TECHNICAL FIELD
[0001] The present application belongs to the technical field of power distribution circuit system, and particularly relates to a charging and discharging device for a battery pack, and more particularly to an intelligent life buoy communication method, a communication system, and a computer readable storage medium. BACKGROUND
[0002] The working frequency band of the traditional power carrier is 3kHz-500kH, and the technical essence thereof is to "parasitically" generate a high-frequency carrier signal on a 50Hz power grid. However, such a high-frequency characteristic causes a double technical bottleneck in 2-10km long-distance transmission.
[0003] The high-frequency signal exponentially attenuates in the cable due to the skin effect and dielectric loss. The actual measurement data shows that the 3kHz signal attenuates by about 40dB in a 5km cable, and the 30MHz signal attenuates by more than 120dB, resulting in a signal strength at the end lower than the noise floor. At the same time, the high-frequency common-mode noise generated by the frequency converter, motor and other equipment has a completely overlapping spectrum with the carrier signal, which directly leads to a signal-to-noise ratio of less than-10dB.
[0004] At present, when the life buoy is put into the life buoy, the control system on the life buoy is connected to the control system on the life boat through a cable, and the communication between the life buoy and the life boat is realized by using the power carrier mode. However, water rescue needs to be fast and accurate, which leads to the fact that the life buoy cannot quickly and accurately reach the rescue position, and thus the rescue fails.

[0024] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0026] As used herein, the phrases "in an embodiment", "according to an embodiment", "in some embodiments", and the like, generally mean the particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of the present disclosure. Thus, appearances of such phrases in various places in the specification do not necessarily all refer to the same embodiment. As used herein, the terms "example", "exemplary", and the like, are used as examples, instances, or illustrations. Any implementation, aspect or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects or designs. Rather, the use of the terms "example", "exemplary", and the like, is intended to present concepts in a particular way.
[0027] It is found through research that the working frequency band of the traditional power carrier is 3 kHz-500 kHz, and the technical essence is to "parasitize" a high-frequency carrier signal on a 50 Hz power grid. This high-frequency characteristic causes a double technical bottleneck in 2-10 km long-distance transmission. The high-frequency signal exponentially attenuates in the cable due to the skin effect and dielectric loss. The measured data shows that the 3 kHz signal attenuates about 40 dB in a 5 km cable, and the 30 MHz signal attenuates more than 120 dB, resulting in a signal strength at the end lower than the noise floor. At the same time, the high-frequency common-mode noise generated by frequency converters, motors and other equipment has a frequency spectrum completely overlapping with the carrier signal, directly causing the signal-to-noise ratio to drop below -10 dB. At present, when the life-saving boat throws the life buoy, the control system on the life buoy is connected to the control system on the life-saving boat through the cable, and the communication between the life buoy and the life-saving boat is realized by using the power carrier mode. However, water rescue needs to be fast and accurate, which results in that the life buoy cannot quickly and accurately reach the rescue position, and further leads to rescue failure.
[0028] Based on the above research, the embodiment of the present disclosure provides an intelligent life buoy communication method, a communication system and a computer readable storage medium. By directly performing waveform cutting processing on the power supply output signal, the power supply output signal itself contains power adjustment information. At the same time, the power adjustment information is quickly and accurately extracted after the power supply output signal is analyzed, and then the corresponding pulse direct current signal is converted to quickly and accurately control the power life buoy to move on the water surface. The problems of unstable communication and poor communication quality caused by signal attenuation and noise of the traditional power carrier are overcome, the life buoy can be quickly and accurately guided to the rescue position, the fast and accurate demand of water rescue is met, and the rescue success rate is improved.
[0029] The above-mentioned defects are the results of the inventors after careful research and practice, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contributions of the inventors to the present disclosure.
