This invention addresses the problem in existing technologies where WiFi signals are easily interfered with. In complex electromagnetic environments such as substations, electromagnetic interference generated by other electronic devices and power equipment can affect the stable transmission of WiFi signals, leading to data loss or transmission delays. The invention provides a power wireless communication system and a smart grid. It relates to the field of power wireless communication systems. The system includes a sensing layer, a network layer, and an application layer. The sensing layer includes at least one power monitoring terminal for collecting power equipment operation data. The network layer includes a secure access module, a WAPI authentication server, and a communication network architecture. The secure access module connects to both the power monitoring terminal and the WAPI authentication server via a WAPI encrypted channel. The communication network architecture includes a core routing unit and a wireless access unit. The application layer includes a power control center and a security audit module. This invention constructs a secure protection system for data acquisition, transmission, processing, and control.

The invention discloses a method, a device, equipment and a medium for improving communication efficiency of multiple paths of PSAM cards, and relates to the technical field of terminal security. The method comprises the following steps: enabling multiple paths of PSAM cards to share one path of IO (Input / Output) port, a power supply and a control signal, and controlling the PSAM card selected by the IO port through a switching pin signal of terminal equipment and a switching circuit; sequentially selecting each PSAM card through a switching pin under a default baud rate, acquiring ATR data corresponding to each PSAM card, executing PPS negotiation operation to complete baud rate matching, and storing; according to the PSAM card selected by the service APP, the IO port is switched through the switching pin to select the corresponding PSAM card, the Baud rate of the terminal IO port is switched according to the negotiation Baud rate value corresponding to the PSAM card, then instruction interaction is executed, and after instruction interaction is finished, the IO port recovers the default Baud rate. According to the method, the device, the equipment and the medium for improving the communication efficiency of the multi-path PSAM card provided by the invention, the communication efficiency of the multi-path PSAM card is improved.

The invention relates to the technical field of power supply grid service, in particular to a power supply grid work order intelligent identification generation and whole-process management and control system which comprises a work order intelligent processing module, a telephone traffic management module, a data storage module and a safety access module. The intelligent work order processing module is used for automatically identifying customer appeal types, generating work orders, combining repeated work orders and managing the whole life cycle of the work orders; the telephone traffic management module is used for managing binding and unbinding of the virtual number of the power supply grid, and associatively storing a call record and a corresponding work order; the data storage module adopts a MySQL master-slave architecture and is used for storing real-time data and realizing data backup and query service; and the security access module realizes internal and external network isolation through a multi-physical network card special server. The work order processing efficiency can be improved, the system safety is guaranteed, and the service quality of the power supply grid is optimized.

The invention relates to the technical field of transaction service platforms, and discloses a fourth-party intellectual property transaction system which comprises an intellectual property transaction system. The intellectual property transaction system comprises a user management module, an intellectual property information management module, a transaction management module, a contract management module, a payment and settlement module and a report and analysis module. The user management module is responsible for managing user information of the system and has the functions of user registration, login and authority management; and the intellectual property information management module is used for managing and maintaining relevant information of the intellectual property and realizing operations of inputting, querying, modifying and deleting the intellectual property. Through mutual cooperation of the units in the security access module, the security access module can solve security vulnerabilities in time, so that enhancement of trust of a user to a platform is facilitated, transaction in a system of information and assets of the user is effectively protected, and meanwhile, the solution of the security vulnerabilities is helpful to reduce potential risks.
