In addition, a voice announcer can also be added to remind the user.

[0066] In a possible implementation, a method for collecting radioactive solid waste from a nuclear power plant is provided, the method being applied to a microcomputer, the method comprising:

[0067] Step 100, when a user scans a work badge or identity card to log into the collection system, the microcomputer stores the user's login time;

[0068] Step 101, the user aligns the QR code on the waste bag with the scanner to scan, and puts the waste bag in the measuring slot for weighing and dosage detection, the weighing sensor transmits and records the collected weight data to the microcomputer, and the dosage monitor transmits and records the collected dosage data to the microcomputer;

[0069] Step 102, after the user selects a waste category in the system, the microcomputer opens the electric lock of the cabinet corresponding to the selected waste category and opens the first door; after the user puts the waste into the first collection box behind the first door, the first door is closed and the waste in the first collection box is poured into the space of the second door for accumulation and storage.

[0070] In a possible implementation, the method further includes:

[0071] Step 103, during the use of the waste collection device, the microcomputer classifies the user information of the waste into the specific work items, and simultaneously obtains the total weight of the waste currently collected by each specific work item;

[0072] Step 104, the microcomputer determines the estimated waste production index value of each specific work item within the set time period according to the accumulated waste collection amount corresponding to each specific work item in the set time period in the historical records, and each user can intervene to adjust the estimated waste production index value corresponding to the specific work item of the user;

[0073] Step 105, when the user puts in waste, if the microcomputer determines that the total weight of the waste collected currently exceeds the preset proportion value of the estimated waste production index value, an early warning message is sent to the user. The early warning message is used to remind the waste placing user and the waste management user to control and manage the waste production of the corresponding specific work item.

[0074] For example, first, when in use, the user scans his or her work badge or identity card to log in to the collection system. At this time, the system stores the login time used. The user aligns the QR code on the waste bag with the scanner to scan it, and puts the waste bag in the measuring slot 4 for weighing and dosage detection. The data obtained by the weighing sensor and the dosage monitor are transmitted and recorded in the system. The user selects the waste type in the system, and then the microcomputer opens the electric lock of the corresponding cabinet 5. At this time, the first door 6 is opened, and the user puts the waste into the first collection box 601 behind the first door 6, closes the first door 6, and the waste in the first collection box falls into the space of the second door 7. Subsequently, a dedicated staff member opens the second door 7 to take out the waste accumulated in the cabinet 5;

[0075] Next, after the waste is put into the first door body 6, the servo motor 905 is controlled to start by operating the display 2, driving the bidirectional threaded shaft 906 to rotate. When the bidirectional threaded shaft 906 drives the first internal thread block 907 and the protruding block 910 to move toward the groove block 909, the sliding rope 923 connected to one side of the protruding block 910 is driven at the same time, thereby driving the flap 918 to move downward. During the movement of the flap 918, the slider 917 on one side of the baffle 914 is pushed by the flap 918, thereby driving the baffle 914 to rotate around the hinge point, thereby discarding the compressed waste inside the processing chamber 903 into the inside of the second door body 7; when the protruding block 910 is reset, under the elastic force of the spring 919, the flap 918 is reset at the same time, waiting for the next waste processing;

[0076] Finally, before putting the waste in, the user selects the waste classification in the system, and the microcomputer executes the command to open the first door 6, and the indicator light 8 of the corresponding cabinet 5 lights up, guiding the user to put the waste into the cabinet 5. In addition, a voice announcer can be added to remind the user. In the present disclosure, the edges and corners of the inner wall of the cabinet 5 are rounded to reduce the gaps and dead corners that are easily contaminated, which is convenient for subsequent cleaning and maintenance.

[0077] In addition, the microcomputer in the waste collection device is designed with waste data index management and early warning functions. The microcomputer classifies the user information of the waste and assigns it to the specific work project. When the user puts the waste, the microcomputer distinguishes and counts according to the work project to which the waste category belongs, and counts the cumulative waste weight of each work project. During the use of the waste collection device, the microcomputer can count the waste output of each special work in the set time period, and give the estimated waste output index value of each work project within the set time period through statistical analysis. The waste management user can also intervene to adjust the index value. In this way, in the future set time period, the microcomputer will automatically count the waste weight information put by each special team. In the process of accumulating the actual waste output, a series of preset proportion values ​​of early warning indicators such as 60% and 80% are set. When the accumulated amount of waste is reached, the user is sent an early warning message to remind the waste user and the waste management user to control and manage the waste output of the relevant work project, which is conducive to reducing the output of radioactive waste and meets the requirements of nuclear facility radioactive waste minimization advocated by national laws and regulations.
