Description

The present invention relates to an elevator control system that writes data in a nonvolatile memory of a hall control device that is replaced when a defective hall control device is replaced, and a method for exchanging the hall control device.

Conventionally, in a hall control device having a non-volatile memory, a problem that occurs when an equipment breaks down and is replaced with a new hall control device is that data stored in the non-volatile memory of the hall control device is new. It is to write to the non-volatile memory of the hall control device. In the hall control device, the data stored in the non-volatile memory is, for example, font data when display characters displayed on the hall indicator are special, and is often data unique to the elevator.
Even in such a case, since it is necessary to quickly restore the elevator, conventionally, the non-volatile memory of the hall control device is attached using an IC socket or the like. Either remove the non-volatile memory from the device and install it on a new hall control device, or use a data writing tool such as a personal computer to write the data in the non-volatile memory to the non-volatile memory of the new hall control device. I was doing.

In Patent Document 1, in the method of removing the specification data ROM from the failed board and attaching it to the new replacement board, even if the microprocessor of the failed board and the microprocessor of the replacement board are different, the failed board An elevator control device is shown which is made available by exchanging data in the specification data ROM of a new microprocessor with a new microprocessor.

Japanese Patent Laid-Open No. 10-245165 (pages 3 to 5, FIG. 1)

If a non-volatile memory is attached with an IC socket and a failure occurs, the non-volatile memory is removed from the failed hall control device and attached to a new hall control device. Since only a shape that can be attached with an IC socket can be used, there has been a problem in reducing the size and thickness of the hall control device.
In addition, when the nonvolatile memory itself is broken, the nonvolatile memory itself is newly arranged at the factory, and the elevator restoration may not be able to be performed immediately.
In addition, in the method of writing data in the nonvolatile memory to the nonvolatile memory of the new hall control device using the data writing tool, there are problems such as preparation of a rewriting tool and complicated writing work. was there.

Further, in the method described in Patent Document 1, since the specification data ROM of the failed board is removed and used, it is impossible to cope with the case where the specification data ROM itself is broken.

The present invention has been made to solve the above-described problems. When a failure occurs, data is transmitted from another identical hall control device to the nonvolatile memory of the newly replaced hall control device, and the failure occurs. An object of the present invention is to obtain an elevator control system and a method for exchanging the hall control device thereof that make it easier to restore the time and eliminate the need to replace the nonvolatile memory itself.

A slave station data transmission control unit for transmitting the contents of the nonvolatile memory of the own device to another hall control device via the data transmission path disconnected from the transmission side of the master station data transmission control unit, and a setting switch Depending on the data rewrite mode setting by the slave station, the slave station data transmission control unit can transmit data to other hall control devices via the data transmission path disconnected from the transmission side of the master station data transmission control unit. It is composed of a data transmission control unit and a transmission line switching device for switching the connection between the data transmission lines,
When this failed first hall controller is replaced due to a failure of the first hall controller,
In this exchanged first hall control device, the contents of the non-failed second hall control device's non-volatile memory are transferred to the master station data transmission control unit by the slave station data transmission control device of the second hall control device. The slave station data transmission control device of the first hall control device transmits its own data according to the contents of the non-volatile memory sent from the second hall control device. The nonvolatile memory is rewritten.

As described above, the present invention controls a plurality of hall control devices that are installed in an elevator hall and control hall buttons and hall indicators using data stored in a nonvolatile memory, respectively, and operation of the elevator. In the elevator control system constituted by the elevator control device connected to the hall control device via the data transmission path and performing data transmission with the hall control device,

