- the adaptive water control method of this mixing station can include the following steps:
- Step S100 Obtain the change rate of moisture content of the material.
- the moisture content change rate is a dynamic value used to represent the moisture content change trend of the materials on different trays in the current batch, which can be represented by V. .
- V. The moisture content change rate of moisture content
- the change rate of moisture content can make the staff more suitable for the current batch of raw materials when selecting the ratio of aggregate and water and the ratio adjustment method, thus improving the accuracy and flexibility of water control.
- Step S200 Based on the moisture content change rate of the material and the preset proportioning target value of the current batch of materials, determine the measurement mode and actual proportion of the current batch of materials.
- the material in the current batch is the material in the aggregate tray currently on the conveyor belt;
- the preset ratio target value refers to the required standard ratio of aggregate and water before starting production, that is, the ideal ratio of aggregate and water.
- the measurement mode refers to the mode preset by the system for material measurement. According to the different moisture content changes of the material, different measurement modes are set, such as single measurement, two measurement or multiple measurement, etc., so that it can be more accurate Measure materials in a targeted manner to reduce The influence of different moisture content of materials on weighing materials.
- the actual ratio is the final usage ratio of aggregate and water in the material, that is, the final proportion of aggregate and water usage taking into account the moisture content of the aggregate.
- Step S300 Measure the current batch of materials based on the measurement mode and actual proportion.
- the metering mode and actual ratio are set taking into account the moisture content of the current batch of aggregates and the change rate of moisture content, this makes the measurement of aggregates and water more reliable, thereby making the final actual ratio of aggregates and water Closer to the preset target ratio or standard ratio.
- the above proportion adjustment can be directly applied to the current batch of materials, which alleviates the problem of water control hysteresis. At the same time, it improves the water control accuracy of the mixing station, improves production quality, and causes less loss of detection devices, etc., reducing maintenance costs. .
- the adaptive water control method of the mixing station specifically includes the following steps: obtaining the moisture content change rate of the material; based on the moisture content change rate of the material and the preset ratio target value of the current batch of materials , determine the measurement mode and actual proportion of the current batch of materials; based on the measurement mode and actual proportion, perform the measurement of the current batch of materials.
- the adaptive water control method of this mixing station combines the parameter of aggregate moisture content change rate when setting the measurement mode of aggregate and water and obtaining the final actual ratio, making the ratio of aggregate and water closer
- the standard proportion required for production, and the water control process adapts to the water content characteristics of the current batch of materials, forming a better control method that automatically adjusts the proportion of aggregate and water, and the control process does not require manual participation, while improving production efficiency. At the same time, it effectively ensures the reliability and accuracy of the water control process of the mixing station and reduces the occurrence of production quality problems.
- FIG. 2 shows a schematic flow chart of the metering mode and the actual proportion determination method in the adaptive water control method of the mixing station provided by another embodiment of the present application.
- the processing methods of step S200 and step S300 are different. Among them, when the moisture content change rate is small, step S200 (based on the moisture content change rate of the material and the preset proportioning target value of the current batch of materials, determine the measurement mode and actual proportion of the current batch of materials) May include the following steps:
- Step S210 When the change rate of the moisture content of the material is less than or equal to the first preset threshold, determine the proportion of the material in the current batch based on the preset ratio target value of the material in the current batch and the moisture content of the material in the previous batch. Actual proportioning, and determine the measurement mode of the current batch of materials as single measurement mode.
- the first preset threshold is a threshold preset by the system or staff based on actual production conditions. It can be used as a basis for judging the proximity of the current batch of aggregate moisture content. For example, it can be set to 0.5, 1 or 1.5, etc.
- the specific value should be determined according to the actual production situation. It depends on the specific application scenario.
- the single weighing mode means that the materials can be weighed only once, that is, the aggregate and water are weighed in a single time, and this weighing is used as the final ratio of the materials. Taking the case where the first preset threshold is 1 as an example, when V ⁇ 1, it means that the moisture content of the aggregates in different batches of the current batch is not much different, and the moisture content value of the previous batch of materials is used as the current batch of materials.
- the moisture content reference parameter is reliable and effective. In order to improve production efficiency, it is feasible to calculate the moisture content of the aggregate of the current batch of materials based on the moisture content detection data of the previous batch of materials. Therefore, in this case, it is necessary to detect the moisture content detection data of the previous tray of materials and aggregates, and use this to calculate the moisture content of the previous tray of materials and aggregates, as a reference for the actual proportion of materials in the current tray.
- the weight of the current material aggregate can be calculated according to the following formula 1:
- Ti represents the current usage quality of the i-th type of aggregate
- k represents the current tray volume of the i-th type of aggregate (the current tray volume k can be calculated from the aggregate usage in the preset ratio target value)
- ui represents the moisture content of the i-th aggregate
- Ri represents the dehydration quality of the i-th aggregate under each production volume. It should be understood that according to the above description, ui here adopts the aggregate moisture content of the i-th aggregate in the previous plate of materials.
- n the number of aggregate types in the current plate.
- the system will substitute the corresponding parameters into the above formula 1 and formula 2 to calculate the amount of aggregate and water, etc., thus Get it when The predicted proportion of aggregate and water in the front plate material.
- the predicted proportion calculated in this way is more in line with the current moisture content of the aggregate, and it is more convenient and time-saving to use the aggregate moisture content parameter.
- step S200 based on the moisture content change rate of the material and the preset ratio target value of the current batch of material, determine the measurement mode and actual ratio of the current batch of material Proportion
- step S300 measurement of the current batch of materials based on the measurement mode and actual proportion
- Step S220 When the change rate of the moisture content of the aggregate is greater than the first preset threshold, determine that the water metering mode of the current batch is the secondary metering mode.
- the secondary measurement mode means that the material is measured twice, including the first measurement and the second measurement. The total of the two measurements is the final usage of the material.
- the change rate of moisture content is greater than the first preset threshold, it means that there is a certain difference in the moisture content of the current batch of aggregates, that is, the amount of water is greatly affected by the moisture content of the aggregates, and the aggregates of the previous batch cannot be The moisture content is directly applied to the current plate. At this time, it is more reliable and accurate to use the secondary measurement mode for water, so that the amount of water can be adjusted accordingly during the secondary measurement of water.
- Step S221 Based on the preset ratio target value and the first preset ratio of the current batch of materials, determine the first measurement value of the current batch of water, and calculate the current batch of water based on the first measurement value of the current batch of water. Water is metered for the first time.
- the first measurement value is the usage value of the material in the first measurement when executing the secondary measurement mode.
- the first preset ratio is a value preset by the system.
- the specific value can be preset according to production needs. For example, it can be set to 70%-90%. This is not further limited here. Taking the first preset ratio as 70% as an example, the first measurement value of water may be 70% of the preset target ratio value.
- Step S222 Based on the moisture content of the aggregate in the current batch and the preset ratio target value, determine the actual proportion of water in the current batch, based on the actual proportion of water in the current batch and the first time of the water in the current batch The measurement value determines the secondary measurement value of the water in the current tray, and the water in the current tray is measured twice based on the secondary measurement value of the water in the current tray.
- the secondary measurement value refers to the value of the second measurement of the material based on the moisture content of the aggregate in the current batch after the first weighing of the material. It can also be understood as adjusting the final actual mixture of aggregate and water. During the ratio, the mass of water added twice is used to make the actual ratio closer to the preset ratio target value. Since the change rate of moisture content in step S220 is greater than 1, it means that the moisture content of the current batch of aggregates has a certain change, and the degree of similarity is not high. Therefore, during the production process, the uncertainty of the water content in the aggregate increases, and it is impossible to determine the moisture content of the current batch of aggregates with reference to the moisture content of the previous batch of aggregates.
- Adjustment space for secondary metering of water is a more effective way to control water. Reducing the amount of water can make it possible to promptly adjust the ratio of aggregate to water in the current tray of materials after the aggregate moisture content of the current tray of materials is determined, making it closer to the standard ratio of aggregate to water and ensuring production quality.
- the system can calculate the moisture content of the aggregate in the current plate, and then calculate the quality of water in the aggregate.
- the system can calculate the current plate It is accurate and feasible to use this difference as the secondary measurement value of water based on the difference between the amount of reclaimed water and the amount of water used in the standard proportion.
- the corresponding weighing water is added to the current batch of materials, that is, the final actual ratio of the materials is determined, and then production can continue according to the production process, so that the actual ratio of aggregate and water The ratio is closer to the standard ratio, which improves production quality.
- the measurement mode of the aggregate should be further determined based on the size of the moisture content change rate. The following will be the case where the moisture content change rate is between the first preset threshold and the first preset threshold. Situations between two preset thresholds are presented.
- step S200 (based on the preset ratio target value of the current batch of materials) and the first preset ratio, determine the first measurement value of water, and perform the first measurement of the current batch of water based on the first measurement value of water) and step S300 (based on the measurement mode and the actual proportion, perform the first measurement of the current batch of materials) Measurement) may include the following steps:
- Step S230 When the change rate of the moisture content of the aggregate is greater than the first preset threshold and less than or equal to the second preset threshold, determine that the measurement mode of the current batch of aggregate is the single measurement mode.
- the second preset threshold is the same as the first preset threshold, which can be used as a basis for judging that the moisture content of the current batch of aggregates does not converge but the degree of difference is controllable.
