Rapid wire calibration device for photoelectric sensor

Abstract

The invention discloses a rapid wire calibration device for a photoelectric sensor. The device comprises a back plate which is provided with a terminal row, a switch quantity counter and a picture display. The number of terminals in the terminal row is larger than or equal to the number of cables in an encoder, all the cables of the encoder can be connected to the terminal row at the same time, the output end of each terminal in the terminal row is in a signal connection with an input end of the switch quantity counter simultaneously, and an output end of the switch quantity counter is in a signal connection with an input end of a picture display. The rapid wire calibration device has the advantages that the high and the low positions of each cable in the photoelectric encoder can be quickly determined, the wire calibration operation of one photoelectric encoder can be completed in only 5 minutes, time and labor are saved, the accuracy is high, the completion rate of one time of wire calibration reaches 100%, so that the photoelectric encoder can be correctly and quickly connected to a mine slot loading control system, the normal feeding of a blast furnace is ensured, the purpose of reducing equipment delay is achieved, and stable and smooth production of the blast furnace is ensured.

Description

technical field [0001] The invention relates to the technical field of photoelectric encoder control of an ironmaking feeding system, in particular to a photoelectric sensor fast alignment device. Background technique [0002] In the ironmaking process, the ore tank feeding control system is one of the key equipment for blast furnace ironmaking. At present, the main hoist, probe, and material distributor in the mine trough feeding control system all use photoelectric encoders to calculate the actual position of the material truck, the height of the material surface, the number of turns of the material and the angle of the material. When the photoelectric encoder When a fault occurs, such data will not be displayed normally, which will affect the normal smelting of the blast furnace; in order to ensure the stable production of the blast furnace, when the photoelectric encoder fails, it is necessary to quickly replace the faulty photoelectric encoder. Before the photoelectric...

Problems solved by technology

However, since the cables of the photoelectric encoders currently used are only red and yellow, it is difficult, time-consuming and labor-intensive to calibrate the photoelectric encoder. It takes at least 30 hours to complete the calibration operation of a photoelectric encoder. Minutes, and the accuracy rate cannot be guaranteed, which greatly affects the stable production of the blast furnace
