Fig. 1 is a schematic structural diagram of an exemplary construction machine of the present application; Fig. 2 is a working principle diagram of a power system of an exemplary construction machine of the present application; The flow chart of the control method when the controller 600 in the power system of the construction machine is shown is controlling the power of the construction machine. As shown in Figure 1, construction machinery comprises chassis 100, the mixer drum 200 that is arranged on chassis 100 and chassis electrical equipment (not shown in Figure 1), provides power for chassis 100, chassis electrical equipment and mixer drum 200 Power system (not shown in Figure 1), wherein, as shown in Figure 2, the power system includes: engine 300, power generation equipment 400, driving state detection device 700, power battery 500 and controller 600; wherein, power battery 500 is used It is used to provide electric energy for the mixing drum 200, so that the mixing drum 200 can realize the stirring work; the engine 300 is used to provide kinetic energy for the chassis 100, so that the chassis 100 can drive under the driving of the engine 300, and the driving state detection device 700 (not shown in FIG. 1 shown in Fig. 2) is used to detect the driving state information of construction machinery. The engine 300 , the power generation equipment 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 for the power generation device 400, the power generation device 400 converts the kinetic energy into electrical energy, and the power generation device 400 provides the power battery 500 with electric energy to charge the power battery 500. The controller 600 controls the operation of the engine 300 , the power generation device 400 and the power battery 500 according to the driving 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, construction machinery includes mixer trucks.

As shown in Fig. 3, the power control method of construction machinery includes the following steps:

Step S101: Obtain the driving state information of the construction machinery;

Among them, the driving status information includes:

(1) Static information of construction machinery, that is, the chassis 100 does not move, but is in a static state. When the engineering machinery is at rest, the mixing drum 200 can work or not work. For example, before the construction machinery starts to go to the construction site, there are materials needed for construction such as cement in the mixing drum 200. Therefore, the mixing drum 200 is in a working state; when the construction machinery When arriving at the construction site, the chassis 100 is still and the mixing drum 200 is still in working condition.

(2) Motion state information of construction machinery, that is, the chassis 100 is moving, that is, the chassis 100 is running. During the movement of the chassis 100 , according to the road condition information, the movement state information of the construction machinery may also include: uphill driving information, downhill driving information, etc. of the construction machinery. During the movement of the chassis 100, according to the movement state information, the movement state information of the construction machinery may also include: acceleration driving information, deceleration driving information, braking information and the like.

Step S102: Generate chassis control information and mixer control information according to the driving state information, wherein the chassis control information is used to control whether the engine 300 provides kinetic energy for the chassis 100, and the mixer control information is used to control whether the power battery 500 is the mixer 200 Provide electrical energy.

Wherein, construction machinery can also comprise top-mounted motor, and top-mounted motor is used for driving the work of mixing drum 200, therefore, when the control information of mixing drum is to control power battery 500 to provide electric energy for mixing drum 200, power battery 500 then provides electric energy for top-mounted motor , to drive the work of the upper body motor, thereby driving the work of the mixing drum.

Step S102 is to generate 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, to control the chassis 100 and the mixing drum 200 according to the driving state of the chassis 100 The power mode of the mixing drum 200 and the chassis 100 are independent of each other, and the power driving mode of the mixing drum 200 mainly relies on electric energy, while the power driving mode of the chassis 100 mainly relies on the engine 300, thereby reducing the fuel consumption of construction machinery , reducing the probability of environmental pollution; and because the power drive of the mixing drum 200 mainly relies on electric energy, the engine 300 will not provide kinetic energy for the mixing drum 200 during the operation of the construction machinery. When the construction machinery is in an uphill motion state, The engine 300 fully provides kinetic energy for the chassis 100, thereby reducing the probability of insufficient power for the construction machinery to climb hills.

Specifically, the construction machinery also includes a charging interface, which is connected to the power battery 500, through which the power battery 500 can be charged with commercial power, and the way of charging the commercial power may include but not limited to: charging piles. Before the construction machine departs to the construction site, the power battery 500 is fully charged by using the charging pile. Thereby, the probability that the power battery 500 is insufficient can be reduced.

It should be noted that when there are conditions to charge the power battery 500 with the city power, for example, when a charging pile is encountered during driving, the power battery 500 can also be charged with the city power. Therefore, the flexibility of charging the power battery 500 with the city power is relatively high. .

