Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is further described.
Fig. 1 is the running parameter save set of the working mechanism of the engineering machinery that proposes of the embodiment of the present invention, comprise controller 11 and be arranged on the memory block 12 in controller 11, controller 11 is for the operation of one or more working mechanisms of control engineering machinery, engineering machinery comprises all kinds of crane (truck-mounted cranes, crawler crane, tower crane etc.), mixed mud pump, excavator, rotary drilling rig, continuous wall trench machine etc., the working mechanism of engineering machinery for example comprises engine, lifting mechanism, slew gear, derricking gear, travel mechanism, pumping system, bucket, grab bucket etc.Single controller 11 can only be controlled the operation of Yi Ge working mechanism, also can control the operation of a plurality of working mechanisms simultaneously; For example, for truck-mounted crane, it can arrange two controllers 11, one of them controller 11 only controls for the operation to engine that (now this controller also can be described as ECU, Electronic Control Unit, be electronic control unit), for control the operation of a plurality of working mechanisms such as lifting mechanism, slew gear, derricking gear simultaneously, (now this controller also can be described as PLC to another controller 11, Programmable Logic Controller, i.e. logic controller).Controller 11 is in controlling the process of working mechanism's operation, and memory block 12 is for preserving controlled working mechanism at the running parameter of run duration.Wherein, the maintenance of running parameter Zhi Dui working mechanism, maintenance, assessment etc. play a crucial role and need long-term parameter of preserving, such as working time of working mechanism, historical failure etc.; Working time refers to the work cumulative time of working mechanism, for example, for truck-mounted crane, can be for the work cumulative time of its engine, the walking cumulative time of the work cumulative time of lifting mechanism, travel mechanism, the walking accumulative mileage of vehicle etc.
The quantity of memory block 12 is one or more, and being X(X is to be more than or equal to 1 integer) individual, be respectively the first memory block 12, the second memory block 12 ..., X memory block 12.Each memory block 12 is for preserving Yi Ge working mechanism at a running parameter of run duration, so this X memory block 12 can be used for preserving respectively same working mechanism or different operating mechanism at X running parameter of run duration; This sentences running parameter is that working time of working mechanism is example, when controller 11 is only when controlling the operation of engine, the value of X can be 1, a memory block 12 is namely only set and for preserving the work cumulative time of engine in controller 11; When controller 11 is for simultaneously when for example the operation of lifting mechanism, slew gear, derricking gear Gong Sange working mechanism is controlled, the value of X can be 3, and namely controller 11 is interior arranges three memory blocks 12 and be respectively used to preserve working the cumulative time separately of lifting mechanism, slew gear, derricking gear; These are only that the present invention is not limited to this for example.
In each memory block 12, comprise that at least two is that Y(Y is more than or equal to 2 integer) individual storer 13, be respectively first memory 13, second memory 13 ..., Y storer 13, the value of Y depends on the size of the running parameter of required preservation, the working time that this running parameter of sentencing preservation is working mechanism is example, be kept to a corresponding memory block 12 working time when interior, first will be kept at the working time on first memory 13, when if on first memory 13, the data of storage reach preset value and have been filled with, no longer first memory 13 is carried out to storage operation, and then will be kept at the working time while being also filled with on second memory 13 and by second memory 13, in like manner no longer second memory 13 is carried out to storage operation, and then again storage operation is switched on the 3rd storer 13, the like, utilize Y storer 13 jointly to store the working time parameter of working mechanism, the data summation of Y storer 13 is the work cumulative time of working mechanism, that is to say, the present invention shares the work cumulative time of working mechanism to be stored on a plurality of storeies 13, 13 parts of preserving the work cumulative time of each storer, not only can reduce the number of times of writing with a brush dipped in Chinese ink that single memory 13 is carried out, can also reduce the interval holding time.The work cumulative time that the needs of for example take are preserved was example as 1,000 hundred ten thousand seconds, if only adopt a storer and interval holding time, was ten minutes (600 seconds), needed this storer to write with a brush dipped in Chinese ink 1.67 hundred ten thousand times; If adopting ten storeies and interval holding time is two minutes (120 seconds), each storer only need be write with a brush dipped in Chinese ink 0.83 hundred ten thousand time; Therefore, also reduced the interval holding time (being decreased to two minutes from ten minutes) having reduced when storer being write with a brush dipped in Chinese ink to number of times (be reduced to from 1.67 hundred ten thousand times 0.83 hundred ten thousand time).
