Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant equipment technology, and in particular to a wireless module charging cabinet for an electronic dosimeter. Background Technology

[0002] In the production process of nuclear power plants, electronic dosimeters worn when entering and exiting controlled areas are an important instrument in the field of radiation protection. With the increasing requirements for real-time dose data transmission in radiation protection management, electronic dosimeters have been modified to include wireless modules (for transmitting dose data). Currently, some nuclear power plants use automated sampling dispensing cabinets to automatically dispense electronic dosimeters, but these traditional automated dispensing cabinets cannot charge the wireless modules. This forces staff to periodically retrieve the wireless modules, charge them in the laboratory using chargers, and then return them to the field for use. This heavily relies on manual operation and time windows, and coupled with insufficient charging equipment and low charging efficiency, ultimately results in a very inefficient process.

[0038] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] In the following description, it should be understood that the orientations or positional relationships indicated by terms such as "front," "rear," "up," "down," "left," "right," "longitudinal," "horizontal," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail" are based on the orientations or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific orientation. They are only for the convenience of describing this technical solution and do not indicate that the device or component referred to must have a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Figure 1 This is a schematic diagram of the wireless module charging cabinet for electronic dosimeters in some embodiments of this utility model. The wireless module charging cabinet can simultaneously charge the wireless modules of multiple electronic dosimeters.

[0041] Please see Figure 1 The wireless module charging cabinet includes a cabinet body 1, which contains a first receiving space 11 and a second receiving space 12. Specifically, the cabinet body 1 includes a cavity, and a partition plate 13 is provided inside the cavity to separate the cavity. Under the action of the partition plate 13, the first receiving space 11 and the second receiving space 12 are formed. Among them, the second receiving space 12 contains a plurality of mutually isolated charging base chambers 121. Since the wireless module contains a battery, and battery charging has a certain risk of explosion and spontaneous combustion, the purpose of setting the charging base chambers 121 to be mutually isolated is to prevent the explosion or spontaneous combustion of one or more wireless modules from affecting other chambers and to prevent the failure from further deteriorating.

[0042] Please see Figure 1 The first containment space 11 houses a charging main control module 2 and an interface expansion module 3. Each charging base chamber 121 contains at least one wireless charging module 4.

[0043] In some embodiments, the number of charging socket chambers 121 can be 28.

[0044] Figure 2 This is a circuit structure block diagram of the wireless module charging cabinet for the electronic dosimeter in some embodiments of this utility model. For example... Figure 2 As shown, the interface expansion module 3 is electrically connected to the charging main control module 2, and each wireless charging module 4 is electrically connected to the interface expansion module 3. Specifically, each wireless charging module 4 is used to charge the wireless module. Since there are many wireless charging modules 4, but the number of communication interfaces of the charging main control module 2 is limited, the interface expansion module 3 is electrically connected between the charging main control module 2 and each wireless charging module 4 to expand the communication interfaces, so that each wireless charging module 4 can communicate with the charging main control module 2. The charging main control module 2 is used to control the operation of each charging main control module 2. In some embodiments, the charging main control module 2 can obtain charging status, temperature, humidity and other charging condition data of the wireless module for easy display on the display terminal.

[0045] In some embodiments, such as Figure 1 As shown, each charging base chamber 121 is provided with a sub-partition plate 1211 that divides the charging base chamber 121 into two sub-chambers. Correspondingly, each sub-chamber can be equipped with one wireless charging module 4. That is, when the number of charging base chambers 121 is 28, this utility model can be configured with a maximum of 56 wireless charging modules 4, which significantly increases the number of wireless modules that can be charged. It can be understood that the function of the sub-partition plate 121 is to isolate the two wireless charging modules 4 in the same charging base chamber 121 from each other to prevent the aggravation of fault events caused by a single wireless module.

[0046] In some embodiments, such as Figure 3 As shown, each wireless charging module 4 includes a wireless charging circuit 41 for charging the wireless module, a temperature and humidity sensing circuit 42 for sensing the temperature and humidity inside the corresponding charging chamber 121, a processing circuit 43 electrically connected to the wireless charging circuit 41 and the temperature and humidity sensing circuit 42, and a first communication circuit 44 electrically connected to the processing circuit 43 and the interface expansion module 3.

The node connecting pins 6 and 19 of the wireless charging control chip U2 is connected to the connection node between the fourth capacitor C4 and the CBB capacitor CBB1. Pin 6 of the wireless charging control chip U2 is also grounded through the tenth resistor R10 and the sixth capacitor C6.

[0055] In some embodiments, such as Figure 6 As shown, the processing circuit 43 may include a first processor U6, buttons (not shown), and related peripheral electronic components (not shown).

[0059] In some embodiments, such as Figure 8As shown, the status display circuit 46 may include a first LED D1, a second LED D2, a third LED D3, a fourth LED D4, a fifth LED D5, and a sixth LED D6.