In a possible implementation, as shown in FIG. 4, step S102 (generating chassis control information and mixing drum control information according to the driving state information) specifically includes the following steps:

Step S1021: When the driving state information is motion state information, generate the first chassis control information and the first mixing drum control information, 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 To control the power battery 500 to provide electric energy for the mixing drum 200 . That is, during the movement of construction machinery, the chassis 100 moves under the drive 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 of each other, and the power of the mixing drum 200 The driving method mainly relies on electric energy, and the driving method of the chassis 100 mainly relies on the engine 300, thereby reducing the fuel consumption of construction machinery and reducing the probability of environmental pollution; During operation, the engine 300 does 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 for the chassis 100, thereby reducing the probability of insufficient power for the construction machinery to climb uphill.

In a possible implementation, as shown in FIG. 5, when the motion state information is the downhill state information, in step S1021 (when the driving state information is the motion state information, generate the first chassis control information and the first stirring cylinder control information), the power control method of construction machinery also includes the following steps:

Step S103: According to the downhill state information, generate first control information, the first control information is used to control the power generation equipment 400 to charge the power battery 500 .

That is, when the construction machine is running on a downhill section, the power required by the construction machine is relatively low. Therefore, at this time, the controller 600 generates the first control information and transmits the first control information to the power generation device 400. The power generation device 400 Under the control of the first control information, the engine 300 is turned on, 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 making full use of the engine 300 and the power battery 500 , and further making the power driving mode of the mixing drum 200 and the chassis 100 independent.

Specifically, the driving state detecting device 700 includes: an angle sensor or a gyroscope arranged on the chassis 100 . Both the angle sensor and the gyroscope can be used to detect whether the chassis 100 is in a downhill state, that is, the angle sensor or the gyroscope detects the angular velocity of the chassis 100 during motion, and when the angular velocity meets the preset range, it can be determined according to the angular velocity that the chassis 100 is in a downhill state. Therefore, the downhill state information will be generated, and the downhill state information will be transmitted to the controller 600, and the controller 600 will generate the first control information according to the downhill state information.

In a possible implementation, as shown in FIG. 6, when the motion state information is braking information, in step S1021 (when the driving state information is motion state information, generate the first chassis control information and the first mixing drum control information), the power control method of construction machinery also includes the following steps:

Step S104: Generate second control information according to the braking information, the second control information is used to control the power generation equipment 400 to charge the power battery 500 .

That is, when the construction machinery brakes during running, the power required by the construction machinery is relatively low at this time. Therefore, at this time, the controller 600 generates the second control information, and transmits the second control information to the power generation equipment 400. The power generation equipment 400 The engine 300 is turned on 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 electrical 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 making full use of the engine 300 and the power battery 500 , and further making the power driving mode of the mixing drum 200 and the chassis 100 independent.

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

When the driving state detection device 700 includes a brake indicator light, the brake indicator light is electrically connected to the brake equipment of the chassis 100. When the brake equipment of the chassis 100 is activated, that is, the chassis 100 is in the braking state. second braking information, and transmit the second braking information to the controller 600, and the controller 600 generates second control information according to the second braking information.

The power control methods of the construction machinery shown in Fig. 5 and Fig. 6 are: during the movement of the construction machinery, when the kinetic energy required by the chassis 100 is less than the preset kinetic energy, the controller 600 generates control information for controlling the power generation equipment 400 to be powered. Battery 500 charges. Both the first control information and the second control information control the power generating equipment 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.

In a possible implementation, as shown in FIG. 7, step S102 (generating chassis control information and mixing drum control information according to the driving state information) specifically includes the following steps:

Step S1022: When the driving state information is destination arrival information, generate second chassis control information and second mixing drum control information, the second mixing drum control information is used to control the power battery 500 to provide electric energy for the mixing drum 200, and the second chassis The control information is used to control the engine 300 to stop providing kinetic energy to the chassis 100 .

That is, when the construction machinery arrives at the construction site, the chassis 100 can be stopped, that is, the engine 300 is stopped, and the power battery 500 provides electric energy for the mixing drum 200, so that the mixing drum 200 can continue to work. At this time, the engine 300 is not required to be the mixer drum. 200 provides kinetic energy, thus reducing fuel consumption and reducing the probability of environmental pollution.

