********Glossary
The software collects data from a device that has a communication interface and uses a specific communication protocol to communicate. The device can be a detection instrument, a small meter, a sensor , or even a separate PLC .
Factors are the properties of a device, including its measured value, state, control unit, etc. For example, for an air conditioner , The following attributes can be called a factor:
The physical connection method between the data acquisition system and the equipment and the basic communication protocol. For example, it can be using a serial communication line, using RS 232 or RS 485 interface; or use network cable RJ 45 interface, use TCP / IP Communication protocol. Support multiple devices
Share a link.
The communication protocol analysis program between the data acquisition system and the device. On the one hand, it analyzes the data collected from the device into the data format used by the acquisition system, and on the other hand, it analyzes the commands sent by the acquisition system to the device into the data format understood by the device. Mode.

The certification process is:
1. Copy the machine code and provide it to the supplier.
2. Obtain certification documents from suppliers.
3. Upload the certification documents.
It should be noted that one authentication file can only authenticate one computer.
********Collection Configuration
********Driver Management
The driver management page is shown in the figure below:
You can download the driver of the corresponding device from the official website, upload it to the system, and then use it for the device.
********Link Configuration
The link configuration page is shown below:
The currently supported links and the contents that need to be configured are shown in the following table:
| Link Type | Contents to be configured | Remark |
|---|---|---|
| TCP Client | server IP ,port | |
| Serial Port | Serial port number, baud rate, check bit, data bit, Stop bits | |
| TCP Server | server IP ,port | |
| UDP | remote IP , port, local IP ,port | |
| OPC - UA Client | server URL , Username, Password | Only anonymous and username login methods are supported If the user is empty, it is anonymous. |
| No transmission | none | For virtual devices |
****Equipment Configuration
The device configuration page is shown below:
Devices using different drivers will have different configuration information. However, some information needs to be configured for all devices, such as
| Configuration Content | illustrate |
|---|---|
| Using the driver | The driver used by the device. You can select the driver added in the driver management page. |
| Use Link | The link used by the device. The link added in the link configuration page is optional. |
| Send waiting time | The frequency at which the system sends commands to the device when collecting data. The unit is milliseconds. |
| Receiving waiting time | After the system sends a command to the device, the expected time for the device to respond normally. The unit is milliseconds. |
| Stop collecting errors number | In a transmit - receive loop, if an error occurs, the error count is incremented. 1 When the number of errors exceeds this value, Wait for a while before starting the collection. |
| Stop collection time | The time to stop collecting data after the number of errors exceeds the limit, in milliseconds. |
The following table shows:
The device contains factors, and the factor configuration page is shown below:
Similarly, for devices using different drivers, the information that needs to be configured for the factors is also different. The two common attributes are as follows: Down:
********expression
If the value you want to display / upload is different from the original value collected from the device, you can use an expression to match it. For example, the unit of the collected data is mg , but the unit of uploaded data is g , then you need to divide the original value by 1000 The expression supports basic operations, including four arithmetic operations, exponential operations, trigonometric functions, etc. For operation support, please refer to Section A1 .
A reference to itself in an expression is { self } , references to other factors are { device name . Factor Name } , For example :
| occasion | Existence Factor | Expression Writing |
|---|---|---|
| The original unit is mg , need to upload unit g | Electronic scale.Weight | { self }/1000 |
| If there is a Celsius measurement, you need to upload Fahrenheit at the same time | Thermometer . Celsius | { Thermometer.Celsius } * 1.8 +32 |
********Numeric conversion
Some values may not be displayed in numerical form, especially the status of the device. 0 stands for standby, 1 stands for measuring, and 2 stands for measurement completed. After collecting data, the user may want to see the standby Machine, measuring, measurement completed, instead of 0 , 1 , 2 . At this time, you can configure the value conversion. The format of the value conversion The formula is:
Original value 1=> Display value 1| Original value 2=> Display value 2| … | Original value n=> Display value n
For example, for the above example, the value conversion configuration is: ” 0=> Standby |1 => Measuring |2=> Measurement completed ”.
********Database Management
The database management page is shown below:
】
From this page, you can:
-
Select the database type, Currently available SQLite , MySQL and SQL Server .
-
The storage time can be a few minutes interval, or a specified time point.
-
Clean the data and delete the factor columns that no longer exist.
-
Clear data. Generally, clear all data after the device configuration is completed.
********Software Usage
********Start and stop collection
The data acquisition system can start collecting data after the computer is turned on, and no additional operations are required for normal daily use. In some cases, such as equipment maintenance or configuration modification, you can temporarily stop the collection. Click the Pause / Launch the Run button to do this:
It should also be noted that after each configuration change , you need to restart the collection for it to take effect.
********View device collection status
If you need to view the current collection status, you can open the device monitoring page, as shown below:
From this page, you can:
