Problems solved by technology

[0004] There are many existing speed measurement technologies, but the transmission data needs to be transmitted through an intermediary device, which is inconvenient for data transmission and poor in real-time; each monitoring system has a small adaptability; installation and debugging are very troublesome; often the cost is very expensive; It will be very troublesome; and currently the smartphone does not have the function of measuring the rotational speed

Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] Such as image 3 and Figure 4 As shown, the specific steps of the method for measuring the rotational speed of the smart phone of the present invention are as follows:

[0042] 1) A cursor is set on the rotation axis of the measured object, and the flashlight of the mobile phone is set to flash against the rotation axis of the measured object at a certain frequency;

[0043] 2) Utilize the camera function of the mobile phone to take pictures to obtain the rotation diagram of the rotation axis of the measured object;

[0044] 3) Use the camera to open the picture function to open the picture of the rotation axis rotation picture;

[0045] 4) Use the image and data processing functions of the smart phone to process the image, and calculate the rotational speed according to the distance between two adjacent cursor points in the photo and the radius of the rot...

Abstract

The invention relates to a method for measuring rotating speed by using a smart phone. The method comprises the following steps of: setting a cursor on the rotating shaft of a detected object, setting the flashlight of the phone to enable the flashlight to flash towards the rotating shaft of the detected object according to certain frequency, photographing to obtain rotation pictures of the rotating shaft of the detected object by using the photographing function of the phone, and processing a data stream to obtain the rotating speed. The phone directly transmits the rotating speed to a control room in a wireless transmission way and the control room gives out a new command according to the obtained result; and the phone receives the command and controls an adjusting device to adjust the rotating speed of the detected object.

Description

Technical field: [0001] The invention belongs to the fields of industry and civil use, and in particular relates to a method for measuring a rotating speed by a smart phone. Background technique: [0002] The operation process of the existing industrial system online monitoring technology is as follows: figure 1 As shown, it includes the following steps: firstly collect the on-site physical quantities through a professional data collector to obtain the data stream; then transmit the data stream to the control room through the corresponding transmission line and intermediary transmission device; call a special processor in the control room to analyze and process the data to obtain Results; then analyze and process the processing results and issue new instructions through the control room; transmit the instructions to the instruction processor through the corresponding transmission lines and intermediary transmission devices; the instruction processor processes the instruction...
