Problems solved by technology

To ensure the high degree of synchronization of each subframe requires the master station to provide a standard clock and standard frequency, so it has the disadvantages of complex equipment, high cost, and low cost performance when the number of earth stations is small.

Embodiment 1

[0031] see figure 1 , a method for time division multiple access of a VSAT station provided in an embodiment of the present invention, specifically comprising:

[0032] 101: In the control software of the VSAT station server, set a channel time slot for the VSAT station, for example: 10:00 to 11:00 in the morning. In order to ensure that the data has sufficient time slots to be sent out completely, the channel time slots are generally set at more than 30 minutes, and as long as there is no conflict between the channel time slots of multiple VSAT stations, the channel time slots of the VSAT stations can be changed freely.

[0033] 102: When the VSAT station receives the request to send data, the server in the VSAT station reads the system clock of the server to obtain the first time point, and then inquires the channel time slot in the setting of the input control software, according to the inquired channel time slot , the server judges whether the first time point is within t...

Embodiment 2

[0041] see figure 2 , a VSAT station time division multiple access server provided by the embodiment of the present invention, specifically includes:

[0042] A setting module is used to set a channel time slot for the VSAT station;

[0043] The first processing module is used for after the setting module sets the channel time slot for the VSAT station, when the VSAT station receives a request to send data, the VSAT station reads the system clock, obtains the first time point, and judges the Whether the first time point is within the channel time slot, if it is within the channel time slot, the data is allowed to be sent; otherwise, the data is prevented from being sent.

[0044] further, figure 2 The server shown also includes:

[0045]The second processing module is used for the first processing module to send the data to the satellite modem of the VSAT station after the first processing module allows sending the data, and set a small time period, every a small time se...

Embodiment 3

[0048] see image 3 , a VSAT station time division multiple access system provided in an embodiment of the present invention, specifically including: a server, a satellite modem, an outdoor unit, and an antenna;

[0049] The servers include:

[0050] A setting module is used to set a channel time slot for the VSAT station;

[0051] The first processing module is used for after the setting module sets the channel time slot for the VSAT station, when the VSAT station receives a request to send data, the VSAT station reads the system clock, obtains the first time point, and judges the Whether the first time point is within the channel time slot, if it is within the channel time slot, the data is allowed to be sent; otherwise, the data is prevented from being sent;

[0052] The second processing module is used for the first processing module to send the data to the satellite modem of the VSAT station after the first processing module allows sending the data, and set a small time...

Abstract

The invention discloses a method, a server and a system of VSAT station time-division multiple address, belonging to the satellite communication field. The method includes the following steps: a channel time slot for a VSAT station is set; when the VSAT station receives the request of sending data, the VSAT station reads a system clock to get a first time point, and judges whether the first time point is within the channel time slot, if so, the data is permitted to be sent; if not, the data is prevented from being sent. The server includes: a setting module and a first processing module. The system includes: the server, a satellite modem, an outdoor unit and an antenna. The invention realizes sharing one satellite channel by multiple VSAT stations and realizes time-division multiple address without a main station, and is characterized by simple device, low cost and higher cost performance when the number of earth stations is small.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a method, server and system for time division multiple access of a VSAT station. Background technique [0002] VSAT (Very Small Aperture Terminal, Very Small Aperture Terminal) refers to a type of very cheap intelligent small or micro earth station with a very small aperture antenna, which can be easily installed at the user's place. The VSAT satellite communication network generally consists of a large number of VSAT small stations and a main station working together to form a satellite communication network with wide-area sparse routing (many stations and small traffic volume of each station). The VSAT user data terminal can be directly connected to the computer network to complete communication tasks such as data transmission, file exchange, and image transmission, thereby getting rid of the problem of long-distance communication ground interruption stations. Using VSAT ...
