The invention discloses an electric cylinder control method for a crossing interception system. The electric cylinder control method is achieved through an electric cylinder control system composed of an alternating-current power supply (1), a direct-current power supply (2), a control panel (3), a solid-state relay (4), an electric cylinder (5) and a proximity switch (6). The control panel (3) sends a control instruction according to a button state and a feedback signal of the proximity switch (6), controls the output phase sequence of the solid-state relay (4) and further achieves the purpose of controlling 'extension', 'retraction' and 'stop' of the electric cylinder. The electric cylinder control method is simple, low in cost and high in reliability and is suitable for the crossing interception system which is not high in electric cylinder servo accuracy.
Description
technical field [0001] The invention relates to an electric cylinder control method, in particular to an electric cylinder control method for a crossing interception system. Background technique [0002] In order to achieve precise control of the electric cylinder, the general electric cylinder uses a servo motor in the structure and is equipped with a servo driver, and uses a host computer, an angle sensor or a linear displacement sensor to form a feedback loop to achieve precise control of the displacement of the electric cylinder. This control method is complex in system and high in cost, and is not suitable for a crossing interception system that does not require high precision control of the displacement of the electric cylinder. Contents of the invention [0003] The purpose of the present invention is to provide an electric cylinder control method for a crossing interception system, which solves the problems that the traditional electric cylinder control method is c...
