Example one

A first embodiment of the present invention provides a protection system, as shown in fig. 1, including: window 100, mechanical device 300, and sensing device 200; the sensing device 200 is mounted on the window 100;

a window 100 for allowing a person to put or take a sample in or out of the window 100 through the window 100;

the sensing device 200 is used for sensing that when a person puts a first sample through the window 100, the mechanical device 300 is controlled to stop taking the first sample; or when the sensing personnel takes the first sample through the window 100, the mechanical device 300 is controlled to stop putting the second sample; wherein the sample comprises a first sample and a second sample.

In this embodiment, in a physical inspection production line, in a process that a person puts in a sample or takes away the sample through the window 100, the mechanical device 300 in the window 100 takes away the put-in sample or puts the sample to be taken away, and in order to ensure that the mechanical device 300 operates safely and stably, the occurrence of accidents of casualties caused by collision between the mechanical device 300 and the person is avoided, a protection system is designed. When the protection system senses that a person puts a first sample in the window 100 through the sensing device 200, the mechanical device 300 is controlled to stop taking the first sample; when it is also sensed by the sensing device 200 that the person takes the first sample through the window 100, the mechanical apparatus 300 is controlled to stop taking the second sample. Therefore, the protection system judges whether the personnel and the mechanical equipment 300 collide or not through the sensing device 200, so that the mechanical equipment 300 enters an interrupt program, a pause response is rapidly generated on the mechanical equipment 300, the personal safety is protected, and meanwhile, a corresponding alarm is generated.
