Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, a machine room 2 is provided in the upper part of the hoistway 1. In the machine room 2, a hoisting machine 3 is provided. The hoisting machine 3 includes a drive sheave 4, a hoisting machine motor 5 that rotates the driving sheave 4, and a hoisting machine brake 6 that brakes the rotation of the driving sheave 4.

  An electromagnetic brake is used as the hoisting machine brake 6. The electromagnetic brake includes a brake shoe that contacts and separates from a brake wheel (brake drum or brake disc) 7 that rotates integrally with the drive sheave 4, a brake spring that presses the brake shoe against the brake wheel 7, and a brake shoe against the brake spring. And an electromagnetic magnet for pulling the wheel away from the brake wheel 7.

  The hoisting machine 3 is provided with a rotation detector 8 that generates a signal corresponding to the rotation of the drive sheave 4. For example, an encoder or a resolver is used as the rotation detector 8.

  A baffle wheel 9 is provided in the vicinity of the drive sheave 4. A suspension body 10 is wound around the drive sheave 4 and the deflecting wheel 9. As the suspension body 10, a plurality of ropes or a plurality of belts are used.

  A car 11 is connected to the first end of the suspension body 10. A counterweight 12 is connected to the second end of the suspension body 10. The car 11 and the counterweight 12 are suspended in the hoistway 1 by the suspension body 10 and are moved up and down in the hoistway 1 by the driving force of the hoisting machine 3. The rotation of the drive sheave 4 is transmitted to the suspension body 10 by the frictional force between the drive sheave 4 and the suspension body 10.

  In the hoistway 1, a pair of car guide rails (not shown) for guiding the raising and lowering of the car 11 and a pair of counterweight guide rails (not shown) for guiding the raising and lowering of the counterweight 12 are installed. Has been.

  An emergency stop device 13 that holds the car guide rails and stops the car 11 in an emergency manner is mounted on the lower part of the car 11. A connecting portion of the suspension body 10 to the car 11 is provided with a scale device 14 that generates a signal corresponding to the loaded weight in the car 11.

  A speed governor 15 is installed in the upper part of the hoistway 1. The governor 15 is provided with a governor sheave 16 and a rope catch (not shown). A loop-shaped governor rope 17 is wound around the governor sheave 16.

  The governor rope 17 is connected to the operating lever of the safety device 13. The governor rope 17 is wound around a tension wheel 18 installed at the lower part of the hoistway 1. When the car 11 travels, the governor rope 17 circulates and the governor sheave 16 rotates at a rotational speed corresponding to the traveling speed of the car 11.

  The governor 15 is set with a first overspeed level that is higher than the rated speed and a second overspeed level that is higher than the first overspeed level. When the traveling speed of the car 11 reaches the first overspeed level, the governor 15 cuts off the energization to the hoisting machine motor 5 and suddenly stops the car 11 by the hoisting machine brake 6. When the traveling speed of the car 11 reaches the second overspeed level, the speed governor 15 grips the speed governor rope 17 by the rope catch, stops the speed governor rope 17, and sets the emergency stop device 13. Operate.

  At locations corresponding to a plurality of landings on the hoistway 1, detected plates 19 a are respectively installed. As shown in FIG. 2, the car 11 is equipped with a detected plate detector 19b for detecting the detected plate 19a. A position sensor 19 that detects that the car 11 is at a detection position in the hoistway 1 includes a detected plate 19a and a detected plate detector 19b. In the first embodiment, the position sensor 19 detects that the car 11 is located at the landing position. However, the detected plate 19a can be installed at any position in the hoistway 1 for the purpose of detecting that the car 11 is at a detection position other than the landing position.

  The elevator control device 31 controls the operation of the car 11 by controlling the operation of the hoisting machine 3. Energization of the hoisting machine motor 5 and energization of the hoisting machine brake 6 are controlled by an elevator control device 31. When the car 11 is stopped, the elevator control device 31 operates the hoisting machine brake 6 to keep the car 11 stationary.

