Beehive Monitoring | I Dadan and Paul Ukrainian | Data redundancy

    Inside the Japanese Beehive

    Bees need human care! And the further we go from the apiary, the better!

    The fact is that beekeepers, in the literal and figurative sense, drive bees into narrow frames.
    And this confirms the photo from the cap - insects build honeycombs of that thickness and orientation, which they need, and not us.

    The second confirmation that we do not know what the bees really need is the variety of systems and structures of the hives, since at least it was determined that for a successful wintering, 8 "standard" frames of 300x435 mm are needed.

    That is, these very frames were invented for the convenience of selecting honey, while the nest of bees in the construction of Prokopovich (the inventor of the hull hive) was not disturbed.

    If in the first article I analyzed the necessity of analyzing not only weight, temperature and humidity using the example of existing systems, the second publication was an attempt to find the cheapest technical implementation of monitoring, now I will try to make out how and what you can and should “write” from the hive.

    In fact, there is not and cannot be a “perfect” hive — there is a volume that is comfortable for a particular bee family to live in certain environmental conditions.
    And given the tendency of these insects to propolise all the cracks, it is very difficult to automate the process of changing the geometry of the dwelling.

    Ideally, it would be desirable to get a volumetric temperature map of the hive - in order to know the size and condition of the bee club.

    This is possible either by installing dozens of temperature sensors, or by organizing a scanning system based on a contactless thermometer, finally using a thermal imager.

    By the way, there is also an option of how to "look" inside the hive, without unduly disturbing the bees either - designs with a mesh bottom are successfully used by many beekeepers.

    Super-large resolution is also not necessary - even a VGA-module is already quite a lot.

    Next - the sound - here the bikes are invented at every step - they write both certain frequencies and minute segments so that the beekeeper himself can listen.
    In fact, it will be enough to read the samples necessary for the Fourier / Hartley transformation - the frequency range is up to 1000 Hz.
    This will result in clear redundancy, but on the screen will be a beautiful three-dimensional image


    On the question of who needs it and is there a profit ?, I will answer - this is necessary for me and a few enthusiasts, beekeepers of the "day off".
    Hence, the number of hives under monitoring is about ten.

    What else troubled Habrovchan a lot? What changes in parameters do you need to run and do something?

    With relative!

    And do not run, and pay attention to the hive / family, in which the parameters are knocked out of the overall picture.

    For in fact, among beekeepers it is considered (and not without reason) that it is necessary to start at least three beehives, that is, in any case, there is always something to compare with.

    And finally, I can not touch the latest technical fabrications - that really probably should not make hell on the air with wireless devices.

    Although it is tempting to put in each hive on a bluetooth headset and not bother with the hardware.

    I believe that this is the last article on "spherical monitoring in a vacuum" - in the next publication on this topic I will try to give information on the implementation in hardware.

    It is possible that this will happen in the spring, with the purchase of bees, since it is not interesting to consider the system without being tied to the object for which it is intended.

    Until new meetings on the pages of Habr, Andrew.
