Description
Technical field
The utility model is related to a kind of microwave emitter, more particularly to a kind of antenna microwave control system.
Background technology
Data transmission is all much to use SPI between hardware both at home and abroad at present（Serial Peripheral
Interface）The communication mode of Serial Peripheral Interface (SPI) carries out data transmission.
Serial Peripheral Interface (SPI), SPI are a kind of communication bus of high speed full duplex, allow two or more equipment into
Row data exchange.Two communication between devices at least need three lines（One-way communication）Including main equipment DOL Data Output Line, clock
Signal and chip selection signal can also use four lines（Two-way communication）Including main equipment Data In-Line, the output of main equipment data
Line, clock signal and chip selection signal., it is specified that one of equipment is main equipment when multiple equipment communicates, remaining equipment is from setting
It is standby.Main equipment needs to reserve 4*N root lines at this time（N is from equipment number）, for controlling each from equipment, and each only from equipment
It needs to reserve 4 lines.Therefore serial peripheral equipment interface SPI can realize the communication between multiple equipment.
In practical solution, main equipment tends not to separate enough lines, but need to control it is multiple from equipment when（Such as
In this system, DSP（Digital Signal Processing-Digital Signal Processing）It needs to control many microwave ports, and
These microwave ports can not all be controlled by one from equipment, that is, need to go to control these microwave ends from equipment using two
Mouthful, then corresponding DSP mainboards need to reserve 8 lines to connect these from equipment, and in practical solution, DSP can only separate 4
Line is used to control from equipment）.
Utility model content
The purpose of this utility model is to provide a kind of antenna microwave control system, reduces interface quantity demand so that control
It makes more convenient.
What the purpose of this utility model was realized in：A kind of antenna microwave control system, including host computer, DSP number
Signal-processing board and polylith decode plate, and microwave unit is respectively connected on every block decoding plate；Host computer and DSP Digital Signal Processing
Plate is electrically connected, and the decoding plate is cascaded, and the decoding plate positioned at end is connected to the DSP digital signal panels
On；
The host computer gives DSP digital signal panels with microwave control code is sent；
The DSP digital signal panels generate microwave control message and are sent to parse above-mentioned microwave control code
Decode plate；
The decoding plate generates the radiofrequency signal of 2~18GHz to microwave unit to control microwave after message decodes；
The microwave unit generates to complete the reception to 2~18GHz radiofrequency signals, amplitude limit, filtering, frequency conversion
The intermediate frequency of 700MHz exports.
Compared with prior art, the beneficial effects of the utility model are, the utility model, which saves, is connected to DSP numbers
Interface quantity on signal-processing board so that control is more convenient.
As further limiting for the utility model, the decoding plate is connected to DSP Digital Signal Processing by SPI interface
On plate, decoding plate is attached also by SPI interface between each other.
As further limiting for the utility model, the SPI interface selects two-way communication, the SPI interface packet
Include four communication lines：Main equipment Data In-Line SDI, main equipment DOL Data Output Line SDO, clock signal SCLK and chip selection signal
CE。
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is DSP digital signal panels and decoding plate connection diagram in the utility model.
Specific implementation mode
A kind of antenna microwave control system as shown in Figs. 1-2, including host computer, DSP digital signal panels and more
Block decoding plate is often respectively connected with microwave unit on block decoding plate；Host computer is electrically connected with DSP digital signal panels, decodes plate
It is cascaded, and the decoding plate positioned at end is connected on DSP digital signal panels, decoding plate is connected by SPI interface
On DSP digital signal panels, decoding plate is attached also by SPI interface between each other, and SPI interface selects two-way communication
Mode, SPI interface include four communication lines：Main equipment Data In-Line SDI, main equipment DOL Data Output Line SDO, clock signal
SCLK and chip selection signal CE；
Host computer gives DSP digital signal panels with microwave control code is sent；
DSP digital signal panels generate microwave control message and are sent to decoding to parse above-mentioned microwave control code
Plate；
Plate is decoded the radiofrequency signal of 2~18GHz will be generated to microwave unit after microwave control message decoding；
Microwave unit generates 700MHz's to complete the reception to 2~18GHz radiofrequency signals, amplitude limit, filtering, frequency conversion
Intermediate frequency exports.
When utility model works, microwave control code is sent to DSP digital signal panels by host computer by serial ports,
After microwave control code receives parsing by DSP, it is converted into control message, which is sent to " decoding plate 1 ", " decoding plate 1 " connects
After receiving message, then the message is sent to " decoding plate 2 ", after " decoding plate 2 " receives message, then the message is sent to
" decoding plate n " ...." decoding plate 1 ", " decoding plate 2 ", " decoding plate n " etc. all parse the data received；Decode plate
The message received may not be to control this module, so the parsing module of different decoding plates is different, it is only right each to decode plate
The message for the microwave port that oneself can be controlled parses.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing performing creative labour can be special to some of which technology
Sign makes some and replaces and deform, these are replaced and deformation is within the protection scope of the present utility model.
