Description

Technical Field

[0001] The present invention relates to the field of building materials management, and in particular to a management method and system for building materials in severely cold regions. Background Art

[0002] Ready-mixed concrete is an important component of my country's building materials. With its advantages of low price and high strength, it occupies a key position in the building materials market. In some severely cold areas, ready-mixed concrete has the advantages of only needing to be poured at the construction site, and can be constructed normally regardless of severe cold, and the temperature of the concrete is easy to control during transportation. However, in actual production and use, if the construction area is large and the demand for ready-mixed concrete is large, a single ready-mixed concrete plant is difficult to meet the demand, especially affected by the tight construction period during the construction process. At present, multiple factories are often used to supply ready-mixed concrete. However, due to the condensability of concrete itself and the influence of construction speed requirements, how to ensure the continuous supply between multiple factories and ensure the transportation quality of ready-mixed concrete is a problem that needs to be solved urgently.

[0003] Chinese patent publication number CN115545615A discloses a novel low-carbon pre-mixed concrete supply method and supply information management system, the method comprising the following steps: S1, the construction end sends order information to the batching end; S2, the batching end conducts a ratio design test, and implements the batching process after passing the test; S3, the transportation end generates a transportation route and dispatches the transportation; S4, the transportation vehicle arrives at the batching end and loads the materials, and when loading, water, admixtures and other materials are separated and placed in the vehicle facilities; S5, the transportation vehicle distributes the materials; S6, after arriving at the construction site, water, admixtures and other materials are mixed and vibrated and stirred; S7, the transportation vehicle completes the distribution task;

[0004] S8. After the transportation and usage of concrete reaches the order requirements, the order task is completed. It can be seen that the novel low-carbon premixed ready-mixed concrete supply method and supply information management system have the following problems: it is impossible to set the supply order according to the actual supply capacity of each factory in the scenario where multiple factories supply ready-mixed concrete, which leads to too long a time interval between the delivery vehicles of each concrete delivery vehicle, resulting in too long waiting time for pouring and affecting the quality of the project, or too short a time interval between the delivery vehicles of each concrete delivery vehicle, resulting in poor utilization of the transportation vehicles. Summary of the invention

[0005] To this end, the present invention provides a management method and system for building materials in severe cold regions, so as to overcome the problem of poor control effect of the delivery time interval of concrete delivery vehicles in the prior art.

[0006] To achieve the above object, the present invention provides a management method for building materials in severe cold regions, comprising:

[0010] S4, in response to the first feedback adjustment condition, the feedback adjustment unit determines the delivery method of each effective supply factory according to the transportation reference quantity of the effective supply factory, including that the delivery vehicles of each effective supply factory arrive at the demand area in sequence for uniform delivery and that the corresponding effective supply factory is graded according to the supply characteristic parameters of each effective supply factory and graded delivery with different transportation times;

[0011] S5, in response to the second feedback adjustment condition, the feedback adjustment unit performs adjustment determination of the vehicle interval time range and the preset interval time range;

[0013] Further, the data analysis unit determines the demand quantity of the supply plant according to the demand concrete quantity of the demand area under the analysis trigger condition;

[0014] The required amount of concrete is positively correlated with the demand quantity of the supply factory;

[0015] The analysis trigger condition is that the interaction unit inputs demand information.

[0016] Further, the data analysis unit extracts supply factories within the selectable range of the demand area under the first data analysis condition, which is recorded as the number of optional factories, and determines the concrete production allocation method according to the number of optional factories, including: determining the concrete production volume of each optional factory according to the position coordinates of each optional factory when the number of optional factories meets the supply demand,

[0017] Or, when the number of optional plants meets the shortage of supply, the area of ​​the optional range is adjusted according to the number of optional plants to re-determine the concrete production allocation method;

[0018] Among them, the first data analysis condition is that the supply factory selection quantity is determined and completed.

