Description
Technical field
The present invention relates to a kind of sensor electrical source module, belong to alcohol detection field.
Background technology
In white wine manufacturing industry, usually need to detect the alcohol content of wine.At present, measure alcohol wine degree and usually use alcoholometer, alcohol meter.Alcoholometer is different according to alcohol concentration, and proportion is different, and the principle that buoyancy aid sinks to the volume that arranges wine liquid in wine liquid different manufactures.But the measurement result accuracy that existing alcohol meter measures alcohol method is not good, and need manually to participate in also record one by one, waste time and energy.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one and can reduce and filter Wen Bo, and make the sensor electrical source module of out-put supply signal stabilization.
A kind of sensor electrical source module of the present invention, for connecing wine detecting device testing circuit, comprise power management module, the first electric capacity be connected with described power management module and the second electric capacity, described power management module has power input pin, ground connection input pin, ground connection output pin, positive pole output pin and negative pole output pin, described power input pin and ground connection input pin are connected with the positive pole of the first electric capacity and negative pole respectively, and external input power, described ground connection output pin, positive pole output pin is connected with the negative pole of the second electric capacity and positive pole respectively, and positive pole output pin and negative pole output pin form the power output end of sensor electrical source module.
Further, described power management module has enable control pin.
By such scheme, the present invention at least has the following advantages: by the connection of power management module and the first electric capacity, the second electric capacity, thus the out-put supply of the faint and signal stabilization of civilian ripple is provided to the sensor connecing wine testing circuit, improve the accuracy of detection that connects wine testing circuit and detect stability.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of sensor electrical source module of the present invention.
Embodiment

See Fig. 1, a kind of sensor electrical source module described in a preferred embodiment of the present invention is used for connecing wine detecting device testing circuit, and this sensor electrical source module comprises power management module U1, the first electric capacity C1 be connected with described power management module U1 and the second electric capacity C2.Described power management module U1 is the modular power supply chip of high precision that inside comprises the process of a series of signal such as voltage stabilizing, noise reduction, and it has power input pin 2, ground connection input pin 1, ground connection output pin 4, positive pole output pin 3 and negative pole output pin 5.Described power input pin 2 and ground connection input pin are connected with the positive pole of the first electric capacity C1 and negative pole respectively, and external input power, described ground connection output pin 4, positive pole output pin 3 are connected with the negative pole of the second electric capacity C2 and positive pole respectively, and positive pole output pin 3 and negative pole output pin 5 form the power output end of sensor electrical source module.Described power management module U1 also has enable control pin (CTRL pin).
The sensor power module is high-precision sensor power module, it can reduce and filter Wen Bo, stable power supply signal is provided, the principle of work of this sensor electrical source module is as follows: input power VIN converts through power management module U1, export civilian ripple faint, the power supply of signal stabilization, CTRL pin is the enable control pin of power management module U1, when connecing wine detecting device testing circuit and not needing working sensor, only need power management module U1 to carry out setting to CTRL pin can control sensor and whether work on power, thus reduce power consumption greatly, extend the serviceable life connecing wine detecting device testing circuit.
In sum, by the connection of power management module U1 and the first electric capacity C1, the second electric capacity C2, thus provide the out-put supply of the faint and signal stabilization of civilian ripple to the sensor connecing wine testing circuit, improve the accuracy of detection that connects wine testing circuit and detect stability.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
