Description

Technical Field

[0001] The present invention relates to the technical field of smart factories, and in particular to a smart factory production equipment monitoring system. Background Art

[0002] At present, most of the smart factories are basically using integrated technology to use data collectors (including some special sensors, such as voltage, current sensors, temperature sensors, etc.) to collect the basic operating data of production equipment in each flow process to determine the operating status of the production equipment and the operating status of the entire production line. In particular, when a certain production equipment on the production line fails, it will have a certain impact on the subsequent production equipment, and these impact settings are irreversible. However, when any production equipment fails, the current technical means basically use the production equipment that has an error to adjust the production equipment. This will result in no corresponding regulation of the subsequent production equipment during regulation, resulting in inconsistent regulation. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a schematic diagram of the system framework principle of the present invention. DETAILED DESCRIPTION

[0038] The present invention is described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1 , the production equipment on the production line has relative independence when it is running, but this does not mean that there is no linkage between the production equipment on the production line. On the one hand, independence can only mean that the production equipment can be started and operated under the rated parameters to maintain the normal operation of the equipment, but on the other hand, since the production equipment on the production line is running, it is necessary to consider the operating status of the production equipment in the next flow sequence, so that the entire production line can maintain stable operation, which means that the production equipment on the production line has linkage with the production flow sequence. The linkage shows that when a production equipment fails, it may have different degrees of impact on the subsequent production equipment. For example, when the voltage at a certain production equipment fluctuates, the voltage flowing through the subsequent production equipment will also fluctuate to varying degrees, and these jitters are not completely consistent. Generally, the jitter continues to decrease with the production flow of the production line. Therefore, if you want to achieve consistent regulation, the corresponding regulation values ​​of each affected production equipment are inconsistent when they are regulated. This application fully considers the impact of each production equipment on subsequent production equipment when a failure occurs, and fully considers the impact on several subsequent production equipment. According to these impacts, the control plan is set accordingly, and the impact of different production equipment can be controlled through the control plan to make the overall control consistent.

[0040] Therefore, the present application provides the following technical solutions: a smart factory production equipment monitoring system, including: a configuration module; and an actuator processing module; the configuration module includes a configuration unit and a stream actuator, the configuration unit is used to integrate and configure the monitoring elements of the equipment on the production line in sequence according to the production flow order, each production equipment corresponds to a monitoring node, and the monitoring nodes are connected to form an execution series through the stream actuator; the execution processing module has: a first execution configuration unit, which writes the monitoring node into the logic program in the production flow order according to the series code formed by the execution series of the stream actuator to form a logic chain; a second execution configuration unit, connected to the first execution configuration unit, obtains the monitoring elements in sequence according to the logic chain The basic equipment parameters and floating parameters of the production equipment form the benchmark data required for monitoring, and the benchmark data is written into the corresponding monitoring node under the logic chain; a control logic configuration unit is connected to the second execution configuration unit, and the control logic configuration unit includes: according to the logic chain, a collection unit is formed under each monitoring node for real-time collection of the operating data of the production equipment corresponding to the monitoring node; a comparison unit is used to compare the operating data of the production equipment with the benchmark data; a control unit is used to generate a number of control plans of different levels according to the comparison results of the comparison unit; a control unit forms a dynamic adjustment plan based on the chain reaction caused by the control instructions corresponding to the control plans of different levels on the subsequent monitoring nodes.

[0041] Furthermore, the monitoring element integrated configuration refers to the collection of necessary operating parameters of production equipment during operation by setting corresponding collectors through integrated technology and transmitting them to the monitoring node. It can be understood that the collector can be a sensor, a counter or a photoelectric sensor, and can be adaptively configured for different production equipment.

[0042] Furthermore, the stream executor has: a transmission part for transmitting and connecting the collectors under each monitoring node in series according to the transmission mode set in the integrated technology; a control and control connection part for transmitting the instructions required for controlling the subsequent monitoring nodes when a chain reaction is generated on the subsequent monitoring nodes according to the production flow sequence according to the different levels of control plans formed by the control part of each monitoring node. It should be noted that the operation data corresponding to each production equipment is not from a single source. For example, the indicators that need to be monitored during the operation of the production equipment include voltage, current, temperature, rotation speed of the drive mechanism, etc. Different indicators correspond to different types of collectors, and these collectors are transmitted to the same monitoring node for processing through wired or wireless transmission.

