Description

Technical Field

[0001] This invention relates to the technical field of nuclear power communication, and more particularly to a monitoring and intercom system for gates in nuclear power plants. Background Technology

[0002] The architectural structure of the biosafety door entrance is derived from the emergency command center of a special industrial building in a nuclear power plant. It is applicable to the emergency command center of nuclear power plants and nuclear facilities, as well as other biosafety door entrances that need to meet the requirements of the corresponding three working conditions.

[0003] Current technology allows for communication via an external telephone system when personnel gates and emergency gates are closed. However, in practical applications, telephones using analog or digital signals (low voltage) are susceptible to external electromagnetic interference, resulting in poor call quality, low volume, and background noise.

[0004] Currently available technology lacks a monitoring system; instead, there are viewing windows on the gate panels. These windows are small and have blind spots, making it impossible to observe the situation on the personnel gates or emergency gate panels. Summary of the Invention

[0005] In response to the technical problems mentioned in the background section, this invention provides a monitoring and intercom system for gates used in nuclear power plants. The invention primarily utilizes cameras to monitor the internal status of personnel gates and emergency gates; the intercom system allows for communication without the aid of other external devices, enabling communication outside the containment vessel, inside the gates, and inside the containment vessel.

[0006] The technical means employed in this invention are as follows:

[0007] A monitoring and intercom system for gates in a nuclear power plant includes: an electrical control cabinet; and also includes: a switch, a powerline adapter, an industrial socket, a hard disk recorder, a touch screen display, an IP intercom, a PoE switch, a camera, and a PoE power supply.

[0008] The switch, powerline adapter, industrial socket, and hard disk burner are installed inside the electrical control cabinet; the touch screen display is installed on the outer shell of the electrical control cabinet; the electrical control cabinet is also installed outside the safety enclosure; the IP walkie-talkie is installed outside the safety enclosure.

[0009] The powerline adapter is connected to the switch, the switch is then connected to the hard disk burner, and the hard disk burner is connected to the touch screen display.

[0010] The switch is also connected to the POE power supply (9) and the IP walkie-talkie;

[0011] The industrial socket is connected to the PoE switch via an electrical penetration component; the PoE switch is connected to the camera; and the PoE power supply is connected to the industrial socket via an electrical penetration component.

[0012] Furthermore, there are two cameras; the cameras are bullet cameras; and the cameras are respectively located near the entrance.

[0013] Furthermore, the PoE switch is located inside the gate.

[0014] Furthermore, the powerline adapter enables the conversion between network signals and powerline carrier signals.

[0015] Furthermore, the hard disk burner is used to store network video signals captured from the camera.

[0016] Furthermore, the information collected by the camera is transmitted to the hard disk burner via a local area network interface, and then the hard disk burner transmits the video signal to the monitor via an HDMI interface to display the monitoring screen.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This utility model system enables communication between three locations: personnel gate, emergency gate, inside the safety enclosure, inside the gate, and outside the safety enclosure. The communication signal is strong, the anti-interference capability is strong, and it does not interfere with the external telephone system. Even if the external telephone is damaged, communication can still be carried out via IP walkie-talkie.

[0019] The system of this utility model features a one-button call function on the IP walkie-talkie, which is easy to operate and has a loud call volume that can alert people in the vicinity to answer.

[0020] This utility model system can monitor the operation process of key internal components of personnel gates and emergency gates, and can help maintenance personnel troubleshoot problems by viewing the monitoring screen when the gate malfunctions.

[0021] By adding a powerline adapter, this system allows for the convenient addition of other external Ethernet communication devices within the containment or gate, facilitating the expansion and addition of other functions. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0031] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0032] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
