The invention discloses a kind of substation secondary device network communication performance test analysis device, including being used for processing two
The host computer 11 of the operational data of secondary device 15, the DSP master controllers 12 being connect with above-mentioned host computer, for secondary being set above-mentioned
Standby initial data transfer further includes above-mentioned primary data being converted into the data-interface 13 of above-mentioned DSP master controllers
The network controller 14 of legal form that can be received by above-mentioned DPS master controllers.Wherein, in intelligent substation secondary device number
It is optical fiber interface 131 according to interface 13, the 13 of secondary device are electric signal interface 132 in traditional substation.
Host computer 11, which refers to, can directly send out the computer of manipulation command, i.e. other in PC, usually performance relative system
It is all in the more powerful host of computer and processing substation secondary device network communication performance test analysis system secondary to set
It is standby, i.e. the processing center of the operational data of slave computer.
Host computer 11 is attached by serial line interface and DSP master controllers 12, usually used SPI serial line interfaces, certainly
It can also be connected by other interfaces, such as the computer interfaces such as USB, HDMI, DP.In practical operation, it is contemplated that different
The model of host computer PC, and the data transmission of host computer and DSP master controllers is without the communications of the interfaces such as HDMI, DP
Speed is generally connect using the SPI serial line interfaces of host computer with DSP master controllers.
It is understood that due in most cases, operating voltage and 11 interface of host computer of DSP master controllers 12
The voltage of output is different, therefore master controller expansion module is accessed between host computer and DSP master controllers, to be carried out to voltage
Conversion.Main control expansion module includes the electronic components such as battery, button, FLASH, SDRAM.Different host computer interfaces and DSP
Master controller connects, and needs using corresponding master controller expansion module.
In a kind of specific embodiment, host computer PC uses RS232 serial line interfaces, and MAX232 and QS3245 can be used
Chip realizes level conversion, i.e., by RS232 level conversions into the operation level of CMOS components in DSP master controllers.
The major function of DSP master controllers 12 includes being communicated with host computer, at the data between host computer
It puts and the control with network controller communication data, therefore, particularly may be divided into 3 modules：
Communication module, on the one hand for reading SV, GOOSE data and the electric sampled signal that above-mentioned host computer to be sent, separately
On the one hand it is used to return actuation time and the running-active status of above-mentioned secondary device to host computer.
Data dispose module, are on the one hand used for SV, GOOSE content augmentation data value to be sent for above-mentioned host computer and complete
Into the processing of electric sampled signal, the GOOSE on the other hand sending out above-mentioned secondary device stops parsing disposition, result is given above-mentioned
Host computer.
Communication control module, for giving the data that above-mentioned host computer is sent to above-mentioned network control according to secondary device type
Device processed, and the message that above-mentioned network controller provides is read in time.
DSP master controllers read SV, GOOSE data to be sent of host computer PC transmission and electric sampled signal, receive number
According to data filling and label is carried out to SV, GOOSE message later, meet Ethernet transmission data demand, to electric sampled signal into
Row processing；By the digital signal after filling or treated that electric sampled signal is sent to network controller.
In above-mentioned specific embodiment, host computer PC uses RS232 serial line interfaces, and master controller expansion module uses
MAX232 and QS3245 chips realize level conversion, by RS232 level conversions into the work of CMOS components in DSP master controllers
Level, and DSP master controllers use TMS320LF2407 processors.GOOSE, SV sample message and electric sampled signal and control life
The processing step that TMS320LF2407 progress data fillings and transmission are sent to by host computer is enabled, while TMS320LF2812 is controlled
Device processed can complete the work such as message receiving, parsing, and analysis result is sent to host computer.
Secondary device 15 had both included the tested intelligent electronic device at place in relay protection communication network in intelligent substation,
Including the tested electronic equipment in the relay protection communication network in traditional substation.Relay protection communication network institute in intelligent substation
The primary data that communicates with host computer of intelligent secondary device be digital signal, relay protection communication network institute in traditional substation
The primary data that communicates with host computer of secondary device be electric sampled signal, wherein, digital signal includes SV, GOOSE.
This, the data format that SV and GOOSE communicate for secondary device with host computer.
Intelligent secondary device in intelligent substation communicates the data-interface 13 that uses with host computer as optical fiber interface, tradition
Communicate with the host computer data-interface 13 that uses of intelligent secondary device in substation is electric signal interface.Due to the prior art
In, upper machine can not be handled not only by the digital signal that fiber interface inputs but also the electricity sampling letter that processing is inputted by electric signal interface
Number, it is therefore desirable to digital signal and electric sampled signal are handled by network controller 14 so that DSP master controllers can
It receives the signal and sends supreme position machine, to ensure that host computer obtains manageable data format.
The function of network controller can be realized by ethernet control chip, in above-mentioned specific embodiment, position machine PC
Using RS232 serial line interfaces, master controller expansion module realizes level conversion, DSP master controls using MAX232 and QS3245 chips
Device processed uses TMS320LF2407 processors, and network controller then uses DM9000 modules.
It is connected and leads to by parallel bus interface between TMS320LF2812 master controllers and DM9000 network controller
Filled GOOSE, SV are sampled message and electric sampled signal are sent to DM9000 network controllers, while DM9000 nets by letter
The message that outside is sent back can be uploaded to TMS320LF2812 controllers by network controller.DM9000 network controllers will be received from
The message of DSP is by optical fiber interface or message is sent to electric signal interface sending module tested intelligence or conditional electronic is set
Standby or network, while the message beamed back from tested intelligence or conventional electronic devices or network can be received.
DM9000 network controllers often send a message and generate an interruption, and record work is carried out to the time of this interruption
For sending time, an interruption is generated after this message returns to DM9000 network controllers by equipment under test, to this interruption
Time carry out record as receiving time, the difference of receiving time and sending time is just message in equipment under test or network
Transmission time can judge communication performance with this time.
