[0001]
[Industrial applications]
The present invention relates to an elevator running characteristic recording device, and more particularly, to an elevator running characteristic recording device that records together acceleration data and speed data of an elevator to check whether the ride quality of the elevator is good.
[0002]
[Prior art]
In general, when an elevator has a poor ride during operation, not only does the passenger feel uncomfortable but also anxious. For this reason, it is extremely important to maintain good ride comfort when operating the elevator in maintaining the elevator. In this case, it is known that the riding comfort of the elevator largely depends on the speed control characteristics, the installation accuracy of the elevator, or the state of a guide for guiding the traveling of the elevator car.
[0003]
Conventionally, an elevator traveling characteristic inspection device has been used to inspect the ride comfort of an elevator. Such an elevator traveling characteristic inspection device includes an acceleration detector that detects acceleration during traveling of the elevator, and a recording device that records a detection output of the acceleration detector. When the installation of the elevator is completed, At the time of normal maintenance and inspection, the elevator car is run, and the acceleration acceleration of the elevator car in the up, down, left, right, and front and back directions during running is measured by the acceleration detector, and the measurement result is recorded in the recording device. The recording is performed, and the quality of the ride of the elevator is determined based on the recorded data.
[0004]
[Problems to be solved by the invention]
The known elevator traveling characteristics inspection device, when running the elevator car, when measuring the acceleration during traveling, to set the start point and end point of the measurement, etc. Although it is necessary to perform the operation, even if the user carefully pays attention to the operation of such a manual switch, the operator transmits artificial unnecessary vibration to the acceleration detector, and accurate acceleration data is obtained. There is a problem that you can not.
[0005]
Further, in the known elevator running characteristic inspection apparatus, the timing of performing the operation (on / off operation) of the manual switch tends to be irregular with respect to the running of the elevator car, and furthermore, the variation varies depending on the operator. For this reason, there is also a problem that a great deal of time is spent for organizing data after measurement of acceleration data is completed.
[0006]
In order to solve such a problem, some of the known elevator running characteristic inspection devices include an unmanned running of an elevator, and continuous recording during the running, thereby preventing artificial unnecessary vibration based on operation of a manual switch. Although there is a method that eliminates the occurrence, such continuous recording means that the acceleration data is also measured during the period when the measurement of the acceleration data is not required, which causes a new problem that a lot of waste occurs. In addition, the problem that it is necessary to spend a great deal of time on data arrangement after the measurement is completed has not been solved.
[0007]

[0016]
Next, FIG. 2 is a flowchart showing a processing operation performed by the CPU 4 in the embodiment shown in FIG. 1, and FIG. 2 (a) shows a data input processing operation in acceleration data. (B) shows an automatic data recording operation.
[0017]
The operation of the embodiment shown in FIG. 1 will be described with reference to the flowcharts shown in FIGS. 2 (a) and 2 (b).
[0018]
First, the data input processing operation on the acceleration data is executed by the following operation process.
[0019]
First, in step S1, the CPU 4 determines the vertical acceleration data (first acceleration data) of the elevator car obtained by the first acceleration sensor 1A and the elevator car obtained by the second acceleration sensor 1B. , And the acceleration data in the front-rear direction (third acceleration data) of the elevator car obtained by the third acceleration sensor 1C are detected at regular intervals.
[0020]
Subsequently, in step S2, the CPU 4 determines that the first acceleration data digitized by the first A / D converter 2A, the second acceleration data digitized by the second A / D converter 2B, The third acceleration data digitized by the third A / D converter 2C is taken in.
[0021]
Next, in step S3, the CPU 4 calculates first to third speed data based on the taken first to third acceleration data.
[0022]
Subsequently, in step S4, the CPU 4 stores the data recording memory card 11 in the connector section 10 already, and stores the captured first to third acceleration data and the calculated first to third speed data in the data. It is determined whether or not recording on the recording memory card 11 is possible. When it is determined that recording is possible (Y), the process proceeds to the next step S5. On the other hand, when it is determined that other data is being recorded and recording is not possible (N), other data is recorded. The process moves to step S6.
[0023]
In the following step S5, the CPU 4 transfers the captured first to third acceleration data and the calculated first to third speed data to the connector unit 10 and causes the data to be recorded in the data recording memory card 11.
[0024]
In step S6, the CPU 4 supplies the acquired first to third acceleration data and the calculated first to third velocity data to the display 7, and the display 7 displays the acceleration data and the corresponding acceleration data. Display speed data side by side on the same time axis. Then, after each acceleration data and the corresponding speed data are displayed on the display 7, the process returns to step S1, and the operations after step S1 are repeated again.
[0025]
Next, an automatic data recording operation performed in parallel with each operation in step S5 will be described with reference to FIGS. 3A and 3B described below.
