[0040] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Ditch covers are located in outdoor environments and are often subject to weather changes. The performance of the main materials of the trench covers is easily weakened. In addition, the production efficiency is also affected by insufficient process control.

[0042] The technical solution of the implementation mode of the present application solves the problems of unstable material properties and low production efficiency in the prior art by providing a trench cover. The beneficial effects of stabilizing material properties and improving production efficiency are achieved by combining volcanic ash rock powder with urban solid waste and industrial solid waste to crush into granular filler and using a reinforcing structure 200 composed of composite reinforcing ribs 300 and adopting an intelligent management system for power product production based on full-process production tracking in the production process.

[0043] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0044] A trench cover is composed of a concrete body 100 and a reinforcement structure 200 nested in the concrete body. The concrete body is made of raw materials including cement, volcanic ash rock powder, ceramic fiber and filler, the filler comes from particles crushed from urban solid waste and industrial solid waste, and is combined with a reinforcement structure composed of composite fiber 500 reinforcement ribs. An intelligent management system for power product production that tracks the entire production process is used during the production process.

[0045] The material properties of volcanic ash are fully utilized, and the fillers made of crushed urban solid waste and industrial solid waste are combined with ceramic fibers to strengthen the material properties of the main part, and the material properties of the trench cover are further strengthened through the reinforcement structure composed of composite glass fiber reinforcement ribs. At the same time, the intelligent management system for power product production based on full production process tracking is used to comprehensively analyze the preheating start time and the time of each production, comprehensively analyze the production efficiency of the production line, and remove the interference of the actual external factors affecting the collection time and the start-up production time on the judgment of production efficiency, accurately judge whether the production line efficiency is compliant, and alarm the production line that does not meet the requirements to prompt the relevant staff to carry out maintenance as soon as possible.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] One embodiment of the present invention provides a trench cover, such as Figure 1 and Figure 2 As shown, it consists of a concrete body and a reinforcement structure nested in the concrete body; the concrete body is made of raw materials including cement, volcanic ash rock powder, ceramic fiber and filler, and the reinforcement structure is composed of composite glass fiber reinforcement; the filler comes from particles crushed from urban solid waste and industrial solid waste; the production process of the trench cover adopts an intelligent management system for power product production based on full production process tracking.

[0048] Specifically, the raw materials of the concrete body also include graphene oxide, silica fume, aggregates and coral powder; the aggregates come from at least one of recycled concrete or recycled bricks, which reduces resource waste and improves the environmental friendliness of the product. In addition, the coral powder is preferably powder ground from finger-shaped corals to further improve the material performance.

[0049] Specifically, the volcanic ash rock powder is preferably selected from rocks of extinct volcanoes in Enping, Guangdong as raw materials.

[0050] More specifically, the raw materials of the concrete body also include biocalcium particles; the composite fiber 500 is composed of glass fiber, carbon fiber and basalt fiber. The biocalcium particles improve the material properties of the concrete, and the material strength of the concrete is further enhanced by combining the glass fiber, carbon fiber and basalt fiber. The biocalcium particles are preferably selected from oyster shells.

[0051] Specifically, the reinforcement structure is composed of inner reinforcement ribs 210, outer ring reinforcement ribs 220 and steel bars 400 wrapped by the inner reinforcement ribs 210 and the outer ring reinforcement ribs 220; the inner reinforcement ribs 210 and the outer ring reinforcement ribs 220 are composed of composite fibers 500, and the composite fibers 500 are fibers composited from glass fibers, carbon fibers and basalt fibers.

[0052] The steel bars 400 of the reinforcing structure, the composite glass fiber reinforcing bars and the steel bars 400 together constitute a reinforcing structure; concrete is poured in the reinforcing structure.

[0053] The ratio of the raw materials can be adjusted according to the experience in the art. The size of the fibers used in the reinforced structure 200 and the concrete body 100 can also be adjusted according to the experience in the art.

[0054] The material properties of the volcanic ash are fully utilized and superimposed on the filler made of crushed urban solid waste into particles, so as to strengthen the material properties of the main part, and further strengthen the material properties of the trench cover through the reinforcement structure 200 composed of composite glass fiber reinforcement ribs 300. The material properties of the product are strengthened through both materials and structures.

