Description

{Circle over (1)} The present invention relates to a deployment planning device and a system at each base for construction equipment such as a hydraulic shovel rented from each base such as a rental company.

For construction machines such as hydraulic excavators used at construction sites, for example, required models and specifications greatly differ depending on the type of work and the like (for example, see Patent Document 1). Therefore, it is more economical to rent from a rental company than to purchase and use construction machines. For this reason, rental of construction machines has been rapidly progressing in recent years.

Rental companies usually have a plurality of sales offices, and with the rapid progress of rental, the only plan for increasing the number of construction machines to each sales office is to increase the number of sales offices.

In these configurations, the number of construction machines deployed at each site is stored in advance for each site, for each model of construction machine, and for each specification of the construction machine. The operating time is collected for each construction machine, and the collected operating time is totaled for each site, model, and specification of the construction machine, and the operating time totaled for each site, model, and specification Is divided by the number of construction machines for each site, model, and specification, so that the operating rate per construction machine is calculated for each site, model, and specification. The utilization rate calculated for each specification is presented, so the efficiency of each type of construction machine and each specification owned by each site such as a rental company is quantitatively grasped, and Is easy to determine what is So as to.

By the way, the rental fee for construction equipment is sometimes charged on an operating time basis, and this operating time has conventionally been collected individually by a borrower's self-declaration or an IC card set in the construction equipment. In this case, it is difficult to perform a highly accurate deployment plan of the construction machine because the operation time of the construction machine working in a remote place is not collected in a timely manner.

Therefore, as in the invention according to claim 7, a system including a construction machine and the device according to any one of claims 1 to 6, which can communicate with the construction machine,
The construction machine includes a detection unit that detects operation information that is information regarding operation, and a transmission unit that transmits the operation information detected by the detection unit to the device.

I decided.

In this case, the construction machine detects operation information, which is information relating to operation, and transmits the detected operation information to the apparatus according to any one of claims 1 to 6. Then, on the device side, the operation information transmitted from the construction machine is received, the operation time of the construction machine is calculated based on the received operation information, and the calculated operation time is calculated by the operation time collection unit. Collected. Therefore, the operation time of the construction machine used in a remote place is collected in a timely manner on the device side, and a more accurate and appropriate deployment plan of the construction machine is made using this.

According to the inventions set forth in claims 1 to 6, it is possible to quantitatively grasp the efficiency of each type of construction machine and each specification owned by each base such as a rental company, and what types and specifications to invest. Can be easily determined. Also, from the efficiency of each base, the construction machines deployed at each base can be rearranged between the bases so as to improve the rental profit. In this way, an appropriate deployment plan of construction machines at each site such as a rental company can be made, and the rental profit can be improved.

Furthermore, instead of predicting, for each rental company, construction machinery to be resold or used to increase the number of machines to be deployed, based on the efficiency of each model, each specification, or each base, or from its transition. In addition, since the construction machine manufacturer or the like can collectively analyze, predict, and provide information, the burden on the rental company and the like can be reduced in terms of cost and accuracy.

According to the seventh aspect of the present invention, since the operation time of the construction machine used in a remote place is collected in a timely manner on the device side, the demand and supply of the construction machine to be rented by using this are quantitatively determined. In this case, a more appropriate construction machine deployment plan can be made, and rental profits of rental companies and the like can be improved.

In the present embodiment, the operation information of the construction machine 1 is temporarily stored in the memory 124 and transmitted to the management computer 20 via the satellite communication 30 as described above. In the management computer 20, based on the received information, the engine start date and time and the engine stop date and time are displayed on the monitor screen of the display unit 202 in a table format as shown in FIG. It is supposed to be. In the figure, the time measured by the hour meter 24 is displayed in association with the engine start date and time and the engine stop date and time. Of course, it is also possible to display the engine total operating time and the like and to print out. From the engine start date and time and engine stop date and time on the monitor screen obtained in this way, the correct operation time (number of days used) within a predetermined period is collected for each construction machine.

The collected operating times are totaled for each model, specification, and business office of the construction machine 1, and the total operating hours for each model, specification, and business office are calculated for each of the above-described types of construction machine and each specification. Then, by dividing by the number of units of each sales office, the operating rate of each model, each specification, and each office per construction machine is calculated. For example, FIG. 3 shows the number of construction machines 1 rented from each office within a predetermined period by model, FIG. 4 shows the operation time by model, and FIG. 5 shows the operation rate by model. Also, the value of each rental office is shown. In the figure, the number of construction machine models “SK20SR” rented from the sales office A is seven, and its operation time is 714 hours, so that the operation rate is 102 hours / unit. From the operating rates on the monitor screen obtained in this way, differences between models and between offices are clarified.

(4) The calculated occupancy rates are presented to the rental company. At this time, the occupancy rates are graphed for visual effects and the like. For example, FIGS. 6 and 7 show graphs of the operating rates by model. In FIG. 6, the operating rate of each type of the sales office A is shown. From the figure, the operating rate of the model “SK75UR” of the construction machine 1 is the highest in the office A and the lowest is the type “SK35SR” of the same type. You can see that there is. FIG. 7 shows the total occupancy rates of the respective offices by model. From FIG. 7, the total occupancy rate of the sales office A is the highest, and the total occupancy rate of the office D is the lowest. In addition, it can be seen that the differences in the operating rates by model between the offices are almost the same.

