The inverted pendulum of the two-wheeled remote-controlled trolley and its balance control method of the present invention are characterized in that two DC motors (3) are symmetrically fixed on the car body (1), one end of the motor shaft is fixedly connected to the wheel (2), and the other end of the shaft is connected to the wheel (2). The shafts of the code discs (4) are connected; the gyroscope (7) is installed in the middle of the axis of the two wheels and the pendulum (5) is fixed; the controller (11), the remote control receiver (13), the power conversion module (15), the motor The driver (12) is welded on the circuit board (10); the circuit board (10) and the DC power supply (6) are fixed on the vehicle body (1); its balance control method includes automatically judging the zero voltage, correcting its drift, and reducing the measurement noise. to filter. The present invention avoids the control failure of the existing inverted pendulum due to mechanical transmission failure or possible errors caused by the transmission gap; it can walk back and forth, left and right, and remote control on the ground and slopes, can be used for teaching and scientific research, and can more effectively test various pendulums. Pros and cons of control algorithms.

The invention discloses an energy-saving water-saving organic silicon monomer rectifying method which adopts a cis cleavage multi-tower flow. In the rectifying method, the tower top material steam of a high-boiling component removing tower firstly enters a main distribution manifold, then heat is respectively supplied for tower bottom reboilers of a low-boiling component removing tower, a light component removing tower, a hydrogenous tower, an azeotropic tower, a trimethylchlorosilane separating tower, a methyl trichloro silicane separating tower and a dimethyldichlorosilane separating tower through the main distribution manifold, the tower top material steam of the high-boiling component removing tower after heat supply is condensed into liquid, is then cooled to the reflux temperature through an air cooler and enters a tower top reflux tank of the high-boiling component removing tower, a second reboiler is connected with the tower bottom of the dimethyldichlorosilane separating tower, and vapor is adopted for the heat exchange of the reboiler. By adopting the method, because the operating pressure and the operating temperature of the high-boiling component removing tower and themethyl trichloro silicane separating tower with larger cooling quantity requirements are increased, at least two towers in the flow have the condition of adopting air cooling, thereby reducing the circulating water quantity and decreasing the evaporation loss; and the energy-saving water-saving organic silicon monomer rectifying method has strong operation controllability, flexible mode, multiplecontrol means, smaller pressure increasing amplitude and high operation security.

The invention provides an outlet strip steel surface roughness control method suitable for a hot continuous rolling unit. Under the precondition of collecting strip steel characteristic parameters, rolling process parameters and roller use process parameters to calculate the outlet strip steel surface roughness, the method can control the strip steel surface roughness on the work site according to user requirements on the strip surface roughness through reasonable linked setting of the operating surface roughness and the operating surface hardness of working rollers of F6 and F7 frames of the hot continuous rolling unit and the reduction rate between the two frames, so that the benefits are brought to enterprises.
