As shown in fig. 3, embodiment 1 provided by the present invention is specifically a typical multi-target real-time telemetry system composed of a plurality of telemetry targets and telemetry stations; in the system, a telemetering transmitter (marked as 2-5 in the figure) with a wireless receiving function is installed on a target needing data telemetering, data on the telemetering target is wirelessly transmitted to the telemetering transmitter, and the telemetering transmitter can receive an external wireless signal, respond to an instruction sent by a spectrum sensing management device and request a working mode to wirelessly send telemetering data according to the instruction;
when the multi-target remote sensing station works, a target detection signal is periodically transmitted outwards by the multi-target remote sensing station (number 1 in the figure), after the remote sensing target in a remote sensing coverage area receives the detection signal, a receiving and transmitting management module arranged in the multi-target remote sensing station returns a response signal to the remote sensing station through a wireless transmitting channel, and signal packaging data comprises self identification codes and link quality parameters; in the figure, the telemetry transmitter 2 is located outside the telemetry coverage area, cannot receive the detection information, and can establish a communication link (such as the telemetry transmitter 3) with a telemetry station after the transmitter enters the coverage area and receives a correct detection signal, execute a relevant configuration instruction to send a feedback signal (such as the transmitter 4), keep silent according to the configuration requirement, and transmit telemetry data in a frame-drawing mode or transmit the telemetry data at full speed (such as the transmitter 5).
A telemetry task management system arranged in a telemetry station checks frequency spectrum real-time data detected by frequency spectrum sensing equipment, allocates an available telemetry transmitting working frequency point for a certain telemetry target after receiving response information of the telemetry target, specifies a working mode according to the telemetry task requirement and link communication quality state of the target, and transmits the working mode in the form of instruction information through a wireless transmitting channel of the frequency spectrum sensing management equipment; meanwhile, the remote measurement task management system configures corresponding receiving frequency points, bandwidth, frame information and other related parameters for one channel of the multi-channel receiver, and receives remote measurement data sent by the remote measurement transmitter at any time;
the telemetering transmitter starts to transmit telemetering data according to a required working frequency point and a working mode after receiving the instruction, wherein the working mode is determined by parameters such as a sampling strategy, a transmission code rate, a modulation system, transmission power and the like;
when the frequency spectrum sensing management equipment detects a new telemetering target, frequency allocation and working mode determination of a working point of the telemetering target are carried out once according to the above process, and a corresponding receiving channel is configured in the multichannel receiver until all receiving channels are configured to receive telemetering data; when the telemetering task of a certain telemetering target is finished, the multichannel receiver stores the received telemetering data file, and the corresponding telemetering receiving channel is used for receiving the telemetering data of the next target.
As shown in fig. 4, embodiment 2 provided by the present invention is specifically a multi-telemetry target real-time telemetry system used in combination with a common telemetry transmitter; the system mainly comprises a plurality of telemetering targets which are formed by using telemetering transmitters (serial numbers 2-5 in the figure) with signal transceiving functions and common telemetering transmitters (serial numbers 8 and 9 in the figure), and a multi-target telemetering station (1 in the figure) to form a multi-target real-time telemetering system.
The telemetry transmitter in this example was used as in example 1.
When the common telemetry transmitter in the embodiment is used, as the common telemetry transmitter does not have a wireless receiving function, the common telemetry transmitter is not managed by the telemetry station, and only can continuously transmit telemetry data signals during work.
Before the telemetering task is started, according to a telemetering plan, working frequency points and working modes of the common telemetering transmitter are recorded in a telemetering task management system built in a telemetering station, the management system uses the working frequency points as reserved frequency points to be not distributed to other telemetering transmitters with wireless communication functions, and meanwhile, channels of the multichannel receiver are configured with receiving modes of corresponding frequency points and the like, so that telemetering data transmitted by the common telemetering transmitter can be received at any time.
When the total number of targets in the telemetry task is more than the number of channels of the receivers in the ground station, but the number of the telemetry targets for transmitting the telemetry data at the same time is not more than the number of channels of the receivers, the telemetry task management system can allocate the frequency point and the working mode of the telemetry transmitter of the access system to the receiving channel in a time-sharing round and patrol manner until the effective telemetry data of one target is received, the receiving state is maintained until the target telemetry task is completed, and the high-efficiency use of the receiving channel is realized.
When the common telemetry transmitter target is outside the telemetry coverage area (such as the transmitter 9 in the figure), although the telemetry data signal is transmitted continuously, the telemetry station cannot receive the signal until the telemetry data is received by matching the receiving channel arranged on the polling of the telemetry station after the telemetry station enters the coverage area (such as the transmitter 8 in the figure).
As shown in fig. 5, embodiment 3 provided by the present invention is specifically a multi-telemetry-target real-time telemetry system used in combination with a telemetry transmitter with a relay function;
when the distance between the target and the telemetering receiving station in the telemetering task is too far, the receiving capacity of the telemetering receiving station is exceeded, and the telemetering ground station cannot receive telemetering data in a certain time period due to influences of factors such as terrain and the like, according to the method application in the embodiment, the telemetering transmitter is used as a signal relay, and the data receiving capacity can be improved.
In example 1, a telemetry transmitter (telemetry transmitter 2 in fig. 5) is mounted on a telemetry target, and is within the range of a wireless communication area, because the telemetry data code stream is high and is outside the telemetry data receiving area of the telemetry receiving station, a telemetry transmitter (a relay transmitter 10 in figure 5) is added, which is within both the wireless communication zone and the telemetry reception zone of the telemetry reception station, the other telemetry transmitters ( telemetry transmitters 2, 3, 12 in figure 5) are within the wireless communication zone of the relay transmitter, however, since the telemetry transmitter (3 in fig. 5) is in the test coverage area of the telemetry receiving station, the telemetry receiving station can directly receive data, and at this time, the telemetry receiving station can load the configuration parameters of the relay transmitter to enable the relay transmitter to work in a relay mode, so that the data of the telemetry transmitter 2 or the telemetry transmitter 12 is forwarded to the telemetry receiving station in a relay manner.
Taking the example of forwarding the data of the telemetering transmitter 2, after the telemetering transmitters 2 and 10 enter the wireless communication coverage area, the telemetering receiving station loads the configuration parameters and the working parameters of the telemetering transmitter 2 according to the method for dynamically loading the configuration parameters in the embodiment 2, and simultaneously loads the configuration parameters of the telemetering transmitter 10 according to the parameter adaptability of the telemetering transmitter 2, so that frequency conversion transmission can be realized; when the telemetering transmitter 2 enters a telemetering data receiving area, the telemetering receiving station directly receives data, and data splicing is carried out through data processing software after the task is finished.
The telemetry system provided by the embodiment 3 adopts a relay method, and further reduces the data volume by methods such as reducing the sampling rate, thereby reducing the air data code rate and improving the telemetry distance.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
