Description

  The present invention relates to an elevator test apparatus that verifies an elevator position control device that is an electronic substitute when a mechanical floor selector of an old elevator system that extracts a car position signal of a car is computerized.

  FIG. 3 is a diagram showing a configuration of a conventional general elevator system. In the figure, 51 is a hoisting machine comprising an electric motor and a main sheave installed in a machine room above the hoistway, and a main rope 52 is stretched over the hoisting machine 51. A passenger car 53 is suspended from one end of the main rope 52, and a counterweight 54 is suspended from the other end of the main rope 52. Reference numeral 55 denotes an elevator control device that controls operation of the car 53.

  The elevator control device 55 registers a call by operating the hall call button 56 installed at the hall of each floor or by operating the car call button 57 for designating the destination floor from the operation panel in the car 53, and then registers the call to the registered call. Based on this, a control command such as an operation command indicating the driving direction and a speed command is sent to the motor control device 58, and the hoist 51 is driven to rotate. The rotational force of the electric motor constituting the hoisting machine 51 is transmitted to the main sheave, and the car 53 is moved up and down using the frictional force between the main sheave and the main rope 52. These series of components 51 to 58 constitute a car operation control system.

  A floor selector 62 having a tape wheel 61 is installed in the machine room above the hoistway. As will be described later, the floor selector 62 has a function of extracting a signal relating to mechanical car position control of the old elevator system. A tape tension sheave 63 is disposed at the lower part of the hoistway just below the tape wheel 61 installed in the floor selector 62. A tape 64 such as a metal plate is stretched between the tape wheel 61 and the tape tension sheave 63, and both ends of the tape 64 are attached to the upper and lower portions of the car 53. As shown in FIG. 4A, protrusions 61a,... Protrude from the circumferential surface of the tape wheel 61 with a predetermined interval, and a gear 61b is attached to the tape wheel 61. Further, as shown in FIG. 4B, hooking holes 64a,... For engaging with protrusions 61a,.

  Further, the floor selector 62 has a car position detection arm having a tape wheel 61 and an energizing brush that meshes with the gear 61b of the rotation shaft of the tape wheel 61 to convert the rotary motion into a linear motion in the vertical direction. A movable table (not shown, hereinafter referred to as a synchronization table) and each floor terminal (not shown) arranged at a predetermined interval corresponding to the floor of the stop floor in the vertical direction facing the car position detection arm of the synchronization table. ) And are provided. When the brush of the car position detection arm contacts each floor terminal, the floor selector 62 sends a car synchronization position signal (hereinafter referred to as a car position signal) indicating the car position of the car 53 from the floor terminal. It has a function of sending to the control device 55. In other words, the floor selector 62 uses the mechanical scale operation mechanism such as the gear 61b and the car position detection arm described above in conjunction with the raising / lowering operation of the car 53 to rotate the tape wheel 61 forward and backward. Thus, a car position signal accompanying the raising / lowering operation of the car 53 is taken out and sent to the elevator controller 55. 65 is a shielding plate set within a certain distance from each floor in the hoistway, and 66 is a limit switch attached to the car 53 side. The limit switch 66 is formed in, for example, a U-shaped section, and sends a light-shielding signal when the shielding plate 65 passes through the U-shaped section to the elevator control device 55 so that a car stop command can be generated. These series of components 61 to 66 constitute a car position control system.

  Further, the synchronization table of the floor selector 62 moves forward in the car traveling direction when going from each floor to the call registration floor, and advances in advance in synchronization with the car 53 by a decelerable distance (not shown). Is installed. A car call detection arm (not shown) having an energizing brush also on the forward moving table, a landing rise call detection arm (not shown), a landing drop call detection arm (not shown), and each detection arm Each floor terminal (not shown) which is arranged at a predetermined interval corresponding to the floor of the stop floor in the vertical direction facing each other is provided.

  In each of the terminal blocks for car call detection, landing rise call, and landing drop call, the terminal block 56 or the car call button 57 is registered, and the terminal block is energized. A detection signal in which one of the arms is energized is sent to the elevator control device 55 so that a deceleration command can be generated, and the corresponding call is deleted.