- the following takes the second preset threshold as 2 as an example. That is, when 1 ⁇ V ⁇ 2, it is still necessary to obtain the moisture content detection data of the previous plate of material, but the subsequent processing steps are different.
- Step S231 Determine the actual proportion of the aggregate in the current batch based on the preset ratio target value of the materials in the current batch and the moisture content of the aggregate in the previous batch.
- the amount of aggregate in the current plate can be calculated.
- the actual proportion of aggregate calculated in this way is more in line with the current moisture content of the aggregate, and it is more convenient and time-saving to use the aggregate moisture content parameter.
- Step S232 Measure the aggregate of the current batch based on the single measurement mode and the actual proportion of the aggregate of the current batch.
- the change rate of moisture content is between 1 and 2, indicating that the moisture content of the current batch of aggregates has certain changes, but the difference is still within a controllable range.
- the amount of aggregate used is often much greater than the amount of water, so it is more reasonable and efficient to use single measurement mode to measure aggregates at this time.
- step S200 when the moisture content change rate is greater than the second preset threshold, step S200 (based on the preset ratio target value and the first preset ratio of the current batch of materials , determine the first measurement value of water, and measure the current batch of water for the first time based on the first measurement value of the current batch of water) and step S300 (based on the measurement mode and actual proportion, measure the current batch of materials) It can also include the following steps:
- Step S240 When the change rate of the moisture content of the aggregate is greater than the second preset threshold, determine that the measurement mode of the current batch of aggregate is the secondary measurement mode, and the second preset threshold is greater than the first preset threshold.
- the second preset threshold value of 2 is used as an example.
- V>2 it means that the aggregate moisture content of the current batch is significantly different.
- the aggregate moisture content of the previous batch of materials is different from the aggregate moisture content of the current batch of materials.
- the moisture content reference is of little significance.
- the aggregate should also adopt the secondary measurement mode, that is, reduce the amount of aggregate and water according to a certain proportion, and use it as The predicted proportion of the first weighing is more reliable and effective for subsequent adjustment of the proportion of aggregate and water, that is, the secondary measurement mode is used for both aggregate and water.
- Step S241 Determine the first measurement value of the aggregate in the current batch based on the preset ratio target value and the second preset ratio of the materials in the current batch, and calculate the first measurement value of the aggregate in the current batch based on the first measurement value of the aggregate in the current batch.
- the aggregates are measured for the first time.
- the second preset ratio is the same as the first preset ratio, and is only the ratio used for the first measurement of aggregate or water in different modes. It should be noted that the first preset ratio and the second preset ratio may be equal or different, and the specific values shall depend on the specific application scenario.
- Step S242 Determine the secondary measurement value of the aggregate in the current batch based on the actual proportion of the aggregate in the current batch and the first measurement value of the aggregate in the current batch, and determine the secondary measurement value of the aggregate in the current batch based on the second measurement value of the aggregate in the current batch. The value is used to measure the aggregate of the current batch twice.
- the aggregate measured for the first time is the measurement of reduction. Therefore, after obtaining the aggregate moisture content of the current plate material, it is substituted into the preset formula to calculate the adjustment of the aggregate.
- Quantity that is, the secondary measurement quality of aggregate.
- the second preset threshold is greater than the first preset threshold, when the moisture content is greater than the second preset threshold, it must be greater than the first preset threshold.
- the water in the current dish should also be in the secondary metering mode, that is, the aggregate and water in the current dish both adopt the secondary metering mode, and the water in the current dish should be in the second metering mode.
- the measurement and secondary measurement process can refer to the above steps, which will not be described in detail here.
- the step "based on the moisture content and preset ratio of the aggregate in the current batch” in step S222 "Target value, determine the actual proportion of water in the current batch” may include: based on the moisture content of the aggregate in the current batch and the preset ratio target value, determine the actual proportion of aggregate in the current batch and the actual proportion of water. Proportioning, that is to say, the actual proportion of aggregates in the current batch and the actual proportion of water in the current batch are determined based on the moisture content of the aggregate in the current batch and the preset ratio target value.

If you need to calculate the change rate of material moisture content in the 11th tray, use the moisture content of trays 1-10 respectively. After receiving the test data, calculate the moisture content respectively, and calculate the 11th tray based on the moisture content of these 10 trays.
- the change rate of moisture content of secondary materials are the production trays pre-selected by the system to calculate the moisture content change rate of materials in different production trays.
- the number of multiple trays may be 5 consecutive trays, 10 trays or 15 trays, etc., preferably 10 trays. If you need to calculate the change rate of material moisture content in the 11th tray, use the moisture content of trays 1-10 respectively. After receiving the test data, calculate the moisture content respectively, and calculate the 11th tray based on the moisture content of these 10 trays
- Step S120 Based on the moisture content of the materials in multiple trays, obtain the change rate of the moisture content of the material.
