Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to an elevator deceleration position correction device, and more particularly, to an elevator deceleration position correction device that can easily correct an elevator travel command turn. The present invention relates to a position correction device.

(Prior Art) As buildings become taller, the distances traveled by elevators used in these buildings become longer and their speeds also become faster. This type of elevator is required to have excellent ride comfort and accurate landing precision at each floor. There is a need for smooth running with no waste.

FIG. 8 shows typical travel command patterns of commonly used elevators, where travel command pattern A is for traveling on long floors, and travel command pattern B is for short floors. This is the case when driving. That is, if the vertical axis is speed and the horizontal axis is time, in travel command pattern A, the speed is sequentially accelerated from the departure floor (part a), then reaches a constant high speed at intermediate floors (part b), and then reaches the arrival floor. When it approaches the floor, it is decelerated (section C) and stopped at the arrival floor (section d). On the other hand, in travel command pattern B, acceleration is performed from the departure floor (part a), there is no constant high speed section, and the acceleration is shifted to deceleration on the arrival floor from the middle of acceleration (part C). It is stopped at (d part). In this case, a travel command pattern such as travel command pattern B in which the floor distance from the departure floor to the arrival floor is short and only includes acceleration and deceleration is called a short run characteristic.
In particular, the one with the greatest acceleration and deceleration is called the maximum short run characteristic.

Further, in this characteristic, the acceleration constant speed characteristic part from part a to b part is called a time space pattern, the deceleration characteristic part in part C is called a distance space pattern, and the stop part in part d is called a rare bed pattern.

By the way, as buildings get taller, the speed of elevators becomes faster, but since the floors used vary from long floors to short floors, there are more cases where elevators are run using travel command pattern B. There is.

Even under these conditions, elevators are required to have excellent ride comfort and accurate landing on each floor, so the following method is used as a basic running command.

(1) From accelerated travel on the departure floor to high-speed constant speed travel, that is, in a time-space pattern, a constant speed command is sent regardless of travel distance.

(2) In the case of high-speed constant-speed running or deceleration running from the middle of acceleration to the arrival floor, that is, distance space pattern, a speed command is sent according to the remaining distance.

For example, in order to cause the elevator to travel at a constant deceleration β (m/S2) for the remaining distance jfis (m), a speed command Vs as shown in the following formula is sent.

Vs-J2βS-(1)(3), from near the arrival floor until the elevator stops, that is, in the young floor pattern, an accurate position signal is sent, and this position signal causes the elevator to stop at the regular landing position.

These commands allow the time space pattern, distance space pattern, and landing pattern to be smoothly transitioned.

In addition, in order for the elevator to run comfortably, acceleration,
During deceleration, the speed change rate (hereinafter referred to as jerk) is set so that it does not become too large. This jerk also occurs in the area of the landing pattern that causes the elevator to come to a quiet stop. Therefore, in an actual elevator, the final position of the landing pattern is a distance # a little before the stop position! (This distance is called ΔS). Expressing this in the formula,
Vs-42β(S18S)-(2). ΔS in equation (2) is called a correction distance, and is determined based on landing pattern characteristics, gain, etc.

At present, most control devices that issue such travel commands use microcombiners, and the elevator position, speed, etc. are calculated as digital quantities. Further, this microcomputer is provided with a memory section in which all travel command patterns of the elevator from each departure floor to the arrival floor are stored, and the elevator is run according to this travel command pattern. There is.

(Problems to be Solved by the Invention) However, when traveling in an elevator using these travel command patterns, there is a control delay in the control system from the travel command until the electric motor etc. are operated. In particular, compared to general industrial elevators, passenger elevators are set to have a relatively slow response in order to improve ride comfort, so the delay in the control system is large. Therefore, the transition from the distance-based pattern to the landing pattern is not performed smoothly.

To explain this using Fig. 9, the transition from the ideal distance pace pattern (section C) to the landing pattern (section d) is as shown in Fig. 9(a), but in reality it is as shown in Fig. 9(a). It is said that the switching of the valley floor pattern (d part) is delayed as shown in b), or the landing pattern (d part) changes quickly as shown in Figure 9 (c), causing a shock to the passenger upon landing. There was a problem.

