Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to an elevator control device capable of changing programs and specification data relating to the control.

[Prior Art] An elevator control device has been proposed, for example, in Japanese Patent Laid-Open No. 60-93068. The outline will be described with reference to FIG.

In the figure, the elevator equipment 1 is controlled by an elevator control microcomputer 2, and the microcomputer 2 is a read-only memory 20.
(Hereinafter referred to as ROM), battery-rewritable rewritable random access memory 30 (hereinafter referred to as RAM), normal RAM 40, input / output device 50, microprocessor unit 60 for performing logical operation (hereinafter referred to as MPU), And a clock generator 70 which issues a clock signal for this MPU 60.

ROM20 has this elevator operation control program 20
a, specification data 20b determined by the function of the elevator and the building conditions are stored. This specification data is data for instructing the reference floor, the door opening / closing time, the parking floor, etc., as described in the above publication.

The transfer command switch 5 issues a command for transferring the specification data 20b to the RAM 30 that is backed up, and the MPU 60 determines that the transfer command switch 5 has been operated and transfers the specification data 20b to the RAM 30. Transfer and store.

In such an elevator control device, the specification data may need to be changed depending on the user's wishes, changes in usage conditions, or the like. In this case, ROM20
The specification data 20b is stored in the RAM 30 by the transfer command switch 5 without replacing the whole, and the specification data 20b stored in the RAM 30 can be freely rewritten by the writing device 6.

That is, when the specifications are changed, the writing device 6 causes the RAM 30
By rewriting the specification data 20b stored in the specification to a desired specification, it is possible to deal with the specification change quickly and easily.

[Problems to be Solved by the Invention]

In the conventional device, since the specification data 20b stored in the RAM 30 was rewritten, the RAM 30 and 40
When the memory of the specification data and the like stored in the memory is erased, the specification data 20b before rewriting is obtained, and it is necessary to rewrite the specification data to be changed again.

Further, since the rewriting process is performed in the writing device 6 every one step, rewriting is not easy when there are many rewriting steps of the specification data.

Further, in the conventional device, rewriting of the operation control program 20a requires specialized technology in order to avoid the risk of program destruction at the time of rewriting. Therefore, the ROM 20 or the microcomputer 2 as a whole is removed and once pulled up from the site, another A specialist engineer was rewriting at some point. Therefore, rewriting the operation control program 20a requires a lot of trouble and time.

The object of the present invention is to solve the above-mentioned problems in the conventional technology,
Customers such as elevator owners and managers can easily deal with changes in specification data after delivery of elevators, and for changes including operation control programs, change operators are limited to specialized engineers. It is to provide an elevator control device that can perform.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an operation control program for controlling the operation of an elevator, specification data determined by the function of the elevator and usage conditions of a building, and an abnormality of the elevator. An elevator control device for controlling the elevator by using an elevator monitoring device for monitoring the operation control program, stores the operation control program and the specification data, is electrically rewritable, and retains the stored content even when the power is cut off. First storage means, second storage means for storing at least one of the operation control program and the specification data, and input for inputting data of the second storage means provided in the elevator monitoring device. Part and the inside of the elevator monitoring device, and the second Rewriting permission signal output means for outputting a signal permitting rewriting when the operation control program is stored in the storage means, and the rewriting permission signal output when the data of the second storage means is input to the input section. Data change means for rewriting the data stored in the first storage means to the data input from the input section while determining the presence or absence of a signal from the means are provided.

[Action]

When changing the operation control program for controlling the operation of the elevator or the specification data determined by the function of the elevator and the usage conditions of the building, or both of them, the change data is stored in the second storage means such as an IC card, This is input from the input section of the elevator monitoring means. The input change data is transferred to the first storage means and stored in place of the operation control program and specification data already stored in the first storage means. In this case, regarding the rewriting of the operation control program or the operation control program and the specification data, the rewriting is performed only when the permission signal is output from the permission signal output means. Since the permission signal output means is housed inside the elevator monitoring device, it cannot be operated by the customer such as the elevator owner or the person in charge of management. It is possible to prevent a risk of destruction of the operation control program, which is caused by a person rewriting the operation control program without permission.

〔Example〕

 Hereinafter, the present invention will be described based on the illustrated embodiments.

FIG. 1 is a block diagram of an elevator control device according to an embodiment of the present invention. In FIG. 1, those parts which are the same as those corresponding parts in FIG. 4 are designated by the same reference numerals, and a description thereof will be omitted. 2'is an elevator control microcomputer used in this embodiment, and 3 is an IC card in which an operation control program 20a, specification data 20b, etc. are written. In this IC card 3, a region is defined for each rewriting target. Reference numeral 4 denotes a monitoring device for monitoring the occurrence of an abnormality in the elevator, which is composed of a micro computer. In addition to the function of a normal monitoring device, this monitoring device 4 has a function of inserting the IC card 3, reading the stored contents, and transferring this to the elevator control microcomputer 2 '. 4D is a rewriting indicator light that lights up only while a writing operation is being performed. 7 is a switch (rewriting permission signal output means) used when rewriting the operation control program 20a,
By operating this switch 7, a signal permitting rewriting of the operation control program is output. by the way,
Generally, the operation control program 20a can be correctly rewritten only by a professional engineer, and it is not desirable for a person other than a professional engineer to rewrite it because a large risk such as destruction of the operation control program is caused. It is housed inside the monitoring device 4 and cannot be operated by anyone other than a professional engineer. 20 'is provided in the elevator control microcomputer 2', and is an electrically erasable and programmable read only memory (hereinafter abbreviated as EEPROM) that stores an elevator operation control program 20a, specification data 20b and the like. The storage means is capable of rewriting stored data. FIG. 2 shows a memory map of the specification data 20b stored in the EEPROM 20 '.

In Fig. 2, 20b ₁ is various timer values for control such as door opening / closing time, 20b ₂ is model sorting data such as elevator speed and loading capacity, 20b ₃ is data for judging presence / absence of additional specifications such as seismic control operation, 20b ₄ Is the building condition data such as the floor of the elevator.

FIG. 3 is a flowchart showing a process until the specification data 20b in the EEPROM 20 'or the operation control program 20a and the specification data 20b are rewritten.

The process until only the specification data 20b is rewritten will be described using this flowchart. First, the IC card 3 in which the changed specification data is written is first inserted into the elevator monitoring device 4. Then, it is determined whether or not there is a signal 3S output when the IC card 3 is inserted (step S ₁ shown in FIG. 3). In this case, since it is determined that the signal 3S is present, the monitoring device 4 suspends the monitoring state and enters the writing state (step S ₂ ). Next, it is determined whether there is a signal 7S when the switch 7 is operated (Step S _3). In this case, since the switch 7 is not operated, the signal 7S is not generated,
Monitoring apparatus 4 reads only the change specification data area of the IC card 3, and transfers the data to the elevator control microcomputer 2 '(Step S _9). Then, based on the transferred the data was 'in, EEPROM 20' elevator control microcomputer 2 rewriting process only changes location area specification data 20b in is carried out (Step S _10).
Next, when this rewriting process is completed, the rewriting indicator light
4D are turned off (Step S _6). When Off rewrite indicator 4D is confirmed, remove the IC card 3 from the monitor 4 (Step S _7). Yotsute to remove the IC card 3, the monitoring device 4 from the write state, the elevator monitoring state is the first state (Step S _8). With the procedure up to this point, the rewriting process of only the specification data 20b is completed.

Further, the operation control program 20a only, or rewriting of both simultaneous this and specification data 20b, by executing after the determination in the previous step S _3, the procedure S _4, S ₅ in accordance with step S _9, S ₁₀ Done. That is, the elevator monitoring device 4
Read change data area of the operation control program stored or operation control program and specification data, the IC card 3, and transfers these data to the microcomputer 2 '(Step S _4). Then, based on the transferred data, the EEPROM 20 'is set in the microcomputer 2'.
Rewriting process only changes location area of the operation control program 20a 'or operation control program 20a and the specification data 20b of the inner is performed (Step S _5).

In the above description of the embodiment, the storage means of the elevator control microcomputer is exemplified by the EEPROM, but the storage means is not limited to this, and a rewritable storage means such as a backup RAM can be used. Further, instead of the IC card, other appropriate storage means can be used.

〔The invention's effect〕

As described above, in the present invention, the EE is stored in the first storage means.
A storage means, such as a PROM, that is electrically rewritable and that retains the stored contents even when the power is cut off is used, and the second storage means, such as an IC card, uses the operation control program and the specification data to be changed. At least one is stored, and based on this, the operation control program and specification data are changed using the existing microcomputer for the elevator monitoring device and the elevator control microcomputer, so it is possible to easily rewrite on site. it can.

In addition, for rewriting of only the specification data, the owner of the elevator or the customer in charge of management can easily rewrite.

Further, regarding rewriting of the operation control program or both of the operation control program and the specification data, it is possible to rewrite on-site without the trouble of removing, carrying, and attaching the storage section or the micro computer for rewriting. In addition, in addition to this, the rewriting permission signal output means housed inside the elevator monitoring device limits the change operator to a professional engineer, and the customer cannot operate it, such as the owner of the elevator or the person in charge of management. Thus, it is possible to prevent the risk of program destruction or the like caused by a person other than the expert engineer rewriting the operation control program without permission.
