Embodiment Construction

[0033] In traditional field SCADA systems, the monitoring device communicates directly with the main station communicator. When a large amount of data needs to be transmitted between the monitoring device and the main station communicator, traditional transmission means such as ultrashort wave, short message, satellite, etc. usually cannot meet the requirements. GPRS or other channels similar to general packet services are generally preferred due to low transmission costs and large channel capacity, but this type of channel requires the master station of the system to have an Internet dedicated line and a fixed IP address, and opening the Internet dedicated line and fixed IP address services will greatly increase Construction cost and operating cost of SCADA system.

[0034] The data transmission method without fixed public network IP based on the wireless data transmission terminal provided by the present invention comprises the following steps:

Abstract

The invention discloses a data transmission method based on a wireless data transmission terminal without a fixed public network IP. By applying for a network cloud platform data server on the network, only the ID number of the other party needs to be set for data transmission. It is not necessary to know the IP address, and it is suitable for the situation without a fixed public network. The present invention uses a monitoring device to connect a wireless data transmission terminal, and sets a unique ID number for the master station communication machine and the wireless data transmission terminal connected to each monitoring device. Realized point-to-point and point-to-multipoint data transmission. The invention not only realizes the data transmission between the monitoring device and the central station system without a public network IP address, but also greatly reduces the construction cost and operation cost of the SCADA system because the cost of renting a network cloud platform server is very low.

Description

technical field [0001] The invention relates to a data transmission method without a fixed public network IP based on a wireless data transmission terminal, and belongs to the technical field of SCADA system monitoring. Background technique [0002] When the monitoring device of the data acquisition and supervisory control system (SCADA) is installed in the field and is far away from the master station communicator, to realize direct data transmission between the monitoring device and the master station communicator, there are usually data transmission stations, GSM SMS, GPRS , satellite SMS and other communication methods. [0003] The data transmission station is limited by the transmission distance, and the antenna type, antenna height and environment have a great influence on the distance. The transmission distance generally does not exceed 30km without occlusion. GSM SMS is charged according to the number of data pieces. Each piece of data supports a maximum of 140 byt...
