First embodiment
Fig. 3 is please referred to, Fig. 3 is the flow chart of a kind of method of downloading data message that first embodiment of the invention provides,
The method is applied to terminal device, and described method includes following steps：
Step S110：The terminal device sends the first pieces of firmware for downloading latest edition firmware to the server
Section obtains request.
Terminal device and server during normal service data interaction is carried out are led to by CoAP agreements
Letter, CoAP are the synonym of restricted application protocol (Constrained Application Protocol) and HTTP associations
It discusses similar, based on REST (Representational State Transfer) framework, provides GET, POST, PUT, DELETE
Method, but also allow for the application of Internet of Things and M2M and improve some mechanism and increase some functions.CoAP agreements are very
Compact, minimum data message can only have 4 bytes, and message structure is as shown in Figure 4.
This method is also to be made by CoAP agreements by the communication between CoAP protocol realizations terminal device and server
Downloading mode for firmware file.By combining the characteristic of CoAP agreements, resource-constrained network on the one hand can be effectively adapted to
And node, on the other hand it can simplify protocol stack.
Each data communication message that terminal device and server by CoAP agreements send in data exchange process
(i.e. business datum message) can all pass through integrality effect (optional MD5, SHA1, CRC etc.), it is ensured that accessed by this method
The integrality of firmware file, general CON-GET message structures are shown in Fig. 5.
In CON-GET message structures, ID, ID label including version number, type of message, each CoAP message are asked
Ask head and the data information of interaction etc..
When terminal device and server are carried out during business data transmission, if terminal device want to it is mounted certain
It when a firmware is upgraded, then can be asked in the carrying firmware upgrade in the business datum message sent to server, and should
It may include the information such as the current version number for having mounted firmware and the firmware identifiers in firmware upgrade request, also, this is solid
Part upgrade request may include sending together in the business datum message sent to server in terminal device, so as to reduce terminal
The occupancy of device resource.After server obtains firmware upgrade request, the latest edition of the firmware is obtained according to the firmware identifiers
This number, and when server sends business datum message to terminal device, the latest edition number of the firmware is included in the industry
It is sent together in business data message, terminal device receives the latest edition number of firmware, then by the newest of the firmware received
The current version number of version number and firmware is compared, if the current version number of the firmware is not latest edition number, it is determined that
It needs to upgrade the estimation being installed in the terminal device, i.e., into firmware pattern to be upgraded.
After terminal device enters pattern to be upgraded, terminal device is according to normal condition and server into row data communication mistake
Cheng Zhong can send to the server and obtain request for downloading the first pieces of firmware of latest edition firmware.
Step S120：The terminal device obtains the first business datum message that the server is sent.
Terminal data obtains request by being included in terminal device to server to the first pieces of firmware that server is sent
In the business datum message of transmission, server is after getting first pieces of firmware and obtaining request, to the terminal device
The first business datum message is sent, the server is included in the first business datum message according to first pieces of firmware
Obtain the first pieces of firmware that request obtains.
Terminal device obtains the first business datum message that the server is sent, so as to from the first business datum message
In get the first pieces of firmware.
Wherein, a complete firmware can be made of multiple pieces of firmware length, and pieces of firmware length is long for message
Threshold value subtracts the data length that this time interacts, such as in this terminal device and server carry out data exchange process, if
Terminal device needs to ask for 2 data to server, and the long threshold value of preset message is according to practical application network environment, in advance
State the appropriate data message length of setting on the server, in the embodiment, which refers to the first business datum message,
For example, can the long threshold value of the message be set as 5, then it is 3 to include pieces of firmware length in the first business datum message
The first pieces of firmware that first pieces of firmware, i.e. the first business datum message are data including 2 and pieces of firmware length is 3
Section.
After terminal device gets first pieces of firmware, the integrality of first pieces of firmware can be judged,
That is, in each data message that the terminal device is sent, a completeness check position can be all carried, it is ensured that accessed
The integrality of firmware file, such as detects whether first pieces of firmware has loss of data, if there is loss, judges first firmware
Segment is imperfect segment, if not losing, judges that first pieces of firmware for complete segment, has been in the first pieces of firmware
During full wafer section, terminal device can send the during service data interaction is carried out with server next time to the server
Two pieces of firmware obtain request, represent to obtain the second pieces of firmware.
