The present invention provides a flat-plate SAR satellite with a standardized satellite platform, including a satellite platform, a solar array and a phased array antenna. In the launch state, the solar array and the phased array antenna are folded into a structure with the same size as the satellite platform. In the on-orbit state, the phased array antenna is unfolded and parallel to the unfolded solar array. The present invention adopts a flat-plate configuration, the internal space of the platform is compact, the outer envelope shape of the whole satellite is regular, and the size distribution of each dimension is reasonable, which is convenient for one-shot multi-satellite layout, and can adapt to the internal space of most carrier fairings on the market to achieve rapid constellation networking; in the later stage, the satellite platform does not need to be replaced for SAR payloads of different sizes, thereby shortening the development cycle and reducing the development cost; the mechanical interface of the present invention is simple, the size of the satellite platform is minimized to be affected by the load change, and the AIT cycle of the whole satellite is effectively shortened; the thruster of the present invention is installed on the satellite platform through an adjustable bracket, and it is convenient to meet the thruster installation requirements through rough and fine position adjustment in the later stage.

The invention provides an SAR satellite structure suitable for multi-satellite launching and a design method, and relates to the technical field of spacecraft design, the SAR satellite structure comprises a satellite main body, a solar wing, a radiation unit, an antenna substrate, a plate penetrating connector, a TR assembly and a semi-rigid connection assembly, the SAR satellite structure adopts a trapezoidal cross section configuration, the internal space of a rocket fairing is fully utilized, and the space of the rocket fairing is fully utilized; a heat conduction unit and a heating unit are arranged between the radiation unit and the antenna substrate and between the antenna substrate and the TR assembly, so that the radiation array plane flatness of the radiation unit and the installation flatness of the TR assembly are ensured, heat conduction between single machines is increased, and the temperature consistency of the antenna is improved; the semi-rigid connection assembly can reduce the response of the active section antenna, release the thermal deformation of the antenna, reduce the flatness change, improve the precision of a radiation array plane, and solve the problems that the space utilization rate of an existing SAR satellite is low, the flatness of the antenna is easily affected by thermal deformation, and the temperature of the antenna is difficult to control.

The invention relates to the technical field of ammeter data acquisition, in particular to an ammeter acquisition method and system based on a Lora radio frequency ad hoc network. The acquisition method comprises the following steps: a node acquires first ammeter data of local ammeter equipment according to an acquisition strategy; the node sends total electricity meter data including the first electricity meter data to a forwarding node or a main router; when the data transmission fails, the node stores the total ammeter data to a local memory; and after the communication is reconstructed, the node calls the total ammeter data which are not successfully sent in the local memory and resends the total ammeter data. The acquisition system and method provided by the invention have the advantages of fast networking and fast deployment. And the problems of complex communication and difficult wiring between devices are greatly solved. For a large amount of dense electric meter equipment, such as a high-voltage power distribution room scene, rapid and comprehensive acquisition can be performed, and the installation position can be rapidly positioned.

The application relates to the technical field of battery management, in particular to an address automatic allocation method, an energy storage system, an energy storage unit and a storage medium. The method is applied to a battery cell unit, at least one battery cell unit is sequentially arranged along a one-dimensional direction, each battery cell unit is provided with an input interface and an output interface, the input interface of each battery cell unit is connected with the output interface of the previous battery cell unit, and the output interface of each battery cell unit is connected with the input interface of the next battery cell unit; the method comprises the following steps: a communication link is established with adjacent battery cell units; an addressing rule is configured, and an addressing task mechanism is started to enable the battery cell units to successfully analyze addresses; whether any data is received by the input interface of the battery cell unit is detected according to a preset first period, if yes, the battery cell unit is determined as a slave; last address information sent by the previous battery cell unit is received, a current address of the battery cell unit is generated according to a preset address generation rule, current address information is generated according to the current address, and the current address information is sent to the next battery cell unit.

The present disclosure discloses an electric-quantity-based path planning method for an electric vehicle compatible with an energy storage charging pile. The method includes the following steps: 1) charging piles in a whole network submitting state information of the piles to a dispatching system platform, and before departure, an electric vehicle applying for a reservation from the dispatching system platform; 2) finding a shortest path from a departure place to a destination; 3) the dispatching system platform judging whether the reserved allocated electric quantity of the electric vehicle at one or more charging piles along the path meets an endurance requirement for driving to the destination; 4) if so, generating a whole-journey reservation scheme; and 5) if not, excluding the shortest path, and finding the shortest path from the remaining paths, and performing cyclic execution from Step 3) until all paths are traversed. By means of the method of the present disclosure, whole-journey electric-quantity-based path planning for an electric vehicle can be realized, the fused use of an energy storage charging pile and a power-grid direct-supply charging pile is realized using arrival time matching, and charging scheduling is also performed on the vehicle through the dispatching system platform, such that the electric quantity of the charging pile resources, especially an energy storage pile, in a whole network is fully utilized.
