An Intelligent Lifting Column Control System

Abstract

The invention discloses an intelligent lifting column control system, which includes a power supply unit, an intelligent processing unit, an anti-mis-press module, a control signal processing unit and a lifting control module. The power supply unit supplies power for the entire system, and the anti-mis-press module is used to prevent For the control signal generated by mistakenly pressing the button, the control signal processing unit is used to obtain the real control signal, which includes an interference signal suppression module and an interference signal filtering module. The interference signal suppression module is used to eliminate the interference signal on the circuit, the interference signal The filtering module is used to filter the interference signal generated by the key, and the lifting control module controls the lifting column of the lifting bollard to lift according to the real control signal. The invention can minimize the collision accidents caused by misoperation of the lifting column due to misoperation of the button and mistaking the interference signal as an effective control signal, and greatly improves the stability and safety of the control system of the lifting column.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to an intelligent lifting column control system. Background technique [0002] The lifting column plays the role of temporarily blocking passages and controlling the entry and exit of vehicles in special areas. It is mainly used in places such as government agencies, toll stations, parking lots, and pedestrian streets. By restricting passing vehicles, it effectively guarantees traffic order and major facilities. and site safety. [0003] Under normal circumstances, the lifting column is shrunk and hidden underground, which does not affect the normal passage of vehicles. In case of emergency, the management personnel will issue instructions through the control button, so that the lifting column will start instantly and extend out of the ground within a few seconds to achieve Control lanes, close gates and other requirements, prevent vehicles from forcibly punching cards t...

AI Technical Summary

Problems solved by technology

[0004] In the current lifting column, when the button is touched or pressed by mistake, the control command issued by the button will cause the lifting column to start, causing the lifting column to rise by mistake and a collision accident occurs. Moreover, when the lifting column control system receives the control signal, It is also easy to mistake the interference signal for an effective control signal, resulting in misoperation, making the stability and safety of the lifting column control system poor

[0005] In addition, most of the existing lifting columns only have conventional lifting control functions, which cannot meet the different needs of users

At the same time, the current lifting column control system basically adopts PLC control. Because it uses switching power supply for power supply, the system works relatively stable, but the switching power supply used has disadvantages such as low safety level, large amount of electromagnetic radiation, and high cost. It is a general-purpose component, and only has the function of lifting control, which cannot meet the more control requirements of the lifting column, and the cost of use is also higher
