Embodiment Construction

[0034] The invention provides an ARM-based on-board energy control system, such as figure 1 Shown, including: ARM chip, analog switch, temperature measurement module, CAN bus interface module, power supply module, watchdog, data storage module and data latch module;

[0035] The power module supplies power to the on-board energy control system. The external analog input signal is input to the ARM chip after the on-off selection by the analog switch. The temperature measurement module used to measure temperature transmits the temperature signals of various parts of the on-board energy to the ARM. Chip, ARM chip communicates with other parts of the satellite through CAN bus interface module, watchdog provides active reset signal for ARM chip, data storage module is used to store temporary data, which is supplied to ARM chip for processing, and ARM chip passes the processed signal through data The latch module outputs data after latching; the temperature measurement module passes I 2...

Abstract

The invention provides an on-satellite energy control system based on an ARM (Advanced RISC Machine). The system utilizes an ARM microcontroller which is high in on-chip resource integration level, small in size and low in power consumption to form an intelligent component used as a core processing module for energy management; multiple on-chip resources such as an analog / digital converter and a CAN (Controller Area Network) which are integrated on an ARM processor are utilized, so that corresponding peripheral circuits are not required to be additionally established so as to realize the control function in a minisatellite energy management process. Therefore, the complexity of a minisatellite energy management system is simplified, the cost of the minisatellite energy management system is lowered, the real-time performance and the integrated level of energy management are improved; and in addition, dynamic management is carried out on loads, during an ontrack running period of a minisatellite, telemetry parameters such as the voltage of a storage battery, the current of a matrix and the load current are periodically monitored, slicing management is carried out on an energy space, and then the divided energy spaces are used by different loads, so as to guarantee the reasonable, safe and effective use of satellite energy and further improve the energy utilization.

Description

Technical field [0001] The invention relates to an ARM-based on-board energy control system, which is suitable for on-board energy control of small satellites. Background technique [0002] At present, the energy control mode of small satellites mostly adopts the MCS-51 as the core microprocessor system and peripheral circuits, and cooperates with the software to form the main body of the intelligent control unit to complete the monitoring and control of the working status of the power system, and the charge and discharge control of the battery pack. And charging current limit control, battery temperature control, engineering parameter collection, remote control command reception and execution, and communication with the satellite service center computer. Modular design is usually carried out on the hardware, but each specific module needs a set of corresponding interface circuits to complete. Take the CPU module as an example. The module includes a controller, program memory, d...
