Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote display device for displaying various types of information from a remote location at appropriate places in a number of buildings.

[Conventional technology]

In recent years, the population has become concentrated in or around urban areas, and as a result, many multi-story buildings have been built in those areas, and many people have been engaged in private or public activities in those buildings. I started to work.

Each of the buildings has a display for giving necessary notices to those who are engaged in living activities there and those who enter and exit there. Most of these indications are related to the condition inside the building or the building,
Thus, people can obtain necessary information in the building. A typical example of this is a display of a department store, in which information on sales floors on each floor and entertainments in the hall are displayed.
Further, as another example, for example, even in a high-rise residential building completely different from the department store, garbage collection, water cutoff notice, elevator operation status, and the like are displayed. As in these examples, various displays necessary for the various structures are made on various structures. These indications are usually performed by a person who is active in the building during the main job of the person.

[Problems to be solved by the invention]

By the way, in recent years, people have a potential to always want to know information related to themselves or information of interest accurately and quickly. Some of the possible sources of this information are listed below.

1. Public information Disaster occurrence situation, serious news, sports news, exchange rate, etc.

2. Regional information Road information, event information, tourist information, snow information, weather forecast, etc.

3. Information inside the building Schedule of events, information between head office and branch offices, parking lot information, elevator operation information (inspection date notice, etc.), reservation guide, welcome and receive message, emergency call, message, garbage collection, water cutoff notice, management union information, And so on.

However, of these information, those who are active in the building or who enter and leave the building can know only the information displayed in the building, and rarely contact other information. Thus, the above potential needs cannot be satisfied.

As one means for solving such a problem, the type of information to be displayed is enlarged with respect to the display in the above-described building, and appropriate information is selected from the information listed in the above 1 to 3 and displayed. Means can be considered, but to do this, a specialist technician who collects the above information, selects an appropriate one, and processes it to meet the display requirements of the display (number of displayable words, etc.) is required. Such exclusive use of a dedicated engineer is difficult to implement because the cost is too large for simply satisfying extraneous demands.

Next, first, a general operation (excluding an operation of displaying maintenance information of an elevator) of the present embodiment will be described, and then, a processing operation of the information will be described with a specific example of information. Various kinds of information are automatically and sequentially input from the information provider 1 via the communication interface 2a ₁ to the information relay 2a, or the communication interface 2a ₁ is requested by the center control device 2c.
The required information is input via. These information repeaters 2a
Since the data form (computer language, etc.) of various information input to the user differs depending on the information provider, the information relay 2a converts the input information into the data form determined by the remote display device of this embodiment. . Therefore, the memory 2a ₂ are stored data conversion the format. The conversion the format accordance connexion converted information to is stored in a predetermined area of the memory 2a ₃ (e.g. area is divided for each information provider).

The information stored in the memory 2a ₃ in this manner is transmitted to the communication interface 2 by a command from the MPU 2c ₁₃ of the center control device 2c.
The data is temporarily stored in the memory 2c ₁ via c ₄ or in the database 2 b via the storage device interface 2 c ₅ . Note that the memory 2c ₂ (an image displayed or audio output in the final various buildings, audio information) said information is information other than stored. The memory 2c ₁ and the beta base 2b have an area corresponding to the content of the information, that is, an area for wide area information, regional information, information unique to the building, etc.
Each piece of information from 2a will be stored again in the corresponding area. In order to re-store each area as described above, the information once input is transmitted to the MPU 2c ₁₃ via the keyboard interface 2c ₃ by the operator of the control device center 2, and is transmitted to the printer interface 2c ₉ via the printer interface 2c _9. printer 2d, or the display device 2e through the display in tough Ace 2c _10, or voice conversion unit 2c _11, the speaker 2f via the amplifier 2c _12, printing image, represented by voice. The operator grasps the information content represented in this way, attaches a specific code to the information content to each of the information, and according to the information content, the code of the building to which the information is to be transmitted ( Customer code) and the code of the district where the building exists (district code) are added and stored in the corresponding area. As the customer code, for example, if the information provider 1 is the head office of a company having a branch network, and the information content is unique to the company, the code of the building of each branch becomes the customer code. Also, as a district code, a prefecture code or a municipal code corresponds to this, for example,
The district code is used to indicate the area where the earthquake occurred. In this case, the information content is, of course, the content of the earthquake.