- the moisture content of the material calculated in step S110 is used to calculate the moisture content change rate V. In this way, the change of the aggregate moisture content of the current batch can be intuitively determined, thereby determining how to set the actual production tray outside the preset tray. Proportion.

The loading speed at which the aggregate is loaded onto the conveyor production tray at this time.
- the unloading speed acquisition and aggregate thickness acquisition in this step are intermittent acquisition processes, that is, the system can preset time intervals and acquire these two unloading parameters regularly.
- Step S402 When the unloading speed of the current batch of materials is greater than or equal to the preset speed threshold, detect the moisture content of the current batch of materials.
- the preset speed threshold is the critical threshold preset in the system to determine whether the current discharge speed is normal. That is, when the discharge speed is less than this threshold, it means that the aggregate discharge speed is too slow and there may be abnormalities, such as sand agglomeration. If production or moisture content testing is started at this time, invalid data may easily be generated. Monitoring should be started only after the abnormal problems are resolved.

Moisture content.
- the thickness of the material refers to the thickness of the aggregate laid flat on the conveyor belt.

When the current thickness of the aggregate is small, it also indicates that the discharge is abnormal. At this time, it is still extremely difficult to obtain data. It is possible to obtain invalid data.

图1所示为本申请一实施例提供的搅拌站的自适应控水方法的流程示意图。如图1所示,此搅拌站的自适应控水方法可以包括如下步骤:
步骤S100:获取物料的含水率变化率。
物料可指任一生产盘中的同种或不同种骨料与水,含水率变化率为一动态数值,用以表示当前批次不同盘上的物料的含水率变化趋势,可以用V来表示。当含水率变化率较大时,说明此批次的骨料含水率情况不稳定,不同盘间的骨料含水率差异较大;当含水率变化率较小时,说明此批次的骨料含水率稳定,不同盘上的骨料含水率接近。参考含水率变化率可以使得工作人员在选择骨料和水的使用配比以及配比调整方式时,更加适配当前批次原料的情况,从而提高控水的准确性和灵活性。
步骤S200:基于物料的含水率变化率和当前盘次的物料的预设配比目标值,确定当前盘次的物料的计量模式和实际配比。
