Ant-colony calibrating precise force-measuring walking aid device

The invention relates to the field of rehabilitation training, and aims to provide a device which can be used for the calibration of a precise force-measuring system of a walker. Compared with conventional linear calibration methods, the device can effectively reduce cross interference errors and improve the measuring precision of a bearing force of the walker. For fulfilling the aims, the invention adopts the technical scheme that: an ant-colony calibrating precise force-measuring walking aid device comprises a walker bracket, a strain foil bridge network, an amplifier for a linear meter, a second-order low-pass filter, a singlechip, another singlechip, another wireless transceiver chip and a computer, wherein the another singlechip and the another wireless transceiver chip are combined for receiving wireless signals and transmitting the received signals to the computer; and the computer performs the ant-colony algorithm-based static calibration of the force measuring system of the walker. The walking aid device is mainly applied to the parameter estimation of linear frequency modulated signals during digital signal processing.
