In the operating room 11 of this building machinery, be provided with the display equipment 22 that shows engine condition etc.At this, so-called engine condition for example refers to, the temperature of engine cooling water, engine oil temperature, residual fuel amount etc.In addition, this display equipment 22 is arranged on the bottom of the vertical frame 25 of the front window 23 that distinguishes operating room 11 and a side window 9, is provided with display picture 26 and operation in the front of shell 24 with button 27 ...In addition, this display picture 26 for example is made of TFT LCD.
As shown in Figure 3, building machinery comprises control circuit shown in Figure 3.And, the specific fuel consumption of the specific fuel consumption of analytical unit time in this control circuit (below be referred to as the time fuel consumption) or fundamental operation amount (below be referred to as the operation fuel consumption).In display unit 30, show the time fuel consumption measured and setting the time fuel consumption difference or demonstration to the understanding of the difference of the time fuel consumption of the time fuel consumption measured and setting is provided.This control circuit comprise fuel consumption with detection device 31, workload detection device 32, be transfused to the checkout value that detects by each detection device 31,32 arithmetic unit 33, be transfused to the control gear 34 of the operation result of arithmetic unit 33, setting device 35 that the goal-setting value of time fuel consumption and the goal-setting value of operation fuel consumption (target fuel consumption) are set etc.In addition, display unit 30 is made of described display equipment 22, the difference of the described time fuel consumption that demonstration is measured on this display picture 26 and the time fuel consumption of setting etc.
Promptly, this display equipment 22 constitutes display unit 30, this display unit 30 except showing described engine condition, also can show the difference etc. of operation fuel consumption (goal-setting value) S2 of operation fuel consumption (practical measurement value) B of poor or mensuration as shown in Figure 5 of time fuel consumption (goal-setting value) S1 of time fuel consumption (practical measurement value) A as shown in Figure 4, that measure and setting and setting on this display picture 26.At this moment, in Fig. 4 expression have with the time as transverse axis, time fuel consumption (rise/h) as the chart of the longitudinal axis.In addition, in Fig. 5 the expression have with the time as transverse axis, operation fuel consumption (liter/m
3) as the chart of the longitudinal axis.
Fuel consumption for example can be made of the fuel sensor that the flow fuel that flows on fuel supply channel is detected etc. with detection device 31.Input in the arithmetic unit 33 from the checkout value of this fuel consumption with detection device 31, in this arithmetic unit computing time fuel consumption.In addition, sensor of being detected by the useful load to scraper bowl of workload detection device 32 etc. constitutes.For example, the workload during loading is by the useful load of detection scraper bowls such as monitor camera, by calculating such as (useful load * number of times/time).In addition, the workload during carrying can be obtained by (Weight Loaded * distance) etc.In addition, the workload that is detected by workload detection device 32 inputs in the arithmetic unit 33, at this, the operation fuel consumption is calculated.In addition, when this workload is detected, also can not use sensor, detect the useful load of scraper bowl by worker's naked eyes.
At this, the predefined time fuel consumptions of setting such as time fuel consumption vial reason personnel, for example, in 80 tonnes of hydraulic excavators, carrying out with 80% specified degree in the heavy operation of operation, be set at 65 and (rise/h) degree, carrying out with 65% specified degree in the medium-sized operation of operation, be set at 50 and (rise/h) degree, carrying out with 50% specified degree in the light-duty operation of operation, be set at 40 and (rise/h) degree.In addition, predefined operation fuel consumptions such as the operation fuel consumption vial reason personnel of setting for example, can be set at 40 (liter/m
3) degree.
Therefore, in the building machinery that as above constitutes, calculate time fuel consumption or operation fuel consumption when carrying out operation, compare with the setting value of being set by setting device 35, what show in display picture 26 is poor.At this moment, for the time fuel consumption, available chart is represented as shown in Figure 4.That is, wherein expression have practical measurement value A and goal-setting value S1 (65 liters/h).In this Fig. 4 10 hours the mean value of practical measurement value A be 60 (rise/h).In addition, for the operation fuel consumption, as shown in Figure 5, for example expression has (40 liters/m of practical measurement value B and goal-setting value S2
3).In Fig. 5,10 hours mean value is 50 (liter/m
3), in addition, when in the time fuel consumption, surpassing the goal-setting value, also have, when in the operation fuel consumption, surpassing the goal-setting value, on described display picture 26, show and urge the instruction that improves fuel consumption.The instruction that urgency improves fuel consumption for example is " fuel consumption is many " etc.
