Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

The embodiment of the invention discloses a kind of method for packing of Internet ICD, accompanying drawing 1 is referred to, methods described is specifically wrapped Include following steps：

S101：When encapsulation instruction is received, at least one is matched with the encapsulation corresponding logic parameter of instruction；

Specifically, the encapsulation instruction involved by the embodiment of the present invention can be according to source device control in avionics system The purpose equipment processed message of required transmission and instruction for generating when carrying out a certain operation, instruction of such as taking off, landing instruction, slowing down refers to Order etc..

After source device parses the message to be transmitted from encapsulation instruction, source device is to the transmission message for convenience Carry out the treatment operation of correlation, it is possible to use logic parameter defines the physical significance of the message, therefore in avionics system After middle source device receives encapsulation instruction, first can go out corresponding logic parameter according to the encapsulation instructions match, as follow-up envelope Basic data needed for dress Internet ICD.Wherein, the number of the logic parameter corresponding to an encapsulation instruction can be one, Can also be multiple.

S102：Calculate the required length of field value of each logic parameter；

Specifically, because logic parameter cannot be transmitted directly in Internet, it is therefore desirable to which logic parameter is stored in into correspondence Data block be transmitted again, and, it is necessary to first calculate the required length of field value of logic parameter itself before data block is stored in, Prevent from being stored in failure.

S103：The matching bus links for pre-building corresponding with logic parameter each described；

Specifically, the transmission due to carrying out data between source device and purpose equipment communicates mainly being built by between equipment Vertical virtual transmission link, therefore after one or more logic parameters are matched, in addition it is also necessary to for each logic parameter, matching Go out corresponding bus links, wherein, bus links corresponding with logic parameter are to be set up in source device in advance, and point Be not mapped to purpose equipment, bus links can including 1553B, ARINC429, ARINC422, Ethernet etc. communication link, and The attribute that each bus links has includes：Source device, purpose equipment, refresh cycle, maximum delay, transport-type etc.. It is illustrated by taking Fig. 2 as an example, pre-builds two bus links in source device, respectively 1553A and 1553B, wherein, Link 1553A connects equipment Device1, Device2, Device3 and Device4 respectively, and link 1553B connects equipment respectively Device3 and Device4, if using equipment Device1 as source device, equipment Device2, then can be by even used as purpose equipment Equipment Device1 is met with the bus links 1553A of Device2 as corresponding bus links, so as to follow-up source device Device1 Message is transmitted to purpose equipment Device2.One bus links can correspond to a logic parameter, it is also possible to while correspondence is multiple Logic parameter.

The interface of each bus links is held and remote terminal comprising bus control unit end (BUS CONTROLER, BC) (REMOTE TERMINAL, RT), still illustrates, the interface that bus links 1553A is connected with equipment Device1 by taking Fig. 2 as an example Can be that the interface that BC ends, then equipment Device2, Device3 and Device4 are connected with bus links 1553A can only be RT ends. When by bus links 1553A transmission data block messages, the transmission direction of data block message can include：RT is sent to from BC ends End, is sent to BC ends and is sent to RT ends from RT ends from RT ends.Wherein, RT ends can set subaddressing.

S104：Whether each described bus links is judged comprising the first data block, signal in first data block The length value of white space is more than or equal to the required length of field value of logic parameter corresponding with the bus links, if comprising, S105 is performed, if not including, S106 is performed；

Specifically, each bus links can have respective data block, for storing transmission data, and each data Block possesses respective signal again, and signal only within the data block is when having white space, can be to being deposited in the data block Enter a number of data, therefore after the required length of field value for calculating each logic parameter, in addition it is also necessary to for each Whether bus links corresponding to logic parameter, judge there is length value more than or equal to right in each data block contained by it respectively Answer the white space of the signal of the required length of field value of logic parameter such that it is able to effectively prevent the sky of the signal in factor data block The problem of data storage failure caused by white region deficiency.

S105：The logic parameter corresponding with the bus links is stored in the sky of signal in first data block White region, as the numeric field data of first data block；

Specifically, there being required domain of the length value more than or equal to counterlogic parameter in the data block contained by bus links During the white space of the signal of length value, directly corresponding logic parameter can be stored in the white space of its signal, as The numeric field data of the data block, is easy to subsequently be transmitted operation.

For example, equipment Device1 is used as source device, used as purpose equipment, para1 is used as logic for equipment Device2 Parameter, the 1553A bus links that A/D1D2/00 is matched as correspondence para1, for the required domain of logic parameter para1 Length value is this condition of 8bit, and source device Device1 can successively be determined from bus links A/D1D2/00 and be met the condition The first data block A/D1D2/00-01, the signal 0signal_155300-/D1 of first data block and the blank of the signal Region bit0~bit7, logic parameter para1 is directly stored in the signal of the first data block A/D1D2/00-01 afterwards In the white space bit0~bit7 of 0signal_155300-/D1.

S106：The second data block is set up, and performs S107；

Specifically, the white space length value of the signal having in the data block contained by bus links is less than counterlogic During the required length of field value of parameter, then a newly-built data block in the bus links is needed, for storing its corresponding logic Parameter.Wherein, when being named to newly-built data block, can be based on contained by the relevant information and bus links of bus links Data block puts in order to name, such as A/D1D2/00-01, and A is the relevant information of bus links, and 00-01 is contained by bus links Data block puts in order.

S107：The logic parameter corresponding with the bus links is stored in the sky of signal in second data block White region, as the numeric field data of second data block；

Specifically, because the second data block is the sky containing enough signals in newly-built data block, therefore the data block White region, for depositing corresponding logic parameter.

In a kind of method for packing of Internet ICD disclosed in the embodiment of the present invention, by from the bus chain for pre-building Bus links corresponding with each logic parameter are matched in road, personnel can be reduced in Internet ICD encapsulation process Workload, to reach the purpose of time spent by reduction encapsulation process, afterwards according to the institute of each logic parameter for calculating Length of field value is needed, judges whether the length value of the white space of the signal of contained data block in each bus links is more than or equal to The required length of field value of counterlogic parameter, and the length value of the white space in the signal of data block is more than or equal to logic parameter Required length of field value when, using the data block as the first data block, for directly storing logic corresponding with the bus links Parameter, so that logic parameter is sent to corresponding purpose equipment by source device using first data block by network, is judging In bus links do not exist the first data block when, then directly newly-built second data block, for preserve with the bus links pair The logic parameter answered, it is seen then that the relevant information based on bus links, is automatically saved in logic parameter correspondence and meets logic parameter Required length of field value data block in, can further reduce in encapsulation process person works amount, Internet is improved indirectly The operating efficiency of ICD encapsulation.
