Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a system for supporting refueling of a construction machine such as a hydraulic shovel which may be operated in a remote place.

[0002]

2. Description of the Related Art Narrowly defined construction machines such as hydraulic shovels that cannot run on public roads, or construction equipment such as generators that cannot run (hereinafter collectively referred to as construction machines) are self-propelled like automobiles. Can't go to the stand. For this reason, refueling of construction machinery was performed locally by calling a tank lorry (fuel refueling vehicle) each time.

[0003]

Since construction machines sometimes work in remote places such as mountains and remote areas, it takes time to transport fuel to the site by tank lorry. Therefore, when the fuel runs out suddenly, it takes time to arrive at the site by calling the tank lorry, and the operation is interrupted. In order to avoid such a situation, it is necessary for the machine administrator to always keep an eye on the remaining fuel amount of the construction machine and timely grasp it based on information from the construction machine, and to arrange a tank truck.

[0004] However, when there are many construction machines to be managed, the machine manager receives information from all the construction machines directly, and the machine manager always pays attention to the remaining fuel amounts of all the construction machines. If they are attached, there will be too much information, and there is a risk of overlooking construction machines that normally need to refuel. Further, if information is received only when the remaining fuel amount of the construction machine is low, there is a possibility that an oversight due to a communication trouble may occur.

[0005] On the other hand, a refueling company is also called by an administrator of a machine as a customer to deliver a tank lorry to the site. However, since it is called suddenly, there is no schedule or another refueling is completed even if refueling is completed. The customer may be called again to a nearby place where he has just visited, and the operation efficiency of the tank truck is poor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a construction machine refueling support method and a system thereof capable of appropriately refueling a construction machine. Things.

[0007]

According to one aspect of the present invention, there is provided a method for supporting refueling of a construction machine using a management computer capable of communicating with the construction machine. , The construction machine detects information related to refueling, transmits the detected information to the management computer, and the management computer grasps the remaining fuel amount of the construction machine from the received information, and the remaining fuel amount becomes a predetermined amount. It is characterized in that a machine management side for refueling is notified when the following occurs.

According to a seventh aspect of the present invention, there is provided a system for supporting refueling of a construction machine using a management computer capable of communicating with the construction machine, wherein the construction machine includes information related to refueling. And a first communication unit for transmitting the detected information to the management computer, the management computer comprising: a second communication unit for receiving the information transmitted from the construction machine; A remaining amount grasping means for grasping the remaining fuel amount of the construction machine, a determining means for determining whether or not the remaining fuel amount has become a predetermined amount or less, and when it is determined that the remaining fuel amount has become a predetermined amount or less, And a notifying means for notifying a machine management side for refueling.

[0009] In these configurations, the fuel supply information transmitted from the construction machine allows the management computer to ascertain the remaining amount of fuel in the construction machine almost in real time. become,
Work interruption due to running out of fuel is prevented.

[0010] Then, since the management computer notifies the machine management side of the construction machine whose fuel remaining amount is equal to or less than the predetermined amount, the machine management side orders the fuel supply side to supply fuel to the construction machine. Is done. At this time, for a construction machine having a sufficient amount of fuel, the above notification is not made until the remaining fuel amount becomes equal to or less than a predetermined amount. Therefore, even when there are a large number of construction machines to be managed, the machine management side does not become overwhelmed with information, so that oversight of construction machines that should originally be refueled is prevented. In addition, even in the case of a communication trouble, the oversight is prevented because the management computer knows the remaining fuel amounts of all the construction machines from the received information before that.

If the information includes the position information of the construction machine, the position of the construction machine to be refueled can be known, so that it is not necessary to confirm the position. .

If the position information is acquired by using the GPS as in the third aspect of the present invention, highly accurate position information can be obtained even for a construction machine working in a remote place.

[0013] According to the present invention, the information includes time information until the fuel runs out.
By displaying the time until the fuel runs out, the priority of the machine to be refueled becomes clear.

According to a fifth aspect of the present invention, a management computer calculates a refueling route based on information from a plurality of construction machines, and refuels the route according to an order from a machine management side. If there is more than one construction machine that needs refueling, the optimal route should be determined, such as how to deliver the tank lorry to deliver efficiently without running out of fuel in the construction machine. Understand.

If the route is displayed on a map as in the invention described in claim 6, the optimum route can be visually recognized, which is convenient for the delivery of the tank truck.

The remaining fuel amount and the like are grasped, and the necessity of the notification is determined. Then, the machine management side that has received the notification approves the construction machine 1 that is determined to need refueling, and orders the refueling side to refuel the construction machine 1.

The communication satellite 30 is a low-Earth orbit satellite launched in a polar orbit at an altitude of, for example, about 780 km, and once received the operation information of the construction machine 1 transmitted from the transmission unit 184 via the antenna 188. Later base station 32
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, an outline of the information transmission / reception operation of the construction machine 1 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 fuel sensor 26, the position sensor 29 and the like are taken into the machine controller 12, and the information writing means 127 stores the timer 125 in the memory 124 as operation information. (Step S1).

As described above, this operation information is obtained based on output signals from the key switch unit 10, the fuel sensor 26, the position sensor 29, and the like. For example, the operation information from the fuel sensor 26 and the position sensor 29 When the signal is output, the information processing unit 126 calculates the remaining fuel amount and the current position based on the signal, and writes the calculated values.

Next, it is judged by the information judging means 129 whether required information has been prepared as the operation information stored in the memory 124 (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 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 usually transmitted in a state where the data is compressed, and is decompressed when the data is taken into the management computer 20.

