[0002] The present invention relates to an error warning module, and more particularly to an error warning module installed in an electronic device. [Background technology]

[0003] Generally, when an electronic device transmits power or a signal, the transmitted power or signal inevitably contains a transmission error. For example, a user may set a power supply to provide a current of 10 amperes. However, a person skilled in the art may understand that although the power supply can output 10 amperes, due to various non-ideal factors, it may have a transmission error of 9 to 11 amperes (slightly greater or less than 10 amperes). When an electronic device is used for a certain period of time, a transmission error within a tolerable range may initially be acceptable, but due to non-ideal factors, the transmission error may become even larger. Therefore, it is necessary to calibrate the electronic device to ensure that it can transmit power or a signal correctly. Summary of the Invention [Problem to be solved by the invention]

[0004] In fact, it takes a lot of time and effort for engineers to calibrate multiple electronic devices, which will undoubtedly increase the burden on engineers. Therefore, a new calibration mechanism for electronic devices is needed in the industry to reduce the labor burden. [Means for solving the problem]

[0005] The present invention provides an error warning module that can be installed in an electronic device, and when the transmission error of the electronic device exceeds a threshold, the error warning module can automatically send a warning signal, thereby saving users the trouble of checking the electronic devices one by one.

[0006] The present invention discloses an error warning module installed in an electronic device, the error warning module including a detection unit and a processing unit. The detection unit detects a current or voltage transmitted by the electronic device to generate a current detection signal or a voltage detection signal. The processing unit electrically connected to the detection unit determines whether the detected current value indicated by the current detection signal exceeds a current setting range or whether the detected voltage value indicated by the voltage detection signal exceeds a voltage setting range. If the detected current value exceeds the current setting range or the detected voltage value exceeds the voltage setting range, the processing unit generates a warning signal.

[0007] In some embodiments, if the electronic device is an electronic load device, the detection unit can detect a current or voltage drawn by the electronic load device to generate a current detection signal or a voltage detection signal. The current setting range is related to a preset load current value of the electronic load device, and if the current detection value deviates from the preset load current value by a first threshold, the processing unit can determine that the current detection value exceeds the current setting range, and then a warning signal is generated. The voltage setting range is related to a preset load voltage value of the electronic load device, and if the voltage detection value deviates from the preset load voltage value by a second threshold, the processing unit can determine that the voltage detection value exceeds the voltage setting range, and then a warning signal is generated.

[0008] In some embodiments, when the electronic device is a power supply, the detection unit can detect a current or a voltage output by the power supply to generate a current detection signal or a voltage detection signal. Moreover, the current setting range is related to a preset supply current value of the power supply, and when the current detection value deviates from the preset supply current value by a third threshold, the processing unit can determine that the current detection value exceeds the current setting range, and then a warning signal is generated. Also, the voltage setting range is related to a preset supply voltage value of the power supply, and when the voltage detection value deviates from the preset supply voltage value by a fourth threshold, the processing unit can determine that the voltage detection value exceeds the voltage setting range, and then a warning signal is generated.

[0009] In some embodiments, the temperature at the location of the detection unit can be lower than the average temperature of the electronic device. The detection unit can further repeatedly detect the current or voltage transmitted by the electronic device during the detection time and repeatedly generate multiple current or voltage detection signals during the detection time. Furthermore, the processing unit can determine whether the current detection value indicated by each current detection signal exceeds a current setting range, and if the number of times the current detection value exceeds the current setting range reaches a fifth threshold within the detection time, the processing unit can generate a warning signal. Furthermore, the processing unit can determine whether the voltage detection value indicated by each voltage detection signal exceeds a voltage setting range, and if the number of times the voltage detection value exceeds the voltage setting range reaches a sixth threshold within the detection time, the processing unit can generate a warning signal.

[0010] Based on the above, the error warning module provided by the present invention can be installed in an electronic device to automatically detect whether there is a transmission error in the current or voltage output or received by the electronic device. If the transmission error of the current or voltage output or received by the electronic device exceeds a preset threshold, the error warning module can automatically send a warning signal, thereby saving users the trouble of checking the electronic devices one by one. [Brief explanation of the drawings]

[0011] [Figure 1] FIG. 2 is a schematic diagram of an error warning module according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] The features, objects and functions of the present invention will be further disclosed below. However, these are only a few of the possible embodiments of the present invention, and the scope of the present invention is not limited thereto. That is, equivalent changes and modifications made in accordance with the claims of the present invention remain the subject of the present invention. Without departing from the spirit and scope of the present invention, these changes and modifications should be considered as further possibilities of the present invention.

