  DESCRIPTION OF EMBODIMENTS Embodiments of a long object shake detector control device and an elevator system according to the present invention will be described below in detail with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 is an explanatory diagram illustrating a building including the elevator system according to the first embodiment. As shown in FIG. 1, the elevator system 10 of this embodiment is provided in a building 1 as a building. The elevator system 10 includes a plurality of elevator apparatuses 11. In addition, the elevator apparatus 11 may be called a bank. Each elevator apparatus 11 includes a passenger car 12, a hoistway 13, a traveling apparatus 14, a counterweight 15, a main rope 16a, a compen- sion rope 16b, and an elevator control apparatus 18, respectively. The passenger basket 12 is a box for accommodating passengers and luggage. The hoistway 13 is a space for the riding basket 12 to travel, and is a space formed by the bottom surface 13a, the top surface 13b, and the four side surfaces 13c.

  The traveling device 14 includes a main sheave 14a, a sorashishi sheave 14b, and a compensatory sheave 14c. The main sheave 14a and the soft sieve 14b are provided in the machine chamber 17a so as to be rotatable. The main sheave 14a rotates when the rotational force of the output shaft of the motor is transmitted. The machine room 17 a is a room provided in the building 1. The machine room 17 a is disposed on the upper surface 13 b side of the hoistway 13. The compensatory 14 c is provided so as to be able to rotate toward the bottom surface 13 a of the hoistway 13. The counterweight 15 is a weight having a mass approximately equal to the mass of the ride basket 12. More specifically, the weight of the riding basket 12 when the loading capacity of the riding basket 12 is about 50% of the maximum loading capacity (the total of the weight of the riding basket 12 itself and the mass of passengers and luggage in the riding basket 12) ) And the mass of the counterweight 15 are balanced. The counterweight 15 reduces the load on the traveling device 14 by balancing with the riding basket 12.

  The main rope 16 a is a rope for lifting the riding basket 12. One end of the main rope 16a is connected to the riding basket 12, and the other end is connected to the counterweight 15 via the main sheave 14a and the sorashishisheb 14b. The compensation rope 16b has a mass approximately equal to the mass of the main rope 16a. The compen- sion rope 16b is connected at one end to the riding basket 12 and at the other end to the counterweight 15 via the compensatory 14c. The compensation rope 16b balances with the main rope 16a to reduce the load on the traveling device 14.

  The elevator control device 18 is provided in the machine room 17a. The elevator control device 18 controls the operation of the motor of the traveling device 14 and controls the operation of the motor for driving the cage door of the riding cage 12. Further, the elevator control device 18 controls the operation of the display device provided at the platform 12 and the landings on each floor of the building 1 and acquires signals from the switches 12 and various sensors provided at the platform 12 and the platform.

  FIG. 2 is an explanatory diagram illustrating the entire elevator system according to the first embodiment. The elevator system 10 of the present embodiment further includes an elevator control device 19 shown in FIG. 2 and a long object shake sensor 20. The elevator control device 19 is provided in the central management room 17b. The central management room 17 b is a room provided in the building 1. The elevator control device 19 is a device for managing and controlling the plurality of elevator devices 11 in an integrated manner. The elevator control device 19 is electrically connected to the plurality of elevator control devices 18. And the elevator control apparatus 19 outputs the signal as a command to the elevator control apparatus 18, or acquires the signal which shows the driving | running state of each elevator apparatus 11 from the elevator control apparatus 18. FIG.

  The long object shake sensor 20 includes an acceleration sensor 21 and a long object shake sensor control device 30. The acceleration sensor 21 is a device that outputs the shaking of the building 1 as an electrical signal. The acceleration sensor 21 detects the acceleration of itself (acceleration sensor 21), that is, detects the acceleration of the portion of the building 1 where the self (acceleration sensor 21) is provided. The acceleration sensor 21 outputs the detected acceleration as an electrical signal. The acceleration sensor 21 is provided in a predetermined part of the building 1 that is separated from the ground G shown in FIG. However, when the building 1 swings, the building 1 swings with the ground G as a fulcrum. Therefore, when the building 1 is shaken in the primary mode due to long-period ground motion or strong wind, the uppermost shake is the largest. In addition, it is a premise that the long object shake detector 20 detects the vibration of the primary mode of the building 1 caused by long-period ground motion or strong wind. Therefore, the long object shake detector 20 includes a low-pass filter that blocks an input having a frequency higher than the frequency at the time of shaking in the primary mode. Thereby, the long object shake detector 20 senses only the shake in the primary mode.

  The acceleration sensor 21 is required to have higher detection accuracy as the acceleration to be detected becomes smaller. That is, the acceleration sensor 21 is easier to detect as the acceleration to be detected is larger. Therefore, the acceleration sensor 21 has a greater acceleration to be detected as the distance from the ground G to itself (acceleration sensor 21) increases, and therefore, it becomes easier to detect the acceleration of the portion where the acceleration sensor 21 is provided. Therefore, in this embodiment, the acceleration sensor 21 is arrange | positioned at the machine room provided in the uppermost part of the building 1, for example. The top of the building 1 is the top floor of the building 1 or the roof of the building 1. Further, the top floor of the building 1 includes not only the top floor of the building 1 but also a floor close to the top floor of the building 1. The floor close to the top floor of the building 1 is, for example, 10% of the top floor side of the number of floors the building 1 has. By providing the acceleration sensor 21 at the top of the building 1, the long object shake detector 20 can reduce the detection accuracy required for the acceleration sensor 21.