[0026]
Here, FIG. 3A is an explanatory diagram schematically showing a memory structure in the data recording memory card 11, and FIG. 3B shows an example of a change state of the speed data over time. FIG.
[0027]
First, in step S10, the CPU 4 sets a memory storage point of the data recording memory card 11 to an initial value p1.
[0028]
Subsequently, in step S11, the CPU 4 determines whether or not the size of the speed data has exceeded the first set value S1. When it is determined that the first set value S1 has been exceeded (Y), the process proceeds to the next step S12. On the other hand, when it is determined that the first set value S1 has not been exceeded (N), this step S11 is performed. Is repeatedly executed.
[0029]
Next, in step S12, the CPU 4 changes the memory storage point of the data recording memory card 11 from p1 to p2. In this case, the memory length from the memory storage point p1 to the memory storage point p2 is set to have a size corresponding to the time t1.
[0030]
Subsequently, in step S13, the CPU 4 determines whether or not the size of the speed data has decreased below the second set value S2. When it is determined that the value has decreased to the second set value S2 or less (Y), the process proceeds to the next step S14, while when it is determined that the value has not yet decreased to the second set value S2 or less (N). Repeatedly executes this step S13.
[0031]
Subsequently, in step S14, the CPU 4 determines whether or not the time t2 has elapsed since the size of the speed data has decreased to the second set value S2 or less. When it is determined that the time t2 has elapsed (Y), the process proceeds to the next step S15. On the other hand, when it is determined that the time t2 has not elapsed (N), the step S14 is repeatedly performed. In this case, when the elapse of the time t2 in step S14 is confirmed, the CPU 4 temporarily ends the recording of the acceleration data and the speed data.
[0032]
Finally, in step S15, the CPU 4 rearranges the already recorded acceleration data and speed data within the time t1 into a time-series arrangement, returns to step S10 again, and repeats the operations from step S1 onward. Is done.
[0033]
In this case, in the data automatic recording processing operation, the acceleration data and the speed data are stored side by side in the memory area on the same time axis in the data recording memory card 11. Then, during a period of time t1 until the magnitude of the speed reaches the set value S1, the acceleration data and the speed data are sequentially stored in the memory storage points from the initial values p1 to p2. When they are sequentially stored in the memory storage points and return to the initial value p1, they are sequentially stored again from the initial values p1 to p2. Here, when the magnitude of the speed data exceeds the set value S1, the memory storage point shifts from p1 to p2. At this time, by storing the last memory storage point in the time period t1, the acceleration data is stored. It is possible to easily rearrange the recording data composed of the speed data and the speed data into a time-series arrangement.
[0034]
Further, the memory storage point p2 is simply updated with the elapse of time, and when the magnitude of the speed data falls below the set value S2, a time t2 period is entered. After the elapse of the time t2, the acceleration data and the speed data Is temporarily terminated. At this time, the memory storage point next to the last memory storage point during the time t2 becomes the initial value p1 of the memory storage point in the next operation of recording acceleration data and velocity data.
[0035]
As described above, according to the present embodiment, the first to third acceleration data obtained by the first to third acceleration detection units 1A to 1C and the first to third acceleration data are separately integrated. The obtained first to third speed data are supplied to the display 7 and the data recording memory card 11, and the corresponding acceleration data and speed data are displayed on the display 7 side by side on the same time axis. At the same time, the same acceleration data and the same speed data are automatically recorded side by side in the data recording memory card 11, so that the first to third acceleration data and the first to third speed data are detected. In addition to being able to see each time, each acceleration data and each speed data can be recorded, greatly reducing the burden of organizing the recorded data such as each acceleration data and each speed data. It can be reduced.
[0036]
Further, according to the present embodiment, the first to third acceleration data obtained by the first to third acceleration detection units 1A to 1C and the first to third acceleration data are separately integrated. When the recorded first to third speed data is recorded on the data recording memory card 11, each speed data from the time point slightly before the rising portion to the time point slightly after the falling portion in each speed data. Since the data and each acceleration data are automatically recorded, only a necessary portion of all the acceleration data and all the speed data can be recorded, and the memory of the data recording memory card 11 is effectively used. In addition to the above, it is possible to reduce the work load when organizing the acceleration data and the speed data later.
[0037]

The corresponding acceleration data and speed data are displayed on the same time axis and displayed on the display unit, and the same acceleration data and speed data are automatically recorded side by side in the recording unit. Thus, not only can each acceleration data and each speed data be detected each time it is detected, but also the recording of each acceleration data and each speed data, that is, the measurement and recording of the running characteristics (ride comfort) of the elevator is automatically performed. In addition to this, there is an effect that the burden on the organization of recorded data such as acceleration data and speed data can be greatly reduced.