  The elevator control device 31 is connected to a slip state determination device 22 that determines a slip state between the drive sheave 4 and the suspension body 10. A slip detection device 21 is connected to the slip state determination device 22.

  The slip detection device 21 detects the slip amount between the drive sheave 4 and the suspension body 10 based on the signal from the rotation detector 8 and the signal from the position sensor 19.

  Specifically, the slip detection device 21 obtains the feed amount of the suspension body 10 when there is no slip from the rotation amount of the drive sheave 4 detected by the rotation detector 8. Further, the slip detection device 21 is based on the feed amount of the suspension body 10 and a signal from the detected plate detector 19b (timing signal generated when the car 11 passes the position of the detected plate 19a). A deviation amount between the amount of the suspended body 10 sent while the car 11 passes between the floors in the hoistway 1 and the distance between the floors stored in advance is detected as a slippage amount when traveling between the floors.

  The slip state determination device 22 is based on the slip amount information detected by the slip detection device 21, the driving force information of the hoisting machine motor 5, and the rotation information from the rotation detector 8. Distinguish between global slip and local slip occurring between 10.

  Specifically, the slipping state determination device 22 has a behavior in which when one of the speed detected by the rotation detector 8 and the driving force detected by the hoisting machine motor 5 increases, the other decreases. Detect the presence or absence. Further, the slipping state determination device 22 performs normal and normal slipping caused by a decrease in the traction capability between the drive sheave 4 and the suspension body 10 based on the amount of slippage between floors and the presence or absence of the above behavior. It is determined which one of the minute slips generated in the entire region in the traction state occurs.

  Further, the slipping state determination device 22 sends information related to the determination result of the slipping state to the elevator control device 31. The elevator control device 31 stores the information received from the slip state determination device 22 and uses it for controlling the elevator device. That is, the elevator control device 31 stops the operation of the car 11 when it is determined that the slip is abnormal due to a decrease in traction capability or the like.

  For example, when the slip amount reaches the first set value, the elevator control device 31 determines that a large slip has occurred and causes the car 11 to perform an emergency stop. Further, even when the slip amount does not reach the first set value, the traction ability is reached when the second set value lower than the first set value is reached and local slip occurs. The car 11 is moved to the nearest floor or a designated floor, and the operation of the car 11 is stopped.

  Further, the elevator control device 31, the slip detection device 21, and the slip state determination device 22 each have independent microcomputers, thereby realizing independent arithmetic processing that is not affected by each other.

  Here, the slip detection process performed by the slip detection device 21 will be described in detail. First, in the slip detection process, it is necessary to retain arrangement interval information of the detection plate 19a.

  FIG. 3 shows a flow of processing for storing the arrangement interval information of the detection plate 19a. In this process, the car 11 is first moved to the reference floor (usually the lowest floor) (STEP 1). Thereafter, the car 11 starts moving to the destination floor (usually the top floor) (STEP 2). During this movement, the signals from the rotation detector 8 are integrated, and the integrated value is stored as the distance information between the floors every time it passes through the detected plate 19a, and the integrated value is reset (STEP 3). Finally, when the movement to the destination floor is completed, the process is terminated.

  This processing flow is preferably performed immediately after installation of the elevator apparatus. That is, immediately after the elevator apparatus is installed, the traction state is healthy and no slip occurs, so the rotation amount of the drive sheave 4 (advance amount due to rotation of the outer periphery of the drive sheave 4) is regarded as the feed amount of the suspension body 10. Therefore, the integrated value between the floors of the signal from the rotation detector 8 can be handled as the distance between the floors.

  Further, when it is determined by the slip state determination device 22 described below that there is no abnormal slip, a process of updating the stored information may be performed.

  Next, the slip detection process will be described in detail with reference to FIG. In this process, as in FIG. 3, the car 11 is first moved to the reference floor (usually the lowest floor) (STEP 4). Thereafter, movement of the car 11 to the destination floor (usually the top floor) is started (STEP 5). During this movement, the signals from the rotation detector 8 are integrated, and the integrated value is stored as the amount of rotation of the drive sheave 4 when passing through the floor every time it passes through the detected plate 19a, and the integrated value is reset. (STEP 6-1, 2).

