Intelligent heating type cold-resistant meteorological sensor

Abstract

The invention relates to an intelligent heating type cold-resistant meteorological sensor, and aims at improving the external structure of a present sensor and introducing an automatic cold-resistance storage type mechanical structure intelligently. The position relation between a first bushing (2) and a second bushing (3) is designed, so that a storage type accommodating and protecting cavity is formed, and a heating cavity (12) used for temperature-control protection for a metrological sensor body (1) is formed. An external temperature detector is used to realize real-time accurate detection for the external ambient temperature, and an electric heating driving circuit (14) is arranged to realize intelligent control for an electric control telescopic rod (6) and a heater body (9). Thus, the metrological sensor body (1) is input / output relative to the storage type accommodating and protecting cavity, and the metrological sensor body (1) is effectively protected while working normally.

Description

technical field [0001] The invention relates to an intelligent heating type cold-resistant meteorological sensor, which belongs to the technical field of sensors. Background technique [0002] A sensor (English name: transducer / sensor) is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the information requirements. The requirements of transmission, processing, storage, display, recording and control; the characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. Usually according to its basic perception function, it can be divided into ten categ...

Problems solved by technology

[0005] As can be seen from the above prior art, the various sensors of existing designs provide a lot of convenience for people's lives, making the actual use more humanized, but in actual use, careful people can always find some Unsatisfactory places, as we all know, meteorological sensors are used to detect meteorological parameter data information, and are often set in some harsh environments, such as highlands or cold locations, which put forward strict requirements on the sensor itself, but in addition On the one hand, due to the accuracy requirements of meteorological data collection, highly sensitive detection components need to be used, which makes it difficult for the sensor to cope with harsh environments for a long time and affects the normal use of meteorological sensors
