具体实施方式 Detailed ways

Connect with the meter reading center.
如图2所示，智能表主要由传感器、信号调理电路、MCU、ZigBee模块、电源部分等组成，其中MCU通过传感器、相应的信号调理电路对计量对象的脉冲信号进行采集、处理并存储。本文重点介绍MCU与ZigBee模块之间的通信，其它部分的通信可采用现有的脉冲表技术实现。智能表具有数据采集、存储，接收指令和发送数据的功能，可对计量对象进行计量、存储数据，或接收中心节点发送的指令并按照指令的要求完成相应的动作。 As shown in Figure 2, the smart meter is mainly composed of sensors, signal conditioning circuits, MCU, ZigBee modules, power supply parts, etc., wherein the MCU collects, processes and stores the pulse signals of the measurement objects through sensors and corresponding signal conditioning circuits. This article focuses on the communication between the MCU and the ZigBee module, and other parts of the communication can be realized using the existing pulse meter technology. The smart meter has the functions of data collection, storage, receiving instructions and sending data. It can measure and store data for measurement objects, or receive instructions sent by the central node and complete corresponding actions according to the requirements of the instructions.
ZigBee射频模块采用飞卡尔思开发的MCl3192芯片，符合802.15.4标准，具有标准的4线SPl、可编程的时钟、可编程的输出功率、超低功耗、多种工作方式等特性，支持星型和网状网络，工作于2.4GHz频段。ZigBee模块内部主要集成了模拟接收发射、数字调制解调、片内频率合成、电源管理、接口等部件，以及33个可以通过SPl接口访问的16位寄存器。 The ZigBee radio frequency module adopts the MCl3192 chip developed by Fecals, conforms to the 802.15.4 standard, has the characteristics of standard 4-wire SPl, programmable clock, programmable output power, ultra-low power consumption, and multiple working modes, and supports satellite Type and mesh network, working in the 2.4GHz frequency band. The ZigBee module mainly integrates analog receiving and transmitting, digital modulation and demodulation, on-chip frequency synthesis, power management, interface and other components, as well as 33 16-bit registers that can be accessed through the SPl interface.
MCU选用飞卡尔思的MC9S08GB60芯片，此芯片与Mcl3192有良好的兼容性，可提供较稳定的技术支持，是一款8位、低功耗、高性能的微处理器。MC9S08GB60芯片具有60kB的Flash和4kB的RAM空间，足够存放ZigBee的协议栈，以及运行简单的应用程序。MC9S08GB60有多种工作模式，有8个10位A/D转换器，多个I/O数据线，2个串行通信接口(SCI)和标准的4线串行外围接口(SPI)。 The MCU uses the MC9S08GB60 chip from Flycars, which has good compatibility with Mcl3192 and can provide relatively stable technical support. It is an 8-bit, low-power, high-performance microprocessor. MC9S08GB60 chip has 60kB of Flash and 4kB of RAM space, enough to store ZigBee's protocol stack and run simple applications. MC9S08GB60 has multiple working modes, there are 8 10-bit A/D converters, multiple I/O data lines, 2 serial communication interfaces (SCI) and standard 4-wire serial peripheral interface (SPI).
在距中心节点较远的地方还设置有数据采集点，数据采集点在无线通信网络中主要充当中继器，将中心节点发送的指令转发给终端智能表，或将终端智能表的数据上传给中心节点，从而使网络具有延伸性，传输的距离更远。通信时，数据采集点对接收到的数据进行解析．并判断地址包含在自己的路由表中时，则为接收的数据选择最佳路径，并转发出去，路由算法采用AODV，这些功能可通过ZigBee协议的网络层实现。数据采集点主要由ZigBee模块、微控制器、存储模块等部分组成。数据采集点也采用ZigBee协议，MCU上集成了ZigBee协议，应用层软件主要实现串口初始化、MCl3192的参数设置、数据的接收与转发。 There is also a data collection point far away from the central node. The data collection point mainly acts as a repeater in the wireless communication network, forwarding the instructions sent by the central node to the terminal smart meter, or uploading the data of the terminal smart meter to the terminal smart meter. The central node makes the network extensible and the transmission distance is longer. During communication, the data collection point analyzes the received data. And when judging that the address is included in its own routing table, it selects the best path for the received data and forwards it out. The routing algorithm uses AODV, and these functions can be realized through the network layer of the ZigBee protocol. The data acquisition point is mainly composed of ZigBee module, microcontroller, storage module and other parts. The data collection point also adopts the ZigBee protocol. The MCU integrates the ZigBee protocol. The application layer software mainly realizes serial port initialization, MCl3192 parameter setting, and data receiving and forwarding.
基于ZigBee技术的网络有3种：星型网络、网状网络、簇型网络。通常小区中使用星型网络即可形成一个由中心节点和终端智能表组成的抄表系统无线网络。考虑列小区中有的智能表离中心节点较远，数据传输可靠性低，因此，采用网状网络。智能表、数据采集点、中心节点之间采用网状网络进行连接，大大提高了整个抄表系统的可靠性和传输速度。 There are three types of networks based on ZigBee technology: star network, mesh network, and cluster network. Usually, a star network can be used in the community to form a meter reading system wireless network composed of central nodes and terminal smart meters. Considering that some smart meters in the residential area are far away from the central node, the reliability of data transmission is low, so a mesh network is adopted. Smart meters, data collection points, and central nodes are connected by a mesh network, which greatly improves the reliability and transmission speed of the entire meter reading system.
