Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to control of an elevator capable of easily changing elevator specification data such as elevator operation status, stoppable floor, speed, and ride comfort stored in storage means included in an elevator control device. Regarding the device.

[0002]

2. Description of the Related Art Elevators are being installed not only in middle- and high-rise buildings but also in small-scale buildings and private houses as a vertical transportation system in buildings. In recent years, the number of installed units has dramatically increased, and the number of units installed in Japan alone exceeds 100,000.

Further, due to the progress of semiconductor technology, most elevators have a structure using a plurality of microcomputers, and are improving performance and downsizing. Microcomputers are used in accordance with diversified configurations such as elevator operation processing, motor control, elevator car processing, elevator hall processing, display devices installed in elevator cars and halls, and elevator monitoring devices.

With the expansion of microcomputers, functions that can be dealt with by software are stored in the form of data called specification data, and the function of the elevator can be changed by changing this data. This specification data is an electrically erasable storage means (generally E
It is stored in an E-ROM).

FIG. 6 is a block diagram showing an example of this conventional elevator control device, which is generally composed of a microcomputer, a main control device consisting of peripheral equipment and an auxiliary control device such as a transmission control device, and a relay. Has been done.

That is, the microcomputer of the main control unit 9 has a central processing unit (CPU) 1, a peripheral nonvolatile read-only storage unit (EP-ROM) 2 and a volatile read / write storage unit (RAM). 3, electrically erasable storage means (EE-ROM) 4 is provided, and the EE-R
The specification data or the program is stored in the OM 4 as described above.

Further, the peripheral equipment comprises a digital input section 6 for converting the signal from the relay contact 5 so that the CPU 1 can read it, and a digital output section 8 for driving the relay coil 7.

Here, the digital input unit 6 is insulated from the external relay contact 5 by a photocoupler and then converted into a signal having a voltage of about 5V. Conversely, the digital output section 8 is 5V
A certain degree of signal is output to the relay coil 7 after being insulated by the photo coupler.

The transmission control device 10 controls transmission data, and a transmission control DP-RAM 11 which is a common RAM for transmitting the data received from the elevator side to the CPU 1 of the main control device 9, and data communication. It is configured by the transmission CPU 12 that executes

Here, the DP-RAM 11 is a dual port RAM, which is a RAM capable of managing data in common by two CPUs. In the conventional elevator control device described above, a first specification data changing method for changing the specification data in the EE-ROM 4 will be described below.
And the second example. That is, in the first example, in a slight data change, the maintenance staff of the elevator maintenance company attaches the maintenance device for the microcomputer (referred to as console) to the control device in the elevator machine room, and communicates with the elevator control device. It is a method of executing and changing the data.

The second example is an EE-R in which the specification data of the control device provided in the elevator machine room by the maintenance staff of the elevator company is stored when the specification data is significantly changed.
This is a method implemented by replacing OM4.

[0012]

In order to drastically change the specification data as in the second example, the maintenance personnel need to change the EE-ROM4.
Since it is necessary to replace the IC (integrated circuit), there are the following problems. That is, IC of EE-ROM4
For replacement, the IC is removed from the IC socket mounted on the board by using a dedicated tool and replaced with an IC prepared in advance in which data is written. At this time, there is a problem that the pattern of the substrate may be damaged, the elevator may not operate, or the pins of the IC may be bent or broken. Further, the IC may be electrically damaged due to an error in the insertion direction of the IC.

When such an accident occurs, the maintenance staff cannot deal with the problem locally, and as a result, the elevator must be stopped for several hours. On the other hand, due to the progress of semiconductor technology, ROM is shifting to an electrically batch erasable storage device called a flash memory. Although this flash memory has characteristics relatively similar to EE-ROM, it is an IC that can be integrated at high density. As a result of this high density integration, the IC package is DIP
From the mold (dual-in package) to the surface mount type, it has become difficult to use the IC socket as described above.

As a matter of course, the surface mounting has an advantage that the mounting of the IC can be increased and a low-cost device can be supplied, but on the other hand, there is a drawback that it is difficult to deal with the failure of the substrate. This is specifically because the IC is soldered and the specification data cannot be easily transferred to a new board.

In a system in which passengers are loaded in real time, such as an elevator, it is necessary to handle the specification data with great care. In other words, since the specification data contains important specification data such as elevator operating status, stop floors, speed, and riding comfort, the elevator system may go down if these data are entered incorrectly. Because there is.