  Further, the difference between the stored rotation amount of the drive sheave 4 and the inter-story distance information is output as a slip amount to the slip state determination device 22 (STEP 6-3). Finally, when the movement to the destination floor is completed, the process is terminated.

  Next, in order to describe the determination process of the slip state determination device 22, a plurality of slip states that are objects of slip determination are illustrated in FIGS. Each figure shows the time change of the slip amount between the drive sheave 4 and the suspension body 10.

  FIG. 5 shows a small slip that occurs in the whole area in a normal state, and although the size changes somewhat depending on the loading state of the car 11 and the like, a high slip does not occur in the local time. On the other hand, FIG. 6 shows a local large slip that occurs in a local abnormal state, and when this progresses, it leads to a continuous large slip as shown in FIG.

  Here, the relationship with the slip amount detected by the slip detection device 21 will be described. This corresponds to the slip amount in which the painted portion in each figure obtained by integrating the slips in the figure with time is detected. As is clear from these figures, when a continuous and large slip occurs, the slip amount is significantly different from the other two examples, and the distinction is easy. However, there is no difference (or small) in the amount of slip between the case where a small slip occurs in the whole area in the normal state and the case where a large and large slip occurs in the local abnormal state. Cannot be distinguished.

  On the other hand, FIG. 8 is a graph showing the change over time of the rotational speed of the drive sheave 4 and the driving force of the hoisting machine motor 5 when the entire region shown in FIG. 6 is a graph showing temporal changes in the rotational speed of the drive sheave 4 and the driving force of the hoisting machine motor 5 when a large local slip shown in FIG. 6 occurs.

  By using such fluctuation information of the rotational speed of the drive sheave 4 and the driving force of the hoisting motor 5, the above-described two states can be separated. Specifically, when local slip occurs, as shown in FIG. 9, a phenomenon occurs in which the driving speed of the hoist motor 5 decreases at the same time as the rotational speed of the drive sheave 4 increases.

  This is because, when slipping occurs, the frictional force between the suspension body 10 and the drive sheave 4 decreases, and the rotational speed increases due to the driving force applied until just before the frictional force decreases. In a typical elevator, the control that follows the command speed is performed by the elevator control device 31, and thus the driving force is reduced by control so that the speed does not deviate from the command value.

  Therefore, attention is paid to a value obtained by multiplying the rotational speed and the driving force. FIG. 10 is a graph showing the change over time of the value of the rotational speed × the driving force in FIG. 8, and FIG. 11 is a graph showing the change over time of the value of the rotational speed × the driving force in FIG. As shown in FIG. 10, when a small slip occurs over the entire area, the value of rotational speed × driving force is substantially constant within a normal fluctuation range. On the other hand, as shown in FIG. 11, when local and large slip occurs, the value of the rotational speed × driving force decreases at the timing when the slip occurs locally, and from the normal fluctuation range. Come off.

  In this way, by multiplying the rotational speed and the driving force, a value that greatly deviates from the fluctuation range of normal travel where no local slip occurs. And by capturing this feature point, it is possible to more reliably isolate and detect the abnormality. That is, a normal fluctuation range of the amount obtained by multiplying the rotation speed and the driving force is determined in advance, and it is detected that the product of the rotation speed and the driving force during traveling between the floors exceeds the normal fluctuation range. By doing so, it is possible to easily detect the occurrence of local slip with high accuracy.

  It should be noted that the occurrence of local slip may be detected by separately determining the rotational speed and the driving force without performing the calculation of multiplying the rotational speed and the driving force.

  Specifically, as shown in FIG. 12, first, an allowable minimum deviation a1 from the normal driving force when traveling between floors and an allowable maximum deviation b1 of the rotational speed from the normal traveling pattern are determined. Next, when an event in which the deviation of the driving force falls below the allowable minimum deviation a1 and an event in which the deviation of the rotational speed exceeds the allowable maximum deviation b1 occur simultaneously, it is determined that local slip has occurred.

