[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0041] like Fig.17 As shown, a road engineering construction unmanned operation scheduling system includes a control platform, a vehicle management module, a work mode management module, a task management module, and a construction work module;

[0042] The control platform sends a signal to the vehicle management module to select the vehicle type.

[0044] It also includes a data management module for collecting data statistics from the task management module;

[0045] It also includes a system maintenance module, which is used to maintain the operational safety of each module.

[0046] The vehicle management module is used for vehicle type management, vehicle parameter management, vehicle coding management, fault diagnosis and vehicle maintenance.

[0048] Vehicle parameter management includes: vehicle size, weight, speed, fuel volume of fuel vehicles or battery life of electric vehicles, wheel size, and various vibration modes;

[0049] Vehicle coding management includes: vehicle ID code, vehicle location, vehicle status (whether it is currently running, engine speed, vehicle speed, roller speed, whether the roller is vibrating, tire pressure, oil temperature, coolant temperature, current mode, etc.), start-stop control;

[0050] Fault diagnosis and vehicle maintenance include vehicle self-inspection, regular maintenance reminders, and replacement and maintenance of key vehicle parts.

[0051] The working mode management module includes a debugging mode, and the debugging mode includes an unmanned operation mode, a paver-free mode, a remote control module, and a remote control mode.

[0052] The task management module is used to manage the input of task data, construction site environment, operator number input, corresponding construction personnel number, and weather status records on the construction day;

[0053] The operation task data includes: name, location, kilometers, length, width, total number of available vehicles, road surface requirements, and construction period;

[0054] The construction site environment includes soil quality, hardness, and humidity;

[0055] The construction work module includes a construction preparation module and a construction process model module;

[0056] The construction preparation module includes the preparation work for construction, which includes: establishment of construction map, power-on self-test of communication equipment, operator control of vehicle power-on, system control of vehicle self-test, and transmission of self-test data to the dispatching system cloud service storage, and the operator uses the operating platform to adjust the vehicle mode to remote control mode or remote control mode;

[0057] Construction map establishment: Use map collection terminals to collect points around the construction site, upload them to the dispatching system, and establish the construction map boundaries;

[0058] The communication equipment is powered on for self-test. The system includes two communication networks: 4G or 5G communication terminal and local radio base station. The 4G or 5G network is used as the main communication means and the radio communication is used as a redundant backup. When there is no 4G or 5G network at the construction site, the radio communication is used as the main communication means.

[0059] The operator controls the vehicle to power on, and the system controls the vehicle to self-check and transmit the self-check data to the dispatch system cloud service storage. If the self-check reports a fault, the dispatch system will feedback to the operator for repair, and the current vehicle will not be included in the operation management;

[0060] The operator uses the operating platform to adjust the vehicle mode to the remote control mode or the remote control mode, and the operator remotely controls the vehicle to the starting point of the work area.

[0061] The setting of construction tasks includes: determination of the starting point of the route, selection of the construction section, selection of the number of vehicles participating in the operation, setting of the order of vehicle entry, setting of the formation, setting of the construction operation length and the length of the construction section, setting of the width of the construction operation, setting of the margin width for the construction start method, setting of the overlap width of the construction track, selection of the construction stage, setting of the number of construction compaction passes, setting of the construction compaction speed, selection of the vibration mode of the construction vehicle, selection of the watering mode of the construction vehicle, and selection of the construction path mode;

[0062] The above parameters can be set automatically by the system or one by one by the operator.

[0063] In the case of one-way four-lane roads, the maximum length of the construction section shall not exceed one kilometer and the width shall not exceed 16 meters. The total construction length can be automatically allocated to multiple construction sections by the system, or the operator can define the construction sections;

[0064] The construction management module is used for construction control and process management, and executes the arranged construction processes and techniques.

[0065] The data management module is used for statistics on the completion of current tasks, construction efficiency, raw material consumption statistics, and construction optimization suggestions.

[0066] System maintenance module, which is used to maintain the security of the system;

[0067] Construction task settings:

[0068] a) Define the smallest unit formation unit, one paver, two rubber-wheeled rollers, one single-wheeled roller, and one double-wheeled roller. The paver-free mode can be set, with only rollers operating.