[0013] Please refer to FIG. 1, which is a schematic diagram of an error warning module according to an embodiment of the present invention. As shown in FIG. 1, an electronic device 1 may include a power module 10 and an error warning module 12, and the power module 10 can be used to perform the main functions of the electronic device 1. For example, if the electronic device 1 is an electronic load device, the external device 2 to which the electronic device 1 is connected may be a power supply. Here, the power module 10 may be a module that consumes power and receives current or voltage from the external device 2, and the power module 10 may be a load for the external device 2. On the other hand, if the electronic device 1 is a power supply, the external device 2 to which the electronic device 1 is connected may be considered a kind of load. Here, the power module 10 may be a module that supplies power to the external device 2 and outputs current, and the power module 10 may be a power supply for the external device 2.

[0014] In addition, the error warning module 12 may include a detection unit 120 and a processing unit 122. The detection unit 120 may be connected in series between the power module 10 and the external device 2, and the processing unit 122 may be electrically connected to the power module 10 and the detection unit 120. In fact, the detection unit 120 may be used to detect a current or voltage transmitted between the electronic device 1 and the external device 2. This embodiment does not limit the direction of the current. For example, the electronic device 1 may output a current or voltage to the external device 2, or the electronic device 1 may receive a current or voltage from the external device 2. In addition, the detection unit 120 is disposed or installed within the electronic device 1. The installation location of the detection unit 120 should be a location with excellent heat dissipation so that the detection unit 120 is not affected by temperature and thus does not cause detection errors. For example, the installation location of the detection unit 120 is far away from other components within the electronic device 1 that are prone to generating heat, so that the temperature at the installation location of the detection unit 120 is lower than the average temperature of the electronic device 1.

[0015] Taking the aforementioned electronic device 1, which may be an electronic load device, as an example, the power module 10 is used to consume power provided by the external device 2, so the detection unit 120 detects a current or a voltage from the external device 2 and generates a current detection signal or a voltage detection signal. As an example, if the detection unit 120 is used to detect a current, a user can set a current (e.g., a preset load current value) to be drawn by the power module 10 through a control interface (not shown in FIG. 1 ). Of course, this embodiment does not limit how the power module 10 is configured. A setting command from the user through the control interface can be received by the processing unit 122, and the processing unit 122 can then configure the power module 10. For example, a user can set the power module 10 to draw a current of 10 amperes (i.e., the preset load current value is 10 amperes), and then when the power module 10 starts up, the detection unit 120 detects the current detection value actually drawn by the power module 10.

[0016] Here, because the electronic device 1 does not necessarily start transmitting current immediately after powering on, the detection unit 120 may initially be in a standby mode or a non-centralized detection mode (with a longer sampling interval). Additionally, the current detection value actually detected by the detection unit 120 may be recorded in the current detection signal. Assuming that the detection unit 120 actually detects only 9 amperes, the value of 9 amperes may be the current detection value. The processing unit 122 then receives the current detection signal from the detection unit 120 and determines that the current detection value is 9 amperes. Because the processing unit 122 knows the preset load current value (10 amperes) of the power module 10 at this point, the processing unit 122 can determine whether the current detection value exceeds the current setting range. In an example, assuming that the current setting range is known to be 9.5 amperes to 10.5 amperes, the processing unit 122 can determine that the current detection value (9 amperes) is below the lower limit of the current setting range. Therefore, the processing unit 122 generates a warning signal to indicate that the electronic device 1 is currently under an abnormal load condition. In other words, if the current detection value deviates from the preset load current value by a first threshold value (0.5 amperes in this example), the processing unit 122 can determine that the current detection value exceeds the current setting range. In this embodiment, the current setting range is not particularly limited, and the current setting range can be regulated by the specifications of the electronic device 1 or set by a user.

[0017] Of course, for more accurate detection, the processing unit 122 can repeatedly receive multiple current detection signals within the detection time. For example, assuming that the detection unit 120 can perform detection 10 times within 1 millisecond, the processing unit 122 can receive the 10 current detection signals. The processing unit 122 can then determine how many of the current detection values ​​corresponding to the 10 current detection signals exceed the current setting range. A user can set how many abnormal current detection values ​​the processing unit 122 should detect before generating a warning signal, which means that the user can determine the warning threshold (fifth threshold) themselves. In one example, the user can set the warning threshold to 3. That is, if three current detection values ​​corresponding to the current detection signals exceed the current setting range within the detection time, the processing unit 122 can determine that the electronic device 1 is currently under an abnormal load condition, and therefore, the processing unit 122 generates a warning signal.

