In recent years, multi-mode communication technology has been gradually applied in the power field, and the system robustness is improved by combining multiple communication modes.

The multi-mode fusion communication module 102 integrates a satellite communication unit 113, a terrestrial wireless unit 114, and a self-organizing network unit 115. The aforementioned solution solves the technical problems in the prior art where there is a lack of adaptive capability in multi-mode communication path selection, and the inability to dynamically optimize communication routes according to real-time link status and service requirements, resulting in low efficiency of communication resource utilization and difficulty in guaranteeing service transmission quality.

[0021] In this specific implementation, the main control module 101 runs an intelligent routing decision algorithm, which constructs a dynamic link quality matrix based on the signal strength, bit error rate, transmission delay and link stability data collected in real time by the link quality monitoring circuit; the algorithm dynamically selects the optimal physical communication unit for different types of power service data through the radio frequency switch matrix. The login module 111 provides a secure and convenient way for users to access the human-computer interaction module 109; the permission control module 112 combines the verified user identity and dynamically executes the ABAC policy engine to make real-time permission decisions based on the user identity.

[0022] The edge computing module 107 has a built-in single-phase grounding fault identification algorithm for power distribution networks. This algorithm integrates the zero-sequence voltage and current data from the power data acquisition module 103 and performs fault analysis by calculating the fifth harmonic ratio and signal abrupt change points.

[0023] The multi-mode fusion communication module 102, the power data acquisition module 103, the power management module 104, the environmental perception and protection module 105, the security encryption module 106, the edge computing module 107, the positioning and timing module 108, the human-computer interaction module 109, and the storage module 110 are all connected to the main control module 101. The login module 111 is connected to the human-computer interaction module 109, and the access control module 112 is connected to the login module 111. By introducing an intelligent routing decision algorithm, this invention can dynamically select the optimal communication path based on the real-time link quality matrix, significantly improving the efficiency of communication resource utilization and the reliability of power business data transmission. At the same time, the access control module 112, which integrates the ABAC policy engine, realizes fine-grained and dynamic access permission management, and works in conjunction with the intelligent routing mechanism to jointly construct an integrated power communication terminal with both efficient data transmission and high security capabilities. This approach solves the technical problems in existing technologies that lack adaptive capabilities in multi-mode communication path selection, cannot dynamically optimize communication routes based on real-time link status and business needs, resulting in low efficiency in communication resource utilization and difficulty in guaranteeing service transmission quality.

[0024] Secondly, the satellite communication unit 113 integrates the BeiDou-3 short message subunit, the TianTong-1 voice data subunit, and the low-orbit Internet of Things subunit, and each subunit works in coordination through a time-division multiplexing controller; The ground wireless submodule 114 supports 5G / 4G private network access and interacts with the main control module 101 through the baseband processing chip. The self-organizing network unit 115 adopts a multi-hop relay protocol and realizes direct communication between terminals through the radio frequency front-end chip; The satellite communication unit 113 is equipped with an intelligent routing controller, which collects the status of each communication unit in real time through the link quality monitoring circuit and executes a dynamic routing selection algorithm.

[0025] Furthermore, the power management module 104 includes: The main power supply unit 119 uses a high-density lithium-ion battery pack and communicates with the main control module 101 through a power management chip.

[0026] Meanwhile, the security encryption module 106 adopts a multi-layer security architecture: A hardware encryption layer, wherein the hardware encryption layer accelerates the national cryptographic algorithm through an encryption chip; A link encryption layer, which encrypts transmitted data in real time; An application encryption layer is applied to provide end-to-end protection for business data. The security encryption module 106 performs key negotiation and data encryption / decryption operations with the main control module 101 through the security coprocessor interface.

[0027] Furthermore, the main control module 101 integrates an anomaly detection mechanism 116 and an alarm mechanism 117. The anomaly detection mechanism 116 monitors the key parameters of the main control module 101 in real time and drives the alarm module to display corresponding colors and modes according to preset priority logic.

[0028] Furthermore, the main control module 101 also integrates a remote restart mechanism 118, to which the main control module 101 periodically sends a "heartbeat" signal. If the remote restart mechanism 118 does not receive a heartbeat within a preset time, it determines that the main control program has "crashed" and automatically triggers a terminal restart. When receiving a remote restart command, strict identity token verification is performed to prevent malicious users from arbitrarily restarting the device.
