Figure 2 is a flowchart of the operation method of the data recording system shown in Figure 1 of an embodiment of the present invention.

FIG. 1 is a schematic diagram of a data recording system 100 according to an embodiment of the present invention. The data recording system 100 may include a host 110 and a data recorder 120A. The data recorder 120A includes a plurality of module card slots SA1 to SAN and a plurality of data channels CHA1 to CHAM, where N and M are positive integers.

In some embodiments, the data channels CHA1 to CHAM of the data logger 120A can be coupled to different points to be tested in the system under test TS, and the user can insert the module cards MC1 to MCN into the module card slot SA1 To the SAN, and set the data channel corresponding to each module card MC1 to MCN through the host 110 to capture and record the data corresponding to the point to be measured.

FIG. 2 is a flowchart of an operation method 200 of the data recording system 100 according to an embodiment of the present invention. The method 200 includes steps S210 to S290.

S210: The host 110 defines the module card MC1 to correspond to the data channel CHA1 of the data logger 120A and the module card slot SA1; S220: Insert the module card MC1 into the module card slot SA1; S230: Data logger 120A stores the first type data DA1 captured by the data channel CHA1 to the module card MC1; S240: the host 110 causes the data logger 120A to interrupt the capture of the first type data; S250: the host 110 defines the module card MC2 corresponds to the data channel CHA2 of the data logger 120A and the module card slot SA1; S260: shuts down the data logger 120A; S270: removes the module card MC1 from the module card slot SA1; S280: Insert the module card MC2 into the module card slot SA1; S290: restart the data logger 120A; because in the data recording system 100, each module card can have a specific number and can be used to store specific types of data Therefore, when the user wants to use the module card MC1 to record the data measured by a specific point to be measured in the system under test TS1, the host 110 will first define the module card MC1 and the data record in step S210 Correspondence between the data channel CHA1 of the device 120A and the module card slot SA1. In some embodiments, the user can control the host 110 through the user interface provided by the host 110, and then issue commands to the data logger 120A.

Then, in step S220, the user can insert the module card MC1 into the module card slot SA1, and activate the data logger 120A, and the data logger 120A can, in step S230, capture the data channel CHA1 The first type data DA1 is stored in the module card MC1.

In some embodiments, if the user wants to remove the module card MC1 to record other points to be tested For data data, in order to prevent the data logger 120A from being unable to access the new module card smoothly, and/or to prevent the data logger 120A from automatically restarting and causing data loss during the plugging and unplugging process of the module card, the user can In S240, the main control terminal 110 is used to make the data recorder 120A interrupt the retrieval of the first type of data.

In addition, before swapping the module card MC1 into a new module card MC2, the user needs to define the data channel corresponding to the module card MC2 through the host 110 in step S250. For example, the module card MC2 can record the data of another point to be tested in the system under test TS1 through another data channel CHA2 of the data logger 120A. Furthermore, the host 110 can also define the corresponding relationship between the module card MC2 and the module card slot SA1 to be inserted to ensure that the data logger 120A can smoothly transfer the data of the new point to be measured after restarting. The data is recorded in the module card MC2.

After completing the setting operation of step S250, the user can shut down the data logger 120A in step S260, and then remove the module card MC1 from the module card slot SA1 in steps S270 and S280, and remove the module Insert the card MC2 into the module card slot SA1. After confirming that the module card MC2 has been inserted into the module card slot SA1, the data logger 120A can be restarted in step S290. When the data logger 120A is restarted, the data logger 120A can store the second type data captured by the data channel CHA2 to the module card MC2.

In some embodiments, the data logger 120A continuously retrieves data. Therefore, in some embodiments, in order to prevent the data logger 120A from being unable to operate normally due to the inability to continuously obtain data during the interruption process, the host 110 When the data logger 120A interrupts to retrieve the first type of data, the corresponding redundant data can be generated to the data logger 120A, such as but not limited to N/A, to replace the first type of data. Similarly, when the data recorder 120A is shut down, the host 110 can also generate redundant data to replace the first type of data.

In addition, in some embodiments, the first type of data and the second type of data can be different types of data. For example, the first type of data can be temperature-related data, and the second type of data can be current-related data. . However, the present invention is not limited to this, in other aspects of the present invention In the embodiment, the first type of data and the second type of data can also be other types of data, and they can be the same or different types of data.

In this way, through the method 200, the module card can be replaced on the data logger 120A without affecting the operation of the data recording system 100, so that the testing process can be more flexible and the hardware cost can be reduced.

In addition, in some embodiments, the data recording system 100 may further include more data loggers. For example, in Figure 1, the data recording system 100 may further include a data logger 120B. The data logger 120B can be coupled to the control terminal 110, so the user can control the data logger 120B through the control terminal 110. The data logger 120B and the data logger 120A may have similar functions, and may include a plurality of module card slots SB1 to SBN and a plurality of data channels CHB1 to CHBM.

Since the data loggers 120A and 120B can operate independently, when the host 110 causes the data logger 120A to interrupt the retrieval of the first type of data, the data logger 120B can continue to retrieve data. Similarly, when the data logger 120A is turned off, the data logger 120B can also continuously retrieve data.

Furthermore, in Figure 1, the module card MC3 is also inserted into the module card slot SA2 of the data logger 120A. The module card MC3 can correspond to the data channel CHA3 of the data logger 120A. In other words, the data logger 120A can store the third type data captured by the data channel CHA3 to the module card MC3. In some embodiments, when the host 110 causes the data logger 120A to interrupt the retrieval of the first type of data, the data logger 120A also interrupts the retrieval of the third type of data, and to avoid data loss, the host 110 The third type of data captured by the third data channel CHA3 can also be temporarily stored in the internal memory.

In summary, the operation method of the data recording system provided by the embodiments of the present invention can interrupt data capture before inserting and removing the module card, and set up the new module card and data channel and module. After the corresponding relationship between the card slots, insert and remove. In this way, it can be ensured that after the module card is inserted and removed, the data logger can still access the newly inserted module card and continue to record the data of another point to be tested, making the test process more flexible and Can add data logger Use efficiency, and reduce hardware costs.

The foregoing descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention shall fall within the scope of the present invention.