If the determination in step S3 is negative, it is determined whether or not command information from the management computer 20 for reading out the operation information stored in the memory 124 and transmitting it to the communication satellite 30 has been received. Is performed (step S7). This determination is executed by the command information decoding means 187. In this determination, the management computer 2
The matching means 186 determines whether or not the identification information transmitted from 0 matches the identification information stored in the ROM 182.
And the discriminating operation is executed only when they match.

If the determination is affirmative in step S7, the process proceeds to step S5, and if the determination is negative in step S7, the process returns to step S1 and the subsequent operations are repeatedly executed. 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, the operation information stored in the memory of the base station 32 is received by the management computer 20 (step S21). At this time, in the present embodiment, it is assumed that reception is automatically performed in order to acquire operation information in almost real time. However, if necessary, the input unit 2
The request signal output from the request signal generating means 209 to the base station 32 by the operation of 03 is transmitted from the transmission unit 213, and the operation information stored in the memory of the base station 32 is read in response to the request signal. You may do so.
Then, 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
Predetermined data processing is performed by the data processing means 211 (step S23), and as a result of this processing, all the construction machines 1
The remaining fuel amount and the like are collectively grasped by the management computer 20. The processing result is displayed on the display unit 202 and is printed out on a recording sheet by the printer 204 as needed, so that the operator of the management computer 20 can easily grasp the result (step S25).

Further, the data processing means 211 determines whether or not the remaining fuel amount has become equal to or less than a predetermined amount (step S27). Side 40 and refueling side 50
At this time, a predetermined notification is made by the notification unit 216 (step S29). The operation information written in the memory 208 is
It is kept held until an erasure instruction signal is output by operating the input unit 203.

Each of the above steps (S1 to S7, S21 to S
The refueling support program for a construction machine constituted by 29) can be recorded on a readable recording medium such as a flexible disk, or can be used by being installed in another computer or the like.

As described above, according to the present embodiment, the information sent from the construction machine 1 is used to
In the case of 0, the remaining fuel amount of the construction machine 1 can be grasped almost in real time, so that the construction machine 1 is supplied with fuel before the construction machine 1 runs out of fuel, so that work interruption due to running out of fuel can be prevented.

Then, the construction machine 1 having the remaining fuel amount equal to or less than the predetermined amount is notified to the machine management side 40, and the machine management side orders the refueling side to refuel the construction machine 1 based on the notification. . At this time, for a construction machine having a sufficient amount of fuel, the above notification is not made until the remaining fuel amount becomes equal to or less than a predetermined amount. Therefore, even when there are a large number of construction machines to be managed, the machine management side does not have too much information, so that it is possible to prevent the construction machine 1 that should originally be refueled from being overlooked. In addition, even in the case of a communication trouble, since the management computer 20 knows the remaining fuel amounts of all the construction machines from the received information before that, the above-mentioned oversight is prevented. As a result, it is possible to appropriately support the refueling of the construction machine 1.

In the above embodiment, the remaining fuel amount and the current position information are calculated by the information processing means 126 from output signals from the fuel sensor 26, the position sensor 29, and the like of the construction machine 1, and the calculated values are used as operation information. However, the output signals from the fuel sensor 26, the position sensor 29, etc. are stored directly in a certain area of the memory 124, read out at an appropriate timing, and read by the information processing means 126, The current position information may be calculated, and the calculated value may be stored again as operation information in an area of the memory 124 that is different from the certain area. In that case, the load on the information processing unit 126 can be reduced by time sharing, and the processing capability can be utilized. Instead of storing the information in the memory 124, the information may be transmitted to the machine management side 40 at the time when the information is calculated.

In the above embodiment, the construction machine 1 calculates the remaining fuel amount and transmits it to the management computer 20. The management computer 20 receives this transmission information and calculates the remaining fuel amount of all the construction machines 1. The fuel consumption detected by the construction machine 1 is directly transmitted to the management computer 20, and the management computer 20 receives the transmission information and calculates the remaining fuel amount of the construction machine 1. ,
The remaining fuel amount of the construction machine 1 may be determined from the calculated value. This also makes it possible to reduce the load on the information processing unit 126 and utilize its processing capability.

In the above embodiment, the position sensor 29
However, depending on the distance between the construction machine 1 and the management computer 20, for example, a simple positional information system using a mobile phone and a personal computer may be used.

In the above embodiment, in order to grasp the remaining fuel amount of the construction machine 1, the data processing unit 211 of the management computer 20 displays the remaining fuel amount and the like on a map on the screen of the display unit 202. Although the data processing is performed, the data processing may be performed such that the data can be displayed on a small screen of the portable terminal such as the notification unit 216. In that case, the fuel supply route is directly transmitted to the tank lorry on the fuel supply side, and the route setting / change is performed according to the operating information that changes every moment, thereby enabling more efficient operation.

In the above-described embodiment, even in the case of a communication trouble, the remaining fuel amounts of all the construction machines 1 are grasped by the management computer 20 from the received information before that, and further based on the grasped contents. The management computer 20 may be able to predict the subsequent decrease in the remaining fuel amount of all the construction machines 1. For example, based on the remaining amount of fuel before the occurrence of a communication trouble, the above-described decrease amount can be estimated by performing linear interpolation by extrapolation. In that case,
Each construction machine is replenished with fuel before running out of fuel, and work interruption due to running out of fuel is reliably prevented.

Further, even if there are many construction machines to be managed, it is possible to eliminate oversight of construction machines that originally need to be refueled, and also to avoid oversight even in the case of a communication trouble. As a result, it is possible to support appropriate fuel supply to the construction machine.

According to the second aspect of the present invention, there is no need to confirm the position, so that it is possible to support efficient fuel supply.
