As shown in fig. 1, the construction machine includes a chassis 100, a churn 200 and a chassis electrical device (not shown in fig. 1) disposed on the chassis 100, and a power system (not shown in fig. 1) for providing power to the chassis 100, the chassis electrical device and the churn 200, wherein, as shown in fig. 2, the power system includes: engine 300, power generation facility 400, running state detection device 700, and power battery 500; the power battery 500 is used for providing electric energy for the mixing drum 200, so that the mixing drum 200 can realize mixing work; engine 300 is used to provide kinetic energy to chassis 100 so that chassis 100 can travel under the driving of engine 300, and a driving state detection device 700, and controller 600, where driving state detection device 700 (not shown in fig. 1, shown in fig. 2) is used to detect driving state information of the construction machine. Engine 300, power generation facility 400, power battery 500, and running state detection device 700 are all electrically connected to controller 600. The power generation device 400 is connected between the engine 300 and the power battery 500, the engine 300 supplies kinetic energy to the power generation device 400, the power generation device 400 converts the kinetic energy into electric energy, and the power generation device 400 supplies the electric energy to the power battery 500 to charge the power battery 500. The controller 600 controls operations of the engine 300, the power generation device 400, and the power battery 500 according to the traveling state information of the construction machine, so that the movement of the chassis 100 and the operation of the mixing drum 200 in the construction machine are independent of each other.
Optionally, the work machine comprises a mixer truck.
As shown in fig. 3, the power control method of the construction machine includes the steps of:
step S101: acquiring driving state information of the engineering machinery;
wherein the driving state information includes:
(1) the work machine is stationary, i.e. the chassis 100 is not moving, but is stationary. When the engineering machinery is static, the mixing drum 200 may or may not work, for example, before the engineering machinery starts to go to a construction site, materials required for construction such as cement are in the mixing drum 200, and therefore, the mixing drum 200 is in a working state; when the engineering machine arrives at a construction site, the chassis 100 is static, and the mixing drum 200 is still in a working state.
(2) The information of the motion state of the construction machine, that is, the chassis 100 is moving, that is, the chassis 100 is running. In the motion process of the chassis 100, according to the road condition information, the motion state information of the engineering machine may further include: the information of the uphill running and the information of the downhill running of the engineering machinery. During the movement of the chassis 100, according to the movement state information, the engineering machine state information may further include: acceleration running information, deceleration running information, braking information, and the like.
Step S102: according to the running state information, chassis control information and mixer drum control information are generated, wherein the chassis control information is used for controlling whether the engine 300 provides kinetic energy for the chassis 100, and the mixer drum control information is used for controlling whether the power battery 500 provides electric energy for the mixer drum 200.
Wherein, when the engineering machine includes the upper motor, the upper motor is used for driving the operation of the mixing drum 200, therefore, when the control information of the mixing drum is to control the power battery 500 to provide electric energy for the mixing drum 200, the power battery 500 provides electric energy for the upper motor, drives the operation of the upper motor, and thus drives the operation of the mixing drum.
Step S102, according to the running state information of the chassis 100, chassis control information and mixing drum control information are generated to respectively control the power modes of the chassis 100 and the mixing drum 200, namely according to the running state of the chassis 100, the power driving modes of the mixing drum 200 and the chassis 100 are mutually independent, the power driving mode of the chassis 100 mainly depends on electric energy, and the driving mode of the chassis 100 mainly depends on the engine 300, so that the fuel consumption of engineering machinery is reduced, and the environmental pollution probability is reduced; and because the power driving mode of the mixing drum 200 mainly depends on electric energy, the engine 300 can not provide kinetic energy for the mixing drum 200 in the operation process of the engineering machinery, and when the engineering machinery is in an uphill motion state, the engine 300 provides kinetic energy for the chassis 100 in full force, so that the probability of insufficient power for the engineering machinery to climb the slope is reduced.
Specifically, the engineering machinery further comprises a charging interface, the charging interface is connected with the power battery 500, the power battery 500 can be charged with commercial power through the charging interface, and the path of the commercial power charging can include but is not limited to: fill electric pile. Before the engineering machinery departs to a construction site, the power battery 500 is fully charged by adopting a charging pile. So that the probability of the power battery 500 being short of charge can be reduced.
It should be noted that, when the power battery 500 is charged with the commercial power under certain conditions, for example, when the vehicle travels in the process of running through the charging pile, the commercial power may also be charged into the power battery 500, so that the flexibility of charging the commercial power into the power battery 500 is high.
