[0059] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0060] Current output devices that need to provide stable and adjustable current output are common in industrial, laboratory and daily life scenarios, such as programmable power supplies, current sources, DC power supplies, AC power supplies, and current regulators. These devices play an important role in different application scenarios.

[0061] In the related art, hardware devices such as potentiometers are usually used to assist in calibrating the output current.

[0062] However, the current current calibration method has the problems of low calibration efficiency and poor accuracy.

[0063] Based on the above problems, embodiments of the present application provide a current calibration method, apparatus, computer device, storage medium and computer program product.

[0064] In one embodiment, Figure 1 As shown, a current calibration method is provided. This embodiment takes the method applied to a terminal as an example. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0065] Step 102: In response to detecting an abnormal output current, entering an output calibration mode of the target device.

[0066] Step 104: stimulating the target device based on a preset first input signal, comparing the output value of the target device with a preset benchmark reference value, and calibrating the output benchmark value of the target device based on the comparison result.

[0067] The output reference value may be the current value of the target device in the minimum working state, that is, the KCOB value.

[0068] Exemplarily, the terminal may stimulate the target device based on a preset first input signal, compare the output value of the target device with a preset benchmark reference value, and calibrate the output benchmark value of the target device based on the comparison result.

[0069] Step 106: After the output reference value is calibrated, the target device is stimulated based on a preset second input signal, the output value of the target device is compared with a preset current reference value, and the output gain value of the target device is calibrated based on the comparison result.

[0070] The output gain value may be the slope of the current value change function of the target device in the gain working state, that is, the KCO value.

[0071] Step 108: In response to the calibration of the output reference value and the output gain value being completed, closing the output calibration mode of the target device.

[0072] Exemplarily, the calibrated current may be Irel, Irel = (((Ipre-Imin)*kco)>>8)+kcob.

[0073] In the above-mentioned current calibration method, reasonable deduction is performed in combination with the technical features in the embodiment, which can achieve the following beneficial effects of solving the technical problems raised in the background technology:

[0074] A current calibration method includes: in response to detecting an abnormal output current, entering an output calibration mode of a target device; stimulating the target device based on a preset first input signal, comparing the output value of the target device with a preset reference value, and calibrating the output reference value of the target device based on the comparison result; after the output reference value is calibrated, stimulating the target device based on a preset second input signal, comparing the output value of the target device with a preset current reference value, and calibrating the output gain value of the target device based on the comparison result; in response to the completion of the calibration of the output reference value and the output gain value, closing the output calibration mode of the target device. In implementation, the output control of the current is mainly controlled by an input signal, and the target device has a base value of the current output. On the basis of the base value, the current magnitude of the final output is controlled by the input signal and the current gain. Therefore, when determining that the current output is abnormal, the output reference value is first calibrated, and on the basis of the completion of the calibration of the output reference value, the current output value is increased by the input signal, thereby realizing the calibration of the output gain value, and finally completing the calibration process of the current output. Compared with the related art, it is helpful to save the hardware, materials and equipment required for current calibration, and realize the calibration automatically through program control, which is helpful to improve the efficiency of current calibration.

[0075] In one embodiment, the Figure 2 As shown, step 104 includes:

[0076] Step 202: Obtain the minimum output current value of the target device;

[0077] Step 204: calibrate the output reference value according to the comparison result between the minimum output current value and the reference value.

[0078] In this embodiment, the output reference value is calibrated according to the minimum output current value of the target device in the minimum working state. Since the minimum working state can represent the output value of the target device in the absence of gain, that is, the reference value, the output reference value can be calibrated, which helps to improve the efficiency and accuracy of current calibration.

[0079] In one embodiment, the Figure 3 As shown, step 106 includes:

[0080] Step 302: Obtain the maximum output current value of the target device;

[0081] Step 304: calibrate the output gain value according to the comparison result between the maximum output current value and the current reference value.

[0082] In this embodiment, the output gain value is calibrated according to the maximum output current value of the target device in the maximum working state. Since the maximum working state can represent the output value of the target device with gain, that is, the reference value plus the gain part, the output gain value can be calibrated, which helps to improve the efficiency and accuracy of current calibration.

[0083] In one embodiment, the Figure 4 As shown, after step 102, the following further includes:

[0084] Step 402: In response to the target device entering the calibration mode;

[0085] Step 404: Stop the target device from outputting current signals to the connected associated device.

[0086] In the present embodiment, in the processing flow of current calibration, since there is a process of stimulating the target device to test it by outputting current, in the present embodiment, by cutting off the target device's output current to the associated device in the calibration mode, it is possible to avoid the output current exceeding the safety interval of the associated device, thereby helping to improve the safety of current calibration.

[0087] In one embodiment, the Figure 5 As shown, before step 102, the following steps are also included:

[0088] Step 502: calling a preset system output reference value and a system output gain value to initialize the target device;

[0089] Step 504: Obtain the current output value of the target device during the initialization process. If the current output value is different from the instruction value of the initialization process, it is determined that there is an output current abnormality.

[0090] In this embodiment, in the control process of the target device, determining whether the target device has an output abnormality through initialization processing helps to improve the efficiency of current output control of the target device and improve the response speed of current output abnormality.

[0091] In one embodiment, the Figure 6 As shown, step 502 includes:

[0092] Step 602: In response to the adjustment instruction for the target device, adjusting the system output reference value and the system output gain value based on a preset micro-step value;

[0093] Step 604: Perform the initialization process of the target device based on the adjusted system output reference value and the system output gain value.

[0094] In this embodiment, the default system output reference value and system output gain value of the target device can be adjusted according to usage requirements, and can be fine-tuned according to specific micro-step values, which helps to improve the flexibility of using the target device and can also improve the accuracy of adjustment through tiny step values.

[0095] In a most specific embodiment, the specific current calibration process is as follows:

[0096] First, during the initialization process, call the default current calibration parameters: kcob, kco. After the initialization is completed, the output current is detected. If it meets the nameplate requirements, no calibration is required. If not, enter the calibration mode. After entering the calibration mode, first calibrate the small current Imin, that is, calibrate the value of kcob. If Imin is too small, increase the value of kcob. If Imin is too large, reduce the value of kcob. If it meets the requirements, go directly to the next step. After calibrating the small current Imin, calibrate the large current Imax, that is, calibrate the value of kco. If Imax is too small, increase the value of kco. If Imax is too large, reduce the value of kco. If it meets the requirements, go directly to the next step. After calibration, exit and retest to meet the nameplate requirements.

[0097] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
