Description

Technical Field

[0001] The present invention belongs to the technical field of gateway communications and relates to a multi-communication channel acquisition and control separation gateway system. Background Art

[0002] The new power system requires real-time aggregation and efficient processing of massive data from all links, and puts higher requirements on data collection, transmission, storage and use, especially the massive load management terminal points are numerous and widespread, the application scenarios are complex, the control strategies are very different, and the protection boundaries of different information security partitions are blurred.

[0003] Currently, load management communication channels are decentralized and independently constructed, primarily utilizing 230MHz wireless private networks and 4G wireless public networks. Network terminal coverage exceeds 90%, and a small number of customers have also established fiber-optic channels, which provide some support for load monitoring and control. However, for control services, the current reliance on power wireless and fiber-optic private networks is costly. The networking interaction protocols based on 230MHz digital radios are outdated, bandwidth is limited, and network reliability is insufficient. Furthermore, the security of 5G public networks remains to be verified. For data collection services, increasing the frequency of data collection hinders the communication system from meeting the accuracy and timeliness requirements of the new power load management system. Load management terminal access scenarios are complex and diverse, and communication coverage in high-rise buildings and basements is poor. This results in insufficient granular monitoring capabilities for adjustable and interruptible loads, a lack of coordination between different loads, and poor timeliness. The existing network coverage and service quality cannot meet the requirements of multi-timescale, zoned and graded demand response, orderly power consumption, and precise load control. Furthermore, the terminal communication network's insufficient security capabilities prevent effective isolation of control commands, resulting in poor reliability. On the load side, multiple networking methods and communication protocols coexist, and there is a lack of load management terminals and unified communication network monitoring tools, making it impossible to visualize, observe, and control the status of terminal devices and networks. The two-way interaction of the new power load management system mainly has the following problems:

[0004] (1) The problem of multi-domain dispersion. Decentralized construction causes communications to span two levels: end-edge / network-cloud, and public / private networks. Therefore, an effective and reliable communication architecture needs to be proposed.

[0005] (2) Interaction reliability issues: there are many blind spots in network coverage, poor real-time reliability of dispatching and control instructions, and a lack of reliable communication means and service quality assurance mechanisms.

[0006] (3) Access security issues. Open communication networks such as 4G / 5G public networks and wireless ad hoc networks cannot resist network attacks such as brute force cracking and man-in-the-middle attacks. Terminal access authentication and security protection need to be strengthened.

[0007] (4) The problem of efficient management and control. The relationship between business and network resources is complex. Multiple networking modes and multiple communication protocols coexist. It is difficult to achieve agile network operation and maintenance and quality assurance. Summary of the Invention

[0008] The purpose of the present invention is to solve the problems of large dispersion of two-way interactive areas, poor security of communication networks, poor interaction reliability and low management and control efficiency in the existing power load management system, and to provide a multi-communication channel acquisition and control separation gateway system.

If there are control frames, it belongs to control business data; if there are data frames, it belongs to collection business data.

[0061] The acquisition communication module is any corresponding module between the second master station communication module ... the Nth master station communication module and the second terminal communication module ... the Nth terminal communication module.

[0062] Example:

[0063] The master station gateway and terminal gateway structures of the present invention are respectively as follows Figure 3 and Figure 4 As shown, the master station gateway consists of a first protocol processing module and a multi-channel master station communication module. The first protocol processing module determines whether the master station data is control service data or collection service data. If a control frame is present, it is control service data; if a data frame is present, it is collection service data. The terminal gateway consists of a second protocol processing module and a multi-channel terminal communication module. The second protocol processing module determines whether the collection data is control service data or collection service data. If a control frame is present, it is control service data; if a data frame is present, it is collection service data.

[0064] The multi-channel master station communication module includes a first master station communication module, a second master station communication module...an Nth master station communication module; the multi-channel terminal communication module includes a first terminal communication module, a second terminal communication module...an Nth terminal communication module; the first master station communication module exchanges information and data with the first terminal communication module; the second master station communication module exchanges information and data with the second terminal communication module; and the Nth master station communication module exchanges information and data with the Nth terminal communication module.

[0065] For example, in the 104 protocol, the control frame is 68 04 XX XX XX XX, and the data frame is 68 13 XX XX XX XX XX XX XXXX XX XX XX. If a control frame is detected, the data belongs to control service data; if a data frame is detected, the data belongs to collection service data.

