Description
Technical field
The present invention relates to a kind of data transmission method without fixed public network IP based on wireless data transmission terminal, belong to
SCADA system monitoring technical field.
Background technology
When data acquisition and supervisor control（SCADA）Monitoring device installation in the wild and with master station communication machine away from
From farther out when, to realize the immediate data transmission of monitoring device and master station communication machine, generally have data radio station, GSM message,
The communication modes such as GPRS, satellite short message.
Data radio station is limited by transmission range, and the influence that antenna type, antenna height and environment are adjusted the distance is very big, in nothing
Transmission range is usually no more than 30km in the case of blocking.GSM message presses number of data charging, maximum per data to support 140
Individual byte, and data delay is very big, typically only apply data volume seldom, data reliability requirement is than in relatively low system.
Satellite short-message fee is higher, is no more than 280 bytes per data, only can just make in the area without mobile network at present
With, or in the weaker area of mobile network signals as an alternate channel in system.With the continuous hair of mobile network
Exhibition, GPRS etc. are wirelessly transferred because with making full use of, existing network, resource utilization are high, can keep online all the time, logical
The features such as communication distance does not limit, transmission rate is high, rate are reasonable, has obtained good popularization in SCADA system.
When monitoring device wireless terminal is connected into network, meeting dynamic access needs to know to an IP address, now monitoring device
The IP address of road master station communication machine could be communicated.
It is as follows that more commonly used at present two kinds solve method：
1）User handles internet special line and can provide one or more and fix IP, prison in one internet special line of main website application
Survey device wireless terminal and set the IP address of master station communication machine and corresponding port numbers, be connected into after network and carry out network with main website
Communication.
2）Monitoring device SIM card opens fixed IP address of internal network business, and each wireless terminal is connected into the IP obtained during network
Address is all fixed, and monitoring device and master station communication machine are previously stored with the IP address of other side, and monitoring device can actively be sent out
Master station communication machine is transmitted data to, or main website obtains the data of monitoring device by polling mode.
In general user does not open internet private line service, and internet special line is more much higher than general network rate, especially
It is in the more nervous area of some fixed ip address resources, uses the construction cost and operation cost of the SCADA system of special line
It is relative much higher without using the system of special line.
In most cases, also do not possess practicality using the SIM card of binding fixed ip address.Domestic consumer may only
The SIM card for opening general service is handled in business hall, it is unfixed that this SIM card is connected into the IP address obtained behind internet every time
's.Only enterprise customer can just apply for binding the business of fixed ip address SIM card, and the IP address of acquisition is in fixed movement
Net, with main website IP in same LAN, but use the SIM card of binding fixed ip address higher than common SIM cards expense.
The content of the invention
The present invention proposes a kind of side without data transfer under the conditions of fixed public network IP based on wireless data transmission terminal
Method, it is possible to achieve a little to the data transfer of any and point to multi--point, solve field SCADA systems with relatively low cost
