[0002] Background of the Invention

[0003] Currently, concrete engineering machinery has been widely used in the field of construction engineering. The concrete engineering machinery drives the mixing drum on the construction machinery to rotate to achieve concrete mixing operations.

[0004] Currently, construction machinery is typically powered by diesel, which has low combustion efficiency and produces excessive emissions that are difficult to control. Existing construction machinery often uses a power take-off connected to the main engine to drive a hydraulic mechanism to power the mixing drum. However, the upper drive system of the construction machinery relies on the power provided by the main engine and cannot operate independently. When the construction machinery is stationary, the main engine cannot be shut down, resulting in increased fuel consumption, environmental pollution, and maintenance costs.

[0042] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0043] Figure 1 is a schematic structural diagram of an exemplary engineering machine of the present application; Figure 2 is a schematic working principle diagram of a power system of an exemplary engineering machine of the present application; Figure 3 is a flow chart of a control method of the controller 600 in the power system of the engineering machine shown in Figure 2 when controlling the power of the engineering machine. As shown in FIG1 , the construction machinery includes a chassis 100, a mixing drum 200 provided on the chassis 100, and chassis electrical equipment (not shown in FIG1 ), and a power system (not shown in FIG1 ) that provides power to the chassis 100, the chassis electrical equipment, and the mixing drum 200. As shown in FIG2 , the power system includes: an engine 300, a power generation device 400, a driving state detection device 700, a power battery 500, and a controller 600. The power battery 500 is used to provide electrical energy to the mixing drum 200, thereby enabling the mixing drum 200 to achieve a mixing operation. The engine 300 is used to provide kinetic energy to the chassis 100, so that the chassis 100 can travel under the drive of the engine 300. The driving state detection device 700 (not shown in FIG1 , shown in FIG2 ) is used to detect driving state information of the construction machinery. The engine 300, the power generation device 400, the power battery 500, and the driving state detection device 700 are all electrically connected to the controller 600. The power generation device 400 is connected between the engine 300 and the power battery 500. The engine 300 provides kinetic energy to the power generation device 400, which converts the kinetic energy into electrical energy. The power generation device 400 then supplies the electrical energy to the power battery 500, thereby charging the power battery 500. The controller 600 controls the operation of the engine 300, the power generation device 400, and the power battery 500 based on the driving status information of the construction machine, thereby making the movement of the chassis 100 and the operation of the mixing drum 200 in the construction machine independent of each other.

[0044] Optionally, the construction machinery includes a mixer truck.

[0045] As shown in FIG3 , the power control method for construction machinery includes the following steps:

[0046] Step S101: Acquire driving status information of the construction machinery;

[0047] The driving status information includes:

[0048] (1) Information about the construction machinery being stationary, i.e., the chassis 100 is not moving but is stationary. When the construction machinery is stationary, the mixing drum 200 may or may not be operating. For example, before the construction machinery leaves for the construction site, the mixing drum 200 is filled with cement and other materials needed for the construction, and therefore, the mixing drum 200 is in operation. When the construction machinery arrives at the construction site, the chassis 100 is stationary, and the mixing drum 200 is still in operation.

[0049] (2) Construction machinery motion state information, i.e., the chassis 100 is in motion, i.e., the chassis 100 is traveling. During the movement of the chassis 100, based on the road condition information, the construction machinery motion state information may also include: uphill driving information, downhill driving information, etc. During the movement of the chassis 100, based on the motion state information, the construction machinery motion state information may also include: acceleration information, deceleration information, braking information, etc.

[0050] Step S102: Generate chassis control information and mixing drum control information based on driving status information, wherein the chassis control information is used to control whether the engine 300 provides kinetic energy to the chassis 100 , and the mixing drum control information is used to control whether the power battery 500 provides electrical energy to the mixing drum 200 .

[0051] Among them, the engineering machinery can also include an upper motor, which is used to drive the operation of the mixing drum 200. Therefore, when the mixing drum control information is to control the power battery 500 to provide electrical energy to the mixing drum 200, the power battery 500 provides electrical energy to the upper motor to drive the operation of the upper motor, thereby driving the operation of the mixing drum.

