Description
Technical field
The present invention relates to the production method of a kind of signal, particularly the production method of pumping signal in a kind of senile experiment.
Background technology
In current industrial automation is applied with process control, there is substantial amounts of sensor, many procedure parameters are measured, as: pressure, temperature, toxic gas etc. These sensors become safer, higher efficiency and lower cost by industrial treatment. But different sensors has the monopolizing characteristic of oneself, thus having performance degradation in various degree and change in long-term continuous operation, therefore before sensor dispatches from the factory, can the sensor of different batches be sampled aging, to obtain performance parameter and the index of sensor.
Equally, different assemblies in some special equipments are more severe due to working environment, these to carry out under the special environments such as high/low temperature, low pressure, high heat and humidity, and load different periodic activation signals according to the different job specification of assembly, carry out long-time aging work, also needing assembly is carried out the senile experiment under varying environment after assembling components completes, whether the performance to verify assembly is up to standard. But the aging equipment that Today, most uses, is all adopt fixing pumping signal to carry out aging so that different sensors, or the agingtable of different model assembly can not be general, cause the waste of substantial amounts of device.
Summary of the invention
Present invention aim at proposing the production method of pumping signal in a kind of senile experiment, the problem solving existing method applicability difference.
The concretely comprising the following steps of the production method of pumping signal in a kind of senile experiment:
