Abstract

A information browsing system comprises a server terminal and a client terminal, wherein the server terminal distributes various HTML documents through communication circuit while the client terminal browses various information distributed by the communication circuit. The server terminal is provided with a display control process part so that when a client terminal makes a request to browse a prescribed HTML document, the display control process part of a Web server terminal obtain the access level from the user information file of a user of the client terminal, judges whether or not the HTML document requested by the user can be displayed and altered by the user according to the access level, and delivers the requested HTML document only when the document can be displayed or altered.

Description

Information browsing system

The present invention relates to information browsing system, particularly the internet usage browser is browsed the information browsing system of various pieces of information.

In recent years, the information browse technology that is called WWW (Word Wide Web) obtains using in computer network system that is called the Internet and the internet popularized rapidly.

WWW is that a kind of use HTTP (HTML (Hypertext Markup Language)) provides to be called the mechanism of the data that HTML (HTML (Hypertext Markup Language)) writes.

In this class network system, the Web server program is installed in computing machine, and promptly in the Web server terminal, these terminals are connected at each point with network, and viewed data file is by program management.

Each user starts the browser that is installed in the personal computers such as for example client terminal that his/her is connected with network, and imports the URL (uniform resource locator) of indicating predetermined data file position.

Respond this operation, browser is connected to the Web server terminal of appointment by the communication protocol that is called TCP/IP such as communication lines such as LAN cable or telephone wire basis, and shows the data of receiving from the Web server terminal on screen.

After receiving data, the client terminal disconnection is connected with the Web server terminal.Client terminal is once more according to receiving the Web server terminal from user's new request of data, and receives and show required data.

Figure 19 represents general information browsing system, and especially for the system of office building.

In this case, lessee A has occupied second to the 4th floor respectively to F, and is used between the building management of maintenance/operation of building service and the parking lot has occupied ground floor.Each layer all has elevator.The parking lot is managed by different management companies respectively with elevator.In other words, buildings is by the operation of a plurality of management companies.

LAN cable 10 is laid by each floor of buildings, and the client terminal of on each floor, installing 21 to 26 for the lessee, be arranged on the client terminal 27 in the ground floor parking lot, Web server terminal (server terminal) 11 that is arranged between one deck building management is connected by LAN cable 10 each other with client terminal 28.

The information stores that is notified to the buildings resident is in Web server terminal 11.For example comprise can be by the html document of the menu of reference when the keeper when each facility of buildings carries out the management of equipment/control for this information.Except the html document of indicating the notice that cleans the floor, also has menu of dining room or the like.The user uses browser can browse these pieces of information by client terminal 21 to 28.

Thereby the content that must press document is to user's some restriction in addition that can browsing document.

Usually, in this system, user that can browsing document will register in advance.Thereby carry out authentification of user by making the user carry out register, determine the permission that the document to this user shows/forbid like this.

In this traditional information browsing system, only two kinds of selections are made definitely, whether promptly given user can visit a document (information).Therefore, this system can not be used for such system, promptly wherein must have other user management of random access level about the determining of the change of the permission that shows/forbid and document, for example, wherein use the application program of WWW structure operation system and the situation of buildings supervisory system with respect to each.

For example, in a buildings application program, when when using browser in the client terminal to show to be used to import the window of personal information, have only limited user, for example the member of personnel department can visit the html document of this window.

May need to design this system and make it only permission shows personal information from input to other employee.

In this case, traditional information browsing system adopts the method for carrying out register by the login name that uses the login name that allows information browse simply and permission information to change selectively like this.According to this method, specific user must have two login names.This system that just makes is difficult to use.

In the buildings supervisory system, when the browser display equipment state in using client terminal and the window of instruction manipulation, must carry out Access Management Access by this way, i.e. list of devices in the A department in lessee A office and the user who belongs to A department is allowed with the demonstration of these device-dependent beginning/end/settings/change operation, and to only allowing to show B department list of devices with some users, and the user who belongs to lessee B office is forbidden showing list of devices in the office of lessee C.

Use the method for user name can not be suitable for the control of this complexity in traditional information browsing system selectively.

The present invention makes in order to address this problem, and its objective is can be to the information browsing system of the accurate management of each user to the visit of all kinds document in order to provide.

In order to reach the above object, in a kind of information browsing system of the present invention, server terminal comprises and shows control and treatment equipment, this equipment is used for the request that basis is browsed from the html document to predetermined of client terminal transmission, acquisition is from the access level in the user profile file that is provided with corresponding to the client terminal user, determine the demonstration of the html document asked based on this access level and change for this user, and only when the demonstration of document or change are allowed to, could send the html document of being asked to the user whether for allowing/forbid.

Thereby have only when the access level that obtains from the user profile file allows the html document of this request to show or changes, the html document of being asked just is sent to the user.

The present invention will be described hereinafter with reference to accompanying drawing.

Fig. 1 is the information browsing system of expression according to one embodiment of the invention.Identical parts (referring to Figure 19) in identical in the following description labelled notation and the previous description.

Consider that information browsing system is used for the situation of buildings supervisory system, the equipment that wherein constitutes building service is monitored/controls by Web server terminal 11 from any one client terminal 21.Notice that the setting of system is similar to the described situation with reference to Figure 19 under this situation.

With reference to Fig. 1, the browser 210 that is used for browsing/show any html document that is stored in Web server terminal 11 is installed in the client terminal 21.

Web server terminal 11 comprises login authentication processing section 12, demonstration control and treatment part 13, Data Update processing section 14, monitoring of tools processing section 15, reaches information storage part 16.

Specifically, information storage part 16 storage is used for the log-on message file of each user log-in authentication and the storage user profile file about each customer management information and various html documents.

Response is by the register of client terminal 21, and login authentication processing section 12 is with reference to predetermined log-on message file and carry out corresponding authentification of user login.

Response is from the browse request of client terminal 21, shows that control and treatment part 13 reads the document of request and have only when the demonstration of document or change are allowed to and just it is distributed from information storage part 16.

Data Update processing section 14 changes the content that is stored in the predetermined file in the information storage part 16 according to the data from client terminal 21 inputs.

Be used for constituting the equipment of building service, for example air conditioner 31, temperature sensor 32, illuminating equipment 33 and elevator 34, the controller 30 that carries out centralized management is by being connected to Web server terminal 11 such as predetermined communication line such as LAN cable or telephone wire.

Monitoring of tools processing section 15 communicates according to steering order and the controller 30 from client terminal 21, thus the predetermined equipment of supervision/control.

The operation that will carry out when user arbitrarily will browse predetermined html document in the Web server terminal as first embodiment of the present invention explanation hereinafter with reference to Fig. 2.

Fig. 2 represents the process of document browsing.

In the html document browse operation, required html document is distributed to client terminal 21 according to process shown in Figure 2.

At first, the user carries out register by the 210 input the user name and passwords of the browser in the client terminal 21.

Suppose that the user name and password is that the pieces of information that the user has only also is recorded in the Web server terminal 11 in advance.

Respond this operation, the login authentication processing section 12 beginnings login authentication shown in Figure 3 of Web server terminal 11 is handled.

At first, login authentication processing section 12 check is corresponding to from the existence of the log-on message file of this user name of client terminal 21 inputs/do not exist (step 121).

How Fig. 5 supporting paper is stored in information storage part.

In this case, being provided with user management catalogue 51 in data file content 50, is the more low-level catalogue of unit setting with company, department, user, forms the structure of layering like this.

In user management catalogue 51, the catalogue 52B of the catalogue 52A of the A of company, the B of company ... be to be the catalogue that unit is provided with the company.

For example, the A of the company catalogue 52A of these company's catalogues comprises the company information file 53 of indication about the management information of the A of company, and also comprising with the department is the catalogue that unit is provided with, the A of department catalogue 53A, the B of department catalogue 53B ...

In addition, for example the catalogue 53A of the A of department of these department's catalogues comprise indication about the department information file 54 of the management information of the A of department and comprise with the user who belongs to this department be the catalogue that is provided with of unit user A catalogue 54A, user B catalogue 54B, user C catalogue 54C ...Each indication about the user profile file 55A of the user's of correspondence management information, 55B, 55C ... be stored in respectively with user is in the catalogue of unit setting.

