Description

Technical Field

[0001] The present invention relates to the field of automation technology, and in particular to an intelligent scheduling method and system for concrete transport vehicles. Background Art

[0002] In modern construction projects, the scheduling and management of concrete trucks is a crucial part of the construction process. With the continuous expansion of construction project scale and the increase in engineering complexity, traditional concrete truck scheduling methods have become unable to meet the needs of real-time, accuracy, and efficiency. Currently, most concrete truck scheduling relies on manual operation or simple predetermined plans, resulting in low scheduling efficiency and difficulty in real-time monitoring and optimization of the transportation process. In addition, the transportation of concrete involves multiple factors, such as traffic conditions, weather changes, construction site progress and demand, etc. The real-time changes of these factors make traditional scheduling methods unable to respond flexibly, resulting in unstable concrete supply and even affecting construction progress and project quality.

[0003] In order to solve the above problems, the present invention proposes a concrete transport vehicle scheduling method and system based on intelligent scheduling; this method integrates advanced information technology, sensing technology, data analysis and artificial intelligence algorithms to monitor the location, status and construction needs of transport vehicles in real time, and dynamically adjust the scheduling plan according to real-time data to achieve efficient management and precise distribution of concrete transportation; by optimizing the scheduling algorithm, it is possible to minimize transportation costs, reduce empty load rates and improve resource utilization efficiency while ensuring construction progress, thereby improving the intelligence level of the overall concrete transportation system. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above problems existing in the prior art and greatly improve its technical effect on the basis of the original technology; the present invention provides an intelligent scheduling method for concrete transport vehicles, the method comprising:

[0005] Planned construction information of each construction site is collected, and a corresponding concrete consumption curve P(t) is formulated based on the planned construction information; wherein t is the time information corresponding to the planned construction information, and P(t) is the concrete consumption rate at the corresponding moment; the planned construction information of each construction site includes: time-related planned construction information of each construction site formulated based on the actual conditions of the construction site; formulating the corresponding concrete consumption curve based on the planned construction information includes: formulating the corresponding concrete consumption curve P(t) based on the amount of concrete consumed per second according to the planned construction information.

[0006] An information collection center is established, and the information collection center is used to collect information including: concrete consumption curve information corresponding to each construction site, unconsumed concrete information at each construction site, loading time information of the transport vehicle, unloading time information of the transport vehicle, time information required for the transport vehicle to travel from the mixing station to each construction site, and transport vehicle status information; the transport vehicle status information includes: position information and motion status information of the transport vehicle at the construction site, and the motion status information includes: loading status information, unloading status information, path information on the way to loading, path information on the way to unloading, and undivided labor status; the information collection center includes: a positioning system and various types of sensors, and the various types of sensors include: speed sensors, distance sensors, cameras, etc.

[0007] Establish a transport vehicle intelligent dispatching center, which is connected to the information collection center. By obtaining the information collected by the information collection center, the transport vehicles are intelligently dispatched to replenish concrete for each construction site in a timely manner. The steps of the transport vehicle intelligent dispatching center for intelligent dispatching of transport vehicles are as follows: a1 The transport vehicle intelligent dispatching center obtains the real-time status information of each construction site and each transport vehicle through the information collection center; a2 Calculate the maximum waiting time information of concrete demand for each construction site and the time information required for each concrete transport vehicle to transport concrete to each construction site, and sort the maximum waiting time information of concrete demand for each construction site from small to large as follows: t1, t2, ..., t i ,…t m , i represents the i-th construction site, m represents a total of m construction sites, t i Indicates the maximum waiting time information of concrete demand at the i-th construction site; sort the time information required for each concrete transport truck to transport concrete to each construction site from small to large: T 1i 、T 2i ,…T ji ,…T ni , j represents the jth concrete transport truck, n represents the total number of concrete transport trucks, T ji represents the time required for the jth concrete transport truck to transport concrete to the ith construction site; a3 always ensures t i >T ni And transport concrete to the i-th construction site based on the principle of shortest transportation time priority.

