Embodiment 1

1 and 2, for an embodiment of the present invention, a method for collecting distributed heat network and photovoltaic data is provided, including:

S1: collect the first data through the external network module 100, and transmit the first data to the network connection module 200; the specific process: collect the first data through the external network module 100, and collect the interface client program 202 in the network connection module 200 (supporting Multi-protocol interface) calls the interface driver 201 (this driver uses the modbus-tcp protocol) to initiate a connection request to the external network module 100 , and transmits the first data to the network connection module 200 .

[0026] Integrated intrusion protection devices with routing functions, firewalls and intrusion prevention functions are used for the links that pass through, which improves the security of data transmission, and correctly installs and debugs each device in the network to ensure smooth links...

Embodiment 2

refer to image 3 , which is the second embodiment of the present invention, provides a distributed heating network and photovoltaic data collection system, including an external network module 100, and the external network module 100 is used to collect first data and transmit the first data. The network connection module 200 is connected to the external network module 100 through the Modbus TCP protocol. The intranet module 300 is connected to the network connection module 200 . The network connection module 200 initiates a connection request to the intranet module 300 and transmits the first data buffered in the connection module 200 to the intranet module 300 .

[0042] The first data includes heat network and photovoltaic data, the heat network data includes heating information for supplying heat to users, and the photovoltaic data includes power generation data of each photovoltaic power station, including power generation, power and total power generation, and is connecte...

Abstract

The invention discloses a distributed heat supply network and photovoltaic data acquisition method and system, and the method comprises the steps: collecting first data through an external network module, calling an interface drive program in a network connection module to initiate a connection request for the external network module through a collection interface client program, and transmitting the first data to the network connection module; the network connection module sends a connection request to the intranet module, establishes connection and transmits cached data of the extranet module to the intranet module; therefore, the intranet module obtains the first data from the extranet module through the network connection module; the first data enters an acquisition interface server of the intranet module and is transmitted to a real-time database agent to complete storage of the data in a database; the network security requirement is met, the limitation of the data transmission quantity between the Internet and the company intranet is avoided, heat supply network and photovoltaic data are transmitted to the company intranet, and the enterprise operation and management efficiency is improved. The method can be widely applied to the industrial internet.

Description

technical field [0001] The invention relates to the technical field of secure transmission of network data, in particular to a method and system for collecting distributed heat network and photovoltaic data. Background technique [0002] In recent years, in order to improve the efficiency of operation and management, the enterprises operating the heating network system of the power plant all need to collect, count and settle data through the Internet. In isolation, the data of the company's internal network and external network modules cannot be transmitted and communicated with each other. The heating network and photovoltaic data of each power plant cannot be transmitted to the regional company's internal network in real time, and the regional company cannot grasp the regional heating network and photovoltaic data in real time. Real-time data, in order to be able to grasp and count the real-time production data, financial settlement, etc. of the heating network system and ...
