Description

  The present invention relates to a construction machine rental management system and a construction machine rental management method for renting a construction machine.

Conventionally, the rental fee for construction machinery is based on the period (number of days) from the loan date to the return date when the rental period is short, and according to a prior contract such as monthly or annual in the long term In general, a fixed fee system was adopted.
Therefore, if the rental period is short, rental fees will be incurred regardless of usage. For this reason, the user must return the construction machine every time it is used to avoid incurring a rental fee even when it is not in use, and if the use becomes necessary, borrow it again. I had to take it. In addition, when it is unused due to weather, process, etc., the rental company may be forced to reduce the price according to the request of the user, which is complicated for the rental company.
In addition, when the rental period is long, the fixed rate structure is adopted mainly because it is difficult to grasp the amount of construction machinery used. It was not possible to meet the needs.

An example of the process table data is shown in FIG. The process chart data shown in FIG. 9 includes a user ID that is user identification information, a work type ID that is identification information of a type of construction or special event, industrial zone information that indicates a place (technical zone) where the construction or special event is performed, construction or special event. And period information indicating the period of time, and machine ID which is identification information of the construction machine 140 necessary for construction and special events.

  Among these, the user ID is assigned to the user in advance. On the other hand, the work type ID, the work section information, and the period information are set based on information shown in the process chart. The machine ID is the machine ID of the construction machine 140 requested by the user. Alternatively, the machine ID is the machine ID of the construction machine 140 that the operator of the rental company has determined to be necessary based on the type of work or event, the size of the work area, and the period of the work or event shown in the process chart. .

The rental management server 200 acquires the process chart data from the input unit 206 and registers it in the rental management information DB 208. The construction machine 140 to be leased is specified by the process chart data. A person who performs the lending procedure in the rental company specifies the construction machine 140 to be leased based on the process chart data. Furthermore, the person who performs the lending procedure in the rental company stores the specified construction machine 140 in the storage unit 100 and lends it to the user.
Thereafter, each time a rental fee calculation period (for example, one month) elapses, the rental company operator inputs the totaled result data based on the acquired totalized result. Here, the total result data is the information stored in the machine-specific count meter 138 of the operation management device 130 described above, that is, the machine ID and the count value for each construction machine 140 (the construction machine 140 is continuously used for 10 minutes or more. Days of operation). For example, a worker of a rental company inspects the operation management device 130 for each rental fee calculation period and acquires a total result.

When the CPU 134 in the operation management device 130 shown in FIG. 7 outputs the count information in the machine-specific count meter 138 to the communication unit 132, and the communication unit 132 transmits by wireless communication, the rental management server 200 You may make it receive the total result data from the operation management apparatus 130. FIG. Furthermore, the rental management server 200 generates data (rental fee calculation data) used for calculating the rental fee based on the total result data. Specifically, the rental management server 200 extracts the machine ID included in the input total result data. Furthermore, the rental management server 200 extracts the user ID, the work type ID, and the work zone information associated with the extracted machine ID from the process table data in the rental management information DB 208. Then, the rental management server 200 generates the rental charge calculation data by associating the count value included in the aggregation result data with the extracted machine ID, user ID, work type ID, and work area information as shown in FIG. . Here, if the count information in the machine-specific count meter 138 of the operation management device 130 is not reset to the initial state for each rental fee calculation period, the count value included in the aggregation result data exceeds the rental fee calculation period. Is the integrated value. For this reason, the rental management server 200 stores the count value included in the aggregation result data acquired last time, and calculates the count value included in the aggregation result data acquired last time from the count value included in the aggregation result data acquired this time. By subtracting, the count value corresponding to the rental charge calculation period is calculated and used for the rental charge calculation data.

  Thereafter, the rental management server 200 calculates a rental fee at a predetermined timing. Specifically, the rental management information DB 208 corresponds in advance to the machine ID of each construction machine 140 as shown in FIG. 11 and the rental unit price (unit price on the day when the construction machine 140 has been continuously operated for 10 minutes or more). The attached information (unit price information) is registered. The rental management server 200 acquires a unit price associated with the machine ID included in the rental charge calculation data from the unit price information, and uses the acquired unit price and the count value included in the rental charge calculation data. By multiplying, the rental fee for each construction machine 140 is calculated. The calculated rental fee information is stored in the rental management information DB 208.
