[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] like Figure 1 As shown: Embodiment 1 of the present invention is: The power grid emergency intelligent portable communication system based on Tiantong satellite phone includes an operation control system, a central station, a communication satellite, a business management station, a satellite terminal and a handheld terminal, and the operation control module, the central station, and the business management station are all connected to the communication satellite by signal; the handheld terminal is connected to the communication satellite through the satellite terminal; The satellite terminal includes a Tiantong satellite phone module, a data processing unit and a power management module. The Tiantong satellite phone module is used to realize the communication connection between the handheld terminal and the Tiantong satellite. The data processing unit is used to process communication data, including data compression, encryption and decompression, decryption operations, as well as analysis of instruction information and execution result feedback. The power management module is used to power the device.

[0014] In this embodiment, the power management module includes a lithium battery and a USB charging module; the lithium battery is a 4700mAh, 7.2V lithium battery, and the charger is a 5V / 4A, 20W specification; In this embodiment, the operation and control system is used to perform orbit and attitude control on the communication satellite, and to monitor, manage, plan and dispatch satellite equipment; Among them: The orbit control of communication satellites is to monitor the orbit parameters of satellites in real time through the measurement and control station. When the satellite orbit is found to be deviated, the operation and control system will send instructions to the satellite to make orbit corrections to ensure that the satellite operates stably on the predetermined orbit. For example, geostationary orbit satellites need to remain above a specific longitude. The operation and control system can prevent the satellite from drifting due to factors such as solar wind and the non-spherical gravity of the earth through orbit control: The attitude control of communication satellites is to ensure that the antennas and sensors on the satellites can accurately point to the target direction. By adjusting the satellite attitude, the communication antenna can be aligned with the ground station or service area to achieve efficient communication and data transmission. For example, the communication satellite needs to accurately point the antenna to the central station and user terminal on the ground, and the operation and control system achieves this goal through attitude control.

[0015] Satellite equipment monitoring and management refers to the operation and control system's real-time monitoring of various equipment on the satellite, including power systems, communication equipment, sensors, etc. Once an abnormality or failure is found in the equipment, timely measures can be taken to deal with it, such as switching to backup equipment, performing fault repair operations, etc. For example, if the performance of the power module on the satellite degrades, the operation and control system can enable the backup power supply through remote control to ensure the normal operation of the satellite.

[0016] Planning and scheduling is mainly responsible for formulating satellite mission plans and scheduling. According to factors such as user needs and communication business volume, the satellite's working mode and resource allocation are reasonably arranged to improve the efficiency of satellite use.

[0017] For example, during peak communication periods, the operation and control system can dispatch satellites to increase communication coverage and resource allocation in specific areas to meet the communication needs of users.

[0018] In this embodiment, the central station includes a measurement and control station, an application management center, a decision support center and a gateway station; The tracking and control station is used to track, telemeter and remotely control the satellite, specifically to track, telemeter and remotely control the satellite. It is responsible for monitoring the satellite's orbital parameters and working status, and sending instructions to ensure the normal operation of the satellite. For example, when the satellite's orbit deviates slightly, the tracking and control station can adjust the satellite's attitude and orbit by sending instructions. The application management center is used to manage and configure satellite communication applications. This includes scheduling and resource allocation for communication needs of different users. For example, when multiple users request communication services, the application management center will reasonably allocate communication frequency bands and time according to priority and resource conditions.

[0019] The decision support center is used to provide data processing and decision support functions, specifically to provide data processing and decision support functions. It collects and analyzes data from various subsystems to assist managers in making reasonable decisions. For example, when a communication link fails, the decision support center can provide troubleshooting suggestions and solutions by analyzing historical data and current status.

[0020] The gateway station serves as an interface between the satellite communication network and the ground network, specifically as an interface between the satellite communication network and the ground network. It is responsible for realizing the conversion and connection between the satellite communication link and the ground communication link. For example, the gateway station can convert the signal received by the satellite into a format that can be recognized and processed by the ground network, and vice versa.

[0021] In this embodiment, the service management station is used to manage and monitor satellite communication services, specifically to manage and monitor satellite communication services. It ensures the quality and stability of communication services, and handles business requests, billing and other related matters. For example, the service management station can monitor communication traffic, prevent network congestion, and count and bill users' communication costs. Through the coordinated work of these subsystems, the central station ensures the efficient and stable operation of the satellite communication system, realizes the control of satellites, the management of communication resources and the guarantee of services.

[0022] In this embodiment, when communicating, the operator connects to the satellite terminal through a handheld terminal (mobile phone), and then sends a signal to the communication satellite (Tiantong satellite) through the satellite terminal. The Tiantong satellite dials another satellite terminal to be connected to achieve satellite communication.

[0023] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0024] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
