Among them, the surface of the above-mentioned belt conveyor platform can adopt anti-static materials to reduce the influence of static electricity on the test results of the above-mentioned target test product, and the above-mentioned belt conveyor platform can also adopt high-strength materials to reduce wear.
[0026] Among them, the protection component is connected to the transmission component and is used to perform a power-off operation on the transmission component when it is determined that the load of the transmission component is greater than a preset load threshold.
[0027] Exemplarily, the current value of the above-mentioned drive motor and / or the torque value corresponding to the above-mentioned drive motor can be monitored in real time to determine the real-time load of the transmission component. When it is determined that the above-mentioned real-time load is greater than the preset load threshold, a power-off operation is performed on the above-mentioned drive motor to switch the transmission component from the operating state to the shutdown state.

[0050] In some feasible embodiments, the above-mentioned test module further includes: a diagnosis unit for determining the corresponding fault type according to the signal feature difference, where the fault type includes: analog quantity fault, input fault, output fault, acquisition fault, and / or communication fault.
[0051] Exemplarily, in the case of determining that the difference in voltage signal characteristics is greater than the corresponding preset difference, and / or, in the case of determining that the difference in current signal characteristics is greater than the corresponding preset difference, the corresponding fault type is determined as an analog quantity fault.
[0052] Exemplarily, in the case of determining that the difference in the input signal characteristics is greater than the corresponding preset difference, the corresponding fault type is determined as an input fault.

The fault types include: analog quantity fault, input fault, output fault, acquisition fault, and / or communication fault, which is beneficial to improving the fault diagnosis and troubleshooting efficiency of the target test product, thereby further improving the test accuracy and test efficiency of the target test product, and further improving the product quality of the target test product.
[0057] In some feasible embodiments, the above system further includes: a calibration module, configured to perform a target calibration operation on the target test product in the case of determining that the signal characteristic difference is greater than the corresponding preset difference.
[0058] Exemplarily, in the case of determining that the difference in voltage signal characteristics is greater than the corresponding preset difference, the difference in current signal characteristics is greater than the corresponding preset difference, and / or, the difference in DC quantity characteristics is greater than the corresponding preset difference, then based on the probe, the corresponding target calibration operation can be performed on the voltage, current, and / or DC quantity according to the preset calibration parameters, so that the voltage signal characteristic difference is less than or equal to the corresponding preset difference, the DC characteristic difference is less than or equal to the corresponding preset difference, and / or the DC quantity characteristic difference is less than or equal to the corresponding preset difference.

[0064] Specifically, in the case where it is determined that the increment of the operation power, the operation temperature, and / or the noise is greater than the corresponding preset increment threshold, and / or in the case where it is determined that the production efficiency is lower than the preset production efficiency threshold, the gasket, the screw knob, the coordinate measuring machine, and / or the offset parameter can be adjusted to make the above increment less than or equal to the above corresponding preset increment threshold.
