Description

  The present invention relates to a safety confirmation system that transmits text information or voice information and receives a response from a customer in order to confirm the safety of a customer registered in the system when an emergency such as a disaster occurs. The present invention relates to means for determining which safety confirmation server an operator should access when the safety confirmation servers are distributed in a region and means for keeping system information used in common in each safety confirmation server in the latest state.

  If there is only one safety confirmation server in the safety confirmation system, the safety confirmation system may become unusable if the safety confirmation server is deactivated due to disaster damage or the like.

  Therefore, a method has been proposed in which a plurality of safety confirmation servers are distributed in a region, and a safety confirmation server that has been suspended due to disaster damage or the like is backed up by a safety confirmation server located in another region (for example, (See Patent Document 1).

Japanese Patent Laid-Open No. 8-316955 (pages 2 and 3 in FIG. 1)

  In the above-described conventional method of distributing a plurality of safety confirmation servers in a distributed region, a safety confirmation server that backs up a safety confirmation server that has been suspended due to disaster damage or the like is determined in advance. At a minimum, the operator must operate the system while being aware of the existence of a plurality of safety confirmation servers and the system configuration of their arrangement.

  In addition, when the safety confirmation server to be backed up becomes difficult to operate, there is a problem that the safety confirmation information cannot be accessed even though there are other live safety confirmation servers.

  Furthermore, if system information used in common in a plurality of safety confirmation servers is not synchronized, there is a problem that old safety confirmation information is taken in and believed.

  SUMMARY OF THE INVENTION An object of the present invention is to enable an operator to operate from an information input terminal without being aware of the existence of a plurality of safety confirmation servers and their connection system in a safety confirmation system in which a plurality of safety confirmation servers are distributed in a region. Another object of the present invention is to provide a safety confirmation system having means for keeping system information synchronized with each other and keeping them up to date.

  In order to solve the above problems, the present invention provides an information input terminal for an operator to input outgoing information and system information, and an outgoing information and system information from an information input terminal by an operator distributed in a geographically distant area. Safety confirmation that consists of a plurality of safety confirmation servers that receive and process outgoing information and send to customers registered in the system, and a response input terminal that receives outgoing information from the safety confirmation server and sends responses from customers to the safety confirmation server In the system, each safety confirmation server includes a safety confirmation database including a transmission information file and a system information file, a safety confirmation server list, and a system information flag file indicating whether the system information is valid / invalid / corrected. Information input terminal sends safety confirmation database including safety confirmation server list and outgoing At the time of report input / system information correction, based on the list of safety confirmation servers, the system information is in the latest state, and a safety confirmation server that is in operation is searched. System information correction operation processing means for inputting system information, rewriting the system information flag at the time of system information correction, and invalidating the system information of the safety confirmation server that is not subject to system information correction among the searched safety confirmation servers; We propose a safety confirmation system with

  Each safety confirmation server periodically searches for a safety confirmation server that is subject to system information correction based on the safety confirmation server list when system information is invalidated, and detects the end of system information correction. The system information synchronization processing means for obtaining the latest system information from the safety confirmation server and effectively changing its own system information flag is provided.

  According to the present invention, in a safety confirmation system in which a plurality of safety confirmation servers are distributed in a region, an operator inputs outgoing information from an information input terminal without being aware of the existence of the plurality of safety confirmation servers and their connection system. Information can be modified. In addition, system information can be synchronized with each other and kept up to date.

  Next, with reference to FIGS. 1-9, the Example of the safety confirmation system by this invention is described.

  FIG. 1 is a block diagram showing the relationship among the information input terminal A, the safety confirmation server B, and the response input terminal C of the safety confirmation system according to the present invention.

  The safety confirmation system according to this embodiment includes an information input terminal A, a safety confirmation server B, and a response input terminal C. There are a plurality of safety confirmation servers B, and each safety confirmation server B is distributed in geographically separated areas.

  A network line connects between the information input terminal A and the safety confirmation server and between the safety confirmation servers distributed in the region. The safety confirmation server and the response input terminal C are connected by a telephone line and a network line.

  The information input terminal A is a terminal for an operator to input transmission information and system information.

  The safety confirmation server B receives the transmission information and system information from the information input terminal A by the operator, processes the transmission information, and transmits it to the response input terminal C using various transmission means. The response input terminal C receives the transmission information from the safety confirmation server B, and transmits a response from the customer registered in the system to the safety confirmation server B.

