使用MSP430F5438单片机和HC-SR04超声波模块，1602显示屏块实现的超声波测距，精确到厘米。(The use of MSP430F5438 microcontroller and HC-SR04 ultrasonic module, ultrasonic ranging 1602 display block realization, accurate to centimeters. )

It is well known that the production of hot coils in uniform thickness depends on various process parameters such as the material, the number of rolling stages, the reduction ratio of the thickness, the rolling speed, the front and back tensions, the friction between the material and rolls, the rolling temperature, and the rolling force at each stage of rolling. In the present study, the effect of front and back tensions on reducing the thickness deviations of hot rolled steel strips were investigated by developing a fuzzy control algorithm. In order to derive the fuzzy control rules, rigid±viscoplastic ® nite element simulations were carried out using the material property determined from the production data.
