the stabilized voltage power supply device 13 is respectively electrically connected with the satellite modem 11 and the shipboard power supply and is used for stabilizing the fluctuation voltage input by the shipboard power supply; that is, once the voltage supplied by the power supply to the offshore satellite broadband internet access device is unstable, the voltage stabilizing power supply device 13 can perform voltage stabilizing processing on the unstable voltage to meet the normal operation requirement of each power consumption component in the offshore satellite broadband internet access device;
a control board 14 connected with the stabilized voltage power supply device 13 by signals and used for controlling the stabilized voltage work of the stabilized voltage power supply device 13;
the main controller 15 is respectively in signal connection with the route switching module 12 and the control panel 14, and is electrically connected with the stabilized voltage supply device 13, and is used for intercepting and blocking the address or port of the blacklist for accessing the marine satellite, and recording and counting the flow in real time; in the actual production and use process, a white list and a black list aiming at the marine satellite network access are set in the main controller 15, the address or the port of the white list can be free from any interception and flow statistics, and the address or the port of the black list needs to be subjected to interception blocking setting, so that the black lists can not access the marine satellite network through the marine satellite broadband internet access device. Of course, the main controller 15 here may also be a main controller having a traffic statistic function, so as to facilitate real-time recording and statistics of traffic for accessing the marine satellite broadband internet access device resources and the marine satellite network resources, and a user can see a specific traffic condition in real time;

In the above-mentioned broadband internet access device for marine satellite provided by the embodiment of the present invention, the broadband internet access device for marine satellite can be connected with the marine satellite in a wireless manner, the satellite modem is used to demodulate the signal transmitted by the marine satellite, and the route switching module is used to convert the demodulated signal into the internet access signal for the user to use for internet access, so as to meet the internet access requirement of the user on the ship without paying expensive internet access cost, and once the power supply abnormality occurs to the power supply on the ship supplying power to the broadband internet access device for marine satellite, the control board controls the voltage stabilizing power supply device to enable the power consuming device in the broadband internet access device for marine satellite to supply relatively stable voltage, and in addition, the black list can not access the network of marine satellite through the broadband internet access device for marine satellite by the main controller for intercepting and blocking the address or port of the black list accessing the marine satellite, the controller is used for recording and counting the flow in real time aiming at accessing marine satellite broadband internet access equipment resources and marine satellite network resources, so that a user can see the specific flow using condition in real time, and a storage server can be read and controlled, so that application services of various terminal users are provided, and the use by the user is facilitated.
In practical application, each message sent by a user carries corresponding message characteristics, and the message characteristics are classified into the following categories: network protocol type (TCP/UDP), destination address (domain name or IP address), destination port number, packet payload; the traffic control can analyze the characteristics of different types of applications according to the above contents, and perform different processing on the characteristics, such as release or interception. Therefore, in order to prevent a large amount of satellite traffic from being consumed when a plurality of apps are upgraded by using an application market or a system after the mobile phone is connected with wifi, the method can intercept feature libraries such as various apps backstage and system upgrade through the main controller, and regularly update corresponding feature libraries; for example, the global DPI rule base is updated and intercepted every week, the DPI rule base is stored in a JSON manner, and the JSON file describes the protocol type, the destination address (IP address or domain name), the destination port number, the packet load characteristics, and other contents of the packet. Based on the above characteristics, the callback function implemented in the network protocol stack matches each message flowing through, and performs corresponding processing on the action (release or interception) defined after matching.
It should be noted that, in the above broadband internet access device for an offshore satellite provided in the embodiment of the present invention, the broadband internet access device may further include: and the host box is in signal connection with the main controller. The blacklist domain name, the corresponding characteristic message, various application services and other data can be issued to the host boxes of various ships through a multicast technology, so that the dynamic updating requirement is met, the application services are updated or added in time, and the corresponding application service content is added or deleted at the same time. The multicast IP address and the port number can be respectively defined aiming at different services, when the master station carries out multicast transmission, the files to be transmitted are split, and when the files are split, the packet sequence number, the packet length, the packet check and the like of each split multicast packet are defined. After the host box receives the multicast packet, the host box performs repackaging processing based on the splitting rule. Due to the characteristics of the multicast technology, the multicast technology does not ensure that the packet can be sent to the target host box, and can adopt a mechanism of one resource for multicast for multiple times and single-point download to ensure the integrity of the resource received by the host box.
It can be understood that, the user needs to perform real-time statistics on the traffic of the user using the marine satellite broadband internet access device resource and the marine satellite network resource through the wifi upper satellite network, so as to perform traffic charging on the back operation platform. The main controller in the invention mainly carries out flow byte statistics according to the user account and the MAC address, for example, the flow of a satellite network is recorded as satellite flow, the flow of a local application is recorded as Haego flow, and the main controller falls to a main box sub-database every 5s approximately so that a user can know the flow used by the user in time. Considering that one account can be used on a plurality of mobile phones, the account and the MAC address need to be recorded, and meanwhile, a user is prompted whether the account login of another mobile phone is kicked off when one account is logged in another mobile phone. The flow statistics is based on account numbers as flow statistics, and the same account number is likely to be logged in a plurality of equipment mobile phones at the same time point, so that a corresponding relation record of an MAC address and the account number exists, but basic service of the box mainly counts flow according to a packet of MAC address internet access (certainly, after the packet is transmitted to a cloud, an operation platform can perform statistical analysis according to a plurality of dimensions), and the unit is byte statistics.
