2. Description of the Related Art Conventionally, in order to monitor a plurality of elevators, an intercom base unit, which is a communication device with the inside of a car, and an elevator control device dedicated to elevator equipment are integrated and a large number of lamps and switches are arranged side by side. The board has been widely adopted.

Japanese Patent Application No. 11-345621 proposes a system in which a group management device for a plurality of elevators also serves as an elevator monitoring control panel.

Japanese Patent Application No. 11-343081 discloses OA
We are proposing a system that monitors and displays the operation of elevators on a personal computer.

Japanese Unexamined Patent Publication No. 7-172713 discloses a data communication means with a remote place via a telephone line, a specification program data storage section for operating a function according to specifications, and control for running control based on specification data. There is proposed an elevator control device including a unit and a program data change control unit that changes specification program data based on data stored in a data buffer.

However, when changing the specifications, it is necessary to suspend all elevators. Alternatively, it is necessary to change the specifications at a time of low usage frequency, and the specification changing work is limited to nighttime or holidays. Therefore, the personal computer in the building cannot be used as the operation specification changing means during the working hours on weekdays from the viewpoint of ensuring safety.

Japanese Patent Laid-Open No. 11-88359 and Japanese Patent Laid-Open No. 11-100179 disclose the status of a service for calling a hall in an elevator control device and a control status signal output to a building network via an elevator network and a router to use the elevator. Is displayed on the display screen of the OA personal computer or building management equipment that is normally used at work, and is used as a call registration display, service level display, or monitoring panel for grasping the elevator congestion status at the office. Shows a system that performs various monitor displays.

On the contrary, an application using an OA personal computer as a data input device for registering the contents to be displayed on the information guide device of the elevator not directly related to the elevator control is also proposed.

Japanese Unexamined Patent Publication No. 11-29263 discloses an elevator control apparatus for executing advance car control by a centralized learning function of passenger generation time for each floor, in which a personal computer is added with a meeting floor and time setting function. Is shown.

Japanese Unexamined Patent Publication No. 8-324900 discloses, as an example of connecting a personal computer to a group management control device, comparing and displaying an operation specification instruction input and service performance such as waiting time before and after a change, and driving by an elevator administrator. It shows how to use a personal computer to support the selection of specifications.

On the other hand, an elevator monitoring control panel equipped with a CRT display and a keyboard as disclosed in Japanese Examined Patent Publication No. 7-80654 and an elevator dedicated monitoring panel using a personal computer that can use a widely used mouse have become popular in recent years. It's going all the way.

On the other hand, in recent years, in order to miniaturize an elevator monitor panel including a lamp, an LED, a waveform changeover switch and the like, a personal computer is often used as a monitor panel.

However, in order to add a new function, it is necessary to discuss the equipment installed in the building, individual piping / wiring, transmission method, etc., such as cooperative control of the elevator equipment and other equipment, remote operation, etc. To add the function of (1) requires a lot of work and cost, which is one of the factors that the system that uses other equipment monitoring devices in the building and the personal computer for the elevator monitoring control does not spread.

FIG. 10 is a block diagram showing the overall construction of a conventional elevator monitoring control system for monitoring three elevators. This conventional system is an elevator control device 11, 1 for three elevators that serve multiple floors.
2 and 13 are provided.

Two hall call registration devices 31, 33 installed on each floor, and arrival guide devices 41, 42, 43 installed on each floor corresponding to each car, elevator control of each elevator. It is connected to the devices 11-13.

In the system of FIG. 10, when the hall call registration device 31 is pushed and a hall call signal is generated, this signal is normally taken into the elevator control device 11, but the elevator control device 11 is controlled due to a failure or the like. When it is impossible, for example, the elevator controller 12 is configured to control.

It is desirable that the landing call registration device installed between the two elevators can be input to the elevator control devices on both sides.

Although not shown in detail, the hall call registration devices 31, 33 and the elevator control devices 11, 12, 13 may be connected by a multiplex transmission line.

In this case, the elevator control device 12 of the elevator which is not the main unit is dedicated to reception for listening to signal transmission between the main unit and the hall call registration device, and when the main unit is powered off, the power supply system It is possible to switch to the own machine, drive the multiplex transmission line in the transmission master station mode in place of the main machine, receive a landing call registration operation signal, etc., and transmit a response lamp lighting signal, etc.