当前盘次的物料即为当前处于输送皮带上的骨料盘中的物料;预设配比目标值指启动生产前骨料与水的所需标准配比,即理想状态下的骨料与水配比值;计量模式指***预设的用于进行物料计量的模式,针对物料的不同含水率变化情况,设置不同计量模式,如单次计量、两次计量或多次计量等,如此可以更有针对性地对物料进行计量,降低物
料含水率不同对称量物料造成的影响。实际配比为物料中骨料与水的最终使用比例,即在考虑到骨料含水率的情况下,最终确定的骨料与水的用量比例。
步骤S300:基于计量模式和实际配比,进行当前盘次的物料的计量。
由于计量模式与实际配比均为考虑了当前批次骨料的含水率以及含水率变化率设定的,如此使得骨料与水的计量更加可靠,进而使得骨料与水的最终实际配比更加接近预设目标配比或标准配比。上述配比调整可以直接应用于当前盘物料,缓解了控水滞后性的问题,同时提高了搅拌站的控水准确性,提高生产质量,且对于检测装置等的损耗较小,降低了维护成本。
本申请提供的这种搅拌站的自适应控水方法,具体包括如下步骤:获取物料的含水率变化率;基于所述物料的含水率变化率和当前盘次的物料的预设配比目标值,确定当前盘次的物料的计量模式和实际配比;基于计量模式和实际配比,进行当前盘次的物料的计量。此搅拌站的自适应控水方法在设置骨料与水的计量模式以及获取最终的实际配比时,均结合了骨料含水率变化率这一参数,使得骨料与水的配比更加接近生产所需标准配比,且控水过程自适应当前批次物料的含水特性,形成了自动调整骨料和水配比的更优控制方式,且控制过程无需人工手动参与,在提高生产效率的同时,有效保证了搅拌站控水过程的可靠性和准确性,减少了生产质量问题的出现。
在一种可能的实现方式中,图2所示为本申请另一实施例提供的搅拌站的自适应控水方法中计量模式和实际配比确定方法的流程示意图。如图2所示,考虑到骨料的含水率变化率的大小不同,步骤S200和步骤S300的处理方式不同。其中,当含水率变化率较小时,步骤S200(基于所述物料的含水率变化率和当前盘次的物料的预设配比目标值,确定当前盘次的物料的计量模式和实际配比)可以包括如下步骤:
步骤S210:在物料的含水率变化率小于或等于第一预设阈值时,基于当前盘次的物料的预设配比目标值和上一盘次的物料的含水率确定当前盘次的物料的实际配比,并确定当前盘次的物料的计量模式为单次计量模式。
第一预设阈值为***或工作人员根据实际生产情况所预先设置的阈值,其可以作为当前批次骨料含水率接近的判断依据,如可以设置为0.5、1或1.5等,具体数值应视具体的应用场景而定。单次计量模式指物料可以只进行一次称量,即单次称量骨料与水,并以该次称量作为物料的最终配比。以第一预设阈值为1的情况举例,当V≤1时,说明当前批次不同盘次上的骨料含水率相差不大,以上一盘次物料的含水率值来作为当前盘次物料的含水率参考参数是可靠且有效的,为提高生产效率,基于上一盘次物料的含水率检测数据来计算当前盘物料骨料的含水率是可行的。因此,此种情况下需要检测上一盘物料骨料的含水率检测数据,并以此计算出上一盘物料骨料的含水率,作为当前盘次物料实际配比的参考。
具体可以根据下列公式一来进行当前盘物料骨料的使用重量的计算:
其中,Ti表示第i种骨料的当前盘次使用质量;k表示第i种骨料的当盘方量(预设配比目标值中的骨料用量即可计算出当盘方量k);ui表示第i种骨料的含水率,Ri表示每一生产方量下,第i种骨料的脱水质量。应当理解,根据上文描述,此处的ui采用的是上一盘物料中的第i种骨料的骨料含水率。
根据下列公式二来进行当前盘物料水的使用重量的计算:
其中,n表示当盘的骨料种类数。
结合当前盘物料的骨料与水的预设配比目标值以及上一盘物料的含水率,***将对应参数代入上述公式一以及公式二即可计算出骨料用量以及水的用量等,从而获取到当
前盘物料的骨料与水的预测配比。通过这种方式计算出的预测配比更加符合骨料的含水率现状,使用骨料含水率参数时更加便捷省时。
在另一种可能的实现方式中,如图2所示,下面将以物料包括骨料和水对本申请提供的自适应控水方法进行说明。其中,当含水率变化率大于第一预设阈值时,步骤S200(基于物料的含水率变化率和当前盘次的物料的预设配比目标值,确定当前盘次的物料的计量模式和实际配比)和步骤S300(基于计量模式和实际配比,进行当前盘次的物料的计量)可以包括如下步骤:
步骤S220:在骨料的含水率变化率大于第一预设阈值时,确定当前盘次的水的计量模式为二次计量模式。
二次计量模式指物料的计量次数为两次,包括首次计量和第二次计量,两次计量合计为该物料的最终用量。当含水率变化率大于第一预设阈值时,说明当前批次的骨料含水率存在一定差异性,即水的用量受骨料含水率影响较大,且无法将上一盘次的骨料的含水率直接应用于当前盘次,此时对水采用二次计量模式是更加可靠准确的,如此可以在二次计量水时对应调整水的用量。
