Problems solved by technology

For example, if a single-card Beidou communication terminal with a fixed communication period of 30 seconds is used, each location information message contains a positioning information. Without considering the delay of the Beidou system, the monitoring platform can only receive 1 Assuming that the average speed of a vehicle or drone is about 100Km / h, the location information of a moving target is calculated based on 30S communication once, and the distance between two adjacent points is about 900 meters. If a short message is sent Or if there is a failure in the receiving process, it is difficult to obtain an accurate positioning position, which seriously affects the supervision effect

Embodiment 1

[0050] see figure 1 with figure 2 , the positioning information sending method proposed in this embodiment specifically includes:

[0051] The present invention adopts the method of progressive card deployment in the Beidou communication terminal. Within a communication cycle, N Beidou communication cards send a set of positioning information to the opposite end at different times. Here, N is greater than or equal to 2, that is to say, At least two Beidou communication cards must be arranged on the sender side of the Beidou communication terminal.

[0052] In this embodiment, take the arrangement of 4 cards in the Beidou communication terminal as an example (that is, N is equal to 4) as an example, and the communication cycle of each Beidou communication card is M seconds. Here, each Beidou communication card The communication cycle of the card is set to 30 seconds as an example for specific description.

[0053] First of all, the N Beidou communication cards start timing ...

Embodiment 2

[0057] see image 3 The positioning information sending device 5 proposed in this embodiment specifically includes a positioning information sending module, which is used to send a set of positioning information to the opposite end at different times by N Beidou communication cards within a communication cycle, wherein N is greater than or equal to 2 .

[0058] In addition, the positioning information sending device 5 also includes: a timing module, which is used to start counting N pieces of Beidou communication cards from the moment of power-on with M / N seconds as timing intervals, wherein the communication period of each Beidou communication card Both are M seconds.

[0059] In addition, the positioning information sending device 5 also includes: a sampling starting point setting module 1, a sampling interval setting module 2 and a positioning information sampling module 3, wherein the sampling starting point setting module 1 is used to set M-(N-1)*( M / (N*L)) time is set ...

Embodiment 3

[0062] The present embodiment provides a positioning information receiving method comprising: sequentially receiving N sets of positioning information sent by N Beidou communication cards, and calculating the receiving delays of N sets of L positioning information respectively, so as to set up 4 Beidou communication cards, each The communication cycle of the Beidou communication card is set to 30 seconds, and each Beidou communication card collects 3 sampling points (L=3) as an example, then in the positioning information receiving device 6, the maximum delay is increased from the original M=30 seconds to the present M(L-1) / (N*L)=5 seconds, which is a qualitative improvement in the real-time supervision of the supervision target.

[0063] To sum up, the positioning information receiving method provided by this embodiment includes: sequentially receiving N sets of positioning information sent by N Beidou communication cards, and calculating the receiving delays of N sets of L po...

Abstract

The invention relates to the field of information technology, and provides a positioning information sending method and device, a positioning information receiving and device, and a positioning information transmission system. The positioning information sending method comprises the following step: during a communication cycle, N Beidou communication cards respectively send groups of positioning information to an opposite terminal at different moments, wherein N is equal to or larger than 2. Through the settings, when the Beidou communication cards are used for sending the positioning information, the multiple pieces of positioning information can be acquired and sent within one communication cycle, so that a user can obtain the positioning information which is denser and more accurate, and monitoring effects for a moving target can be improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a positioning information sending method and device, a receiving method and device, and a transmission system. Background technique [0002] The Beidou Navigation System is a widely used satellite navigation system used to determine the geographic latitude and longitude information for users. At present, the Beidou navigation system is composed of more than 30 satellites, covering the Asia-Pacific region. Among them, the short message module is a major technical advantage of the Beidou navigation system. play a major role. [0003] In recent years, the short-message communication technology based on a single card is to use a single short-message Beidou communication card to realize remote supervision of moving targets such as vehicles and drones. For example, since light and small unmanned aerial vehicles are "low, slow, and small" flight targets, our country's exi...
