Photoelectric sensor combined type production line vehicle type identification system

Abstract

The invention discloses a photoelectric sensor combined type production line vehicle type recognition system which comprises a detection frame, the detection frame is provided with a vehicle inlet and a vehicle outlet, the bottom of the detection frame is fixedly connected with a conveying table, and the conveying table is fixedly connected with the bottom of the detection frame; a plurality of detection frames for vehicles to be detected are movably arranged in the length direction of the conveying table; a photoelectric switch used for detecting the outline of the side face of a vehicle body, a laser distance measuring sensor used for detecting the distance between the outline of the vehicle body and a specific point and a programmable controller used for determining the vehicle type are fixedly connected into the detection frame. Through the photoelectric switch, the laser distance measuring sensor and the programmable controller, all vehicle types on the production line can be accurately identified, the cost is low, the maintenance is convenient, and the device is suitable for efficiently and accurately identifying various vehicle types on the automobile production line using the programmable controller.

Description

technical field [0001] The invention relates to an identification system, in particular to a vehicle identification system for a photoelectric sensor combined production line. Background technique [0002] In the automatic production line of automobiles, there are extremely high requirements for the accuracy of vehicle model recognition. When there is a wrong identification of the vehicle type, the collision between the vehicle body and the moving mechanism may occur, resulting in large economic losses. Moreover, the identification system should be easy to maintain and avoid waste of resources caused by production line shutdown. [0003] At present, in the multi-vehicle mixed production line, the commonly used identification methods: one is the combination of photoelectric switches and programmable controllers; the other is the form of multi-cameras with special identification software to output vehicle model data. [0004] The first method is easy to maintain and has a si...

Problems solved by technology

[0004] The first method is easy to maintain and has a simple structure. It is used to identify vehicle models in many production lines, but it is difficult to use in flexible production lines with multiple models. If there are more models, the required photoelectric switches will increase, and it will affect the body. Detection in the width direction is also difficult

[0005] The second method has high accuracy and does not require additional hardware for the addition of new models, but requires independent operating software, software maintenance requires professionals, and equipment costs are also high, requiring multiple sets of cameras for combined measurement