  The acceleration sensor 21 is configured by a combination of a first acceleration sensor 21a and a second acceleration sensor 21b. The first acceleration sensor 21a detects the acceleration in the first direction of itself (the first acceleration sensor 21a). The second acceleration sensor 21b detects the acceleration in the second direction of itself (second acceleration sensor 21b). The first direction and the second direction are horizontal directions that are orthogonal to each other. The acceleration sensor 21 vector-synthesizes the acceleration detected by the first acceleration sensor 21a and the acceleration detected by the second acceleration sensor 21b, so that the portion of the building 1 on the horizontal plane of the portion where the acceleration sensor 21 is provided. The acceleration of is detected.

  FIG. 3 is a block diagram illustrating functions of the sensor control device according to the first embodiment. As shown in FIG. 2, the long object shake detector control device 30 of the present embodiment is provided at the top of the building 1 together with the acceleration sensor 21. The long object shake detector control device 30 is a computer. As shown in FIG. 3, the long object shake detector control device 30 includes an input / output unit 31, an information storage unit 32, and a processing unit 33. In the long object shake sensor control device 30 of the present embodiment, one device (computer) realizes each of these functions. The long object shake sensor control device 30 performs, for example, each of these functions. Each function may be realized by electrically connecting a plurality of devices (computers) that are separately realized. The input / output unit 31 may be referred to as I / O (Input / Output). The input / output unit 31 receives a signal input or outputs a signal. The input / output unit 31 is electrically connected to the acceleration sensor 21 and the elevator control device 19.

  The information storage unit 32 stores a program in which the content of the procedure executed by the processing unit 33 and the order in which each procedure is executed, and information (data) necessary for executing the program. The processing unit 33 is a CPU (Central Processing Unit). The processing unit 33 includes an information acquisition unit 34, a calculation unit 35, and a signal generation unit 36. The information acquisition unit 34 acquires information from the information storage unit 32. In addition, the information acquisition unit 34 acquires a signal from the acceleration sensor 21 connected to the input / output unit 31. The signal acquired from the acceleration sensor 21 is a signal representing the acceleration of the acceleration sensor 21, that is, the magnitude of the acceleration of a predetermined part of the building 1. The calculation unit 35 compares the acceleration acquired by the information acquisition unit 34 from the acceleration sensor 21 with the predetermined acceleration acquired from the information acquisition unit 34. The signal generation unit 36 generates a warning signal for the elevator control device 19 to acquire. The signal generation unit 36 generates one or more types of warning signals. In the present embodiment, three types of warning signals are generated: a high signal, a low signal, and an extra low signal.

  When the building 1 shown in FIG. 1 is shaken and the long object swings in the primary mode, the long object swings with the central portion in the longitudinal direction (vertical direction) as a belly. That is, in the primary mode, the amount of shake of the long object has a maximum value in the central portion in the longitudinal direction (vertical direction). The amount of shaking of the long object varies depending on the magnitude of shaking of the building 1. That is, the shake amount of the long object changes depending on the magnitude of the acceleration detected by the acceleration sensor 21. Moreover, when the shaking of the building 1 continues, the long object may start to resonate. Thereby, the shake amount of a long object changes also with the time when the shake of the building 1 continues. The long object shake detector 20 individually predicts the magnitude of the shake amount of the long object included in each elevator apparatus 11 shown in FIG. 1 based on the acceleration and the duration of the shake. There is a feature.

  FIG. 4A is a flowchart illustrating the first half of a series of procedures executed by the sensor control device according to the first embodiment. FIG. 4-2 is a flowchart illustrating the second half of a series of procedures executed by the sensor control device of the first embodiment. Prior to describing a series of procedures executed by the long object shake sensor control device 30, the four elevator devices 11 shown in FIG. 1 are distinguished for convenience of explanation. Among the four elevator apparatuses 11 shown in FIG. 1, the one in which the bottom surface 13 a of the hoistway 13 is located on the ground G and the upper surface 13 b of the hoistway 13 is located on the uppermost floor of the building 1 is referred to as a first elevator apparatus 11 a. Among the three elevator apparatuses 11 excluding the first elevator apparatus 11a, the one in which the bottom surface 13a of the hoistway 13 is located in the middle of the building 1 in the vertical direction and the upper surface 13b of the hoistway 13 is located in the vicinity of the top floor. It is called 2 elevator apparatus 11b. Of the two elevator apparatuses 11 excluding the first elevator apparatus 11a and the second elevator apparatus 11b, the bottom surface 13a of the hoistway 13 is located on the ground G, and the upper surface 13b of the hoistway 13 is located on the upper side in the vertical direction. This is called a third elevator apparatus 11c. Of the four elevator apparatuses 11, ones other than the first elevator apparatus 11a to the third elevator apparatus 11c are referred to as a fourth elevator apparatus 11d.

  The long object is, for example, a main rope 16a, a compensation rope 16b, and a wiring material. The wiring material is a wire material for electrically connecting the electric device provided in the car 12 and the elevator control device 18. Even if the shaking of the building 1 is constant, the amount of swing of the long object varies from one elevator device 11 to another. For example, in the case of the elevator system 10 of the present embodiment, long objects included in the order of the first elevator device 11a, the second elevator device 11b, the third elevator device 11c, and the fourth elevator device 11d tend to swing. Long objects are more likely to shake as the natural frequency of the building 1 and the natural frequency of the long object become closer. The natural frequency of the rope is determined by the rope length, rope weight, rope tension, and the like.

  Therefore, even if the same elevator apparatus 11 is used, depending on the position of the passenger car 12, the long object may or may not swing. In addition, the position of the riding basket 12 when the shaking of the long object can be reduced is referred to as an “evacuation floor” of the elevator apparatus 11. Moreover, the amount of shake tends to increase as the long object is arranged on the upper side in the vertical direction. The reason that the amount of shake tends to increase as the long object is arranged on the upper side in the vertical direction is that when the building 1 is shaken, the amount of displacement of the building 1 is larger in the upper part in the vertical direction. Depending on the length of the long object, the long object included in the third elevator apparatus 11c may have a greater amount of vibration than the long object included in the second elevator apparatus 11b.

