个人认为未来楼控很难作为一个单独的控制器种类存在，而会被其它产品给吞并，例于PLC。
数采行业因为受到了GPRS、GSM等业务的影响，正出现一次比较大的变革，特别是在远距离方面，传统的MODEM、RTU方式正受到很大的冲击，在我们经手的很多环境监控、管道监控、路灯节能、水文监控方面很少有客户能经受GPRS DTU的诱惑。DTU的基于网络和透明通信方式深受大家的喜爱，只是目前DTU的价格相对而言还是比较高，如果能掉到GSM MODEM的价格就比较合适了。除此之外移动对于数据业务的支持还是不够，早期还可以用神州行卡，现在已全部关闭了，只能用全球通，而全球通每月50元的月租实在让人很恼火，一个城市的路灯节能控制器如果全部上GPRS，假设有1000个点，那么每个月就需要5万元的开支，还不包括流量的收费，对于公共事业这还算好，对于工厂或者电梯的监控就很难受了。
无论如何GPRS DTU是一个方向，单节点月费用不超过二十元，单节点价格低于400元时将是其大行其市的日子。
2、未来的控制系统
前面讲了这么多历史，下面看看我心目中的未来控制器。
经过FCS和现场总线的浪潮后，各大公司好像都累了，这几年大家都在底头为下一代的控制器做各种研发和准备（包括理论和实践），在这个过程中，我们与东芝、AB、思博等公司进行了比较深入的合作和交流同时也有了一些自己的想法：
我认为将来的控制器将会分为以下三类：
类：
单芯片控制器：
单点价格在10元左右，支持可编程，可以带现场总线或者网络。只需要加上很少的外部电路就可以实现一个可编程控制器的功能。从某种意义上来说这将会改变未来的硬件研发方式，大多数的研发工程师将不用C语言开发产品，而会使用图形化的软件开发，工程师与底层的联系越来越远，软件的模块化、图形化、表格化将是一种趋势。
德维森的V60系列可编程智能继电器产品无疑是这种方案的一个实行者，不需要太多复杂功能，成本要相当低，联网功能可选，这样少点数的PLC将是一种比较现实的产品。