Like this, in operation process, the operator that are positioned at operating room 11 know the actual time fuel consumption and the difference of predefined time fuel consumption etc.Thus, poor according to this, operator can make the operation of actual fuel consumption near predefined fuel consumption.When in time fuel consumption etc., surpassing the goal-setting value,, not the operation of excellent in efficiency, can promptly carry out to improving the operation of fuel consumption so operator can grasp the present operation of just carrying out because demonstrations such as " fuel consumption are many " is arranged.In addition, when walking, if reduce engine revolution, speed can be slack-off, but the fuel consumption situation can improve.In addition,, fuel efficiency (travel distance of per 1 liter of fuel) can be improved, the operation of excellent in efficiency can be carried out thus by reducing engine revolution.Therefore, when walking, reduce being operating as of engine revolution and impel the operation that improves fuel consumption.In addition, using working machine 4 to excavate in the operation of native sand, same, when making engine revolution become maximum number of revolutions, though operating speed is fast, power becomes the highest, and fuel consumption is many.To this, if reduce engine revolution, though operating speed and power reduce, fuel consumption diminishes, and can improve fuel consumption efficiency.Therefore, reduce the operation that improves fuel consumption in the urgency of excavating native sand operation that is operating as of engine revolution.And if the angle of swing of working machine is big, then fuel consumption becomes big, so also show the suggestion that angle of swing is diminished sometimes.
In the building machinery that as above constitutes, because can knowing from display picture 26 by vision, operator urge the demonstration that improves fuel consumption in the walking operating process or in the various operation process, so in when walking or when carrying out operation (when for example using the excavation of working machine etc.), can make great efforts to improve the manipulation or the operation of fuel consumption, can realize energy-conservation.And, can constitute detection device and control gear etc. simply, can realize the reduction of cost.In addition, urgency improve the demonstration of fuel consumption etc. can aforesaid mode of execution like that the display picture 26 by the display equipment 22 that in this kind building machinery, loads in the past carry out, the display equipment of the special use different with so existing display equipment 22 also can be set separately, show by this special-purpose display equipment and urge the instruction that improves fuel consumption operation etc.
In addition, as other mode of execution, sound generator (omitting among the figure) can be set in operating room 11, the sound by this sound generator can impel the guidance that improves fuel consumption.At this moment, the sound of this sound generator shows and can carry out separately, also can show with described display device and carry out.If under the situation for the sound demonstration, operator can concentrate one's energy to carry out manipulation operations confirm can to grasp above-mentioned various instruction under the situation of the place ahead state by front window 23 grades, can carry out stable operation etc.But,,, in this case,, then know instruction if show with described display device because there is the situation that is difficult to hear instruction in the noise in operation building site etc. if under the situation for the sound demonstration.Therefore, show and display device demonstration when using together, can notify instruction reliably to operator at sound.
As other mode of execution, in display unit 30, also can form the mode that the opening state that shows above-mentioned instruction and the closed condition that do not show this instruction are switched.That is, for example, under the situation that display device shows, by the button 27 of display equipment 22 being operated can being switched.In addition, even under the situation with the sound demonstration, also can switch by diverter switch is set in sound generator.Like this, if can and not show that the closed condition of instruction switches to the opening state that shows instruction, when not considering to improve fuel consumption etc. under the situation, display unit 30 can be in closed condition, carry out the operation of manipulation operations and working machine so can concentrate in the mode of not carrying out display device demonstration and sound demonstration.In addition, when wanting to urge the operation that improves fuel consumption, if make display unit 30 be in opening state, then can impel the instruction that improves fuel consumption by demonstrations such as display device or sound, operator can make great efforts to carry out manipulation or the operation for improving fuel consumption.In addition, in display unit 30, can carry out in the situation of switching of opening state and closed condition, even the situation that first elapsed time fuel consumption etc. is calculated when opening state, also can with the opening and closing state of display unit 30 irrespectively when the motor of this building machinery moves computing time fuel consumption etc., when display unit 30 is in opening state, impel the demonstration that improves fuel consumption with display device or sound.
Below, second mode of execution of the present invention is described.In following explanation, be that the center describes with difference with first mode of execution, for formation or the function common, represent with same numeral with first mode of execution, omit its explanation.