If the elevator fails in the case of changing the specification data, it may be possible to trap passengers in the elevator car for a long time, and the degree of influence thereof is great, which causes social problems. Therefore, the elevator has been required to have a more reliable system configuration than a general system.

An object of the present invention is to eliminate the problem at the time of exchanging a board in a system capable of changing the specification data of an electrically erasable storage means, and to use an integrated circuit having a high degree of integration. An object of the present invention is to provide an elevator control device that can be downsized.

Embodiments of the present invention will be described below with reference to the drawings. The elevator control device of the present invention is configured such that the specification data is stored in a plurality of storage means in a reconfigurable form and the specification data can be installed from the auxiliary control device when an event such as a substrate exchange occurs.

This will be described below. FIG. 1 is a block diagram of a first embodiment of an elevator control device. This is a main control unit 9 and an auxiliary control unit such as a transmission control unit 1.
0, and the main controller 9 and the transmission controller 10 are each provided with a connector 13, and both connectors can be electrically connected to each other and can be separated from each other.

The main controller 9 is a CPU of about 16 bits
(Central processing unit) 1, an EP-ROM 2 that stores software for driving the CPU 1, a RAM 3 that stores data, and an EE-ROM 4 that stores different elevator specification data depending on the customer.

The transmission control device 10 controls transmission data, and is a transmission control DP-RAM (dial port RAM, that is, data shared by two CPUs) which is a common RAM for transmitting the received data to the CPU 1. RAM 11 that can manage data, a transmission CPU 12 that executes data communication, and a transmission data storage unit 14 that is an electrically erasable storage device like the EE-ROM 4 described above.

The transmission data storage unit 14 includes a main controller 9
Specification data required by a plurality of CPUs including the CPU 1 will be stored. As shown in FIG. 2, the transmission data storage unit 14 stores the rated speed, the stop floor number, the stop position, etc. as the main control unit data, and the transmission station number, the effective address as the transmission control unit data. ,
Listener / talker settings etc. are saved.

FIG. 3 shows an external view of the control device of this embodiment. The main controller 9 is responsible for the main functions of elevator control, and is in the form of a large board. A plurality of connectors 13 are attached to this board so that an extension board can be connected thereto. The transmission control unit 10 has a small-sized board structure, and the transmission data storage unit 14 is composed of a surface-mounted IC. The connector 13 often has about 96 pins, for example, and couples signals such as a data bus and a power supply.

The operation of the elevator control device configured as described above will be described with reference to the flowchart shown in FIG. FIG. 4 shows a flowchart centering on the processing executed in the CPU 1 and the transmission CPU 12 when the substrate of the main controller 9 is replaced.

A step S1 judges the contents of the EE-ROM 4. That is, in general, EE-
Since the content of the ROM 4 is in the initial state and is invalid as the specification data, this determination is executed.

Step S2 is a process when it is determined in step S1 that the substrate has been replaced. That is, CP
U1 requests the transmission CPU 12 to transfer data from the transmission data storage unit 14. As a result, the transmission CPU 12 uses DP
-Transfer its own data to the CPU 1 via the RAM 11.

In step S3, it is determined whether the transferred data is valid. In step S4, the specification data transferred to the EE-ROM 4 of the main controller 9 is written when the determination in step 3 is valid.

Step S5 shows a normal elevator normal operation process. In step S6, it is determined whether the specification data has been changed by the operation of the maintenance personnel or the like.

-ROM 4 and transmission data storage unit 14 have been updated to have the same contents.

Step S8 is a case where it is judged that the transfer data is abnormal in step 3, but since it cannot be automatically processed, the abnormal state is notified. EE-RO
Since the data writing time to M4 is completed in about 2 seconds, the process increase time due to the substrate exchange has almost no effect, and the time required for the IC exchange is shortened considerably.

As described above, according to the embodiment of the elevator controller of the present invention, even when the substrate of the main controller 9 is replaced, the specification data stored in the auxiliary controller, that is, the transmission controller 10 can be installed at the initial stage. Even if an emergency trouble occurs, it can be shaped without problems. As a result, a highly reliable elevator control device can be obtained.

Next, in the embodiment of FIG. 1 described above,
For example, if a 16-bit CPU 1, a program capacity of 128 Kbytes, a RAM 3 of 32 Kbytes, and an input / output register of about 64 points are provided, the elevator can be controlled.

