摘要：【中文】本发明涉及一种用于监测拍打门运行情况的检测装置，其特征在于：其包括编码器和上位机；所述编码器固定安装在闸机的机芯传动轴的正上方，用于对闸机拍打门的相对位置信息进行检测，并通过与其相连的串口线将闸机拍打门的相对位置信息发送到所述上位机；所述上位机根据得到的闸机拍打门的相对位置信息进行闯闸判断、闸机位置的初始化设置以及闸机的自行检测，并发送相应控制信号到闸机机芯。本发明通过串口线将编码器与上位机进行相连，编码器与闸机板卡为独立的两个部分，避免了板卡上设置多个部件，使得板卡化大为小，降低板卡废品率。因此，可以广泛应用于闸机拍打门控制领域。 【EN】The invention relates to a detection device for monitoring the running condition of a flap door, which is characterized in that: the device comprises an encoder and an upper computer; the encoder is fixedly arranged right above a machine core transmission shaft of the gate machine and used for detecting the 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; and the upper computer judges the gate break, initializes the position of the gate and automatically detects the gate according to the obtained relative position information of the gate shot by the gate, and sends a corresponding control signal to the core of the gate. According to the invention, 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 the board card is prevented from being provided with a plurality of parts, the board card is greatly miniaturized, and the rejection rate of the board card is reduced. Therefore, the gate flap valve can be widely applied to the field of gate flap valve control.