(4) When a specific model of the construction machine 1 rented from each business office within a predetermined period has a plurality of specifications, it is also possible to calculate an operation rate for each specification. For example, FIG. 8 shows the number of models “SK60SR” by specification, FIG. 9 shows the operation time by specification, and FIG. 10 shows the operation rate by specification. It is shown. In the figure, the number of the standard (STD) specifications of the model “SK60SR” of the construction machine 1 rented from the sales office A is four and its operation time is 276 hours, so that the operation rate is 69 hours / It is a stand. From the operating rates on the monitor screen obtained in this way, differences between specifications and offices are clarified.

(4) The calculated occupancy rates are presented to the rental company. At this time, the occupancy rates are graphed for visual effects and the like. For example, FIG. 11 shows a graph of the operating rate of each specification of the sales office A. From the same figure, the operating rate of the high-reach specification of the model “SK60UR” of the construction machine 1 is the highest in the sales office A, and the STD It turns out that the specifications are the lowest.

コ ン サ ル タ ン ト Then, based on the operating rates of each model, each specification, and each office, consultant information such as used resale or an increase in the number of deployed machines is proposed to the rental company via the notification unit 223. 12 to 14 are screen examples showing the following proposal contents.

(1) Consultant information on construction machines to be increased and construction machines to be resold: For example, the target operation rate Km of the construction machine 1 is set to 100 hours / month, and the ratio of the target operation rate to the average operation rate is R. If R <0.8, resell the vehicle. If 0.8 ≦ R ≦ 1.2, keep the current condition. If R> 1.2, increase the number of vehicles. As shown in FIG. 12, the number of units after and after the deployment review is displayed on the monitor screen as the new and old units. In this case, a total reduction of 44 construction machines 1 is proposed as consultant information.

(2) Construction machine relocation consultant information for each sales office: For example, as for the model “SR20SR” of the construction machine 1, the number of allocations for each sales office is as shown in FIG. The new and old numbers are displayed at the top and bottom of the monitor screen. In this case, the relocation plan is proposed as consultant information.

(3) Consultant information on construction machines to be increased and construction machines to be resold for each specification: Target operating rate is 100 hours, and machines with operating rates less than 0.8 are resold and operating rates from 0.8 Assuming that the models up to 1.2 remain the same as the current ones, and those with an operating rate exceeding 1.2 increase the number of vehicles, the model “SK60SR” has the number of vehicles after and after the deployment review as shown in FIG. The new and old numbers are displayed on the monitor screen. In this case, resale and increase of vehicles for each specification machine are proposed as consultant information.

The communication satellite 30 is, for example, a low-orbit orbit satellite launched in a polar orbit near an altitude of 780 km, and after receiving operation information of the construction machine 1 transmitted from the transmission unit 184 via the antenna 188 once, the base station. The base station 32 stores the operation information of the construction machine 1 transmitted via the communication satellite 30 in a memory allocated to the management computer 20.

Next, the outline of the information transmission / reception operation on the construction machine 1 side in the system configured as described above will be described with reference to the flowchart shown in FIG.

That is, when the engine of the construction machine 1 is started, output signals from the alternator 22, the hour meter 24, and the like are taken into the machine controller unit 12, and the date and time from the timer 125 are stored in the memory 124 by the information writing unit 126 as operation information. It is written together with the information (step S1).

The operation information is obtained based on output signals from the key switch unit 10, the alternator 22, the hour meter 24, and the like, as described above. For example, a “START” signal is output from the key switch 103, and The time when the engine is started and the power generation signal is output from the alternator 22 is written as the engine start date and time, the "ON" signal output from the key switch 103 disappears, and the power generation signal output from the alternator 22 disappears. Is written as the engine stop date and time.

Next, the information amount determining means 127 determines whether or not the information amount (data amount) of the operation information stored in the memory 124 is equal to or more than a predetermined amount (step S3). If the determination is affirmative, the operation information stored in the memory 124 is read by the information reading means 128 and transmitted to the communication satellite 30 via the antenna 188 by the transmission section 184 (step S5). The remaining storage capacity may be calculated from the total storage amount of the operation information, and the operation information may be transmitted to the communication satellite 30 when the remaining storage capacity becomes equal to or less than a predetermined amount.

The operation information transmitted to the communication satellite 30 is transmitted to the base station 32 and stored in the memory of the base station 32. The operation information is normally transmitted in a state where the data is compressed, and is decompressed when the data is taken into the management computer 20.

If a negative determination is made in step S3, it is determined whether or not command information from the management computer 20 to read out the operation information stored in the memory 124 and transmit it to the communication satellite 30 has been received (step S3). Step S7). This determination is performed by the command information decoding means 187. In this determination, the matching means 186 checks whether the identification information transmitted from the management computer 20 matches the identification information stored in the ROM 182. , The discriminating operation is executed only when they match.

