Technical Field

The invention provides an automatic synchronous station control method and system, and belongs to the technical field of station synchronous control of production lines.

Background

In conventional automated manufacturing lines in the manufacturing industry, products are typically produced in a line with spaces between stations and multiple products in the process. In this production mode, a visual inspection system or other inspection device is used for product inspection. Conventionally, once a certain camera or inspection device is found to be misplaced, the corresponding product is rejected immediately, which generally means that the camera and rejection device are located in adjacent stations. However, this approach may not only lead to a decrease in product quality and production efficiency, but also require a downtime for necessary parameter tuning, further affecting production efficiency. This approach is clearly unsuitable, especially for higher speed production lines.

In today's increasingly high precision and high efficiency production environment, ensuring time synchronization between devices is critical to maintaining the accuracy and stability of the production process. However, the time synchronization technology based on GPS and a network clock server (such as SYN2151 type NTP synchronization time server) widely used in the current automation production line has problems of high cost and easily affected by network delay. More importantly, NTP protocols lack sufficient security mechanisms and may face security threats such as denial of service attacks, clock poisoning, etc.

Thus, one skilled in the art of manufacturing is facing an urgent technical challenge: how to base on the clock synchronization technology, the problems of high cost, low synchronization accuracy and safety in the prior art are solved, and the accuracy and stability of the production process can be obviously improved, so that the production efficiency and the product quality are improved.

In one embodiment of the present invention, acquiring trigger time information of a product detection station of an automated production line and time information of product detection equipment of the product detection station during a commissioning process includes:

Specifically, in this embodiment, the detailed steps of acquiring trigger time information of a product detection station of an automated production line and time information of product detection equipment of the product detection station in a test run process include:

s101, initializing a product detection equipment trigger controller of a product detection station of an automatic production line by an upper computer corresponding to a clock synchronous controller

S102, initializing the product detection device trigger controllers, and acquiring initial time intervals between trigger actions of the product detection device trigger controllers of every two adjacent product detection stations and time differences of detection action execution between product detection devices corresponding to each product detection device trigger controller in the process of test operation.

Specifically, initializing the product detection device trigger controller, and acquiring an initial time interval between trigger actions of the product detection device trigger controllers of every two adjacent product detection stations and a time difference between detection action executions of the product detection devices corresponding to each product detection device trigger controller in a test running process, wherein the method comprises the following steps:

s1021, after initialization is completed, the upper computer controls a conveying device of the automatic production line to perform trial operation according to a set conveying speed;

S1022, controlling the product detection equipment trigger controllers corresponding to each product detection station on the automatic production line by the upper computer in the test operation process to generate detection trigger signals, acquiring time intervals between trigger actions of the product detection equipment trigger controllers of every two adjacent product detection stations, and taking the time intervals as initial time intervals;

S1023, the upper computer retrieves the rated time interval of the product detection station of the automatic production line from the database and sends the rated time interval and the initial time interval to the clock synchronization controller;

S1024, when the product detection equipment trigger controller generates a detection trigger signal, acquiring detection action execution time of the product detection equipment to be triggered corresponding to the product detection equipment trigger controller in real time;

and S1026, sending the time difference of detection action execution between the product detection devices corresponding to the product detection device trigger controllers to the clock synchronization controller.

The working principle of the technical scheme is as follows: the upper computer corresponding to the clock synchronous controller can initialize the product detection equipment trigger controller of the product detection station on the automatic production line. Initialization is an important preparatory step that ensures that all trigger controllers are in a known, unified state, so that subsequent data acquisition and measurement processes can be initiated accurately and reliably.

After the initialization is completed, the system enters a commissioning phase. At this stage, the upper computer controls the product detection equipment to trigger the controller to generate a detection trigger signal to simulate the operation in the actual production environment.

Through the commissioning, the system can acquire two key time information:

a. Initial time interval: the system will measure and record the time interval of the trigger action between each two adjacent product detection station trigger controllers. The time interval reflects the cooperative efficiency of the operation among stations and is an important index for evaluating the performance of the production line.

