Fig. 1 shows the structural representation according to the monitor of the utility model embodiment.As shown in Figure 1, the monitor according to the utility model embodiment comprises rotary encoder 1, control unit 4, mode selection module 3, high speed counting module 2, alarm unit 7 and telltale 8.
Rotary encoder 1 detects displacement and the output and the cooresponding impulse singla of gig displaced phase of gig, as shown in Figure 1, rotary encoder 1 can be installed on the drive motor 10 of gig, in addition, rotary encoder 1 also can be installed on the reel 13 or gig guide wheel (not shown) of gig.Reel 13 links to each other with drive motor 10 by retarder 11, so that driven by drive motor 10.Between reel 13 and retarder, drg 12 can be set, be used for the rotation of brake drum 13.
High speed counting module 2 is from rotary encoder 1 received pulse signal and calculate the quantity of impulse singla.Control unit 4 utilizes the speed that calculates gig from the quantity of the impulse singla of high speed counting module 2 receptions.Particularly, for example, by input controllers such as diameter with lifting drum 13, for example the pulsimeter of rotary encoder 1 generation is calculated the displacement (position) of gig operation, utilize displacement then and move the used time of described displacement, just can calculate the speed of each position of gig in a stroke.According to the installation site of rotary encoder 1 and the model of gig, for example, the displacement of each pulse representative is in 1 millimeter to 1 centimetre scope.
Mode selection module 3 is switch control unit 4 between mode standard and real-world operation pattern, and wherein under mode standard, control unit 4 is a standard speed with the speed record of the gig that calculates.For example, control unit 4 is switched under the mode standard, allow mine hoist safety move a stroke, be used as the standard speed of mine hoist safety operation under the speed record of control unit 4 with each position of gig in a stroke, the precision height of the standard speed that this calculates than theoretical formula.Certainly, be understandable that gig can move a plurality of strokes, control unit 4 is a standard speed with the speed record in the optimum stroke of gig in a plurality of strokes, thus, also can constantly revise as the standard speed of control benchmark.According to the further embodiment of the utility model, control unit 4 is with the standard speed of each position of form record gig in a stroke of standard speed curve, as shown in Figure 2, certainly, also can be with the form record standard speed of learning data, as shown in Figure 9, Fig. 9 only shows a part of learning data.
Under the real-world operation pattern, control unit 4 compares the gig that calculates in the actual speed in desired location and standard speed corresponding to described desired location, when the difference of actual speed and standard speed surpasses first threshold, for example when actual speed was above standard speed 10% or 15%, control unit 4 sent danger signal so that stop gig.In other words, under the real-world operation pattern, gig operation under the study mode standard monitors, thus make mine hoist safety operation in the real-world operation.
Though having described control unit 4 above is standard speed with the speed record of each position of gig in a stroke under mode standard; be understandable that; the utility model can be taked different recording modes a different position of stroke according to gig; for example; bigger to gig in the speed record data volume of braking section, fully satisfy the requirement of protection precision.In addition, gig can be a standard speed with the speed record that promotes a plurality of pre-positions of loom in a stroke only, for example, the speed that only writes down accelerating sections and braking section is standard speed, thus, when real-world operation, control unit 4 can also provide precision higher standard speed at braking section when total travel provides standard speed.
