〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a flowchart showing the operation of FIG. The artificial satellite tracking control equipment 5 tracks the artificial satellite as a target, monitors the condition of the artificial satellite by receiving a telemeter signal from the artificial satellite, and gives an appropriate command to the artificial satellite at a necessary time. Is transmitted by a command signal to control the artificial satellite. The artificial satellite tracking control equipment 5 is normally connected to the artificial satellite tracking control equipment remote control unit 1 via the signal control mechanism 4 of the computer system 20. Has been done.

The artificial satellite tracking control facility remote control unit 1 is provided in a computer system 20 that remotely controls the artificial satellite tracking control facility 5, and normally represents the operating state of the equipment in the facility from the artificial satellite tracking control facility 5. The signal is converted into a response / state information signal 3 which is a logic signal in the computer system 20 via the signal conversion unit 4 in the computer system 20 and output to the artificial satellite tracking control facility remote control unit 1 described above.

The artificial satellite tracking and control facility 5 is configured such that once the activation signal is applied, the time signal is given at a predetermined time interval for a predetermined time, that is, after the target satellite is launched, the predetermined control work is performed. Generate until the time when it is expected to end.

The artificial satellite tracking and control equipment 5 is autonomous without a control signal from the outside after a specific time has elapsed after the activation signal was added in synchronization with the time signal while the time signal was being generated. A certain operation is performed on the computer system 20 as a status information signal.
The signal corresponding to the control information signal 2 transmitted from the artificial satellite tracking control facility remote control unit 1 in the computer system 20 is received from the signal conversion unit 4 and designated based on this signal. When the operation described above is performed and this operation ends, a response signal indicating the state where this operation is performed is sent to the computer system 20 described above.

Further, the artificial satellite tracking and control equipment 5 described above may perform other operations in association with this autonomous or operation in accordance with the control information signal, and status information indicating the status of such associated operations. To the signal conversion unit 4 described above.

The artificial satellite tracking control equipment remote control unit 1 provided in the computer system 20 is a control information signal for remotely controlling the operation of each device in the artificial satellite tracking control equipment 5 previously set in the built-in program. 2 is transmitted in response to the response / state information signal 3 which is the response signal or the state information signal described above.

Normally, the above-mentioned control information signal 2 is sent from the artificial satellite tracking control facility remote control unit 1 to the signal conversion unit 4, and
The above-mentioned response signal and status information signal from the artificial satellite tracking control facility 5 are converted into a response / status information signal 3 which is a logical signal in the computer system 20 by the signal converting unit 4, and the artificial satellite tracking control facility remote control unit. Input to 1.

Since the control information signal 2 is a logical signal in the computer system 20, the signal conversion unit 4 controls an appropriate device in the artificial satellite tracking and control facility 5 which is predetermined corresponding to the control information signal 2. A signal, for example, a contact control signal of a relay or the like, an electric signal such as a voltage control signal, or the like is converted and sent to the artificial satellite tracking and control facility 5.

In FIG. 1, a signal conversion unit 4 for the control information signal 2 and the response / status information signal 3 of the artificial satellite tracking control facility remote control unit 1
Is shown by a dotted line. In this figure, the control information signal 2 and the response / status information signal 3 which are the inputs and outputs of the artificial satellite tracking control facility remote control unit 1 are the response signals of the satellite tracking control facility simulator 6, respectively. The state in which the generator 7 and the related signal generator 8 are connected is shown.

As described above, in FIG. 1, the artificial satellite tracking control facility remote control unit 1 is connected to the artificial satellite tracking control facility simulator 6, and the artificial satellite tracking control facility remote control unit 1 is an artificial satellite. It shows a state in which the operation of the tracking control facility 5 is being simulated.

Time activation signal from remote control unit 1 for satellite tracking and control equipment
When 14 is sent to the time management means 10 of the artificial satellite tracking and control equipment simulator 6, the time management means 10 starts generating a time signal at a predetermined time interval (step 100). This time signal is added to the state signal generating means 9, and the state signal generating means 9 searches the state signal reference table for the state corresponding to this added time (step 101).

