DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] Referring to FIGS. 4, 5, and 6, which are respectively a schematic side view showing a processing machine and a security recognition system according to the present invention, a schematic view demonstrating use of the processing machine and the security recognition system according to the present invention, and a schematic view demonstrating another use of the security recognition system according to the present invention, the present invention provides a human-body-defined security recognition system of the processing machine The processing machine 1 at least comprises an electric driving device 11. The electric driving device 11 at least drives a transmission portion 12. The transmission portion 12 is at least connected to a processing portion 13. The processing portion 13 comprises a cutting tool 131 that is driven by the transmission portion 12. The processing machine 1 is at least connectable with a security recognition system 3 that establishes definition of a human body 2, The security recognition system 3 at least comprises a central processing unit 31. The central processing unit 31 is at least connectable to an input device 32 and at least one display element 34. The central processing unit 31 is connected with a camera device 35 that is arranged to correspond to the cutting tool 131. The central processing unit 31 at least comprises a terminal 311 that is connectable with the electric driving device 11. The central processing unit 31 is operable to plan or determine a security recognition zone A that a human body 2 is not allowed to enter or is supposed not to enter based on a positional image of the cutting tool 131 captured or photographed by the camera device 35 according to vicinity of the cutting tool 131 defined by means of the input device 32, such that the central processing unit 31, upon identifying entry of the human body 2 into the security recognition zone A, immediately shuts down and stops the electric driving device 11 and the cutting tool 131 and makes related displaying on the display element 34. Further, the processing machine is not limited to a processing machine 1 for carpentry, and the processing machine 1 can be used in combination with processing machines of various fields that require installation of the security recognition system 3 for collaborative operation therewith (see FIGS. 4 and 5).

[0018] The central processing unit 31 according to the present invention is at least connectable with a brake portion 36 disposed on the transmission portion 12. The brake portion 36 at least comprises a power element 361. The power element 361 comprises a braking element 362 that is selectively drivable to stop and jam the transmission portion 12. Further, the display element 34 can be a touch screen(as shown in FIGS. 4 and 5). In addition to and outside the security recognition system A, a human body security recognition wearable piece B is provided for being worn by the human body 2 to be detected and identified by the central processing unit 31 within the security recognition zone A. The human body security recognition wearable piece B is provided, for example on a surface thereof, with a recognizable object B1 that is detectable and identifiable by the central processing unit 31 such that the central processing unit 31 may recognize, through detection of the recognizable object B1 on the human body security recognition wearable piece B, whether the human body is in the security recognition zone A (as shown in FIG. 5).

[0019] Thus, the security recognition system 3 according to the present invention uses the central processing unit 31 to recognize the human body 2 entering the security recognition zone A, such that upon entry of the human body 2 into the security recognition zone A, the central processing unit 31 signals through the terminal 311 to activate or shut down the electric driving device 11 and the cutting tool 131 and also to drive the power element 361 to stop and jam the transmission portion 12 by means of the braking element 362. Further, the recognizable object B1 enhances or strengthens the effect of detection and identification of a part of the human body 2 by the central processing unit 31. As such, the human body 2, who enters the security recognition zone A, is protected from contacting the cutting tool 131 in all circumstances (as shown in FIGS. 5 and 6).

[0020] One can appreciate from the above description that the central processing unit 31 of the security recognition system 3 according to the present invention is connectable, through the terminal 311, to the electric driving device 11; the cutting tool 131 driven by the electric driving device 11 is provided with the camera device 35; and the central processing unit 31 plans and determines the security recognition zone A that a human body 2 is not allowed to enter based on a positional image of the cutting tool 131 captured or photographed by the camera device 35 according to vicinity of the cutting tool 131 defined by means of the input device 32, wherein the security recognition zone A is displayed on the display element 34 to allow for effective monitoring the human body 2 approaching the cutting tool 131 by means of the security recognition zone A to achieve an effect that the central processing unit 31 signals to shut down the electric driving device 11 upon the entry of the human body 2 into the security recognition zone A. This is the primary advantageous feature of the present invention.

[0021] The central processing unit 31 of the security recognition system 3 according to the present invention uses the camera device 35 and the security recognition zone A to achieve effective monitoring a condition of operation of the cutting tool 131 so as to achieve an effect that the central processing unit 31 signals to drive the power element 361 to stop and jam the operation of the transmission portion 12 by means of the braking element 362 upon the entry of the human body 2 into the security recognition zone A. This is another advantageous feature of the present invention.

[0022] The central processing unit 31 of the security recognition system 3 according to the present invention uses an image captured by the camera device 35 to identify the recognizable object B1 worn on the human body 2 entering the security recognition zone A, so as to achieve an effect that the central processing unit 31 signals to drive the power element 361 to stop and jam the operation of the transmission portion 12 by means of the braking element 362 upon the entry of the recognizable object B1 into the security recognition zone A. This is a further advantageous feature of the present invention.
