JP 2003-212447 A

  The above-described remote monitoring system has a configuration in which an abnormality signal is sent from each elevator to the monitoring center when an abnormality occurs in the device. For this reason, even if there is a sign of abnormality in the equipment, the sign may be missed, and the maintenance staff always goes to the work site.

  Normally, maintenance personnel perform daily maintenance work according to a predetermined patrol schedule, so that when such a device abnormality occurs, it may be difficult for the maintenance personnel to rush to the site. In addition, even if it can be rushed to the site, the patrol schedule will be temporarily interrupted, making it difficult to manage the day's schedule, and the patrol schedule for the following day must be re-assembled.

  Therefore, an object of the present invention is to provide a function variable type remote monitoring system and a remote monitoring method capable of maintaining a predetermined traveling schedule of maintenance personnel as much as possible.

  The present invention relates to an elevator control device that controls the operation of an elevator, a remote monitoring device that transmits information on the elevator control device to a remote monitoring center, and an elevator diagnosis according to purpose for the remote monitoring device. A function variable type remote monitoring system including a program and a diagnosis instruction device that transmits an execution operation control signal of the elevator diagnosis program based on an external request.

  Further, the present invention controls the operation of the elevator by the elevator controller, and executes the elevator diagnostic program for each purpose transmitted from the remote monitoring center to the remote monitoring device and the elevator diagnostic program based on an instruction from the outside. The elevator control device information is obtained from the operation control signal and transmitted to the remote monitoring center.

  According to the present invention, it is possible to maintain a predetermined maintenance staff's patrol schedule.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing the overall configuration of a variable function remote monitoring system according to an embodiment of the present invention.

  In this system, an elevator 11 as an elevator to be monitored is connected to a monitoring center (remote monitoring center) 30 via a communication network 13. As the communication network 13, a telephone line, the Internet, or the like is used, but the communication form is not particularly limited.

  The monitoring center 30 remotely monitors the operation state of the elevator 11 via the communication network 13. In the example of FIG. 1, only one elevator 11 is illustrated, but actually, various elevators installed in each building are connected to the monitoring center 30 via the communication network 13. The monitoring center 30 constantly monitors the operation state of these elevators as monitoring targets.

  The elevator 11 includes a control panel (elevator control device) 21 and a monitoring device (hyperopia monitoring device) 22. The control panel 21 is for controlling the operation of the elevator 11 and is constituted by a computer equipped with a CPU, ROM, RAM and the like.

  The hoisting machine 24 is driven by a control signal output from the control panel 21. As the hoisting machine 24 is driven, the car 26 and the counterweight 27 move up and down in the hoistway through the rope 25 wound around the sheave of the hoisting machine 24.

  The car 26 is provided with an operation panel 28 having various operation buttons, a load sensor 29 for detecting the load on the car 26, and the like. These signals are sent to the control panel 21 via a transmission cable (not shown).

  The operation operation of the elevator by the control panel 21 is constantly monitored by the monitoring device 22, and various signals indicating the operation state are taken from the control panel 21 and transmitted to the monitoring center 30.

  FIG. 2 is a block diagram showing a functional configuration of the monitoring device 22.

  The monitoring device 22 is provided with a monitoring unit 31 and a communication terminal 32. The monitoring unit 31 transmits and receives signals to and from the control panel 21 to monitor control signals from sensors provided at various locations of the elevator 11. A signal from the monitoring unit 31 is sent to the communication network 13 via the communication terminal 32. Signals and commands sent from the monitoring center 30 via the communication network 13 are taken into the monitoring unit 31 via the communication terminal 32.

  On the other hand, a program storage unit 33 is provided in the monitoring unit 31. The program storage unit 33 receives “elevator diagnosis program” and “program execution operation signal” via the communication terminal 32. When receiving the “elevator diagnosis program”, the program storage unit 33 installs the program in the work area, and then waits for the “program execution operation signal” to be input. When a “program execution operation signal” is received, the program is “executed” or “stopped” and further “program uninstall” is performed according to the type of the signal.

  These operations in the monitoring unit 31 are appropriately executed by a CPU (not shown) provided in the monitoring unit 31.

  The measurement table 34 stores various data necessary for the processing operation of the monitoring unit 31. Specifically, the measurement target set by the monitoring center 30 and the reference data of the measurement target are stored.

  FIG. 3 shows an example of diagnosis contents by the elevator diagnosis program stored in the program storage unit 33.

  Here, “riding comfort” and “rope life” are shown as examples of measurement objects. When diagnosing “ride”, the vibration of the car is measured using the output signal of the load sensor 29 attached to the car 26 or other sensor signals. In this case, since the current vibration state of the car can be grasped by comparison with the vibration waveform in a state where the car 26 is operating normally, this is diagnosed using a method such as wavelet conversion. can do.

  In diagnosis of the “rope life”, for example, an output signal of a magnetic flux density distribution around the rope is used by a rope tester (not shown) to measure the state of the strands constituting the rope. Then, by comparing with the measurement result of the past magnetic flux density distribution of the rope, it is possible to grasp the time-dependent change (breaking etc.) of the wire, and therefore it is possible to estimate the rope replacement time.

  These reference data are stored in the measurement table 34 described above, and are appropriately read according to the operation of the elevator diagnosis program installed in the program storage unit 33 and used for calculation. Of course, these reference data can be configured to be supplied from the monitoring center 30 as necessary.