In the present embodiment, as an example of building machinery hydraulic excavator is described in the same manner with first mode of execution.In the hydraulic excavator of present embodiment, be provided with a plurality of work patterns of the variant elemental operation kind of expression working load.Work patterns such as " heavy mining mode ", " mining mode ", " micromanipulator pattern " are for example arranged in the present embodiment.When carrying out operation, worker oneself can select and the corresponding arbitrary work pattern of job content that carries out at once.The hydraulic excavator of present embodiment is corresponding with selected work pattern to carry out variant control.The summary of each work pattern is as described below, about detailed control sequence, since on the books in No. 2670815 communique of Japan Patent, so please refer to its content.
" heavy mining mode " is the work pattern of digging operation of loading greatly, if represent the acting characteristic of this pattern with engine torque plotted curve and pump output curve diagram, then shown in Fig. 6 (a).That is, engine revolution is according at N
AOn certain substantially mode move, the output of pump (horsepower) is equally at PS
AGo up and move according to certain mode.
" mining mode " is the work pattern that carries out the moderate duty digging operation, if represent the acting characteristic of this pattern with engine torque plotted curve and pump output curve diagram, then shown in Fig. 6 (b).What dotted line was represented is the plotted curve of heavy mining mode.That is, engine revolution is according at N
BOn certain substantially mode move, the output of pump is equally at PS
BGo up and move according to certain mode.
" micromanipulator pattern " is the work pattern that carries out little load, smaller digging operation, if represent the acting characteristic of this pattern with engine torque plotted curve and pump output curve diagram, then shown in Fig. 6 (c).What dotted line was represented is the plotted curve of heavy mining mode.That is, engine revolution is according at N
COn certain substantially mode move, the output of pump is equally at PS
CGo up and move according to certain mode.
From the acting characteristic of above-mentioned each work pattern as can be known, the torque when each work pattern carries out operation and export variant.Correspondingly, fuel consumption is also variant in each work pattern.Therefore, preferably the target fuel consumption also is set at different values in each work pattern.Therefore, in the present embodiment, the goal-setting value (following also abbreviate as sometimes " desired value ") of fuel consumption is set at and the corresponding value of selected work pattern, its practical measurement value with the fuel consumption that records is compared.
The hydraulic excavator of present embodiment comprises control circuit as shown in Figure 7.That is, this control circuit comprises: fuel consumption is measured fuel consumption with detection device 31, is used for fuel consumption computing time; Workload is measured workload with detection device 32, is used for the computational tasks fuel consumption; Arithmetic unit 33, based on fuel consumptive use detection device 31 and workload are calculated time fuel consumption and operation fuel consumption with the measurement result of detection device 32; Display unit 30 is used for showing the practical measurement value of time fuel consumption and operation fuel consumption and the comparing result between each desired value.The structure of these devices 31,32,33,30 is identical with first mode of execution.The control circuit of present embodiment also comprises: input device 40, accept from the selection input of worker's work pattern etc.; Motor control gear 50 is controlled motor and pump; Desired value is determined device 51, according to the information that input device 40 is accepted, determine fuel consumption relatively in the desired value of use; Storage device 52 is stored the desired value of each work pattern etc.; Fuel consumption relatively installs 53, time fuel consumption, operation fuel consumption and the desired value separately of practical measurement compared, and whether be to judge below the desired value to the practical measurement value.
Input device 40 for example is made of the button 27 of display equipment 22 (with reference to figure 1).At this, the plan view of expression display equipment 22 in Fig. 8.Display equipment 22 comprises as the display picture 26 of display unit 30 and a plurality of button 27.The worker uses this work pattern selector button 27A to select work pattern.In addition, input device 40 will be notified to desired value by the work pattern that the worker operates selection and determine device 51.
In the present embodiment, as described later, set each desired value of making time fuel consumption and operation fuel consumption desired value in linkage, itself and practical measurement fuel consumption are compared corresponding to selected work pattern with the selection of work pattern.In addition, also can set the certain desired value that does not rely on work pattern.Whether can select by the pattern interlock/non-interlock selector button 27B that sets in advance at display equipment 22 with the work pattern interlock.In addition, input device 40 will select the advisory of work pattern interlock or non-interlock to determine device 51 to desired value by pattern interlock/non-interlock selector button 27B.
In storage device 52, store the goal-setting value of fuel consumption.For example, in storage device 52, store as shown in Figure 9 form T.In this form T, store the goal-setting value L11～L31 of time fuel consumption, the goal-setting value L12～L32 of operation fuel consumption according to work pattern, and goal-setting value L41, the L42 of mode common.These values can be set arbitrarily by personnel such as job management persons.
