Embodiment
The tactics data message form of the tactics data message standard code of current my army is all variable message format.Variable message format adapts to the thought of " sending as required ", according to the needs assembling of certain transmission and transmission message, its message content has adopted the structure of variable-length, concrete length determines by the information content, adopted simultaneously option, can duplicate keys, the technology such as data element dictionary shortens message length as far as possible.The field and the Optional Field (or field groups) that are mainly reflected in necessary appearance that variable message format message length is variable.In variable message format message, whether certain field or field groups there is (being included in message), by FPI (Field Presence Indicator, there is indicator in field), FRI (Field Recurrence Indicator, field repetition indicator), GPI (Group Presence Indicator, there is indicator in group) and 4 indicators of GRI (Group Recurrence Indicator, group repeat indicator) determine.Above-mentioned 4 indicators only account for 1 bit in actual message.FPI and GPI are that the corresponding field of 1 expression and group occur in message, otherwise this field or group do not occur; FRI and GRI represent respectively whether field or group repeat, and are mainly used in identifying the data of a plurality of same types, and FRI and GRI are still identical field or field groups after 1 expression.
When variable message format message data is encoded in final physical, each field represents by binary eight hytes, and each message is encoded separately.The least significant bit (LSB) of each field is placed in eight hytes still on uncoded least significant bit (LSB), and the next least significant bit (LSB) of field is arranged in the eight hyte next ones still on uncoded least significant bit (LSB).Before all bits of encoded of field complete, if there are eight hytes to be filled, by continuing remaining bit to carry out the coding of next eight hytes, from first field and eight hytes, constantly repeat, until the coding of all fields is completed.When coding, data field can be divided into binary data field and character data field, and binary data field is represented by one or more bits, the actual physics numerical value of its this field of value representation.Character data field is comprised of the character of some 8 bits, value (00000000) for the end mark of character field
2represent.
On the other hand, variable message format message also shortens message length by data element dictionary as far as possible.Data element dictionary is for being converted to corresponding logical value by the physical values of message field (MFLD).Data element dictionary comprises three basic forms of it: enumeration type, numeric type and character string type.Data of enumeration type element dictionary is converted to enumeration type in logic by binary physical values, as: by (00) of physical values
2corresponding " reconnaissance plane ", by (01) of physical values
2corresponding " bomber ", by (10) of physical values
2corresponding " fighter plane ", by (11) of physical values
2corresponding " early warning plane ".Numeric type data element dictionary is converted to integer or floating type in logic by binary physical values, as: by (00) of physical values
2correspondence 0.01, by (01) of physical values
2correspondence 0.02, by (10) of physical values
2correspondence 0.03, by (11) of physical values
2corresponding 0.04.Numeric type data dictionary, when having stipulated the corresponding numeric type logical value of scale-of-two physical values, has in fact also been stipulated the legal range of numeric type logical value.Character string data element dictionary stipulates that the physical values of current field is character data field, has also stipulated the maximum length of character string.
For the These characteristics of tactics data message, the invention provides a kind of tactics data message analogy method, can realize the automatic generation of tactics data message simulator program, promote efficiency and automaticity that simulation generates tactics data message.Below in conjunction with drawings and the specific embodiments, the present invention will be further described in detail.
Fig. 1 is the overall procedure schematic diagram of tactics data message analogy method of the present invention, as shown in Figure 1, comprises the following steps:

Step 3, according to inner structure, quote degree of depth order from big to small, generate the source code of tactics data message organization definition, encoding and decoding, editing interface and data element dictionary conversion;
Step 4, the compilation of source code of utilizing tactics data message organization definition, encoding and decoding, editing interface and data element dictionary to change obtain tactics data message simulator program;
Step 5, utilize tactics data message simulator program simulation generate tactics data message and send to actual equipment software.
Step 1.1, tactics data message structure descriptor is divided into a series of data item, data item is divided into elementary item and group item, and elementary item can not be divided again, and group item is formed by other data item combinations;
Elementary field in elementary item corresponding variable message format message, the group in group item corresponding variable message format message.
Step 1.2, data element dictionary information is divided into enumeration type, character string type and value type;
Step 1.3, according to tactics data message standard compliation elementary item information, group item information, enumeration type data element dictionary information, character string type data element dictionary information and value type data element dictionary information;
First by the information of all elementary items of interface typing, comprise the English name, Chinese, description, type, reference identification (unique), data length (bitwise) of elementary item etc.; Secondly, the subitem comprising by the mode editor's group item pulling and the specifying information of each subitem, each subitem information comprises: Chinese, name variable (producing variable name while defining for generating structure), description, elementary item reference identification, can multiplicity, optional sign etc. whether; Finally, by all data element dictionary information of interface typing, enumeration type data element dictionary information comprises: elementary item reference identification, physical values, logical value etc., character string type data element dictionary information comprises elementary item reference identification, string length etc., and value type data element dictionary information comprises: elementary item reference identification, sequence number, physics initial value, physics stop value, logic initial value, logic stop value, logical value type (integer or floating type) etc.
Step 1.4, the elementary item information editting, group item information, enumeration type data element dictionary information, character string type data element dictionary information and value type data element dictionary information are left in database table respectively.
