When the PLM (Product Lifecycle Management ) system releases the latest version into the BOM (Bill of materials), it synchronizes to the MES (Manufacturing Execution System ). Through the cloud server of the designed remote part firmware automatic upgrading device, automatic collaborative interaction with the MES system is established, when the cloud server recognizes that a new version change exists in the MES system, version capturing is automatically carried out, the latest software version is automatically carried out, and information generation and storage are carried out in a version model tree according to a unique identification number coding rule. Meanwhile, the cloud server presets an interface, and performs interface reservation with other systems needing interaction, so that high expandability and high availability of the system are maintained.
Step S2: and placing parts at the end of the brushing equipment. At the end of the brushing equipment, a part placement clamp is designed. After the parts are placed, the sensor at the brushing equipment end automatically performs signal recognition to capture the label identification number of the parts. And automatically identifying the versions of the parts at the brushing equipment end, and establishing communication interaction between the brushing equipment end and the cloud server after the parts are placed in the clamp. The parts automatically detect the current part software version through the communication unit at the device end and upload the current part software version to the cloud server. When different versions exist in batches of parts, the parts are automatically recorded and stored on the cloud server.
The sensor is a position sensor, and when a part is placed in the sensor, the position of the part is automatically identified, so that a signal is transmitted to the cloud end through the networking equipment by means of position identification, and the cloud end can identify that the part is placed in the sensor. Whereas existing brushstations manually secure the parts in a fixed position.
And the brushing equipment end and the cloud server are used for transmitting brushing signals. After the parts of the brushing equipment end are placed, stable interactive communication with the cloud server is established through a TCP/IP protocol. The cloud reporting of equipment information, version information and the like in the interaction process of signal communication execution, the information transmission of software versions, the transmission of result feedback signals, the transmission of communication contents such as reports of logs and upgrading logs and the like. And an information interaction mechanism between the part end and the refreshing equipment based on a communication protocol is established, so that information induction and refreshing action response of the cloud server to the refreshing station are realized, and refreshing is completed.

The hardware version is used for carrying out tag identification on the uniqueness of the parts so as to ensure the consistency of the writing and the reading of the parts. And performing software version management on the basis of the hardware version. In the software version management model tree, each item is composed of a plurality of software configuration items by taking an active item of each upgrade of a part as a root node. Each software version iteration records the change parameters and change reasons of the software, and establishes a software version tracing mechanism. And after the cloud server identifies the software version of the refreshing equipment, automatically performing upgrading target version matching.
The cloud server has the interactive function with the MES system, communication with the refreshing station, software version management of the product, success and failure management of upgrading activities, self-adaptive version upgrading and software system management on different parts. The software version management of the cloud server comprises the steps of automatically acquiring the latest version of the part to be updated from the MES system, quickly identifying the software version of the current part after communication with the refreshing station, and updating according to the latest version in the MES. The cloud server establishes software system management paths of different software versions, establishes a software version management model tree, automatically increases the version of the model tree when the MES system interactive end captures the new version, adaptively upgrades the software version uploaded by the brushwork station end interactive end, and completes automatic upgrade. The cloud server establishes a management mechanism for success and failure of the refreshing, transmits the refreshing result to a refreshing station end display page, and simultaneously mainly establishes a record and model library for the refreshing failure, performs log grabbing and failure root cause analysis of the software refreshing failure, continuously improves the refreshing success rate of parts and improves the production yield.
And the cloud terminal automatically brushes the brushing equipment terminal. After the cloud server obtains the upgrading request, the corresponding software package in the cloud server is called through identifying the label of the testing result of the upgrading package, and the parts of the refreshing equipment are adaptively refreshed if the testing result is successful. If no test result record exists or the test result does not pass, highlighting and early warning display is performed. And whether the upgrade package is tested and the result is identified and judged, so that double insurance is provided for version upgrade, and the wrong installation of the upgrade package is prevented.
And (5) monitoring upgrading process data. In the process of part brushing, the process of upgrading activity is monitored, and meanwhile, the process of upgrading activity is displayed. The monitoring object parameter data mainly comprises the data of the refreshing process of the parts, the abnormal data of the parts in the upgrading process, the upgrading time of the parts, the abnormality of the network and the like.
And (5) analyzing reasons of upgrade failure. In the cloud server, an upgrade failure cause analysis function is provided. Aiming at the abnormal factors of upgrading failure in the upgrading process, based on log analysis of the upgrading process, upgrading failure cause analysis under the multi-dimension conditions of software version matching errors, software communication anomalies, software function parameter mismatch and the like is carried out.
And the parts under the multi-space scene are cooperatively and automatically upgraded. The automatic upgrading device for the large-scale remote part firmware can be deployed in different space areas to conduct upgrading activities according to the requirements of use scenes. When new functions are released after the parts are offline, the parts can be stored in multiple warehouses and multiple spaces. Part of the parts are in a supplier warehouse, part of the parts are in a host factory warehouse, part of the parts are in a third party warehouse, and part of the parts are in a production line. The proposed refreshing terminal equipment with the terminal networking communication function is deployed in each space region, parts in storage can be upgraded in batches, and the cloud server can carry out establishment of an upgrading strategy and triggering of upgrading tasks according to refreshing equipment ends in different regions, so that large-scale part software refreshing is completed.