In one possible implementation manner, as shown in fig. 4, step S102 (generating chassis control information and mixer drum control information according to the driving state information) specifically includes the following steps:
step S1021: when the running state information is the motion state information, first chassis control information and first mixing drum control information are generated, the first chassis control information is used for controlling the engine 300 to provide kinetic energy for the chassis 100, and the first mixing drum control information is used for controlling the power battery 500 to provide electric energy for the mixing drum 200. In the movement process of the engineering machinery, the chassis 100 moves under the driving of the engine 300, and the mixing drum 200 works under the driving of the power battery 500, so that the power driving modes of the mixing drum 200 and the chassis 100 are independent from each other, the power driving mode of the chassis 100 mainly depends on electric energy, and the driving mode of the chassis 100 mainly depends on the engine 300, so that the fuel consumption of the engineering machinery is reduced, and the environmental pollution probability is reduced; and because the power driving mode of the mixing drum 200 mainly depends on electric energy, the engine 300 can not provide kinetic energy for the mixing drum 200 in the operation process of the engineering machinery, and when the engineering machinery is in an uphill motion state, the engine 300 provides kinetic energy for the chassis 100 in full force, so that the probability of insufficient power for the engineering machinery to climb the slope is reduced.
In one possible implementation, as shown in fig. 5, when the motion state information is the downhill state information, after step S1021 (when the driving state information is the motion state information, the first chassis control information and the first mixer drum control information are generated), the power control method of the construction machine further includes the steps of:
step S103: first control information for controlling the power generating device 400 to charge the power battery 500 is generated based on the downhill state information.
That is, when the construction machine travels on a downhill section, at this time, the power required by the construction machine is relatively low, and therefore, at this time, the controller 600 generates the first control information, transmits the first control information to the power generation device 400, the power generation device 400 turns on the engine 300 under the control of the first control information, the engine 300 provides kinetic energy to the power generation device 400, the power generation device 400 converts the kinetic energy into electric energy, and transmits the electric energy to the power battery 500, that is, the power generation device 400 charges the power battery 500, so that the probability that the power battery 500 is out of power is reduced, the engine 300 and the power battery 500 are fully utilized, and further, the power driving manner of the mixing drum 200 and the power driving manner of the chassis 100 are independent.
Specifically, the driving state detection device 700 includes: angle sensor arranged on chassis 100
Or a gyroscope. The angle sensor and the gyroscope are used for detecting whether the chassis 100 is in a downhill state, that is, the angle sensor or the gyroscope detects an angular velocity of the chassis 100 in a movement process, and when the angular velocity meets a preset range, it is determined that the chassis 100 is in downhill operation according to the angular velocity, so that information of the downhill state is generated, and the information of the downhill state is transmitted to the controller 600, and the controller 600 generates first control information according to the information of the downhill state.
In one possible implementation manner, as shown in fig. 6, when the motion state information is the brake information, after step S1021 (when the driving state information is the motion state information, the first chassis control information and the first mixer drum control information are generated), the power control method for a construction machine further includes the steps of:
step S104: second control information for controlling the power generation device 400 to charge the power battery 500 is generated based on the braking information.
That is, when the construction machine is braked during traveling, at this time, the power required by the construction machine is relatively low, and therefore, at this time, the controller 600 generates second control information, transmits the second control information to the power generation device 400, the power generation device 400 switches on the engine 300 under the control of the second control information, the engine 300 provides kinetic energy for the power generation device 400, the power generation device 400 converts the kinetic energy into electric energy, and transmits the electric energy to the power battery 500, that is, the power generation device 400 charges the power battery 500, the probability that the power battery 500 is out of power is reduced, thereby fully utilizing the engine 300 and the power battery 500, and further enabling the power driving mode of the mixing drum 200 and the power driving mode of the chassis 100 to be independent.
Specifically, the driving state detection device 700 includes: when the brake switch is turned on, the brake switch is electrically connected to the brake device of the chassis 100, and when the brake device of the chassis 100 is turned on, that is, the chassis 100 is in a braking state, at this time, the brake switch generates first brake information and transmits the first brake information to the controller 600, and the controller 600 generates second control information according to the first brake information.
When the driving state detecting device 700 includes a brake indicator, the brake indicator is electrically connected to the brake device of the chassis 100, and when the brake device of the chassis 100 is activated, that is, the chassis 100 is in a brake state, at this time, the brake indicator generates second brake information and transmits the second brake information to the controller 600, and the controller 600 generates the second control information according to the second brake information.
The power control method of the construction machine shown in fig. 5 and 6 is: when the kinetic energy required by the chassis 100 is less than the preset kinetic energy during the movement of the engineering machine, 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 are both used for controlling the power generation device 400 to charge the power battery 500, and the concrete expression forms of the first control information and the second control information may be the same or different.