Return Fig. 7 again and proceed explanation.Desired value determines that device 51 accepts the notice of input device 40, and fuel consumption is relatively installed 53 indication select target values.For example, desired value determine device 51 from input device 40 by pattern interlock/when non-interlock selector button 27B accepts to select the notice of the non-interlock of work pattern, this context notification is relatively installed 53 to fuel consumption.In addition, when selecting the work pattern interlock by pattern interlock/non-interlock selector button 27B, desired value determines that device 51 will be notified to motor control gear 50 by the work pattern that work pattern selector button 27A selects and fuel consumption relatively installs 53.
Motor control gear 50 carries out the control of engine control and pump when determining that from desired value device 51 is subjected to the notice of work pattern, so that hydraulic excavator moves according to the power corresponding with this work pattern of being notified.
Fuel consumption installs relatively that a kind of in 53 time fuel consumptions of being calculated for arithmetic unit 33 and the operation fuel consumption consumes or the comparison of each practical measurement value and each desired value is carried out in two kinds of consumption.At this, fuel consumption is relatively installed 53 desired values that will be used for comparison and is worked as the selection approach of selecting from storage device 52 according to the notice of determining device 51 from desired value.For example, when receiving that from desired value drive unit 51 the non-interlock of work pattern is notified, select and shared desired value L41, the L42 of acquisition model from storage device 52, its specific consumption desired value that acts as a fuel.In addition, when determining that from desired value device 51 is received the notice of work pattern, select and acquisition and the corresponding time fuel consumption of being notified of work pattern and the goal-setting value of operation fuel consumption from storage device 52, with its specific consumption desired value that acts as a fuel.
In addition, during greater than desired value, fuel comparer 53 is to display unit 30 indications, its comparative result of indicated number in comparative result practical measurement value.The display format of comparative result can have various, for example, can export the information of urging the regulation improve fuel consumption, warn to the worker, also can with first mode of execution in the same manner, as shown in Figure 4 chart is presented in the display unit 30.And, also can with first mode of execution in the same manner, except being presented at display unit 30 external application voice outputs etc., circulate a notice of to the worker with other output unit.
Below, according to flow chart shown in Figure 10, the processing sequence that time fuel consumption and operation fuel consumption compare is described being used for.
Whether at first, the worker operates the pattern interlock/non-interlock selector button 27B of input device 40, select the desired value of fuel consumption is linked with work pattern.If work pattern is determined device 51 and is received the notice of selecting the non-interlock of work pattern from input device 40, then its context notification is relatively installed 53 to fuel consumption, fuel consumption is relatively installed 53 and is selected with reference to the goal-setting value (L41, L42) of the mode common of 52 pairs of time fuel consumptions of storage device and operation fuel consumption.(S11: not, S12).
On the other hand, work pattern is determined device 51 (S11: be) when input device 40 receives that input device 40 is selected the notice of work patterns interlock, further accepts the notice (S13) of the pattern that the work pattern selector button 27A by input device 40 selects.Work pattern determines that device 51 is notified to fuel consumption with the work pattern of selecting and relatively installs 53, and fuel consumption is relatively installed the goal-setting value (S14) of 52 selections of 53 reference storage devices and corresponding time fuel consumption of work pattern and operation fuel consumption.So finish initial setting.
Then, after set finishing in the early stage, with first mode of execution similarly, the fuel consumption in the stipulated time that based on fuel consumptive use detection device 31 is measured, arithmetic unit fuel consumption 33 computing time (S15).In addition, fuel consumption in the stipulated time of based on fuel consumptive use detection device 31 mensuration and workload use detection device 32 by arithmetic unit 33 computational tasks fuel consumptions (S16).
Fuel consumption is relatively installed the practical measurement value of 52 pairs of time fuel consumptions of calculating and operation fuel consumption in step S15 and S16 and each desired value of selecting in step S11 or S14 compares (S17).(S17: be) warned on display unit 30 and urges the demonstration (S18) that improves fuel consumption etc. when in addition, one of them or boths' practical measurement value surpassed desired value.Arbitrary practical measurement value is when desired value is following (S17: deny) all, skips steps S18.
In addition, carry out the processing of step S15 repeatedly, up to the end of job (S19) to step S18.
Thus, set and the corresponding desired value of work pattern in the desired value that can compare in practical measurement value with time fuel consumption and operation fuel consumption.Compare by desired value and practical measurement value, can improve the guidance of fuel consumption the worker to each work pattern.In addition, by only selecting work pattern, but interlock and target setting value therewith.And the worker also can freely select the setting of the desired value of fuel consumption to want to link with work pattern.
