Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Refering to shown in Fig. 1, the present invention provides a kind of contactless Measuring Moisture Content of Tea based on on-site supervision to measure system, including
Processor of single chip computer 1, electromagnetic valve 2, microwave remote sensor 3, touch screen the 4, first Wireless transceiver module the 5, second Wireless transceiver module 6
With on-the-spot computer 7, described electromagnetic valve 2, microwave remote sensor 3, touch screen 4 and the first Wireless transceiver module 5 all process with single-chip microcomputer
Device 1 connects, and described electromagnetic valve 2 is for controlling the switch of microwave remote sensor 3, and described first Wireless transceiver module 5 is wireless with second
Delivery module 6 wireless connections, described second Wireless transceiver module 6 is connected with on-the-spot computer 7.
The model of described processor of single chip computer 1 is Atmega64.This single-chip microcomputer has a characteristic that when working in 16MHz
Performance is up to EEPROM, 4K byte on-chip SRAM of In-System Programmable Flash, 2K byte of 16MIPS, 64K byte, 8 tunnels 10
Position ADC, 53 programmable I/O mouths, 2 serial ports.
Described first Wireless transceiver module 5 and the second Wireless transceiver module 6 all use 2.4G wireless module.It compares bluetooth
Its cost of goods manufactured is lower, it is provided that message transmission rate higher.Compare it anti-of the most free 27MHz wireless technology
Interference, maximum transmission distance and power consumption all far beyond.
The present invention uses microwave technology, due to microwave be wave-length coverage from 1m to 1mm, corresponding frequency from 300MHz to
The electromagnetic wave of 300GHz.The ability of material absorbing microwave, the ability of the material absorbing microwave that parenchyma loss factor is little is the most weak.Moisture
Son belongs to polar molecule, and dielectric constant is relatively big, and its dielectric dissipation factor is the biggest, has strong absorbability to microwave.And other is done
The dielectric constant of material is relatively small, and it is more much smaller than water to the absorbability of microwave.
After passing object due to microwave, intensity can weaken, and occurs decay and phase place to change.Containing of water is measured in reality
During amount because polarization the strongest hydrone the absorptance of microwave and other materials are had dramatically different (as: moisture is to microwave
Absorptance reaches 37:1 with coal to the ratio of the absorptance of microwave).So, in wet material, a small amount of change of moisture can be drawn
Play the great changes of microwave absorption amount.So, when microwave is by test substance, because absorption difference among determinand, can change
Becoming microwave intensity, phase and amplitude, effect is then relevant with the content of wherein water.
The operation principle of the present invention is, processor of single chip computer 1 controls electromagnetic valve 2 action in use, makes microwave remote sensor 3
Folium Camelliae sinensis is carried out moisture measurement, and measurement data is processed by processor of single chip computer 1, and is shown, simultaneously by touch screen 4
Being sent to on-the-spot computer 7 by the first Wireless transceiver module 5 and the second Wireless transceiver module 6, testing staff can learn tea in scene
The moisture figure of leaf.The present invention can carry out multinomial measurement by multiple electromagnetic valves 2 and microwave remote sensor 3.
Present invention have the advantage that
1, the present invention uses microwave technology, can penetrate measured matter, thus can not only measure the moisture on material surface, also can
Survey the moisture contained by material inside, make measurement result more accurate.
2, the present invention uses microwave technology can realize lossless and non-cpntact measurement, and power is low, the safest to personage.
3, the present invention uses 2.4G wireless technology, has that price is low, long transmission distance and an advantage low in energy consumption.
4, the spread speed of microwave is quickly, it is provided that one instantaneous, and accurate moisture numerical value, it is the most permissible
Detect the moisture in any material: coal, cement, sugar, corn, puffed rice, flour, seed etc..
Although being described in conjunction with the accompanying embodiments of the present invention, but patent owner can be in claims
Within the scope of make various deformation or amendment, as long as less than the protection domain described by claim of the present invention, all should
