Wireless indicator, wireless indicator system and indicator diagram measuring method thereof

Abstract

The invention discloses a wireless indicator mounted on a pumping unit based on laser distance measurement for receiving and sending data with a remote control system for drawing indicator diagrams, a wireless indicator system and an indicator diagram measuring method thereof. The wireless indicator comprises a laser displacement sensor, a pressure load sensor, an acquiring amplification module, a core processing module and a wireless communication module, wherein the laser displacement sensor emits laser to measure the vertical displacement with the ground to output a displacement value. The wireless indicator of the invention directly measures the displacement by the laser displacement sensor, so that the influence from the vibration of the pumping unit is small, the precision of the indicator diagrams of the wireless indicator is improved, and the troubles of the existing indicators incapable of well measuring large stroke and under stroke of the pumping unit are solved. The wireless indicator system has at least one wireless indicator respectively mounted on different pumping units for respectively acquiring data of a plurality of oil wells to send to the remote control center to realize the area networking measurement.
