Rain recorders are often used with rain sensors to detect, display, and store rainfall and rainfall. The recorder uses micro-power chips and circuits, the whole machine is more energy-saving, and the battery is powered by the battery. It is very convenient to use; the high-quality memory chip is used for fast data reading and large storage capacity. With LCD screen, you can view real-time data at any time. The appearance of rain-proof aluminum shell can effectively block the rain and ultraviolet radiation, and prevent the instrument from aging quickly in the harsh environment.
At present, the average station distance of China's surface meteorological observation stations is more than 50km, and the precipitation scale of less than 50km is basically not observed, which makes us unable to know the detailed structure of ground precipitation. To meet this demand, a number of self-recording rain gauges have been installed in many places to measure rainfall. Through the measurement and comparison, the following conclusions are drawn:
During the data acquisition process using the rainfall recorder, most of the rainfall recorders work normally, and the collected rainfall data is basically reliable. The rain gauge data is basically consistent with the groundwater station observation precipitation data. However, there are still some problems in the hardware of the data collection process in the individual rain gauges. The entire rainfall acquisition system still has problems such as clock errors and data acquisition failures. The data acquisition software is not very stable, and some functions are not perfect. These problems are mainly due to the fact that the rain gauges are not regularly inspected and maintained to ensure their normal operation; and there is no need to improve the data acquisition software. Therefore, as long as the rain gauge is regularly inspected and maintained, and the data acquisition software is improved, the rain data collection can be smoothly carried out and the data collected correctly, so that the rain gauge can be better applied to actual business and scientific research. in.
After the power is cut off, it is saved in the rain recorder, and the data in the self-recording rain gauge main unit is not lost. At the same time, the computer software has a powerful data processing function, and the rainfall recorder can form a graph and display it visually. The collected data can also be stored as an EXCEL spreadsheet file, which is convenient for users to save and process data, or use special software for data processing, drawing bar graphs, pie charts, printing, and the like. The software is permanently upgraded for free.
With AC and DC, you can take the field to measure the data at any time, and you can also place the recording location for a long time. It can be set to the computer lock mode. At this time, the interval set by the computer is automatically sampled to ensure the authenticity and continuity of the data. Up to 300,000 pieces of data can be saved. The rainfall recorder has become a very important step in the history of hydrological monitoring, representing the progress of this moisture monitoring. Since the introduction of the rainfall recorder, it has been well received by various observatories and research institutes, and it also provides a very convenient way for rainfall monitoring.
Daily maintenance and maintenance of the rainfall recorder:
This instrument is a sophisticated electronic product. Proper maintenance and maintenance can help protect the performance of the instrument and extend the life of the instrument. Please note the following:
1. Please use the instruction manual according to the requirements of the instruction manual. If the payment is incorrect, the instrument may be damaged.
2. Do not wipe the instrument with volatile liquid. Otherwise, the instrument may be discolored and deformed; wipe with a soft cloth to avoid scratching the external protective film of the instrument and prolong the service life of the instrument.
3. The instrument should be handled gently and should not be dropped or stressed. Otherwise, the instrument will be deformed and the internal circuit board will be damaged.
4. Do not touch the sensing part while the instrument is energized to affect the volume result or cause damage to the internal circuit of the instrument.
5. Do not disassemble and modify the instrument without permission to avoid damage to the instrument.
6. Use the screws firmly to fix the instrument when it is used, otherwise it may damage the instrument.
7. Check the power supply voltage of the instrument regularly to ensure the normal operation of the instrument.