In user management catalogue 51, login management catalogue 56 also is set to wherein store the catalogue that is used for login authentication information.

In this login management catalogue 56, login name 1 catalogue 57A, login name 2 catalogue 57B ... be set to login the catalogue that unit by name is provided with.Indication corresponding to log-on message file 58A, the 58B of the management information of each login name ... be stored in respectively with in the catalogue of logining unit by name setting.

Note, when login directory, will by company code, division code, personal code work, and the title of the character string formed of login name be assigned to these catalogues corresponding to company, department, user and login name.

Fig. 6 illustrates how the log-on message file is write as.In this file, code and his/her personal code work of user have been logined corresponding to company under the user of each login name and department.Note the field scope indication comment section (repetition) of end from symbol " # " to row.

Thereby, according to login name from client terminal 21 inputs, the login authentication processing section 12 of Web server terminal 11 is with reference to login name catalogue corresponding in the login management catalogue 56, so that check is corresponding to the existence of the user's who carries out register log-on message file/do not exist (step 121).

If find log-on message file (YES in the step 121), then obtain company, department, reach personal code work (step 122) from the log-on message file.

Then by with reference to by the directory verfication of these codes indication corresponding to the existence of this user's user profile file/do not exist (step 123).

If find user profile file (YES in step 123), then login authentication processing section 12 from the user profile file obtain password (step 124) and relatively this password with when the register from the password (step 125) of decoding circuit 21 inputs.

If two passwords are consistent each other, determine that then the user who has carried out register authorizes the user who logins, and send the menu page (step 126) that is used to select viewed html document to client terminal 21.

In this case, the user totem information of being made up of the company, department and the personal code work that obtain in the above-mentioned steps 122 is attached on the html document of indicating menu page and distributes to client terminal 21, termination sequence like this.

The additional user identification information of being made up of company, department and personal code work uses subsequently when the browse request that sends from client terminal 21 predetermined html document the time.

Notice that the function that is called " Cook (Cookie) " can be used to these codes of transmission/reception.

" Cook " is to transmit predetermined message file and it is stored in the information conversion function of client terminal to client terminal from the Web server terminal.It is first-class that this function is added on browser.

In this case, each code and corresponding encryption key are bonded to each other, and change a plurality of combinations in case of necessity.

Suppose to determine that in step 121 the log-on message file does not find (NO in the step 121), determine that in step 123 the user profile file does not find (NO in the step 123), or determine two passwords inconsistent each other (NO in the step 125) in step 125.In this case, determine that register is not have the user of registration to carry out by certain, and return the information (step 127) of indicating logon error, termination like this as the response that makes mistakes to client terminal 21.

When register normally carries out, be used to select the menu page of viewed html document to be presented at the screen of client terminal 21 by browser 210.

Simultaneously, the user totem information of receiving is stored in the client terminal 21.

When the required html document of browsing was selected on client terminal 21, browser 210 was sent to Web server to the URL that is used for the browse request html document, thereby produced browse request.

At this moment, receive and in advance the storage user totem information be attached in the request.

Respond this request, the demonstration control and treatment part 13 beginnings demonstration control and treatment shown in Figure 4 of Web server terminal 11.

At first, show whether control and treatment part 13 inspection user identification informations are attached on the browse request of receiving (step 131).

If determine to have added user totem information (YES in the step 131), then show control and treatment part 13 with reference to the catalogue in the information storage part 16 of indicating, and open the user profile file (step 132) that is provided with corresponding to the user in advance by the user's who constitutes user totem information company, department and personal code work.

Show that then control and treatment part 13 obtains to produce from the user profile file the user's of browse request access level (access right), and whether check allows demonstration and change (step 133) corresponding to the document of this browse request.

If determine to allow the demonstration and the change (YES in the step 133) of document, show that then control and treatment part 13 reads corresponding to distributing to client terminal 21 (step 134) from the html document of the browse request of information storage part 16 and with it, like this termination sequence.

