The invention discloses a data synchronization method during the process of software upgrade, and is mainly applied to the hot-standby systems of a mainframe and a main processor of the mainframe, a standby host and a standby processor of the standby host; the main processor is provided with a main data synchronization management module and a business module of the mainframe; the standby processor is provided with a standby data synchronization management module and a business module of the standby host; the method includes the steps as follows: step 1, description information in the data field of the standby host can be registered and sent to the standby host synchronously by the main data synchronization management module; description information in data field of the mainframe can be registered and sent to the mainframe synchronously by the standby data synchronization management module; step 2, after the business module of the mainframe send the contents of the data field to the standby host synchronously, the standby data synchronization management module carries out the reconstruction processing of the contents in the data field according to the description information in the data fields on the mainframe and the standby host; The invention realizes the seamless software upgrade of the hot-standby system during the process of the version upgrade of the mainframes and standby hosts.

The invention discloses a firmware upgrade method for an embedded system. The firmware upgrade method for the embedded system comprises the steps of initializing an upgrade curing area, starting a watchdog program and timing; judging whether an upgrade instruction is received within preset time or not; if the upgrade instruction is received, executing the upgrade instruction in the upgrade curing area and thus completing the upgrading of an application program. According to the firmware upgrade method for the embedded system, the embedded system can wait for upgrading within relatively long preset time to ensure upgrading of the embedded system.

The invention relates to a software on-line upgrade method and a system, wherein, the method includes: step 1. first equipment sends an upgrade request to an upgrade control module; step 2. the upgrade control module determines whether an upgrade data storage module needs to provide an upgrade data packet, if yes, the step 3 is implemented; otherwise, the step 5 is implemented; step 3. the upgrade control module sends the notice information of downloading of the upgrade data packet from the upgrade data storage module to the first equipment, the step 4 is implemented; step 4. the first equipment downloads the upgrade data packet from the upgrade data storage module; step 5. the upgrade control module sends the notice information of downloading of the upgrade data packet from a second equipment to the first equipment, the step 6 is implemented; step 6. the first equipment downloads the upgrade data packet from the second equipment. The software on-line upgrade method and system which is provided by the invention can reduce the number of the upgrade servers, improve the using efficiency of the upgrade servers and ensure the completion of upgrade of a large number of equipments in a short time.

The invention relates to a multi-connected air conditioning unit and a remote upgrading method thereof. The multi-connected air conditioning unit remote upgrading method comprises the steps that eachmulti-connected air conditioning unit is remotely upgraded through a GPRS module, the GPRS module adopts an election mechanism in a network, and when the GPRS module is elected, a selected zone bit and upgrading packet data are sent to a bus; and when the GPRS module is not elected, whether a selected zone bit or upgrade package data exists on the bus is judged, if so, the election is not participated in, and if not, the election is participated in. When the GPRS module is used for upgrading the air conditioning unit, the elected GPRS module sends a large amount of upgrade package data to thebus; even if the non-elected GPRS module cannot receive the selected flag bit sent by the bus within the preset time, the selected flag bit cannot be received by the unelected GPRS module; when the GPRS modules are not elected, the GPRS modules receive the upgrading package data sent by the bus, once the GPRS modules which are not elected receive the upgrading package data, it is indicated that one GPRS module is elected under the same project, the GPRS modules do not participate in election, and therefore normal upgrading of the air conditioning unit is guaranteed.

The present invention provides a non-invasive method for implementing security audit of a business system. The non-invasive method for implementing a security audit of a business system is based on a sidecar model that combines the security audit module with a business application system in a non-invasive manner. The audit module and the business application system are deployed in a node at the same time, and the security audit module has the same life cycle as the application service of the amateur application system, so that the corresponding client can perform security audit operations. This method can integrate the business application The control function of the system is effectively separated from the logical function of the security audit module, so as to ensure the normal operation, maintenance and upgrade of the business application system and the security audit module.

The invention relates to a method for enhancing Quality of Service (QoS) of uplink business in a hybrid passive optical network, which comprises the following steps: a. when generating a new uplink data stream, an optical network unit (ONU) of a hybrid passive optical network (HPON) firstly reports the characteristic of the data stream to an optical link terminal (OLT) through control information; b. the OLT judges the newcoming data stream according to a preset admission control algorithm, wherein if the remaining uplink bandwidth of the system is sufficient, the data stream is admitted, and else, the data stream is refused; c. the OLT calculates the transmission time allocated to each ONU according to the admitted data stream parameters in each period, which means that the ONU can continuously transmit the data time to the OLT and inform the corresponding ONU through the control information; and d. after acquiring the right of control, the ONU transmits the uplink data according to the time allocated by the OLT. The method can be used for acquiring determined QoS in an HPON system capable of sharing uplink wavelength, so that the HPON system can better support real-time services.

The invention discloses a version upgrading method and a version upgrading device. The version upgrading method comprises the following steps of transmitting a first version information detection instruction which is used for indicating a server to detect stored version information at preset time intervals by using a smart television; receiving a first version information message which is transmitted by the server and at least comprises the version information stored by the server; judging whether the version information stored by the server is the same with the current version information of the smart television or not; and transmitting an upgrading instruction to the server if the version information stored by the server is different from the current version information of the smart television, and receiving version data to upgrading version. The smart television automatically transmits the first version information detecting instruction to the server at preset time intervals so as to detect whether self version information is the information of the newest system version; when the information of the current smart television is not the information of the newest version, the upgrading instruction is transmitted to acquire the information of the newest system version, then the information of the newest system version is loaded, and the information of the current smart television is upgraded; a user can upgrade electronic equipment for the first time; and the version upgrading efficiency is high.
