Embodiment 1

[0020] The implementation principle of the large dynamic range communication method in this embodiment is to change the low-level pulse width of the laser codec module in real time at a certain communication rate according to the agreed communication protocol. Such as figure 1 As shown, the method for realizing efficient communication of portable laser communication equipment at a certain communication rate includes communication protocol agreement, sampling frequency agreement and data transmission encoding, receiving decoding.

[0021] (1) The communication protocol of the laser codec module includes start bit, data bit and stop bit: the start bit is a low level with a specific width, the data bit can be any bit, and the high level pulse width of the data bit is fixed, changing The position of the high level in the cycle realizes that the duty cycle of the corresponding bit is different, and the data represented is different, and the stop bit is a high level with a specific ...

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a high-efficiency data communication method of a portable laser communication device, which is used for improving signal bandwidth under the condition of fewer signal lines. Background technique [0002] In the communication of the existing portable laser communication equipment, a baud rate is usually agreed upon by the laser coding and decoding modules of both parties, and bit-by-bit transmission is realized at a specific baud rate. The communication method is widely used in the communication field due to its simple implementation and convenient operation. [0003] The commonly used method is to set a start bit at the beginning of the signal, followed by setting the data bit (6 bits, 7 bits or 8 bits), and the stop bit. This communication method has a small dynamic range. When the signal bandwidth is high, It will cause signal attenuation or increase resource occupation. I...
