DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator control apparatus according to the present invention will be described below in detail with reference to FIGS. The same components as those of the conventional elevator control device shown in FIGS. 9 and 10 are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 is a configuration diagram of an elevator to which a first embodiment of an elevator control device according to the present invention is applied.

That is, the present invention relates to an elevator having a high function and high performance by, for example, replacing a drive motor of a hoist or installing an abnormality detection sensor. In order to perform the process efficiently, in the first embodiment, the substrate 1
As shown in FIG. 2, instead of the package of one IC containing the above-mentioned program storage unit, three circuits having different functions including the one IC are obtained by miniaturization by increasing the degree of integration of circuits and elements. Are housed in a single IC package 22, which is replaced by the single IC and mounted on the substrate 1.

I stored in one IC package 22
C, first, the first IC 221 is transferred with the current operation data of the elevator and the existing specification data including the operation program from the specification data storage unit 5 via the bus line 3 and copied. Is loaded with new operation data and second specification data including an operation program, which are upgraded in accordance with the high function and high performance of the elevator.

In the second IC 222, a current control program is transferred in advance, and a second control program in which a program for upgrading is added to the control program is stored in advance. 3 I
The current control program is stored in C223 in advance.

Therefore, the second control program can transfer and store the existing specification data to the first 1C 221 and upgrade the stored existing specification data.

More specifically, the first IC 221
The second and third ICs 22 are composed of 32K bytes of EE-ROMs formed of P (surface mounting elements having a narrow pitch).
2,223 was constituted by a 256K byte flash ROM also formed of TSOP.

Therefore, in the rewriting operation of the first IC 221 to the second specification data, the operator operates the switch (not shown) provided on the substrate 1 to activate the CPU 2 as in the prior art, and then starts the operation. The first IC 221 is configured as shown in FIG. 3, and the data write register 221a is connected to the bus line 3 by the additional program for the second IC that has been controlled to be activated by the CPU 2. The data D0 is input by a data input operation by an operator from a control console connected to the connector 13
Only when a signal of “1” is supplied to the line, a signal of “0” is supplied to the data D1 line, and a signal of “1” is supplied to the data D2 line,
The write command WR from the CPU 2 is transmitted to the EE-ROM 22
1b, it becomes possible to write operation data and an operation program for upgrading and a corresponding address. That is, the first IC 221 is switched to enable or disable writing of the specification data by an input operation to the data writing register 221a by the operator, thereby preventing the stored data from being accidentally rewritten due to noise or the like. And the renovation work can proceed smoothly.

In this embodiment, the second IC 2
The control program of No. 22 is provided with the conversion table shown in FIG. 4, and when checking the operation of the elevator, even if the address of the existing specification data (6) is specified by the input operation from the control console by the operator, the second It is configured to be automatically converted to the address of the specification data. Therefore, even if the address of the conventional specification data is mistakenly specified during the maintenance and inspection of the elevator of the worker, the address is automatically converted to the address of the upgraded second specification data and read-out control is performed. Maintenance inspection work can be performed easily.

The operation of the elevator in the control system repair in the first embodiment having the above configuration will be described with reference to the flowchart shown in FIG.

First, the operator firstly operates the first to third ICs 22.
One IC package 22 mounting 1 to 223 is mounted on the substrate 1 instead of an IC (program storage unit 4) mounting an existing control program. That is, the third and second ICs 223 and 222 store an existing control program and an additional control program in which an additional program for upgrading the existing control program is set, respectively. 2 IC222
Then, it is determined whether or not the program addition setting has been made by mounting on the board 1 by reading the signal from the CPU (step 1). By mounting on the substrate 1 (YES), the second IC 2
22 is set and the initial processing is executed, the additional program immediately executes the first IC2.
21, the specification data storage unit 6 via the bus line 3
Then, the storage operation of the already-specified data from the server and the rewriting operation of the transferred already-specified data to the second specification data for upgrading the version according to the modification are started (step 2). At this time, the worker inputs a write command WR from the CPU 2 from a control console connected to the connector 13.
Is transmitted to the EE-ROM 221b.

After the end of step 2, the operator completes the initial processing by the additional setting of the above-mentioned program, and completes the rewriting change to the second specification data whose specification data has been upgraded by the rewriting operation. It is confirmed whether or not it is (step 3).

In step 3, upon completion of the initial processing, the second
Is confirmed (YES), the control system switches the address of the inspection operation to the second specification data (step 4). Therefore, the operator can perform maintenance and inspection of the operation of the elevator from the control console connected to the connector 13 by using the address based on the second specification data. If the setting of the second control program cannot be detected in step 1 (NO) and if the completion of the writing of the second specification data is not detected in step 3 (NO), the address is the address of the existing specification data. (Step), the worker checks the operation of the elevator by using the address for the already-specified data as before.

In the first embodiment, the bus line 3 is connected to the terminal equipment on the elevator maintenance management company 21 side via the data transmission unit 8 and the remote maintenance device 7 as in the prior art. Therefore, the operator can check the operating status of the upgraded elevator even in a remote place.

FIG. 6 is a timing chart showing a state of data transmission between the terminal equipment on the side of the elevator maintenance management company 21 and the data transmission section 8, and the remote maintenance device 7, ie, the elevator maintenance management. Company 2
The terminal device on one side becomes the master (main) and performs data communication.

