Small weather stations should be assigned a person to manage and regularly check the weather station, and also to prevent pests, because the sensors of the weather station are processed and collected on the collector and displayed on the computer, if the rats chew the cable, it is not only inconvenient to repair, but also the data of the sensors on the weather station can not be accurately transmi···
For agricultural weather stations, sensors are very important and have high accuracy and reliability. The weather station equipment is generally used continuously year after year, in daily use, how should the agricultural weather station maintenance and maintenance?
it is necessary to strengthen the training of managers' skills related to the use of agricultural environment, and to identify the instruments in time to improve the efficiency of the use of agricultural weather stations.
Meteorological station rain gauge data abnormal causes.Residual rainwater: The equipment commonly used for precipitation data monitoring is the tipping bucket rain gauge. The tipping bucket is the part of the rain gauge that collects rainwater, but if there is a part of residual rainwater in the tipping bucket, it will make the precipitation data have a small deviation.
Reasons for abnormal data: Wind speed data problems are generally the cause of the poly-carbon wind speed sensor, poly-carbon wind speed sensor using mechanical structure design, there are rotating parts, so there is a minimum wind speed before monitoring as a start condition, if the wind speed is lower than the start value will not be able to drive the propeller or wind cup for rotation, it will ···
How to install the soil sensor:Quick measurement method:(1) Choose a suitable measurement location and avoid clods;(2) According to the measured depth, plan the topsoil;
Soil moisture sensor operation precautions:1. Before the measurement, the soil with uniform density should be selected as the measured object;2. Do not insert the sensor probe into the hard soil block to prevent the probe from being damaged;
4G RTU integrates traditional industrial RTU and full Netcom/4G/3G/5G data transmission functions into one, realizing comprehensive functions such as collection, counting, control, storage, alarm and transmission. It is also compatible with the data transmission function of the full Netcom/4G/3G/5G IP MODEM.
In the architecture of the Internet of Things, an intermediate device is needed between two different networks at the perception layer and the network layer, that is, the "Internet of Things Gateway". The IoT gateway can be used for both wide area network interconnection and local area network interconnection. In addition, the IoT gateway also needs to have device management functions. Operators c···
After GPRS DTU is powered on, first read the working parameters stored in the internal FLASH (including GPRS dialing parameters, serial port baud rate, data center IP address, etc., which have been configured in advance).
