A workshop monitoring system for clutch disc production

Abstract

The present invention belongs to the technical field of workshop monitoring systems, and specifically relates to a workshop monitoring system for clutch disc production. By setting a production monitoring module, real-time video monitoring of several processes in the clutch disc production in the workshop is performed. The video control center extracts and splices the production monitoring data obtained by splicing the video monitoring data of any clutch disc based on all processes to obtain several setting sequences. Each setting sequence has several randomly selected setting arrays. In this way, randomness and complexity are added to the security conversion sequence of each setting sequence, and the length of each setting sequence is different. In this way, on the one hand, the production monitoring video of the clutch disc has high complexity and difficulty in cracking without introducing a key, thereby ensuring the security of the video. On the other hand, there is no need to use a large amount of manpower and financial resources required for key encryption, thereby reducing costs.

Description

Technical Field

[0001] The present invention belongs to the technical field of workshop monitoring systems, and in particular relates to a workshop monitoring system for clutch disc production. Background Art

[0002] As a key component in automotive transmission systems, clutch disc production quality and efficiency play a vital role in the stable operation of the entire automotive industry. The clutch disc production process involves multiple complex and sophisticated steps, including raw material preparation, machining (such as turning, milling, and drilling), heat treatment, surface treatment, and final quality inspection and assembly.

[0003] To ensure efficient and high-quality clutch disc production, it is necessary to accurately and in real time collect, monitor, and analyze key process parameters (such as processing temperature, pressure, cutting speed, etc.), equipment operating status (such as equipment start and stop, operating speed, fault alarms, etc.), production progress (processing time of each process, material flow time, etc.), and product quality-related data (such as dimensional accuracy, hardness, surface roughness, etc.).

[0004] One common method is to conduct real-time video surveillance of various processes in the clutch disc production process. By installing cameras at key locations in the production workshop, the operating status of the equipment, the operating procedures of the staff, and the processing and flow status of materials can be visually observed. Video surveillance can provide rich visual information, helping managers to promptly identify potential problems. For example, abnormal vibration of the equipment may appear as shaking equipment in the surveillance video, and illegal operations of the staff can be directly recorded.

[0005] However, there are many difficulties in the management of video surveillance data. Traditional methods usually use key encryption to protect and manage video surveillance data to prevent data leakage or illegal tampering. However, in actual applications, key encryption management requires a lot of time and financial resources. First of all, the generation, distribution, storage and update of keys require strict processes and security measures, which involves complex encryption algorithms and corresponding hardware and software facilities. For many companies, especially small and medium-sized enterprises, due to limited resources, they will not invest too much in this regard; in addition, in the process of key encryption management, since the key itself is easy to lose, once the key is lost, it may lead to the inability to access video surveillance data normally, seriously affecting the continuity of production monitoring and management work, and also bringing huge risks to data security, thereby affecting the company's production decisions, product quality traceability and safety management and other aspects. Summary of the Invention

[0006] The object of the present invention is to provide a workshop monitoring system for clutch disc production to solve the problems raised in the above background technology;

[0007] The present invention can be achieved through the following technical solutions:

[0008] A workshop monitoring system for clutch disc production, comprising:

[0009] A production monitoring module is used to monitor several processes in the clutch disc production process in real time to obtain video monitoring data of the clutch disc based on all processes;

[0010] A video control center is configured to generate production monitoring data of a clutch disc based on video monitoring data of all processes received each time;

[0011] The video control center is also used to perform security conversion on the production monitoring data of each clutch disc according to preset security conversion rules after generating the production monitoring data, to obtain the monitoring protection data of the clutch disc, and to store the monitoring protection data.

[0012] Furthermore, several processes in the clutch disc production process include blank preparation, machining, heat treatment, surface treatment and quality inspection.

[0013] Furthermore, the video control center deletes the production monitoring data of each clutch disc after storing the monitoring and protection data of the clutch disc.

[0014] Furthermore, after generating production monitoring data of a clutch disc, the video control center obtains the following security conversion rules for monitoring and protection data of the clutch disc:

[0015] S11: performing binary conversion on the production monitoring data to obtain data to be processed, and taking every four characters in the data to be processed as a set array in order from left to right to obtain a plurality of sets of set arrays;

[0018] S13: extracting and splicing from all the remaining setting arrays after the extraction according to S12 to obtain setting sequences B2, B3, ..., Bb. For example, the setting sequence B2 is to extract several setting arrays from the setting arrays Ac+1, Ac+2, ..., Aa;

[0019] S14: Randomly select P1 four-bit binary numbers from the four-bit binary numbers 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111 as an array array of the setting sequence B1, and perform decimal conversion on the selected P1 setting arrays to obtain corresponding decimal numbers, which are marked as D1, D2, ..., DP1 respectively; where P1 is a preset standard selection number;

[0020] S15: Generate a setting array of a setting sequence B1 according to the selected P1 setting arrays and a preset setting rule;

[0021] S16: performing an AND operation on the setting sequence B1 and its setting array to obtain a safe conversion sequence of the setting sequence B1;

[0022] S17: According to S13 to S16, the safe conversion sequences of the setting sequences B2, B3, ..., Bb are obtained in sequence, wherein the safe conversion sequence of the setting sequence B2 is obtained by performing an AND operation on the setting sequence B2 and its setting array, and the safe conversion sequences of the remaining setting sequences are deduced in the same way;

[0023] S18: In the order of the setting sequences B1, B2, ..., Bb, the safety conversion sequences are spliced ​​using "," to obtain the monitoring protection data of the clutch disc.

[0024] Furthermore, the extraction and splicing rules for splicing the position sequence B1 are as follows:

[0025] S121: Extract the first c bit arrays from the bit arrays A1, A2, ..., Aa in descending order of subscripts. These c bit arrays satisfy the preset extraction conditions:

[0026] At least one of these c bit arrays is the same as the four-bit binary numbers 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111, and at least one of these c bit arrays is unique among them;

[0027] S122: splicing the extracted c bit arrays in ascending order of the mark subscripts to obtain a bit sequence B1.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention performs real-time video monitoring of several processes in the production of clutch discs in a workshop by setting up a production monitoring module. The video control center securely stores the video monitoring data of the clutch disc based on each process. The production monitoring data obtained by splicing the video monitoring data of any clutch disc based on all processes is extracted and spliced ​​to obtain several setting sequences. Each setting sequence has several randomly selected setting arrays. In this way, randomness and complexity are added to the security conversion sequence of each setting sequence, and the length of each setting sequence is different. In this way, on the one hand, the production monitoring video of the clutch disc has high complexity and difficulty in cracking without introducing a key, thereby ensuring the security of the video. On the other hand, there is no need to use a large amount of manpower and financial resources required for key encryption, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS
