Description

Technical Field

[0001] The present invention relates to the technical field of building material transportation, and particularly to a method, device, equipment and storage medium for transporting and analyzing concrete. Background Art

[0002] Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide strength grade range. These characteristics make its application range very wide. It is not only used in various civil engineering projects, but also an important material in the shipbuilding industry, mechanical industry, ocean development, geothermal engineering, etc.

[0003] During the transportation of concrete, especially in the transportation of concrete in alpine regions, it is necessary to monitor the concrete at all times so that if there are quality problems with the concrete due to problems in the transportation process during use, it can be traced. At present, the Chinese patent "A Method for Monitoring the Transportation State of Concrete Based on Image Analysis and Processing", application number: 202110036950.X, discloses taking a large number of samples of concrete in various states in the transport vehicle for photographing and archiving, and constructing concrete comparison sample data stored in the base station data; the photographing device in the transport vehicle tank periodically photographs the state of the concrete in the pipe and compares and analyzes it with the archived data in the base station; through the feature comparison of the concrete in the transport vehicle, the state of the concrete during transportation is classified and remotely transmitted to the base station terminal; the comparison images are analyzed, and when it reaches the warning state, an alarm is remotely sent to the quality inspector of the mixing plant, and the dropping device in the transport vehicle is adjusted accordingly; until the transport vehicle reaches the destination, the monitoring and control ends. This prior art needs to send each photographed photo back to the base station for comparison respectively. For the sample data of various situations during the transportation process, at least 500 samples need to be taken respectively. The sampling times are many, the amount of transmitted data is large, and since the concrete needs to be kept out of light during transportation, the photographing environment of the photos is always dim, which affects the comparison result and may misjudge the transportation state of the concrete. Summary of the Invention

[0004] The main purpose of the present invention is to provide a method, device, equipment and storage medium for transporting and analyzing concrete, so as to solve the problems in the prior art that the sampling times are many, the amount of transmitted data is large, and the sampling environment is poor, resulting in inaccurate comparison results when collecting the concrete transportation state through photos.

[0018] Package the first serial number information and the second serial number information obtained at the same time, and integrate them with the position information of the vehicle to form a travel data packet of the vehicle;

[0019] Send each travel data packet to an external receiving end.

[0020] In some embodiments, the first numbered information and the second numbered information obtained at the same time are packaged and integrated with the position information of the vehicle to form a travel data packet of the vehicle. After that, it includes:

[0022] Connect the position information of adjacent time intervals to form the transportation trajectory of the vehicle;

[0023] Display the remaining duration on the first electronic map of the vehicle or the second electronic map of the external receiving end.

[0024] In some embodiments, within the remaining duration of the longest transportation time, the real-time temperature of the concrete is obtained at intervals of a first preset duration, and the difference between the current real-time temperature and the previous real-time temperature is obtained, and it is determined whether the difference is greater than or equal to zero; if so, the remaining duration is reduced according to a first preset ratio. After that, it includes:

[0025] Determine whether the difference is greater than or equal to a first preset threshold. If so, reduce the remaining duration according to a third preset ratio;

[0040] A storage medium stores program instructions therein, and when the program instructions are executed by a processor, the transportation analysis method of the concrete as described above can be implemented.

[0041] Beneficial effects: Since the main factors affecting the initial setting time of concrete are temperature and humidity, during transportation, the humidity change range of concrete in the closed space of the vehicle is small, and the initial setting time of concrete is mainly determined by the ambient temperature during the transportation of concrete. The present invention matches the corresponding longest transportation time according to the mix ratio of concrete, starts timing when the concrete is loaded into the transportation vehicle, and monitors the ambient temperature of the concrete in real time during transportation. When the ambient temperature rises, the remaining duration is reduced to remind the user that the initial setting time of the concrete will be advanced; when the temperature drops, the remaining duration is increased to remind the user that the initial setting time of the concrete will be delayed, which is convenient for the user to optimize the transportation route and speed, and avoid the concrete from initial setting before pouring is completed, thereby ensuring the good product rate of the concrete and improving the user experience.

Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features.

