Further details of the operation of the auxiliary power control system 1022 are described below in connection with the method embodiments, and are not described in detail herein. In the embodiment of the present invention, the auxiliary generator is taken as a diesel generator as an example, and in practical application, the auxiliary generator may be another type of generator such as a gasoline generator, which is not limited to this.
Specifically, the engineering machine may be an engineering machine powered by an engine, such as a crane, an excavator, etc., and in the embodiment of the present invention, the engineering machine body 101 may be an engineering machine powered by diesel oil, such as a general automobile crane, an all-terrain crane, an off-road crane, a crawler crane, etc., the auxiliary power supply system provided by the embodiment of the present invention is used for supplying power to facilities of an operation room of the engineering machine, such as an audio-visual system, an air conditioning system, etc., and the auxiliary power supply control system 1022 may be implemented by a control chip having a calculation processing function, such as a single chip microcomputer, an MCU, etc., which is merely an example, and the present invention is not limited thereto.

According to an embodiment of the present invention, there is provided a method for auxiliary power supply of a construction machine, it being noted that the steps illustrated in the flowcharts of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order different from that herein.
In this embodiment, an auxiliary power supply method for an engineering machine is provided, which is applied to an auxiliary power supply control system 1022 shown in fig. 1, and is as follows: fig. 3 is a flowchart of an auxiliary power supply method of engineering machinery according to an embodiment of the present invention, as shown in fig. 3, the flowchart includes the following steps:
step S301, after receiving an auxiliary power supply command, controlling the auxiliary power generator to supply power to the construction machine, where the auxiliary power supply command is from an operation of an operation component of the construction machine by a user or from a response of the user to an auxiliary power supply request of the construction machine.
In particular, the auxiliary power supply instruction may be generated by a user operation, such as generating the auxiliary power supply instruction upon receiving a power supply switching operation by the user. For example, an operation member such as a power supply switching button or an operation lever may be provided in an operation area of the construction machine in the operation room, so that when the user actively desires to supply power to the auxiliary generator of the diesel generator, the manual power supply switching is performed by manually operating the operation member, and the limitation of the operation state of the engine is not limited. Therefore, a user can manually control power supply switching according to the driving operation requirement of the actual engineering machinery, the flexibility of power supply switching is improved, and the use experience of the user is further improved.
In addition, the auxiliary power supply command may also be automatically generated by monitoring the engine speed and/or the tank level of the engineering machine, and the specific process is described in detail in the following embodiments, which will not be described in detail herein.
In this embodiment, an auxiliary power supply method for an engineering machine is provided, which is applied to an auxiliary power supply control system 1022 shown in fig. 1, and is as follows: fig. 4 is a flowchart of an auxiliary power supply method of engineering machinery according to an embodiment of the present invention, as shown in fig. 4, the flowchart includes the following steps:
in step S401, the engine speed of the construction machine is monitored.
Specifically, the implemented rotational speed of the engine may be detected by providing a rotational speed detection device on the engine.
Step S402, determining a current working state of the construction machine based on the engine speed.
Wherein, the operating condition includes: an active state and an inactive state.
Step S403 generates a first auxiliary power supply request based on the current operating state.
Specifically, the first auxiliary power supply request is an example of an auxiliary power supply request for providing to a manipulator of the crane, so as to facilitate confirmation by the manipulator. For example, the operation confirmation can be provided for the user by popping up a confirmation interface for switching auxiliary power supply on the engineering machinery operation page.
Step S404, in response to the confirmation operation of the user on the first auxiliary power supply request, an auxiliary power supply instruction is generated.
The user can click the confirmation switch through the confirmation interface popped up on the engineering machinery operation page, namely the engineering machinery can be triggered to be switched from the engine power supply to the auxiliary generator power supply.
Step S405, when receiving an auxiliary power supply command, switches the power supply of the construction machine from the engine to the auxiliary generator.
The engine rotating speed of the engineering machinery is monitored to determine the actual working state of the engineering machinery, an auxiliary power supply request is triggered according to the actual working state, and after the user confirms, an auxiliary power supply instruction is generated to switch the engineering machinery to the diesel engine for auxiliary power supply, so that the excessive consumption of the engine service life and the fuel is avoided, the basic power consumption requirement of a control room when the user operates the engineering machinery can be met, and the user experience is improved.
