Embodiment
The invention discloses a kind of crane and drive manipulation analytical approach, to realize the object of the Presentation Function expanding crane
In order to make those skilled in the art understand technical scheme provided by the invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Refer to Fig. 1, Fig. 1 is the schematic flow sheet that manipulation analytical approach driven by a kind of crane.
Manipulation analytical approach driven by this crane, comprises the following steps:
The run signal of step S1, reception crane, knows the operating condition residing for crane.
Particularly, when described run signal is service brake signal, the operating condition residing for the crane known is brake operating operating mode;
When described run signal is accelerator pedal signal, the operating condition residing for the crane known is throttle operation operating mode;
When described run signal is the angular signal of a Shaft angle sensor, the operating condition residing for the crane known is cornering operation operating mode.
Step S2, gather operational factor corresponding to current crane operating condition.Wherein, described operating condition comprises the operation of brake operating, throttle operation and corner, and described operational factor comprises retarded velocity, rotating speed and the speed of a motor vehicle.
In addition, also comprise before this step and judge whether crane is in transport condition, judge that the method whether crane is in transport condition has a lot, such as, by judging that whether the crane speed of a motor vehicle is 0 just can judge whether crane is in transport condition, when the speed of a motor vehicle is 0, then crane is not in transport condition, when the speed of a motor vehicle is greater than 0, crane is in transport condition.
When described operating condition is brake operating operating mode, the operational factor obtaining current crane operating condition corresponding is: receive braking speed of a motor vehicle when braking occurs, and the detection speed of a motor vehicle after braking enforcement first Preset Time, the retarded velocity of crane according to formulae discovery;
Above-mentioned formula is
wherein, a is retarded velocity, v
2for detecting the speed of a motor vehicle, v
1for the braking speed of a motor vehicle, Δ t is the first Preset Time.
When described operating condition is throttle operation operating mode, the operational factor obtaining current crane operating condition corresponding is: gather the rotating speed that described throttle operation operating mode is corresponding.
When described operating condition is cornering operation operating mode, the operational factor obtaining current crane operating condition corresponding is: gather the speed of a motor vehicle that described cornering operation operating mode is corresponding.
Step S3, judge whether described operational factor is greater than default operational factor, then enters step S1 if not; If then enter step S4.
Wherein, in brake operating operating mode, operational factor is retarded velocity, presets operational factor for presetting retarded velocity.Judge what rear vehicle mainly occurs by detecting braking for brake operating improper display retarded velocity carried out judging.According to " GB7258-2007 motor vehicle safe and technical specification ", full Terrain Cranes braking deceleration should be greater than 5m/s
2; When vehicle deceleration is greater than 3m/s
2time, think and implement to be greater than 60% braking, the main negative effect of high strength braking is the wearing and tearing, the increase oil consumption that increase detent.First Preset Time and default retarded velocity can be determined according to the experience of operator or national standard in embodiments of the present invention, such as, are more than or equal to 3m/s according to the retarded velocity in above-mentioned formulae discovery 3s
2time, then think that this brake operating is high strength brake operating.Particularly, whether the retarded velocity in brake operating operating mode is greater than default retarded velocity, if then, enters step S4; Otherwise enter step S1.
In throttle operation operating mode, judge that the throttle operation size whether reasonably criterion can be opened according to throttle judges, if the size that throttle is opened is not in economic zone, think that throttle operation is unreasonable; Can also judge according to the rotating speed of engine, when the rotating speed of engine is not in economic zone, be then considered as throttle operation unreasonable, in embodiments of the present invention preferably, operational factor is rotating speed, and default operational factor is preset rotation speed.The size of preset rotation speed is determined according to the experience of operating personnel or national standard.Particularly, whether the rotating speed in throttle operation operating mode is greater than preset rotation speed, if then, enters step S4, otherwise enters step S1.
