Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic data analysis, and in particular to an emergency warning device and a control method thereof. Background Art

[0002] In the emergency warning industry, the equipment is installed outdoors. In most cases, there is no mains power supply. Basically, the emergency equipment is powered by photovoltaic panels + batteries. The data collected by the sensors is transmitted to the cloud platform through the RTU of the emergency equipment. The RTU requires the sensors to work 24 hours a day, and the equipment is powered by a combination of photovoltaic panels and batteries. However, most of the current emergency equipment products have relatively simple management of power supply and power consumption. In various extreme outdoor conditions, in order to maintain the 24-hour long battery life of the equipment, it is achieved by increasing the area of ​​photovoltaic panels and the capacity of batteries. This will increase the overall cost of the product, the difficulty of installation and construction, and the operation and maintenance cost of the equipment.

[0003] At the same time, the RTUs in most emergency warning devices do not have energy management functions, but only data collection functions, and cannot analyze environmental information, equipment battery power, and current working conditions. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that power supply and power consumption are currently managed by increasing the area of ​​photovoltaic panels and batteries, which increases product costs and real-time operation and maintenance costs, and that the existing RTU does not have energy management functions and cannot analyze environmental information, equipment battery power, and current working conditions, and to provide an emergency warning device and a control method thereof.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0006] An emergency warning device comprises: a sensor module, a photovoltaic panel module, and a storage battery. The photovoltaic panel module comprises: a photovoltaic panel, a main control device, and a cloud platform. The cloud platform and the sensor module are communicatively connected with the main control device. The photovoltaic panel and the storage battery are electrically connected with the sensor module.

[0008] The cloud platform is used to analyze and judge the field data, the power generation voltage data and the power data, and to control the collection frequency of the sensor collection module and the sending frequency of the main control device.

[0009] By adopting the above technical solution, a cloud platform is added to analyze and judge the field data, battery power, and photovoltaic panel voltage, so as to realize automatic management of the energy consumption of the device, minimize the power consumption of the device, ensure that the equipment is online 24 hours a day, and can collect on-site monitoring data in real time. In the event of an emergency, the on-site monitoring data can be obtained in real time. In the same application scenario, the battery capacity and photovoltaic panel area, as well as the size of the supporting structural support parts, are reduced; the cost of the product and the difficulty of installation and construction are reduced; at the same time, since the size of the photovoltaic panel is reduced, the wind resistance of the product outdoors is reduced, and the operation and maintenance cost of the equipment is reduced.
