transmitting a location information radio wave are in operation. The temporary equipment transmitting location information radio waves is determined to be in operation when the location of use and the location of a specific worker are located in the same area, and the temporary equipment transmitting location information radio waves is determined to be out of operation when the location of the specific temporary equipment and the location of the specific worker are not located in the same area, so it is possible to check in real time whether a specific temporary equipment among multiple types used at a specific location in a building under construction is in operation (in operation) or has stopped (out of operation), and it is possible to accurately grasp the operating status of the temporary equipment (whether the temporary equipment is being used by a cooperating company or worker who was scheduled to use the equipment in the prior construction plan). The temporary equipment management system can realize efficient use of multiple types of temporary equipment in a building under construction, reduce costs associated with temporary equipment (lease fees, rent fees, etc.), and reduce costs associated with managing the temporary equipment (manpower and time required to find where the temporary equipment is located in a building under construction and to consider a temporary storage site).

[0017] A temporary equipment management system measures the duration when the location of temporary equipment emitting location information radio waves and the location of a worker using the equipment emitting location information radio waves are located in the same area, and if the measured duration is equal to or longer than a predetermined set time, determines that the temporary equipment emitting location information radio waves is in operation.If the measured duration is less than a predetermined set time, it determines that the temporary equipment emitting location information radio waves is stopped (not in operation).By doing so, it is possible to eliminate short-term non-operating actions such as checking the location or status of the temporary equipment from being in operation, and it is possible to accurately grasp the operating status (operating or not in operation) of the temporary equipment.

[0018] A temporary equipment management system measures the distance between the position of temporary equipment emitting location information radio waves located in the same area and the position of a worker using the equipment emitting location information radio waves, and determines that the temporary equipment emitting location information radio waves is in operation if the distance between the position of the temporary equipment emitting location information radio waves and the position of the worker using the equipment emitting location information radio waves is within a predetermined set distance.If the measured distance exceeds a predetermined set distance, it determines that the temporary equipment emitting location information radio waves is stopped (not in operation), thereby making it possible to eliminate non-operating actions that are different from actual operation, such as checking the position or status of the temporary equipment from a long distance, from the operating state, and to accurately grasp the operating status (operating or not operating) of the temporary equipment.

[0019] If the location of temporary equipment in an identified structure is different from the placement area registered in advance, or if the location of the temporary equipment becomes unknown when the location of the temporary equipment registered in advance is identified, the temporary equipment management system determines that temporary equipment located in an area different from the placement area or whose location becomes unknown is lost or stolen temporary equipment.If the location of temporary equipment in a identified structure is different from the placement area registered in advance, the temporary equipment management system determines that temporary equipment located in an area different from the placement area is lost or stolen temporary equipment, and for example outputs (displays) a lost message, allowing the user to know that the temporary equipment is lost and the temporary equipment can be placed (moved) to the correct placement area. If the location of temporary equipment becomes unknown, the temporary equipment management system determines that the missing temporary equipment is lost or stolen, and for example outputs (displays) a lost or stolen message, thereby enabling the user to know that the temporary equipment has been lost or stolen and to take measures to locate it.

[0020] A temporary equipment management system that outputs the 1st to nth areas of a building, outputs the positions of temporary equipment and materials in each of the 1st to nth areas for the temporary equipment and materials present in the 1st to nth areas, and outputs the operating status of temporary equipment and materials in operation in the 1st to nth areas, makes it possible to know where the 1st to nth temporary equipment and materials are located in the 1st to nth areas by outputting the positions of the temporary equipment and materials in each of the 1st to nth areas for the temporary equipment and materials present in the 1st to nth areas, and makes it possible to accurately grasp the positions of each temporary equipment and materials at a construction site of a large-scale building (wide site or multi-story), and to know whether each temporary equipment and materials is in operation or not. The temporary equipment management system allows workers to reach specific temporary equipment and materials without getting lost, and to immediately operate the temporary equipment and materials.

[0021] The temporary equipment management system, which inputs and outputs various data on temporary equipment and materials in operation or non-operation in the first to nth areas to computer resources and outputs various worker data on workers using the temporary equipment and materials in operation, can know various temporary equipment and materials data such as the type, model, name, provider, and usage method of the temporary equipment and materials in operation or non-operation, and can know various worker data such as the worker's name, affiliation, and work content of the worker using the temporary equipment and materials in operation, and can provide work guidance based on these data, thereby making it possible to confirm that the temporary equipment and materials are being used by cooperating companies and workers as scheduled, and to ensure the safety of various tasks and workers. Since various worker data can be input through a network system, it is unnecessary for foremen of multiple cooperating companies to gather at the same time and place in advance to adjust the use of the temporary equipment and materials.

