Abstract: A method and for filtering broadcast data, which is applied to a gateway and includes steps of: obtaining a current broadcast message broadcast by a piece of terminal equipment; determining signature information of current broadcast data in the current broadcast message; comparing the signature information corresponding to the current broadcast message with signature information corresponding to various valid broadcast messages received by the gateway to determine whether a first valid broadcast message being the same as the current broadcast message is presented in the various valid broadcast messages. If the first valid broadcast message is presented, the current broadcast message is determined to be a duplicate broadcast message, and the current broadcast message is discarded; if the first valid broadcast message is not presented, the current broadcast message is determined to be a newly-received valid broadcast message.

Abstract: The present disclosure discloses a multistage electric cylinder. The multistage electric cylinder includes a cylinder barrel, a linear motion component. The linear motion component is axially movable in the cylinder barrel and includes a first screw rod; a second screw rod which is sleeved on the first screw rod; a screw rod nut which is installed on the second screw rod; an immovable tube which is coaxially fitted on an outer side of the first screw rod and an outer side of screw rod nut; a first protective tube which is coaxially fitted on an outer side of the immovable tube and moves along an axial direction of the immovable tube; and a second protective tube which is coaxially fitted on an outer side of the first protective tube and moves along an axial direction of the first protective tube.

Abstract: The present disclosure is related to an electric cylinder with a buffering device. The electric cylinder includes a cylinder barrel, a linear motion component and a buffering device. The linear motion component is axially movable in the cylinder barrel. A load end of the linear motion component is connected to a load, and a power end of the linear motion component is connected to a power source. The buffering device is provided close to at least one of the load end of the linear motion component or the power end of the linear motion component, so as to provide buffering for the at least one of the load end or the power end.

Abstract: The present invention discloses a method of reducing octane loss in catalytic cracking of gasoline in S-Zorb plant. The method comprises following steps: a. Collecting equipment data and adjusting differences thereamong to construct initial data sample set; b. Collating data sample set; c. Employing local linear embedding to reduce dimension of independent variables, and trimming the independent variables to obtain reserved independent variables; d. Calculating correlation coefficients of the reserved independent variables and removing variables with too high correlation coefficients to obtain main variables; e. Constructing a BP neural network model of the main variables to obtain optimal octane loss prediction model; f. Employing the optimal octane loss prediction model to obtain a predicted optimal operating condition for each main variable. The present invention has advantage of reducing octane loss and improving quality of refined oil.
