AI Technical Summary

Technical Problem

There is a difference between the mechanical indication and the remote transmission signal of the existing remote density meter, resulting in low observation efficiency and large errors. Especially in locations that are inconvenient for observation, manual auxiliary equipment is required, and the acceptance process is time-consuming and labor-intensive. The high-cost drone or robot system is not suitable for use in old stations.

Method used

By setting an angle sensor in the density meter to convert the pointer movement trajectory into an electrical signal, combined with the processing module and infrared receiver, automatic reading and voice broadcast of the dial indication can be achieved. The magnetic encoder and strong magnetic sheet are coaxially set up and combined with the MCU processor to perform data calculation and output.

Benefits of technology

It realizes automatic reading of dial indications in inconvenient observation positions, reduces observation errors, and improves efficiency. It is suitable for low-cost improvement of old stations.

Abstract

A sulfur hexafluoride remote transmission type density meter capable of automatically reading dial reading belongs to the field of instruments and meters and comprises a movement spindle and a mainboard. A processing module is arranged on the mainboard; the device is characterized by further comprising an angle sensor. The angle sensor comprises a strong magnetic sheet and a magnetic encoder; the magnetic encoder is arranged on the main board; a bracket is arranged on a main shaft at the tail end of the machine core main shaft; and the strong magnetic sheet is arranged on the bracket. By improving the existing remote transmission type density meter, the angle sensor is arranged to conveniently convert the motion trail of the pointer into an electric signal, and then the electric signal is output through the remote transmission module, so that the acquisition and subsequent comparison of the reading value of the meter and the density value of the sensor system can be conveniently realized; and meanwhile, by arranging the infrared receiver and the loudspeaker, the reading of the meter dial plate is broadcasted by voice on site by utilizing an infrared induction principle on site, the reading of the meter pointer is conveniently obtained at a ground position which is inconvenient to observe, the cost is low, the precision is high, and the meter is suitable for popularization and application.