In the system of FIG. 10, for the second car without the main connection of the landing call registration device, direct wiring to the landing call registration device and a data receiving circuit are not provided, and the group control is performed from the elevator control device of each elevator. Add a landing call registration signal to the transmission data sent to the transmission line,
If this is received by each car, the landing call registration can be executed by the second car as well as the first car and the third car.

In this configuration, in the case of an abnormal situation of the group management transmission line, it is possible to adopt a configuration in which the hall call registration control is executed in order to switch to the independent operation and continue the operation. Elevator network transmission line L also used for group management control
Even if an abnormality including a transmission function occurs in the elevator control device of 2 or another elevator, if it is a short time of about 10 seconds,
You can continue to register for landing calls.

In such a situation, whether to drive in response to only a car call according to an instruction from the supervisory control function 21,
If the vehicle is operated in the skip operation mode in which the elevator stops only on the even floors or the odd floors, or if the circulation service operation is performed in response to the landing call, the functional deterioration can be suppressed to a minimum.

Elevator control devices 11, 12, 13;
The elevator monitoring control interface 21, the group management control device 20, and the operation monitor recording device 22 are connected by an elevator transmission network L2.

For the elevator transmission network L2, it is desirable to use a transmission system such as Ethernet, RS-422A, LON Works, and Arcnet that has high reliability and excellent noise resistance. Good.

When the signal transmission system dedicated to elevator control is adopted, the elevator supervisory control unit is provided with an elevator supervisory control function interface device 22 having a dedicated interface function, that is, an adapter for converting into a general-purpose transmission means. It is desirable to connect with the personal computer PC11 that is responsible for this.

If this connection system is adopted, the personal computer originally adopted becomes obsolete, and even if a failure occurs after the same model becomes difficult to obtain, a new model PC can be easily adopted.

In the system of FIG. 10, a personal computer PC11
If the group supervisory control device 20 and the elevator network transmission line L2 operate even if there is a failure in the system, simple registration and sharing control of landing calls, response operation control to registered calls, common reset control after service, etc. Group management control is possible, and the basic function as group management is maintained.

As described above, maintaining the basic function of group management is particularly important in buildings such as hotels where 24 hours a day users are incessant and large-scale buildings.

However, the elevator monitoring control interface 21, the group management control device 20, the operation monitor recording device 2
There is a high possibility that an elevator transmission network L2 connecting between the two will suffer a failure due to electrical noise and cause an elevator system down.

In order to provide the function of calling the VIP elevator with the mobile phone S32 from the inside of the passenger car or the entrance, for example, a communication line is provided between the telephone network system S31 and the elevator control device 11 with VIP operation specifications. It was necessary to add piping and wiring to connect with.

Even in a new building, the meeting is often delayed, which causes a delay in construction.

Using the personal computer PC14 installed in the conference room or secretary room connected to the group management control device 20 by a dedicated transmission line, any elevator from the group management elevators of three can be used as a visitor floor or a large conference end floor. Even if there is a specification such that the personal computer calls and waits, a new transmission line needs to be added to call the VIP specification elevator with a personal computer.

Regarding the simple required specifications for creating a specific landing call from the security system S2 or the information terminal system S41 in the condominium room, direct wiring J21 to J23, J43, J43 for incorporating relay contacts is added to perform a cooperative operation. The configuration that executes control was the mainstream.

In order to construct the above-mentioned facility in the building and the cooperative control system, it is necessary to make a function meeting and a meeting of piping / wiring locations and routes individually, which is difficult to carry out during a busy construction period. .

Furthermore, in order to perform connection and cooperative control with other equipment monitoring devices in the building, such as Ethernet (registered trademark) which has become widespread in recent years, a common transmission line is used between the equipment other than the elevator equipment in the building. There are more and more cases of connecting with.

However, in a system using a general network in a building, various troubles and maintenance work cause the network to stop. Therefore, it is necessary to install elevator control equipment including a fire control operation mode for directly saving lives and an earthquake control operation mode. On the other hand, it cannot be connected as it is. Under these circumstances, conventional contact-passing connections are still widely used.

Therefore, in order to reduce the number of wires from the elevator control panel in the building to the elevator monitoring control panel,
There is an increasing demand for communication wiring or cables instead of direct wiring.

