Fig. 2 is a kind of high-level schematic functional block diagram of the device of data receiver provided in an embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples the embodiment of the present invention is described in further detail.It is understood that this
The described specific embodiment in place is used only for explaining the embodiment of the present invention, rather than the restriction to the embodiment of the present invention.In addition also
It should be noted that for the ease of description, illustrate only the part related to the embodiment of the present invention rather than entire infrastructure in accompanying drawing.
With reference to Fig. 1, Fig. 1 is a kind of schematic flow sheet of the method for data receiver provided in an embodiment of the present invention.
As shown in figure 1, the method for described data receiver includes:
Step 101, intelligent object is progressively redirected formula scanning according to preset order and time interval, and obtains message number
According to described message data is the message data that mobile terminal is transmitted according to default subpackage mode;
Preferably, described intelligent object is progressively redirected formula scanning according to preset order and time interval, including:
Described intelligent object has to stop on the channel of message in scanning presets the very first time;
If described intelligent object receives next message within the described very first time, increase described intelligent object and stop
Time on the described channel having message;
If not continuing to receive message within the increased time and the time of described increase exceeding preset time threshold, according to
Preset order and time interval are progressively redirected formula scanning.
Specifically, channel does not lock, and is circulating always, when receiving a multi-cast message data, stops, works as reception
Then increase the channel locks time of staying to second, by that analogy.When over-time enters scan channel, receiving data again.
The capacity of resisting disturbance of wifi module so can be greatly improved.
Preferably, described intelligent object obtains message data, including:
Described intelligent object judges it is the message whether described message data is same mobile terminal according to source MAC
Data;
If described message data is the message data of same mobile terminal, described intelligent object obtains same movement
The message data that terminal sends.
Specifically, same source is possible to send a lot of other multicast message forms.Intelligent object can record and connect first
By the source mac address of the mobile terminal of message, then intelligent object locks the message that source address can exclude other-end.
Preferably, described intelligent object obtains the message data that same mobile terminal sends, including:
Described intelligent object judges whether the inclusion length of the message data that same mobile terminal sends is identical;If described
Inclusion length is identical, then described intelligent terminal obtains the message data of the same inclusion length that same mobile terminal sends.
Specifically, in the case of intelligent object locking source mac address, the mark of oneself is added to each bag sending,
And the length of each inclusion in same message is the same, and according to certain alignment thereof.As entered according to 16
System alignment, does not fill full replacing with 0.Just flag bit can be taken when receiving first message, each be received simultaneously
Packet length measure, find with upper one as grow just receives in the middle of queue.It is ranked up, deciphers when acceptance is over,
Obtain initial data.
Preferably, described intelligent object obtains message data, including:
If described intelligent terminal receives the message that two different mobile terminals send on same lock channel,
Described intelligent object retains the message that first mobile terminal sends sequentially in time, and abandons second mobile terminal transmission
Message.
Specifically, if the mobile terminal of more than two transmissions is different message, intelligent object is connected to first from others
Interference message, by first message receiving, compares (when receiving a message, we just record former mac address), when
When second message comes, compare and whether the mac address of first message is same, be not to abandon.
Step 102, described intelligent terminal is according to the mark described report of restructuring of each bag carrying in described message data
Civilian data, and described message data is decoded according to the encryption factor in described message data.
The embodiment of the present invention provides a kind of method of data receiver, and intelligent object is carried out according to preset order and time interval
Progressively redirect formula scanning, and obtain message data, described message data is transmitted according to default subpackage mode for mobile terminal
Message data;Described intelligent terminal is according to the mark described message number of restructuring of each bag carrying in described message data
According to, and described message data is decoded according to the encryption factor in described message data.Described intelligent object pattern in order
Progressively redirected, until there being the message meeting, started lock channel, this scan channel mode greatly improves channel and finds
Time, increase the time connecting network.
With reference to Fig. 2, Fig. 2 is a kind of high-level schematic functional block diagram of the device of data receiver provided in an embodiment of the present invention.

Wherein, described recombination module 203, carries out order weight for receiving complete message according to the sequence number of each message
Group.Described deciphering module 204, for the encryption factor according to message, deciphers the password of encryption, then the key handle taking deciphering first
Message becomes in plain text.Wherein, described encryption factor is to be generated according to " transmission " time by mobile terminal and then pass through message
It is sent to intelligent object, thus all the time all different.
Preferably, described scan module 201, specifically for:
Have on the channel of message in scanning and stop the default very first time;
If described intelligent object receives next message within the described very first time, increase described intelligent object and stop
Time on the described channel having message;
If not continuing to receive message within the increased time and the time of described increase exceeding preset time threshold, according to
Preset order and time interval are progressively redirected formula scanning.
Preferably, described acquisition module 202, specifically for:
Judge it is the message data whether described message data is same mobile terminal according to source MAC;
If described message data is the message data of same mobile terminal, obtain the report that same mobile terminal sends
Civilian data.
Preferably, described acquisition module 202, also particularly useful for:
Judge whether the inclusion length of the message data that same mobile terminal sends is identical;If described inclusion length phase
Same, then obtain the message data of the same inclusion length that same mobile terminal sends.