[0043] It should also be noted that although the production equipment is arranged and installed in the order of production flow, it does not mean that when regulating, only two adjacent monitoring nodes are connected. The present application sets a control node formed by a programmable controller at each monitoring node. The control node connects different types of collectors together by wire or wireless means. At the same time, the control nodes are connected to the master control terminal, and the connection between any two monitoring nodes is realized through the master control terminal. In this way, each control node can realize the collection, processing and abnormal monitoring of the real-time operation data of the corresponding production equipment, and regulate the abnormal monitoring according to the pre-set regulation plan. At the same time, through the connection with the master control terminal, the regulation of other monitoring nodes with chain reactions can be realized.

[0044] It should be noted that the logic program is run on a programmable controller.

[0045] Furthermore, the transmission unit is used to transmit different collectors to the monitoring node through wired or wireless transmission according to the set serial code.

[0046] Furthermore, the control serial connection unit is used to connect two or more adjacent monitoring nodes in a wired or wireless manner according to the set control serial connection code in the production flow order;

[0047] Furthermore, when different levels of control plans produce a chain reaction on subsequent monitoring nodes according to the production flow sequence, the control serial codes connected to the subsequent monitoring nodes are different.

[0048] Furthermore, the control serial connection unit has a control serial connection code generation unit which is set according to the chain reaction level formed when a chain reaction is generated on subsequent monitoring nodes according to the production flow sequence according to different levels of control plans, and the control serial connection code generation unit forms a unique corresponding control serial code according to the chain reaction level.

[0049] Furthermore, the logic program has a configuration part and a program part, wherein the configuration part has a plurality of configuration areas, each of which has a header area and a plurality of parallel setting areas, each of which is used to write a serial code to form a first logic chain based on wired or wireless control for different collectors, and the first logic chain is linked to the header area;

[0050] The header area is used to write the control serial code to form a second logical chain between two or more monitoring nodes based on a wired or wireless control method, and the second logical chain is used to connect two or more adjacent monitoring nodes based on the production flow sequence.

[0051] Furthermore, the basic equipment parameters refer to the rated parameters of the production equipment during operation;

[0052] Floating parameters refer to the allowable deviation values ​​of production equipment under different operating conditions, and a deviation range is formed according to the allowable deviation values;

[0053] The benchmark data is a benchmark that represents the operating status of the equipment, formed by considering the allowable deviation value and rated parameters of the production equipment under different operating conditions.

[0054] Furthermore, the head area has a plurality of parameter setting areas arranged in parallel, and the parameter setting areas are used to connect two different monitoring nodes in series according to different control serial codes; and to form a plurality of logical chains, and the plurality of logical chains constitute a second logical chain.

[0055] Furthermore, the control unit has:

[0056] A judging unit, used to judge the chain reaction caused by different levels of control plans on subsequent monitoring nodes when they are executed, so as to judge the interval spanned by the chain reaction; and to determine the control value of the chain reaction on each monitoring node within each of the intervals according to the multiple influence ranges included in the control plan and the influence value corresponding to each influence range;

[0057] The dynamic controller is used to control the actuator according to the production of the interval crossed by the chain reaction and the number corresponding to the crossed interval, and to perform one-to-one control on the corresponding monitoring nodes in the interval in turn by calling the control value obtained by the judgment unit.

[0058] It should be noted that the range spanned by the chain reaction refers to the range of impact on subsequent production equipment based on the production flow sequence when the current production equipment fails.

[0059] The present invention divides the production equipment on the production line into several equipment nodes according to the production flow sequence. Each equipment node has relatively independent operation capabilities. Through integration technology, a collector that can collect basic operation data when the production equipment is running is set on the equipment node. The basic data of the production equipment operation is collected to judge the operation status of the production equipment.

[0060] This application fully considers the impact of each production equipment on subsequent production equipment when a failure occurs, and fully considers the impact on several subsequent production equipment. According to these impacts, the control plan is set accordingly, and the impact of different production equipment can be controlled through the control plan to make the overall control consistent.