[0066] The communication channel between the first master station communication module and the first terminal communication module is a power wireless private network channel; the communication channels between the second master station communication module and the second terminal communication module, and between the Nth master station communication module and the Nth terminal communication module are all public network channels.

[0067] After receiving the channel data, the terminal gateway transmits it to the main station. Its operation process is as follows Figure 5 As shown; the terminal gateway receives the data of the smart energy unit and then determines whether it is a control business instruction; if so, the control channel is selected to send it to the load control master station, that is, the communication channel between the first master station communication module and the first terminal communication module; if not, the acquisition channel is selected to send it to the load control master station, that is, any communication channel between the second master station communication module and the second terminal communication module, and the Nth master station communication module and the Nth terminal communication module.

[0068] After receiving the channel data, the master gateway transmits it to the smart energy unit. The operation process is as follows: Figure 6 As shown:

[0069] The master station gateway receives the data from the load control master station and then determines whether it is a control business instruction; if so, it selects the control channel to send to the smart energy unit, that is, the communication channel between the first master station communication module and the first terminal communication module; if not, it selects the acquisition channel to send to the smart energy unit, that is, any communication channel between the second master station communication module and the second terminal communication module, or between the Nth master station communication module and the Nth terminal communication module.

[0070] Multi-channel smart energy unit terminals have multiple address problems, such as Figure 7 As shown, because the access service master station is generally deployed in provinces and cities, the access node is fixed; the smart energy unit terminal reaches the master station through different channels. Due to differences in communication methods and networking, on the master station side, different channels to the same terminal will have multiple addresses, which is not conducive to the master station's management of terminal assets. The present invention proposes an increase based on multi-network gateways to achieve one terminal corresponding to one address, which is clear and convenient for management on the master station side. The original connection relationship is as follows Figure 7 As shown. The connection relationship after installing the multi-network communication gateway is as follows Figure 8 The load control master station sends data, including the master station address, to the master station gateway in the secure access zone. The master station gateway selects a communication channel to transmit the data to the terminal gateway, which then sends the data to the terminal address of the smart energy unit based on the data type.

[0071] The technical solution is realized as follows: the multi-channel intelligent energy unit at the terminal side corresponds to multiple communication modules or devices, and each communication device is connected to the intelligent energy unit through a local serial port or the like. Each communication module represents a field terminal node, and multiple communication modules or devices are connected to one intelligent energy unit. Multiple field terminal nodes are displayed in the host system, but actually correspond to the business terminal of the same intelligent energy unit. When multiple communication channels are accessed at the host side, the host is unified and clear because the host is accessed through a security access area and a convergence switching device is used for processing. Therefore, the application forms a unified business terminal (intelligent energy unit) address by adding a terminal gateway at the terminal side to converge multiple communication channels. The working mode of the uplink process of the multi-communication channel control separation gateway system is shown in Figure 9 .

[0072] The channel port table of the terminal gateway includes the port number corresponding to each channel of the terminal gateway, the channel source address corresponding to each channel, and the channel destination address. For example, channel 1 (port 01, source address 1, destination address 1), channel 2 (port 02, source address 2, destination address 2), and so on. The business data frame and the channel data frame of the terminal gateway are shown in Figure 10 and Figure 11 . In the uplink process, the source address in the business data is the business terminal address, and the destination address is the business host address. The channel source address is the terminal gateway side address of the channel, and the channel destination address is the host gateway side address of the channel.

[0073] The working mode of the downlink process of the multi-communication channel control separation gateway system is shown in Figure 12 . The channel port table of the host gateway includes the port number corresponding to each channel of the host gateway, the channel source address corresponding to each channel, and the channel destination address. For example, channel 1 (port 01, source address 1, destination address 1), channel 2 (port 02, source address 2, destination address 2), and so on.

[0074] The business data frame and the channel data frame of the host gateway are shown in Figure 13 and Figure 14 . In the downlink process, the source address in the business data is the business host address, and the destination address is the business terminal address. The channel source address is the host gateway side address of the channel, and the channel destination address is the terminal gateway side address of the channel.

[0075] The above is only a preferred embodiment of the application and is not used to limit the application. For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
