Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.

As shown in fig. 1, a schematic structural framework is provided for an embodiment of a ferrite phase shifter decoding control device 10 of the present invention, the ferrite phase shifter decoding control device 10 is suitable for controlling a phased array antenna unit, and includes:

the decoding control device 10 is used for decoding and gating the received phase-shift code, generating a control pulse and sending the control pulse to at least one driving circuit 20, and the driving circuits 20 are used for amplifying the received control pulse;

the number of the driving circuits 20 is the same as the grouping number of the ferrite phase shifters, and each driving circuit 20 controls one group of ferrite phase shifters in a one-to-one correspondence manner.

It should be noted that the control pulse includes the back address information, and may be used to gate the back-end driving circuit 20.

For example, assuming that the 3 th ferrite phase shifter groups a, b and c are controlled after decoding, the control pulse is sent to the corresponding driving circuit 20 for controlling the 3 ferrite phase shifter groups, and the control pulse is amplified, thereby controlling the ferrite phase shifters in the 3 ferrite phase shifter groups.

It should be noted that, the ferrite phase shifters may be divided into N groups in advance according to the distribution of the ferrite phase shifters, and the phase shift code of each group of phase shifters is calculated by one driving circuit 20, so that N driving circuits 20 may be provided. Thus, a group of phase shifters corresponding to one circuit board are formed, and a plurality of circuit boards are communicated with an upper computer at the same time and calculate a control mode of phase shifting codes.

The decoding control device 10 integrates a plurality of control circuits into one functional unit, reduces connecting cables, optimizes an antenna structure, and for example, may be composed of a power supply circuit 13, a communication interface circuit 11, and a decoding circuit 12.

The communication interface circuit 11 can use 5 pieces of AM26LS32AC and 1 piece of AM26LS31C to receive phase shift code data, a read/write signal, a reset signal, a set signal and an address signal sent by an upper computer respectively; a fault detection signal of the phase shifter is received. The address signal is decoded by the 74LS154 on the board, and the input 7 is the address, thus realizing the control of 128 groups of phase shifters. The phase shift code data, the read-write signal, the reset signal, the set signal and the decoded address signal are sequentially input to the 128-path driving circuit 20 at most through a plurality of 54HCT245 chips and HCPL-2430 optical coupling isolation chips on the board, and the control on 128 groups of phase shifter assemblies at most is realized. Meanwhile, fault detection signals of each group of phase shifter assemblies can be received and fed back to the upper computer.

Optionally, in some possible embodiments, the decoding control device 10 further includes: and the power supply circuit 13, wherein the power supply circuit 13 is used for supplying power to the communication interface circuit 11 and the decoding circuit 12.