[0018] This embodiment does not limit the detection unit 120 to detecting current; the detection unit 120 can also be used to detect voltage. For example, a user can set the power module 10 to draw 10 volts (i.e., the preset load voltage value is 10 volts) by using a control interface (not shown in FIG. 1 ), and the voltage detection value actually detected by the detection unit 120 can be recorded in the voltage detection signal. Assuming that the detection unit 120 actually detects 9 volts, the value of 9 volts can be considered as the voltage detection value. In addition, the processing unit 122 can receive the voltage detection signal from the detection unit 120 and know that the voltage detection value is 9 volts. Furthermore, it is assumed that the processing unit 122 knows that the preset load voltage value of the power module 10 is 10 volts. Therefore, the processing unit 122 can determine whether the voltage detection value exceeds the voltage setting range. As in the previous example, assuming the voltage setting range is known to be 9.5 volts to 10.5 volts, processing unit 122 can determine that 9 volts is too low and below the lower limit of the voltage setting range, and therefore processing unit 122 generates a warning signal to warn that an abnormal load is currently being applied to electronic device 1. In other words, if the voltage detection value deviates from the preset load voltage value by a second threshold (0.5 volts in this example), processing unit 122 can determine that the voltage detection value exceeds the voltage setting range.

[0019] Similarly, the processing unit 122 can repeatedly receive multiple voltage detection signals within the detection time. For example, assuming that the detection unit 120 can perform detection 10 times within 1 millisecond, the processing unit 122 can receive 10 voltage detection signals, determine how many of the voltage detection values ​​corresponding to the voltage detection signals exceed the voltage setting range, and also determine a warning threshold (sixth threshold) by the user.

[0020] On the other hand, taking the aforementioned electronic device 1 as another example, the power module 10 is used to supply the required power to the external device 2. Therefore, in this example, the detection unit 120 detects the current output from the power module 10 to the external device 2 and then generates a current detection signal. In practice, a user can set a preset supply current value, which is the current output by the power module 10, through a control interface (not shown). Similarly, a user can set the power module 10 to output a current of 10 amperes, and then, when the power module 10 starts working, the detection unit 120 detects the actual current value (which is the current detection value) output by the power module 10. Here, the current detection value actually detected by the detection unit 120 can be recorded in the current detection signal. For example, assuming that the detection unit 120 actually detects only 9 amperes, the value of 9 amperes can be the current detection value.

[0021] Similar to the previous example, assuming the current setting range is known to be 9.5 amps to 10.5 amps, processing unit 122 can determine that 9 amps is too low and below the lower limit of the current setting range, and therefore processing unit 122 generates a warning signal to indicate that electronic device 1 currently has an abnormal output current. In other words, if the current detection value deviates from the preset supply current value by a third threshold (0.5 amps in this example), processing unit 122 can determine that the current detection value exceeds the current setting range.

[0022] Take the detection unit 120 for detecting voltage as an example. The detection unit 120 can detect the voltage output from the power module 10 to the external device 2, so that the detection unit 120 can generate a voltage detection signal. Similarly, a user can set a preset supply voltage value to be output by the power module 10 through a control interface (not shown). In practice, a user can set the power module 10 to output a voltage of 10 volts. Then, when the power module 10 starts working, the detection unit 120 detects the voltage value actually output by the power module 10. Here, the voltage detection value actually detected by the detection unit 120 can be recorded in the voltage detection signal. Assuming that the detection unit 120 actually detects 9 volts, the value of 9 volts can be the voltage detection value. The voltage setting range is known to be 9.5 volts to 10.5 volts, and the processing unit 122 can determine that 9 volts is too low and falls below the lower limit of the voltage setting range. The processing unit 122 generates a warning signal to warn that the electronic device 1 currently has an abnormal output voltage. In other words, if the detected voltage value deviates from the preset supply voltage value by the fourth threshold (0.5 volts in this example), the processing unit 122 can determine that the detected voltage value exceeds the voltage setting range.

[0023] In summary, the error warning module provided by the present invention can be installed in an electronic device to automatically detect whether there is a transmission error in the current or voltage output or received by the electronic device. If the transmission error of the current or voltage output or received by the electronic device exceeds a preset threshold, the error warning module can automatically send a warning signal, thereby saving users the trouble of checking the electronic devices one by one.