[0019] Furthermore, the data analysis unit extracts the location coordinates of the optional factories under the second data analysis condition, selects n optional factories in the order of the shortest driving route length to the demand area from small to large, and records them as effective supply factories, and other optional factories are recorded as invalid selected factories and eliminated, and the data analysis unit calculates the reference distance stability S, and sets,

[0020]

[0021] Among them, Li is the shortest driving route length between the i-th effective supply factory and the demand area, n is the demand quantity;

[0022] The data analysis unit determines the concrete production of each effective supply plant according to the reference distance stability S, including:

[0023] When the reference distance stability meets the first preset stability range, the concrete production of each effective supply plant is set to be the same;

[0024] When the reference distance stability meets the second preset stability range, the corresponding concrete production volume is determined according to the shortest driving route length between each effective supply plant and the demand area;

[0025] Among them, the second data analysis condition is that the number of optional factories meets the supply demand status.

[0026] Further, the data analysis unit calculates the absolute value of the difference between the number of optional factories and the required number under the third data analysis condition, records it as a reference difference, and the data analysis unit increases the area of ​​the selectable range according to the reference difference;

[0027] The reference difference value is positively correlated with the increase in the area of ​​the selectable range;

[0028] The third data analysis condition is that the number of optional factories satisfies the shortage of supply.

[0029] Further, the feedback adjustment unit determines the delivery method of each effective supply factory according to the transportation reference quantity of the effective supply factory under the first feedback adjustment condition;

[0030] If the transport reference quantity of the effective supply factory is in a stable transport condition, the feedback adjustment unit determines that each effective supply factory delivers at an even interval;

[0031] If the transport reference quantity of the effective supply factory is in a transport fluctuation condition, the feedback adjustment unit determines to perform graded delivery according to the supply capacity of each effective supply factory;

[0032] Among them, the transportation stability condition is that the reference distance stability meets the first preset stability range and the transportation capacity stability meets the standard, and the transportation fluctuation condition is that the reference distance stability meets the second preset stability range and / or the transportation capacity stability does not meet the standard.

[0033] Furthermore, the evenly spaced delivery includes: a feedback adjustment unit sets each effective supply factory to deliver concrete in ascending order of the shortest driving route length to the demand area, and a preset interval time range and a vehicle interval time range are provided, the delivery interval time of each delivery vehicle is set within the preset interval time range, and the interval difference between the arrival times of adjacent delivery vehicles is within the vehicle interval time range.

[0034] Furthermore, the hierarchical delivery includes: a feedback adjustment unit calculates supply characteristic parameters of each effective supply factory and classifies the corresponding effective supply factories according to the supply characteristic parameters, including a first effective supply factory and a second effective supply factory;

[0035] The feedback adjustment unit sets the first effective supply plant to deliver concrete in the order of the shortest driving route length to the demand area from small to large, and the second effective supply plant to deliver concrete in the order of the shortest driving route length to the demand area from small to large;

[0036] In a single supply cycle, the supply times of the first effective supply factory is once, and the supply times of the second effective supply factory is related to the supply characteristic parameters of the effective supply factory, and the supply characteristic parameters of the second effective supply factory are negatively correlated with the supply times;

[0037] The supply characteristic parameters of a single effective supply plant are related to the shortest travel route length between the effective supply plant and the demand area and the single transport allowance of the effective supply plant.

[0038] Furthermore, the feedback adjustment unit adjusts the vehicle interval time range according to the ambient temperature under the second feedback adjustment condition, and adjusts the preset interval time range according to the number of waiting vehicles.

[0039] The present invention also provides a management system using the management method for building materials in severe cold regions, which is characterized by comprising:

[0040] An interactive unit for inputting demand information;

[0041] a data analysis unit connected to the interaction unit, for determining the required number of supply plants according to the required concrete quantity of the demand area and determining the concrete production allocation method according to the number of supply plants within the selectable range of the demand area, including: determining the concrete production quantity of each optional plant according to the position coordinates of each optional plant when the number of optional plants meets the supply demand,

[0042] Or, when the number of optional plants meets the shortage of supply, the area of ​​the optional range is adjusted according to the number of optional plants to re-determine the concrete production allocation method;

[0045] The demand information includes the location coordinates of the demand area, the location coordinates of the supply plant, the required concrete quantity of the demand area, the single transport allowable quantity of the supply plant, and the ambient temperature.

