All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, a positioning device is generally applied to a flight device to position the flight device. In the process of continuously positioning the positioning device in the flight device, the positioning device is used for acquiring positioning data in real time and monitoring the flight position of the flight device. However, the short message communication capability of the positioning device adopted in the prior art is poor, the positioning data cannot be transmitted in real time, and the real-time performance of monitoring the flight device is reduced.
Therefore, the application provides a data transmission method of positioning equipment, the network state of the communication network of the flight equipment is judged by judging the residual bandwidth, when the network state is good, the communication network of the flight equipment is directly adopted for positioning data transmission, the positioning data can be reliably transmitted to a server in real time, when the network state is poor, the positioning data is stored in a storage device, so that the positioning data can be downloaded through a downloading device, namely, the positioning data is temporarily stored when the network transmission cannot be carried out, the positioning data is prevented from being lost, the complete positioning data can be ensured to be acquired, the situation that the acquired positioning data is incomplete is avoided, and the reliability of acquiring the positioning data is improved.
Referring to fig. 1, fig. 1 is a flowchart illustrating a data transmission method of a positioning device according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, judging whether the residual bandwidth of the communication network of the flight equipment is larger than or equal to the transmission bandwidth of the positioning data; if yes, executing S102; if not, executing S103;
this step is intended to determine whether the remaining bandwidth of the communication network of the flight device itself at this time is greater than the transmission bandwidth of the positioning data. It should be noted that, in this step, since the remaining bandwidth of the communication network and the transmission bandwidth of the positioning data are changed in real time, the determination needs to be performed according to a preset period. The preset period can be set according to experience, the change frequency of the positioning data can be set, and the change of the flight condition of the flight equipment can be set. Flight condition changes include altitude changes, speed changes, direction changes, and course changes, among others.
S102, transmitting the positioning data to a communication network of the flight equipment through an avionic interface of the flight equipment so as to send the positioning data to a server through the communication network;
on the basis of S101, this step is intended to transmit positioning data over the communication network of the flying apparatus. Since the flying equipment cannot be connected to the ground network while flying, data communication can be performed only through a dedicated satellite network. And, because the short message communication ability of the positioning device is not enough, the positioning data can not be transmitted. Therefore, in order to ensure reliable data transmission, the data transmission is performed directly using a transit network. And data transmission is carried out only when the communication bandwidth of the flight equipment is judged to be vacant, so that the influence on the communication of the flight equipment is avoided as much as possible.
Optionally, the data sending method of the communication network in this step may include:
the positioning data is sent to a server through a satellite communication wireless transmission link in a communication network.
The satellite communication wireless transmission link can be an L satellite communication network or a Ka satellite communication network.
S103, storing the positioning data in the storage device so as to download the positioning data in the storage device through the positioning data downloading device.
On the basis of S101, this step is intended to temporarily store the positioning data. I.e. in the storage device, and transmits the positioning data to the outside when connected to the positioning data downloading device.
Optionally, the step of locating the data downloading device in this step may include:
the positioning data downloading equipment authenticates the positioning equipment;
and when the authentication is passed, downloading the positioning data from the storage device according to the preset format.
The preset format may be a format for encapsulating the positioning data in advance.
Optionally, the step in the positioning data downloading device of this embodiment may further include:
when the positioning data downloading equipment acquires the positioning data, the positioning data is sent to a ground network so as to send the positioning data to a server through the ground network.
It can be seen that the present alternative is primarily to illustrate how data in the storage device is transferred to the server.
To sum up, this embodiment judges flight device's communication network's network state through the mode of judging remaining bandwidth, when network state is good, the direct communication network who adopts this flight device carries out the positioning data transmission, guaranteed that the positioning data can be reliable transmission to the server in real time, when network state is relatively poor, then save the positioning data in storage device, so that download this positioning data through downloading equipment, just register the positioning data when can't carrying out network transmission, avoid the positioning data to lose, guarantee to acquire complete positioning data, avoid the incomplete condition to appear in the positioning data that acquires, the reliability that the positioning data acquireed has been improved.
The following further describes a data transmission method of a positioning device provided in the present application by using another specific embodiment.
In this embodiment, the method is applied to a beidou positioning system, and the method may include:
step 1, the positioning equipment judges whether the residual bandwidth of the communication network of the flight equipment is more than or equal to the transmission bandwidth of the positioning data; if yes, executing step 2; if not, executing the step 3;
step 2, transmitting the positioning data to a communication network of the flight equipment through an avionic interface of the flight equipment so as to send the positioning data to a server through the communication network;
and 3, storing the positioning data in the storage device so as to download the positioning data in the storage device through the positioning data downloading device.
The positioning data in the positioning equipment generally needs to be recorded once every 1 second, and the Beidou short message communication capacity is not enough for real-time transmission at present. The positioning data is thus processed by step 2 or step 3.
Step 2 is mainly that big dipper positioning unit transmits the communication network of aircraft to the location data through avionics interface, then gives the location data processing center through wireless transmission link real-time transmission such as L defending and leading, Ka defending.
Step 3, the Beidou positioning unit stores the positioning data in a storage space, and the size of the storage space is determined according to the flight time number in the data downloading period (assuming that the flight time number in the downloading period is Ls, and the length of data information such as the longitude and latitude height of each positioning is Nbit, the size of the storage space is L × N/8B); when the airplane is maintained on the ground, the storage space content is read from a maintenance interface through positioning data downloading equipment (the positioning data downloading equipment is generally a notebook computer, and the maintenance interface is generally an Ethernet interface); the positioning data downloading equipment transmits the data to the positioning data processing center through a wireless or wired ground network.
In addition, in the locating data downloading equipment, the authentication module needs to complete login authentication with the airborne Beidou equipment, and data downloading can be carried out.
It is thus clear that this embodiment judges flight device's communication network's network state through the mode of judging the residual bandwidth, when network state is good, the direct communication network who adopts this flight device carries out the location data transmission, guaranteed that the location data can be reliable transmission to the server in real time, when network state is relatively poor, then save the location data in storage device, so that download this location data through downloading equipment, just also with the location data temporary storage when can't carry out network transmission, avoid the location data to lose, guarantee to obtain complete location data, avoid the locating data incomplete condition to appear that the acquisition, the reliability that the location data obtained has been improved.