All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0048] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0049] An embodiment of the present application provides a method for analyzing the transportation of concrete. Refer to Figure 1 , which is a schematic flowchart of the method for analyzing the transportation of concrete provided by an embodiment of the present application. It should be noted that if there are substantially the same results, the method of the present application is not limited to the Figure 1 shown process sequence. In this embodiment, the transportation analysis method includes the following steps:

[0050] Step S1, in response to the user's concrete loading operation on the vehicle, obtain the real-time mixing ratio information of the concrete and match the longest transportation time of the concrete.

[0051] Preferably, the longest transportation time is obtained according to the specific initial setting times of concretes with different mix ratios from the previously conducted concrete mix proportion tests, so as to determine the relatively accurate initial setting times of concretes with different grades at different temperatures, which can be accurate to ±10 min or even shorter.

[0052] Step S2: Transmit the longest transportation time to the vehicle transporting the concrete, and the longest transportation time starts to decrease at a countdown rate.

[0053] Preferably, when the concrete starts the loading operation, the vehicle obtains the expected initial setting time corresponding to the mix ratio of the concrete, and starts the countdown based on this expected initial setting time.

[0054] Step S3: Within the remaining duration of the longest transportation time, obtain the real-time temperature of the concrete at intervals of a first preset duration, and obtain the difference between the current real-time temperature and the previous real-time temperature, and determine whether the difference is greater than zero; if so, execute Step S4; if not, execute Step S5.

[0055] Step S4: Reduce the remaining duration according to a first preset ratio.

[0056] Step S5: Determine whether the difference is less than zero, if so, execute Step S6.

[0057] Step S6: Increase the remaining duration according to a second preset ratio.

[0058] Preferably, the real-time temperature can be obtained every 5 min, and the currently obtained real-time temperature is compared with the real-time temperature obtained 5 min ago to obtain the above difference. If the difference is positive, it means that the current real-time temperature has increased compared with the real-time temperature obtained 5 min ago; if the difference is negative, it means that the current real-time temperature has decreased compared with the real-time temperature of the implementation environment obtained 5 min ago.

[0059] It should be noted that the transportation duration of the concrete is linearly and positively correlated with temperature and humidity. When the humidity remains unchanged, the higher the temperature, the faster the initial setting speed of the concrete, and the shorter the transportation duration; the lower the temperature, the slower the initial setting speed of the concrete, and the longer the initial setting time. However, when the ambient temperature drops to 5 °C, the concrete is prone to crystallization, which will affect the setting strength. When the ambient temperature drops to 5 °C, the transportation duration of the concrete is no longer considered.

[0060] Furthermore, from the start of mixing the concrete to loading it onto the transportation vehicle, the concrete starts to enter the initial setting stage in the mixing plant, and after the concrete is transported to the destination, operations such as discharging and placing in the bin are still required. Therefore, the longest transportation time of the concrete is significantly less than the initial setting duration of the concrete. Since the loading duration, discharging duration, and placing duration in the bin are all uncontrollable, this embodiment considers the controllable longest transportation time of the concrete, rather than the total initial setting duration of the concrete.

[0061] Preferably, the first preset ratio can conduct setting experiments on concrete with different mix ratios at different temperatures to determine the transportation duration.

[0062] For example: Let the temperature of concrete with a specific mix ratio (such as one of C20, C30, C50, etc.) at the completion of the mixing operation be T1, and the corresponding transportation duration be t1. After an interval of the first preset duration, the real-time temperature of the concrete is T2. The difference between the real-time temperature after this interval of the first preset duration and the real-time temperature of the previous node is ΔT = T2 - T1. If ΔT > 0, then the duration t2 that needs to be reduced at this time can be obtained according to the second preset ratio obtained where k1 is the proportionality coefficient, and k1 can be determined according to the slope of the function of the transportation duration and temperature of concrete with different mix ratios in the above setting experiment; if ΔT < 0, then the duration t2 that needs to be increased at this time can be obtained according to the second preset ratio obtained where k2 is also the proportionality coefficient, and k2 can be determined according to the slope of the function of the transportation duration and temperature of concrete with different mix ratios in the above setting experiment.

