Description

technical field [0001] The invention relates to the field of industrial automation production, in particular to a design method of an intelligent sensor and an intelligent device. Background technique [0002] Infrared beam is a sensing method to detect whether there is occlusion within a specified range. It has a wide range of applications, such as life safety protection, animal intrusion sensing, object anti-theft protection, mechanical motion sensing, and speed measurement. [0003] For example, in a modern factory, people and machines work together. On some potentially dangerous mechanical equipment, such as stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission and handling equipment, hazardous areas (toxic , high pressure, high temperature, etc.), it is easy to cause personal injury to the workers. In the prior art, by installing a photoelectric safety protection device, the photoelec...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following disadvantages: 1. The cost of the safety protection device in the prior art is high. The safety protection device is composed of a photoelectric transmitter and a photoelectric receiver and a signal cable and a control cable connected between them. When a light curtain needs to be formed, Multiple pairs of photoelectric transmitters and photoelectric receivers must be used to form a light curtain with gaps. Engineers design to form a light curtain and need to design the cooperation of multiple pairs of photoelectric transmitters and photoelectric receivers.

[0005] 2. The signal transmission cable is easily disturbed by the strong electromagnetic environment, which causes sequence errors when the device scans, and the cable length is limited and the protection distance is short

[0006] 3. In the prior art, there is a gap between two adjacent photoelectric emitting elements of the safety protection device. If the blocking object is small enough and located in the gap area between the two grating bars, the existence of the blocking object cannot be detected, and there is room for improvement.

[0007] 4. The safety protection device in the existing technology cannot self-check in real time. If it suddenly fails during the use of the equipment, the problem cannot be found in real time, which may lead to detection failure or personal safety accidents. There is room for improvement

[0008] 5. There are gaps that cannot be detected in the existing technology. The hand may bypass the infrared rays and enter the dangerous area, which affects safety and has room for improvement.