If step 131 is determined user's company, department and personal code work not additional (NO in the step 131), or in step 133, determine not allow display document (NO in the step 133), show that then control and treatment part 13 definite browsing of html document of being asked are under an embargo, and return the information (step 135) of indication browse request mistake, termination like this as the response that makes mistakes to client terminal 21.

Thereby, to show or change user profile if having other user of scheduled visit level, i.e. user profile file, the then browse request that produces the html document that presents the user list window of the browser 210 of client terminal 21.Respond this request, the demonstration control and treatment part 13 of Web server terminal 11 is carried out following definite processing.

Suppose described each message file with reference to Fig. 5, promptly company information file 53, department information file 54 and user profile file 55A, 55B, 55C ... storage is about the keeper's that manages corresponding company, department and user profile file information.

For example, in company information file shown in Figure 7, except exabyte, so that management belongs to the various information file of the said firm, promptly be stored in keeper's name of the various information file in each catalogue under company's catalogue etc. with having sufficiently high access level.

In addition, the information of the particular type authority that is had with indication company as company's attribute.

In this case, with building management company or suitable company, Web server terminal service companies, and the facility A of indication company correspondence is to the information of one of specific management company of E with the form of " true/vacation ".

Similarly, in the department information file for example shown in Figure 8, except department's name, so that management belongs to the various information file of this department, promptly be stored in keeper's name of each message file in each catalogue under department's catalogue etc. with having sufficiently high access level.

In addition, the information of the particular type authority that is had with indication department as department's attribute.

In this case, with building management company or suitable department, Web server terminal maintenance department, and the facility A of indication department correspondence is to the information of one of specific administrative authority of E with the form of " true/vacation ".

For example, in the user profile file shown in Figure 9, except login name and password, also with user name etc.

In addition, as the information of user property with the special delegated authority type of indicating the user to have.

In this case, with the form of " true/vacation " keeper, company management person, department manager with building management person, Web server terminal maintainer, facility A to E, and indicate the information to one of the specific access level of E corresponding to general user A.

Significantly, under this situation, this user is general user A to the keeper of E and has the mandate of the user profile file that changes these users.

The maintainer who supposes building management person and Web server terminal has sufficiently high access level, and can show or change all segments that are recorded in user profile in this system.

Suppose that company management person has all segments that sufficiently high access level can show or change the user profile that belongs to the affiliated the said firm of this keeper, and the department manager have all segments that sufficiently high access level can show or change the user profile that belongs to this affiliated department of this keeper.

Thereby, when the browse request that produces the html document that presents the user list window, show control and treatment part 13 with reference to the user profile file that has produced the user of browse request, and the access level of inspection user (referring to the step 133 among Fig. 4).

Have the identical access level of building management person with the maintainer of Web server terminal if produced the user of browse request, all segments of then determining to be recorded in the user profile in this system can be shown or change.

When this is determined, as the user list window, produce and return (step 134 among Fig. 4) selection of all segments of being recorded in the user profile in this system is presented the html document of menu page to the browser 210 of client terminal 21, for example be used to select the A of company, B ... menu page.

If the user has the access level identical with company management person, then as the user list window, produce and return the html document of the menu page of all segments that present the user profile that is used to select only to belong to the said firm, for example be used to select the A of company the A of department, B ... menu page.

Similarly, if the user has the access level identical with the department manager, then as the user list window, produce and return the html document of the menu page that presents all segments of user profile that are used to select only to belong to this department, for example be used to select the A of department user A, B, C ... menu page.

In addition, if the user has visit specific user's sufficiently high access level, then as shown in Figure 9, produce and return to present as the user list window and be used to select only about the menu page of general user A to the user profile of E.

If the user does not have these access levels, that then returns indication user list window browses forbidden html document (step 135 among Fig. 4).

As mentioned above, in the present embodiment, when the browse request that produces from client terminal 21 predetermined html document, the demonstration control and treatment part 13 of Web server terminal 11 is obtained access level from the user's of client terminal 21 user profile file, and determines whether to allow to show and change the html document of user's request based on this access level.Have only when allowing demonstration and changing document, just distribute the html document of being asked.

