The invention discloses a multifunctional intelligent interactive terminal, which comprises a data processing and controlling module, a data storage module, a TCP / IP (transmission control protocol / Internet protocol) encryption module, a wire communication module, a wireless communication module, an uplink communication module and a downlink communication module. A communication method for the terminal comprises the processes of data acquisition, data processing and data transmission and supports wire and wireless communication channels, wherein the wire communication mode is Ethernet communication, and the wireless communication is a 3G mode. The uplink communication mode supports an Ethernet channel and a 3G wireless channel, one of the Ethernet and the 3G is configured as a main channel, the other channel is configured as a standby channel, and the channels are mainly used for remote communication of the equipment; and the downlink communication mode supports the Ethernet channel, and is mainly used for local communication of the equipment to meet the communication of a local area network in industrial application. The terminal has the advantages of convenience for operation, reliable operation, high information transmission quantity and high transmission speed, can provide convenient and efficient power utilization information and power utilization service with strong interactivity for users, and realizes the function of an intelligent power utilization interactive service platform.

The invention discloses a DHBS based on SOA and cloud storage, which is characterized in that the framework of the DHBS is based on an SOA model. The DHBS comprises a console system serving as a cloud service terminal, and at least one substation monitoring system serving as a client, wherein the console system is in data connection with the substation monitoring system; the console system comprises at least one cloud storage service terminal and a data memory; the substation monitoring system comprises a host, a slave and lower intelligent monitoring equipment; the host and the slave are connected with the lower computer monitoring equipment through a bus; each of the host and the slave is provided with a data memory; and the host and the slave are in data connection with the cloud storage service terminal. The DHBS and the method thereof based on SOA and cloud storage avoid the risk problem of single point of failure when using a disk array, overcome the defects of weak real-time data replication and complicated synchronized data recovery between servers in common software hot backup, improve the whole switching time to millisecond level which only spends 50 ms-100 ms.

The present invention provides a conference backup method and device. The method includes: a conference node detects a first module working abnormally in the modules of the conference node, wherein the modules include at least one of the following: a conference service module, a calling service module and a media service module; and the conference node replaces the first module with a second module, so as to support a conference held at the conference node. The second module includes modules at other conference nodes except for the conference node. The present invention resolves the problem of wasting conference resources, implements interacting backup of resources between the conference nodes, and reduces waste of the conference resources.

The invention discloses a distributed data center heat recovery and heating system, which relates to the intersection fields of HVAC and information network. The invention includes: a cabinet, a server and a heat recovery heating module. The server is located inside the cabinet and placed in the user's home to provide data computing and storage capabilities for local and remote users; the heat recovery and heating module recovers the waste heat of the server to provide heat for local users. In the present invention, the servers that were originally placed centrally are distributed in the user's home or local community, and the heat dissipation of the server is used to provide heat to the user's home, so as to improve the utilization rate of waste heat in the data center; when there is no need for heat supply, the excess heat is dissipated into the surrounding environment , the heat dissipation is relatively dispersed, and the efficiency is higher, which effectively weakens the local heat accumulation effect and ensures the stable operation of the server. It not only solves the shortcomings of the centralized data center, such as large footprint, high construction and operation and maintenance costs, and difficult heat dissipation, but also uses the heat dissipation of equipment servers to provide heat for homes.

The invention provides a ground power supply intelligent control system for a satellite electrical test, and the system comprises a solar cell simulation array, a solar cell simulation array controller, a control actuator and a power control box; the solar cell simulation array is respectively connected with the solar cell simulation array controller, the control actuator and the power control box; the control actuator is respectively connected with the solar cell simulation array controller, the power control box and a satellite; the power control box is used for providing power control for the solar cell simulation array and the control actuator; the solar cell simulation array is a power supply unit which simulates the power supply of the satellite solar cell array; the solar cell simulation array controller is used for setting the power output of the solar cell simulation array; and the control actuator supplies power to or cuts off the power of the satellite according to the output of the solar cell simulation array or the solar cell simulation array controller. The ground power supply intelligent control system for the satellite electrical test has a good effect and plays an active promoting role in simplifying the posts of satellites and other spacecrafts, improving the efficiency, implementing automatic electric test, improving the universality of equipment and the like.
