[0002] Emergency stop switches in the tobacco industry's silk production workshop are spread across every corner of the workshop, and the silk production line requires continuity. If an emergency stop switch on the production line is accidentally triggered by a person or object, the equipment on the silk production line will be shut down urgently, resulting in interruption of silk production and ultimately affecting the quality of tobacco products.
[0003] Therefore, in order to prevent the emergency stop switch from being accidentally triggered, it is necessary to provide an emergency stop switch that prevents accidental triggering. The emergency stop switch indicator light flashes by detecting whether there is an object close to the emergency stop switch. The flashing function of the emergency stop switch indicator light can realize the purpose of reminding personnel not to allow objects or personnel to accidentally trigger the emergency stop switch, thereby avoiding the emergency stop switch being accidentally triggered and causing unnecessary emergency shutdown of the equipment.

[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1-Figure 4 The utility model is shown as an emergency stop switch for preventing false triggering, including an emergency stop switch signal line 1; an emergency stop switch indicator light signal line 2; a distance sensor signal line 3; a mounting panel 4; an emergency stop switch body 5; an emergency stop switch indicator light 6; a distance sensor 7; and a control system 8.
[0021] The emergency stop switch body 5 is a mushroom-shaped structure with a circular cross-section. A cylindrical distance sensor 7 is provided with the center of the cross-section of the emergency stop switch body 5 as the center of the circle and is embedded in the emergency stop switch body 5. An annular emergency stop switch indicator light 6 is provided along the outer circle of the distance sensor 7 and is embedded between the emergency stop switch body 5 and the distance sensor 7.
[0022] The emergency stop switch body 5 is fixedly mounted on the mounting panel 4 .
[0023] The other end of the emergency stop switch body 5 is provided with three signal lines, which are an emergency stop switch signal line 1, an emergency stop switch indicator light signal line 2, and a distance sensor signal line 3.
[0024] The emergency stop switch signal line 1 , the emergency stop switch indicator light signal line 2 , and the distance sensor signal line 3 are all connected to the control system 8 in a linear connection manner.
[0025] The detection distance of the distance sensor 7 is adjustable. When a person or object approaches the emergency stop switch body 5 and the distance from the emergency stop switch body 5 is less than the set detection distance of the distance sensor 7, the distance sensor 7 is triggered and transmits a signal indicating the approach of the person or object to the control system 8.
[0026] After the control system 8 receives the signal that a person or object is approaching, the control system 8 outputs a continuous flashing signal to the emergency stop switch indicator light 6 .
[0027] After the emergency stop switch indicator light 6 receives the continuous flashing signal output by the control system 8, the emergency stop switch indicator light 6 flashes.
[0028] When the emergency stop switch is not triggered, the emergency stop switch indicator light 6 will flash when and only when a person or object approaches the emergency stop switch body 5 and the distance from the emergency stop switch body 5 is less than the set detection distance of the distance sensor 7.
[0029] When the emergency stop switch is triggered, the emergency stop switch indicator light 6 is always on regardless of whether a person or an object is close to the emergency stop switch.
[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
