step 100: and acquiring the working state of the engineering machinery.
The work state of the work machine may include a mobile work state and an in-place work state, wherein the mobile work state may include an uphill work state, a flat ground work state, and a downhill work state. When the engineering machinery is in a mobile working state and an original working state, the upper electric equipment and the chassis electric equipment of the engineering machinery can run and also stop running.
For example, when the engineering machinery is a mixer truck, the mixer truck can carry out mixing operation while moving in a moving working state, so that the working efficiency of the mixer truck is maximized; in the on-site operation, the mixer truck may be parked at the original or destination location, with power being provided only to the mixing apparatus. The mixer truck can be used for independently stirring without using an engine to provide kinetic energy for stirring equipment, so that the aim of reducing fuel consumption of the mixer truck is fulfilled.
Step 200: generating power supply information of electric equipment and power supply information of mobile equipment according to the working state of the engineering machinery; the power supply information of the electric equipment is used for indicating whether the upper battery provides electric energy for the upper electric equipment and the chassis electric equipment, and the power supply information of the mobile equipment is used for indicating whether the engine provides kinetic energy for the mobile equipment.
And generating different power supply information of the electric equipment and power supply information of the mobile equipment according to different working states of the engineering machinery. Wherein, the consumer includes facial make-up consumer and chassis consumer. The upper-mounted electric equipment comprises equipment used for executing work of the engineering machinery, such as a mixing drum and a speed reducer used for mixing materials on a mixing truck, and the chassis electric equipment comprises other electric equipment on the engineering equipment, such as a starting motor, an indicator light, a signal lamp, a radio, an air conditioner, a central control screen, a running recorder and the like. The moving equipment includes a chassis or the like for generating motion of the construction machine.
The power supply information of the electric equipment is used for indicating whether the upper battery provides electric energy for the upper electric equipment and the chassis electric equipment. The upper battery is simultaneously connected with the upper electric equipment and the chassis electric equipment, and the electric energy of the engineering equipment is provided by the upper battery; the mobile equipment power supply information indicates whether the engine provides kinetic energy for the mobile equipment, and the engine provides kinetic energy for the movement of the engineering equipment. Through two kinds of power supply information for the energy supply mode mutual independence of consumer and mobile device, and the power supply mode of consumer does not need to rely on the engine for the power supply of facial make-up battery, thereby has reduced the fuel consumption of engine, has reduced environmental pollution.
According to the power supply method of the engineering machinery, different power supply information of the electric equipment and power supply information of the mobile equipment are generated by obtaining the working state of the engineering machinery, the power supply information of the electric equipment and the power supply information of the mobile equipment are used for indicating the upper battery to provide electric energy for the upper electric equipment and the chassis electric equipment in the corresponding working state, and indicating the engine to provide kinetic energy for the mobile equipment in the corresponding working state. The power generation device can independently provide kinetic energy and electric energy for the engineering machinery, reduce the possibility of insufficient electric power or insufficient power generated by the engineering machinery, reduce the fuel consumption of an engine and reduce the environmental pollution. Only one set of upper battery is adopted to provide electric energy for the upper electric equipment and the chassis electric equipment, so that the cost can be reduced.
Fig. 3 is a schematic flow chart of a power supply method for a construction machine according to another exemplary embodiment of the present application, and as shown in fig. 3, the step 200 may include:
step 210: when the working state of the engineering machinery is a mobile working state, generating first power supply information of the electric equipment and first power supply information of the mobile equipment; the first mobile device power supply information is used for indicating the engine to provide kinetic energy for the mobile device.
When the engineering machinery is in a moving working state, the mobile equipment of the engineering machinery is in a working state, so that the power supply information of the first mobile equipment indicates the engine to provide kinetic energy for the mobile equipment when the engineering machinery moves. In the moving process of the engineering machinery, the upper electric equipment on the engineering machinery can be in a working state or an inoperative state, and the chassis electric equipment on the engineering machinery is in a working state. Therefore, the power supply information of the first electric equipment and the power supply information of the first mobile equipment respectively provide electric energy and kinetic energy, so that the driving modes of the electric equipment and the mobile equipment are independent from each other, and mutual interference and influence can not be caused.
For example, in the moving process of the construction machine, the mixer truck may select to use the mixing drum for mixing operation, or may select not to use the mixing drum and only transport the material in the mixing drum. The mixer truck needs to start a starting motor, which is a motor for starting the engine and needs to be driven by electricity, so that the mixer truck needs to provide independent power supply for chassis electric equipment such as the starting motor. The engine and the upper battery are controlled through different power supply information, fuel consumption of the engine is reduced, fault-tolerant probability of the engineering machinery can be improved, and when one energy supply device goes wrong, the other energy supply device cannot be influenced to continue to function.
Fig. 4 is a schematic flowchart of a power supply method for a construction machine according to another exemplary embodiment of the present disclosure, and as shown in fig. 4, after step 210, the power supply method for a construction machine may further include:
step 300: and generating first power supply information according to the mobile working state, wherein the first power supply information is used for indicating the solar power generation panel to charge the upper battery.
