A safety limit control method for a focus adjustment mechanism, in which a limit switch is installed at the left and right limit positions of at least one stroke interval of the focus adjustment mechanism, and the output ends of all the limit switches are short-circuited to lead out a "limit status feedback" signal , used to drive the GPIO pin of the control system processor and one signal input pin of the dual optocoupler chip; the control system processor receives the "limit status feedback" signal and outputs the "software power-on enable" signal; " Both the "limit status feedback" signal and the "software power-on enable" signal are input to the signal input terminal of the dual-channel optocoupler chip, and are isolated and output by the dual-channel optocoupler chip, and then pulled down to the reference ground of the power supply through a resistor, and then output "Drive circuit power-on enable" signal; when the "drive circuit power-on enable" signal is high level, it provides power to the motor drive circuit; otherwise, cuts off the power supply to realize the safety limit of the focusing mechanism.

The invention provides a mask assembly. The mask assembly comprises a carbon fiber material layer provided with a first hollow region, and a first metal layer which is arranged on the surface of at least one side of the carbon fiber material layer, wherein the first metal layer is provided with a second hollow region corresponding to the first hollow region. The carbon fiber material layer has the characteristics of low expansibility and high strength, so that the influence on the reliability of the mask assembly due to a temperature change in a process is reduced during application of the mask assembly, and a size change, which is caused by the temperature change, of a hollow pattern in the mask assembly is also reduced; meanwhile, the first metal layer enables the mask assembly to have a smooth surface, so that stacking of materials on the surface of the mask assembly in a preparation process of evaporation, sputtering or printing is avoided, and the subsequent scraping procedure for removing the stacked materials and damage caused by the scraping procedure are eliminated; and therefore, the mask assembly simultaneously meets the requirements for high strength and high precision.

The invention belongs to the technical field of charging and replacing of electric vehicles and discloses a battery cabin for a replacing-type electric vehicle. The battery cabin comprises a shell arranged on the middle rear portion of a vehicle body; a downward opening is formed in the shell; an I-shaped space is arranged inside the shell and used for containing a battery box; and the opening is used for allowing the battery box to enter and go out of the shell. The invention further discloses the battery box for the replacing-type electric vehicle and a replacing method of the battery box. The battery cabin is provided with the downward opening used for replacing of the battery box, and thus mounting and replacing are facilitated; telescopic columns are arranged between a left side wall plate and a right side wall plate, the hydraulic telescopic columns are internally provided with electric motors, forward rotation and reverse rotation of hydraulic motors are controlled through a control system of the vehicle body, thus telescopic movement of the telescopic columns is controlled, and locking blocks connected with the telescopic columns are driven to move to clamp and release the battery box; the battery cabin can be arranged on the middle rear portion of the vehicle body so that external impact can be effectively resisted; and in addition, the structure is simple, using is convenient, and high popularization market value is achieved.

The invention relates to a high-power LED face-down chip, formed by P-N electrode extending sheet and silicon substrate with reflective layer, wherein the P-N electrodes have inactivate layer between; the characteristic semi-conductive silicon substrate has electric insulated layer above; the metal reflective layer is above the insulated layer; the P-N electrode extending sheet and the silicon substrate with reflective layer are face-down welded to form high-power LED face-down chip. And its production comprises that: on silicon substrate, using PECVD to deposit one layer of P-N electrode electric insulated layer as SiO2 or Si3N4 insulated layer at 50-100nm thick; then using magnetic-control splash or electron beam to evaporate one layer of metal reflective layer at 200-300nm made from TiAl or TiAg. The invention can improve the lighting efficiency and radiation efficiency.

A heterogeneous controller cluster service active scheduling system and method based on abnormality perception. The system includes a state collection module, a communication agent module, an abnormal state perception module, and a service active scheduling module. The steps of the method are: the communication agent module establishes a connection with the controller and the switch; the state collection module collects the operating environment state parameters and the load state parameters of the controller; The abnormal state sensing module updates the abnormal parameters of the controller; the abnormal state sensing module judges whether the controller is abnormal; the active business scheduling module selects a candidate controller and actively schedules the abnormal controller business. The invention has high universality and independence, and can timely and accurately discover and actively schedule its business when the controller in the heterogeneous controller cluster is abnormal.