  FIG. 2 is a block diagram showing the internal configuration of the information input terminal A and the safety confirmation server B of the safety confirmation system according to the present invention.

  In the information input terminal A, the safety confirmation database 7 stores a safety confirmation server list 8 in a file format.

  In the safety confirmation server B, the safety confirmation database 1 stores the transmission information 2 and the system information 3 in the relational database format, and stores the system information flag 5 and the safety confirmation server list 6 in the file format.

  FIG. 3 is a diagram illustrating an example of parameters used in the safety confirmation list 8, the processing result (safety confirmation server selection process) 14, and the processing result (system information exclusion availability determination process) 15.

  The system information 3 stores customer information registered in the system and information shared by all safety confirmation servers B in the safety confirmation system. The safety confirmation server list 6 on the safety confirmation server B and the safety confirmation server list 7 on the information input terminal A include the network address 201 of the safety confirmation server B as shown in 101 of FIG. There are items of network addresses 201 corresponding to the total number of confirmation servers B.

  The system information flag 5 has three states: valid, invalid, and corrected. Valid is the latest system information 3 on the safety confirmation server B, and invalid is the latest system information 3 on the safety confirmation server B. This means that the information input terminal A is correcting the system information 3 on the safety confirmation server B.

  The transmission input process 12 and the system information correction operation process 13 of the information input terminal A are updated with reference to the safety confirmation database 1 on the safety confirmation server B, and the safety confirmation server selection process 14 and the system information exclusive of the information input terminal A are updated. The availability acquisition process 15 is called, and the transmission input process and the system information correction operation process are performed while communicating with the same name process of the safety confirmation server B.

  The safety confirmation server selection process 14 and the system information exclusion availability acquisition process 15 of the information input terminal A perform the safety confirmation server selection while referring to the safety confirmation database 1 of the safety confirmation server B and the safety confirmation database 8 on the information input terminal A. Processing and system information exclusion availability acquisition processing.

  The transmission input process 12 and the system information correction operation process 13 of the safety confirmation server B receive the communication from the same name process of the information input terminal A and update it with reference to the safety confirmation database 1 on the safety confirmation server B. Outgoing input processing and system information correction operation processing are performed.

  The system information synchronization process 11 of the safety confirmation server B communicates with the process of the same name of the other safety confirmation server B, and performs the system information synchronization process while updating with reference to the safety confirmation database 1 on the safety confirmation server B.

  Next, three processes of a call input operation process 12, a system information correction operation process 13, and a system information synchronization process 11, a safety confirmation server selection process 14 called from the call input operation process 12 or the system information correction operation process 13, and system information Two processes of the exclusion permission / inhibition acquisition process 15 will be described.

  FIG. 4 is a flowchart showing the processing procedure of the outgoing call input operation processing 12.

  The information input terminal A first executes a safety confirmation server selection process (see FIG. 7 described later), and acquires a processing result (S101).

  The processing result of the safety confirmation server selection process is configured by the network address 202 of the safety confirmation server B as shown by 102 in FIG. 3, and the safety confirmation server B is equal to the number of safety confirmation servers B included in the processing result. Of the network address 202 exists. If the information on at least one safety confirmation server B is not included in the list of processing results, the processing is stopped (S102).

  If at least one safety confirmation server B information is included in the list of processing results, one of the top items in the list is selected and the transmission input information input by the operator is transmitted to the selected safety confirmation server B. (S103).

  Upon receiving the transmission input information from the information input terminal A, the selected safety confirmation server B stores the received information in the transmission information of the safety confirmation database on its own server (S104).

  The safety confirmation server B transmits a response to the input terminal based on the transmission information. Since this process is the same as the case where there is only one conventional safety confirmation server B, the description of the process content is omitted.

  FIG. 5 and FIG. 6 are flowcharts showing the processing procedure of the system information correction operation processing 13.

  First, the information input terminal A executes a system information exclusion permission acquisition process (FIG. 8) and acquires a processing result in order to determine whether or not the system information can be exclusively modified (S201).

  As shown in 103 of FIG. 3, either “success” or “failure” is stored in the processing result 203 in the processing result, and therefore the processing is canceled in the case of failure (S202).

  If successful, a safety confirmation server selection process (FIG. 7) is executed next, and a process result is acquired (S203).

  If no information of the safety confirmation server B is included in the list of processing results, the processing is stopped (S204).

  If the information of at least one safety confirmation server B is included in the list of processing results, the system status flags on all the safety confirmation servers B stored in the processing results are changed (S205).

