Example one
The intelligent warning method provided by the embodiment is shown in the flow diagram provided in fig. 1, and includes the following steps:
s100, acquiring the intensity of the environmental sound;
s110, acquiring a preset alarm volume according to the environment sound intensity, wherein the sound intensity corresponding to the preset alarm volume is greater than the environment sound intensity;
s120, adjusting the volume of the alarm loudspeaker to a preset alarm volume;
s130, judging whether the engineering vehicle starts to generate a preset action or not;
and S140, if the engineering vehicle starts to perform the preset action, making an alarm loudspeaker sound.
The environmental sound intensity refers to the average volume intensity of the working environment of the engineering vehicle and can be calibrated by a metering unit decibel. The warning speaker 3 generally has warning sounds at a plurality of volume levels, and the predetermined warning volume is a volume level corresponding to the sound to be emitted from the warning speaker 3.
Optionally, the alarm speaker 3 is an existing volume adjustable alarm speaker. Specifically, the alert mode of the alert speaker 3 may be selected as needed. Further, the alarm speaker 3 may be an alarm speaker included in an existing audible and visual alarm.
The alarm loudspeaker 3 is triggered only when the engineering vehicle starts to perform the preset action, so that surrounding workers or other vehicles are reminded to pay attention to the fact that the engineering vehicle is about to perform the preset action, and construction danger is avoided.
In the intelligent warning method in the embodiment, before the warning speaker 3 gives an alarm, the volume of the warning speaker 3 is adjusted to the preset warning volume, so that the sound intensity corresponding to the preset warning volume is greater than the environmental sound intensity, and therefore, when the engineering vehicle starts to perform the preset action, the sound emitted by the warning speaker 3 can just adapt to the environmental sound intensity, the warning sound source is prevented from being covered by the noise of the surrounding environment, and the visibility and the effectiveness of the warning effect are improved.
In an alternative of this embodiment, the predetermined alert volume corresponds to a sound intensity that is greater than the predetermined intensity of the ambient sound intensity.
By limiting the preset intensity, the warning sound source is not only prevented from being covered by noise of the surrounding environment, but also the warning sound source is prevented from becoming a noise source instead of being too large under the condition that the intensity of the environmental sound is small. That is to say, can adjust the warning sound source to can enough guarantee warning effect and avoid too noisy degree again.
In an alternative of this embodiment, as shown in the flow diagram provided in fig. 2, the intelligent warning method includes the following steps:
s200, acquiring the intensity of the environmental sound;
s210, acquiring a preset alarm volume according to the environment sound intensity, wherein the sound intensity corresponding to the preset alarm volume is greater than the preset intensity of the environment sound intensity;
s220, automatically outputting a preset driving current to an alarm loudspeaker through a power management device according to a preset alarm volume, wherein the volume of the alarm loudspeaker is in direct proportion to the preset driving current;
s230, judging whether the engineering vehicle starts to generate a preset action;
and S240, if the engineering vehicle starts to perform the preset action, making an alarm loudspeaker to sound.
According to the scheme for automatically adjusting the alarm volume, the power management device can automatically convert the preset adjustment volume into the preset current signal. The volume of the alarm loudspeaker 3 is in direct proportion to the current output by the power management device. That is, the power management apparatus can automatically transmit a predetermined current signal to the alarm speaker 3 to adjust the volume of the alarm speaker 3 to a predetermined alarm volume, so that automatic adjustment of the volume of the alarm speaker 3 according to the intensity of the environmental sound can be achieved.
In an alternative of this embodiment, as shown in the flowchart provided in fig. 3, the intelligent warning method includes the following steps:
s300, acquiring the intensity of the environmental sound;
s310, acquiring preset alarm volume according to the environment sound intensity, wherein the sound intensity corresponding to the preset alarm volume is greater than the preset intensity of the environment sound intensity;
s320, displaying preset alarm volume to the outside;
s330, manually adjusting a volume adjusting piece of the alarm loudspeaker according to the preset alarm volume until the volume of the alarm loudspeaker reaches the preset alarm volume;
s340, judging whether the engineering vehicle starts to generate a preset action;
and S350, if the engineering vehicle starts to perform the preset action, making an alarm loudspeaker sound.
Wherein, the volume adjusting piece is a volume adjusting knob or a volume adjusting button which is commonly used in the prior art.
According to the scheme for manually adjusting the alarm volume, a driver can operate the volume adjusting piece according to the displayed preset alarm volume so as to manually adjust the volume of the alarm loudspeaker 3 to the preset alarm volume, so that the alarm sound intensity is adaptive to the environment sound intensity.
It is worth emphasizing that the scheme of manually adjusting the volume of the alarm speaker 3 and the scheme of automatically adjusting the volume of the alarm can be simultaneously applied to the engineering vehicle, and for one-time alarm operation, a driver can select and use the scheme of automatically adjusting the alarm volume or the scheme of manually adjusting the alarm volume according to requirements.
