【摘要】：随着国内城市化进程的持续加快,城镇污水排放量也正以惊人的速度在逐年攀升,这使得污水处理系统的扩展迫在眉睫。目前国内绝大多数的污水处理控制系统都建立在现场总线和工业以太网的基础上,在新增设备时都需要重新敷设电缆,施工难度大且施工周期长。鉴于此,本文提出采用无线通信技术来解决新增设备的接入问题。在对常见几种无线通信技术进行研究与分析后,本文首先确定以ZigBee网络作为扩展系统的数据传输通道,然后在对曝气生物滤池污水处理工艺与传统污水处理系统结构分析的基础上,制定了系统的无线通信技术方案。论文的研究内容包括新增设备的数据采集、ZigBee通信网络的构建及上位机监控系统设计。根据污水处理现场干扰状况与成本考量,本文选用单片机与模数转换芯片作为数据采集器件。通信网络构建方面,本文采用顺舟SZ05模块和顺舟SZ02模块作为网络设备的数据收发器,从而实现控制中心与现场的双向数据交换。此外,本文还利用工控组态软件对上位机监控系统进行了设计。在整体设计方案的基础上,本文分别从硬件层面和软件层面对污水处理无线通信系统设计方案进行详细地阐述并且对上位机监控系统的设计过程也展开具体介绍。最后,本文通过搭建的系统调试平台进行了相关数据的传输实验,进而验证了系统方案的可行性与实用性。本文的研究创新点在于:利用ZigBee技术在污水处理现场搭建了一个结构简单、稳定可靠的无线数据传输系统,该系统可有效地解决现有污水处理系统的设备扩展问题,进而节约投资并提高污水处理系统的工作效率。
[Abstract]:With the continuous acceleration of urbanization in China, urban sewage discharge is increasing year by year, which makes the expansion of sewage treatment system imminent. At present, most of the domestic sewage treatment control systems are based on the field bus and industrial Ethernet. When the equipment is added, the cable needs to be re-laid, so the construction is difficult and the construction period is long. In view of this, this paper proposes to use wireless communication technology to solve the problem of access to new devices. After the research and analysis of several common wireless communication technologies, this paper first determines that the ZigBee network is used as the data transmission channel of the extended system. Based on the analysis of biological aerated filter wastewater treatment process and the structure of traditional sewage treatment system, the wireless communication technology scheme of the system is developed. The research contents of this paper include the construction of ZigBee communication network and the design of monitoring system. According to the interference situation and cost consideration of sewage treatment site, this paper chooses single chip computer and A / D conversion chip as data acquisition device. In the aspect of communication network construction, this paper adopts SZ05 module and SZ02 module as the data transceiver of the network equipment, thus realizing the two-way data exchange between the control center and the field. In addition, this paper also uses industrial control configuration software to design the upper computer monitoring system. On the basis of the overall design scheme, the design scheme of wireless communication system for sewage treatment is described in detail from the hardware level and the software level, and the design process of the upper computer monitoring system is also introduced in detail. Finally, the system debugging platform is used to carry out the data transmission experiment, and the feasibility and practicability of the system scheme are verified. The research innovation of this paper lies in: using ZigBee technology to set up a simple, stable and reliable wireless data transmission system in sewage treatment site, this system can effectively solve the problem of equipment expansion of the existing sewage treatment system. Then the investment is saved and the working efficiency of sewage treatment system is improved.
