Detailed Description
The invention will now be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the invention provides an electric field and magnetic field in-place detection device for a floating platform, which solves the problems of extension and retraction of an electric field sensor in cooperation with a balloon platform, flight calibration and vector pointing transmission of a magnetic field sensor, and installation of a balloon cabin body based on the principle of integration of the electric field sensor and the magnetic field sensor.

The first electric field instrument extension rod 2 and the second electric field instrument extension rod 14 are rotatably connected with the bearing rod upper piston 9, so that the first electric field instrument extension rod 2 and the second electric field instrument extension rod are folded and unfolded; the third electric field instrument extension rod 15 and the fourth electric field instrument extension rod 16 are both elastically connected with the bearing rod lower piston 10, so that the third electric field instrument extension rod 15 and the fourth electric field instrument extension rod 16 can be folded and unfolded.
The detection equipment is made of carbon fiber and non-magnetic materials such as aluminum, copper, titanium and the like.
The platform 4 is provided with a preposed signal processing circuit which is used for being respectively connected with the scalar magnetic field sensor 5, the vector magnetic field sensor 6, the vector pointing position sensor 7 and the four electric field spherical probes 8 and processing signals and data collected by the scalar magnetic field sensor 5, the vector magnetic field sensor 6, the vector pointing position sensor 7 and the four electric field spherical probes 8,
the vector magnetic field sensor 6 and the vector pointing position sensor 7 are rigidly connected and used for calibrating vector magnetic field pointing.
The detection equipment is arranged between the floating air ball 12 and the air ball cabin 13 and is unfolded by depending on the lifting force of the floating air ball 12 and the gravity of the air ball cabin 13.
When the apparatus is used on a floating platform, as shown in figure 3, the detection apparatus is mounted between the balloon chamber 13 and the floating balloon 12 and connected by a cable. The bearing rod upper piston 9 and the bearing rod lower piston 10 which are arranged at the two ends of the bearing rod 1 are respectively connected to the cable and bear the pulling force on the cable when the floating air ball 12 rises; when the floating air ball 12 is placed on the ground, the first electric field instrument extension rod 2, the second electric field instrument extension rod 14, the third electric field instrument extension rod 15 and the fourth electric field instrument extension rod 16 are all under the action of the spring 11 in the bearing rod and are in a folded state; when the floating air ball 12 flies off the ground, the lifting force of the floating air ball 12 is transmitted to the air ball cabin 13 through the force bearing rod 1, the mooring ropes at the two ends of the force bearing rod 1 are acted by force to stretch the spring 11 in the force bearing rod, meanwhile, the first electric field instrument extension rod 2, the second electric field instrument extension rod 14, the third electric field instrument extension rod 15 and the fourth electric field instrument extension rod 16 are all unfolded, and the whole unfolding process is the process of opening the umbrella. When the floating air ball 12 is cut off, and the parachute is not unfolded in the weightless falling stage and finally falls to the ground, the tension on the cable disappears, the spring 11 in the force bearing rod is folded, and the first electric field instrument extension rod 2, the second electric field instrument extension rod 14, the third electric field instrument extension rod 15 and the fourth electric field instrument extension rod 16 are folded again, so that the scalar magnetic field sensor 5, the vector magnetic field sensor 6 and the vector pointing position sensor 7 can be effectively protected from serious damage in the falling to the ground process.
The data collected by the scalar magnetic field sensor 5, the vector magnetic field sensor 6 and the vector pointing position sensor 7 arranged on the magnetometer stretching rod 3 are combined with the electric field data collected by the four electric field spherical probes 8 to be used together to finish the flight calibration correction of the magnetic field data and the electric field. When flying, the floating balloon 12 drives the lower electric and magnetic field detection equipment and the balloon cabin 13 to rotate continuously, so that the directions of the vector electric field and the vector magnetic field detected by the electric and magnetic field detection equipment are changed continuously. After the vector magnetic field rotates by 360 degrees, the linear parameters of the vector magnetic field sensor can be calibrated by utilizing scalar magnetic field data acquired by the scalar magnetic field sensor 6. Meanwhile, the vector pointing position sensor 7 and the vector magnetic field sensor 6 are rigidly and fixedly connected, so that the sensor pointing and space position information at each moment is accurately recorded. The electric and magnetic field detection equipment comprises four electric field spherical probes 8, a scalar magnetic field sensor 5, a vector magnetic field sensor 6 and a vector pointing position sensor 7; the sensor pointing direction refers to the direction of a sensor coordinate system where the vector magnetic field and the vector electric field are located in a geographical coordinate system; the spatial position information refers to the position of the electric and magnetic field detection equipment in the terrestrial coordinate system.
The device comprises four electric field spherical probes 8, a scalar magnetic field sensor 5, a vector magnetic field sensor 6 and a vector pointing position sensor 7, and is used for realizing simultaneous detection of an electric field and a magnetic field based on the floating platform.
The four electric field spherical probes 8 and the vector pointing position sensor 7 are used for calibrating electric field data.
A scalar magnetic field sensor 5 and a vector magnetic field sensor 6 for calibrating the vector magnetic field.
The electric field and magnetic field sensors are deployed far away from the balloon cabin body through the equipment, and meanwhile, the electric field and magnetic field sensors are far away from the influence of electromagnetic interference of other equipment in the balloon cabin 13, so that accurate detection can be realized. Meanwhile, the electric and magnetic field detection equipment detects on the same platform, thereby realizing the same point in space and better analyzing and comparing data.
When the floating air ball 12 takes off, the four electric field ball-type probes 8 are unfolded and folded by using the similar umbrella opening mode realized by the pulling force of the mooring rope.
And a rigid structure is simultaneously and fixedly connected with the scalar magnetic field sensor 5, the vector magnetic field sensor 6, the vector pointing position sensor 7 and the electric field sensor, so that the calibration and correction of the vector magnetic field data and the electric field data in the flight state are realized.
The detection equipment adopts electric and magnetic field detection equipment to be far away from the balloon cabin body 13 and is independent of the platform to carry out simultaneous detection, thereby avoiding the electromagnetic interference of the balloon cabin body, realizing the simultaneous detection of the electric field and the magnetic field in the similar space and approximating to the same point.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited.
