Description of the Invention: [Technical Field of the Invention] The present invention relates to a server that integrates logins from a client computer into an portal server system of an portal server (Portal Sever) and an portal server server system. Access method. [Prior Art] In the past, we have a system for managing various devices such as air conditioners, fire-fighting equipment, anti-theft devices, and lighting equipment in facilities such as rental apartments, hospitals, and public facilities. And because of the increasing number of complex facilities, large-scale systems for the unified management of multi-function buildings, rental apartments, commercial facilities, homes, hotels, and many other buildings are increasing. In such a large-scale system, since the amount of information managed is large, it is necessary to effectively support the operator's daily maintenance business. For example, in Patent Document 1, a description is given of a list of "Days® Job Contents", "Day of Failure Response", "When stocking supplies, consumption" are displayed on the entrance screen of the client computer. As the item related to the work performed on the current day, the product usage status is displayed together with the result of the statistical processing of the fault response status and the work status, and the button for confirming the detailed information by the one-button operation is set, so that the segmentation operation is not required. It is easy to display the desired screen and confirm the device information. In this case, in order to decentralize or redundantly process the functions, it is conceivable to set a plurality of servers on the network to concentrate the logins from the client computers on the portal server. Fig. 12 and Fig. 13 show an example of the fifth example and the second example of the portal server system in which the login from the client computer is concentrated on the portal server server of the present invention. [1st example (no duplexing)] In Fig. 12, M is the client computer, 2 is the network, 3 is the i-th server (hereinafter referred to as the feeder C), and 4 is the second server (hereinafter referred to as The server A) and 5 are the third server (hereinafter referred to as the server B). The client computer 1 and the servers A, B, and C are connected to each other through the network 2. In the first example, the server A has an entry site function for the server B, and the server C has an entry site function for the server A. That is, the client computer 1 can use the function of the server b by using the server A as the portal server and logging in to the server A, by feeding the server c as an entry site | Server C, that is, the function of server A can be used. In order to realize the portal function, the address #B of the server B is registered in the server a, and the address #8 of the server A is registered in the server C. [Second example (with duplexing)] In Fig. 13, a server 5-1 (hereinafter referred to as server B 1 ) of the processing system and a server 5-2 of the standby system are provided as the server B (below) Called server B2). The client computer 1 and the servers A, B1, B2, and C are connected to each other through the network 2. In the second example, the server A has an entry site function for the servers B1 and B2, and the server C has a server for the server. A's portal feature. That is, the client computer 1 can use the function of the server B1, B2 by using the server A as the portal server and logging in to the server A, by using the server 200937213 as the portal server. And log in to server c, you can use the function of server A. In order to realize the portal function, the addresses B1 and #b2 of the servers B1 and B2 are registered in the server A, and the address #A of the server A is registered in the server C. Further, the server a has a normal check function for periodically checking whether communication with the servers B1, B2 can be performed. In the second example, when the client computer 1 of the server a is determined to be able to perform communication with the server B1 of the processing system by the normal check function of the server A, the servo of the processing system is used. When the function of the device B1 determines that communication with the server B1 of the processing system cannot be performed, but communication with the server B2 of the standby system is possible, the function of the server B2 of the standby system is used. . [Patent Document 1] JP-A-2002-312455 SUMMARY OF INVENTION However, in the above-described portal server system, when it is desired to use the function of the server A, it is necessary to log in to the server C, in the hope When using the function of the server B (B Bu B2), it is necessary to log in to the server A, and the functions of the servers A and B (B1, B2) cannot be used without interruption. In this case, it is desirable to log in only by the server. C, you can use the function of server A and the function of server B (B1, B2). In other words, it is desirable to use the server C as the upper portal server, and the functions of the servers A and B (B1, B2) can be used without interruption by registering only the upper portal server.

