Number.
In practical applications, the detection data of acquired electromagnetic wave energy is detected for same material to the application
The detection data of the electromagnetic wave energy of acquisition sets one in the receiver and matches with the material for the specific material
Initial threshold energy, reception when which is set in the energy that receives when no material stops and has material blocking
Between the energy arrived.When the energy received is higher than the initial threshold energy, determine to stop without material;When the energy received
When lower than the initial threshold energy, it is determined with material blocking.It is consequently formed to material whether there is or not detecting, obtains electromagnetic wave energy
Detection data.
In practical material monitoring process, attachment may be will form on transmitter, for example, dust stratification, attachment is to transmitting
The electromagnetic wave energy that device is launched, which is formed, to be absorbed or reflects, so that the electromagnetic wave energy that receiver receives can reduce.Having
In body material monitoring process, the variation of attachment on transmitter increases for example, attachment increasingly accumulates, for another example, attachment because
It shakes and partially falls, so that the detection data for the electromagnetic wave energy that receiver detects constantly changes.
Step S12, present threshold value energy is obtained.
Present threshold value energy is equipped in receiver, to compare the electromagnetic wave energy received and present threshold value energy
Compared with to determine whether there is material blocking.For specific material, one is preset in the receiver and is matched with the material
Initial threshold energy is as present threshold value energy, in electromagnetic wave level switch original application, present threshold value energy is obtained, to obtain
Take pre-set initial threshold energy.
It should be pointed out that the successive description in the application to above-mentioned steps S11 and step S12, is not offered as, in reality
In, it is necessary to be to first carry out step S11, then execute step S12 again.In practical applications, step S11 and step S12 exist
There is no successive point when execution.

Amount is changed, and can be characterized and be formd attachment on transmitter, the energy that attachment launches transmitter formed absorb or
Person's reflection, so that the energy that receiver receives accordingly decreases, is changed to close to the present threshold value energy, determines
It needs to be adjusted present threshold value energy, according to the variable quantity being changed close to the present threshold value energy, to current
The adjustment of threshold energy progress Similar trend.Alternatively, if obtaining the electromagnetic wave energy detected when no material stops
Situation of change is changed away from present threshold value energy, can be characterized the attachment part formed on transmitter and be fallen, make
The energy that receives of receiver correspondingly increases, be changed, also determine to need to working as away from the present threshold value energy
Preceding threshold energy is adjusted, according to the variable quantity being changed away from the present threshold value energy, to present threshold value energy into
The adjustment of row Similar trend.
By the example scheme, it can be realized the receiver present threshold value energy that voluntarily dynamic adaptable adjusts, adapt to
The accumulation of attached crop or present threshold value energy adjusting demand under situation is fallen on transmitter.
By the example scheme, it can stop to avoid present threshold value energy in no material and there is material blocking to detect
The interval range that is formed of both energy except, no material can also be overcome to stop and have material to stop the energy detected excessively
The problem of close to present threshold value energy, and then improve the reliability detected to material.
