Description

Technical Field

[0001] The utility model relates to the field of building renewable energy system monitoring, in particular to a portable building renewable energy system monitoring tool and a monitoring system. Background Art

[0002] Building renewable energy systems are widely used and diverse in form. Meteorological environmental parameters such as solar irradiance, temperature, wind speed, wind direction, and atmospheric pressure, as well as parameters of the heating and cooling systems such as flow, temperature, cooling and heating power, voltage, and current are important indicators of building renewable energy systems. Real-time, on-site, and accurate measurement, collection, and analysis of the above data are very important for monitoring the operating status of the system, promptly troubleshooting and handling problems, and guiding the adjustment of operating strategies.

[0003] In general, renewable energy systems in buildings do not have a monitoring platform, so users cannot conduct real-time monitoring and analysis. For the monitoring platforms that have been installed, the existing environmental parameters and system parameters are mostly collected by standard signals output by sensors, which need to be calculated and converted according to the type, signal and range of the sensor, and transmitted to the host computer through the communication protocol. The collection systems for different types of parameters are relatively independent and arranged in a scattered manner. The monitoring of existing systems mostly relies on pre-built integrated monitoring platforms to uniformly summarize and manage the scattered sensor monitoring systems, and the types of signals collected by all interfaces are pre-defined. For example, the flow interface can only monitor flow, and the temperature interface can only monitor temperature, which cannot be flexibly adjusted. At the same time, the project site conditions are complex and changeable, and the parameters that need to be collected vary greatly from project to project. Existing tools cannot adapt well to on-site needs. Specifically, it is reflected in:

[0004] Existing tools require an external power supply, and their use places are subject to certain restrictions. They cannot be used in places without electricity supply, or they need to set up long power lines separately when using them. They cannot adapt to the complex environment needs of the test site; most of the existing tools limit certain specific parameters that they can monitor, and they cannot instantly access new parameters according to actual scenarios and monitoring needs, and their versatility is poor; the number of channels of existing tools is limited, and the types of monitored measurement points and data are limited. They are not suitable for monitoring projects with large sites, many measurement points, and a wide range of data types; existing tools can display some data, but cannot integrate a large amount of collected data on site, and cannot conduct data analysis simultaneously. They often need to export data uniformly after leaving the site and then analyze them, and their timeliness is poor.

[0005] Therefore, the objective shortcomings of the prior art are as follows:

[0006] 1. Strong dependence on external power supply;

[0007] 2. The types of monitoring parameters are fixed and new parameters are not applicable;

[0008] 3. The number of monitoring parameters is limited;

[0009] 4. No data analysis function;

[0010] 5. Data storage is inconvenient, the built-in storage space is small, and data transfer is troublesome;

[0011] 6. The user needs to install special data reading software on the computer, which requires a high level of professionalism from the user;

[0012] 7. The collector is inconvenient to set up and the steps are complicated.

[0013] It can be seen that the above existing building renewable energy system monitoring tools still have inconveniences and defects in structure and use, and are in urgent need of further improvement. How to create a new building renewable energy monitoring tool has become a goal that the industry needs to improve. Utility Model Content
