To a common monitoring center via a shared public telephone line, and a remote monitoring system for an elevator that can make a call via a public telephone line between the intercom provided in each elevator car and the monitoring center .
[0002]
[Prior art]
Elevators tend to be installed not only in medium- and high-rise buildings but also in small-scale buildings and private houses as a means of vertical transportation within buildings. Elevators that carry people and cargo must always maintain a safe operating state, and for this purpose, daily maintenance and inspection work is performed by dedicated maintenance personnel.
[0003]
Normal maintenance of elevators is carried out by full-time maintenance staff of elevator maintenance companies, but recently, the operation status of elevators is operated 24 hours a day, 365 days a year via a public line using a remote monitoring system (24 hours a day, all year round) It has come to be monitored in a 24/7 system. For this reason, the operation status of the elevator is always monitored remotely using a remote monitoring system, and only when there is a possibility of abnormality or when periodic inspection is required, a dedicated maintenance staff should go to the elevator installation site (site). It has become a form.
[0004]
This remote monitoring system constantly monitors the operating state of the elevator installed in the building by a remote monitoring device installed in the building where the elevator is installed, and transmits the collected data to the monitoring center of the elevator maintenance company through the public network. To do. An intercom is installed in the elevator car for emergencies. If the elevator stops due to a power failure or the like and the passenger is trapped in the elevator car, the passenger and the elevator maintenance company A call can be made with the monitoring center operator.
[0005]
The monitoring center monitors the data transmitted from a number of elevators, and if any abnormal signs are found or a failure is confirmed, a dedicated maintenance staff rushes to the site to check the abnormalities and take countermeasures. I do.
[0006]
A schematic configuration of such a remote monitoring system is shown in FIG. In the remote monitoring system of FIG. 9, an elevator machine room 1 includes a remote monitoring device 2 that collects state data necessary for monitoring the elevator, and an elevator control device 4 that controls the raising, lowering, and stopping of the elevator car 3. is set up. The remote monitoring device 2 and the elevator control device 4 are connected via a transmission line 5. The elevator car 3 is provided with an emergency call button 34 and an intercom 6 for an emergency. The electrical connection between the elevator controller 4 and the elevator car 3 is made through the tail cord 7, and the communication circuit of the intercom 6 is also connected to the elevator machine room 1 through the tail cord 7.
[0007]
When an abnormal situation occurs in the elevator, the passenger 3A turns on the emergency call button 34 attached to the operation panel in the elevator car, so that the communication circuit is further installed from the elevator machine room 1 to the room of the building manager. Enables a call to the interphone master unit. The intercom 6 is an emergency call device. Therefore, the intercom battery 26 is provided in the elevator machine room 1 so that the intercom 6 can be used even when the power of the elevator power supply is interrupted. As the interphone battery 26, for example, a DC6V or DC24V Ni—Cd battery is used. The intercom 6 is always operated by the power supply sent from the elevator machine room 1, but when a power failure occurs, the interphone battery 26 ensures the operation for about 30 minutes from the occurrence of the power failure.

It is possible to remove the anxiety of the passenger 3A, and to rescue immediately. Pressing the emergency call button 6A in the elevator car 3 leads to the manager in the building, but the intercom 6 can also talk directly to the elevator maintenance company 9 in the event of an elevator failure or power failure. Therefore, the passenger 3A informs the operator of the elevator maintenance company 9 about the situation of the breakdown and the situation of the passenger and requests rescue, or conversely, the elevator maintenance company 9 reports the progress of the rescue to the passenger. It is used to encourage passengers 3A to respond calmly.
