PURPOSE:To surely transmit information by providing a voltage detecting part at a driving power source circuit from the base material inside a flying object, and detecting a command signal together with a driving voltage. CONSTITUTION:By using a starting power source circuit from the base material to a flying object 10, a voltage signal detecting part 13 is provided at the power source circuit in the flying object 10. A signal discriminating part 32 inputs a detecting signal (h) detected in the voltage signal detecting part 11, further, inputs an internal voltage signal F of the flying object from a driven device 3, and discriminates an information command signal (i) from the detecting signal (h). There, a driving voltage or an information command signal (i) continuously after the driving voltage are sent from the base material to the flying object 10, and by using the voltage signal detecting part 11, the information is transmitted to the flying object. Thus, since the power source line is used for the information transmitting line, a circuit impedance is decreased, noise resistance and external disturbance resistance are increased.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a starting power circuit for an actuating device in the flying object before it is separated from the mother body for an object that is to be separated from the mother body and is about to fly. This relates to a method of transmitting operation mode information of a flying object from a parent body to a flying object through a flying object that is fired or separated from a parent body.
In order to activate the device inside the flying object before it is released, a starting power supply voltage is applied from the parent body to the flying object, and the power supply circuit 1 inside the flying object is connected in a circuit such as a battery. There is.

For example, FIG. 12 is a diagram showing an example of a conventional power starting circuit for a flying object. In the figure, (1) is the main remote control unit, (2) is the battery, (3) is the driven device, (4 is the relay, and (5) is the interlocking unit θ, which is the switch unit connected to the relay (4). depending on the operating state of relay (4).

The terminals indicated by a and b are connected by the switch part (5) K, and are brought into a disconnected state. (6) is relay (2),
(71 indicates a switch part connected to the relay (6) at the connecting part f, and depending on the operating state of the relay (6), the terminals C, a
The IE is connected by the switch unit ( ) 1, and the unconnected JIIK is established. tai indicates a plug that connects the power line between the mother body side and the flying object side shown by the cod, and (9) indicates the joint when the flying object is separated from the mother body.

Next, the operation will be explained. In order to operate the driven device (31) in the flying object u using the remote control unit shown in (1), the signal g to drive the relay (4) is first applied to the relay (4) K. Relay (4) receives the drive signal and connects terminals a and b of switch part (+51) through connection part e, and connects the battery (21) inside the flying object to the driven device (31). At the same time, a voltage is applied to the relay (6), and the switch part (71 connects terminals c and 4 through the connection part t). In this state, the drive signal g from the remote control part (1) is applied. Even if the relay (4) appears inactive and the switch unit (ω) disconnects the terminals a and b, the battery (2) is connected to the driven device (3) via the terminals C and a. ) is connected to the driven device (31) within the flying object.

Therefore, the flying body a is separated from the parent body.

Even if the plug (81) is separated at the joint (91), the device inside the flying body will continue to operate.

The above is the conventional method for driving power to a flying object.

By the way, there are cases where it is desired to set the operating mode of the device inside the flying object before separating it from the parent body.

For example, the example shown in FIG. 12 is a case where it is desired to change the operation mode depending on local conditions such as weather conditions, day and night, and cloud cover.

[Problem to be solved by the invention]

The conventional power line between the mother body and the flying object is.

With the configuration as described above, in order to transmit separate information signals such as operation mode, it is necessary to increase the number of lines or to use another means of transmitting, such as using radio waves.

However, increasing the number of lines requires an increase in the number of pins on the connector, and also requires additional and refurbished wiring on the motherboard side. Furthermore, when radio waves are used, problems may occur such as information not being transmitted or incorrect information being transmitted due to jamming radio waves.

This invention was made in order to solve the above-mentioned problems, and provides a method that enables transmission of power drive commands and operation mode command information of the flying body's internal device using only one line between the mother's body and the flying body. The purpose is to.

[Means for solving problems]

On the other hand, an information command signal is sent from the parent body to the flying object or after the driving voltage, and the voltage detection section is used to transmit information to the flying object.

[Effect]

The information transmission method of the present invention uses a power supply line as the line for information transmission, so the impedance of each circuit is low, so it is resistant to noise, and the voltage level can be reduced by disturbances such as 2GV lines can be used if the mother body is an aircraft or ship. Strong against

Another method of information transmission is the 4th method as shown in Figure 6.
The voltage level discriminator c23 shown in the figure is configured as a pulse array discriminator @, as shown in FIG.

The configuration of the detection signal is the command signal 8 after the external drive voltage vOO.
By transmitting the array 1.82.85 by omitting the part 83 as shown by the broken line, the command signal s1. s2 can be obtained, and in the 6!4 pulse arrangement discriminator, sl, s2

In the above embodiments, the case where the application is applied to a flying object was explained, but the application is applied to an object traveling on a trajectory.

For objects running on the sea or under the sea, etc., which are separated after receiving a drive voltage signal from the parent body and are about to run or fly.
Needless to say, it is effective if the operation mode information is provided together with the drive signal.