The upper battery is electrically connected with the solar power generation panel, and the solar power generation panel provides electric energy for the upper battery. When the engineering machinery is located outdoors, solar energy can be collected through the solar power generation panel, and the solar energy is converted into electric energy to charge the upper battery. According to the first power supply information, the solar power generation panel can transmit electric energy to the upper battery, and the electric energy consumed by the upper battery in the working process is supplemented. Solar energy is a clean renewable resource, and the solar energy can be used for supplying power, so that the resource is saved, and the environment is protected.
Fig. 5 is a flowchart illustrating a power supply method for a construction machine according to another exemplary embodiment of the present disclosure, where as shown in fig. 5, when the working condition of the construction machine is a downhill working condition, after step 210, the power supply method for a construction machine may further include:
step 400: and generating second power supply information according to the downhill working state, wherein the second power supply information is used for indicating the generator to charge the upper battery.
When in a downhill working state, a generator can be installed for the engineering machinery. The energy generated by the downhill braking is recovered through the generator and converted into electric energy to be supplied to the upper battery. The upper battery is supplemented with electric energy through other ways, and the effect of saving energy is achieved.
FIG. 6 is a schematic flow chart illustrating a method for powering a work machine according to another exemplary embodiment of the present disclosure, where the work machine further includes a generator powered by the engine, as shown in FIG. 6; after step 300, the power supply method for the construction machine may further include:
step 220: and acquiring the working state of the solar power generation panel.
Whether the solar power generation panel can normally capture and convert sunlight or not is detected, and whether the solar power generation panel can normally output electric energy to the upper battery or not is detected. The working state of the solar power generation panel influences the electric quantity energy storage of the upper battery, and the electric quantity energy storage of the upper battery influences the work of the upper electric equipment and the chassis electric equipment. Therefore, the subsequent energy supply conditions of the upper electric equipment and the chassis electric equipment can be determined by acquiring the working state of the solar power generation panel.
Step 230: and when the working state of the solar power generation panel is a fault state, generating third power supply information, wherein the third power supply information is used for indicating the generator to provide electric energy for the upper battery.
When the solar power generation panel breaks down, third power supply information is generated to serve as emergency information, and the third power supply information indicates the power generator to provide electric energy for the upper battery. The generator provides kinetic energy through the engine and provides electric energy to the upper battery, so that the risk of insufficient electric power of the upper battery is reduced, and stable electric energy supply is provided for the engineering machinery.
Fig. 7 is a flowchart illustrating a power supply method for a construction machine according to another exemplary embodiment of the present application, and as shown in fig. 7, after step 210, the power supply method for a construction machine may further include:
step 240: and acquiring the working state of the upper battery.
And acquiring the working state of the upper battery, including acquiring the current electric quantity condition of the upper battery. The electric quantity condition of the upper battery affects the working time of the upper electric equipment and the chassis electric equipment of the engineering machinery, and when the electric quantity of the upper battery is not enough to provide electric energy for the upper electric equipment, the working condition of the engineering machinery can be affected. For example, in the middle of the stirring, the electric quantity of the upper battery of the stirring truck is insufficient, and the stirring operation cannot be continued. According to the attribute of the stirring materials, some stirring works are stopped in the midway, so that the whole stirring work is possibly invalid, and the waste of the materials and the waste of electric energy are caused.
Step 250: and when the working state of the upper battery is the state of insufficient electric quantity, fourth power supply information is generated and used for indicating the generator to provide electric energy for the upper battery.
And when the electric energy converted by the solar power generation panel cannot complement the electric quantity of the upper battery, generating fourth power supply information to indicate the generator to provide the electric energy for the upper battery. The fourth power supply information is used as emergency information when the electric quantity of the upper battery is insufficient, the engine is adopted to provide kinetic energy for the generator, and then the generator converts the kinetic energy into electric energy to provide the electric energy for the upper battery.
Fig. 8 is a schematic flow chart of a power supply method for a construction machine according to another exemplary embodiment of the present application, and as shown in fig. 8, the step 200 may further include:
step 270: when the working state of the engineering machinery is the original working state, generating second electrical equipment power supply information and second mobile equipment power supply information; the power supply information of the second electrical equipment is used for indicating the upper battery to provide electric energy for the upper electrical equipment and the chassis electrical equipment, and the power supply information of the second mobile equipment is used for indicating the engine to stop providing kinetic energy for the mobile equipment.
When the working state of the engineering machinery is the original working state, the engineering machinery can stop the work of the engine, and only the upper battery is adopted to provide electric energy for the upper electric equipment and the chassis electric equipment. For example, the mixer truck is not moved in situ, but only the mixing drum is used for mixing, and the engine can be stopped to provide kinetic energy for the mobile equipment. The upper battery is independently used for supplying power to the mixing drum, so that the fuel consumption of the engine is reduced, and the possibility of environmental pollution is reduced.
It should be noted that, besides the solar power generation panel and the generator are adopted to supply power to the upper battery, the upper battery can be externally connected with the commercial power for charging. The solar power generation panel can be replaced by a solar charging lamp, the upper battery is charged in different ways, the possibility of insufficient power of the upper battery is reduced, and the working stability of the upper electric equipment and the chassis electric equipment is improved.
