摘要： An absolute position coding (1) comprises mutually parallel code tracks (11, 12). One code track (11) has a first code sequence (A) in succession, and the other code track (12) has a second code sequence (B) in succession. Within the measurement range to be determined in absolute terms, multiple first code sequences (A) are arranged in the one code track (11) and second code sequences (B) are arranged in the additional code track (12). Each of the two code sequences (A, B) comprise a sequence of code elements, which have the same dimensions in the measurement direction (X). The number of code elements within the two code sequences (A, B) is different, so that the code sequences (A, B) have different lengths (L
A , L
B ). By sampling the code tracks (11, 12) by means of a sampling unit (2), partial positions (X
A ) are obtained within the first code sequence (A), defining a unique absolute position (POS) over the measurement range in combination with the respective partial position (X
B ) within the second code sequence (B).
摘要翻译：绝对位置编码（1）包括相互平行的码轨道（11,12）。一个码道（11）连续地具有第一码序列（A），另一码轨道（12）依次具有第二码序列（B）。在绝对值确定的测量范围内，多个第一码序列（A）被布置在一个码道（11）中，第二码序列（B）被布置在附加码轨道（12）中。两个代码序列（A，B）中的每一个包括在测量方向（X）上具有相同尺寸的代码元素序列。两个代码序列（A，B）中的代码元素的数量是不同的，因此代码序列（A，B）具有不同的长度（LA，LB）。通过采样单元（2）对代码轨道（11,12）进行采样，在第一代码序列（A）内获得部分位置（XA），在组合的测量范围上定义唯一的绝对位置（POS）其中第二代码序列（B）内的相应部分位置（XB）。

摘要： An absolute position code (1) is designed as a single-track code. It consists of a plurality of code sequences (A, B) which have different lengths (L
A , L
B ) and which, when combined, absolutely encode a measurement range in an unambiguous manner. For this purpose, code elements of the plurality of code sequences (A, B) are arranged according to a predetermined sequence which forms a segment that in turn is repeatedly arranged one after the other within the measurement range. In order to be able to absolutely encode an as wide a measurement range as possible in an unambiguous manner, each of the segments comprises at least three code elements. In order to determine an unambiguous position (POS) within the measurement range of the position code (1), a decoding device (3) is provided which has a table (T
A , T
B ) for each of the two code sequences (A, B) for decoding. The absolute position (POS) is determined from the obtained partial positions (x
A , x
B ) within the plurality of code sequences (A, B).
摘要翻译：绝对位置码（1）被设计为单轨道码。它由具有不同长度（LA，LB）的多个码序列（A，B）组成，并且当组合时，以明确的方式绝对地编码测量范围。为此，多个代码序列（A，B）中的代码元素按照预定的顺序进行排列，该预定序列形成在测量范围内依次重复排列的段。为了能够以明确的方式绝对地编码尽可能宽的测量范围，每个段包括至少三个代码元素。为了确定位置码（1）的测量范围内的明确位置（POS），提供了一种解码装置（3），其具有用于两个码序列（A，B）中的每一个的表（TA，TB））进行解码。从多个代码序列（A，B）中获得的部分位置（xA，xB）确定绝对位置（POS）。

摘要： The invention relates to the standardization of angle-measuring devices. A scanning device (20) is designed in such a manner as to be suitable for scanning a first closed code (C1) and a second closed code (C2). The second code (C2) is a joined section (V) of subsequent code elements (A3 to A13) of the first code (C1). The angle-measuring device comprises a scanning device (20), the decoding device (30) of which can be operated in a first or in a second mode of operation depending on an identification (ID) which defines the codes (C1, C2) to be decoded in such a manner that they are distinct. In the first mode of operation, the first code (C1) is decoded by a decoding table (T2) having a first and a second set of values. In the second mode of operation, the section (V) of the second code (C2) which corresponds to the first code (C1) is also decoded by the first set of values of the decoding table (T2) and the new sequence of code elements of the second code (C2), which is formed at the joint (ST2) by joining the section (V) taken over from the first code (C1), is decoded by an additional small decoding table (T5) having a third set of values.
