Because the transmission rate of Ethernet is very high, ethernet mac controller must possess suitable disposal ability, current Mainstream scheme is to use microprocessor or FPGA, and the present invention is built using FPGA, and compared with microprocessor arrangement, FPGA has more Strong parallel processing capability and upgradability, Simultaneous Stabilization is also more preferable, is quite suitable for big batch test data transmission field Close.
Vector modulator observing and controlling process plate is the printed circuit board (PCB) (PCB) of one piece of customization processing, and power supply is from outside straight Stream is powered, using Width funtion input DC/DC power supply chip LTM8027, externally fed voltage in vector modulator observing and controlling process plate Scope is 16 ~ 60V, because vector modulator observing and controlling process plate is directly connected with bay, is disturbed to reduce, external dc supplies Electricity need to use the linear power supply or high performance switch power supply of low ripple.
The core of vector modulator observing and controlling process plate is FPGA, and it is the maincenter part of whole TT＆C system, and its function is sharp Realized with finite state machine (FSM) technology of maturation, the Ethernet data control instruction from host computer can be received, and according to finger The difference of identification of function code is made, jumps to the different conditions of state machine, so as to complete the control of external instrument instrument, lock-out pulse production The switching of raw and state, communicate three zones with DAC chip inside vector modulator aerial array, wherein and with vector modulator DAC chip communication is the most key inside aerial array.With the maturation of manufacturing process, effective array element of some typical smart antennas Up to more than 3000, it means that the beam controlling system of antenna at least needs the DAC passages of 6000 tunnel independences, and due to phased array The harsh space limitation of antenna, configures independent DAC chip for each DAC passage and is difficult to, therefore existing vector is adjusted Device scheme smart antenna processed is using integrated channel quantity is more, control accuracy is high, external interface is succinct, low in energy consumption, small volume Single-chip multichannel DAC.Such DAC chip is the most typical with the AD5372/5373 of Aanlog Devices companies, its numeral control Interface processed is the line spi bus of industrial standard 4, therefore vector modulator observing and controlling process plate FPGA need to utilize its parallel advantage instantiation Multigroup spi bus transceiver, so as to reach the accurate width phase control to each bay.
Pass through aerial array test cable between vector modulator observing and controlling process plate and vector modulator aerial array to be measured Connection, to reduce cable signal line number amount, SPI clocks and SPI host datas transmitting terminal between multigroup spi bus can be multiplexed It is shared, but the choosing of SPI pieces must be implemented separately with SPI host datas receiving terminal, otherwise be unable to reach specify single to aerial array The control of vector modulator.
The main purpose of programmable power supply is to provide the various working powers needed for aerial array proper testing, need to use big work( Rate high-performance direct current power supply, the N8925A that it is moral company that typical products, which are, multiple power sources are used to combine if necessary to meet The needs of different antennae array, but require that the programmable power supply should possess Ethernet interface, so that observing and controlling computer host computer procedure The working condition of power supply can be set and monitored automatically by ethernet communication, improve testing efficiency.

Except the above-mentioned hardware composition part of TT＆C system, observing and controlling host computer procedure software is then another master of TT＆C system Part is wanted, the concrete function of observing and controlling host computer is realized by various dialog controls, and is reasonably classified.This implementation The observing and controlling host computer procedure of case can support synchronized-pulse control, antenna beam to control, T/R modules control, antenna condition monitors, Vector modulator observing and controlling handles onboard Flash controls, the extraction of vector modulator annulus data, transmitting calibration, reception are calibrated and Test data background process function, each function inside include different setting options and control button again.
The workflow of observing and controlling host computer procedure is：
The first step：It is prepared work, including antenna connection, probe positions initialization.
Second step：Detect vector modulator observing and controlling process plate and other instrument and meters whether successful connection.
3rd step：Successful connection then carries out the 4th step, and otherwise sending connection failure by observing and controlling computer prompts, and operator should Second step is retried after checking Ethernet connection.
4th step：Retaking of a year or grade vector modulator observing and controlling process plate FPGA program versions number.
5th step：The vector modulator observing and controlling process plate FPGA program versions number of retaking of a year or grade are normal then to carry out the 6th step, otherwise Again the 4th step is retried after burning FPGA programs.
6th step：Antenna self-test.
