Problems solved by technology
[0004] This inclined posture will cause the vibration isolation platform to gradually shift, and the shift will accumulate positively. The more times of inflation, the greater the shift
In the end, the air floating platform cannot be used, and manual correction is required, resulting in economic costs and time costs

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the drawings. Those skilled in the art will understand that the embodiments are intended to help the skilled person to clearly understand the present invention, and are not intended to limit the present invention.
[0034] Such as Figure 1-2 As shown, the present invention provides a height leveling control system for an air spring vibration isolation platform, including:
[0035] There are at least three height valves G1, G2, G3. The height valve is located on the slow inflation path of the air spring isolation platform 10, and each height valve is correspondingly arranged on a set of air springs. The height valve G1 corresponds to the air spring A10. Valve G2 corresponds to air spring A 20, height valve G3 corresponds to air spring A30. The height valve is used in slow charging mode to control the height of the corresponding positions of the three sets of air springs. When the inflation reaches the...

The invention provides a height leveling control system for an air spring vibration isolation platform. The system comprises at least three height valves, at least three height sensors, a pressure sensor, an analog quantity input module, a processor and a digital quantity output module, wherein the height valves are used for adjusting the height of the vibration isolation platform on the corresponding position, the height sensors are arranged on the air spring vibration isolation platform and are used for detecting the height data of the corresponding positions, the pressure sensor is used fordetecting the pressure data of an air spring, the analog quantity input module is connected to the pressure sensor and the height sensors and is used for acquiring the corresponding pressure data andheight data, the processor is used for receiving the analog quantity data of the analog quantity input module and processing and converting the analog quantity data into the digital quantity data, the processor comprises a height tracking and leveling control module, the digital quantity output module is used for receiving the digital quantity data of the processor and controlling the on-off states of electromagnetic valves arranged on slow air inflation pipeline and rapid air inflation pipeline, and therefore height leveling of the air spring vibration isolation platform can be realized.
Description
Technical field [0001] The invention relates to the technical field of an air spring vibration isolation platform, in particular to a height leveling control system and method of an air spring vibration isolation platform. Background technique [0002] At present, the air spring vibration isolation platform usually adopts the method of installing a height valve on the air path for leveling. For example, the air spring is divided into three groups, and each group is equipped with a height valve, and the air spring is isolated from vibration according to three points to determine a plane. The platform is leveled. [0003] However, in practice, it has been found that during the floating process of the above-mentioned type of vibration isolation platform, due to uneven load and different air pipe lengths, a group of air springs must first float to the highest point, and then The second and third groups of air springs will gradually float, and eventually reach the same height at three ...