[0011]
The second function is to fulfill the preventive maintenance function before the elevator becomes abnormal. The remote monitoring device 2 receives data related to the operation state of the elevator from the elevator control device 4 via the transmission line 5 one by one, and the received operation state data of the elevator is always sent to the elevator maintenance company 9 via the public telephone line 8. Transmit data. Elevator maintenance company 9 can catch any signs of abnormalities from changes in the data sent to it, and check and maintain defective parts before the elevator breaks down and an accident occurs. To be able to
[0012]
The third function is to contribute to shortening the recovery time in the event of an elevator failure. Since the data related to the operation state of the elevator is transmitted to the elevator maintenance company 9 every moment, the elevator maintenance company 9 can accurately determine the state in the event of a failure, and the local response can be performed quickly and in a short time. be able to. As a result, the elevator recovery time can be shortened.
[0013]
FIG. 10 is a block diagram showing a schematic internal configuration of the remote monitoring device 2.

[0017]
On the other hand, in recent years, an increasing number of buildings have a plurality of elevators installed in the same building. In such a case, there is often a method of reducing the cost by sharing one public telephone line 8 with the remote monitoring device 2 of the corner elevator. It is used. Such a system configuration is shown in FIG. FIG. 11 illustrates a case where three sets of remote monitoring devices 2A, 2B, and 2C are provided to monitor three elevators. The remote monitoring devices 2A, 2B, and 2C are respectively provided corresponding to the elevator control devices 4A, 4B, and 4C for each corner elevator, and the public telephone line 8 is shared by these devices. Here, although the public telephone line 8 is connected to the first remote monitoring device 2A, the LINE / PHONE terminal (not shown, but used by a general modem) of the internal telephone line processing unit 11 is used. Prepared for connecting a telephone to a modem) is independent, and the public telephone line 8 is connected to the LINE terminal of the telephone line processing unit 11. In order to share the public telephone line 8 with each remote monitoring device, the PHONE terminal of the remote monitoring device 2A and the LINE terminal of the remote monitoring device 2B are connected by the telephone line 44, and similarly, the PHONE terminal of the remote monitoring device 2B and the remote monitoring are connected. The LINE terminal of the device 2C is connected by the telephone line 45. With this configuration, one public telephone line 8 can be shared by each remote monitoring device 2A, 2B, 2C. Since there is a low possibility that a plurality of remote monitoring devices issue information to the monitoring center 38 at the same time, a system without any problems can be configured by such sharing.
[0018]
By the way, regarding the call from the monitoring center 38 to the remote monitoring device, since a specific remote monitoring device 2 cannot be selected, various proposals have been made to solve it.
[0019]
Japanese Examined Patent Publication No. 6-71291 discloses each remote monitoring device as a method of transmitting data to a plurality of remote monitoring devices 2 sharing the public telephone line 8 from the monitoring center 38 side of the elevator maintenance company 9. 2 is set in advance, and the incoming call stop setting means for stopping the incoming call of the remote monitoring device 2 from the monitoring center 38 side for a certain period of time is used, and a plurality of public telephone lines 8 are shared. Functional means for selecting a desired remote monitoring device 2 from among the remote monitoring devices 2 is described. According to this method, when accessing a device having a lower incoming call rank among a plurality of remote monitoring devices 2 sharing the public telephone line 8 from the monitoring center 38, a device higher than the desired device is accessed. It is possible to communicate with a desired lower-level device only after the incoming call stop setting is sequentially performed and the higher-level device does not receive an incoming call for a certain period of time and then transmits again. In this case, if the incoming order of a desired device is low, it is necessary to perform one incoming call stop setting for all devices higher than that device.
[0020]
Japanese Patent Laid-Open No. 11-232570 adds a local communication function between the remote monitoring devices 2 and stops the incoming call by additionally transmitting the number of the remote monitoring device 2 desired by the monitoring center 38 at the time of the first incoming call. Improvement proposals that can be implemented within two times have been proposed.
[0021]
Further, Japanese Patent Laid-Open No. 11-11815 proposes an improvement plan that enables the remote monitoring device 2 that has detected a failure to receive a call with the highest priority.
[0022]
[Problems to be solved by the invention]
There are various types of elevator failures, ranging from those that are very minor and non-urgent to those that are classified as major and highly urgent, and are particularly anxious and annoying to passengers, such as confinement failures. A major failure is a serious failure that requires urgent action. When a failure occurs, the passenger 36 in the elevator car 3 operates the emergency call button 34 to notify the monitoring center 38 of the elevator maintenance company 9. As a result, a normal response is possible.
