[0082] In this embodiment, the wiring diagram is a line diagram including the wiring structure between all door indoor units in the building.

[0083] In this embodiment, the Ethernet interface is a communication interface required to realize wired communication between different indoor units and outdoor units using the Ethernet communication protocol. The Ethernet interface types include RJ45 interface, RJ11 interface (telephone line interface), and SC optical fiber interface.

[0084] In this embodiment, the preset Ethernet communication protocol is a preset Ethernet communication protocol used when implementing communication functions between different indoor units and outdoor units.

[0092] During this process, the outdoor station at the starting point can obtain the cycle confirmation status of other outdoor stations and indoor stations in the status cycle confirmation transmission path based on the status confirmation feedback received from other outdoor stations and indoor stations in the status cycle confirmation transmission path and the reception time. At the same time, other outdoor stations and indoor stations in the status cycle confirmation transmission path obtain the cycle confirmation status of the outdoor station at the starting point based on the received status confirmation data packet and the reception time.

[0093] In this embodiment, the status confirmation data packet is a preset data packet (heartbeat packet) used to be continuously transmitted in the status cycle confirmation transmission path to further determine the communication status of all outdoor units and indoor units in the status cycle confirmation transmission path.

[0102] Otherwise, it is determined that the status confirmation data packet received in real time by the corresponding indoor unit or outdoor unit does not meet the corresponding status confirmation reception time:

[0103] Determine whether the starting source object of the status confirmation data packet received in real time by each indoor station and each outdoor station (i.e., the outdoor station at the starting point of the corresponding status cycle confirmation transmission path, because the status confirmation data packet received by the indoor station or outdoor station will contain the information of the transmission source party, so the information of the outdoor station at the starting point of the corresponding status cycle confirmation transmission path can be seen according to the received status confirmation data packet) is the corresponding outdoor station in the status confirmation receiving object, and if so, determine that the status confirmation data packet received in real time by the corresponding indoor station or outdoor station meets the corresponding status confirmation receiving object;

[0117] When only one hypothetical confirmation path starting from the door station and running through all the same path terminals in the corresponding same path terminal set can be determined in some wiring paths, the corresponding hypothetical confirmation path is used as the state period confirmation transmission path;

[0118] Determine, in the partial wiring path, at least one hypothetical confirmed path starting from the door phone and running through all the sibling path terminals in the corresponding sibling path terminal set, and determine a sibling path terminal sequence based on the running order of all the sibling path terminals in the corresponding sibling path terminal set in the hypothetical confirmed path;

[0119] Calculating a hypothetical received data loss rate of each sibling path terminal in a sibling path terminal sequence based on the wiring path information of each sub-wiring path in the sub-wiring path sequence included in the hypothetical confirmed path;

[0120] Based on the assumed received data loss rates of all the same path terminals in the same path terminal sequence, the confirmation accuracy evaluation value of the assumed confirmation path is calculated, and the assumed confirmation path corresponding to the maximum confirmation accuracy evaluation value is used as the state period confirmation transmission path.

[0121] In this embodiment, the original accessible range is the coverage of all the door stations and indoor stations in the multi-terminal topology diagram that have connection lines with the corresponding door stations, and the connection lines can use the same preset Ethernet communication protocol allowed by the corresponding door stations to communicate.

[0122] In this embodiment, the partial wiring path is a partial line included in the multi-terminal topology diagram.

[0123] In this embodiment, the terminal set belonging to the same path is a set of terminals obtained by summarizing all indoor units and outdoor units running through the same part of the wiring path.

[0124] In this embodiment, the same path terminal is a door station or an indoor station in the same path terminal set.

[0125] In this embodiment, it is assumed that the confirmed path is a line starting from the door station and running through all the same path terminals in the corresponding same path terminal set.

[0126] In this embodiment, the traversal order is the order in which all the sibling path terminals in the sibling path terminal set are traversed in the assumed confirmed path.

[0127] In this embodiment, the sibling path terminal sequence is a sequence obtained by sorting all sibling path terminal sets according to the sequence of penetration in the assumed confirmed path.

[0128] In this embodiment, the sub-wiring path sequence is a sequence obtained by sorting the smallest unit partial lines (the smallest unit partial lines are the partial lines in the line that do not pass through any interfaces and relay door units and relay indoor units except the two ends) contained in the assumed confirmed path according to the traversal order in the assumed confirmed path.

[0129] In this embodiment, the sub-wiring path is a partial line in the sub-wiring path sequence.

[0130] In this embodiment, the wiring path information is the relevant information of each sub-wiring path, such as: loss rate per unit length, wiring length, etc.

[0132] The wiring length of each sub-wiring path and the corresponding unit length loss rate are determined from the wiring path information of each sub-wiring path in the sub-wiring path sequence included in the hypothetical confirmation path.

[0133] ρ=1-(1-ρ - )*(1-L*ρ L )

[0134] Where ρ is the assumed received data loss rate of the current calculated sibling path terminal in the sibling path terminal sequence, ρ - is the assumed received data loss rate of the adjacent previous sibling path terminal of the currently calculated sibling path terminal in the sibling path terminal sequence (when the currently calculated sibling path terminal is the second sibling path terminal, ρ - is set to 1), L is the wiring length of the sub-wiring path with the terminal of the currently calculated same-family path as the end point, ρ L The unit length loss rate of the sub-wiring path with the terminal of the same path as the end point currently calculated;

[0135] Based on the above formula, the assumed received data loss rate of each same path terminal in the same path terminal sequence can be accurately calculated;
