Wireless wind speed tester

Abstract

The invention discloses a wireless wind speed tester. A tester body is internally comprises provided with a single-chip microcomputer, a wind speed inquiry module, a wind speed storage module, a power module, an under-current adjustment module, a wireless receiving module and a display module, wherein the single-chip microcomputer is connected with the wind speed inquiry module, the wind speed storage module, the power module, the under-current adjustment module, the wireless receiving module and the display module respectively. A measurement device at a measurement position transmits measured data to the single-chip microcomputer in a ZigBee wireless manner and stores the data in the wind speed storage module; the data in the wind speed storage module can be called by inputting a signal into the single-chip microcomputer though the wind speed inquiry module, and can be displayed through the display module, so that the real-time wind speed monitoring of each anemograph is facilitated, and wind speeds at a plurality of positions can be detected at the same time; therefore, the calculation accuracy is effectively improved; manual measurement is not needed, the working safety is guaranteed, and the labor intensity is relieved; when the electric quantity is too low, a light emitting diode transmits a pre-warning signal to let a user know and handle with the situation immediately.

Description

technical field [0001] The invention relates to a test instrument, in particular to a wireless anemometer. Background technique [0002] In mine production, the ventilation system is responsible for conveying fresh air underground and discharging harmful gases underground, which is an important guarantee for efficient and safe production. Therefore, it is necessary to regularly measure the performance of the ventilator to ensure the efficient and safe operation of the ventilation system. In the fan performance test, the air volume is a very important index. The existing method is usually to arrange the operating points on the wind measuring section, measure the wind speed of each point one by one through the anemometer, record it, and then calculate the required parameter. In mines, on the one hand, the test environment is relatively harsh, and it is difficult to ensure the safety of recorders; Due to the time difference, the accuracy of the final calculated air volume is ...