  Further, the forward moving table receives a deceleration command from the elevator control device 55 and operates by the movement of the locked forward moving table and the car by locking the forward moving table to the lock base provided in the same manner as the terminal block. A value proportional to the distance from the synchronization table is calculated as the deceleration command value in the speed command value.

  65 is a shielding plate set within a certain distance from each floor in the hoistway, and 66 is a limit switch attached to the car 53 side. The limit switch 66 is formed, for example, in a U-shaped section, and sends a light-shielding signal when the shielding plate 65 passes through the U-shaped part to the elevator control device 55 to be used as a car position signal of the floor selector 62. On the other hand, a more precise car stop command is generated. These series of components 61 to 66 constitute a car position control system.

  Accordingly, the elevator control device 55 of such an elevator system performs call registration when the hall call button 56 or the car call button 57 is operated, and then the registered call and the car position signal of the floor selector 62. The speed command is calculated based on the operation command indicating the upper or lower direction based on the above and the registered call and signal on the car position, and the control command such as the operation command and the speed command is output to the motor control device 58. Send it out. The motor control device 58 rotates the electric motor of the hoisting machine 51 according to the control command, receives the rotation speed and torque feedback signals from the hoisting machine 51, and controls the electric motor of the hoisting machine 51 so as to become the speed command. Speed control.

  Next, the configuration related to the control operation of the elevator controller 55 and the floor selector 62 will be described with reference to FIG. The elevator controller 55 includes a call registration / deletion circuit 55a, a direction selection circuit 55b, an operation command circuit 55c, a first speed command value calculation circuit 55d that calculates speed command values for acceleration and low speed, and at the time of deceleration. A second speed command value calculation circuit 55e for calculating the speed command value and a speed selection circuit 55f are provided.

  On the other hand, the floor selector 62 has a synchronous position (car position signal) calculation unit 62a that acquires a car position signal by moving up and down in synchronization with the raising and lowering operation of the car 53, an operation command unit 62b, and a forward position calculation. A portion 62c is provided.

  The call registration / deletion circuit 55a registers a call associated with the operation of each call button 56, 57 and then sends the registered call to the direction selection circuit 55b. The direction selection circuit 55b determines the driving direction from the registered call and the car position signal output from the synchronous position calculator 62a of the floor selector 62, and sends it to the driving command circuit 55c. Here, the operation command circuit 55c sends an operation command to the first speed command value calculation circuit 55d, the speed selection circuit 55f, and the motor control device 58 based on the operation direction determined by the direction selection circuit 55b, and the operation is performed. The command is sent to the operation command unit 62b of the floor selector 62. The first speed command value calculation circuit 55d calculates a speed command value at the time of acceleration / constant speed based on a predetermined speed pattern and sends it to the speed selection circuit 55f. The speed selection circuit 55 f selects a speed command value at the time of acceleration / constant speed based on the operation command, and starts rotating the electric motor of the hoisting machine 51 via the motor control device 58.

  On the other hand, the operation command unit 62b of the floor selector 62 that receives the operation command from the operation command circuit 55c operates the synchronization position calculation unit 62a and the forward position calculation unit 62c based on the operation command. The synchronization position calculation unit 62a sends a car position signal to the direction selection circuit 55b in synchronization with the raising / lowering operation of the car 53 as described above. Further, the forward position calculation unit 62c moves the forward moving table forward in the car traveling direction by a distance corresponding to the deceleration distance at a high speed, and moves up and down in synchronization with the lifting speed of the car 53.

  In accordance with the traveling of the car 53, the call registration / deletion circuit 55a deletes the registered call and receives the call registration in response to the advance position calculation unit 62c detecting that the forward moving platform is locked. An erase signal is sent to the operation command circuit 55c via the direction selection circuit 55b. The operation command circuit 55c sends a deceleration command for selecting the speed command of the second speed command value calculation circuit 55e to the speed selection circuit 55f based on the call registration deletion signal. Further, when the operation command circuit 55c sends a stop command to the operation command unit 62b of the floor selector 62, the operation command unit 62b issues a stop command for the advance position signal to the advance position calculation unit 62c. Here, the forward movement position calculation unit 62c sends a signal proportional to the distance that the forward movement base contracts after the forward movement base is locked to the lock base to the second speed command value calculation circuit 55e. Therefore, the second speed command value calculation circuit 55e calculates a deceleration command value from a signal proportional to the distance, and sends it to the motor control device 58 through the speed selection circuit 55f. The motor controller 58 decelerates and rotates the electric motor of the hoisting machine 51 according to the deceleration command value.