步骤S221:基于当前盘次的物料的预设配比目标值和第一预设比例,确定当前盘次的水的首次计量值,并基于当前盘次的水的首次计量值对当前盘次的水进行首次计量。
首次计量值为执行二次计量模式的物料,于第一次计量时的用量值。第一预设比例为***预设的数值,具体数值可以根据生产需要预先设置,如设置为70%-90%均可,此处不对此作出进一步限定。以第一预设比例为70%举例,水的首次计量值可以为预设目标配比值的70%。
步骤S222:基于当前盘次的骨料的含水率和预设配比目标值,确定当前盘次的水的实际配比,基于当前盘次的水的实际配比和当前盘次的水的首次计量值确定当前盘次的水的二次计量值,并基于当前盘次的水的二次计量值对当前盘次的水进行二次计量。
二次计量值指物料在进行了首次称量后,依据当前盘次中骨料的含水率,第二次对物料进行计量的值,也可理解为在调整骨料与水的最终的实际配比时,所二次添加的水的质量,其用以使得实际配比更加接近预设配比目标值。由于步骤S220中含水率变化率大于1,说明当前批次骨料的含水率具有一定变化,相近程度不高。因此生产过程中,骨料中含水的不确定性增加,且无法参考上一盘次骨料的含水率来确定当前盘次骨料的含水率,此时通过预先减少水的用量,预留出对水进行二次计量的调整空间是更加有效的控水方式。减少水的用量可以使得在当前盘物料的骨料含水率确定后,及时调整当前盘物料的骨料与水的配比,使其更加接近骨料与水的标准配比,保证生产质量。在获取到当前盘次物料的含水率检测数据后,***可以计算出当前盘的骨料的含水率,进而计算出骨料中水的质量,结合水的首次计量值,即可计算出当前盘中水的用量与标准配比时水的用量的差值,将此差值作为水的二次计量值是准确可行的。在水的二次计量值计算完成后,对应称量水后加入至当前盘次物料中,即物料的最终实际配比确定,随后按照生产流程继续生产即可,如此使得骨料与水的实际配比更加接近标准配比,提高了生产质量。
应当理解,当含水率变化率大于第一预设阈值时,对于骨料的计量模式还应视含水率变化率的大小进一步确定,下面将就含水率变化率介于第一预设阈值和第二预设阈值之间的情况作出介绍。
具体的,如图2所示,当骨料的含水率变化率大于第一预设阈值且小于或等于第二预设阈值时,步骤S200(基于当前盘次的物料的预设配比目标值和第一预设比例,确定水的首次计量值,并基于水的首次计量值对当前盘次的水进行首次计量)和步骤S300(基于计量模式和实际配比,进行当前盘次的物料的计量)可以包括如下步骤:
步骤S230:在骨料的含水率变化率大于第一预设阈值且小于或等于第二预设阈值时,确定当前盘次的骨料的计量模式为单次计量模式。
第二预设阈值同理第一预设阈值,其可以作为当前批次骨料含水率不趋同但相差程度可控的判断依据。下面以第二预设阈值为2进行举例说明,即当1<V≤2时,依然需要获取上一盘物料的含水率检测数据,但后续处理步骤有所不同。
步骤S231:基于当前盘次的物料的预设配比目标值和上一盘次的骨料的含水率确定当前盘次的骨料的实际配比。
将预设配比目标值中的骨料质量以及上一盘物料的骨料含水率代入上述公式一,即可计算出当盘的骨料用量。通过这种方式计算出的骨料实际配比更加符合骨料的含水率现状,使用骨料含水率参数时更加便捷省时。
步骤S232:基于单次计量模式和当前盘次的骨料的实际配比,进行当前盘次的骨料的计量。
含水率变化率介于1和2之间,说明当前批次骨料的含水率具有一定变化,但相差尚在可控范围内。实际生产过程中,骨料用量往往远大于水的用量,因此此时采用单次计量模式对骨料进行计量是更加合理高效的。
在一种可能的实现方式中,如图2所示,当含水率变化率大于第二预设阈值时,步骤S200(基于当前盘次的物料的预设配比目标值和第一预设比例,确定水的首次计量值,并基于当前盘次的水的首次计量值对当前盘次的水进行首次计量)和步骤S300(基于计量模式和实际配比,进行当前盘次的物料的计量)还可以包括如下步骤:
步骤S240:在骨料的含水率变化率大于第二预设阈值时,确定当前盘次的骨料的计量模式为二次计量模式,第二预设阈值大于第一预设阈值。
下面继续以第二预设阈值为2举例说明,当V>2时,说明当前批次的骨料含水率差别较大,上一盘次物料的骨料含水率对于当前盘次物料的骨料含水率参考意义不大。此时在首次称量骨料和水时不宜结合上一盘物料的骨料含水率,且骨料也应采用二次计量模式,即按照一定比例减少骨料和水的用量,并将其作为首次称量的预测配比更加便于后续骨料与水的配比调整是更加可靠有效的,即对骨料和水均采用二次计量模式。