[0022] The temporary equipment management system calculates the operation rates for a specified period of temporary equipment and materials operated in the first to nth areas and outputs the calculated operation rates, and can identify temporary equipment and materials with low operation rates by taking the calculated operation rates into consideration, and by increasing the operation rates of temporary equipment and materials with low operation rates, it is possible to realize efficient use of multiple types of temporary equipment and materials in a structure under construction.The temporary equipment management system can reduce costs associated with temporary equipment and materials (leasing fees, rental fees, etc.) by returning temporary equipment and materials with low operation rates that have not been used for a specified period to leasing companies, rental companies, etc. [Brief description of the drawings]

[0024] The details of the temporary equipment management system according to the present invention will be described below with reference to the attached drawings such as Fig. 1, which is a configuration diagram showing an example of a temporary equipment management system 10. Fig. 1 illustrates two aerial work vehicles (first and second temporary equipment 14a, 14b) and two table lifts (third and fourth temporary equipment 14c, 14d) arranged at predetermined locations in the structure under construction (construction site), and four workers (first to fourth workers 15a to 15d) working at predetermined locations in the structure under construction (construction site), but in reality, a number of different types of temporary equipment (first to nth temporary equipment) greater than those shown are arranged at predetermined locations in the structure under construction (construction site), and a number of workers (first to nth workers) greater than those shown perform various tasks at predetermined locations in the structure under construction (construction site).

[0025] 1 shows one gateway 16 (communication protocol conversion device), five first to fifth receivers 11a to 11e, four first to fourth transmitters 12a to 12d (beacons) for materials and equipment, and two first and second transmitters 13a, 13b (beacons) for workers, but in reality, a greater number of gateways 16 than shown are installed at predetermined locations in the building under construction, a greater number of first to nth receivers than shown are installed at predetermined locations in the building under construction, a greater number of first to nth transmitters for materials and equipment than shown are installed in the first to nth temporary materials and equipment, and a greater number of first to nth transmitters for workers than shown are held by a greater number of first to nth workers. For example, when the total floor area is 50,000 m 2 For a building under construction, 7-10 gateways, 40-50 receivers, and 300-350 transmitters will be used.

[0026] The temporary equipment and materials management system 10 manages a variety of first to nth temporary equipment and materials used at a predetermined location (construction site) of a structure under construction. The variety of first to nth temporary equipment and materials includes all temporary equipment and materials currently used at the structure under construction (construction site) such as aerial work vehicles, table lifts, mobile lifting scaffolding, concrete piping racks, balcony ladders, hatch-type scaffolding boards, safety nets, curing sheets, soundproofing panels, temporary fencing, etc., as well as various types of temporary equipment and materials to be developed in the future.

[0027] The temporary equipment management system 10 is composed of a plurality of first to fifth receivers 11a to 11e (first to nth receivers), a plurality of first to fourth equipment transmitters 12a to 12d (beacons) (first to nth equipment transmitters), and a plurality of first to fourth worker transmitters 13a to 13d (beacons) (first to nth worker transmitters). The first to fifth receivers 11a to 11e are installed in predetermined locations (indoors and outdoors of the building) of a building under construction (construction site) to form a mesh network.

[0028] As an example of a mesh network, the EXBeacon platform is used, which is a large-scale network that enables mutual communication (two-way communication) between beacons by using Bluetooth mesh. By using the EXBeacon platform, the first to fifth receivers 11a to 11e receive radio waves transmitted from the first to fourth equipment transmitters 12a to 12d (first to nth equipment transmitters) and the first to fourth worker transmitters 13a to 13d (first to nth worker transmitters), and the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) and the first to fourth workers 15a to 15d (first to nth workers) in the building (construction site) can be measured (detected).

[0029] The first to fifth receivers 11a to 11e are installed at predetermined locations in a building under construction (construction site). The receivers 11a to 11e are capable of receiving radio waves transmitted from within a radius of approximately 30 m from the receivers 11a to 11e. Therefore, the receivers 11a to 11e are installed at predetermined locations in the building (construction site) at intervals of approximately 30 m. The first to fifth receivers 11a to 11e are connected to a gateway 16.

[0030] The gateway 16 is connected to a receiver information server 17 (database server) via the Internet. The receiver information server 17 is connected to a Web application server 18 (WebAP server) via the Internet. The receiver information server 17 and the Web application server 18 are constructed in the cloud, but may be physical servers installed locally at the work site. Terminal devices such as personal computers 19 and tablets managed by the manager (management company) and users (user companies) of the temporary equipment management system 10 are connected to the Web application server 18 via the Internet.

[0031] The receiver information server 17 and the Web application server 18 are virtual computers (or physical computers) equipped with a central processing unit (CPU or MPU), memory (main memory and cache memory), and a large-capacity storage area, and form a network with other servers in a data center installed somewhere in the world via the Internet. The receiver information server 17 and the Web application server 18 have a DNS server function, a database server function, a Web server function, a mail server function, and a document server function, and are divided by software according to each server function. These servers 17 and 18 can access any other server with no access restrictions using the Internet, passing through a variety of DNS servers and the like connected to the Internet.

[0032] The large capacity storage area of ​​the Web application server 18 (and the receiver information server 17) stores (memorizes) temporary equipment identification information that individually identifies the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment), and stores (memorizes) worker identification information that individually identifies the first to second workers 15a to 15d. The large capacity storage area of ​​the Web application server 18 and the receiver information server 17 stores (memorizes) receiver identification information that individually identifies the first to fifth receivers 11a to 11e (first to nth receivers), registers and stores (memorizes) equipment transmitter identification information that individually identifies the first to fourth equipment transmitters 12a to 12e (first to nth equipment transmitters), and registers and stores (memorizes) worker transmitter identification information that individually identifies the first to fourth worker transmitters 13a, 13b (first to nth worker transmitters).

