Stating feature can also use other modes to realize.
Fig. 2 is the broadcast communication flow chart of the broadcast data communication system of the present invention.As shown in Figure 2：
Step 201, data sending device 100 control remote data transceiver module 101 to build by the first microcontroller 103
The vertical connection with background server.Broadcast data is sent to data in a wired or wireless fashion and sends dress by background server 200
100 are put, the remote data transceiver module 101 of data sending device 100 receives the broadcast data from background server 200,
The broadcast data is further stored in broadcast data memory 104.
Step 202, data sending device 100 are read by the first microcontroller 103 is stored in broadcast data memory 104
In data message.
Step 203, the data sending device 100 are by its broadcast data sending module 105 in the synchronization pre-set
RF spot sends synchronization message.
The synchronization message as shown in figure 3, the synchronization message by message direction field, message type field, message-length
Field, message data field, message check field composition.Wherein, included in message data field for a random data.Specifically
When sending the synchronization message and broadcast data, the transmission means of packet, now described data sending device 100 can be used
The first microcontroller 103 by synchronization message, broadcast data carry out subpackage, data class type-word is added to the packet of fractionation
Section, last bag identification field, package identification field, composition data bag.The data sending device 100 passes the packet of composition
Broadcast data sending module 105 is given, broadcast data sending module is carried out broadcast data by broadcast data transmitting antenna 106
Transmitting.
The random data that step 204, the first microcontroller 103 of data sending device 100 carry to synchronization message is carried out
Irreversible transformation, send frequency with the data of the corresponding generation transmitting broadcast data of transformation results and broadcast data sends address.
Meanwhile the second microcontroller of data sink 300 enters to receiving the random data included in synchronization message
Row transmitting terminal identical irreversible transformation, obtain above-mentioned data with transformation results and send frequency and broadcast data transmission address.
Step 205, data sending device 100 are sent in broadcast data by obtained data transmission frequency and sent on address
The broadcast data, data sink correspondingly send frequency in the data and connect from broadcast data address progress broadcast data
Receive.

It is not that step 203 sends synchronization message and is divided into the progress of two steps, including：
Step 203a, data sending device 100 is sent same comprising random data in the first synchronous frequency pre-set
Walk message；
Step 203b, data sending device 100 is sent comprising identical random again in the second synchronous frequency pre-set
The synchronization message of data.
Thus synchronizing information is sent in different synchronous frequencies, it is ensured that some in poor shape in a frequency reception
Reception device can also receive synchronization message.
Another embodiment of the invention is that synchronizing information is sent twice or repeatedly in the progress of same frequency point.Thus may be used
Certain time delay is sent to give broadcast data, so as to ensure that the slower data sink of processing speed can ensure to broadcast
The reception of data.
Alternatively, the present invention can also be in synchronization message without using random data, and is embedded in directly in synchronization message
Send frequency and destination address for broadcast data, thus, without carried out at data receiver 300 it is above-mentioned can not inversion
Change, broadcast data transmission frequency and destination address can be obtained by directly reading the information in synchronization message.
Meanwhile it is only mode used in the present embodiment that the broadcast data, which sends frequency, the transmission channel of other replacements
It is used equally for substituting the manner, such as uses frequency range/logic channel/channel etc..
Preferably, after the data sink 300 receives broadcast data, the broadcast data further got is carried out
MAC（Message Authentication Codes）Computing, MAC is deposited in data with receiving（Message
Authentication Codes）The field of operation values is compared, if identical, then it is assumed that and the data are legal data,
If it is different, then think that the data are illegal.
It is preferred that the data sink 300 starts timing when receiving and starting, timeslice T is interior according to this
The broadcast data bar number that receives and the total number no more than the broadcast data of setting display is shown.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