  Next, each value shown in FIGS. 4A and 4B, which is a numerical value handled by the long object shake detector control device 30, will be described. α is the acceleration of itself (acceleration sensor 21) detected by the acceleration sensor 21 shown in FIG. 2 and is the acceleration of a predetermined part of the building 1. The predetermined acceleration α11, the predetermined acceleration α12, the predetermined acceleration α13, the predetermined acceleration α21, the predetermined acceleration α22, the predetermined acceleration α23, the predetermined acceleration α31, and the predetermined acceleration α32 shown in FIGS. The predetermined acceleration α33 is a value stored in advance in the information storage unit 32 shown in FIG. Each value of the predetermined accelerations α11 to α13 is a value used to divide the magnitude of the current shake amount of the long object included in the first elevator apparatus 11a shown in FIG. 1 into a plurality of stages. The predetermined accelerations α21 to α23 are values used to divide the current amount of shake of the long object provided in the second elevator apparatus 11b shown in FIG. 1 into a plurality of stages. The predetermined accelerations α31 to α33 are values used to divide the current amount of shake of the long object provided in the third elevator apparatus 11c shown in FIG. 1 into a plurality of stages.

  In the present embodiment, the shake amount of the long object is classified from the first stage to the third stage. The greater the amount from the first stage to the third stage, the greater the amount of shake of the long object, and the longer the object becomes more likely to come into contact with the side surface 13c of the hoistway 13 shown in FIG. Assuming that the distance from the long object to the side surface 13c of the hoistway 13 shown in FIG. 1 is 1000 mm, the long object's deflection amount is the first when the deflection amount of the long object exceeds a predetermined amount of 50 mm. It becomes a stage. Further, when the shake amount of the long object exceeds a predetermined amount of 500 mm, the shake amount of the long object becomes the second stage. Further, when the amount of shake of the long object exceeds a predetermined amount of 800 mm, the amount of shake of the long object becomes the third stage.

  In this embodiment, even if the magnitude of the shaking of the building 1 is the maximum value assumed, the magnitude of the shaking amount of the long object included in the fourth elevator apparatus 11d is an allowable size (fourth). It is assumed that the long object included in the elevator apparatus 11d is a size that does not contact the side surface 13c of the hoistway 13). Therefore, the long object shake detector 20 does not monitor the shake amount of the long object of the fourth elevator device 11d, but monitors the shake amount of the long object of the first elevator device 11a to the third elevator device 11c. Shall. In other words, the long object shake detector 20 is not wary of the elevator control devices 18 of the first elevator device 11a to the third elevator device 11c without outputting a warning signal to the elevator control device 18 of the fourth elevator device 11d. Output a signal.

  Next, the continuous time counter t11, the continuous time counter t12, the continuous time counter t13, the continuous time counter t21, the continuous time counter t22, and the continuous time counter t23 shown in FIGS. The duration counter t31, duration counter t32, and duration counter t33 will be described. Each value of the continuation time counters t11 to t33 is a value representing the time that has elapsed since the acceleration sensor 21 started to shake. Specifically, the duration time counter t11 is a variable for measuring the time that has elapsed since the acceleration α is equal to or greater than the predetermined acceleration α11. The duration counter t12 is a variable for measuring the time that has elapsed since the acceleration α is equal to or greater than the predetermined acceleration α12. The duration time counter t13 is a variable for measuring the time that has elapsed since the acceleration α is equal to or greater than the predetermined acceleration α13. The same applies to the values of the continuation time counters t21 to t33.

  The predetermined time t11a, the predetermined time t12a, the predetermined time t13a, the predetermined time t21a, the predetermined time t22a, the predetermined time t23a, the predetermined time t31a, and the predetermined time t32a illustrated in FIGS. The predetermined time t33a is a value stored in advance in the information storage unit 32 shown in FIG. Each value of predetermined time t11a-t13a is a value used in order to divide the magnitude | size of the present amount of shake of the long object with which the 1st elevator apparatus 11a shown in FIG. The predetermined times t21a to t23a are values used to divide the current swing amount of the long object provided in the second elevator apparatus 11b shown in FIG. 1 into a plurality of stages. The predetermined times t31a to t33a are values used to divide the current swing amount of the long object provided in the third elevator apparatus 11c shown in FIG. 1 into a plurality of stages.

  Next, each value of the predetermined accelerations α11 to α33 and each value of the predetermined times t11a to t33a will be described in more detail. When the current acceleration α is equal to or greater than the predetermined acceleration α11, the predetermined acceleration α11 may be in a third stage when the amount of shake of the long object included in the first elevator apparatus 11a shown in FIG. 1 exceeds the predetermined amount. It is a value that can be determined to exist. Then, the predetermined time t11a is a state in which the current acceleration α is equal to or greater than the predetermined acceleration α11, and when the duration counter t11 is equal to or greater than the predetermined time t11a, the long object shake included in the first elevator apparatus 11a. It is a value that can be determined when the amount exceeds the predetermined amount and becomes the third stage. Similarly, the predetermined acceleration α21 and the predetermined time t21a are values for determining whether or not the shake amount of the long object included in the second elevator apparatus 11b exceeds the predetermined amount to enter the third stage. Similarly, the predetermined acceleration α31 and the predetermined time t31a are values for determining whether or not the swing amount of the long object included in the third elevator apparatus 11c exceeds the predetermined amount and enters the third stage.

