Special safety monitoring intelligent switch for industrial special door

Abstract

The invention relates to a special safety monitoring intelligent switch for an industrial special door which belongs to the technical field of the processing of the industrial special door. The intelligent switch comprises a base plate, and a contact module is arranged on the upper end of the base plate. The switch is characterized in that a sliding contact disk composed of an upper copper ring and a lower copper ring is arranged on the base plate of the non-roller side of an arm sensor, the upper and lower copper rings are formed by copper plates; a wire is arranged in the arm sensor, the long end of the sliding contact disk side of the arm sensor contacts with the lower copper ring; a magnetic switch and a jumper switch are arranged under the contact module, the copper plates of the upper copper ring are separately connected with the contacts on one side of the jumper switch, the contacts on the other side of the jumper switch are connected with one end of the magnetic switch, the other end of the magnetic switch is connected with a 0V power source; and the copper plates of the lower copper ring are connected with the input end of the contact module, and the output end of the contact module and the end, connected with the 0V power source, of magnetic switch are separately connected with a safety monitoring circuit.

Description

Technical field: [0001] The invention belongs to the technical field of industrial special door processing, and in particular relates to a special safety monitoring intelligent switch used in an industrial special door control system. Background technique: [0002] At present, in the existing industrial special door control systems, most of the signal feedback comes directly from travel switches or sensors, and industrial special doors are often used in extremely harsh industrial environments, and cannot completely avoid dust, low or high temperature, and mechanical scratches. , vibration and surrounding strong magnetic field and other factors, and any kind of unfavorable factors may cause the deviation of the switch position, the damage of the switch function, the failure or error of the signal feedback, and this will cause the driving mechanism of the industrial special door (Drive motor) misoperation brings great potential safety hazards, ranging from damage to the door b...
