All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes a power-taking control method, device, apparatus, medium, product, and storage medium of the present invention with reference to fig. 1 to 15.
In order to clearly illustrate the power-taking control method, the invention is described in a specific scene:
at present, a concrete pump truck mostly adopts a diesel engine to provide power for the running process, and an upper pumping part adopts the engine to drive a generator to generate power or utilizes three-phase alternating current on a construction site to provide power for pumping. A pure electric chassis is adopted by part of the pump truck to provide driving force for running, the pump body is driven by three-phase alternating current on a construction site to charge a power battery, and the power battery directly drives the pump truck to be loaded when power failure occurs.
Similarly, three-phase alternating current on a construction site is used for providing power for pumping and needs to be set before construction; when power is cut off, the power battery directly drives the pump truck to load, the power battery can last for a short time due to large power consumption in the pumping process, and pumping operation cannot be continued if the power cannot be recovered in a construction site. Moreover, the pump truck can only passively receive a power grid to supply power to the pump truck, and cannot actively take power based on the power consumption requirement of the pump truck.
The embodiment of the invention provides a power-taking control method which can be applied to intelligent terminals such as mobile phones, computers, tablets and the like, can also be applied to servers, and can also be applied to operation machinery. When the method is applied to the intelligent terminal, the power consumption requirement of the power receiving end is obtained through the intelligent terminal, and then the power supply end is controlled to supply power to the power receiving end based on the power consumption requirement; when the method is applied to the server, the power consumption requirement of the power receiving end is obtained through the server, and then the power supply end is controlled to supply power to the power receiving end based on the power consumption requirement; when the method is applied to the operation machine, if the operation machine is a third-party operation machine, the power consumption requirement of the power receiving end is obtained through the operation machine, then the power supply end is controlled to supply power for the power receiving end based on the power consumption requirement, and if the operation machine is the power receiving end, the power supply end is controlled to supply power for the power receiving end based on the power consumption requirement by obtaining the power consumption requirement of the operation machine.
Next, the method will be described by taking an example in which the method is applied to a working machine as a power receiving end, and a working machine will be described by taking a pump truck described in the above-described working scenario as an example. Since most of the pump truck and the mixer truck are used in cooperation, the power supply end will be described as an example of the mixer truck. Of course, the power supply terminal can also be a fixed power supply.
However, the description is only for illustrative purposes and is not intended to limit the scope of the present invention. The other descriptions in the embodiments of the present invention are also for illustration purposes, and are not intended to limit the scope of the present invention.
The specific implementation of the method is shown in fig. 1:
step 101, acquiring power consumption requirements.
The power consumption requirement is determined based on the residual power of the power receiving end and/or the working condition of the power receiving end.
Specifically, the residual capacity of the power receiving end is the residual capacity of the power battery of the power receiving end, and the working condition of the power receiving end is working condition data during operation of the power receiving end.
In a specific embodiment, before the power consumption requirement is acquired, the docking identifier is received, and based on the docking identifier, it is determined that the power receiving terminal and the power supply terminal complete docking, and the remaining power of the power supply terminal is acquired.
Specifically, the pump truck docks through interface and trucd mixer in advance when needs get the electricity to the trucd mixer, receives the butt joint sign that the trucd mixer sent, based on the butt joint sign, confirms that pump truck and trucd mixer accomplish the butt joint, locks pump truck and trucd mixer, avoids the unexpected interrupt of the in-process that discharges, and then acquires the residual capacity of trucd mixer.
Of course, after the pump truck is docked with the mixer truck through the docking buckle, the docking identification is sent to the mixer truck, so that the mixer truck determines that the pump truck and the mixer truck are docked completely.
In one specific embodiment, after acquiring the remaining power of the power supply terminal, judging whether the remaining power of the power supply terminal is greater than a first preset power value; when the residual electric quantity of the power supply end is judged to be larger than a first preset electric quantity value, executing a step of acquiring a power consumption requirement; and when the residual electric quantity of the power supply end is judged to be less than or equal to the first preset electric quantity value, sending a butt joint release identifier to the power supply end, and after confirming that the butt joint release identifier returned by the power supply end is received, releasing the butt joint between the power receiving end and the power supply end.
Specifically, after the residual electric quantity of the mixer truck is obtained, whether the residual electric quantity of the mixer truck is larger than a first preset electric quantity value is judged; when the residual electric quantity value of the mixer truck is judged to be larger than the first preset electric quantity value, executing the step of acquiring the power utilization requirement; and when the residual electric quantity of the mixer truck is judged to be less than or equal to the first preset electric quantity value, sending a butt joint removing identifier to the mixer truck, and after confirming that the butt joint removing identifier returned by the mixer truck is received, removing the butt joint between the pump truck and the mixer truck.
According to the invention, when the residual electric quantity of the power receiving end is determined to be enough, the butt joint of the power supply end and the power receiving end is realized so as to control the power supply end to supply power to the power receiving end, and the over discharge of the power supply end is avoided.
Specifically, if the pump truck receives power supply of a power grid, the power grid can directly provide power for pumping; the power grid can also be used for providing power for pumping and simultaneously supplying power for a power battery of the pump truck; the power grid can also be used for supplying power to the power battery of the pump truck, and the power battery of the pump truck is used for supplying power for pumping.
When the pump truck does not have a power grid to supply power to the pump truck, the power battery of the pump truck can be used for providing power for pumping, and the power battery of the mixer truck can be controlled to provide power for pumping and/or supply power to the power battery of the mixer truck.
When the power is supplied by controlling the agitating lorry, the power battery of the agitating lorry is controlled to provide power for pumping and/or supply power for the power battery of the agitating lorry; the electric quantity of the power battery of the mixer truck is not considered, and the power battery of the mixer truck is directly controlled to provide power for pumping and/or supply power for the power battery of the mixer truck.