[0069] b) Define the maximum single construction section (area / size), with a length not exceeding one kilometer and a width not exceeding 16 meters (four lanes in one direction). The total construction length can be automatically allocated to multiple construction sections by the system, or the operator can define the construction sections;

[0070] c) The system allocates the number and type of vehicles involved in the construction according to the construction task volume, the current environment of the construction site, the available vehicles, and the construction process requirements;

[0071] d) The system determines the vehicle path, number of passes, track overlap width, speed of different vehicle types, whether watering is required, etc. for the current construction section based on the map, the type and number of participating vehicles, construction process requirements, construction site environment, etc.;

[0072] e) The system formulates the construction task of the current vehicle, such as path, speed, vibration mode, etc., based on the construction task volume, current construction site environment, construction process requirements, and current vehicle parameters and attributes.

[0073] f) The system adjusts the construction requirements in real time based on the actual construction status of the vehicle, such as speed, path, etc., and the assigned construction requirements;

[0074] g) Path mode, which includes edge turn, back and forth compaction, oblique translation, etc. The system issues instructions to the vehicle according to the construction process requirements;

[0075] h) During the construction process, the system controls the alternating operation of vehicles according to the vehicle status, endurance, availability, and whether there is a fault, and refuels and charges vehicles that have run out of fuel or are low on battery.

[0076] Double steel wheels and single steel wheels have 1+1+1 vibration combination forms (static pressure, weak vibration, strong vibration).

[0077] The vibration status of the front and rear wheels of the double steel wheels can be controlled separately.

[0078] like Fig.16 As shown, a method for scheduling unmanned operations in road engineering construction comprises the following steps:

[0079] S1. Determine the distance of this construction, and input the number, type and operation mode of the construction vehicles required for this distance into the control platform according to the distance of the construction;

[0080] S2. The control platform transmits the received information to the vehicle management module, which selects the type and quantity of construction vehicles and sends the selection result to the work mode management module;

[0081] S3, the working mode management module selects the operating mode according to the type of construction vehicle;

[0082] S4, the task management module receives the task issued by the control platform, sets the task parameters according to the issued task, and the construction work module performs preparation work according to the task parameters;

[0083] S5. After the construction work module is ready, it controls the construction vehicles to work.

[0084] The paving machine dispatching method is as follows:

[0085] 1. Construction work:

[0086] In the preparation stage, some preparation work needs to be done before the fleet construction:

[0087] First, the GPS base station is powered on in advance and ready.

[0088] Again, the fleet is powered on and automatically performs self-checks.

[0089] The driver then drives to the destination, or drives remotely.

[0090] 2. Construction preparation:

[0091] like Figure 1 and Figure 2 As shown, the fleet initialization preparation before formal construction:

[0092] Determine the construction technology for this time, determine the formation machine model according to the construction technology, and the formation is based on the initial formation, with the manned fleet arranged in front of the paver.

[0093] The formation is placed according to the formation rules and construction sequence required for this construction. As an automatic initialization mode, after the system is started, the vehicles will automatically start working and go on site one by one.

[0094] If the site preparation area is not sufficient, you can choose manual initialization mode:

[0095] like Figure 2 As shown, within the limited preparation section area, vehicles can be placed anywhere but cannot block the current construction vehicle from changing lanes. There is only one initialization position, the dotted box position. Before each vehicle enters the field according to the actual order, someone needs to drive the vehicle to the initialization position, and the vehicle will automatically enter the field.

[0096] In the above two initialization modes, during the process, the system will pop up prompts to assist the user, such as "Initialization failed", "Position violation, unable to initialize", "Please confirm that the xxx vehicle has been placed in the initialization position".

[0097] The tablet computer places a "start construction" button to notify the server on the paver to start recording GPS positioning points and generating paths. Or first use the "start construction" button.

[0098] 3. Create a task:

[0099] The user uses a tablet to create today's construction task information: task name, operator, weather, etc. Tasks can be saved and imported.

[0100] 4. Setting of construction tasks:

[0101] Use a tablet to configure construction tasks, which can be saved and imported, as well as recommended scene selections.

[0102] Construction task parameters include construction road surface related and formation related;

[0103] The parameters related to the construction pavement are:

[0104] Table 1

[0105]

[0106] The formation-related parameters are:

[0107] Table 2

[0108]

[0109] After all the above construction task parameters are configured, they can be saved / exported or imported.

[0110] After the configuration is completed, click "Submit" to enter the next operation page "Construction Information and Control"

[0111] Unmanned operation control and status page:

[0112] Construction control: start, pause, cancel tasks.

[0113] Start means starting the overall construction, Pause means stopping the entire fleet, and Cancel means canceling all tasks.

[0114] End control: waiting mode, finishing mode.

