Problems solved by technology

[0004] In view of the fact that the forward and reverse isolation devices are distributed between the software of the station test and the centralized control side, it is impossible to upload and download information through simple protocols such as TCP and UDP
In addition, in the construction of centralized control, there may be two forward and reverse isolation devices between the station test and the centralized control side, that is, the downlink and uplink of control commands not only go through the reverse gate and forward gate respectively. The gate also needs to go through two isolation settings, the upper and lower, and the procurement cost is relatively high.
At the same time, in the process of centralized control construction, because many software products have become mature, but according to the changing isolation architecture, the software needs to be modified more or less. The modified software is not universally applicable to various application scenarios. High manpower maintenance cost

Embodiment 1

[0057] This embodiment introduces a network gate adaptation module suitable for information interaction between the production control area and the management information area of ​​the electric power area I. Refer to image 3 As shown, it includes an upper-level adaptation unit and a lower-level adaptation unit; the upper-level adaptation unit and the lower-level adaptation unit transmit data through an isolation gatekeeper; the isolation gatekeeper includes a forward gatekeeper and a reverse gatekeeper;

[0058] The upper layer adaptation unit includes a TCP client submodule, a TCP service terminal module and a reverse gatekeeper client submodule; the lower layer adaptation unit includes a TCP service terminal module, a TCP client submodule and a reverse gatekeeper service terminal module;

[0059] The TCP client submodule of the upper layer adaptation unit receives the control instruction information issued by the control and forwarding center based on the TCP protocol; the r...

Embodiment 1-1

[0064] On the basis of Embodiment 1, the upper layer adaptation unit is also used for data interaction with the ECELL software connected to the real-time database. The ECELL software is used to update the collected data to the real-time database.

[0065] The composition of the gatekeeper adaptation module mainly includes:

[0066] 1) Upper layer adaptation unit

[0067] The upper layer adaptation unit includes a TCP client sub-module (TCP Client), a TCP server sub-module (TCP Server), a reverse gatekeeper client, a forward information cache queue, and a reverse information cache queue. Among them, the TCP client sub-module is mainly connected with the upper program, as shown in the figure, it is the program of ECELL and the control and forwarding center; the TCP service terminal module is mainly used to receive the information passing through the forward gate (mainly the feedback information of the control command and the power data information); the reverse gatekeeper clie...

Embodiment 2

[0071] For the gatekeeper adaptation module in embodiment 1 or embodiment 1-1, its communication method comprises:

[0072] The upper layer adaptation unit starts the TCP service terminal module and waits for the connection;

[0073] The lower-layer adaptation unit starts the TCP client sub-module, and sends a connection request to the TCP service terminal module of the upper-layer adaptation unit through the forward gatekeeper;

[0074] The TCP service terminal module of the upper-level adaptation unit responds to the connection request, and establishes a communication connection with the TCP client sub-module of the lower-level adaptation unit;

[0075] The TCP client sub-module of the lower-level adaptation unit sends a heartbeat detection message to the TCP service terminal module in the upper-level adaptation unit that has established a communication connection at a set time interval;

[0076] The TCP service terminal module of the upper layer adaptation unit responds to...

Abstract

The invention discloses a gatekeeper adaptation module and a data transmission system suitable for information interaction between a production control area and a management information area of a power I area. The data transmission system comprises a control forwarding center, an acquisition client, an isolation gatekeeper and a gatekeeper adaptation module, wherein the gatekeeper adaptation module comprises an upper layer adaptation unit and a lower layer adaptation unit, the control forwarding center is connected and communicated with the upper adaptation unit and / or the acquisition client in the gateway adaptation module through a communication adaptation module based on a TCP protocol, the acquisition client is connected and communicated with the lower-layer adaptation unit in the gateway adaptation module based on the TCP protocol, and the control forwarding center stores communication addresses respectively corresponding to each acquisition control end and each gatekeeper adaptation module. When the gateway adaptation module is applied, data interaction with upper-layer control forwarding center software and lower-layer acquisition client software can be carried out based ona TCP protocol, a communication mode of forward and reverse gatekeepers is shielded, loose coupling of upper and lower programs is realized, and a unified TCP communication interaction mode is provided.

Description

technical field [0001] The invention relates to the technical field of centralized control of power grids, in particular to a network gate adaptation module and a data transmission system suitable for information interaction between the production control area and the management information area of ​​the electric power area I. Background technique [0002] In the construction of a cross-platform new energy centralized control platform, according to the principle of "safe partition, dedicated network, horizontal isolation, and vertical authentication", the platform construction is generally divided into four areas, namely, safety area Ⅰ, safety area Ⅱ, and safety area Ⅲ Zone and Security Zone IV. Among them, the safety zone I and the security zone II adopt a dual-network and dual-link architecture, which realizes real-time monitoring, fault alarm, and production data storage functions on the side of the centralized control center, and completes the data access work of each mo...
