Abstract
The utility model relates to a kind of supply voltage acquisition module of electric unmanned helicopter, is mainly used in the power-supply management system of electric unmanned helicopter, and system has related to unmanned plane, communication and electronic technology field.Lack management for existing electric unmanned helicopter power supply, the problem that safety coefficient is low, the utility model comprehensive simulation electronics and digital and electronic treatment technology have designed the supply voltage acquisition module of electric unmanned helicopter, this module can gather the change in voltage of single battery and power source integral in real time effectively, and provides high-precision image data for processor.The utility model is applied to electric unmanned helicopter and can effectively improves the power management efficiency of aircraft.
Description
Technical field
The utility model is mainly used in the power-supply management system of electric unmanned helicopter, and the technical field relating to comprises: electric unmanned helicopter, power management, circuit design and embedded development.
Background technology
Along with going deep into of unmanned plane technical research, people recognize that unmanned plane will be day by day remarkable in the effect of social production and life various aspects dearly.Use the integrated unmanned aerial vehicle of modernization new and high technology in part high risk industries, not only can increase work efficiency and quality, can also reduce operating cost, the more important thing is the risk that can reduce personnel's operation, the protection security of the lives and property.Along with scientific and technological progress and expanding economy, unmanned plane replaces traditional manpower to be engaged in excessive risk, highly difficult and high-intensity work has become inexorable trend.Research and development have the unmanned plane of low cost, high stability and widespread use, have become a kind of exigence.
At present domestic electric unmanned helicopter technology is also in elementary developing stage, most of electric unmanned helicopters are come from model plane development, the power electric of aircraft is directly powered by lithium battery mostly, power supply effectively do not managed and monitored, greatly having reduced the flight safety coefficient of aircraft.Meanwhile, the power electric of electric unmanned helicopter is generally by the string of many Battery packs and is combined into, and the power supply wiring more complicated of internal body, once wrong just has the danger that aircraft bombing occurs.The key of electric unmanned helicopter power-supply management system is the real-time change value that can gather accurately supply voltage, and the changing value of voltage is converted within the scope of the effective voltage that processor can process, in order to ensure the precision of measurement, should make the voltage range after converting be tending towards maximum.The utility model just based on above Demand Design the supply voltage acquisition module of a set of electric unmanned helicopter.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of electric unmanned helicopter supply voltage acquisition module is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
The utility model relates to a kind of electric unmanned helicopter supply voltage acquisition module, comprise reference source module and voltage acquisition module, the linear dividing potential drop part of voltage acquisition module is carried out dividing potential drop to magnitude of voltage to be detected, magnitude of voltage linear transformation to be measured has been arrived in the scope surveyed of processor, the treat pressure measurement value of differential amplification part after to dividing potential drop amplified, magnitude of voltage after processor is to dividing potential drop can improve sampling interval while carrying out A/D/ conversion, keep sampling precision, reference source module is made up of reference circuit, be used to differential amplifier circuit that reverse inter-input-ing voltage value is accurately provided.
The utility model compared with prior art has obvious advantage and effect.
The utility model has designed a kind of acquisition module of supply voltage, is applied to the power-supply management system of electric unmanned helicopter.
The electrical source of power of the electric unmanned helicopter of the utility model application is four groups of 6S batteries, and in parallel again after series connection between two, the direct supply voltage under security situation is greater than 44.4V.Power-supply management system will gather the voltage of single Battery pack and overall power supply respectively, and the voltage range of collection is respectively 22.2V-25V and 44.4V-50V, the single-chip microcomputer of processor adopting PIC series, and effective voltage scope is 0.5-5V, much smaller than virtual voltage.
In order to adjust voltage acquisition scope and to improve acquisition precision, mentality of designing of the present utility model is first input voltage to be carried out to linear dividing potential drop, the linear ratio relation who has not only reduced detection magnitude of voltage but also can keep change in voltage, in order to ensure partial pressure value accurately, in divider resistance, add adjustable resistance; After dividing potential drop, carry out ratio amplification through one-level amplifying circuit again, to improve acquisition precision, here select anti-phase proportional difference amplifying circuit more effectively, in-phase input end is the magnitude of voltage after dividing potential drop, inverting input is produced as shown in Figure 1 by reference source module, and the reference source is here based on reference diode LM136, and amplifier is selected LM385,12V power supply, concrete as Fig. 2.Adopt above-mentioned module voltage acquisition amount can be controlled to 0.7V-4.8V, wherein the lower limit of 0.7V can ensure the conducting of diode in module below.
Embodiment of the present utility model is provided in detail by following embodiment and accompanying drawing.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Embodiment
Below in conjunction with accompanying drawing and embodiment, to provide concrete embodiment, structure, feature and function to be elaborated as follows according to the utility model:
A kind of electric unmanned helicopter supply voltage acquisition module, comprise reference source module and voltage acquisition module, the linear dividing potential drop part of voltage acquisition module is carried out dividing potential drop to magnitude of voltage to be detected, magnitude of voltage linear transformation to be measured has been arrived in the scope surveyed of processor, the treat pressure measurement value of differential amplification part after to dividing potential drop amplified, magnitude of voltage after processor is to dividing potential drop can improve sampling interval while carrying out A/D/ conversion, keep sampling precision, reference source module is made up of reference circuit, is used to differential amplifier circuit that reverse inter-input-ing voltage value is accurately provided.