[0023]
However, when the passenger 36 in the elevator car 3 wants to obtain additional information from the operator of the monitoring center 38, it is necessary to make a report from the monitoring center 38 to the elevator car 3. When such a situation occurs at the same time in a plurality of remote monitoring apparatuses 2 sharing the public telephone line 8, a remote monitoring apparatus in which a call from the monitoring center 38 of the elevator maintenance company 9 is in charge of the desired elevator There is a drawback in that it takes a considerable amount of time to receive a call at 2.
[0024]
On the other hand, the method of locally providing a communication function between a plurality of remote monitoring devices 2 has improved the above-mentioned problems, but the reliability of communication between the plurality of remote monitoring devices 2A, 2B, 2C becomes a problem. There is an inconvenience.

DETAILED DESCRIPTION OF THE INVENTION
<First Embodiment>
FIG. 1 is a block diagram showing an elevator remote monitoring system according to a first embodiment. The system configuration is as shown in FIG. 11, and the remote monitoring device is as shown in FIG.
[0034]
FIG. 1 shows an internal configuration of a digital circuit unit 10A according to the present invention, which is configured by extracting the digital circuit unit 10 in FIG. Here, it is assumed that three elevators A, B, and C are provided in the same building, and elevator controllers 4A, 4B, and 4C are provided for the respective elevators A, B, and C. Similarly, a remote monitoring device 2A is connected to the elevator control device 4A, a remote monitoring device 2B is connected to the elevator control device 4B, and a remote monitoring device 2C is connected to the elevator control device 4C via the transmission line 5, respectively. To do.
[0035]
The feature of the remote monitoring device 2A including the digital circuit unit 10A is that it can respond only to a call from the monitoring center 38 within a specific response time, and each unit has a different response time. Yes.
[0036]
In the digital circuit section 10A, two data, that is, the number data in the same line as the number machine data, are stored in the EEROM 17A. As the machine data, “00” is set for the remote monitoring device 2A, “01” is set for the remote monitoring device 2B, and “02” is set for the remote monitoring device 2C. As the number data in the same line, “03” is set corresponding to the number of elevators, that is, the number of remote monitoring devices. Each remote monitoring device makes an incoming call at the time allotted in units of one minute based on the number data in the same line as the unit data. That is, the remote monitoring device 2A starts at 00 minutes every hour and makes incoming calls at 03, 06,... 54, 57 minutes. Similarly, the remote monitoring device 2B makes an incoming call at 01, 04, 07,... 55, 58 minutes. The remote monitoring device 2C makes an incoming call at 02, 05, 08, ... 56, 59 minutes. If a call is made from the monitoring center 38 in accordance with this time, the desired remote monitoring device 2 can be quickly selected.
[0037]
FIG. 2 is a flowchart for explaining the operation on the remote monitoring device 2A side in the first embodiment. In step S1, the ringing tone of the telephone from the monitoring center 38 via the public telephone line 8 is detected. This ringing tone is detected by the telephone line processing unit 11 (see FIG. 11), and is read out by the CPU 14, and if it is normal, the incoming call processing (on the public telephone line 8 is on-hook. Is. In step S2, the time data of the calendar IC 18 is read. The calendar IC 18 stores time data of year / month / day / hour / minute / second, but in this embodiment, only the minute data is used. In step S3, it is confirmed based on the data stored in the EEROM 17A whether or not it is a time when the device itself can be received. For example, if the current time is 00 minutes, the remote monitoring device 2A can communicate, so the process proceeds to step S4 and the incoming call control is executed. Similarly, if the current time is 01 minutes, the remote monitoring device 2B performs communication processing.
