The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts.

In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
An embodiment of the present invention provides a testing method, and fig. 1 is a flowchart of the testing method provided in the embodiment of the present invention, where the embodiment is applicable to testing a temperature monitoring function of a power module of a flexible dc valve control device, and the method may be executed by a testing device, where the testing device may be implemented by software and/or hardware, and the method includes:
s1001, adjusting a test temperature threshold of the flexible direct current valve control device according to the current temperature of the power module.
Wherein the adjusted test temperature threshold is lower than the current temperature of the power module; the current temperature of the power module refers to the current operating temperature of the power module.
The flexible direct-current valve control device comprises a power module temperature monitoring function, namely a function of monitoring the temperature of the power module, and a function of controlling the power module to be opened (operated) and closed (not operated), and when the temperature or the temperature difference value of the power module is higher than preset values (temperature threshold value and temperature change threshold value), the flexible direct-current valve control device can control the power module to be closed (not operated); the electrical component packaging module for preventing reverse connection and/or overcurrent of the power module package block may be, for example, a half-bridge module shown in fig. 2, where T1 and T2 are two IGBTs (semiconductor switching devices), D1 and D2 are diodes, C is a capacitor (stored energy), R is a discharge resistor, and S is a mechanical bypass switch.
S1002, adjusting a test temperature change threshold of the flexible direct current valve control device according to the current temperature difference value of the power module at two adjacent sampling time points.
The adjusted test temperature change threshold is lower than the current temperature difference value of the power module at two adjacent sampling time points; the two adjacent sampling time points refer to any two adjacent detection time points in the temperature sensor of the flexible direct-current valve control device.
S1003, receiving alarm information of the flexible direct current valve control device, and testing whether the temperature monitoring function of the power module of the flexible direct current valve control device is normal or not according to the alarm information.
For example, first, the temperature threshold of the flexible dc valve control device is adjusted to be below the current temperature of the power module, that is, the test temperature threshold, and the temperature change threshold of the flexible dc valve control device is adjusted to be below the current temperature difference of the power module at two adjacent sampling time points, that is, the test temperature change threshold, at this time, the current temperature of the power module exceeds the test temperature threshold, and the current temperature difference of the power module at two adjacent sampling time points exceeds the test temperature change threshold; if the flexible direct-current valve control device can monitor that the current temperature of the power module exceeds a test temperature threshold value and the current temperature difference value of the power module at two adjacent sampling time points exceeds a test temperature change threshold value, and outputs corresponding alarm information, the temperature monitoring function of the power module of the flexible direct-current valve control device is normal; if the flexible direct-current valve control device does not output corresponding alarm information, it is indicated that the flexible direct-current valve control device does not monitor the current temperature of the power module and the current temperature difference value is abnormal, or the flexible direct-current valve control device detects the current temperature of the power module and the current temperature difference value is abnormal, but fails to output corresponding alarm information, and the power module temperature monitoring function of the flexible direct-current valve control device is judged to be abnormal.
According to the embodiment of the invention, the test temperature threshold value of the flexible direct-current valve control device is adjusted to be lower than the current temperature of the power module, and the test temperature change threshold value of the flexible direct-current valve control device is adjusted to be lower than the current temperature difference value of the power module at two adjacent sampling time points, so that the current temperature and the current temperature difference value of the power module exceed and/or reach the test temperature threshold value and the test temperature change threshold value, and whether the temperature monitoring function of the power module of the flexible direct-current valve control device is normal can be judged through the alarm information of the flexible direct-current valve control device.
Illustratively, the power module temperature monitoring function of the flexible direct current valve control device comprises a power module temperature overhigh monitoring function, a power module temperature continuous overhigh monitoring function and a power module temperature change abnormity monitoring function, and the alarm information of the flexible direct current valve control device comprises power module temperature overhigh alarm information, power module temperature continuous overhigh alarm information and power module temperature change abnormity alarm information. The power module over-temperature monitoring function is that when the flexible direct-current valve control device detects that the temperature of the power module exceeds and/or reaches a certain threshold value, the power module is controlled to be closed (stop working) and power module over-temperature alarm information is output; the power module temperature continuous overhigh monitoring function means that when the flexible direct current valve control device detects that the temperature of the power module continuously exceeds and/or reaches a certain threshold value within a certain time period, the power module is controlled to be closed (stop working) and power module temperature continuous overhigh alarm information is output; the power module temperature change abnormity monitoring function is that when the flexible direct current valve control device detects that the temperature difference value of the power module at two adjacent sampling time points exceeds and/or reaches a certain temperature change threshold value, the power module is controlled to be closed (stop working) and abnormal temperature change alarm information of the power module is output.
It can be understood that the flexible direct-current valve control device comprises an industrial personal computer, the industrial personal computer comprises a display unit, and when the flexible direct-current valve control device outputs alarm information, the display unit of the industrial personal computer can display corresponding alarm information, so that a worker can be reminded to take measures in time.
