The invention provides a surface treatment method and system for strip steel. The method comprises at least comprises the following steps of: 1) pressurizing high-temperature gas and spraying the pressurized high-temperature gas to the surface of strip steel in an incinerator; 3) brushing the surface of the strip steel for a first time; and 3) brushing the surface of the strip steel for a second time. The surface treatment method provided by the invention effectively removes adhesive substances such as rolling oil and iron powder on the surface of the strip steel, and sufficiently utilizes heat of combustion waste gas of the incinerator, so that a great deal of alkali liquor is not used, and therefore, the surface treatment method is energy-saving and environmentally friendly, and is low in production cost.

The invention relates to a method for realizing the gang control of three Z axes in a numerical control machine system, which is based on the principle that when the three Z axes are adjusted to have the same workpiece coordinate, the three Z axes are uniform in motion control for the same workpiece so as to obtain the effect that information calculated from one axis can simultaneously control the three axes, and the motion of the three axes is correct actually. The method comprises the following steps: taking one axis as an effective axis by the system and calculating the motion control information of the Z axis; storing the information whether each Z axis moves or not by the system according to external commands and mutually switching the three Z axes from a motion state to a non-motionstate; sending the motion control information of one Z axis to other Z axes by the system. The control method can effectively control a plurality of Z axes to link together in the batch processing ofa numerical control machine, enhance working efficiency and reduce processing time. The control method is effective and reliable.

The invention discloses an impact-proof buffer release control method and experiment apparatus for a space tether system combination body. The impact-proof buffer release control experiment apparatus comprises a master control computer, a visual sense detection device, an optics identifier, an object emulator, an elastic tether, a tether folding and unfolding apparatus, a task platform emulator and a basic platform. An impact-proof buffer release ground experiment platform capable of simulating a space microgravity environment is designed, and a foundation is laid for verifying effectiveness of proposed control strategies on the ground. The impact-proof buffer control method for the tether system combination body is simple, effective and capable of realizing impact-proof buffer control over the combination body via tension force control over tethers so as to prevent system impact and collision The method is advantaged by simple control, rapid control responses, strong robustness, convenience of engineering implementation and the like. The method is suitable for controlling the space tether system combination body on general occasions. The impact-proof buffer release control method and experiment apparatus can be used for simulating the ground experiment platform in a weightless environment in space, and the platform can be widely applicable and can be used for conducting other relevant space simulation experiments.

The invention discloses a method and a system for controlling a lifter. The method comprises the following steps: a host controller receives control signals sent by an operating board controller, wherein the control signals include handle signals and / or keyboard signals; the host controller judges the control signals and outputs first layer flattening signals to a frequency converter according to a judgment result, wherein the first layer flattening signals comprises automatic layer flattening signals and manual layer flattening signals; the frequency converter outputs a first layer flattening action command according to the received first layer flattening signals, wherein the first layer flattening action command is used for controlling a motor to work. According to the method and the system, the problems that the operation is troublesome, and the structure of a machine is easily damaged because an existing lifter is in shortage of an automatic layer flattening function, and a tractor driver needs to carry out inching adjustment by virtue of a handle in a single manual layer flattening process are solved.

The invention relates to one call telephone sorting and interface method in communication technique field, which realizes user self-definition rules to control calls on base of SIM card, wherein, in the inner structure, user cell phone judges SIM car reset status through interacting platform through cell phone and SIM card; the cell phone sends detail call transfer or forbids interface order content to limit call interface to end; SIM card not sending Send USSD order to cell phone to permit cell phone to indicate user call to end.

The invention relates to an intelligent iris recognition gun cabinet control system, which includes a charging and power supply control module, a main control module, a serial port touch screen, an indicator light and an opening control module, an iris recognition module, and a gun locking mechanism control and acquisition module.
