  The present invention relates to an elevator remote monitoring device that transmits elevator operation status information during elevator operation to a remote monitoring center via a communication line.

  The elevator remote monitoring system includes a monitoring device that captures image information of a monitoring camera and an audio signal of an interphone, and a remote monitoring center that acquires information sent from these monitoring devices and centrally monitors the information. The communication means between the monitoring device and the remote monitoring center is a general subscriber telephone line or a digital communication line (hereinafter referred to as ISDN (Integrated Services Digital Network)). Image information and audio signals are transmitted.

  Conventionally, when information to be transmitted from a monitoring device is transmitted to a remote monitoring center via a public line, the public line is provided with two channels or one channel.

  When two channels are provided on the public line, one channel is for transmission of audio signals output from the intercom installed in the elevator car, and the other channel is a surveillance camera installed in the elevator car etc. It is used for transmission of image information.

Further, when one channel is provided on the public line, it is used for voice transmission and information transmission while switching alternately (Patent Document 1).
JP 2001-97645 A (see FIG. 1)

  By the way, in the elevator remote monitoring system, it is very important for monitoring the elevator to collect not only the audio signal output from the intercom and the image information of the monitoring camera but also various operation status information during the elevator operation. Requirements.

  However, the technique of Patent Document 1 is not a system that monitors information related to elevator operation, but is a monitoring system that exclusively uses humans, and cannot accurately grasp the operation status of the elevator.

  Further, in the technology of Patent Document 1, since two channels are provided in a general subscriber telephone line, information can be transmitted reliably, but when a specific monitoring device transmits information, the remote monitoring center side The two lines are occupied. As a result, when a wide-area disaster or the like occurs, if information is intensively transmitted from each monitoring device, a state in which many monitoring devices cannot be connected to the remote monitoring center occurs. Further, since it is analog communication, the communication speed is relatively low, and there is a problem that it takes time to transmit information when a large amount of information such as urgent information or image information is transmitted.

  In addition, when a general subscriber telephone line is provided with one channel, it has the same problems as described above, and it is also used by switching between voice transmission and information transmission alternately. hard.

  On the other hand, when a digital communication line is used, it is necessary to make a direct call between the passenger using the intercom in the car and the operator of the remote monitoring center, but to connect the intercom and the surveillance camera to the monitoring device side. TA (terminal adapter) / DSU (termination unit), means for separating analog signals and digital signals in the digital communication line network of the communication carrier, means for converting to analog signals on the remote monitoring center side Etc., and the configuration and signal processing are very complicated.

  In any case, when a wide-area disaster occurs, reports from each monitoring device are concentrated, and the reception line of the remote monitoring center becomes congested for a long time, so that necessary information can be transmitted quickly and reliably. Disappear.

  The present invention has been made in view of the above circumstances, eliminates congestion of the communication line by efficiently using the communication line while taking advantage of the characteristics of the information to be transmitted, and provides general information relating to elevator operation quickly, and An object of the present invention is to provide an elevator remote monitoring device that reliably transmits data to a remote monitoring center.

  In order to solve the above-described problems, the present invention provides an elevator remote monitoring device that acquires various operation status information of an elevator and transmits the information to a remote monitoring center, the first being connected to the remote monitoring center. A communication line having the communication means and the second communication means, information discriminating means for discriminating the importance of information from various operation status information of the elevator, and the operation discriminated by the information discriminating means as being less important A transmission method determining means for determining status information as a transmission method by the first communication means, and determining the operation status information determined to be highly important as a transmission method by the second communication means; Based on the transmission method determined by the method determining means, the first communication unit that transmits the large-capacity operation status information determined to be low in importance via the first communication means and the importance is determined to be high. It has been fast operation status information via the second communication unit, and a configuration in which a second communication part for reliably transmitted.

  The present invention also relates to an elevator remote monitoring device that acquires various operation status information of an elevator and transmits it to a remote monitoring center, wherein the first communication means and the second communication device are connected to the remote monitoring center. A communication line having the communication means, information determination means for determining the importance of information from the various operation status information of the elevator, and a communication state for confirming communication states of the first communication means and the second communication means Based on the detection result of the detection means and the communication state detection means, when both the first communication means and the second communication means are in a transmittable state, the information determination means determines that the importance is low. A transmission method determining means for determining operation status information as a transmission method by the first communication means, and determining operation status information determined to be highly important as a transmission method by the second communication means; Based on the transmission method determined by the transmission method determining means, the first communication unit for transmitting the large-capacity operation status information determined to be low in importance through the first communication means and the importance level It is the structure provided with the 2nd communication part which transmits the operation condition information determined to be high through the said 2nd communication means at high speed and reliably.

