Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, be cage guide installation quality of the present invention detection system embodiment schematic diagram, its can be used for the installation quality to cage guide carry out quick, accurately detect.Cage guide installation quality detection system in the present embodiment includes running control unit 11, current sampling unit 12, drag evaluation unit 13 and resistance output unit 14, above-mentioned operation control unit 11, current sampling unit 12, drag evaluation unit 13 and resistance output unit 14 can be located at a host computer, and this host computer realizes cage guide quality testing by being connected with converter.Certainly, run control unit 11, current sampling unit 12, drag evaluation unit 13 and resistance output unit 14 and also can be integrated into converter, thus detection can be directly realized by by converter.
Run control unit 11 to be used for making transducer drive lift car (namely transducer drive traction machine drives cage operation) omnidistance round operation at a predetermined velocity once (travel at the uniform speed).This operation control unit 11 is when starting guide rails assembling quality testing, by whether converter automatic decision lift car is in bottom, if lift car is not at bottom, then makes transducer drive elevator cage operation to bottom；After lift car is in bottom, then transducer drive lift car is made to come and go operation once (in actual applications, running control unit 11 also can make transducer drive car come and go operation from top layer to bottom once) from bottom to top layer whole process.
Especially, for improving the accuracy of detection, run control unit 11 and make transducer drive lift car come and go operation once with inspection speed whole process.
Current sampling unit 12 is at the uniform velocity coming and going at a predetermined velocity in running at lift car, and sampling car is at the torque current (namely converter exports the torque current of motor) of each hoistway position place converter.The frequency of current sampling unit 12 sampling is more high, and the result of guide rails assembling quality testing is more accurate.
Such as: when lift car is up, the current data of current sampling unit 12 sampling is:

Especially, this resistance output unit 14 exports the guide rail resistance at each hoistway position place with the form of guide rail resistance distribution curve；This guide rail resistance distribution curve with hoistway position be abscissa, guide rail resistance for vertical coordinate, or this guide rail resistance diagram with guide rail resistance be abscissa, hoistway position is for vertical coordinate.By guide rail resistance distribution curve, it is simple to user more intuitively understands guide rails assembling quality.Certainly, in actual applications, resistance output unit 14 exports the guide rail resistance of each hoistway position also by other forms.
In addition, above-mentioned cage guide installation quality detection system may also include fault cues unit, for at guide rail resistance along with hoistway position is in output guide rail perpendicularity fault cues when being gradually increased or be gradually reduced, and/or when fluctuation occurs in guide rail resistance there is the prompting of projection or abrasion in output guide rail in corresponding hoistway position.By fault cues unit, automatically guide rails assembling quality can be pointed out, facilitate operation.
As in figure 2 it is shown, be the schematic flow sheet of cage guide installation quality detection method embodiment of the present invention.The method includes the following steps performed by the host computer (or converter itself) being connected with converter:
Step S21: make omnidistance the coming and going of transducer drive lift car (inspection speed of such as elevator) at a predetermined velocity run once.
In this step, can first pass through whether converter automatic decision lift car is in bottom, if lift car is not at bottom, then make transducer drive elevator cage operation to bottom；After lift car is in bottom, then transducer drive lift car is made to run once from bottom to omnidistance the coming and going of top layer (or from top to bottom).
Step S22: at the uniform velocity coming and going at a predetermined velocity in running at lift car, sampling car is at the torque current of each hoistway position place converter.The frequency of current sample is more high, and the result of guide rails assembling quality testing is more accurate.
Step S23: calculate the guide rail resistance at this hoistway position place according to the car upstream sampling electric current at identical hoistway position place and descending sample rate current.
This step can calculate the guide rail resistance at corresponding hoistway position place by formula calculated below:
Wherein iUpThe torque current of converter, i when going upward to corresponding hoistway position place for carDescendingThe torque current of converter, i when coming downwards to corresponding hoistway position place for carSpecifiedRated torque current for motor.
Step S24: export the guide rail resistance at each hoistway position place.Thus user can confirm the installation quality of cage guide and the type of guide rails assembling defect, position etc. according to the guide rail resistance at each hoistway position place of above-mentioned output.Such as guide rail Resistance Value is excessive to be reflected guide rail and leads tension between boots；As in a certain hoistway position, guide rail Resistance Value occurs that fluctuation then can reflect that guide rail exists protruding or abrasion in this hoistway position；If guide rail Resistance Value is in the trend being gradually increased or being gradually reduced, then it represents that slide rail verticality is problematic.
Especially, in this step, guide rail resistance distribution curve can be drawn according to the guide rail resistance at each hoistway position place, this guide rail resistance distribution curve with hoistway position be abscissa, guide rail resistance for vertical coordinate, or this guide rail resistance diagram with guide rail resistance be abscissa, hoistway position is for vertical coordinate.
