Fig. 2 is the structured flowchart of intelligence table.
Embodiment
As shown in Figure 1, long-distance meter-reading system based on the ZigBee radio communication function, comprise intelligent table, Centroid, transmission unit, the center of checking meter, described intelligence table links to each other with described Centroid, and described center node links to each other with the described center of checking meter by transmission system.
As shown in Figure 2, the intelligence table is mainly graded and is formed by sensor, signal conditioning circuit, MCU, ZigBee module, power supply unit, and wherein MCU gathers, handles and store the pulse signal of metering object by sensor, corresponding signal conditioning circuit.This paper introduces communicating by letter between MCU and the ZigBee module, and the communication of other parts can adopt existing pulse meter technology to realize.Intelligence table has data acquisition, storage, receives instruction and sends the function of data, can measure, store data to the metering object, or the instruction that sends of receiving center node and finish corresponding action according to the requirement of instruction.
The ZigBee radio-frequency module adopts the MCl3192 chip that flies the Ka Ersi exploitation, meet the 802.15.4 standard, have characteristics such as 4 line SPl of standard, programmable clock, programmable output power, super low-power consumption, several working ways, support star-like and mesh network, work in the 2.4GHz frequency range.The ZigBee inside modules is mainly integrated simulates parts such as receiving frequency synthesis in emission, digital modulation and demodulation, the sheet, power management, interface, and 33 can be by 16 bit registers of SPl interface accessing.
MCU selects the MC9S08GB60 chip that flies Ka Ersi for use, and this chip and Mcl3192 have favorable compatibility, and more stable technical support can be provided, and is a 8, low-power consumption, high performance microprocessor.The MC9S08GB60 chip has the Flash of 60kB and the ram space of 4kB, enough deposits the protocol stack of ZigBee, and moves simple application program.MC9S08GB60 has multiple mode of operation, and 8 10 A/D converters are arranged, a plurality of I/O data lines, 4 line serial peripheral interface (SPI) of 2 serial communication interfaces (SCI) and standard.
The place far away at the distance Centroid also is provided with data collection point, data collection point mainly serves as repeater in cordless communication network, the instruction that Centroid is sent is transmitted to the terminal intelligent table, or give Centroid with the data upload of terminal intelligent table, thereby make network have extensibility, the distance of transmission is farther.During communication, data collection point is resolved the data that receive. and judge when address packet is contained in oneself the routing table, then select optimal path for the data that receive, and forward, routing algorithm adopts AODV, and these functions can realize by the network layer of ZigBee agreement.Data collection point mainly partly is made up of ZigBee module, microcontroller, memory module etc.Data collection point also adopts the ZigBee agreement, the last integrated ZigBee agreement of MCU, and application layer software is mainly realized the parameter setting of serial ports initialization, MCl3192, reception and the forwarding of data.
Network based on the ZigBee technology has 3 kinds: Star Network, mesh network, bunch type network.Usually use Star Network can form a kilowatt meter reading-out system wireless network of being formed by Centroid and terminal intelligent table in the residential quarter.Consider that the intelligence table decentering node that has in the row residential quarter is far away, data transmission credibility is low, therefore, adopts mesh network.Adopt mesh network to connect between intelligence table, data collection point, the Centroid, improved reliability and the transmission speed of whole kilowatt meter reading-out system greatly.
Centroid is the telegon in the ZigBee network, is responsible for starting, dispose, coordinating the data transmission at whole ZigBee wireless network and whole residential quarter and the center of checking meter.Centroid by communication networks such as Ethernet or GPRS data upload to the center of checking meter.As seen, in network, Centroid is equivalent to an access point again, need carry out the protocol conversion of ZigBee wireless network and other network.Generally speaking, Centroid is the critical component of being responsible for the management of terminal intelligent table and coordinating to communicate by letter between ZigBee wireless network and other network.
Centroid mainly is made up of ZigBee module, 32 embedded microprocessor, memory module and the outer part etc. of succeeding.The data of each intelligence table are regularly inquired about, copied automatically to Centroid.Save the data in the storer, for regularly reading at the center of checking meter.Therefore, Centroid needs the storer of larger capacity, generally needs outer extension memory.
The ZigBee module of considering the terminal intelligent table is in off working state for a long time, adopts the beacon mode of enabling to communicate by letter between Centroid of the present utility model and the terminal intelligent table.Centroid fixed time broadcast beacon frame, the beacon frame that the equipment in the network all sends by Centroid is finished synchronously, and communicates by the CSMA-CA channel access mechanism based on time slot between the equipment.The radio-frequency module of terminal device and data collection point only is waken up when broadcast beacon frame, and the address in the listen for beacons.If do not listen to this address, then change dormant state over to; If contain the address of equipment itself, then terminal device sends a Frame to Centroid, and Centroid receives that namely sending an acknowledgement frame behind the Frame shows to intelligence.Centroid carries out verification to data, if correct, then requires next intelligence table to send data; If the data check mistake that Centroid does not receive data at the appointed time or receives then requires the intelligence table to resend data.If the intelligence table does not receive the confirmation frame in official hour, then the intelligence table resends data, till confirming.Adopt the beacon mode of enabling to communicate by letter between Centroid and the terminal intelligent table, more energy-conservation, efficient is higher.
The transmission unit bridge that connects between the center of checking meter and Centroid is sent to Centroid with the instruction at the center of checking meter, and the data with Centroid are sent to the center of checking meter again; The center of checking meter is sent instruction by transmission unit to Centroid, and the data that Centroid transmits are analyzed, put in order, calculate, show, printed.
Transmission unit can adopt GPRS, or CDMA, or Ethernet.GPRS is solve mobile comm message service at present a kind of perfectly professional, it be based on GPRS with data traffic charge, cover a wide range, data rate is faster.The release of GPRS is for industry and enterprise customer carry out the radio management facility platform that provides the foundation, for advantage has been created in the application and the development that promote mobile management.Compare with cable network, GPRS network has that rent is low, the mobile message supervision, is not subjected to advantages such as region restriction.
The utility model adopts the ZigBee technology, it is simple to have agreement, need not wiring, quickly networking, transmission is reliable, characteristics such as data security height, and the realization data are monitored automatically, are uploaded, problems such as time-consuming, the effort that has solved that water, electricity, gas three tables adopt traditional craft and semi-hand mode to make a copy for to exist, expense height realize convenient remote automatic meter reading, network inquiry, pay the fees.