  The first communication unit is, for example, a packet communication unit capable of transmitting a large amount of data, and the second communication unit is configured by, for example, a PIAFS communication unit capable of reliable and high-speed transmission.

  Further, as the transmission method determining means, when the communication state detecting means detects that any one of the first communication means and the second communication means cannot communicate, it is possible to communicate with the other communication means. It is determined that the transmission is performed by the communication means, and the operation status information determined by the information determination means can be transmitted, so that the emergency information can be quickly transmitted.

  Further, as the transmission method determination means, when transmission method determination information passing through the communication line is received from the remote monitoring center, the transmission method determination means replaces the output of the information determination means and the communication state detection means.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall configuration diagram showing an embodiment of a remote monitoring system including an elevator remote monitoring device according to the present invention.

  The elevator remote monitoring system includes a remote monitoring device 2 that captures various information relating to elevator operation (hereinafter referred to as operation status information) from the elevator control device 1, and collects elevator operation status information over a wide area. A remote monitoring center 3 that monitors the operation state of the elevator is connected via a communication line having a PHS (Personal Handyphone System) line network 4 as a first communication means and a packet communication network 5 as a second communication means. ing.

  The elevator control device 1 is composed of a microcomputer, and functionally includes an operation control unit 11, an operation management unit 12, and a failure information detection circuit 13 that execute elevator operation control according to a sequence program.

  The operation management unit 12 captures and records various operation status information from the elevator, and records, for example, a sudden stop position or a stop position shift of a certain stop floor during the elevator operation and records it. An error code part 12a for recording, a trace data part 12b for recording elevator operation history information, a maintenance data part 12c for recording information necessary for maintenance such as the number of times of elevator operation and the number of times of door opening and closing, and the like.

  The failure information detection circuit 13 includes a switch that detects a slightly opened state when the car door and the landing door are closed, a switch that detects an overshoot of the top floor and the bottom floor of the car, and other switches that detect various dangerous states. Thus, when failure is detected by each switch, predetermined failure information which is a kind of elevator operation status information is sent to the remote monitoring device 2.

  The remote monitoring device 2 includes an operation information input unit 21, a failure information input unit 22, an input information determination unit 23, a communication state detection unit 24, a transmission method determination unit 25, a PIAFS (PHS Internet Access Forum Standard) communication unit 26, and packet communication. A portion 27 is provided.

  The operation information input unit 21 is connected to the operation management unit 12 of the elevator control device 1 and sets an error code unit 12a, a trace data unit 12b, and a maintenance data unit 12c for each predetermined cycle (for example, weekly, monthly). The operation status information recorded in the respective sections 12a to 12c is taken in, or particularly necessary information, for example, the error code of the error code part 12a is taken in a week unit, and the elevator operation of the other trace data part 12b is performed. The history information or the like is fetched at a monthly cycle and sent to the input information determination unit 23. Further, although not shown, the operation information input unit 21 may receive information recorded in the operation management unit 12 in response to an information collection instruction from outside at an arbitrary time if necessary.

  In addition, the system which reads out required operation condition information from the operation management part 12 side automatically for every predetermined period, and inputs it into the operation information input / output part 21 may be used. Therefore, since the information captured by the operation information input unit 21 is, for example, information for one week or one month, it can be said that the amount of data is very large but the information is relatively urgent.

  The failure information input unit 22 is connected to the failure information detection circuit 13 of the elevator control device 1, receives predetermined failure information output from the failure information detection circuit 13, and sends it to the input information determination unit 23. The failure information is very urgent information.

  The input information discrimination unit 23 discriminates the data amount and importance of the operation status information received from the operation information input unit 21 and the failure information input unit 22. The input information discriminating unit 23 discriminates that the operation status information sent from the operation information input / output unit 21 has a large amount of data and is less important, but the fault information received from the fault information input unit 22 After determining that the data amount is small but the importance is high, the information of the determination result is added to the operation status information received from each information input unit 21, 22 and sent to the transmission method determination unit 25.