[0115] The waiting mode is when all vehicles have finished the last section of construction and are waiting at the starting point of the next section. During the waiting process, they cannot stop and need to move slowly and repeatedly until they can continue to work. (The reciprocating position is within the first straight line compaction range before the starting point of the next section)

[0116] The closing mode is the last section construction. If the second-to-last section has not started construction, it will be integrated with the last remaining section for construction, and a pop-up window will prompt "remaining sections are integrated for construction"; if the second-to-last section has started construction, the last remaining section will be constructed independently, and a pop-up window will prompt "remaining sections are constructed independently"; if the last independent section is less than 3 meters, a pop-up window will prompt "unable to be constructed without human intervention, please intervene manually"; progress preview: total progress preview (complete project progress), current task progress (progress for the day, finalized routine / current total mileage);

[0117] Real-time compaction values: Compaction sensor data for each vehicle is digitally displayed.

[0118] Compulsory control: The vibration and watering of each vehicle can be compulsorily controlled.

[0119] like Figure 3 As shown, in the initial pressure stage: the fleet implements automated construction according to the relevant configuration of the tablet computer construction task received and communicates with the paver server. After the vehicle initialization is completed and the construction is started, they will go on the field one by one and complete the construction of this stage.

[0120] like Figure 4 As shown, in the re-pressing phase, after the initial pressing phase begins, the vehicles of the initial pressing phase can enter the field and complete the construction of this phase in turn.

[0121] like Figure 5 As shown in the figure, after the final pressure stage begins, the initial pressure and the re-pressure advance one construction section in turn. According to the scheduling system strategy, it is ensured that the cross-domain construction of the two stages will not conflict or collide.

[0122] like Figure 6 As shown, the construction is completed and the entire operation can be repeated until the tablet computer clicks on the relevant end operation.

[0123] After the paver leaves, the vehicle stops near the paver exit.

[0124] Road roller construction process:

[0125] a. Construction track overlap, ensuring that the roller routes overlap each time;

[0126] b. Rolling passes: The roller rolls forward and backward along the same or similar wheel track once, which is called one rolling pass; all the passes are completed, which is called one pass. The rolling quantity is calculated in this way.

[0127] The number of rolling passes is when the roller rolls forward and back along the same or similar wheel track once each, which is called one rolling pass; when all the rolling passes are completed, it is called one pass.

[0128] The number of rolling passes refers to the number of times the roller goes back and forth to complete the rolling of all the road surfaces in the construction area. It can also be calculated by dividing the width of the construction area by (roller width - overlapping area) and then rounding up.

[0129] c. Joint treatment: There needs to be intersections between different construction areas. If there are more than two vehicles working on the same construction area, the joints also need to be treated. For example: 8m wide road, two vehicles each press 4.5m: the distribution plan is as follows Figure 7 As shown, the width of the above two seams can be configured through PAD (this type of configuration is hidden in "Advanced Mode" or "Debug Mode")

[0130] The allocation scheme is as follows Figure 7 , Figure 8 As shown, for joint treatment, different construction areas or sections need to be crossed, that is, joint connection;

[0131] The allocation scheme is as follows Fig. 9 , Fig.10 If more than two vehicles are working on the same construction area, the intersection also needs to handle the joints. For example, if there is an 8m wide road, two vehicles roll 4.5m each, and at the intersection of the joints, the two vehicles roll repeatedly.

[0132] The width of the above two joints can be configured through the operating platform. The joint processing method includes joint width, length, zigzag cross, smooth cross, etc.

[0133] like Fig.11 As shown, d. Vibration strategy, current vibration starting conditions: vehicle speed ≥ 0.5km / h responds to the vibration start command.

[0134] like Fig.12 As shown in e. Path strategy, the path in the stop area has a 1-meter drop (the drop is adjustable from 0 to 3 meters and can be configured through PAD. This type of configuration is hidden in "Advanced Mode" or "Debug Mode"), forming a sawtooth shape:

[0135] The path difference during construction can be used to place a road surface fault, that is, the previous construction section of the road surface and the current construction section of the road surface are connected in a zigzag shape, which can effectively avoid cracking or faulting of the road surface at the construction connection point, and at the same time facilitate the scheduling system to identify and calculate the construction path.

[0136] like Fig.13 As shown, a construction path is a complete construction process. In the figure, construction is from the right to the left. In actual situations, construction may also be from the left to the right.

[0137] like Fig.14 As shown, the second construction requires the vehicle to drive to the starting point and repeat the first path:

[0138] like Fig.15 As shown, the lane change adopts reverse straight driving and forward lane change. The lane change distance is confirmed by the optimal control through tests. The temporary lane change distance is 10m, which is greater than the minimum turning radius. When changing lanes, after the last compaction is completed, continue to reverse straight driving for a certain distance, and then change lanes forward to the starting position. The temporary lane change distance is 15m, which is greater than 1.5 times the turning radius.