  The predetermined acceleration α12 may be a second stage when the current acceleration α becomes equal to or greater than the predetermined acceleration α12, and the amount of shake of the long object included in the first elevator apparatus 11a shown in FIG. 1 exceeds the predetermined amount. It is a value that can be determined to exist. The predetermined time t12a is a state in which the current acceleration α is equal to or greater than the predetermined acceleration α12, and the long-body swing of the first elevator apparatus 11a is detected when the duration counter t12 is equal to or greater than the predetermined time t12a. It is a value that can be determined when the amount exceeds the predetermined amount and becomes the third stage. Similarly, the predetermined acceleration α22 and the predetermined time t22a are values for determining whether or not the shake amount of the long object included in the second elevator apparatus 11b exceeds the predetermined amount to enter the second stage. Similarly, the predetermined acceleration α32 and the predetermined time t32a are values for determining whether or not the amount of shake of the long object included in the third elevator apparatus 11c exceeds the predetermined amount and enters the second stage.

  The predetermined acceleration α13 is likely to be in the first stage when the current acceleration α becomes equal to or greater than the predetermined acceleration α13, and the amount of shake of the long object included in the first elevator apparatus 11a shown in FIG. It is a value that can be determined to exist. Then, the predetermined time t13a is a state in which the current acceleration α is equal to or greater than the predetermined acceleration α13, and when the duration counter t13 is equal to or greater than the predetermined time t13a, the long object shake included in the first elevator apparatus 11a. It is a value that can be determined that the amount exceeds the predetermined amount and becomes the first stage. Similarly, the predetermined acceleration α23 and the predetermined time t23a are values for determining whether or not the shake amount of the long object included in the second elevator apparatus 11b exceeds the predetermined amount and enters the first stage. Similarly, the predetermined acceleration α33 and the predetermined time t33a are values for determining whether or not the swing amount of the long object included in the third elevator apparatus 11c exceeds the predetermined amount and enters the first stage.

FIG. 5 is a chart for calculating the amount of displacement at the top of the building based on the height of the building and the acceleration at the top of the building. The unit of the numerical value of the colored portion in FIG. 5 (the displacement D at the top of the building 1) is gal (1 gal = 0.01 m / s ² ). The natural period T (s) of the building 1 shown in FIG. 5 and the height (m) of the building 1 are approximately T = 0.025 × H. The acceleration α (m / s ² ) at the top of the building 1, the natural period T (s) of the building 1, and the displacement D (m) at the top of the building 1 are α = D × (2 × π / T) ²

  The values of the predetermined accelerations α11 to α33 and the values of the predetermined times t11a to t33a are determined based on the results of analysis performed in advance. This analysis is based on the time during which the shaking of the building 1 continues and the first elevator device 11a to the third elevator device 11c for each displacement amount of the portion (predetermined part of the building 1) where the acceleration sensor 21 of the building 1 is provided. The relationship with each shake amount of the long object provided is calculated. The displacement amount of the uppermost part of the building 1 which is a predetermined part of the building 1 is calculated by applying the acceleration of the uppermost part of the building 1 to the chart shown in FIG. Specifically, for example, if the height of the building 1 is 400 m and the acceleration at the top of the building 1 is 3.9 gal, the displacement (amplitude) of the top floor of the building 1 is 100 mm. Even when the acceleration at the top of the building 1 is the same 3.9 gal, for example, when the height of the building 1 is 180 m, the displacement of the top of the building 1 is 20 mm.

  Next, for each displacement amount of the predetermined part of the building 1, the displacement amount of the long object included in each of the first elevator device 11 a to the third elevator device 11 c shown in FIG. 1 and the duration time of the shaking of the building 1 Analyze the relationship. An example of the analysis result is shown in FIG. FIG. 6 shows the amount of displacement of the center part in the longitudinal direction of the long object, the amount of displacement of the upper part 1/4 in the longitudinal direction of the elongated object, and the lower part 1/4 part in the longitudinal direction of the elongated object. The amount of displacement is shown. The upper part and the lower part in the longitudinal direction of the long object are parts that become nodes of deflection of the long object. Here, in the case of the elevator apparatus 11 shown in FIG. 1, each elevator apparatus 11 has four long objects. Below, the upper part and the lower part of the longitudinal direction of each elongate object are demonstrated concretely.

  The first long object is a part of the main rope 16a. In this long object, the contact point between the main rope 16a and the main sheave 14a is the upper part, and the contact point between the main rope 16a and the riding basket 12 is the lower part. The second long object is a part of the main rope 16a. In this long object, the contact point between the main rope 16a and the solacey sheave 14b is the upper part, and the contact point between the main rope 16a and the counterweight 15 is the lower part. The third long object is a part of the compen- sion rope 16b. In this long object, the contact point between the compen- sion rope 16b and the counterweight 15 is at the upper part, and the contact point between the compen- sion rope 16b and the compensatory 14c is at the lower part. The fourth long object is a part of the compensation rope 16b. In this long object, the contact point between the compen- sion rope 16b and the riding basket 12 is the upper part, and the contact point between the compen- sion rope 16b and the compensatory 14c is the lower part.

  The amount of deflection of the long object is the amount of displacement at the top of the building 1, the height of the building 1, the vertical position of the upper part of the long object, the vertical position of the lower part of the long object, It varies depending on the density of the long object and the tension applied to the long object. Therefore, in this analysis, these values are input to the computer as parameters. Note that the computer here is not the computer of the long object shake detector control device 30. Moreover, the tension | tensile_strength loaded on a long thing is a value which may change with the number of the passengers in the riding basket 12 shown in FIG. The position in the vertical direction of the upper part of the long object and the position in the vertical direction of the lower part of the long object also vary depending on the position of the riding basket 12. In this analysis, the amount of deflection of the long object is the maximum for the tension applied to the long object, the vertical position of the upper part of the long object, and the vertical position of the lower part of the long object. Use such values. For example, as the position in the vertical direction of the upper part of the long object and the position in the vertical direction of the lower part of the long object, values when the riding basket 12 is at a position other than the retreat floor are used.