In cornering operation operating mode, dangerous display is that standard carries out showing with the pass of travel speed and steering angle.When travel speed is larger, if now steering angle is also comparatively large, then vehicle is just tumbled than being easier to, and steering angle is with a Shaft angle for Rule of judgment, and crane chassis has many axles usually, and can realize different turning to pattern.A so-called Shaft angle refers to the steering angle of the most front axle of crane chassis, chassis is obtained by the angular transducer be arranged on axletree.Now, operational factor is the speed of a motor vehicle, and default operational factor is preset vehicle speed.The preset vehicle speed that under different corner, correspondence one is maximum, when receiving one week corner size, calls the maximum preset speed of a motor vehicle that this corner is corresponding.Particularly, whether the speed of a motor vehicle in cornering operation operating mode is greater than preset vehicle speed, if then enter step S4, otherwise enters step S1.
Step S4, current operating condition to be marked.Comprehend different for different operating condition mark.
Because operating condition comprises the operation of brake operating, throttle operation and corner, under so different operating conditions, its decision method is as follows.
When described operating condition is brake operating operating mode, system marks this braking according to corresponding mark formula.In mark formula, mark is proportional with braking severity, and it is fiercer to brake.That is, the retarded velocity calculated is compared with default retarded velocity, and larger so brake operating is fiercer.In the present invention, mark is main adopts deduction of points to mark, and brakes the more of fiercer deduction of points mark.
Above-mentioned crane is driven in manipulation analytical approach, and when described operating condition is throttle operation operating mode, described mark is treated to: the maximum mark got in the second Preset Time is this mark.Described second Preset Time does not do and limits and can demarcate by Stringency as requested.In the present invention, mark is main adopts deduction of points to mark.
Above-mentioned crane is driven in manipulation display packing, and when described operating condition is corner operation, described mark is treated to: getting maximum mark in the 3rd Preset Time is this mark.Described 3rd Preset Time does not do and limits and can demarcate by Stringency as requested.In the present invention, mark is main adopts deduction of points to mark.
Step S5, issue idsplay order according to described mark.
Every mark comprises brake operating mark, throttle operation mark and corner operational label, is total driving information after every mark adds up summation respectively after being multiplied by corresponding scale-up factor summation.Display shows according to this idsplay order.
There is provided the problem of crane driving information to be technical matters, after adopting a set of analytical approach in accordance with the laws of nature, send idsplay order in concrete the present invention, to show the information after this analysis, thus extend crane Presentation Function.And although problem those skilled in the art of crane Presentation Function expansion can set, the size of those skilled in the art according to display and the discrimination of human eye, set according to certain ratio, the Presentation Function of display is limited.The application realizes under the condition of limited display capabilities, show the more function of crane, and can not be addressed this problem by artificial set and display quantity.And under the prerequisite not adopting technological means, simple removes set and display device, be cannot show current crane to drive the ability of manipulation display.Therefore, in the application expanded scope Presentation Function be technical matters.
The collection of the operational factor in above-mentioned each operating process in each operating condition relates to the collection of data, and the gatherer process of data applies the technological means meeting the natural law, and its implementation process and human factor have nothing to do, and thus have employed technological means.
Judge whether described operational factor is greater than default operational factor, if then mark current operating condition.Whether operational factor is greater than default operational factor, have employed the technological means meeting the natural law equally, has nothing to do, thus have employed technological means equally with human factor.
Because operating condition irrational in the driving procedure of operator marks by the method, then issue idsplay order according to mark.Therefore, make crane can show the information of the current manipulation situation of operator, thus extend the Presentation Function of display.Thus reach the effect meeting the natural law, and human factor has nothing to do.
In sum, owing to solving technical matters in the application and have employed the technological means followed the course of nature, and the technique effect meeting the natural law is obtained.
