For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.
[0037] like Figure 1 and Figure 2 As shown, one embodiment of the utility model discloses a nuclear power plant foreign body isolation area equipment control device, which is arranged at the entrance and exit of the nuclear power plant foreign body isolation area (such as the generator foreign body isolation area), and is used for maintenance personnel to control the equipment 2 carried before entering the nuclear power plant foreign body isolation area and after exiting the nuclear power plant foreign body isolation area. The nuclear power plant foreign body isolation area equipment control device includes a cabinet 11, a fixed base 12, a radio frequency reader 13, a visual camera (not shown), an identity acquirer 14, a touch display 15 and a host 16, which are as follows:
[0038] The cabinet 11 includes at least one first storage space 111 for storing the apparatus 2 with the radio frequency tag and at least one second storage space 112, and a shielding structure is provided in the first storage space 111 to shield the external radio frequency electromagnetic signal, mainly to prevent the radio frequency reader 13 from reading the radio frequency tags in other first storage spaces 111. Among them, at least one can be one, two, three or any number.
[0039] The radio frequency reader 13 is used to automatically read the radio frequency tag, and the radio frequency reader 13 is installed in the first storage space 111. The visual camera is used to capture the device 2, and the visual camera is installed in the second storage space 112.
[0040] The fixing base 12 is disposed in the second storage space 112. The fixing base 12 is provided with at least one fixing structure 121 for fixing the tool 2. The tool 2 is fixed by the fixing structure 121, so that the visual camera can stably shoot the tool 2. The at least one can be one, two, three or any number. When multiple fixing structures 121 are included, multiple tools 2 can be evenly fixed on the fixing base 12. Figure 3 shown.
[0041] The identity acquisition device 14 is used to acquire the identity information of the person, and the identity acquisition device 14 is installed on the cabinet 11. The touch display 15 is used to display the information of the person and the appliance 2, and the touch display 15 is installed on the cabinet 11.
[0042] The host 16 is electrically connected to the radio frequency reader 13, the visual camera, the identity acquisition device 14 and the touch display 15, respectively, and the host 16 is installed on the cabinet 11. The host 16 can receive the tool information and personnel information obtained by the radio frequency reader 13, the visual camera and the identity acquisition device 14, and display them through the touch display 15. At the same time, the maintenance personnel can also borrow and return the equipment 2 on the touch display 15. In addition, the host 16 will also count the number of equipment 2, store personnel registration records, store equipment registration records, store borrowing and returning records, etc., to form a log list. It should be noted here that the host 16 has the ability to receive, count, record, store and control, which is realized by using existing technologies. It is a common technical means / common knowledge in this field and will not be described in detail here.
[0043] In this embodiment, the radio frequency tag of the instrument 2 is automatically read and identified by the radio frequency reader 13, and the instrument 2 is photographed and identified by the visual camera, which can maximize the accuracy and reliability of the instrument data in the instrument cabinet, because in actual maintenance activities, many instruments 2 (such as sleeves, measuring instruments, etc.) cannot be bound to radio frequency tags, or binding radio frequency tags will affect the use function of the instrument 2, or introduce new foreign body risks, and the visual camera can use visual methods (such as image recognition, AI recognition, etc.) to photograph and identify the instrument 2. This method does not require any changes to the instrument 2 itself. These two methods will cover most of the needs for self-service management and control of on-site instruments 2, and can also achieve a balance in the size requirements of the instrument cabinet. It should be noted that the radio frequency reader 13 has the ability to automatically read and identify, and the visual camera has the ability to photograph and identify, which is achieved by using existing technologies. It is a common technical means / common knowledge in this field and will not be described in detail here.
