DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the non-arming device according to the present invention and a commander used in the device will be described below with reference to the drawings.

FIG. 1 shows the base of the non-arming device of the present invention.
It is a 1st reference example which shows the structure used as a book. In this figure, the non-arming device is provided with an antenna 20, a coupler 12, a receiver 1, a discriminator 3, and a comparator 13, as shown by a dotted frame, and these are land mines and guided bombs. It is mounted on the explosive device together with the fuse 4 of the explosive device.

On the other hand, the non-arming device commander 2 is placed at a position distant from the non-arming device and is changed (for example, turned on or off) by a code representing a command for non-arming. A radio wave 22 obtained by modulating a transmission signal with a signal is emitted from the antenna 21.

In the structure of the first reference example , when the fuse 4 of the explosive device is in the arming state, the non-arming device is in an operable state, and the receiver 1 matches the transmission frequency of the command device 2. Received at the specified frequency. Then, the output of the commander 2 is radiated from the antenna 21 as a radio wave 22, and this is applied to the receiver 1 through the antenna 20 and the coupler 12 of the non-arming device. The coupler 12 is for matching the impedance between the antenna 20 and the receiver 1. The output of the receiver 1 is added to the discriminator 3 and discriminated whether it is the radio wave 22 of the command device 2. That is, it is identified whether or not the specific identification signal added on the commander side is detected. When it is determined that the signal is the radio wave of the commander 2, the output signal of the discriminator 3 is sent to the comparator 13, and the comparator 13 compares it with a code for putting the fuze 4 in the non-arming state. The non-arming signal is given to.

In the case of the above-mentioned first reference example, the fuze is established wirelessly.
From the arming state to the non-arming state
Yes, but non-arming device does not have transmission function
Therefore, communicate with the commander for the non-arming device.
It is not possible to specify the state of the non-arming device as described above.

A computer 5, a comparator 13, and a transmitter 6 are provided, and these are a fuze 4 of an explosive device such as a guided bomb and other devices (devices for target tracking, various devices for state detection, etc.). It is mounted on the explosive device together with 15. Here, the switch 14 inserted between the coupler 12 and the receiver 1 is for switching transmission and reception. Further, the computer 5 accumulates and processes information about the fuze 4 and other devices 15 in accordance with many commands sent from the command device 2, and can communicate with the command device 2 via the transmitter 6.

In the structure of the first embodiment, when the fuse 4 of the explosive device is in the arming state, the non-arming device is in an operable state, and the switch 14 connects the coupler 12 and the receiver 1. Thus, the receiver 1 is in a receiving state at a specific frequency that matches the transmission frequency of the command unit 2. Then, when a command for non-arming is issued from the command device 2, a radio wave 22 is radiated from the antenna 21, and the receiver 1 is operated by the same operation as in the case of the first reference example described above . The output is added to the discriminator 3 to discriminate whether it is the radio wave 22 of the command device 2, and when it is found that it is the radio wave of the command device 2, the output signal of the discriminator 3 is sent to the comparator 13 via the computer 5. When the comparator 13 determines that the code is a code for putting the fuze 4 in the non-arming state, the fuze 4 is given a non-arming signal. When a command for communication is issued from the command device 2, the computer 5 receiving the output of the discriminator 3 detects that the command device 2 has issued a command for communication, and the fuze 4 And the stored / processed information about the other device 15 is transmitted to the command device 2 as a radio wave through the path of the transmitter 6, the switch 14, the coupler 12 and the antenna 20.

The identification signal generator 7 outputs an identification signal of a specific frequency (for example, a specific low frequency) so that the non-arming device 10 (for example, the configuration shown in FIG. 1) can identify the radio wave from the commander. It is generated and added to the mixer 16. The command input device 17 is used by the commander to input a command for non-arming, and is, for example, a push button switch or the like.

In the case of the second reference example , when the instructor operates the command input device 17 to issue a non-arming command, the output of the command input device 17 is added to the mixer 16, where an identification signal is generated. After being mixed with the identification signal of the device 7, it is added to the transmitter 8. As a result, the transmission signal is modulated by the identification signal changed by the command, and the output of the transmitter 8 is radiated from the antenna 21 as a radio wave 22. The non-arming device 10 that receives the radio wave 22 with the antenna 20 non-arms the fuze. In this case, a plurality of non-arming devices can be operated at the same time.
