The Effect of Wind Velocity Recorder on the Application of Wind Resource Monitoring

<

The application of wind energy resources in power generation applications and applications in agriculture are very common. No matter which industry needs the correct assessment of the application of wind energy resources, it is necessary to install wind speed and direction recorders at some points. Record relevant data. In the past, traditional recording methods were recorded on paper, and the wind direction and wind speed were converted by humans. The workload of this method was very large and difficult to manage. The wind speed recorder is designed and applied to adapt to this long-term field record.

Using the wind speed and direction recorder, the wind speed and direction data collected by the wind speed and direction sensor can be recorded, and can be directly transmitted to the computer and processed by software. In addition, after some modifications, the recorder can also be used in the meteorological department. The recorder uses a single-chip computer technology. The uniquely designed power-saving circuit allows it to be powered by a battery and can be measured in the wild without a power grid. The commonly used EL-connected wind-wind recorder is required to replace the recording paper daily and must be There is AC power supply.

The wind speed recorder has large storage capacity and can take data every 3 months. The data can be input directly into the computer through the application port. In the field, the data can be retrieved with a matching data transcripter, and then input into the computer. The data processing is accurate. Rapidly, graphics processing is convenient and intuitive, greatly reducing the workload and operating costs. The processed data format is compatible with the existing wind farm evaluation software WASP and can be used in conjunction with a comprehensive evaluation of the wind farm. The anemometer is small in size, light in weight and easy to operate. The data transcription operation can be easily performed by connecting a single cable. The three-digit liquid crystal display can display the instantaneous wind speed, date and time at that time. The two buttons on the panel can be set. Date and time.

The wind speed and direction recorder measures the wind speed value every 105th, and averages the test values ​​(60 points in total) in lomin and then stores it into the external RAM as the actual wind speed value. In order to improve the reliability of the system, a series of anti-jamming measures were taken on the software. For example, the wind speed sampling value of each program is filtered; the instruction redundancy technique is used before some instructions that determine the flow of program flow; unused vector areas, unused ROM space, tables, and programs Software trap technology is used at the breakpoints, etc. Once a chaotic program is found, it immediately enters a power-off state to ensure that the stored wind speed value is not destroyed. Tl has dual functions in this system. On the one hand T. , T, as the general I/O port detection button is pressed; but when measuring wind speed, T. T, are used as timers, where T. By INT. The gated, test wind speed signal cycle high time, Tl used to limit the test time, so as not to be in the wind state, the program has been in the test state and enter the infinite loop.

The application of wind speed and direction recorder has greatly reduced the work of the inspectors, and the monitored results are more accurate and scientific, providing a scientific basis for the formulation and implementation of agricultural cultivation measures, and also an important reference for the application of wind resources. The development of new energy has very important auxiliary significance.
