Electric telescopic rod's traction force intelligent control device and method

Abstract

The invention proposes an electric telescopic rod's traction force intelligent control device, comprising a single-chip microcomputer, an input module, a control module, a digital display table, a transmitter and a pull force sensor. The pull force sensor measures the traction force produced from the motion of the electric telescopic rod and develops a simulated voltage signal. The transmitter converts the simulated voltage signal from the [miu]V grade small signal to the standard mA grade simulation current signal. The digital display table converts the standard mA grade simulation current signal into a digital signal. The single-chip microcomputer obtains the magnitude of the pull force of the input module set by the user, compares the magnitude of the pull force by the user with the traction force of the electric telescopic rod converted from the digital signal, and based on the comparison result, outputs corresponding electric level signal combination. The control module obtains the current electric level signal combination of the single-chip microcomputer, and based on the current electric level signal combination, controls the electric telescopic rod to extend or shorten or stay unchanged. According to the embodiments of the invention, it is possible to realize the intelligent control over the magnitude of the traction force of an electric telescopic rod of a tractor in a simple and convenient manner.
