Abstract
The invention relates to a manufacture method for an air flow sensor test platform, and relates to the field of electronics. The air flow sensor test platform comprises an upper computer, a test bench, a signal display, an air blower, a frequency converter and an air blowing pipeline. The test bench supports the air blowing pipeline, the upper computer is connected with the frequency converter, and the frequency converter is connected with the air blower. The air flow sensor test platform manufactured by the above method can adjust the speed of a motor of the air blower conveniently, and is high in air flow sensor calibration efficiency, and can achieve automatic acquisition and calibration, and is high in calibration output precision.
Description
Technical field
The present invention relates to person in electronics, be specifically related to a kind of manufacture method of air flow sensor test board.
Background technology
At present, the air flow sensor test board applied in the industry is all adopt mechanical switch to control fan blower flow, and what control flow counts by the restriction of number of switches, when needs increase is counted, needs the quantity increasing mechanical switch, wastes time and energy.Adopt traditional approach one by one go by mechanical switch, the problems such as calibration efficiency is not high, and output accuracy is low can be caused.
Summary of the invention
The object of the invention is the manufacture method providing a kind of air flow sensor test board, cannot to the accurate control problem of air mass flow for general air flow sensor test board.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: the air flow sensor test board of manufacture of the present invention comprises host computer one, testboard bay one, Signal Monitor one, fan blower one, one, frequency converter and blowing line, testboard bay plays a supportive role to blowing line, host computer is connected with frequency converter, and frequency converter is connected with fan blower.Of the present invention convenient to blower motor speed governing, calibration air flow sensor efficiency is high, can realize automatically gathering calibration, and calibration output accuracy is high.Described host computer installs the software program oneself write, it is characterized in that controlling frequency converter thus control the running of fan blower and the flow sensor raw voltage signals detected is gathered, filtering and calculating, again the data calculated are transferred in air flow sensor, air flow sensor are exported and the strict corresponding voltage signal of flow value.Described Signal Monitor, is characterized in that the voltage, the current signal that show input and output.
The present invention has following beneficial effect:
1, motor speed is fast easy to adjust.
2, calibration efficiency is high, can realize automatically gathering calibration.
3, output accuracy is calibrated high.
Accompanying drawing explanation
Fig. 1 is the air flow sensor testing bench structure schematic diagram that the present invention manufactures.
Embodiment
With reference to Fig. 1, first air flow sensor is put into blowing line, connect the data line of air flow sensor and computer, the rotating speed of motor is controlled by control that in computer, we write ourselves and test procedure, motor is run according to different rotating speeds, to produce different air mass flows, computer gathers the raw voltage signals of different flow lower sensor simultaneously, then filtering and mathematical operation process is carried out, the magnitude of voltage making sensor export us to want, if there is error, directly can revise the original value in computer, again new data value is transferred to sensor after calculating again, do not need the resistance device adjusting sensor circuit.Therefore easy to use, precision is high.
