Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

As shown in accompanying drawings 1 to 3, the automatic production line problem intelligent processing system includes a master control system electrically connected to the control system of the production equipment and an alarm device electrically connected to the master control system, and the master control system includes a problem decision-making module And a monitoring module for monitoring whether there is a safety problem in the production equipment. The monitoring module transmits the detection information to the general control system, and then the problem decision module judges the problem level of the safety problem according to the detection information, and finally the general control system according to the problem The class invokes the corresponding actions from the problem decision module.

The present invention realizes the intelligent optimization of the safety problem response processing process by introducing the intelligent response processing method of the safety problem in the automated production line, shortens the safety problem elimination cycle, improves the production efficiency, and reduces the maintenance work labor intensity and production cost. Compared with the traditional security problem handling method, the present invention uses the communication link of the automation system and the command execution system to finely optimize the security problem processing flow, avoiding the defect that the operation error is considered under complex equipment related conditions, and avoiding a large number of repetitions by maintenance personnel Sexual labor, significantly shorten the recovery cycle of the production line, and improve the overall production efficiency of the production line.

In this embodiment, the control system of the production equipment is a distributed system, each equipment system is loosely coupled and operates independently, and the equipment-side control system only executes limited legal instructions; the security issues include equipment-level security issues, unknown security issues of the production system, etc. Issues and production system known security issues;

If the problem decision-making module judges that it is a safety problem at the equipment level, the treatment measure is to activate the emergency button, and all equipment will be stopped immediately to ensure the safety of on-site personnel and equipment.

If the problem decision-making module judges that the general control system has an unknown safety problem or a known safety problem, the treatment measures are that the control system of the faulty equipment stops accepting instructions, automatically stops or stops after performing necessary actions, and the alarm device sends out an alarm to remind on-site personnel to intervene , which is convenient for on-site personnel to perform manual processing.

Specifically, when the problem decision-making module judges that the general control system has an unknown safety problem, the general control system sends a recovery command to the relevant non-faulty equipment after obtaining the fault information, instructing the relevant equipment to perform recovery actions at a safe speed and reach the ready-to-run state , and wait for the execution command.

In this embodiment, when the problem decision-making module determines that the general control system has a known safety problem, the general control system sends a slow command to the relevant non-faulty equipment according to the equipment association relationship and the current operating status of the equipment after obtaining the fault information.

After the master control system obtains the fault information, it sends a slow speed command to the relevant non-faulty equipment according to the equipment association relationship and the current operating status of the equipment. Specifically, if the action currently performed by the system device is time-sensitive, instruct the device to perform a fault response action; if the action currently performed by the system device is not time-sensitive, instruct the device to continue to perform the current action at a safe speed.

In this embodiment, the master control system communicates with the control system of the production equipment through a communication link, which is used for two-way information communication between the equipment control system and the master control system

In this embodiment, the problem decision-making module independently generates processing measures after analyzing the discovered security problems, and distributes the processing measures to related equipment, and the control system controls the production equipment to execute the processing measures.

In actual production applications, the master control system learns whether there is a safety problem in the equipment and the specific description of the safety problem through the communication link. The master control system can obtain the safety issues of one or more equipment at the same time, and make decisions based on the occurrence of safety issues of all equipment in the production line.

Combined with the system safety problem processing process model shown in Figure 2, in practical applications, after the master control system learns that one or more devices have a safety problem, it first sends out an alarm to inform the operator that the production line is faulty, and then distinguishes whether the safety problem is Known or unknown. If it is an unknown security problem, the system decides on the security problem processing procedure, and then distributes relevant instructions to devices related to the security problem. After the relevant equipment receives the fault handling instruction, it executes the safety problem handling action according to the instruction. After the equipment completes these actions, the maintenance personnel will intervene to manually solve the fault problem. After the troubleshooting is completed, maintenance personnel resume the automatic operation of the production line. If it is a known security problem, the system decides on the security problem handling process, and then distributes relevant instructions to the devices related to the problem. After the relevant equipment receives the fault handling instruction, it executes the safety problem handling action according to the instruction. In general, such safety issues can be handled by the production line automation system autonomously. After the equipment executes these actions, the master control system automatically resumes the automatic operation of the production line.

As shown in FIG. 3 , the processing flow of the device security problem involved in the present invention is shown. This process generally occurs in the debugging stage of production equipment. Before the equipment can run stably, the operator usually operates in front of the equipment operation panel. Production equipment should be equipped with emergency stop buttons. Once the operator finds that there is a safety problem with the equipment, he will immediately press the emergency stop button, and the equipment will stop immediately to ensure the safety of the equipment and on-site personnel.

The content not described in detail in the specification belongs to the prior art known to those skilled in the art.

The above-mentioned embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be realized in other ways, and any obvious replacements are within the scope of protection of the present invention without departing from the concept of the technical solution.
