  5 to 7 are flowcharts showing the flow of control monitoring according to an embodiment of the present invention. With reference to FIGS. 1 to 7, control and monitoring of the ground test of the artificial satellite 20 according to one embodiment of the present invention will be described.

  When a line (line via the Internet network 15) is connected to the ground test equipment server 24 (step S1 in FIG. 5), the contents stored in the ground test equipment server database 241 and the control surveillance terminal are connected. When the database contents are different from each other, the latest database is copied to the ground test equipment server internal database 241 and the ground test equipment server internal database 241 and the control monitoring terminal are always copied. The version of the internal database 251 is matched (step S2 in FIG. 5).

  Further, the ground test apparatus server 24 checks the (connection, operation) state of the target test apparatus before starting the ground test of the artificial satellite 20, and notifies the control monitoring terminal 25 of the check result (step S3 in FIG. 5). ).

  A plurality of operators (hereinafter referred to as “users”) who operate the terminals 27a to 27c to control and monitor the ground test of the artificial satellite 20 select the control command B and the monitoring command A registered in the database. Control instruction and monitoring instruction procedure editor / execution modules 271a to 271c are registered to control monitoring sequences (for example, “control c”, “monitor b”, “control a”, “monitor b”, “instruction a”, etc.) Step).

  Further, the control instruction and monitoring instruction procedure editor / execution modules 271a to 271c have function functions such as a repeat instruction, a branch instruction, an operation instruction, a call instruction, an input / output instruction, a collation instruction, etc., and the user can perform arbitrary control monitoring.

  Executing one item of the control command B on the terminals 27a to 27c is equivalent to executing one control on the ground test apparatus computer 22, and one item of the monitoring command A on the terminals 27a to 27c. Executing is equivalent to executing one monitoring on the ground test apparatus computer 22.

  In the present embodiment, the control monitoring sequence created by the control command and monitoring command procedure editor / execution modules 271a to 271c (a combination of the control command B and the monitoring command A in a user arbitrary sequence [test procedure]) is used. By executing automatically, control / monitoring automation (automation of ground test of the artificial satellite 20) can be realized. The control monitoring sequence execution state can be monitored by other users.

  The control monitoring sequence checks the (connection, operation) status with the target test device and the consistency with the database before starting execution (step S19 in FIG. 6), and an error [the test device for control monitoring is connected. If it is not (not operating), inconsistent with database registration contents, etc.], a warning notification to that effect is sent to the user and a request to delete or skip the corresponding sentence is executed (steps S20 to S22 in FIG. 6). .

  In this embodiment, the user executes the control monitoring sequence created by the above procedure (exclusion of manual input operation), and the ground test apparatus server 24 and the control monitoring terminal 25 determine control and monitoring (discrimination of illegal instructions). ) And the monitoring of the control monitoring sequence and execution state by other users, the risk of misoperation etc. is avoided.

  The user selects an arbitrary control command B or monitoring command A stored in the control monitoring terminal database 251 from the terminals 27a to 27c or creates a control monitoring sequence. The command selected by the user is transferred to the ground test equipment server 24 through the control monitoring terminal 25 and the Internet 15 by executing on the terminals 27a to 27c or executing a control monitoring sequence. The ground test apparatus server 24 reads the transmitted command and transfers it to the appropriate test apparatus computer 22 and test apparatus 21 (steps S23 to S29 in FIG. 6, step S30 in FIG. 7).

  After successfully executing the requested command, the test apparatus 21 notifies the execution result to the terminals 27a to 27c through the ground test apparatus server 24, the Internet network 15, and the control monitoring terminal 25 (steps S31 to S35 in FIG. 7). Each terminal 27a to 27c displays the notified control result and notification content (steps S31 to S38 in FIG. 7).

  In addition, the ground test apparatus server 24 recognizes and discriminates the control sent from a plurality of users, and registers in the database whether the control signal transmitted from one user affects the control and monitoring of other users. The information is compared and discriminated (step S26 in FIG. 6), and if it is affected, the control signal is held (unexecuted) to confirm the affected user (steps S27 and S28 in FIG. 6). The ground test apparatus server 24 resumes the held control signal upon receipt of the continuation notice from the user (step S29 in FIG. 6, steps S30 to S33 in FIG. 7).

  In the present embodiment, the above processing is repeated (steps S18 to S29 in FIG. 6 and steps S30 to S39 in FIG. 7), thereby performing real-time control of the ground test of the artificial satellite 20 by a plurality of users.

Status data of the test apparatus 21 is distributed to the ground test apparatus server 24 via the ground test apparatus LAN 23 at regular intervals (steps S5 to S10 in FIG. 5).

  When the ground test equipment server 24 receives the acquisition data from the artificial satellite 20 and the status data of the ground test equipment 21 from each ground test equipment computer 22, the data is transferred to the control monitoring terminal 25 via the Internet 15. (FIG. 5, step S11).

  The control monitoring terminal 25 transfers the data transferred from the ground test apparatus server 24 to the plurality of terminals 27a to 27c requesting the data via the user office LAN 26 (step S12 in FIG. 5). Each of the terminals 27a to 27c displays the data transferred from the control monitoring terminal 25 (steps S13 to S15 in FIG. 5).

  As described above, in this embodiment, the number of test data communications through the Internet network 15 is reduced, and TCP / IP (Transmission Control Protocol / Internet Protocol) processing of the ground test server 24 is reduced. By limiting the test data transmitted from the control monitoring terminal 25 to the terminals 27a to 27c (sending only necessary data for each user, compressing and transmitting the data), real-time performance is achieved.

  In the present embodiment, the above-described processing is repeatedly performed (steps S4 to S16 in FIG. 5), thereby performing real-time monitoring of the ground test of the artificial satellite 20 and real-time data evaluation. Further, in this embodiment, the ground test of the artificial satellite 20 is monitored by a large number of users, thereby avoiding dangers such as a control sequence and improving reliability.

  A user who has found an abnormality issues an abnormality detection notification from the terminals 27a to 27c to the control monitoring terminal 25 via the user office LAN 26. Upon receipt of the abnormality discovery notification, the control monitoring terminal 25 transfers the abnormality discovery notification to each of the terminals 27a to 27c, and notifies all the users who are monitoring the test that the abnormality discovery notification has been issued and the control has been stopped ( FIG. 6 step S23). At the same time, the control / monitoring terminal 25 transfers an abnormality detection notification to the ground test apparatus server 24.

  When the ground test equipment server 24 receives the abnormality discovery notification from the control monitoring terminal 25 (step S24 in FIG. 6), it notifies all the ground test equipment computers 22 that the abnormality discovery notice has been issued via the ground test equipment LAN 23. At the same time, the control is stopped (step S25 in FIG. 6).

  When all the ground test apparatus computers 22 receive the abnormality detection notification from the ground test apparatus server 24, the control under execution is stopped. Each ground test apparatus 21, each ground test apparatus computer 22, and the ground test apparatus server 24 maintain the current setting and status until the abnormality detection notification cancellation is issued by the user.

  Each ground test device 21, each ground test device computer 22, and ground test device server 24 finds an abnormality in the same processing flow as when an abnormality detection notification is issued from the user when an abnormality detection notification is issued by the user. Transmits notification cancellation and resumes control.

  In the present embodiment, control, monitoring, data evaluation, and response at the time of abnormality detection of the ground test of the artificial satellite 20 can be performed in real time via the Internet network 15. The same effect as when the ground test of the artificial satellite 20 is carried out by visiting the ground test facility can be obtained.
