Description

Technical area

The invention relates to a human-machine interface, in particular a human-machine interface device for an AC/DC power supply or controller.

State of the art

With industrial automation, the human-machine interface is widely applied to many devices and machines. Human-machine interface (HMI) is also called operator interface (OI). Their main function is to provide an interface between humans and machines. It can display the system's process or setting status, alarm, lockout and other relevant information in text, numbers or graphics.

The human-machine interface can not only use buttons, switches and indicator lights of different colors, sizes and appearances to operate the equipment and display the operating status such as power on and off, but also provide additional explanations through a display (flat panel) to help the operator better understand the required state of the equipment or the information can be sent to the operator for reference. The most commonly used display type at present is liquid crystal display (LCD). This integrates the above buttons, switches, indicator lights or display into a human-machine interface module.

When the human-machine interface is used in devices with a small panel, such as: B. an AC/DC power supply or a controller with a height unit (1 U), especially if the area of the air inlet holes is to be maximized, the usable area for the human-machine interface is reduced. When designing the human-machine interface, the task is always to achieve a high level of clarity, readability and identifiability within the limited screen space.

For this reason, the inventor developed this invention based on his many years of research and development experience in related technical areas.

Task of the invention

The object of the invention is to provide a human-machine interface device for AC/DC power supply or controller which has a small area screen and has the advantages of a clear, easy to read and easy to identify display.

This object is achieved by the human-machine interface device for AC/DC power supply or controller, comprising: a human-machine interface module to be mounted on the panel of an AC/DC power supply or a controller; and a cover layer arranged on the front of the human-machine interface module and capable of sticking on the panel of the AC/DC power supply or the controller, wherein the cover layer has a transparent viewing window, wherein the liquid crystal display panel is located exactly in the position of the viewing window, wherein the cover layer is provided with a state display area on the outside adjacent to the viewing window, and wherein a plurality of different state information is displayed in the state display area, whereby when the liquid crystal display panel displays the current state, a light spot is generated on the liquid crystal display panel at the location of the corresponding state information, so that the user can read the current state information directly through the position of the light spot.

The light spot 112 also consists of a large number of pixels. The user can use the position of the light spot 112 to quickly read the information that there is a constant current (CC) in the current state.

It should be noted that the liquid crystal display 11 can also display a light spot when the user selects remote control or lockout so that the user can read the status of remote control (REM) or lockout. In addition, if a machine malfunction occurs, the user can also read the ERR (error) status via the light point display, so that he can carry out troubleshooting as quickly as possible.

As can be seen from the above description, the invention not only integrates the display screen, buttons, knobs, etc. of the human-machine interface into the human-machine interface module, but also utilizes the design of the status display area, thereby displaying on the liquid crystal display the for the Pixels used for status information can be saved and multiple pixels can be provided for displaying voltage, current and other data. Therefore, a clear, easy to read and easily identifiable display can be achieved within a limited screen area.

In summary, this invention is extremely practical compared to similar products. At the same time, after searching for technical information on this type of structure at home and abroad, no similar structure was found in the literature. Therefore, this invention actually meets the requirements for a utility model and an application must be filed in accordance with the law.