In addition, the process of monitoring the rotation speed of the engine to determine whether to switch to the auxiliary power supply system may be as follows. When the rotating speed of the engine is lower than N1 in a certain continuous time, judging that the crane is in a non-working time, at the moment, sending an instruction of whether to switch the auxiliary power supply system to supply power to the crane control system, and judging whether to switch the auxiliary power supply system by an operator according to the actual operation condition of the site; if the engine rotating speed is monitored to be higher than N2 in a certain continuous time, judging that the crane is in working time, and directly switching to the combined power supply of the engine power supply and the auxiliary power supply system at the moment; when the rotation speed of the engine is detected to be higher than N3, the auxiliary power supply system stops supplying power, and the engine supplies power independently, wherein N1 is smaller than N2 and smaller than N3.
In this embodiment, another flow of the auxiliary power supply method of the construction machine is provided, which is applied to the auxiliary power supply control system 1022 shown in fig. 1, for example: single chip microcomputer, MCU, etc. Fig. 5 is another flowchart of a method of auxiliary power supply for a construction machine according to an embodiment of the present invention. As shown in fig. 5, the process includes the steps of:
in step S501, the engine speed of the construction machine is monitored. Details refer to the description of step S401 shown in fig. 4, and will not be described here again.
Step S502, determining a current working state of the construction machine based on the engine speed.
Specifically, the step S502 includes:
in step S5021, when it is detected that the current rotational speed of the engine is lower than the first preset rotational speed, timing is started.
The first preset rotating speed is the lowest rotating speed of the engine when the working machine executes the action command in the normal working process, and once the rotating speed of the engine is lower than the lowest rotating speed, the working machine does not execute the working action.
In step S5022, if the engine speed is not monitored to be not lower than the first preset speed in the process that the timing duration reaches the preset time threshold, the current working state of the engineering machine is determined to be a non-working state.
The preset time threshold is the longest interval time of two adjacent action instructions of the engineering machinery in the actual use process, for example: and executing the next telescopic boom instruction at the longest interval time of 3min after the whole crane rotates, and taking the longest interval time of 3min as a preset time threshold. It can be understood that the preset time threshold can be flexibly set according to the actual operation habit of the operator and the actual auxiliary power supply control precision requirement of the engineering machinery, and the invention is not limited thereto. When the rotation speed of the engine is always lower than the rotation speed for executing the action instruction within the preset time threshold, the engineering machine is in a standby state currently, and the actual operation is not performed.
Step S5023, if the engine speed is not lower than the first preset speed when the timing duration does not reach the preset time threshold, determining that the current working state of the engineering machine is the working state, and returning to step S501 after the timing is cleared.
When the engine speed is lower than the set value, the timing is triggered, and when the engine speed is continuously lower than the set value within a certain time, the engineering machinery is considered to be in a non-working state of suspending operation, otherwise, the engineering machinery can be considered to be in a continuous operation process, so that the working state of the engineering machinery can be accurately judged, and whether auxiliary power supply intervention is needed or not is conveniently determined.
Step S503 generates a first auxiliary power supply request based on the current operating state.
Specifically, the step S503 includes:
in step S5031, when the current operating state of the construction machine is a non-operating state, a first auxiliary power supply request is generated.
When the engineering machinery is in a non-working state, in order to reduce unnecessary consumption of an engine and fuel oil, an auxiliary power supply request is automatically generated, and a trigger condition is provided for the subsequent implementation of auxiliary power supply of the engineering machinery.
Step S504, in response to the confirmation operation of the user on the first auxiliary power supply request, an auxiliary power supply instruction is generated. Details refer to the description of step S404 shown in fig. 4, and will not be described here again.
In step S505, when the current working state of the working machine is the working state, the liquid level of the oil tank of the working machine is monitored.
Specifically, the diesel oil level of the diesel oil tank can be monitored in real time by arranging liquid level detection equipment such as a liquid level sensor in the diesel oil tank of the engineering machinery.
Step S506, judging whether the liquid level is lower than a first preset liquid level.
The first preset liquid level is the lowest liquid level for representing and maintaining the working state of the engineering machinery. When the liquid level of the diesel oil is not lower than the liquid level, the engineering machinery can work normally; when the diesel oil liquid level is lower than the liquid level, the residual diesel oil of the engineering machinery cannot normally maintain working, i.e. the hoisting operation cannot be normally performed, but the crane running requirement (set according to the working position and the refueling distance) is met. The operator can stop the lifting operation and drive by oneself to refuel, also can switch to auxiliary power supply system according to the actual operation condition in the scene, waits to refuel.
In step S507, when the liquid level is lower than the first preset liquid level, a second auxiliary power supply request is generated.
Specifically, the second auxiliary power supply request is another example of an auxiliary power supply request. In addition, the user can be reminded to timely refuel or wait for refuelling by displaying a fuel tank liquid level alarm display icon (yellow).
Step S508, generating an auxiliary power supply instruction in response to the confirmation operation of the user on the second auxiliary power supply request.
