As shown in fig. 1, 2, a levelling device that geodesic platform was used is measured on ground, including base 2, DC power supply 8, 2 lower extremes of base are equipped with lower margin 1, 2 upper end equipartitions of base have 3 leveling mechanism 3, 3 leveling mechanism 3's upper end all is connected with last mounting panel 4, inclination sensor 5 is installed to the upper end of going up mounting panel 4, inclination sensor 5 is connected with leveling control panel 7 through gravimeter 6, leveling mechanism 3 is including fixing leveling motor 31 on base 2, and leveling motor 31's output is connected with last mounting panel 4, leveling motor 31 is connected with leveling control panel 7 through motor drive module 9, DC power supply 8 is connected with leveling control panel 7.
A DC-DC conversion module is arranged in the leveling control board 7, and the leveling control board 7 is also provided with 2 RS422 serial ports, 2 RS232 serial ports, 2 CAN interfaces and 1 Ethernet interface.
In the utility model, the base 2 is used for supporting the leveling platform and meeting the installation requirement of the leveling platform on a carrier; the leveling mechanism 3 is used for quickly leveling the upper mounting plate 4 and the load according to the instruction information; the inclination angle sensor 5 is used for measuring the inclination angle of the load and used as the input of the leveling control board, and the upper mounting plate 4 is used for mounting the load and the inclination angle sensor 5.
When the method is implemented specifically, the platform is manually adjusted to be approximately horizontal (within +/-3 degrees) by using the ground feet 1, the self-checking is carried out after the system is electrified and started, and whether the leveling control pulse of the gravimeter is received or not is judged after the detection that each unit of the system is normal. And leveling according to the leveling control pulse after receiving the pulse signal. If the gravity meter leveling control pulse is not received, continuously judging whether an external leveling instruction is received, and if the external leveling instruction is not received, continuously waiting; if an external leveling instruction is received, the inclination angle in the horizontal direction is measured X, Y in real time according to the inclination angle sensor, and due to the fact that the inertia of the supporting platform is large, when the supporting legs move downwards, a large inertia force is generated, and the supporting platform shakes. When leveling by a gradual height method, the supporting legs move upwards, the acceleration is small, the inertia force is small, and the whole leveling process is stable. Therefore, a stepwise approach is adopted.
The control signal flow in the utility model is as follows: the inclination angle sensor sends inclination angle information in two directions of the level X, Y to the leveling control board in real time, after the control board collects the inclination angle information, three motor control signals are calculated through a leveling algorithm, meanwhile, the inclination angle sensor sends level monitoring information to the gravimeter system and receives control pulse signals sent by the gravimeter system; the motor driving module converts the control signal output by the control panel into a motor driving signal.

e) two RS422 serial ports and two RS232 serial ports are configured;
f) two CAN interfaces are configured;
g) configuring an Ethernet interface;
the external power supply of the utility model adopts DC24V to supply power, 24V simultaneously supplies power to the control panel and the driving module, and the internal power supply of the control panel and the power supply required by the tilt sensor are generated in the control panel through the DC-DC conversion module.
When the three-axis support rapid leveling platform device is applied, a control circuit and a control algorithm scheme are mainly adopted for carrying out:
1) a control circuit: the control circuit is a functional block diagram, as shown in fig. 3. The system signal flow is as follows: the tilt angle sensor sends tilt angle information of the horizontal X, Y direction to the control panel in real time; after the control panel collects the inclination angle information, three motor control signals are calculated through a leveling algorithm, meanwhile, horizontal monitoring information is sent to a gravimeter system, and a control pulse signal sent by the gravimeter system is received; the motor driving module converts the control signal output by the control panel into a motor driving signal.
2) And (3) a control algorithm: the leveling system adopting the position error leveling control method is complex and high in cost, but the leveling speed is high and the leveling precision is high. A, B, C in FIG. 4 represents a three-leg fulcrum, α and β are the tilt angles measured by the tilt angle sensor, and the distance between CDs is L1, and the distance between DB is L2. The amount of extension and retraction of each leg can be listed as shown in the attached table 1.
