Embodiment
For making the object, technical solutions and advantages of the present invention clearly, 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 the embodiment of the present invention proposes, the memory block 12 comprising controller 11 and be arranged 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 crane, crawler crane, tower crane etc.), mixed mud pump, excavator, rotary drilling rig, continuous wall trench machine etc., the working mechanism of engineering machinery such as comprises engine, lifting mechanism, slew gear, derricking gear, travel mechanism, pumping system, bucket, grab bucket etc.Single controller 11 only can control the operation of a working mechanism, also can control the operation of multiple working mechanism simultaneously; Such as truck-mounted crane, it can arrange two controllers 11, only for controlling the operation of engine, (now this controller also can be described as ECU to one of them controller 11, ElectronicControlUnit, i.e. electronic control unit), another controller 11 is for controlling the operation (now this controller also can be described as PLC, ProgrammableLogicController, i.e. logic controller) of multiple working mechanisms such as lifting mechanism, slew gear, derricking gear simultaneously.Controller 11 is in the process controlling working mechanism's operation, and memory block 12 is for preserving the running parameter of controlled working mechanism at run duration.Wherein, running parameter refers to that the maintenance, maintenance, assessment etc. to working mechanism plays a crucial role and the parameter of needs preservation for a long time, the working time, historical failure etc. of such as working mechanism; Working time refers to work cumulative time of working mechanism, such as, for truck-mounted crane, can be the work cumulative time of its engine, the work cumulative time of lifting mechanism, the walking cumulative time of travel mechanism, the walking accumulative mileage etc. of vehicle.
The quantity of memory block 12 is one or more, be X(X be more than or equal to 1 integer) individual, be respectively the first memory block 12, memory block 12, second ..., X memory block 12.Each memory block 12 is for preserving the running parameter of a working mechanism at run duration, and therefore this X memory block 12 can be used for preserving respectively same working mechanism or different operating mechanism X the running parameter at run duration; This sentences running parameter be working time of working mechanism is example, when controller 11 is only for controlling the operation of engine, the value of X can be 1, namely only arranges a memory block 12 in controller 11 and work cumulative time for preserving engine; When controller 11 is for controlling the operation of such as lifting mechanism, slew gear, derricking gear three working mechanisms simultaneously totally, the value of X can be 3, namely three memory blocks 12 are set in controller 11 and be respectively used to preserve lifting mechanism, slew gear, derricking gear the respective work cumulative time; These are only citing, the present invention is not limited to this.
Comprise in each memory block 12 at least two namely Y(Y be more than or equal to 2 integer) individual storer 13, be respectively first memory 13, second memory 13 ..., Y storer 13, Y value depend on the size of the required running parameter preserved, this running parameter sentencing preservation is the working time of working mechanism is example, when the working time being kept in a corresponding memory block 12, first will be kept at the working time on first memory 13, if the data that first memory 13 stores reach preset value when being namely filled with, no longer storage operation is carried out to first memory 13, and when then will to be kept at the working time on second memory 13 and second memory 13 is also filled with, in like manner no longer storage operation is carried out to second memory 13, and then again storage operation is switched on the 3rd storer 13, the like, Y storer 13 is utilized 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, the work cumulative time of working mechanism shares and is stored on multiple storer 13 by the present invention, the part of work cumulative time preserved by each storer 13, not only can reduce single memory 13 is carried out write with a brush dipped in Chinese ink number of times, the interval holding time can also be reduced.Such as to need the work cumulative time of preserving to be 1,000 hundred ten thousand seconds, if only adopt a storer and the interval holding time is ten minutes (namely 600 seconds), then need to write with a brush dipped in Chinese ink 1.67 hundred ten thousand times to this storer; According to ten storeies and the interval holding time be two minutes (namely 120 seconds), then each storer only need write with a brush dipped in Chinese ink 0.83 hundred ten thousand time; Therefore, reduce storer 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) while also reduce the interval holding time (being decreased to two minutes from ten minutes).
In the present embodiment, the structure of each storer 13 is identical with memory capacity, Fig. 2 is the structure composition schematic diagram of each storer 13, there is in each storer 13 n continuous print storage unit, be respectively Memory1, Memory2 ..., Memoryn, each storage unit is such as a byte, and each byte is 8bit.To preserve the working time of working mechanism, the operating time data T that each storer 13 can store is:
T=(M1+M2*256+……+Mn*(256)
n)
Below illustrate the storing mode of the work cumulative time of certain working mechanism, suppose working mechanism's average operation every day 10 hours, tenure of use is >=50 years, the work cumulative time is designed to preserve once (requiring Tn≤10 second) second at interval of Tn, then in normal working life, the working time of storer preserves number of times Life and is:
Life=50 * 365 days * 10 hours * 60 minutes * 60 seconds/Tn=657000000/Tn time=657/Tn 1,000,000 times
Tn≤10 second as requested, then Life >=65.7 1,000,000 times
If each storer 13(below each memory block 12 and first memory 13 are to Y storer 13) permission be respectively Life_1 serviceable life, Life_2, Life_y, and be all 1,000 ten thousand times, the value of getting y >=7(and Y is then only needed to be 7), the requirement in serviceable life of 50 year working time of preservation can be reached with 7 storeies 13, each storage 1,000 ten thousand times in 7 storeies 13, each storer 13 allows the time maximal value stored to be 1,000 ten thousand * 10 seconds=10,000 ten thousand seconds=27778 hours, 7 storeies 13 accumulative can holding time=single memory * storage time storer number=27778 hour * 7=194446 hour.
In current engineering machinery, the serviceable life of the storer 13 in controller 11 used can reach about 1,000 ten thousand times usually, the present invention stores by adopting the running parameter (such as working the cumulative time) of multiple storer 13 pairs of working mechanisms in each memory block 12, then represent be filled with when the data that the previous storer 13 in memory block 12 stores reach preset value Tmax, controller 11 is selected the storer 13 that the next one in this memory block 12 is not filled with and is carried out preservation operation to this running parameter, this running parameter carries out cumulative statistics at the run duration of this working mechanism and is kept on the selected storer 13 be not filled with according to the interval holding time set, wherein this preset value Tmax equal each storer 13 allow write with a brush dipped in Chinese ink number of times (for above, be 1,000 ten thousand times) and setting the interval holding time (for above, for being less than or equal to 10 seconds) product, i.e. Tmax=10 1,000,000 * 10 seconds=10,000 ten thousand seconds.Like this, have sufficient storage space in each memory block 12 for Memory Extension, and can control to write with a brush dipped in Chinese ink number of times to single memory 13, while also can shorten the interval holding time, the problem that the solution interval holding time is long.

When this running parameter of working mechanism being saved to memory block (12) corresponding in this selected controller (11a or 11b), read the data of the first memory (13) in this memory block (12);
Judge whether the data read are more than or equal to preset value;
If when the data read are more than or equal to preset value, then read the data of next storer (13) and compare with preset value;
When the data read from this next storer (13) are less than preset value, then determine the memory location that the storer (13) of current read data is this running parameter;
Cumulative statistics is carried out to this running parameter of working mechanism and is kept on this memory location according to the interval holding time set; And
When the data of this running parameter being kept at this selected controller (11a or 11b) and being upper or afterwards, further data backup is saved on another controller (11b or 11a).
