Description

  The present invention relates to an automatic failure notification device for an elevator that is used in, for example, a home elevator and reports a failure to a monitoring center using a telephone line.

  A failure occurring in the elevator may cause a personal accident such as a passenger confinement failure, so it needs to be dealt with promptly. Conventional automatic failure notification devices for elevators report failure information detected by an elevator controller to the monitoring center using a telephone line.

Conventionally, for example, an apparatus described in Patent Document 1 has been proposed as means for reporting an elevator failure to the monitoring center.
JP-A-8-282931

  The elevator remote monitoring device described in Patent Document 1 sends an elevator management number / failure content to a monitoring center device via a low-speed communication unit / telephone line when a failure is detected, and is requested from a remote failure diagnosis device. If there is, a large amount of data necessary for investigating the cause of the failure is transmitted via the high-speed communication unit / telephone line.

  As described above, the failure automatic notification device using the conventional telephone line including the device described in Patent Document 1 transmits the elevator management number (report source information) and the failure content by a signal when the failure is detected. The equipment on both the automatic notification device side and the monitoring center side is large and requires expensive equipment.

  In addition, since a telephone line with a low communication speed is used, it takes time to send and receive signals, which causes an increase in telephone charges.

  In addition, since the alarm operation is performed every time a failure signal is input, if a failure signal is continuously input from the elevator, the alarm operation is repeated many times, It occupied the telephone line and caused communication costs to increase.

  The present invention has been made in view of the above points, and its purpose is to provide failure notification with simple equipment and a short communication time, and to avoid unnecessary notification operation and to establish a line by a specific transmission source. An object of the present invention is to provide an automatic failure notification device for an elevator which can avoid the occupation.

And automatic reporting means for performing a reporting operation.

  More specifically, the elevator controller as the elevator control means determines the content of the failure of the elevator, and sends a corresponding failure classification signal to the simple automatic notification device as the automatic notification means. In response to this, the simple automatic notification device calls the telephone (calling destination) having the telephone number corresponding to the inputted failure classification signal on the monitoring center side as the monitoring means.

  On the monitoring center side, the contents (classification) of the failure can be easily grasped by the difference in the destinations of the plurality of telephones, and the caller can be easily identified by using the number display function of the telephones. it can.

  In addition, the simple automatic notification device prohibits a notification operation for a predetermined time after completion of the notification operation.

In addition, priorities are set for the contents of the failure of the elevator, and the simple automatic notification device is configured to provide a failure classification signal corresponding to a failure content having a high priority, for example, “passenger confinement failure” during the prohibition period of the notification operation. Is input, the notification operation prohibition is canceled and the notification operation is performed.

  More specifically, the elevator controller as the elevator control means determines the content of the failure of the elevator, and sends a corresponding failure classification signal to the simple automatic notification device as the automatic notification means. In response, the simple automatic notification device calls one telephone (reporting destination) on the monitoring center side as monitoring means, and sends a tone signal corresponding to the failure classification signal.

  On the monitoring center side, the contents (classification) of the failure can be easily grasped by distinguishing the tone signal, and the sender can be easily identified by using the number display function of the telephone.

According to a second aspect of the present invention, the monitoring center telephone includes a plurality of telephones having different telephone numbers set in accordance with the contents of the failure, and the simple automatic notification device receives the tone signal as the input signal. The failure classification signal is transmitted to a telephone set in the monitoring center corresponding to the failure classification signal.
(3) A third invention for solving the above-described problem is an elevator control that judges the content of a failure that has occurred in the elevator and outputs a failure classification signal corresponding to the failure content and an elevator state signal corresponding to the state of the elevator. Means, a monitoring means having a plurality of telephones with different telephone numbers set in accordance with the content of the failure, a failure classification signal and an elevator state signal are input from the elevator control means, and the failure classification signal corresponds to the failure classification signal It is characterized by comprising automatic notification means for calling a telephone of the monitoring means to perform a notification operation and sending a tone signal corresponding to the elevator status signal.

  More specifically, the elevator controller as the elevator control means determines the content of the elevator failure, and the failure classification signal corresponding to this and the elevator status signal corresponding to the elevator state are simply automatic notification as the automatic notification means. Send to device. In response to this, the simple automatic notification device makes a call to a telephone number (report destination) corresponding to the inputted failure classification signal on the monitoring center side as a monitoring means, and also supports the elevator status signal. Send the tone signal.

  On the monitoring center side, the contents (classification) of the failure can be easily grasped by the difference in the destinations of the plurality of telephones, and the caller can be easily identified by using the number display function of the telephones. It is possible to identify and grasp the state of the elevator.

  In addition, the simple automatic notification device prohibits a notification operation for a predetermined time after completion of the notification operation.

  Further, priorities are set for the contents of the failure of the elevator, and the simple automatic notification device provides a failure classification signal corresponding to a failure content having a high priority, for example, “passenger confinement failure” during the prohibition period of the notification operation. Is input, the notification operation prohibition is canceled and the notification operation is performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the following embodiments.