[0046] Compared with the prior art, the beneficial effect of the present invention lies in that, when the number of optional factories meets the supply demand, the data analysis unit in the present invention determines the concrete production of each optional factory according to the location coordinates of each optional factory, or, when the number of optional factories meets the supply shortage, adjusts the area of ​​the selectable range according to the number of optional factories to re-determine the concrete production distribution method, so that the number of selected supply factories is more in line with the actual demand; and, the data analysis unit determines the concrete production of each effective supply factory according to the reference distance stability S, taking into account the influence of distance on the supply efficiency of the effective supply factory, so that the concrete production of each effective supply factory is more in line with the actual production demand.

[0047] Furthermore, the feedback regulation unit in the present invention determines the delivery method of each effective supply factory according to the transportation reference quantity of the effective supply factory under the first feedback regulation condition, so that the delivery method of the effective supply factory is more in line with the actual supply demand.

[0048] Furthermore, in the present invention, if the transportation reference quantity of the effective supply factory is in a transportation fluctuation condition, the feedback adjustment unit determines to carry out graded delivery according to the supply capacity of each effective supply factory. Taking into account that the vehicle carrying capacity of different factories is different, and therefore the single supply quantity is different, the factories with long transportation distances and small transportation volumes are extracted, thereby adopting different transportation methods for factories of different levels.

[0049] Furthermore, in the present invention, the delivery interval duration of each delivery vehicle is set within a preset interval duration range, and the interval difference between the arrival times of adjacent delivery vehicles is within a vehicle interval duration range, thereby avoiding the problem of vehicles waiting too long for unloading and waiting for pouring, thereby improving the transportation management efficiency of the ready-mixed concrete of the present invention.

[0058] See also Figures 1 to 3 As shown, the present invention provides a management method for building materials in severe cold regions, comprising:

[0059] S1, under the analysis trigger condition, the data analysis unit determines the required number of supply plants according to the required concrete quantity of the demand area and determines the concrete production allocation method according to the number of supply plants within the selectable range of the demand area;

[0060] S2, the data analysis unit extracts the location coordinates of the optional factories when the number of optional factories meets the supply demand state, eliminates invalid selected factories according to the distance from the demand area, and determines the concrete production volume of each effective supply factory according to the reference distance stability of the effective supply factory;

[0061] S3, when the number of optional factories meets the shortage state, the data analysis unit calculates the absolute value of the difference between the number of optional factories and the required number, and increases the area of ​​the optional range according to the reference difference to re-determine the concrete production allocation method;

[0062] S4, in response to the first feedback adjustment condition, the feedback adjustment unit determines the delivery method of each effective supply factory according to the transportation reference quantity of the effective supply factory, including that the delivery vehicles of each effective supply factory arrive at the demand area in sequence for uniform delivery and that the corresponding effective supply factory is graded according to the supply characteristic parameters of each effective supply factory and graded delivery with different transportation times;

[0063] S5, in response to the second feedback adjustment condition, the feedback adjustment unit performs adjustment determination of the vehicle interval time range and the preset interval time range;

[0064] Among them, the first feedback adjustment condition is that the effective supply factory is determined and completed, and the second feedback adjustment condition is that the delivery method of each effective supply factory is determined and completed.

[0065] Specifically, the data analysis unit determines the demand quantity of the supply plant according to the demand concrete quantity of the demand area under the analysis trigger condition;

[0066] The required amount of concrete is positively correlated with the demand quantity of the supply factory;

[0067] The analysis trigger condition is that the interaction unit inputs demand information.

[0068] Specifically, due to the large amount of foundation concrete pouring and the long construction time of large-scale projects, multiple factories are needed to supply it. Therefore, the required amount of concrete is positively correlated with the required number of supply factories to ensure that the number of supply factories meets the demand. However, it should be noted that the number of supply factories should be less than the preset maximum number. The value of the preset maximum number can be set by the user according to the actual application scenario, but it should be ensured that the required amount of concrete should be less than or equal to the preset maximum number × the minimum transportation volume. The minimum transportation volume is set according to the actual construction needs, that is, the minimum allowable amount that the transport vehicle can transport in a single time.

