Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides control data at the location where the elevator is installed to the optimal l! This invention relates to an elevator control device that can handle small amounts of data.

[Conventional technology]

FIG. 5 is an overall configuration diagram showing a conventional elevator control device, and numeral 10 indicates a microcomputer provided within the elevator control device. In this microcomputer IO, data from the elevator equipment is input to a central processing unit (hereinafter referred to as CPU) 11 via an interface 12, and this input data is input to a random access memory (hereinafter referred to as RAM) 13. Store. In addition, the value of the low-return switch 9 installed on the board (usually 4 bits, 16 ways of 0 to OFN) is input to the CPU II, and this is stored in the RAM as gain data.
Next, a program in the ROM 14 is executed based on the gain data stored in the RAM 13, and an optimal torque command to the motor is outputted via the interface 12.

In this way, the gain value (OH
-0GN) can be freely selected, it is possible to set the optimum data for each elevator installation site, and thereby perform elevator control with a comfortable ride and high landing accuracy.

Further, in the same way as the gain, by setting the pattern adjustment data using a rotary switch, it is possible to set the optimum data for each site.

In other words, the followability of the speed command value (hereinafter referred to as a pattern) and the car speed differs depending on the capacity of the elevator, the rating of the hoisting machine with a motor rating of 2, and the like. For this reason, during deceleration, a pattern is output using a distance-dependent pattern (hereinafter referred to as a standard pattern) that corresponds to the remaining distance to the stop position. Sometimes the patient may land on his or her own.

In order to solve this problem, Japanese Patent Application Laid-Open No. 56-1612
As shown in Japanese Patent No. 67, adjustment is performed using pattern adjustment data. For example, if the pattern adjustment data value in the standard pattern is 081, the pattern at the remaining distance point A is V, as shown in FIG. It becomes J. Here, if the vehicle overshoots and lands on the floor automatically, the set value is set to Z, and a pattern relatively closer to the floor than the standard pattern is output. In other words, the pattern at the remaining distance point A is Voh (<Vwj), and the landing accuracy is improved. On the other hand, when landing on the seat on the seat, the set value is set to W so that a pattern relatively far from the standard pattern is output. At this time, the remaining distance pattern at point A is V. t (>VI, j).

In this way, by changing the setting values of the rotary switch, the pattern can be adjusted and the landing accuracy can be improved.

In the above conventional example, the gain and pattern adjustment data have been described, but the following control data is also set using a rotary switch for the same reason as above.

(1) Brake adjustment time limit data Check landing accuracy when the elevator stops Brake cutoff timing to improve ng, (ii) Implantation pattern data The landing accuracy when the elevator lands on the floor This is to improve the speed of the car. Pull the pattern negative so that it arrives (but this A negative value is the implantation pattern data.

[Problem that the invention seeks to solve]

In recent years, social needs have required low cost and high performance products, and elevators are no exception. For this reason, conventional elevator control devices are expensive because the control data for each site is adjusted using a logarithm inch.Also, the rotary switch is usually 4 bits, so there are 16 ways to adjust it. It is not suitable for fine-tuning control data to select one value. Therefore, in order to make fine adjustments possible, there is a problem in that two or more rotary switches must be used for one control data.

The present invention was made in order to solve these problems, and aims to provide an elevator control device that has low hardware cost and can easily set appropriate control data at the elevator installation site. do.

[Problems to be solved]

The elevator control device according to the present invention is provided with means for writing into a nonvolatile memory by a handheld computer and means for reading out the nonvolatile memory, and is configured so that data is rewritten by the handheld computer during adjustment.

[Effect]

In this invention, optimal control data can be written into a non-volatile memory by a handheld computer, and the rationality of the data can be checked when writing and reading the control data stored in this non-volatile memory. Because the device reads out high-quality data and uses it for elevator operation, the equipment becomes inexpensive and the data can be easily obtained, making it possible to control elevators with a comfortable ride and high landing accuracy. You can do it.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a configuration diagram showing the basic configuration of the present invention. In the figure, reference numeral 1 denotes a handheld computer, which has recently been used for the installation and maintenance of elevators. This handheld computer 1 is connected to a microcomputer on a control panel by, for example, an R3-232C interface, so that data can be input and output. Here, the main purpose of the handheld computer is to save labor during installation and maintenance by being able to register elevator car calls and hall calls, and displaying the car position on the display. In this invention, the handheld computer 1 is used not only for the above purpose but also as a writing tool for nonvolatile memory. 2 is a nonvolatile memory; 3 is a nonvolatile memory writing means for writing data instructed by the handheld computer 1 into the nonvolatile memory 2; Reference numeral 4 denotes a non-volatile memory readout means for reading data stored in the non-volatile memory 2. The non-volatile memory 2 contains unique information for each building, such as the number of building outages, the presence or absence of options (earthquake control operation, fire control operation, service floor that determines the floor to be serviced depending on the time, etc.), and the like. It is assumed that control data such as ride comfort 1 and floor landing is stored.

Hereinafter, a case will be explained in which the handheld computer 1 is connected to the microcomputer 10 shown in FIG. 2, which is similar to the microcomputer installed in the control panel of an elevator similar to that shown in FIG. 5, through an R3-232C interface. do.

