Problems solved by technology

[0006] Due to wind blowing or other reasons, the fan will vibrate slightly, causing the received signal to swing from side to side near the receiving end, and will also generate a series of pulses, making the fault monitoring make wrong judgments

[0035] When using this unit, first set the image 3 The coded disk A and coded disk B shown are set on the shaft of the fan shaft head shown in Figure 4, and the outer edges of coded disk A and coded disk B are adjusted so that the coded disk A and coded disk B are staggered to form a certain width. Gap, the diameter of the outer edge of the encoding disc A and encoding disc B is 80mm, so that the width of the outer edge gap is 15mm, and the photoelectric sensor A and photoelectric sensor B are placed in parallel so that the sensor sensing contacts are facing the encoding disc A and encoding disc B. On the side of the scale line, make the distance between photoelectric sensor A and photoelectric sensor B 8mm smaller than the corresponding notch width.

[0036] Calculate the angle of the notch through the scale value, and calculate the ratio of this angle to the angle of the non-notch part of the outer edge of the code disc as 1:4;

Abstract

The invention discloses a fault monitoring device and a fault monitoring method for a frost-proof fan in a tea garden and an orchard. The fault monitoring device comprises a programmable controller, an alarm, a GSM (Global System for Mobile) module, a power supply module, a photoelectric sensor A, a photoelectric sensor B, a coding disc A and a coding disc B; the coding disc A and the coding disc B are arranged on a spindle head of a motor for driving the fan in a sleeving manner and the coding disc A and the coding disc B are enabled to be staggered and are screwed down by a nut; the photoelectric sensor A and the photoelectric sensor B are fixed on a cradle head for supporting the motor; induction contacts of the photoelectric sensor A (3) and the photoelectric sensor B (4) are enabled to be perpendicular to the surfaces of the coding discs, which are provided with scales, side by side; the input end of the programmable controller is connected with the output ends of the photoelectric sensor A and the photoelectric sensor B; the programmable controller controls the alarm and the GSM module to carry out fault alarm of the frost-proof fan and send fault information according to processing results of signals output by the photoelectric sensor A and the photoelectric sensor B; the fault monitoring device and the fault monitoring method are convenient to timely find the fault of the fan to carry out maintenance, ensures normal operation of frost-proof equipment and ensures a frost-proof effect. The fault monitoring device and the fault monitoring method can be applied to fault monitoring of the frost-proof fan in the tea garden and the orchard.

Description

technical field [0001] The invention belongs to the field of agricultural machinery equipment, and in particular relates to an automatic fault monitoring technology of a frost-proof fan in a tea garden. Background technique [0002] Frost damage has always been a key factor restricting the production of famous and special teas in early spring in southern my country and the stable increase of tea farmers' income. Traditional anti-frost measures in tea gardens are time-consuming and labor-intensive, and even affect the quality of tea and pollute the environment. In recent years, the anti-frost fan technology for tea gardens imported from abroad uses fans to prevent frost in tea gardens, which overcomes these shortcomings. The anti-frost effect is good and the maintenance is convenient. And it is conducive to the improvement of tea quality, and can achieve a more ideal effect. Tea garden anti-frost fan technology is a new anti-frost technology introduced from abroad in recent ...
