Abstract
The utility model relates to a multi-circle electronic coder, and particularly relates to a multi-circle electronic coder consisting of a singlechip, two electronic compass chips and magnets. According to the technical solution adopted by the utility model, two angle transducers are formed by the two electronic compass chips which are arranged on a circuit board and have 12bit precision and the magnets arranged on two gears respectively; the two gears are retarded through a planet gear, thereby enabling the speed ratio of the two angle transducers is 64:1; 12bit data of two electronic compasses is read out by using the singlechip, and the 12bit data of the two electronic compasses is processed and outputted outward, thereby forming a 18bit electronic coder. In order to adapt to a multi-circle working mode, the planet gear for retarding can also be added on the front part, and then the multi-circle electronic coder with low cost and high precision is formed.
Description
Technical field
The utility model relates to a kind of absolute encoder of measuring position of rotation, especially uses the electronic compass chip to detect, and carries out the rotary electric sub-encoders of data adjustment and output by single-chip microcomputer.
Background technology
The rotation absolute encoder that uses at present, be mostly optical-electricity encoder, substantially adopt 2 kinds of codings to read form: a kind of is to use laser-optical disk as medium, groove on CD, the groove of reading on CD by laser sensor identifies coding, judges position of rotation.As sensor information, shortcoming is that resolution is higher with laser-optical disk, and required diameter is larger, and the size of sensor is just larger; And be all individual pen work, when using as the need multi-turn, need externally add gear reducer.A kind of is multipole use hollow out or with the code-wheel of reflectorized material, detects position of rotation by photodiode.Because the size of diode is larger, every one-level bits of coded number can be too not high.Therefore, precision be improved and scrambler progression will be increased.And the increase of progression just requires gear manufacturing accuracy and installation accuracy to improve, and strengthens production difficulty, improves production cost.
Summary of the invention
In order to obtain high precision, encoder, the invention provides a kind of use electronic compass chip as sensor cheaply, uses single-chip microcomputer to carry out data and process, and makes the Lineside encoding unit of speed reduction unit of planet wheel.
The technical scheme that the utility model uses is: electronic compass chip and 2 magnet that are arranged on gear reducer of using 2 12 precision, form 2 angular transducers, 2 angular transducer speed ratios are 1:64, use spring by depression bar, transmission gear to be compressed, by single-chip microcomputer, the data of reading from the electronic compass chip are converted, consist of the Lineside encoding unit of 18.Count working method for adapting to more multi-turn, also can be forwardly again step planetary gear slow down, consist of low-cost, high-precision multi-turn Lineside encoding unit.
The beneficial effects of the utility model are: a kind of multi-turn of high precision cheaply absolute encoder is provided.