In one possible implementation manner, as shown in fig. 7, step S102 (generating chassis control information and mixer drum control information according to the driving state information) specifically includes the following steps:
step S1022: when the driving state information is the destination information, second chassis control information and second churn control information are generated, the second churn control information is used for controlling the power battery 500 to supply electric energy to the churn 200, and the second chassis control information is used for controlling the engine 300 to stop supplying kinetic energy to the chassis 100.
That is, when the engineering machine arrives at a construction site, the chassis 100 may be stopped, that is, the operation of the engine 300 is stopped, and the power battery 500 provides electric energy for the mixing drum 200, so that the mixing drum 200 may continue to operate, and at this time, the engine 300 is not required to provide kinetic energy for the mixing drum 200, thereby reducing fuel consumption and reducing the probability of environmental pollution.
Specifically, as shown in fig. 8 and 9, after step S1022, step S102 (generating chassis control information and mixer drum control information from the traveling state information) further includes the steps of:
step S1023: acquiring the working state information of the power battery 500;
that is, when the power battery 500 supplies power to the mixing drum 200, the power battery 500 may run out of power, that is, the power of the power battery 500 is insufficient, or the power battery 500 fails, at this time, the power battery 500 cannot supply power to the mixing drum 200 so as to operate the mixing drum 200, and since the mixing drum 200 requires power (electric power or kinetic energy) to drive the mixing drum 200 to operate during operation, the engine 300 is started to supply kinetic energy to the mixing drum 200 at this time. I.e. step S1024 or step S1025 is performed.
Step S1024: when the operating state information of the power battery 500 is the fault information, third control information is generated, and the third control information is used for controlling the generator to provide kinetic energy for the mixing drum 200, as shown in fig. 8. That is, when the power battery 500 fails and cannot continuously supply electric energy to the mixing drum 200, the engine 300 can supply kinetic energy to the mixing drum 200 at any time, thereby ensuring normal operation of the mixing drum 200.
Step S1025: when the working state of the power battery 500 is insufficient, fourth control information is generated, and the fourth control information is used for controlling the generator to provide kinetic energy for the mixing drum 200, as shown in fig. 9. That is, when the power battery 500 is not powered, the engine 300 can provide kinetic energy to the mixing drum 200 at any time, so that the mixing drum 200 can work normally.
Specifically, when the operating state of the power battery 500 is determined to be insufficient, the remaining power of the power battery 500 may be used to determine, for example, when the remaining power of the power battery 500 is less than or equal to the preset safe power, it may be determined that the operating state of the power battery 500 is insufficient. Due to the arrangement of the preset safe electric quantity, the buffer time for replacing the power source for the mixing drum 200 can be given, and the mixing drum 200 cannot stop working, so that the construction progress and the construction safety are influenced.
It should be noted that, not only when the power battery 500 is not powered after the construction machine arrives at the construction site, the engine 300 provides kinetic energy for the mixing drum 200, but also when the construction machine is in motion, if the power battery 500 is powered, the controller 600 still generates third control information according to the operating state information of the power battery 500, so as to control the engine 300 to provide kinetic energy for the mixing drum 200, thereby ensuring the normal operation of the mixing drum 200.
It should be noted that the third control information and the fourth control information both control the engine 300 to supply kinetic energy to the mixer drum 200, and the expression forms of the third control information and the fourth control information may be the same or different.
In a possible implementation manner, when the construction machine further includes a solar panel, after step S102, the power control method of the construction machine further includes the steps of:
step S103: and generating fifth control information according to the running state information of the engineering machinery, wherein the fifth control information is used for controlling the solar panel to charge the power battery 500. That is, the controller 600 controls the solar cell panel to charge the power battery 500 regardless of the movement state of the construction machine (for example, flat traveling, climbing traveling, downhill traveling, braking traveling, stationary traveling, etc.) during the operation of the construction machine. In this case, power battery 500 may not be charged using generator 400, or the amount of electricity that generator 400 charges power battery 500 is small, so that the load of engine 300 may be reduced. Fig. 10 is a schematic diagram illustrating an operation of a power controller of a construction machine according to the present application as a second aspect of the present application, and as shown in fig. 10, the power controller 600 of the construction machine includes: a driving state obtaining module 601, configured to obtain driving state information of the construction machine; a control information generating module 602, configured to generate chassis control information and churn control information, where the chassis control information is used to control whether the engine 300 provides kinetic energy for the chassis 100, and the churn control information is used to control whether the power battery 500 provides electric energy for the churn 200. That is, the controller 600 makes the power driving modes of the mixing drum 200 and the chassis 100 independent from each other according to the running state of the chassis 100, and the power driving mode of the mixing drum 200 mainly depends on electric energy, and the driving mode of the chassis 100 mainly depends on the engine 300, thereby reducing the fuel consumption of the engineering machinery and reducing the probability of environmental pollution; and because the power driving mode of the mixing drum 200 mainly depends on electric energy, the engine 300 can not provide kinetic energy for the mixing drum 200 in the operation process of the engineering machinery, and when the engineering machinery is in an uphill motion state, the engine 300 provides kinetic energy for the chassis 100 in full force, so that the probability of insufficient power for the engineering machinery to climb the slope is reduced.