B. Detecting a time difference in performance of the action: when the trigger controller sends out a detection trigger signal, the system can acquire the execution time of the detection action of the corresponding product detection equipment in real time. By comparing the trigger signal emission time with the time at which the device actually performs the detection action, the time difference can be calculated. The above time difference reflects the response time of the device from receiving the trigger signal to actually performing the detection action, which is critical for evaluating the performance of the device and optimizing the flow of the production line.

The working principle of the technical scheme is that the system is ensured to start from a unified state through initialization setting, and then key time information is collected in the test operation process, wherein the key time information comprises the time interval of the trigger action between stations and the response time of the equipment detection action. The information provides important data support for subsequent production line optimization, clock synchronization adjustment and equipment performance evaluation.

The product detection device trigger controller is then initialized to ensure that all devices start from a standard or clear state. After the initialization is completed, the upper computer controls the conveying device of the automatic production line to perform trial operation according to a set conveying speed. Conditions in the actual production environment are simulated to collect accurate time data. In the process of test operation, the upper computer controls the product detection equipment trigger controllers corresponding to each product detection station to generate detection trigger signals. The above signal is a signal simulating the moment in actual production when the detection device needs to be triggered. At the same time, the system will acquire and record the trigger action time interval between each two adjacent product detection station trigger controllers, which is defined as the initial time interval.

To evaluate the performance and efficiency of the production line, the upper level would retrieve from the database the nominal time interval of the product inspection stations, which is theoretically the optimal time interval that should be maintained between two adjacent stations. The nominal time interval and the actual measured initial time interval are sent together to the clock synchronization controller for subsequent analysis and adjustment. When the trigger controller of the product detection device generates a detection trigger signal, the system can acquire the detection action execution time of the product detection device corresponding to the trigger controller in real time. The above data is critical to understanding equipment response time and line flow. According to the acquired detection action execution time of the product detection equipment, the system can calculate the time difference of detection action execution between the product detection equipment corresponding to each product detection equipment trigger controller. The above time difference reflects the time from the issuance of the trigger signal to the actual execution of the detection action by the device.

Finally, the time difference of the execution of the detection action between the corresponding product detection devices of each product detection device trigger controller is sent to the clock synchronization controller. The data will be used for further analysis and to optimise the clock synchronisation process of the production line to improve production efficiency and ensure co-operation between the devices.

The technical scheme has the effects that: by initializing the product detection device trigger controller, it is ensured that the device starts operating in a standard or expected state, which provides an accurate starting point for subsequent clock synchronization and data acquisition. Initialization procedure the above-described solution helps to eliminate any uncertainty or error that may have been left in previous operations or settings. The method and the device have the advantages that the initial time interval between the triggering actions of the trigger controllers of the product detection equipment of every two adjacent product detection stations is acquired in the test running process, the technical scheme is favorable for accurately grasping the cooperative working time difference between different stations on the production line, and data support is provided for the optimization of the production line.

The time difference of detection action execution between the corresponding product detection devices of each product detection device trigger controller is obtained, so that the actual time required by the detection devices to execute detection after receiving the trigger signals can be revealed. Through accurate grasp of the trigger action time interval and the detection action execution time difference, a production line manager can more effectively adjust cooperative work among stations, waiting time and resource waste are reduced, and therefore the operation efficiency of the whole production line is improved. The data can also be used for predicting and preventing potential fault points, equipment maintenance is performed in time, and stable operation of a production line is ensured.

On the other hand, by initializing the trigger controller of the product detection device and performing test operation after the initialization is completed, it is ensured that all devices are in a uniform starting state. The technical scheme is beneficial to eliminating the influence possibly brought by the previous operation and providing an accurate reference for the subsequent data acquisition and clock synchronization. In the process of test run, the product detection equipment trigger controllers corresponding to each product detection station are controlled to generate detection trigger signals, so that the time interval between every two adjacent product detection station trigger actions can be accurately acquired, and the data are important for understanding the cooperative work between stations on the production line. The technical scheme is beneficial to evaluating whether the actual running condition of the production line accords with the expectation or not and provides powerful data support for the optimization of the production line.

