Next, first, a general operation of the present embodiment will be described, and then, a processing operation of the information will be described with a specific information example. Various types of information are automatically and sequentially input from the information provider 1 via the communication interface 2a ₁ to the information relay 2a, or required information is transmitted via the communication interface 2a _{1 according} to a request from the center control device 2c. Information is entered. Since the data form (computer language, etc.) of the various information input to the information relay 2a differs depending on each information provider, the information relay 2a transmits the input information to the data determined by the display device of the present embodiment. Convert to form. 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 information other than the information is stored.
The memory 2c ₁ and the database 2b have an area corresponding to the content of the information, that is, an area such as wide area information, regional information, information unique to the building, etc., and each information from the information relay 2a corresponds. Will be re-stored in the designated area. In order to re-store the information for each area in this manner, the information once input is transmitted to the MPU 2c ₁₃ via the keyboard interface 2c ₃ by the operator of the display control center 2 and then transmitted to the printer interface 2c ₉ via the printer interface 2c _9. Printer 2d

Or in the sound conversion unit 2c _11,, the speaker 2f via the amplifier 2c _12, printing image, represented by voice. The operator grasps the information content expressed in this way, attaches a specific code to the information content to each of the information, processes the information into a form suitable for displaying and broadcasting, and according to the information content. A code (customer code) of a building to which the information is to be transmitted, a code of a district where the building is located (a district code), and the like are assigned and stored in a corresponding area. As the customer code, for example, when 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 at each branch is the customer code. A district code corresponds to a prefecture code or a municipal code. For example, a district code is used to display an occurrence district when an earthquake occurs. 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 that displays 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. At the same time as re-processing so as to match, display time, display count, voice interlocking, color designation, etc. are performed, and the designated contents are added to the information as a display designation code. The information processed in this way and the display designation code is added, under the control of the MPU 2c ₁₃ , the protocol conversion unit 2c ₆ ,
After being matched with the transmission code system of the communication line 5 via the modem 2c ₇ and the NCU 2c ₈ , the data is transmitted 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. Do,
In addition, even when using a general public line, consideration is given to using information other than emergency information in a time zone during 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 building 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 CPG 3a _116, and when both 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
To the MPU 3a via the communication interface 3a _121.
After temporarily stored in the memory 3a ₁₂₂ by _125, it is input to the display control device 3a ₁₂₄ . The display control device 3a ₁₂₄ converts the input information into the display unit 3a in the mode specified by the display specifying code.
Display at ₁₂₃ . FIG. 2 shows an example of the installation location of the information output device 3A ₁₂ and therefore the display unit 3a ₁₂₃ . The information output apparatus 3A ₁₂ is is to display information in image, it may require means for notifying the information by voice. (Often the same location as the information output apparatus 3A ₁₂ for display) appropriate locations speaker 3a _'123 is in a building provided thereto is placed. When audio information is output at a specified time with audio indication code from the terminal device 3A _11, information output apparatus 3A ₁₂ is incorporation this through communication in tough Ace 3a _121, and stores the MPU 3a ₁₂₅ in the memory 3a _122. Next, the MPU 3a ₁₂₅ fetches the voice information and the voice designation code from the memory 3a _122, and converts the voice information into a mode (for example, the number of utterances) specified by the voice designation code.
