Embodiment Construction
[0014] The infrared analog detector of the present invention is divided into two parts: hardware architecture and software control. In the hardware architecture, the central processing unit is composed of DSP+FPGA chips, the data storage module is composed of SRAM chips, and the program execution module is composed of SDRAM and FLASH chips. The main interface and the A / D chip constitute the external drive signal receiving module, which includes the interface with the drive circuit of the infrared imaging electronic components, the bias voltage overvoltage monitoring module, the power-on sequence detection module, and the analog signal output module It includes a D / A chip that converts the digital signal output from the central processing unit into an analog signal and an amplifier circuit that enhances the signal. The software control part is a software console of the upper computer, and the instructions of the upper computer are directly sent to the central computer through the...