  Further, as shown in FIG. 13, a permissible maximum deviation b2 that can change the rotational speed is determined in accordance with the minimum deviation a2 from the normal driving force when the car 11 travels between floors, and the change in the rotational speed is determined. When the maximum value exceeds the allowable maximum deviation b2, it can also be determined that local slip has occurred.

  Here, as a method of determining b2, if the relationship is set such that b2 increases as a2 decreases and b2 decreases as a2 increases, the increase in the amount of rotation is small but local. When the driving force is reduced due to the slip, and when the amount of rotation is increased due to the local slip, the local slip can be accurately detected.

  For example, if a2 and b2 have an inversely proportional relationship, it can be determined based on the same standard as that determined by the product of the rotational speed and the driving force. As a specific state of determination, in FIG. 12, since the maximum deviation of the rotational speed exceeds the reference b2, it can be determined that a slip has occurred locally.

  Further, contrary to this example, the maximum deviation of the speed is specified first, the allowable minimum deviation of the driving force is determined based on this, and the local deviation is determined based on whether the speed exceeds these allowable values. It may be determined that slipping has occurred.

  Next, FIG. 14 shows a flow of specific slip state determination processing by the slip state determination device 22. Here, in response to the start of movement to the destination floor, the process proceeds to the slip state determination process. In the slip state determination processing, slip amount information from the slip detection device 21 is received, and the received slip amount is compared with a first reference amount of a predetermined slip amount (STEPs 7-1 and 7-2). ).

  If the slip amount is larger than the first reference amount, the first abnormal state is output and the process wait state is returned (STEP 7-3). On the other hand, when the slip amount is smaller than the first reference amount, the received slip amount is compared with a second reference amount of the predetermined slip amount (first reference amount> second reference amount). The process proceeds (STEP 7-4).

  When the slip amount is larger than the second reference amount, an evaluation is further performed as to whether there is any abnormality in the slip behavior (STEP 7-5). The specific evaluation method is as described above.

  If it is determined that there is an abnormality in the sliding behavior, the second abnormal state is output and the process waits back (STEP 7-6). On the other hand, if the slip amount is smaller than the reference amount in STEP 7-4, and if it is determined in STEP 7-5 that there is no abnormality in the slip behavior, the process shifts to the process waiting state.

  Here, the significance of the first abnormal state and the second abnormal state varies depending on the setting of the first and second reference amounts serving as determination thresholds. For example, the first reference amount is a slip amount generated in a traction state where each floor cannot be safely stopped during service. When the slip amount is larger than the first reference amount, safety is ensured by the elevator control device 31 stopping the car 11 at the nearest floor or immediately stopping the service.

  Further, the second reference amount is set to the maximum value of the slip amount that changes due to fluctuations in the loaded weight or the like in a normal state. When the slip amount is equal to or smaller than the first reference amount and larger than the second reference amount, the state information of the elevator apparatus is transmitted to the outside. As a result, an operation that leads to an early state improvement can be considered.

  As a specific transmission device for transmitting the state information, for example, an announcement by voice to the inside or outside of the car 11, display by an image or a lamp in the car 11, and electronic communication with a user's mobile phone can be considered.

  Moreover, you may communicate the progress information which a local slip increases by a communication means or a mobile telephone etc. between an elevator control apparatus and a maintenance worker or a maintenance company. In this case, by performing maintenance before reaching the state where the operation of the elevator apparatus must be stopped, the elevator apparatus can be continuously operated, and the user is not inconvenienced by the operation stop.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described. In the second embodiment, in the slip behavior determination (processing step 7-5 in FIG. 14) in the slip state determination device 22 in the first embodiment, the slip is quantitatively calculated, so that a more accurate slip determination is performed. Realize.

