Detection device for monitoring operation condition of flap door

Abstract

The invention relates to a detection device for monitoring the operation condition of a flap door. The detection device is characterized by comprising an encoder and an upper computer, the encoder isfixedly installed over a machine core transmission shaft of the gate machine and used for detecting relative position information of the gate machine flap door and sending the relative position information of the gate machine flap door to the upper computer through a serial port line connected with the encoder. The upper computer performs gate rushing judgment, initial setting of the gate positionand self-detection of the gate according to the obtained relative position information of the gate flapping door, and sends a corresponding control signal to the gate movement. The encoder is connected with the upper computer through the serial port line, and the encoder and the gate board card are two independent parts, so that a plurality of parts are prevented from being arranged on the boardcard, the board card is greatly reduced, and the rejection rate of the board card is reduced. Therefore, the method can be widely applied to the field of gate flap door control.

Description

technical field [0001] The invention relates to the field of gate flapping gate control, and belongs to the fields of rail transit, ticket sales and inspection services, building and specific place security access control, and venue access control, and in particular relates to a detection device for monitoring the operation of flapping gates. Background technique [0002] As the main equipment of the "automatic ticket gate" in the "automatic fare collection system AFC", the gate is also a channel blocking device, which is widely used in subway gate systems and fare gate systems. [0003] At present, most of the existing gates are controlled by an integrated embedded system. However, there are many problems that cannot be solved in practical application of such gates. These issues can be listed as follows: [0004] (1) The data that the gate needs to receive and send is relatively complex, and there are many components and modules that need to be carried on a board, resultin...

AI Technical Summary

Problems solved by technology

[0004] (1) The data that the gate needs to receive and send is relatively complex, and there are many components and modules that need to be carried on a board, resulting in a high scrap rate of the board;

[0005] (2) The integrated board has a large area and requires a high internal space of the gate;

[0006] (3) As the actual needs continue to change, the functions of the gates also need to be changed, and the integrated board needs to replace the entire board in the process of upgrading, and the scalability is poor;

[0007] (4) A large amount of data exchange is required on one board, the possibility of data interference by noise is high, and the accuracy of data transmission is poor;

[0008] (5) Existing boards cannot easily and efficiently monitor the operating status of the gate flapping gate
