According to；
Data transmission unit, for by the FPDP of the Second Type data is activation to the human-computer interface device；And
Data resolution unit, for the first kind data in the Second Type data are parsed, and the data
The first kind data for parsing are write transmitting element the real time data library unit in the human-computer interface device.
7. communicator according to claim 6, it is characterised in that in the communicator,
The Date Conversion Unit is additionally operable to first kind number is obtained from the real time data library unit of the human-computer interface device
According to, and that the first kind data and target MAC (Media Access Control) address, source MAC are packaged into into that Ethernet is capable of identify that together
Two categorical datas；
The data transmission unit can also be according to the target MAC (Media Access Control) address, source MAC address information, by the Second Type number
According to transmission to the controller based on FPGA.
8. communicator according to claim 7, it is characterised in that the Date Conversion Unit will be with same timestamp
The first kind data, break into a bag data, be then packaged into ether together with the target MAC (Media Access Control) address, source MAC
In the Second Type data that net is capable of identify that.
9. communicator according to claim 7, it is characterised in that the communicator also includes diagnosis unit, described
Diagnosis unit is used to judge whether have during the controller and the human-computer interface device are communicated therebetween
Network failure；Wherein, in a scheduled duration after side sends data, when on the other hand not receiving data, judge communication network
In network failure state.
10. communicator according to claim 6, it is characterised in that the Date Conversion Unit will according to NNet agreements
The first kind data are converted to the data of Second Type, and the data length of the Second Type is fixed；And institute
State the data that data transmission unit sends the Second Type according to fixed time interval.
11. a kind of I＆C systems, it is characterised in that the I＆C system includes：Based on the controller of FPGA, based on operating system
Human-computer interface device, and the I＆C system communicator such as claim 6-10 as described in any one, the communication dress
Put so that can communicate between the controller and the human-computer interface device.
