Each tr military aircraft has a request mediation gr c'4,: 09, :: 1, and the request section has a request target Ξ «: 05, :: 0, :: 2 Automatic operation control § -: ΰ6 is a schedule mail: The communication line 125 is inserted from C'T, and the schedule information is inserted. Make and receive requests. Schedule 21 107 Communication line: Can be set from beta console 123 via 24.

The control request issued by the automatic operation e-control K 106 reaches the request relay ffi i from the request relay unit 104 via the communication line 1, and is received by the power source control device control 4 via the communication line 113. The power control device S control unit I i 4 interprets the received request and issues a power control device S120 control command via the signal line 116.

Next, the configuration of the automatic operation G control unit will be described with reference to §!

The automatic operation control unit 106 reads the schedule information from the schedule file 107 and analyzes the start / stop schedule. The schedule analysis unit 203 issues a start request K fixed request based on the analysis result. The setting unit 206, the stop time setting 20: processing the setting of the timer started at the stop i time, etc., and the “stop time setting 2: 201”, according to the start of the timer set in 201 It consists of a stop control unit 205 that performs a prize. Startup time set 35206 by Ri created Okoshi勳request message and I request message stops I was made Li ^{/ (E} stop control unit 205 is transmitted via the communication line 108 together.

Next, the configuration of the power supply control device will be described using FIG.

The power control collision device i 20 has a power supply line T, US.::9, and I computers are connected to the power supply line i to supply power to the power supply line. To start and stop; 2) Control the power of the computer. Power supply switch circuit 30 :, 202.303 is a circuit for opening and stopping power supply ^^ Switch connection? =, ^ 30 and controlled by control information sent via ffi lines 3 04. 305 and 306.

The command for turning on and off the power is received via a signal line 116 and analyzed by the second interface nice part 313. If a stop request is made, the command is sent via a communication line 314. Power supply control is passed to 81309, and if there is a start request, power supply start control via communication line 315 Passed to 2. The stop request is passed in the form of “Specify after the specified time has passed and the power supply line is cut off?”, So the power stop control ffi 309 describes these contents * Stop A request section 310 is provided. Similarly, in order to store the power start request, the power start control unit 3 is provided with a start request record «part 3: 2: _t E 愫時時時時開始 or start At time j, the power is shut off when the power reaches two times.