  Thereafter, the direction selection circuit 55b of the elevator controller 55 receives the car position signal arriving at the call registration floor from the synchronous position calculation unit 62a of the floor selector 62, and the car is within a certain distance range from the limit switch 66. When a signal indicating that the motor has entered is received, a stop command is sent to the motor controller 55 and the operation command unit 62b of the floor selector 62 via the operation command circuit 55c, and the motor and the synchronous position of the hoisting machine 51 are transmitted. The calculation unit 62a is stopped.

In addition, as a prior document, it mentions later from the point which makes it easy to understand the process which implement | achieves this invention apparatus (patent document 1).
JP-A-2-70683 (see FIG. 1).

  Therefore, in the old elevator system as described above, the floor selector 62 is mainly composed of mechanical operation products as described above, and operates on a daily basis along with the raising / lowering operation of the car 53 over a long period of time. As a result, some operating products have a short life and are scaled operation mechanisms with mechanical movements, so mechanical operating products are severely damaged, worn, etc., and are likely to be displaced. Therefore, it is necessary to frequently perform maintenance inspections and replacement of operating equipment. Furthermore, since it is necessary to operate accurately as part of the control, a considerably high level of adjustment skill is required at the time of maintenance inspection and replacement work of operating equipment.

  Therefore, in order to relieve the necessity of the short life and high adjustment skills of the operation equipment, it is possible to digitize it as an alternative to the old elevator system, in particular, the product related to the car position detection such as the floor selector 62. desirable.

  Further, even when the substitute for the product related to the car position detection is digitized, the computerized substitute is simulated and comprehensively verified, and whether or not the linkage with each component, for example, the elevator controller 55 is appropriately performed. A simulated elevator testing device is required to verify the above. As the elevator test apparatus, in addition to the elevator car 3 on the hoistway side and the limit switch 66, a hoisting machine 51 on the machine room side, an elevator control apparatus 55, and a motor control apparatus 58 are also required.

  In general, the hoistway side equipment can be used by replacing it with a general new product. However, as shown in FIG. 3, the position of a car that is a part of an old elevator control product, such as a mechanical floor selector 62, is used. When comprehensively verifying substitute products by computerization of products related to control, it is necessary to newly prepare an old product such as the old elevator control device 5 and the like, and a test apparatus for verifying the computerized substitute product becomes excessive. Further, even when the old elevator control device 5 is prepared, an elevator control device as a test device cannot be manufactured due to, for example, discontinuation of manufacture of electronic components used in the control device, and comprehensive verification of an electronic substitute cannot be performed. In elevator control, in particular, car position control is an important factor, and comprehensive verification of alternatives by computerization is indispensable.

  By the way, there has already been proposed a simulated elevator test apparatus (Patent Document 1 described above). This elevator test device connects a maintenance device such as a personal computer to the elevator control device and the group management control device, generates a simulation test command from operation command information from the maintenance device, and executes a simulation test operation of the car. Then, actual measurement information corresponding to the control information of the car during the simulation test operation is actually measured based on selection information fetched from an external device such as a hall call button of each floor hall. Then, the control information and the actual measurement information are compared, and the presence or absence of abnormality such as not responding to the car call or not reaching the assumed prediction accuracy is diagnosed.

  However, the elevator test equipment does not renew the old elevator system, and when replacing a product related to mechanical position control with an electronic substitute, the electronic substitute replaces the old configuration of the remaining old elevator system. Nor does it verify that proper collaboration can be achieved with the product.

  The present invention has been made in view of the circumstances as described above, and in developing an electronic substitute for a mechanical old product that takes out a car position signal of a car, it does not require excessive facilities and is closer to a real machine. The purpose of the present invention is to provide an elevator testing apparatus that verifies an electronic substitute and enables the development of an electronic substitute.

