Abstract
The invention discloses a kind of data safety subregion communication means based on network system, two independent telecommunication circuits are arranged in wireless communication terminal, communication channel is selected according to the data type of transmission, the following steps are included: S1: wireless communication terminal is communicated with host computer, receives data transfer command；S2: if the data that need to be transmitted are the continuous data of electric system, starting High Speed Serial and receive the continuous data, if the data that need to be transmitted are the creation data of electric system, start common serial ports and receives the creation data；S3: being sent to host computer by broadband transmission for continuous data, and creation data is sent to host computer by narrow band transmission.Under the premise of not changing, not influencing former wireless communication terminal installation space, working power, operational reliability, the hardware physical isolation for realizing power marketing continuous data and distribution production management data is shunted.
Description
Technical field
The present invention relates to electric network data transmission field more particularly to a kind of data safety subregion communications based on network system
Method.
Background technique
Concentrator long range wireless communication terminal is that the data that national grid concentrated collection device acquires electricity consumption realize long distance
From data relay device, abbreviation wireless communication terminal.
With being constantly progressive for society, high-end manufacturing industry, the commercially requirement to power grid high quality, high reliability are increasingly
It is more, it is higher and higher.If power grid production division cannot by effective technological means to the production run situation of grid equipment into
If row remote servicing, management, optimization, domestic high-end manufacturing industry (such as high-precision chip technology) can not just give birth at home
Processing is produced, the development of our high-end industries can be seriously hindered.Therefore, realize that " battalion is with integration " management is the certainty of power network development
Trend.
It is divided into totally five, an area, 2nd area, 3rd area, 4th area, 5th area from high to low according to electric power network data security levels
Security partitioning, continuous data of marketing answering between different security level subregion, data from distribution production management data membership
Information Security is ensured using the methods of hardware physical isolation or uni-directional physical isolation.
The type of production data of electric system include: under level-one earth leakage protective, second level earth leakage protective and three-level earth leakage protective
Electric current, voltage, active power, power factor, transformer temperature state, transformer pressure state, in on-pole switch division state
It is one or more；Overall amount of data is small, and confidentiality is high, and requirement of real-time is not high.
The continuous data of electric system specifically includes that ammeter operating status, the electricity charge, and situation of paying the fees, remaining sum prestores.It is whole
Volume data amount is big, and confidentiality is high, and requirement of real-time is relatively high.
Currently, commercial concentrator wireless communication terminal status is as follows in the market: the long range wireless communication of the first generation is whole
End, the wireless communication technique of GSM, GPRS that most of producers use；The long range wireless communication terminal of the second generation, most of factories
The wireless communication technique of 3G, 4G that family uses.Above-mentioned long range wireless communication terminal can only collect power marketing stoichiometric number
According to monitoring data needed for electricity, loss and electric-power metering that is, civilian, business, industrial user use etc. do not acquire
It forwards grid equipment creation data (data such as equipment management, operating parameter, status monitoring).
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of data safety subregion communication means based on network system, nothing
Two independent telecommunication circuits are arranged in line communication terminal, select communication channel according to the data type of transmission, comprising the following steps:
S1: wireless communication terminal is communicated with host computer, receives data transfer command；
S2: if the data that need to be transmitted are the continuous data of electric system, start High Speed Serial and receive the continuous data, if needing
The data of transmission are the creation data of electric system, then start common serial ports and receive the creation data；
S3: being sent to host computer by broadband transmission for continuous data, and creation data is sent to host computer by narrow band transmission.
Further, the method that creation data is sent are as follows: processor and narrow channel are communicated using serial ports, execute standard
AT instruction, is sent to host computer for creation data.
Further, the common serial ports uses RS485 serial ports；The broadband transmission uses 3G, 4G, 4.5G or 5G communication mark
One of standard；The narrow band transmission uses one of NB-IOT communication standard, 230M electric power private radio communication standard.
The beneficial effects of the present invention are: do not change, do not influence former wireless communication terminal installation space, working power,
Under the premise of operational reliability, the hardware physical isolation point of power marketing continuous data and distribution production management data is realized
Stream.The data isolation in different safety class region is realized by two completely self-contained long range wireless communication private networks.
Detailed description of the invention
Fig. 1 is a kind of data safety subregion communication means schematic diagram based on network system.
Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art more fully understand technical solution of the present invention
Applying example, the present invention is described in further detail.
Two independent communications are arranged in a kind of data safety subregion communication means based on network system, wireless communication terminal
Circuit selects communication channel according to the data type of transmission, comprising the following steps:
S1: wireless communication terminal is communicated with host computer, receives data transfer command；
S2: if the data that need to be transmitted are the continuous data of electric system, start High Speed Serial and receive the continuous data, if needing
The data of transmission are the creation data of electric system, then start common serial ports and receive the creation data；
S3: being sent to host computer by broadband transmission for continuous data, and creation data is sent to host computer by narrow band transmission.
Further, the method that creation data is sent are as follows: processor and narrow channel are communicated using serial ports, execute standard
AT instruction, is sent to host computer for creation data.
Further, the common serial ports uses RS485 serial ports；The broadband transmission uses 3G, 4G, 4.5G or 5G communication mark
One of standard；The narrow band transmission uses one of NB-IOT communication standard, 230M electric power private radio communication standard.
In the present embodiment, data collection steps are as follows: electric-power metering data are acquired by concentrator, are adopted by RS485 interface
Collect electric power creation data, and two kinds of data are transferred to control unit, specifically, control unit uses CortexM4 processor,
CortexM4 processor is communicated with concentrator, and carries out copy reading to creation data by RS485 interface.
Communications judgment step are as follows: processor and broadband channel are communicated using High Speed Serial, and are realized long-range logical
The management in road；Processor and narrow channel are communicated using serial ports, execute standard AT instruction；CortexM4 processor is as control
Unit judges data type processed is transmitted if data type is continuous data by broadband connections；If data type
For creation data, communication is transmitted.