[0033] The large capacity storage area of ​​the Web application server 18 stores (memorizes) preset equipment transmitter identification information, preset worker transmitter identification information, preset set time information, and preset set distance information. The transmitter information, set time information, and set distance information can be changed as appropriate using an input device (touch panel operation, keyboard, mouse, etc.). The Web application server 18 (temporary equipment management system 10) divides a building under construction into predetermined 1st to nth floors (1st to nth areas). The large capacity storage area of ​​the Web application server 18 stores (memorizes) 1st to nth floor maps (1st to nth area maps) of the divided 1st to nth floors (1st to nth areas).

[0034] The temporary equipment identification information includes the model numbers and individual identification numbers of the temporary equipment that individually identify (specify) the first to fourth temporary equipment 14a to 14d (1st to nth temporary equipment), as well as the names of the temporary equipment 14a to 14d, the names of the providers (leasing company names, renters, etc.), the operation methods (methods of use) of the temporary equipment 14a to 14d, the fees (lease fees, rent fees, etc.) of the temporary equipment 14a to 14d, images of the temporary equipment 14a to 14d, etc. The receiver information server 17 or the Web application server 18 may independently generate unique temporary equipment identifiers that identify (specify) the first to fourth temporary equipment 14a to 14d (1st to nth temporary equipment), and the generated temporary equipment identifiers may be used as the temporary equipment identification information.

[0035] The worker identification information includes a worker number for individually identifying (identifying) the first to fourth workers 15a to 15d (first to nth workers), as well as the name of the company to which the workers belong, the names of the workers 15a and 15b, employee numbers, the addresses of the companies to which the workers belong, the telephone numbers of the companies to which the workers belong, email addresses, ages, and genders, etc. The receiver information server 17 or the Web application server 18 may independently generate unique worker identifiers for identifying (identifying) the first to fourth workers 15a to 15d (first to nth workers), and the generated worker identifiers may be used as the worker identification information.

[0036] The receiver identification information can use the individual identification numbers of the first to fifth receivers 11a to 11e (first to nth receivers), or the receiver information server 17 or the Web application server 18 can independently generate unique receiver identifiers that identify (specify) the first to fifth receivers 11a to 11e, and use the generated receiver identifiers as the receiver identification information. The transmitter identification information for equipment and the transmitter identification information for workers can use the individual identification numbers of the first to fourth transmitters 12a to 12d for equipment (first to nth transmitters for equipment) and the first to fourth transmitters 13a to 13d for workers (first to nth transmitters for workers). Alternatively, the receiver information server or the Web application server 18 can independently generate a unique transmitter identifier that identifies (specifies) the first to fourth transmitters 12a to 12d for equipment and the first to fourth transmitters 13a to 13d for workers, and the generated transmitter identifier can be used as the transmitter identification information for equipment and the transmitter identification information for workers.

[0037] The transmitter identification information for equipment and materials (1st to nth transmitter identification information for equipment and materials) is stored in a large-capacity memory area of ​​the Web application server 18 (and the receiver information server 17) in a state associated with the temporary equipment and materials identification information (1st to nth temporary equipment and materials identification information). For example, the first equipment transmitter 12a (equipment transmitter identification information) and the first temporary equipment 14a (temporary equipment identification information) are associated with each other, the second equipment transmitter 12b (equipment transmitter identification information) and the second temporary equipment 14b (temporary equipment identification information) are associated with each other, the third equipment transmitter 12c (equipment transmitter identification information) and the third temporary equipment 14c (temporary equipment identification information) are associated with each other, and the fourth equipment transmitter 12d (equipment transmitter identification information) and the fourth temporary equipment 14d (temporary equipment identification information) are stored in an associated state in the large-capacity storage area of ​​the Web application server 18 (and the receiver information server 17).

[0038] The first equipment transmitter 12a is attached to a predetermined location of the first temporary equipment 14a (aerial work vehicle) by a predetermined fixing means, the second equipment transmitter 12b is attached to a predetermined location of the second temporary equipment 14b (aerial work vehicle) by a predetermined fixing means, the third equipment transmitter 12c is attached to a predetermined location of the third temporary equipment 14c (table lift) by a predetermined fixing means, and the fourth equipment transmitter 12d is attached to a predetermined location of the fourth temporary equipment 14d (table lift) by a predetermined fixing means.

[0039] As described below, when workers 15a to 15d reserve temporary equipment 14a to 14d, worker transmitter identification information (worker transmitters 1 to n) is stored in the large-capacity storage area of ​​the Web application server 18 (and receiver information server 17) in a state associated with worker identification information (worker 1 to n). For example, the first worker transmitter 13a (worker transmitter identifying information) and the first worker 15a (worker identifying information) are associated with each other, the second worker transmitter 13b (worker transmitter identifying information) and the second worker 15b (worker identifying information) are associated with each other, the third worker transmitter 13c (worker transmitter identifying information) and the third worker 15c (worker identifying information) are associated with each other, and the fourth worker transmitter 13d (worker transmitter identifying information) and the fourth worker 15d (worker identifying information) are stored in a large-capacity storage area of ​​the Web application server 18 (and the receiver information server 17).

[0040] The first worker transmitter 13a is attached by a predetermined fixing means to a first key 20a necessary for starting and stopping the first temporary equipment 14a (aerial work vehicle) that the first worker 15a plans to use, and is held by the first worker 15a together with the first key 20a. The second worker transmitter 13b is attached by a predetermined fixing means to a second key 20b necessary for starting and stopping the second temporary equipment 14b (aerial work vehicle) that the second worker 15b plans to use, and is held by the second worker 15b together with the first key 20a. tree The first and second keys 20a and 20b are each assigned a key number.