In order to solve this problem, there is a method in which a microcomputer calculates the total travel distance from the departure position to the arrival position of the elevator, and selects the optimal travel command pattern required by the elevator from that distance. However, even if this method is adopted, there is a problem in that the transition from the distance space pattern to the landing pattern cannot be smoothly performed due to elevator control delays, the condition of the building in which the elevator is installed, etc.

In order to solve these problems, when installing an elevator in a building, the distance and space pattern depending on the building,
Adjustments and corrections are made to obtain the optimum implantation pattern. However, due to reasons such as the long distance traveled, the large number of floors, uneven distance between floors, and fast speeds, the number of adjustments and corrections required is large and the work becomes complicated. There were some problems.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an elevator deceleration position correction device that facilitates on-site adjustment and correction work.

[Structure of the invention]

(Means for Solving the Problem) The present invention causes an elevator installed in a building to run according to a travel command pattern, and decelerates the elevator by adjusting and correcting the travel command pattern of the elevator to match the installation state of the building. In the position correction device, there is an adjustment travel command section that selects a travel command pattern for the elevator to be run and issues an adjusted travel command, and a travel control that receives the adjustment travel command from the adjustment travel command section and causes the elevator to travel according to the selected travel command pattern. a travel pattern detection unit that detects a travel pattern of an elevator caused to run by the travel control unit; and a correction value calculation unit that calculates a correction value for the elevator that is suitable for the building from the travel command pattern and the travel pattern. A correction data storage section is provided which records the calculation output of the correction value calculation section and sends this correction output to the travel 19 control section to which the travel command pattern is commanded.

(Function) When an elevator installed in a building receives an adjustment travel command, the floor on which the elevator will travel is determined.

With this determination of the floor to be traveled, a travel command pattern suitable for the floor to be traveled is selected, and the elevator is run according to this travel command pattern. This elevator running pattern is detected by a detector, and this running pattern is compared with the running command pattern to calculate a correction value suitable for the building. This calculation output is recorded and sent to the elevator together with the travel command pattern, and is used as the elevator travel command pattern.

(Embodiment) An embodiment of the deceleration position correction device for an elevator according to the present invention will be described below with reference to the drawings.

FIG. 1 schematically shows the main parts of the deceleration position correction device of the present invention.
A sheave 10 that is reversibly operated is installed.

A lobe 11 is hung on this sheave 10, an elevator cage 12 is attached to one end of the lobe 11, and a counterweight 1 is attached to the other end of the lobe 11.
3 is attached, and by forward and reverse rotation of the sheave 10, the elevator cage 12 is moved to each floor 14a, 14b, 14c, etc. of the building.
You can run between them.

A pulse generator 15 and a speed detector 16 are attached to the rotating shaft 10a of the sheave 10. This pulse generator 15 generates a pulse signal in accordance with the rotation of the sheave 10, and this pulse signal is used as a position detection signal fd of the sheave 10, that is, the elevator car 12. sent to. Also, the speed detector 16 emits 7N! depending on the rotational speed of the sheave 10! Electric power is generated, and this generated power is sent to the traveling control section 18 as the traveling speed signal fv of the elevator car 12.
sent to.

Further, the elevator car 11 is provided with a position detection switch 19. This position detection switch 19 switches to the position of each floor 14a, 14b, 14c, etc. when the elevator car 11 reaches the landing area of each floor 14a, 14b, 14c, etc., for example, 200l above and below the landing position. A corresponding position detection signal fn is generated, and this position detection signal fn is sent to the speed error detection section 20 of the elevator control device 17.

The elevator control device 17 includes a pulse generator 1.
A travel control section 18 is provided which receives the position detection signal fd of the vehicle 5 and the travel speed signal fv of the speed detector 16. The traveling control section 18 includes a converter that converts the traveling speed signal fv into a digital signal, and a memory section for storing various data such as the height of the building in which the elevator is installed, the number of floors, the distance between each floor, and the speed of the elevator. (none of which are shown).