Optionally, fig. 3 is a flowchart of another testing method provided in the embodiment of the present invention, as shown in fig. 3, the method includes:
s2001, adjusting a first test temperature threshold value of the flexible direct current valve control device according to the current temperature of the power module.
Wherein the adjusted first test temperature threshold is lower than the current temperature of the power module. The first test temperature threshold is a test threshold used by the test device to test whether the function of the flexible direct-current valve control device for monitoring whether the temperature of the power module exceeds a certain temperature threshold is normal.
S2002, receiving first alarm information of the flexible direct current valve control device, and testing whether the power module overhigh temperature monitoring function of the flexible direct current valve control device is normal or not according to the first alarm information.
Wherein, first alarm information is power module high temperature alarm information.
Illustratively, the temperature threshold of the flexible direct current valve control device is adjusted to a first test temperature threshold, and the current temperature of the power module exceeds the first test temperature threshold; if the flexible direct-current valve control device can monitor that the current temperature of the power module exceeds a first test temperature threshold value and outputs corresponding first alarm information, the power module overhigh temperature monitoring function of the flexible direct-current valve control device is normal; if the flexible direct-current valve control device does not output corresponding first alarm information, it is indicated that the flexible direct-current valve control device does not monitor that the current temperature of the power module is too high, or the flexible direct-current valve control device detects that the current temperature of the power module is too high, but fails to output corresponding first alarm information, and the function of monitoring that the temperature of the power module of the flexible direct-current valve control device is too high is judged to be abnormal.
For example, if the flexible dc valve control device can monitor that the current temperature of the power module is "too high", and can output first alarm information, a display interface of an industrial personal computer of the flexible dc valve control device can display a message of "power module over-temperature alarm", so that when the flexible dc valve control device normally works, an alarm can be sent to a worker in time to remind the worker to take measures.
Optionally, fig. 4 is a flowchart of another testing method provided in the embodiment of the present invention, as shown in fig. 4, the method includes:
s3001, adjusting a second test temperature threshold of the flexible direct current valve control device according to the current temperature of the power module.
The adjusted second test temperature threshold value is continuously lower than the current temperature of the power module within the preset time; the second test temperature threshold is less than the first test temperature threshold; the second test temperature threshold is a test threshold used by the test device to test whether the function of the flexible dc valve assembly for monitoring whether the temperature of the power module continuously exceeds a certain temperature threshold is normal, that is, whether the temperature of the power module is continuously higher. For example, when the operating temperature of the power module reaches a high temperature in a short time, the power module is very easy to damage, so a flexible direct-current valve control device is needed to monitor whether the current temperature of the power module is too high; when the operating temperature of the power module reaches a higher temperature within a period of time, the power module is easy to damage or destroy, so that a flexible direct-current valve control device is needed to monitor whether the current temperature of the power module is continuously higher; the higher temperature is higher than the higher temperature, so that when the temperature monitoring function of the power module of the flexible direct-current valve control device is tested to be normal or not, in order to meet the actual working condition, the first test temperature threshold is larger than the first test temperature threshold.
S3002, receiving second alarm information of the flexible direct current valve control device, and testing whether the power module temperature continuous high monitoring function of the flexible direct current valve control device is normal or not according to the second alarm information.
The second alarm information is alarm information that the temperature of the power module is continuously higher.
Illustratively, the temperature threshold of the flexible direct current valve control device is adjusted to a second test temperature threshold, and the current temperature of the power module in the preset time continuously exceeds the first test temperature threshold; if the flexible direct-current valve control device can monitor that the current temperature of the power module in the preset time continuously exceeds the first test temperature threshold value and output corresponding second alarm information, the continuous high temperature monitoring function of the power module of the flexible direct-current valve control device is normal; if the flexible direct-current valve control device does not output corresponding second alarm information, it is indicated that the flexible direct-current valve control device does not monitor that the current temperature of the power module is continuously higher within the preset time, or the flexible direct-current valve control device detects that the current temperature of the power module is continuously higher within the preset time, but fails to output corresponding second alarm information, and all the conditions are that the function of monitoring the temperature of the power module of the flexible direct-current valve control device is abnormal when the temperature of the power module is continuously higher.
For example, if the flexible dc valve control device can monitor that the current temperature of the power module is continuously "higher" within a preset time, and can output second alarm information, the display interface of the industrial personal computer of the flexible dc valve control device can display a message of "power module continuously higher warning", so that when the flexible dc valve control device normally works, an alarm can be timely sent to a worker to remind the worker to take measures.
Optionally, fig. 5 is a flowchart of another testing method provided in the embodiment of the present invention, and as shown in fig. 5, the method includes:
s4001, adjusting a test temperature change threshold of the flexible direct current valve control device according to the current temperature difference value of the power module at two adjacent sampling time points.
