Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.
As shown in Figure 1, at monitoring guide pin bushing of the present invention or/and the method for guide pillar temperature and the device embodiment in, its monitoring guide pin bushing or/and the method for guide pillar temperature comprise the steps:
Step S11 carries out respectively analog to digital conversion by each input data, obtain digital signal: in this step, by obtaining the data that mean its current temperature value on the temperature sensor be arranged on guide pin bushing or guide pillar, and these data are carried out to analog to digital conversion, obtain numerical signal corresponding to these data.In general, temperature sensor its resistance at different temperature changes, and makes the curtage of its output change, according to this variation, if know the temperature characterisitic of this temperature sensor, just can obtain the current temperature value of this temperature sensor environment of living in.In the present embodiment, different data values collected, the conversion respectively that the temperature sensor of installing on a plurality of guide pin bushings or guide pillar is exported due to temperature variation, obtain corresponding digital signal value.In other embodiments, if the data of the temperature sensor of installing on above-mentioned guide pin bushing or guide pillar output itself are exactly digital signal or what collect due to other reasons is digital signal, above-mentioned analog-to-digital step is omissible, but the step of image data still exists.
Step S12 inputs above-mentioned digital signal respectively, and selects one of them processing: in the present embodiment, above-mentioned digital signal is inputted respectively, is also parallel the input, between each signal, does not have mutually relation simultaneously.After these data are received, be stored in buffer memory, wait processing; In this step, take out one of them data, these data can be selected in this step, also can in other steps, select.
Step S13 contrasts a numerical value in this digital signal and preset value: in the present embodiment, the data value (this data value is by the temperature sensor output of guide pin bushing or guide pillar and through converting) of selecting in above-mentioned steps is compared one by one with one group of preset value of storage in advance, compare a preset value at every turn.In this step, exactly the preset value of the above-mentioned data value of choosing and selection is carried out to subtraction.In the present embodiment, above-mentioned preset value be to be arranged on above-mentioned guide pin bushing or guide pillar on temperature sensor be relevant, different temperature sensors, above-mentioned preset value may be just different.For example, a kind of temperature sensor, it is under fixing voltage, and when 50 spend, output voltage values is 5V, and when 51 spend, output voltage values is 5.1V, will comprise 5 and 5.1 in above-mentioned preset value; Between above-mentioned preset value, be to have certain ，Qi interval, interval not necessarily uniform, but these temperature intervals that are worth this kind of represented temperature sensor are uniformly, for example, 1 degree etc.Simultaneously, numerical value when this preset value has just selected some may appear at guide pillar or guide pin bushing work for example, negative temperature can not occur when above-mentioned guide pillar or guide pin bushing work, so, just there is no the numerical value that negative temperature value is corresponding in above-mentioned preset value.When the data bit 5V of guide pin bushing or guide pillar input, and do not know the temperature value of its representative, but, by finding its immediate preset value, search again the driving signal that this preset value is corresponding, when this driving signal outputs to display unit, its numerical value shown is exactly this kind of temperature sensor its ambient temperature value of living in when this data value of output.
Is the absolute value of step S14 difference less than the second setting value? in this step, judge whether the absolute value of the difference of above-mentioned subtraction is less than the second setting value, as be less than, jump to step S18 and carry out; Otherwise, carry out next step.Wherein, above-mentioned the second setting value is also in advance to set and store, if the absolute value of difference is less than this value, shows that the gap of inputting between data and preset value is enough little.

Step S16 takes out the next numerical value in preset value: in this step, take out the another one in above-mentioned preset value, and return to step S13, again repeat above-mentioned steps S13-S15, the preset value data of taking-up and the data of input are compared again.In the present embodiment, the above-mentioned data that are selected normally with preceding step in the data relatively crossed adjacent, and be greater than or less than the next data of these data.
Does this supplied with digital signal of step S17 relatively complete? in this step, the data that judge whether all guide pin bushings that will once collect according to above-mentioned steps or guide pillar input relatively complete, as all relatively completed, return to step S11, start data acquisition next time and process, if no, return to step S12, select another input data to start comparison.In the present embodiment, in this step, judging whether the input data that once gather are finished dealing with, is that one of every processing, just locate these data clearly because the data that collect all are stored in an appointed area; If can not sense data in appointed area, mean that the data of this collection out complete.
Step S18 selects this preset value for approaching most preset value: in this step, and owing to having judged that in step S14 preset value is enough little with the difference that participates in input data values relatively, therefore in this step, selects this preset value for approaching most preset value.
Does step S19 approach preset value most and is greater than the first setting value? in this step, judge whether the above-mentioned preset value that approaches most is greater than the first setting value, as be more than or equal to the first setting value, carry out next step; Otherwise, jump to step S21.
Step S20 exports control signal, start alarm: in this step, be more than or equal to the first setting value owing to approaching most preset value, the guide pillar of these data of expression input or the temperature of guide pin bushing are higher, have surpassed the temperature value allowed, so, the output control signal, make the alarm performance element start working, send sound and light alarm, remind operating personnel to note.After the output control signal, execution step S21.
Step S21 takes out this and approaches the driving signal that preset value is corresponding most, and with send to display unit together with the port numbers of supplied with digital signal: in this step, search the corresponding driving signal of immediate preset value, it is corresponding that these drive signal to be suitable for preset value, is to store in advance equally.These drive signal to be actually the driving signal that the represented temperature of each preset value shows this temperature value on display unit.Send to real unit, the guide pin bushing that makes operating personnel can be clear that each input port connects or the temperature of guide pillar by these signals together with the port numbers of inputting data.It is worth mentioning that, in the present embodiment, above-mentioned display unit is LCD MODULE, and the driving signal that above-mentioned driving signal is exactly Liquid Crystal Module.Above-mentioned port numbers is presented at the different sections of above-mentioned Liquid Crystal Module from driving signal, makes the operator be easy to identification, simultaneously, also makes and drives signal not need again to convert.After executing this step, jump to step S17.In addition, whether the output of above-mentioned alarm control signal, with this step, has nothing to do, no matter whether alarm control signal is exported or no warning, this step all can be carried out.