  It is another object of the present invention to provide an elevator testing apparatus that is capable of easily adding test items and is highly flexible.

In order to solve the above-mentioned problems, the present invention replaces a mechanical product that takes out a signal related to a car position synchronized with the raising / lowering operation of a car of an elevator system with an electronic substitute (hereinafter referred to as a device under test), In an elevator test apparatus for verifying the device under test,
Register a call input device having at least a hall call input unit for inputting a hall call signal and a car call input unit for inputting a car call signal for designating a destination floor, and a call signal inputted from the call input device, and registering the registration. A sequence control device that determines and outputs an operation command and a speed command at a predetermined speed under the call, and a motor to drive the elevator in accordance with the operation command and speed command determined by the sequence control device, thereby raising and lowering the car A motor control device for simulating and controlling
A rotational speed signal attached to the rotating shaft of the electric motor and synchronized with the car position of the car is taken out and sent to the device under test and the sequence control device to generate a car position signal for the device under test. In addition, the elevator test apparatus is provided with position detection means for generating a car position signal when the sequence control apparatus enters the call registration floor within a predetermined distance range.

  The sequence control device generates and outputs an operation command or a deceleration command based on the car position signal sent from the device under test and the deletion of the registered call or registered call. The advance position signal that precedes the test object according to the deceleration distance in the traveling direction of the car is operated based on the test object, and the advance position signal is output to the test object under the deceleration command. The operation command means that stops the operation of the motor and outputs a signal proportional to the distance to the call registration floor, and the acceleration / rated speed based on a predetermined speed pattern based on the operation command output from the operation command means A first speed command value calculating means for calculating a command value and a second speed for calculating a speed command value for deceleration based on a signal output from the DUT and proportional to a distance to the call registration floor finger Command value calculating means, and using the acceleration / rated speed command value of the first speed command value calculating means based on the operation command output from the operation command means, the motor is accelerated / constantly rotated. The motor is decelerated and rotated using the deceleration command value of the second speed command value calculation means based on the deceleration command output from the operation command means.

  With the above configuration, the sequence control device can verify whether the digitized elevator position control device properly outputs a signal related to the car position.

  The position detecting means may be one in which one position sensor or two position sensors are attached to the rotating shaft of the electric motor. In the case of one position sensor, the rotation speed signal of the motor obtained from the position sensor is sent to the operation command means and the device under test. In the case of two position sensors, the operation command is used to generate a deceleration command when the car has entered a predetermined distance range on the call registration floor based on the rotation speed signal of the motor obtained from one position sensor. The motor speed signal obtained from the other position sensor is sent to the device under test to generate the car position signal. In particular, when a signal related to the car position is generated by sharing one position sensor, the position accuracy can be improved because the signals are integrated.

  Furthermore, if the screen input device provided with the touch panel is provided as the call input device and a control signal other than the call signal is input to the sequence control device, a desired verification item can be added.

  Further, instead of the motor control device, the electric motor and the position detection means, a pulse transmission device is provided on the output side of the sequence control device, and the operation of the position detection means is simulated by the sequence control device. By controlling the apparatus to output the same transmission pulse as the rotation speed signal output from the position detection means from the pulse transmission apparatus, the number of simulated components is reduced, and the test apparatus is reduced in size and cost. It is feasible.

  According to the present invention, when developing an elevator position control device that is an electronic substitute for a mechanical old product that takes out a car position signal of a car, the elevator position control is performed in a state closer to an actual machine without using excessive facilities. It is possible to provide an elevator test apparatus that can verify the apparatus and can easily develop a highly accurate electronic substitute.

  In addition, the present invention can provide an elevator testing apparatus that is capable of easily adding verification items and is rich in flexibility.

  In addition, the present invention can provide a flexible elevator test apparatus in which test items can be easily added by using a touch panel as an apparatus for test control input such as call input.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an embodiment of an elevator test apparatus according to the present invention. In the figure, reference numeral 10 denotes an elevator position control device. The elevator position control device 10 corresponds to, for example, an electronic substitute for the floor selector 62, which is a product that extracts a signal related to the car position. Accordingly, the elevator position control device 10 is a device to be tested.

