DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the technical field of a logistics system in building construction.

[0002]

2. Description of the Related Art There are various types of construction work, such as steel door work, air conditioning work, aluminum sash work, light iron work, board work, sanitary equipment work, and ceiling work. We are carrying in work. 2. Description of the Related Art Conventionally, in construction management in building work, a management office at a building site has been planning and managing an order for labor and materials and equipment based on a monthly schedule. The process plan and inventory management used at this time are mainly created by the staff in the form of a process schedule, and based on them, the specialized construction contractors are notified of the arrangement of labor, production instructions of materials and equipment, orders and receipts, Further, logistics management such as the date of loading and unloading is performed by a specialized construction contractor contacting the transport contractor by telephone, facsimile, partial e-mail, or the like.

[0003]

However, in the above-mentioned construction and logistics management, the above-mentioned series of operations are performed independently of each other. This has led to erroneous arrangements due to incorrect orders received by contractors.

[0004] Also, the construction site is limited due to space constraints.
The necessary materials and equipment must be brought in each time, and the specialized construction contractor requests the transporter on the necessary day of delivery, and as a result, it is difficult to transport the equipment and equipment in a truck full state and the logistics becomes difficult. The efficiency was significantly reduced. further,
In certain professional works, there are cases where the equipment and materials are distributed to multiple specialized contractors, and since the specialized equipment is transported separately to the building site from each specialized contractor, it takes time and effort to manage the equipment and equipment. Have.

[0005] In recent years, the daily miscellaneous goods industry has opened a commerce site on the Internet web and started e-commerce, and the construction industry has also started e-commerce. It has been replaced. However, the information required on the web as described above, such as production information such as process and material inventory information, work progress information and cost, should be released in the early and evening, and operated so as to correct the above problems. Is inevitable. For that purpose, a system is required that can monitor necessary information by linking production information such as inventory information of materials and equipment, work progress information and costs, mainly on the process schedule.

Furthermore, in recent years, in consideration of the impact on the global environment, it has been necessary to more actively promote the reduction of industrial waste and the recycling of materials in construction work than ever before. The need for green logistics is increasing. Services related to green logistics, specifically, sorting of garbage on site, return of remaining materials, arrangement of trucks for material recycling, etc. are increasing. In addition, management work related to intravenous logistics, including the return of temporary materials, is a considerable burden on staff. On the other hand, the loading rate of trucks often focuses only on loading to the site, and at present, the loading efficiency of flights returning from the site is not always satisfactory.

[0007] The present invention solves the above-mentioned problems and problems in the prior art, and as a whole, includes smoothing work, shortening the construction period, improving quality and reducing costs, and further taking out materials from the site. It is an object of the present invention to provide a logistics system in building construction that can improve the logistics efficiency of a building.

And share information. At the work site via this web server, you can create a construction schedule, check the ordering of transporters and specialty contractors, check inventory information, publish work results, send information on requests for materials and labor, and produce Perform gender evaluation and release of evaluation information, check reference logs, etc.

[0011] For specialized construction companies such as steel door construction, air conditioning construction, aluminum sash construction, light iron construction, board construction, plumbing and sanitation facilities construction, and temporary material construction, collection and confirmation of construction progress information via a web server. Notification, collection request transmission, collection request reception and confirmation notification, material and labor supply planning and notification, production completion notification, collection request, etc. are performed.

[0012] In the transportation company, collection of collection information, vehicle allocation plan, collection notice, inventory confirmation,
Notification and transmission of various information are performed. It is also possible to monitor the operation status of trucks, but it is not necessarily real-time. For example, an IC card capable of recording GPS information can be automatically input to a computer every day.
Employing a system that can be linked to map information enables more efficient operation.

FIG. 2 shows a screen of a computer provided at a work place, a transport company and a specialized construction company, and shows a process chart including a process plan, inventory management information and distribution management information. The weekly schedule of the process chart is created for a plurality of weeks every week. Weekly schedules are initially created by shop clerks, but subsequent changes are made by the staff and associated vendors. Access information to the weekly schedule and records of changes (by shop and vendor) are assured by logging. These logs are displayed by clicking the date, and are also used for prompting when a person who needs confirmation does not refer to the log.

