In addition, real-time updating of manufacturing service information provides references for service matching, reconfiguration, etc., and prevents service anomalies. In order to track the dynamic information of the manufacturing service in real time, real-time data acquisition is required for the on-site processing equipment. If all the collected data are transmitted to the industrial cloud platform for processing, the network transmission bandwidth is high in pressure, and the data safety cannot be guaranteed. And the industrial cloud platform has a certain time delay from analyzing and processing data to making decisions, so that the real-time response requirement is difficult to ensure. Many data will lose effect soon after collection and analysis and therefore there is no need to store on the industrial cloud platform to consume the storage capacity of the industrial cloud platform. The existing method is that the field data are all sent to the industrial cloud platform for processing after being collected, and the industrial cloud platform only informs service demander of the current task to be executed of the dynamic information of the service, so that the requirement of resource sharing cannot be met.

And the service price generation module is used for responding to the first selection information, calling the real-time evaluation information and the state information of the manufacturing service corresponding to the service provider terminal according to the first selection information, and generating price information of the manufacturing service to form real-time dynamic information. And the manufacturing service selection module is used for updating the service requirement business state according to the second selection information.
The price information is obtained by the following formula:
wherein w is e And w w The influence proportion of the waiting time of the service evaluation information and the newly added service demander on the service price is respectively represented; p (P) base Representing a base price for the service;the evaluation grade of the corresponding service; t is t md Indicating a maximum time that the service requester is willing to wait; t is t w Representing the waiting time of the newly joined service demander.

if the current state is the state of just completing the task, the evaluation information and the state information are updated at the same time, wherein the state information is the sum of the processing time and the maintenance time of the task scheduled by the service.
As shown in fig. 2 and 3, the information update flow of the real-time update system for the micro annular part manufacturing service specifically includes:
s101, a service provider logs in an industrial cloud platform to release services. The basic information and the functional information of the service are expressed by using an extensible markup language (eXtensible Markup Language, XML) description model. The evaluation information, state information and price information of the manufacturing service belong to the dynamic information of the service, and are supplemented and updated in real time along with the execution task of the service. Since this patent focuses on real-time updates of manufacturing services, its static information is not discussed in detail.
S102, a service demander logs in an industrial cloud platform and issues manufacturing tasks and technical requirements of the industrial cloud platform.
And S103, matching proper services by the industrial cloud platform according to the basic information and the functional information of the services and pushing the services to service requesters.
And S104, the service demander performs first selection on the service pushed by the industrial cloud platform.
And S105, the industrial cloud platform sends the service selection result of the service demander to the edge computing equipment of each service, and requests the edge computing equipment to acquire the evaluation information and the state information of each service according to the real-time data analysis of the processing site.
And S106, after the edge computing equipment receives the request of the industrial cloud platform, firstly detecting whether the service is working.
And S107, if the service is in an idle stage, the edge computing equipment informs the industrial cloud platform that the service dynamic information is up to date and does not need to be updated.
And S108, if the edge computing equipment detects that the service is working, continuing to detect whether the service completes the current task.
And S109, if the edge computing device detects that the service is executing the current task, the edge computing device updates the state information of the service. The status information is quantified by the latency of the newly joined service demander. At this time, the edge computing device updates the completion time of the service executing the current task and the completion time of the task scheduled by the service, so as to determine the waiting time of the newly added service demander. The rating information is still the rating information when the last task of the service is completed, and no update occurs. The status information of the service can be represented by formula (1).
t w =t c +t o +t r (1)
Wherein t is w Representing the waiting time of a newly joined service demander, t c 、t o 、t r The current task completion time of the service, the processing time of the scheduled task and the maintenance time of the service are respectively represented.
And S110, if the edge computing equipment detects that the service just completes the current task, the evaluation information and the state information of the service need to be updated. The evaluation of the service was classified into five classes: the excellent, good, medium, and grade, and bad, respectively, correspond to intervals (0.8,1), (0.6,0.8), (0.4,0.6), (0.2, 0.4), (0,0.2).
And S111, the edge computing equipment sends the updated evaluation information and state information to the industrial cloud platform.
And S112, the industrial cloud platform dynamically determines the price of the service according to the evaluation information and the state information of the service. The dynamic change of the price takes into account the fairness Guan Qiedu of the service demander and can adjust the service demand to avoid task blocking. The price of the service may be determined according to equation (2).
Wherein w is e And w w The influence proportion of the waiting time of the service evaluation information and the newly added service demander on the service price is respectively represented; p (P) be Representing a base price for the service;corresponding to the evaluation grade of the service, the value range is (0, 1)];t md Indicating a maximum time that the service requester is willing to wait beyond which the service requester may create an discontent emotion; t is t w Representing the waiting time of the newly joined service demander determined by step S109 or S110.
And S113, the industrial cloud platform sends the updated service evaluation information, state information and price information to the newly added service demander.
And S114, the newly added service demander performs second selection on the service in the first selected service set according to the service dynamic information sent by the industrial cloud platform.
S115, after the newly added service demander makes a selection for the service, the new service demander enters a stage of executing the task or waiting for the task to be executed.
And S116, if the task of the newly added service demander is executed, the edge computing equipment updates the state information of the service according to the data acquired on site. The status information covers the time that the task has been performed, the time that the consumer being serviced needs to wait.
The edge computing device detects whether the state information of the service is normal or not S117. If the fault occurs, the edge computing equipment analyzes the fault and reports the fault to the industrial cloud platform.
S118, the industrial cloud platform sends a notification to related objects: a served consumer, a consumer waiting for the service, a service provider performing the task, and a subsequent affiliated provider providing the service. The notification sent at this time is an emergency notification, which takes precedence over a general notification.
And S119, the industrial cloud platform and a service provider for executing the tasks take corresponding measures. The service provider performing the task performs a timely state assessment of the service. If the service cannot be recovered to be normal in a short period of time, the industrial cloud platform reconfigures and schedules the service, so that the loss is reduced as much as possible.
And S120, if the edge computing equipment detects that the state information of the service is normal, the industrial cloud platform informs the state information of the service to a served requester, a service requester waiting for the service, a service provider executing the task and a service provider joining the execution task. The industrial cloud platform informs the corresponding demander of the waiting time and the price of the demander which has reserved the service, so that the demander waiting for the service predicts the result of the service, and timely adjusts the reserved service. The waiting time and the service price of the demander waiting for the service can be calculated by equations (1) and (2), respectively. Complex tasks require multiple service providers to cooperatively accomplish. The allied suppliers know the service progress in time and adjust the service scheme. The time for the affiliated provider to wait for the task to be executed includes the time for the pre-collaboration provider to execute the task and the time for the task to be transmitted, which can be determined according to formula (3). At this time, the notification sent by the industrial cloud platform is a general notification, and by selectively notifying the relevant object, invalid update notification is avoided.
t w ′=t co +t t (3)
Wherein t is w ' represents the latency of the federation provider, t co 、t t Respectively, the time of task execution and the time of task transmission of the pre-collaboration provider.
And S121, after the task order is completed, the industrial cloud platform evaluates the service according to the task execution condition and determines the price to be paid by the service demander according to the formula (2). The service demander pays according to the price information.
And S122, the demand merchant waiting for the service receives the general notification and the emergency notification about the waiting service sent by the industrial cloud platform. The general notification includes information already discussed in step S120. Emergency notification refers to the service exception.
S123, the demander waiting for the service predicts the execution result of the task according to the notification sent by the industrial cloud platform, and negotiates and adjusts the selected service.
Example 2
Some manufacturers need to process miniature annular parts, and the processing steps of the parts include: laser engraving, polishing and quality inspection. The industrial cloud platform automatically matches { A, B, C } of the services capable of completing laser engraving { D, E } of the services capable of completing light splitting { F } of the services capable of completing quality inspection { F } according to the basic information and the functional information of each manufacturing service. The information of each service is assumed to be shown in table 1.
TABLE 1 information of services
Note that: service C is a service newly released by a service provider, and no evaluation information exists at present. The service needs to be maintained once after executing a task once.
The industrial cloud platform first requests the edge computing device of service A, B, C to detect the dynamic information of service A, B, C.
1) The edge computing device detects that the service A does not currently execute the task, and the edge computing device informs the industrial cloud platform that the dynamic information of the service A does not need to be updated.
2) The edge computing device detects that service B is executing a certain task, and there are 2 more hours to complete the current task, and there are 2 tasks currently waiting for service B to execute. According to formula (1), if the vendor selects service B, the waiting time is:
t w =2+0.5×3+3×2=9.5h
the evaluation information of service B is not changed at this time. Assume that the manufacturer is willing to wait for a maximum time t during the laser engraving phase md For 5h, the rating and latency are equally important to the manufacturer, i.e., w e =w w =0.5 h. The industrial cloud platform calculates the price of the service B at this time by using the formula (2) according to the state information (vendor waiting time) and the evaluation information (evaluation level) updated by the edge computing device:
P=0.5×500×0.9+0.5×500×9.5/5=700
3) The edge computing device detects that service C has just completed a certain task, and service C currently has 1 task to perform. If the newly added service demander selects service C, the waiting time is required according to formula (1):
t w =2+0.3×2=2.6h
the industrial cloud platform determines that the evaluation grade of the service C is 0.6 according to the product percent of pass and the like, and can calculate the price of the service C at the moment as follows:
P=0.5×600×0.6+0.5×600=480
table 2 updated information for each service of laser engraving
The updated information of the laser engraved service A, B, C is shown in table 2.
And the manufacturer selects the service A to finish the laser engraving according to the updated information of each service of the laser engraving sent by the industrial cloud platform. The process of selecting the polishing and quality inspection service is the same as the process of selecting the laser engraving service, and will not be described in detail. The manufacturer finally selects service A, D, F to finish laser engraving, polishing and finishing of the part, respectively. Assume that the transit times of the work in process between services A, D, F are t respectively AD =2h,t DF =2.5h。
And when the part is laser engraved, the edge computing equipment updates the state information of the service A in real time. Service A needs 4 hours to finish laser engraving, if the service A is finished for 2 hours, manufacturers need to wait for the laser engraving to finish for 2 hours. If a new service consumer joins the industrial cloud platform and selects the service A, waiting time and paid service price are as follows:
from Table 1, it is clear that the times for service D and service F to enter the part for finishing and finishing are 6h and 8h, respectively. Calculating waiting time of service D and service F entering the polishing and quality inspection according to a formula (3):
the industrial cloud platform will inform the manufacturer that the waiting time for laser engraving is 2 hours, the waiting time for newly added service demander is 2.2 hours, the price to be paid is 360, the waiting time for service D to enter the profile is 4 hours, and the waiting time for service F to enter the quality inspection is 20.5 hours.
After the laser engraving is completed, the manufacturer determines the price to be paid to service a according to formula (2):
P=0.5×400×0.8+0.5×400=360
after the manufacturer finishes the payment of the service A, the manufacturer sequentially enters a polishing and quality inspection stage, and the service updating process is similar to the laser engraving process and is not described in detail.
