Description

Technical Field

[0001] The invention belongs to the technical field of gas cylinder status monitoring systems, and in particular relates to a gas cylinder weight dynamic monitoring system based on real-time data collection. Background Art

[0002] Electronic special gases (abbreviated as electronic special gases) are an important branch of special gases and are indispensable raw materials for the production of integrated circuits (ICs), flat display devices (LCD, LED, OLED), solar cells and other electronic industries. In the IC production process, there are almost more than 100 types of electronic gases used, and about 30 types are commonly used in the core process.

[0003] In the semiconductor manufacturing industry, chip production goes through hundreds of processes, which use a lot of special gases. Most special gases are flammable, explosive, highly toxic, and corrosive. In order to safely transport and use these dangerous gases, semiconductor factories will install electronic special gas systems, equipped with electronic special gas cabinets GC, gas distribution boxes VMB, special gas leak monitoring alarms and other special equipment.

[0004] At present, the use scenario is that during the gas supply process of gas cylinders, workers are not clear about the use of gas inside the cylinders. They have to use special detection instruments to manually detect the remaining amount of gas cylinders. Analyze whether the gas cylinder needs to be replaced based on the workers' experience. During the operation, workers are required to inspect the remaining amount of gas cylinders many times, resulting in a waste of manpower. At the same time, there are also cases where personnel fail to replace gas cylinders in time, resulting in interruption of gas supply in the entire IC production process, causing a decrease in product qualification rate. There is also a problem of re-loading the replaced cylinders, and the gas supply time cannot be ensured. At the same time, there is also a problem of manually opening the valve of the full gas cylinder too large, causing excessive gas pressure, causing damage to the valve in the pipeline. The existing technology relies too much on workers' experience, resulting in unstable product qualification rate and safety hazards on the production line. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a gas cylinder weight dynamic monitoring system based on real-time data acquisition; The purpose of the present invention can be achieved by the following technical solutions: A gas cylinder weight dynamic monitoring system based on real-time data collection, comprising: an information identification unit, a weight monitoring unit, and a real-time monitoring unit; The information identification unit is used to read the information of the steel cylinder and collect the information of the gas cylinder cabinet, and to verify the information of the steel cylinder and the gas cylinder cabinet through the MES system. If the steel cylinder information is consistent with the steel cylinder material information required by the gas cylinder cabinet, the MES system (manufacturing execution system, responsible for production management and scheduling, used to track and record the production conversion from raw materials to finished products) will issue a loading operation command to the steel cylinder corresponding to the steel cylinder information. If the steel cylinder information is inconsistent with the steel cylinder material information required by the gas cylinder cabinet, the MES system will issue a material replacement operation command to the steel cylinder corresponding to the steel cylinder information; The weight monitoring unit weighs the gas cylinder that has completed the loading operation command. If the weighing result is ≥ the set full bottle weight, the weight conversion system in the real-time monitoring unit will convert the collected weight data into the remaining gas in the bottle and display it on the page; the real-time monitoring unit will conduct systematic monitoring of the cylinder and upload the cylinder data to the MES system in real time. If the weighing result is less than the full bottle weight, the weight conversion system in the real-time monitoring unit will convert the collected weight data into the remaining gas in the bottle and display it on the page. And determine whether to switch the cylinder based on the remaining use time of the cylinder, and monitor the weight during subsequent use; The real-time monitoring unit includes a client management module, a measurement task generation module, a real-time measurement module, and a status inspection module; the client management module is used to obtain the real-time monitoring task, and parse the real-time monitoring task through a task analyzer to obtain the monitoring execution time and the monitoring object, and the monitoring object is the gas cylinder in the gas supply process of the gas cylinder cabinet; the measurement task generation module is used to send the address number of the weighing sensor corresponding to the monitored object to the program receiving unit through the data storage unit, and the program receiving unit generates a weight measurement task according to the location information of the monitored object, the monitoring execution time, and the address number of the weighing sensor; the real-time measurement module is used to establish a command frame for the weight measurement task through a dynamic monitoring platform, and the control module of the weighing sensor is connected to the dynamic monitoring platform according to the command frame, and the dynamic monitoring platform sends a control signal to the connected control module, and the control module executes the weight measurement task according to the control signal to obtain the weight data of the gas cylinder, and sends a feedback signal to the dynamic monitoring platform, and the dynamic monitoring platform controls the safety detection of the weight data of the gas cylinder and feeds back the detection result to the safety warning unit, the MES system, and the weight conversion system. The collected weight data is converted into the remaining gas in the bottle and displayed on the page; the state inspection module is used to perform multi-state event-driven parallel management on the dynamic monitoring platform, and the operating state of the dynamic monitoring platform includes idle state, parameter configuration state, interrupt state, measurement state, data transmission state, and safety detection state; The MES system issues a command to stop gas supply, and the corresponding gas cylinder cabinet stops the gas supply to the gas cylinder, and detects the weight of the gas cylinder in the real-time monitoring unit. The weight conversion system in the real-time monitoring unit converts the collected weight data into the remaining gas in the bottle, and uploads it to the MES system through the real-time monitoring unit to input the gas remaining into the material information unit.

