Based on the hardware structure, the embodiment of the station fault judging method is provided.

Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a method for determining a station failure according to the present invention.

In a first embodiment, the method for judging station faults includes the following steps:

step S10, station switching value information of the numerical control machine is obtained, the station switching value information is analyzed, and a current station processing starting time point is obtained.

It should be noted that, the execution body of the embodiment may be a station fault judging device, or may be other devices that may implement the same or similar functions, which is not limited in this embodiment, and in this embodiment, the station fault judging device is described as an example.

It should be understood that the station switching value information of the numerical control machine refers to the collection and output of station discontinuous signals, including remote control collection and remote control output, which has two states of 0 and 1, which is the switching property in a digital circuit, and electrically refers to the on and off of the circuit or the on and off of contacts. The on and off are the most basic and typical functions of the electric appliance, and the general switching value device realizes the output of switching value information through an internal relay, wherein the output of the switching value information refers to digital value output, and the output of 0 or 1 is used for controlling switching signals of an external signal lamp, a relay and the like. The switching value output functions are two types, namely output according to bytes and output according to bits, the switching value information mainly refers to the opening quantity and the opening quantity, and refers to auxiliary points carried by a device, the numerical control machine is a short name of a numerical control machine (Computer numerical control machine tools, CNCMT) and is an automatic machine provided with a program control system, the control system can logically process a program defined by control codes or other symbol instructions, decode the program, and the program is represented by coded numbers, input into the numerical control device through an information carrier, send various control signals through the numerical control device through operation processing, control the action of the machine, and automatically process parts according to the shape and the size required by drawings.

It can be understood that the analyzing the station switching value information refers to converting the content in the station switching value information when each station processes a workpiece, and extracting information required by the converted information, for example, the station switching value information of the numerical control machine tool has type a information, type B information and type C information, and only type a information is required in the post operation processing, and type B information and type C information are not required, at this time, the type a information is extracted from the content converted information in the station switching value information, and the type a information is the processing starting time point of the current station.

In specific implementation, the station fault judging equipment acquires station switching value information of the numerical control machine tool, analyzes the station switching value information, and acquires a current station processing starting time point.

And step S20, storing the processing starting time point of the current station into a database to obtain the current information of the database.

It should be understood that the database refers to a warehouse that organizes, stores and manages data according to a data structure, and is also a collection of large amounts of data that are stored in a computer for a long period of time, are organized, sharable and uniformly managed, and have a large storage space, and can store millions, tens of millions and even hundreds of millions of data, but the database does not store data randomly, is regular, otherwise the query efficiency is low, for example, the data can be stored according to the type of the data, or the database is a new method and technology for managing the data according to the time of storing the database, etc., and can organize the data more appropriately, maintain the data more conveniently, control the data more tightly and use the data more effectively.

It can be understood that the current information of the database refers to information obtained by fusing initial information in the database with stored target information after the current station processing starting time point is obtained, for example, the initial information in the database is information a and information B, and the stored target information is information C, so that the information stored in the database includes three types of information a, information B and information C, and the stored information is the current information of the database.

In specific implementation, the station fault judging device stores the processing starting time point of the current station into a database to obtain the current information of the database.

And step S30, obtaining the time required for processing the workpiece according to the current information of the database.

It should be understood that the time required for obtaining the workpiece according to the current information in the database refers to the time required for extracting the workpiece from the current information stored in the database, the basis of the extraction is that the time required for processing the workpiece according to the number of the workpiece at the current station can be obtained, for example, the number of the workpiece is 001, the time required for processing the workpiece is 10 minutes, and thus 10 minutes is the time required for processing the current workpiece.

In specific implementation, the judging equipment of the station faults obtains the time required for processing the workpiece according to the current information of the database.

Step S40, acquiring threshold time of the adjacent stations, and determining whether the current station is a fault station according to the threshold time, the processing time point of the current station in the database and the time required for processing the workpiece so as to realize judgment of station faults.

It should be understood that, the threshold time of the adjacent station refers to a starting time from the end of the current station to the next station, because the processing of the workpiece passes through a relatively large number of processes, in this implementation, the processing process of the workpiece is specifically classified into hole position detection, clamping, drilling, deburring and sending inspection, after each processing process, the processed workpiece is qualified, for example, the current station is subjected to drilling treatment, the next station is subjected to deburring treatment, the drilling start processing time point is 2020/8/6 16:22:10, the drilling time is 2 minutes, and the waiting time from drilling to deburring is 30 seconds, then the target time is 2020/8/6/16:24:40, and if the deburring operation does not start to process the current workpiece in the target time point, the drilling station is failed, thereby realizing judgment of station failure.

