Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0026] An automatic identification device for relay shell numbers, such as figure 1 As shown, it includes image acquisition unit, machine vision processing unit and communication unit.

[0027] Image acquisition unit, such as figure 2 As shown, it consists of relay fixed platform 1, mixed light source 2 and industrial camera 3. The relay 4 to be identified is placed on the relay fixing platform 1 . Both the mixed light source 2 and the industrial camera 3 are located directly above the relay fixing platform 1 . The centerline of the industrial camera 3 coincides with the centerline of the hybrid light source 2 , and the centerline of the two coincides with the placement position of the relay 4 to be identified on the relay fixing platform 1 . The image output end of ...

Abstract

The invention discloses a relay shell number automatic identification device. The automatic identification device comprises an image acquisition unit, a machine vision processing unit and a communication unit. The image acquisition unit is composed of a relay fixing platform, a mixed light source and an industrial camera. A relay to-be identified is placed on the relay fixing platform. The mixed light source and the industrial camera are both located over the relay fixing platform. The center line of the industrial camera coincides with the center line of the mixed light source, and the centerlines of the industrial camera and the mixed light source are right opposite to the placement position of a to-be-identified relay on the relay fixing platform. The image output end of the industrialcamera is connected with the input end of the machine vision processing unit, and the output end of the machine vision processing unit is connected with an external input system through the communication unit. According to the invention, the problems of high labor intensity, strong subjectivity, easy fatigue, low accuracy, manual input and the like in the existing manual identification method canbe solved, and the method has the characteristics of high identification accuracy and high input efficiency.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an automatic identification device and method for relay case numbers. Background technique [0002] The military relay casing is made of metal, and the casing number consists of Arabic numerals, which are generated by etching the surface of the casing with laser marking equipment. When using these numbers, the operator needs to visually and recognize the stamped numbers on the relay casing, and then operate the keyboard to input the memorized numbers into the test software or information collection software in the computer. Since the human eye judges the content of characters by reflecting light differently from the character area and the background area, it may cause errors in the interpretation of the shell number due to random changes in light, and quality problems such as duplicate numbers, missing numbers, or wrong numbers may occur. In addition, manual entry of numbers is a...