  The slip state determination device 22 of the second embodiment includes slip amount information detected by the slip detection device 21, drive force information of the hoisting motor 5, rotation information from the rotation detector 8, the drive sheave 4 and Based on the information on the inertial mass of the device driven in conjunction therewith, the information on the inertial mass of the suspension 10 and the device operating in conjunction therewith, and the information on the unbalanced weight acting on the drive sheave 4, the drive sheave 4 distinguishes between total slip and local slip that occur between 4 and the suspension 10. Other configurations and operations are the same as those in the first embodiment.

  Equation 1 is an equation of motion when the elevator apparatus is driven via the frictional force between the drive sheave 4 and the suspension body 10.

  In Equation 1, J is the inertia mass of the drive sheave 4 and the device that is driven in conjunction with it, and includes the inertia mass of the rotor of the hoist motor 5 in addition to the drive sheave 4. J ′ is the inertial mass of the suspension body 10 and the device operating in conjunction with the suspension body 10, and the cables (feeding cable) suspended from the suspension body 9, the cage 11 and the counterweight 12 as well as the deflector 9 and the cage 11. And inertial mass such as balancing lines).

  T is a driving force output by the hoisting machine motor 5. F is a frictional force acting between the drive sheave 4 and the suspension body 10. L is an unbalanced weight acting on the drive sheave 4 and is a differential force between the tension of the suspension body 10 on the car 11 side and the tension of the suspension body 10 on the counterweight 12 side when the car 11 is stopped.

  Here, the tension of the suspension body 10 on the side of the car 11 includes the weight of the suspension body 10 from the drive sheave 4 to the car 11 and the suspension of the car 11 in addition to the weight of the car 11 and the loaded weight in the car 11. The weight of the cables used will be affected. Similarly, the tension of the suspension body 10 on the counterweight 12 side is also suspended from the weight of the suspension body 10 from the drive sheave 4 to the counterweight 12 and the counterweight 12 in addition to the weight of the counterweight 12. The weight of cables is affected.

  W is the rotational speed of the drive sheave 4, and V is the feed speed of the suspension body 10. A symbol with a dot on W indicates a time derivative of W, and a symbol with a dot on V indicates a time derivative of V.

  Next, when the slip speed is defined by a ratio δ (slip ratio) with respect to the rotational speed of the drive sheave 4, Equation 2 is obtained.

  Thereby, when Expression 1 is converted into Expression, the relational expression shown in Expression 3 is obtained.

  This equation 3 shows the relationship among the inertia masses J and J ′, the rotational speed W of the drive sheave 4, the driving force T of the hoisting motor 5, the unbalance weight L, and the slip rate δ as a differential equation. In the slip detection device 21 according to the second embodiment, the slip ratio is calculated based on Equation 3.

  In calculating the slip ratio, it is necessary to determine values other than δ in the equation. Of each value, J and J ′ are inertial masses, and therefore can be calculated according to the system configuration. Since W is the rotational speed of the drive sheave 4, it can be calculated based on the signal from the rotation detector 8. Furthermore, since T is the driving force output from the hoisting machine motor 5, it can be calculated by converting the driving current of the hoisting machine motor 5.

  Furthermore, since the unbalance weight L varies depending on the load weight in the car 11, it can be calculated based on a signal from the scale device 14.

  FIG. 15 is a block diagram showing a method for deriving the slip ratio based on Equation 3. FIG. 15 shows a procedure for calculating the slip ratio δ by inputting the relational expression 1 + J / J ′ of the driving force T, the unbalance weight L, and the inertial mass of the hoisting machine motor 5.

  In the figure, in the triangular block, the input value is multiplied with the coefficient in the block and output. The 1 / S block represents an integrator that integrates and outputs an input signal. Further, at the joining point of the two paths, each signal to be joined is subjected to addition / subtraction processing. “+” Is shown next to the input signal line, and “−” is shown next to the input signal line.

  Furthermore, the slip ratio δ is signal-branched immediately before output, and a regression path that uses the branched signal as an input to the previous procedure is provided. The input through this regression path cannot be used because the value is not determined before the output value δ is calculated.