[0055] The embodiments of the present invention also provide an intelligent management system for the production of power products based on full-process tracking of production. The production efficiency of the product production line is determined by comprehensively considering the pre-start time of each production line and the production time of a single product. The production efficiency of the production line is further corrected in combination with the environment and communication status of each production line to ensure that the production efficiency status of each production line is obtained in a timely and accurate manner, so as to enable timely early warning and regulation of problem production lines.

[0056] The invention provides an intelligent management system for electric power product production based on full production process tracking, including the following application examples:

[0057] Example 1

[0058] Figure 3 A schematic diagram of an intelligent management system for power product production based on full-process production tracking of the present invention is given, which specifically includes a main control module, a production line combing module, a production line analysis module, a data correction module and an early warning and control module.

[0059] The main control module is connected to the production line combing module by signal, and is used to issue control instructions to the production line combing module, that is, to send data collection instructions to the production line combing module, so as to collect data and monitor the entire production line.

[0060] The production line combing module numbers each production line i in the production intelligent management system in sequence, where i is a positive integer, i=1, 2, ... n. After receiving the data collection instruction sent by the main control module, the production line combing module collects and obtains the production time information of each production line, and sends the production time information to the production line analysis module for production efficiency analysis of each production line.

[0061] The production duration information includes the preheating start-up duration of each production line and the single-round production duration. The preheating start-up duration refers to the preheating stage required before each production line is put into operation. The purpose of preheating is to ensure that the equipment, machines and systems are at the appropriate temperature to ensure the smooth progress of the production process. Different production lines often have different preheating times due to their respective equipment differences. The longer the preheating time, the lower the production efficiency of the production line. The single-round production duration refers to the average production time used by the production line to produce a batch of power products. Obviously, the larger the single-round production duration, the lower the production efficiency.

[0062] After the production line analysis module receives the production time information sent by the production line combing module, it comprehensively considers the preheating start time value and the single-round production time value to determine the production efficiency of each production line. Specifically, since the production efficiency of the production line is mainly determined by the preheating time and the production time used to produce a batch of power products, when the batch quantity of the produced products is different, the proportion of the two in production is also different, that is, their respective weights are different. Therefore, the production line analysis module obtains the production efficiency evaluation coefficient Ei of each production line through calculation. The specific calculation expression is as follows:

[0063]

[0064] In the formula, α 1 , α 2 are the preset proportional coefficients of the preheating start time value and the single round production time value, t 预 i is the preheating start-up duration of the i-th production line, t 轮 i is the single-round production duration of the i-th production line, and m is the total production rounds of the i-th production line.

[0065] In an alternative example, for α1 , α 2 When the total production time is shorter and the batches of power products produced by the machine are smaller, the preheating start time value has a greater impact on production efficiency. 1 Increases accordingly, on the contrary, α 1 It is getting smaller and smaller.

[0066] That is, the preset ratio of the preheating start time value to the single-round production time value is determined according to the ratio of the preheating start time value to the total production time.

[0067] The present invention can more accurately analyze the production efficiency status of each production line by comprehensively analyzing the preheating start-up time of the production line and the time used for each batch of production.

[0068] Specifically, the production line analysis module compares the production efficiency evaluation coefficient Ei of each production line with the standard efficiency threshold to evaluate whether the production efficiency of each production line meets the requirements.

[0069] If the production efficiency evaluation coefficient Ei of each production line is greater than or equal to the standard efficiency threshold, it means that the production efficiency of the production line does not meet the requirements and the overall time is too long. At this time, the production line analysis module will mark the production line as a primary slow production line and send the production line information to the data correction module for further analysis and determination of the production line.

[0070] If the production efficiency evaluation coefficient Ei of each production line is less than the standard efficiency threshold, it means that the production efficiency of the production line is within the expected requirements. At this time, there is no need to issue an alarm for the production line, and the production line is a normal efficiency production line.

[0071] It should be noted that since the single-round production duration value is the average production time used by the production line to produce a batch of power products, each additional production cycle will have a greater impact on production efficiency, and the single-round production duration value collected in real time will also be different.

[0072] The data correction module is used to perform a secondary check on the primary slow production line marked by the production line analysis module to determine the cause of the low efficiency of the monitored production line.