The slave station data transmission control device of the first hall control device transmits its own data according to the contents of the non-volatile memory sent from the second hall control device. Because the non-volatile memory is rewritten, when the hall control device fails, data can be automatically sent from the other hall control device to the non-volatile memory of the newly replaced hall control device. Since the work can be simplified and the nonvolatile memory itself does not need to be replaced, a package product that can be soldered by surface mounting can be used, and the hall control device can be made smaller and thinner.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing an entire elevator control system according to Embodiment 1 of the present invention.
In FIG. 1, an elevator control device 1 includes an elevator control unit 2 that controls the overall operation of the elevator, a master station data transmission control unit 3 that performs data transmission between the landing control devices 8 a and 8 b, and a data transmission path. The transmission / reception driver 4 is connected to 6a and 6b and transmits / receives data from the master station data transmission control unit 3 and the switching device 5 for setting the data rewriting mode of the hall control device.
The elevator control device 1 transmits various control signals to the elevator control devices 8a and 8b installed in the elevator hall using the data transmission paths 6a and 6b in accordance with the operation state of the elevator.
The transmission / reception driver 4 has a function of disconnecting the transmission driver from the data transmission path 6a in accordance with a signal from the master station data transmission control unit 3, and the switching device 5 sets the data rewriting mode of the hall control device ( In the first procedure), a data rewrite mode command is transmitted to the master station data transmission control unit 3 via the elevator control unit 2.
Based on the data rewrite mode command, the master station data transmission control unit 3 stops the operation of transmitting various control signals according to the operation state of the elevator and disconnects the transmission driver from the data transmission path 6a (second). Procedure).

The landing control devices 8a and 8b are installed in the elevator halls on the Nth and Mth floors to control devices such as indicators and landing buttons. In fact, a similar hall control device is installed for the elevator floor.
These hall control devices 8a and 8b transmit data to and from the elevator control device 1, and display indicators 14a and 14b, hall buttons 15a and 15b, and hall key switches 16.
slave station data transmission control units 9a and 9b for controlling operations of a and 16b, transmission / reception drivers 12a and 12b, and setting switch 1 for setting the floor setting of the slave stations and various operation modes
1a, 11b, rewritable non-volatile memories 13a, 13b for storing character font data for the indicator indicators 14a, 14b, data transmission paths 6a, 6b and data transmission paths 6a, 6b. It comprises transmission path switching devices 17a and 17b that switch connections with transmission / reception drivers 12a and 12b that transmit and receive data.

In the hall control devices 8a and 8b, the slave station data transmission control units 9a and 9b periodically check the setting contents of the setting switches 11a and 11b. Further, it periodically checks whether there is data transmitted from the elevator control device 1.
The slave station data transmission control units 9a and 9b confirm whether or not the setting contents by the setting switches 11a and 11b are in the data rewriting mode when the data transmitted from the elevator control device 1 is not available for a certain period. If the mode is set, a process of changing the control operation and transmitting the data in the nonvolatile memory to another hall control device is executed. At this time, the slave station data transmission control units 9a and 9b of the hall control devices 8a and 8b that are not set in the data rewrite mode receive the data in the nonvolatile memory and rewrite the data in the nonvolatile memory to the received data. Execute.

Next, a method for rewriting data in the nonvolatile memory of the hall control device according to the present invention,
A description will be given with reference to FIGS.
FIG. 2 is a flowchart showing an operation process of the elevator control device in the data rewriting mode of the hall control device according to the first embodiment of the present invention.
FIG. 3 is a flowchart showing an operation process of the hall control device in the data rewriting mode according to the first embodiment of the present invention.
For example, in FIG. 1, since the M floor hall control device has failed, a new hall control device 8b is provided.
Consider a case in which the (first landing control device) is attached to the Mth floor and the data in the nonvolatile memory of the new landing control device 8b is rewritten from the Nth floor landing control device 8a (second landing control device). Naturally, the data is not yet correctly stored in the nonvolatile memory 13b of the new hall control device 8b.
First, the operator replaces the malfunctioning hall control device on the M floor with a new hall control device 8b.
Next, when the elevator control device 1 is set to the data rewriting mode of the hall control device by the switching device 5, the transmission processing to the hall control device is stopped according to the flowchart of FIG.