  Therefore, in the calculation at the time of mounting, the processing of the entire block diagram is periodically performed, and the slip ratio δ calculated in the previous cycle is used as an input signal passing through the regression path. At that time, since the slip rate δ changes from moment to moment, an error occurs between the slip rate calculated in the previous cycle and the slip rate at the time of calculation, but the output error is reduced by shortening the processing cycle. Can be small.

  As described above, the slip state determination device 22 performs the arithmetic processing derived from the above-described equation of motion of the elevator device, that is, information on the unbalanced weight acting on the drive sheave 4 and the signal from the rotation detector 8. Information on the rotational amount of the drive sheave 4 detected based on the above, information on the driving force generated by the hoisting machine 3, information on the inertia mass of the drive sheave 4 and the device driven in conjunction therewith, and suspension The slip ratio δ between the drive sheave 4 and the suspension body 10 can be accurately estimated based on the information about the inertial mass of the device 10 and the device operating in conjunction therewith.

  Further, the slip used for specific determination in the slip state determination device 22, that is, the difference between the rotational speed of the drive sheave 4 and the delivery speed of the suspension body 10, is obtained from Equation 2 by the slip rate δ and the rotational speed of the drive pulley. It is obtained by calculating by the product of By monitoring the change of the slip calculated in this manner and determining whether or not this exceeds a predetermined threshold, it is possible to accurately determine the slip state by quantitative slip.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described. In the second embodiment, the technique for estimating the slip state by estimating the slip based on the equation of motion of the elevator apparatus in any one state is shown. On the other hand, in the third embodiment, the slip estimation process is changed according to the car position in consideration of the fact that the state changes depending on the vertical position of the car 11, thereby improving the slip estimation accuracy. Let Other configurations and operations are the same as those in the second embodiment.

  Equation 4 shows the equation of motion of the elevator apparatus taking into account the state change due to the car position.

  In Expression 4, a differential force (unbalance weight) between the tension of the suspension body 10 on the car 11 side and the tension of the suspension body 10 on the counterweight 12 side is L ′ + f (X). X is the position of the car 11, and L ′ is a portion corresponding to the loaded weight in the car 11.

  Further, f (X) represents a change in weight due to a change in the length of the suspension body 10 suspended from the drive sheave 4 and the length of cables (power supply wiring, etc.) suspended from the car 11 at the car position. In part, it is determined as a value depending on the car position X.

  Specifically, for example, when considering the tendency that the weight of cables to which a load is applied changes in proportion to the position, the term that changes in proportion to the car position is A × X, and the car position X is 0. F (X) = A × X + B where B is a constant term for correcting the differential force between the tension of the suspension 10 on the car 11 side and the tension of the suspension 10 on the counterweight 12 side. Can be defined by a linear function such as Thereby, the error which arises under the influence of unbalance weight can be eliminated.

  In addition, cables suspended from the car 11 have an influence on the inertial mass because the suspended part becomes longer as the car position rises. Considering this, in the equation of motion, the inertial mass of the device operating in conjunction with the suspension body 10 is defined as L ′ + g (X), and the portion depending on the car position X is defined as g (X).

  This g (X) can also be defined by a linear function as in the case of f (X), for example, since the weight of the cables changes in proportion to the position if specifically determined.

  Further, in this equation of motion, the term of the resistance force is given as ± D (X) in consideration of the influence of the driving resistance force acting when the car 11 is moved up and down. The driving resistance includes a frictional force between the car 11 and the car guide rail, and a frictional force between the counterweight 12 and the counterweight guide rail. The magnitude depends on the car position. Depends on the contact state with the changing guide rail. In other words, the frictional force is affected by the local bending state of the guide rail, the vertical accuracy of the guide rail during installation, and the state of dust and oil adhering to the guide rail. Therefore, the magnitude of the frictional force varies depending on the car position. Therefore, the driving resistance force is given as D (X) in a form depending on the position X.

