The appearances of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those skilled in the art understand, both explicitly and implicitly, that the embodiments described herein may be combined with other embodiments.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

Figure 1 shows a schematic flow chart of an adaptive water control method for a mixing station provided by an embodiment of the present application. As shown in Figure 1, 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.

Materials can refer to the same or different types of aggregate and water in any production tray. 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. . When the change rate of moisture content is large, it means that the moisture content of this batch of aggregates is unstable, and the moisture content of aggregates in different trays varies greatly; when the change rate of moisture content is small, it means that the moisture content of this batch of aggregates is unstable. The rate is stable, and the moisture content of the aggregates on different plates is close. Referring to 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. Proportion value; 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.

Since 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 provided by this application 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.

In a possible implementation, 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. As shown in Figure 2, considering the different change rates of the moisture content of the aggregate, 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.

Specifically, the weight of the current material aggregate can be calculated according to the following formula 1:

Among them, 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, and 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.

Calculate the weight of the current tray of material water according to the following formula 2:

Among them, n represents the number of aggregate types in the current plate.

Combined with the preset ratio target value of aggregate and water in the current tray of materials and the moisture content of the previous tray of materials, 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.

In another possible implementation, as shown in Figure 2, the adaptive water control method provided by the present application will be described below using materials including aggregate and water. When the moisture content change rate is greater than the first preset threshold, 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) and step S300 (measurement of the current batch of materials based on the measurement mode and actual proportion) may include the following steps:

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. When 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. At this time, by reducing the amount of water in advance, reserve a certain amount of water. 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. After obtaining the moisture content detection data of the current plate of materials, the system can calculate the moisture content of the aggregate in the current plate, and then calculate the quality of water in the aggregate. Combined with the first measured value of water, 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. After the calculation of the secondary measurement value of water is completed, 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.

It should be understood that when the moisture content change rate is greater than the first preset threshold, 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.

Specifically, as shown in Figure 2, 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, 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.

Substituting the aggregate mass in the preset ratio target value and the aggregate moisture content of the previous plate of materials into the above formula 1, 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. In the actual production process, 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.

In a possible implementation, as shown in Figure 2, 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 following continues to use the second preset threshold value of 2 as an example. When 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. At this time, it is not appropriate to combine the aggregate moisture content of the previous plate of materials when weighing the aggregate and water for the first time, and 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.

When the change rate of moisture content is greater than 2, 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.

It should be understood that since 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. At this time, based on steps S220 to S222, it can be known that under this condition, 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. However, it should be pointed out that in this case, 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.

After measuring the above-mentioned adjusted amounts of aggregate and water separately, use them to adjust the actual ratio of aggregate and water in the current batch of materials. After the weighing is completed and added, continue production according to the production process. , which can make the bone The actual ratio of ingredients and water is closer to the standard ratio.

In a possible implementation, FIG. 3 shows a schematic flowchart of an adaptive water control method for a mixing station provided by another embodiment of the present application. As shown in Figure 3, step S100 may further include the following steps:

Step S110: Obtain the moisture content of materials in multiple batches before the current batch.

The multiple trays before the current tray 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. The change rate of moisture content of secondary materials.

It should be understood that the above calculation of the moisture content change rate using 10 disks is only an example and is not a limit on the quantity. The specific number of disks should depend on the specific application scenario, and this application does not further limit this. The following will still use 10 disks as an example and will not go into details.

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.

Optionally, as shown in Figure 3, for any of the above situations, this method can also include the following steps:

Step S400: Detect the moisture content of the current batch of materials.

The moisture content detection device is installed on the conveyor belt of the mixing station, such as an inclined belt, to detect the moisture content sensing data of the aggregate of the current tray of materials. When the moisture content detection device is started, the device can continue to detect the moisture content of the aggregate. Acquisition of data. The control system will obtain the data detected by the moisture content detection device according to the preset time interval or current needs, and process and calculate the data (such as using the quartering method and then taking the average to obtain the final moisture content value). Realized), and finally get the moisture content of the aggregate.

Step S410: Save the moisture content and tray number of the current tray of materials accordingly.

After the moisture content of the current tray of materials is calculated, the moisture content value and the tray number of the corresponding production tray are saved. This can improve the traceability of the data and facilitate data analysis and other work.

Specifically, Figure 4 shows a schematic flow chart of the moisture content detection method in the adaptive water control method of the mixing station provided by another embodiment of the present application. As shown in Figure 4, step S400 (detecting the moisture content of the material in the current batch) ) may further include the following steps:

Step S401: When the weighing hopper unloads the current batch of materials, obtain the unloading speed of the current batch of materials.

The measuring hopper is a device used for material measurement in the mixing station. The unloading speed refers to the system that starts production after inputting the standard ratio and at the same time after the aggregate weighing is completed, the control system will control a certain aggregate to start unloading. The loading speed at which the aggregate is loaded onto the conveyor production tray at this time.

It is worth mentioning that 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. Therefore, when the aggregate unloading speed is greater than or equal to the corresponding threshold, detection or data recording begins.

Specifically, FIG. 5 shows a schematic flow chart of the moisture content detection method in the adaptive water control method of the mixing station provided by another embodiment of the present application. As shown in Figure 5, step S402 (detecting the moisture content of the current batch of materials when the unloading speed of the current batch of materials is greater than or equal to the preset speed threshold) may further include the following steps:

Step S4021: When the unloading speed of the current batch of materials is greater than or equal to the preset speed threshold, if the current batch of materials discharged from the weighing hopper reaches the moisture content detection area, detect the moisture content of the current batch of materials. Moisture content.