Server obtains request in the second pieces of firmware for obtaining terminal device transmission, and the second business is sent to terminal device
Data message, second pieces of firmware obtain request and can also reside in terminal device into the business datum message that server is sent
It is sent, which includes the server and obtain what request obtained according to second pieces of firmware
Second pieces of firmware.
Terminal device can from server send the second business datum message in obtain the second pieces of firmware, then in order to
Ensure the integrality of pieces of firmware, also need to judge the integrality of second pieces of firmware, judge complete method and to first
The integrality judgment method of pieces of firmware is consistent, after judging the second pieces of firmware for complete segment, terminal device can continue to
Server sends third pieces of firmware and obtains request, and after getting complete latest edition firmware, terminal device can be run
The latest edition firmware is installed.
When the terminal device judges first pieces of firmware for imperfect segment, the terminal device can be to institute
It states server and sends the request for obtaining the first pieces of firmware again, is i.e. third pieces of firmware obtains request, and server is being got
After the third pieces of firmware that terminal device is sent obtains request, third business datum message, the third industry are sent to terminal device
Business data message includes the third pieces of firmware that the server obtains request acquisition according to the third pieces of firmware.
Terminal device can get third pieces of firmware from the third business datum message of acquisition, the third pieces of firmware
Section is identical with the first pieces of firmware, but can also include the first pieces of firmware, i.e. third pieces of firmware includes at least described first
Pieces of firmware, certainly, can also be only therein a bit of comprising the first pieces of firmware in the third pieces of firmware.Namely
It says, in terminal device initiates the acquisition request of third firmware again, expression also needs to reacquire the first pieces of firmware, if but taking
The business datum that business device is sent in the third business datum message of terminal device is small, and occupied space is smaller, then in third
Pieces of firmware length can be increased in pieces of firmware, if the first pieces of firmware is a, then third pieces of firmware can be a or abc
Deng.If the business datum that server is sent in the third business datum message of terminal device is big, occupied space is bigger, then
Pieces of firmware length can be reduced in third pieces of firmware, if the first pieces of firmware is abc, then third pieces of firmware can be a
Or ab etc..
In addition, server is in the first business datum message for issuing terminal device, for the ease of the complete of entire firmware
Property verification, pieces of firmware can also be numbered, such as the first pieces of firmware have the first number, the second pieces of firmware has the second volume
Number, the first pieces of firmware that server is numbered in first sent to terminal device, if terminal device judges first pieces of firmware
Section is complete segment, then the second number of the second pieces of firmware sent in server to terminal device is that the first number adds 1, i.e.,
If for the first number of the first pieces of firmware when being 1, the second number is 2, if terminal device is judging that the first pieces of firmware is not
During complete segment, then also need to retransmit the third pieces of firmware containing the first pieces of firmware, then at this time by third pieces of firmware
Third number equal to the first number of the first pieces of firmware, the first number of even the first pieces of firmware when being 1, then consolidate by third
The third number of part segment is also 1, that is to say, that number is constant, and the first pieces of firmware continues to carry and server and terminal device
The message of normal communication next time (third business datum message) in, the third business datum message format is as shown in Figure 6
CON-GET message formats.
Wherein, in the business datum message sent in server to the terminal device, such as the first business datum message and
Third business datum message, when filled in business datum message terminal device need server respond data after, the data are also
Not up to message long threshold value when, then whether have update, if being updated over, filled out in remaining space if first judging the number of pieces of firmware
Next section of pieces of firmware is filled, if as shown in fig. 7, the number of pieces of firmware does not update, the remaining firmware of upper segment return
The caching of file, redistributes the pieces of firmware of appropriate length, and fills remaining space.If when the data filling of server response
Afterwards, the long threshold value of message is had reached, then does not refill pieces of firmware, as shown in figure 8, i.e. this time of server is sent to terminal device
