我也想了解这个问题，有没有哪个大侠详细解答一下呢？

1、停车场控制主板采用TCP/IP通讯方式是发展的必然趋势，一般用户在RS485和TCP/IP之间选择，都会选择TCP/IP主板。

2、就我们公司停车场产品而言，采用TCP/IP通讯的主板和采用其他通讯方式的主板价格上并无差异。

3、客户选择TCP/IP主板的最终目的是方便布线和保证系统的稳定运行；TCP/IP控制主板和RS485主板最大的区别在于布线方式和通讯方式，TCP/IP主板直接通过网线连接至交换机，RS485主板需通过485总线连接到就近的停车场工作站电脑，通过工作站电脑与停车场服务器或其他出入口控制主板通讯；采用TCP/IP主板可以不依赖停车场工作站电脑运行，直接与服务器或其他工作站直接通讯。

4、采用TCP/IP通讯，停车场主板传输速率增大至10/100M BASET，停车场主板运行响应时间更快；TCP/IP技术的引入，使得停车场主板可以传输更多的数据，未来的停车场主板可能会集成摄像机接入、车牌自动识别、语音对讲等诸多功能。