[0069] Specifically, the data analysis unit extracts supply factories within the selectable range of the demand area under the first data analysis condition, which is recorded as the number of optional factories, and determines the concrete production allocation method according to the number of optional factories, including: determining the concrete production volume of each optional factory according to the location coordinates of each optional factory when the number of optional factories meets the supply demand;

[0070] Or, when the number of optional plants meets the shortage of supply, the area of ​​the optional range is adjusted according to the number of optional plants to re-determine the concrete production allocation method;

[0071] Among them, the first data analysis condition is that the supply factory selection quantity is determined and completed.

[0072] Specifically, if the number of optional factories is greater than or equal to the required number, the supply demand state is met; if the number of optional factories is less than the required number, the supply demand state is not met.

[0073] Specifically, the data analysis unit extracts the location coordinates of the optional factories under the second data analysis condition, selects n optional factories in the order of the shortest driving route length to the demand area from small to large, and records them as effective supply factories, and records other optional factories as invalid selected factories and eliminates them. The data analysis unit calculates the reference distance stability S, and sets,

[0074]

[0075] Among them, Li is the shortest driving route length between the i-th effective supply factory and the demand area, n is the demand quantity;

[0076] The data analysis unit determines the concrete production of each effective supply plant according to the reference distance stability S, including:

[0077] When the reference distance stability meets the first preset stability range, the concrete production of each effective supply plant is set to be the same;

[0078] When the reference distance stability meets the second preset stability range, the corresponding concrete production volume is determined according to the shortest driving route length between each effective supply plant and the demand area;

[0079] Among them, the second data analysis condition is that the number of optional factories meets the supply demand status.

[0080] Specifically, the value of the preset stability range can be set by the user according to the actual application scenario. The smaller the reference distance stability, the closer the supply speed and supply distance of each effective supply plant are. A value is provided, and the values ​​within the first preset stability range are all greater than or equal to 0 and less than 20% of L0, and the values ​​within the second preset stability range are all greater than or equal to 20% of L0; when the reference distance stability meets the second preset stability range, the shortest driving route length between each effective supply plant and the demand area is negatively correlated with the concrete production volume. Due to the relatively long distance, the factors affecting the transportation time are more than those of the plants with shorter distances. Therefore, the concrete production distribution tasks are allocated in different proportions to reduce the impact of negative transportation factors on engineering efficiency.

[0081] Specifically, the data analysis unit calculates the absolute value of the difference between the number of optional factories and the required number under the third data analysis condition, and records it as a reference difference. The data analysis unit increases the area of ​​the selectable range according to the reference difference.

[0082] The reference difference value is positively correlated with the increase in the area of ​​the selectable range;

[0083] The third data analysis condition is that the number of optional factories satisfies the shortage of supply.

[0084] Specifically, the selectable range is a circular area, the center of the circle is the location coordinate of the demand area, and the initial radius is set by the user. When the area of ​​the selectable range is increased, the initial radius is increased. However, due to the condensable nature of concrete itself, the adjusted radius should be guaranteed to be less than 50km. If the number of optional factories within the adjusted selectable range is still less than the demanded number, the optional factories within the adjusted selectable range will be recorded as valid supply factories, and the judgment information will be transmitted to the display unit to issue a reminder message for manually setting the transportation method and transportation volume.

[0085] Specifically, the feedback adjustment unit determines the delivery method of each effective supply factory according to the transportation reference quantity of the effective supply factory under the first feedback adjustment condition;

[0086] If the transport reference quantity of the effective supply factory is in a stable transport condition, the feedback adjustment unit determines that each effective supply factory delivers at an even interval;

[0087] If the transport reference quantity of the effective supply factory is in a transport fluctuation condition, the feedback adjustment unit determines to perform graded delivery according to the supply capacity of each effective supply factory;

[0088] Among them, the transportation stability condition is that the reference distance stability meets the first preset stability range and the transportation capacity stability meets the standard, and the transportation fluctuation condition is that the reference distance stability meets the second preset stability range and / or the transportation capacity stability does not meet the standard.