Output signals 18a such as the position detection signal fd of this travel control section 18 are sent to a speed error detection section 20. The speed error detection section 20 is provided with an arithmetic controller for calculating position and speed, and also receives the position detection signal fn from the position detection switch 19. When this speed error detection section 20 receives the output signal 18a of the traveling control section 18 and the position detection signal fn, these signals are processed,
The output signal 20a is sent to the correction value calculation section 21. In this correction value calculating section 21, a correction value for the elevator is calculated based on the position and speed of the elevator, that is, an error between a travel pattern and a travel command pattern (described later) using the output signal 20a, and the correction value is used in a correction data table. The correction data is sent to the correction data storage unit 22 and recorded therein.

The correction data storage section 22 sends this correction value 22a to the travel control section 18 and also to the adjustment travel command section 23 where it is used as a monitoring signal 22b.

The 2-way running command unit 23 stores a plurality of high-floor running command patterns and low-floor running command patterns for high-rise elevators, and when it receives a correction command from the correction command device 24, it adapts it to the floor on which it is going to run. The most suitable driving command pattern can be selected.

Note that 25 is a correction data calculation unit which selectively takes out the correction data stored in the correction data storage unit 22;
The correction data is divided and calculated, and the calculated values of each divided portion are returned to the correction data storage section 22.

Next, the operation of the elevator deceleration position correcting device configured as described above will be explained with reference to a flowchart.

When an elevator is installed in a building, a correction command 24a is sent from the correction command device 24 to the correction value calculation section 21, the adjusted travel command section 23, and the correction data calculation section 25. When the correction value calculation unit 21 and the correction data calculation unit 24 receive the correction command 24a, they are brought into operation.

When the adjusted travel command section 23 receives the correction command signal 24a as shown in the flowchart of FIG. 2 (Sll), the operation of the adjusted travel command section 23 is started. At this time, the correction monitoring signal 22b is sent from the correction data storage section 22 to the adjustment traveling command section 23, and the adjustment correction status of the elevator is confirmed (S12). Elevator: A! If M correction is not done, yJ! Various data from the travel control section 18 are sent to the J adjustment travel command section 23, and are written into the adjustment travel command section 23 as data necessary for adjustment correction (5 1 3). Based on these data, the adjusted travel command section 23 selects the nth floor (for example, the 5th floor) that will cause the maximum short run of the elevator (S14), and determines the travel command pattern that will result in this maximum short run. Once this travel command pattern is determined, the travel command pattern 23a is sent from the adjustment travel command section 23 to the travel control section 18, and an adjustment operation is started (S15).

When the travel control unit 18 receives this travel command pattern 23a, the elevator control unit is operated, the sheave 10 is rotated, and the elevator car 12 causes the maximum short run.
The vehicle travels between floors according to a command pattern from an upper floor to a lower floor or from a lower floor to an upper floor. At this time, the sheave 10 is transmitted from the pulse generator 15 and the speed detector 16.
A position signal fd and a generated power signal fv are generated along with the rotation of
Sent to 8th. The travel control section 18 converts the generated power signal fv into a digital signal, and sends this digital signal, the position signal fd which is a pulse signal, and the output signal 18a of the travel command pattern to the speed error detection section 20.

As shown in the flowchart of FIG. 3, the speed error detection unit 20 receives the output tS 18a and compares the running conditions such as speed and position with the running command pattern to check whether predetermined values are maintained ( S21). Further, when the elevator edge comes to a position 200 mm from the upper and lower stopping floors, a position signal is generated from the position detection switch 19 (S 2 2). This position signal is detected as a travel pattern of the elevator relative to the building.

When this position signal is sent to the speed error detection section 20, the speed error detection section 20 generates a speed signal of 200 mm of the stop floor (S23). The elevator speed signal based on this speed signal and the travel command pattern is a
"WL" and its error is calculated (S24). The result of the calculation is taken out as the error output signal 20a and sent to the correction value calculation section 21 (S25).