  The elevator control device 20 is an elevator test device that is a main part of the present invention for verifying whether or not the elevator position control device (an electronic substitute for the floor selector 62) operates properly. The elevator test apparatus 20 includes a call input device 21, a sequence control device 22, a motor control device 58a, an electric motor 51a that constitutes a hoisting machine that simulates a lifting operation of a car, and first and second position sensors 23a and 23b. Consists of.

  The call input device 21 is connected to the sequence control device 22 and has a function of inputting a signal corresponding to a call by operating a hall call button or a car call button on each floor to the sequence control device 22.

  The sequence control device 22 is connected to the call input device 21, the elevator position control device 10, and the motor control device 58a. The sequence control device 22 determines the driving direction based on the hall call signal or the car call signal input from the call input device 21 and the car position signal output from the elevator position control device 10 in synchronization with the raising / lowering operation of the car. Then, an operation command based on the determined operation direction is sent to the motor control device 58a and the elevator position control device 10, and a speed command is sent to the motor control device 58a to rotate the electric motor 51a.

  The first and second position sensors 23a and 23b are attached to the rotation shaft of the electric motor 51a, detect rotation speed signals due to forward / reverse operation of the electric motor 51a according to the operation command, and sequence the respective rotation speed signals. It is sent to the control device 22 and the elevator position control device 10. That is, the first position sensor 23a takes out a rotation speed signal for generating a deceleration command when the car has entered the predetermined distance range on the call registration floor and sends it to the sequence control device 22. The second position sensor 23 b takes out a rotation speed signal for generating a car position signal and sends it to the elevator position control device 10.

  The sequence controller 22 detects that the car has entered the predetermined distance range on the registered floor from the rotation number signal of the first position sensor 23a, and generates a deceleration command for decelerating the electric motor 51a. The elevator position control device 10 generates a car position signal from the rotation speed signal of the electric motor 51a that is synchronized with the raising / lowering operation of the car, and has the role of functioning as a floor selector described above.

FIG. 2 is a diagram showing a configuration related to control operations of the call input device 21, the sequence control device 22, and the elevator position control device 10.
The call input device 21 generates a hall call input unit 21a that generates a hall call signal corresponding to the operation of the hall call button on each floor and a car call signal corresponding to the operation of the car call button specified on the destination floor of the in-car operation panel. A generated car call input unit 21b is provided. The hall call input unit 21a and the car call input unit 21b do not need to be hardware switch parts, and may be configured by software switches.

  The sequence control device 22 may be configured to realize a circuit configuration corresponding to an old elevator control device or the like using existing electronic components, or to execute predetermined processing according to a software sequence program. The sequence control device 22 includes call registration / deletion means 22a for deleting the registered call and the registered call of the hall call signal and the car call signal from the call input units 21a and 21b, direction selection means 22b, and operation command means. 22c, first speed command value calculating means 22d, second speed command value calculating means 22e, and speed selecting means 22f.

  The direction selection means 22b determines the driving direction based on the call registered by the call registration / deletion means 22a and the car position signal of the elevator position control device 10. The operation command unit 22c sends the operation command to the first speed command value calculation unit 22d, the speed selection unit 22f, and the motor control device 58a according to the operation direction determined by the direction selection unit 22b. Further, the operation command means 22 c sends an operation command to the elevator position control device 10. Here, the first speed command value calculation means 22d calculates an acceleration / rated speed command value based on a predetermined speed pattern, and supplies it to the motor control device 58a via the speed selection means 22f. The motor control device 58 starts rotation of the electric motor 51a according to the acceleration / rated speed command value, and executes acceleration and rated operation.