[0006] Specifically, the real-time monitoring task is a multi-target character field sequence set according to the gas cylinder regular inspection objectives and safety facility operation implementation standards.

[0007] Specifically, the task analyzer is used to extract content from the attribute field of the real-time monitoring task, and the analysis sequence of the attribute field is set according to the data input format of the client management module.

[0008] Specifically, each of the monitored objects corresponds to a weighing sensor, the weighing sensor is initially in a closed state, and the data storage unit is used to count the address number and start / stop state information of the weighing sensor.

[0009] Specifically, the program receiving unit adopts parallel programming and implements multi-threaded operation in a single processor core through an SPMD parallel computing model.

[0010] Specifically, before starting, the real-time measurement module sends the monitoring execution time to the measurement node of the control module through the control center of the dynamic monitoring platform. The measurement node calibrates its own time according to the clock synchronization mechanism and the monitoring execution time. After the clock information of the monitoring execution time of the dynamic monitoring platform and the measurement node is synchronized, the measurement node performs collection work.

[0011] Specifically, the multi-state event-driven parallel management converts the input data of the dynamic monitoring platform into corresponding state events according to preset state events and triggers the corresponding event response mechanism for processing; the idle state is the standby process when the dynamic monitoring platform does not receive the weight measurement task generated by the program receiving unit; the parameter configuration state is the execution process of configuring, sending and processing the system parameters corresponding to the event response mechanism; the interrupt state is the execution process of scheduling the system tasks according to the command frame; the measurement state is the process from the issuance of the command frame to the receipt of the feedback signal; the data transmission state is the system communication scheduling process; and the safety detection state is the process of performing the control safety detection to obtain the detection result.

[0012] Specifically, the control safety detection method is: obtaining the ID, original weight and set gas remaining value in the gas cylinder according to the monitored object, presetting a safety deviation threshold, and detecting the gas remaining value in the detected gas cylinder corresponding to the gas cylinder ID through a special detection device. If the absolute difference between the detected gas remaining value in the gas cylinder and the set gas remaining value in the gas cylinder is less than the deviation threshold, then a normal detection result is returned, and the cylinder can continue to supply gas; if the absolute difference between the detected gas remaining value in the gas cylinder and the set gas remaining value in the gas cylinder is greater than the deviation threshold, then an abnormal detection result is returned and uploaded to the MES system. The MES system issues a command to replace the gas cylinder, and the gas cylinder cabinet switches the gas cylinder synchronously.

[0013] Specifically, in the systematic monitoring, the gas remaining value in the gas cylinder is used as the output signal of the display page, and the status output signal is intuitively displayed through four status modes: low, low-low, high, and high-high. The low mode is used to indicate that you are ready to change the cylinder, the low-low mode is used to indicate that you can start changing the cylinder, the high mode is used to indicate that the cylinder is sufficient, and the high-high mode is used to indicate that the cylinder is full.

[0014] Specifically, the systematic monitoring performs automatic control and remote monitoring by uploading the measured weight curve of the gas cylinder to the MES system, and records the weight change of the gas cylinder in the MES; when the weight measurement task is executed, the gross weight data of the gas cylinder stored in the gas cylinder information is called, and the weight data measured by the weighing sensor is subtracted from the gross weight data of the cylinder when returning to the dynamic monitoring platform to generate the weight data of the gas in the gas cylinder, and is converted into the remaining gas in the cylinder through the weight conversion system in the real-time monitoring unit.

[0015] The beneficial effects of the present invention are: Taking actual detection needs as the task goal, the weight detection sensor is dynamically started and stopped, which effectively reduces data collection time and storage resources, real-time weight collection, precise measurement and control, to ensure the stability of the production process and product quality; upload the cylinder weight curve to MES to realize automatic control and reduce damage to the valve. In the face of the problems of high latency in massive data analysis and low intelligent control of equipment, multi-state event-driven parallel management is used to meet the information integration and information-physical data fusion in the dynamic monitoring process of gas cylinders. The clock synchronization is set by the real-time measurement module to achieve the synchronization of space and physical space, providing more accurate and comprehensive data support for the integrated management of the dynamic monitoring platform. In addition, the data on the remaining gas in the gas cylinder can be viewed remotely in real time to improve production efficiency and safety. In task parallel management, by defining different states of tasks and automatically adjusting their states according to the actual progress of the tasks, resource scheduling helps manage the allocation and scheduling of system resources and ensure the rational flow and use of resources between different tasks. Risk management: record weight changes in the material information unit, track cylinders in batches and save usage records. Preset safety risk events and their corresponding processing procedures enable quick action when risks are encountered, significantly improve work efficiency, and ensure that the quality inspection process is completed on time and with quality.
