[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Refer toFigures 1 - 9 , a signal transmission structure of a shared battery swapping communication device, comprising:

[0027] A main transmitting module, a main receiving module and a host. The main transmitting module and the main receiving module are used for transmitting and receiving light waves;

[0028] The main transmitting module includes a photosensitive diode A, an amplifier circuit A, a single-chip microcomputer A and a light-emitting diode A;

[0029] The main receiving module includes a photosensitive diode B, an amplifier circuit B, a single-chip microcomputer B and a light-emitting diode B.

[0030] In this embodiment, both the main transmitting module and the main receiving module are connected to an external power supply.

[0031] In this embodiment, the photosensitive diode A is used to receive a light wave signal.

[0032] In this embodiment, the amplifier circuit A is used to amplify the signal.

[0033] In this embodiment, the single-chip microcomputer B is used to calculate the received light wave, convert it into a binary digital signal, and give it to the host.

[0034] In this embodiment, the light-emitting diode A is used to emit light waves.

[0035] In the present utility model, by transmitting digital signals in the form of light wave signal conduction, problems such as metal fatigue breakage and corrosion of communication wires and plug connectors between devices can be solved, resulting in communication failures.

[0036] The main transmission module of the present invention is the main board, which is connected to the optical wave transceiver circuit board and installed inside the battery. The main receiving module is the receiving optical wave circuit board connected to the host. When the main receiving module sends out a wake-up instruction, the main transmission module starts to send out digital signals through the optical wave of the light-emitting diode after receiving the wake-up instruction. The main receiving module is responsible for receiving the optical wave to generate digital signals and transmitting the digital signals to the host for parsing. According to the above links, during the battery charging process, the communication between the battery and the charging device can be carried out by optical wave. Since it is transmitted by optical wave, there will be no problem of signal loss due to line connection and line damage, resulting in inaccurate data. And this device is used in the field of shared battery swapping. The battery has a high usage frequency and frequent charging times. The positive and negative electrodes of the battery are connected by a large current through a plug for charging, but the internal data of the battery is transmitted through this device. In the market, communication is carried out by connecting the battery main board through wires. In this process, the integrity of the communication wires must be ensured, otherwise the communication will fail. Due to the frequent use in the field of shared battery swapping, the bending times of the charging plug wire are limited, and the internal communication wire is relatively thin, resulting in frequent breakage of the communication wire. While the positive and negative large current wires are thicker and have little impact, so two thick positive and negative wires are still retained at the plug part for charging, but the internal data of the battery is transmitted through this device for signal transmission, which requires wire connection transmission. The communication method in the existing market has a high damage rate. Every time it is damaged, it needs to be repaired. Without repair, the data situation of the battery cannot be detected, which is likely to affect the battery charging problem and the battery temperature sensing problem, and there may be potential safety hazards. Therefore, the problem of wire aging will not occur when using optical wave transmission signal. The optical wave is encoded into a signal transmission band, which can also achieve the function of wired signal transmission.

[0037] The working process of this device is that both the main transmission module and the main receiving module have the functions of sending and receiving optical waves. After the main receiving module is powered on for 1 second, it will send out optical waves through its own light-emitting diode A. At this time, the photosensitive diode A of the main transmission module receives the optical wave signal, which is amplified by the amplifier circuit A and calculated by the single-chip microcomputer A. This process is defined as the wake-up instruction process. After the main transmission module is awakened, it starts to send data. The single-chip microcomputer A of the main transmission module will send out the data to be sent through its own light-emitting diode A in the form of optical waves. At the same time, the main receiving module only responsible for continuously receiving optical waves through its own photosensitive diode B. The main receiving module will calculate the received optical waves through its own single-chip microcomputer B and convert them into binary digital signals, and then give them to the host.

[0038] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