  FIG. 6 is a graph showing a relationship between the time during which the shaking of the building in which the displacement amount at the top of the building is 15 mm continues and the shaking amount of each part of the long object included in the first elevator apparatus. When this analysis is performed with the parameters set in this way, for example, an analysis result as shown in FIG. 6 is calculated by the computer. Note that the computer here is not the computer of the long object shake detector control device 30. From the analysis result shown in FIG. 6, when the displacement amount of the uppermost part of the building 1 which is a predetermined part of the building 1 is 15 mm, if this shaking continues for 405 seconds, the shaking amount of the central portion in the longitudinal direction of the long object Becomes 1000 mm. That is, if the distance between the long object and the side surface 13c of the hoistway 13 shown in FIG. 1 is 1000 m, and the shaking of the building 1 where the displacement amount of the uppermost part of the building 1 is 15 mm continues for 405 seconds, the long object Will contact the side surface 13c of the hoistway 13.

  As described above, in the analysis of this embodiment, the response of the time history is analyzed for an arbitrary position in the height direction of the building 1. In this analysis, the loading condition of the riding car 12 (which affects the rope tension) and the position of the riding car 12 (which affects the rope length and its own weight) are changed to resonate with the primary mode of the building 1. Ask if there is. Then, in this analysis, the length of the elevator apparatus 11 provided by using the analysis result of the time history response of the building 1 under the position of the car 12 where the resonance phenomenon occurs and the loading condition (dangerous floor: may be plural). Analyze the time history response of the swing of an object. Thereby, the magnitude and time of the growth of the swing of the long object (rope) are grasped. Based on the above analysis, the values of the predetermined accelerations α11 to α33 and the values of the predetermined times t11a to t33 shown in FIGS. 4-1 and 4-2 are set.

  In step ST01 illustrated in FIG. 4A, the information acquisition unit 34 illustrated in FIG. 3 acquires the acceleration α by acquiring a signal from the acceleration sensor 21 via the input / output unit 31. Next, in step ST11 shown in FIG. 4A, the calculation unit 35 shown in FIG. 3 determines whether or not the acceleration α is equal to or greater than the predetermined acceleration α11. Specifically, first, the information acquisition unit 34 illustrated in FIG. 3 acquires the predetermined acceleration α11 from the information storage unit 32. Then, the calculation unit 35 subtracts the predetermined acceleration α11 from the acceleration α. When the value of the calculation result is 0 or a positive value, the calculation unit 35 determines that the acceleration α is equal to or greater than the predetermined acceleration α11. When the value of the calculation result is a negative value, the calculation unit 35 determines that the acceleration α is not greater than or equal to the predetermined acceleration α11.

  When the acceleration α is equal to or greater than the predetermined acceleration α11 (Yes in step ST11), in step ST12, the calculation unit 35 sets a value obtained by adding 1 to the duration counter t11 as a new duration counter t11. For example, even if the duration counter t11 is the same, the time (seconds) indicated by the duration counter t11 varies depending on the processing speed of the processing unit 33. Therefore, the values of the predetermined times t11a to t33a are also adjusted in magnitude according to the processing speed of the processing unit 33. In a specific procedure executed by the long object shake detector control device 30 in step ST12, the information acquisition unit 34 first acquires the duration counter t11 from the information storage unit 32. Then, the calculation unit 35 adds 1 to the duration counter t11. Then, the information storage unit 32 stores the duration counter t11 added with 1 as a new duration counter t11.

  Next, in step ST13, the computing unit 35 determines whether or not the duration counter t11 is equal to or longer than the predetermined time t11a. Specifically, first, the information acquisition unit 34 illustrated in FIG. 3 acquires the predetermined time t11a from the information storage unit 32. And the calculating part 35 subtracts predetermined time t11a from duration counter t11. When the value of the calculation result is 0 or a positive value, the calculation unit 35 determines that the duration counter t11 is equal to or greater than the predetermined time t11a. When the value of the calculation result is a negative value, the calculation unit 35 determines that the duration counter t11 is not greater than or equal to the predetermined time t11a.

  When the duration counter t11 is not equal to or longer than the predetermined time t11a (No in Step ST13), the long object shake detector control device 30 executes a series of steps after Step ST21 without executing Step ST14 and Step ST15. . The long object shake detector control device 30 starts the process from step ST01 again after executing a series of steps after step ST21. When the calculation unit 35 repeatedly executes step ST12 and the duration counter t11 becomes equal to or longer than the predetermined time t11a (step ST13, Yes), the signal generation unit 36 shown in FIG. 3 generates the high signal S11 in step ST14. The input / output unit 31 shown in FIG. 3 starts outputting the high signal S11 to the elevator control device 19. The high signal S11 is a warning signal indicating that the amount of shake of the long object of the first elevator apparatus 11a shown in FIG. 1 is the third stage. If the high signal S11 has already been output when step ST14 is executed again, the signal generator 36 maintains the generation of the high signal S11 and the input / output unit 31 outputs the high signal S11 to the elevator control device 19. Maintain output. When step ST14 is executed, the long object shake detector control device 30 executes a series of procedures after step ST41.