[0063] It should be noted that the formula is only used to illustrate the simple principle relationship between each sub-item. In actual applications, the principle relationship between each sub-item may be more specific or complex, or there may be more than one coefficient. This embodiment is only for principle demonstration and explanation, and is not used to limit the principle relationship between each sub-item in actual use.

[0064] Furthermore, the specific values of the first preset ratio and the second preset ratio need to be confirmed through the initial setting experiment of concrete. The values of the first preset ratio and the second preset ratio, that is, the values of k1 and k2, can be the same or different, or k1 and k2 are respectively functional relationships rather than constants.

[0065] For example: The temperature of concrete with mix ratio A at the completion of the mixing operation is 25°C, and the transportation duration is 1h. At this time, the vehicle obtains the transportation duration of 1h and starts counting down from 1h.

[0066] Case 1: If the vehicle is in a hot environment (such as 35°C), then after the first 5 minutes, the real-time temperature of the concrete rises from 25°C to 28°C. At this time, the difference between the two temperatures is 3°C, and the remaining duration at this time is 55 minutes. Assume that the value of k1 is 1 here, then according to the above formula, the first preset ratio is 0.12 Then the remaining duration of 55 minutes is reduced by 6.6 minutes according to the first preset ratio of 0.12, and the new remaining duration is 48.4 minutes.

[0067] Furthermore, after the second 5 minutes, the real-time temperature of the concrete drops from 22°C to 20°C. At this time, the difference between the two temperatures is -2°C, and the remaining duration is 43.4 minutes. Assuming the value of k1 is also 1 here, the first preset ratio is obtained according to the above formula as Then the remaining duration of 43.4 minutes is reduced according to the first preset ratio by approximately 3.95 minutes, and the new remaining duration is 39.45 minutes.

[0068] Case 2: If the vehicle is in a cold environment (such as 10°C), after the first 5 minutes, the real-time temperature of the concrete drops from 25°C to 22°C. At this time, the difference between the two temperatures is -3°C, and the remaining duration is 55 minutes. Assuming the value of k2 is 1 here, the first preset ratio is 0.12 obtained according to the above formula. Then the remaining duration of 55 minutes is increased according to the first preset ratio of 0.12 by 6.6 minutes, and the new remaining duration is 61.6 minutes.

[0069] Furthermore, after the second 5 minutes, the real-time temperature of the concrete drops from 22°C to 20°C. At this time, the difference between the two temperatures is -2°C, and the remaining duration is 56.6 minutes. Assuming the value of k2 is also 1 here, the first preset ratio is obtained according to the above formula as Then the remaining duration of 56.6 minutes is reduced according to the first preset ratio by approximately 5.15 minutes, and the new remaining duration is 51.45 minutes.

[0070] It should be noted that the above specific data are only used to illustrate the calculation principle of this embodiment. There may be deviations between the above specific data and the specific data in actual applications. In actual use, the transportation durations of concretes with different mix ratios (concrete grades) are different, and the coefficients k1 and k2 may be different. Moreover, the coefficients k1 and k2 may be a functional relationship rather than constants, that is, k1 and k2 are linearly related to temperature and time respectively. In actual use, the specific initial setting times and coefficients k1 and k2 of concretes with different mix ratios need to be determined according to the initial setting experiments carried out in advance.

[0071] Further explanation: The first interval duration can be set according to actual needs. The 5 minutes in the above example are for the convenience of illustration, and in the actual operation process, it can be set to a shorter interval time, or it can be set according to the change duration of unit temperature.

[0072] Further explanation: In this embodiment, the adjustment is made according to the remaining time rather than the total time, considering that the value of the activation energy E during the hydration of concrete at normal temperature is about 30 kJ / mol to 40 kJ / mol. Here, let E = 40 kJ / mol. When the reaction temperature rises from 20°C to 40°C, the value of the hydration reaction rate k increases by 185%. When the reaction temperature rises from 40°C to 60°C, the value of the reaction rate k increases by 624%. On the contrary, if the reaction temperature drops from 20°C to 10°C, the value of the reaction rate k decreases by 44.6%. When the reaction temperature drops from 10°C to 0°C, the value of the reaction rate k decreases by 7.03%. It can be seen from the above data that when the reaction temperature changes at a fixed slope, the reaction rate k of the concrete changes at a geometric slope, that is, within the countdown of the remaining time, the solidification rate of the concrete is not a fixed value. In this embodiment, increasing or decreasing the proportion of the remaining time is more in line with the solidification rate of the concrete.

