Description

The present invention relates to a computer system that manages rental items.

Many of the construction equipment used at civil engineering and construction sites are rental items, with construction companies renting the necessary number of construction equipment from rental companies for a certain period of time to suit their own work schedules.

Rental companies have been devising ways to rent out construction equipment more efficiently than before in order to prevent construction equipment from being held idle and increasing costs.

For example, Patent Document 1 states, ``The rental company uses the information obtained from the operation recording device and the navigation device, that is, the history of the past operating status and current location of the civil engineering and construction machinery, to identify the registered rental company. It is disclosed that "it is possible to borrow civil engineering and construction machinery that meets the borrowing conditions."

Japanese Patent Application Publication No. 2006-155008

At construction sites, work is carried out in a layered structure between the main contractor and subcontractors, and each construction company often rents the necessary construction machinery, and the site as a whole is working to optimize the rented construction equipment. As a result, the utilization rate of rented construction equipment was sometimes low due to schedule changes. Optimizing unused construction equipment on-site would reduce the number of rental construction machines and reduce costs, but this has not been possible in the past.

On the other hand, if the construction machinery rented at each construction site is optimized, the number of rental machines will decrease compared to before, and the lending side (rental company side) may see a decrease in sales. However, in the past, if rental companies were able to allocate surplus construction equipment to sites where they wanted to lend it but could not due to lack of equipment (losing business opportunities), sales would not decline and construction equipment would be Inventory can also be reduced, but this has not been possible in the past.

However, in Patent Document 1, a rental company connects civil engineering construction companies that wish to borrow civil engineering construction machinery with civil engineering construction companies that are currently renting idle civil engineering construction machinery, thereby improving the utilization rate of civil engineering construction machinery. It is disclosed that

In addition, in Patent Document 1, the owner of the device determines whether the device is idle in advance, registers the idle device with the rental company as available for rent, and the rental company determines whether the device is idle or not. The subsequent rental fee is simply calculated using time and location information (site and storage location).

Furthermore, in Patent Document 1, whether or not rental is possible is only determined based on the rental status from the perspective of the person lending the equipment, such as being rented out, under negotiation, or suspended, and does not take into account real-time information on site. I haven't been able to do it.

Therefore, with the above-mentioned conventional technology, it is complicated and difficult to determine in real time whether or not equipment can be rented in response to changes in the work schedule of the person renting construction equipment at a site where multiple contractors coexist.

In view of the above, in the present invention, for each piece of construction equipment such as a work trolley, construction equipment can be distributed within a site or between sites based on location information within the site, proximity information to other construction sites, and operation information. The purpose of this project is to provide a platform that optimizes construction equipment at each site, optimizes rental equipment, and minimizes construction equipment inventory for rental based on data that visualizes flexibility information.

The present invention provides a rental equipment management system for managing rented equipment using a management server having a processor and a memory, wherein the processor collects operating information of each of the equipment, and the operating information The processor extracts equipment that does not meet operating conditions as flexible equipment, and generates flexible equipment information including geographic information on which the extracted equipment is used, and the processor generates demand information for using the equipment. Upon reception, the geographical information included in the demand information is compared with the geographic information included in the flexible equipment information, and equipment of the flexible equipment information that satisfies predetermined geographic conditions is generated as flexibility information.

Therefore, the present invention makes it possible to visualize construction equipment that is flexible between construction sites based on the operation information of each equipment (construction equipment) used at the construction site (geographical information). It becomes possible to improve the utilization efficiency of construction equipment provided on a rental basis.

<On-site server>
FIG. 3 is a block diagram showing an example of the configuration of a site server 820 at a construction site. The site server 820 collects operation information from the construction equipment 840 and transmits it to the management server 10 of the rental management site 1.

The construction equipment 840 is, for example, an elevated work platform. An acceleration sensor 870, a position sensor 860, and a communication device 850 are installed in the construction equipment 840. The communication device 850 transmits the vibration (operation information) detected by the acceleration sensor 870 and the position information detected by the position sensor 860 to the site server 820 via the network 880.

The acceleration sensor 870 is composed of, for example, a three-axis acceleration sensor, and detects vibrations when a worker works on the elevated work platform. The position sensor 860 is configured with a positioning satellite system such as GNSS (Global Navigation Satellite System), and detects the position of the construction equipment 840.

The site server 820 determines the operating state of each construction equipment 840 from the vibration detected by the acceleration sensor 870, calculates the operating time or operating rate per day as operating information, and transmits it to the management server 10. Note that a value obtained by dividing the operating time by a predetermined time (for example, 8 hours, etc.) can be used as the operating rate.

Note that the timing at which the site server 820 calculates the operation information is not limited to one day, and may be performed at intervals such as one hour or one week depending on the characteristics of the construction site.

The management server 10 stores the operation information for each construction equipment 840 received from the site server 820 in the equipment operation information 320.

Note that although the example above shows the operation information being sent from the site server 820 to the management server 10 of the rental management site 1, the operation information is sent from the site server 820 to the management servers 800-1 and 800-2 of the construction company. However, the management server 800 may compile the operation information of each site and then transmit it to the management server 10 of the rental management site 1.

