Abstract
The invention discloses a kind of frame losing detection method and system based on DSP, the present invention is contrasted by the data for sending the received frequency source combinations of DSP with initial data, DSP produces interruption when data are consistent, and the frame number sent and the counter accumulated value of DSP are combined in comparison frequency source after group；When numerical value is consistent, no frame losing is judged；When the counter accumulated value of DSP is fewer than the frame number that frequency source is sent, frame losing is judged.The present invention can solve the problems, such as that observation oscillograph is readily incorporated human error and is unable to quantitative analysis frame loss rate tester for a long time, and a kind of easily detection method is provided for production debugging.
Description
Technical field
The present invention relates to a kind of frame losing detection method and system, is particularly a kind of frame losing detection method based on DSP and is
System.
Background technology
At present, the method for frame losing being detected in answering machine communication process is that the id signal after demodulation is sent to oscillograph
On, to determine whether frame losing by way of whether observation oscilloscope there is signal notch in refresh process.In practical application
In, it is necessary to for a long time observation oscillograph, it is easy to bring visual fatigue and be readily incorporated human error, bring very big work
Amount and inconvenience.Using DSP, i.e. digital signal processor assists frame losing detection to can solve this problem.
The content of the invention
Present invention aims at a kind of frame losing detection method and system based on DSP is provided, solve conventional artificial observation and show
The problem of ripple device is readily incorporated human error.
A kind of frame losing detection method based on DSP concretely comprises the following steps：
First step frame losing detects
DSP often receive a set of frequencies source combination send data contrasted with initial data, when received data with
When initial data is consistent, then DSP is produced and once interrupted, and counter adds up to remove in the lump and interrupts.When the data received with it is original
When data are inconsistent, then interruption is not produced and counter does not add up.
Second step frame losing is analyzed
Stop frequency source is combined, and the frame number and the counter accumulated value of DSP that frequency source combination is sent contrast, when numerical value one
During cause, no frame losing is judged；When the counter accumulated value of DSP is fewer than the frame number that frequency source is sent, frame losing is judged.
A kind of frame losing detecting system based on DSP, including：Frequency source combination, director data processing combination and DSP frame losings inspection
Survey module.Wherein connection, director data processing combination and DSP frame losing detection modules are combined in frequency source combination with director data processing
Connection.
More preferably, wherein the function of frequency source combination is generation modulated signal；The function of director data processing combination is pair
Modulated signal is demodulated；The function of DSP frame losing detection modules is to carry out frame losing detection and analysis to the data after demodulation.
The frame losing that the method for the present invention is applied to answering machine detects, and can solving tester, observation oscillograph is easy for a long time
The problem of introducing human error and being unable to quantitative analysis frame loss rate, a kind of easily detection method is provided for production debugging.