[0073] Step S7, determine whether the remaining time reaches a preset warning time. If so, execute step S8.

[0074] Preferably, the preset warning time can be set to 10 min, or it can be set proportionally according to the overall transportation time.

[0075] Step S8, generate a warning signal and send it to an external receiving end.

[0076] As an implementation manner, further, step S1 includes:

[0077] Step S11, pre-store a number of different preset ratio information and a number of longest transportation times respectively matching each preset ratio information.

[0078] Step S12, obtain the preset ratio information identical to the real-time ratio information, and match the corresponding longest transportation time according to the identical preset ratio information.

[0079] Preferably, the experimental data of the initial setting experiments for concrete with different ratios and different temperatures can be set with different ratios as the classification basis, with temperature as the abscissa and transportation duration as the ordinate, forming multiple initial setting time coordinate systems for concrete with different ratios. Each coordinate system corresponding to the concrete ratio can be used as the preset ratio information, and each coordinate point in the coordinate system corresponding to the required preset ratio information can be used as the longest transportation time at different temperatures.

[0080] Preferably, the longest transportation time is fixed at the time of feeding and does not change with the temperature change during transportation. The temperature change during transportation is adjusted by the analysis method of the above embodiment.

[0081] As an implementation manner, further, after step S2, it includes:

[0082] Step S21, respectively obtain the first number information of the vehicle and the second number information of the blanking port for blanking the vehicle based on radio frequency identification at intervals of a second preset duration.

[0083] Step S22, package the first number information and the second number information obtained at the same time, and integrate them with the position information of the vehicle to form a travel data packet of the vehicle.

[0084] Step S23, send each travel data packet to an external receiving end.

[0085] Preferably, there may be multiple blanking ports in the concrete mixing plant. Based on multiple radio frequency identification devices, the numbers of the vehicles at their respective blanking ports are obtained in real time, and the production information of the mixing plant and the radio frequency identification information are coupled. Based on the time stamp, the information of the mixing plant, the vehicle information, the concrete mixing ratio information, and the concrete grade are integrated to realize the tracking of the concrete flow direction.

[0086] Preferably, due to the spatial characteristics of multiple blanking ports and the direction characteristics of radio frequency identification devices, the installation design of radio frequency identification devices is carried out: aiming at the problem that the channels of the multi-blanking port mixing plant are relatively narrow, by analyzing the sensing range and angle of each radio frequency identification device, the installation position and angle of the radio frequency identification device are controlled; at the same time, based on the radio frequency identification device, the vehicle numbers at the blanking ports are obtained in real time, and the transport vehicle equipment numbers at the blanking ports and the induction time of each time are obtained by using the radio frequency identification device.

[0087] As an implementation manner, further, after step S22, it includes:

[0088] Step S31, output and display each position information in the first electronic map of the vehicle or the second electronic map of the external receiving end.

[0089] Step S32, connect the position information of adjacent intervals of time periods to form the transport trajectory of the vehicle.

[0090] Step S33, display the remaining duration on the first electronic map of the vehicle or the second electronic map of the external receiving end.

[0091] Preferably, the first electronic map of the vehicle or the second electronic map of the external receiving end can be displayed on the display device of the vehicle or the display device of the external receiving end. The above display device can be an electronic device equipped with an electronic map, and this electronic device can be a terminal device. For example, mobile phones, tablets, PDAs, etc. The terminal device can install an operating system, which can include Android, iOS, Windows Phone, Windows, etc., and generally can support the operation of various electronic map software. By running an electronic map application or a map applet in other applications on the terminal device and rendering a graphical user interface (User Interface, UI) on the display screen of the terminal device, the content displayed on the graphical user interface at least partially includes the regional electronic map where the running track of the vehicle is located. The specific form of the electronic map can be a 2D map or other types of electronic maps (such as 3D maps or satellite maps, etc.).