In specific implementation, the judging device of the station fault acquires the threshold time of the adjacent station, and determines whether the current station is a fault station according to the threshold time, the processing time point of the current station in the database and the time required for processing the workpiece so as to realize the judgment of the station fault.

According to the embodiment, station switching value information of a numerical control machine tool is acquired, and is analyzed, so that a current station processing starting time point is acquired; storing the processing starting time point of the current station into a database to obtain the current information of the database; obtaining the time required for processing the workpiece according to the current information of the database; and acquiring the threshold time of the adjacent stations, and determining whether the current station is a fault station according to the threshold time, the processing time point of the current station in the database and the time required for processing the workpiece so as to judge the station fault. According to the invention, the station switching value information of the numerical control machine tool is acquired, the station switching value information is analyzed, the corresponding processing starting time point of the current station is acquired, the processing starting time point of the current station is stored in the database, the time required for processing the workpiece is acquired from the stored database, the threshold time of the adjacent station is acquired, and whether the current station is faulty or not is determined according to the processing starting time point of the current station, the time required for processing the workpiece and the threshold time of the adjacent station, so that the position of the station fault can be rapidly determined, and the judging efficiency of the station fault is improved.

In an embodiment, as shown in fig. 3, a second embodiment of the method for determining a station failure according to the present invention is provided based on the first embodiment, and before step S10, the method further includes:

and step S01, respectively initializing the communication mode of the switching value information acquisition module and the communication mode of the signal receiving module to obtain an initialized switching value information acquisition module and an initialized signal receiving module.

It can be understood that the switching value information acquisition module refers to a module for acquiring information of a numerical control machine tool, the switching value information acquisition module acquires Socket communication based on a TCP/IP protocol through Ethernet, the switching value information acquisition module can act as a device end for sending state information of the numerical control machine tool, the signal receiving module refers to a device end for receiving information sent by the switching value information acquisition module, after receiving the switching value information, the switching value information is analyzed, fault judgment is carried out on the station based on a hierarchical analysis method, and the hierarchical analysis method (Analytic Hierarchy Process, AHP) refers to a decision method for carrying out qualitative and quantitative analysis on the basis that elements related to decision are always decomposed into layers such as targets, criteria and schemes.

It should be understood that, the initializing the communication mode of the switching value information acquisition module and the communication mode of the signal receiving module respectively refers to setting the communication mode of the switching value information acquisition module and the communication mode of the signal receiving module to be default, setting the control to be default, if the communication mode of the switching value information acquisition module and the communication mode of the signal receiving module are changed, the initialization is required to be set to be default, and the communication modes are simplex communication, half duplex communication and full duplex communication, for example, the communication mode of the switching value information acquisition module and the communication mode of the signal receiving module are all full duplex communication, but when other signals are transmitted, the communication mode of the signal receiving module is changed to be half duplex communication, and at this time, for the accuracy of data transmission, the signal receiving module needs to be initialized to restore the communication mode of the signal receiving module to the default full duplex communication mode.

In specific implementation, the station fault judging device initializes the communication mode of the switching value information acquisition module and the communication mode of the signal receiving module respectively to obtain an initialized switching value information acquisition module and an initialized signal receiving module.

Step S02, IP information and port number information of the initialized signal receiving module are obtained, and connection between the initialized switching value information acquisition module and the initialized signal receiving module is established according to the IP information and the initialized port number information.

It should be understood that, the Socket port refers to a port for performing bidirectional communication between application processes on different hosts in the network, which is also one end of process communication on the network, and provides a mechanism for an application layer process to exchange data by using a network protocol, where the Socket port is connected with the application process, and the Socket port is connected with a network protocol stack, which is not only a port for an application program to perform communication through the network protocol, but also a port for the application program to interact with a network protocol root.

It may be understood that the obtaining the IP information of the initialized signal receiving module refers to obtaining an IP address of the initialized signal receiving module, where the IP address is a unified address format provided by an IP protocol, and allocates a logical address to each network and each host on the internet, so as to mask differences of physical addresses, obtaining port number information of the initialized signal receiving module refers to obtaining port number information of the initialized signal receiving module, where the ports are classified into two types of logical ports and physical ports, where the physical ports are used for connecting interfaces between physical devices, the logical ports refer to ports used for differentiating services in a logical sense, such as 80 ports used for browsing web services, 21 ports used for FTP services, etc., and service ports in the TCP/IP protocol differentiate different services through different logical ports.