  FIG. 1 shows a basic configuration of the present invention, and 11 is an elevator controller (elevator control means of the present invention) installed on a car of an elevator car 10. The elevator controller 11 controls the operation of the elevator, determines the content (classification) of a failure that has occurred in the elevator, and issues a failure classification signal (contact signal) corresponding to the failure content.

  Further, the elevator controller 11 not only issues the failure classification signal, but also determines the state of the elevator, as will be described later, and also issues an elevator state signal (contact signal) corresponding to the state.

  Reference numeral 12 denotes a simple automatic notification device (automatic notification means of the present invention) connected to the elevator controller 11 and the telephone line 13. The simple automatic notification device 12 inputs the failure classification signal and the elevator state signal from the elevator controller 11, and calls the monitoring center 14 (the monitoring means of the present invention) corresponding to the failure classification and the elevator state. A notification is made by sending a tone signal corresponding to the failure classification and the elevator state to the monitoring center 14.

  First, as a first embodiment, as shown in FIG. 2, a plurality of telephones 14a with different telephone numbers having a number display function corresponding to the failure content input from the elevator controller 11 in the monitoring center 14 are shown. 14b, 14c... Are installed. 2 that are the same as those in FIG. 1 are denoted by the same reference numerals.

  The simple automatic notification device 12 simply calls the dial destination (the telephones 14a, 14b, 14c,... Of the monitoring center 14) corresponding to the contact signal (the signal corresponding to the failure content) input from the elevator controller 11. A notification operation is performed.

  On the monitoring center 14 side, the content of failure (classification of failure) is specified based on the difference in the destination, and the transmission source (the failure elevator where the elevator controller 11 is installed) is specified by the number display function of the incoming phone.

  As a second embodiment, as shown in FIG. 3, a single telephone 24 having a number display function is installed in the monitoring center 14, and the simple automatic notification device 12 is connected to the elevator controller 11. A contact signal corresponding to the failure content is received and dialed to the telephone 24 of the monitoring center 14, and a tone signal corresponding to the contact signal (tone signal corresponding to the failure content) is transmitted. 3, the same parts as those in FIG. 1 are denoted by the same reference numerals.

  On the monitoring center 14 side, the failure content (classification of failure) is specified by a tone sound that is heard when the telephone 24 is picked up, and the caller (failed elevator where the elevator controller 11 is installed) is identified by the number display function. Is identified. According to the embodiment shown in FIG. 3, one telephone line may be prepared on the monitoring center 14 side.

  Further, as a third embodiment, a call is made to a notification destination (a plurality of telephones having different telephone numbers) corresponding to a failure content (failure classification), and a tone signal according to the failure content (failure classification). Is sent out.

  That is, in the configuration of FIG. 2, the simple automatic notification device 12 makes a call to a dial destination (telephones 14 a, 14 b, 14 c...) Corresponding to the contact signal input from the elevator controller 11 and a tone signal corresponding to the failure content. Is sent out.

  On the monitoring center 14 side, the receiver of the incoming telephone is picked up, the tone signal is heard and the failure classification is specified, and the transmission source (the failure occurrence elevator where the elevator controller 11 is installed) is specified by the number display function. .

  In the first embodiment (FIG. 2), when the handset is picked up at the monitoring center 14, because of a silent telephone state, whether a telephone call has actually occurred due to a failure or is a wrong dial from the device? It is not possible to distinguish whether it is a wrong call from a place other than the device installation location. In the second embodiment (FIG. 2), since the tone signal is only discriminated by the human ear, there is a possibility that the tone sound may be missed or mistaken. However, in the third embodiment, These disadvantages can be compensated.

  In addition, as a fourth embodiment example, a configuration for sending a tone signal corresponding to the state of the elevator from the simple automatic notification 12 is added to the configuration of the third embodiment example. That is, as shown in FIG. 4, the elevator controller 11 outputs a failure classification signal corresponding to the failure content and an elevator state signal corresponding to the elevator state to the simple automatic notification device 12 as a contact signal. The simple automatic notification device 12 makes a call to a notification destination (telephones 14a, 14b, 14c... Of the monitoring center 14) according to the classification of the failure, and sends a tone signal corresponding to the state of the elevator when connected. This makes it possible to grasp the general elevator state in addition to the failure classification. The elevator controller 11 and the simple automatic notification device 12 are provided with a microcomputer (not shown) for performing various processes.

  Regarding the classification of the failure, it is effective to consider the difference in response at the monitoring center 14 such as “passenger confinement failure”, “functional failure”, “inspection test report”, and the like.

  As for the state of the elevator, for example, “level stop”, “floor stop”, “other state”, etc., as a response at the monitoring center 14, whether the customer can safely get off when the door is opened, etc. It is effective to consider the difference in correspondence.

