The invention relates to the technical field of lithium battery replacement, and discloses a maintenance protection method and management system for a lithium battery replacement cabinet, and the method comprises the following steps: S100, creating an operation and maintenance account number through a front-end business management system, and distributing a corresponding electric cabinet management authority for the operation and maintenance account number; s200, the operation and maintenance personnel log in a front-end electric cabinet management applet through the operation and maintenance account; s300, entering a management interface of the battery changing cabinet, and issuing an unlocking instruction; s400, the electric cabinet terminal performs legality verification on the unlocking instruction through an agreed verification algorithm; and S500, after the verification of the electromagnetic lock is passed, unlocking operation is executed. According to the invention, a double-layer authority control mechanism is constructed through a front-end service management system, an electromagnetic lock is configured in a maintenance bin of the battery replacement cabinet, and a system instruction is used for replacing a traditional key / password control maintenance bin switch mode, so that dynamic safety protection of lithium battery assets of the battery replacement cabinet is realized; the risk of asset loss caused by the fact that a traditional lock cannot update management and control measures in time is solved.

The utility model provides a low flatbed semitrailer convenient to install and fix, which belongs to the technical field of semitrailers, and comprises a semitrailer body, the semitrailer body is divided into a loading part and a hooking part, a base and an alignment assembly are arranged below the hooking part, and the alignment assembly is connected with the loading part. The alignment assembly comprises a first fixing plate and a second fixing plate which are symmetrically and fixedly connected to the upper surface of the base, the side wall of the first fixing plate is rotationally connected with a threaded rod through a bearing, and the threaded rod is rotationally connected to the side wall of the second fixing plate in a penetrating mode through a bearing. According to the utility model, the orientation position of the low flatbed semitrailer is finely adjusted by arranging the alignment assembly, so that the tedious control of a tractor by a worker can be avoided, the installation efficiency is higher, and meanwhile, the installation and hooking of the tractor are more convenient by arranging the supporting assembly and matching with the alignment assembly.

The invention discloses a method and a system for improving lottery sales rewarding safety based on encryption processing, and relates to the technical field of bill verification. The method comprises the following steps: based on a lottery sale terminal, obtaining a transaction timestamp of current lottery purchase, a sale terminal mark, a position code identifier and lottery type information, encoding parameters, performing encryption processing, constructing a unique dynamic encryption identifier of a lottery, and obtaining encrypted bill information. According to the method, the corresponding dynamic encryption identifier is created for each transaction by using the transaction timestamp, the point-of-sale terminal identifier and the position code identifier, so that the anti-counterfeiting capability of the bill is improved, and the judgment accuracy of the authenticity of the lottery ticket is improved by comparing the pre-stored information stored in the database with the data collected by the prize claiming terminal in the prize claiming stage; in combination with a biological recognition technology, the consistency of a prize claiming person and a ticket buyer is ensured, and the occurrence of manipulation and fraud behaviors is prevented through continuous tracking and deviation analysis of the prize winning probability of the user.

This invention relates to a method and related apparatus for transmitting data from an actuator to a control device. Specifically, this invention relates to a method for transmitting data from an actuator (2) to a control device (1) that operates the actuator (2), wherein the control device (1) operates a piezoelectric element (3) contained in the actuator (2), wherein, for transmitting data in the actuator (2), a load (7) is connected in parallel with or not in parallel with the piezoelectric element (3).

The invention discloses a multifunctional clamp for cylinder support machining, and relates to the technical field of cylinder support machining, the multifunctional clamp comprises a supporting frame and a cylinder, one side of the supporting frame is provided with a driving assembly used for controlling the angle of the clamp, and the driving assembly comprises a hydraulic rod, an adapter block, a rack, a driving gear, a threaded rod and a tooth block. According to the multifunctional clamp for machining the air cylinder support, through the design of a hydraulic rod, an adapter block and a rack can be driven to move up and down, the rack is meshed with a driving gear, so that the driving gear rotates due to position movement of the rack, the driving gear is connected with a threaded rod, and the threaded rod is in threaded connection with the interior of a supporting frame; therefore, the driving gear and the threaded rod synchronously rotate to drive the tooth block to move back and forth in the built-in groove, the corresponding moving position of the tooth block can be quantitatively controlled according to installation of the driving gear and the threaded rod, and a user is prevented from manually controlling the moving position of the tooth block one by one.
