Description
Technical Field
The invention relates to an automatic adjusting device of a transmitting terminal applied to a marine buoy, and belongs to the technical field of marine buoys.
Background
The ocean contains rich resources, and the development and the utilization of the ocean resources form the working center of gravity of the 21 st century. Because the ocean weather changes very often, in order to better solve and develop the ocean, people acquire information such as wind speed, wind direction, temperature, humidity, atmospheric pressure, water flow and the like by means of a monitoring platform. The ocean buoy is an ocean hydrological weather monitoring platform which is widely applied at present, and is an automatic ocean hydrological weather observation station which takes an observation buoy anchored at sea as a main body. The ocean buoy is an unmanned automatic ocean observation station, can work for a long time, continuously and all-weather under any severe environment, solves the problem that coastal and island observation stations can only reflect weather and hydrologic conditions near coastal and island, and plays a great role in ocean navigation.
Ocean buoys are divided into two parts, above water and below water. The sensor is provided with a plurality of meteorological elements on the water part and is used for measuring the meteorological elements such as wind speed, wind direction and the like; the underwater part is provided with a plurality of sensors of hydrologic elements for measuring ocean hydrologic information such as ocean currents, waves and the like. The signals generated by various sensors are processed and packed by the instrument, and the packed messages are transmitted to a ground receiving station by the communication module. Since ocean buoys are often placed on the ocean far from the coast, data transmission can only be carried out using satellites. At present, satellite platforms carried by ocean buoys comprise an ARGOS communication system, an iridium communication system and the like, and the international satellite communication platforms have the problems of high cost, unsafe data transmission, untimely data transmission and the like, so that the ocean rights and interests of the country can not be well protected.
With the autonomous research and development of China, beidou satellite positioning and communication systems are put into use, and Beidou satellites are used for data transmission by ocean buoys in China. Because ocean buoy can make buoy back and forth left and right swing by the effort of seawave when especially inclement weather, install the big dipper terminal at ocean buoy top and also follow back and forth left and right swing, lead to the signal that the antenna transmitted can not successfully send the satellite, finally lead to the transmission success rate lower. The improvement of the transmission success rate of Beidou satellite communication becomes a popular subject of current research.
According to the marine autonomous observation platform data transmission method based on Beidou communication, disclosed by the patent number CN 103840924B, the Beidou communication system is utilized on the marine autonomous observation platform to realize real-time transmission of big data and breakpoint reissue of data after satellite communication is interrupted. The method aims at solving the problems that autonomous offshore platforms such as Beidou communication system bandwidth limitation, lagrangian drifting buoys and the like are susceptible to wind and wave to cause satellite communication interruption, adopts a mode that a plurality of groups of communication modules are used for parallel data transmission, data are packed and transmitted in a compressed mode, and the advantages of the plurality of groups of communication modules are utilized for complement transmission of lost data packets, so that real-time transmission of big data is realized, and the data transmission success rate and the data transmission efficiency are improved. The transmission method does not fundamentally solve the problem of communication interruption of the Beidou satellite, and the mode of utilizing the advantages of a plurality of groups of communication modules to reissue lost data packets is meaningless when the ocean buoy shakes forwards, backwards, leftwards and rightwards beyond the transmission gain range. The transmitting antenna cannot be automatically adjusted to be in the normal transmitting gain range, and the supplementing success can be realized only when the ocean buoy is restored to be in the normal range, and the supplementing is repeated at the moment, so that the time and the electricity are wasted. Therefore, designing an adjustable Beidou satellite communication device becomes an urgent problem to be solved.

