Detailed Description
The following description of the embodiments refers to the accompanying drawings.
Fig. 1 shows a control block diagram of an automatic start-stop control system of an excavator engine, which is used for automatic start-stop control when an excavator is in idle speed after being started in an operation cluster under the same working condition in the same area. The control system comprises a big data analysis platform 10, and the excavator comprises a data acquisition device which is used for acquiring the operation data of the excavator in real time and uploading the operation data to the big data analysis platform.
As shown in fig. 1, the overall controller obtains pressures of the main pump and the hydraulic actuator through a pressure sensor 28, obtains a temperature of hydraulic oil through a hydraulic oil temperature sensor 27, obtains a differential pressure of the post-processor through a post-processor differential pressure sensor 26, and obtains a state of a pilot lock 25.
The complete machine controller 20 also acquires engine operating data through the engine ECM21, and the engine ECM21 acquires the temperature of the coolant through the coolant temperature sensor 24 and the rotational speed of the engine through the rotational speed sensor 23.
The whole machine controller of each excavator uploads the collected operation data to the big data analysis platform 10 through the T-BOX22, and the big data analysis platform returns the analysis result to each target excavator.
The whole machine controller of the target excavator judges whether the whole machine controller meets the automatic stop condition of the engine stop operation or not according to the excavator operation data; and controlling the engine to automatically stop or keep running according to whether the target excavator meets the automatic stop condition and the idle speed occupation and pilot locking state of the machine group. The automatic start and stop control method of the excavator engine comprises the following specific steps:
as shown in fig. 2, step S1 includes substep S11 of collecting excavator operation data for uploading to the big data analysis platform and determining a target excavator and substep S12 of calculating a fleet idle ratio.
In step S11, the complete machine controller that has started the excavator in the cluster acquires the operation data of the complete machine through each sensor and uploads the operation data to the big data analysis platform, the big data analysis platform analyzes and determines the excavators operating under the same working condition in the same area according to the operation data uploaded by each excavator, and classifies the excavators operating under the same working condition in the same area as a target excavator.
The operation data uploaded to the big data platform by the excavator comprises model information, engine operation data used for determining the operation state of the excavator, positioning information used for determining the position of the excavator and working condition operation information used for determining the operation working condition of the excavator.
The model information is used to determine the size of the excavator operating capacity. In the same type of target excavator, the excavators are generally of the same model, that is, the respective excavators have the same work capacity. Excavators with different signals may also be present in the same type of target excavator.
The engine operation data is used for determining whether the excavator is in an idling operation state in a non-heat engine state, and the data mainly comprises engine rotating speed data, engine coolant temperature data and hydraulic oil temperature data. The engine coolant temperature data and the hydraulic oil temperature data are primarily used to determine whether the excavator is in a warm engine state.
The heat engine is a process of increasing the temperature of the engine and the temperature of hydraulic oil to predetermined temperatures after the engine is started, in which the engine is normally in an idle running state, but the temperature of the engine and the temperature of the hydraulic oil may continuously rise at night. When the engine runs at an idle speed and the temperature of the hydraulic oil and the temperature of the engine coolant continuously rise, the excavator can be judged to be in a heat engine state.
The positioning information is used to determine whether the excavators are located in the same area, such as the same work site. The positioning information is generally GPS information or Beidou positioning information, or information that the excavator is in a preset place can be determined through other positioning ways.
The working condition operation information is used for determining the working condition of the excavator, namely determining that the target excavator is in the same activity, such as excavating and loading operation. The operation condition can be determined in various ways, for example, a registration form is adopted, that is, a user registers and records an excavator performing certain operation on the large data platform, the excavator performing the operation of the corresponding condition only through the registration record, and when the large data platform receives the information of the excavator, the excavator is considered to perform the operation of the corresponding condition during the operation performed by the excavator.
The working condition can also be determined by collecting information about parameters related to the operation of the excavator, for example, by collecting pressure information of hydraulic actuators of the excavator working device, such as a boom cylinder, an arm cylinder, a bucket cylinder, a swing motor, etc., by using the pressure sensor 28, and by using the magnitude of the collected pressure and the time sequence of the pressure occurring in time. The excavator has corresponding actions when performing work under certain working conditions, for example, when performing excavation and loading work, one work cycle of the excavator sequentially comprises excavation action of a working device, extension and rotation action of an upper vehicle, unloading action of the working device and extension and rotation action of the upper vehicle. The operation of the excavator at the moment can be judged through continuous action of the whole excavator within a certain short time, and the operation within the preset time is counted, so that the operation working condition of the excavator within the time period can be judged.
In order to accurately judge the working condition of the excavator, on the basis of collecting pressure information of a hydraulic actuating piece of the excavator, other operation data can be collected and adopted, for example, one or more combinations of information such as engine load rate, engine rotating speed, engine torque, main pump pressure, accelerator gear, working mode and the like are collected, and comprehensive judgment is carried out.
And after the big data analysis platform determines the target excavator, performing a substep S12, and calculating the idle speed ratio of the excavator group performing the working condition operation in the region within a preset time period.