と If the determination is affirmative in step S7, the process proceeds to step S5. If the determination is negative in step S7, the process returns to step S1 and the subsequent operations are repeatedly performed. When the operation information is transmitted to the communication satellite 30 in step S5, the operation information stored in the memory 124 is deleted.

Next, the outline of the information transmission / reception operation on the management computer 20 side in the system configured as described above will be described with reference to the flowchart shown in FIG.

First, by operating the input unit 203 at a fixed time every day, the operation information stored in the memory of the base station 32 is received by the management computer 20 (step S21). That is, the request signal output from the request signal generator 209 to the base station 32 by the operation of the input unit 203 is transmitted from the transmission unit 213. The operation information stored in the memory of the base station 32 is read in response to the request signal, and the read operation information is transmitted from the base station 32 to the management computer 20. The transmitted operation information is received by the receiving unit 214, and written into the memory 208 by the information writing unit 210 together with the identification information.

The operation information written in the memory 208 is subjected to the above-described predetermined data processing by the data processing means 211 (step S23), and as a result of this processing, all the construction machines 1 are classified by model, specification, and sales office. The operation time and the operation rate for each operation are collectively grasped by the management computer 20, and each proposal is made based on this operation rate. The processing result is displayed on the monitor screen of the display unit 202, and is printed out on recording paper by the printer 204 as necessary (step S25). Then, each proposal is transmitted to the rental company side 40 via the notification unit 223 (step S27). The operation information written in the memory 208 remains held until an erasure instruction signal is output by operating the input unit 203.

If the operation information stored in the memory 124 of the construction machine 1 does not reach the predetermined amount, the operation information is not transmitted to the base station 32, so that the management computer 20 transmits the operation information. Therefore, the management computer 20 cannot receive the operation information. In such a case, if necessary, the command information output from the command signal generating means 211 by operating the input unit 203 is transmitted from the base station 32 to the construction machine 1 via the communication satellite 30 by the transmission unit 213.

The construction machine deployment planning program composed of the above steps (S1 to S7, S21 to S27) may be recorded on a readable recording medium such as a flexible disk, or may be installed on another computer or the like for use. it can.

As described above, according to the present embodiment, the operation time of the construction machine 1 used in a remote place is collected in a timely manner on the management computer 20 side. This makes it possible to quantitatively grasp the operating rate of each type and specification of the construction machine 1 owned by each office of the rental company, and to easily determine the type and specification to be invested. Become like In addition, from the occupancy rate of each business office, the construction machines 1 deployed in each business office can be rearranged between the business offices so as to improve the rental profit. In this way, an appropriate deployment plan of the construction equipment at each office of the rental company is made.

In the above embodiment, the case where the management computer 20 is owned by a construction machine maker is described. However, even if the management computer 20 is owned by a rental company itself or a machine management company, etc. Good. However, when the owner of the management computer 20 is the rental company itself, the presentation content displayed on the monitor screen of the display unit 202 can be directly confirmed, so that it is not particularly necessary to provide the notification unit 223.

Further, in the above embodiment, the operation information detected by the construction machine 1 is temporarily stored in the memory 124 and then transmitted to the management computer 20, but the operation information is transmitted to the management computer 20 without passing through the memory 124. 20 may be directly transmitted, in which case a simple system can be configured.

Further, in the above embodiment, the operating rate is calculated for each model, specification, and rental office of the construction machine 1, but the operating rate may be calculated for at least each office of the construction machine 1. Alternatively, in addition to this, the operation rate may be calculated for each model or each specification. In that case, a simpler system can be configured.

In the above embodiment, the management computer 20 acquires the operation information of the construction machine 1 via the communication satellite 30. However, depending on the distance between the work site of the construction machine 1 and the management computer 20, By using simple wireless communication or a portable terminal instead of the communication satellite 30, a simpler system can be configured. Further, the operation information of the construction machine 1 may be obtained by a declaration or an IC card without using any communication means, as described in the conventional example. In that case, a simpler system is configured.

Further, in the above embodiment, the example in which the rental company owns the construction machine is shown, but the construction machine from which the information is collected may be the one owned by the construction machine maker, or the construction company May be owned by

In the above-described embodiment, the example in which the construction machines are deployed in the office of the rental company is shown. However, it is not necessary that the office is a separate office, and a simple garage may be used as long as it is a base. Further, information may be collected by regarding a plurality of sales offices as one base.

Further, in the above embodiment, the operating time is collected to calculate the operating rate. However, instead of the operating time, the lending time may be collected and the deployment plan may be presented. For a rental company, the lending time is more important than the time during which the user operates the construction machine, so using the lending time may be desirable in terms of efficiency. In this case, the lending rate is calculated instead of the occupancy rate. In short, it is only necessary to be able to present data indicating the rental efficiency, and the value indicating the efficiency may be a lending rate or an occupancy rate. In addition, as a method of collecting the lending time, a tool such as a taxi meter indicating that the lending is in progress may be attached to the construction machine, or the data may be manually input. Further, the current position of the construction machine may be detected using a GPS system or the like, and may be calculated based on the time when the construction machine is at the site, or may be calculated based on the time when the construction machine is not at the parking lot. Good.