[0041] The third worker transmitter 13c is attached to a first name tag 21a representing the third temporary equipment 14c (table lift) to be used by the third worker 15c by a predetermined fastening means, and is held by the third worker 15c together with the first name tag 21a. The fourth worker transmitter 13d is attached to a second name tag 21b representing the fourth temporary equipment 14d (table lift) to be used by the fourth worker 15d by a predetermined fastening means, and is held by the fourth worker 15d together with the second name tag 21b. The first and second name tags 21, 21 are assigned tag numbers.

[0042] The first to fourth equipment transmitters 12a to 12d (first to nth equipment transmitters) transmit location information radio waves (including individual identification numbers or transmitter identifiers that individually identify the first to fourth equipment transmitters 12a to 12d, and model numbers, individual identification numbers, or temporary equipment identifiers that individually identify the first to fourth temporary equipment 14a to 14d) indicating equipment location information signals of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment). The first to fourth worker transmitters 13a to 13d (first to nth worker transmitters) transmit position information radio waves (including individual identification numbers or transmitter identifiers for individually identifying the first to fourth worker transmitters 13a to 13d, and worker numbers or worker identifiers for individually identifying the first to fourth workers 15a to 15d) indicating equipment use position information signals of the first to fourth workers 15a to 15d (first to nth workers).

[0043] The first to fifth receivers 11a to 11e (1st to nth receivers) receive location information radio waves (including equipment transmitter identification information (individual identification number or transmitter identifier) ​​that individually identifies the first to fourth equipment transmitters 12a to 12d) transmitted from the first to fourth equipment transmitters 12a to 12d (1st to nth equipment transmitters), and transmit the location information radio waves received from the first to fourth equipment transmitters 12a to 12d and the receiver identification information (individual identification number or receiver identifier) ​​that individually identifies the first to fifth receivers 11a to 11e (1st to nth receivers) to the receiver information server 17 via the gateway 16.

[0044] The first to fifth receivers 11a to 11e (1st to nth receivers) receive location information radio waves (including worker transmitter identification information (individual identification number or transmitter identifier) ​​that individually identifies the first to fourth worker transmitters 13a to 13d) transmitted from the first to fourth worker transmitters 13a to 13d (1st to nth worker transmitters), and transmit the location information radio waves received from the first to fourth worker transmitters 13a to 13d and the receiver identification information (individual identification number or receiver identifier) ​​that individually identifies the first to fifth receivers 11a to 11e (1st to nth receivers) to the receiver information server 17 via the gateway 16.

[0045] The first to fourth temporary equipment and materials 14a to 14d (first to nth temporary equipment and materials) are transported from a leasing company or a rental company to a structure under construction (construction site) and placed on a predetermined floor 23 (predetermined area (location)) of the structure under construction. The placement floors (placement areas) of the first to fourth temporary equipment and materials 14a to 14d (first to nth temporary equipment and materials) for the structure under construction are determined in advance.

[0046] The placement floor information (placement area information) of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) is stored (stored) in the mass storage area of ​​the Web application server 18 (and the receiver information server 17) in a state associated with the temporary equipment specification information (first to nth temporary equipment specification information). For example, if it is decided that the first temporary equipment 14a will be placed on the 5F floor (5F area), the 5F floor (5F area) is stored (stored) in the mass storage area of ​​the Web application server 18 (and the receiver information server 17) in a state associated with the first temporary equipment 14a (temporary equipment specification information), and if it is decided that the nth temporary equipment will be placed on the 10F floor (10F area), the 10F floor (10F area) is stored (stored) in the mass storage area of ​​the Web application server 18 (and the receiver information server 17) in a state associated with the nth temporary equipment (temporary equipment specification information).

[0047] A terminal device (computer resource) such as a personal computer 19 or a tablet connected to the Web application server 18 for communication can reserve the use of the first to fourth temporary equipment and materials 14a to 14d (first to nth temporary equipment and materials). An example of the reservation procedure will be described below, taking as an example a case where the first worker 15a plans to use the first temporary equipment and materials 14a. Note that illustrations of each reservation screen output (displayed) on the display 22 of the personal computer 19 are omitted. When the personal computer 19 is connected to the Web application server 18 via the Internet, a menu screen (initial screen) of the temporary equipment and materials management system 10 is output (displayed) on the display 22 of the personal computer 19.

[0048] The menu screen displays (outputs) a button for outputting reserved temporary equipment and materials, a button for reserving temporary equipment and materials, a button for outputting operation status, a button for outputting temporary equipment and materials / worker data, a button for outputting operation rate, and a cancel button. Clicking the cancel button logs you out of the Web application server 18 (temporary equipment and materials management system 10). To reserve the use of temporary equipment and materials, click the temporary equipment and materials reservation button from the menu screen displayed (output) on the display 22 of the computer 19. Clicking the temporary equipment and materials reservation button causes a temporary equipment and materials reservation screen to be displayed (output) on the display 22 of the computer 19.

