Problems solved by technology
[0004] 1. In safety monitoring, conventional sensing devices are usually used to monitor the temperature of marine shore power boxes, transformers, and power compensation modules. The sensing monitoring points are fixed, the sensing method is single, and the heating range of monitoring is small. It is difficult to take into account the heating of equipment , connector ignition, fire and other equipment safety hazard monitoring;
[0005] 2. The power compensation strategy is directly generated by the marine shore power system located on the ship according to the working status and parameter information of the marine equipment, which cannot take into account the operating status information of the shore power grid system, so it is difficult to obtain the best power compensation strategy, which is not conducive to the overall system. reliable operation

Embodiment Construction
[0020] The multi-band visual perception module structure of the embodiment of the present invention is as follows: figure 2 As shown: an ultraviolet array sensor 1, a visible light image sensor 2, and an infrared thermopile sensor 3 are placed sequentially from top to bottom, and there is a black ABS spacer layer 4 between the sensors. The models of the three sensors are: GT-ABC-L, PIXIS scientific grade CCD detector, HMS J11 F5.5. Such as image 3 As shown, each sensor is individually connected to a vertical rotating shaft 5, so each sensor can be rotated independently, and the light intensity of the wavelength band automatically aligns the center of the field of view with the target, and the plane rotation range is ±30º. The data post-processing module adopts ARM+DSP dual-core structure (ARM model: STM32F4XXX, DSP model: DM6XXX). ARM core load module initialization self-test, data acquisition, IEC61850 protocol conversion, data upload, horizontal rotation axis control. D...

The invention relates to a control system for a ship electric power system, and in particular relates to a shipborne shore power safety system based on visual Internet of Things and a power compensation method. The system comprises groups of multiband vision sensing modules used for monitoring a shipborne shore power box, a transformer and a power compensation module. Each group of multiband vision sensing module comprises an ultraviolet array sensor, a visible light image sensor and an infrared thermopile sensor, wherein three independent sensors are arrayed. The change of infrared ray, visible light and ultraviolet radiation of a measured location can be monitored. The shipborne shore power safety system based on visual Internet of Things and the power compensation method can be applied to high and low voltage shore power devices of the existing ships, and have the advantages of high integration degree, high utilization rate of electric energy, optimized monitoring, strong expansibility, safety and reliability.
Description
technical field [0001] The invention relates to a control system of a ship power system, in particular to a ship shore power safety system and a power compensation method based on the visual internet of things. Background technique [0002] Ship shore power means that the ship stops using the generator on board during berthing, and the ventilation, lighting, refrigeration and other facilities on the ship are powered by the wharf, thereby reducing the ship's exhaust gas emissions. The shore power system is mainly composed of the port substation, shore power supply device, shore power receiving device and cable connection equipment. Ship shore power supply can be divided into high-voltage shore power system and low-voltage shore power system according to different voltages. The high-voltage shore power system mainly refers to the shore power system whose output is 6.6kV / 11kV or above. For large ships, the load of various electrical equipment on board is heavy, and medium and ...
