Adopt above-mentioned technical scheme, through placing the slide glass on the objective table, the identification code that the sign indicating number corresponds is swept to the rethread wide angle camera, give identification code information back to the main control board, the main control board is called out corresponding photo from high in the clouds picture storehouse through the internet, show from the display screen again, can realize the effect that the picture shows, both can satisfy the feeling of operation, can experience microscopical effect, effectual purchase with high costs and experimental sample and the problem of preserving have been solved, rotary encoder just reversing can give the main control board with signal feedback, the main control board carries out the picture amplification when detecting rotary encoder clockwise turning, the picture reduces when the main control board detects rotary encoder anticlockwise turning.

The invention further provides that: the main control board adopts an ARM embedded development board and adopts six-layer PCB process design.

By adopting the above further arrangement, the impedance of the power plane can be effectively reduced, and the magnetic flux offset effect is effective.

The invention further provides that: the display screen, the rotary encoder and the wide-angle camera are respectively arranged on different circuit boards, the circuit boards adopt a PCB double-layer or single-panel process and are connected with the main control board through FPC flexible flat cables of 150mm and 300 mm.

Adopt above-mentioned further setting again, install through the circuit board of difference for can not mutual interference when using, it is more stable when using, it is more convenient when installing, also more convenient when the line.

The invention further comprises the following steps: the rotary encoder comprises a coarse rotary encoder and a fine rotary encoder.

Adopt above-mentioned further setting, can be used for simulating thick accurate focus spiral and simulation thin accurate focus spiral for the operability is stronger when the microscope model uses.