In response to such a request, the applicant of the present invention conceived a way of accessing the server B (B1, B2) from the server C through the feeder A using the portal function of the server A 7 200937213 (method 1) . Further, the address of the server B (Bb B2) is set in the server C, and the server b (B1, B2) is accessed from the server C (method 2). However, in the first aspect and the second aspect, the following problems exist. Next, the problem in the case where the mode 1 is employed in the first example of the portal server system described above will be described with reference to Fig. 14'. In the first example of the portal website server system using the shai mode 1, the client computer 1 'when logging in to the server C' requires access to the server B, the portal function of the server A is utilized. The server B is accessed from the server c via the server a. In this case, if the server a is turned off, the function of the server B cannot be used, and thus there is a problem that the operation rate is lowered. Next, a problem in the case where the mode 2 is employed in the first example of the portal server system described above will be described with reference to Fig. 15. In the first example of the portal server system using this mode 2, the address B of the server B is set in the server port. If the client computer i requests to access the server B after logging in to the server C, the server B is accessed via the server C according to the address #B set in the server port. In this case, the function of the server B can be used even if the server A is turned off, but the address B of the server B must be registered in the server C. Next, a problem in the case where the square < 1 is employed in the second example of the portal server system described above will be described with reference to Fig. 16 . In the second example of the portal server system using the method 1, the client computer 1 requests access to the server b (bi, b2) after logging in to the server c, and 200937213 uses the server A. The portal function accesses the server b (B1, B2) from the server C via the server A. At this time, when the client computer 1 determines that communication with the server B 1 of the processing system is possible by the normal check function of the server A, the server B1 of the access processing system determines that the server B1 cannot be performed. When communication with the server B 1 of the processing system is performed, but communication with the server B2 of the standby system is possible, the server B2 of the standby system is accessed. In this case, if the server A is turned off, the function of the server B (B1, B2) cannot be used, and thus there is a problem that the operation rate is lowered. Next, the problem in the case where the mode 2 is employed in the second example of the portal server system described above will be described with reference to Fig. 17'. In the second example of the portal server system using this method 2, the addresses B1 and #B2 of the servers B1 and B2 are set in the server C. Moreover, a normal inspection function for the servers B1, B2 is provided in the feeder C. If the client computer 1 requests to access the server B (b1, B2) after logging in to the server C, the server is accessed via the server c according to the addresses #B1 and #B2 set in the server C. B (B, B2). At this time, when the client computer 1 determines that the communication with the server B 1 of the processing system can be performed by the normal check function of the server C, the server B1 of the access processing system determines that it cannot The communication with the feeder B1 of the processing system is performed 'but the communication with the server B2 of the standby system is enabled', and the server B2 of the standby system is accessed. In this case, 'Although the servos B 1 and B 2 can be used even if the feeder A is turned off, the address of the feeding device b 1 and b 2 9 200937213 must be registered in the 4 server C. #B1, #B2. In addition, it is necessary to add a normal inspection function to the feeding machines Bl and B2 in the feeding device c. The present invention has been made to solve the above problems, and an object of the present invention is to provide an portal website feeder system capable of avoiding unnecessary address registration and function addition to a superior population website server and achieving a sufficiently high operation rate. And the server access method of the portal server system. In order to achieve such an object, the portal server system of the present invention (first invention) includes an i-th server, and the address is registered in the second server of the i-th server, and the address is registered in the address server. The third (five) server of the second server and the client computer that uses the first server as the portal server and accesses the second and third servers through the network, characterized in that the client computer has 1 2 server address acquisition means, when logging in to the portal website, the device obtains the address of the second server registered in the portal server; the third feeding device address acquisition means 'according to the second The address obtained by the feeding device address acquisition means accesses the f 2 feeding device, and acquires the address of the third feeding device registered in the second server; and the third feeding device access means, login When the third server is requested after accessing the portal server, the third feeding device is accessed based on the address obtained by the third feeding device address obtaining means. According to the first aspect of the invention, the j-th feeding device is set as the