In recent personal computers, not only has the price and processing capacity improved dramatically, but the communication modules have also been enhanced, made more compact, and their power consumption has been significantly improved. Further, the emergency power supply device is also extremely miniaturized.

However, since there is a big problem in reliability and social life that the model soon becomes an old model, the personal computer is an auxiliary device operated by humans such as a maintenance device in the elevator control device and the group management control system. The current situation is that it is only used in certain areas.

When a personal computer is used as part of an elevator monitoring and control system, it is said that a system configuration that does not cause a serious problem even if the personal computer breaks down is required. It was provided.

Japanese Examined Patent Publication No. 7-108749 discloses a connection between an in-building network and a personal computer, which manages in-building utilization status information online, via a in-building communication network.
Information about each building is captured as unique data in the elevator control system via the network, the operation of the elevator is managed according to the predicted traffic demand, and the group management control function that changes and adjusts the optimal elevator selection function is realized. Figure 3 shows an elevator group supervision controller with means.

In this conventional example, information such as OA system information processing, attendance / leaving management, conference room reservation, reception guidance, and cafeteria management is taken into the elevator control system via the building management device and used at a high level to accurately predict traffic demand. It is going to be useful for optimizing the operation control method and improving waiting time.

[0043]

Instead of a complicated system configuration in which various personal computers and dedicated wirings and communication wirings are installed for each use, an exclusive monitor panel for elevators and other systems in the building are provided via a common transmission line. To simplify the system configuration,
Elevator monitoring and control functions by an open function that allows monitoring and operation of elevator equipment, selection of operation specifications, setting and input of display messages to LED indicators built into elevator equipment from other systems in the building It is desired to develop an elevator monitoring and control system that expands the system and increases the degree of freedom.

In that case, the monitoring and control operation by the personal computer used for the elevator exclusive monitoring means are open function, that is, the priority of responsiveness is given to other functions newly pursued for convenience. , It is necessary to improve the stability and durability of the transmission and display functions.

In order to set or operate the operation specifications of the elevator from a plurality of points, it is better to set the priority for each item.

Compared with the monitoring system for elevator equipment that has been operating for more than 25 years, the other equipment in the building is an air conditioning management system, a lighting management system, an information display control system for color liquid crystal devices installed in elevator-related locations,
Facilities such as indoor-installed intelligent terminal systems, security systems, building management systems, etc. have short renewal cycles, and replacement of the intra-building network transmission line connecting these facilities is also required by the elevator-specific monitoring means. Expected to be much shorter than the period.

Even during the construction of other equipment in the building, the monitoring function of the elevator equipment, which saves human lives, cannot be stopped. Therefore, it is necessary to have a system configuration capable of continuing the elevator monitoring control even when updating the building network. It is desirable to be able to minimize the influence on the elevator-dedicated monitoring means and the deterioration of function even if abnormalities or maintenance work occur in a wide variety of building network transmission lines.

The in-building network transmission path is TCP / IP-based transmission using Ethernet for each building to be built, BACnet that establishes a standard interface as a protocol for building facility monitoring, and LO means unique to the transmission means.
There are various types such as Nwaks. The transmission speed is likely to be further increased in the future. In the future, there is a high possibility that the intra-building network transmission consisting of optical transmission lines and wireless centers will appear.

An elevator monitoring control system having a unified transmission line dedicated to monitoring inside elevator facilities, with emphasis on stability and sustainability without being affected by the types and changes of these various network transmission lines in buildings Via, functionally link the elevator control device and various equipment in the building,
There is a demand for an elevator monitoring and control system that can easily connect to different building network transmission lines for each building without affecting the monitoring function of elevator equipment.

In the present embodiment, regarding the first bank and the third bank, which have common specifications for intra-bank transmission and transmission with the elevator monitoring device EM1, it is confirmed that communication from the monitoring monitoring device EM1 is interrupted for a certain period. When the group management control device 2 or the unit control device K31 detects it, the group management control device 2 or the representative elevator control device K31 continues the group management control processing such as the hall call distribution control and the group management transmission within the bank. It is configured to continue or restart the execution of transmission control on the road to improve reliability and maintainability.

Most of the internal processing of the elevator monitor EM1 is usually executed by a microcomputer.

FIG. 7 is a flow chart for explaining the operation of the entire elevator supervisory control system shown in FIG.

The processing explanation contents of each step will be explained by associating each processing block P11 and the like shown in FIG. 1 with the data F11 and the like.

In step 100, the elevator monitoring device E
The transmission data creation units TX11 to TX13 create transmission files whose legends are shown in FIG. 3 or FIG. 6 corresponding to destinations and transmission methods of signals to be transmitted from M1 to each elevator control device K11 and others and the group management control device M1. To do.

In step 101, the communication process with the elevator equipment starts a series of transmission processing in the transmission circuits L11 to L13 of FIG. 1, sends the data created above to the elevator equipment, and receives data creation sections RX11 to RX13. Then, a reception table whose legend is shown in FIG. 2 or 4 is created.

In step 102, the data received in the format shown in FIG. 2 or 4 is rearranged so that it can be easily processed by the received data editing section P11, and the contact state signal fetched from the input circuit I11 is added to add the elevator state data F.

At step 103, the failure detector P22
By using the check data included in the data, each elevator control device K11 to K32, personal computer PC11, PC
The failure of 12, PC14 and each system S11-S41 is detected.

At step 104, VIP operation schedule registration data registered from the OA personal computer PC14 in the secretarial room, the automatic landing call registration command from the telephone network system S31, the personal computer PC11 and the building management system S.
Various schedule control commands such as operation control specification change commands from 11 and the like are created by the command creation unit P21 based on the clock signal and the data of the first or second recording files F21 and F31.

At step 105, the transmission data creating section TX
At 21, the transmission data to the elevator dedicated monitoring means PC11 and the like is created.

At step 106, the transmission circuits L21 and L2
2 communicates with elevator monitoring means PC11, PC12.

At step 107, communication processing with the building equipment by the transmission circuit L31 via the communication conversion device L32 and control signal generation processing by the received command are performed.

At step 108, various building facilities S11
~ S41, PC14 and elevator dedicated monitoring means PC1
The first and second storage files are updated based on the received data from 1 and 12.

In step P106, the failure of the elevator-dedicated monitoring means PC11 and PC12 is diagnosed, and either the reception data creation program RX21 or RX22 of the system that can correctly and continuously operate is selected and used.
Configure so that normal system monitoring can be continued.

In addition, the in-building network transmission line L6,
Individual equipment and systems S22 to S4 connected to the destination
3. The PC 14 is individually diagnosed, and the command from the abnormal system and the past reservation control command are invalidated.

In some cases, the PC 12 of the elevator-dedicated monitoring means B issues a command for the entire open control system,
It is also possible to provide a function such as reservation and display of a failure diagnosis result, and display a corresponding part when a failure occurs and issue a warning to ask for a decision of invalidation.

Further, it is possible to configure the PC 12 or a substitute operation command to be input from the PC 12 in place of the broken open control function.

If a function to organize not only the operation status of many elevator facilities in the building but also the malfunction history and abnormality history inside the elevator facility and display them collectively in bank units is provided, a maintenance company expert will inspect them. Even if the elevator is not installed, it can be judged normally in a short time. The cause such as long waiting can be investigated.

Further, by setting a reservation during the maintenance and inspection from the elevator-dedicated monitoring means, it is possible to avoid issuing an unnecessary alarm.

FIG. 8 is a flow chart for explaining the interface processing procedure by the transmission data creation means TX21 and the reception data creation means RX21, RX22 for transmission between the elevator monitoring device EM1 and the elevator dedicated monitoring means PC11, PC12.

In step 200, the cycle is activated every 100 ms or 1 second.

At step 201, it is judged whether or not the initial transmission with the elevator monitoring device EM1 required when the monitoring person PC11 for elevators using a personal computer or the like stands up in the morning.

If not completed, in step 203, all the monitoring commands stored on the side of the elevator monitoring device EM1 are transmitted to the personal computers PC11 and PC12.

A command for efficiently receiving a set of other building equipment, such as a service floor cut signal, is set in the transmission circuit L31.

In order to efficiently transmit the set of stored data of the operation contents stored on the personal computer side, it is set in the next divided transmission data transmission circuits L21 to L31.

At step 203, the operation file F24, which is the elevator state data of all the vehicles until the previous day, is automatically transmitted.

