DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on preferred embodiments shown in the drawings. FIG. 1 is a schematic configuration diagram of an embodiment of an elevator emergency guidance system according to the present invention. In FIG. 1, a central information center 1 comprehensively monitors elevators of a plurality of buildings, and is connected to a communication base station 2 by a telephone line, for example. The communication base station 2 communicates with a GPS display mobile 3 carried by a maintenance person via a known GPS (Global Pos
itioning System: the world's leading system). The central information center 1 is configured to mutually perform wireless communication with a control device 4 provided in an elevator control device of each building. In the elevator car 8, a display device 9 is provided in addition to a well-known emergency call button not shown, and these are connected to the control device 4.
The control device 4 converts a signal form used inside the control device 4 into a communication form performed between the central information center 1 and a communication unit 5 that communicates with the central information center 1. A conversion unit 6 for performing reverse conversion and a transmission unit 7 for wireless transmission are provided. The display device 9 has, for example, a function of displaying map information around the building housed in the control device 4 and displaying the position of a maintenance person carrying the GPS display mobile 3 on a map.

The operation of this embodiment configured as described above will be described below with reference to the flowchart of FIG. The symbols S1 to S8 indicating the transmission and reception of the signals illustrated in FIG. 1 correspond to the symbols S1 to S8 indicating the processing steps in FIG.

First, when a callback is received from a passenger trapped in a car (S1), a notification is issued to the central information center 1 by the control device 4 (S2). At this time, inside the control device 4, a signal indicating the callback operation of the passenger by the communication unit 5 is transmitted to a communication protocol transmitted to the central information center 1, for example, a communication command for adding a destination header and a process of a reception response. In addition to performing editing such as loading, the conversion unit 6 performs communication mode according to the communication with the central information center 1, for example, setting of transmission speed, setting of signal transmission method, and the like. The data is converted into a signal and transmitted to the central information center 1.

Next, the central information center 1 searches through the communication base station 2 for a maintenance person who performs maintenance work, and calls the maintenance person who is closest to the maintenance person (S3). If the maintenance person at the closest position can be called, a signal for displaying the GPS information up to the site is transmitted to the maintenance person, and the information is displayed on the GPS display mobile 3 carried by the maintenance person ( S4). Conversely, G carried by maintenance personnel
The location information of the maintenance person who is closest to the communication base station 2 from the PS display mobile 3 is transmitted (S
5). This information is further transmitted from the communication base station 2 to the central information center 1, edited as GPS information to be displayed in the car, and transmitted to the control device 4 (S7).

[0015] Inside the control device 4, the reverse process to the transmission is performed.
That is, after the transmitted wireless signal is received by the transmission unit 7, the communication unit 5 and the conversion unit 6 extract a signal indicating the position of the maintenance person. Based on the extracted signal, the position of the maintenance person is displayed on the display device 9 installed inside the elevator car 8 together with a map around the building (S
8).

Thus, according to this embodiment, after the passengers are trapped in the car, it is possible to search for a maintenance person who is closest to the location of the building. The shortest course to the site on the GP
It can be notified on the S screen. In addition, the passenger can be provided with information on the display device 9 in real time, such as where the maintenance person is at present, how long the maintenance person is, and how long it takes to arrive. Therefore, the highest priority is given to rescuing passengers in the shortest time, and the current situation can be communicated.

It goes without saying that a display of a mobile phone can be used as the display device 9 in the car.

[0018]

As is apparent from the above description, according to the present invention, when an elevator failure occurs in which a passenger is trapped in a car, the movement of maintenance personnel heading for the building concerned is trapped in the car. By notifying the passenger visually, the feeling of anxiety and frustration of the passenger can be reduced.

In addition, it is possible to select and guide a maintenance person who arrives at the site where an elevator failure has occurred in the shortest time, and it is possible to obtain an effect that the rescue time for passengers can be reduced.