Specifically, as shown in FIG. 8 and FIG. 9, after step S1022, step S102 (generating chassis control information and mixing drum control information according to the driving state information) also includes the following steps:

Step S1023: Obtain the working status information of the power battery 500;

That is, when the power battery 500 provides electric energy for the mixing drum 200, the power battery 500 may be out of power, that is, the power battery 500 is insufficient, or the power battery 500 fails. At this time, the power battery 500 cannot provide electric energy for the mixing drum 200. To make the mixing drum 200 work, since the mixing drum 200 needs power (electric energy or kinetic energy) to drive the mixing drum 200 to work, the engine 300 is started to provide kinetic energy for the mixing drum 200 at this time. That is, step S1024 or step S1025 is executed.

Step S1024: When the working state information of the power battery 500 is failure information, generate third control information, the third control information is used to control the generator to provide kinetic energy for the mixing drum 200, as shown in FIG. 8 . That is, when the power battery 500 breaks down and cannot continue to provide electric energy for the mixing drum 200 , the engine 300 can provide kinetic energy for the mixing drum 200 at any time, thereby ensuring the normal operation of the mixing drum 200 .

Step S1025: When the working state of the power battery 500 is insufficient power, generate fourth control information, the fourth control information is used to control the generator to provide kinetic energy for the mixing drum 200, as shown in FIG. 9 . That is, when the power battery 500 is out of power, the engine 300 can provide kinetic energy for the mixing drum 200 at any time, so that the mixing drum 200 can work normally.

Specifically, when it is judged that the working state of the power battery 500 is insufficient power, it can be judged by the remaining power of the power battery 500. For example, when the remaining power of the power battery 500 is less than or equal to the preset safe power, it can indicate The working state is insufficient power. Due to the setting of the preset safe power, the mixing drum 200 can be given a buffer time to replace the power source, and the mixing drum 200 will not stop working, which will affect the construction progress and construction safety.

It should be noted that not only when the power battery 500 is out of power after the construction machine arrives at the construction site, the engine 300 provides kinetic energy for the mixing drum 200, but also when the power battery 500 is out of power when the construction machine is in motion, the controller 600 will still The third control information will be generated according to the working state information of the power battery 500, and used to control the engine 300 to provide kinetic energy for the mixing drum 200, so as to ensure the normal operation of the mixing drum 200.

It should also be noted that the above-mentioned third control information and fourth control information both control the engine 300 to provide kinetic energy for the mixing drum 200 , and the expressions of the third control information and the fourth control information may be the same or different.

In a possible implementation manner, when the engineering machinery further includes solar panels, after step S102, the power control method of the engineering machinery further includes the following steps:

Step S103: Generate fifth control information according to the driving state information of the construction machine, and the fifth control information is used to control the solar panel to charge the power battery 500 . That is, during the working process of the construction machinery, no matter what kind of motion state the construction machinery is in (such as driving on flat ground, climbing a slope, driving downhill, braking, standing still, etc.), the controller 600 controls the solar panel to be the power battery 500 Charge. In this case, the generator 400 may not be used to charge the power battery 500 , or the power of the generator 400 to charge the power battery 500 is small, thereby reducing the load of the engine 300 . As the second aspect of the present application, Fig. 10 shows a working principle diagram of a power controller of construction machinery provided by the present application. As shown in Fig. 10, the power controller 1000 of the construction machinery includes: acquisition of driving state The module 601 is used to obtain the driving state information of the construction machinery; the control information generation module 602 is used to generate chassis control information and mixing drum control information according to the driving state information, and the chassis control information is used to control whether the engine 300 is the chassis 100 Kinetic energy is provided, 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 driving modes of the mixing drum 200 and the chassis 100 are independent of each other, and the power driving mode of the mixing drum 200 mainly relies on electric energy. The driving mode of the chassis 100 mainly depends on the engine 300, thereby reducing the fuel consumption of the construction machinery and reducing the probability of environmental pollution; Kinetic energy is not provided for the mixing drum 200 , and when the construction machine is in an uphill movement state, the engine 300 fully provides kinetic energy for the chassis 100 , thereby reducing the probability of insufficient climbing power of the construction machine.