Through monitoring the oil tank liquid level, in case when monitoring the liquid level that the oil tank liquid level does not satisfy the action demand and corresponds, trigger supplementary power supply request to remind the operative employee to carry out supplementary power supply and switch and generate supplementary power supply instruction, ensure that diesel can satisfy the running demand of engineering machine, the basic power consumption demand of control room, remind the user in time to refuel simultaneously, further promote user's use experience.
Step S509, after responding to the confirmation operation of the user to the second auxiliary power supply request, judges whether the liquid level is lower than the second preset liquid level.
The second preset liquid level is lower than the first preset liquid level, and in practical application, the second preset liquid level is the lowest liquid level for guaranteeing the running requirement of the engineering machinery, and the second preset liquid level can be set according to the distance between the operation position and the refueling place.
And S510, when the liquid level is lower than a second preset liquid level, alarming for insufficient oil quantity is carried out.
Specifically, the oil shortage warning can be given out by displaying an oil tank liquid level warning display icon (red), making a sound or lighting light so as to prompt that the oil is shortage, the requirements of crane lifting and running operation cannot be met, and a user is reminded to wait for oiling.
Through the monitoring to the oil tank liquid level, can in time remind the user to the user carries out the selection of corresponding operation, further promotes user's use experience.
In step S511, when the auxiliary power supply command is received, the power supply of the construction machine is switched from the engine power supply to the auxiliary generator power supply. Details refer to the description of step S405 shown in fig. 4, and will not be described here again.
In addition, when the liquid level of the oil tank is detected to be higher than the first preset liquid level, the alarm display of the liquid level of the oil tank disappears, and at the moment, the liquid level meets the operation (lifting) requirement and the running requirement of the engineering machinery, and an operator can judge whether to switch to the auxiliary power supply system according to the actual operation condition.
The two judging modes based on the oil tank liquid level and the engine speed can be combined according to the requirement, and the invention is not limited to the two judging modes.
In this embodiment, an auxiliary power supply method for an engineering machine is provided, which is applied to an auxiliary power supply control system 1022 shown in fig. 1, and is as follows: fig. 6 is another flowchart of an auxiliary power supply method for engineering machinery according to an embodiment of the present invention, as shown in fig. 6, the flowchart includes the following steps:
in step S601, the liquid level of the oil tank of the construction machine is monitored. Details refer to the description of step S505 shown in fig. 5, and will not be described here again.
Step S602, judging whether the liquid level is lower than a first preset liquid level, wherein the first preset liquid level is the lowest liquid level for representing and maintaining the working state of the engineering machinery. Details refer to the description of step S506 shown in fig. 5, and will not be described here again.
In step S603, when the liquid level is lower than the first preset liquid level, a second auxiliary power supply request is generated. Details refer to the description of step S507 shown in fig. 5, and will not be described here again.
In step S604, an auxiliary power supply instruction is generated in response to a confirmation operation of the user on the second auxiliary power supply request. Details refer to the description of step S508 shown in fig. 5, and will not be described here again.
Step S605, when receiving the auxiliary power supply command, switches the power supply of the construction machine from the engine to the auxiliary generator. Details refer to the description of step S511 shown in fig. 5, and will not be described here again.
In step S606, when the construction machine is powered by the auxiliary generator, the engine of the construction machine is controlled to stop, and the operation of the construction machine in response to the user is stopped.
Specifically, when the engineering machinery is powered by the auxiliary power generator, if the user operates the crane to advance or execute the operation action at the moment, the user operation instructions are not responded, so that the power supply burden of the auxiliary power supply system is avoided being increased, in addition, the user can be synchronously prompted to switch the power supply mode to supply power for the engine, and the user is responded to the related operation instructions after switching back to the power supply of the engine.
Therefore, in the process of replacing the engine by the auxiliary generator to supply power to the engineering machinery, the engine of the engineering machinery is controlled to stop and the operation of a user is not responded, so that the problem that the operation experience of the user is insufficient to the engineering machinery operation, the operation efficiency and the service life of the engineering machinery are affected is avoided, and the safety operation performance of the engineering machinery is further improved.
In practical application, after the crane manipulator sees the auxiliary power supply request, whether the crane manipulator is switched to the auxiliary power supply system can be judged according to the field working condition. Because the system can be powered off after the engine is stopped, a certain time is needed for restarting the engine until the crane is in a working state, from the safety point of view, the system is not recommended to be directly switched to an auxiliary power supply system for supplying power from the engine power supply state, the engine and the auxiliary generator can be used for supplying power together, then the power supply capacity of the auxiliary generator is gradually increased, and meanwhile, the running power of the engine is reduced until the engine is stopped, and the invention is not limited by the method.
