The invention discloses a DC uninterrupted power source based on a cell and and a super capacitor. The DC uninterrupted power source based on the cell and and the super capacitor comprises a rectification circuit, a DC / DC voltage stabilizing unit, a cell charging / discharging circuit, a super capacitor charging / discharging circuit and two voltage stabilizing capacitors. The DC power source employs a method combining the super capacitor and the standby power source, when AC input is normal, the cell and the super capacitor are for charging; when AC input is abnormal, the super capacitor discharges within the cell discharging switching time, so seamless switching of the standby power source is guaranteed, the DC uninterrupted power source is suitable for occasions having strict power source requirements, the DC uninterrupted power source can further adapt to different input voltages, the DC uninterrupted power source further has advantages of relatively small volume, small part quantity and relatively low manufacturing cost, and the DC uninterrupted power source is suitable for popularization and application.

The invention discloses a dual-mode communication system based on a wireless ad hoc network and BeiDou RDSS technology and a communication method. A BeiDou transmitting-receiving link comprises a BeiDou RDSS baseband solution module connected to the control interface and the data interface of a master controller, and an analog-to-digital and digital-to-analog converter and a Beidou RDSS RF transmitting-receiving functional module which are successively connected with the BeiDou RDSS baseband solution module. A wireless ad hoc transmitting-receiving link includes a wireless ad hoc baseband processing module connected to the control interface and the data interface of the master controller, and an analog-to-digital and digital-to-analog converter and a wireless ad hoc RF transmitting-receiving functional module which are successively connected with the wireless ad hoc baseband processing module. The master controller is configured to perform communication channel signal monitoring and communication channel transmitting-receiving monitoring on the BeiDou RDSS baseband solution module and the wireless ad hoc transmitting-receiving link, and to switch the communication modes according to a monitoring situation, wherein the communication modes includes at least one of a fusion mode, a store-and-forward mode, and a BeiDou RDSS short message relay mode.

The invention relates to a service plug-in management method and system. The service plug-in management method comprises the following steps of S1, monitoring update states of a service plug-in configuration file and a service plug-in realization file; S2, when it is discovered that the service plug-in configuration file and / or a service plug-in realization file are / is updated, loading configuration file information and realization file information of a service plug-in needed to be updated to create a new service object instance, and adding the new service object instance to a service object instance pool; S3, updating service plug-in information in a service registry by the newly created service object instance; and S4, deleting an original service object instance from the service object instance pool when the original service object instance of the updated service plug-in in the service object instance pool is idle. According to the service plug-in management method and system, the service plug-in can be automatically and seamlessly updated, and the execution of an existing service is not interrupted.

The invention discloses a random access method, base stations, user equipment and a system. The method comprises the following steps: a target base station receives a switching request message sent by a source base station; the target base station determines the random access component carrier (RCC) of the UE (User Equipment) on the target base station and sends a switching request response message to the source base station, and the switching request response message comprises the RCC information and random access resource information on the RCC; the source base station receives the switching request response message and sends a switching command; and after receiving the switching command, the UE keeps communicating with the source base station and initiates a random access process at the RCC. Through the invention, the seamless switching of the UE from the source base station to the target base station is ensured, and business interruption is reduced.
