The invention relates to a fabricated aerobic composting device. The device comprises five parts including a bin body, a fermentation center, aeration tiles, a functional film and a data acquisition and transmission system. According to composting requirements in different positions and at different time, the following working steps are required to be performed: constructing three surfaces of thebin body, reserving one surface as a material inlet, laying the aeration tiles and connecting the aeration tiles with the fermentation center; accomplishing a baffle of the reserved material inlet after material distribution, covering materials with the functional film, and fastening the periphery through wires and baffles; supplying gas to the materials through the fermentation center at the beginning of composting, and transmitting, recording and analyzing data by the data acquisition and transmission system, so as to control the composting speed; opening the film and then opening the baffleat the material inlet after composting is over, shoveling out all of the materials and the aeration tiles, sieving, separating the materials from the aeration tiles, finally dismounting the fermentation center and the bin body respectively and performing separate collection. The aerobic composting device is flexible, reliable, efficient, intelligent and economical.

The invention discloses an identity authentication method and apparatus. The method includes that in response to the authentication of the identity of a second end, a first end randomly selects physical information verification or historical recording verification as a verification mode; based on the selected verification mode, the first end randomly selects one or more from the physical information or historical record corresponding to the selected verification mode as the question correct answer; a question is formed based on the correct answer, and a corresponding question request is issued to the second end; the feedback answer of the question returned by the second end is received; the feedback answer and the correction answer are compared; and in response to the feedback answer being consistent with the correct answer, the identity authentication is passed. The method and device occupy a small amount of data, have high authentication speed and high security, and are particularly suitable for an Internet of things system with a large terminal number and a narrow transmission bandwidth.

The invention discloses a real-time alarm statistical method, which comprises the following steps of: step 1, after receiving an alarm, firstly retrieving in a real-time library, retrieving whether analarm record meeting a statistical rule exists or not, if so, recording statistical times and deleting the alarm record, then inserting a latest alarm and adding 1 to the statistical times, and otherwise, turning to the step 2; and step 2, retrieving in a historical library, respectively retrieving the occurrence times of alarms meeting statistical rules in three time periods of day, week and month, then inserting the latest alarm into a real-time library, and respectively adding 1 to the retrieved times. The frequency of occurrence of alarms meeting statistical rules in three time periods ofday, week and month can be counted in real time, and monitoring personnel can visually see the severity and distribution range of the alarms according to the condition of the frequency of occurrenceof the alarms and master the overall state of the system. The invention also discloses a real-time alarm statistics system.

The invention discloses an evaluation method for wear rate of a reactor core finger sleeve. The method comprises the following steps: acquiring wear defect depth data of the finger sleeve through eddy current detection; calculating wear rate data according to the wear defect depth data; according to the wear rate data, obtaining an empirical distribution function of the eddy current detection wear rate and distribution of the actual wear rate; obtaining distribution of the eddy current detection errors according to the eddy current detection errors; calculating according to the distribution of the actual wear rate and the distribution of the eddy current detection error to obtain an empirical distribution function of an eddy current detection wear rate simulation value; and comparing the two empirical distribution functions, and carrying out iterative calculation until the two empirical distribution functions are matched to obtain the distribution of the corrected actual wear rate. The wear rate of the finger sleeve is evaluated according to the evaluation method, the abrasion trend and the service state of the finger sleeve can be mastered more accurately, and safe and reliable operation of a nuclear power station is facilitated.