Here, the state signal is a signal corresponding to a state of operation in which the device in the artificial satellite tracking and control facility 5 autonomously starts when the above-mentioned time signal reaches a specific value.

If the status signal corresponding to the generated time is in the status signal reference table 13, the corresponding status signal is generated by the status signal generation means 9
Are extracted and generated by and are sent to the related signal generating means 8 (step 102).

The related signal generation means 8 sends the signal output from the status signal generation means 9 as it is to the artificial satellite tracking and control facility remote control section 1 as the response / status information signal 3 (step).
At the same time, the related signal reference table 12 is searched for whether or not there is a status signal generated in association with this status signal (step 104).

It should be noted that the related signal reference table 12 is related in advance to the above-mentioned status signals when another status related to this status signal occurs in the equipment in the artificial satellite tracking and control facility 5, and after the response signal generation described later. If there is a state that occurs as a result of this, the above-mentioned associated state signal corresponding to these state signals or response signals is stored.

Furthermore, when the status signal generated in relation to these status signals occurs after a specific waiting time has elapsed since the response signal or the status signal was generated prior to this status signal, this waiting time also corresponds to the status signal described above. And remember it.

If there is a related status signal, the related signal generating means 8 extracts and generates the related status signal (steps 109 and 11).
0).

If the related status signal does not require a specific waiting time, the response / status information signal 3 is output.
When the related status signal requires a waiting time, this required waiting time is extracted from the related signal reference table 12 and sent to the second waiting time processing means 16 as a waiting time setting signal. When the activation signal from the waiting time processing means 16 is received, the related status signal described above is output as the response / status information signal 3 (steps 111, 112 and 103).

The second waiting time processing means 16 described above is synchronized with the time signal generated by the time management means 10, and when the waiting time setting signal specifying the waiting time is received, the start signal is sent when the specified time has elapsed. Send out.

Further, the artificial satellite tracking control facility remote control unit 1 generates artificial hygiene for the artificial satellite tracking control facility 5 at an appropriate timing after generating the time activation signal 14 based on a preset internal program. Alternatively, the control information signal 2 corresponding to a series of operations to be performed on the rocket is generated and sent to the response signal generating means 7.

The response signal generator 7 searches the response signal reference table 11 for a response signal corresponding to the input control information signal 3 and extracts and generates a response signal corresponding to the control information signal 2 (steps 113 and 113). 114).

The response signal is a signal indicating that the operation corresponding to the control information signal is performed based on the control information signal,
For example, in response to a control information signal related to turning on a power switch of a specific device in the artificial satellite tracking and control facility 5, a signal indicating that the power switch is turned on is a response signal.

The operation based on the above-mentioned control information signal is received in the artificial satellite tracking control equipment 5 or the artificial satellite to be controlled through this equipment or the equipment in the rocket for launching this artificial satellite. There are things that are performed with a time delay after the start.

For the response signal corresponding to such an operation, in addition to the response signal corresponding to the control information signal, the amount of time delay is stored in advance in the response signal reference table 11 as the waiting time corresponding to the control information signal. deep.

The response signal generating means 7 detects the amount of time delay of the extracted response signal, that is, whether or not the waiting time is required, and if the waiting time is required, the waiting time setting signal for requesting the required waiting time. Is sent to the first waiting time processing means 15, and if not necessary, a response signal is output to the related signal generating means 8 (step 115).

The first waiting time processing means 15 is synchronized with the time signal sent by the time management means 10, and when the waiting time setting signal is received, the response signal requested when the time designated by this waiting time setting signal elapses. An activation signal for activating is sent to the response signal generating means 7.

The response signal generating means 7 receiving this activation signal sends the corresponding response signal to the related signal generating means 8 (step 11).
6).

The related signal generating means 8 outputs this response signal as the response / status signal 3 to the artificial satellite tracking control facility remote control unit 1 (step 103).

Further, the related signal generating means 8 has a related signal reference table 12
Is checked to see if there is a status signal that is associated with the response signal (step 104).

After that, the operations from step 109 to step 112 already described are performed.
