In the table: D is the circulation yardage for decimal number C for binary number R
At first carry out following operation in use:
1. earlier fixed cover 5 is installed on the stationary shaft 4, again circulating code disk 6 is sleeved on the fixed cover 5.
2. at first Hall element 3 is packed on the fixed mount 2, then fixed mount 2 is installed on the set collar 1.
3. wind direction is installed on stationary shaft 4 at last or is flowed to mark, promptly become a complete measurement wind direction or the instrument of the flow direction.
The utility model principle of work:
Because wind direction or flow to that target is pointed to and the null axis of circulating code disk 6 to location and installation on same stationary shaft 4, promptly wind direction or flow to mark and circulating code disk 6 together with the wind or circulate and move.As shown in Figure 1, five Hall elements 3 (corresponding with five reflected code formula magnets 8) straight line row be contained on the fixed mount 2, and fixed mount 2 is installed in the top of circulating code disk 6, and magnet produces the output of " 1 " signal near Hall element 3.And the corresponding Hall element 3 of every magnet, so when wind or stream depart from the arctic, produce to such an extent that signal is determined the wind direction or the flow direction (as: 00000,01100 according to magnet and Hall element 3 are close, 10100,11000 ... Deng, be regulation: north, east, west, south ... Deng).
The making in the prior art and unavoidable error that tolerance produced is installed might surpass the unit quantity of the lowest order of reading.The utility model such as table 1 and shown in Figure 4: binary code is as 00001 to 00010, wherein C
0Become 0, C by 1
1Become 1 by 0, promptly two-digit changes.And any number that reflected code is represented adds 1 or subtract at 1 o'clock, has only a binary digit to change, as 00001 to 00011, and R wherein
0Be 1 constant, R
1Become 1 by 0.So data accurately and reliably.Specifically referring to table 1.