  By executing the above procedure, when the acceleration α is equal to or greater than the predetermined acceleration α11 and the duration counter t11 is equal to or greater than the predetermined time t11a, that is, the acceleration α of the predetermined part of the building 1 is equal to or greater than the predetermined acceleration α11. Is continued for a predetermined time or longer, the long shake detector 20 continues to output the high signal S11 to the elevator control device 19 while satisfying the condition. When the elevator control device 19 shown in FIG. 2 receives the high signal S11, the elevator control device 19 delivers the high signal S11 to the elevator control device 18 of the first elevator device 11a. In the case of an elevator system that does not include the elevator control device 19, when the long object shake sensor 20 and the elevator control device 18 are directly electrically connected, the long object shake sensor 20 outputs the high signal S11. Directly output to the elevator control device 18 of the one elevator device 11a. When acquiring the high signal S11, the elevator control device 18 executes a procedure set in advance to be executed when the high signal S11 is acquired. Below, an example of the procedure which the elevator control apparatus 18 performs when acquiring the high signal S11 is demonstrated.

  FIG. 7 is a flowchart showing a series of procedures executed by the elevator control device when a high signal is acquired. First, in step ST201, the information acquisition unit included in the elevator control device 18 acquires the current position of the passenger car 12 illustrated in FIG. Next, in step ST202, the calculation unit included in the elevator control device 18 determines whether or not the current position of the passenger car 12 is the retreat floor. The retreat floor is a position of the passenger car 12 that can reduce the shake of a long object included in the elevator apparatus 11. The retreat floor varies depending on the height of the building 1 (the number of floors) and the specifications of the elevator apparatus 11, but is the position of the central portion 4/6 of the hoistway 13 overall height, for example.

  When the current position of the passenger car 12 is the retreat floor (step ST202, Yes), the travel device control unit included in the elevator control device 18 stops the travel device 14 in step ST203. When the current position of the passenger car 12 is not the retreat floor (No in Step ST202), the travel device control unit included in the elevator control device 18 drives the travel device 14 and moves the passenger car 12 to the retreat floor in Step ST204. Let If step ST203 or step ST204 is performed, the elevator control apparatus 18 will complete | finish execution of a series of procedures. When the elevator control device 18 executes the series of steps described above when the high signal S11 is acquired, the first elevator device 11a shown in FIG. The basket 12 moves to a position where it can wait or reduce the shake amount of a long object. Therefore, the 1st elevator apparatus 11a can reduce the amount of shake of a long thing, and can reduce a possibility that a long thing contacts the side 13c of the hoistway 13. FIG.

  Returning to FIG. 4A, the procedure executed by the long object shake detector control device 30 when a negative determination is made in step ST11 will be described. When the acceleration α is not equal to or higher than the predetermined acceleration α11 (No in step ST11), the signal generation unit 36 stops generating the high signal S11 and the input / output unit 31 outputs the high signal S11 to the elevator control device 19 in step ST15. Stop the output of. If the high signal S11 is not output when step ST15 is executed again, the signal generation unit 36 maintains the generation stop state of the high signal S11 and the input / output unit 31 outputs a high signal to the elevator control device 19. The output stop state of S11 is maintained.

  In step ST15, the calculation unit 35 clears (sets to 0) the duration counter t11. Specifically, the calculation unit 35 sets the duration counter t11 to 0, and the information storage unit 32 stores the duration counter t11 that has reached 0 as a new duration counter t11. When step ST15 is executed, the long object shake detector control device 30 executes a series of procedures after step ST21. The elevator control device 19 illustrated in FIG. 2 stops the operation of the traveling device 14 in step ST203 illustrated in FIG. 7 while the high signal S11 is input. When the acceleration α is smaller than the predetermined acceleration α11, the long object shake detector 20 stops outputting the high signal S11 to the elevator control device 19. Thereby, the elevator control apparatus 18 of the 1st elevator apparatus 11a cannot acquire the high signal S11. Therefore, the drive of the traveling apparatus 14 is restarted and the first elevator apparatus 11a resumes normal operation.

  Step ST21 to step ST25 shown in FIG. 4A are the same as step ST11 to step ST15. However, the predetermined acceleration α11 is replaced with the predetermined acceleration α12, the duration counter t11 is replaced with the duration counter t12, the predetermined time t11a is replaced with the predetermined time t12a, and the high signal S11 is replaced with the low signal S12. The low signal S12 is a warning signal indicating that the amount of deflection of the long object of the first elevator apparatus 11a shown in FIG. 1 is in the second stage. When step ST24 is executed, the long object shake detector control device 30 executes a series of steps after step ST41. When step ST25 is executed, the long object shake detector control device 30 executes a series of steps after step ST31.

  By executing the above procedure, the acceleration α is equal to or greater than the predetermined acceleration α12, and the duration counter t12 is equal to or greater than the predetermined time t12a, that is, the acceleration α of the predetermined part of the building 1 is equal to or greater than the predetermined acceleration α12. Is continued for a predetermined time or longer, the long vibration detector 20 continues to output the low signal S12 to the elevator control device 19 while satisfying the condition. When the elevator control device 19 shown in FIG. 2 receives the low signal S12, the elevator control device 19 delivers the low signal S12 to the elevator control device 18 of the first elevator device 11a. In the case of an elevator system that does not include the elevator control device 19, when the long object shake sensor 20 and the elevator control device 18 are directly electrically connected, the long object shake sensor 20 outputs the low signal S12. Directly output to the elevator control device 18 of the one elevator device 11a.

  When acquiring the low signal S12, the elevator control device 18 stops the operation of the traveling device 14 shown in FIG. 1, for example. If the amount of deflection is the second stage, the long object is not likely to come into contact with the side surface 13c of the hoistway 13, but the elevator control device 18 stops the operation of the traveling device 14 so that the elevator device 11 High safety can be secured. Further, when the input / output unit 31 and the signal generation unit 36 shown in FIG. 3 execute step ST25 shown in FIG. 4A, the long object shake detector 20 stops the output of the low signal S12 to the elevator control device 19. To do. Thereby, the elevator control apparatus 18 of the 1st elevator apparatus 11a cannot acquire the low signal S12. Therefore, the drive of the traveling apparatus 14 is restarted and the first elevator apparatus 11a resumes normal operation.