Here, in FIG. 1, the transmission data creation TX2
1 is shared by one, but it may be provided individually. In this case, the initial transmission of the operation file F24 may be performed only to the PC 12, and the monitoring work by the elevator-dedicated monitoring means PC11 can be started earlier by that amount.

When the initial transmission is completed, in step 202, change data priority transmission data of elevator state data is created. When the number of changed data is less than the predetermined number, the amount of regularly transmitted data is increased.

In step 204, the transmission abnormality with the elevator-dedicated monitoring means PC11 is detected by the communication activated periodically. In addition, using the system abnormality detection check data for the elevator control device side of FIG. 4 as it is, not only the communication abnormality with the elevator dedicated monitoring means PC11 but also whether or not the internal application processing is operating are checked to check the system function. If there is no abnormality in step S207, the elevator status signal required for the operation monitor display screen including the car position display is preferentially transmitted in step 207.

The transmission format is not limited to the transmission format with the elevator installation shown in FIG. 4 or 6. In the received data file, the displayed screen number or the elevator number list displayed by the operation monitor may be added to the received data.

In order to monitor the open control command status with the elevator-dedicated monitoring means PC11 and PC12, the reception data format shown in FIG.
1, need to send to PC12.

Specifically, in step 208, the group management operation control specification changes and elevator operation commands fetched from the shared network in the building are organized in bank units into the reception format shown in FIG.
Send to 2.

In some cases, in order to display the group management operation control specifications, parking, flooding operation commands, etc., which are changed by commands from the group management control device M1 or the like from the maintenance device or the remote maintenance center, on the monitor means PC11 dedicated to the elevator. In addition, it is necessary to receive from the elevator equipment side in the table of FIG. 6 which is a data format originally transmitted from the elevator dedicated monitoring means PC11 and the monitoring board EM1.

In step 209, the operation storage file F, which is a temporary storage file for recording the operation data for one hour or several days.
The contents such as 24 are transmitted to the elevator dedicated monitoring means PC12 and PC11 in response to a request command from the elevator dedicated monitoring means PC12 or PC11. of course,
It is also possible to send only to the PC 12.

If it is determined in step 204 that the operation is normal, in step 262, an elevator operation storage command is transmitted, an operation command is received, and in step 264, a control operation command command is received.

At step 266, the control operation command / monitoring operation command including the abnormality of the elevator dedicated monitoring means PC11 is transmitted to all the elevators, and the transmission process of FIG. 4 and the reception process of FIG. carry out.

At step 210, the instruction for invalidating the storage of the operation command and the service disconnection signal from the facility system in the building is issued to the elevator monitor means PC12 or PC11.
It is judged whether or not it has been sent from, and if it has been sent, it is invalidated including the past command.

Therefore, even if an abnormality occurs on the other equipment side, the operation of the elevator equipment can be continued or restarted at the discretion of the administrator.

At step 220, it is judged whether there is a continuous transmission abnormality with the elevator monitoring unit PC12 of the backup system.

If it is determined in step 230 that both elevator-dedicated monitoring means PC11, PC12 are in continuous failure and it is determined that the invalid switch is newly turned on, in step 240, the elevator-dedicated monitoring means PC11, P12 are monitored.
The creation of the control command based on the contents of the first storage means storing the control command from C12 is invalidated, and the alarm buzzer is activated.

However, when it can be determined that the equipment in the other building is normal, the preparation of the control command by the second storage means is continued and the transmission to the corresponding elevator equipment is continued.

When any storage means is declared invalid, the control command data shown in FIG. 6 is cleared or the default control command data is set and transmitted to the machine.

Alternatively, if it is left for one hour or more, instead of the disabling switch, the command from the elevator dedicated monitoring means PC11, 12 stored in the first storage means is automatically invalidated, and the elevator equipment is Change the control command signal in the direction in which can be operated.

In contrast to this situation, if one of them is moving or if there is a short-term abnormality, in step 235, the abnormality operation record and alarm are not executed, and a monitoring operation command is created by the final received signal and operation is performed. continue.

As a result, it is possible to prevent the inconvenience such as a temporary transmission abnormality or a command for canceling the parking instruction being erroneously issued when the control switching maintenance inspection is performed from the personal computer PC11 to the PC12.

