Embodiment 1

[0035] Embodiment 1: The subway platform door separates the platform from the train running area, and a lookout light strip is set on or near the end door column of the platform door for the driver to observe whether there are foreign objects between the train and the platform door. This embodiment provides a platform door system lookout light strip control device, such as figure 1 and figure 2 As shown, the device includes a power supply module, a micro control unit (MCU), a door opening and closing detection module, a train position detection sensor, a delay circuit and a lookout light strip control circuit. The train position sensor is used to obtain the train position. The reference to whether there is a foreign object between the platform door is that the lookout light strips are all on. Therefore, in order to avoid other light from affecting the lookout light strips in this embodiment, the train position sensor uses a non-contact sensor that does not produce visible and...

Embodiment 2

[0044] Embodiment 2: The similarities between this embodiment and Embodiment 1 will not be repeated. The difference is that there is a difference in the control circuit of the lookout light belt. Specifically, the switching element of this embodiment is a rheostat switch, such as Figure 6 As shown, the rheostat switch includes a gear box and a rheostat disc. The gear box includes a driving gear 4, a driven gear 5 and a composite driving gear 6. The driving gear meshes with the driven gear, and the composite driving gear and the driven gear are coaxially connected. , the rheostat plate includes the end driven gear, the end driven gear meshes with the composite driving gear, the end driven gear is provided with a carrier plate 1, the carrier plate and the end driven gear are integrally connected, and a sliding rheostat is arranged on the carrier plate , the sliding rheostat is provided with a rheostat slideway 2 and a rheostat sliding piece 3, one end of the sliding rheostat is ...

Embodiment 3

[0046] Embodiment 3: The similarities between this embodiment and Embodiment 2 will not be repeated, and the difference is that, as Figure 7 As shown, the end driven gear of the rheostat switch in this embodiment is driven by a stepping motor 8, and the stepping motor drives the carrier plate 1 to rotate forward or reverse to realize the increase or decrease of the resistance while precisely controlling the rotation In actual use, the rotation speed of the stepping motor can be controlled according to the needs to control the time when the lookout light belt is on or off. It is simple and practical, and can significantly prolong the service life of the LED light.

Abstract

The invention belongs to the technical field of subway lookout lamp strip control, and particularly relates to a platform door system lookout lamp strip control device and method. The device comprisesa micro-control unit, a door opening and closing detection module, a train position detection sensor and a lookout lamp strip control circuit. The output end of the door opening and closing detectionmodule is connected with the input end of the micro-control unit and used for transmitting door opening and closing signals to the micro-control unit. The train position detection sensor is connectedwith the input end of the micro-control unit and is used for transmitting a train position signal to the micro-control unit; the micro-control unit controls an output end signal line to control the connection and disconnection of the lookout lamp strip through a switch element so as to control the on / off of the lookout lamp strip; and by means of the device, the lookout lamp strip can be lightened when a train enters a station, and the lookout lamp strip can be automatically extinguished after the train leaves the station. The lighting time of the lamp strip can be shortened, the influence ofnormal lighting of the lookout lamp strip on the service life of an LED is avoided, and the failure rate of the lamp strip is reduced.

Description

technical field [0001] The invention belongs to the technical field of subway lookout light strip control, and in particular relates to a control device and a control method for a lookout light strip of a platform door system. Background technique [0002] The subway platform door is a high-tech product that integrates architecture, machinery, materials, electronics and information, and is used in subway platforms. The platform door separates the platform from the train running area, and is controlled by the control system to open and close synchronously with the train door to ensure the safety of the train and passengers entering and leaving the station. In order to ensure the normal operation of the train, there is a gap of about 130mm between the train and the platform door. If passengers or other objects are caught in this gap, it will endanger the lives of passengers and have a serious impact on the safe operation of the train. For this reason, a lookout light strip is...
