Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the specific implementation method of the shooting range safety control system provided by the present invention is as follows:

[0022] The first step is to select the modulation system of the security control command according to the working environment of the security control system.

[0023] The present invention designs two different modulation systems of security control commands for different working environments of the security control system. In a high signal-to-noise ratio environment, the modulation system based on the combination of PCM-PSK-FM and the main letter security control system is selected. For the signal-to-noise ratio environment, choose the modulation system based on the combination of PCM-DS-BPSK-FM and the main letter security control system.

[0024] In the second step, the transmitting en...

Abstract

The invention discloses a range safety remote control system, and belongs to the technical field of range safety remote control. The range safety remote control system comprises the following steps that step 1, a modulation system of a safety remote control instruction is selected according to a working environment of the safety remote control system; step 2, a transmitting end of the safety remote control signal modulates the safety remote control instruction according to the modulation system selected by the step 1; step 3, a receiving end of a safety remote control signal demodulates a received signal according to the modulation system selected by the step 1 and recovers the safety remote control instruction; step 4, the receiving end of the safety remote control signal judges various safety remote control instructions recovered in the step 3; and step 5, a safety remote control object implements corresponding safety remote control measures according to the correct safety remote control instruction judged in the step 4. According to the range safety remote control system, a virtual instruction rate under the high signal-to-noise ratio environment and a missed instruction rate under the low signal-to-noise ratio environment are reduced, so that the security and the reliability of the safety remote control system are improved.

Description

technical field [0001] The invention belongs to the technical field of shooting range safety control, and in particular relates to a novel shooting range safety control system. Background technique [0002] The safety remote control (referred to as safety control) system is mainly used for the safety control of spacecraft and aircraft during the launch test at the shooting range. security, it is necessary to implement security control measures such as self-destruction. Considering the special mission background, the shooting range security control system has special requirements in terms of security, confidentiality and system reliability. In terms of security and confidentiality, the shooting range security control system needs to minimize the probability of false commands to prevent the target from being accidentally bombed by "false commands" caused by intentional or unintentional interference during normal flight. At the same time, in terms of reliability, the mission ...