  Further, since the driving resistance acts in the opposite direction to the driving direction, in the equation of motion, ± D (X) is set in consideration of the reversal of positive and negative depending on the driving direction. Here, since D (X) varies depending on the contact state with the rail, there is a large variation due to individual differences between the elevator apparatuses. Therefore, by determining the change D (X) of the driving resistance force depending on the car position based on the driving force T output when the hoisting machine motor 5 is actually driven, the influence of variation due to individual differences is included. The driving resistance can be determined.

  Specifically, it is conceivable that the driving force T (X) that changes depending on the position is acquired and used based on Expression 5 derived from Expression 4.

  In particular, when traveling at a constant speed, the acceleration / deceleration is ignored, and both the time derivative of V and the time derivative of W can be treated as 0, so the relationship of Equation 6 is substantially established.

  In this equation, ± D (X) is inverted between positive and negative depending on the traveling direction. Therefore, the driving force and the car position relationship Tup (X) when traveling in the upward direction, and the driving force and the car position relationship Tdn when traveling in the downward direction. (X) is obtained as shown in Equation 7.

  Expression 8 is obtained by the difference between the two expressions of Expression 7, and the relation D (X) corresponding to the car position of the driving resistance force can be determined by the arithmetic processing shown in Expression 8.

  Further, f (X) can be determined by performing the arithmetic processing shown in Expression 9 obtained by the sum of both expressions of Expression 7.

  Although f (X) is a characteristic determined by the structure of the elevator device, it is determined not only by eliminating the structural error between the design and the actual system by determining it using the actually measured driving force. The error of the loading weight L ′ in the car 11 detected by the device 14 can also be corrected.

  Note that a slight slip may occur due to a change in the friction state between the drive sheave 4 and the suspension body 10 over time, and the time differentiation of V and W may not be strictly zero. Therefore, when the frictional state is healthy, it is desirable to determine D (X) and f (X) at the initial stage of installing the elevator device, for example, in order to reduce the calculation error of the slip ratio.

  On the other hand, g (X) can be determined by performing the arithmetic processing of Expression 10 that can be derived as a relational expression in which the time derivative of V is not 0 in Expression 5, that is, a relational expression including acceleration / deceleration.

  Here, the slip ratio δ is required to determine g (X), but in the same way as the signal processing through the loop path shown in the second embodiment, the processing before the previous cycle is performed periodically. The slip rate δ obtained as a result may be used.

  In addition, as an example of f (X) and g (X), a linear function depending on the car position X is given. However, each model can be arbitrarily selected according to actual characteristics, and can be a multi-order function or an exponential function. It is also possible to approximate with similar tendency characteristics such as, and it is also possible to save a value corresponding to the car position X as a data example and use it at the time of calculation.

  Further, the car position X can be grasped as an absolute position by accumulating the movement amount of the car 11 by the rotation detector 8 from a reference position such as a floor stop position in a normal state where no slip occurs.

  Expression 11 shows a relational expression of the slip ratio δ in consideration of the state change due to the car position determined as described above.

  FIG. 16 shows a block diagram for constantly estimating the slip ratio δ based on the equation 11. The definition and calculation processing of each block in FIG. 16 are the same as those in FIG. 15, and an output of the slip ratio δ can be obtained by the processing defined by this block.

  In such an elevator apparatus, the slipping behavior between the drive sheave 4 and the suspension body 10 can be grasped with higher accuracy by the estimation process that takes into consideration the state that fluctuates depending on the position of the car. It can be carried out with high accuracy.

  Up to this point, the driving resistance force has been treated as a characteristic that depends only on the position X of the car as D (X), but is estimated by taking D (X, V) as a characteristic that depends on the speed V. The accuracy can be further improved. In this case, estimation accuracy can be improved by replacing D (X) with D (X, V) in the estimation formula for estimating slip and weight. The variation term D (X, V) may be a characteristic that linearly depends on the velocity V or may be treated as a non-linear characteristic.