  Specifically, one safety confirmation server B in the first row is selected from the list, and the system status flag of the selected safety confirmation server B is changed from valid to being modified. For the safety confirmation server B other than the first line in the list, the system status flag is changed from valid to invalid.

  In S205, the system information is acquired from the safety confirmation server B changed during the correction of the system status flag (S301), and the operator can correct the system information.

  When the correction of the system information by the operator is completed, the correction information of the system information is transmitted to the safety confirmation server B that acquired the system information in S301 (S302).

  When the safety confirmation server B receives the correction information, it stores the received information in the system information of the safety confirmation database on its own server (S303).

  The safety confirmation server B also changes the system information flag of its own server from being modified to valid (S304).

  FIG. 7 is a flowchart showing the procedure of the safety confirmation server selection process 14 called from the call input operation process 12 or the system information correction operation process 13. The information input terminal A first acquires the first item of the safety confirmation server list 8 existing in the safety confirmation database 7 of its own terminal (S401).

  The existence of the safety confirmation server B is monitored by monitoring the existence of the network address of the safety confirmation server B included in the acquired item (S402).

  If the safety confirmation server B is not alive (S403), the process proceeds to S408.

  If it exists, the system information flag of the safety confirmation server B of the acquired item is referred to (S404), and it is checked whether the system information flag is valid (S405).

  If not valid, the process proceeds to S408.

  If it is valid, the information of the safety confirmation server B of the acquired item is added as one item of the processing result (S408).

  It is checked whether there are any remaining items in the safety confirmation server list 8. If there are remaining items (S408), the next item in the safety confirmation server list 8 is acquired and the process proceeds to S402 (S407).

  If there are no remaining items, this process ends.

  FIG. 8 is a flowchart showing the processing procedure of the system information exclusion permission acquisition processing 15.

  The system information exclusion permission acquisition process 15 is called from the system information correction operation process 13. The information input terminal A first acquires the first item of the safety confirmation server list 8 existing in the safety confirmation database 7 of its own terminal (S501), and monitors the existence of the network address of the safety confirmation server B included in the acquired item. Then, the presence / absence of the safety confirmation server B is checked (S502).

  If the safety confirmation server B is not alive (S503), the processing result is regarded as abnormal (S506), and this processing is terminated.

  If the safety confirmation server B is alive, the current transmission state is checked with reference to the transmission information 2 existing in the safety confirmation database 1 of the acquired safety confirmation server B (S504).

  If the transmission is in progress or the response is being accepted (S505), the processing result is regarded as abnormal (S506), and this processing is terminated.

  If there is no outgoing call and no response is received (S505), it is checked whether there are any remaining items in the safety confirmation server list 6. If there are remaining items (S508), the next in the safety confirmation server list 6 Are acquired, and the process proceeds to S502 (S507).

  If there are no remaining items, the processing result is regarded as normal (S509), and this processing is terminated.

  FIG. 9 is a flowchart showing a processing procedure of the system information synchronization processing 11. The safety confirmation server B first checks whether it is valid with reference to the system information flag 5 of its own server (S601).

  If it is valid, the process proceeds to S601 again after a predetermined time has elapsed. If it is not valid, the first item of the safety confirmation server list 6 existing in the safety confirmation database 1 of the own server is acquired (S602).

  The existence of the safety confirmation server B that is alive is checked by monitoring the existence of the network address of the safety confirmation server B included in the acquired item (S603).

  If the safety confirmation server B is not alive (S604), the process proceeds to S610.

  If it is alive, the system information flag 5 of the safety confirmation server B of the acquired item is referred to (S605).

  If the system information 5 is valid (S606), the system information 5 is acquired from the safety confirmation server B of the acquired item and the system information 5 of the own server is updated (S607), and the system status flag of the own server is enabled. Change (S608), and proceed to S601.

  If the system information 5 is not valid, it is checked whether or not there are remaining items in the safety confirmation server list 6. If there are remaining items (S610), the next item in the safety confirmation server list 6 is acquired, The process proceeds to S603 (S609).

  If there are no remaining items, the process proceeds to S601.

  In the present invention, since the information input terminal A communicates while automatically switching between a plurality of safety confirmation servers B, and the system information is automatically synchronized between the safety confirmation servers B, there are a plurality of safety confirmation servers B. Thus, even if the areas are distributed, the operator can perform the call input operation and the system information correction operation without being aware of it, and the system information can be synchronized with each other to be always kept up-to-date.