Next, an operation process of the elevator control device will be described based on FIG.
The elevator control unit 2 checks the mode switching input from the switching device 5 (step S
1) When switched to the data rewrite mode of the hall control device, a local data rewrite request command ON (data rewrite mode command) is output to the master station data transmission control unit 3 (step S2). In step S1, when the mode is switched to the normal mode that is not the data rewrite mode of the hall control device, a local data rewrite request command OFF (data rewrite mode command release) is output to the master station data transmission control unit 3 (step S1). S3).
The master station data transmission control unit 3 determines whether or not the local data rewrite request command is on (step S4). If it is on, the transmission process from the master station data transmission control unit 3 to the hall control device is stopped ( Step S5). If it is not ON in step S4, normal transmission processing to the hall control device is performed (step S6).

Next, the setting switch 11a of the Nth floor hall control device 8a is changed to the data rewrite mode setting (third procedure).
Then, the slave station data transmission control unit 9a of the hall control device 8a performs processing according to FIG.
The presence / absence of transmission data from the master station is confirmed (step S11), and if not, it is determined whether or not the data rewrite mode is set (step S12). When the data rewrite mode is set, a switching signal is output to the transmission path switching device 17a, the data transmission path is switched (step S13), and the data transmission path is transferred from the Nth floor to the Mth floor landing controller 8b. Data can be transmitted via 6a.
After switching the data transmission path, the slave station data transmission control unit 9a outputs the data read from the nonvolatile memory 13a to the data transmission path 6a according to a predetermined data transmission procedure (step S14) (fourth) Procedure). The slave station data transmission control unit 9a, when the data has been correctly transmitted (Step S15), displays on the indicator display 14a that the data has been normally completed (Step S16).

If not completed normally (step S15), the data is re-output to the data transmission path 6a in step S14. Even if this is repeated within a certain time (step S17).
) If the data transmission cannot be completed normally, the slave station data transmission control unit 9a displays on the indicator display 14a that the data transmission has not been completed normally (step S18). In this case, as a means for informing whether the data transmission is normally completed or failed, the indicator display 1
In addition to 4a, it is also possible to notify the worker in the same manner, for example, by turning on / flashing a response lamp of a hall button or sounding a sounding buzzer.
Further, as a method for determining whether or not the data transmission is normally completed, the slave station data transmission control unit 9a receives the transmitted data via the reception driver of the transmission / reception driver 12a, so that the transmission data is data. It can be determined whether the data has been correctly output to the transmission path 6a.
Furthermore, when data is transmitted, the answerback signal is reliably received from the M floor hall control device 8b via the data transmission path, the transmission path switching device 17a, and the reception driver of the transmission / reception driver 12a. It is also possible to determine whether the M floor hall control device 8b has received data.

When the data rewriting is completed (step S19), the operator returns the setting switch 11a of the Nth floor landing control device 8a from the setting of the data rewriting mode to the original setting for the elevator operation (step S19). The N-th floor slave station data transmission control 9a outputs a switching signal to the transmission path switching device 17a, switches the data transmission path and disconnects the connection between the landing control devices, and the original elevator control device 1. Switching to connection only (step S20).
Finally, when the operator cancels the data rewriting mode of the hall control device by the switching device 5 of the elevator control device 1, various control signals are transmitted as data in accordance with the operation state of the elevator in normal operation (step S22). Thus, a series of rewriting of data in the nonvolatile memory is completed.

In step S11, there is no transmission data from the master station, and step S12
When the data rewrite mode is not set (fifth procedure), the reception side hall control device performs an operation of receiving data in the nonvolatile memory (step S21), and the slave station data transmission control. The unit rewrites the nonvolatile memory of its own device with the received data (sixth procedure).

According to the first embodiment, by configuring as described above, it is not necessary to remove the nonvolatile memory itself when replacing the hall control device, and a new one is automatically added to the nonvolatile memory of the hall control device. Data can be transmitted from the same hall control device.
This makes it easier to recover from a failure and eliminates the need to replace the non-volatile memory itself, allowing the use of package products that can be soldered by surface mounting, enabling a smaller and thinner landing control device. It becomes.