  Step ST31 to step ST35 shown in FIG. 4A are the same as step ST11 to step ST15. However, the predetermined acceleration α11 is replaced with the predetermined acceleration α13, the duration counter t11 is replaced with the duration counter t13, the predetermined time t11a is replaced with the predetermined time t13a, and the high signal S11 is replaced with the extra low signal S13. The extra low signal S13 is a warning signal indicating that the amount of shake of the long object of the first elevator apparatus 11a shown in FIG. 1 is the first stage. When step ST34 or step ST35 is executed, the long object shake detector control device 30 executes a series of procedures after step ST41.

  By executing the above procedure, when the acceleration α is equal to or greater than the predetermined acceleration α13 and the duration counter t13 is equal to or greater than the predetermined time t13a, that is, the acceleration α of the predetermined part of the building 1 is equal to or greater than the predetermined acceleration α13. Is continued for a predetermined time or longer, the long object shake detector 20 continues to output the extra low signal S13 to the elevator control device 19 while satisfying the condition. When the elevator control device 19 shown in FIG. 2 receives the special low signal S13, it passes the special low signal S13 to the elevator control device 18 of the first elevator device 11a. In the case of an elevator system that does not include the elevator control device 19, when the long object shake sensor 20 and the elevator control device 18 are directly electrically connected, the long object shake sensor 20 outputs the extra low signal S13. It directly outputs to the elevator control device 18 of the first elevator device 11a.

  When the extra low signal S13 is acquired, the elevator control device 18 announces, for example, an announcement that senses a slight tremor, or an announcement that the ride car 12 may stop traveling if the shaking becomes strong, for example. Is output from a speaker provided in the car 12 shown in FIG. Further, when the extra low signal S13 is acquired, the elevator control device 18, for example, indicates that there is a possibility that the traveling of the riding basket 12 may stop when an image indicating that a slight tremor has been detected or when the shaking becomes strong. An image to be transmitted is displayed on a display device provided in the riding basket 12 shown in FIG. Thereby, the passenger in the riding basket 12 can prepare for the situation where the traveling device 14 stops by confirming the announcement and the image.

  Further, when the input / output unit 31 and the signal generation unit 36 shown in FIG. 3 execute step ST35 shown in FIG. 4A, the long object shake detector 20 outputs the extra low signal S13 to the elevator control device 19. Stop. Thereby, the elevator control apparatus 18 of the 1st elevator apparatus 11a cannot acquire the special low signal S13. Therefore, the 1st elevator apparatus 11a can stop the announcement in the riding basket 12, and the display of an image.

  Step ST41 to step ST65 shown in FIG. 4A are the same as step ST11 to step ST35. However, the predetermined accelerations α11 to α13 are replaced with predetermined accelerations α21 to α23, the duration counters t11 to t13 are replaced with duration counters t21 to t23, and the predetermined times t11a to t13a are replaced with predetermined times t21a to t23a. The high signal S21, the low signal S22, and the extra low signal S23 are warning signals acquired by the elevator control device 18 of the second elevator apparatus 11b. The high signal S21 output in step ST44 is a warning signal indicating that the amount of shake of the long object of the second elevator apparatus 11b shown in FIG. 1 is the third stage.

  The low signal S22 output in step ST54 is a warning signal indicating that the amount of shake of the long object of the second elevator apparatus 11b is in the second stage. The extra low signal S23 output in step ST64 is a warning signal indicating that the amount of shake of the long object of the first elevator apparatus 11a shown in FIG. 1 is the first stage. When step ST44 or step ST54 or step ST64 or step ST65 is executed, the long object shake detector control device 30 executes a series of procedures after step ST71 shown in FIG. By executing the above procedure, the long object shake detector 20 has the same effect as the effect exerted on the first elevator apparatus 11a by executing a series of steps ST11 to ST35. It can play with respect to the elevator apparatus 11b.

  Step ST71 to step ST95 shown in FIG. 4-2 are the same as step ST11 to step ST35. However, the predetermined accelerations α11 to α13 are replaced with predetermined accelerations α31 to α33, the duration counters t11 to t13 are replaced with duration counters t31 to t33, and the predetermined times t11a to t13a are replaced with predetermined times t31a to t33a. The high signal S31, the low signal S32, and the extra low signal S33 are warning signals acquired by the elevator control device 18 of the third elevator device 11c. The high signal S31 output in step ST74 is a warning signal indicating that the amount of shake of the long object of the third elevator apparatus 11c shown in FIG. 1 is the third stage.

  The low signal S32 output in step ST84 is a warning signal indicating that the amount of shake of the long object of the third elevator apparatus 11c is in the second stage. The extra low signal S33 output in step ST94 is a warning signal indicating that the amount of shake of the long object of the first elevator apparatus 11a shown in FIG. 1 is the first stage. When step ST74 or step ST84 or step ST94 or step ST95 is executed, the long object shake detector control device 30 ends the execution of a series of procedures, and again executes step ST01 shown in FIG. By executing the above procedure, the long object shake detector 20 has the same effect as the effect exerted on the first elevator apparatus 11a by executing a series of steps ST11 to ST35. It can play with respect to the elevator apparatus 11c.