步骤S241:基于当前盘次的物料的预设配比目标值和第二预设比例确定当前盘次的骨料的首次计量值,并基于当前盘次的骨料的首次计量值对当前盘次的骨料进行首次计量。
第二预设比例同理第一预设比例,仅为不同模式下用于进行骨料或水的首次计量的比例。需要说明的是,第一预设比例、第二预设比例可以相等也可以不等,具体数值应视具体的应用场景而定。
步骤S242:基于当前盘次的骨料的实际配比和当前盘次的骨料的首次计量值确定当前盘次的骨料的二次计量值,并基于当前盘次的骨料的二次计量值对当前盘次的骨料进行二次计量。
当含水率变化率大于2时,首次计量的骨料为减少量的计量,因此在获取到当前盘物料的骨料含水率后,将其代入预设公式,即可计算得出骨料的调整量,即骨料的二次计量质量。
应当理解,由于第二预设阈值大于第一预设阈值,当含水率大于第二预设阈值时,必然大于第一预设阈值。此时,基于步骤S220至步骤S222可知,此条件下,当前盘次的水也应为二次计量模式,即当前盘次的骨料与水均采取二次计量模式,当前盘次水的首次计量和二次计量过程可参考上述步骤,此处将不再赘述,但需指出的是此种情况下,前述步骤S222中的步骤“基于当前盘次的骨料的含水率和预设配比目标值,确定当前盘次的水的实际配比”可以包括:基于当前盘次的骨料的含水率和预设配比目标值,确定当前盘次的骨料的实际配比和水的实际配比,也就是说,当前盘次的骨料的实际配比和当前盘次的水的实际配比均是基于当前盘次的骨料的含水率和预设配比目标值确定。
将上述骨料和水的调整量分别计量后,将其用于当前盘次的物料中的骨料和水的实际配比调整即可,待称量完成并加入其中后,继续按照生产流程生产,如此可以使得骨
料和水的实际配比更加接近标准配比。
在一种可能的实现方式中,图3所示为本申请另一实施例提供的搅拌站的自适应控水方法的流程示意图。如图3所示,步骤S100进一步可以包括如下步骤:
步骤S110:获取当前盘次之前的多个盘次的物料的含水率。
当前盘次之前的多个盘次为***为计算不同生产盘中的物料的含水率变化率所预先选择的生产盘。其中,多个盘次的数量可以为连续的5盘、10盘或15盘等,优选为10盘。如需计算第11盘的物料含水率变化率,则分别1-10盘次的含水率,待接收到检测数据后,分别计算其含水率,并根据这10盘次的含水率计算第11盘次物料的含水率变化率。
应当理解,上述取10盘计算含水率变化率仅为举例说明,并非对于数量的限制,具体盘数应视具体的应用场景而定,本申请不对此作出进一步限定。下文将仍以10盘举例,不再赘述。
步骤S120:基于多个盘次的物料的含水率,获取物料的含水率变化率。
利用步骤S110中计算得出的物料的含水率,计算含水率变化率V,如此可以直观地判断出当前批次的骨料含水率变化情况,从而确定预设盘外的生产盘该如何设置实际配比。
可选的,如图3所示,针对上述任一种情况,此方法还可以包括如下步骤:
步骤S400:检测当前盘次的物料的含水率。
含水率为含水率检测装置在搅拌站的输送皮带,如斜皮带,检测的当前盘物料的骨料的含水率感应数据,当含水率检测装置启动后,该装置可以持续进行骨料含水率检测数据的获取。控制***会根据预设时间间隔或当前需要获取含水率检测装置所检测到的数据,并对该数据进行处理计算等(如采用四分法后再取平均值获取最终含水率值等方式均可实现),最终得出骨料的含水率。
步骤S410:对应保存当前盘次的物料的含水率和盘号。
在当前盘次物料的含水率计算得出后,进行含水率值和对应生产盘的盘号的保存,如此可以提高数据的可追溯性,便于进行数据分析等工作。
具体的,图4所示为本申请另一实施例提供的搅拌站的自适应控水方法中含水率检测方法的流程示意图如图4所示,步骤S400(检测当前盘次的物料的含水率)进一步可以包括如下步骤:
步骤S401:在计量斗对当前盘次的物料进行卸料时,获取当前盘次的物料的卸料速度。
计量斗是搅拌站中用于进行物料计量的装置,卸料速度指的是***在输入标准配比启动生产后,同时骨料称量完成后,控制***会控制某种骨料开始卸料,此时骨料装载到输送生产盘上的装载速度。
值得一提的是,此步骤的卸料速度获取以及骨料厚度获取为间歇性获取过程,即***可以预设时间间隔,定时进行这两种卸料参数的获取即可。
步骤S402:在当前盘次的物料的卸料速度大于或等于预设速度阈值的情况下,检测当前盘次的物料的含水率。
预设速度阈值为***中预设的用于判断当前卸料速度是否正常的临界阈值,即当卸料速度小于该阈值时,说明骨料卸料速度过慢,可能存在异常,如砂子结块等情况,此时若开始进行生产或含水率的检测均容易形成无效数据,应待异常问题解决后再开始监测。因此,当骨料的卸料速度满足大于或等于对应阈值时,开始进行检测或进行数据的记录。
