Abstract
The utility model provides a numerical-controlled inflator pump, belongs to the field of inflator pumps, and is used for solving the problem of the existing inflator pump that the output air pressure value is inaccurate due to the situations of zero temperature drifting and air-pressure measuring temperature drifting. The numerical-controlled inflator pump comprises an inflator pump body, wherein a control unit and a temperature sensing unit which is electrically connected with the control unit are arranged on the inflator pump body; the control unit is connected with an engine on the inflator pump body and can control the engine to work. The numerical-controlled inflator pump has the advantage that the air pressure value is output accurately.
Description
Technical field
The utility model belongs to the gas-filled pump technical field, relates to a kind of digital control gas-filled pump.
Background technique
Along with improving constantly of people's economic level, automobile has entered into huge numbers of families, gas-filled pump also produces thereupon simultaneously, gas-filled pump is for inflating automatically tire and can controlling inner gas pressure so that automobile tire obtains suitable atmospheric pressure value, and gas-filled pump is generally simulation barometer air pump and ordinary numbers control shows gas-filled pump.But the problem that exists is: present simulation barometer air pump and ordinary numbers control show that the digital barometer of gas-filled pump all exists zero temperature drift and barometric surveying temperature drift, make that air pressure shows inaccuracy under special exceedingly odious weather environments such as extreme low temperature or high temperature, cause automobile tire to can not get suitable atmospheric pressure value.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, thereby has proposed a kind of digital control gas-filled pump that accurately control air pressure output exactly that can both air pressure under extreme low temperature, room temperature and high temperature condition environment shows.
The purpose of this utility model can realize by following technical proposal: a kind of digital control gas-filled pump, comprise gas-filled pump, it is characterized in that: the temperature induction unit that described gas-filled pump is provided with control unit and is electrically connected with control unit, described control unit is connected with motor on the gas-filled pump and can controls engine operation.
In above-mentioned a kind of digital control gas-filled pump, described control unit comprises single-chip microcomputer and the signal input unit that is connected with single-chip microcomputer, temperature-compensation circuit unit and signal output unit.
In above-mentioned a kind of digital control gas-filled pump, described temperature induction unit comprises the temperature transducer that several are connected with signal input unit in the above-mentioned control unit.
In above-mentioned a kind of digital control gas-filled pump, the air pressure display screen that is electrically connected with above-mentioned single-chip microcomputer is installed on the described gas-filled pump.
Compared with prior art, this numeral control gas-filled pump can detect collection to the temperature of gas-filled pump working environment, and the temperature information that collects is transported in temperature-compensation circuit unit and the single-chip microcomputer adopts the digital temperature compensation, self adaptive control and be that the modes such as FUZZY ALGORITHMS FOR CONTROL of parameter calculate the actual pressure value under the condition of different temperatures accurately with the temperature in the large-temperature range, the zero temperature drift that exists under the different temperatures and the situation of barometric surveying temperature drift have been eliminated, thereby accurately control gas-filled pump and offer the inner gas pressure value that tire is set, guarantee that tire obtains suitable air pressure.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this numeral control gas-filled pump comprises gas-filled pump, the temperature induction unit that gas-filled pump is provided with control unit and is electrically connected with control unit, and control unit is connected with motor on the gas-filled pump and can controls engine operation.
Control unit comprises single-chip microcomputer and the signal input unit that is connected with single-chip microcomputer, temperature-compensation circuit unit and signal output unit, and the air pressure display screen is installed on the gas-filled pump and with single-chip microcomputer and is electrically connected.Temperature induction unit comprises two temperature transducers that are connected with signal input unit in the control unit.Two temperature transducers are installed in respectively on the relative both sides of gas-filled pump, have difference (such as day side and the positive side of the back of the body) owing to consider the ambient temperature at the different avris of gas-filled pump place, can average then as the final ambient temperature that collects to the temperature information that these two temperature transducer collections come in the temperature-compensation circuit unit, the actual environment temperature of can more more fitting so a bit makes last air pressure export more closing to reality.
This numeral control gas-filled pump can detect collection to the temperature of gas-filled pump working environment, and the temperature information that collects is transported in temperature-compensation circuit unit and the single-chip microcomputer adopts the digital temperature compensation, self adaptive control and be that the modes such as FUZZY ALGORITHMS FOR CONTROL of parameter calculate the actual pressure value under the condition of different temperatures accurately with the temperature in the large-temperature range, the zero temperature drift that exists under the different temperatures and the situation of barometric surveying temperature drift have been eliminated, thereby accurately control gas-filled pump and offer the inner gas pressure value that tire is set, guarantee that tire obtains suitable air pressure.Thereby allow operator can intuitively understand the situation of output pressure by showing on the air pressure display screen for operator's observation the actual pressure value that calculates simultaneously.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
