Data label, and by the data structure label original sensor data in table 1.
Table 1
In an embodiment of the present invention, tag generation module can be by identifying data information or sensor phase in data packet
Information is closed, according to preset rules, label is added into data.Specifically：
Data ID is sensing data unique identifying number, can be certainly for the accurate location of CPU positioning respective sensors
It so counts, can also be realized according to information such as type, geographical locations using structured coding,
Whether data variation tag characterization single data produce variation at any time, according to data variation label, processor
Only extraction may be selected and produce the sensing data of variation, and ignore not changed sensing data, so as to reduce data
Transmission quantity accelerates Refresh Data frequency.
Whether data alarm tag characterization single data fluctuations according to data alert label, processor beyond normal range (NR)
Only extraction may be selected and produce the sensing data of unusual fluctuations, and ignore the sensing data fluctuated in normal range (NR), from
And volume of transmitted data is reduced in a wider context.When generating the alarm label, the number of triggering alarm can be flexibly set in FPGA
It is worth range.
Packet numbering label can be belonging to mark sensor data grouping, a data can according to sorting technique difference, and
Possess multiple packet labels, according to packet numbering label, processor may be selected only to extract some or certain several sensor groups
Sensing data, and ignore other grouping sensing data.
Under grouping alarm tag characterization synchronization, whether the pattern that one group of sensor values is presented is located at exceptions area
Domain alerts label according to grouping, and processor may be selected concern and the grouped data of abnormal patterns occurs, and ignore under normal mode
Grouped data.When generating the alarm label, it can flexibly be set in FPGA and generate abnormal patterns.
With continued reference to Fig. 3, method further comprises：
3) one group of register is preserved inside FPGA for setting filter condition, CPU sets filter condition by control channel,
For example, the sensor values of data variation do not occur for setting filtering, only refresh the sensor values for generating variation；
4) dynamic group packet module screens qualified sensing data composition data packet (encumbrance according to filter condition
According to ID and data content)；
5) dynamic group packet module delivers a packet to CPU processor from data channel；
6) CPU obtains sensing data, and perform corresponding task according to sensing data after parsing data packet；
7) CPU can also be according to the sensing data of acquisition and itself mission requirements, by setting filter condition with selectivity
Extraction sensing data, such as selective extraction grouping alarm data, can be in large-range monitoring grouped data abnormal conditions；Or it carries
The sensing data of a certain grouping is taken, is formed " attention window ", observes the local detail of the grouped data.