As a third aspect of the present application, as shown in fig. 2, the present application provides a power system of a construction machine, for providing power for the construction machine, wherein the construction machine includes: a base plate 100 and a mixing drum 200 provided on the base plate 100; the power system of the construction machine includes: an engine 300, wherein the engine 300 is respectively connected with the chassis 100 and the mixing drum 200; the power generation device 400, the power generation device 400 is connected with the engine 300, and the power generation device 400 is used for converting kinetic energy provided by the engine 300 into electric energy; the power battery 500, the power battery 500 is connected with the mixing drum 200 and the power generation equipment 400; a traveling state detection device 700, the traveling state detection device 700 detecting a traveling state of the construction machine; and a controller 600, the controller 600 being electrically connected to the power battery 500, the power generation device 400, the engine 300, and the running state detection device 700, respectively; the structure of the controller 600 is the structure of the power controller 600 of the construction machine described above. The method for controlling the power of the construction machine by the controller 600 is the above-mentioned method for controlling the power of the construction machine, and will not be described herein again. No matter the engineering machinery is in the operation process, or the engineering machinery arrives after the construction site, or the power battery 500 breaks down, the power system of the engineering machinery provided by the application can reduce oil consumption and environmental pollution under the condition of ensuring that the chassis 100 and the mixing drum 200 work normally, so that power sources of the chassis 100 and the mixing drum 200 are mutually independent, and the probability of mutual restraint is further reduced. The power system of the engineering machinery is suitable for various application scenes of the engineering machinery.
Optionally, the work machine further includes a chassis electric device (not shown in fig. 1) disposed on the chassis 100, and then the power system further includes: the storage battery provides electric energy for the chassis electric equipment, so that the chassis electric equipment can normally work. Namely, the power system of the mixer truck also comprises a storage battery which is used for providing electric energy for other electric appliances on the mixer truck.
Specifically, the storage battery is used for providing electric energy for chassis electric equipment on the engineering machinery. Chassis power devices include, but are not limited to: indicator lights, signal lights, radios, air conditioners, central control screens, driving recorders, etc. Since the electric power required by the chassis electric equipment is small compared to the mixer drum 200, the power battery 500 and the storage battery are respectively used for the chassis electric equipment and the mixer drum 200, so that the probability that the chassis electric equipment cannot be normally displayed due to the power battery 500 being dead can be reduced, and the degree of association between the mixer drum 200 and the chassis electric equipment can be reduced.
Optionally, the storage battery may be a rechargeable storage battery, at this time, the controller 600 is further electrically connected to the storage battery, when the electric quantity in the storage battery is less than or equal to the preset electric storage quantity, the controller 600 may generate a storage battery control signal and transmit the storage battery control signal to the power generation device 400, and the power generation device 400 charges the storage battery. Since the amount of electricity required by the battery is small, the power generation device 400 charges the battery and does not share too much kinetic energy of the engine 300, so that the engine 300 can be charged while the chassis is normally operated no matter what motion state the construction machine is in (for example, traveling on flat ground, traveling on an uphill, traveling on a downhill, braking traveling, etc.).
It is understood that when the amount of electricity in the battery is less than or equal to the preset amount of electricity, and when the work machine is in a driving state of downhill driving, braking driving, the controller 600 may generate a battery control signal and transmit the battery control signal to the power generation device 400, and the power generation device 400 charges the battery.

Wherein, the sensor includes: an angle sensor or a gyroscope.
Specifically, the driving state detection device 700 further includes: the brake indicator lamp is electrically connected with the brake equipment and the controller 600 respectively; when the brake apparatus is actuated to brake, the brake indicator lamp generates second braking information and transmits the second braking information to the controller 600.
In a possible implementation manner, the power system of the engineering machine may further include a solar panel, and the solar panel is connected with the controller 600 and the power battery 500. The solar cell panel is used for converting solar energy into electric energy. During the whole working process of the construction machine, no matter what motion state the construction machine is (e.g., flat traveling, climbing traveling, downhill traveling, braking traveling, stationary, etc.), the controller 600 controls the solar cell panel to charge the power battery 500. In this case, power battery 500 may not be charged using generator 400, or the amount of electricity that generator 400 charges power battery 500 is small, so that the load of engine 300 may be reduced.