As shown in the flowchart of FIG. 4, this correction value calculation unit 21 receives a correction command from the correction command device 24 (S
31), the speed error output signal 20a is manually input (S
3 2). If this speed error output signal 20a has no error between the travel command pattern signal and the position detection signal (333)
The signal is directly sent to the correction data storage section 22 as the optimum travel command pattern for the building in which the elevator is to be run, and is recorded therein (S34). Further, when the speed error output signal 20a is larger than a predetermined value (S33), the speed error output signal 20a is subjected to correction calculation processing (S35), and the correction calculation processing data, that is, the error between the travel command pattern and the travel pattern is The adjustment correction signal 21a is sent to the correction data storage section 22, and this adjustment correction signal is recorded (S
36).

These 5! The J alignment correction signal 21a is stored in the correction data storage section 22.
When received, a correction signal 22a is sent to the travel control section 18, and a monitoring signal 22b thereof is sent to the adjustment travel command section 23. When the adjusted travel command unit 23 receives the monitoring signal 22b, the adjusted travel command unit 23 determines whether the signal requires adjustment correction or not, and if it is determined that correction is required,
The travel command pattern 23a is sent again from the adjustment travel command unit 23 to the travel control unit 18 as a correction command (S 1 1
).

The travel control section 18 receives the correction signal 22a and the travel command pattern 23a, and repeats the travel control based on these signals (S15).

In this way, the elevator travels based on the travel command pattern and the adjustment correction signal until it matches the signal received from the elevator travel pattern, that is, until the signal becomes zero. When this value becomes zero, this correction value d (see FIG. 5) is taken as the correction data for the nth floor that causes the maximum short run. This correction data d is stored in the correction end section 30 of the correction data storage section 22,
It is recorded in the up section 31 or the dn section 32 (see Fig. 5(a)).
) (b) (c)), the correction of the n floors that cause the maximum short run is completed.

After this 2ffi correction is completed, the adjustment travel command section 23 calculates the n-
The first floor (for example, the fourth floor) is selected.

A traveling command pattern suitable for the (n-1) floor is selected by the aforementioned method, which is t'P for this selection, and adjustment and correction of this traveling command pattern is performed. This adjustment correction is performed by replacing the value of the maximum short run n floor in the flowchart of FIG. Processed (S 1 6)
. In this way, all adjustments and corrections are made for each floor where a short run occurs, and the adjustment operation is completed (S 1 7).

By the above method, from floor n to floor n-1, n -2
Adjustment and correction of short runs on floors, floors n-3, etc. are performed, and correction values d (l
o), dl (1 1) and d2 (12)- can be obtained (see FIG. 5), and these adjustment correction values are recorded in the correction data storage section 22.

In addition, since the landing pattern is important in selecting the running command pattern for long floors, it is possible to directly select the optimal one by appropriately combining the characteristics of each short run selected using the above method. can.

When the elevator is actually run in a building in this way, the correction value and the run command pattern are sent to the run control section 18, and the elevator is run based on these values. Therefore, the elevator runs with running characteristics that suit the building, and does not cause discomfort to passengers.

FIG. 6 shows a part of the characteristics shown in FIG. 5, for example, the correction value d is further divided into six such as di-1, d1-2, etc., and the respective distances Mdl-1, d1-2, etc. Corrects the adjustment correction based on the travel command pattern in ..., data calculation unit 25
The detailed characteristics were determined by calculation. In this way, an accurate travel pattern can be selected for each floor, especially near the stop.

〔Effect of the invention〕

The elevator installed in the building is run along the travel command pattern, the travel pattern of the elevator is detected according to the travel command pattern, and the adjustment correction is detected from the travel command pattern and the travel pattern. When an elevator is installed in a high-rise building, correction values for travel command patterns can be easily calculated.

Further, since the correction value of the travel command pattern is calculated and the correction value of the intermediate portion thereof is calculated, accurate correction values down to the details can be obtained.