[0008] Specifically, the calculation method of the maximum waiting time for concrete demand at a construction site is as follows: If the construction site has not yet been constructed, the maximum waiting time for concrete demand at the corresponding construction site is T max =t 待工 , t 待工Refers to the time for the construction site to start waiting; if the construction site has already started, the maximum waiting time for the concrete demand at the construction site is T max =t 消耗 , t 消耗 is the time that the remaining concrete can be consumed at the corresponding construction site; t 消耗 The calculation method is: Among them, t 消耗 is the time that the remaining concrete can be consumed at the corresponding construction site, t 实时 The time recorded in real time by the intelligent dispatch center, that is, the current time, Q 混凝土 is the amount of remaining concrete at the corresponding construction site; according to the corresponding integral formula, from the current time t 实时 Integrate the concrete consumption curve P(t) until it reaches t 消耗 At the moment when the amount of concrete consumed is equal to the amount of remaining concrete, t 消耗 The maximum waiting time for concrete demand at the construction site.

[0009] Specifically, the method for obtaining the time information required for a concrete transport truck to transport concrete to each construction site is as follows: if the corresponding concrete transport truck is in a waiting state, the time required for the corresponding concrete transport truck to transport concrete to each construction site is: T ji =T1+T 装料 +T2, where T ji is the time required for the jth concrete transport truck to transport concrete to construction site i, T1 is the time required for the waiting concrete transport truck j to arrive at the mixing station, and T 装料 is the time required for the concrete transport truck to load the concrete, and T2 is the time required for the concrete transport truck j to transport the concrete to the construction site i after loading. If the corresponding concrete transport truck is in working state, the time required for the corresponding concrete transport truck to transport concrete to each construction site is: T ji =T jh +T′1+T 装料 +T2, and i≠h; where T jh Calculate T as the time required for the working transport vehicle j to transport the concrete to the construction site h. jh The method is the same as the formula corresponding to the concrete transport vehicle in the waiting state; T′1 is the time required for the transport vehicle j to transport concrete from the construction site h to the mixing station, T 装料 It refers to the time required for concrete transport truck j to load the materials, and T2 refers to the time required for concrete transport truck j to transport the materials to construction site i after loading.

[0010] Specifically, transporting concrete to the i-th construction site by giving priority to the shortest transportation time means: allocating concrete transport vehicles to each construction site by collective allocation; the collective allocation method is to select T 1i 、T 2i ,…T ji ,…T ni Middle T 1i The corresponding concrete transport truck is used as the alternative transport truck for the i-th construction site; if T 1i If the corresponding concrete transport truck has been selected as a backup transport truck by other construction sites, select T 2i The corresponding concrete transport truck is used as the alternative transport truck for the i-th construction site; if T 2i If the corresponding concrete transport truck has been selected as a backup transport truck by other construction sites, select T 3i The corresponding concrete transport truck is used as the alternative transport truck for the i-th construction site; the above rule is iterated until a transport truck that is not used as an alternative transport truck by other construction sites is obtained as the transport truck for the i-th construction site.

[0011] In addition, the present invention also provides an intelligent scheduling system for concrete transport vehicles, which is used to implement the above-mentioned intelligent scheduling method for concrete transport vehicles. The system includes: an information collection module, an information analysis module, and a transport vehicle intelligent scheduling module; the information collection module serves as the information collection center of the system, and is used to collect information including: concrete consumption curve information corresponding to each construction site, unconsumed concrete information at each construction site, transport vehicle loading time information, transport vehicle unloading time information, time information required for the transport vehicle to travel from the mixing plant to each construction site, and transport vehicle status information; the information analysis module is used to analyze the information collected by the information collection module and participate in calculating the maximum waiting time information for concrete demand at each construction site and the time information required for each concrete transport vehicle to transport concrete to each construction site; at the same time, a concrete transport vehicle is selected for the i-th construction site based on the principle of prioritizing the shortest transportation time; the transport vehicle intelligent scheduling module is used to schedule the concrete transport vehicle to transport concrete to the corresponding construction site based on the correspondence between the concrete transport vehicle and the construction site obtained by the information analysis module.