[0038]
In this embodiment, since the number of elevators is 3, the operator of the monitoring center 38 can communicate by waiting for a maximum of 2 minutes to select the desired remote monitoring device 2. This can be said to be a method that can reliably execute a call in a short time without any error compared to a case where a telephone call is made many times for a call as in the conventional example.
[0039]
A time lag of the calendar IC 18 of the remote monitoring device 2 may also be a problem, but if the time is adjusted during a normal elevator inspection, there will be no major problem.
[0040]
<Second Embodiment>
FIG. 3 shows a second embodiment. The monitoring center 38 in the elevator maintenance company 9 is provided with a plurality of monitoring devices 40A, 40B, and 40C according to the number of elevators to be maintained. Normally, 1500 remote monitoring devices 2 are assigned to each monitoring device 40 in consideration of the load on the public telephone line 8.
[0041]
Different telephone numbers are assigned to the monitoring devices 40A, 40B, and 40C. For example, 5555 is assigned to the monitoring device 40A, 5556 is assigned to the monitoring device 40B, and 5557 is assigned to the monitoring device 40C. The intention of the operator of the monitoring center 38 can be transmitted to the remote monitoring device 2 by using the caller number display function supported by the telephone company in this way. This will be described below.
[0042]
Unlike the conventional example, a caller number display device 41 is installed in the elevator machine room 1, and the caller number is identified via this number notification transmission line 42 (usually controlled by RS232C or USB). Thus, the remote monitoring devices 2D, 2E, and 2F are selected. In this method, only the remote monitoring device 2D selectively responds to a call from the monitoring device 40A, only the monitoring device 2E selectively responds to a call from the monitoring device 40B, and does not respond to a call from the monitoring device 40C. Only the monitoring device 2F selectively responds. Usually, when the common public telephone line 8 is used, the number of units in the same line is 4 or less, so that the system configuration is satisfactory if there are four monitoring devices 40 at most.
[0043]
In this way, the desired monitoring device 2 can be specified by the monitoring device 40 of the monitoring center 38 even on the common public telephone line 8. As a result, even the waiting time required in the first embodiment for selecting a desired car can be made unnecessary.
[0044]
<Third Embodiment>
FIG. 4 shows a remote monitoring system according to the third embodiment.
[0045]
In the first embodiment, since the data of the calendar IC 18 in the remote monitoring device 2 is used, if the remote monitoring devices 2 store different time data, an erroneous operation result may be caused. In order to prevent this, the time data is transmitted as calendar data from the calendar IC 18A of the elevator control device 4 to the RAM 16A included in the digital circuit section of the remote monitoring device 2G via the transmission line 5, and further to other remote monitoring devices 2H, 2H, 2J is also transmitted through lines 46 and 47 for use. In this communication method, time data is added in a normal remote monitoring device using the transmission line 5 and the time data of the elevator control device 4 is taken in the remote monitoring device 2.
[0046]
By doing so, it is possible to prevent malfunctions caused by the remote monitoring devices 2 storing different time data.
[0047]
<Fourth embodiment>
FIG. 5 shows a remote monitoring system according to the fourth embodiment.
[0048]
In the present embodiment, when the public telephone line 8 is required, the elevator normally performs group management control. Elevator group management control is implemented in order to efficiently operate a plurality of elevators as a whole. The elevator group management device 42 has a circuit configuration similar to that of the elevator control device 4, and includes a calendar IC 18B. The elevator group management device 42 is connected to each elevator control device 4A, 4B, 4C via a group management transmission line 43. The remote monitoring devices 2K, 2L, 2M specific to each elevator control device are provided with a RAM 16B for storing calendar data.
[0049]
The time data transmission method is the same as that of the third embodiment, but the time data is taken into the elevator control devices 4A, 4B, 4C from the calendar IC 18B of the elevator group management device 42 via the group management transmission line 43, Thereafter, time data is transmitted by the same means as in the third embodiment. As the group management transmission line 43, Ethernet is usually used.