[0049] Images of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) are output (displayed) on the temporary equipment reservation screen. The first worker 15a (or manager) double-clicks on the image of the first temporary equipment 14a that he / she wishes to use from among the images of the first to fourth temporary equipment 14a to 14d. When the image of the first temporary equipment 14a is double-clicked, a reservation status screen for the first temporary equipment 14a is output (displayed) on the display 22 of the personal computer 19. On the reservation status screen, the reserved dates and times of the first temporary equipment 14a divided by time, the available reservation dates and times divided by time, an area for inputting the worker number, a decision button, a clear button, and a cancel button are output (displayed).

[0050] The first worker 15a (or manager) selects (highlights) the planned date and time of use of the first temporary equipment 14a, inputs the worker identification information (worker number or worker identifier) ​​in the worker number input area, and then clicks the Confirm button. When the Confirm button is clicked, the selected (highlighted) planned date and time of use of the first temporary equipment 14a is incorporated into the reserved date and time, and a reservation confirmation screen is output (displayed) on the display 22 of the PC 19. An image of the first temporary equipment 14a, the planned date and time of use, the worker identification information, and the key number of the first key 20a of the first temporary equipment 14a are output on the reservation confirmation screen.

[0051] When the first worker 15a reserves the first temporary equipment 14a, the first worker transmitter 13a (worker transmitter identification information (individual identification number or transmitter identifier)) and the first worker 15a (worker identification information (worker number or worker identifier)) are stored (memorized) in an associated state in the large-capacity memory area of ​​the Web application server 18 (and the receiver information server 17), and the planned date and time of use, the worker identification information, and the key number of the first key 20a of the first temporary equipment 14a are stored (memorized) in an associated state with the worker transmitter identification information and the worker identification information.

[0052] Fig. 2 is a diagram of a floor image showing an example of a floor 23 (area) of a building (construction site) under construction, and Fig. 3 is a diagram of a floor image in which first to fourth temporary materials and equipment 14a to 14d arranged on a specific floor 23 of the building (construction site) under construction are output (displayed). As shown in Fig. 2, a floor image of each floor of the building (construction site) under construction is output (displayed) on a display 22 of a personal computer 19 connected to a Web application server 18. In the floor image of Fig. 2, first and second receivers 11a and 11b installed on the floor 23 are output (displayed).

[0053] The first to fourth temporary equipment and materials 14a to 14d are arranged on the floor 23 (area). After the first to fourth temporary equipment and materials 14a to 14d are arranged on the floor 23 of the building (construction site) under construction, the first to fourth equipment and materials transmitters 12a to 12d installed on the first to fourth temporary equipment and materials 14a to 14d transmit location information radio waves (including equipment and material transmitter specific information (individual identification number or transmitter identifier) ​​and temporary equipment and material specific information (model number, individual identification number, or temporary equipment and material identifier)).

[0054] The first and second receivers 11a, 11b receive the location information radio waves transmitted from the first to fourth equipment transmitters 12a to 12d, and transmit the received location information radio waves to the gateway 16. The gateway 16 is connected to the Internet, and transmits the location information radio waves (including equipment transmitter specific information (individual identification number or transmitter identifier) ​​and temporary equipment specific information (model number, individual identification number, or temporary equipment identifier)) of the first to fourth equipment transmitters 12a to 12d to a receiver information server 17 (cloud).

[0055] The receiver information server 17 stores (stores) in a large-capacity storage area the location information data and reception date and time of the location information radio wave of the first to fourth equipment transmitters 12a to 12d received from the gateway 16 in a state associated with the receiver identification information (individual identification number or receiver identifier), equipment transmitter identification information (individual identification number or transmitter identifier), and temporary equipment identification information (model number, individual identification number, or temporary equipment identifier). The receiver information server 17 transmits the location information data, reception date and time, receiver identification information (individual identification number or receiver identifier), equipment transmitter identification information (individual identification number or transmitter identifier), and temporary equipment identification information (model number, individual identification number, or temporary equipment identifier) ​​of the location information radio wave of the first to fourth equipment transmitters 12a to 12d to the Web application server 18.

[0056] The Web application server 18 (temporary equipment management system 10) reproduces each floor (each area) of the building (construction site) under construction in a digital space (digital twin), and based on the location information data of the location information radio waves of the first to fourth equipment transmitters 12a to 12d (first to nth equipment transmitters) received from the receiver information server 17, identifies which floor (area) of the first to nth floors (first to nth areas) the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) currently emitting location information radio waves is located on (area identification means).

[0057] Furthermore, the Web application server 18 (temporary equipment management system 10) measures where the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) transmitting position information radio waves are located on the floor (area) identified by the area identification means, based on the position information data of the first to fourth equipment transmitters 12a to 12d (first to nth temporary equipment) and identifies the equipment positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) on the floor (area) of the building (construction site) under construction (equipment position identification means).

[0058] The Web application server 18 (temporary equipment management system 10) outputs (displays) a floor image shown in Fig. 3 on the display 22 of the personal computer 19. In the floor image of Fig. 3, the floors (1st to nth areas) of the building (construction site) under construction are output (displayed), and the positions of the first to fourth temporary equipment 14a to 14d (1st to nth temporary equipment) present on the floor (1st to nth areas) are output (displayed) (equipment position output means).