FIG. 6 shows another example of the transmission format sent from the machine side to the personal computer PC11 of the monitoring device or the elevator dedicated monitoring means A. Compared with the format for the conventional monitoring panel shown in FIG. To support control and operation monitor recording and display, the types of signals have been significantly increased.

Further, as shown in the relative address, for a signal that changes depending on the number of floors, it is unified, for example, on 64 floors, that is, 8 bytes, and care should be taken not to have a different transmission format for each elevator specification. is doing.

With respect to the transmission format (FIG. 3) from the conventional personal computer PC11 of the elevator dedicated monitoring means A or the elevator monitoring panel to the elevator installation, in the example of FIG. 6, operation control and operation specification change can be made open. As described above, the types of control command signals are significantly increased.

FIG. 9 shows an elevator dedicated monitoring means PC11.
5 is a flowchart for explaining the processing procedure of the monitoring display and the monitoring operation performed in the personal computer.

Step 300 is periodically activated every 300 ms or 1 second.

At step 301, the elevator status data F11, the operation record file F24, the first and second record files F21 and F31, the failure detection information and the like are transmitted to the transmission circuit L21 in the elevator monitor EM1 and the transmission described in FIG. By means of the means, the change amount of the designated high speed request data is preferentially taken in from the elevator monitor EM1 selectively and periodically.

Step 301 may have a configuration of full-duplex transmission executed as a set with the transmission process of step 308.

Search various data files on the transmitting side,
Since the changed data is transmitted preferentially, high responsiveness can be obtained even with relatively low transmission.

At step 302, the mouse and keyboard of the elevator-dedicated monitoring means PC11 are used to execute a selection operation of an elevator monitoring display screen, parking, a service cut command, and the like.

At step 303, the display of the selected monitor screen is updated based on the received data relating to the selected monitor display screen.

There is also a method of reducing the amount of data transmitted to the transmission circuit L21 by creating a command for requesting a data read request related to the selected monitor display screen in step 301.

Collect main data regularly and periodically,
In step 304, operation data using the received signal of the elevator status data F11 is created and recorded, and is automatically written and recorded in the hard disk inside the personal computer with a file name for each day.

It is determined at night or when the transmission is quiet, and in such a situation, a request for receiving the operation record file F24 created on the side of the elevator monitoring device EM1 is made, and it is received collectively.
It can also be configured to be stored.

The incidental processing such as the operation record can be mainly carried out on the personal computer PC12 side which is the sub-elevation dedicated monitoring section B.

For example, when the number of passengers waiting for a waiting time for a long hall is determined to be less than a predetermined reference time or when the average waiting time of average passengers for a predetermined period exceeds the reference waiting time, Display the date and time when the judgment value is exceeded and its related data.

At step 305, a periodical fetch of failure-related signals, switch operations, failure diagnosis data, etc. is requested, and a failure history file is updated and a warning or alarm is given by voice or the like.

Transmission circuit L21, reception data creation processing RX
22, first storage file F21, failure detection process P2
2, by using the designated signal creation process P21, the drive circuit O1
1, the buzzer BZ1 can be smoothed.

At step 306, the command recording process from the facility in the building, the contradiction diagnosis and the alarm process are executed.

Invalidation processing is performed for each control command item of the elevator facility based on the command from the facility in the building or the stored information of the command according to the command from the elevator-dedicated monitoring means PC12 (or PC11).

The invalidation processing is automatically performed also by the contradiction diagnosis judgment of the command from each building equipment (S11 to PC14) and the abnormality judgment of the transmission via the common transmission line L6 of the building equipment,
At this time, the monitor means personal computer PC12 dedicated to the elevator
(Or, the control command input function from the PC 11 is used or disabled.

In this way, it is possible to input frequently-operated operation commands such as VIP operation commands and conference end special operation commands from two locations at all times, and prevent confusion such as the problem of location of responsibility and other facilities. When is broken,
The merit of being able to act on behalf of the lift-dedicated monitoring unit is created.

At step 307, abnormality diagnosis processing is performed based on the elevator state data. If an abnormality is detected, an alarm signal and an alarm buzzer BZ1 drive command are created and output.

Here, on the side of the elevator monitoring means PC11, it is informed that there is an abnormality by means of a display or voice, and the date and content of the abnormality are also stored in the alarm history file.
The function of determining an abnormality and driving the buzzer may be executed by the failure detection unit P22 as shown in FIG.