portal site feeding device (the upper portal server) c, the second feeding device is the server A, and the third feeding device is set. In the case of the feeder B, when the client computer logs in to the portal server c, the address A of the server A registered in the portal server c is obtained. Then, according to the obtained address #人访问服务10 200937213器 A', the address of the server B registered in server A of the server A is obtained. If the client computer is registered to the portal server c, it is required to be stored. When server B is taken, server b is accessed based on the obtained address B of server B. As can be seen from the above operation, in the first invention, since the client computer acquires the address #B of the server 8 from the server a when logging in to the portal server C, after logging in to the portal server c, Even if the server a is turned off, the server can be accessed from the client computer and the address b of the server b does not need to be registered in the portal server C. Further, in the first invention, the client computer, when logging in to the portal server C and requesting access to the server B, can directly access the address B of the server B obtained. Server B, but after confirming whether communication with server A or server B is possible, server B can be accessed based on the obtained address B of server B. In addition, in the first invention of the sho, the portal server (server C) may include: a second server capable communication check means, and periodically check whether or not the second server (server A) is performed. And the second server communication recovery notification means, when it is determined that communication with the second server that is determined to be incapable of communication with the second server availability communication check means is possible The status of the communication with the second server is notified to the client computer; the client computer has: the third server address re-acquisition means, and the second server communication recovery notification on the portal server When the means notification is restored to the state in which communication with the second server is possible, the second server is accessed based on the address acquired by the second server address obtaining means, and the second server is acquired and registered. 11 The address of the third server (server b) of 200937213. By providing such a means, for example, when the address #Bnew of the new server Bnew is registered in the server A and the server a is restarted, it is possible to temporarily fail to communicate with the server a. When the status of the communication between the servers A is 'enabled', the client computer can again obtain the address #Bnew of the new server Bnew registered in the server A. Further, the portal server system of the present invention (second invention) includes a first server, and the address is registered in the second server of the first server, and the address is registered in the processing system of the second server. The third server registers its address in the third server of the standby system of the second server, and uses the first server as the portal server and accesses the second and third servers through the network. The client computer is characterized in that: the portal server has a second server capable communication check means, and periodically checks whether communication with the second server is possible, and notifies the client computer of the result of the check; The second server includes: a third server capable of communication check means, and periodically checks whether communication with the third server of the processing system and the third server of the standby system is possible; the client computer has: 2nd Server ◎ address acquisition means, when logging in to the portal server, obtaining the address of the second server registered in the portal server; 帛3 server address obtaining means, based on the second server address Get a hand The address obtained by the segment accesses the second server, and acquires the address of the third server registered in the processing system of the second server and the third server of the standby system; and the second server can determine the communication means. After logging in to the portal server and requesting access to the third server, based on the result of the check of the communication check means from the second server of the portal server 12 200937213, it is determined whether or not the server can be connected to the server. Between the IttFd 2 feeding service||Communication may be the third ship access means 'in the second feeding machine can be in; the supplement * * α sitting 丨 mail $ 』 communication judgment means judged to be able to

When the second server communicates with each other, the second feeding device is accessed based on the address obtained by the second feeding device address obtaining means, and the third server can be used to check whether or not the third server can communicate with each other. As a result of the inspection, when the inspection result indicating that communication with the third server of the processing system is possible is obtained, the third feeding device of the address access processing system acquired by the third server address obtaining means is obtained. When the communication result indicating that communication with the third feeding device of the processing system cannot be performed, but the communication with the f 3 (five) server of the standby system can be performed, 'according to the 帛3 servo ϋ address acquisition means The third server of the address access standby system; and the third server access means of the second server communication