The invention belongs to the technical field of gas separation, and particularly relates to a dynamic control purification system and method for multi-process source hydrogen, and the system comprises a mixing and pretreatment unit, a multi-tower PSA separation unit, a product and waste gas collection unit and a control and execution unit; the mixing and pretreatment unit comprises a gas mixer, a preheater and a deaerator which are connected in sequence; the multi-tower PSA separation unit is connected between the mixing and pretreatment unit and the product and waste gas collection unit through a pipeline, and the multi-tower PSA separation unit at least comprises four adsorption towers which are connected in parallel; the control and execution unit comprises a control module, a first online analyzer and a second online analyzer. Compared with the prior art, the problem that in the prior art, operation of a fixed time sequence program cannot effectively cope with impurity fluctuation existing in hydrogen of a mixed source is solved. According to the scheme, on the basis of dynamic regulation and control of the impurity concentration, tiny fluctuation of the product purity is maintained under large feeding concentration fluctuation, and qualified output of the product is guaranteed.

The application provides a cable GIS terminal type test device to construct a mechatronic test platform integrating self-shielding environment simulation, multi-posture working condition reproduction, self-adaptive electrical connection and built-in nondestructive testing. The device itself forms a Faraday cage effect by the metal cabin to replace a special shielding hall. The posture driving mechanism is used to realize safe switching of the terminal between horizontal and vertical working conditions. Through the sensor and self-adaptive electrical connection assembly, the comprehensive solution of efficiently and accurately completing the full item type test of the cable GIS terminal in the ordinary environment is realized.

This invention relates to a handle structure and an automotive window. The handle structure includes a safety component, a handle, and a locking component. The mounting component includes a corresponding mounting base and a handle stop. The handle includes a connected limiting section and a rotating section. The rotating section is rotatably mounted on the mounting base and has two mating parts spaced apart along the rotation direction. When the limiting section rotates with the rotating section, it has a window-locking position blocked by the handle stop and an window-opening position that avoids the handle stop. The locking component includes a locking member, which is movably mounted on the mounting base and corresponds to the mating parts, so that when the limiting section rotates to the window-locking position and the window-opening position, it can approach and move away from the adjacent mating parts. In this solution, the handle can be stably locked when the window is in the open or closed position, allowing the window to switch safely and quickly between the open and closed positions, effectively ensuring safety and providing simple and convenient operation.

This invention discloses a cholesteric liquid crystal display device and its driving method, belonging to the field of display technology. The device integrates a source switching module and an external driving module on a first substrate, respectively connected to the data leads of the driving chip, the external power supply, and the internal data lines. The driving method is executed by a timing control module. First, the external driving module is turned on to initialize the screen using an external high-voltage signal. Then, the system switches to the source switching module, using the low-voltage data signal from the driving chip and writing the image via time-division multiplexing. Finally, the display can be maintained by simultaneously turning off both modules to make the pixels float. This invention achieves safe switching of the driving source through structural innovation, effectively reducing the performance requirements of the driving chip, avoiding current backflow, and significantly reducing the number of chips used.
