As a professional provider of IoT data collection solutions, daq-iot, the data acquisition and IoT editor, will introduce the following content here and sincerely welcome everyone to discuss and communicate.

Identify the main program as CDialRecService.exe

1.2 Supports multiple types of digital instrument recognition.

1.3 Supports two modes: manual box selection and automatic instrument area recognition+box selection. Manual selection does not require training and has fast recognition speed, but it has poor tolerance for instrument movement and must ensure that the relative position between the camera and the instrument remains unchanged. Automatic instrument area recognition+box selection, requires collecting sample images for annotation training, supports small movements of the instrument, and has a slow recognition speed.

1.4 It is necessary to install the VS runtime environment.

1.5 Supports local directory/FTP/HTTP/CGIThe commonly used method to obtain images is CGI.

1.6 CGI mode can automatically connect the camera to capture images and store them in a specified directory.

1.7 After adjusting the recognition parameters in the configuration interface, it will take effect without restarting the software.

1.8 SupportModbus serviceAnd the client publishes data.

1.9 Support RMQ/AMQ/MQTTPublish data.

1.10 SupportMySQL databaseRecord.

1.11 Provide local recognition result query and scheduled export function

2. Instructions for use

2.1 Software Installation

Green software does not require installation, simply copy it to any location and double-click on the main program to run it.

2.2 Software Description

1. Software Catalog

2. Software startup

The software startup interface is shown in the figure above, and you can switch to the application software parameter page for parameter settings

Automatic restart: When manually exiting the software, it will automatically restart

Operation mode: After configuration is complete, it can be modified to service mode. Configuration mode (if the software is being configured, the background recognition thread will not run)

Retention time: The retention time of the image, beyond which it will be deleted (and database records will be deleted at the same time). Restart time: The software can be set to restart at what time

Data Cleaning: Report the identification result to the main switch for handling exceptions

Pop up alarm: When an abnormality is detected, the software will pop up a reminder

3. Add identification instruments

Switch to the data source configuration interface and follow the arrow direction process to operate

First enter the data source name ->click

Add data source ->Select data source (local) ->Select local file path (can be done directly)

Fill in the input box) ->click the save parameter button to save the parameters.

4. Add recognition template

Switch to the recognition template configuration interface, configure the recognition template as shown in the following figure, enter the dial name ->click

Add instruments

->Click the error parameter button to save the parameters ->click the area recognition button to select an image in the pop-up dialog box ->the software will automatically jump to the recognition area parameter interface. After configuring the recognition area, click the recognition test button (the recognition results will be displayed on the interface)

5. Identify configuration

1) Select region recognition image

2) . The image is shown in the following figure. Please turn on the area selection switch first (the left side is the area to be recognized by the instrument, and the right side is the specific number area within the area)

3). Frame recognition area (left click to select a single point, the software will automatically connect a line. When the fourth point is selected, the selection can be closed with the right click of the single mouse. If there is an error in the middle, you can click the previous step to go back to a point, or click the clear selection button to re frame the area). After clicking the save selection button, the software will automatically cut out the area (note that default preprocessing parameters will be used (at this time, you can switch to the preprocessing parameter interface to adjust and re recognize).

4). After clicking on the save area on the left, the selected area will be displayed on the right. If it is not scaled proportionally, you can click the refresh button or click the area recognition button to re recognize it.

5) Follow the arrows to operate sequentially. Note that the selected data should include as many complete numerical regions as possible, otherwise it may not be recognized accurately. The template will take effect after configuration is completed.