non-month t· is determined to be impossible to perform in the second feeding device communication determination means通讯2 The communication between the feeders is based on the address obtained by the third server address acquisition means to access the third server of the processing system. According to the second invention, the third server is set to the server A, and the third server of the processing system is set to the servo, the third server is used as the server (the upper portal server) c. When the third server of the standby system is set to the server B2, the client computer acquires the address of the server A registered in the portal server c when logging in to the portal server c. #A. Then, based on the obtained address #A access server A', the addresses B1 and #B2 of the servers B1 and B2 registered in the server A are acquired, and the client computer is registered to the portal server C. After that, it is required to access the server B (B1, B 2 ) and judge whether the communication with the server A can be performed based on the inspection result from the portal server. Here, if it is determined that communication with the server A is possible, the client computer accesses the server a based on the obtained address #A, and obtains whether or not the server A can perform with the feeder B. (B1, B2) The result of the communication check "When the inspection result indicating that communication with the server Bi of the processing system is available is obtained, the server of the processing system is accessed based on the acquired address 1. B1. When the communication result indicating that communication with the server B1 of the processing system cannot be performed, but the communication result with the server ❹ B2 of the standby system can be performed, the access is made based on the acquired address #b2. System feeding device B2. On the other hand, if it is determined that communication with the server A cannot be performed, the client computer accesses the server B 1 of the processing system based on the acquired address #bi. According to such an operation, in the second invention, since the client computer acquires the addresses #B1 and #B2 of the servers B1 and B2 from the server A when logging in to the portal server C, the login is performed. After accessing the server C, the server B (B1) can be accessed from the client computer even if the server A is turned off. In addition, it is not necessary to register the address of the service device Bi, B2 in the portal server c. #Β1, #Β2β In addition, it is not necessary to add the tester w and B2 in the word server c. The function of the possible state of communication (normal check function). In the case of the case, there are cases where the server A (the second server) and the server m (the third server of the processing system) are simultaneously shut down; (2) When logging in to the portal server c (14th 200937213 1 server), the server A (the second server) is not operating at all, but it is considered to be rare in the system. Cancel access. In the second invention, even in consideration of these circumstances, a sufficiently high operation rate can be realized. Further, in the second aspect of the invention, the portal server (server C) may include a second server communication recovery notification means, and it is determined that the second server is capable of communicating with the second server. When communication between the second server (server a) that was previously determined to be unreachable is notified, the status of the communication with the second server is restored to the client computer; the client computer has : The third server address re-acquisition means, when the second server communication recovery notification means of the portal server is notified that the communication with the second server is resumed, "based on the second server bit The address obtained by the address acquisition means accesses the second feeding device' and acquires the third server (server B1) registered in the processing system of the second server and the third server (server) of the standby system. b 2 ) The address of ❾. By providing such a means, it is possible to configure, for example, to register the addresses #mnew and #B2new of the new servers Blnew and B2new in the server A, and restart the server A, and then resume the operation. When the state of communication between the server C and the server A that has not been previously communicated is 'received', the client computer can acquire the addresses #Blnew and #B2new of the new servers Blnew and B2new registered in the server A again. The present invention can be implemented not only in the manner of an portal server system, but also in the manner of a server access method of an portal server system. 15 200937213 According to the present invention, when the client computer logs in to the portal server (the upper portal server), the address of the second feeding device registered in the portal server is obtained, based on the obtained The address is accessed by the second server, and the address of the third server registered in the second feeding device is acquired, and the third server is requested to access the third server even after registering to the portal server. 2 When the server is turned off, the third server can be accessed from the client computer, thereby avoiding unnecessary address registration and function addition to the upper portal server, and achieving a sufficiently high operation rate.

