Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
As shown in figure 1, the microsatellite high-speed serial port power supply integrated tester comprises a PC (personal computer) 1, a USB interface chip 2 capable of being directly identified into a serial port, an FPGA (field programmable gate array) module 3, an optical coupling isolation unit 4 and a serial port module, wherein the USB interface of the PC 1 is connected with the USB interface chip 2, the serial port of the USB interface chip 2 is connected with the FPGA module 3, the FPGA module 3 is connected with the serial port module through the optical coupling isolation unit 4, and the FPGA module 3 adopts a serial port IP (Internet protocol) core design, so that baud rate configuration can be flexibly configured, and a high-speed communication function is realized.
Due to the characteristics of high main frequency and parallel processing of fpga, a design scheme taking fpga as a core is adopted. The method is realized in the FPGA, and the Baud rate configuration can be flexibly configured by the customized serial port IP core design, so that the high-speed communication function is realized. The USB interface chip 2 is directly powered by the USB of the PC 1, so that the power supply problem is avoided. And the USB interface chip 2 can be directly identified as a serial port and is directly observed by a serial port assistant. The normal baud rate equipment adopts an optical coupling isolation DC to ensure the safety of the on-board interface. The high baud rate equipment is not connected with the optical coupler for isolation, and the limitation of the optical coupler for isolation on high baud rate transmission is mainly considered.
A serial port module: two 422 serial controllers 5 and 6 are constructed on software, and two serial controllers are omitted. The serial port module realizes that the 422 data is directly converted into 232 data and directly transmitted to the PC 1.
The model of the USB interface chip 2 is preferably PL2303, which is a USB to 232 module.
In the first implementation example of the invention, an HG4930 three-axis MEMS gyroscope of HONEYWELL is tested.
The performance index of the fiber optic gyroscope of the United states Honeywell company is superior, but through testing, the baud rate of the product is found to be 1Mbit, the transmission data is very large, the general maximum design in China is 115200bit, the serial port communication equipment on the direct purchase market can not accept the data, the invention solves the above problems, and meanwhile, the invention can be set according to different transmission rates, thereby providing powerful support for product type selection.
The invention provides a high-speed serial port power supply integrated tester for a microsatellite, which realizes flexible baud rate configuration and customized serial port IP core design by compiling fpga and realizes a high-speed communication function. USB interface chip to by the direct power supply of PC USB, remove the power problem from.
The invention provides a high-speed serial port power supply integrated tester for a microsatellite, which adopts a test box structure, and a USB port of a test box is connected with a USB port of a computer to be electrified and operated. For devices with different baud rates, different 422 interfaces can be accessed for use. The safety and the convenience are realized; the size of the whole test box is only 170mm x 100mm x 45mm, the USB directly supplies power, and the USB can receive the power by using the universal serial assistant software, so that secondary development is facilitated; the other index requirements of the test box are improved according to the requirements, and a chip with lower cost can be selected; if the data is more convenient to observe, special PC software can be written for realization.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details.
