after the data packet is transmitted to the transit exchange, the transit exchange can directly transmit the data packet to the backup platform by the above manners (1) - (3) or another existing data packet transmission method, and does not need to transmit the data packet to other exchanges and then transmit the data packet by the server through the transit server of the exchange.
Thus, when the data packet to be transmitted is not in the transmission database at the final place, that is, the backup platform does not establish communication connection with the switch in the current internet, the switch in the current internet does not directly transmit the data packet to the switch for transmission, but transmits the retrieval message to other switches stored in the transmission database to determine whether the backup platform establishes communication connection with other switches, and if the communication connection is established, the data packet is directly transmitted to the backup platform through other switches.
The method for monitoring pathological parameters of a plurality of patients according to the system with application number "201410038077.8", application date "2014.01.26" and patent name "a method and system for monitoring pathological parameters of a plurality of patients" comprises the steps that a receiving device receives a plurality of group transmission signals, and the process of receiving the plurality of group transmission signals is as follows: firstly, receiving a wireless data packet transmitted from a transmitting device and decoding the data packet according to a corresponding decoding mode of a coding mode of the transmitting device; then, the decoded data packet is distinguished and managed according to the control information of the data packet: arranging and storing data packets of different patients, and waiting for a subsequent device to acquire data; meanwhile, the same group management is carried out on the data packet information of the same patient;
however, the data packets of different patients stored by the receiving device singly depend on the receiving device, and the data packets stored by the receiving device when the receiving device is in operation and has faults are often in an unsafe state, and in order to solve the problem, the receiving device also periodically transmits the stored data packets to a backup platform through the internet, wherein the backup platform can be a computer or an internet-based wireless private cloud disk; the number of the receiving devices and the number of the backup platforms are more than one.
The method for the receiving device to transfer the stored data packet to the backup platform through the internet at regular time, the method is operated on a first switch in the internet, and the method comprises the following steps:
(1) receiving a data packet transmitted by a receiving device, wherein the data packet comprises a data frame and an identification code of a backup platform;
the first exchanger in the internet is used for receiving the data packet transmitted by the receiving device and forwarding the data packet to the backup platform;
in (1), a first switch in the internet receives a data packet transmitted by a receiving device, wherein the data packet contains a data frame to be transmitted and an identification code of a backup platform, and the identification code of the backup platform can be a hardware identifier of the backup platform and can also be a unique index set or distributed for the backup platform; the identification code of the receiving device can be a hardware identifier of the receiving device and can also be a unique index set or distributed for the receiving device;
(2) judging whether the identification codes of the backup platforms exist in a database for transmission, wherein the database for transmission comprises the identification codes of all receiving devices establishing communication connection with a first switch in the current Internet and the identification codes of all backup platforms, and the first switch in the current Internet is the first switch in the Internet correspondingly establishing communication connection with the receiving devices;
the method comprises the steps that a transfer database is stored in advance in a first switch in the current Internet, and identification codes of all receiving devices and identification codes of all backup platforms which are in communication connection with the first switch in the current Internet are stored in the transfer database; as in the internet, the exchange in the internet stores a database for transfer in advance, and the database for transfer stores the identification codes of all receiving devices and the identification codes of all backup platforms, which are currently in communication with the exchange in the internet, and the receiving devices can be computers or notebook computers.
When a switch in the current internet receives a data packet transmitted by a receiving device and obtains the identification codes of backup platforms in the data packet, the identification codes of the backup platforms are compared with the identification codes of all receiving devices and the identification codes of all backup platforms in a transmission database stored in advance, and if the identification codes of the backup platforms in the data packet are consistent with one identification code stored in the transmission database, the backup platform transmitted by the data packet can be determined to be positioned in the connection category of the switch I in the current internet;
(3) if the identification code of the backup platform exists in the database for transmission, transmitting the data packet to the backup platform;
when the backup platform to which the data packet is transferred is judged to be located in the connection scope of the first switch in the Internet, the current first switch in the Internet directly transfers the data packet to the backup platform without transferring the data packet to other switches for transferring.
When a data packet to be transmitted is transmitted to a backup platform corresponding to an identification code stored in the transmission database, the receiving device for transmitting the data packet and the backup platform for receiving the data packet are positioned in the same connection category of the switch I, so that the direct transmission method is used, namely, the data packet is directly transmitted to the backup platform through the switch I in the Internet without retransmitting the data packet to other switches in the Internet to perform transmission through the other switches, thereby optimizing the transmission speed of the data packet, and ensuring smooth transmission of the data packet when the transmission data delay or transmission data blockage occurs in the link between the switch I and the other switches in the current Internet; in addition, because the transfer database is stored in the switch in the current internet in advance, when the data packet is transferred, only the identification codes of the backup platform in the data packet need to be compared with the identification codes of all receiving devices and all backup platforms in the transfer database, so that the identification method for judging whether the data packet is directly transferred to the backup platform is not complex and fast, and the transfer speed of the data packet can be ensured.
Before the step (2) is executed, the following method is further included:
(A-A) mass-sending interception messages;
a first switch in the Internet can send an interception message in a group by a method of timing, instruction activation and manual user activation;
(a-B) receiving a first feedback message fed back by all receiving devices and all backup platforms, which establish communication connection with a first switch in the current internet, respectively by means of the received interception message, the first feedback message having an identification code of the receiving device or the backup platform, which correspondingly transmits the feedback message;

in (a-C), if there is no identification code in the database for transfer, directly adding the identification codes of all the receiving devices and the identification codes of all the backup platforms received into the database for transfer; comparing the identification codes of all the receiving devices and the identification codes of all the backup platforms received by each user with the identification codes stored in the database for transferring if the identification codes exist in the database for transferring, and if the received identification codes do not exist in the database for transferring, directly adding the received identification codes into the database for transferring without adding the received identification codes into the database for transferring; in addition, if the receiving device or the backup platform corresponding to the identification code in the database for transmission does not transmit the feedback message, it indicates that the receiving device or the backup platform has cancelled the communication connection to the switch, and the identification code is cleared in the database for transmission.
The identification codes of the receiving devices or the backup platforms which are stored in the database for transmission are identified by the group sending interception message and the receiving feedback message, so that the identification codes of the receiving devices or the backup platforms which are stored in the database for transmission and are in the category of the connection of the switch I can be ensured, and the authenticity of the database for transmission is ensured.

Under the condition that the intercepted message is received by other switches, under the condition, the received intercepted message is not the receiving device or the backup platform but is other switches; after receiving the interception message, other switches also feed back the identification code of the switch to a first switch in the current Internet through a feedback message; when the switch in the current internet receives the feedback message, the identification codes of other switches in the feedback message are added into the database for transmission, and in addition, the switch in the current internet replaces the identification codes of the other switches to add a class identification code for representing that the corresponding part of the identification code is the other switches in the internet instead of the receiving device or the backup platform.
The identification codes of other switches which obtain the intercepted message can be stored in the database for transmission, so that the identification of whether the data packet applies the local transmission method or not can be determined by the stored identification codes of other switches, and the speed of data packet transmission can be improved.
The method for the receiving device to periodically transfer the stored data packets to the backup platform via the internet under the condition that the identification codes of the other switches are added into the transfer database further comprises the following steps:
