The following describes a work machine provided by the present invention with reference to fig. 1 to 2.
Fig. 1 is a schematic structural diagram of a working machine according to the present invention, as shown in fig. 1, which mainly includes, but is not limited to: the device comprises an electric control unit 1, a flow control system 2, a spraying control system 3, a dust detection system 4 and a spraying device 5.
Wherein the dust detection system 4 comprises at least one set of sensor arrays.
Under the condition that the current spraying state of the operation machine is automatic spraying, the electric control unit 1 determines the target spraying strength and the target spraying direction according to the dust detection information collected by the sensor array.
The flow control system 2 adjusts the current spraying intensity to be the target spraying intensity, and the spraying control system 3 adjusts the current spraying direction to be the target spraying direction, so that the spraying device 5 can automatically spray.
Alternatively, the working machine may be an excavator, a paver, a road roller, a milling machine, a heading machine, a coal mining machine, etc., and in order to clarify the specific structure and the working principle of the working machine provided in the present application, in the following embodiments, the excavator is taken as an example for illustration, which is not to be construed as a specific limitation to the scope of the present invention.
The Electronic Control Unit 1 (ECU) may be a device capable of performing data processing and data storage, such as an industrial personal computer or a traveling computer, and is a data processing center of the entire work machine.
First, the electronic control unit 1 can accurately determine the current spraying state of the working machine. Generally, the current spraying state mainly includes two different states of automatic spraying and manual spraying.
On the other hand, when the working machine is in the manual spray mode, the driver manually sets parameters such as the spray intensity and the spray direction.
The electric control unit 1 receives input of a user, sends related parameters manually set by the user to the flow control system 2 and the spraying control system 3 so as to achieve the purpose of controlling the booster water pump and the steering motor system, and adjusts the actual spraying strength of the spraying device by controlling the booster water pump; the actual spraying direction of the spraying device is adjusted by controlling the steering motor system.
On the other hand, when the working machine is in automatic spraying, the electronic control unit 1 automatically determines the target spraying strength and the target spraying direction of the working machine according to the received dust detection information.
The dust detection information may include dust distribution information, such as: dust orientation and dust concentration.
The electric control unit 1 calculates the target spraying intensity according to the dust concentration at the current moment. When the spraying intensity of the spraying device is at the target spraying intensity, the dust can be effectively removed under the condition of minimum water consumption.
The target spraying intensity is compared with the current spraying intensity (i.e. the spraying intensity of the spraying device at the current moment), and the booster water pump in the flow control system 2 is controlled according to the difference between the target spraying intensity and the current spraying intensity, so that the spraying intensity of the spraying device is adjusted to the target spraying intensity.
Correspondingly, the electronic control unit 1 calculates the target spraying direction according to the dust position at the current moment to realize targeted dust fall, namely, the region where the dust position is located is mainly sprayed, and equal-flow spraying is not needed to be carried out on all positions, so that the water consumption can be effectively saved, and the spraying effect is better.
Specifically, the steering motor system in the spray control system 3 may be controlled according to the position difference between the target spraying direction and the current spraying direction to adjust the direction of the spray header of the spraying device 5, so as to adjust the spraying direction of the spraying device to the target spraying direction.
It should be noted that the dust detection system 4 provided by the present invention mainly realizes the real-time collection of dust detection information through a sensor array.
The operation machine provided by the invention can automatically adjust the spraying strength and the spraying direction of the spraying device by collecting the dust detection information in the operation process in real time so as to remove dust in a targeted manner, effectively ensure the health of operation personnel, and achieve the purpose of saving water resources on the basis of ensuring the dust removal effect.
Based on the above description of the embodiments, as an alternative embodiment, the sensor array is composed of three dust detection sensors arranged in a delta shape.

The three dust detection sensors are arrayed in a regular triangle, wherein a first dust sensor is arranged right in front, a second dust sensor is positioned at the lower left of the first dust sensor, and a third dust sensor is positioned at the lower right of the first dust sensor.
Under the condition that the current spraying state of the operation machine is automatic spraying, the three dust detection sensors in the dust detection system 4 can collect the dust emission data collected by the dust detection sensors respectively and feed the dust emission data back to the electronic control unit 1, and the electronic control unit 1 can calculate the dust detection information according to the dust emission data collected by the three dust detection sensors and the installation position information of the three dust detection sensors.
