Description

  Embodiments of the present invention relate to a monitoring control device switching method, a monitoring control system, and a server.

  When updating the monitoring and control device, in order to avoid non-control and non-monitoring of the equipment to be monitored, the control and monitoring of the equipment to be monitored is provisionally established by constructing a simple monitoring and control device. It has been done. However, in order to construct a simple monitoring control device, it is necessary to register the setting regarding the central monitoring facility to be updated and to define and confirm the communication protocol with the controller on the load side. Moreover, a simple monitoring control device is often constructed on the same network as the monitoring control device. Therefore, every time the monitoring control apparatus is updated, a simple monitoring control apparatus needs to be constructed, which may require a large amount of labor.

  The monitoring data storage unit 407 stores a monitoring data table. The monitoring data table records monitoring data acquired from the monitoring control device 100. FIG. 7 is a diagram showing a specific example of the monitoring data table of the first embodiment. The monitoring data table has monitoring data records. The monitoring data record includes values of the machine site, the monitoring control device, the date and time, the controller, the equipment, and the data value. The station represents the name of the station where the monitoring control device 100 is installed. The supervisory control device represents the name of the supervisory control device 100. The date represents the date when the monitoring control device 100 receives the monitoring data. The controller represents the name of the controller 200 that has transmitted the monitoring data. An installation apparatus represents the name of the installation apparatus used as the object which acquired monitoring data. The data values represent values indicating the operating status of the equipment.

  In the example shown in FIG. 7, in the monitoring data record at the top of the monitoring data table, the value of the machine field is "machine field A", the value of the monitoring controller is "monitoring control device A", and the value of the date is "2017.11.17 11: 15: 23 ”, the value of the controller is“ A_pump — 200 ”, the value of the equipment is“ water supply pump ”, and the value of the data value is“ 1244 ”. Therefore, according to the monitoring data record at the top of the monitoring data table, the monitoring data acquired from the monitoring control device 100 is received by the monitoring control device A at the station A at 11:15:23 on November 17, 2017. I understand that. In addition, it can be seen that in the monitoring data, the controller “A_pump — 200” has acquired the data value “1244” related to the equipment “water supply pump”. The monitoring data table shown in FIG. 7 is only one specific example. Therefore, the monitoring data table may be configured in a mode different from that in FIG. 7. For example, the monitoring data table may have a different monitoring data table for each station.

  The machine location data storage unit 408 stores a machine location data table. The machine location data table records information for accessing the monitoring station and the monitoring control device 100 installed at the station and the station. FIG. 8 is a diagram showing a specific example of the device location data table of the first embodiment. The aircraft location data table has aircraft location data records. The machine location data record has values of a station, a monitoring control device, network information and an acquisition procedure. The station represents the name of the station where the monitoring control device 100 is installed. The supervisory control device represents the name of the supervisory control device 100. The network information represents information on a network for accessing the monitoring control apparatus 100. The network information may be, for example, an IP (Internet Protocol) address or a MAC (Media Access Control) address. The network information may be any information as long as it indicates the location on the network regarding the monitoring control device 100. The acquisition procedure represents a method for acquiring the monitoring data recorded in the monitoring control device 100. For the acquisition procedure, for example, an interval for acquiring monitoring data may be defined, or a communication protocol such as Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) may be defined. The airfield data record regarding the monitoring control device before updating is an aspect of the first identification information. The procedure for acquiring monitoring data from the monitoring control device before updating is an aspect of the first procedure. The airfield data record related to the monitoring control device after the update is an aspect of the second identification information. The procedure for acquiring monitoring data from the updated monitoring control device is an aspect of the second procedure.

  In the example shown in FIG. 8, the machine field data record at the top of the machine field data table has a machine field value of “machine field A”, a monitoring control device value of “monitoring control device A”, and a network information value of “192.168. The value of the acquisition procedure is “5 minutes · TCP”. Therefore, according to the station data record at the top of the station data table, it can be understood that the monitoring control device A of the station A has the IP address "192.168.1.3" as the network information. Also, it can be seen that the upper server 400 acquires monitoring data from the monitoring control apparatus A at intervals of 5 minutes using the TCP protocol. The machine location data table shown in FIG. 8 is only one specific example. Therefore, the aircraft location data table may be configured in a mode different from that of FIG. For example, the aircraft location data table may have different aircraft location data tables for each aircraft location.

