Description
Technical field
The present invention relates to a kind of production method of signal, the production method of pumping signal in especially a kind of senile experiment.
Background technique
In current industrial automation and process control application, there is a large amount of sensor, many procedure parameters are carried out
Measurement, such as：Pressure, temperature, toxic gas etc..These sensors become safer, higher efficiency and lower by industrial treatment
Cost.But different sensors have the monopolizing characteristic of oneself, to have different degrees of performance in long-term continuous work
Decaying and variation, therefore before sensor factory, aging can be sampled to the sensor of different batches, to obtain sensor
Performance parameter and index.
Equally, the different components in some special equipments due to working environment it is more severe, these will be in high/low temperature, low gas
It is carried out under the particular surroundings such as pressure, high heat and humidity, and loads different periodic excitation letters according to the different job specification of component
Number, long-time aging work is carried out, also needs to carry out component the senile experiment under varying environment after component is completed, to test
Whether the performance for demonstrate,proving component is up to standard.But the aging equipment that Today, most uses is carried out always using fixed pumping signal
Change, so that the agingtable of different sensors or different model component cannot be general, causes a large amount of device waste.
Summary of the invention
Present invention aims at the production methods for proposing pumping signal in a kind of senile experiment, solve existing method applicability
The problem of difference.
In a kind of senile experiment the production method of pumping signal the specific steps are：
The first step constructs pumping signal generation system
Pumping signal generation system, including：Information coding generation module, coded combination module and pumping signal generate mould
Block.It is described：
The function of information coding generation module is：Generate pumping signal information coding；
The function of coded combination module is：Information coding is combined；
The function of pumping signal generation module is：Generate pumping signal.
Second step information coding generation module generates pumping signal information coding
Information coding generation module is that a time interval decomposes the pumping signal of quasi- generation by 10us, is obtained each
Corresponding digital quantity in a time interval, and these digital quantities are converted into binary number, generate pumping signal information coding.
Third step coded combination module is combined information coding
Coded combination module obtains the signal period length of pumping signal information coding, then with 10us for a unit,
Each signal period is decomposed, 16 binary datas are converted into after decomposition, obtains period coded data.
Coded combination module is arranged binary pumping signal information coding by low to high, is then converted into
16 binary datas, i.e. pumping signal data；Period coded data is placed on front by coded combination module, and pumping signal data are placed on
Below, the two is combined, obtains data splitting.
4th step pumping signal generation module generates pumping signal
Pumping signal generation module controls agingtable device and receives data splitting, and extracting cycle is distinguished from data splitting and is compiled
Code data and pumping signal data, parsing generate pumping signal and export.
So far, pumping signal in senile experiment is produced.
This method can generate arbitrary excitation signal according to setting, easy to operate, practical.
Specific embodiment
Combined with specific embodiments below, invention is further described.It should be noted that：Following embodiment is only to illustrate this hair
It is bright and not limit the technical scheme described by the invention；Therefore, although this specification referring to following embodiments to the present invention
Detailed description is had been carried out, still, those skilled in the art should understand that, still it can modify to the present invention
Or equivalent replacement；And the technical solution and its improvement of all spirit and scope for not departing from invention, it should all cover in the present invention
Scope of the claims in.
In a kind of senile experiment the production method of pumping signal the specific steps are：
The first step constructs pumping signal generation system
Pumping signal generation system, including：Information coding generation module, coded combination module and pumping signal generate mould
Block.It is described：
The function of information coding generation module is：Generate pumping signal information coding；
The function of coded combination module is：Information coding is combined；
The function of pumping signal generation module is：Generate pumping signal.
The signal period of the quasi- pumping signal generated is 720us.
Second step information coding generation module generates pumping signal information coding
Information coding generation module is that a time interval decomposes the pumping signal of quasi- generation by 10us, is obtained each
Corresponding digital quantity in a time interval, and these digital quantities are converted into binary number, i.e., it is saved by 0/1, generates and swash
Encourage signal message coding：0000000 111,111 000,000 111,111 000000 ... ..B, wherein the first bit
Represent the height of amplitude in first 10us of excitation signal waveforms.
Third step coded combination module is combined information coding
The signal period length of coded combination module acquisition pumping signal information coding, signal period length 720us, so
Each signal period is decomposed, for the signal period of 720us long, is decomposed into altogether for a unit with 10us afterwards
72 10us time intervals are converted into 16 binary datas after decomposition, obtain period coded data.
Coded combination module is arranged binary pumping signal information coding by low to high, is then converted into
16 binary datas, i.e. pumping signal data；Period coded data is placed on front by coded combination module, and pumping signal data are placed on
Below, the two is combined, obtains data splitting：0x00 0x48 0x80 0x3f 0xe0 0xf0 0x00 0x00 0x00
0x00 0x00。
4th step pumping signal generation module generates pumping signal
Pumping signal generation module controls agingtable device and receives data splitting, and extracting cycle is distinguished from data splitting and is compiled
Code data and pumping signal data, wherein carrying out parsing acquisition to period coded data needs the time cycle of output drive signal,
Carrying out parsing acquisition to pumping signal data needs the signal data of output drive signal, ultimately generates pumping signal and exports.
So far, pumping signal in senile experiment is produced.
