Description:
This application is a continuation of application Ser. No. 483,488 filed Feb. 22, 1990, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     The present invention relates to an embedded type intelligent switch system to be mounted on the wall surface near the entrance of an intelligent building or the like and to be used for providing information and for controlling operation of the building facilities. 
     In intelligent buildings as constructed in recent years, various facilities are furnished such as lighting control, air-conditioning control, entry and exit control, fire detection system, information communication system, etc. and the on-off operation and the control operation for these facilities are performed in each office. For this purpose, various types of switches are installed in the offices such as the switch to turn on or off the lighting equipment, or the air-conditioning systems or the switches to control and adjust the illuminance or the temperature in the rooms. These switches are furnished in separate groups for each partition of the offices and are usually mounted on the wall surfaces near the entrance or at other suitable positions. Therefore, when the offices are partitioned, the positions of the switches are determined according to the partitions. 
     In the above switch operating system as conventionally adopted, the switches for lighting equipment and the switches for air-conditioning system are separately furnished, and each group of switches and the facilities under control of such switches are limited and fixed in the extent of one-to-one. Namely, the facilities and the extent of the control are limited for each switch, and only one function is provided for such switch. 
     In the office building, the room partitions and the room layout are frequently changed. When such a change occurs for the conventional switch operating system, the switch group to control the facilities in the same room has to belong partially to the other room after the change. In this case, it is necessary to move a part of the switches to the switch panel of the other rooms. For this reason, the wiring, the switch installation and the rearrangement of the room have to be done each time the room layout is changed. 
     One of the methods to cope with such a change in a flexible manner is to minimize the re-arrangement by adopting a wireless remote control system. However, the wireless remote control system requires a transmitter and a receiver, and it is also often necessary to divide the transmitter in order to match the room layout. With the increase of the facilities to be controlled, more transmitters or complicated transmitters are needed. This results in the increase of the installation cost of the system and the more troublesome arrangement of the transmitters. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention, to, provide the intelligent switch capable adjusting and controlling the lighting and air-conditioning near the entrance door of an office building so that the facilities and the extent of the area under control can be freely changed. Another object of this invention is to furnish the means to flexibly cope with the change of the office layout. Still another object of the invention is to make up a system where the control command can be input and the information can be output by intelligent switches. 
     To attain these objects, the intelligent switch system according to the present invention comprises intelligent switches, which are embedded in a wall surface near the entrance on each floor of the building, are capable to output and display the selection menu or the information from the screen of the display unit with a touch panel on the front side thereof and are capable to input the selected instructions. An information processing unit is connected with each of the intelligent switches to give, receive and process the information. A regulatory system is located within the building. The regulatory system in the building is controlled by the intelligent switches and the information is output from the information processing unit. The intelligent switch is provided with a display unit with a touch panel and a data processing device, which displays the menu screen on the display unit with the touch panel and sends the touch input information after recognizing and processing the touch input on the screen. The intelligent switch possesses a top menu consisting of the information offer items and the, intra-building control items, and when an item of the top menu is selected by touch input, the screen is turned to the development screen of the item in order to offer the service for such an item. 
     With the arrangement as described above, the intelligent switch system of this invention can offer the necessary information by touch input on the intelligent switches, which are embedded in the wall surface near the entrance on each floor and freely control the regulatory systems in the building. Each switch also possesses a top menu consisting of the information offer items and the intra-building control items. When an item of the top menu is selected by touch input, the screen is changed to the development screen of the item and offers the service for such an item. Thus, messages, news and information can be freely offered, and air-conditioning and lighting can be easily controlled by touching the screen. 
     Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     In the following, the embodiments of the invention will be described in connection with the drawings. 
