The size of first threshold or Second Threshold is relevant with the color of working environment, in embodiment one
White ambient be an example, substantially can select random color, such as: black
Color, redness or Lycoperdon polymorphum Vitt etc..Only the intensity level of the light corresponding to each color different and
, the numerical value after this light intensity is changed by A/D with voltage represents, such as: black
Corresponding intensity level is 200, and the intensity level of white correspondence is 3600, and red corresponding intensity
Value is 3000 etc..Therefore, it can the intensity level by environmental colors and arrange corresponding pre-
If threshold value.The scope of above-mentioned first threshold and the scope of Second Threshold can be according to actual need
Want, be set to a certain point value, a certain value range or the sets of threshold values of certain several value range composition, its
Concrete numerical range also can be different according to the difference of detection environment.Due to first threshold pair
Answer is that self-moving device is in uninflated position, and Second Threshold corresponding be from mobile dress
Put the position having been raised to a certain height, for same detection environment, self-moving device
After rising, the reflective distance of signal becomes greatly therewith, causes signal intensity cutting to a certain extent
Weak, therefore, regardless of both concrete numerical value, first threshold must be more than Second Threshold.
Such as: under white working environment, possible first threshold is 3000, and Second Threshold is 1800.
And so-called useful signal, it is simply that meet the signal that predetermined threshold value requires.As described above, by
Can be certain point value, a certain value range or the threshold value of certain several value range composition in predetermined threshold value
Group.When predetermined threshold value is point value, the intensity only receiving signal is more than or equal to predetermined threshold value,
It can be considered as just useful signal;When predetermined threshold value is a certain value range or certain several value range group
Become sets of threshold values time, only when receive signal intensity be in this predetermined threshold value magnitude range it
In or scope group within the scope of, can be considered as just useful signal, less than or greater than this interval
It will be considered as invalid signals.Even if it is to say, receive pipe to have received signal, but should
If the intensity size of signal does not meets the requirement of predetermined threshold value, it is still invalid signals, and this biography
Sensor is still judged as breaking down.
In order to ensure Detection results, the floor surface below described base plate can with all white or
Person is the most white, when the most mobile described processing means is in detection pattern, and described
That penetrates pipe launches the direction above ground portion towards white.So may insure that signal is at reflection process
In only have the least weakening and loss, once go wrong, be exactly that transmitting tube or receive is managed certainly
Problem, and then improve testing result accuracy.In addition, whole operation ring can be made
Border is the surface of white surface or other solid colors, it is also possible to only at operation surface
Local arranges signal sensitizing range, equally gets a desired effect.
