A self-identifying information filling method and device for command receivers

Abstract

The invention discloses a self-identification type information filling method and device for a command receiver. The method includes the following steps that: (0) password information pre-filled in the command receiver is acquired, and whether the password information is password information for testing is judged, if the password information is the password information for testing, a step (1) is executed, otherwise, no processing is executed; (1) external radio-frequency signals are acquired; (2) the radio-frequency signals are converted into intermediate-frequency signals, and password information contained in the intermediate-frequency signals is obtained; and (3) whether the password information contained in the intermediate-frequency signals in the step(2) is the password information for testing is judged, if the password information contained in the intermediate-frequency signals in the step(2) is the password information for testing, the method shifts to the step (1), otherwise, the password information contained in the intermediate-frequency signals in the step(2) is filled into the command receiver. The device includes a radio-frequency signal processing unit and a digital signal processing unit. Compared with the prior art, the self-identification type information filling method and device for the command receiver of the invention have the advantages of great convenience, high reliability, resource-saving performance and the like.

Description

technical field [0001] The invention relates to a self-identifying information filling method and device, in particular to a self-identifying information filling method and device for an instruction receiver. Background technique [0002] Instruct the receiver to receive the uplink signal sent by the ground station, demodulate the signal to obtain modulation information (or called password information), compare the information with the information pre-loaded in the product, and output the corresponding control signal. Command receivers usually need to set fixed password information for the assessment and verification of various routine tests, which is called test password information. The password information used in the test is a specific constant. The command receiver is mainly used in the aerospace field and is mounted on flying objects such as rockets and missiles. When participating in flight tests, the command receiver needs to be filled with unique password informatio...

Problems solved by technology

[0003] Limited by the existing command receiving system, when loading the unique password information of the command receiver, since there is no additional functional control circuit for the command receiver to identify and judge when loading, the process is more complicated, time-consuming and labor-intensive, and The reliability of routine tests cannot be guaranteed; in addition, due to the limited internal space of some types of flying objects, it is inconvenient to remove the command receiver and connect external hardware devices to load unique password information, so a loading method without connecting external hardware devices is urgently needed