According to idsplay order, net result is shown.Wherein, display result can be different in different situations, such as, can distinguish in embodiments of the present invention according to the difference of distance travelled number, travels little mileage correspondence first and preset mileage, be referred to as single and travel, and needs to carry out single traveling and drive analysis; Travel the second default mileage that large mileage is corresponding, be referred to as comprehensive traveling, need to carry out driving comprehensive analysis.As shown in Figure 4, the result that single traveling shows after analyzing comprises this distance travelled, this travels score, this traveling used time and monitoring and appraisal; The data of as shown in Figure 5, and comprehensively driving display comprise total score and analyse score, Braking Analysis score, hazard analysis score, throttle analysis score, chassis Operations Analyst score and comprehensive evaluation and suggestion.
Above-mentioned crane is driven in manipulation analytical approach, as shown in Figure 2, when travelling in little mileage, the run signal of described reception crane, also comprises step S1 ' before knowing the operating condition residing for crane: record this distance travelled number travelled and this running time;
Described issue idsplay order according to described mark before also comprise step S4 ': know the distance travelled of crane be greater than first preset mileage.Travel for single and analyze, the value of the first default mileage is less than normal, considers employing 20 kilometers in this embodiment of the present invention, and as the first default mileage that single travels, can also be other values certainly, the present invention make and clearly limiting.
When analyzing for comprehensive driving, as shown in Figure 3, above-mentioned crane is driven in manipulation display packing, travel larger fare register, step S1 is also comprised before the operational factor that described collection current crane operating condition is corresponding ": before initialization, second presets the display data in mileage, and records this distance travelled number travelled and this running time;
Described issue idsplay order according to described mark before also comprise step S4 ": know that the distance travelled of crane is accumulative and reach second and preset mileage.
Above-mentioned crane is driven in manipulation display packing, described operating condition also comprises chassis operation, second presets the comprehensive analysis method in mileage (getting 200 kilometers in present specification), except above-mentioned three display standards, namely the size of the rationality of car brakeing, accelerator open degree, Ackermann steer angle corner whether rationally outside, increase chassis misoperation display.The logic that must specify according to control program due to crane chassis suspension operational order, supporting leg sequence of operation, differential operation order completes.Misoperation refers to that operator (driver) is when operating these actions, has the operation (long-term misoperation can cause damage to vehicle) of running counter to control program logic.In driving and operation control display system, trace routine, by the sequencing met certain operation condition, judges whether to run counter to steering logic, the cumulative mark of operating mistake, finally adds up after being multiplied by scale-up factor and counts total mark.
When described operating condition is chassis operation operating mode, the chassis of crane is the part supporting heavy-duty machine lift heavy mechanism, carries crane transfer and the effect supported.For general-utility car, crane chassis is driven except moving operation, also needs chassis to operate, and chassis operation comprises vehicle hanging lifting, supporting leg action, the actions such as differential mechanism switching and multi-axle steering control.Operational factor is sequence of operation, and default operational factor is predetermined registration operation order.
In comprehensive driving display, list the mark value of four display indexs, frequency provide comprehensive display score and suggestion respectively.In the present invention, above-mentioned four display standards form display system jointly, but their proportion shared is in the display system determined according to the scale-up factor of correspondence, for when focusing on energy-conservation state in crane running process, the coefficient shared by throttle operation is comparatively large, and other are several relatively little.For the crane focusing on driving safety, the scale-up factor of corner operation occupies relatively larger.Four kinds of display standards complement each other, and can ensure the objective rationality showing result.
Because operating condition irrational in the driving procedure of operator marks by the method, meter also finally shows.The manipulation of operator to oneself can be made to have one to be familiar with more intuitively, and then operator can be helped to overcome bad driving habits.Travel display for single to show with comprehensive manipulation the in fixing kilometer, in display, have the display of particular content.Drive after display terminates comprehensive, will display this drive or the score of manipulation process, and point out that the tag entry when time operation is maximum advise with display, help operator to correct bad driving habits, the serviceable life of raising vehicle component.
