End.
Background technique
Petroleum industry collects the state of each sensor using RTU, so to realize the monitoring to oil field shaft mouth state at present
RTU is connected on the internal network in oil field by the network interface of oneself afterwards, this network is all the address using IPV4 at present,
The addressing of address that RTU and data acquisition server pass through IPV4.It is assisted between server and RTU by Modbus Over TCP/IP
View realizes data communication.Each operating parameter of well head is transmitted in each server.And because position is different, wellhead equipment
Realize that the mode of networking is varied.
Currently in order to realizing oil well RTU networking, for wired mode, directly pass through switch port and RTU network interface connection；
It is connect using wireless client with the AP of the wifi near oil well when wireless wifi connection；When using 3G the or 4G communication technology, again
It can be communicated using the router and mobile big tower of 3G or 4G, data communication is realized using mobile operator's Virtual Private Network.On
It states these equipment used in connection type and all only supports IPV4 at present, need to carry out overall network detailed division and turn
It changes, data could be passed.
The network in current all oil fields uses IPV4 technology, because of the shortage of address, can only use " private network " address, also
It is to say that the wellhead equipment in each oil field can only first form one " private network ", it then could be data set by multiple network conversion
In arrive corporate HQ, and the equipment that well head cannot be directly accessed in general headquarters, it is therefore desirable to a network protocol switch endpoint is realized
General headquarters directly access wellhead equipment.
