The notification process is a process for alerting the operator of the crane 1 to operate the crane 1. Although the timing for executing this notification process is arbitrary, in the embodiment, it is started after the notification system 50 is powered on.

When the notification process is started, as shown in FIG. 4, the control unit 85 acquires first detection data from the first detection unit 61 via the control side communication unit 82 in SA1.

In SA2, the control unit 85 acquires second detection data from the second detection unit 71 via the control side communication unit 82.

At SA5, the control unit 85 acquires turning angle detection data from the turning angle detection unit 73 via the control side communication unit 82.

In SA6, the notification unit 85a alerts the operator of the crane 1 to operate the crane 1 based on at least the first detection data acquired in SA1 and the second detection data acquired in SA2. Determine whether or not.

Although the determination method for determining whether or not to issue this warning is arbitrary, the determination may be made as follows, for example.

That is, first, regarding the first determination method, it is determined whether or not to issue the above-mentioned warning based on the first detection data acquired in SA1 and the second detection data acquired in SA2. good. As an example, it is possible to determine whether at least one of the wind speed of the first detection data or the wind speed of the second detection data is equal to or higher than a threshold, or whether the wind speed of the first detection data and the wind speed of the second detection data acquired during a predetermined time are Judgment is made based on whether the number of times a difference with the wind speed has occurred (for example, the number of times a difference of more than a predetermined value has occurred) is greater than or equal to a predetermined number, and if it is greater than or equal to the threshold value or greater than the predetermined number of times. In this case, it may be determined that the above-mentioned warning is to be performed, and if the number of times is not equal to or greater than the threshold value or the number of times is not equal to or greater than the predetermined number of times, it may be determined that the above-mentioned warning is not performed. With such a first determination method, it is possible to accurately determine whether or not the above-mentioned warning should be given, and it is possible to notify the warning information at an appropriate timing.

In addition, regarding the second determination method, the above-mentioned warning is issued based on the first detection data acquired in SA1, the second detection data acquired in SA2, and the imaging data acquired in SA3. It may be determined whether or not to perform. As an example, first, the swing amplitude of the hook 16 or the suspended load W in the above-mentioned image data is specified using a known image analysis method (for example, based on the position or size of an object on the ground, the swing width of the hook 16 or Specify the swing amplitude of the suspended load W). Next, in addition to the first determination method, it is determined whether the swing amplitude is equal to or greater than a threshold value, and if it is equal to or greater than the threshold value, regardless of the determination result by the first determination method described above, It may be determined that a warning is to be given. With such a second determination method, it becomes easier to make a determination according to the situation than when only the first determination method is used, and therefore it becomes easier to notify alerting information at an appropriate timing.

Regarding the third determination method, the first detection data acquired in SA1, the second detection data acquired in SA2, the imaging data acquired in SA3, and the second detection data acquired in SA4 are Based on the measurement data, it may be determined whether or not to issue the above-mentioned warning. As an example, first, the swing amplitude of the hook 16 or the hanging load W in the above-mentioned image data is specified using a known image analysis method, and a predetermined swing angle of the hook 16 (for example, it is possible to safely swing the hanging load W) is determined. An allowable swing width corresponding to the hook height during SA4 processing is calculated based on the maximum possible swing angle, etc.). Next, in addition to the first determination method, it is determined whether the vibration amplitude is greater than or equal to the allowable vibration amplitude, and if it is greater than or equal to the allowable vibration amplitude, the determination result by the first determination method is determined. Regardless of the above, it may be determined that the above-mentioned warning is to be issued. By using such a third determination method, it becomes easier to make a determination according to the situation than when performing the second determination method, and therefore it becomes easier to notify alerting information at an appropriate timing.

Here, the calculation method of the allowable swing width is arbitrary, but for example, as shown in FIG. 5, when the swing angle α of the hook 16 is the same, the hook 16 is Since the swing amplitudes γ ₁ and γ ₂ are different from each other, they may be calculated using the following formula (1).
γ _n =H _n /H ₀ ×γ ₀ ...Formula (1)
(Here, γ _n : Allowable swing width corresponding to the hook height during SA4 processing
H _n : Hook height during SA4 processing
H ₀ : Reference height of hook 16
γ ₀ : Allowable swing width corresponding to the reference height of the hook 16)

With such a calculation method, it is possible to easily calculate the allowable swing width according to the hook height.

Then, the notification unit 85a shifts to SA7 when it is determined that the above-mentioned caution is to be issued (SA6, Yes), and shifts to SA8 when it is determined that the above-mentioned caution is not to be issued (SA6, No). do.

In SA7, the notification unit 85a notifies alerting information, and then proceeds to SA8.

Although the method of reporting this alert information is arbitrary, it may be reported as follows, for example.

That is, when the alerting information includes only information indicating that the above-mentioned alerting is to be carried out (hereinafter referred to as "basic alerting information"), the alerting information (basic alerting information) is outputted via the output unit 83. It may be displayed or outputted as a sound, or it may be displayed or outputted as a sound via the output unit 83 of the external device 51 by transmitting the alerting information to the external device 51 via the control side communication unit 82. .

In addition, if the alerting information includes other information in addition to the basic alerting information, the alerting information (basic alerting information and other information) may be displayed or audio outputted via the output unit 83. Alternatively, the alerting information may be displayed or audio outputted via the output unit 83 of the external device 51 by transmitting the alert information to the external device 51 via the control side communication unit 82 .

Here, in the case where the above other information is the first detection data acquired in SA1 and the second detection data acquired in SA2, the method of displaying the alert information is arbitrary, but for example, As shown in FIG. 6, among the areas on the screen of the output unit 83, there is an area 83a (hereinafter referred to as "attention area 83a") for alerting the operator of the crane 1 to the operation of the crane 1. ), the basic caution information D1 (for example, text data including a standard message such as "Please be careful when operating the crane") and the first detection data D2 (for example, "Wind speed = 35 m/sec, wind direction. = southeast") and the second detection data D3 (for example, text data indicating "wind speed = 33 m/sec, wind direction = southeast") may be displayed at the same timing (or at different timings). . With such a display, the first detection data and the second detection data can be presented to the operator of the crane 1, and the operator of the crane 1 can accurately grasp the wind situation around the crane 1. .

Furthermore, when the other information mentioned above is image data acquired in SA3 (or during SA7 processing), the method of displaying the alert information is arbitrary, but for example, as shown in FIG. The basic caution information D1 and the imaging data D4 may be displayed in an overlapping manner in the caution area 83a. With such a display, the captured data can be presented to the operator of the crane 1, and the operator of the crane 1 can accurately grasp the situation of the suspended load W.

Further, in the case where the above other information is the first detection data acquired in SA1 and the turning angle detection data acquired in SA5, the method of displaying the alert information is arbitrary, but for example, As shown in FIG. 8, basic caution information D1, first detection data D2 (in FIG. 8, graphic data illustrated in a shape and size according to wind speed and wind direction), and turning angle are provided in the caution area 83a. The detection data D5 (in FIG. 8, graphical data illustrating a state in which the crane 1 has turned at the turning angle of the turning angle detection data D5) may be displayed at the same timing (or at different timings). With such a display, the first detection data and the turning angle data can be presented to the operator of the crane 1, making it easier for the operator of the crane 1 to understand the influence of the wind on the suspended load W.

Further, in the case where the above other information is data indicating the prediction result of the prediction unit 85b (hereinafter referred to as "prediction data"), the method of displaying the alert information is arbitrary, but for example, as shown in FIG. As shown in FIG. 9, the basic caution information D1, the turning angle detection data D5 acquired during the processing of SA7, and the predicted data D6 (in FIG. 9, the shape and size according to the wind speed and direction are The graphic data illustrated in Figure 1 and the text data indicating "wind speed and wind direction at the construction stage of the 8th floor" may be displayed at the same timing (or at different timings). However, the present invention is not limited to this, and for example, the display of the turning angle detection data D5 may be omitted. Alternatively, the first detection data acquired in SA1, the second detection data acquired in SA2, the imaging data acquired in SA3 (or during SA7 processing), or the past wind speed and direction stored in the wind direction DB 86a. Among the past wind speed and direction information, past wind speed and direction information corresponding to construction information acquired via the operation unit 81 or the control side communication unit 82 may be displayed. With such a display, the predicted data can be presented to the operator of the crane 1, and the operator of the crane 1 can grasp the wind situation around the hook 16 in advance at a predetermined construction stage. In particular, when strong winds are expected at night, the crane body 10 can be rotated so that the angle and direction of the boom 13 are at a safe angle and direction, and this can be used as data to ensure the safety of the operation of the crane 1. .

Although the method for creating the above prediction data is arbitrary, for example, first, the prediction unit 85b selects the operation unit 81 or the control side communication unit 82 from the past wind speed and direction information stored in the past wind speed and direction DB 86a. Past wind speed and direction information corresponding to the construction information acquired through is extracted, and a learned model is created using machine learning (for example, deep learning) using the extracted past wind speed and direction information. Next, the prediction unit 85b uses the learned model to obtain desired construction information (for example, construction information indicating the current or subsequent construction stage) acquired via the operation unit 81 or the control side communication unit 82. It may be created by predicting the wind speed and wind direction around the hook 16. However, the present invention is not limited to this. For example, the prediction unit 85b averages the wind speed and wind direction of the past wind speed and direction information extracted above, and sets the averaged wind speed and wind direction as the predicted wind speed and wind direction. You may.

Returning to FIG. 4, in SA8, the control unit 85 determines whether the timing to end the notification process (hereinafter referred to as "end timing") has arrived.

The method for determining whether or not this end timing has arrived is arbitrary, but for example, it may be determined based on whether or not a predetermined operation is accepted via the operation unit 81, and when the predetermined operation is performed, It is determined that the end timing has arrived, and if the above-mentioned predetermined operation is not performed, it is determined that the end timing has not arrived.

Then, when it is determined that the end timing has arrived (SA8, Yes), the control unit 85 ends the notification process. On the other hand, if it is determined that the end timing has not arrived (SA8, No), the process moves to SA1, and the processes from SA1 to SA8 are repeated until it is determined in SA8 that the end timing has arrived.

The above-described notification processing allows the operator of crane 1 to be more careful when operating crane 1, compared to conventional technology (technology that displays information indicating the detection results of wind direction and wind speed detectors installed on tower posts on a display panel). It is possible to accurately recognize whether or not to pay the crane 1, thereby increasing the safety of operating the crane 1. Further, it is possible to notify alert information based on the first detection data, second detection data, and imaging data, and it becomes easier to notify alert information according to the situation.
