The specific embodiment
The invention will be further described below in conjunction with specific embodiments and the drawings, but should not limit protection scope of the present invention with this.
Fig. 1 shows the structured flowchart of the floating crane operation intelligent monitor system of present embodiment, mainly comprise: parameter acquisition module 11, signal processing module 12, long-haul telemetry module 13, video collector 14, analog input interface 15, digital input interface 16 comprise display module, annunciator, first nonvolatile memory, the second nonvolatile memory (not shown in figure 1) in addition.
Wherein, parameter acquisition module 11 is used for gathering the duty parameter of floating crane, comprises and gathers the residing environmental parameters of floating crane and the operational factor of self, the i.e. correlation parameter of the parameter of device external and equipment self inside.As example, parameter acquisition module 11 in the present embodiment comprises the weight sensor 111 for detection of lifting weight, angular transducer 112 for detection of the crane arm angle, height sensor 113 for detection of the lifting height, amplitude sensor 114 for detection of the lifting amplitude, for detection of the air velocity transducer 115 of current wind speed, and amplitude limit switch 116, slewing limit switch 117, height limit switch 118 and hoisting moment limit switch 119.Need to prove, it will be appreciated by those skilled in the art that the sensor that is used for gathering duty parameter that can also comprise other suitable types in the parameter acquisition module 11.
In the present embodiment, the signal of weight sensor 111, angular transducer 112, height sensor 113, amplitude sensor 114, air velocity transducer 115 outputs is analog signal, inputs in the signal processing module 12 by analog input interface 15; The signal of amplitude limit switch 116, slewing limit switch 117, height limit switch 118,119 outputs of hoisting moment limit switch is digital signal, transfers in the signal processing module 12 by digital input interface 16.
And if no abnormal duty parameter, i.e. equipment operation is normal, then temporary duty parameter is sampled, sampling frequency is default sampling frequency, and in duty parameter unloading to the first nonvolatile memory of the gained of will sampling.
Fig. 2 shows the detailed structure view of signal processing module 12, comprise temporary storage 123 and the signal processor that links to each other with temporary storage 123, signal processor in the present embodiment specifically comprises arm processor 121 and the dsp processor 122 that cooperatively interacts and use, in addition, Fig. 2 also shows first nonvolatile memory 17 and second nonvolatile memory 18 that links to each other with signal processing module 12.
Wherein, temporary storage 123 can be memory devices such as SDRAM, DRAM, according to the principle of first-in first-out duty parameter is kept in.Because the capacity of temporary storage 123 is limited, thereby after the storage space that is used for temporary duty parameter is taken, follow-up duty parameter will override previous data, be stored in the temporary storage 123 according to the principle of first-in first-out.
Still with reference to figure 1, the intelligent monitor system of present embodiment can also comprise the display module (not shown) that links to each other with signal processing module 12, is used for temporary duty parameter is shown in real time, makes the user can see various duty parameters intuitively.Displaying contents in the display module can be the data of duty parameter itself, also can be after treatment various curves, figure etc., so that the user checks.
In addition, signal processing module 12 also is connected with the annunciator (not shown), sends alerting signal when duty parameter unusual (being that the current working parameter exceeds default parameter area), and the user is pointed out.
Continuation is with reference to figure 1, and signal processing module 12 also is connected with long-haul telemetry module 13, and temporary duty parameter is sent to long-range monitor terminal.Can communicate by modes such as ethernet, fieldbus and cordless communication networks between long-haul telemetry module 13 and the monitor terminal, make long-range user also can check the operation conditions that equipment is current.
In addition, the floating crane operation intelligent monitor system of present embodiment can also comprise supply unit (main power source and emergency source of electrical power etc.), wherein can guarantee when mains power failure still can normal operation for emergency source of electrical power, continues the duty parameter of recording unit operation.
Fig. 3 shows the workflow of the floating crane operation intelligent monitor system of present embodiment, and in step S31, overall counting variable n is set to 0; In step S32, it is 200ms that collection period is set afterwards, and to be signal processing module receive cycle of duty parameter from the parameter acquisition module to this collection period, namely is set at per second and receives 5 duty parameters; In step S33, duty parameter is gathered afterwards, the duty parameter of at every turn gathering gained is called a record; In step S34, the duty parameter of gathering is stored in the temporary storage, in step S35, overall counting variable n is calculated afterwards, namely whenever keep in a record, overall counting variable n just adds 1; In step S36, current duty parameter and default parameter area are compared, judge whether to be accident (perhaps being called unusual), if the comparison result indication is unusual, execution in step S37 then, in temporary storage, this record is labeled as accident, and with the duty parameter in the current record and before in duty parameter unloading to the first nonvolatile memory in the record in the Preset Time section, in the present embodiment, this Preset Time section is 20s, in other words, detect and 100 previous records can be saved in first nonvolatile memory in the lump after unusual, transfer back to step S33 after the unloading; If the judged result among the step S36 is for denying, execution in step S38 then, judge whether overall counting variable n has been accumulated to 3000, if, then execution in step S39 is re-set as 0 with overall counting variable n, transfers back to step S33, if the judged result among the step S38 then transfers back among the step S33 for not.
In the example shown in Figure 3, the every 200ms of signal processing module gathers the record that receives a duty parameter, preserve 3000 records at most, thereby the equipment of can keeping at most moves 10 minutes with interior duty parameter, if note abnormalities then will be before this whole records in the 20s all in unloading to the first nonvolatile memory, if it is no abnormal, then the duty parameter in the temporary storage is sampled, for example sampling frequency can be to extract 1 record in per 300 records, and in record unloading to the first nonvolatile memory that will extract, therefore, can consult in first nonvolatile memory after the user, whole duty parameters of equipment in the 20s before the accident that not only can restore takes place, the part duty parameter the when equipment that also can restore normally moves.
In the present embodiment, the record format of the duty parameter of preserving in the temporary storage is as follows:
If a certain record is marked as the accident doubtful point, then the form of the accident doubtful point data from temporary storage unloading to the first nonvolatile memory is different slightly, specific as follows:
Need to prove that given concrete numeral only is example in Fig. 3 and the description thereof, the frequency, Preset Time section and the default sampling frequency that receive floor data can be adjusted according to the actual requirements, should not be construed as the restriction to the application.
Though the present invention with preferred embodiment openly as above; but it is not to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
