When the parameter field to drilling guidance supplemental characteristic packet is delimited, interleave frequently with fixed data length of field or domain
Enter the method for special separator.The former is to determine boundary in advance for the regular length of each parameter setting, the disadvantage is that can not
Corresponding data field length is adjusted according to the practical value of parameter, and the redundancy in data packet space is be easy to cause to waste；The latter is logical
It crosses and is inserted into spcial character between each data field to determine bound of parameter, the length-flexible of each data field can be made variable, still
The boundary character of insertion occupies a large amount of data transmission space, inefficiency.
Using array data field to delimit method is exactly with the value of " data field demarcation " field in data packet come to be each
Parameters data field determines boundary.It is as follows to delimit rule: when 1. generating drilling guidance supplemental characteristic packet, according to when time each parameter field
Physical length, which calculates, obtains the value that data field delimits field, and by the metric expression digit of each thresholding, (negative sign and decimal point are each
It Zhan Yiwei) is combined to obtain.2. ground is split using data packet, successively determined according to the value that data field delimits field
The boundary of each data field, extracting parameter.
Data field delimits the length of first expression package number of field, value 0,1 and 2.For example, data field is fixed
The value on boundary is 3896, shows that the package number length of this transmission is 3, includes 3 kinds of parameters, and the data length of parameter 1 is 8,
The data length of parameter 2 is 9, and the data length of parameter 3 is 6.
Compared with fixed data length of field is delimited, the array data field that this patent proposes is delimited method and is not needed in advance
For each parameter setting regular length, corresponding data field size can be adjusted in real time according to the practical value of parameter, it will not
The redundancy in data packet space is caused to waste.Compared with being inserted into special separator between domain and delimiting, this method is not necessarily to interleaving in each domain
Enter spcial character and determine boundary, saves a large amount of data packet space expense.Therefore, array data field is delimited method and is improved
The data packet that drilling guidance parameter passes down delimits method, effectively improves the efficiency of transmission of system.
Package number is the data packet for determining concrete type, and different numbers represents in data packet with different
It parameter combination form and puts in order.Actual demand according to current drilling technology to guiding parameter, user can be with self-defining
The format of data packet, i.e. staff can be configured by the measuring instrument that surface computer system goes into the well to preparation.?
When defining data packet format, need to consider the factors such as the degree of correlation, change frequency and the guiding control purpose of parameter, then to parameter
Flexible assembled arrangement is carried out, unique number finally is carried out to the data packet being ranked.
Data packet is numbered using 2 ten's digits, the range of number is 0-99, i.e., at most can customize 100
Kind data packet format.The high data packet of frequency of use indicates that the low data packet of frequency of use is indicated with 2 bit numbers with 1 bit number,
Frequency of use it is highest number be 0, in this way can further compressed data packets length.Package number technology can make with brill
Measuring system customized data packet format as needed increases system compared with the fixed data packet of traditional type
Flexibility；Reserved package number provides extension mechanism for measurement-while-drilling system, when there is more downhole parameters to need to pass
When defeated, which enables a system to define new data packet format, to meet the needs that drilling guidance parameter passes down.It is specific to bore