In this case, the size of the data and the program, which can be expected to be changed, is about 256 Kbytes, and the contents are EE-ROM 4 and EP- in FIG.
It is stored in the flash memory 4A which is provided instead of the ROM 2 instead of the ROM 2.

The transmission CPU 12 is a 16-bit one-chip microcomputer, which is in charge of high-speed data communication and in charge of elevator call response processing. The DP-RAM 11 is a dual port RAM having a capacity of about 2 Kbytes.
It has become. The transmission data storage unit 14 has the same capacity as the specification data unit of the flash memory 4A.

In this case, the flash memory 4A has the same configuration as that shown in FIG. 2 and stores the specification data necessary for elevator control. However, the transmission control device 10
Besides, data of an electric motor control unit, an operation monitoring control unit, a door control unit, and the like are also stored, and all data for driving the elevator are collected in the flash memory 4A. Since this data is also stored in the transmission data storage unit 14, operation can be continued by using at least one of the data.

The flow chart for executing the embodiment having the flash memory 4A is almost the same as that of FIG. 3, except that only the process of S4 of FIG. 3 is changed as follows. That is, since the flash memory 4A is in a form of batch erasing in units of a plurality of banks, for example, in units of 64 Kbytes and 8 Kbytes, the data writing format of step 4 is that the specification data portion is once stored in the RAM 3 and then the specification data is stored. Erase and then write.

According to the present embodiment, it is not necessary to use the EE-ROM 4 independently installed in the transmission data storage unit 14 and to dispose the EE-ROM 4 in the main control unit 9 and the transmission control unit 10. As a result, the degree of integration is increased. Since a high IC can be used, there is an advantage that miniaturization can be implemented. Since the flash memory 4A is used, the size of the board can be reduced,
The cost can be reduced.

In the above-described embodiment, the transmission controller 10 is used as an auxiliary controller, but the present invention can be modified as follows in addition to this. (1) Instead of the transmission control unit 10 of the above-described embodiment, an electric motor control unit for performing motor control may be used.

The electric motor control unit, like the transmission control unit 10, has a C
The PU controls the elevator motor. For this reason, the specification data exists under the control of the CPU, but it can be realized because the specification data is configured to interface with the main control unit 9. However, the electric motor control unit is a part of the main control unit 9, and it is not preferable to have a separate configuration like the transmission control unit 10. Therefore, in the case where the substrate is damaged, the storage device should be detached from the IC socket in the case where the memory for storing the specification data on the IC socket is placed.

(2) The specification data may be shared with the remote monitoring device that manages the state of the elevator. This example will be described with reference to FIG.

A remote data interface unit 15 located in the transmission control unit 10 connects the elevator main control unit 9 with a remote monitoring device 17 via a transmission line 16. The remote monitoring device 17 is a device that performs data communication with the elevator maintenance company 19 via the public line 18 for an elevator occurrence and preventive maintenance.
Almost all elevators are installed in modern elevators.

The present invention can be implemented by providing the remote data storage unit 21 in the remote monitoring device 17 and transmitting and receiving the specification data via the transmission path. The same effect can be obtained by storing the specification data in the database 20 installed in the maintenance company 19.

In this case, since all the elevators can be centrally managed, the maintenance company 19 can grasp the specification data conventionally stored in each elevator unit, and the processing becomes easy when trouble occurs.

(3) Instead of the EE-ROM 4, which is one of the means for changing the elevator program of the above-described embodiment, a memory card device including a memory card and a memory card control unit is used, and the elevator program is stored in the memory card. May be stored.

This memory card device stores specification data in a memory card that can be connected to the expansion bus of the main control section 9, and can be configured to be easy to remove, which is a feature of the memory card.

(4) Further, the specification data transfer command of the flash memory 4A is executed in step 1 of FIG. 3, but in the embodiment, the initial state of the flash memory 4A is detected, but C
This can be realized by inputting a transfer command to the PU1 to the digital input unit 6 by using a jumper pin or the like. A method of giving a transfer command to the CPU 1 using a maintenance device or the like may be used.

[0053]

According to the present invention, in the system in which the specification data of the electrically erasable storage means can be changed, the problem at the time of exchanging the substrate can be eliminated and an integrated circuit having a high degree of integration can be used. Therefore, it is possible to provide an elevator control device capable of downsizing the substrate.