Thereby this system can be according to user's the accurately permission of management document of access level/forbid, and forces same user selectively to use the loaded down with trivial details operation of a plurality of login names need not to resemble in the prior art.

In addition, owing to produce and only distribute by the new html document that indication allows/forbid to show or the information that changes is formed, so can not on the screen of client terminal 21, show the information of be under an embargo demonstration or change according to each user's access level.Forbid information when demonstration, for example be used for when visiting the choice menus of forbidden document that this can prevent that user error from understanding to its visit.

In addition, owing to selecting user profile file corresponding to browse request based on form and be attached to identification information that the user in the request has only by company, department and personal code work, even in WWW, wherein when the visit carried out from client terminal 21 to Web server terminal 11, disconnect, also need not authentification of user is carried out in each visit.This can reduce connection processing.

In addition, before the browse request that is producing document according to register by client terminal, carry out given user's login authentication, and make when authenticating, transmit the user totem information that is attached in the document browsing request.Thereby Web server terminal 11 can manage this user totem information, so can suppress unauthorized visit.

Note in the above description, when user authentication information when login authentication processing section 12 is transferred to client terminal 21, the term of validity of this user totem information can be managed.

For example, if according to the permission/forbid of login determine to transmit user totem information, then the term of validity of user totem information is set to indefinite.

When after this user nullifies, transmit the user totem information that its terms of validity are zero (relative time) from login authentication processing section 12 to client terminal 21.

Use this operation, only can make the user totem information of preserving by client terminal 21 effective in the time interval between register and cancellation operation, thereby improved the reliability of system.

Below, be used to monitor operation that the various device of forming building service will carry out with reference to Figure 10 explanation by client terminal as the second embodiment of the present invention.

Figure 10 represents to show another example of control and treatment, and particularly wherein asks the situation of the html document of display device list window.

When predetermined equipment wanted monitored, the user used the browser 210 of client terminal 21, produced the browse request to the html document that presents the list of devices window that is used to select monitored equipment.

Demonstration control and treatment part 13 these requests of response of Web server terminal 11, the demonstration control and treatment shown in beginning Figure 10.

The user who shows control and treatment part 13 inspection users represents information, and promptly whether user's company, department and personal code work are attached on the browse request of receiving (step 151).If user totem information is not attached to (NO in the step 151) on the browse request, show that then control and treatment part 13 returns the document (step 168) that the HTML of browsing apparatus list window is forbidden in indication, termination like this as the response that makes mistakes.

If user totem information is attached to (YES in the step 151) on the browse request, show that then control and treatment part 13 situation as shown in Figure 4 opens the stored user information file (step 152) according to company, department and personal code work.

Show the company code of control and treatment part 13 then according to the user totem information of receiving, open the common equipment message file (step 153) that is provided with corresponding to the company under the user, and the list information of opening corresponding to the setting of user affiliated function according to division code is provided with file (step 154).

Figure 11 represents another file storage state in the information storage part.Identical label is represented the parts (referring to Fig. 5) identical with previous explanation among Figure 11.

Under this situation, in each catalogue that with the company is the unit setting, facility information catalogue 61 is set, for example, the A of company catalogue 52A.Indication belongs to the equipment that the user of the A of company can supervise/control, promptly to the disclosed equipment of the user of the A of company, common equipment message file 62 be stored in the facility information catalogue 61.

It is in each catalogue of unit setting that the facility information catalogue also is arranged on the department, for example the A of department catalogue 53A.Each user that each indication belongs to the A of department to the list information of per unit access level be provided with file 64A, 64B ..., be stored in the facility information catalogue.

Figure 12 illustrates how the common equipment message file writes out.

In this file, as write on shown in the form of each row on first row, the user who is used to specify the title of the management point code of management number, equipment of equipment and equipment (management point) and belongs to company writes out in proper order to the access level of this equipment first row from each row.

As access level, be provided with visit and allow rank (R: read), operation to allow rank (W: write), and show that (operation) forbid rank (-).

Figure 13 has illustrated that list information is provided with file and how writes out.