  The communication state detection unit 24 transmits transmissions of the communication line networks 5 and 4 from the communication confirmation 5a of the packet communication network 5 periodically performed by the packet communication unit 27 and the communication confirmation 4a performed by the PIAFS communication unit 26 with the PHS line network 4. Check availability status.

  The transmission method determination unit 25 determines a PHS data transmission method or a packet transmission method based on the determination result of the input information determination unit 23 and the confirmation result of the communication state detection unit 24.

  The transmission method determination unit 25 passes the operation status information to be transmitted to the PIAFS communication unit 26 when it is determined as the PHS data transmission method, and the operation status information to be transmitted when it is determined as the packet transmission method. It is passed to the packet communication unit 27.

  Here, the PHS data transmission method automatically dials the remote monitoring center 3 as a transmission destination, transmits the failure information to the remote monitoring center 3 after completely receiving the incoming response, and when there is no incoming response. This is a system in which redialing is performed again and failure information is reliably transmitted to the remote monitoring center 3 after confirming the incoming call response. Therefore, when there is no incoming response from the transmission destination, information cannot be transmitted, but there is an advantage that a response from the remote monitoring center 3 that is the other party can be reliably received. For this reason, it can be said that it is most suitable for a method for transmitting information on the urgency or importance of information transmission.

  On the other hand, the packet transmission method is a transmission method in which a remote monitoring center 3 as a transmission destination is automatically dialed and then generated and transmitted as a packet regardless of whether there is an incoming call response. Therefore, since the information is transmitted even when there is no incoming response from the transmission destination, there is an advantage that the information can be transmitted even when there is no incoming response from the remote monitoring center 3 as the transmission destination. For this reason, it is effective for the system which transmits the operation condition information etc. of an elevator with low urgency.

  The PIAFS communication unit 26 automatically dials the remote monitoring center 3 as a transmission destination in accordance with the PHS data communication protocol, and when there is an incoming call response, the operation status information is transmitted via the PHS network 4 to the remote monitoring center 3. Transmit to. Note that PIAFS uses a PHS data transmission system, and can usually be transmitted at high speed to a destination via the PHS line network 4 through the same route as a general telephone line network. It is also possible to transmit from the PHS network 4 through ISDN.

  The packet communication unit 27 automatically dials the remote monitoring center 3 as the transmission destination, but generates a packet and operation status information via the packet communication network 5 such as a dedicated network regardless of whether there is an incoming call response. Transmit to the remote monitoring center 3.

  Although not specifically shown in the remote monitoring device 2, when transmitting an audio signal input from an interphone installed in a car or the like to the remote monitoring center 3, the remote monitoring center directly uses the PIAFS communication unit 26. 3 to send. At this time, the audio signal may pass through the input information determination unit 23 and the transmission method determination unit 25, but the transmission method by the PIAFS communication unit 26 is preferentially determined.

  The remote monitoring center 3 is managed by an elevator maintenance company or the like, monitors the operation state of the elevator over a wide area, and provides maintenance services such as dispatching maintenance personnel to the site where the elevator is installed in the event of an abnormality.

  The remote monitoring center 3 includes a packet receiving device 31 and a PIAFS receiving device 32, and a database 34 and a monitoring control console 35 are connected via a network 33. As shown in FIG. 2, the monitoring control console 35 includes a monitoring control processing unit 351, a control instruction information input unit 352, a speaker 353, an interphone 354, a display unit 355, and the like that are configured by a CPU.

  When the monitoring control processing unit 351 determines the reception information content determination unit 35A that determines the operation status information received by the packet reception device 31 and the PIAFS reception device 32, and the operation status information that is less urgent from the reception information content. An information storage means 35B for storing in the database 34 and an emergency output storage means 35C for displaying on the display unit 355 and storing in the database 34 when it is determined that the operation status information is highly urgent from the received information contents are provided. .

  Next, the operation of the elevator remote monitoring system configured as described above will be described with reference to FIG.

  In the elevator control device 1, the operation control unit 11 controls the operation of the elevator according to a predetermined sequence program based on the car call or the hall call. The operation management unit 12 of the elevator control device 1 is divided into error data corresponding to items that are determined as problems in advance during normal operation of the elevator, elevator operation history information, data necessary for maintenance and maintenance work, etc. It records in the code part 12a, the trace data part 12b, the maintenance data part 12c, etc. As described above, the elevator operation status information is transmitted by the remote monitoring center 3 on a weekly or monthly basis. As a result, the operation status information of this type of elevator is relatively large capacity data, but is less urgent.