The adjusted test temperature change threshold is lower than the current temperature difference value of the power module at two adjacent sampling time points; the two adjacent sampling time points refer to any two adjacent detection time points in the temperature sensor of the flexible direct-current valve control device.
S4002, receiving third alarm information of the flexible direct current valve control device, and testing whether the power module temperature difference value overhigh monitoring function of the flexible direct current valve control device is normal or not according to the third alarm information.
And the third alarm information is alarm information about abnormal temperature change of the power module.
Illustratively, the temperature change threshold of the flexible direct current valve control device is adjusted to a test temperature change threshold, and at this time, the current temperature difference value of the power module at two adjacent sampling time points exceeds the test temperature change threshold; if the flexible direct-current valve control device can monitor that the current temperature difference value of the power module at two adjacent sampling time points exceeds the test temperature change threshold value and output corresponding third alarm information, the abnormal monitoring function of the temperature change of the power module of the flexible direct-current valve control device is normal; if the flexible direct-current valve control device does not output corresponding third alarm information, it is indicated that the flexible direct-current valve control device does not monitor that the current temperature changes of the power module at two adjacent sampling time points are abnormal, or the flexible direct-current valve control device detects that the current temperature changes of the power module at two adjacent sampling time points are abnormal, but fails to output corresponding third alarm information, and the power module temperature change abnormity monitoring function of the flexible direct-current valve control device is judged to be abnormal.
For example, if the flexible dc valve control device can monitor that the current temperature changes of the power module at two adjacent sampling time points are "abnormal", and can output third alarm information, the display interface of the industrial personal computer of the flexible dc valve control device can display a message of "power module change abnormality warning", so that when the flexible dc valve control device works normally, an alarm can be sent to a worker in time to remind the worker to take measures.
Optionally, fig. 6 is a flowchart of another testing method provided in the embodiment of the present invention, and as shown in fig. 6, the method includes:
s5001, adjusting a test temperature threshold value of the flexible direct current valve control device according to the current temperature of the power module.

S5003, receiving alarm information of the flexible direct current valve control device, and testing whether the temperature monitoring function of the power module of the flexible direct current valve control device is normal or not according to the alarm information.
S5004, if the temperature monitoring function of the power module of the flexible direct-current valve control device is normal, adjusting the test temperature threshold again to enable the test temperature threshold to be higher than the current temperature, so as to obtain a temperature threshold when the flexible direct-current valve control device normally works, and adjusting the test temperature change threshold again to enable the test temperature change threshold to be higher than the current temperature difference, so as to obtain a temperature change threshold when the flexible direct-current valve control device normally works.
For example, after testing whether the temperature monitoring function of the power module of the flexible direct-current valve control device is normal, if the test result is normal, adjusting the temperature threshold of the flexible direct-current valve control device from the test temperature threshold to a temperature threshold during normal operation, where the temperature threshold during normal operation is higher than the current temperature of the power module and higher than the operating temperature of the power module during normal operation; and the temperature change threshold value of the flexible direct current valve control device is adjusted from the test temperature change threshold value to the temperature change threshold value during normal work when the test result is normal, wherein the temperature threshold value during normal work is higher than the current temperature difference value of the power module at two adjacent sampling time points and higher than the running temperature change of the power module at two adjacent sampling time points during normal work. Optionally, if the temperature monitoring function of the power module of the flexible dc valve control device is abnormal, the test temperature threshold and the test temperature change threshold are not adjusted until the temperature monitoring function of the power module of the flexible dc valve control device is normal.
Illustratively, the temperature threshold includes a first temperature threshold and a second temperature threshold, the first temperature threshold being higher than the second temperature threshold. When the flexible direct-current valve control device and the power module both work normally, if the flexible direct-current valve control device detects that the operating temperature of the power module exceeds and/or reaches a first temperature threshold value, the flexible direct-current valve control device displays a message of 'power module over-temperature alarm' on a display interface of an industrial personal computer of the flexible direct-current valve control device to send an alarm to a worker, and the worker is reminded to take measures; if the flexible direct-current valve control device detects that the operating temperature of the power module continuously exceeds and/or reaches a second temperature threshold value and the duration time exceeds the preset time, the flexible direct-current valve control device sends a warning to a worker by displaying a message of 'power module temperature continuously higher warning' on an industrial personal computer display interface, and the worker is reminded to pay attention or even replace during system power failure maintenance; if the flexible direct-current valve control device detects that the temperature change of the power module exceeds and/or reaches a temperature change threshold value in two adjacent sampling time points, the flexible direct-current valve control device sends a warning to a worker by displaying a message of 'abnormal power module temperature change warning' on an industrial personal computer display interface, and the worker is reminded to pay attention or even replace during system power failure maintenance.

And S6004, displaying a test result to prompt a worker whether the temperature monitoring function of the power module of the flexible direct current valve control device is normal.
For example, the test result can be displayed by a self-contained indicator light, a display screen and the like on the test device.
