3results about How to "Reduce layout size" patented technology

The invention discloses a gate drive circuit, a display panel and a display device. A level transmission module is used for outputting a level transmission signal, and an output module is used for outputting a gate control signal. A first output unit of the output module is communicated with a current path between a first output end and a first power supply end according to a second clock signal in a first time period, the cascade transmission module receives a starting signal according to the first clock signal in a second time period, and the first time period and the second time period are at least partially overlapped; the level transmission signal is used for sharing the load corresponding to the output end outputting the grid control signal, the requirement for the driving capacity of the output module is reduced, the layout size of the grid driving circuit is reduced, the potential of the first output end can be kept stable in the level change process of the level transmission signal, and the reliability of the grid driving circuit is improved. And the influence of residual charges, electric leakage and other factors on the gate control signal output by the first output end is reduced.

This invention provides a controller signal input circuit, comprising: a signal input terminal for receiving acquired signals, a channel selection circuit module, and a signal processing circuit module; the signal processing circuit module includes a digital signal processing unit and an analog signal processing unit; the channel selection circuit module sends the acquired signal to its first or second channel switching terminal based on the control signal received at its channel control terminal; the digital signal processing unit adjusts the acquired signal input at the first channel switching terminal into a digital input signal adapted to the controller of agricultural machinery and sends it to the controller through its first signal output terminal; the analog signal processing unit adjusts the acquired signal input at the second channel switching terminal into an analog input signal adapted to the controller and sends it to the controller through its second signal output terminal. The technical solution provided by this invention can achieve the acquisition and processing of multiple types of signals through only one signal input terminal, saving resources.

The utility model relates to the technical field of power systems, in particular to a single-bus segmented prefabricated cabin type GIS (gas insulated switchgear). GIS combined electric appliances are arranged in the prefabricated cabin body, two columns of GIS combined electric appliances are arranged, each column is provided with two sets of total combined electric appliances and a plurality of control cabinets, the total combined electric appliances are symmetrically arranged and correspond to one another in position, a first three-station isolation grounding switch is arranged at the upper end of a supporting piece, and the upper end of the first three-station isolation grounding switch is connected with a wire outlet sleeve tee joint through a transposition conductor. One end of the first three-position isolation grounding switch is connected with the current transformer, the current transformer is connected with an interface at the upper end of one side of the circuit breaker, an interface at the lower end of the other side of the circuit breaker is connected with the second three-position isolation grounding switch, and a transposition conductor is arranged on one side of the second three-position isolation grounding switch. Compared with the prior art, the arrangement size of the GIS combined electric appliance is reduced, the equipment cost is reduced, the on-site workload is reduced, transportation is convenient, and prefabricated cabins of different sizes can be adapted more easily.
