  "textContent": "The invention relates to the field of height measurement, disclosing a method and a device for improving the stability of height difference measurement based on a corrugated tube. The method comprises: improving the structural stability of a height difference measuring device between a first pressure sensor and a second pressure sensor, obtaining the structural stability improvement result; collecting a first pressure from the first pressure sensor, detecting whether the first pressure is affected by external interference; when the first pressure is not affected by external interference, performing pressure screening on the first pressure to obtain a screening pressure, and calculating a first pressure average value of the screening pressure; collecting a second pressure from the second pressure sensor, calculating a second pressure average value of the second pressure; based on a historical pressure average value of the second pressure sensor, detecting the pressure accuracy of the second pressure average value; when the pressure accuracy is accurate, updating the second pressure by utilizing the second pressure average value to obtain an updated pressure; calculating the dynamic height difference of the height difference measuring device, utilizing the dynamic height difference to determine a dynamic stability improvement result of the height difference measuring device. The invention can ensure the stability of pressure measurement.",