<Sequence>
The following is an example of a new construction site where the main construction company and subcontractor construction company rent construction equipment from a rental company and manage the operation of the construction equipment using the rental platform of rental management site 1. This is shown in the sequence diagram of FIG.

In the sequence diagrams shown in FIGS. 4 to 7, information is exchanged between the construction company, the rental company, and the rental platform between the management server 800 of the main contractor and subcontractor construction company, the management server 900 of the rental company, and the rental management site 1. An example will be shown in which the management server 10 of FIG.

First, the main contractor and subcontractor construction companies create process information including the process and work details of the construction project on the management server 800 (S1, S2). Next, the management server 800 of the main contractor and subcontractor acquires past performance information 310 from the management server 10 of the rental management site 1 (S3, S4).

The management server 10 aggregates operation information for each construction company from past operation performance information 310, and calculates the number of units ordered for each type and specification of construction equipment for each construction company, process or work content from order performance information 430. Aggregate as information. The management server 10 transmits operation information and order performance information for each construction company to the main contractor's management server 800-1 and the subcontractor's management server 800-2, respectively (S5).

The main contractor's management server 800-1 creates information on the main contractor's planned pile-up of construction equipment to be borrowed from the rental company from the created process information, past operation information acquired from the management server 10, and order history information ( S6). Information on the pile of construction equipment includes the type, specifications, number, and rental period.

The subcontractor's management server 800-2 creates subcontract plan pile-up information for construction equipment in the same way as the main contractor (S7).

The management servers 800 of the main contractor and subcontractor each transmit the created main contractor plan pile information, subcontract plan pile information, process information, and local geographic information of the construction site to the management server 10 (S8, S9).

Next, the management server 10 stores the main contractor's planned pile-up information received from the main contractor into the main contractor's planned pile-up information 210 of the construction equipment pile database 200, and stores the subcontractor's planned pile-up information received from the subcontractor into the pile-up of construction equipment. It is stored in the subcontract plan pile-up information 220 of the database 200.

The management server 10 adds up the information 210 on the pile-up of the number of planned subcontractors and the pile-up information 220 on the planned number of subcontractors, and generates the comprehensive pile-up information 230 for each construction company and each site, as shown in FIG. 8 (S10).

The management server 10 stores the local geographic information received from the management servers 800 of the main contractor and the subcontractor into the local geographic information 510 (FIGS. 13 to 15) of the geographic information database 500 (S11). The management server 10 transmits the comprehensive pile information 230 to the main contractor's management server 800-1 (S12).

The main contractor's management server 800-1 receives the comprehensive pile information 230 and makes adjustments (S13). Note that the comprehensive pile information 230 can be adjusted manually by a user of a construction company or the like.

The main contractor's management server 800-1 transmits the adjusted comprehensive pile information as adjusted comprehensive pile information 240 to the management server 10 of the rental management site 1 and the subcontractor's management server 800-2 (S14).

The subcontractor's management server 800-2 modifies the subcontractor planned number pile information 220 from the pile information related to the construction company of the subcontractor in the received adjusted comprehensive pile information 240, and obtains the revised subcontract plan number pile information 220. (S15).

The management server 10 that has received the adjusted comprehensive pile information 240 and subcontract plan number pile information 220 collates the adjusted comprehensive pile information 240 and the subcontract planned number pile information 220, and then stores the adjusted comprehensive pile information in the construction equipment pile database 200. 240 is stored (S16).

The management server 10 inquires of the management servers 900 of the plurality of rental companies about the inventory status and price of newly rented construction equipment based on the adjusted comprehensive pile information 240 (S17).

The management server 900 of each rental company responds with the inventory status and price to the management server 10 of the rental management site 1 (S18). Based on the response from the management server 900 of the rental company, the management server 10 recommends a procurement source for construction equipment that satisfies predetermined conditions based on inventory availability and price, as shown in FIG. It is generated as a draft 420 (S19). The management servers 800 of the main contractor and subcontractor each acquire the supplier recommendation plan 420 generated by the management server 10 (S20, S21).

Next, in step S30 of FIG. 5, the main construction company requests an estimate from each rental company from the management server 800-1 based on the recommended supplier 420 (S30). The subcontractor management server 800-2 similarly requests estimates from each rental company (S31).

The management server 900 of the rental company creates an estimate based on the request from the construction company (S32), and transmits the estimate to each construction company (S33, S34).

The main contractor and subcontractor construction companies that have received the estimates confirm the details of the estimates, decide on the supplier, and send the details of the order for construction equipment to the management server 10 of the rental management site 1 (S35, S36). . Thereafter, the main contractor and subcontractor construction companies request rental of construction equipment from the determined supplier (S37, S38).

The management server 900 of the rental company that has received the order determines the construction equipment and usage period included in the order.

