Control method for long-term and short-term working module of satellite-borne storage equipment

Technical Field

The invention relates to the field of communication, in particular to a control method of a long-term and short-term working module of a satellite-borne storage device.

Background

The camera load of most satellites in the remote sensing field generally works in a short period, and corresponding storage equipment is also in a complete machine short-period power-on mode; the space station, the palace, the ocean satellite, the telescope and other types of loads generally work for a long time, and the corresponding storage equipment also works by long-time power-up of the whole machine. With the development of technology, the load carried by satellites is more and more, the working modes are different, and short-term working such as optical cameras is performed; some work for a long time, such as laser detection equipment, satellite platform data collection, etc. Aiming at a new application mode, the short-term power-up of a single whole machine cannot meet the use requirement; the long-term power-up of a single whole machine affects the service life of a short-term working module, and increases the power consumption of the whole machine, thereby possibly reducing the reliability index of the whole machine.

The invention provides a control method of a long-term and short-term working module of a satellite-borne storage device, which comprises the following steps:

s1, starting to power up the whole satellite-borne storage equipment, and starting a long-term module to power up by a satellite-borne storage equipment controller;

s2, detecting whether a short-term module of the satellite-borne storage device has an internally proposed short-term module working request of the satellite-borne storage device by the satellite-borne storage device controller, and if so, performing a step S3; if not, repeating the step S2;

s3, detecting whether a short-term module of the satellite-borne storage equipment is in a power-on state or not by the satellite-borne storage equipment controller, and if so, performing a step S4; if not, starting the power-on state and performing step S5;

s4, detecting whether the power-on state of the short-term module of the satellite-borne storage device is in a power-on flow or not by the satellite-borne storage device controller, if so, continuing to finish the power-on flow, and then running the step S5; if not, step S5 is carried out;

s5, starting a short-term module of the satellite-borne storage equipment to work according to a work request;

s6, completing a short-term module work request of the satellite-borne storage equipment, detecting whether other internal requests or external short-term module power-on instructions of the satellite-borne storage equipment exist or not by the satellite-borne storage equipment controller, if so, continuously powering up the short-term module of the satellite-borne storage equipment into a working state, and performing a step S3 according to the new internal requests or the external short-term module power-on instructions of the satellite-borne storage equipment; if not, the short-term module of the satellite-borne storage equipment is powered off.

When the whole machine is powered on, only the long-term module is powered on, and the short-term module is not powered on, so that the power consumption and the heat consumption are reduced. In the process of executing long-term module work, checking whether a first work request of a short-term module is internally provided, wherein the FPGA or the controller of the long-term module can generate the requirement; continuing to execute long-term module work if no requirement exists; the short-term module is ready to be started. Checking whether the current short-term module is already in power-up work, if the short-term module is powered up and is powered up by an external short-term module power-up instruction, the short-term module function required by the first work request can be directly started to be executed. Checking whether the current short-term module is in the power-on process, if the power-on process of the started short-term module is driven by an internal second work request or an external short-term module power-on instruction but is not completed, the power-on process is not repeatedly started, and only checking whether the short-term module is powered on is completed, so that the short-term module function required by the first work request can be directly started to be executed; and waiting if the power-up is not completed. When the corresponding function of the first work request of the short-term module is completed, checking whether there is a new first internal request or a second internal request or a requirement of an external short-term module power-up instruction, if so, maintaining the power-up state and executing the related function, and if not, powering down the short-term module.

The power-on state is a switchable ready state, and when in the power-on state, a work request can be run.
