[0048] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.

[0049] The embodiments of the present application are described below with reference to the accompanying drawings. Figures 1-4 The part tracking and positioning method, the central control system, the PLC system and the storage medium according to the embodiments of the present application are described below.

[0050] Figure 1is a flow chart of a part tracking positioning method according to an embodiment of the present application. As shown in Figure 1 A part tracking positioning method for a central control system, the method comprising the following steps:

[0051] Step S11: receiving a signal of successful placement of the part when the part is placed on the conveying belt.

[0052] Specifically, when the part is placed on the conveying belt, the central control system receives a signal of successful placement of the part, and starts the tracking positioning process of the part placed on the conveying belt.

[0053] In a specific embodiment, when the robot picks up the part from the steel plate and places the part on the conveying belt, a signal of successful placement of the part is reported to the central control system, and after the central control system receives the signal, it is indicated that the part has been successfully placed on the conveying belt, and at this time, the tracking positioning process of the part placed on the conveying belt is started.

[0054] Step S21: sending the number of the part to the PLC system.

[0055] Specifically, the number of the part is unique identification information for distinguishing the part, and the central control system and the PLC system track and position all parts placed on the conveying belt according to the number of the part, so as to track all parts on the conveying belt in the whole process. When tracking and positioning the part, the PLC system will record the position information of all parts on the conveying belt in real time according to the number information of the part.

[0056] Step S31: querying all tracking data of the parts stored in the PLC system every predetermined time.

[0057] Specifically, the central control system queries the tracking data of the parts stored in the PLC system every predetermined time, for example, once every second, so as to find out whether the part appears correctly at the corresponding station in time, and if the part does not appear correctly at the corresponding station, an abnormal alarm information will be sent.

[0058] Step S41: determining the tracking state of all parts according to the tracking data of the part.

[0059] Specifically, the central control system can determine whether all the parts on the conveying belt are correctly present on the corresponding stations according to the tracking data of all the parts queried from the PLC system, so as to determine the tracking state of all the parts on the conveying belt. For example, the conveying belt includes a plurality of stations, when a certain part is about to arrive at a station, for example, station No. 1, the central control system obtains the relevant information of the part, for example, position information, from the PLC system, and compares the position information with the pre-stored position information of the part in the central control system. If the comparison result is consistent, it is considered that the tracking state of the part is normal, and the equipment at the station can be adjusted to a reasonable state in advance to improve the working efficiency of the processing equipment at the station. Otherwise, the tracking state of the part is abnormal, and an alarm information is sent, so as to track the parts on the conveying belt in real time.

[0060] In an embodiment of the present application, the tracking data includes: the number, length, thickness, and position information of the part.

[0061] Specifically, the central control system can compare the tracking data of all the parts queried from the PLC system, for example, the number, length, thickness, and position information of the part, with the pre-stored list of the number, length, thickness, and position information of all the parts, to realize real-time tracking of the parts on the conveying belt.

[0062] In an embodiment of the present application, before the part is placed on the conveying belt, it further includes: generating the number information of the corresponding part according to the nesting drawing.

[0063] In a specific embodiment, when the part starts to be sorted, the central control system generates a globally unique number of all the parts by analyzing the nesting drawing data, and stores it in a persistent database, which is used to determine the tracking state of all the parts corresponding to the number of the part after querying the tracking data of all the parts from the PLC system.

[0064] In an embodiment of the present application, determining the tracking state of all the parts according to the tracking data of the part includes: obtaining the length and thickness information of the part corresponding to the position information; comparing the length and thickness information with the tracking data; if the comparison result is consistent, the tracking state of the part is normal, otherwise, the tracking state of the part is abnormal.

[0065] Specifically, when a certain part is about to arrive at a station, for example, station No. 2, the central control system obtains the length and thickness information of the part corresponding to station No. 2, compares the length and thickness information with the length and thickness information queried from the PLC system, and if the comparison result is consistent, the tracking state of the part is normal, otherwise, the tracking state of the part is abnormal.

[0066] In specific embodiments, when a certain part is about to arrive at a station, for example, the No. 2 station, the central control system collects the length and thickness information of the part at the No. 2 station through the 3D vision system, and then determines the number information of the part according to the length and thickness information, and compares the length and thickness information of the part corresponding to the number information queried from the PLC system. If the comparison result is consistent, the tracking state of the part is normal, otherwise, the tracking state of the part is abnormal.

[0067] According to the part tracking positioning method, the real-time position information of the part is obtained through the PLC system, and the length and thickness information of the part obtained is compared with the length and thickness information of the part queried from the PLC system corresponding to the position information, so that all the parts on the conveying belt are tracked in the whole process, which has the advantage of high real-time and can improve the working efficiency of the machining equipment at the station.

[0071] Step S22: real-time obtaining position information of the part corresponding to the number information.

[0072] Specifically, the PLC system obtains the position information of the part corresponding to the number information in real time according to the number information of all parts. For example, the PLC system can calculate the position information of the part on the conveying belt in real time through the encoder connected thereto. The calculation of the position information of the part through the encoder is prior art, which is not described here.

[0073] Step S23: storing the number information and the position information of the part corresponding to the number information into the tracking data queue, so that the central control system determines the tracking state of all parts according to the tracking data of the part.

[0074] Specifically, the tracking data queue is used to store all part tracking data on the conveying belt, such as the number and real-time position information, the PLC system updates the position information of the part to the tracking data queue in real time, and the central control system can poll the PLC system to obtain the positions of all parts in the tracking data queue to determine the tracking state of the part corresponding to the position information.

[0077] In an embodiment of the present application, the tracking positioning method of the part further comprises: when it is determined that the tracking states of all parts during the entire conveying process are normal, clearing the data in the tracking data queue.

[0078] Specifically, when all parts finally pass through the conveying belt, it is considered that the tracking states of all parts are normal, and the part transfer task is completed, then the data in the tracking data queue is cleared, and the next part transfer task is entered.

[0079] In a specific embodiment, for example, the part transfer task includes passing through a sanding machine, a code spraying machine, and a dark box on the conveying belt, when the tracking states of all parts during the entire conveying process are normal, it is considered that the part passes through the sanding machine, the code spraying machine, and the dark box normally, that is, the part transfer task is completed, then the PLC system clears the data in the tracking data queue, and the next part transfer task is entered.