  In the process of determining D (X, V), driving with driving patterns having different rated speeds to acquire driving force information corresponding to each rated speed, and determining a variation term based on the respective driving force information Can do. Specifically, for example, when processing is performed assuming that D (X, V) is a characteristic that is linearly dependent on the speed V, first, driving is performed with two operation patterns of rated speeds V1 and V2, and driving in a constant speed section, respectively. Get force information.

  These two pieces of information are constant values although their speeds are different from each other, so that they are not affected by the change in speed, but are affected by the change in the position X of the car. Therefore, first, by the same processing as in the second embodiment, the driving resistance force depending on the car position X for each speed is D (X, V1) for the rated speed V1 and D (X for the rated speed V2). X, V2). Based on these, D (X, V) considering linear dependence on speed can be determined by the following equation.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, when an error component is included in the slip calculated in the slip state determination device 22 of the second or third embodiment, the error is removed and a more accurate slip behavior determination is realized. Other configurations and operations are the same as those in the second or third embodiment.

  FIG. 17 is a graph for explaining a method of correcting the slip amount in the elevator apparatus according to the fourth embodiment. The slip behavior before correction and the corrected slip behavior estimated by the method shown in the second or third embodiment are shown in FIG. Is shown. In addition, this example is a behavior example in the case where a local large slip occurs due to a local abnormal state, and particularly when the load weight information used for slip estimation and the detected driving force information include an error. is there.

  The inertial mass does not normally fluctuate, and the amount of rotation of the hoisting machine 3 is also detected by an encoder or the like, so that an error hardly occurs. On the other hand, since the driving force of the hoisting machine motor 5 and the load weight detected by the scale device 14 are likely to contain errors, it is possible to realize a more accurate slip determination by correcting this effect.

  The error included in the driving force of the hoist motor 5 and the load weight detected by the scale device 14 appears as a slip error that increases in proportion to time in the estimated slip. Therefore, as a specific process for removing the influence of the error, an estimation is made so that it coincides with the slope of the slip detected by the detected plate detector 19b at the timings t1 and t2 when it passes through the detected plate 19a. The inclination with the obtained slip is corrected. Thereby, the estimated slip behavior can be corrected with high accuracy.

  Specifically, a function that changes the slope of the slip Y obtained by the estimation depending on the time t is expressed by the following equation 13, and the slope of the slip Y ′ detected by the position sensor 19 changes depending on the time t. The function is obtained as the following Expression 14.

  Y = α1 × t + β1 Equation 13

  Y ′ = α2 × t + β2 Expression 14

  Then, correction can be performed by subtracting the slip difference value of each time calculated by Expression 14 from the estimated slip of each time before correction.

  (Α1-α2) × t + (β1-β2) Equation 15

  Further, as one configuration for detecting slipping when passing through the detection plate 19a, for example, as shown in FIG. 2, a detection plate 19a having a predetermined length installed in the hoistway 1 is provided in the car 11. A position sensor 19 is used which is detected by the detected plate detector 19b.

  In such a configuration, slipping when passing through one detected plate 19a is obtained by capturing two points of the car position where the detected plate 19a is detected and the car position where the detected plate 19a is no longer detected when passing through the detected plate 19a. Can be calculated. Specifically, the detected plate detector 19b passes through the detected plate 19a by comparing the rotation amount of the drive sheave 4 while passing through these two points with the length of the detected plate 19a. Slip can be detected at timings t1 and t2.

The position sensor is not limited to the combination of the detected plate 19a and the detected plate detector 19b.
Moreover, the layout of the whole elevator apparatus is not limited to the layout of FIG. For example, the present invention can also be applied to a 2: 1 roping type elevator apparatus and an elevator apparatus in which a hoisting machine is installed at the lower part of a hoistway.
Furthermore, the present invention can be applied to all types of elevator devices such as machine room-less elevators, double deck elevators, and one-shaft multi-car elevators in which a plurality of cars are arranged in a common hoistway.

The state determination processing device 23 has the same functions of the slip detection device 21 and the slip state determination device 22 as those in the first, second, third, or fourth embodiment.
