Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator control device, and more particularly to an improvement of a device using a digital computer in an elevator control section.

[Conventional technology]

In recent years, microcomputers (hereinafter referred to as microcomputers) are used in control units.
An elevator control device that employs this has been put into practical use.

As is well known, this microcomputer mainly consists of a central processing section, a storage section, and an input/output section, and this storage section further consists of a read-only storage section and a rewritable storage section. This read-only storage section has high reliability against power outages, noise, etc., and therefore stores elevator operation control programs, elevator specification data, and the like. This specification data is determined in advance based on the function of the elevator and the conditions of the building to be delivered, such as door opening time, number of floors in the building, floors to be serviced by the elevator, standard floors, non-stop floors, etc. be.

The operation of the elevator is controlled based on this operation control program and specification data.

Elevator control devices using such microcomputers pose new problems that do not exist in conventional relay circuits, and for example, British Patent Publication No. 2025663 proposes a testing method for the same.

In addition, in the same No. 2063522, since the car position detection process becomes impossible during a power outage, a method for detecting the car position during a power outage is proposed, and the same No. 2063521
The issue describes the improvement of car position detection accuracy using a microcomputer.

After the elevator is delivered, if there is a change in function or building conditions, such as an increase in the number of floors in the building due to an extension, and you want to change the elevator specifications.

It is conceivable to deal with this change by manufacturing a new read-only storage section that stores the specification data and replacing it with the existing storage section.

However, for this purpose, each time the specifications are changed, it is necessary to confirm the previous specifications, check the program management number, etc. with the elevator, manufacture a storage section, and carry out on-site replacement work and inspection.

Therefore, the work time and cost required for this replacement were enormous, and it was difficult to promptly deal with this change in specifications.

Therefore, in order to solve this problem,
A device as disclosed in Japanese Patent No. 68 was proposed.

According to this technology, it is possible to change or cancel standard floors and parking floors due to changes in building usage conditions, change the number of floors due to building expansion, change door times, set non-stop floors, and make desired floors non-stop. It is easy to change various specification data included in the specification data, such as changing the operation pattern that automatically switches between the state and the stopped state depending on the time period,
Changes in specifications after delivery can be easily dealt with, and moreover, can be done in a short time on site, making it possible to realize an elevator with excellent customer service and economy.

[Problem that the invention seeks to solve]

However, this conventional technology has the limitation that it can only be operated by a specialized engineer, such as a maintenance worker at an elevator company, and can be used to change door times, standard floors, parking floors, If a customer requests after delivery the setting of a non-stop floor and the setting of an operation pattern that automatically switches the desired floor between a non-stop state and a stopped state depending on the time period, the maintenance company should promptly respond to these requests and set a regular schedule. This has the disadvantage of increasing maintenance costs as the customer has to go to the site to deal with the problem outside of the contracted maintenance days.

In addition, in order to eliminate such drawbacks, we have created a data card whose specification data can be changed according to customer requests for each of the above functions, and installed a reading device for this data card on the elevator side. It is conceivable to hand out data cards to customers, but this would require multiple types of data cards depending on the elevator conditions, which not only increases the manufacturing cost of the elevator, but also makes it difficult for customers to use such data cards. There are cases where it is unnecessary, making it uneconomical as an elevator system.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator control device that allows the customer to easily change two sets of functions after delivery.

[Means for solving problems]

In order to achieve the above object, the elevator of the present invention is an elevator control device that is equipped with a computer and that sets operating conditions based on data given by a specification table, which is one of a plurality of specification tables of different types. The specification table has a specification table selection and reading means capable of selecting one of the data and reading the data, a data card storing predetermined data, and a reading device for reading the data of the data card into the elevator operating panel. The selective reading means has a data card inserted into the reading device, and
By operating an operation button provided on an elevator operating panel, a specification table corresponding to the operation is read out from the specification table and stored in the operating condition setting means.

[Effect]

In the elevator control device of the present invention, if the customer changes the usability after delivery, the customer inserts the data card containing the data into the card reading device provided on the driving panel, and By operating the operation buttons arranged in accordance with a preset operating procedure according to a change in operating conditions, a specification table reading selection procedure reads data from the specification table and stores it in the operating condition setting means. Therefore, when the customer wishes to change the operating conditions due to convenience, there is no need to request the dispatch of a specialist engineer from a maintenance company, and there is no need to install multiple types of data cards.
