Of course, the number of the cameras 1 to be selected is not particularly limited in the present application, and is determined according to the actual situation.
As a preferred embodiment, further comprising:
and a switch 4 connected to the plurality of cameras 1, the image processor 2, and the control device 5, respectively, for communication between the cameras 1 and the image processor 2 and between the image processor 2 and the control device 5.
When the number of the cameras 1 is multiple, considering that the number of the communication interfaces in some image processors 2 is not so large, and the image processors cannot be directly connected with the cameras 1 and the control device 5 at the same time, in this embodiment, a switch 4 is further provided, the image processors 2 communicate with the cameras 1 through the switch 4, and the image processors 2 also communicate with the control device 5 through the switch 4, and this arrangement is suitable for the image processors 2 without too many communication interfaces, and reduces the occupation of the communication interfaces to the space of the image processors 2.
As a preferred embodiment, the camera 1 is a two-dimensional camera or a three-dimensional camera.
Specifically, the camera 1 may be a two-dimensional camera or a three-dimensional camera. The two-dimensional camera has the advantage of low cost, and the three-dimensional camera has the advantage of more accurate shape of the obtained sizing material. The specific camera to be selected is not particularly limited, and is determined according to the actual situation.
As a preferred embodiment, the alarm means 3 comprise acoustic alarm means and/or luminous alarm means.
Specifically, the sound alarm device emits sound alarm, and the light alarm device emits light alarm, where the sound alarm device may be but is not limited to a buzzer, and the light alarm device may be but is not limited to a flashlight.
As a preferred embodiment, further comprising:
a storage device connected to the image processor 2;
the image processor 2 is also arranged to save the pictures to the storage means.
Specifically, considering that the detection mode in the prior art cannot invade the occurrence process of an event, the responsibility determination in the event of an accident in the later period is inconvenient. In this embodiment, the image processor 2 stores the picture in the storage device after receiving the picture, so that a subsequent user can check and find the reason of the alarm by calling the picture, and even can determine the responsibility when a personal accident occurs in the later period.
As a preferred embodiment, further comprising:
a display device;
the image processor 2 is also arranged to display the picture on the display screen device after determining that an intrusion event has occurred.
In order to facilitate the checking of the working personnel, in the embodiment, the image processor 2 can display the picture on the display screen device after judging that the intrusion event occurs, so that the working personnel can directly find the current specific situation, the subsequent hidden danger can be conveniently eliminated, and the time for stopping the equipment is shortened.
As a preferred embodiment, the display device is an upper computer.
Specifically, the tire building machine is usually equipped with an upper computer directly interacting with a user, and in the embodiment, the upper computer can also display specific abnormal types, so that an additional display device is not needed, and the cost is reduced.