[0092] Preferably, the real-time position of the vehicle can be displayed as a point or a thumbnail with the appearance of the vehicle as a coordinate point on the electronic map. The coordinate point moves on the electronic map following the real-time position of the vehicle, and information such as vehicle information and remaining duration can be displayed on one side of the coordinate point.

[0093] As an implementation manner, further, after step S3, it includes:

[0094] Step S41, determine whether the difference is greater than or equal to the first preset threshold. If so, reduce the remaining duration according to the third preset ratio;

[0095] Step S42, generate an overheat warning message and send it to the external receiving end.

[0096] For example, referring to the characteristics of the activation energy E during the hydration of concrete at normal temperature above, assume E = 40 kJ / mol. When the reaction temperature rises from 20°C to 40°C, the value of the hydration reaction rate k increases by 185%. When the reaction temperature rises from 40°C to 60°C, the value of the reaction rate k increases by 624%. It can be seen from this data that when the reaction temperature changes at a fixed slope, the reaction rate k of the concrete changes at a geometric slope. That is, during the countdown of the remaining duration, the solidification rate of the concrete is not a fixed value. When the temperature is relatively high, the growth rate of the value of the reaction rate k significantly increases. That is, when the difference is greater than the first preset threshold, the concrete significantly heats up, and the value of the proportionality coefficient k3 in the third preset ratio needs to be significantly greater than the value of k1 or k2 to reflect the sudden increase in the reaction rate of the concrete.

[0097] Example: For example, the temperature of the concrete with mix ratio A when the mixing operation is completed is 25°C, and the transportation duration is 1 hour. At this time, the vehicle obtains the transportation duration of 1 hour and starts a countdown with 1 hour. Let the first preset threshold be 5°C.

[0098] Situation 3: If an abnormality occurs in the transport box of the vehicle during transportation or the weather temperature is too high, then after the first 5 minutes, the real-time temperature of the concrete rises from 25°C to 30°C. At this time, the difference between the two temperatures is 5°C, reaching the first preset threshold, and the remaining duration is 55 minutes. Here, let the value of k3 be 2, then according to the above formula, the first preset ratio is 0.24 Then the remaining duration of 55 minutes is reduced by 13.2 minutes according to the third preset ratio of 0.24, and the new remaining duration is 41.8 minutes.

[0099] Furthermore, the specific value of the third preset ratio needs to be confirmed through the initial setting experiment of the concrete. The third preset ratio, that is, the value of k3, may be a functional relationship rather than a constant.

[0100] It should be noted that the above specific data is only used to illustrate the calculation principle of this embodiment. There may be deviations between the above specific data and the specific data in actual applications. Moreover, in actual use, the transportation durations of concretes with different mix ratios (concrete grades) are different. The coefficient k3 may be a functional relationship rather than a constant, that is, k3 is linearly related to temperature and time respectively. In actual use, it is necessary to determine the specific initial setting time and coefficient k3 of concretes with different mix ratios according to the initial setting experiment carried out in advance.

[0101] Further explanation: The first interval duration can be set according to actual needs. The 5 minutes in the above example is for the convenience of illustration. In the actual operation process, it can be set to a shorter interval time, or it can be set according to the change duration of the unit temperature.

[0102] As an implementation manner, further, after step S12, it includes:

[0103] Step S51, determine whether the real-time temperature is less than or equal to the second preset threshold. If so, execute step S52.

[0104] Step S52, pause the remaining duration.

[0105] Step S53, generate an overcooling warning message and the real-time position information of the vehicle.

[0106] Step S54, send the overcooling warning message and the real-time position information to an external receiving end.

[0107] Preferably, since concrete is prone to crystallization during setting in a supercooled environment, which affects the setting strength of the concrete, without adding an anticoagulant to the concrete, crystallization may occur when the temperature of the concrete is 5°C. Different second preset thresholds can be set according to different proportions and additives of the concrete. In this embodiment, 0°C is preferably used as the supercooling warning temperature.

[0108] Preferably, the remaining time and the warning signal can be output and displayed on the vehicle.

[0109] In this embodiment, the longest transportation time is matched according to the proportion of the concrete. Timing starts when the concrete is loaded into the transport vehicle, and the ambient temperature of the concrete is monitored in real time during transportation.
