[0064] Specifically, the embodiment of the present invention can efficiently collect real-time equipment data by setting the data acquisition module to accurately divide the workshop production structure into actual production areas and determine the target production area and target production equipment, thereby improving the accuracy and pertinence of data acquisition, reducing unnecessary data redundancy, and providing a reliable basis for subsequent data analysis. By setting the area allocation module to determine the area relevance and priority, and reasonably allocating the total transmission channel, the efficiency and stability of data transmission are ensured, which helps to optimize resource utilization, reduce transmission delays, and improve the overall performance of the system. By setting the equipment allocation module, accurate matching of resources at the equipment level is achieved, ensuring that the operating data of key equipment can be transmitted and processed in a timely and accurate manner, so as to timely discover equipment. Abnormalities and taking corresponding measures can ensure the stable operation of equipment, reduce the impact of equipment failures on production, and improve the safety of the production process. By setting up the data analysis module, the timeliness and accuracy of equipment maintenance are improved, and the intelligent dynamic adjustment of data acquisition and transmission resources is realized, so that the data transmission efficiency is always matched with the actual operation requirements of the equipment, the data processing and transmission efficiency of the entire system is improved, and the resource utilization efficiency is optimized. By setting up the regional analysis module, the abnormal production status can be quickly grasped from the overall regional level, ensuring that the data in the abnormal area can be transmitted in time, avoiding the backlog of data in the abnormal area due to insufficient resources, and quickly responding to problems in the production process by setting the alarm module to prevent the problem from expanding, ensuring production safety, and improving the timeliness of abnormal situation judgment in the workshop.

[0065] See also Figure 2 As shown, the data acquisition module 10 includes:

[0066] A division unit 11 is used to determine the equipment layout in the workshop and the material flow path corresponding to the target production task, and divide the workshop into several actual production areas based on the equipment layout and the material flow path;

[0067] A target determination unit 12, connected to the division unit 11, is used to determine a number of preset production equipment required in the target production task, match the number of preset production equipment with a number of actual production equipment to obtain target production equipment, and determine a target production area based on the number of target production equipment;

[0068] The acquisition unit 13 is connected to the target determination unit 12, and is used to set a plurality of vibration sensors and a plurality of temperature sensors on a plurality of production equipment corresponding to any of the actual production areas, so as to acquire a plurality of real-time vibration values ​​and a plurality of real-time temperature values ​​in real time based on a preset frequency;

[0069] The data integration unit 14 is connected to the acquisition unit 13 and is used to integrate the real-time vibration values, the real-time temperature values, their corresponding production equipment and actual production areas in a one-to-one correspondence.

[0070] Specifically, the embodiment of the present invention divides the equipment layout and material flow path in the workshop by setting the division unit so that the division result closely fits the actual production situation and specific production task requirements of the workshop, clarifies the functions and production priorities of different areas, avoids blindly collecting irrelevant data, improves data collection efficiency and the relevance of data to actual production, and ensures the pertinence and accuracy of data collection by setting the target determination unit, avoids unnecessary data redundancy, helps to further narrow the scope of data collection, and improves the efficiency of data collection. By setting the collection unit, the data of equipment operation is obtained from multiple dimensions, the actual operating status of the equipment is fully and timely grasped, and the reliable operation of the equipment is guaranteed. By setting the data integration unit, the data is made clearer and easier to understand, which is helpful for subsequent data analysis and processing and improves the efficiency of subsequent data processing.

[0071] It can be understood that the embodiment of the present invention includes an area corresponding to any target production equipment as a target production area.

[0072] It can be understood that the preset frequency in the embodiment of the present invention is 1 hour / time.

[0073] It can be understood that the preset production equipment described in the embodiment of the present invention is to determine several historical equipment used in the process of the target production task based on historical data, and then determine the total equipment type of several historical equipment, and determine the total historical quantity corresponding to several historical equipment as the total equipment quantity.

[0074] It is understandable that the division unit of the embodiment of the present invention divides the workshop into several sub-target production areas according to the equipment layout and material flow path in the workshop. First, the physical location of all production equipment in the workshop is mapped and marked in detail, an accurate equipment layout diagram is constructed, and the upstream and downstream relationships between the equipment in the production process are analyzed, that is, which equipment output is directly used as the input of the subsequent equipment, and the material flow order and path between the equipment are determined. For example, in a refrigeration equipment production line, the finished product of the compressor production equipment will be directly delivered to the condenser assembly equipment, so the two equipments are closely connected in material flow. Then, according to the key nodes and path directions of these material flows, a group of equipment that are closely related to each other along the same path is divided into the same sub-target production area. For some equipment groups with relatively independent functions and self-contained material flow, they are also divided into a sub-area separately. For example, a separate test equipment area mainly performs performance testing on finished refrigeration equipment, and has a relatively low correlation with the material flow of the production line, and can be divided separately.

[0082] It can be understood that the regional priority determination unit in the embodiment of the present invention calculates the priority score based on the type proportion and the quantity proportion, priority score = type proportion + quantity proportion, and determines the regional priority based on the descending order of the priority scores.

Each link has its specific process requirements and operating specifications. Taking compressor production as an example, the compressor casing produced by the casing casting equipment is used as the input material of subsequent equipment such as rotor processing equipment and motor assembly equipment, and the flow order and matching relationship of these materials between the various equipment are determined at the same time, such as one casing corresponds to a specific model and quantity of rotor and motor components.