The detection action execution time of the product detection equipment is acquired in real time, and the running condition of each equipment can be accurately mastered, so that the method has important significance for timely finding and solving the problems and improving the production efficiency. By acquiring the time difference of detection action execution between the corresponding product detection devices of each product detection device trigger controller, the cooperative efficiency between the devices can be deeply known, and a basis is provided for further optimization of the production line. All collected data are sent to the clock synchronization controller, and the technical scheme is favorable for realizing global clock synchronization, so that each device on the production line can be ensured to perform correct operation at correct time, and the overall efficiency and stability of the production line are improved.

In summary, the technical scheme provides powerful data support for clock synchronization, flow optimization and equipment maintenance of an automatic production line by initializing and accurately measuring the time difference, and the technical scheme is beneficial to improving the overall efficiency and the product quality of the production line. Meanwhile, the technical scheme provides comprehensive data support for optimization and clock synchronization of an automatic production line through accurate initialization and test operation, real-time data acquisition and deep time interval and time difference analysis, and the technical scheme is beneficial to improving the operation efficiency and stability of the production line.

According to one embodiment of the invention, a static time interval adjustment parameter and a dynamic time interval adjustment parameter triggered by a product detection device are obtained according to the triggering time information of the product detection station and the time information of the product detection device of the product detection station of the automatic production line, and the method comprises the following steps:

Specifically, the detailed steps of the above technical solution in this embodiment include:

S201, the clock synchronous controller acquires static time interval adjustment parameters between triggering actions of the product detection equipment trigger controllers of two adjacent product detection stations according to a rated time interval and an initial time interval;

S202, the clock synchronization controller acquires initial dynamic time interval adjustment parameters between triggering actions of the product detection equipment triggering controllers of two adjacent product detection stations according to the time difference of detection action execution between the product detection equipment corresponding to each product detection equipment triggering controller; wherein the product detection device includes, but is not limited to, an area camera and a line camera.

The static time interval adjustment parameter is obtained as follows:

A1, comparing the rated time interval with an initial time interval to obtain a time difference between the rated time interval and the initial time interval; the value of the time difference is a positive value, and the initial time interval is smaller than the rated time interval, so that the preamble is triggered; the numerical value of the time difference is a negative value, which indicates that the initial time interval is larger than the rated time interval, and the trigger is post-positioned;

a2, monitoring instruction execution response delay of the upper computer to the product detection equipment triggering controller in real time;

And A3, acquiring a static time interval adjustment parameter by utilizing the time difference between the rated time interval and the initial time interval and the instruction execution response delay of the upper computer to the product detection equipment trigger controller, wherein the static time interval adjustment parameter is acquired by the following formula:

Wherein n represents the number of instructions for the upper computer to send instructions to the product detection equipment trigger controller in the test operation process; v _i represents the transfer speed of the pipeline conveyor of the automated line at the time of the ith instruction issue; t ₀ represents the maximum instruction execution response delay allowed at the transfer speed of the pipeline carousel; l represents the maximum offset distance of the product conveyed by the conveyor belt allowed under the detection synchronization standard of the product detection equipment; sigma represents a delay compensation coefficient; t _i represents the instruction execution response delay when the ith instruction is sent; s _e denotes a nominal time interval.

Meanwhile, the dynamic time interval adjustment parameter is obtained as follows:

Step B1, monitoring the execution response time of the product detection equipment corresponding to each product detection equipment trigger controller in real time when the product detection equipment trigger controller triggers the product detection equipment to detect the product;

Step B2, acquiring the time difference of detection action execution between the product detection devices corresponding to the product detection device trigger controllers according to the execution response time of the product detection devices corresponding to the product detection device trigger controllers;

and B3, acquiring initial dynamic time interval adjustment parameters between triggering actions of the product detection equipment triggering controllers of two adjacent product detection stations by utilizing the time difference of detection action execution between the product detection equipment corresponding to each product detection equipment triggering controller, wherein the initial dynamic time interval adjustment parameters are acquired by the following formula:

The working principle of the technical scheme is as follows: the clock synchronization controller first receives and compares the nominal time interval with the initial time interval. The difference or proportional relationship of these two time intervals reflects the difference between the actual trigger action and the ideal state. By this comparison, the clock synchronization controller can calculate a static time interval adjustment parameter that is used to adjust the fixed time difference between the inter-station trigger controllers to more closely approximate the nominal or ideal state. In addition to static adjustment, dynamic coordination between devices during actual detection needs to be considered. The clock synchronization controller collects and analyzes the detection action execution time difference between each product detection device trigger controller and its corresponding detection device (such as an area array camera and a line array camera). The above time difference reflects the dynamic performance of the device in actual operation. By analyzing the data, the clock synchronization controller can calculate an initial dynamic time interval adjustment parameter to optimize the real-time cooperative work of the inter-station trigger controllers.