     In FIGS. 1, 2 and 3, 1 refers to a CPU, 2 a Kanji ROM, 3 a VRAM, 4 a display controller, 5 a touch input interface, 6 a liquid crystal display plate with a touch panel, 7 a ROM, 8 a RAM, 9 an external communication interface, 10 a computer, 11 an intelligent switch, 12 a front panel, 13 an external frame, 14 an accommodating housing, 15 a mounting wall, and 16 an entrance. The display controller 4 generates Kanji characters and alphanumerics such as JIS No. 1 Standard Kanji, JIS No. 2 Standard Kanji and non-Kanji characters, and develops these characters and patterns on the display screen. The liquid crystal display plate with the touch panel 6 is a liquid crystal display plate furnished with a touch panel on the front thereof. For example, when a liquid crystal display plate commercially available consisting of a screen of 640×400 dots is used, the screen is approximately of B5 size. When this liquid crystal display plate is used to develop and display Kanji characters in 24×24 dots, it is possible to display the information consisting about 16 lines having 26 characters in each line. The touch input interface 5 is to input and process the touch signals from this liquid crystal display plate with the touch panel 6. In ROM 7, the programs such as monitor, communication control, input control of touch panel, display output control, download manager, etc. are stored. RAM 8 is used to store the screen data to be displayed on the liquid crystal display plate with the touch panel 6 and to store the individual program suitable for each application as work area. The screen data and the programs are loaded by the download manager when they are prepared by the other computers. CPU 1 is to process the input/output information on the liquid crystal display plate with the touch panel 6 and to communicate with an external host computer or with the computer 10 such as the building control system through the external communication interface 9 when necessary. 
     FIG. 2 is an external view of an intelligent switch, in which a circuit of FIG. 1 is accommodated and the liquid crystal display plate with the touch panel 6 is arranged on the front. This intelligent switch 11 is provided with a liquid crystal display plate 6 with the touch panel at the center of the front panel 12, and it is embedded, for example, with the surface of the front panel 12 on the same level as the wall surface, and the external frame 13 is protruded from the wall surface. Because the liquid crystal display plate is of a commercially available thin type, the intelligent switch 12 has the thickness of about 7 cm even when an accommodation housing 14 is furnished on its rear side, accommodating all of CPU 1, Kanji ROM 2, VRAM 3, display controller 4, etc. Accordingly, it is possible to fabricate the intelligent switch 12 in A4 size and to embed it in the wall 15 near the entrance 16. 
     Next, a description will be given on the building control system, in which the intelligent switch according this invention is used. 
     On the liquid crystal display plate of the intelligent switch according to this invention, a top menu as shown in FIG. 4 is usually displayed. Icon 21 displays when it is raining, and icon 22 displays the image corresponding to each of the choices 23. By touching the icon 22 or the display area of the choice 23 on this display screen, the touched item is selected, and detailed information is developed and displayed. In this top menu, the information is offered by &#34;Today&#39;s information&#34; and &#34;News flash&#34;, and the lighting and air-conditioning are controlled and adjusted by &#34;Lighting control&#34;, &#34;Air-conditioning and temperature control&#34;, and &#34;Overtime air-conditioning ON/OFF&#34;. 
     FIG. 5 is an example of the configuration of the building control system, in which the above intelligent switch is mounted on a wall surface near the entrance of a corridor, for example. In this example, the information processing unit consisting of a floor station 33, a host computer 41, a building control system 42, etc. are connected with the intelligent switch 34 through a communication line, and the information is given, taken and processed between these devices and the intelligent switch 34. Further, the intra-building regulator units such as lighting equipment 36, air-conditioner 37, etc. are connected with these devices which provide intra-building regulation control information. The telephone set with data communication function 31 on each floor and the computer terminal for tenant manager 32 are connected with the host computer 41 through DPBX (digital electronic exchange) 40, and the external news distribution line is connected. Also, building control system 42, computer terminals for building managers 43 and 39, floor station 33, and rain sensor 38 are connected. The intelligent switch 34 and the lighting controller 35 are connected with the floor station 33. The lighting equipment 36 is connected with this lighting controller 35, and the air-conditioning system 37 is connected with the building control unit 42. The floor station 33 performs the centralized control of several intelligent switches 34 by multi-task processing, and the intelligent switches 34 are connected by a multi-drop system. 