The management server 10, which has received the order details for construction equipment from the main contractor and subcontractor management server 800, receives the order details from the main contractor and subcontractors as new demand information, and as shown in FIG. Order record information 430 is generated and stored in the supplier database 400 (S40). Note that the demand information may include process information in addition to the order details, or may include information 210 on a pile-up of the number of planned subcontractors and information 220 on a pile-up of the number of subcontractors planned.

Then, the management server 10 generates order record information 430A for each construction company from the order record information 430, as shown in FIG. 11 (S41). Furthermore, the management server 10 generates ordering record information 430B for each rental company from the ordering record information 430, as shown in FIG. 12 (S42).

The management server 10 obtains usage information of construction equipment used at construction sites near the construction site where the construction equipment is borrowed from the order history information 430B for each rental company and the site geographic information 510, as shown in FIG. It is generated as nearby field equipment usage information 260 (S43). Furthermore, the management server 10 generates nearby site equipment usage information 260A for each rental company and construction site, as shown in FIG. 17, from the order history information 430B for each rental company and the site geographic information 510.

The management server 10 extracts the construction process being performed at a nearby construction site from the process work content information 110, and generates nearby site process information 120 as shown in FIG. 20 (S44). Note that the construction site extracted from the process work content information 110 is the same as the construction site included in the nearby site equipment usage information 260.

The management server 10 extracts operation information of construction equipment used at nearby construction sites from the equipment operation information 320 of the construction equipment operation status database 300, and as shown in FIG. 330 is generated (S45). Note that the construction site extracted from the process work content information 110 is the same as the construction site included in the nearby site equipment usage information 260 shown in FIGS. 16, 17, and 18.

As a result, the operation status of construction equipment used at other construction sites near the new demand information construction site is generated as the nearby site equipment operation information 330, and among the construction equipment in the nearby site equipment operation information 330, Construction equipment whose operating rate is less than or equal to a threshold (predetermined operating conditions) can be used as flexibility information.

In step S46, the management server 900 of the rental company receives order record information 430B (FIG. 12) for each rental company from the management server 10 of the rental management site 1, and nearby site equipment usage information 260 (FIGS. 16 and 18). Near field equipment operation information 330 (FIG. 19) and near field process information 120 are acquired.

Then, the transportation cost is calculated by multiplying the distance by the unit price. Then, the management server 10 can determine the company with the lowest transportation cost as the main entity for transportation. Note that the determination of the rental destination and the transportation method are not limited to those described above, and well-known or publicly known techniques can be adopted as appropriate.

Next, the management server 10 generates flexibility information 620 shown in FIG. 24 from the lending source, the borrowing party, and the means of transportation (S60). In addition, when the management server 10 receives a schedule information update request, it updates the flexible period (flexibility 628) of the corresponding construction equipment. Furthermore, the flexible period can be until the rental end date.

The management server 10 notifies the flexibility information 620 to the management servers 800 of the main contractor and subcontractor, respectively. This makes it possible to propose to the main contractor and subcontractor construction companies how to reserve construction equipment while reducing transportation costs.

In step S70 of FIG. 7, the management server 10 generates future forecast information from the past operation performance information 310, equipment operation information 320, process work content information 110, and schedule information update request, as shown in FIG. 710 is generated.

When the management server 10 receives a request to update schedule information, if the content of the update is a change in construction period or work date and time, the management server 10 updates the return schedule 721 of the future forecast information 710 (S71). For each of the construction equipment (equipment No. 717), the management server 10 notifies the construction company of an alarm indicating the return time of the construction equipment a predetermined period before the scheduled return 721 (S72).

This alarm desirably includes the name of the construction site, the name of the construction equipment, the number of construction equipment, and the scheduled return time.

The construction company of the management server 800 that has received the alarm returns the designated construction equipment at the scheduled return time (S73, S74).

The management server 800 of the main contractor and subcontractor stores the name of the returned construction equipment, the name of the construction site, and the equipment number. Then, input of return information including return time is accepted and transmitted to the management server 10 (S75, 76).

The management server 10 acquires operation record information 310 from the return information received from the management servers 800 of the main contractor and subcontractors, updates the operation rate of the past operation record information 310, and calculates the accumulated order record based on the number of construction equipment. The information in the information 250 is updated (S77). Then, the management server 10 ends the process when a predetermined end condition is met.

Through the above processing, it is possible to visualize construction equipment that can be exchanged between construction sites based on the operation information of each construction equipment used at the construction site, and it is possible to visualize the construction equipment that is provided for rental. It becomes possible to improve usage efficiency. Further, by allocating flexible construction equipment from construction sites near the location of the new demand information, it is possible to reduce transportation costs.

In the above sequence diagram, steps S1 to S45 are executed by the planning unit 16, steps S57 to S59 are executed by the accommodation information generating unit 17, and steps S70 and subsequent steps are executed by the updating unit 18.

In addition, in the above embodiment, an example was shown in which the management server 10 of the rental management site 1 notifies each construction company of an alarm when it is time to return the rental, but the present invention is not limited to this. For example, the management server 10 of the rental management site 1 may notify the return time determined in step S71 to the management server 800 of each construction company, and each management server 800 may output an alarm when the return time arrives. .