中心节点是ZigBee网络中的协调器，负责启动、配置、协调整个ZigBee无线网络以及整个小区与抄表中心的数据传输。中心节点通过以太网或GPRS等通信网络把数据上传到抄表中心。可见，在网络中，中心节点又相当于一个接入点，需要进行ZigBee无线网与其它网络的协议转换。总的来说，中心节点是负责终端智能表的管理及协调ZigBee无线网与其它网络之间通信的关键部件。 The central node is the coordinator in the ZigBee network, responsible for starting, configuring, and coordinating the entire ZigBee wireless network and the data transmission between the entire community and the meter reading center. The central node uploads the data to the meter reading center through communication networks such as Ethernet or GPRS. It can be seen that in the network, the central node is equivalent to an access point, which needs to perform protocol conversion between the ZigBee wireless network and other networks. Generally speaking, the central node is responsible for the management of the terminal smart meter and the key components for coordinating the communication between the ZigBee wireless network and other networks.
中心节点主要由ZigBee模块、32位的嵌入式微处理器、存储模块及外嗣部分等组成。中心节点定期查询、自动抄写各智能表的数据。将数据保存在存储器中，供抄表中心定期读取。因此，中心节点需要较大容量的存储器，一般需外扩存储器。 The central node is mainly composed of ZigBee module, 32-bit embedded microprocessor, storage module and external heir. The central node regularly queries and automatically transcribes the data of each smart meter. Store the data in the memory for periodic reading by the meter reading center. Therefore, the central node needs a large-capacity memory, and generally needs to expand the memory.
考虑到终端智能表的ZigBee模块长时间处于非工作状态，本实用新型的中心节点与终端智能表之间采用信标使能方式通信。中心节点定时广播信标帧，网络中的设备均通过中心节点发出的信标帧完成同步，且设备之间按基于时槽的CSMA—CA信道访问机制进行通信。终端设备和数据采集点的射频模块只在广播信标帧时被唤醒，并侦听信标中的地址。如果没有侦听到本地址，则转入休眠状态；如果含有设备本身的地址，则终端设备向中心节点发送一个数据帧，中心节点收到数据帧后即发送一个确认帧给智能表。中心节点对数据进行校验，若正确，则要求下一个智能表发送数据；若中心节点未在规定时间接收到数据、或接收到的数据校验错误，则要求智能表重新发送数据。智能表如果未在规定的时间内接收到确认帧，则智能表重新发送数据，直到确认为止。中心节点与终端智能表之间采用信标使能方式通信，更加节能，效率更高。 Considering that the ZigBee module of the terminal smart meter is in a non-working state for a long time, the communication between the central node and the terminal smart meter of the utility model adopts a beacon enabling mode. The central node regularly broadcasts beacon frames, and the devices in the network are synchronized through the beacon frames sent by the central node, and the communication between devices is based on the CSMA-CA channel access mechanism based on time slots. The radio frequency modules of the terminal equipment and the data collection point are only awakened when the beacon frame is broadcast, and listen to the address in the beacon. If the address is not detected, it will enter the dormant state; if it contains the address of the device itself, the terminal device will send a data frame to the central node, and the central node will send a confirmation frame to the smart meter after receiving the data frame. The central node verifies the data, and if it is correct, the next smart meter is required to send the data; if the central node does not receive the data within the specified time, or the received data is verified incorrectly, the smart meter is required to resend the data. If the smart meter does not receive the confirmation frame within the specified time, the smart meter will resend the data until it is confirmed. The communication between the central node and the terminal smart meter adopts the beacon enabling method, which is more energy-saving and more efficient.
传输单元在抄表中心和中心节点间建立连接桥梁，将抄表中心的指令传送到中心节点，再将中心节点的数据传送到抄表中心；抄表中心通过传输单元向中心节点发出指令，对中心节点传来的数据进行分析、整理、计算、显示、打印。 The transmission unit establishes a connection bridge between the meter reading center and the central node, transmits the instructions of the meter reading center to the central node, and then transmits the data of the central node to the meter reading center; the meter reading center sends instructions to the central node through the transmission unit, and the The data transmitted from the central node is analyzed, sorted, calculated, displayed, and printed.
传输单元可以采用GPRS，或CDMA，或以太网。GPRS是目前解决移动通信信息服务的一种较完美的业务，它是基于GPRS以数据流量计费、覆盖范围广泛、数据传输速度更快。GPRS的推出，为行业和企业用户开展无线管理提供了基础设施平台，为推动移动管理的应用和发展创造了有利条件。与有线网络相比， GPRS网络具有租用费用低、移动信息监管，不受地域制约等优点。 The transmission unit can adopt GPRS, or CDMA, or Ethernet. GPRS is a relatively perfect business to solve mobile communication information services at present. It is based on GPRS to charge by data flow, with wide coverage and faster data transmission speed. The launch of GPRS provides an infrastructure platform for industry and enterprise users to carry out wireless management, and creates favorable conditions for promoting the application and development of mobile management. Compared with the wired network, the GPRS network has the advantages of low rental cost, mobile information supervision, and no geographical restrictions.
本实用新型采用ZigBee技术，具有协议简单，无需布线，快速组网，传输可靠，数据安全性高等特点，实现数据自动监控、上传，解决了水、电、气三表采用传统的手工和半手工方式抄送存在的费时、费力、费用高等问题，实现更加方便的远程自动抄表、网络查询、缴费。 The utility model adopts ZigBee technology, which has the characteristics of simple protocol, no need for wiring, fast networking, reliable transmission, high data security, etc., realizes automatic data monitoring and uploading, and solves the problem of using traditional manual and semi-manual methods for water, electricity and gas meters. The time-consuming, labor-intensive, and high-cost problems that exist in copying methods can realize more convenient remote automatic meter reading, network query, and payment.