7th step：Antenna self-test normally then carries out the 8th step, otherwise provides self-test abnormal passage quantity and position, auxiliary Help antenna to repair troubleshooting, the 6th is retried after antenna maintenance.
8th step：Wait operating personnel to start specific function test, if function input then enters the 9th step, otherwise hold It is continuous to wait.
9th：It is different according to operating personnel's selection function, start corresponding automatic test operation.
In order to complete the multiple functions that foregoing host computer is supported, the observing and controlling that the implementation case gives complete set is upper Machine and vector modulator observing and controlling process plate communication protocol, using UDP message bag form, support full-duplex communication.It is wherein descending logical Letter agreement refers to be transmitted to the data frame of vector modulator observing and controlling process plate by observing and controlling host computer, is segmented into 3 kinds, the first is direct Handled by vector modulator observing and controlling process plate（Processing Frame, it is abbreviated as PF frames）, second then only by Vector Modulation Device observing and controlling process plate is converted into the ripple control motherboard that SPI forms are then forwarded to inner antenna to be measured, and itself is not handled （Forwarding Frame, it is abbreviated as FF frames）, the third had then both been handled by vector modulator observing and controlling process plate, had been converted into again SPI data formats issue the ripple control motherboard of inner antenna to be measured（Compound Frame, it is abbreviated as CF frames）.
Similarly, uplink communication protocol frame refers to is transmitted to the data of observing and controlling host computer by vector modulator observing and controlling process plate Frame, it can also be divided into 2 kinds：It is a kind of by vector modulator observing and controlling process plate receive after the downlink data frame that certain needs return data from Row produces（Protosomatic Feedback Frame, PFF）, it is another then be to connect the feelings of antenna ripple control motherboard to be measured Under condition, produced by antenna ripple control motherboard to be measured and finally transmitted to host computer procedure after vector modulator observing and controlling process plate transfer （Relay Frame, RF）.
It is descending with the specific form of uplink communication protocol frame and definition need to according to actual test it needs to be determined that, it is a kind of typical It is descending as shown with uplink communication protocol frame list.
As shown in Figure 2, complete observing and controlling host computer procedure flow chart is explained as follows：
The preparation of test is carried out first, such as antenna connection, probe positions initialization, front polarization alignment, antenna leveling, instrument Instruments and meters connection etc..Hereafter host computer procedure can be run, host computer procedure is surveyed first with Ethernet connected vector modulator Process plate and other instrument and meters are controlled, only can carry out subsequent step after connection is successfully established, connection otherwise can be provided and lose Prompting is lost, is retried after can now checking the connection of the netting twine between different instrument and meters and Ethernet switch, until successful connection.
, should to ensure the correctness of observing and controlling work because the processing core of vector modulator observing and controlling process plate is FPGA FPGA adds version retaking of a year or grade function, and host computer obtains current FPGA program versions number using Ethernet protocol, and with built-in mark Quasi- storehouse contrast, needs burning vector modulator observing and controlling process plate FPGA programs again if wrong.
Hereafter host computer procedure starts the self-test work to whole aerial array, and this passes through to vector where each array element Modulator DAC passages carry out write-in and the read back operation of specific data, so as to check single bay width phase control passage Validity realizes that last host computer can be provided in the presence of abnormal control passage quantity and position.Usually, even if having about 10% or so array-element antenna control is abnormal, also the performance of whole antenna will not be caused to significantly affect, if needs further dimension Repairing troubleshooting can be determined on a case-by-case basis by operating personnel.
After completing self-test work, host computer procedure entry instruction wait state, according to the input parameter of operating personnel and press Button selects, and realizes the extraction of vector modulator annulus data, transmitting calibration respectively, receives calibration totally 3 kinds of automatic test functions, is Coordinate this 3 kinds of automatic test, host computer procedure also supports each of manual control vector modulator observing and controlling process plate and antenna Kind state, respectively including synchronized-pulse control, antenna beam control, the control of T/R modules, antenna condition monitoring, vector modulator Observing and controlling handles onboard Flash controls and test data background process function.
Communication protocol and host computer flow between above-described observing and controlling host computer and vector modulator observing and controlling process plate Figure is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, not departing from, the present invention is whole Under body concept thereof, some changes and improvements can also be made, these should also be considered as protection scope of the present invention.