The device of the embodiment further comprises a power supply module, wherein the power supply module is electrically connected with the modules such as the CPU control unit 6, the satellite receiving and transmitting terminal 2, the satellite receiving and transmitting antenna 3, the double-shaft inclination angle sensor 4, the first brushless direct current motor 1, the second brushless direct current motor 7 and the like.
As shown in fig. 3, the control system of the transmitting terminal adjusting device of the present embodiment mainly comprises a communication interface, a dual-axis tilt sensor 4, a rotation angle sensor 10, a power module, a CPU control unit 6, and a first brushless dc motor and a second brushless dc motor; the communication interface is arranged in the CPU control unit and is used for being connected with a control system of the ocean buoy to serve as a bridge for the cooperation of the emission terminal adjusting device and the ocean buoy; the biaxial inclination sensor 4 can detect inclination angles in the four directions of left, right, front and rear, and transmit detected signals to the CPU control unit 6; the rotation angle sensor 10 is used for measuring the rotation angle of the second brushless direct current motor 7, and when the rotation angle of the second brushless direct current motor 7 exceeds a preset rotation angle, the second brushless direct current motor 7 can only rotate in the opposite direction of the current movement direction, so that the wire is prevented from winding; the device of the embodiment presets the rotation limit angle of the second brushless direct current motor 7 as 720 degrees in the forward and reverse directions, the power supply module is used for supplying power to each module and is shared with the ocean buoy, and 24V direct current is processed through voltage rising and dropping when the power supply of the ocean buoy is used for supplying power; the CPU control unit is used for receiving the detection signal of the double-shaft inclination angle sensor 4 and controlling the first brushless direct current motor and the second brushless direct current motor to work; the first brushless direct current motor 1 drives the satellite receiving and transmitting terminal 2 and the satellite receiving and transmitting antenna 3 to rotate on a vertical plane when working; the second brushless DC motor 7 drives the satellite transceiver terminal 2 and the satellite transceiver antenna 3 to rotate in the horizontal plane when working, so that the front, back, left and right swinging of the ocean buoy is considered.
In general, the transmission gain of a normal Beidou antenna is concentrated between 15 ° and 165 ° horizontally, and when the Beidou antenna swings back and forth and left and right beyond this range, the signal transmitted by the antenna cannot be successfully transmitted to a satellite.
Because the transmitting terminal adjusting device of this embodiment is installed at the top of ocean buoy, clamping satellite transceiver terminal 2 and satellite transceiver antenna 3 on adjusting device, under the effect of wave, ocean buoy can the back and forth, left and right swing, adjusting device can also follow the back and forth, left and right swing.

As shown in fig. 4 and 5, when the transmitting terminal adjusting device of the present embodiment is used alone, the CPU control unit 6 first reads the angles of the two directions of the biaxial inclination sensor 4 and the angle value of the rotation angle sensor 10; the CPU control unit 6 judges according to the read inclination angles of the two directions; the angle detected by the front-rear direction sensor exceeds the normal emission angle range (15 ° to 165 °), and the first brushless dc motor 1 rotates to a position where the angle detected by the front-rear direction sensor is 0.
When the angle detected by the left-right direction sensor exceeds the normal emission angle range (15-165 degrees), judging whether the rotation angle sensor exceeds a preset rotation angle, and if so, reversing the second brushless direct current motor 7 to a position with the detection value of 0 of the sensor in the left-right direction; if the preset rotation angle is not exceeded, the second brushless direct current motor 7 rotates forward to a position with a sensor detection value of 0 in the left-right direction; because the second brushless direct current motor 7 rotates, the inclination sensor in the front-back direction is opposite to the swing direction of the ocean buoy, the adjustment of the first brushless direct current motor 1 is facilitated, after the second brushless direct current motor 7 is adjusted, the detection value of the sensor in the front-back direction exceeds the normal emission angle range (15 degrees to 165 degrees), and the first brushless direct current motor 1 rotates to the position where the detection value of the sensor in the front-back direction is 0.
The detection values of the front-back left-right direction sensors are beyond the normal emission angle range (15-165 degrees), whether the rotation angle sensor exceeds a preset rotation angle is judged, and if the rotation angle exceeds the preset rotation angle, the second brushless direct current motor 7 is reversed to a position with the detection value of 0; if the preset rotation angle is not exceeded, the second brushless direct current motor 7 rotates forward to a position with a sensor detection value of 0 in the left-right direction; after the second brushless dc motor 7 is adjusted, the first brushless dc motor 1 rotates to a position where the detection value of the front-rear direction sensor is 0.

When the transmitting terminal adjusting device is matched with the ocean buoy control system, the angle adjustment of the transmitting terminal and the satellite receiving and transmitting antenna is carried out after receiving a signal sent by the ocean buoy control system and failing to send. The CPU control unit 6 first reads the angles of the biaxial inclination sensor 4 in both directions and the angle value of the rotation angle sensor; judging whether the rotation angle sensor exceeds a preset rotation angle, and if so, reversing the second brushless direct current motor 7 to a position with a sensor detection value of 0 in the left-right direction; if the preset rotation angle is not exceeded, the second brushless direct current motor 7 rotates forward to a position with a sensor detection value of 0 in the left-right direction; after the second brushless dc motor 7 is adjusted, the first brushless dc motor 1 rotates to a position where the detection value of the front-rear direction sensor is 0. After the first brushless direct current motor and the second brushless direct current motor are regulated, the transmitting terminal and the receiving and transmitting antenna of the Beidou satellite are in the optimal transmitting angle range, so that preparation is made for retransmitting information to the ocean buoy.
The invention is not limited to the embodiments described above, but rather the technical solutions obtained by equivalent substitution are within the scope of the invention as claimed.