  The authentication data storage unit 409 stores an authentication data table. The authentication data table stores information for accessing the upper server 400. FIG. 9 is a diagram showing a specific example of the authentication data table of the first embodiment. The authentication data table has an authentication data record. The authentication data record has the following values: login ID, password, confirmable device, authority and authentication status. The login ID is information for identifying a user who accesses the upper server 400. The password is information to be declared when the user accesses the upper server 400 using the login ID. The password may be any information as long as it is information used as an existing password such as a character string including numbers and alphabets, a combination of patterns, a line pattern, and the like. The checkable device location represents a device location that can access monitoring data when the higher-level server 400 is accessed using the login ID. The access to the monitoring data is, for example, processing of downloading the monitoring data to the terminal device 500 or checking or updating the monitoring data. The authority represents an executable authority on monitoring data. The authority can download or check the monitoring data if "read" is set. If "read / write" is set, monitoring data can be downloaded, confirmed or updated. The authentication status indicates the authentication status of the login ID of the authentication data record. The authentication status includes two statuses of authentication success and non-authentication. The authentication success represents the authenticated state. If the authentication status is authentication success, the terminal device 500 can access the monitoring data. If not authenticated, the terminal device 500 can not access the monitoring data.

  In the example shown in FIG. 9, in the authentication data record at the top of the authentication data table, the login ID value is “login_A”, the password value is “pass1234”, and the checkable machine place values are “machine floor A, machine floor B”. The authority value is “read / write”, and the authentication status value is “authentication success”. Therefore, according to the authentication data record at the top of the authentication data table, “login_A” is set as the login ID and “pass1234” as the password, and after login, the monitoring data is set to “machine field A” and “machine field B”. On the other hand, it can be seen that the "read / write" authority has been granted. Further, since the authentication status is "authentication success", it can be known that the monitoring data can be accessed at present. The authentication data table shown in FIG. 9 is only one specific example. Therefore, the authentication data table may be configured in a mode different from that of FIG. For example, the authentication data table may have a column for password expiration.

  The monitoring data acquisition unit 410 is an interface program with the monitoring control device 100. The monitoring data acquisition unit 410 acquires monitoring data from a plurality of monitoring control devices 100. The monitoring data acquisition unit 410 acquires monitoring data in the procedure associated with each monitoring control device 100. The procedure associated with each monitoring control device 100 is a procedure recorded in the machine location data table. The monitoring data acquisition unit 410 refers to the machine location data table, and acquires monitoring data based on the acquisition procedure held in the machine location data record of the monitoring control device of each machine location. Since the monitoring data acquisition unit 410 acquires monitoring data based on a predetermined procedure, the plurality of monitoring control devices 100 do not perform predetermined procedures such as definition of protocol conversion for each of the plurality of monitoring control devices 100. Monitoring data can be acquired.

  The machine location data registration unit 411 receives a machine location data record generation instruction via the input unit 403. The machine location data record generation instruction includes information related to the station, the monitoring control device, the network information, and the acquisition procedure. The machine place data registration unit 411 generates a machine place data record based on the machine place data record generation instruction. The machine place data registration unit 411 records the generated machine place data record in the machine place data table.

  The authentication data registration unit 412 receives an authentication data record generation instruction via the input unit 403. The authentication data record generation instruction includes information on a login ID, a password, a confirmable device location, and an authority. The authentication data registration unit 412 generates an authentication data record based on the authentication data record generation instruction. The authentication data registration unit 412 records the generated authentication data record in the authentication data table.

  When the authentication unit 413 receives the login ID and the password from the terminal device 500, the authentication unit 413 performs an authentication process. Specifically, the authentication unit 413 determines whether the received login ID and password are recorded in the authentication data table. When the received login ID and password are recorded in the authentication data table, the authentication unit 413 transmits information indicating successful authentication to the terminal device 500, and the authentication data record having the received login ID and password is received. Change the authentication status value to "Authentication Success". If the received login ID and password are not recorded in the authentication data table, the authentication unit 413 transmits information indicating authentication failure to the terminal device 500.

  The monitoring data transmission unit 414 transmits the monitoring data recorded in the monitoring data storage unit 407 to the terminal device 500.

  FIG. 10 is a functional block diagram showing a functional configuration of the terminal device 500 of the first embodiment.

  The authentication request unit 506 requests the upper server 400 to perform authentication. Specifically, the authentication request unit 506 receives the login ID and the password via the input unit 502. The authentication request unit 506 transmits the accepted login ID and password to the upper server 400. If the authentication is successful, the authentication request unit 506 receives, from the upper server 400, information indicating that the authentication is successful. If the authentication is not successful, the authentication request unit 506 receives, from the upper server 400, information indicating an authentication failure.
