A dual-axis transmission line tower tilt sensor

Abstract

The invention discloses a double-shaft transmission lien tower inclination sensor, which comprises a housing and is characterized in that one end of the housing is connected with an installation base; a transmission circuit board and a sensor circuit board are disposed inside the space formed by the housing and the installation base; one end of a cable conductor passes through the other end of the housing and is connected to the transmission circuit board; and the other end of the cable conductor is connected with a data collector. The sensor provided by the invention is compact in structure and small in size, and has strong anti-electromagnetic interference capability; while working on site, solar sheets are used to supply power for the data collector; the sensor needs no power supply atordinary times, but when in need of a measurement, the data collector firstly supplies powder for the sensor and then a measurement command is issued for measuring, thus effectively reducing the power consumption. By the adoption of an MEMS device, two orthographic direction inclination angles can be simultaneously tested; in addition, the temperature compensation design of the transmission circuit board is carried out so as to eliminate the influence of temperature on measurement precision and enable the sensor to adapt to the influence of complex climatic conditions. Therefore, the sensor provided by the invention can be used to accomplish the automatic acquisition of tower inclination data.

Description

technical field [0001] The invention relates to a sensor and belongs to the technical field of detection. Background technique [0002] With the rapid development of the economy, especially the intensification of the mining of mineral resources, the area of ​​the goaf formed in the mining area has gradually expanded, making the transmission line towers on the ground in the goaf easily inclined or even collapsed. In fact, it is bound to cause the occurrence of serious and extraordinarily serious safety accidents in the power ring network, which will bring great losses to the country. Due to the large number of transmission line towers, there are many factors for the inclination of the towers, and the range is relatively wide. It is difficult to detect the inclination of the towers in a timely and accurate manner only by the daily inspection of the transmission line patrol personnel. Therefore, it is very important to quickly determine the inclination and collapse of the tran...

Problems solved by technology

At present, laser or far-infrared methods are often used in foreign countries for real-time monitoring of towers. The advantage is high precision, and the disadvantage is that there are many devices on a single tower, and a single power line is used to supply power to the device, and the measurement accuracy is often affected by weather conditions (rain, fog, etc.) etc.) impact

Manual inspection or inspection is mostly used in China. The disadvantage is that the inspection cycle is long and the accuracy is low, especially in remote mountainous areas or forest areas. The slow tilt or collapse of the tower cannot be detected and dealt with in time.