It is not difficult to understand that there will be a certain delay time when the aggregate moves from the measuring hopper to the moisture content detection area. In view of this situation, the aggregate should be tested when it reaches the moisture content detection area to improve the effectiveness of the detection.

In a possible implementation, as shown in Figure 5, step S4021 (when the unloading speed of the current batch of materials is greater than or equal to the preset speed threshold, if the current batch of materials discharged from the weighing hopper When the material reaches the moisture content detection area, detecting the moisture content of the material in the current batch) may also include the following steps:

Step S40211: If the current batch of materials unloaded from the weighing hopper reaches the moisture content detection area, and the thickness of the current batch of materials in the moisture content detection area is greater than or equal to the preset thickness threshold, detect the thickness of the current batch of materials. Moisture content.

The thickness of the material refers to the thickness of the aggregate laid flat on the conveyor belt. The preset thickness threshold is the critical thickness value preset in the system to determine whether the current aggregate discharge on the conveyor belt is normal. 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. The unloading speed and aggregate thickness are important parameters that can determine whether the current aggregate unloading process is in progress. Obtaining these two parameters can further ensure the normal progress of aggregate unloading.

Specifically, as shown in Figure 5, after step S4021, the adaptive water control method of the mixing station may also include the following steps:

Step S40212: When the time for the measuring hopper to discharge the current batch of materials reaches the critical time, it is determined that the current batch of materials discharged from the measuring hopper reaches the moisture content detection area.

The critical time is the time required for the material to reach the moisture content detection area from the unloading point. The preset formula for the critical time is the formula used to calculate the delay for the aggregate to reach the installation position of the moisture content detection device. For details, see Formula 3:

Among them, tx is the critical time from the time when the aggregate starts to be unloaded to the time when the moisture content detection device is started; Sx refers to the length from the unloading position of the aggregate to the bottom of the inclined belt of the conveyor; S1 refers to the installation of the moisture content detection device The length from the position to the bottom of the inclined belt; V1 refers to the speed of the flat belt of the conveyor; V2 refers to the speed of the inclined belt.

When the critical time from the time when the above-mentioned aggregate starts to be unloaded to the time when the moisture content detection device is started is calculated, the time when the aggregate reaches the moisture content detection point can be obtained. At this time, the moisture content detection command is generated and the moisture content detection device is started. is more accurate and effective.

In addition, the stop of the moisture content detection device can also be carried out automatically. That is, after the current batch of aggregates is discharged, it is more feasible to stop the detection after delaying the tx time to avoid incomplete moisture content detection of the aggregates.

In summary, it can be seen that in one embodiment of the present application, FIG. 6 shows a schematic flow chart of the moisture content detection method in the adaptive water control method of the mixing station provided by another embodiment of the present application. As shown in Figure 6, the method for obtaining the aggregate moisture content in the adaptive water control method of the above-mentioned mixing station can be carried out according to the following process:

At the beginning of the program, the mixing station starts production. The measurement mode and actual proportion of the material are determined based on the moisture content change rate of the material. The aggregate and water are measured based on the measurement mode. After the measurement is completed, the unloading process begins. During the unloading process, Detect the unloading speed of the aggregate. At this time, if the unloading speed combined with the above-mentioned critical time cannot meet the preset speed threshold, the current data will be considered abnormal. The equipment room will be viewed and processed to remove the abnormal data. If the unloading speed can If the preset speed threshold is met, it means that the discharge is normal and other parameters will continue to be detected. Further, calculate the delay time for the aggregate to reach the moisture content detection area according to the above formula 3, and determine when the aggregate can reach the detection area based on the delay time. After the aggregate arrives, the thickness of the aggregate when it is laid out is detected. If the aggregate thickness If the aggregate thickness does not meet the preset thickness threshold, it is considered that the aggregate unloading is abnormal. The abnormal data will be removed and the data will be normal before detection. If the aggregate thickness meets the preset thickness threshold, the moisture content detection equipment, such as a moisture content sensor, etc. will be started and the process will begin. Detection of aggregate moisture content. This is the end of the detection process of aggregate moisture content.

Specifically, in another embodiment, FIG. 7 is a schematic flowchart 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. As shown in Figure 7, according to the moisture content of the material The rate of change determines the measurement mode and actual proportion of materials. The overall logic of measuring aggregate and water based on the actual proportion is as follows:

Start the program and start the production process. Taking the change rate of moisture content of the eleventh tray of materials as an example, first obtain the moisture content of the aggregates in the first ten trays and calculate it based on the moisture content of the aggregate in the first ten trays. Aggregate moisture content change rate V, where, when V is less than the first preset threshold 1, it means that the moisture content of the current batch of aggregates is close, and the moisture content of the previous batch of materials can be used as the calculation parameter to calculate The actual ratio of aggregate and water in the current batch is determined, and the aggregate and water are measured separately based on the actual ratio. When 1<V≤2, it is still necessary to obtain the moisture content detection data of the previous plate of materials, but the subsequent processing steps are different. At this time, the aggregate adopts the single measurement mode, and the water adopts the secondary measurement mode. The specific process can be See steps S230-S232 above. When the moisture content change rate is greater than 2, it means that the moisture content of the aggregates in different batches of the current batch is greatly different. At this time, both aggregate and water adopt the secondary measurement mode, and when measuring water and aggregate for the first time, directly follow the 70% of the preset target proportion value is measured, and then the water and aggregate are measured twice according to the moisture content of the current batch of aggregates. After the test is completed, the aggregate tray number of the current batch and its corresponding moisture content data will be stored in the report. At this point, the acquisition of the aggregate moisture content of the current batch and the proportion measurement are completed.
