Description

Technical Field

[0001] The utility model relates to the technical field of signal monitoring, in particular to a solar power supply system. Background Art

[0002] At present, the demand for safety monitoring is increasing. Bridges, dams, roads, slopes, etc. all need safety monitoring to ensure the safety of facilities and personal property. Most places are difficult to have electricity supply conditions. Long-term monitoring can only use solar power supply systems to ensure the operation of equipment. Some areas have more rainy and cloudy weather, and some projects have more equipment installed, which will cause the traditional solar power supply system to have too much power supply pressure. Blindly adding solar panels or batteries will increase the cost. If solar panels or batteries are added on site later, the manpower and material costs will be further increased. When using the charging controller of the traditional solar charging system, you need to manually select the battery type, or select the controller that matches the battery in advance, otherwise it will greatly affect the charging efficiency, which is also a defect of the traditional solar power supply system.

[0003] Therefore, it is an urgent problem for those skilled in the art to propose a solar power supply system to solve the problem that the existing technology relies on human resources and has low charging efficiency. Utility Model Content

[0004] In view of this, the utility model provides a solar power supply system, which can achieve the effect of balancing power saving and data collection frequency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A solar power supply system includes a solar panel, a light intensity sensor, a charge and discharge controller, a storage battery and a management module;

[0007] The light intensity sensor is arranged on the surface of the solar panel, the power supply end of the light intensity sensor is electrically connected to the discharge port of the charge and discharge controller, and the signal end of the light intensity sensor is connected to the signal input end of the charge and discharge controller;

[0008] The solar panel is electrically connected to the charging port of the charge and discharge controller;

[0009] The battery is connected to the charge and discharge controller;

[0010] The management module is connected to the input / output communication terminal of the charge and discharge controller.

[0011] In the above system, optionally, the light intensity sensor adopts a BH1750 sensor.

[0012] In the above system, optionally, the light intensity sensor is connected to the charge and discharge controller via an I2C interface.

[0013] In the above system, optionally, the charge and discharge controller includes an MCU module, a CN3795 charge management chip, an LTE module and a solid-state relay;

[0014] Both the LTE module and the solid-state relay are connected to the MCU module.

[0015] In the above system, optionally, the LTE module adopts the air724 module.

[0016] In the above system, optionally, the management module includes a data center and a management platform;

[0017] LTE module communication connection between data center and charge and discharge controller;

[0018] The management platform is connected to the data center for communication.

[0019] In the above system, optionally, the data center is a cloud server and the management platform is a customer management terminal.

[0020] In the above system, the battery module can optionally use a lithium battery, a lithium iron phosphate battery or a lithium titanate battery.

[0021] It can be seen from the above technical solutions that compared with the prior art, the utility model provides a solar power supply system with the following beneficial effects: 1) The utility model greatly reduces the power consumption of the equipment by controlling the power output and shutdown time, which can effectively alleviate the power supply pressure of the solar power supply system. The matching solar panels and batteries do not need to be particularly large to cover most application requirements, effectively reducing material costs; 2) The light intensity sensor of the utility model can let the user know the on-site environment. When the on-site sensor is offline, it can conduct a preliminary investigation to see if it is a power supply problem. It can also modify the power supply mode according to the on-site environment to achieve a balance between power saving and data acquisition frequency; 3) The CN3795 charging management chip of the utility model can charge the battery in the battery maximum power point tracking mode (MTTP mode). The user does not need to consider the battery type, reducing the problem of low charging efficiency due to incorrect battery type selection. BRIEF DESCRIPTION OF THE DRAWINGS

If the light conditions are average, the sensor can be powered for 5 minutes every 6 hours, and the power output can be turned off after the collected data is uploaded.
