Detailed description of the invention
Referring to accompanying drawing, one embodiment is described in detail.
Fig. 1 represents integrally-built system construction drawing, in FIG, 1 represents lift car, and 2 represent the electrical motor driving elevator, 3 represent the counterbalanced weight be arranged on the position relative with lift car, and lift car 1 and counterbalanced weight 3 are linked by pulley 4 and hoist cable 5.In addition, electrical motor 2 is provided with coder 6, the impulse singla of the coder 6 produced according to the rotation along with electrical motor 2, detects position and the speed of elevator, the traveling of carrying out elevator thus controls.
Governor sheave 7 and lift car 1 rotate linkedly, and governor coder 8 is installed on governor sheave 7 in the mode of dual.Governor coder 8 produces impulse singla along with the rotation of governor sheave 7, and it can be used as the speed detection signal of lift car and position detection signal to be input in safety governor 14.In addition, be provided with in the hoist trunk of elevator and whether be positioned at undermost terminal floor detector switch (downside) 9 for detecting lift car 1 and detect the terminal floor detector switch (upside) 10 whether lift car 1 is positioned at the superiors.The position detector 11 of the position detecting lift car 1 is installed at the car upper section of lift car 1, has the shield 12 of position probing accordingly in each storey setting of hoist trunk with position detector 11.By making shield 12 cover position detector 11, can judge which floor lift car 1 has arrived thus.Position detector 11 for safety system, so preferably input to safety governor 14 in the mode of dual.
Control setup 13 uses the pulse of the coder 6 be arranged on electrical motor 2 to come position and the speed of detection and control elevator, safety governor 14 detects speed and the position of lift car 1 according to the impulse singla of the governor coder 8 be arranged on governor sheave 7, judge whether exceed the speed limit relative to the position of lift car 1, and when being judged as there occurs hypervelocity, make lift car 1 carry out emergent stopping etc.
Fig. 2 is the block diagram of the sequential operation process of the time dependent change of related detection governor sheave groove.
Run from orlop because floor height measures, and terminate in the superiors, so via inputoutput buffer (I/O) 15, the signal of terminal floor detector switch (downside) 9 and terminal floor detector switch (upside) 10 is input to safety governor 14.Governor coder 8 has carried out dual by the first system and second system, and respective impulse singla is input to safety governor 14.In addition, detect lift car 1 by position detector 11 and whether have passed the shield 12 being arranged on each floor, and its signal is sent into safety governor 14 via inputoutput buffer (I/O) 15.
Microcomputer (MPU) 16 is main portions of safety governor 14, and it carrys out the impulse singla of the governor coder 8 of accumulative the first system and second system by position detection part 17, to generate position data.In addition, the floor height data of each floor are generated according to the position data at positive rise (ON edge) place during end of position detector 11 by shield 12.Lift car 1 rises from orlop, and when terminal floor detector switch (upside) 10 conducting, be judged as arriving the superiors, floor height data store 18 stores the floor height data of each floor generated.
When governor sheave 7 there occurs time dependent change and wearing and tearing, data exception judging part 19 is judged as there occurs exception according to the floor height data of each stored floor, from inputoutput buffer (I/O) 15 by control conductor 20 and via the inputoutput buffer (I/O) 21 being arranged on control setup 13 inside, send to the microcomputer (MPU) 22 in control setup 13 and represent that governor sheave groove there occurs the information of time dependent change.Simultaneously, diameter of pulley data point reuse portion 23 in safety governor 14 is revised the diameter of governor sheave temporarily, maintain the speed of lift car 1 and the precision of position, can not decline with the judgement precision and reliability of guaranteeing hypervelocity, thus play the performance of safety governor 14.
Fig. 3 represent from be completed time floor height measure run play governor sheave groove there occurs time dependent change time abnormality detection flow process.At orlop, under the state in terminal floor detector switch (downside) conducting, lift car 1 starts towards rising direction running (upwards travelling) (S1).After this, while using the positive rise place of position detector 11 during travelling when the end of each floor by shield 12, the position data that obtained by the governor coder 8 of the first system and second system stores as the positive rise detection position of shield, makes lift car 1 continue upwards to travel (S2).When the difference of the position data of the first system and second system has exceeded specified value, be judged as there occurs exception.In the superiors, under the state in terminal floor detector switch (upside) conducting, lift car 1 is stopped (S3).
When the positive rise detection position of shield 11 does not store resume, when the floor height data of each detected floor being completed as elevator, the primary data of (namely initial condition) carries out storing and preserving (S4).Now, make lift car 1 rise to the superiors from orlop, generate the floor height data of each floor as primary data.Thus, can not obscure with the floor height data recorded when the superiors drop to orlop, can reliability be improved.
After completion, regular implementation level high assay runs, and the floor height data of each floor and primary data when being completed is compared (S5).
When the departure of floor height data has exceeded the numerical value preset, be detected as and occurred wearing and tearing abnormal (S7).The numerical value preset can be obtained by the departure being converted into floor height data from the wearing and tearing tolerance limit value of governor sheave diameter.
When being judged as there occurs wearing and tearing exception, export the anomaly detection signal (S8) requiring to change governor sheave.Because the replacing of governor sheave needs the regular hour, so afterwards by calculating, temporary transient is less data by the diameter of pulley data correction be set in the program of safety governor 14, reduce the position data of the lift car 1 of the unit-pulse signal of governor coder 8, impulse singla is made to become many relative to floor height data, thus, carry out judgement by position data safety governor 14 the same as before and guarantee its function (S9).The correction of these diameter of pulley data is preferably not only carried out when being judged as there occurs wearing and tearing and being abnormal, but also carries out when the departure of floor height data has exceeded specified value.
In addition, the floor height data of each floor and primary data are not compared, and using the spacing (interval) at positive rise place during end by shield 12 of position detector 11 as position data (shield spacing), and the primary data of each floor gap is it can be used as to store.Further, the same with floor height data, regularly carry out floor height and measure operation, when the departure of shield spacing is beyond the numerical value preset, be judged as there occurs wearing and tearing abnormal.That is, except the departure of floor height data, also consider the departure of shield spacing and compare with primary data, reliability can be improved further thus.In addition, in the above description, be illustrated for the situation that regular implementation level high assay runs, but during the common lifting that also can be arranged in lift car 1 runs, the comparison of the departure of shield spacing is carried out at each floor, multiple shield spacing and primary data are compared, now, does not need to carry out special diagnosis and run the diagnosis just can carrying out high reliability to the time dependent change of governor pulley groove.