The client computer 1 logs into the portal server C based on the login request from the operator (Fig. 6: arrow (1)) (Fig. 6: arrow (2)). At the time of registration, the client computer acquires the address #A of the server A registered in the portal server c (Fig. 6: arrow (3)). Then, based on the address #A obtained from the portal server c, the server A is accessed, and the addresses #B1 and #B2 of the servers b1 and B2 registered in the feeder A are obtained (Fig. 6 : Arrow (4)). If the operator selects the function of server B after logging in to the portal server c (Fig. 6: arrow (5)), the client computer engineer asks server a whether it can perform with server B (B1, B2). Communication between (Figure 6: arrow (6)). Here, if the inspection result indicating that communication with the server of the processing system can be performed is returned from the server A (FIG. 6: arrow (7)), the client computer 1 deletes the address of the obtained server B1. , access the processing system's server B1 (Figure 6: arrow (1)). In addition, in the case of an abnormality, 'there is a return from the server A indicating that the communication with the feeder B1 of the processing system is not performed, but the result of the inspection of the communication with the server B2 of the standby system of 23 200937213 can be performed. Next (Fig. 6: arrow (11)) 'The client computer 1 accesses the server B2 of the standby system based on the obtained address #B2' of the server B2 (Fig. 6: arrow (12)). In addition, in the case of an abnormality, when the server A returns a check result indicating that communication with the server B1 of the processing system and communication with the server B2 of the standby system cannot be performed (FIG. 6: Arrow (15)) 'The client computer outputs an error message indicating that the connection failed to the operator (Fig. 6: arrow (16)). [After logging in to the portal server C, the server A becomes unable to communicate: Figure 7] The client computer 1 logs in to the portal server based on the login request from the operator (Fig. 7: arrow (1)) In c (Figure 7: arrow (2)). When logging in at shai, the client computer acquires the address #A (Fig. 7: arrow 3) of the server A registered in the portal server c. Further, the server A is accessed based on the address #a obtained from the portal server C, and is acquired. The addresses of the servers b 1 and B 2 in the feeder A are #B 1 and #B2 (Fig. 7: arrow (4)). 〇 Here, as a hypothetical situation, it may be considered that the server a becomes unable to communicate after logging in to the portal server C. In this case, the portal server C periodically checks whether it is possible to perform communication with server A. If it is determined that communication with server A is not possible (figure 'arrow (5)), then This is notified to the client computer 1 (Figure 7: Arrow (6)). Then 'If the operator selects the function of the server B (Fig. 7: arrow 24 200937213 (7)) 'the client computer 1 judges that it cannot be performed with the server A based on the notification result from the portal server c' Communication (Fig. 7: arrow (8)) 'According to the address 1 of the obtained server B1, the server B1 of the processing system is accessed (Fig. 7: arrow (9)). If the portal server C determines that communication with the previously unavailable server Λ is possible (Fig. 7: arrow (10)), the state of communication with the feeder Α is restored. Notify the client computer Figure 7: Arrow (11)). ❹ If the client computer 1 receives a notification indicating that the communication with the server A has been restored from the portal server c, the access is based on the obtained address A of the server A. The server A acquires the addresses #B1 and #B2 of the servers b1 and B2 registered in the feeder A (Fig. 7: arrow (12)). Then 'If the operator selects the function of the server B (Fig. 7: arrow (13))', the client computer 1 asks whether the server a can communicate with the servo q B (B1, B2) (Fig. 7: arrow (14)), if the inspection result indicating that communication with the server b 1 can be performed is returned from the feeder A (Fig. 7: arrow (15)), according to the obtained position of the server B1 Address #B1 'Access the server B1 of the processing system (Fig. 7: arrow (16)). For example, when the addresses #Blnew and #B2new' of the new servers Blnew and B2new are registered in the server A and the server a is restarted, communication with the server A is temporarily impossible. In such a case, the address #Blnew, #B2new of the new server Blnew, B2new 25 200937213 registered in the feeder A is restored to the state in which communication with the server A can be performed. Client computer! Further, the new server Bnew (B lnew, B2new) can be accessed based on the addresses #Blnew and #B2new of the re-acquired servers Blnew and B2new. [When server A cannot communicate when logging in to portal server C: Figure 8] Client computer 1 logs in to the portal server based on the login request from the operator (Figure 8: arrow (1)) : Medium (Fig. 8: arrow (2)). When the βH is registered, the client computer 1 obtains the address of the server 被 registered in the portal server Α 仁 (Fig. 8: arrow (3)) © Here, as a hypothetical situation 'may be the case where the server cannot communicate when logging in to the portal server C. In this case, the client computer 1 cannot obtain the server b from the server A. 1. The address of B2 is #B1, #B2. Moreover, in this case, the portal server c notifies the client computer 1 that communication with the feeding service § A cannot be performed (Fig. 8 : arrow (4)). After logging in to the portal server C, the operator selects the function of server B (Fig. 8: arrow (5)), then the client computer 1 is based on the server from the portal server C. The result of the notification 'determines that communication with server a cannot be performed (Fig. 11: arrow 6)). Further, since the client computer 1 has not obtained the