Message processing method and equipment

The invention relates to the field of communication, and particularly relates to a message processing method and related equipment. The method comprises the following steps: terminal equipment sends a request message to a server before sending a service message, wherein the request message is used for requesting to allocate identifiers of network slices; the server allocates the identifiers of the network slices to the terminal equipment according to the service type of the terminal equipment, and sends the identifiers of the network slices to control equipment; the control equipment determines parameter information of the network slices according to the identifiers of the network slices and determines a forwarding path according to the parameter information; and then the control equipment adds forwarding resources included in the forwarding path to the forwarding resources of the network slices; and when the terminal equipment sends the service message, the service message is forwarded through the forwarding resources of the network slices. Through the above scheme, the control equipment can dynamically determine the forwarding resources for the network slices according to service requirements, and thus the forwarding resources in networks can be fully used, the forwarding resources can be saved, and the flexibility of the networks can be improved.

On-line monitoring system and monitoring method for distributed cable terminals

The invention relates to an on-line monitoring system and a monitoring method for distributed cable terminals, and belongs to the measurement field. The whole system is divided into three layers from top to bottom. The bottom layer is a target layer comprising wireless temperature sensors mounted on temperature measuring points, each sensor monitors the temperature of one monitored target and transmits data to the outside through wireless methods; the middle layer is a partition layer comprising a wireless communication gateway, switch cabinet or voltage intervals can be taken as targets by the wireless communication gateway to perform configuration as required on site; the collected measuring results can be transmitted by the wireless communication gateway through various channel methods ready on site; the top layer is a station layer comprising a central server for gathering monitoring centers; and data transmitted by the wireless communication gateways can be received by the central server through various channel methods ready on site, and are displayed, stored and analyzed by the central server, so that out-of-limit warning or accident pre-warning functions can be realized. The on-line monitoring system and the monitoring method for the distributed cable terminals can be widely applied to the equipment condition monitoring field of power systems.

Ultra-wideband indoor positioning method

ActiveCN106793060AFlexible configurationImprove Clock Synchronization AccuracySynchronisation arrangementNavigational calculation instrumentsBroadbandIndoor positioning system
The invention provides an ultra-wideband indoor positioning method, which mainly solves the problems of low precision, limited user quantity, great time synchronous errors and the like of the existing ultra-wideband indoor positioning system. The method comprises the steps of firstly, building an indoor navigation coordinate system, and arranging a base station; secondly, sending a positioning signal by the base station according to a system signal communication mechanism, so that positioning equipment held by a user only passively receives a distance measuring signal from the base station; then, realizing clock synchronization on an algorithm by using a clock deviation compensation algorithm of a Kalman filtering algorithm; finally, solving the user coordinate by a Taylor iterative algorithm. The ultra-wideband indoor positioning method has the advantages that the goal of simultaneously realizing indoor three-dimensional accurate positioning of infinite positioning equipment can be achieved; an additional hardware network is not needed for realizing clock synchronization; the positioning equipment only receives a positioning signal but does not send the signal; the stable swinging can be realized between a sight distance scene and a non-sight distance scene.

Main-standby virtual gateway system and method based on SDN

The invention discloses a main-standby virtual gateway system and method based on the SDN. The system comprises outer net equipment and a main-standby virtual gateway connected with the outer net equipment, the main-standby virtual gateway comprises a main interchanger and multiple standby interchangers, the main interchanger and the multiple standby interchangers are all connected with an SDN controller, and the main interchanger is connected with multiple hosts. The method comprises the steps that the SDN controller starts the virtual main-standby gateway function; the SDN controller involves the interchanges into the virtual gateway and sets the priorities of the interchanges in the virtual gateway; the main interchanger is selected to be used; the main interchanger forwards a message; whether the main interchanger works normally or not is judged, if yes, message forwarding is continued, and if not, the main interchanger is reselected. By means of the main-standby virtual gateway system and method, reliability is improved, and meanwhile host configuration is simplified. With the help of the virtual gateway, a high-reliability default link can be still provided in case a certain interchanger breaks down, and the problem of network interruption occurring after a single link breaks down is effectively avoided.

Solar power supply system with a plurality of battery packs

Provided is a solar power supply system with a plurality of battery packs. The solar power supply system with the battery packs comprises main-and-auxiliary double solar cell panels, a plurality of lithium battery pack energy storage elements, a front end DC/DC voltage change circuit, charging and power supply management circuits, a rear end DC/DC voltage change circuit, an electric quantity detection circuit, corresponding battery protection circuits and a central processing unit CPU. The lithium battery packs are adopted and serve as the energy storage elements, the CPU is used for carrying out energy management on each lithium battery pack, and even when one lithium battery is abnormal, normal operation of the solar power supply system cannot be influenced. Meanwhile, due to the fact that the working mode of the main-and-auxiliary double solar cell panels is adopted, when the main-and-auxiliary double solar cell panels are applied on site, the auxiliary solar cell panel is configured as needed, and flexible configuration of model selection of the solar cell panels can be accomplished. When the solar power supply system with battery packs is used for carrying out charging, efficient charging is carried out on the lithium battery packs according to an MPPT control method, according to the result after the solar power supply system with battery packs is tried out, a power system is good in operation, and the strong guarantee is provided for dynamic improvement of the capacity of power transmission lines, and the stability and the reliability of the solar power supply system.