  By executing a series of procedures from step ST01 shown in FIG. 4-1 to step ST95 shown in FIG. 4-2, the long-body shake detector control device 30 can detect the acceleration of a predetermined part of the building 1, It is possible to determine whether or not the amount of swing of the long object included in each of the plurality of elevator apparatuses 11 illustrated in FIG. Therefore, the long object shake detector 20 does not include a plurality of acceleration sensors 21 but includes a single acceleration sensor 21, so that each signal (a high signal, a low signal, a special signal) is transmitted to the plurality of elevator control devices 19. (Low signal) can be output. As a result, the long object shake detector 20 can reduce the number of acceleration sensors 21 necessary for ensuring higher safety of the plurality of elevator apparatuses 11. As a result, the long object shake detector 20 can reduce the cost required for the construction of the elevator system 10.

(Embodiment 2)
FIG. 8 is an explanatory diagram illustrating the entire elevator system according to the second embodiment. As shown in FIG. 8, the elevator system 40 of the present embodiment includes a long object shake sensor 41. The long object shake sensor 41 is different from the long object shake sensor 20 of the first embodiment shown in FIG. 2 in that the acceleration sensor 21 and the long object shake sensor control device 30 are provided at positions separated from each other. Specifically, the acceleration sensor 21 is provided at the top of the building 1. The long object shake detector control device 30 is provided in the central management room 17b. The acceleration sensor 21 and the long object shake detector control device 30 are electrically connected to each other through a wiring 42. The long object shake detector control device 30 and the elevator control device 19 are electrically connected to each other through three wires of a wire 43a, a wire 43b, and a wire 43c.

  The wiring 42 is a wiring for transmitting the acceleration detected by the acceleration sensor 21 as an electrical signal to the long object shake detector control device 30. The central management room 17b is generally away from the top of the building 1. Therefore, the wiring 42 is a relatively long wiring among the wirings provided in the elevator system 10. The wiring 43a is a wiring for transmitting each signal of the high signal S11 to the extra low signal S13 to the elevator control device 19. The wiring 43b is a wiring for transmitting each signal of the high signal S21 to the extra low signal S23 to the elevator control device 19. The wiring 43c is a wiring for transmitting each signal of the high signal S31 to the extra low signal S33 to the elevator control device 19. The long object shake detector control device 30 is provided in the same room as the elevator control device 19. Each of the wirings 43 a to 43 c is a relatively short wiring among the wirings provided in the elevator system 10.

  As described above, the long object shake sensor 41 of the present embodiment has the same effects as the long object shake sensor 20 of the first embodiment, and also has the following effects. The long-body shake detector 41 is configured so that the number of relatively long wires passed between the uppermost part of the building 1 and the central management room 17b is longer than that of the long-body shake sensor 20 of the first embodiment shown in FIG. Can also be reduced. Therefore, the long object shake detector 41 can more suitably reduce the cost required for the construction of the elevator system 40. Further, when the relatively long wiring material increases, the wiring (arrangement) of the wiring provided in the elevator system 40 tends to be complicated. However, the elevator system 40 can reduce the number of relatively long wires. Therefore, the long object shake detector 41 can simplify the wiring (arrangement) of the wiring provided in the elevator system 40.

  In the present embodiment, the long object shake sensor control device 30 is provided separately from the elevator control device 19, but the long object shake sensor control device 30 may be included in the elevator control device 19. In this case, the elevator control device 19 has the functions of the long object shake detector control device 30 (the functions of the input / output unit 31 to the signal generation unit 36 shown in FIG. 3). When the long object shake sensor 41 is added to the elevator system already provided in the building 1, the long object shake sensor 41 includes the long object shake sensor control device 30 and the elevator control device 19. It is preferable to provide them separately. As a result, the long object shake detector 41 can be easily introduced into the elevator system without significant changes to the elevator control device 19 already provided in the elevator system. On the other hand, when a new elevator system is introduced into the building 1, it is preferable that the long object shake sensor 41 includes the long object shake sensor control device 30 in the elevator control device 19. In this case, the long object shake detector 41 can omit one device called the long object shake detector control device 30, so that the cost required to construct the elevator system 40 can be further reduced.

(Modification)
The long object shake sensor 20 of the first embodiment shown in FIG. 2 and the long object shake sensor 41 of the second embodiment shown in FIG. 8 each include an acceleration sensor 21. Instead of the acceleration sensor 21, the long object shake detector of the modification may include a displacement sensor. A displacement sensor is a device that detects the amount of displacement of a portion where the device (displacement sensor) is provided. However, a general displacement sensor is provided with an acceleration sensor, and the amount of displacement of the portion where it is provided is derived based on the result detected by the acceleration sensor. Therefore, the long object shake detector of the modified example provided with such a displacement sensor also determines whether the shake amount of the long object provided in the elevator apparatus 11 is within an allowable range based on the acceleration. The concept is the same as that of the long object shake sensor 20 shown in FIG. 2 and the long object shake sensor 41 shown in FIG.

  On the other hand, some displacement sensors do not include an acceleration sensor. The long object shake detector of the modified example may include a displacement sensor that does not include the acceleration sensor instead of the acceleration sensor 21. This is because the displacement amount and the acceleration are related to each other as illustrated in FIG. The sensor control device for a long object shake sensor of such a modification uses a displacement amount of a portion where a displacement sensor is provided in place of the acceleration α shown in FIGS. Instead of α11 to α33, a value obtained by replacing each value of the predetermined accelerations α11 to α33 with a displacement amount is used. Thereby, the long-body shake detector of the modification provided with the displacement sensor has the same effect as the long-body shake sensor 20 shown in FIG. 2 and the long-body shake detector 41 shown in FIG. Can be played.

  As described above, the long object shake detector and the elevator control device according to the present invention are useful for the technology for determining whether or not the shake amount of the long object included in the elevator device is within a predetermined value. It is suitable for reducing the cost required to construct an elevator system.