And comparing the rated time interval with the initial time interval acquired in the test operation stage by the system in the acquisition process of the static time interval adjustment parameters. The time difference between the two is obtained by comparison. If the time difference is positive, this means that the initial time interval is smaller than the nominal time interval, i.e. the triggering action occurs earlier than ideal (trigger preamble). If the time difference is negative, it means that the initial time interval is greater than the nominal time interval, i.e. the trigger action occurs later than the ideal state (trigger post). Meanwhile, the system monitors the instruction execution response delay after the upper computer sends an instruction to the product detection equipment trigger controller in real time. The reaction time of the system in actual operation is known in order to more accurately adjust the trigger time interval. And calculating a static time interval adjustment parameter by using the time difference between the rated time interval and the initial time interval and the instruction execution response delay of the upper computer to the product detection equipment trigger controller. The formula considers a plurality of factors including the transmission speed of a pipeline conveyor belt of an automatic production line, the maximum instruction execution response delay, the maximum offset distance allowed under the detection synchronization standard of product detection equipment, the delay compensation coefficient and the like, so as to ensure that the calculated static time interval adjustment parameters can accurately reflect the actual conditions and demands of the production line.

Meanwhile, in the process of acquiring the dynamic time interval adjustment parameters, the system can dynamically adjust the trigger time interval according to actual conditions through real-time monitoring and calculation, so that the operation efficiency of the production line is optimized. The technical scheme is favorable for ensuring smoother cooperative work among all product detection devices and reducing production efficiency reduction caused by device response time difference. The technical scheme can adapt to various changes on the production line, such as equipment performance fluctuation, product type replacement and the like, so that the production line has higher flexibility and adaptability. By accurately adjusting the triggering time interval, the consistency of the product in the detection process can be ensured, thereby improving the quality control level of the product.

The technical scheme has the effects that: by accurately calculating the static and dynamic time interval adjustment parameters, the triggering time between different stations on the production line can be optimized, unnecessary waiting and delay are reduced, and therefore production efficiency is improved. The dynamic time interval adjustment parameters enable the production line to better cope with changes in the actual production process, such as equipment performance fluctuation, material flow rate change and the like, so that efficient and stable operation is maintained. By optimizing the cooperative work of the trigger controllers, the conflict and interference among the devices can be reduced, so that the detection devices on each station can be matched and work more smoothly. The accurate time interval adjustment parameters provide a data basis for realizing higher-level automation and intelligent management of the production line, and the technical scheme is beneficial to enterprises to realize intelligent manufacturing and application of industrial Internet.

Meanwhile, by accurately calculating the static time interval adjustment parameters, the trigger action of the trigger controller of the product detection equipment can be ensured to be closer to the rated or ideal state, so that the trigger precision is improved. The adjusted triggering time interval can enable cooperation among all stations on the production line to be smoother, unnecessary waiting and conflict are reduced, and production efficiency is improved. By monitoring and compensating the response delay of the instruction execution in real time, the influence caused by the system delay can be reduced, and the stability and the reliability of the production line are enhanced. The technical scheme is more accurate in triggering control, and is helpful for ensuring the consistency of products in the detection process, so that the quality control level of the products is improved.

On the other hand, through real-time monitoring and calculation, the system can dynamically adjust the triggering time interval according to actual conditions, so that the operation efficiency of the production line is optimized. The technical scheme is favorable for ensuring smoother cooperative work among all product detection devices and reducing production efficiency reduction caused by device response time difference.

And finally, adjusting the trigger execution time interval of the trigger controller of the product detection equipment of the product detection station by utilizing the dynamic time interval adjustment parameter and the static time interval adjustment parameter which are adjusted in real time. This ensures that the trigger control is more accurate and efficient.