     In the lighting control, when ON/OFF status of the lighting is displayed on the liquid crystal display plate of the intelligent switch 34 and the user performs ON/OFF operation of the lighting while watching the screen with the layout display, ON/OFF signals by such an operation are sent from the intelligent switch 34 to the lighting controller 35, and the lighting equipment is controlled. The setting and the change of the lighting control area are achieved by each computer terminal (32, 39, 43) through the floor station 33. In the air-conditioning control, ON/OFF operation of the air-conditioner and fine adjustment of the preset temperature are performed through the display of ON/OFF status and the running status such as the preset temperature. ON/OFF operation, temperature control, area setting and change are achieved from the computer terminal through the building control system 42. In the news flash, the external news distribution line is connected through DPBX, and the most up-to-date news information is taken into the host computer 41. Thus, the latest information can be displayed on the intelligent switch 34. For the rain information, rain sensors 38 are installed on building roof and on the ground, and the umbrella-shaped icon 21 is displayed on each screen of the intelligent switch 34 when it is raining. In buildings, particularly, in large buildings, people inside cannot find out immediately whether it is raining or not outside the building. In such a case, they first become aware of the rain only when they come to the exit of the building, and they-have to go back to take rain gear. This means wasting several minutes or more for a large building. The umbrella mark by the icon 21 on the intelligent switch 34 provides convenience in such a case and is very effective to eliminate wasting time when the office workers are going home or going out. 
     Although not shown in the drawing, a key box for each room may be installed at a specific place in order to check that all keys are returned to key box from each tenant on the floor. Based on the presence or absence of the keys, the lighting and the air-conditioning on each floor may be checked and controlled, and those operating can be stopped when all keys are already there. There are key boxes already known, for each of which a card reader is provided. With the user ID numbers stored in the card reader, the keys with the registered user ID numbers can be freely taken away or given back, and this facilitates the key control. 
     Next, a description will be given on the screen configuration of the intelligent switch as well as the selection and the changeover of the switch. Normally, the top menu screen 51 is displayed, but when any of the choices &#34;Today&#39;s information&#34;, &#34;News flash&#34;, &#34;Lighting control&#34;, &#34;Air-conditioning and temperature control&#34;, &#34;Air-conditioning ON/OFF&#34;, etc. is selected by touch input, the screen is turned to the menu screens 52-56 as shown in FIG. 6. 
     For example, in the menu screen 52 of &#34;Today&#39;s information&#34;, the menu such as &#34;Regular inspection of elevator&#34;, &#34;New installation of coffee vending machine&#34;, &#34;Information about New Year&#39;s party&#34;, etc. including the message from the building manager or the tenant manager are displayed as given in FIG. 7 (a). If any of these items is selected, the screen 52&#39; for the detailed information corresponding to each selection item is displayed as shown in FIGS. 7 (b)-(d). The information is input from the computer terminal of the building manager 39 or 43 and the computer terminal of the tenant manager 32. 
     As described above, each of the menus for item selection is displayed on the menu screens 52-56. When there are two or more pages of screens, the next page key and the preceding page key 61 to select these screens or the menu screen selection key 62 to select the other menu screen are displayed at the end of the screen. 
     On the menu screen 53 of &#34;News flash&#34;, the category (genre) selection menu such as &#34;General news&#34;, &#34;Political and economic news&#34;, &#34;Industry and enterprise news&#34;, &#34;Overseas news&#34;, etc. is displayed as shown in FIG. 8 (a). When the category is selected, the menu for the selection items is displayed as given in FIGS. 8 (c) and (d). Such &#34;news flash&#34; is usually wanted at lunch time for a normal office building (i.e., the most frequently used display). Accordingly, if the schedule is controlled (i.e., by a schedule control function) in such a manner that the menu screen 53 of &#34;News flash&#34; is displayed instead of the top menu during lunch time, the desired information becomes available through the least number of selection steps. 
