Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 2 As shown, the data cache module includes an input FIFO module, a DDR controller, an image parameter calculation module, a DDR2 SDRAM and an output FIFO module. The output end of the CMOS image sensor is connected to the input end of the input FIFO module, the output end of the input FIFO module is connected to the input end of the DDR2 SDRAM, the output end of the DDR2 SDRAM is connected to the input end of the output FIFO module, the output end of the image parameter calculation module is also connected to the input end of the DDR2 SDRAM through the DDR controller, and the output end of the output FIFO module is connected to the input end of the main control module.

[0030] Among them, the FIFO module is mainly used to solve the problems of inconsistent data bit width and mismatched data transmission speed between modules. DDR2 is mainly used to meet the requirements of high-speed and large-capacity data cache. The data transmission module uses Gigabit Ethernet to send image data in jumbo frame format to the host computer software for real-time display.

[0031] The DDR2 storage capacity selected by the utility model is 2Gbit, with 8 Bank storage blocks. Since the DDR2 read and write operations cannot be performed simultaneously, it is necessary to time-share multiplex the DDR2 address bus to improve its data bandwidth utilization. In order to adapt to image data with different resolutions, an image parameter calculation module is designed to obtain the image data volume and various parameters at different resolutions, thereby providing a theoretical basis for the redistribution of the DDR2 storage space. At the same time, redistributing the DDR2 storage space can realize convenient management and control of image data.

[0032] The data cache module of the utility model adopts a three-level data cache mechanism, utilizing the efficient read and write performance of the internal FIFO and the large-capacity storage of the off-chip DDR2 to form complementary advantages of rate and capacity (time and space), and well meets the performance requirements of the high-speed image data transmission system for image data transmission.

[0033] like Figure 3As shown, the data preprocessing module includes an amplifier circuit and a dual operational amplifier bandpass filter, the amplifier circuit is composed of an OPA277 operational amplifier and a resistor and capacitor, and the dual operational amplifier bandpass filter is composed of two OPA277 operational amplifiers; specifically includes a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, an eighth resistor, a ninth resistor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a first operational amplifier, a second operational amplifier, and a third operational amplifier, wherein the signal input -IN terminal is connected to one end of the first resistor, the other end of the first resistor is respectively connected to one end of the first capacitor, one end of the third resistor and the negative power supply pin of the first operational amplifier, the other end of the first capacitor is respectively connected to the other end of the third resistor and the output pin of the first operational amplifier, and the signal input +IN terminal is connected to the second capacitor The first operational amplifier output pin is connected to one end of the fifth resistor, the other end of the fifth resistor is connected to the positive power pin of the second operational amplifier, the negative power pin of the second operational amplifier is connected to the negative power pin of the third operational amplifier, the positive power pin of the third operational amplifier is connected to one end of the eighth resistor and one end of the ninth resistor, the other end of the ninth resistor is connected to the ground, the other end of the eighth resistor is connected to one end of the seventh resistor and the output pin of the second operational amplifier, the other end of the seventh resistor is connected to one end of the fourth capacitor, the other end of the fourth capacitor is connected to one end of the ninth resistor, the other end of the ninth resistor is connected to one end of the third capacitor, and the other end of the third capacitor is grounded.

At the same time, C3 and R6, C4 and R7 form a low-pass filter. The dual op amp bandpass filter is composed of two OPA277 operational amplifiers. The Q value and center frequency of the bandpass filter designed in this design are adjustable. The resonant frequency of the circuit can be adjusted by adjusting R9, and the Q value of the circuit can be adjusted by adjusting R8. It is worth noting that the array condensation sensor collects the condensation signals at each point, and then selects the multiplexed analog switch to output to the signal processing circuit, and then inputs it to the AD7794 for digital-to-analog conversion, converting the analog signal into a digital signal, which is conducive to long-distance wireless transmission of the signal. It is worth noting that the noise of the 24-bit Σ-Δ analog-to-digital converter AD7794 is only 40nV, and the power consumption current is only 400μA, which is particularly suitable for applications requiring low power consumption and high-precision measurement.

[0034] like Figure 4As shown, the infrared sensor module includes a resistor R5, a resistor R6, a sliding rheostat RV1, a voltage comparator Q1, and an infrared photoelectric module U3; wherein, one end of the resistor R5 is connected to pin 1 of the infrared photoelectric module U3, the other end of the resistor R5 is respectively connected to one end of the resistor R6 and the positive power supply end of the voltage comparator Q1, the pin 2 of the infrared photoelectric module U3 is grounded, the pin 4 of the infrared photoelectric module U3 is grounded, the pin 5 of the infrared photoelectric module U3 is respectively connected to the other end of the resistor R6 and the non-inverting input end of the voltage comparator Q1, the inverting input end of the voltage comparator Q1 is connected to pin 1 of the sliding rheostat RV1, the pin 2 of the sliding rheostat RV1 is connected to the VCC end, the pin 3 of the sliding rheostat RV1 is connected to the negative power supply end of the voltage comparator Q1, and the output end of the voltage comparator Q1 is connected to GD.

DE is the data valid signal, and the high level is valid; HS and VS are the line synchronization signal and the field synchronization signal respectively; D[23:0] is the RGB24 data input bus, which is the R, G, and B component data bus from top to bottom. In order to support other video data formats, the bus width of SiI9134 is 36bit, and only 24bit is used in this system, and the remaining data bus pins are grounded; SiI9134 supports a variety of digital audio signal input interfaces, including S / PDIF, I2S, etc., and the audio interface is not used in this system. The RGB24 format video data is encoded by SiI9134, converted into serial data and sent to the display through the connector and transmission line, ultimately displaying full HD video.
