The present application relates to a kind of distribution management method, device, storage medium and electronic equipment, it is related to distribution management technical field, the present application constructs user receiving probability distribution model using deep learning, and correction is carried out in combination with real-time telephone communication result, effectively solve the problem of too early or no one to receive mail caused by recipient not at home, greatly reduce the secondary delivery rate and loss risk of fresh products, by injecting the scoring system with fresh type and its preservation threshold as core constraint variable, ensure that the order of high time requirement can obtain higher distribution priority, complete delivery before product quality deterioration, improve user experience, while realizing the balanced scheduling of regional transport capacity through dynamic scoring mechanism, effectively alleviate the technical pain points of uneven resource allocation in peak period, avoid the phenomenon that part of terminal is overloaded while another part is idle, based on real-time scoring dynamically generates path, can flexibly respond to road condition anomaly, user temporary change of mind and other emergent conditions.

The utility model discloses a telephone line special common mode rejection circuit relates to communication anti -interference technical field, and this circuit passes through the synergic design of triode bias circuit, common mode inductance and direct -current capacitor, realizes three major functions: one is high -efficient suppression high -frequency common mode interference signal (the path of conversion into differential mode interference is blocked) ;Two is to provide direct current passage for telephone line to transmit feed current, three is to provide alternating current passage for low -frequency ringing signal. Meanwhile, the circuit has very small transmission influence to differential mode audio signal, can be directly connected in series in ordinary telephone communication equipment, makes it adapt strong interference scene (such as mechanical and electrical equipment, broadcast transmitting station nearby), and the call quality stability is obviously promoted.

The application discloses a telephone line switching device and method, and relates to the technical field of telephone communication, and comprises the following steps: collecting the nominal maximum bandwidth and the actual used bandwidth of each line, obtaining line reference load data based on the nominal maximum bandwidth and the actual used bandwidth; obtaining the actual available bandwidth of the line, adjusting the line reference load data based on the actual available bandwidth, and obtaining line capacity data; obtaining individual sudden drop threshold values through a dynamic adaptive threshold model based on the line capacity data, and judging whether a multi-line synchronous bandwidth sudden drop event occurs based on the individual sudden drop threshold values; the application aims at the problem of bandwidth instantaneous sudden drop caused by the synchronous triggering of the heat protection mechanism of multiple lines in extreme environments such as high temperature, sets individual sudden drop threshold values, screens a bandwidth sudden drop line list, and quickly matches standby switching lines, so that fast response and switching in the multi-line synchronous sudden drop scene are realized, large-scale business interruption is avoided, and communication continuity is ensured.
