Further, movement core module 42 mainly includes integrated connection as a whole movement core 421, network card adapter board 422, autonomous probe network card 423. Its internal signal is passed to autonomous probe network card 423 by movement core 421 through network card adapter board 422, and is finally connected and transmitted to host computer through the line on socket 32 and interface 33 and image display. Network card adapter board 422 adopts four-layer board type, and signal layer, ground layer, power layer and signal layer are from top to bottom respectively;The positive side of circuit board is placed with the docking interface 50PIN pin of movement core 421, and the back side is placed with the docking interface 100PIN pin of network card, and the two parts are the core connection. The data transmission of network card and movement core is CMOS mode, and the working principle of CMOS image sensor is to convert optical signal into electric signal through the internal structure and assembly of movement core 421, then carry out a series of processing, and finally output digital image signal, so the corresponding pin connection of 50PIN and 100PIN is guaranteed effective communication and CMOS signal transmission. There are 14 main data signal transmission pins in the 50PIN interface provided by movement core 421, from CMOS0 to COMS13;Enable pixel frame effective pin, CMOS_FRAME;Enable pixel bus effective pin, COMS_LINE;Clock pin, COMS_CLK;Data external synchronization pin, EXTERNAL_SYNC;Communication pin, TAU_RX and TAU_TX;The above pins of entire movement core 421 need to be docked.

[0034] And in autonomous probe network card 423, in the 100PIN pin of network card, the pins needed to be used have PB_DATA0-PBDATA13, corresponding to the 14 lines of movement core;Pixel bus pin PB0_LVAL, corresponding to CMOS_LINE;Pixel frame effective pin PB0_FVAL, corresponding to CMOS_FRAME;Clock pin PB0_CLK, corresponding to CMOS_CLK pin;Network card provides two-way serial transmission channel, one is WK_TX, WK_RX, and the serial port is used for communication between network card and movement core;The other is MCU_TX, MCU_RX, and the serial port is a reserved external communication interface, which is not connected in normal use, and needs to be connected when external communication is needed, and does not need to disassemble the equipment;ZL-1, ZL-2 are the focusing interfaces reserved by network card, and two lines output high level or low level, thereby controlling the forward and reverse rotation of motor 411 on connected infrared detector 41.

[0036] Further, for the signal stability processing of the entire probe device, the core module 42 respectively adopts the SN74LVC1G14 chip, which can convert analog signals into digital signals.

This technology can effectively suppress the noise of the input signal and improve the accuracy of signal processing. In addition, the SN74LVC1G14 chip also has good ESD (electrostatic discharge) protection performance. It can withstand electrostatic shocks of up to 2000V human discharge model, 200V machine model and 1000V charging device model. This performance ensures that the chip can still operate stably when facing sudden electrostatic discharge, improving the reliability of the device. At the same time, the SN74LVC1G373 chip is selected, which is a single D-type latch. In digital circuits, buffer registers are used to temporarily store data or signals. Since the SN74LVC1G373 has stable latching function, it can effectively maintain the input data state until there is a clear signal to indicate it to change state. In short, the chip provides a stable data transmission path.

[0037] Further, for the power supply of the network card adapter board 42, a synchronous step-down regulator is selected. The MP2307 chip integrates 100mΩ MOSFETs, which enables it to achieve 3A continuous load current in a wide input voltage range of 4.75V to 23V. Such parameters enable the MP2307 to work stably in different power supply environments and provide uninterrupted stable power output for various electronic devices. In this circuit design, MP2307 is used to reduce the voltage to 5V to power the core 421, so that the core 421 can work stably.

The double-blade switch is in the upward opening mode, which can be used for image signal transmission at this time. The double-blade switch is in the downward debugging mode, which is used for connecting the PC end for serial port debugging. This design avoids the problem of disassembly after the subsequent device assembly is completed, and the debugging function can be completed directly through the side interface 33.

[0039] The core module 42 is composed of the core 421, the network card adapter board 422 and the autonomous probe network card 423, which are three layers of structure, to complete the image signal transmission and finally form an image.