[0073] Specifically, after the data correction module receives the primary slow production line sent by the production line analysis module, it sends a fluctuation information query signal to the production line combing module. The production line combing module separately collects the fluctuation information of the primary slow production line and sends it to the data correction module.

[0074] Fluctuation information includes production line environment information and data transmission information. Production line environment information refers to the environment information near the primary slow production line, including temperature and humidity values. Different temperatures and humidity in the production line environment will affect the preheating time of the production line. Data transmission information refers to the data transmission delay value. The greater the deviation between the data transmission delay and the standard delay, the less accurate the collected time. The data collection speed is slower than the system processing speed, resulting in data accumulation, which affects the overall time accuracy of the system. If the data collection speed is too fast, the system may not be able to process the data correctly, which will affect the time accuracy. Therefore, the greater the deviation between the data delay and the standard delay, the worse the time accuracy of the collection, and the monitoring results of the production line preheating time and production time will be correspondingly larger.

[0075] Therefore, the data correction module further analyzes the accuracy of the primary slow production line based on the production line environment information and data transmission information, that is, it performs calculation analysis based on the actual production line environment and data transmission status. The specific calculation expression is as follows:

[0076]

[0077] Where, T 温 i is the temperature data near the ith production line, T 0 i is the standard temperature data near the ith production line, Rh 温 i is the humidity data near the ith production line, Rh 0 i is the standard humidity data near the i-th production line, Bit 延 i is the data transmission delay value of the i-th production line, Bit 0 i is the standard data transmission delay value of the i-th production line; β 1 , β 2 , β 3 They are respectively the temperature value, humidity value and data transmission delay value and the preset proportional coefficient. i An accurate assessment factor for primary slow production lines.

[0078] It should be noted that in the above formula, data correction is not performed on all production lines. Only the production line environment information and data transmission information of the primary slow production line are collected and corrected accordingly, which greatly shortens the data processing volume and enables targeted secondary confirmation of the production lines with poor efficiency.

[0079] The data correction module sets the standard accuracy threshold as δ 0 , will accurately evaluate the coefficient δ i Compared with the standard accurate threshold δ0 Compare and determine the exact situation of the primary slow production line.

[0080] If the coefficient δ is accurately estimated i Greater than or equal to the standard accuracy threshold δ 0 , it means that the primary slow production line is subject to large external fluctuation factors. At this time, the data correction module sends the calculation expression of the accurate evaluation coefficient to the early warning and control module. The early warning and control module issues corresponding early warnings based on the deviation status of the production line environment information and the data transmission information. For example, when the influence of the temperature item is too large, a temperature alarm is issued.

[0081] On the contrary, if the coefficient δ is accurately evaluated i Less than the standard accuracy threshold δ 0 , no warning is given.

[0082] Furthermore, the data correction module calculates the accuracy evaluation coefficient δ i Compared with the standard accurate threshold δ 0 ratio, and set this value as δ i * , through formula E i * =E i / δ i * , calculate the corrected production efficiency evaluation coefficient E i * , and then the corrected production efficiency evaluation coefficient E i * Compare with the standard efficiency threshold to evaluate whether the production efficiency of each production line meets the requirements.

[0083] If the corrected production efficiency evaluation coefficient E i * If it is greater than or equal to the standard efficiency threshold, it means that the production efficiency of the production line still does not meet the requirements and the overall time is too long. At this time, the data correction module will mark the production line as an inefficient production line and send the production line information to the early warning and control module. The early warning and control module will issue an alarm prompt to the production line.

[0084] If the corrected production efficiency evaluation coefficient E i * If it is less than the standard efficiency threshold, it means that the actual production efficiency of the production line is within the expected requirements after removing external influences. At this time, the data correction module marks the production line as a normal efficiency production line, and there is no need to issue an alarm for the production line.

[0085] The present invention comprehensively analyzes the preheating start time and the time of each production, comprehensively analyzes the production efficiency of the production line, and removes the interference of actual external factors on the collection time and the start of production time on the judgment of production efficiency, accurately judges whether the production line efficiency is compliant, and alarms the production lines that do not meet the requirements, so as to prompt relevant staff to carry out maintenance as soon as possible.

[0086] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
