In this regard, the prior art provides an anti-collision system that includes a distance sensor mounted on a work platform of an overhead working truck, the distance sensor being configured to detect a distance between the work platform and an obstacle, and after detecting that the distance between the work platform and the obstacle is smaller than a preset value, the prior art generally takes measures to directly limit a lifting device to drive the work platform to continue to lift or translate, and for safety reasons, the preset value is generally set to be larger, so that the lifting device cannot continue to drive the work platform to lift or translate when the work platform is still far from the obstacle, and if the preset value is set to be smaller, the work platform or the worker is likely to collide with the obstacle.
Aiming at the problems, the embodiment provides a safety monitoring method for the overhead working truck, which can adopt different control strategies according to the minimum distance between a working platform and an obstacle and can be used in the technical field of safety monitoring of the overhead working truck.
The safety monitoring method for the overhead working truck provided by the embodiment can be implemented through the overhead working truck, wherein the overhead working truck comprises a truck body, a lifting device arranged on the truck body and a working platform arranged on the lifting device, and the lifting device is used for driving the working platform to ascend, descend or translate.
Referring to fig. 1, the safety monitoring method of the overhead working truck includes an obstacle distance detection method including the following steps.
S100: the minimum distance between the working platform and the obstacle is obtained.
The minimum distance between the work platform and the obstacle can be used as a basis for judging whether the work platform is about to collide with the obstacle.
The obtaining of the minimum distance between the working platform and the obstacle comprises the following steps: the method comprises the steps of obtaining the distance between the front side wall of the operation platform and an obstacle, the distance between the left side wall of the operation platform and the obstacle, the distance between the right side wall of the operation platform and the obstacle and the distance between the upper side wall of the operation platform and the obstacle, and taking the minimum value as the minimum distance between the operation platform and the obstacle. Specifically, four ultrasonic sensors can be used for obtaining, and the four ultrasonic sensors are respectively arranged on the front side wall, the left side wall, the right side wall and the upper side wall of the operation platform. The distance between the front side wall of the operation platform and the obstacle can be obtained through an ultrasonic sensor arranged on the front side wall of the operation platform, the distance between the left side wall of the operation platform and the obstacle can be obtained through an ultrasonic sensor arranged on the left side wall of the operation platform, the distance between the right side wall of the operation platform and the obstacle can be obtained through an ultrasonic sensor arranged on the right side wall of the operation platform, and the distance between the upper side wall of the operation platform and the obstacle can be obtained through an ultrasonic sensor arranged on the upper side wall of the operation platform. It will be appreciated that the above-mentioned ultrasonic sensors are each configured to detect a distance between themselves and an obstacle, and that the ultrasonic sensor is provided on the work platform, and that the distance between itself and the obstacle detected by the ultrasonic sensor is considered to be the distance between the work platform and the obstacle.
S110: and comparing the minimum distance between the working platform and the obstacle with a first distance threshold.
If the minimum distance between the working platform and the obstacle is not greater than the first distance threshold, it indicates that the distance between the working platform and the obstacle is slightly smaller at this time, and the aerial work can still be continued at this time, but the movement speed of the working platform needs to be limited, so steps S120-S130 are executed.
If the minimum distance between the working platform and the obstacle is greater than the first distance threshold, it indicates that the distance between the working platform and the obstacle is longer, and the working at high altitude is not affected, so that the process returns to step S100.
S120: and the speed of the lifting device when driving the working platform to ascend or translate is reduced.
Through the steps, the working personnel can still carry out high-altitude operation, but the movement speed of the operation platform is reduced, so that the safety is ensured.
Optionally, the aerial vehicle safety monitoring method further includes step S700 performed in synchronization with step S120.
S700: a medium risk alert message is issued.
Medium risk alert information includes audible, visual signals, etc., with a lower audible, lower light.
S130: and comparing the minimum distance between the working platform and the obstacle with a second distance threshold value, wherein the second distance threshold value is smaller than the first distance threshold value.
If the minimum distance between the work platform and the obstacle is not greater than the second distance threshold, it indicates that the distance between the work platform and the obstacle is already very close, and the lifting and translation of the work platform need to be completely limited, so step S140 is performed.
S140: limiting the lifting device to drive the working platform to ascend and translate.
The lifting device is limited to drive the working platform to ascend and translate through the steps, and only the working platform is allowed to descend.
Optionally, the aerial vehicle safety monitoring method further includes step S710 performed in synchronization with step S140.
S710: high risk alert information is issued.
The high risk warning information includes sound, light signals and the like, and has higher sound and higher brightness so as to remind workers and car body drivers of taking relevant operations as soon as possible, such as lowering a working platform and the like.
Optionally, in step S130, if the minimum distance between the work platform and the obstacle is greater than the second distance threshold, the lifting device is not required to be limited to drive the work platform to lift and translate, but the speed of the lifting device when driving the work platform to lift or translate is already reduced, the minimum distance between the work platform and the obstacle may be repeatedly obtained, and the limitation on the movement speed of the work platform is released when the minimum distance between the work platform and the obstacle is greater than the first distance threshold, and in addition, if it is subsequently detected that the minimum distance between the work platform and the obstacle is not greater than the second distance threshold, step S140 is performed.
By the safety monitoring method for the overhead working truck, lifting and translation actions of the working platform can be normally performed when the minimum distance between the working platform and the obstacle is far, namely, the minimum distance between the working platform and the obstacle is larger than the first distance threshold. When the minimum distance between the working platform and the obstacle is slightly short, namely the minimum distance between the working platform and the obstacle is not greater than the first distance threshold value and is greater than the second distance threshold value, the speed of the lifting device when driving the working platform to ascend or translate is reduced, so that a worker positioned on the working platform can still continue working, and more reaction time can be given to the worker if an emergency condition is met. When the minimum distance between the working platform and the obstacle is very close, namely the minimum distance between the working platform and the obstacle is not greater than a second distance threshold value, the lifting and translation of the working platform are limited, so that the working personnel and the working platform are protected. The safety monitoring method for the overhead working truck can adopt different control strategies according to the minimum distance between the working platform and the obstacle.
In the working engineering of the overhead working truck, because the working platform is generally located at the high altitude, wind speed near the working platform can cause larger wind load moment of the working platform, and the wind load moment can also influence the overhead working. Referring to fig. 2, in order to address the above-mentioned problems, the method for monitoring safety of an aerial working vehicle according to the present embodiment further includes an ambient wind speed detection method, where the ambient wind speed detection method includes the following steps.
S200: and acquiring the wind speed of the environment where the working platform is located.
Specifically, the wind speed of the environment where the working platform is located can be obtained by a wind speed sensor arranged on the working platform.
The step S200 may be executed synchronously with the step S100, or the step S100 may be executed first and then the step S200 may be executed, or the step S200 may be executed first and then the step S100 may be executed, according to the actual situation. In this embodiment, step S200 is performed in synchronization with step S100.
S210: and comparing the wind speed of the environment where the working platform is positioned with the first wind speed threshold value.
If the wind speed of the environment where the working platform is located is not less than the first wind speed threshold value, it indicates that the wind speed of the environment is slightly greater at this time, and the wind load moment will have a certain influence on the working platform, but the wind load moment can still be overcome by reducing the speed when the lifting device drives the working platform to rise or translate, and the wind load moment can be used for rush repair operation under severe weather conditions, etc., so that step S220 is executed at this time. If the wind speed of the environment where the working platform is located is smaller than the first wind speed threshold value, the condition is indicated that the environment wind speed is smaller at the moment, and the working at high altitude cannot be influenced, so that the step S200 is returned.
S220: and the speed of the lifting device when driving the working platform to ascend or translate is reduced.
Alternatively, step S700, i.e., issuing medium risk alert information, is performed simultaneously while step S220 is performed.
After step S220, step S230 is continued.
S230: and comparing the wind speed of the environment where the working platform is positioned with a second wind speed threshold value, wherein the second wind speed threshold value is larger than the first wind speed threshold value.
If the wind speed of the environment where the working platform is located is not less than the second wind speed threshold, it indicates that the wind speed of the environment is extremely high at this time, and the lifting and translation of the working platform need to be completely limited, so step S240 is performed.
S240: limiting the lifting device to drive the working platform to ascend and translate.
The lifting device is limited to drive the working platform to ascend and translate through the steps, and only the working platform is allowed to descend.
Alternatively, step S710, i.e., issuing high risk alert information, is performed simultaneously while step S240 is performed.
Optionally, in step S230, if the wind speed of the environment where the working platform is located is less than the second wind speed threshold, the lifting device is not required to be limited to drive the working platform to rise and translate, but the speed of the lifting device when driving the working platform to rise or translate is already reduced at this time, the wind speed of the environment where the working platform is located can be repeatedly obtained, and when the wind speed of the environment where the working platform is located is less than the first wind speed threshold, the limitation on the movement speed of the working platform is released, and in addition, if it is subsequently detected that the wind speed of the environment where the working platform is located is not less than the second wind speed threshold, step S240 is executed.
In the working engineering of the overhead working truck, the fire disaster can also cause personal threat to drivers and staff. Referring to fig. 3, in order to address the above-mentioned problem, the method for monitoring safety of an aerial working vehicle according to the present embodiment further includes an environmental smoke concentration detection method, where the environmental smoke concentration detection method includes the following steps.
S300: and acquiring the smoke concentration of the environment where the vehicle body is located.
Specifically, the smoke concentration of the environment in which the vehicle body is located can be obtained by a smoke sensor provided to the vehicle body.
The step S300 may be executed synchronously with the step S100, or the step S100 may be executed first and then the step S300 may be executed, or the step S300 may be executed first and then the step S100 may be executed, according to the actual situation. In this embodiment, step S300 is performed in synchronization with step S100.
S310: and comparing the smoke concentration of the environment where the vehicle body is positioned with the concentration threshold value.
If the smoke concentration in the environment where the vehicle body is located is not less than the concentration threshold, it indicates that there is more smoke near the vehicle body at this time, possibly caused by fire, and this risk cannot be overcome by reducing the speed at which the lifting device drives the working platform to rise or translate, and at this time, the rising and translating of the working platform must be completely limited, so step S320 is performed. If the smoke concentration in the environment of the vehicle body is less than the concentration threshold, it indicates that the smoke near the vehicle body is less and there is no fire risk, and thus the process returns to step S300.
S320: limiting the lifting device to drive the working platform to ascend and translate.
The lifting device is limited to drive the working platform to ascend and translate through the steps, and only the working platform is allowed to descend.
Alternatively, step S710, i.e., issuing high risk alert information, is performed simultaneously while step S320 is performed.
In working engineering, the high-voltage line may exist near the working platform because the working platform is generally located at high altitude, and at this time, the worker has a risk of electric shock. Referring to fig. 4, in order to address the above-mentioned problem, the method for monitoring safety of an aerial working vehicle according to the present embodiment further includes an ambient magnetic field strength detection method, where the ambient magnetic field strength detection method includes the following steps.
S400: the magnetic field intensity of the environment where the working platform is located is obtained.
Specifically, the magnetic field strength of the environment where the working platform is located can be obtained through a hall sensor arranged on the working platform.
The step S400 may be executed synchronously with the step S100, or the step S100 may be executed first and then the step S400 may be executed, or the step S400 may be executed first and then the step S100 may be executed, according to the actual situation. In this embodiment, step S400 is performed in synchronization with step S100.
S410: comparing the magnetic field intensity of the environment where the working platform is positioned with the magnetic field intensity threshold value.
If the magnetic field strength of the environment where the working platform is located is not less than the magnetic field strength threshold, it indicates that the magnetic field strength near the working platform is high at this time, which is most likely caused by the presence of a high voltage line nearby, and this risk cannot be overcome by reducing the speed at which the lifting device drives the working platform to rise or translate, and at this time, the rising and translating of the working platform must be completely limited, so step S420 is performed. If the magnetic field strength of the environment where the working platform is located is smaller than the magnetic field strength threshold, it indicates that the magnetic field strength near the working platform is lower at this time, and no high-voltage line exists, so that the process returns to step S400.
S420: limiting the lifting device to drive the working platform to ascend and translate.
The lifting device is limited to drive the working platform to ascend and translate through the steps, and only the working platform is allowed to descend.
Alternatively, when step S420 is performed, step S710 is performed synchronously, i.e., high risk alert information is issued.
In the working engineering of the overhead working truck, the brightness of the environment where the truck body is located can also have a certain influence on the overhead working. Referring to fig. 5, in order to address the above-mentioned problem, the method for monitoring safety of an aerial working vehicle according to the present embodiment further includes an ambient brightness detection method, where the ambient brightness detection method includes the following steps.
S500: and acquiring the brightness of the environment where the vehicle body is located.
Specifically, the brightness of the environment in which the vehicle body is located can be obtained by a photosensor provided to the vehicle body.
The step S500 may be executed synchronously with the step S100, or the step S100 may be executed first and then the step S500 may be executed, or the step S500 may be executed first and then the step S100 may be executed, according to the actual situation. In this embodiment, step S500 is performed in synchronization with step S100.
S510: and comparing the brightness of the environment where the vehicle body is positioned with the brightness threshold value.
If the brightness of the environment of the vehicle body is not higher than the brightness threshold, it indicates that the brightness of the environment of the vehicle body is low at this time, and the driver and the staff are required to pay attention, but the operation is not required to be stopped immediately, so that steps S520-S530 are executed synchronously at this time. If the brightness of the environment of the vehicle body is higher than the brightness threshold, it indicates that the brightness of the environment of the vehicle body is higher at this time, and the driver and the staff do not need to pay special attention, so that the process returns to step S500.
S520: and the speed of the lifting device when driving the working platform to ascend or translate is reduced.
S530: the lighting device is turned on.
The lighting device is arranged on the vehicle body, and particularly is a lighting lamp arranged on the vehicle body.