The information stored in the memories 2c ₁ and 2c ₂ and the database 2b is sent to a predetermined building. Before this transmission, the display control center 2 performs the following processing. That is, the operator of the display control center 2 sets the information to be transmitted to the specification of the information output device for displaying the information (for example, the number of characters that can be displayed, the number of screens, etc.) at the time of transmitting the information or at an appropriate time before that. While processing to match
The display time, the number of times of display, voice interlocking, color designation, and the like are performed, and the contents of the command are added to the information as a display designation code. The information processed in this way and added with the display command code is
The control code of the MPU 2c ₁₃ is matched with the transmission code system of the communication line 5 via the protocol converter 2c ₆ , the modem 2c ₇ , and the NCU 2c ₈ , and then sent to the terminal device of the target building. In the case of transmitting this information, image information, character information, and voice information are coded and transmitted as digital information in order to increase transmission efficiency, but for image information with a large amount of data, use of a dedicated line is selected, such as using a dedicated line. In addition, even when a general public line is used, consideration is given to using information other than emergency information in a time zone in which nighttime communication charges are inexpensive. In order to perform this automatically, a transmission line code for specifying the type of the communication line 5 and a transmission time code for specifying the transmission time should be added to the information in advance together with the customer code and the district code. It becomes possible.

The information processed as described above is transmitted to the terminal device of each target structure at a predetermined time via a predetermined communication line 5 together with the display designation code. Since then,
The operation of each device 3A ₁ will be described. The terminal device 3A ₁₁ transmits the information sent from the display control center 2 to the NCU 3a ₁₁₁ and the modem 3a.
₁₁₂ , input by the protocol converter 3a ₁₁₃ , and under the control of the MPU 3a ₁₁₈ , image and audio information are stored in the memory 3a ₁₁₄ , and other information such as a display designation code is stored in the memory 3a ₁₁₅ . On the other hand, CPG3a ₁₁₆ always outputs a clock pulse,
The time is being measured.

The MPU 3a ₁₁₈ always compares the display time of the display designation code stored in the memory 3a ₁₁₅ with the time measured by the CPU 3a _116, and when they match, the memory 3a
_The information stored in ₁₁₄ is taken out, and it is displayed on the building 3 by the communication interface 3a ₁₁₇ together with the display designation code.
Through the interior wiring of A ₁ and outputs to the information output apparatus 3A _12. The output information and display designation code are stored in the information output device 3A ₁₂

Here, building 3A ₁ is in the X region, recompense displayed on the display unit 3A ₁₂₃ of the information output apparatus 3A ₁₂ is an outline of the operation when a weather forecast. Now, when the information provider that provides the weather forecast provides the "tomorrow's weather forecast" for each region, this is input to the information repeater 2a,
It is converted into the data form that matches the data format of a remote display device of the present embodiment temporarily stored in the memory 2c ₁ of the center controller 2c to. Next, the operator of the display control center 2 stores the stored "tomorrow's weather forecast" of each region in the memory 2c.
_It takes out from ₁ and displays it on the display device 2c, attaches an information content code corresponding to "weather forecast" to all of them, attaches a district code for each local forecast, and reads "weather forecast" in the database 2b. Is stored in the area corresponding to.

Assuming that it is predetermined that the above-mentioned information “tomorrow's weather forecast” be sent out to each building at night using a telephone line, the operator of the display control center 2 will call the local `` Tomorrow's weather forecast '' is retrieved from the database 2b and displayed on the display device 2c, taking into account the display capacity of the display unit in each building, processing the contents of `` tomorrow's weather forecast '', and displaying the time, Display time, impressions,
The display time interval and display mode (continuous display, blinking display, etc.) are determined, and a transmission command is issued with a code attached to each item. In response to this transmission command, the MPC 2c ₁₃ refers to the district code and transmits the "tomorrow's weather forecast" of each region to each of the other buildings for each region. It was but go-between, the building 3A ₁ in the X region, at night, (in the case transmitted is the night of midnight after the day) the next day so that the X local weather forecast for is sent.

Terminal apparatus 3A ₁₁ buildings 3A ₁ is the X local weather forecast stores in the memory 3a ₁₁₄ of accessory encoding memory (display time, display time, display the number, code time interval, and display form) Store in 3a ₁₁₅ . Thereafter, the MPU 3a ₁₁₈ of the terminal device 3A ₁₁ constantly compares the clock time of the CPG 3a _{116 with} the display time. Thus, at a commanded display time (e.g., at 7) MPU 3a ₁₁₈ outputs a display mode code stored in the weather forecast and the memory 3a ₁₁₅ stored in the memory 3a ₁₁₄ to the information output apparatus 3A _12.

