The invention provides a lifting platform, a constant-speed lifting method for the lifting platform, and a computer readable storage medium. The constant-speed lifting method comprises n stepping processes, and the stepping distances and the stepping speeds of the stepping processes are the same; the number of revolutions of a motor used for driving the lifting platform to rise and fall is Pn, andthe speed is VPn; Pn = i * Sn/k, and Vpn = i * Sn/kt, wherein the motor and the lifting platform are linked through a lead screw; i is the reduction ratio of the lead screw to the motor, k is the lead of the lead screw; and Sn is the stepping displacement of a nut on the lead screw in the nth step. According to the lifting platform and the constant-speed lifting method, uniform lifting speed is kept at any position within the full-stroke range, the speed can be steplessly controlled, and lifting is gentle; meanwhile, the lifting positioning time can be shortened, the overall lifting period can be prolonged, and the lifting platform is applied to electronic computed tomography equipment; and the safety and comfort of a patient can be greatly improved on the premise that the high scanning diagnosis efficiency is guaranteed.

    本发明提供了一种升降平台、用于该升降平台的匀速升降方法及计算机可读存储介质,包括n个步进过程,每个所述步进过程的步进距离和步进速度相同;用于驱动所述升降平台升降的电机在第n步的转动圈数为Pn、转动速度为VPn,Pn=i×Sn/k,Vpn=i×Sn/kt,其中,所述电机与所述升降平台之间通过丝杠连动,i为所述丝杠到所述电机的减速比,k为所述丝杠的导程,Sn为所述丝杠上的丝母在第n步的步进位移。本发明在全行程范围内的任意位置保持均匀的升降速度,且速度大小可无极控制,升降平缓;同时可以减少升降摆位时间,提高整体升降周期,应用于电子计算机断层扫描设备,可在保证较高的扫描诊断效率的前提下,极大改善患者安全感,舒适感。