In the present embodiment, the structure of each storer 13 is identical with memory capacity, Fig. 2 is that the structure of each storer 13 forms schematic diagram, in each storer 13, there is n continuous storage unit, be respectively Memory1, Memory2 ..., Memory n, each storage unit is for example a byte, and each byte is 8bit.Take the working time of preserving working mechanism is example, and the working time data T that 13 of each storeies can be stored is:
T=(M1+M2*256+……+Mn*(256)
n)
Below illustrate the storing mode of the work cumulative time of certain working mechanism, suppose that working mechanism on average works 10 hours every day, be >=50 years tenure of use, the work cumulative time is designed to preserve once (requiring Tn≤10 second) second at interval of Tn,, in normal mission life, the working time of storer preserves number of times Life and is:
365 days * 10 hours * 60 minutes * 60 seconds/Tn=657000000/Tn time=657/Tn of Life=50 * 1,000,000 times
Tn≤10 second as requested, Life >=65.7 is 1,000,000 times
If each memory block 12 each storer 13(is below that first memory 13 is to Y storer 13) permission be respectively Life_1 serviceable life, Life_2, Life_y, and it is all 1,000 ten thousand times, the value that only need to get y >=7(and be Y is 7), with 13 of 7 storeies, can reach the requirement in serviceable life of preserving 50 year working time, in 7 storeies 13, respectively store 1,000 ten thousand times, it is 1,000 ten thousand * 10 seconds=10,000 ten thousand seconds=27778 hours that each storer 13 allows the time maximal value of storage, the accumulative total of 7 storeies 13 can holding time=single memory * storage time storer number=27778 hour * 7=194446 hour.
At present in engineering machinery, conventionally can reach 1,000 ten thousand times left and right the serviceable life of the storer 13 in controller 11 used, the present invention is by for example, storing at the running parameter (working the cumulative time) of each memory block 12 a plurality of storer 13Dui of interior employing working mechanism, the data of storing on the previous storer 13 in memory block 12 reach preset value Tmax and represent to be filled with, 13 pairs of these running parameters of storer that the next one in selected this memory block 12 of controller 11 is not filled with are preserved operation, the run duration of this running parameter Gai working mechanism carries out cumulative statistics and also according to the interval holding time of setting, is kept on the selected storer not being filled with 13, wherein this preset value Tmax equal each storer 13 allow write with a brush dipped in Chinese ink number of times (take be example above, be 1,000 ten thousand times) (take is example above with the interval holding time of setting, for being less than or equal to 10 seconds) product, be Tmax=10 1,000,000 * 10 seconds=10,000 ten thousand seconds.Like this, in each memory block 12, there is sufficient storage space for Memory Extension, and can control the number of times of writing with a brush dipped in Chinese ink to single memory 13, also can shorten the interval holding time, solve long problem of interval holding time simultaneously.
Fig. 3 is the principle of work process flow diagram of above-mentioned running parameter save set, and incorporated by reference to Fig. 3, the method for utilizing above-mentioned running parameter save set to preserve the running parameter of the working mechanism of engineering machinery that the embodiment of the present invention proposes, comprises the steps:
When the running parameter of Jiang working mechanism is saved to the memory block 12 of controller 11 interior correspondences, read the data of the first memory 13 in this memory block 12;
Whether the data that judgement is read are more than or equal to preset value;
If when the data that read are more than or equal to preset value, read the data of next storer 13 and compare with preset value;
When the data that read from next storer 13 are less than preset value, the memory location that the storer 13 of determining current reading out data is running parameter; And

When having certain controller to be the new controller being replaced, by the controller 11a(or the 11b that do not change) storage data in upper each memory block 12 back up to respectively in each memory block 12 on new controller;
When the running parameter of Dui working mechanism carries out cumulative statistics and preserves, selected one of them controller 11a(or 11b) as the controller of preserving this running parameter, and another controller 11b(or 11a) controller used as data backup;
The running parameter of Jiang working mechanism is saved to selected controller 11a(or 11b) in during corresponding memory block 12, read the data of the first memory 13 in this memory block 12;
Whether the data that judgement is read are more than or equal to preset value;
If when the data that read are more than or equal to preset value, read the data of next storer 13 and compare with preset value;
When the data that read from next storer 13 are less than preset value, the memory location that the storer 13 of determining current reading out data is running parameter;
The running parameter of working mechanism is carried out to cumulative statistics to be also kept on memory location according to the interval holding time of setting; And
The data of running parameter are being kept to selected controller 11a(or 11b) when upper or afterwards, further data backup was saved to another controller 11b(or 11a) on.
Particularly, in above-mentioned steps, when have the data of each memory block 12 on certain controller be zero or data hour, can judge that this controller is as the new controller being just replaced.By by the controller 11a(or the 11b that do not change) storage data in upper each memory block 12 back up to respectively in each memory block 12 on new controller, like this, after a controller is replaced therein, controller 11a(or the 11b that can after recover installing, automatically original save data never be changed) in back up on new controller, can not cause the loss of original save data.