In this case, shown in the form that each row is gone up each row, be used for specified devices and department manager the management number of the access level of equipment is write out in proper order from first row on each row.Each user (user A is to E) writes on after department manager's the access level the access level of equipment.

Notice that list information is provided with each page setting of file corresponding to the list of devices window.For example, the access level that is presented at the equipment on first page of the list of devices window being write on list information is provided with among the file 64A.Be provided with among the file 64B at list information, write out corresponding to the access level that is presented at the equipment on second page of list of devices window.

Thereby demonstration control and treatment part 13 is opened the common equipment message file 62 of the affiliated company of user, with for the list information of the page of the list of devices window of its generation file is set corresponding to browse request, for example list information is provided with file 64A (step 152 and 154).

Showing then that control and treatment part 13 is relatively tabulated writes on list information in access level among the information setting file 64A and the common equipment message file 62 per unit access level among the file 64A is set, and uses lower access level as the access level (step 155 to 163) of user to this equipment.

Show that control and treatment part 13 search listing information setting file 64A seek not processed facility information (step 155).Find not processed equipment (YES in the step 155), showing the segment information (step 156) that control and treatment part 13 is read about this equipment.

If show the information (YES in the step 157) that control and treatment part 13 is successfully read about this equipment, part 13 is with the access level of variable X storage user for this equipment, and this rank is provided with among the file 64A at list information (step 157) is set.

Then, to the access level that is arranged on the equipment in the common equipment message file 62 with variable Y storage (step 157), and among access level X and the Y rank low with variables A storage (step 158).

Show control and treatment part 13 test variable A (step 161) then.If variables A is " W ", show that then control and treatment part 13 users are set to " operation allows (change and allow) rank " (step 162) to the access level of this equipment.Flow process is returned step 155 then.

If variables A is " R ", show that then control and treatment part 13 users are set to " show and allow rank " (step 163) to the access level of this equipment.If variables A is "-", show that then control and treatment part 13 users are set to " (attendant exclusion) rank is forbidden in demonstration " (step 164) to the access level of this equipment.Flow process is returned step 155 then.

If determine read fail (NO in the step 157), show then that control and treatment part 13 is provided with to read end (step 165) to what list information was provided with file 64A about the information of equipment in step 156.Flow process is returned step 155 then.

When list information is provided with untreated facility information among the file 64A by this sample loading mode sequential processes, and when step 155 determines not stay untreated facility information (NO in the step 155), show that access level that control and treatment part 13 slave controllers 30 obtain users allows list information that the demonstration among the file 64A or the state (step 166) of apparatus operating are set to it.

Show control and treatment part 13 states then based on each equipment that is obtained, form new html document, the document presents indication and allows the list window of user to its demonstration or apparatus operating, and document is turned back to client terminal 21 (step 167), like this termination sequence.

In this case, about having been determined, it shows that per unit information of forbidding does not write in the new html document.

In addition, if it has been determined beginning/end point or the set-point of the equipment of operation permission corresponding to the buildings supervisory system, the hyperlinked information that then is used for call operation window (html document) searching operational order writes on new html document.

About the equipment of it having been determined demonstration (operation) is forbidden, this hyperlinked information does not write.

Suppose when the browse request that produces by user C this list window, common equipment message file shown in Figure 12 and list information shown in Figure 13 to be set file is set.In this case, have only equipment 1 " air conditioner 1 " to be operated, and corresponding information and hyperlinked information together show.

An example is exported in the demonstration of Figure 15 indication equipment list window.With reference to Figure 15, the real underscore indication of " air conditioner 1 " in the device name row has added hyperlinked information.The user can call the action pane that is used for " air conditioner 1 " by clicking this part.

In addition, the demonstration of permission equipment 3 " air conditioner A " and equipment 7 " light fixture 1 ", and corresponding information need not any hyperlinked information and is shown.

In this case, dashed underline (or not having underscore) indication of " air conditioner A " and " light fixture 1 " does not have hyperlinked information in the device name row.

Notice that it is forbidden that the demonstration of equipment 2 " air conditioner 2 " and equipment 6 " are shared air conditioner ", and do not have corresponding information to show.