[0052] Step S102 generates chassis control information and mixing drum control information according to the driving state information of the chassis 100 to control the power modes of the chassis 100 and the mixing drum 200 respectively, that is, the power modes of the chassis 100 and the mixing drum 200 are controlled according to the driving state of the chassis 100, so that the power drive modes of the mixing drum 200 and the chassis 100 are independent of each other, and the power drive mode of the mixing drum 200 mainly relies on electric energy, while the power drive mode of the chassis 100 mainly relies on the engine 300, thereby reducing the fuel consumption of the construction machinery and reducing the probability of environmental pollution; and since the power drive mode of the mixing drum 200 mainly relies on electric energy, therefore, during the operation of the construction machinery, the engine 300 will not provide kinetic energy for the mixing drum 200. When the construction machinery is in an uphill movement state, the engine 300 fully provides kinetic energy to the chassis 100, thereby reducing the probability of insufficient power for the construction machinery to climb.

[0053] Specifically, the construction machine also includes a charging port connected to the power battery 500. This port allows the power battery 500 to be charged with mains electricity. This charging port can be used, but is not limited to, via a charging station. Before the construction machine departs for the construction site, the power battery 500 is fully charged using the charging station. This reduces the likelihood of the power battery 500 running low on power.

[0054] It should be noted that when there are conditions for charging the power battery 500 with mains power, for example, when encountering a charging station during driving, the power battery 500 can also be charged with mains power. Therefore, charging the power battery 500 with mains power has high flexibility.

[0055] In one possible implementation, as shown in FIG4 , step S102 (generating chassis control information and mixing drum control information based on driving state information) specifically includes the following steps:

[0056] Step S1021: When the driving state information is motion state information, first chassis control information and first mixing drum control information are generated. The first chassis control information is used to control the engine 300 to provide kinetic energy for the chassis 100 , and the first mixing drum control information is used to control the power battery 500 to provide electrical energy for the mixing drum 200 . That is, during the movement of the engineering machinery, the chassis 100 moves under the drive of the engine 300, and the mixing drum 200 works under the drive of the power battery 500, so that the power drive modes of the mixing drum 200 and the chassis 100 are independent of each other, and the power drive mode of the mixing drum 200 mainly relies on electric energy, while the drive mode of the chassis 100 mainly relies on the engine 300, thereby reducing the fuel consumption of the engineering machinery and reducing the probability of environmental pollution; and since the power drive mode of the mixing drum 200 mainly relies on electric energy, therefore, during the operation of the engineering machinery, the engine 300 will not provide kinetic energy for the mixing drum 200. When the engineering machinery is in an uphill movement state, the engine 300 fully provides kinetic energy to the chassis 100, thereby reducing the probability of insufficient power for the engineering machinery to climb.

[0057] In one possible implementation, as shown in FIG5 , when the motion state information is downhill state information, after step S1021 (when the driving state information is motion state information, generating first chassis control information and first mixing drum control information), the power control method for construction machinery further includes the following steps:

[0058] Step S103 : generating first control information according to the downhill state information, where the first control information is used to control the power generation device 400 to charge the power battery 500 .

[0059] That is, when the construction machinery is traveling on a downhill section, the power required by the construction machinery is relatively low. Therefore, at this time, the controller 600 generates a first control information and transmits the first control information to the power generation equipment 400. The power generation equipment 400 connects to the engine 300 under the control of the first control information. The engine 300 provides kinetic energy to the power generation equipment 400. The power generation equipment 400 converts the kinetic energy into electrical energy and transmits the electrical energy to the power battery 500. That is, the power generation equipment 400 charges the power battery 500, reducing the probability of the power battery 500 being out of power, thereby making full use of the engine 300 and the power battery 500, and further making the power drive mode of the mixing drum 200 and the chassis 100 independent.

