Description

Technical Field

[0001] The present invention relates to the technical field of instrument reading, and in particular to a pointer-type instrument reading device and method. Background Art

[0002] In power grid operations, pointer meters, as a traditional and widely used monitoring tool, bear the important responsibility of recording equipment operating parameters. However, with the continuous expansion of the scale of the power grid and the improvement of the level of intelligence, the manual reading of pointer meter data has gradually revealed its limitations. This method is not only inefficient and prone to errors, but also difficult to obtain data in a timely and accurate manner when facing power grid facilities in harsh environments and remote areas, thereby increasing equipment failures and operational risks.

[0003] In the prior art, the instrument panel image is captured by a camera device, and then a series of pre-defined templates are used, each template corresponding to a different scale or pointer position on the instrument. Through the image matching algorithm, the real-time captured instrument image is compared with the template in the template library to find the best matching template, thereby determining the current position of the pointer. The advantages of this solution are simple algorithm, small amount of calculation, and suitable for scenes with fixed background and fixed scale. The disadvantages are poor adaptability to light changes, instrument dirtiness, etc., and different template libraries need to be prepared for different instruments. Summary of the invention

[0004] The present invention aims to at least solve the technical problems of hysteresis, poor environmental adaptability and high cost in the prior art of manually reading data.

[0005] To this end, an object of the present invention is to provide a pointer instrument reading device, comprising an isolation cover connected above the instrument panel, a light source arranged inside the isolation cover, a camera arranged inside the isolation cover, and an image analysis unit electrically connected to the camera.

[0006] Furthermore, the isolation cover is made of ABS material, which can effectively isolate the interference of external dust and oil, ensure the consistency of the detection environment, and improve the reading accuracy in harsh environments.

[0007] Furthermore, it also includes an alarm, which is connected to the image analysis unit. When the instrument panel reading exceeds the alarm threshold, the alarm sounds an alarm under the control of the image analysis unit.

[0008] Furthermore, it also includes a storage unit, which is connected to the image analysis unit, and the storage unit stores the meter reading information analyzed by the image analysis unit.

[0009] Furthermore, it also includes a wireless communication module, which is electrically connected to the image analysis unit. The wireless communication module sends the instrument reading information analyzed by the image analysis unit to a remote monitoring server for real-time monitoring by relevant persons in charge.

[0010] Furthermore, the isolation cover is a conical structure, which can prevent dust from contaminating the instrument panel.

[0011] Furthermore, the light source is an LED light strip.

[0012] Furthermore, the light source is a ring light.

[0013] The present invention provides a pointer instrument reading method, which is implemented using any of the pointer instrument reading devices described above, and comprises the following steps:

[0014] Step S1: Connecting the isolation cover above the instrument panel;

[0015] Step S2: turning on the light source disposed inside the isolation cover;

[0016] Step S3: using the camera to collect the instrument panel pointer image;

[0017] Step S4: the image analysis unit analyzes the instrument panel pointer image to determine the pointer reading.

[0018] Furthermore, the image analysis unit analyzes the instrument panel pointer image to determine the pointer reading, including:

[0019] The image analysis unit identifies the outline of the pointer;

[0020] Calculate the pointer angle;

[0021] Convert the pointer angle to a reading.

[0022] The present invention provides a pointer-type instrument reading device and method, which has the following beneficial effects:

[0023] The present invention uses a sealed isolation cover made of ABS material and sets up a stable light source, which effectively isolates interference from external dust and oil pollution, ensures the consistency of the detection environment, improves reading accuracy in harsh environments, and improves environmental adaptability.

[0024] The present invention has a complete data processing and alarm mechanism, which can realize the functions of storing and backing up the meter reading information data, forwarding it to the monitoring server, and automatically processing the alarm. When the meter reading is abnormal, it can alarm in time, send the alarm information to the remote monitoring server in time, and push it to the corresponding person in charge for problem handling, ensuring the timeliness and accuracy of data processing. The present invention can read the meter data in real time and quickly respond to emergency situations such as equipment failure, and has very strong immediacy.

[0025] The present invention adopts low-cost components and an easy-to-deploy design to reduce overall costs, while simplifying installation and maintenance processes, facilitating widespread application in power grids.

[0026] The device of the present invention has good scalability and compatibility, can adapt to instruments of different models and specifications, and is easy to integrate with other power grid monitoring systems to achieve more comprehensive monitoring functions. The present invention solves practical problems in power grid monitoring and improves the safety and reliability of power grid operation. BRIEF DESCRIPTION OF THE DRAWINGS
