Abstract

PROBLEM TO BE SOLVED: To make test work in remodelling at site smooth by conducting a test for an elevator remodelled at site at night and operating the elevator in its original condition in the daytime in a night time coming-in-and-out inhibition building whose number is rapidly increasing. SOLUTION: This elevator controller is provided with a BKRAM 20 storing program of a site remodelling plan or specification data from the outside and a program part controlling an elevator and a test using test conditions related to the program or data in the BKRAM. Consequently, it is possible to carry out the site remodelling plan at the time which meets customer's request so that work time at site can be greatly reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system such as an elevator or an escalator, and more particularly to a microcomputer (hereinafter, referred to as a microcomputer) for controlling an elevator suitable for smoothly remodeling the site after delivery and adding / changing specifications. The present invention relates to an elevator control device using a microcomputer. Also, especially when remodeling the group management elevator, for example, under conditions where there is no traffic in the building,
The automatic diagnosis of the group control elevator can be executed by using the program or the specification data of the modification plan.

[0002]

2. Description of the Related Art An elevator is controlled by a specification table in which an operation control program and customer specifications are written in a ROM of a microcomputer. However, in this case, the building usage changes after delivery, for example, when a building owned by one company is changed to a tenant building, or when the departure floor is moved from the original plan to another floor, Specification change. To do so, transport the ROM data to the site, stop the elevator once, rewrite the ROM, check again whether the contents of the ROM are correct, check the site locally, it takes time and effort, Service was poor.

In order to solve such a problem, Japanese Patent Application Laid-Open
No. 59-39664 describes an R that stores customer specification data.
The data is transferred from the OM to a RAM (hereinafter abbreviated as BKRAM) backed up by a battery, and thereafter can be freely rewritten by an external device. After the rewriting, since the local workers manually test-run the elevator and then visually determine the test results, neither the automatic test nor the automatic determination can be performed.

In Japanese Patent Application Laid-Open No. 1-226678, the elevator after the specification change is trial-operated based on information for trial-running the elevator, and the trial operation result is automatically determined, but the program is easily changed. No test method is disclosed.

[0005]

Conventionally, ROM after delivery
When changing the program, the elevator must be stopped in the daytime, so that the process from writing to the end of the trial operation must be performed in a short time. Furthermore, if the elevator does not operate normally after rewriting the ROM at the site,
It is necessary to decide the time to work taking into account the work of returning to the original state, which is a serious task.

Further, when it is not possible to take time to work in the daytime, work must be performed on holidays and nights. However, in many cases, building management is recently outsourced to a building management company, and work on holidays and nights cannot be performed. It is.

According to the present invention, when a predetermined condition is satisfied, the microcomputer automatically checks the existence of a test condition related to a program or specification data registered from outside in the BKRAM, and controls the elevator using the test condition. I do. afterwards,
Test operation is performed based on the registered test conditions. If all of the test results based on the test conditions pass, the registered program or specification data is partially or entirely replaced with a designated address. After confirming the normal completion of the replacement process, the BKRAM is returned to the normal operation of executing the ROM. In this case, if an abnormality (irrationality of the program, processing time order, etc.) is detected, the BKRAM is not automatically used and the elevator control is executed in the original state, thereby preventing the system from being shut down. it can.

That is, the test operation is confirmed from the execution of writing automatically at the time requested by the customer, so that the amount of work performed by the worker on site is reduced. And the worker is BK
Since the program is written in the RAM, there is no need to temporarily stop the elevator, and it is possible to provide an elevator control device capable of automatically rewriting the ROM by specifying a condition for performing the ROM rewriting work thereafter.

[0009] It is also possible to write a test condition associated with a program or specification data to the BKRAM from a distance.

[0010]

Accordingly, an object of the present invention is to provide:
In an elevator control device equipped with a microcomputer for controlling an elevator and a nonvolatile recording medium,
A non-volatile storage medium storing a first program or specification data used for the current elevator control, and a second program or specification data required for the elevator control to be a locally modified plan registered from outside. When the test condition is stored in the non-volatile recording medium in association with the predetermined condition (set date and time, traffic flow, etc.), the second program stored in the non-volatile recording medium or Equipped with a means to control the elevator using the specification data, it is possible to automatically test the elevator during operation with the above-mentioned remodeling plan. Thus, it is possible to provide an elevator control device which can improve the customer service which can be remodeled on site under conditions that meet customer needs.