A carry-in command and an order command are automatically output, and confirmation information is automatically returned. In addition to the usual construction work (scheduled work date column), the process schedule displays a material transferable date column and a required transfer date (a circle) that must be entered by that date. Each schedule has the following links.

[0015] Construction work: labor order, material consumption status and production information based on it (for example, information on how many doors are to be made by date), inventory management information Carryable date: provision of information to the dispatcher's dispatch plan, Notification of production completion from the manufacturer, inventory management information Required delivery date: vehicle allocation plan, production schedule at the manufacturer And when you click on the relevant part of the weekly process chart, the file linked above is displayed, and the relevant contractor is the necessary information Can be obtained.

Next, a process of preparing the process chart of FIG. 2 will be described with reference to FIGS. FIG. 3 shows a screen for creating a process chart created at a work place. Here, the rebar construction will be described. Columns for columns / walls, beams, slabs, columns / walls / beam formwork, deck laying, concrete construction, etc. scheduled work date column (black frame) and material importable date column (grid pattern frame) Is prepared, and the desired date of material delivery of pillar and wall arrangements, which is the first construction (necessary date of delivery, black triangle), is entered. Clicking on the frame in the material transferable date column displays a stock information input screen, in which the stock amount of the material is input. The information of this schedule is shared between the workplace, the transport company and the specialist contractor via the server, and the transporter and the specialist contractor perform the task (work) and material delivery planning according to the schedule. Will be drafted.

FIG. 4 shows a transmission screen of a carry-in date adjustment request made by the carrier, and the carrier sees the above-mentioned process chart and instructs a special contractor of each construction to supply a material name, a material quantity, and a possible date of carry-in. contact. FIG. 5 shows a reception screen on the side of the specialized construction company, and the specialized construction company inputs a desired date in a column for a desired carrying-in date. FIG. 6 shows a receiving screen on the carrier side, in which a list of tasks of each specialized construction company and a desired date of carrying in is displayed. When the desired carrying-in date is determined in this way, as shown in FIG. 7, black triangles are inserted in the beam arrangement in the process chart.

The carrier informs each specialized construction contractor of the possible date of carrying in accordance with the adjustment request and determines the desired carrying date. At this time, the weight and the loading capacity of each material are registered in the database in advance, and if there is a vacancy in the truck, a request is made to each specialized construction contractor to change the desired delivery date so as to fill the vacancy. In this way, the transportation plan is made so that the truck is as full as possible. In addition, when a certain facility and a mounting member of the facility are different professional construction contractors, a transportation plan is made so that both are delivered as one package.

FIGS. 8 and 9 show another embodiment of the present invention. FIG. 7 is a diagram for explaining a process chart, and FIG. 8 is a diagram showing a process chart in which a carry-in date and a carry-out date are determined. It is.

As shown in FIG. 8, the working process (black frame)
Before the period (the frame with a lattice pattern), while after the work process (the black frame) the period during which the product can be carried out (the hatched frame)
Is displayed, and, similarly to the above-described embodiment, after adjustment between the work site, the specialized construction contractor, and the transportation company, the desired carry-in date and the desired carry-out date are determined within these periods. As shown in FIG. Black triangles and circles are automatically plotted on the itinerary. According to the present embodiment, it is possible to improve the distribution efficiency as a whole, including unloading of materials from the site, and it is possible to reduce work load such as unloading adjustment and arranging trucks.

By the way, in practicing the present invention,
It is important to accurately grasp the loading ratio of transport vehicles.
In this regard, conventionally, the situation of the cargo has been observed by a person on the spot, or the situation of the loading of the transport vehicle has been recorded by a video camera, and the image has been investigated by the person at a later date. In the method of (1), it is necessary for a person to always be on site and observe.In the latter method, since only the transportation vehicle is searched for and observed, after all, all images are observed. It takes a lot of time and is not an efficient survey method. In addition, any method can only measure the volumetric loading rate obtained from the volume of the load occupying the loading platform. The weight loading ratio has been investigated from hearings from material manufacturers and drivers and the weight stated on the slip, but the weight of the material is very low on the slip, and even the material maker has the material Since there are many cases where the weight of the vehicle is not known, it is very difficult to measure the weight loading ratio.