具体的,图5所示为本申请另一实施例提供的搅拌站的自适应控水方法中含水率检测方法的流程示意图。如图5所示,步骤S402(在当前盘次的物料的卸料速度大于或等于预设速度阈值的情况下,检测当前盘次的物料的含水率)进一步可以包括如下步骤:
步骤S4021:在当前盘次的物料的卸料速度大于或等于预设速度阈值的情况下,若从计量斗卸出的当前盘次的物料到达含水率检测区域,则检测当前盘次的物料的含水率。
不难理解骨料由计量斗移动至含水率检测处时会存在一定的延迟时间,鉴于这种情况,应待骨料到达含水率检测区域时再对其进行检测,提高检测的有效性。
在一种可能的实现方式中,如图5所示,步骤S4021(在当前盘次的物料的卸料速度大于或等于预设速度阈值的情况下,若从计量斗卸出的当前盘次的物料到达含水率检测区域,则检测当前盘次的物料的含水率)还可以包括如下步骤:
步骤S40211:若从计量斗卸出的当前盘次的物料到达含水率检测区域,且含水率检测区域的当前盘次的物料的厚度大于或等于预设厚度阈值,则检测当前盘次的物料的含水率。
物料的厚度指的是骨料平铺在输送皮带上的厚度。预设厚度阈值为***中预设的用于判断当前输送皮带上的骨料卸料是否正常的临界厚度值,当骨料的当前厚度较小,也说明卸料异常,此时获取数据仍然极有可能获取到无效数据。卸料速度和骨料厚度均是可以判断当前骨料卸料过程是否正产的重要参数,获取这两个参数可以进一步确保骨料卸料的正常进行。
具体的,如图5所示,在步骤S4021后,此搅拌站的自适应控水方法还可以包括如下步骤:
步骤S40212:当计量斗对当前盘次的物料进行卸料的时长达到临界时长时,确定计量斗卸出的当前盘次的物料到达含水率检测区域。
临界时长即为物料由卸料处到达含水率检测区域的所需时长,临界时长预设公式为用于计算骨料到达含水率检测装置安装位置的延时的公式,具体见公式三:
其中,tx为骨料开始卸料时刻到含水率检测装置启动时刻的临界时长;Sx指含骨料的卸料位置至输送装置的斜皮带的底部的长度;S1是指含水率检测装置的安装位置至斜皮带的底部的长度;V1指输送装置的平皮带的速度;V2指斜皮带的速度。
当上述骨料开始卸料时刻到含水率检测装置启动时刻的临界时长计算得出后,即可获取到骨料到达含水率检测点的时间,此刻生成含水率检测指令,并启动含水率检测装置是更加准确有效的。
此外,含水率检测装置的停止也可自动进行,即待当前批次的骨料完成卸料后,同样延迟tx时间后停止检测是更加可行的,以免骨料的含水率检测进行的不完全。
综上内容所述可知,在本申请一实施例中,图6所示为本申请另一实施例提供的搅拌站的自适应控水方法中含水率检测方法的流程示意图。如图6所示,上述搅拌站的自适应控水方法中骨料含水率的获取方法具体可以依照如下流程进行:
程序开始,搅拌站启动生产,根据物料的含水率变化率确定物料的计量模式和实际配比,基于计量模式对骨料和水进行计量,待计量完成开始进行卸料工序,卸料过程中,对骨料的卸料速度进行检测,此时若卸料速度结合上述临界时长不能满足预设速度阈值,则认为当前数据异常,对设备间进行查看处理,将异常数据去除,若卸料速度可以满足预设速度阈值则说明卸料正常,继续检测其他参数。进一步的,根据上述公式三计算骨料到达含水率检测区域的延迟时间,并依据延迟时间确定骨料何时可以到达检测区域,骨料到达后检测骨料平铺时的厚度,若骨料厚度不满足预设厚度阈值,则认为骨料卸料异常,去除异常数据待数据正常再进行检测,若骨料厚度满足预设厚度阈值,则启动含水率检测设备,如含水率传感器等,开始进行骨料含水率的检测,至此骨料含水率的检测过程结束。
具体的,在另一实施例中,图7所示为本申请另一实施例提供的搅拌站的自适应控水方法中计量模式和实际配比确定方法的流程示意图。如图7所示,依据物料的含水率
变化率确定物料的计量模式以及实际配比,基于实际配比对骨料和水进行计量的整体逻辑如下:
开始程序,启动生产流程,以获取第十一盘次物料的含水率变化率为例说明,先分别获取前十盘次的骨料的含水率,并根据前十盘此骨料的含水率计算骨料含水率变化率V,其中,当V小于第一预设阈值1时,说明当前批次骨料的含水率接近,则可以利用上一盘次物料的含水率作为计算参数,计算得出当前盘次中骨料和水的实际配比值,并基于实际配比值分别计量骨料和水即可。在1<V≤2时,依然需要获取上一盘物料的含水率检测数据,但后续处理步骤有所不同,此时骨料采用单次计量模式,水则采用二次计量模式,具体过程可参见上述步骤S230-S232。当含水率变化率大于2时,说明当前批次不同盘次的骨料含水率差异较大,此时骨料与水均采用二次计量模式,且在首次计量水和骨料时,直接按照预设目标配比值的70%计量,随后再根据当前盘次骨料的含水率分别对水和骨料进行二次计量。待检测结束后,将当前盘次的骨料盘号与其对应的含水率数据对应存入报表,至此,当前盘次的骨料含水率获取以及配比计量结束。