In addition, in the same figure, 16 is the handheld computer 1.
17 is a blectri-cally which is one of non-volatile memories.
and Erasable and Program
mable Read Only Memory (hereinafter referred to as E"FROM) 17. Therefore, this E"F
The ROM 17 stores, for example, gain data supplied from the handheld computer 1 via the interface 16 . And this E”PROM 1
Read the gain data stored in ROM1
By running the program stored in 4.
A torque command is output to the motor via the interface 12. Here, if the gain data settings in the E"FROM 17 are not sufficient, it will greatly affect riding comfort and landing. Therefore, when adjusting during installation and maintenance, it is necessary to connect the handheld computer 1 to the R3-232G interface. It is connected to the microcomputer 10 of the control panel.The optimum gain is set by writing the command value from the handheld computer to the E"PROM 17 via the interface 16, so that the optimum torque can be commanded to the motor. Make it.

As mentioned above, the handheld computer l and E”PROM
By using 17, the gain data can be easily rewritten at low cost, and fine adjustment can be easily performed, so that an elevator with a comfortable ride and high landing accuracy can be obtained.

Furthermore, since the gain is control data, when writing data from the handheld computer 1 to the E''PROM 17, the rationality of the written data is checked to prevent inappropriate data from being written. The nonvolatile memory writing means 3 and the nonvolatile memory successive writing means 4 are realized by software (program), and the second
The program is stored in the ROM 14 shown in the figure. The ROM 14 also stores data and programs necessary for normal elevator operation, such as input and registration of car call 9 hall call, etc.
Programs such as elevator start/stop command speed control and door opening/closing control are also stored and executed by the CP [111].

That is, in the nonvolatile memory writing means 3 of FIG.
FIG. 3 shows a case where the rationality of write data commanded from a handheld computer is checked and then written.

For example, if the handheld computer 1 commands the gain to be set to X, the CPU 11 inputs this in step 20. Here, if the gain is only allowed to have a value from O to OFI, then this command value
If satisfies 0≦X≦OF in step 21, the process moves to step 22 and writes X as gain data to E"PROrl 17. If not, the data is controlled not to be rewritten. Increase credibility.

This prevents the elevator's ride center value and flooring accuracy from deteriorating by a factor of 11 if the installation/maintenance coordinator mistakenly operates the handheld computer 1 and sets an inappropriate value for the gain. This is a necessary measure to achieve this goal.

Similarly, when the CPU i reads out gain data from the E''PROM 17, the validity of the read data is checked.(This will be explained using FIG. 4). Therefore, when the gain data Y in the E"l' ROM 17 is read out in step 30 shown in FIG. 4, since the gain data 4 only has values from 0 to OF, l, this E"
AND of gain data Y in FROM 17 and OFM
The condition is determined, and then the steering knob 32 stores Yl, which is the result of this AND condition, in the RAM 13 as gain data. That is, control is performed so that the value taken into the CPU II as gain data is always between 0 and OF. Thereafter, the gain required for speed control of the elevator is controlled using Yl in the RAM 13.

This means that the data retention period of E"FROM 17 is 10~
This measure was taken to ensure that the data is reliable, as it is not guaranteed for a long period of 20 years.

In this way, when writing to E"PROM 17 and E"P
Since the rationality of the data is checked when data is successively read from the ROM 17, highly accurate control can be performed.

In the above embodiment, when writing to the E''PROM 17.

Check the rationality of the gain data when reading from the E"PROM 17. (a) When writing - If it is illegal, do not write.

(11) When successive occurrences - [0FK to input value] and illega
Mask it so that it does not become l data.

However, the standard gain setting is 081.
If it is 1, (a) When writing - If it is illegal, write the standard setting value o8°.

(Sweet) If it is consecutive -4llegal, the standard setting is 08M
is imported into the CPU.

You can also use it as

Further, in the above embodiment, the control data is set from O to OF.

However, if E"FROM is used, it is not limited to the above, and the degree of freedom is greater,
For example, it can be easily changed to vary from θ to 2F, l. (Previously, due to cost constraints, one piece of data was limited to one rotary inch (0 to OFM))
.

In the above embodiment, the case of gain data was explained, but other control data (pattern adjustment data, brake adjustment time limit data, floor landing pattern data) mentioned in the conventional example, and building-specific data (optional function data) can also be used. presence or absence)
etc., and in this case, the same effect as in the above embodiment can be achieved.

Also, depending on the control data, (a) When writing - If illegal, write the maximum or minimum value within the allowable range of the data.

(b) When reading - If it is tllegal, the maximum or minimum value within the allowable range of data is taken into the CPU.

It's good as well. Here, whether the maximum value or the minimum value is set depends on the data. For example, if it is time limit data for brake adjustment, the minimum value is safer because the brakes are applied sooner. However, if it is the landing pattern data, the maximum value is safer because the car speed is faster (closer to 0).

Furthermore, in the above embodiments, the case where a non-volatile memory is used has been explained, but the invention is not limited to this, and the same effect can be obtained by combining a volatile memory (RAM) and a battery, or a combination of a RAM and a capacitor, etc. play.

〔Effect of the invention〕

As described above, according to the present invention, control data, which is data for adjustment during installation and maintenance, is stored in a nonvolatile memory, and the data is rewritten by a handheld computer during adjustment, so that the device can be easily operated. It can be done cheaply.

In addition, when data is written and continuously output, the data is controlled to check the rationality of the data, so highly reliable data can be obtained. This has the effect of enabling elevator control.