The idle ratio of the excavator group is the ratio of the total idle time and the total starting time of the excavator group performing the working condition operation in the region within the preset time, and the total idle time is the sum of the time when the excavator engine is in idle operation and the time when the engine automatically stalls according to the control method. Because the engine is also in idle speed operation during the heat engine, the heat engine duration is related to ambient temperature, and ambient temperature is high, and the heat engine time is short, and ambient temperature is low then the heat engine time is long, therefore the heat engine time has the length to have the weak point. In order to improve accuracy, the idle time of the excavator during heat engine is not counted into the counted total idle time when the total idle time is counted.
The total starting time length is the total time length after each excavator is started, the time length in the heat engine state and the time length for enabling the engine to automatically flameout according to the control method can be counted into the total starting time length or not.
The total idle time and the total start time are counted, an excavator which performs the working condition operation in the region within the preset time is taken as a counting object, the counted excavator can be the same type or different types, different weight coefficients can be set for different excavators, for example, an excavator with a 90-ton level in the region performs loading operation, an excavator with a 50-ton level also performs loading operation, if the weight coefficient of the excavator with a 90-ton level is set to be 1, the weight coefficient of the excavator with a 50-ton level can be set to be 0.5, that is, the operation capacity of two excavators with 50-ton levels is equivalent to the operation capacity of one excavator with 90 tons, and when the total idle time is counted, the idle time of one excavator with a 50-ton level is 1 minute is equivalent to the idle time of one excavator with 90 tons for 30 seconds.
And after the idle ratio of the cluster is calculated by the big data analysis platform, the idle ratio of the cluster is sent to each target excavator, or when the idle ratio of the cluster is greater than a preset value, the idle ratio of the cluster is sent to each target excavator.
Step S2: after the target excavator is started, the whole machine controller on the target excavator judges whether the target excavator meets the automatic stop condition of the engine stop operation or not according to the target excavator running data.
The automatic stop condition is that the engine is in an idle running state, the target excavator is in a non-heat engine state, and the exhaust gas aftertreatment device is not in a regeneration state.
The step of judging whether the target excavator is in the heat engine state comprises the steps of acquiring the temperature of hydraulic oil and the temperature of engine coolant, and judging that the target excavator is in the heat engine state when the engine runs in an idle speed and the temperature of the hydraulic oil and the temperature of the engine coolant continuously rise.
When the target excavator meets the automatic stop condition, the pilot locking state of the target excavator is detected, and the pilot locking needs to be unlocked when the target excavator operates.
When the target excavator meets the automatic stop condition, the sub-steps S21 and S22 are respectively executed in two cases, wherein one case is that the pilot lock is in a locked state, and the other case is that the pilot lock is in an unlocked state.
When the pilot lock is in the locked state, the stop information indicating whether the engine is off is displayed on the meter of the target shovel in substep S21. The operator can confirm the engine stop on the meter, or cancel the engine stop so that the engine still keeps normal operation. If the operator does not make a selection on the meter at the predetermined time, engine shutdown is performed by default. If the engine is automatically flamed out and stopped, the controller uploads the related data to the big data analysis platform, so that the big data analysis platform counts the time length of the engine after automatic flameout and stop when counting the total idle time length.
And if the target excavator meets the automatic stop condition and the pilot locking of the target excavator is in the unlocking state, performing a substep S22, namely comparing the idle speed ratio of the cluster, and if the idle speed ratio of the cluster is greater than a preset value, displaying stop information of whether the engine stalls on an instrument of the target excavator. At this time, the operator can confirm the engine stop on the meter (select command to stop) or cancel the engine stop (select command to keep running) so that the engine still keeps normal running. If the operator does not make a selection on the meter at the predetermined time, engine shutdown is performed by default. If the engine is automatically flamed out and stopped, the controller uploads the related data to the big data analysis platform, so that the big data analysis platform counts the time length of the engine after automatic flameout and stop when counting the total idle time length.
After the engine of the target excavator is automatically turned off, step S3 is performed, that is, the overall pilot operation signal is monitored, and if the operator manipulates the pilot operating device, such as a hand pilot or a foot pilot, to the excavator, and intends to make the excavator walk, turn or operate the working device, the overall controller may detect the overall pilot operation signal, and the overall controller sends an instruction for automatic start to the engine. The pilot operation signal of the whole machine can be an electric signal output when the electric control operation handle is operated, or a pilot pressure signal (the pilot pressure is larger than a preset value) on the pilot oil path is detected by a pressure sensor. After the engine is automatically started after the automatic flameout and shutdown, the whole machine controller uploads the related data to the big data analysis platform, so that the big data analysis platform counts the time length of the engine after the automatic flameout and shutdown when counting the total idle time length. In the invention, each excavator sends the running data to the big data analysis platform, the big data analysis platform analyzes the idle speed occupation ratio of the cluster as a reference of the busy degree of the whole cluster operation, and a proposal of whether to stop the excavator is given according to the idle speed occupation ratio when the engine of the excavator enters the idle speed state, thereby realizing further energy saving and facilitating the operation of an operator.