[0060] Specifically, the driving state detection device 700 includes an angle sensor or a gyroscope disposed on the chassis 100. The angle sensor or gyroscope can be used to detect whether the chassis 100 is in a downhill state. Specifically, the angle sensor or gyroscope detects the angular velocity of the chassis 100 during movement. When the angular velocity meets a preset range, the chassis 100 can be determined to be in a downhill state based on the angular velocity. Consequently, downhill state information is generated and transmitted to the controller 600. The controller 600 generates first control information based on the downhill state information.

[0061] In one possible implementation, as shown in FIG6 , when the motion state information is braking information, after step S1021 (when the driving state information is motion state information, generating first chassis control information and first mixing drum control information), the power control method for construction machinery further includes the following steps:

[0062] Step S104 : generating second control information according to the braking information, where the second control information is used to control the power generation device 400 to charge the power battery 500 .

[0063] That is, when the construction machinery brakes during driving, the power required by the construction machinery is relatively low. Therefore, at this time, the controller 600 generates a second control information and transmits the second control information to the power generation equipment 400. The power generation equipment 400 connects the engine 300 under the control of the second control information. The engine 300 provides kinetic energy to the power generation equipment 400. The power generation equipment 400 converts the kinetic energy into electrical energy and transmits the electrical energy to the power battery 500. That is, the power generation equipment 400 charges the power battery 500, reducing the probability of the power battery 500 being out of power, thereby making full use of the engine 300 and the power battery 500, and further making the power drive mode of the mixing drum 200 and the chassis 100 independent.

[0064] Specifically, when the driving state detection device 700 includes: a brake switch, the brake switch is electrically connected to the brake device of the chassis 100. When the brake device of the chassis 100 is activated, that is, the chassis 100 is in a braking state, at this time, the brake switch generates first braking information and transmits the first braking information to the controller 600. The controller 600 generates second control information based on the first braking information.

[0065] When the driving state detection device 700 includes a brake indicator light, the brake indicator light is electrically connected to the brake device of the chassis 100. When the brake device of the chassis 100 is activated, that is, the chassis 100 is in a braking state, the brake indicator light generates second braking information and transmits the second braking information to the controller 600. The controller 600 generates second control information based on the second braking information.

[0066] The power control methods for construction machinery shown in Figures 5 and 6 are both as follows: during the movement of the construction machinery, when the kinetic energy required by the chassis 100 is less than a preset kinetic energy, the controller 600 generates control information for controlling the power generation device 400 to charge the power battery 500. The first control information and the second control information both control the power generation device 400 to charge the power battery 500, and the specific forms of the first control information and the second control information may be the same or different.

[0067] In one possible implementation, as shown in FIG7 , step S102 (generating chassis control information and mixing drum control information according to driving state information) specifically includes the following steps:

[0068] Step S1022: When the driving status information is destination arrival information, second chassis control information and second mixing drum control information are generated. The second mixing drum control information is used to control the power battery 500 to provide electrical energy to the mixing drum 200 , and the second chassis control information is used to control the engine 300 to stop providing kinetic energy to the chassis 100 .

[0069] That is, when the construction machinery arrives at the construction site, the chassis 100 can be shut down, that is, the engine 300 can be stopped, and the power battery 500 provides electrical energy to the mixing drum 200, so that the mixing drum 200 can continue to work. At this time, the engine 300 is not needed to provide kinetic energy for the mixing drum 200, thereby reducing fuel consumption and the probability of environmental pollution.

[0070] Specifically, as shown in FIG8 and FIG9, after step S1022, step S102 (generating chassis control information and mixing drum control information according to driving state information) further includes the following steps:

[0071] Step S1023: Acquire the working status information of the power battery 500;

[0072] That is, when the power battery 500 provides power to the mixing drum 200, the power battery 500 may be exhausted, i.e., the power of the power battery 500 is insufficient, or the power battery 500 malfunctions. In this case, the power battery 500 cannot provide power to the mixing drum 200 to operate. Since the mixing drum 200 requires power (electrical energy or kinetic energy) to drive the mixing drum 200 during operation, the engine 300 is started to provide kinetic energy to the mixing drum 200. That is, step S1024 or step S1025 is executed.