[0059] The temporary equipment management system 10 outputs (displays) floors (1st to nth areas) of a building (construction site) under construction, and outputs (displays) the positions of the first to fourth temporary equipment 14a to 14d (1st to nth temporary equipment) present (placed) on each floor (1st to nth area). This makes it possible to know where the first to fourth temporary equipment 14a to 14d (1st to nth temporary equipment) are present on the floor (1st to nth area), and therefore makes it possible to accurately grasp the positions of the first to fourth temporary equipment 14a to 14d (1st to nth temporary equipment) that move as work progresses at a construction site of a large-scale building (large site or multi-story). The temporary equipment management system 10 enables the first to nth workers to reach specific first to nth temporary equipment without getting lost, even if they are entering the work site for the first time, and can immediately start operating those temporary equipment.

[0060] Fig. 4 is a diagram for explaining a situation in which the first worker 15a uses the reserved first temporary equipment 14a, and Fig. 5 is a diagram for explaining a state in which it is determined that the first temporary equipment 14a is in operation. Fig. 6 is a flowchart for explaining the determination of whether the first temporary equipment 14a is in operation or not, and Fig. 7 is a flowchart continued from Fig. 6. Taking the case in which the first worker 15a uses the first temporary equipment 14a as an example, an example of a procedure for using the reserved first temporary equipment 14a arranged on the floor 23 will be described below.

[0061] The first worker 15a who has reserved the first temporary equipment 14a checks the reservation status of the first temporary equipment 14a by looking at the reservation status screen output (displayed) on the display 22 of the personal computer 19 on the previous reservation day. The first worker 15a clicks a button for outputting reserved temporary equipment on the menu screen output (displayed) on the display 22 of the personal computer 19. When the button for outputting reserved temporary equipment is clicked, images of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) that have been reserved are output (displayed), although not shown.

[0062] The first worker 15a double-clicks on the image of the reserved first temporary equipment 14a. When the image of the first temporary equipment 14a is double-clicked, a floor image of the floor 23 (area) on which the reserved first temporary equipment 14a is located is output (displayed) on the display 22 of the personal computer 19. The floor image displays the floor (area) name, floor (area) hierarchy, the equipment position of the first temporary equipment 14a on the floor (area), the name of the first worker 15a who reserved the first temporary equipment 14a, the reservation time, and the available time.

[0063] The first worker 15a, who has confirmed the reservation status and the location of the first temporary equipment 14a, receives the first key 20a for the first temporary equipment 14a from the work manager, and while holding the first key 20a, heads to the floor 23 (area) where the first temporary equipment 14a is located and starts using the first temporary equipment 14a (see FIG. 4). A location information radio wave (including worker transmitter specific information (individual identification number or transmitter identifier)) is transmitted from the first worker transmitter 13a attached to the first key 20a.

[0064] When the first worker 15a arrives at the floor 23 (area) where the first temporary equipment 14a is placed, and the first temporary equipment 14a and the first worker 15a are located on the same floor 23 (same area), the location information radio wave transmitted from the first worker transmitter 13a is received by the first and second receivers 11a and 11b installed on the floor 23 (area). The first and second receivers 11a and 11b transmit the location information radio wave received from the first worker transmitter 13a (first worker) to the gateway 16.

[0065] The gateway 16 transmits the location information radio wave (including the worker transmitter specific information (individual identification number or transmitter identifier)) to the receiver information server 17 (cloud) via the Internet. The location information radio wave is transmitted from the first to fourth equipment transmitters 12a to 12d of the first to fourth temporary equipment 14a to 14d arranged on the floor 23 (area), and the first and second receivers 11a and 11b receive the location information radio wave, which is then transmitted to the receiver information server 17 via the gateway 16.

[0066] The receiver information server 17 stores (stores) in a large-capacity storage area the location information data and reception date and time of the location information radio wave of the first worker transmitter 13a received from the gateway 16 in a state associated with the receiver identification information (individual identification number or receiver identifier), the worker transmitter identification information (individual identification number or transmitter identifier), and the worker identification information (worker number or worker identifier). The receiver information server 17 transmits the location information data of the location information radio wave of the first worker transmitter 13a, the reception date and time, the receiver identification information (individual identification number or receiver identifier), the worker transmitter identification information (individual identification number or transmitter identifier), and the worker identification information (worker number or worker identifier) ​​to the Web application server 18.

[0067] The Web application server 18 receives the location information data, reception date and time, receiver identification information (individual identification number or receiver identifier), equipment transmitter identification information (individual identification number or transmitter identifier), and temporary equipment identification information (model number or individual identification number or temporary equipment identifier) ​​of the location information radio waves of the first to fourth equipment transmitters 12a to 12b, while also receiving the location information data, reception date and time, receiver identification information (individual identification number or receiver identifier), worker transmitter identification information (individual identification number or transmitter identifier) ​​and worker identification information (worker number or worker identifier) ​​of the first worker transmitter 13a (S-1).

[0068] The Web application server 18 (temporary equipment management system 10) reproduces each floor (each area) of the building under construction (construction site) in a digital space (digital twin), and based on the location information data of the location information radio waves of the first worker transmitter 13a received from the receiver information server 17, determines which floor (area) of the 1st to nth floors (1st to nth areas) the first worker transmitter 13a (first worker 15a) currently emitting location information radio waves is located on, and identifies the floor (area) of the building under construction (construction site) on which the first worker transmitter 13a (first worker 15a) is located (area identification means).

[0069] Furthermore, the Web application server 18 (temporary equipment management system 10) measures where the first worker transmitter 13a (first worker 15a) transmitting the location information radio wave is located on the floor (area) identified by the area identification means, based on the location information data of the location information radio wave of the first worker transmitter 13a, and identifies the equipment use position of the first worker transmitter 13a (first worker 15a) on the floor (area) of the structure (construction site) under construction (equipment use position (worker position) identification means) (S-2).

