That is to say I want to know where the material is, when it moved,
If using c # development have what hardware is to support these function??
Haven't played, now the company have this demand,
Look at elder the great god, and he,
CodePudding user response:
Iot itself is not hardware support, Internet of things device is actually a small computer, there runs a small Windows, Linux system, such as your device will automatically open monitoring service, and then through the various ports and need these data interaction, so... You first take a look at the tree blackberry pie 'orange sent all sorts of Pi and other iot devices such as how to develop better,CodePudding user response:
This requires much rfid reader antenna,Calculation is not difficult, read rfid in set to continuous, actually he is to you don't need training in rotation
Issuing records EPC, dar good correlation,
As for other requirements, I said, according to the area of half warehouse at least 20 antennas,
For orientation, you can as a chessboard grid, an antenna, a grid
PS scope of rfid is read, that is to say you may have multiple antenna can read the same label, so how to accurately according to the strength judgment he most likely in the target area is behind you, (and of course you can put the antenna power adjustable weak)
CodePudding user response:
This design idea is good, but the actual operation is a big problem no, small problems,How to design the antenna distribution, how to adjust the antenna power intensity,
Using active tags, or passive tag,
How many antenna interference shielding, how to distinguish between strong and weak,
How to label, metal interference
Problems, active tags many times more expensive than passive table sign, general place, resistance to metal tag is more expensive than ordinary label, at the same time, you have to stick to good, otherwise the passive tag induction coil area is not enough, do not produce enough voltage to power a chip, he also can't read,
CodePudding user response:
Luqiao charges are commonly used active resistance to metal label, it's owners pay,But the factory warehouse, generally can't afford to use this, just like a passive cost is close to 1 piece, your o

Thanks for everybody, I now want to do here is that the trajectory tracking production materials, in general, the location of the label is relatively fixed, such as the material to be produced should be put in to production, is the production of material should be put beside the machine rack, I looked at some RFID information, I want to A level of about 100 square meters of space 10 antenna, then reads the 10 antenna information, according to what I think, the ten antenna capture the label should be repeated, such as the distance of 1 antenna capture A label is 5 meters, 2 antenna capture to the distance of A label for the 7 m, and so on,,, so I can use these information to calculate the material label where is closer, thus it is concluded that the label position, and then upload the information on grid graph, on punctuation,Haven't played with these things, I want to do, don't know, in addition to the frequency spectrum interference source outside of what need to be aware of??

I am looking for a solution, I demand compared to simple, only need material safety stock, no tracking trajectory,CodePudding user response:
