Integrated rail transit screen door machine controller

Abstract

The invention discloses an integrated rail transit screen door machine controller. A direct-current brushless motor drive module is connected with a central processor through an isolating circuit; the central processor controls the operation of the motor by means of the direct-current brushless motor drive module and a three-phase full-bridge circuit; the central processor is connected with a LonWorks communication module through an isolating circuit, and the LonWorks communication module is connected with a LonWorks bus through a LonWorks communication transmission transformer; the central processor is connected with a CAN (controller area network) communication module through an isolating circuit, and the CAN communication module is directly connected with a CAN bus; the external input command signal of a control unit is inputted into signal conditioning circuits via a signal bus to be conditioned and then transmitted to the central processor via isolating circuits; and the status indication signal of the central processor is transmitted to the control unit via isolating circuits and drive circuits. The integrated rail transit screen door machine controller is small in size, highly integrated and highly stable, and has a self-test function, all the circuits are isolated from one another, and the integrated rail transit screen door machine controller is easy to maintain.

Description

technical field [0001] The present invention relates to an improvement of a controller for a rail transit screen door operator, in particular to a highly integrated integrated rail transit screen door operator controller integrating control and communication, which belongs to the controller for rail transit screen door operators equipment technology field. Background technique [0002] At present, the known door machine controllers for rail transit screen doors use independent electric door controllers, independent control signal transceivers and independent monitoring and communication devices. Three independent devices take up a lot of space. The three devices are connected by connectors, and the connectors need to use high-reliability connectors, which are expensive. Moreover, due to the connector connection, there is a risk of communication errors due to poor contact. Each device uses a separate CPU, resulting in higher costs. The three devices need to be maintained ...