[0070] As described above, the area specifying means specifies on which floor (area) of the first to nth floors (first to nth areas) the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) transmitting the location information radio wave is located. (Means for identifying equipment location) , Equipment location identification means As a result, the positions of the first to fourth temporary equipment and materials 14a to 14d (first to nth temporary equipment and materials) on the floor (area) of the building (construction site) under construction are identified.

[0071] The Web application server 18 (temporary equipment management system 10) identifies the equipment use location of the first worker 15a (first worker transmitter 13a) using an equipment use location identification means, and identifies the equipment location of the first temporary equipment 14a (first equipment transmitter 12a) using an equipment location identification means, and then determines whether the equipment use location of the first worker 15a (first worker transmitter 13a) and the equipment location of the first temporary equipment 14a (first equipment transmitter 12a) are located on the same floor 23 (same area) (S-3).

[0072] If the position information radio wave (position information data) transmitted from the first worker transmitter 13a and the position information radio wave (position information data) transmitted from the first equipment transmitter 12a are transmitted from the same floor 23 (same area), it is determined that the equipment use position of the first worker 15a and the equipment position of the first temporary equipment 14a are located on the same floor 23 (same area), and if the position information radio wave (position information data) transmitted from the first worker transmitter 13a and the position information radio wave (position information data) transmitted from the first equipment transmitter 12a are transmitted from different floors (different areas), it is determined that the equipment use position of the first worker 15a and the equipment position of the first temporary equipment 14a are not located on the same floor 23 (same area). If it is determined that the equipment use location of the first worker 15a (first worker transmitter 13a) and the equipment location of the first temporary equipment 14a (first equipment transmitter 12a) are not located on the same floor 23 (same area), the Web application server 18 (temporary equipment management system 10) determines that the first temporary equipment 14a is not in operation (not in operation) (operation determination means) (S-4).

[0073] When the Web application server 18 (temporary equipment management system 10) determines that the equipment use position of the first worker 15a (first worker transmitter 13a) and the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) are located on the same floor 23 (same area), the Web application server 18 (temporary equipment management system 10) determines that the equipment use position of the first temporary equipment 14a (first equipment transmitter 12a) that is transmitting a position information radio wave identified by the equipment position identification means and the equipment use position While referring to the equipment use position of the first worker 15a (first worker transmitter 13a) emitting location information radio waves identified by the identification means, the distance between the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) emitting location information radio waves located on the same floor 23 (same area) and the equipment use position of the first worker 15a (first worker transmitter 13a) emitting location information radio waves is measured (distance measurement means) (S-5).

[0074] After measuring the distance between the first temporary equipment 14a and the first worker 15a, the Web application server 18 (temporary equipment management system 10) judges whether the distance between the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) that is transmitting the position information radio wave and the equipment use position of the first worker 15a (first worker transmitter 13a) that is transmitting the position information radio wave is within a preset distance (S-6). If the distance between the equipment position of the first worker 15a (first worker transmitter 13a) and the equipment use position of the first temporary equipment 14a (first equipment transmitter 12a) exceeds the preset distance, the Web application server 18 (temporary equipment management system 10) judges that the first temporary equipment 14a is not in operation (not in operation) (operation judgment means) (S-4).

[0075] When the Web application server 18 (temporary equipment management system 10) determines that the distance between the equipment position of the first worker 15a (first worker transmitter 13a) and the equipment use position of the first temporary equipment 14a (first equipment transmitter 12a) is within a set distance, it measures the duration when the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) that is emitting position information radio waves and the equipment use position of the first worker 14a (first worker transmitter 13a) that is emitting position information radio waves are located on the same floor 23 (same area) (duration measurement means) (S-7).

[0076] After measuring the duration, the Web application server 18 (temporary equipment management system 10) judges whether the duration measured by the duration measuring means is equal to or longer than a preset time (S-8). If the duration when the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) and the equipment use position of the first worker 15a (first worker transmitter 13a) are located on the same floor 23 (same area) is less than the preset time, the Web application server 18 (temporary equipment management system 10) judges that the first temporary equipment 14a is not operating (not operating) (operation judgment means) (S-4).

[0077] The Web application server 18 (temporary equipment management system 10) detects that the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) that is transmitting a position information radio wave and the equipment use position of the first worker 15a (first worker transmitter 13a) that is transmitting a position information radio wave are located on the same floor 23 (same area), and that the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) that is transmitting a position information radio wave and the equipment use position of the first worker 15a (first worker transmitter 13a) that is transmitting a position information radio wave are located on the same floor 23 (same area). If the distance from the equipment use position is within a preset distance and the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) emitting position information radio waves and the equipment use position of the first worker 15a (first worker transmitter 13a) emitting position information radio waves remain located on the same floor 23 (same area) for a set time or longer, it is determined that the first temporary equipment 14a (temporary equipment) emitting position information radio waves is in operation (operation determination means) (S-9).

