In addition, because the safety protection capability of the terminal communication network is insufficient, effective isolation of control instructions cannot be achieved, and the reliability is poor. The load side has multiple networking modes and multiple communication protocols, lacks a unified monitoring tool for a load management terminal and a communication network, and cannot realize the visibility, observability and controllability of terminal equipment and network states. The novel bidirectional interaction of the power load management system mainly has the following problems:
(1) The problem of dispersibility of multiple domains, the decentralized construction causes communication to cross two levels of end edges/network clouds and two areas of public networks/private networks, and an effective and reliable communication architecture needs to be provided.
(2) The reliability of interaction is poor, network coverage blind areas are more, real-time reliability of scheduling control instructions is poor, and reliable communication means and a service quality guarantee mechanism are lacked.
(3) The access safety problem is that the open communication networks such as 4G/5G public network, wireless ad hoc network and the like cannot resist network attacks such as brute force cracking, man in the middle and the like, and the access authentication and the safety protection of the terminal are to be enhanced.
(4) The problem of high efficiency of management and control is that the bearing relation between the service and the network resource is complex, a plurality of networking modes and a plurality of communication protocols coexist, and the network agility and the quality are difficult to ensure.

The multi-channel intelligent energy unit terminal has the problem of multiple addresses, as shown in fig. 7, because the access service master station is generally deployed in province and city, the access node is fixed; the intelligent energy unit terminal is connected to the main station through different channels, and a plurality of addresses exist from different channels to the same terminal at the main station side due to the differences of communication modes, networking and the like, so that the main station is not beneficial to managing terminal assets. The original connection relationship is shown in fig. 7. The connection relationship after the multi-network communication gateway is added is shown in fig. 8. The negative control master station 1 sends data to a master station gateway in a security access area, wherein the data comprises a master station address; the master station gateway selects a communication channel to transmit data, the data is transmitted to the terminal gateway, and the terminal gateway sends the data to the terminal address of the intelligent energy unit 2 according to the type of the data.
The implementation technical scheme is as follows: the terminal-side multichannel intelligent energy unit 2 corresponds to a plurality of communication modules or communication devices, and each communication device is closely connected with the intelligent energy unit 2 through a local serial port or other interface. Each communication module represents a field terminal node and a plurality of communication modules or devices interface with an intelligent energy unit 2. A plurality of field terminal nodes are displayed in the master station system, but all correspond to the service terminals of the same intelligent energy unit. When the multi-communication channel at the master station side is accessed, the master station is unified and definite because the convergence exchange equipment is arranged to process the multi-communication channel at the master station side through the safety access area before the master station is accessed. Therefore, the invention gathers the multipath communication by adding the terminal gateway at the terminal side to form a unified service terminal (intelligent energy unit) address. The uplink flow of the multi-communication channel acquisition control separation gateway system works in the manner shown in fig. 9.
The channel port table of the terminal gateway comprises port numbers corresponding to all channels of the terminal gateway, channel source addresses corresponding to all channels and channel destination addresses. For example, channel 1 (port 01, source address 1, destination address 1), channel 2 (port 02, source address 2, destination address 2). The traffic data frames and the channel data frames of the terminating gateway are shown in fig. 10 and 11. In the uplink flow, the source address in the service data is the service terminal address, and the destination address is the service master station address. The channel source address is the gateway side address of the channel terminal, and the channel destination address is the gateway side address of the channel master station.
The downlink flow of the multi-communication channel acquisition control separation gateway system operates in the manner shown in fig. 12. The channel port table of the master station gateway comprises port numbers corresponding to all channels of the master station gateway, channel source addresses corresponding to all channels and channel destination addresses. For example, channel 1 (port 01, source address 1, destination address 1), channel 2 (port 02, source address 2, destination address 2).
Traffic data frames and channel data frames for the primary station gateway are schematically shown in fig. 13 and 14. In the service data in the downlink flow, the source address is the address of the service master station, and the destination address is the address of the service terminal. The channel source address is the gateway side address of the channel master station, and the channel destination address is the gateway side address of the channel terminal.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