The MPU 3a ₁₂₅ of the information output device 3A ₁₂ temporarily stores the information in the memory 3a ₁₂₂ and then inputs the information to the display control device 3a ₁₂₄ .
Although the display control unit 3a ₁₂₄ was to display the feature codes (e.g., continuous display) displayed on the display unit 3a ₁₂₃ the connexion weather forecast.
On the other hand, the MPU 3a ₁₁₈ of the terminal device 3A ₁₁ has a predetermined display time (for example, 1) according to the code stored in the memory 3a _115.
Min) and outputs a signal for stopping the display of weather forecast has passed information output apparatus 3A _12, MPU3a ₁₂₅ of the information output apparatus 3A ₁₂
Outputs an erasure command to the display control device 3a ₁₂₄ to erase the display of the weather forecast on the display unit 3a ₁₂₃ . Thereafter, the MP of the terminal device 3A ₁₁
U3a ₁₁₈ is stored in the memory 3a ₁₁₅ the display time (1 minute in the above example), impressions (e.g. 10 times), the time interval (e.g.
It was prepared in each code of 15 minutes) to the display command signal to the connexion information output apparatus 3A _12. By such an operation, the display unit 3a
_{At 123} , the weather forecast of the day in the X region is automatically displayed for one minute at intervals of 15 minutes from 7:00 to 9:15.

The specific operation example when the operation and the information in the present embodiment is the weather forecast has been described above. By the way, the communication line 5 connecting the display control sensor 2 and each building has a limited capacity. Therefore, when the number of buildings controlled by the display control sensor 2 increases, the amount of use of the communication line 5 also increases, so that much time is required for transmission. In this case, another display control center 4 is installed as shown in FIG.
The display control center 2 share via the communication line 5 for ₁ to 3 A _n, another display control center 4 takes charge via the communication line 6 for building 3B ₁ ~3B _m. This solves the problem of the line capacity.

Since the information organized by the display control center 2 is sent to the other display control center 4, an information repeater is unnecessary, and the workload of the operator is reduced. If the information processed by the display control center 2 and the code attached to this information are sent to the other display control center 4, the other display control center 4 can automatically perform the subsequent operations. This can eliminate the need for an operator.

Next, the information input device shown in FIGS. 2 and 3 (b)
3A ₁₃ will be described. Among various information, there is a building
From 3A ₁ to another building, or even considered the information to be displayed on the building 3A ₁ itself from building 3A _1. The information input apparatus 3A ₁₃ is used in such a case. That is, when sending information from building 3A _1, by operating an appropriate person, for example, janitor of the building 3A ₁ is a personal-computer 3A ₁₃₁ or enhanced phone 3A ₁₃₂ or tablet 3A ₁₃₃ shown in FIG. 2 Information Is input to the terminal device 3A ₁₁ via the communication interface 3a _117, and is stored in one of the memories 3a ₁₁₄ and 3a ₁₁₅ of the MPU 3a ₁₁₈ . Here, if the information is information to be displayed on all of the buildings including the building 3A ₁ or on the selected building, the stored information is controlled by the terminal device 3A ₁₁ via the communication line 5 for display control. It is input to the center control device 2c of the center 2. Subsequent operations are the same as those described above. Further, information is information specific to a building 3A _1, for example if the notification such inspection date and time of the building 3A ₁ elevator, this information without being sent to the display control center 2, the information output apparatus from the terminal apparatus
Is sent to 3A _12, the display is made on the display unit 3a _123.
Even in this case, the information is temporarily stored in the display control center 2.
To the display unit 3a ₁₂₃ by the above operation.
May be displayed.

Here, an operation in the case where elevator maintenance information is displayed will be described. Elevator maintenance includes elevator inspection, elevator repair, etc. The indications for this include "elevator under inspection",
"Elevator is currently out of order", "Elevator is under repair",
There is an indication such as "Elevator is not used right now". These displays are stored in advance in the memory 2c ₂ of the center control device 2c or in the memory of each terminal device (the memory 3a _{115 in} the case of the terminal device 3A ₁₁ ). Hereinafter, the display is stored in a memory of the terminal device, and will be described when performing the inspection of the elevator building 3A _1.
