Automated weather station system with fault self-diagnostic and self-recovery function

Abstract

The invention discloses an automated weather station system with a fault self-diagnostic and self-recovery function, and belongs to the technical field of automated weather stations. The automated weather station system with the fault self-diagnostic and self-recovery function comprises n weather stations and a remote control terminal, wherein n is a positive integer, and each weather station comprises a microcontroller, a collector and a communication module; the collector is externally connected with a power supply, and a comparator circuit is arranged inside the remote control terminal; when a certain weather station in the n weather stations is subjected to detection diagnosis, the data average value of (n-1) weather stations other than the detected weather station is used as a reference value; and when the difference of the weather data of the detected weather station and the reference value exceeds the preset deviation range, the fault of the collector of the weather station is diagnosed. The automated weather station system provided by the invention can diagnose a fault source by self, shorten downtime, improve the work efficiency of the weather station, reduce data error, and enhance real-time detection accuracy and stability.

Description

technical field [0001] The invention relates to a technique for automatic weather systems, and belongs to the technical field of automatic weather station systems with fault self-diagnosis and self-recovery functions. Background technique [0002] At present, the automatic weather stations used in my country have generally adopted automatic weather stations, but the existing automatic weather stations have poor stability. There are two main reasons for this, one source is sensor failure, and the other source is collector failure. The sensor has been used in the field for a long time, and some are even used in areas with harsh environments. Failures will inevitably occur. There are two common sensor failures. One is long-term sensor failure damage. There will be maximum or minimum values; the other is short-term sensor failure damage, such as leaves, soil, rain, etc. falling on the sensor, which will cause deviations in the output value of the sensor. The fault of the collec...

[0002] At present, the automatic weather stations used in my country have generally adopted automatic weather stations, but the stability of the existing automatic weather stations is poor. There are two main reasons for this, one source is sensor failure, and the other is collector failure

The sensor has been used in the field for a long time, and some are even used in areas with harsh environments. Failures will inevitably occur. There are two common sensor failures. One is long-term sensor failure damage. There will be a maximum or minimum value; the other is short-term sensor failure damage, such as leaves, soil, rain, etc. falling on the sensor, which will cause the output value of the sensor to deviate

The failure of the collector is mainly due to the fact that the collector does not work as a whole

Due to these small faults, the existing automated weather stations cannot realize the functions of self-diagnosis and self-recovery, poor practice, low efficiency, and need someone to be on duty for a long time