That is, first, the elevator maintenance management company 2
A read command is transmitted from the terminal device on the first side to the data transmission unit 8. When the data transmission unit 8 performs data read transmission of the second specification data or the like to the terminal device side, an ACK
(Acknowledgment character) is transmitted to the terminal device via the remote maintenance device 7. In addition, when read transmission is not performed, N
Transmit AK (negative acknowledgment character).

Then, when the ACK is transmitted from the data transmission unit 8 to the terminal device, the operator next transmits the necessary address designation code and the number of transfer bytes from the terminal device to the data transmission unit 8.
Send to Therefore, the data transmission unit 8 reads data corresponding to the address designation code from the EE-ROM of the second IC 221 (second specification data) and transmits the data to the terminal device.

Similarly, when the terminal device separately writes data into the second specification data storage unit (221), a write command is transmitted first,
After the transmission of the ACK, the data designated by the address is transmitted to the data transmission unit 8, so that the data is written to the second specification data storage unit (221).

In this way, from a terminal device at a remote location,
Data reading from and writing to the second specification data storage unit (221) can also be executed.

In the first embodiment, the description is made such that the second control program (second IC 222) and the second specification data (first IC 221) are replaced and mounted in the program storage unit 4. However, the program storage unit 4
Instead, the specification data storage unit 6 or the data storage unit 5
May be replaced.

As described above, according to the first embodiment, when the IC package 22 is mounted on the substrate 1, the additional program is started, and the first IC 221 of the specification data is started.
The upgrade is automatically performed by rewriting the transmission memory and specification data, eliminating the need for operators to write data from the control console one by one as in the past, making repairs (upgrades) easy and reliable. The elevator can be operated with the stored existing specification data even during the renovation, so that the operating rate of the elevator can be improved.

Next, in the first embodiment, the second control program (the second IC 222) and the second specification data (the first IC 221) are transferred to the existing IC on the substrate 1.
(Program storage unit 4) and the like, but it is described that an external device having only the first and second ICs 221 and 222 is connected to the connector 13 connected to the bus line 3. And repair work of the control system can be performed.

That is, a second embodiment of the elevator control device according to the present invention, in which the connector 13 is connected to an external device, will be described below with reference to a main part circuit diagram of FIG. 7 and a flowchart of FIG.

As shown in FIG. 7, first, an external device 23 to which a second connector 22 a is connected is connected to the connector 13, and a first 1 C (second specification data storage unit) is connected via a buffer 231. 221 and a second IC (second program storage unit) 222 are connected. In addition,
A buffer 231 is connected to the external device 23 so that data transmitted to the bus line 3 does not overflow.

The operation of the elevator in the control system repair in the configuration shown in FIG. 7 will be described with reference to FIG. Although omitted in FIG. 7, in this embodiment, FIG.
The data transmission unit 8 is connected to the elevator maintenance management company 2 via the remote maintenance device 7 and the communication line 20 as in the configuration shown in FIG.
At the same time as being connected to the first terminal device, both the already-specified data and the second specification data are transmitted to the terminal device side. It is also possible to check the operating status of the elevator using the existing data that is not upgraded.

That is, the worker first connects the external device 23 to the connector 13 (step 10).

Next, the external device 23 in step 10
It is determined whether or not the connection is normal (step 11). When the connection is normally made (YES), the program additional setting, the transfer of the specification data, and the version are started by activating the additional program, as in the first embodiment. After the completion of the initial processing for upgrading and adding the program, the address is switched to the upgraded second specification data (step 12). The second specification data after the switching is transmitted to the terminal device (step 13).

If the normal connection of the external device 22 cannot be detected in step 11 (NO), the CPU 2 reads out and starts the already-controlled program in the program storage unit 4 (step 14). Is transmitted to the terminal equipment of the elevator maintenance management company 21 via the remote maintenance device 7 (step 15).

As described above, also in the second embodiment,
During the repair work of the control system, the operator does not need to write the specification data, etc., and can perform maintenance and inspection of the elevator operation by the control program, so the efficiency of the repair work of the control system can be improved. Thus, the operating rate of the elevator can be improved.

In each of the above embodiments, the specification data storage unit 6 and the second specification data storage unit (the first IC 2
21) is described as being composed of an EE-ROM, but the RA backed up by a flash memory or a battery
M may be used.

[0056]

According to the first aspect of the present invention, the conventional specification data and the like are stored as they are, a new second control program is started for the transferred existing specification data, and the specification data is upgraded. Is performed, even if there is a defect in the upgraded second specification data, the CPU controls the operation of the elevator based on the existing specification data, so that the control can be performed without lowering the operation rate of the elevator. System renovation work can be performed efficiently.

According to the second aspect of the present invention, the second specification data can be set to the data write-inhibited state by an external signal. Replacement can be prevented, and data reliability can be improved.

According to the third aspect of the present invention, since the address conversion table is provided, the operator erroneously determines that the operation of the elevator based on the second specification data should be checked based on the existing specification data. Even if the address is specified, the inspection operation automatically switched to the second specification data is performed, so that the inspection of the operation of the elevator based on the second specification data can be easily and reliably performed.

According to the fourth aspect of the present invention, since the second specification data and the second control program are mounted on the external device, there is no need to replace the IC package mounted on the board. It is possible to prevent accidents such as damage to the connection pins or damage to the circuit board when the operator replaces the IC.

According to the fifth aspect of the present invention, the specified data obtained by executing the control program started by the CPU or the second specified data obtained by executing the second control program is maintained via the data transmission unit. Since the information is transmitted to the management terminal device, the worker can grasp the operation status of the elevator even in a remote place, and can efficiently manage the elevator.