[0078] In addition, the first temporary equipment 14a (temporary equipment) may be determined to be in operation (operation determination means) only when the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) transmitting the position information radio wave and the equipment use position of the first worker 15a (first worker transmitter 13a) transmitting the position information radio wave are located on the same floor 23 (same area). The first temporary equipment 14a (temporary equipment) may be determined to be in operation (operation determination means) under the condition that the equipment use position of the first worker 15a (first worker transmitter 13a) is located on the same floor 23 (same area) and the distance between the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) emitting location information radio waves and the equipment use position of the first worker 15a (first worker transmitter 13a) emitting location information radio waves is within a preset set distance.

[0079] In addition, if the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) emitting position information radio waves and the equipment use position of the first worker 15a (first worker transmitter 13a) emitting position information radio waves are located on the same floor 23 (same area), and if the equipment position of the first temporary equipment 14a (first equipment transmitter 12a) emitting position information radio waves and the equipment use position of the first worker 15a (first worker transmitter 13a) emitting position information radio waves remain located on the same floor 23 (same area) for a set time or longer, it may be determined that the first temporary equipment 14a (temporary equipment) emitting position information radio waves is in operation (operation determination means).

[0080] The Web application server 18 (temporary equipment management system 10) stops reception of the location information radio waves by the first to fifth receivers 11a to 11e (first to nth receivers) and determines whether to turn off the temporary equipment management system 10 (S-10). If the temporary equipment management system 10 is to be continued in step 10, the process returns to step 1 and the procedure from step 1 is repeated.

[0081] The temporary equipment management system 10 determines whether the equipment position of a specific temporary equipment (1st to nth temporary equipment) that is transmitting a position information radio wave and the equipment use position of a specific worker (1st to nth worker) that is transmitting a position information radio wave are located in the same area, the measured duration is equal to or longer than a preset time, and the distance between the equipment position of the temporary equipment (1st to nth temporary equipment) that is transmitting a position information radio wave and the equipment use position of the worker (1st to nth worker) that is transmitting a position information radio wave is within a preset distance. If the measured duration is longer than a preset time and the distance between the position of the temporary equipment and the position where the worker is using the equipment is within a preset distance, it is determined that the temporary equipment (1st to nth temporary equipment) emitting location information radio waves is in operation, so it is possible to confirm in real time whether various types of temporary equipment used in specified locations (specified areas) of the structure under construction are in operation (in operation) or stopped (not in operation), and the operating status of those temporary equipment (1st to nth temporary equipment) can be accurately grasped.

[0082] If the measured duration is less than a preset time, the temporary equipment management system 10 determines that the temporary equipment (1st to nth temporary equipment) transmitting the location information radio wave is stopped (not in operation), thereby making it possible to exclude short-term non-operational actions such as checking the location and status of the temporary equipment from being in operation. Also, if the measured separation distance exceeds a preset distance, it makes it possible to exclude non-operational actions that are different from actual operation, such as checking the location and status of the temporary equipment from a long distance from being in operation, by determining that the temporary equipment (1st to nth temporary equipment) transmitting the location information radio wave is stopped (not in operation). The temporary equipment management system 10, which determines non-operation based on a set time and distance, can accurately detect the operating status of temporary equipment even under conditions of low communication mesh density. Therefore, this temporary equipment management system 10 can realize efficient use of multiple types of temporary equipment (1st to nth temporary equipment) in structures under construction, and can reduce the costs associated with temporary equipment (leasing fees, rental fees, etc.).

[0083] In step 1, the location information data, reception date and time, receiver identification information (individual identification number or receiver identifier), equipment transmitter identification information (individual identification number or transmitter identifier), and temporary equipment identification information (model number, individual identification number, or temporary equipment identifier) ​​of the location information radio waves of the first to fifth equipment transmitters 11a to 11e are received, the floor 23 (area) on which the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) that are transmitting the location information radio waves are located is identified, and the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) on the floor 23 (area) are identified. The Web application server 18, which has specified the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) in the building specified by the equipment position specifying means, determines whether the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) in the building specified by the equipment position specifying means are on a placement floor (placement area) of the pre-registered temporary equipment, or determines whether the location of the temporary equipment is unknown when the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) registered in advance are specified by the equipment position specifying means (lost / stolen determining means) (S-11).

[0084] If the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) in the building are on a placement floor (placement area) of temporary equipment registered in advance and the locations of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) are clear, the Web application server 18 performs the procedure from step 2.

[0085] If the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) in the building identified by the equipment position identification means are different from the placement floor (placement area) of the temporary equipment registered in advance, the Web application server 18 outputs (displays), for example, a lost message on the display 22 of the personal computer 19 (S-12) and moves the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) to the proper placement floor (placement area). If the location of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) becomes unknown, the Web application server 18 outputs (displays), for example, a lost or stolen message on the display 22 of the personal computer 19 (S-12) and causes measures to be taken to find the location.

[0086] When the positions of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) in a building are different from the placement floor (placement area) of the temporary equipment registered in advance, the temporary equipment management system 10 determines that the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) located on a floor (area) different from the placement floor (placement area) is lost or stolen temporary equipment, and can inform the user that the temporary equipment is lost by, for example, outputting (displaying) a lost message and placing (moving) the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) to the correct placement floor (placement area). When the location of the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) becomes unknown, the temporary equipment management system 10 determines that the missing temporary equipment is lost or stolen temporary equipment, and by outputting (displaying), for example, a lost or stolen message, the system can know that the first to fourth temporary equipment 14a to 14d (first to nth temporary equipment) have been lost or stolen, and can take measures to locate the whereabouts.