Enter _a'124 . _'124 the voice information input speaker 3a' speech conversion system 3a into a speech signal that drives _123. The audio signal 'is amplified by _125, a speaker 3a' amplifiers 3a to notify by voice information by driving a _123. Here, building 3A ₁ is in the X region, the information 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,
Is converted to the matched data form the data mode of the display device of the present embodiment temporarily stored in the memory 2c ₁ of the center controller 2c to. Then, the operator of the display control center 2, information content stored in the "tomorrow's weather forecast" of each region is displayed on the display device 2c is taken out from the memory 2c _1, corresponding to "weather forecast" to all of these With the code,
A district code is assigned to each local forecast, and stored in an area corresponding to “weather forecast” in the database 2b. 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 MPU 2c ₁₃ transmits the "tomorrow forecast" of each region to each building in each region with reference to the region code. 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 specified 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. As above, the specific operation example when the general operation and the information in the present embodiment is the weather forecast has been described. by the way,
The communication line 5 connecting the display control center 2 and each building has a limited capacity. Therefore, when the number of buildings controlled by the display control center 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 building 3A 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 recording apparatus shown in FIGS. 2 and 3 (b)
The 3A ₁₃ and the information selection device 3A ₁₄ will be described. In the description so far, the information has been about a system in which information is unilaterally sent from the display control centers 2, 5 to each building. However, on the building side, only the necessary information or the most desired information is displayed at an appropriate time in consideration of the specificity of the building and other circumstances, or only the building or only the building or the building and There are times when it is desired to make a display unique to a specific building only. The information recording apparatus 3A ₁₃ and information selection device 3A ₁₄ is a device provided for this. First, the building 3A _1, for example, in order to be displayed this when the want for a weather forecast, a weather forecast is summer as not sent from the display control center 2. At a certain time, to display the weather forecast in building 3A ₁ is appropriate person building 3A _1, for example, administrator operates the keyboard 3a ₁₄₃ information selection device 3A _14, enter the code for weather forecast I do. The entered code is displayed on the display 3a ₁₄₄ for confirmation. MPU 3a ₁₄₅ transmits to the terminal apparatus 3A ₁₁ via the communication in tough Ace 3a ₁₄₁ the input code, the terminal device 3A ₁₁ This protocol conversion with building code portion 3a _113, modem 3a _112, NCU 3
and transmits to the display control center 2 via a communication line 5 through a _111. The display control center 2 constructs the building 3A in the data of the weather forecast in the database 2b based on the transmitted code.
₁ taken out of the local data, and sends the weather forecast of the data that was taken out through the communication line 5 in buildings 3A _1. Terminal apparatus 3A ₁₁ buildings 3A ₁ is NCU3a _11, modem 3a _112, via the protocol conversion unit 3a ₁₁₃ receives the data, MPU 3a
₁₁₈ is an information selection device from the communication interface 3a ₁₁₇
And it sends to the 3A _14. The information selection device 3A ₁₄ receives this via the communication in tough Ace 3a _141, is displayed on the display 3a ₁₄₄ stores in the memory 3a ₁₄₂ under the control of the MPU 3a _145. The manager knows that the weather forecast has been transmitted by _{looking at} the display on the display 3a ₁₄₄ , and operates the keyboard 3a ₁₄₃ to instruct the display of the weather forecast, display conditions, and the like. Now, if an instruction to immediately display the weather forecast is input, the weather forecast data stored in the memory 3a ₁₄₂ is transmitted to the terminal device 3A ₁₁ via the communication interface 3a ₁₄₁ , and the terminal device 3A ₁₁ and it sends the data under the control of the MPU 3a ₁₁₈ to the information output apparatus 3A _12. Thereafter, the weather forecast is displayed on the display unit 3a ₁₂₃ through the same procedure as described above. Thus, by accessing the database of the display control center 2 using the information selection device 3A _14, it is possible to display when wants information wants the building side. Next, the case where performing display only required building 3A _1. For example building 3A ₁ of the first machine failure among the plurality of elevators, when driving stopped by reason of the test such as the janitor keyboard 3a ₁₄₃ information selection device 3A _14, while watching the display 3a ₁₄₄ "1 And the MPU 3a ₁₄₅ stores this in the memory 3a ₁₄₂ . When janitor instructing display, MPU 3a ₁₄₅ is taken out of the data stored in the memory 3a _142, which was transmitted to the terminal apparatus 3A _11, the terminal apparatus 3A ₁₁ immediately information output device the transmitted data 3A ₁₂ Output to As a result, "No. 1 elevator operation stop" is displayed on the display unit 3a ₁₂₃ . Also, when you want to send the display information from the building 3A ₁ to other specific structures, together with the display information on the keyboard 3a ₁₄₃ Enter the code of the other specific buildings, these terminal devices 3A ₁₁ To send to. The terminal device 3A ₁₁ secures a communication line 5 with the building based on the input building code (if the communication line 5 is a telephone line, the telephone number of the building is automatically dialed to call the other party. (Calling), and then transmitting the display information to the terminal device of the partner building. Display of the transmitted information on the building side is performed in the same manner as described above. As described above, the display data is stored in the keyboard 3a ₁₄₃ each time it is displayed.
In an example it has been described in which the input, it is possible to reduce the burden of the input by the keyboard 3a ₁₄₃ by using the information recording apparatus 3A _13. That is, the display information includes unique words, for example, "today's garbage collection date", "elevator testing", "conference room in use", etc. If these words are stored and taken out and used when necessary It is no longer necessary to make an input using the keyboard 3a ₁₄₃ each time they are displayed.