At step 308, the types of operation signal data and reception request data are transmitted to the elevator monitoring device EM1. Even if the amount of data to be transmitted is large, since it is a signal manually operated by a human, the amount of data that changes per unit time is extremely small.Therefore, the method of transmitting only the data related to the changed or operated signal is transmitted. It is extremely advantageous quantitatively.

The car position data, which changes frequently with respect to many elevators, can be transmitted at high speed. However, when such a change transmission method is adopted, the personal computer PC1
1. When the PC 12 is started up, it is necessary to search and send data other than the data $ 00 and send a command to replace the contents of the first recording file F21 stored in the elevator monitoring device EM1.

When replaced with a new personal computer, there is no past transmission data file, so conversely, the first recording file F21 stored extremely in the elevator monitoring device EM1.
It is necessary to search for data other than the data $ 00 in the contents of the above, and perform a decision process for the request command to be transmitted to the transmission personal computer PC11 or PC12.

In the processing procedure of FIG. 9, since the group management control process is executed by using a commercially available general-purpose personal computer, which is increasingly sophisticated and inexpensive, it is necessary to check the function of the group management control process.
Work such as adjustment, maintenance, and improvement becomes extremely efficient.

[0218] Also, after starting operation, modification work to the latest newly developed group management control system software,
It becomes very easy to switch to customized group management software according to the operating status.

Further, remote inspection from the maintenance company and software improvement are possible. The maintenance work of the elevator group management control device cannot be stylized like a failure response of general equipment or a failure occurrence prevention activity. Depending on conditions such as building environment, elevator specifications, number of vehicles, traffic demand, etc., it is necessary to consider the various matters and modify the specifications while contacting the customer side administrator.

Diagnosis of the elevator group management function requires a high degree of knowledge and abundant experience. If a personal computer is used for the diagnosis of the elevator group management function, a dedicated group diagnosis can be performed from a maintenance service center of a maintenance company located in a remote place, which leads to improvement of maintenance service.

Conventionally, maintenance work can be frequently and timely performed by switching to group management control software according to changes in the number of users and the usage situation from the time of building completion, which was often left unattended.

With respect to complaints and improvement requests from tenants and the like to building managers, remote diagnosis enables prompt support.

[0223] Regardless of the manufacturer of the elevator, the unattended / unmanned night security system is operated via this elevator monitoring control system.
Monitoring work can be performed on behalf of automated buildings.

Group management control processing If the personal computer is also used as an elevator monitoring device, the installation space can be reduced, the wiring work at the site can be simplified, and maintenance costs such as personal computer replacement can be suppressed.

If a personal computer that executes the group management control function and a personal computer that executes the elevator monitoring control function are used together, conventionally, the group management control device and the elevator monitoring control device separately transmit and receive using a plurality of networks. Communication can be integrated.

That is, it is possible to reduce the circuit scale of each elevator control device by combining a monitor panel transmission line for displaying the machine control status and control operation command signals and the group management operation control signal transmission line into one transmission line.

There are many overlapping signals in both transmission data. If a dual-purpose personal computer is used, the group management control transmission and the elevator monitoring control transmission can be shared, and software related to communication and the group management control device can be integrated with the monitoring device normally installed in the elevator management personnel room. There is no need to go to the rooftop machine room, which is inconvenient and dangerous to come and go.

There is a great merit that the operation of the elevator can be confirmed, adjusted and inspected from a safe place such as a management room or a disaster prevention center in the building, and general inspection of the elevator control device and various on-site adjustments of the elevator can be performed.

In particular, in a building where there is no elevator machine room, which has been increasing recently, the following advantages can be obtained by integrating the group supervisory control device with the elevator monitoring control device. (1) If the group management control device is installed in the elevator hoistway,
It is necessary to develop, manufacture, and install wiring for a thin group control board, but if it is integrated with the monitoring device and installed in the manager's room, the work and cost for development will be unnecessary. (2) Compared with the case where a group supervisory control device is installed in the elevator hoistway, inspection and maintenance work are easier, which is advantageous in terms of safety. (3) Compared to the case where a group supervisory control device is installed in the elevator hoistway, there is less conflict with building construction work and the construction period is shortened.

[0230]
