The invention discloses a device and method for checking an electric transformer based on a virtual instrument. The device comprises a virtual instrument platform (1) composed of a computer. The virtual instrument platform is in wired or wireless connection with a signal acquisition host (2). A standard signal acquisition card (3) and an acquisition card (4) for signals to be measured are inserted into the signal acquisition host, the input end of the standard signal acquisition card is connected with output signals of a precision transformer, and the input end of the acquisition card for signals to be measured is connected with output signals of the transformer to be measured. According to the device and method for checking the electric transformer based on the virtual instrument, checking of the electric transformer is completed through the combination of the virtual instrument developed in a computer and a universal analog signal acquisition device, and the effect is as good as that of a traditional instrument. Furthermore, the functions of high-precision data computation, display, storage and the like can be achieved by utilizing vast software resources and hardware resources of the computer based on the virtual instrument technology. Due to the adoption of the virtual instrument, a hardware circuit is simpler in logic, and it is only required that modules are simply connected with each other.

The invention relates to the field of automatic processing applicable to L valve stems, in particular to a directional transmission method and device applicable to L valve stems. The directional transmission device applicable to the L valve stem sets the movement mode of the hopper, adding torsional motion to the vibration or up and down movement of the traditional hopper. The spiral trough rises, and the L valve stem and the disc make an upward torsional movement. When the vertical component of the inertial force on the L valve stem is greater than the acceleration of gravity, the L valve stem jumps upward along the spiral groove of the disk; when the vertical component is less than When gravity is accelerated, the L valve stem overcomes the friction force and slides upwards along the spiral groove. This movement makes the L valve stem jump upwards along the spiral groove of the disc and the L valve stem overcomes the friction force and slides upwards along the spiral groove. Feed trough to complete the automatic orientation of the L valve stem.

The embodiment of the invention discloses a collision recognition method, device, equipment and storage medium. Wherein, the method includes: if it is detected that the motion state of the moving object has a sudden change according to the speed information of the moving object, then determining the sudden change speed, the sudden change acceleration and the sudden change time; according to the sudden change speed, the sudden change acceleration, the collision speed threshold and the collision acceleration threshold, Determine whether the moving object collides; if a collision occurs, determine the duration of the collision according to the speed change information after the mutation time, and determine the collision degree of the moving object according to the duration of the collision. The embodiment of the present invention determines whether the moving object collides by acquiring the sudden change velocity of the moving object, and determines the collision degree of the moving object according to the speed change information after the collision, reduces the hardware equipment for obtaining acceleration information, reduces the requirements for hardware, and realizes The precise judgment of the collision degree improves the handling efficiency of collision accidents.

The technical solution of the present invention includes an Activiti-based process and form interaction method and system, which are used to realize: create and deploy a process model; start the process and generate a process instance, and obtain the process of one or more nodes of the process instance based on the process variable rules Variable value; after the task is completed, pass the process variable and its corresponding value to the current and / or future running process through the interactive interface, so as to control the current and / or future running process flow or task executor.

The present application discloses a method and a device for offloading a memory exhaustion processing flow to user space. A specific implementation of the method includes: when a process triggers a memory exhaustion event, writing the relevant information of the memory exhaustion event into a memory page shared by the user space and the kernel space; the memory exhaustion service of the user space The process obtains the relevant information of the memory exhaustion event through the memory page; the memory exhaustion service process of the user space uses the relevant information of the memory exhaustion event to process the memory exhaustion event. This implementation method realizes offloading the memory exhaustion processing in the kernel state to the user state for execution, and handing over the entire memory exhaustion processing process to a user state process to complete, reducing the complexity of memory exhaustion processing execution and making it easy to run out of memory Adjustment of processing strategies and upgrade and replacement of business.
