Background
The optical signal transmission means that an optical signal emitted by a laser is conducted to an optical fiber through an optical device and transmitted to a receiving end through the optical fiber, so that the signal is transmitted in the optical fiber, and the purposes of improving the transmission rate, capacity and transmission distance are achieved.

In the hard mirror system design of gastroscopes, it has been the conventional practice to use copper wires to transmit high speed video signals (video signals collected from a front-end camera), low speed control signals, and power signals. In the past, the design of the copper wire gastroscope system has two defects, firstly, a copper wire signal is on a hard mirror device held by a doctor, and a signal processing chip (CDR or EQ chip) is added due to the loss of the copper wire, so that the power consumption is large and heat is generated, the temperature of the handheld electronic device is higher than that of the common electronic device when the doctor holds the handheld electronic device (generally, 30 degrees or 40 degrees is possible), and the doctor feels uncomfortable and inconvenient for the handheld electronic device with the higher temperature in the operation process. Secondly, the copper wire signal is too thick, which is not easy for the doctor to hand the device to move conveniently.

Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
Example 1
Referring to fig. 1 and 2, the present invention provides a photoelectric transmission system for a gastroscope system, which includes a transmitting module 1, a photoelectric hybrid cable 2 and a receiving module 3, wherein the transmitting module 1 is connected to one end of the photoelectric hybrid cable 2, and the receiving module 3 is connected to the other end of the photoelectric hybrid cable 2. The transmitting module 1 comprises a transmitting end connector 11, a transmitting end shell 12 and a photoelectric conversion transmitting end circuit board, wherein the transmitting end connector 11 is arranged on one side far away from the photoelectric mixed cable 2. Receive module assembly 3 with the transmission module assembly 1 sets up for the symmetry, receive module assembly 3 includes receiving end connector 31, receiving end shell 32 and photoelectric conversion's receiving end circuit board, the receiving end circuit board with receiving end connector 31 circuit connection, receiving end shell 32 cover is located receiving end connector 31 with the receiving end circuit board is outside.
In this embodiment, the photoelectric conversion circuit at the transmitting end converts the high-speed video electrical signal and the low-speed control electrical signal (such as I2C, serial or USB signals) transmitted from the connector portion 11 into optical signals (note that the low-speed control electrical signal may not be converted into optical signals as the case may be), and the photoelectric conversion circuit at the receiving end converts the received optical signals transmitted from the optical-electrical hybrid cable 2 into the high-speed video electrical signal and the low-speed control electrical signal transmitted from the connector portion 31.
Example 2
The shell is provided with a sealing mechanism, and if sealing rings are arranged on the periphery of the shell, the temperature which can be borne by the whole system is more than 150 ℃. Because the gastroscope delivery system of the present invention is not a disposable product, it needs to be sterilized by heat after each use.
Example 3
The photoelectric conversion circuit board comprises a photoelectric chip. Because the power consumption required by photoelectric conversion is less than that of the signal processing chip of the previous copper signal, the optical signal can have the advantages of higher transmission rate and longer transmission distance than the electrical signal.
Example 4
The photoelectric hybrid cable 2 comprises an optical fiber, a power copper wire and a low-speed control signal copper wire. The number of the optical fibers in the photoelectric hybrid cable is 4 or 6. Because the optical fiber is far thinner than the copper wire, the total OD diameter is smaller than the original copper wire, thereby achieving the effect of convenient use and dragging.