  The failure information input unit 22 in the remote monitoring device 2 determines whether failure information has been input (S1). Here, when it is determined that failure information has not been input, the operation information input unit 21 determines whether an error has occurred in the operation management unit 12 based on an information collection instruction input at predetermined intervals or at an arbitrary time from the outside. It is determined whether the operation status information recorded in the code portion 12a, the trace data portion 12b, and the maintenance data portion 12c is all or selectively taken in a predetermined order, or whether the operation status information is input based on the information collection instruction ( S2).

  Here, when the operation information input unit 21 takes in the operation status information at every predetermined period or determines that the operation status information is input, the operation information input unit 21 sends the operation status information to the input information determination unit 23.

  When receiving the operation status information from the operation information input unit 21, the input information determination unit 23 determines that the urgency is low (packet communication is selected) for information transmission (S 3), and information on the determination result is included in the operation status information. To the transmission method determination unit 25 (S4).

  On the other hand, the communication state detection unit 24 takes in the communication confirmation 5a periodically performed by the packet communication unit 27 with the packet communication network 5 and the communication confirmation 4a performed by the PIAFS communication unit 26 with the PHS line network 4. Then, whether transmission to the packet communication network 5 and the PHS line network 4 is confirmed (S5) is provided to the transmission method determination unit 25.

  The transmission method determination unit 25 determines from the output of the communication state detection unit 24 whether, for example, both packet communication as the first communication means and PIAFS communication as the second communication means are communicable (S6). If it is determined that both can communicate, the operation status information is passed to the packet communication unit 27 based on the determination result of the input information determination unit 23. The packet communication unit 27 generates packet operation status information in a packet regardless of whether there is an incoming call response, and transmits it to the remote monitoring center 3 via the packet communication network 5 (S7).

  On the other hand, when any abnormality occurs in the elevator, the failure information detection circuit 13 detects which part of the elevator is defective, and the failure information is input to the failure information input unit 22 via the failure information input unit 22 of the remote monitoring device 2. 23. As described above, the input information determination unit 23 determines that there is failure information input (S1) and passes it to the input information determination unit 23. The failure information includes failure elevator and failure site identification information.

  Based on the failure information input from the failure information input unit 22, the input information determination unit 23 determines that the urgency of information transmission or the importance of information is high (selects PIAFS communication) (S 3). A determination result is attached and transferred to the transmission method determination unit 25 (S4).

  Incidentally, when it is determined that the importance level is high from the determination result of the input information determination unit 23, it is necessary to reliably transmit it to the remote monitoring center 3. Therefore, the data for PHS (corresponding to the C-mail transmission of the mobile phone) Determine the transmission method.

  Here, based on the confirmation output from the communication state detection unit 24 described above (S5), the transmission method determination unit 25 passes the failure information to the PIAFS communication unit 26 when determining that the PIAFS communication is possible. The PIAFS communication unit 26 automatically dials the remote monitoring center 3 as the transmission destination, transmits the failure information to the remote monitoring center 3 after completely receiving the incoming response, and redials again when there is no incoming response. The incoming call response is confirmed, and the failure information is reliably transmitted to the remote monitoring center 3 (S7).

  Then, after the transmission of the operation status information in step S7, it is determined whether or not to continue the process (S8). If it is determined that the process is to be continued, the process proceeds to step S1, and if it is determined that the process is not to be continued. Ends.

  Steps S9 and S10 will be described later in “Other Embodiments” (2).

  The remote monitoring center 3 receives the operation status information transmitted from the packet communication unit 28 by the packet reception device 31 and temporarily stores it, and the failure information transmitted from the PIAFS communication unit 26 by the PIAFS reception device 32. Receive and store temporarily.

  Here, the monitoring control console 35 in the remote monitoring center 3 is urgent from the operation status information received by the packet receiving device 31 and the PIAFS receiving device 32 by the reception information content determination means 35A of the monitoring control processing unit 351 constituted by the CPU. Judgment of gender. Here, the information storage unit 35B stores the information from the received information content determination unit 35A in the database 34 via the network 33 if the information is less urgent, such as an error code, operation history information, maintenance data. In addition, the emergency information output storage unit 35C of the monitoring control processing unit 351 determines the identification information (building) added to the failure information in the case of information determined to be highly urgent such as failure information as a result of the operation status information. Based on the name, failure part, and failure content), which building or the like has a failure is displayed on the display unit 355, and if it is an audio signal, it is output from the intercom 353 and stored in the database 34.