[0050]
In the first embodiment, since the data of the calendar IC 18 in the remote monitoring device 2 is used, if each remote monitoring device 2 stores different time data, an erroneous result may be caused. In order to prevent this, in this embodiment, time data is transmitted from the elevator group management device 42 to the calendar data register in the RAM 16B of the remote monitoring device 2 and used.
[0051]
Unlike the third embodiment, this embodiment is advantageous in that the time data is collected in the group management device 42, and the time lag is reduced.
[0052]
<Fifth embodiment>
FIG. 6 is a flowchart according to the fifth embodiment.
[0053]
The flowchart of FIG. 6 corresponds to a process in which steps S5 and S6 are added to steps S1 to S4 of the flowchart of the first embodiment shown in FIG. The digital circuit unit 10 has a configuration in which time data for counting timeout is added to the EEROM 17A having the configuration of FIG. The time data is a value slightly deviated for each remote monitoring device 2 in the same line. For example, the time data of the remote monitoring devices 2A, 2B, and 2C are 30 seconds, 40 seconds, and 50 seconds, respectively. This is because simultaneous reception is not performed in the case of a plurality of elevators.
[0054]
In step S5, it is checked whether or not the incoming call control is performed within the predetermined time set as described above. If the incoming call control is not performed even after the predetermined time has passed, the process proceeds to step S6 and the incoming call is received. It shows that the control is forced.
[0055]
The present embodiment provides a solution when the time data that may be a drawback of the first embodiment has a variation among a plurality of remote monitoring devices 2.
[0056]
<Sixth Embodiment>
FIG. 7 is a data transmission transition diagram for explaining the sixth embodiment. This embodiment solves the problem that the remote monitoring device 2 that has received an incoming call in the first embodiment does not know which unit.
[0057]
In response to the call from the monitoring center 38, the remote monitoring device 2 returns data indicating the own machine by a push button signal. For example, if the number data in the EEROM 17A (FIG. 1) is 01, the telephone line processing unit 11 (FIG. 10) sends a push button signal “1”, “2” if 02, and “3” if 03. To the public telephone line 8. In the monitoring center 38, it is judged by an operator or an automatic call receiving device whether or not the push button signal corresponds to the requested machine, and if there is no problem as shown in FIG. If so, perform subsequent call processing. In this way, it is possible to carry out the machine number confirmation requested by the monitoring center 38. If the machines do not match at the monitoring center 38, the system is as shown in FIG. 5B, and the public telephone line 8 is disconnected (off-hook). Thereafter, in the first embodiment, an operation of calling again after a predetermined time has elapsed.
[0058]
As a result, the monitoring center 38 can not only confirm the desired car number, but also has an advantage that the remote monitoring device 2 can recognize that there is a time lag and the destination signal is different.
[0059]
<Seventh embodiment>
FIG. 8 is a data transmission transition diagram for explaining the seventh embodiment. In this embodiment, in the first embodiment, when a time lag occurs in the incoming remote monitoring device 2, it is simply corrected by remote operation.
[0060]
Since the time data is often shifted in units of seconds, for this correction, the CPU 14 of the remote monitoring device 2 sends the second data to the calendar IC 18 by a push button signal (for example, “#”) for adjusting the seconds from the monitoring center 38. Correction is performed.
[0061]
As another embodiment relative to the seventh embodiment, the calendar IC 18 generally has a monthly difference (an error of one month) of about 15 seconds, so that there is generally no problem with correction in units of seconds. It is also possible to make an accurate correction by transmitting.
[0062]
【The invention's effect】
According to the present invention, in a plurality of remote monitoring apparatuses sharing a public telephone line, an inexpensive remote monitoring system that can easily connect to a desired unit and receive a call from the monitoring center by managing the time of the monitoring center. Can be realized.
[0063]
Each remote monitoring device is provided with means for detecting and displaying a call telephone number from the monitoring center, and by determining the call telephone number sent from the monitoring center and displaying the call, control of the desired number is performed. Therefore, it is possible to realize an inexpensive remote monitoring system that can be easily connected to and can receive a call from the monitoring center.
