A four-degree-of-freedom parallel mechanism with a large-angle twistable moving platform and a composite branch chain. It includes a fixed platform, a moving platform, a first branch chain, a second branch chain and a third branch chain, and has two degrees of freedom in translation and rotation. Advantages of the present invention: First, the configuration mode of the composite branch chain of the lead screw and the electric push rod is adopted, while ensuring that the required degree of freedom of the mechanism is satisfied, the number of branch chains of the mechanism is reduced, and the distance between the branch chains is reduced. Interfere with each other and increase the working space of the organization. Secondly, the movable platform structure with hollow in the middle is adopted, and with the double rotating accessories on the movable platform, under the mutual movement of each branch chain, the movable platform can be twisted at a large angle of more than 180 degrees. Finally, there are two branched chains with the same structure and simple structure, which reduces the difficulty of manufacturing and processing and saves the manufacturing cost.

A parallel mechanism with composite sliding telescopic rods. It includes a fixed platform, a moving platform, a first branch chain, a second branch chain, a third branch chain and a fourth branch chain, and has three translational and two rotational degrees of freedom. The invention has the advantages: on the one hand, the use of compound sliding telescopic rod branches reduces the number of branch chains of the mechanism and reduces interference, thereby increasing the flexibility of the mechanism and expanding the working space of the mechanism, so that the mechanism can complete the expansion and contraction relative to a single mechanism. The movement of the rod mechanism is more complex; on the other hand, the use of three sliding telescopic rod branches with the same structure can increase the transmission efficiency of the mechanism in the vertical direction, and the structure is simple, the assembly is simple, and the difficulty of manufacturing and processing is reduced. The present invention is suitable for processing environments that require multiple degrees of freedom and high flexibility, such as parts processing and assembly.

The present invention provides a method and device for configuring a web request. The method includes obtaining the web request, identifying whether the web request uses the default protocol, and if not, configuring the current request according to the set format. When the system is compiled and packaged, the configuration file Perform a read operation, write the read data into the given directory of the corresponding project; deploy the system installation to the server, start the web container service; when logging in on the web side, search for the configuration file in the given directory of the project, and perform file configuration Read operation, initialize the file data into the memory, define a hash table for storage; monitor the web request initiated by the client, judge the protocol type, and forward the request according to the protocol type. The invention only needs to maintain a set of system codes to meet the customized needs of different customers, reduce the number of code branches and the development cost of the company's maintenance personnel, and in the development process, it can complete the rapid adaptation process according to the manufacturer's needs, improving the work efficiency.

The invention relates to a method for controlling extension of lateral branches of cut chrysanthemum. The method is that before axillary buds of the cut chrysanthemum are not fully extended, a light density ratio of red light to far red light in an illumination environment is adjusted to (0.05-0.80):1, and the above ratio is kept until the cut chrysanthemum firstly blooms. According to the methodprovided by the invention, a light quality ratio is adjusted by a physical method, synthesis and signal transduction of main hormones regulating and controlling branching in chrysanthemum plants are changed, so that expression of related genes controlling the extension of the lateral branches is changed, especially expression of a key integration factor DgBRC1 controlling dormancy and extension ofthe lateral branches is changed, and finally the extension of the lateral branches of the chrysanthemum is affected; and the method effectively solves the prominent problem that artificial and continuous bud picking is needed because the lateral branches are too long and too more in the production process of the cut chrysanthemum, greatly saves labor costs, is simple and easy to implement, has high practicability and is easy to promote.
