Embodiment 1

[0043] Such as figure 1 As shown, a program reconfiguration system for on-board solid-state memory includes a management unit, a program loading unit and a program storage unit. Analyze, reassemble and verify the structured data packets; the program loading unit and the management unit are connected through the internal data bus, which is used to transmit the verified data to the program loading unit through the internal data bus; the program storage unit and the program loading unit The connection is used to store the data received by the program loading unit. There are several program loading units and program storage units, and the number of program loading units and program storage units is the same. The verified data is transmitted through the internal communication protocol.

Embodiment 2

[0045] The management unit is an 8086 series processor, the internal data bus is a CAN bus, and the program storage unit is a NOR Flash. All the other contents are the same as in Example 1.

Embodiment 3

[0047] The external control bus is RS422 bus, and the program loading unit implements data loading through ASIC. All the other contents are the same as in Example 1.

Abstract

The invention discloses a program reconstruction method, system and device for a satellite-borne solid-state memory, and belongs to the technical field of electronic information. The management unit interacts with an external upper computer and is used for analyzing, recombining and checking the received reconfiguration program data packet and transmitting the program reconfiguration data to the program loading unit. The program loading unit is used for receiving the program reconstruction data transmitted by the management unit and writing the data into the program storage unit. The program storage unit interacts with the program loading unit to serve as a final storage carrier of the solid-state memory program. The method has great significance in repairing software defects and increasing new functions of software, and the working reliability and flexibility of the satellite-borne solid-state memory can be improved.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to a program reconfiguration method, system and equipment of an on-board solid-state memory. Background technique [0002] The Earth Remote Sensing Satellite (EOS) aims to obtain the ground remote sensing information of the flying area and transmit it to the ground users for utilization. The ground data receiving stations of satellite users in my country are generally located in my country. In order to obtain ground remote sensing information abroad, the ground information obtained when the satellite flies abroad must be temporarily stored in the on-board large-capacity memory, and passed through when the satellite transits the country. The antenna transmits to the ground data receiving station. [0003] The existing domestic on-board solid-state memory usually does not have the function of on-orbit reconstruction of the program, and its program state is fixed, and it d...