As mentioned above, in the present embodiment, inspection user is to per unit access level, and is used for changing the html document information of window of mode of operation that it is allowed the equipment of operation (promptly changing) presenting, for example hyperlinked information adds in the corresponding information.Thereby the user can call the action pane that allows apparatus operating immediately by the list of devices window that obtains.

On the list of devices window that shows at browser 210 by client terminal 21, when the user was used for the html document of operation of equipment window to a device request that allows operation, the demonstration control and treatment part 13 of Web server terminal 11 started the demonstration control and treatment shown in Figure 16 A or the 16B.

Figure 16 A and 16B represent to show other example of control and treatment.Figure 16 A represents wherein to ask the generalized case to the action pane of any apparatus.Figure 16 B represents wherein to ask " elevator " presented the situation of the html document of action pane.The process of this processing is almost with shown in Figure 4 identical.

Referring to Figure 16 A, at first as the URL of operation of equipment window request reception corresponding to the html document of requested operation of equipment window.If the user totem information about the user appends to (YES in the step 171) in this request, then show control and treatment part 13 each code based on user totem information, open user profile file (step 172), and check general user A is to the access right (step 173) of E corresponding to the user.

If user capture rank and the general user A that equipment is provided with of user property that file is set based on list information is to the access level of E consistent (YES in the step 174), show that then control and treatment part 13 reads html document by the URL that receives indication from information storage part 16, it is the html document of display device action pane, and it is returned (step 175), termination sequence like this.

Note, each facilities and equipment are corresponded to each other in advance.

Though not shown among Figure 18, the client computer 80 in other office is connected to interior of building network 77 in the same manner described above.

Server computer 78 comprises server program.Each client computer 80 comprises the general browser program, thereby can pass through interior of building network 77 access server computing machines 78.

In this case, these client computers 80A and 80B are corresponding to the client terminal among Fig. 1 21, and server computer 78 is corresponding to the Web server terminal 11 among Fig. 1.

According to transmitting the request browse request of predetermined html document (promptly to) from the information of client computer 80, server computer 78 determines to the demonstration of the user institute information requested (html document of request) of client terminal or changes whether be allowed to/forbid according to client terminal user's access level.Have only when allowing demonstration or changing, server computer 78 could transmit information requested to the user.

In addition, in this building management system, all client computers 80 are distributed in this buildings.

Each floor that if the lessee is A, the office of B, C and dining room have occupied this buildings, then client computer 80 is installed in these offices.

Each lessee can be on the display of client computer 80 state of monitoring preset equipment 71.

Each lessee can carry out the setting/change of ON/OFF operation or temperature, humidity etc. to predetermined equipment on the display of client computer 80.

The characteristic operation of this building management system below will together be described with the function of client computer 80 and server computer 78.

At first, the user in the office of lessee A starts the browser program among client computer 80A and the 80B, so that transmit request by interior of building network 77 to server computer 78 output informations.

Server program in the server computer 78 starts then, so that the current state information at each management point place of collecting and write down by central monitoring equipment 74, form html document, and send it to each client computer 80A and 80B by interior of building network 77.

Each client computer 80A and 80B show the current state information of each management point that sends from server computer 78 on display.

In this case, ask after the current state information at each management point place in the information transmission that has transmitted corresponding to from each client computer 80A and 80B, browser program among each client computer 80A and the 80B and the communication between the server program in the server computer 78 are interrupted.

Therefore, be presented at the status information at each the management point place on the display of each client computer 80A and 80B, send before next information transmits request, can not be updated up to the user.Thereby the user can not know in real time that the state of each management changes.

Yet present embodiment allows the user to monitor the status information at each management point place in real time by server computer 78 on each client computer 80A and 80B.

User in the office of lessee A starts the browser program among each client computer 80A and the 80B, so that transmit request by interior of building network 77 to server computer 78 output informations.

When receiving this information request, server program in the server computer 78 passes through interior of building network 77 to each client computer 80A and 80B, sends the current state information at each management point place of being collected and write down by central monitoring equipment 74 as initial display message.

Browser program among each client computer 80A and the 80B shows the initial display message from server computer 78 on display.

