The signal sources for this case are: meter measurement readings (IN digital), meter operating status readings (485 data).
The first step is as follows: selecting a channel needing to process a data source on a rule configuration and management platform through an interface: the IN digital channel + 485 channel is selected and input as the data source channel.
The second step is that: selecting a data destination channel to be forwarded through an interface on a 'rule configuration and management desk': and an IN digital channel is selected to correspond to a 4G LET private network and an Ethernet LAN3 port for simultaneous forwarding, and a 485 channel is selected to correspond to a 4G LET public network for forwarding.

{"command":"setSlotChannelMapping",
"dat": {
"Mapping":{
"slotIN":{"slotLTE4GZ":"on", "LAN3":"on"},
"slot485":{"slotLTE4G":"on"}
}
}
}

1) Opening the IN channel: portEnable (digitIN, 0);
2) Opening a 485 channel: portEnable (digit 485, 0);
3) Opening a 4G LTE private network channel: portEnable (LTE 4GZ, 0);
4) Opening a 4G LTE public network channel: portEnable (LTE 4G, 0);
5) Open LAN3 tunnel: portEnable (LAN 3, 0);

The first step is as follows: selecting the data source channel and port needing to be processed on a rule configuration and management platform through an interface: the ethernet LAN1 channel + port number 10000 is selected and input as a data source channel.
The second step is that: selecting a data destination channel to be forwarded through an interface on a 'rule configuration and management desk': selecting a 4G LET private network, inputting a forwarding port number 9100, selecting an Ethernet LAN3 port, and inputting the forwarding port number 9100.

"dat": {
"Mapping":{
" LAN1":{ "port": 10000 , "slotLTE4GZ": 9100, "LAN3": 9100}
}
}
}

1) Open LAN1 channel + port: portEnable (LAN 1, 10000);
2) Opening a 4G LTE private network channel + port: portEnable (LTE 4GZ, 9100);
3) Open LAN3 channel + port: portEnable (LAN 3, 9100);
4) Enabling the switching module to perform data forwarding: swGO (cfgData);
the instruction sequence enables the corresponding hardware equipment, acquires data from the source data port, converts the data format of the source data into an agreed common data frame format, and sends the agreed common data frame format to the data buffer area of the destination port. Thus "ethernet LAN1:10000 "of video data are sent to both the" 4G LET private network and the ethernet LAN3:9100 "data buffer; while the data buffers of the other channels are empty.
The fifth step: data egress port: and the 4G LTE private network, the public network and the Ethernet LAN3 port acquire data from respective data buffer areas and forward the data through own sending channels. When the data packet is sent, the data transmission session established with the terminal is bound to the 9100 port of the destination channel, so that the purpose of forwarding to the specific port of the specific channel is achieved.
And 5, completing forwarding of the channel data according to the configuration requirement.
Example 3 packet type exchange forwarding data handling case.
The signal sources for this case are: the meter parameter data (input from an Ethernet LAN1 port), wherein a plurality of byte working state parameters (0 xbd,0xbd as a starting mark frame, 0xef as an ending mark frame) are independently transmitted through a Beidou data channel, and other operating data are transmitted through a 4G LTE public network.
The first step is as follows: selecting the data source channel and port needing to be processed on a rule configuration and management platform through an interface: the ethernet LAN1 channel + start marker frame + end marker frame is selected and input as data source channel configuration data.
The second step: selecting a data destination channel to be forwarded through an interface on a 'rule configuration and management desk': selecting an option of 'identification frame' and inputting identification frame data; and selecting a Beidou channel, inputting on to represent that only the channel is used for forwarding without port forwarding. And selecting a 4G LET public network, and inputting on to represent that channel forwarding is only carried out and no port forwarding is carried out.
The third step: the 'rule configuration and management desk' produces setSlotFrameMapping command interface messages according to the forwarding rule settings of the first step and the second step:
{"command":"setSlotFrameMapping",
"dat": {
"Mapping":{
"LAN1":{ "frameStart": 189 , "frameEnd": 239 , "slotBD": "on"},
"LAN1":{ "frameStart": 0 , "frameEnd": 0 , "slot4GZ": "on"}
}
}
}
note that: in the JSON data of the example, 189 is a decimal representation of 0xdb, and 239 is a decimal representation of 0 xef.
The fourth step: the rule configuration and management platform transmits the rule command interface message to the multi-channel data link equipment subsystem, a rule engine of the equipment subsystem acquires rule configuration data, analyzes the configuration data in the third step to form an equipment operation instruction sequence, and calls an internal interface function to drive hardware to act:
5) Open LAN1 tunnel: portEnable (LAN 1, 0);
6) Opening a 4G LTE private network channel: portEnable (LTE 4GZ, 0);
7) Opening a Beidou channel: portEnable (BD, 0);
8) Enabling the switching module to perform data forwarding: swGO (cfgData);
the instruction sequence enables the corresponding hardware equipment, acquires data from the source data port, converts the data format of the source data into an agreed common data frame format, and sends the agreed common data frame format to the data buffer area of the destination port.
Thus, the specific parameter data (0 xbd,0xbd as the start marker frame, 0xef as the end marker frame) of "ethernet LAN1" that the user desires to reach is sent to the data buffer of "BD channel", and the other data is sent to the data buffer of "4G LTE private network"; while the data buffers of the other channels are empty.
The fifth step: data egress port: and the BD channel and the 4G LTE private network acquire data from respective data buffer areas and forward the data through own sending channels.
After the above 5 steps, the channel data is forwarded according to the configuration requirement.
Example 4 a mixed configuration exchange forwarding data handling case.
If the user has the requirement of channel, port or frame data mixing, exchanging and forwarding, the system generates a plurality of corresponding configuration instructions according to the specific requirement of the user and the mode demonstrated by the case and transmits the configuration instructions to the equipment subsystem for processing. Meanwhile, the configuration subsystem checks whether the mixed configuration conflicts before transmitting the configuration data, if so, the mixed configuration is interrupted and the user is prompted, and the mixed case does not specifically state the implementation process.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