[0139] A. Determination of the construction area, that is, determination of the boundaries: Construction roads are generally straight lines, oblique lines, C-shaped or S-shaped curves.

[0140] A1. Regular shape (straight line, oblique line), the map collection equipment collects the lines of the corner points around the construction area to form a closed area, and uploads it to the scheduling system to form a closed area, that is, the construction boundary;

[0141] A2. For irregular shapes (C-shaped and S-shaped curves), the mapping equipment collects the corner points of the construction area boundary. For curves, the two ends and the middle points of the curve are collected. One is to connect the corner points, and the other is to calculate the direction of the curve through the two ends and the middle points of the curve, so as to form a closed area, that is, the construction boundary;

[0142] B. Construction route planning

[0143] B1. First determine the starting point and starting method of construction, that is, the starting point and where to start (left or right?)

[0144] B2. Taking the right side as an example, when the closed construction area boundary is established, the scheduling system calculates the number of horizontal path lines allowed for construction in the construction area based on the construction area width, roller width, margin width, and overlap width. The last and second to last paths are allowed to partially overlap.

[0145] C. Formation construction path method

[0146] C1. For drop construction, the dispatching system defines the construction route lines as 1, 2, 3... N. The first roller first compacts along the first route, moves to the third route for compaction after completing one pass, and moves to the fifth route for compaction after completing one pass. At the same time, the second roller compacts along the second route. By analogy, the routes of the first roller are 1, 3, 5... N, and the routes of the second roller are 2, 4, 6... N. The dispatching system controls the routes, parking and waiting of the rollers in real time according to the progress of the rollers to avoid collisions and improve work efficiency until the compaction passes and compaction degree requirements are met. This method is more suitable when the width of the construction area of ​​the roller exceeds 3 times the width of the roller.

[0147] C2. Traversal construction, the scheduling system defines the construction route lines as 1, 2, 3... N. The first roller first compacts along the first route, moves to the second route for compaction after completing one pass, and moves to the third route for compaction after completing one pass, traversing all routes until the compaction passes and compaction degree requirements are met; since the rubber-wheeled, single-steel-wheeled, and double-steel-wheeled rollers work alternately during the construction process, and the width of the construction area is not too wide, this method is often used during the construction process.

[0148] D. Change line

[0149] D1. After the roller completes one round of compaction and returns to the starting point, the scheduling system plans the starting point of the next route in advance according to the determined construction path method, and then plans the best moving path from the current starting point to the next starting point, and sends it to the roller. The roller automatically drives to the next starting point according to the path and then starts working. When planning the next starting point, the scheduling system calculates the starting position of the next route based on the path method and the height difference requirements.

[0150] D2. After the roller completes all compaction passes, it returns to the starting point of the last route. The scheduling system plans a path from the current starting point to the parking point and sends it to the roller. The roller automatically drives to the parking point according to the path and stops.

[0151] E. Change

[0152] E1. When the roller completes the compaction number of times in the current operation phase and achieves the compaction target, the dispatching system arranges the rollers required to participate in the operation to enter the site according to the requirements of the next stage of construction tasks. If the re-compacting starts after the initial compaction is completed, the dispatching system will re-plan the compaction operation route and path method according to the process requirements, that is, the compaction number of times in the re-compacting phase, compaction requirements, operation machine type, operation width, margin width, repeated width and other parameter requirements.

[0153] Recommended parameters

[0154] Wheel track overlap:

[0155] Temporarily available range: 20cm~120cm (adjustable at pad end)

[0168]

[0169]

[0170] Unmanned operation control and status page:

[0171] Construction control: start, pause, cancel tasks.

[0172] Start means starting the overall construction, Pause means stopping the entire fleet, and Cancel means canceling all tasks.

[0173] End control: waiting mode, finishing mode.

[0174] The waiting mode is when all vehicles have finished the last section of construction and are waiting at the starting point of the next section. During the waiting process, they cannot stop and need to move slowly and repeatedly until they can continue to work. (The reciprocating position is within the first straight line compaction range before the starting point of the next section)

[0175] The finishing mode is the last section of the construction. If the second-to-last section has not started construction, it will be integrated with the last remaining section for construction, and a pop-up window will prompt "remaining sections are integrated for construction"; if the second-to-last section has started construction, the last remaining section will be constructed independently, and a pop-up window will prompt "remaining sections are constructed independently"; then if the construction of the last independent section is less than 3 meters, a pop-up window will prompt "unable to be constructed without human intervention, please intervene manually"
