Abstract

The present disclosure provides an Industrial Internet of Things and a control method of an Industrial Internet of Things for handling failure of an assembly line equipment. The Industrial Internet of Things include a user platform, a service platform, a management platform, a sensor network platform, and an object platform interacting in sequence. The service platform, the management platform, and the sensor network platform all adopt an independent arrangement. The object platform is configured as a plurality of manufacturing equipment arranged in sequence according to a process sequence on the assembly line, and each of the manufacturing equipment separately corresponds to the service platform, the management platform, and the sensor network platform.

First claim

What is claimed is:

1. An Industrial Internet of Things for handling failure of an assembly line equipment, comprising: a user platform, a service platform, a management platform, a sensor network platform, and an object platform interacting in sequence, wherein
the service platform, the management platform, and the sensor network platform all adopt an independent arrangement composed of a plurality of sub platforms with a same number, and the independent arrangement means that the service platform, the management platform, or the sensor network platform uses different sub-platforms for data storage, data processing, and/or data transmission for data of different object platforms;
the object platform is configured as a plurality of manufacturing equipment arranged in sequence according to a process sequence on the assembly line, the plurality of sub-platforms of different platforms form a one-to-one correspondence between upper and lower levels, and the sensor network platform, management platform, and service platform corresponding to each one-to-one correspondence all correspond to a same manufacturing equipment; when any of the manufacturing equipment fails, the manufacturing equipment uploads a failure code to sub-platforms of the sensor network platform;
sub-platforms of the management platform are configured to
receive a configuration file sent by the sub-platforms of the sensor network platform, pre-store a failure code table corresponding to the manufacturing equipment, the failure code table at least including the failure code, and a failure type and a self-repair instruction package corresponding to the failure code, and after receiving the configuration file, extract the failure code in the configuration file and match the failure code with the failure code table, retrieve the failure type and the self-repair instruction package corresponding to the failure code, and package the failure code, failure type, and the self-repair instruction package as the identification result; and issue a self-repair instruction to the sub-platforms of the sensor network platform based on an identified result, wherein the sub-platforms of the sensor network platform converts the self-repair instruction into a self-repair instruction file recognized by the manufacturing equipment and issues the self-repair instruction file to the manufacturing equipment, and the manufacturing equipment performs a self-repair based on the self-repair instruction file and feeds back a self-repair result to the sub-platforms of the management platform; and analyze the self-repair result, when the self-repair result is not repaired,
upload the identified result and the self-repair result to sub-platforms of the service platform, wherein the sub-platforms of the service platform synchronously send the identified result and the self-repair result to the user platform;

the user platform is configured to obtain the failure handling instruction based on the identified result and the self-repair result, and sequentially send the failure handling instruction to the sub-platforms of the sensor network platform through the sub-platforms of the service platform and the sub-platforms of the management platform in turn; and
the sub-platforms of the sensor network platform is configured to convert the failure code into the configuration file identifiable by the management platform, and send the configuration file to the sub-platforms of the management platform; and convert the failure handling instruction into a failure handling instruction file identifiable by the manufacturing equipment, and issue the failure handling instruction file to the manufacturing equipment, and the manufacturing equipment executes a failure handling based on the failure handling instruction file.

2. The Industrial Internet of Things for handling failure of the assembly line equipment according to claim 1 , wherein the self-repair instruction issued by the sub-platforms of the management platform at least include the self-repair instruction package, and after receiving the self-repair instruction file, the manufacturing equipment extracts the self-repair instruction operation program data in the self-repair instruction package to perform self-repair.

3. The Industrial Internet of Things for handling failure of the assembly line equipment according to claim 1 , wherein the failure code table also includes an estimated failure handling time corresponding to the failure code,
the sub-platforms of the management platform are further configured to:
package the estimated failure handling time, the failure code, the failure type, and the self-repair instruction package as the identification result and upload the identification result to the sub-platforms of the service platform, and
take a previous manufacturing equipment of failed manufacturing equipment as a target object, wherein the sub-platforms of the management platform corresponding to the target object obtain a temporary storage amount of products of the target object and a production time of a single product, and upload the temporary storage amount of products of the target object and the production time of the single product to the sub-platforms of the service platform corresponding to the target object;
the user platform is further configured to:
retrieve the temporary storage amount of products and the production time of the single product of the sub-platforms of the service platform corresponding to the target object;
extract the estimated failure handling time of the identification result, and calculate a total product production amount of the target object within the estimated failure handling time through the estimated failure handling time and the production time of the single product;
determine whether to activate a standby manufacturing equipment and use a determination result as a part of the failure handling instruction based on a difference between the total product production amount and the temporary storage amount of products; and
when the sub-platforms of the management platform of the failed manufacturing equipment receive the failure handling instruction and issue the failure handling instruction to the sub-platforms of the sensor network platform at the same time, determine whether to execute a step of enabling the standby manufacturing equipment based on the determination result.

4. The Industrial Internet of Things for handling failure of the assembly line equipment according to claim 3 , wherein to determine whether to execute a step of enabling the standby manufacturing equipment based on the determination result, the at least one processor is executed to operations including:
the standby manufacturing equipment and the failed manufacturing equipment sharing one sub-platform of same management platform and one sub-platform of the sensor network platform;
when the determination result is to enable the standby manufacturing equipment, the sub-platforms of the management platform generating an enabling command and sending the enabling command to the sub-platforms of the sensor network platform corresponding to the standby manufacturing equipment; and
after converting the enabling command, the sub-platforms of the sensor network platform corresponding to the standby manufacturing equipment sending it to the standby manufacturing equipment, and the standby manufacturing equipment starting to replace the failed manufacturing equipment to manufacture products based on the enabling command.

5. The Industrial Internet of Things for handling failure of the assembly line equipment according to claim 3 , wherein the failure code table further includes a production time of a single product corresponding to the failed manufacturing equipment;
the sub-platforms of the management platform are further configured to sum
