[0047] According to one aspect of the present invention, Figure 1 As shown, a control system of an automatic and precise feeding device is provided. First, the feeding module cooperates with the driving module to debug and convey the items stored in the storage module. At the same time, the detection module has a built-in camera processing device and cooperates with the CNN (convolutional neural network) algorithm to photograph the items to be conveyed and process the images. Then, the key features in the items are identified and compared with the standard features. If there is a difference, it means that the items are unqualified, and the unqualified items are rejected by the automatic rejection module.

[0048] Then, the actual voltage and current information data on the driving module of the number of items detected by the detection module, the number of items transported by the feeding module, and the number of items to be transported in the storage device are collected respectively through the material inspection quantity collection module, the feeding quantity collection module, the storage quantity collection module, the voltage collection module and the current collection module, and the data is stored through the data storage unit, and then the data is transmitted to the data processing unit through the data transmission unit.

If:

[0051]

[0052] It means that the items to be transported stored in the storage device are sufficient and there is no need to add raw materials to the storage device.

If:

[0057]

[0058] This means that the safety index of the control system is within a reasonable range and the control system of the automatic precision feeding device can operate normally. When , it means that the safety index of the control system operation is unreasonable, the control system of the automatic precision feeding device cannot operate stably, and triggers an abnormal alarm. It is necessary to cut off the power supply or stop feeding through the power control module to prevent accidents. Among them, δ is the safety index of the control system operation, μ is the remaining index of the items to be transported in the storage device, and V s is the feeding speed of the feeding module, V c is the detection speed of the detection module, For the calculation of the speed index, U j is the voltage value on the driver module at the jth second, I j is the current value on the driver module at the jth second, For the calculation of actual electric power, U e is the rated voltage value on the drive module, I e is the rated current value of the drive module, is the calculation of the power index between the actual electric power and the rated electric power, time is the operating time of the drive module, t is the operating time of the control system debugging of the automatic precision feeding device, δ e The threshold parameter of the preset safety index is used to calculate the safety index of the control system operation through comprehensive analysis of the residual index, speed index and power index.