     On the menu screen 54 of &#34;Lighting control&#34;, various selection keys 66 are displayed together with the floor layout 63 or the controlled area layout 64 as given in FIG. 9. In the floor layout 63, the position of the layout for the controlled area is emphatically displayed. In the layout for the controlled area 64, ON/OFF status display of each block area and the installed position display 65 of the intelligent switch are displayed. The menu screen selection key and the shift key, ON/OFF operation key, etc. are included in these selection keys 66. The controlled area is shifted by each block, and the scope of shift is limited for each tenant. ON/OFF operation may be performed in such a manner that it is turned OFF when it is in an ON status and it is turned ON when it is in an OFF status by touching each block area instead of ON/OFF operation key. By this touch input, the signals for the lighting control are issued. The layout for the controlled area can be changed by minimum operation of ON/OFF control. 
     In the menu screen 55 of the &#34;Air-conditioning temperature control&#34;, the temperature control keys for each room of the entire building are displayed on screen together with the layout as shown in FIG. 10. When the key on the screen is touched, the information of that key, i.e. the control signal, is issued. In the figure, the standard temperature as set at the center can be adjusted by ±1° C., and the regulation for all tenants is achievable by the whole building regulation key. Individual regulation is performed by each key for each room. 
     In the menu screen of the &#34;Air-conditioning ON/OFF&#34;, the user ID input screen by ten-key is displayed as given in FIG. 11 (a). When the user ID number is input, the user ID number is collated, and the layout screen 56&#39; where the overtime ON/OFF operation can be input is displayed. 
     As described above, the present invention offers an intelligent switch, which comprises a display unit with touch panel on the front thereof and a data processing unit, and in which the top menu consisting of the information offer items such as &#34;Today&#39;s information&#34; or &#34;News flash&#34; and the intra-building control items such as &#34;Lighting control&#34;, &#34;Air-conditioning temperature control&#34;, &#34;Overtime air-conditioning ON/OFF&#34;, etc. is displayed, and these items are developed according to each selection. Because the screen is changed over and the input information is processed by the menu display and the touch on the displayed area, the registration and the change of the screen and the change of the touch area can be accomplished freely from computer terminals, and a compact and flexible system can be provide. For example, the information can be input or the lighting block or the air-conditioning block can be set from the computer terminal of each manager, and when the contents are registered in the host computer, these are transferred to each intelligent switch and building control system through the floor station and are processed at the intelligent switches and the building control system according to each content. 
     It is naturally obvious that the present invention is not limited to the above embodiment, and various modifications and changes are conceivable. For example, liquid crystal display plate is used in the above embodiment, but the other types of display may be employed. Also, 5 items are displayed in the top menu, whereas statistical data, message or other information may be displayed, and the items may be increased such as electric key control or other facility control. Further, if there is no touch input on the liquid crystal display plate with the touch panel within the predetermined time, the backlight automatic light-out function by time-out or automatic light-on function by screen touch is executed. The schedule control function may be furnished to display the most desired screen for each time zone, e.g., instead of top menu screen, the menu for &#34;Lighting control&#34; may be displayed in the morning, and the menu for &#34;News flash&#34; at lunch time so that the most desired screen may be displayed. 
     As it is evident from the above explanation, the menus are hierarchically displayed on the display unit with touch panel according to this invention, and the information is offered or building facilities are controlled by touch input. This makes it possible to use the system as multi-function terminals and to provide a wide variety of information. Moreover, external information or internal liaison information can be quickly and abundantly offered near the entrance of each room. Also, because input is performed from the screen, the switching system can be easily changed by altering the screen without rearranging the wiring system. This means more flexible action when office layout is changed. The operation is simple, maloperation rarely occurs, and, even when it occurs, it can be easily identified. Further, because display is made hierarchically, dividing into two or more screens, a number of functions can be provided with the system in compact size.
