It is described in detail with new.
Embodiment 1：
As shown in Figure 1,3, a kind of greasing device with fuzzy discrimination function, including a greasing device body, in greasing device sheet
The inside of body is provided with central control unit, and the feeder ear of central control unit is connected with power supply unit battery, and in center, control is single
Mu balanced circuit is provided between member and power supply unit battery, the signal acquisition terminal of central control unit passes through signal transacting acquisition module
It is connected with the sensor for detecting lubricating utensil, the pump motor drive module for opening and closing greasing device controls with center
The control terminal of unit is connected, and sensor includes temperature sensor, vibrating sensor, and sensor gathers to be believed by the state of lubricating utensil
Number, signal data is sent to central control unit by signal transacting acquisition module, central control unit is to receiving
Signal data is handled, and is converted into frequency signal, amplitude signal, frequency spectrum or the envelope signal that can be used for analysis, and carry out
Effectively analysis, realize that the fuzzy lubrication of equipment controls using the fuzzy diagnosis and FUZZY ALGORITHMS FOR CONTROL technology of automatic field,
According to equipment operational shock cycle, Oscillation Amplitude, effective window judgement is carried out, by vibration period, Oscillation Amplitude with greasing frequency
It is secondary to establish an effective fuzzy control model, realize equipment do not work do not lubricate, low frequency operation low frequency lubrication, high-frequency work it is normal
State lubrication, the superpower lubrication of hyperfrequency work, the effect of the high-strength lubrication of high frequency high-amplitude, avoid equipment downtime from causing to lead for a period of time
The deficient lubrication operation of equipment when causing lubricant significantly aggregation and overloading.Pass through the equipment running frequency and vibration width of data sampling
The size of value can set up a FPT mathematical modeling.
As shown in figures 4-9：The fuzzy lubrication control FPT models emphasis is based on equipment operation working frequency, amplitude, operation
Time, three parameters were configured.Purpose realizes the fuzzy control tracking and processing of the lubrication control of equipment, realizes equipment
Benign lubrication.Realize equipment do not work do not lubricate, low frequency operation low frequency lubrication, high-frequency work normality lubrication, hyperfrequency work
Superpower lubrication, the effect of the high-strength lubrication of high frequency high-amplitude, avoid equipment downtime from causing to cause lubricant significantly to gather for a period of time
The deficient lubrication operation of equipment when collection and overload.By the normal operation oscillating curve of lubricating utensil as shown in Fig. 4-Fig. 9, according to
Actual experiment data, the vibration data that vibrating sensor is collected, by windowing process, obtain the reality in certain time period
Effective operational shock waveform, and by the digital filtering software algorithm of processor processor, obtain the set band number to be analyzed
According to frequency spectrum data, know actual running frequency, actual vibration amplitude, set a coordinate threshold value (F_A, P_A, T_A),

Can still normality be used to lubricate with reference to figure 9, if locating BC sections in fig.9；If being in AB sections, need to combine and shake
The variation tendency of dynamic acceleration fat is adjusted as one sees fit, if the vibration acceleration tested can increase the unit interval in increase
Lubrication equivalent adjust, if vibration acceleration is constant or temperature changing trend is descending along Fig. 9 BC sections, this explanation is smooth
Properly, lubricate and measure by normality；If the follow-up variation tendency of vibration acceleration measured value of equipment is reduces, but temperature
Variation tendency is increase, then illustrates smooth excessive, it is necessary to reduce lubrication equivalent or increase lubrication interval.
In the FPT models of reality, in addition in fuzzy discrimination amounts of lubrication and adjustment dosage, except becoming with reference to amplitude
Change with outside temperature change, also have two other key parameter index：Fig. 6 be collection signal discrete analysis-frequency spectrum data surely frequency
Side frequency situation near point, Fig. 7 are the acquisition of signal peak, carpet value.Put into practice according to the equipment development of reality, in sliding apparatus
Lubricating area, consider the side frequency frequency spectrum near 0.5 frequency multiplication emphatically, if side frequency is abundant and discreteness is strong, namely peak value is more, and greatly
In set setting value Fmax, then need to increase amounts of lubrication on the basis of original lubrication；If side frequency signal is relatively flat, i.e.,
Blanket value is more, and is less than set setting value Fmax, illustrates that equipment operates steadily, lubrication state is good.According to the equipment development of reality
Practice, in the lubrication of rolling equipment, in the frequency conversion of the tangible odd number frequency of focus, judgement of the basis for estimation with reference to above-mentioned East China
Foundation, analyzed by actual experiment and the onsite application of equipment, but be not dominant at 0.5 times of frequency, be actually