[0073] Step S1024: When the operating status information of the power battery 500 indicates a fault, third control information is generated. The third control information is used to control the generator to provide kinetic energy to the mixer drum 200, as shown in FIG8 . That is, when the power battery 500 fails and is unable to continue to provide electrical energy to the mixer drum 200, the engine 300 can still provide kinetic energy to the mixer drum 200, thereby ensuring the normal operation of the mixer drum 200.

[0074] Step S1025: When the power battery 500 is in a low-power state, fourth control information is generated. The fourth control information is used to control the generator to provide kinetic energy to the mixer drum 200, as shown in FIG9 . That is, when the power battery 500 is out of power, the engine 300 can provide kinetic energy to the mixer drum 200 at any time, thereby enabling the mixer drum 200 to operate normally.

[0075] Specifically, the power battery 500 can be judged as being low on power by measuring its remaining charge. For example, if the remaining charge of the power battery 500 is less than or equal to a preset safety level, this indicates that the power battery 500 is low on power. This preset safety level provides the mixer drum 200 with time to change power sources, preventing the mixer drum 200 from stopping and impacting construction progress and safety.

[0076] It should be noted that not only when the power battery 500 is out of power after the construction machinery arrives at the construction site, the engine 300 provides kinetic energy for the mixing drum 200. When the construction machinery is in motion, if the power battery 500 is out of power, the controller 600 will still generate third control information based on the working status information of the power battery 500, which is used to control the engine 300 to provide kinetic energy for the mixing drum 200, thereby ensuring the normal operation of the mixing drum 200.

[0077] It should also be noted that the third control information and the fourth control information are both used to control the engine 300 to provide kinetic energy to the mixing drum 200 , and the third control information and the fourth control information may be expressed in the same or different forms.

[0078] In a possible implementation, when the construction machinery further includes a solar panel, after step S102, the power control method for the construction machinery further includes the following steps:

[0079] Step S103: Based on the driving state information of the construction machine, fifth control information is generated. This fifth control information is used to control the solar panel to charge the power battery 500. That is, during the operation of the construction machine, regardless of the machine's state (e.g., driving on flat ground, climbing a slope, driving downhill, braking, or stationary), the controller 600 controls the solar panel to charge the power battery 500. In this case, the generator 400 may not be used to charge the power battery 500, or the amount of electricity charged by the generator 400 to the power battery 500 may be small, thereby reducing the load on the engine 300. As the second aspect of the present application, Figure 10 is a working principle diagram of a power controller of an engineering machinery provided by the present application. As shown in Figure 10, the power controller 1000 of the engineering machinery includes: a driving status acquisition module 601, used to obtain driving status information of the engineering machinery; a control information generation module 602, used to generate chassis control information and mixing drum control information based on the driving status information, the chassis control information is used to control whether the engine 300 provides kinetic energy for the chassis 100, and the mixing drum control information is used to control whether the power battery 500 provides electrical energy for the mixing drum 200. That is, the power controller 1000 controls the power mode of the chassis 100 and the mixing drum 200 according to the driving state of the chassis 100, so that the power drive modes of the mixing drum 200 and the chassis 100 are independent of each other, and the power drive mode of the mixing drum 200 mainly relies on electric energy, while the drive mode of the chassis 100 mainly relies on the engine 300, thereby reducing the fuel consumption of the construction machinery and reducing the probability of environmental pollution; and since the power drive mode of the mixing drum 200 mainly relies on electric energy, during the operation of the construction machinery, the engine 300 will not provide kinetic energy for the mixing drum 200. When the construction machinery is in an uphill movement state, the engine 300 fully provides kinetic energy to the chassis 100, thereby reducing the probability of insufficient power for the construction machinery to climb.