In the method for determining the dust concentration based on the dust data of the three dust detection sensors, the dust concentration at the current time can be determined by calculating the arithmetic mean of the dust concentrations contained in the three dust data.
The principle of determining the dust orientation from the dust emission data of the three dust detection sensors is: if three dust detection sensors are respectively arranged in the upper, lower left and lower right directions, in a two-dimensional plane formed by the three points, if dust drifts from the right direction, the third dust sensor can preferentially detect dust, then the second dust sensor detects dust again, the time difference of the dust detected by the three dust sensors can be calculated through the electric control unit 1, the direction of a test source is judged, the target spraying direction is determined through the electric control unit 1, and a control command for controlling the spraying direction is given.
For example: the direction detected by the first dust detection sensor is taken as the Y-axis direction, and the coordinate of the direction is (0, Y)1) (ii) a Establishing a plane coordinate system by taking the direction of the second dust sensor and the direction of the third dust sensor as the X-axis direction, and respectively recording the coordinates of the second dust sensor and the third dust sensor as (X)20) and (X)3，0)。
Let the coordinate of the dust position to be determined be (X)0，Y0) Then, it can be known that:
first dust transferTime t when sensor senses dust1Comprises the following steps:
time t when the second dust sensor senses dust2Comprises the following steps:
time t when the third dust sensor senses dust3Comprises the following steps:
where V is the propagation velocity of the dust.
In conjunction with equations 1-3 above, the time difference between the detection of dust by each sensor (i.e., the time difference between the detection of dust by each sensor)t1、t2And t3The difference value of the positions of the dust and the dust can be calculated, and the position of the dust can be accurately positioned.
According to the operation machine provided by the invention, the three dust detection sensor arrays are arranged to form the sensor array, so that the sensor array is used for collecting dust detection information in real time and sending the dust detection information to the electronic control unit, the electronic control unit is used for quickly adjusting the spraying direction and the spraying strength in real time according to the actual distribution of dust, the testing device is simple, the response speed is high, the dust removal effect is more obvious, and the water consumption can be effectively saved.
Based on the content of the above embodiment, as an optional embodiment, in the case that the current spraying state of the working machine is automatic spraying, the electronic control unit 1 is further configured to control a spraying mode of the spraying device 5 according to the dust detection information; the spraying mode comprises a water spraying mode and an atomizing mode.
The working machine provided by the invention can adopt the following working modes:
after the operation machine starts to execute a work task, the electric control unit 1 is automatically started and is controlled by the electric control unit to respectively supply power to the flow control system 2, the spraying control system 3 and the dust detection system 4.
And collecting dust detection information by the dust detection system 4 according to a preset frequency, uploading the dust detection information to the electric control unit 1, determining the dust direction and the dust concentration by the electric control unit 1, and calculating the target spraying strength and the target spraying direction.
The electronic control unit 1 controls the spraying control system 3 to adjust the spraying direction of the spraying device 5 according to the target spraying direction and the current spraying direction; meanwhile, the electric control unit 1 controls the flow control system 2 to adjust the spraying intensity of the spraying device 5 according to the target spraying intensity and the current spraying intensity.
Meanwhile, the spraying mode of the spraying device 5 can be adjusted to a water spraying mode or an atomizing mode according to the dust concentration detected by the dust detection information.
Wherein, the water spraying mode is suitable for the conditions of larger dust concentration and serious pollution; the atomizing (spraying) mode is mainly used for keeping and inhibiting dust, and has high water resource utilization and utilization efficiency aiming at the conditions of small dust concentration and fine and slight dust pollution.
The mode of setting the spraying mode of the spraying device 5 can be realized by adjusting the diameter of the water outlet of the spraying head in the spraying device 5.
And continuously and iteratively executing the steps until the electric control unit 1 determines that the dust concentration is reduced to the minimum concentration threshold according to the dust detection information, and automatically closing the related spraying system (or closing the booster water pump and closing the water outlet valve of the water storage container) so as to achieve the purpose of saving water resources.
In general, when the current spraying state of the working machine is automatic spraying, the electronic control unit 1 automatically sets the spraying mode according to the dust detection information, but the spraying mode may be manually set by a driver.
According to the operation machine provided by the invention, the electric control unit can automatically adjust the spraying mode of the spraying device according to the dust detection information, so that the utilization rate of water resources is effectively improved.