addresses #B1 and #B2 of the servers B1 and B2, the access to the server B (B1, B2) is canceled (Fig. 11: arrow (7)). Moreover, an error message indicating that the connection has failed is output to the operator (Fig. 8: arrow (8)). That is, when logging in to the portal server C, the server α is in the shutdown state of 26 200937213, and after the server A is not restored at one time, it is judged to be rare based on the characteristics of the system, and therefore, cancels. The access to the server B (B1, B2) outputs an error message that the connection failed to the operator. When the portal server C determines that it is possible to perform communication with the server A that cannot communicate with the previous one (FIG. 8: arrow (9)), it has been restored to be able to communicate with the server A. The status of the communication is notified to the client computer 1 (Fig. 8: arrow (1〇)). When the client computer 1 receives a notification indicating that the communication with the server A can be resumed from the portal server C, the client computer 1 accesses the servo based on the obtained address A of the server A. The device A acquires the addresses #B1 and #B2 of the server bb B2 registered in the feeder A (Fig. 8: arrow (11)). Then 'If the operator selects the function of the server B (Fig. 8: arrow (^))', the client computer 1 asks whether the server a can communicate with the server B (B1, B2) (Fig. 8 : arrow (13)), if the result of the check indicating that communication with the server B1 of the processing system can be performed is returned from the server A (Fig. 8: arrow (14)), the bit of the obtained server B1 is obtained. Address #B 1, access to the server b 1 of the processing system (Fig. 8: arrow (15)). As can be seen from the above operation, in the portal server system of the second embodiment, when logging in to the portal server C, the client computer 1 acquires the bits of the servers b1 and B2 from the feeder A. Since the addresses #B1 and #B2, after logging in to the portal server C, the server B (B1) can be accessed from the client computer i even if the server 1 is turned off. In addition, it is not necessary to register the addresses B1 and #B2 of the servers B1 and B2 in the portal server C. Further, it is not necessary to add a normal check function for checking the possible state of communication with the servers B1, B2 in the server c. Fig. 9 is a flowchart showing the processing operation of the client computer 1 when the function of the server b is selected after logging in to the server C in the above-described embodiments 1 and 2. If the client computer 1 selects the function of the feeder B after logging in to the server C, the number N of the server B is calculated based on the obtained address of the server B (step S1〇1) ). In this case, in the execution state 1, the count is N = 1 ', and in the second embodiment, the count is n = 2. In addition, when logging in to the server C, if the server a cannot communicate and the address of the server B cannot be obtained, N=0. Then, the client computer 1 checks if the number N of the server B is N > 〇 (step S102). Here, if the number of servers B is N*N = 〇 (NO in step S102), the access to the server B is canceled, and the processing is terminated (step S103). If the number N of the server B is n > 〇 (YES in step S102), ❹ check whether communication is possible with the server A (step s1 〇 4), if not between the server A The communication (No in step sl4) is set to n=1 (step S1〇5), and the server n of the n=l station is accessed according to the obtained address of the server b (step 81〇6). ). For example, in the first embodiment, if communication with the server A cannot be performed (YES in step S104), the server B is accessed based on the acquired address of the server b (step S16). . In the second embodiment, 28 200937213 If communication with the server A is not possible (NO in step S104), based on the obtained bit 3 of the server Bi, „ 旳 address #B1 Accessing the servo 15 of the processing system (step S106). In contrast, 'if the communication between the freckle and the device A can be entered (YES in step 4)' (4) whether the server a can obtain the server b or not The result of the inspection is checked (step sl7). Then, (4) (step ❹ ❹) is checked to see if it is possible to carry out the goods with the clerk Bfr4» (step S109). In this case, if the result of the check with the nth station of the server β is obtained (YES in the step coffee), the H bit is taken according to the address of the obtained feeding service IS B . The n-th constructor B (step S106). If it is possible to perform the communication with the "station" of the feeder B (NO in step I), set n = n + 1 (step SUG), and repeat step S109 In addition, in the process of the imaginary process, if n > N (YES in step 1), the storage of the server B is canceled. S112). The blade picks up and ends the processing (step, for example, in the embodiment!, if communication with the feeder B 1 can be performed (YES in step S109), according to the acquired server B:: (4) access Server B (step sl6). In the second embodiment, it is possible to perform communication with the ship B1 ((4) is followed), = obtained feed service... address #B1 access processing system traffic =_). In the embodiment, if communication with the feeding is not possible, but communication with the server B2 is possible (steps are required), according to the position of the obtained feeding device 29 200937213 2 The server B2 of the standby system is accessed (step S106). In the implementation mode 2, if neither of the servers B1 and B2 can communicate (YES in step sill), the access to the server B (B1, B2) is canceled, and the processing is terminated (step S112).
