Embodiment Construction

[0040] As far as a wind power generation site is concerned, there are multiple wind turbines forming a power generation area, and a corresponding number of data acquisition systems are required to collect the speed of each fan. Therefore, the overall concept and design plan uses multi-point acquisition to measure the speed of each fan, such as figure 1 As shown, the present invention installs a fan speed data acquisition device on each fan assembly, and forms a many-to-one communication network with the main control station.

[0041] The invention includes a plurality of fan speed data acquisition devices and a main control station,

[0042] like figure 2 As shown, the fan speed acquisition device includes a speed measurement sensor, a microcontroller 1 , a power supply module and a wireless transceiver module 1 .

[0043] The rotational speed measurement sensor is used to measure the rotational speed of the fan blade of the wind power generator. As a preferred solution of ...

Abstract

The invention relates to the field of rotational speed measurement, in particular to a draught fan wireless velocity measurement system. The draught fan wireless velocity measurement system comprises a plurality of draught fan rotational speed data acquisition devices and a master control station, wherein each draught fan rotational speed data acquisition device comprises a rotational speed measurement sensor, a microcontroller 1, a power module and a wireless transceiver module 1, and the master control station comprises a microcontroller 2, a display module and a wireless transceiver module 2. According to the draught fan wireless velocity measurement system, the wireless transmission is adopted, the input is low, the wiring is not necessary for transmission, the transmission speed is fast, the anti-interference performance is higher, the adaptability is good for working environment, and the special production environment is applicable. By means of a non-contact switch-type Hall sensor, the consistency is good, the sensitivity is high, the circuit power is low, and the Hall sensor can be connected with various logical circuits directly.

Description

technical field [0001] The invention relates to the field of rotational speed measurement, in particular to a wireless rotational speed measurement system of a fan. Background technique [0002] In modern production and life, along with people's development of wind energy, wind power generation technology has become increasingly mature, and its application has gradually become widespread. Wind power generation is the process of converting mechanical energy into electrical energy, and the source of mechanical energy for wind turbines is the natural wind. The size of the wind force is determined by natural factors, and the size of the wind force determines the rotation speed of the wind turbine. When the wind is strong, the speed of the fan is correspondingly relatively large, because the bearing capacity of the fan is limited. If the wind is too strong and the speed of the fan is too high, it may cause damage to the fan components (such as the shaft, fan blades, etc.), which...