In an alternative of this embodiment, as shown in the flowchart provided in fig. 4, the intelligent warning method includes the following steps:
s400, judging whether the pilot switch is in an open state;
s410, if the pilot switch is in an open state, acquiring the intensity of the environmental sound;
s420, acquiring a preset alarm volume according to the environment sound intensity, wherein the sound intensity corresponding to the preset alarm volume is greater than the preset intensity of the environment sound intensity;
s430, adjusting the volume of the alarm loudspeaker to a preset alarm volume;
s440, judging whether the engineering vehicle starts to generate a preset action;
s450, if the engineering vehicle starts to perform the preset action, the alarm loudspeaker is made to sound.
The pilot switch 4 is used for controlling the opening and closing of a main valve of the whole hydraulic circuit of the engineering vehicle. That is, the construction vehicle can perform the construction action only when the pilot switch 4 is turned on.
The steps of obtaining the environmental sound intensity, obtaining the preset alarm volume, adjusting the volume of the alarm loudspeaker 3 and judging whether the engineering vehicle starts to perform the preset action are carried out based on the construction state of the engineering vehicle, otherwise, the waste of the control flow is caused; and the engineering vehicle can only implement the intelligent control method through the intelligent control system, and the waste of the control flow can cause the waste of the execution action of the intelligent control system and the consumption of energy. Therefore, the environmental sound intensity is acquired only when the pilot switch 4 is turned on, and the volume of the alarm speaker 3 is adjusted, so that the intelligent alarm method can not be executed when the alarm is not required.
In an alternative of this embodiment, as shown in the flowchart provided in fig. 5, the intelligent warning method includes the following steps:
s500, judging whether a pilot switch is in an open state;
s510, if the pilot switch is in an open state, acquiring the intensity of the environmental sound;
s520, acquiring preset alarm volume according to the environment sound intensity, wherein the sound intensity corresponding to the preset alarm volume is greater than the preset intensity of the environment sound intensity;
s530, adjusting the volume of the alarm loudspeaker to a preset alarm volume;
s540, judging whether the engineering vehicle starts to perform the turning motion, and if the engineering vehicle starts to perform the turning motion, jumping to S560;
s550, if the engineering vehicle does not have the rotation action, judging whether the engineering vehicle starts to have the walking action, and if the engineering vehicle starts to have the walking action, skipping to the step S560;
and S560, making the alarm loudspeaker sound.
The preset action comprises a turning action and a walking action, so that the volume of the alarm loudspeaker 3 can be adjusted to the preset alarm volume along with the change of the environmental sound intensity in the state that the pilot switch is turned on. Therefore, when the engineering vehicle starts to perform rotation or walking actions such as forward movement and backward movement, the alarm loudspeaker 3 gives an alarm with preset alarm volume to remind surrounding workers and other vehicles of paying attention to the rotation and walking actions of the engineering vehicle, so that construction danger caused by rotation and walking of the vehicle is avoided.
In other words, the alarm sound can be emitted in three cases: when the engineering vehicle starts to independently perform the rotation action; under the condition that the engineering vehicle starts to independently generate walking action; when the working vehicle starts to perform the turning operation and the traveling operation at the same time.
It can be understood that, after the work vehicle starts to perform the walking action, it may be determined whether the work vehicle performs the turning action.
In an alternative of this embodiment, as shown in the flowchart provided in fig. 6, the intelligent warning method includes the following steps:
s600, judging whether a pilot switch is in an open state;
s610, if the pilot switch is in an open state, acquiring the intensity of the environmental sound;
s620, acquiring a preset alarm volume according to the environment sound intensity, wherein the sound intensity corresponding to the preset alarm volume is greater than the preset intensity of the environment sound intensity;
s630, adjusting the volume of the alarm loudspeaker to a preset alarm volume;
s640, judging whether a rotary pressure switch of the engineering vehicle is in an open state, and if the rotary pressure switch is in the open state, jumping to the step S660;
s650, if the rotary pressure switch is in a closed state, judging whether the traveling pressure switch of the engineering vehicle is in an open state, and if the traveling pressure switch of the engineering vehicle is in the open state, jumping to the step S660;
and S660, making the alarm loudspeaker sound.
The walking pressure switch 7 is used for monitoring the pressure and the on-off state of a walking hydraulic circuit of the engineering vehicle in real time, in other words, if the walking pressure switch 7 is in an on state, it indicates that the engineering vehicle starts to perform the walking action.
The rotary pressure switch 6 is used for detecting the pressure and the on-off of a rotary hydraulic circuit of the engineering vehicle in real time, in other words, if the rotary pressure switch 6 is in an open state, the rotary pressure switch indicates that the engineering vehicle starts to perform the rotary action.
Because the rotary pressure switch 6 and the walking pressure switch 7 are both the existing structure of the engineering vehicle, whether the engineering vehicle starts to perform rotary action and walking action is determined by judging whether the rotary pressure switch 6 and the walking pressure switch 7 are in an open state, the determination mode is simple and easy, other detection mechanisms are not required to be added to determine whether the engineering vehicle performs rotary action and walking action, and the structure of an intelligent warning system for implementing the intelligent warning method is simplified.
