Description

Technical Field

[0001] The 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 the automobile transmission system, the production quality and efficiency of the clutch disc play a vital role in the stable operation of the entire automobile industry. The production process of the clutch disc involves many complex and delicate processes, including raw material preparation, mechanical processing (such as turning, milling, drilling, etc.), heat treatment, surface treatment, and final quality inspection and assembly.

[0003] In order to ensure the high efficiency and high quality of clutch disc production, it is necessary to accurately and in real time collect, monitor and analyze the key parameters of each process (such as processing temperature, pressure, cutting speed, etc.), equipment operation status (such as equipment start and stop, operation speed, fault alarm, 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 of the common methods is to conduct real-time video monitoring of various processes in the clutch disc production process. By installing cameras at various key locations in the production workshop, the operation of the equipment, the operation process of the staff, and the processing and flow status of the materials can be visually observed. Video monitoring can provide rich visual information, which helps managers to discover potential problems in a timely manner. For example, abnormal vibration of the equipment may appear as shaking of the equipment in the monitoring video, and the illegal operation of the staff can be directly recorded;

[0005] However, there are many difficulties in the management of video surveillance data. The traditional method usually uses 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 the video surveillance data normally, seriously affecting the continuity of production monitoring and management work, and also brings huge risks to data security, thus 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 implemented by the following technical solutions:

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

[0009] A production monitoring module, 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 used to generate production monitoring data of a clutch disc based on video monitoring data of all processes after receiving the video monitoring data of a clutch disc;

[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 each production monitoring data of the clutch disc is generated to obtain the monitoring protection data of the clutch disc, and 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 the clutch disc after storing the monitoring 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 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 of bit arrays in order from left to right to obtain a plurality of sets of bit arrays;

[0017] S12: extracting a number of position arrays from the position arrays A1, A2, ..., Aa according to a preset extraction and splicing rule, and splicing them to obtain a position sequence B1;

[0018] S13: extracting and splicing in sequence from all the remaining position arrays after extraction according to S12 to obtain position sequences B2, B3, ..., Bb. For example, the position sequence B2 is to extract a number of position arrays from the position 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 the 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; wherein P1 is a preset standard selection number;

[0020] S15: generating 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 sequence B1, B2, ..., Bb, the safety conversion sequence is 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 position arrays from the position arrays A1, A2, ..., Aa in descending order of the subscripts. These c position arrays satisfy the preset extraction conditions:

[0026] At least one of the 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 the c bit arrays is unique among the c bit arrays;

[0027] S122: splicing the extracted c position arrays in ascending order of the marking subscripts to obtain a position 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, and a video control center securely stores the video monitoring data of the clutch disc based on each process, wherein 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 position sequences, each position sequence having several randomly selected position arrays, and in this way, randomness and complexity are added to the security conversion sequence of each position sequence, and the length of each position sequence is different. In this way, on the one hand, the production monitoring video of the clutch disc has high complexity and difficulty to crack without introducing a key, thereby ensuring the security of the video, and 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.