  On the other hand, the elevator position control device 10 has a functional configuration equivalent to that of the floor selector 62 in terms of function, and is based on a rotational speed signal that is a signal that simulates the elevator lifting / lowering operation from the position sensor 23b. The car position signal acquisition unit 10a that acquires a car position signal synchronized with the car position, an operation command unit 10b, and a forward position signal acquisition unit 10c. When the operation command unit 12b receives the operation command from the operation command means 22c of the sequence control device 22, the operation command unit 12b operates the car position signal acquisition unit 10a and the forward position signal acquisition unit 10c, and causes the forward position signal acquisition unit 10c to decelerate the car. A distance signal suitable for Further, the forward position signal acquisition unit 10c sends to the call registration / erase means 22a a forward position signal indicating that the car registration signal has approached a predetermined distance from the car position signal obtained from the car position signal acquisition unit 10a. As a result, the operation command means 22c of the sequence control device 22 receives the forward position signal and the next call and erases the registered call after the call registration / erasure means 22a receives the call erase signal from the call registration / erasure means 22a. Is received, a stop command is sent to the operation unit 10b of the elevator position control device 10, and a signal proportional to the distance from the telegram position signal acquisition unit 10c to the call registration floor is sent to the second speed command value calculation means 22e. Send it out. Here, the second speed command value calculating means 22e calculates a speed command value at the time of deceleration according to a signal proportional to the distance to the call registration floor, and the electric motor via the speed selecting means 22f and the motor control device 58a. 51a is decelerated and rotated.

  Further, a car position signal indicating that the car has entered a certain distance range from the speed signal including the rotation direction detected by the first position sensor 23a to the call registration floor is output to the sequence control device 22. A car position signal acquisition unit 22g and a hoistway switch circuit 22h that operates with a signal output from the car position signal acquisition unit 22g and notifies the operation command means 22c and the elevator position control device 10 are provided. The operation command means 22c receives a signal arriving at the registration floor from the elevator position control device 10 via the direction selection means 22b, and notifies the elevator car switch circuit 22h that the car has entered a certain distance range. When received, a stop command is sent to the motor control device 58a and the elevator position control device 10, and control is performed to stop the electric motor 51a and the elevator position control device 10.

Next, the example which verifies the elevator position control apparatus 20 using the above elevator test apparatuses is demonstrated.
When a floor-identifiable call signal is input from the hall call input unit 21a or the car call input unit 21b, the call registration / deletion means 22a of the sequence control device 22 registers the call signal in a memory (not shown), while A call signal is sent to the direction selection means 22b. The direction selection means 22b determines the operation direction of the call registration floor from the registered call and the car position signal output from the car position signal acquisition unit 10b of the elevator position control device 10, and sends it to the operation command means 22c. Here, the driving command means 22c gives a driving command based on the driving direction determined by the direction selecting means 22b, in addition to the first speed command value calculating means 22d and the speed selecting means 22f in its own apparatus, as well as the motor control device 58a. And sent to the operation command unit 10b of the elevator position control device 10.

  Here, the first speed command value calculation means 22d calculates a speed command value at the time of acceleration / constant speed based on a predetermined speed pattern and sends it to the speed selection means 22f. The speed selection means 22f selects a speed command value at the time of acceleration / constant speed based on the operation command, and starts rotating the motor 51a of the hoisting machine via the motor control device 58a.

  On the other hand, the operation command unit 10b of the elevator position control apparatus 10 operates the car position signal acquisition unit 10a and the forward position signal acquisition unit 10c when receiving the operation command from the operation command means 22c. The forward position signal acquisition unit 10c holds the forward position signal that precedes the traveling direction of the car by an amount corresponding to the deceleration distance.

  Thereafter, with the rotational operation of the electric motor 51a, the forward position signal acquisition unit 10c determines from the car position signal from the car position signal acquisition unit 10b that the car has reached a distance corresponding to the deceleration distance from the registered floor. Then, a forward position signal is sent to the call registration / deletion means 22a. The call registration / deletion unit 22a receives the advance position signal from the advance position signal acquisition unit 10c and receives the next call from the call input device 21, and deletes the registered call and sends the call registration delete signal to the direction. The data is sent to the operation command means 22c via the selection means 22b.

  The operation command means 22c sends a deceleration command for selecting the speed command of the second speed command value calculation means 22e to the speed selection means 22f based on the call registration deletion signal. The operation command means 22 c also sends a stop command to the operation command unit 10 b of the elevator position control device 10. As a result, the operation command unit 10b issues a stop command for the forward position signal to the forward position signal acquisition unit 10c. Here, the forward position signal acquisition unit 10c sends a signal proportional to the distance approaching the call registration floor to the second speed command value calculation means 22e. Therefore, the second speed command value calculating means 22e calculates a deceleration command value from a signal proportional to the distance, and sends it to the motor control device 58a through the speed selecting means 22f. The motor control device 58a decelerates and rotates the electric motor 51a according to the deceleration command value.

  Subsequently, the direction selection means 22b of the sequence control device 22 receives the car position signal arriving at the call registration floor from the car position signal acquisition unit 10a of the elevator position control device 10, and is constant from the hoistway switch circuit 22h to the call registration floor. When a signal indicating that the distance is within the range is received, a stop command is sent to the motor controller 58a and the operation command unit 10b of the elevator position controller 10 via the operation command means 22c, and the motor 51a and the synchronous position signal are transmitted. The operation of the acquisition unit 10c is stopped.

  Therefore, according to the embodiment as described above, based on the call signal input from the call input device 21, the electric motor 51a that simulates the raising / lowering operation of the car is rotated based on the predetermined operation command and speed command. Then, the rotational speed signal including the rotational direction of the electric motor 51a is taken out by the position sensors 23a and 23b, and the elevator position control device 10 which is a floor selector for generating a car position signal and a signal for generating a stop command are sequenced. Since the feedback is made to the control device 22, a series of operations of the elevator position control device 10 which is an electronic substitute can be accurately verified. Moreover, since the elevator test apparatus 20 can be realized by using existing electronic components, it is not necessary to use most of the facilities of the old elevator system, the entire facility can be realized in a compact manner, and enlargement of the facility is avoided. Is possible.

  Further, the sequence control device 22 can realize a process required by the CPU using a software sequence program or the like, and can be realized more compactly.

  In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, various deformation | transformation can be implemented.

(1) In the above embodiment, the two position sensors 23a and 23b are attached to the rotating shaft of the electric motor 51a that constitutes a part of the hoisting machine. For example, one position sensor is attached, and this position sensor can be used. The configuration may be such that the rotation number signal is guided to the car position signal acquisition unit 22g of the sequence control device 22 and the car position signal acquisition unit 10a of the elevator position control device 10.

  When one position sensor is used in this way, since there is only one rotation speed signal source obtained from the same electric motor 51a, variations in detection accuracy of the two position sensors 23a and 23b are eliminated, and position control is further performed. Can be improved, and the cost can be reduced.

(2) The hall call input unit 21a and the car call input unit 21b of the call input device 21 in the above embodiment do not have to be hardware switches as described above, and can be realized using software switches. Needless to say, if a screen input device with a touch panel is provided as the call input device 21, for example, an elevator such as changing the speed pattern, changing the type of the control panel, or changing the adjacent distance of each floor, etc. Control test items can be added or changed. For example, for a speed pattern change, if a touch panel switch intended for speed change is touched, and desired speed pattern data is written in a memory (not shown) so as to overwrite the previously set speed pattern, the speed command value calculation means 22d Calculation is based on the changed speed pattern data. In addition, if the touch panel switch for speed change is touched, the signal of the touch position is introduced into the speed command value calculation means 23d and 23e, and the calculation parameter that can be changed at any time is changed, the speed pattern can be changed. Is possible. Furthermore, although the floor of the building is the 10th floor, it is possible to control the elevator car up and down by assuming the 15th floor for example.

(3) Further, in the above embodiment, the position sensors 23a and 23b are provided on the rotating shaft of the electric motor 51a. However, for example, a pulse transmission device is connected to the output side of the sequence control device 22, and the speed command of the sequence control device 22 is provided. If a signal proportional to the speed command value of the car is applied to the pulse transmission device from the value calculation means 22d and 22e, a pulse signal corresponding to the car position synchronized with the raising / lowering operation of the car is output from the pulse transmission device. Can do. Therefore, by providing a pulse transmission device in the sequence control device 22, the motor control device 58a, the electric motor 51a, and the position sensors 23a and 23b can be deleted, and the required verification of the elevator position control device 10 can be performed while downsizing the test equipment. It can be done easily.