[0089] Specifically, the calculation formula of transport capacity stability K is:

[0090] K=Kmax-Kmin

[0091] Specifically, Kmax is the maximum value among all supply characteristic parameters, and Kmin is the minimum value among all supply characteristic parameters;

[0092] The calculation formula for setting the supply characteristic parameter Ki of the i-th effective supply factory is:

[0093] Ki=(L0 / Li)×α1+(Mi / M0)×α2

[0094] Among them, Mi is the single transport allowable quantity of the i-th effective supply plant, M0 is the average value of the sum of all Mi, α1 is the first weight coefficient, α2 is the second weight coefficient, α1+α2=1, 0<α1<1, 0<α2<1, among which, the values ​​of α1 and α2 can be set by the user according to the requirements for the single transport allowable quantity and the shortest driving route length, and a value of α1 and α2 is provided, α1=α2=1, if K<0.5, it is recorded as the transport capacity stability meets the standard, and K>0.5, it is recorded as the transport capacity stability does not meet the standard.

[0095] Specifically, the evenly spaced delivery includes: a feedback adjustment unit sets each effective supply factory to deliver concrete in ascending order of the shortest driving route length to the demand area, and a preset interval time range and a vehicle interval time range are provided, and the delivery interval time of each delivery vehicle is set within the preset interval time range, that is, the interval time between two adjacent deliveries by a single delivery vehicle is within the preset interval time range, and the interval difference between the arrival times of adjacent delivery vehicles is within the vehicle interval time range, that is, the interval time of delivery vehicles arriving at the demand area in adjacent sequence is within the vehicle interval time range.

[0096] Evenly spaced delivery includes several single supply cycles, that is, each effective supply plant delivers concrete in ascending order of the shortest driving route length to the demand area, and when the transport vehicle of the last effective supply plant arrives, it is recorded as a single supply cycle, and the next single supply cycle is carried out again until the total amount of concrete delivered by each effective supply plant reaches the set concrete production volume.

[0097] Specifically, the hierarchical delivery includes: a feedback adjustment unit calculates supply characteristic parameters of each effective supply factory and classifies the corresponding effective supply factories according to the supply characteristic parameters, including a first effective supply factory and a second effective supply factory, wherein the supply characteristic parameter of the first effective supply factory is greater than or equal to 1, and the supply characteristic parameter of the second effective supply factory is less than 1;

[0098] The feedback adjustment unit sets the first effective supply plant to deliver concrete at even intervals, and the second effective supply plant delivers concrete in ascending order of the shortest driving route length to the demand area. In a single supply cycle, the supply times of the second effective supply plant are related to the supply characteristic parameters of the effective supply plant, and the supply characteristic parameters of the second effective supply plant are negatively correlated with the supply times.

[0099] The delivery time of the transport vehicle of the first effective supply factory is set to allow three delivery times of the transport vehicle of the second effective supply factory.

[0100] The supply characteristic parameters of a single effective supply plant are related to the shortest travel route length between the effective supply plant and the demand area and the single transport allowance of the effective supply plant.

[0101] Specifically, the feedback adjustment unit adjusts the vehicle interval time range according to the ambient temperature under the second feedback adjustment condition, and adjusts the preset interval time range according to the number of waiting vehicles.

[0102] The vehicle interval time range is [c1, c2], and the preset interval time range is [0, t1], wherein the values ​​of c2, c1 and c2 are determined according to the estimated delivery time of each effective supply factory, and the sum of the estimated delivery time of all effective supply factories is calculated, recorded as c0, c1=0.8×c0, c2=1.2×c0, and the value of t1 should be less than the maximum allowable interruption time of concrete pouring at the construction site. When adjusting the vehicle interval time range, only c2 is adjusted, and the ambient temperature is positively correlated with c2. When adjusting the preset interval time range, the number of waiting vehicles is positively correlated with t1. If the number of waiting vehicles is equal to 0, there is no need to adjust the preset interval time range. If the ambient temperature is greater than 5 degrees Celsius, there is no need to adjust the vehicle interval time range.

[0103] The display unit is respectively arranged at each supply factory to display the delivery sequence, concrete production volume and delivery time to the effective supply factory. The delivery time is determined according to the current time, the delivery sequence, the vehicle interval time range and the preset interval time range. This is easy to understand for those skilled in the art and will not be elaborated here.