When receiving initial display message, each client computer 80A and 80B be to server computer 78, together sends the key message that changes the management point of notice from its solicited status with the status information of the current demonstration at management point place.

When receiving these pieces of information, server computer 78 obtains by the current state information on the management point of each client computer 80A and 80B appointment (changing notice from its solicited status).

Information that server computer 78 is relatively obtained and the current shown and status information that sends, and if the current state information that is obtained be different from the status information of current demonstration, determine that this management point is for through the management point of state change.Server computer 78 calculates 80A and 80B transmission management information to each client then.

In addition, when server computer 78 initiatively accepting states change notice the time, computing machine 78 is similarly handled.More particularly, if change the management point of notice from its active accepting state by building management dedicated network 76, with consistent by the management point of each client computer 80A and 80B appointment, then server computer 78 transmits corresponding status information to each client computer 80A and 80B.

When the status information of receiving about the management that changed through state, each client computer 80A and 80B with the status information received as current state information, the display message on the refresh display.

Each client computer 80A and 80B repeat this operation to be stopped up to browser program.

By this operation, be presented in real time on the display of each client computer 80A and 80B about the current state information of the management point of appointment.

Though server computer 78 only sends status information about the management point of the appointment that changed through state to each client computer 80A and 80B, but server computer 78 can send the current state information of the management point of all appointments to each client computer 80A and 80B, no matter and the existence that state changes/do not exist.

In other words, can be presented at continuously on the display of each client computer 80A and 80B, no matter and the existence that state changes/do not exist about the status information of the management point of all appointments.

By only sending status information about the management point of the appointment that changed through state, promptly only send assignable status information, can reduce the load of interior of building network 77.

In addition, though the user wishes management point that announcement server computing machine 78 states change by client computer 80A and 80B appointment from it, all management points can be set to the target that can change from its notify status, and need not to specify any management point.

By specifying management point, the status information of nonessential management point need not to send to client computer 80A and 80B.This has reduced the load of interior of building network 77.

Note, when not specifying management point, can send status information, no matter and the existence that state changes/do not exist about all management points.

In addition, according to above explanation, till being connected the browser program that is held among client computer 80A and the 80B and stopping between client computer 80A and 80B and the server computer 78.Yet each client computer 80A and 80B can be only be connected (under this situation, carrying out from server computer 78 being connected to each client computer 80A and 80B) with server computer 78 when some management point changes through state.

Use this technology and since connection procedure required the time chien shih status information the real-time characteristic of transmission worsen.Yet this technology is compared almost with promotion technology (repeating to produce the automatic distribution technique of information transmission request automatically) can be considered as real-time technique.

According to above-mentioned the 3rd embodiment, by using each client computer 80A and 80B browser program, be presented on the display from the current state information about each management point of server computer 78.

Because the restriction of communication protocol and universal program, for exchange message may need complicated operations, or necessary information may be can't see yet in this case.

Therefore, when reception was asked from the information transmission of each client computer 80A and 80B, server computer 78 sent the special software (status information browsing software) that is used to browse each management point status information in the buildings to each client computer 80A and 80B.

In this case, each client computer 80A and 80B be from server computer 78 download status information browsing software, and by using the status information browsing software of downloading on display, to show the current state information about each management point from server computer 78.

Use this operation, simplified the exchange of information, and can on the display of each client computer 80A and 80B, see current state information, even use also failsafe of different communication protocol about each management point from server computer 78.

In this case, the status information browsing software is sent to each client computer 80A and 80B from server computer 78.Yet the user can install this software in each client computer 80A and 80B.

If update mode information browse software, new status information browsing software must send to the user of each client computer 80A and 80B so that reinstall yet in this case.

In contrast, if the status information browsing software sends to server computer 78, this software must send to the user of each client computer 80A and 80B and install, and can be easy to upgrade status information browse software.

In the above description, the current state information of each management point in each client computer 80A and 80B monitor about buildings.Yet for example setting/the change of ON/OFF operation and temperature, humidity etc. can be carried out from each client computer 80A and 80B predetermined equipment 71.
