二、   道闸
2、 Road gate
车辆出入口道闸采用深圳捷顺生成的JSDZ0203数字式道闸，该道闸采用先进的直流伺服技术和全电路无触点控制技术，使整机运行更加平稳、可靠。而且采用了数字化电路自学习检测功能，有效地杜绝砸车现象，使系统运行更安全可靠。并配备了标准的外接电气接口，可配置车辆检测器以及上位机，实现系统的自动控制。可广泛适用于道路管理、道路收费及停车场管理等系统中。
The JSDZ0203 digital barrier gate generated by Shenzhen Jieshun is adopted at the vehicle entrance and exit. The barrier gate adopts advanced DC servo technology and full circuit contactless control technology to make the whole machine run more stably and reliably. Moreover, the digital circuit self-learning detection function is adopted to effectively eliminate the phenomenon of vehicle smashing, which makes the system run more safely and reliably. It is equipped with standard external electrical interface, and can be configured with vehicle detector and upper computer to realize automatic control of the system. It can be widely used in road management, road toll collection, parking lot management and other systems.