  Examples of the tone signal (“pip, pop, pap” dial tone when a number is dialed on a push line, and a different sound is assigned to each number) are, for example, “89898989898989”, If the sound and pose settings are devised, such as “5-5-5-5-5-5-5-5” and “456-456-456-456”, the discrimination is easy.

  FIG. 5 shows an example of a processing flow of the elevator controller 11 and the simple automatic notification device 12 in the second to fourth embodiments. In FIG. 5, when a failure occurs, in step S1, the elevator controller 11 determines the content of the failure, and then the simple automatic notification device 12 sends a failure classification signal (contact signal) (in the case of the fourth embodiment, the elevator The state is judged and the elevator state signal is also sent out).

  On the simple automatic notification device 12 side, the failure classification signal and the elevator state signal are received in step S2, and the signal contents (failure classification, elevator state) are determined in step S3.

  Next, in step S4, dialing is made to a dialing destination (telephones 14a, 14b, 14c,... In FIG. 2) corresponding to the determined signal content (failure classification) (in the case of the second embodiment, only the figure is shown). 3).

  Next, in step S5, the reception is confirmed, and if it can be confirmed, a tone signal corresponding to the signal content is transmitted in step S6 (that is, according to the failure classification in the second and third embodiments). The tone signal is transmitted, and in the case of the fourth embodiment, a tone signal corresponding to the state of the elevator is transmitted), and the process is terminated.

  If the incoming call cannot be confirmed in step S5, after waiting for a predetermined time (step S7), step S4 is executed again (dial).

  In the fifth embodiment, when the failure signal (contact signal) from the elevator controller 11 intermittently enters the simple automatic notification device 12, the telephone is called many times to the monitoring center 14. In order to prevent this, the alerting operation is not performed for a certain time after dialing to the monitoring center 14.

  In addition, when priority is given to a failure signal (contact signal) from the elevator controller 11 and a failure signal with a higher priority is input even when entering a mode in which the alarm operation is not performed for a certain period of time, In this case, a notification operation is performed.

  When the monitoring center 14 receives a failure report, when the maintenance staff is sent to the site, the failure report is repeatedly raised from the site where the failure is known to occur. In addition to wasting money, there are problems such as occupying the customer's telephone line.

  Once a notification is issued, it is more effective in terms of operation if the notification is not given for a certain period of time (assuming the time until maintenance personnel go to the site, work, and recover from a failure state).

  However, if the failure content is “passenger confinement failure”, “functional failure”, etc., and the response at the monitoring center is changed depending on the failure content (in the case of a passenger confinement failure, it will be handled immediately, but in the case of a functional failure, it will be night ) Is not responded, and responds to the next morning, etc.) After a malfunction has occurred and a notification is issued, priority is given to the signal corresponding to the content of the failure, and a mode is set in which the alarm is not activated for a certain period of time. Even in such a case, when a signal corresponding to a failure content with a higher priority is input, it is practically more practical to perform a notification operation.

  Specifically, once a notification operation is performed, a timer is activated so that a notification operation is not performed for a certain period of time even if a failure signal with the same content or a failure signal with a lower priority setting is input. Let The notification operation is not performed unless the set time elapses, a failure signal having a higher priority is input, or the timer reset is intentionally performed.

  However, since a notification operation is performed when a failure signal having a higher priority is input, a necessary notification is notified to the monitoring center 14. In addition, when a maintenance staff performs a failure response at a site where a failure report has been issued, a timer reset is performed so that even if a failure occurs again immediately after the maintenance staff leaves the site, the monitoring center 14 is notified. Reporting operation.

  In the fifth embodiment, the second to fourth embodiments in which the tone signal is transmitted to the monitoring center 14 side as well as the first embodiment in which dialing is performed to the monitoring center 14 side (no tone signal is transmitted). All examples are applicable.

  FIG. 6 shows an example of the processing flow of the simple automatic notification device 12 in the fifth embodiment. In FIG. 6, when the alarming operation, that is, the operation of dialing the monitoring center 14 and transmitting the tone signal is completed, the timer starts counting in step S11 and waits in the alarming prohibition state ( Step S12).

  Next, in step S13, it is determined whether or not there has been a failure input (input of a contact signal whose priority is determined in advance) from the elevator controller 11. If there is an input, in step S14 it has already been issued (previous). It is determined whether the reported failure signal has a high priority. If the priority order of the failure signal input this time is higher than that of the previous one, a failure signal notification operation with a higher priority is performed in step S15, and when the notification ends (step S16), step S11 is performed. Proceed to

  In step S14, if the priority order of the failure signal input this time is not higher than the above, the notification operation is not performed, and the process waits in the notification disabled state in step S12.

  If there is no failure input in step S13, it is determined in step S17 whether the notification prohibition time has expired (timer set time has expired). If the notification prohibition time has ended, this process is terminated. If the notification prohibition time has not ended, the process proceeds to step S12.
