A warning assembly 106 is disposed on the beam 105 of the Y-rail assembly 102. In other embodiments, the alert component 106 may be disposed at other locations of the fuselage. When the radar detection module works, the monitoring in the preset area (see fig. 4 for a schematic diagram of the preset area) can be performed in the preset area of 180 degrees. Therefore, the radar detection module is utilized to enlarge the monitoring range and angle, which are far higher than the existing photoelectric monitoring range (linear). When the cutting machine operates like this, detect the information in the predetermined detection zone and feed back detection information to control module based on the radar detection module, control module receives and responds detection information control cutting machine and operates in the mode of matching, if, normal operating, the operation of slowing down, stop at once. The schematic diagram of the functional module of the cutting machine is shown in fig. 3, and the control module is electrically connected with the radar detection module, the warning assembly and the driving part of the Y-rail assembly. The operation control module controls the warning assembly and the Y-rail assembly based on the received information detected by the radar detection module. Of course, the control module also controls the clipping to run based on the instructions.
The control method of the cutting machine proposed by the present application is described next with reference to fig. 5:
when the cutting machine starts to operate, the information in the preset detection area is detected based on the radar detection module and the detection information is fed back to the control module, and the detection area (refer to fig. 4) comprises: the cutting machine is characterized by comprising a first preset range (namely a stop area) and a second preset range (namely a low-speed running area) located outside the first preset range, wherein when the cutting machine runs, whether obstacles exist in the second preset range is detected firstly, if yes, whether obstacles exist in the first preset range is further detected, so that the cutting machine works in a first working mode or stops running based on the judged information, and if not, the cutting machine works in a second working mode. The cutting machine is prevented from immediately stopping running once the obstacle is detected, and the utilization rate of the cutting machine is improved. The control method comprises the following steps:
if the radar detection module detects that an obstacle (such as a human body) exists in the second preset range, the detection information is fed back to the control module, the control module receives and responds to the detection information to control the cutting machine to operate in the first working mode, then the radar detection module detects whether the obstacle exists in the first preset range,
if the first preset range has obstacles (such as human bodies), the control module controls the cutting machine to stop running, if the first preset range has no obstacles, the control module controls the cutting machine to maintain the current first working mode until the next sampling period,
if the radar detection module does not detect that the obstacle exists in the second preset range, the detection information is fed back to the control module, the control module receives and responds to the detection information to control the cutting machine to operate in a second working mode, and the operation speed (moving speed) of the Y-rail assembly in the second working mode is higher than that in the first working mode. In one embodiment, the cutting machine stopping includes the Y-rail assembly moving. And the cutting machine runs, the radar detection module samples information in the preset area in real time and feeds the sampled information back to the control module. Due to the design, the cutting machine runs in the first working mode (namely a low-speed running area) in some occasions, the work of the cutting machine is ensured under the safe condition, and the utilization rate of the cutting machine is improved. Whether an operator (sometimes called a human body) enters a preset detection area or not is detected based on the radar detection module in the process of starting operation.
The mechanism of switching between the different modes of operation of the cutting machine will be described next with reference to fig. 6.
If the cutting machine is in the second working die, the control module judges based on the information fed back by the radar detection module: if the low-speed information is high level (+) and the stop signal is low level (-), controlling the cutting machine to switch the first working mode to operate; if the low-speed information is low level (-) and the stop signal is low level (-), maintaining the current second working mode to operate;
if the cutting machine is in the first working die, the control module judges based on the information fed back by the radar detection module: if the low-speed information is high level (+) and the stop signal is high level (+), controlling the cutting machine to stop running; and if the low-speed information is low level (-) and the stop signal is low level (-), controlling the cutting machine to be switched to the second working mode to operate. Therefore, the control module receives and responds to the detection information fed back by the radar detection module to control the cutting machine to operate in a matched working mode (namely, the cutting machine operates in different working states).
In one embodiment, when the cutting machine stops operating, the control module controls the electrically connected warning component to send out a first prompt message. Therefore, the misoperation that an operator leans against and clings to the Y-rail assembly to operate is avoided, and accidents caused by the close contact behavior of the human body are effectively reduced. The first prompt message comprises a color alarm or a voice alarm sent by the warning component.
In one embodiment, when the cutting machine operates in the first working mode, the control module controls the electrically connected warning device to instruct to send out the second prompt message. The warning component comprises a lamp strip which can be configured on the Y beam, and the first prompt message comprises the color of the lamp strip for warning. In other embodiments, the warning assembly further comprises one or a combination of a warning light, a warning device. The warning assembly is arranged on the machine body or the Y-rail assembly.
In one embodiment, when the cutting machine operates in the second working mode, the control module controls the electrically connected warning device to send out a third prompt message.
In one embodiment, the cutting machine comprises an input module electrically connected to the control module, and the input module is used for configuring a first preset range and a second preset range detected by the radar detection module.
The cutting machine of the above embodiment can operate in different working modes in the design of the cutting machine, so that the cutting machine stops operating only in the area capable of causing injury according to the preset detection area (different influences on operators in the unused area) when the cutting machine operates, the cutting machine operates at a reduced speed when the injury is possibly caused and sends out prompt information to remind the operators to pay attention to/leave, and the cutting machine normally operates in the area without causing the injury. Frequent start and stop when avoiding the cutter operation like this, and then improve the operating efficiency.
In the design of the warning component, it may include one of a light strip, a warning light, a siren, or a combination thereof. The state (working mode) of the cutting machine is fed back in a real-time visualization mode. Taking the lamp strip as an example, when the cutting machine runs in the second working mode, the Y rail component normally works, and the lamp strip displays green. When the cutter ran in first mode, Y rail set spare reducing speed (low-speed removal), and the lamp area showed yellow. When the cutting machine stops running, the Y-rail component stops running, and the lamp strip displays red for warning, so that the lamp strip changes different colors to realize visualization of safety monitoring.
In the design of the detection area, the first preset range and the second preset range can be set through the input module. Can be according to cutter place size and demand, establish on-the-spot coordinate then self-defining detection area's shape and size through radar detection area editing software, transmit the detection area who defines to the radar detection module in.