  Therefore, according to the embodiment as described above, the transmission method determination unit 25 performs transmission based on the importance of the operation status information determined by the input information determination unit 23 and the transmission availability information from the communication state detection unit 24. Determine the method. That is, the transmission method determination unit 25 determines the packet communication method when the amount of information data is large and the importance is low, transmits the operation status information to the remote monitoring center 3, and the operation status with high importance. In the case of information, it is transmitted to the remote monitoring center 3 using PIAFS communication. Therefore, it is possible to eliminate congestion of the communication line by efficiently using the communication line while making use of the characteristics of the operation state information, and necessary operation state information can be transmitted to the remote monitoring center 3 quickly and reliably.

(Other embodiments)
(1) In the above embodiment, the transmission method determination unit 25 determines the transmission method based on the determination result of the input information determination unit 23 and the communication line state of the communication state detection unit 24. The transmission method may be determined according to only the determination result of the unit 23, that is, the size of the data capacity and the importance of the information.

  In general, when highly important operation status information (failure information) occurs, transmission from the determination result of the input information determination unit 23 is considered that it is extremely rare that the PHS network 4 is accidentally disabled. Even if the method is determined, highly important information can be reliably transmitted to the remote monitoring center 3 with a very high probability.

(2) In the above embodiment, it is assumed that both the packet communication network 5 and the PHS line network 4 are in a transmittable state, and the remote monitoring center 2 to the remote monitoring center 3 according to the determination result of the communication state detecting unit 24. This is an example of transmitting information.

  However, the input information discriminating unit 23 is based on the failure information input from the failure information input unit 22, and the operation status information is highly important, and the PHS line network 4 is requested even though the selection of the PIAFS communication is requested. Some abnormality may have occurred.

  Therefore, as shown in FIG. 3, when the transmission method determination unit 25 receives the communication confirmation 4a for disabling the transmission of the PIAFS communication from the communication state detection unit 24 despite the high importance information, A communicable packet communication unit 27 is selected and, for example, failure information is passed to the packet communication unit 27 (S9).

  When receiving the failure information from the transmission method determination unit 25, the packet communication unit 27 generates a packet regardless of whether there is an incoming call response, and transmits the packet to the remote monitoring center 3 via the packet communication network 5 (S10).

  According to this embodiment, when some abnormality occurs in the PHS line network 4, when highly important information enters, the packet communication unit 27, which is another communication network, is automatically selected, and the packet Since it is transmitted to the remote monitoring center 3 via the communication network 5, emergency information with a relatively small amount of information can be reliably transmitted to the remote monitoring center 3 relatively early. As a result, the remote monitoring center 3 can quickly take an abnormality recovery procedure when the elevator is abnormal.

(3) In the above embodiment, the transmission method determination unit 25 in the remote monitoring device 2 determines the transmission method based on the determination result of the input information determination unit 23 and the state of the communication line of the communication state detection unit 24, and the transmission The information to be transmitted is transmitted to the remote monitoring center 3. For example, when the monitoring person inputs a transmission method determination instruction from the monitoring control console 35, the remote monitoring center 3 passes the communication path 4 b of the PHS network 4, for example. The configuration may be such that the transmission method determination information is notified to the remote monitoring device 2.

  When the transmission method determination unit 25 in the remote monitoring device 2 receives the transmission method determination information via the communication path 4b of the PHS network 4 and the PIAFS communication unit 26, the transmission method determination unit 25 sets the transmission method determination information in a storage unit (not shown). . Thereafter, when receiving the information to be transmitted from the input information discriminating unit 23, the transmission method determining unit 25 transmits the information to be transmitted to the remote monitoring center 3 by the transmission method determined by the transmission method determining information that has already been set.

  According to this embodiment, when a wide-area disaster or the like occurs, the number of receptions at the remote monitoring center 3 may increase rapidly, and the communication line may become congested. At this time, if it is possible to arbitrarily determine the communication network from the remote monitoring center 3 to the remote monitoring device 2, for example, by determining the PIAFS communication, high-speed transmission is always possible and reception efficiency can be improved. Communication line congestion can be suppressed.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
