A control device for an on-board power supply system

Abstract

The invention discloses a control device for an on-board power supply system connected to a 1553B bus, including a CPU, an FPGA, a data buffer chip, and a power supply module; Write the parsed command content into the address corresponding to the FPGA, and the FPGA executes the command content written by the CPU; the CPU also receives the telemetry request sent on the 1553B bus, and controls the FPGA to read the telemetry data of the on-board power supply system in the data cache chip, The telemetry data will be repackaged according to the packet format and the frequency of telemetry data downloading, and sent to the 1553B bus; and, the CPU controls the FPGA to retrieve the telemetry data, and the FPGA stores the retrieved telemetry data into the data cache chip; in addition, the power supply module is CPU, FPGA Provide working power. The control device can realize the data interaction between the ground operation equipment and the on-board power supply system, save the operating time of the CPU, and improve the work efficiency.

Description

technical field [0001] The invention belongs to the design field of aerospace measurement and control power supply control equipment, and in particular relates to a control device for an on-board power supply system. Background technique [0002] In the on-board power supply control electronic products, the research and development of each product is mainly based on model customization, with a single CPU as the control and processing core, and the decoding circuit and gating circuit around the CPU are built by a variety of small and medium-sized integrated circuits. When the ground equipment interacts with the on-board power supply system or manages the storage battery, the CPU needs to complete logical functions such as decoding and gating, and also needs to process the data in real time, and there are various types of interfaces , so that the CPU takes up a large number of operating cycles when processing various logic functions, and the actual data processing capability a...

[0002] In the on-board power supply control electronic products, the research and development of each product is mainly based on model customization, with a single CPU as the control and processing core, and the decoding circuit and gating circuit around the CPU are built by a variety of small and medium-sized integrated circuits. When the ground equipment interacts with the on-board power supply system or manages the storage battery, the CPU not only needs to complete logic functions such as decoding and gating, but also needs to process the data in real time. At the same time, there are various types of interfaces , so that the CPU takes up a large number of operating cycles when processing various logic functions, and the actual data processing capability and resources are greatly limited.

For the increasing number of telemetry and remote control channels in the power system and the complexity of the power control process, the processing resources in single CPU mode can no longer meet the current needs.
