Description

Technical Field

[0001] The invention relates to the technical field of small-caliber electronic time fuze information setting, and in particular to a fuze setting information compression encoding or decoding method. Background Art

[0002] Small-caliber electronic time fuze is an electronic fuze whose action mode and detonation time are controlled by an electronic movement. The action mode and detonation time and other information usually need to be set in real time according to the combat environment and target position. Muzzle setting is the best way to achieve real-time setting. Due to the structural limitations of the muzzle setting device, the information setting window is extremely short, only reaching tens to more than one hundred µs. In order to upgrade the existing ammunition fuze, more information needs to be set in the original muzzle setting device setting window. Only by further compressing the original information coding can the new needs be met. Summary of the invention

[0003] The present invention provides a method for compressing and encoding or decoding fuze setting information, which can effectively compress the muzzle setting information of an electronic time fuze, thereby achieving the purpose of setting more information in the same setting window.

[0004] The technical solutions to the above problems are as follows: A method for compressing and encoding or decoding fuze setting information comprises the following steps: S1, obtaining different continuous pulse groups and duty time intervals and their position numbers in sequence according to the pulse information in the acquisition code; S2, find the location of the continuous pulse group at the terminal and determine the terminal and location number; S3, if two or more docks are found, go to step S4; if only one dock is found, the data bit continuous pulse groups and the corresponding duty time interval position numbers need to be re-sorted according to the set data code length, the number of data bit continuous pulse groups before and after the dock, and the corresponding duty time intervals; S4, decoding subsequent data information according to a combination of the data bit continuous pulse group and the corresponding duty time interval.

[0005] Furthermore, the encoding is composed of a terminal continuous pulse group M, a long data bit continuous pulse group M1, a short data bit continuous pulse group M2, and a duty time interval including a short duty time interval T1 and a long duty time interval T2.

[0006] Further, the terminal continuous pulse group M consists of 9 continuous pulses, the long data bit continuous pulse group M1 consists of 5 continuous pulses, the short data bit continuous pulse group M2 consists of 2 continuous pulses, the short duty time interval T1 ≥ 2 continuous pulse time widths, and the long duty time interval T2 ≥ 3 continuous pulse time widths.

[0007] Further, the decoding includes start bit decoding, in which: A combination of a short duty time interval T1 and a short data bit continuous pulse group M2 is used to represent a 0 in a binary bit; A combination of a long duty time interval T2 and a short data bit continuous pulse group M2 is used to represent a 1 in a binary bit; A long data bit continuous pulse group M1 is used to represent 01 in binary bits.

[0008] Furthermore, the decoding also includes subsequent bit decoding, in which: The combination of short duty time interval T1 and short data bit continuous pulse group M2 is used to represent the same as the previous binary bit; The combination of long duty time interval T2 and long data bit continuous pulse group M2 is used to represent the opposite of the previous binary bit; A long data bit continuous pulse group M1 is used to represent 01 in binary bits.

[0009] In the present invention, the pulse encoding or decoding technology and the duty cycle encoding or decoding technology are innovatively proposed to integrate the pulse encoding or decoding and the duty cycle encoding or decoding method to achieve the purpose of compressing the set information. The code consists of a terminal continuous pulse group, a data bit continuous pulse group and a duty time interval. The characteristics are: the compression encoding or decoding method uses the comprehensive information of the number of data bit continuous pulse groups and the duty time interval to represent the binary information of the set information, which effectively ensures the further compression of the set information.

[0010] In the present invention, the binary bit information of the setting information is represented by the number of continuous pulse groups and the time interval between the pulse groups, which can specifically represent the binary bit information "0", "1" and "01". The compression encoding or decoding method is flexible and easy to implement, and can effectively compress the electronic time fuse muzzle setting information to achieve the purpose of setting more information in the same setting window.

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] like Figure 1 As shown, a method for compressing and encoding or decoding fuze setting information of the present invention comprises the following steps: S1, according to the pulse information in the acquisition code, different continuous pulse groups and duty time intervals and their position numbers are obtained in sequence. In this embodiment, the code consists of a terminal continuous pulse group M, a long data bit continuous pulse group M1, a short data bit continuous pulse group M2, and the duty time interval includes a short duty time interval T1 and a long duty time interval T2.

[0015] Among them, the terminal continuous pulse group M consists of 9 continuous pulses, the long data bit continuous pulse group M1 consists of 5 continuous pulses, the short data bit continuous pulse group M2 consists of 2 continuous pulses, the short duty time interval T1 ≥ 2 continuous pulse time widths, and the long duty time interval T2 ≥ 3 continuous pulse time widths.

[0016] S2, find the location of the continuous pulse group M of the terminal and determine the terminal and location number.

[0017] S3, if two or more docks are found, go to step S4; if only one dock is found, the data bit continuous pulse groups and the corresponding duty time interval position numbers need to be re-sorted according to the set data coding length, the number of data bit continuous pulse groups before and after the dock, and the corresponding duty time intervals.

[0018] S4, decoding subsequent data information according to a combination of the data bit continuous pulse group and the corresponding duty time interval.

[0019] The decoding includes start bit decoding, in which: the combination of short duty time interval T1 and short data bit continuous pulse group M2 is used to represent 0 in binary bit, which is simplified as: the combination of T1M2 represents 0 in binary bit. The combination of long duty time interval T2 and short data bit continuous pulse group M2 is used to represent 1, which is simplified as: the combination of T2M2 represents 1. The long data bit continuous pulse group M1 is used to represent 01 in binary bit, which is simplified as: M1 represents 01 in binary bit.

[0020] Decoding also includes subsequent bit decoding, in which: the combination of a short duty time interval T1 and a short data bit continuous pulse group M2 indicates the same as the previous binary bit, which is simplified as: the combination of T1M2 indicates the same as the previous binary bit. For example, if the current bit in the decoding is the third bit and the second bit is 1, the third bit is also 1. The combination of a long duty time interval T2 and a long data bit continuous pulse group M2 indicates the opposite of the previous binary bit, which is simplified as: the combination of T2M2 indicates the opposite of the previous binary bit. For example, if the current bit in the decoding is the third bit and the second bit is 1, the third bit is also 0. The long data bit continuous pulse group M1 is used to represent 01.

[0021] The fuze setting information compression encoding or decoding method of the present invention improves and compresses the pulse encoding of the existing setting information by effectively integrating the pulse encoding or decoding technology with the duty cycle encoding or decoding technology without changing the setting window, so that the setting information volume of the same setting window is nearly doubled, which can meet the needs of product upgrading and transformation. The setting information compression encoding / decoding method is a domestic original design, filling the gap in the domestic technical field.

[0022] Finally, it should be noted that the above-described implementation mode is only a preferred embodiment of the present invention to illustrate the technical solution of the present invention, and does not limit it, let alone limit the protection scope of the present invention; although the invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the protection scope of the claims.