FIG. 10 shows another embodiment of the present invention.
FIG. 2 is a system configuration diagram for describing a loading ratio measurement system for solving the above problem.

After the transportation vehicle that performs the unloading operation at the material unloading place, three cameras are installed in advance laterally and upwardly,
One of the cameras is connected to the image change detection device. The image is always captured by the image change detection device, and when a transportation vehicle enters the material unloading place, if the image changes more than a certain level,
The image change detection device sends a signal to the image processing device and the weighing device.

In response to the signal, the image processing apparatus starts capturing images from all cameras. The image processing device operates the image processing device for the image captured from each camera, recognizes the vehicle registration number, the type of the transported vehicle, the volume of the loading platform, the maximum loading weight, and the volume of the loaded material. Is measured. At the same time, the weighing device measures the weight of the vehicle including the loaded materials before unloading the materials.

After the material is dropped off at the material unloading place, the image change detecting device also sends a signal to the image processing device and the weight measuring device when the vehicle leaves (a change that exceeds a certain level occurs in the image). send. Upon receiving the signal, the image processing device captures the image of each camera again, activates the image processing device to check whether or not the material remains on the carrier, and if so, measures the volume of the material and at the same time measures the weight. The measuring device measures the weight of the vehicle after unloading the material.

From the above measured data, the volume loading rate of the transport vehicle is calculated from the capacity of the loading platform and the maximum loading capacity when the vehicle enters, and the weight loading rate is calculated from the volume and weight of the loading when entering and exiting the vehicle. All these data are recorded in a database. After that, when entering the same vehicle, when the vehicle registration number is first read by the image processing device, the vehicle type, the volume of the loading platform, and the maximum loading weight are read out by collating with the vehicle registration number in the database. Therefore, the efficiency of the image processing function and the time can be reduced.

It should be noted that the images of each camera from when the vehicle enters to when the vehicle exits are all recorded with the time by the image change detecting device or a separately installed recording device.
These images can be used as they are for the work analysis of the material loading work.

The image change detecting device, the image processing device, the image recording device, the database, and the like constituting the present system can be constructed by preparing a device (computer) that individually fulfills each function. However, some or all of the devices may be collectively mounted on one device (computer).

According to the loading rate measuring system described above,
The volume loading rate and weight loading rate of construction material transportation vehicles, which were difficult to obtain in the past, can be automatically measured in real time without human involvement, and can be applied to various and various construction sites. By doing so, it is possible to easily obtain a large amount of data according to various conditions such as the purpose and scale of the building. Further, the loading status of the material transport vehicle, which could not be easily grasped in the past, can be easily measured, and can be used as a material for grasping and reducing the transport cost of the construction material. Further, the work analysis of the material carrying-in work can be performed without human observation on the spot.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, in the above embodiment, the logistics system at one construction site has been described, but a network may be formed between a plurality of construction sites.

[0031]

As is clear from the above description, according to the present invention, mistakes and omissions in logistics are eliminated.
The construction can be performed smoothly and the construction period can be shortened. Also, because the publicity of information will increase competition,
Cost reduction, quality improvement, and cost transparency can be achieved. In addition, since the loading / unloading information and process information are promptly transmitted, the traders can arrange production orders and labor, and even these fluctuations systematically, and provide high-quality labor at an appropriate price. can do. Also,
Since many work sites can be contacted in one day, labor costs and material costs can be reduced by greatly improving transportation efficiency and thereby reducing costs. In addition, labor information and equipment information can be obtained for a long period of time, and seasonal changes in labor and equipment can be systematically dealt with, enabling smooth construction management. Further, the burden of the staff on the contact work and the adjustment work is greatly reduced, and the work can be improved.