  On the other hand, a diagnosis instruction device 35 is provided on the monitoring center 30 side, and exchanges signals with the monitoring device 22 and remotely executes a diagnosis work by the monitoring device 22. Further, the computer terminal 36 and the transmission / reception station 37 are connected to the diagnosis instruction device 35, and a control signal to be transmitted from the diagnosis instruction device 35 to the monitoring device 22 according to an instruction from them, that is, an execution operation control signal of the elevator diagnosis program is selected. .

  A command can be sent to the diagnostic instruction device 35 via the transmission / reception station 37 by operating a portable terminal 38 (for example, a cellular phone or a mobile computer) carried by the maintenance staff during maintenance inspection.

  In such a configuration, a plurality of elevator diagnosis programs (for example, the above-mentioned “ride comfort” are stored in the diagnosis instruction device 35 (storage area not shown) of the monitoring center 30 in order to perform detailed monitoring according to the request of the property. ”And“ Rope life ”). In performing remote diagnosis, a specific elevator diagnosis program is transmitted in advance to the monitoring device 22 and installed in the program storage unit 33. Of course, if necessary, a plurality of elevator diagnosis programs may be transmitted and installed.

  When the maintenance staff inspects the property, the elevator diagnosis program installed in advance is executed before the inspection. Specifically, the maintenance staff transmits a selection signal for the elevator diagnosis program to be executed and an “execution start” signal, which is one of the execution operation control signals, to the diagnosis instruction device 35 using the portable terminal 38. To do. Upon receiving this, the diagnostic instruction device 35 instructs the execution of a predetermined elevator diagnosis program installed in the program storage unit 33 in the monitoring device 22. The elevator diagnosis program executed in the monitoring unit 31 calculates various sensor signals of the elevator 11 taken into the control panel 21 and transmits the diagnosis results to the diagnosis instruction device 35. The diagnosis result is sent from the transmission / reception station 37 to the portable terminal 38.

  In this way, the maintenance staff can refer to the diagnosis result in advance before performing the maintenance and inspection of the elevator 11, so that it is possible to quickly grasp, for example, the replacement timing of parts and the like. Specifically, maintenance personnel can arrange spare parts in advance before going to the site, prepare maintenance tools to be brought to the site, or assign maintenance personnel with specific maintenance skills to the traveling schedule. .

  Then, the maintenance staff who has obtained the necessary diagnosis result transmits an “execution stop” signal, which is one of the execution operation control signals, using the portable terminal 38. As a result, the elevator diagnosis program executed by the monitoring unit 31 is stopped, and the remote diagnosis ends. Information indicating that the program has been stopped is sent to the monitoring center 30 and confirmed by the portable terminal 38 of the maintenance staff by transfer from the diagnosis instruction device 35.

  Even during such a series of operations of the elevator diagnosis program, normal remote monitoring, that is, the operation of transmitting the output signal of the control panel 21 to the monitoring center 30 is continuously performed. Thereby, for example, when an earthquake occurs during diagnosis or when confinement occurs, a device abnormality is immediately detected, and the monitoring center 30 can receive an emergency signal.

  Also, when it is no longer necessary to re-execute the elevator diagnostic program, or when installing a new upgraded elevator diagnostic program, the current elevator diagnostic program is uninstalled. When the diagnosis instruction device 35 transmits an “uninstall” signal, which is one of the execution operation control signals, the CPU in the monitoring unit 31 deletes the program. Information indicating that the program has been deleted is sent to the monitoring center 30.

  Similarly, the elevator diagnosis program to be executed and the execution operation control signal can be selected from the computer terminal 36. The diagnosis result can be referred to by the computer terminal 36. Therefore, instead of the maintenance staff using the portable terminal 38, the terminal operator (operator) of the monitoring center 30 can give the diagnosis instruction.

  Further, the same instruction can be given to the diagnosis instruction device 35 by operating the computer terminal 39 installed outside the monitoring center 30. In this case, it is assumed that the computer terminal 39 is installed in a sales office of an elevator maintenance company. It is possible to give various instructions via the computer terminal 39 before the maintenance staff leaves the sales office to start the daily maintenance inspection or after returning to the sales office after completing the maintenance inspection. Become.

  In this way, by providing the program storage unit 33 in the property monitoring device 22 for the elevator 11 to be monitored, for example, “Riding comfort” for the A property, “Rope life” for the B property, etc. In addition, even if the maintenance staff does not go to the site to collect the data of the part that particularly requires monitoring depending on the property, it can be easily obtained through automatic diagnosis by an instruction from the monitoring center 30 side. Thereby, for example, it is possible to quickly grasp and cope with the parts replacement time, maintenance check time, and the like.

  Then, before the maintenance staff goes to the site, replacement parts can be arranged in advance, maintenance tools to be brought to the site can be prepared, or maintenance staff having specific maintenance skills can be assigned to the traveling schedule. For this reason, it is possible to assemble a maintenance schedule for maintenance personnel without waste and to easily maintain a predetermined tour schedule. This contributes to an improvement in work efficiency for maintenance personnel in charge of a plurality of sites.

  In FIG. 3, the case where “riding comfort” and “rope life” are set as measurement objects has been described as an example, but the same applies to cases where other measurement objects are set. For example, set various measurement targets that can be diagnosed based on the output signals of various sensors, such as “brake performance”, “sheave wear”, “lights out of car”, “door open / closed state”, “battery life”, etc. Can do.

  In addition, this invention is not limited to the said embodiment as it is, It can implement in various deformation | transformation in the range which does not deviate from the summary.