[0080] As the third aspect of the present application, as shown in Figure 2, the present application provides a power system of engineering machinery for providing power for the engineering machinery, wherein the engineering machinery includes: a chassis 100 and a mixing drum 200 arranged on the chassis 100; the power system of the engineering machinery includes: an engine 300, the engine 300 is respectively connected to the chassis 100 and the mixing drum 200; a power generation device 400, the power generation device 400 is connected to the engine 300, and the power generation device 400 is used to convert the kinetic energy provided by the engine 300 into electrical energy; a power battery 500, the power battery 500 is connected to the mixing drum 200 and the power generation device 400; a driving state detection device 700, the driving state detection device 700 is used to detect the driving state of the engineering machinery; and a controller 600, the controller 600 is respectively electrically connected to the power battery 500, the power generation device 400, the engine 300 and the driving state detection device 700; wherein the structure of the controller 600 adopts the structure of the power controller 1000 of the engineering machinery described above. The controller 600 controls the power control method of the construction machinery as described above, and will not be described in detail here. Whether "during the operation of the construction machinery", "after the construction machinery arrives at the construction site", or "when the power battery 500 fails", the power system of the construction machinery provided in this application can reduce fuel consumption and environmental pollution while ensuring the normal operation of the chassis 100 and the mixing drum 200, making the power sources of the chassis 100 and the mixing drum 200 independent of each other, further reducing the probability of mutual restraint. In other words, the power system of the construction machinery provided in this application is suitable for a variety of application scenarios of construction machinery.

[0081] Optionally, the construction machinery further includes chassis electrical equipment (not shown in FIG1 ) mounted on the chassis 100 . In this case, the power system further includes a battery that provides electrical energy to the chassis electrical equipment, enabling the chassis electrical equipment to operate normally. In other words, the power system of the mixer truck further includes a battery that provides electrical energy to other electrical appliances on the mixer truck.

[0082] Specifically, the battery is used to provide power to the chassis electrical equipment on the construction machinery. Chassis electrical equipment includes, but is not limited to, indicator lights, signal lights, radios, air conditioners, central control screens, and driving recorders. Since these chassis electrical equipment require less power than the mixing drum 200, using a power battery 500 and a storage battery as the batteries for these chassis electrical equipment and the mixing drum 200, respectively, can reduce the probability of the chassis electrical equipment not displaying properly due to a dead power battery 500, and also reduce the correlation between the mixing drum 200 and these chassis electrical equipment.

[0083] Optionally, the battery can be a rechargeable battery. In this case, the controller 600 is also electrically connected to the battery. When the battery charge is less than or equal to a preset charge, the controller 600 can generate a battery control signal and transmit the battery control signal to the power generation device 400, which then charges the battery. Because the battery requires a relatively small amount of power, the power generation device 400 does not deplete the engine 300's kinetic energy. Therefore, regardless of the construction machine's state of motion (e.g., driving on flat ground, climbing a slope, driving downhill, braking, etc.), the engine 300 can maintain normal chassis operation while also charging the battery.

[0084] It can be understood that when the power in the battery is less than or equal to the preset power capacity, and when the construction machinery is in a downhill driving or braking driving state, the controller 600 can generate a battery control signal and transmit the battery control signal to the power generation equipment 400, and the power generation equipment 400 charges the battery.

[0085] Specifically, the driving state detection device 700 includes: a sensor arranged on the chassis 100, the sensor is used to detect whether the construction machinery is in a downhill driving state; and a brake switch, the brake switch is electrically connected to the brake device of the chassis 100, when the brake device is activated, the brake switch generates first braking information and transmits the first braking information to the controller 600.

[0086] The sensor includes an angle sensor or a gyroscope.

[0087] In another specific embodiment, the driving state detection device 700 further includes: a brake indicator light, which is electrically connected to the brake device and the controller 600 respectively; when the brake device is activated to brake, the brake indicator light generates a second braking information and transmits the second braking information to the controller 600.

[0088] In one possible implementation, the power system of the construction machinery may further include a solar panel, which is connected to the controller 600 and the power battery 500. The solar panel is used to convert solar energy into electrical energy. During the entire operation of the construction machinery, regardless of the state of motion of the construction machinery (e.g., driving on flat ground, climbing, driving downhill, braking, stationary, etc.), the controller 600 controls the solar panel to charge the power battery 500. In this case, the generator 400 may not be used to charge the power battery 500, or the amount of electricity charged by the generator 400 to the power battery 500 may be small, thereby reducing the load on the engine 300.