It should be understood that establishing the connection between the initialized switching value information acquisition module and the initialized signal receiving module according to the IP information and the port number information means that after the information acquisition module obtains the IP information and the port number information of the signal receiving module, the information acquisition module generates a corresponding IP of the same segment according to the IP address in the signal receiving module, generates a corresponding receiving port according to the port number information of the signal receiving module, after the IP information and the port number information of the two meet the connection conditions, the switching value information acquisition module sends a connection request to the signal receiving module, and after the signal receiving module receives the connection request, the switching value information acquisition module and the signal receiving module can be connected.

In a specific implementation, the station fault judging device accumulates the threshold time, the station processing starting time point and the time required for processing the workpiece to obtain a target processing time point.

Step S403, determining whether the target processing time point is consistent with the processing time point of the next station.

It may be understood that the determining whether the target processing time point is consistent with the next station processing time point refers to determining whether the time calculated by the threshold time, the station processing start time point, and the time required for processing the workpiece is consistent with the time point recorded in the database at which the next station processing starts the workpiece, where the time point at which the next station processing starts the workpiece may be obtained from a relationship map of the processing workpiece number and the corresponding processing time stored in the database, where the relationship map includes the processing workpiece number, the processing time corresponding to the processing workpiece number, and other information.

In specific implementation, the station fault judging device judges whether the target processing time point is consistent with the next station processing time point.

Step S404, if the target processing time point is inconsistent with the processing time point of the next station, determining that the current station is a fault station.

It will be appreciated that the determination that the current station is a fault station is determined according to the fact that the target processing time point is inconsistent with the processing time point of the next station, for example, the threshold time set between the hole position detection station and the clamping is 1 minute, the processing time point of the hole position detection station is 2020/7/3009:56:15, the time required for the hole position detection station to process a workpiece is 3 minutes, the calculated time point of the clamping to start processing the workpiece is 2020/7/30:10:00:15, but the time point obtained from the relation mapping table of the processing workpiece number and the corresponding processing time stored in the database is 2020/7/30:10:01:45, and then the hole position detection station is a fault station.

In a specific implementation, if the target processing time point is inconsistent with the next processing time point, the station fault judging device determines that the current station is a fault station.

It should be understood that before the threshold time, the station processing starting time point and the time required for processing the workpiece are accumulated to obtain the target processing time point, a fault judgment timer is further required to be started, and whether the next station is processed or not is judged according to the fault judgment timer; and if the next station does not process, the step of accumulating the threshold time, the station processing starting time point and the time required for processing the workpiece to obtain a target processing time point is executed.

It can be understood that after the threshold time of the adjacent stations is obtained, whether the current station is a fault station or not is determined according to the threshold time, the processing time point of the current station in the database and the time required for processing the workpiece, and if the current station is determined to be the fault station, the current information of the database is updated to obtain the target information of the database; analyzing the database target information to obtain station fault information, starting alarm equipment, and maintaining the current station according to the station fault information.

In the embodiment, by starting a fault judgment timer, judging whether the next station is processed or not according to the fault judgment timer; if the next station is not processed, the step of accumulating the threshold time, the station processing starting time point and the time required for processing the workpiece to obtain a target processing time point is executed; acquiring a processing time point of a next station; accumulating the threshold time, the station processing starting time point and the time required for processing the workpiece to obtain a target processing time point; judging whether the target processing time point is consistent with the next station processing time point or not; and if the target processing time point is inconsistent with the next station processing time point, determining that the current station is a fault station. According to the embodiment, whether the next station starts to process or not is judged through the fault judgment timer, if the next station does not process, the threshold time, the station processing starting time point and the time required for processing the workpiece are accumulated to obtain the target processing time point, when the next station starts to process, the obtained target processing time point is calculated to be inaccurate, so that accuracy of obtaining the processing time point is improved, the calculated target time point is compared with the next station processing time point, and whether the current station is the fault station or not is determined, and therefore judging efficiency of station faults is improved.

It should be understood that, the threshold time of the adjacent station refers to a starting time from the end of the current station to the next station, because the processing of the workpiece passes through a relatively large number of processes, in this implementation, the processing process of the workpiece is specifically divided into hole position detection, clamping, drilling, deburring and sending inspection, after each processing process, the processed workpiece is a qualified workpiece, for example, the current station is subjected to drilling treatment, the next station is subjected to deburring treatment, the drilling start processing time point is 2020/8/6:16:22:10, the drilling time is 2 minutes, and the waiting time from drilling to deburring is 30 seconds, then the target time should be 2020/8/6:16:40, if the deburring operation does not start to process the current workpiece within the target time point, the drilling station is failed, so as to realize judgment of station failure.
