基于CAN总线技术的供暖计量系统设计

Design of Heating Metering System Based on CANbus Technology

现场总线技术是信息技术与控制技术的融合,是新一代控制技术的标志。CAN总线协议符合现场总线技术发展的趋势,是目前应用最广泛、最有前途的几种现场总线之一。将CAN总线技术用于传统控制系统的改造是目前国内现场总线技术应用的重点。随着国家对环境保护重视程度的不断提高以及供暖计费体制改革的不断深入,老旧住宅集中供暖计量系统的改造是必要的。本文完成了一种基于CAN总线技术的供暖计量系统的设计,该系统具有不必改变现有供暖管线且施工量小,对住户影响小的特点,符合住宅供暖系统改造的要求。

Fieldbus technology is the merge of information and control technology. It has become the symbol of the new generation control technology. CANbus protocol that complying with the trend of the technology development is one of the most promising and extensively used fieldbus. Applying CANbus teehnology in the remake of traditional control system is focal point of fieldbus application in the domestic. With the enhancing of environmental protection vigilance and the reform of heating valued management system in our country,the remake of central heating metering system in old housing is very necessary. The thesis implemented the design of a heating metering system in housing based on CANbus technology. The system has the characteristics of no changes of existing heating pipeline and the disturb to the resident is least. It is fit for the remake of heating metering system in old housing.
